Drywall imported from China during the homebuilding boom years of 2004 and
2005 was made with waste materials from scrubbers on coal-fired power plants. Those materials leak into the air as gases and combine with the moisture on an air conditioning coil to create sulfuric acid, which appears to be dissolving solder joints and copper tubing - creating leaks, blackening the coils and even causing the system to fail. http://www.news-press.com/article/20.../81220026/1076 Best Regards Tom. |

There should be no free sulfur compounds present to create sulfuric acid---it is bound with the limestone that is used to neutralize sulfur dioxide, making gypsum in the process. Harold |

I don't (and wouldn't) doubt the possibility of other contaminants, Tom. I think we've seen ample evidence of that already by the other products that have proven to be troublesome---just trying to shed some light on the idea that it is common practice for drywall manufacturers to use the salvaged gypsum from that source. A workman was killed here recently when a huge piece came off one of the scrubbers and hit him. They were salvaging the gypsum when it happened. I wonder, how safe are we, even with board made in the US? It seems to me that many corporations have placed a higher priority on profit than anything else. At this point in time, nothing surprises me. Harold |

It seems the Chinese make many different levels of "quality". Much is
junk and some is actually stuff that meets or exceeds standards as set by the country to which it is to be exported too. I remember that in those years there were shortages of alot of building materials, as the construction boom, and the recovery from several large hurricanes was ongoing at the time. So a lot of this was likely overlooked in the interest of expediting contracts and repairs.

With globalism being all the rage don't expect our government to ban trade with any country. We are all expendable for the sake of profits.

This is what i wrote in response to the latest news press article.
Once again the claims of Engel homes is unfounded except for removing the drywall. Fosters sealant paint has been added to all the surfaces of a tested home with the drywall in question and did not work. The odor came back after the smell of the paint went away and certain metals continued to pit. I don't under stand why the newspress keeps using Lennar as if they are the only one with a real problem. As far as i can tell almost all the builders have this problem to a certain degree and not at small %s. "Scientific testing shows no indication of any health risks to our homeowners. Lennar has been working with our homeowners on long-term solutions based on the specific testing of their homes" Yes certain ASTM and OSHA testing has been conducted but this is a cumulative issue and not a short term exposure, so no true heath study has been conducted to date meaning testing for chronic exposures. This article is right about not panicking and to work with your builder, it's just no one has attempted correct type of testing including corrosion studies to analytically find out what is actually corroding the specific metals and comparison studies with the affected drywall and regular US made drywall without the stated issues. Here are a few terms you should look for and research. KNAUF Flue Gas Desulphurization Pyrophoric Oxidation OSHA 1008 & 1011 combined modified long term test NIOSH 7903 Drywall analysis by XRD for Iron Pyrite |

John WELLINGTON, New Zealand (AP) - A Chinese court has declared bankrupt the company at the center of a scandal over tainted milk - blamed for killing six children and sickening almost 300,000 more, one of the company's owners said Wednesday. New Zealand's Fonterra Group said that a court in Shijiazhuang, in China's Hebei province, had issued a bankruptcy order against Sanlu Group Co. in response to a petition from a creditor. Fonterra Chairman Henry van der Heyden said the melamine contamination was "a criminal event," but that Fonterra remained "committed to China." Fonterra, which controls more than 95 percent of New Zealand's milk supply, is the country's largest multinational business, its second-biggest foreign currency earner and accounts for more than 24 percent of the nation's exports. http://www.google.com/hostednews/ap/...pFmzwD958VM580 Crime does pay in china.

Most industrial Chinese lathes over 13" swing Gunner From my admittedly limited knowledge of machining, Gunner is correct - the big Kwacheons (sp) at school are superb, so smooth in operation, quiet, everything works well.. They recently got some new Colchesters - same crappy finish, badly fitting sheet metal, same mechanical design as the 50 year old ones they replaced. Only difference was some fancy electronics, they still had the same annoying "features" they always had. The $20 4 inch Chinese angle grinder is superb, you will get a year or two out of it, and if it gets knocked off from the back of your truck, no big deal. At that price, you have 3 or 4 of em loaded with different disks - saves time and effort. Ditto with most of the rest of their power tools, a lot of contractors here are using the Chinese mitre saws for the same reasons. And for the rest - these are people who build most of the electronics in your lounge room. Including the semiconductors in them. And they don't give a rats arse about supplying data sheets, or selling spares, unless you want to buy a min. of 100,000 units - they don't need to, so they don't .They have put men in space, built supersonic jet fighters, ICBM's and nuclear submarines. And, being pragmatists, and businessmen, (sorta like republicans, I guess) they will sell you any level of quality you want. And if your company in the US wants to screw them down on price to get a bigger retail profit, well, they will happily oblige by making a cheaper, crappier product. (What really annoys me is where a local brand, say, of clothing or footwear and has a reputation for quality built up over generations suddenly moves their manufacturing offshore - still the same price, mind you, but noticeably lower quality. best local example is "Blundstone" workboots, used to be good for 3 winters till they started leaking. Now, made in China, I refuse to buy them. May as well pay a third the price for things that last one year and are openly Chinese.) Thought all this would have been blatantly obvious by now.......(yeh, I know I am ranting, no need to point it out..) Andrew VK3BFA. |

