| 纺织印染助剂对甲醛的限制 Restrictions of textile auxiliaries on formaldehyde 不能使用使直接与皮肤接触的纺织品的甲醛量超过30ppm和使所有其它纺织品的甲醛量超过300ppm的纺织助剂，如含超标甲醛量的羊毛保护剂、固色刑、交联剂、粘合剂等。 It is not allowed to use textile auxiliaries, such as wool protectors, color fixing agents, cross-linking agents, adhesives, etc., which can make the formaldehyde content of textiles directly in contact with the skin exceed 30 ppm and that of all other textiles exceed 300 ppm. 限制纺织染料中游离的和部分能水解产生的甲醛量，保证在织物上游离的和部分能水解产生的甲醛量对直接与皮肤接触的纺织品来说不能超过30ppm，而对所有其它纺织品来说不能超过300ppm。 Limit the amount of free and partially hydrolyzable formaldehyde in textile dyestuffs to ensure that the amount of free and partially hydrolyzable formaldehyde on fabrics can not exceed 30ppm for textiles in direct contact with skin, and 300ppm for all other textiles. 在纺织品中不能用重金属盐（除铁之外）或甲醛作为去色剂或褪色剂。 Heavy metal salts (except iron) or formaldehyde shall not be used as color removers or fading agents in textiles. 三聚氰胺泡沫塑料作为一种新材料，除具有通用泡沫材料的性能外，还具有低密度、低导热性、高燃点、耐湿热稳定性等特性，同时三维网状结构赋予其良好的隔热、吸音降噪、安全卫生、机械加工等性能。另外，三聚氰胺泡沫经高温发泡制成，无残存游离甲醛。成都有机该项目完成了1000m/a三聚氰胺泡沫中试，制备的泡沫性能稳定；形聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 成了100000m/a三聚氰胺泡沫装置的成套工艺技术，已在四川省等地转让两套100000m/a三聚氰胺泡沫技术。 As a new material, melamine foam has the properties of low density, low thermal conductivity, high ignition point and moisture and heat stability. Besides, it has good properties of heat insulation, sound absorption, noise reduction, safety and hygiene, mechanical processing and so on. In addition, melamine foam is made of high temperature foaming without residual formaldehyde. Chengdu organic project completed the 1000m/a melamine foam pilot test, the foam performance was stable, forming a complete set of process technology of 100000m/a melamine foam device, has transferred two sets of 100000m/a melamine foam technology in Sichuan province and other places |
