After on May 26 the hurricane "Katrina" in August, 2005 assails the American New Orleans, federal emergency measures bureau lives by 2,700,000,000 US dollar purchase cabinets and the mobile home to the disaster victims, but this bureau has not listed in detail the building materials in the construction specification the hygienic standard of security, the manufacturer doubts the use inferior lumber and including the formaldehyde material for rushing a job, the result 300,000 disaster victims move in several months later, drops the public health crisis, the partial people have the healthy problem, even some people die.

中新网5月26日电飓风&卡特里娜&2005年8月吹袭美国新奥尔良后，联邦紧急措施署以27亿美元购买货柜和流动房屋给灾民居住，但该署在建造规格上没详列建材的卫生安全标准，制造商为赶工疑使用劣质木材和含甲醛材料，结果30万灾民入住数个月后，堕公共卫生危机，部分人出现健康问题，甚至有人死亡。

The optimum technical parameters were obtained as follows:bromating temperature is 15℃,solvent is methyl arcohol, bromating agent is BrCl,the molar ratio of 4-hydroxy-benzaldehyde to BrCl is 1:1.15,reaction time is 2.5 hours.

其工艺参数优化如下：溴化时反应温度选择15℃，溶剂选择甲醇+乙酸甲酯，溴化剂选择氯化溴，对羟基苯甲醛与氯化溴之比为1∶1.15，反应时间选择2.5个小时，滴溴时间约半个小时。

Through copolymerizing AA and AN in different mole ratio, and compare the PV performance with membrane of PVA acetal membrane, we can concluded that, the separation flux of composite membrane is less than PVA acetal membrane, however, when the mole ratio of AA and AN is 1:1, the separation factor is higher than PVA acetal membrane, from the view of PSI, the composite membrane is better, thats the reason of the hydrophilic functional group and hydrophobic functional group ratio proper, it achieved good balance.

经过研究得到相对最佳的制膜条件：PVA浓度10％，甲醛浓度36％，采用加热到75℃的方法缩醛和制膜，热处理时间为15min；AA与AN的投料摩尔比为1比1左右，复合膜厚为30gm。通过渗透汽化指数的综合衡量，得到对于共聚复合膜最佳的使用温度为50℃左右。

This article introduced the resin finishing woven cottons craft as well as upstream the fabric leaves the formaldehyde content the determination method.

Aiming at the shortcomings of high formaldehyde content and low soaping and crocking fastnesses of currently used pigment printing binder,by60Co-γ radiation polymerization process,the waterborne polyacrylate emulsion containing active keto groups was synthesized from acrylate monomers and diacetone acrylamide.

针对目前所用涂料印花黏合剂存在的色牢度低和甲醛含量高的缺陷，采用钴60-γ辐射法聚合工艺，利用丙烯酸酯单体、双丙酮丙烯酰胺合成出含活性酮羰基的丙烯酸酯乳液；然后同含端酰肼基聚氨酯乳液按一定的比例混合，制备出酮肼交联型丙烯酸酯聚氨酯复合乳液。