I don't deal with any such machines. Would you deal with industrial size machinery anyway? - I admit I don't, but thats what they have at my trade school, and they are getting more of them. Conversations with the apprentices in my group indicate they cant wait to get rid of the crappy worn out English/ Australian /American junk where they work and get nice new Chinese ones. (As a time honoured tradition, the apprentices get the crappy machines...for obvious reasons) The $20 4 inch Chinese angle grinder is superb, you will get a year or two out of it, and if it gets knocked off from the back of your truck, no big deal. At that price, you have 3 or 4 of em loaded with different disks - saves time and effort. Ditto with most of the rest of their power tools, a lot of contractors here are using the Chinese mitre saws for the same reasons. are they better, or just cheap and diposable? Another recent thread here mentioned angle grinders with slugs of metal in place of bearings. Cheap and disposable - do you need anything else? And for the rest - these are people who build most of the electronics in your lounge room. Including the semiconductors in them. And they not mine, for other people that prefer the 100% off-shore labor and diposable lifestyle, until their job is finally obsolete, I'm sure it's all chinese stuff. How do you know? - ever opened it up, had a look. And unless its 1970's vintage, a LOT of it will be Chinese sourced. And I can only assume you dont have a $40 DVD player... don't give a rats arse about supplying data sheets, or selling spares, unless you want to buy a min. of 100,000 units - they don't need to, so they don't .They have put men in space, built supersonic jet They put more men into mining disasters and kids in collapsed schools than into space. So? - whats that got to do with high end electronics and manufacturing? fighters, ICBM's and nuclear submarines. And, being pragmatists, and businessmen, (sorta like republicans, I guess) they will sell you any level of quality you want. And if your company in the US wants to screw them down on price to get a bigger retail profit, well, they will happily oblige by making a cheaper, crappier product. This here is the issue I have- the junk. I can't think of anything you get that's made in china because it's the "best" or "better" than other sources. Yep, they will sell us junk if we want it.We don't see the high end stuff.And most of us couldn't afford it anyway. And, due to the weirdo capitalist system we mutually run, people will buy on price rather than quality - its a race to the bottom, but hey - thats "market forces".... It doesn't even have to do with china itself. Most stuff you get these days is watered down garbage. I was recently looking for US made copper clad stainless steel pots. Apparently, nobody makes one that's not paper thin or has all the spot weld well marks visible. I don't think any of the Revere or ekco stuff is even made here anymore, or anywhere close to how they were before. Are you REALLY surprised? - you act like a third world customer, you get third world quality...see above point.. Andrew VK3BFA.. |

Most industrial Chinese lathes over 13" swing Gunner From my admittedly limited knowledge of machining, Gunner is correct - the big Kwacheons (sp) at school are superb, so smooth in operation, quiet, everything works well.. They recently got some new Colchesters - same crappy finish, badly fitting sheet metal, same mechanical design as the 50 year old ones they replaced. Only difference was some fancy electronics, they still had the same annoying "features" they always had. Interesting. I don't deal with any such machines. I do, daily. Some of the Polish lathes and East German/Bulgarian/Romanian are prettty good too. Some.

Another recent thread here mentioned angle grinders with slugs of metal in place of bearings. Better than what? Are they a better value than a Metabo? If you like changing disks with great regularity, no they are not better. If you like to keep 3 on hand, one with a cup brush, one with a gross grinder and one with a flap wheel on the bench whenever welding..yes, they are "better" because they are affordable and last a reasonable amount of time.

Somethings you cant get anymore unless its Chinese, or get a mortage on your first born child. Gunner "[L]iberals are afraid to state what they truly believe in, for to do so would result in even less votes than they currently receive. Their methodology is to lie about their real agenda in the hopes of regaining power, at which point they will do whatever they damn well please. The problem is they have concealed and obfuscated for so long that, as a group, they themselves are no longer sure of their goals. They are a collection of wild-eyed splinter groups, all holding a grab-bag of dreams and wishes. Some want a Socialist, secular-humanist state, others the repeal of the Second Amendment. Some want same sex/different species marriage, others want voting rights for trees, fish, coal and bugs. Some want cradle to grave care and complete subservience to the government nanny state, others want a culture that walks in lockstep and speaks only with intonations of political correctness. I view the American liberals in much the same way I view the competing factions of Islamic fundamentalists. The latter hate each other to the core, and only join forces to attack the US or Israel. The former hate themselves to the core, and only join forces to attack George Bush and conservatives." --Ron Marr |

I saw Chinese OEM components for medical equipment etc. at incoming inspection. Quality was whatever the vendor and purchaser agreed on, in these instances quite high. Then the parts were assembled and tested here by hard-working and careful immigrants, many of them Haitian and Cambodian refugees. The engineers and techs were mostly male Europeans like me, or Indian. I think that's due to self- selection or military service, the field is open to anyone. The broadly multinational work force was typical of electronics in New England. When I worked for a defense contractor my boss was Chinese, his was ethnic Russian. It surprises me that people from all over the world are so alike when removed from their culture, even if their ancestors were isolated for 10,000 years. BUT...

Disposable electronics? - I used to have a nice small business fixing things, my remaining customers are "old timers" like myself who still have the mindset that something should, with maintenance, last 20 years,,,,,totally out of sync with modern times - it will be interesting in the years ahead as the generation that is used to "junk and replace" equipment has to cope with hard times....fine if your in the loop, have an income to support it, but....... The $20 4 inch Chinese angle grinder is superb, you will get a year or two out of it, and if it gets knocked off from the back of your truck, no big deal.

Another recent thread here mentioned angle grinders with slugs of metal in place of bearings. Yep, cheap and disposable, and built with sufficient accuracy to be able to do the job. Was speaking with the carpenters who built the back deck on my house - I was surprised they were using a Chinese mitre saw rather than a Hitachi, Dewalt, etc. They explained that the Chinese one was a third the price, lasted as long, and it didn't hurt so much if the apprentice wrecked it or it got stolen from the back of the truck. They do use Dewalt cordless drills, at 5 times the price of the Chinese ones, because, in a professional, all day application, they are superb and WORTH THE MONEY. And when the Chinese start putting decent batteries in theirs, then the situation will change rapidly, no doubt. Hell, I like my clothing to fall apart after 3 washes too. Disposable is great. long life bulbs? scratch that, I like using photographic bulbs rated 3-4 hours wherever I can. Just throw them away and get new ones. Agreed, especially with boots - hate breaking them in, hate only getting a year out of them. But I don't have a choice, the local brand I used to buy has moved to China, while I was happy to pay twice the price of the Chinese ones, and so were a LOT of other people, the company management was more interested in "return to investors" and their own fat bonuses. Our last factory that made light bulbs closed a few years ago - bloody hell, what sort of a so called advanced western country cant even make its own light bulbs? - something is grossly wrong/totally mad here.... not mine, for other people that prefer the 100% off-shore labor and diposable lifestyle, until their job is finally obsolete, I'm sure it's all chinese stuff. Speaker are all from the 90s and made here. Amp is made in the USA in the 1990s, even the electrolytics in are from here. If it blows up, great, it's made to be repaired, not thrown away. So, getting on to 20 years old - and are you REALLY sure where the drivers in your speakers were made? Is it all made here, no, but a reasonable effort was made to support manufacturing here in the USA. It's also nice that the quality is high on lots of these products, so I don't need to throw them away ever 6 months because they wore out. You have to be rich to buy all your stuff back over and over again, hell why not just lease everything from the bank of china instead? No disagreement there - but again, its all getting old, could you replace it with good quality localally made gear? They put more men into mining disasters and kids in collapsed schools than into space. So? - whats that got to do with high end electronics and manufacturing? It means you're dealing with people who don't care about quality or safety. Safety is a form of quality for people. If your people are not important, I can't imagine how important the products you make are. Is this sorta like the banking system? - may not kill people, but do a lot of damage - is that socially responsible too.... you really think that people who can't make building that can hold their own weight care about the quality of export products? Nope, why should they - its called "having a job", and if the silly Westerners will buy crap, so be it. judging from $20 angle grinders with fake bearings, you (or whoever)seem to want junk, and nothing else. I suggest leasing everything if that't the case. Never had a cheap angle grinder with fake bearings - why would they bother, they have modern hi-tech bearing factories - maybe a retailer screwed them down so much they compromised?. And, if it stuffs up, the retailer replaces/refunds it, and writes the cost off against tax. They get crushed and thrown in the dump bin for landfill. Same with even contemporary Japanese electronics. You mentioned a 1998 Sony CD player, know them well. Surprised it hasn't needed a new laser block by now, Sony are OK as the replacement blocks are relatively cheap, and the quality of the rest of the unit makes it worthwhile to do it. My Philips CD player died after 15 years, searched through the used gear shops till I found a Sony that used a KSS210 laser block. Couldn't buy a new CD player, (except as part of a "system") - every salesman tried to get me to buy a DVD player, as it also plays CDs. (High end "golden ears" audiophile stuff excepted - have trouble with the bull**** factor) My wife bought a Yaesu FT60r hand held dual band amateur transceiver - I looked at the box, it was made in China. Was surprised, but shouldn't have been. Regards, Andrew VK3BFA. |
