ʻO ka polyether polyurethane acrylate no nā uhi palaki

Huahana Huahana: ZC6202

ʻO ka huahana ZC6202 kahi huahana hōʻailona o ka hui.ʻO kona inoa kemika he polyether polyurethane acrylate.He wai waihoʻoluʻu ʻole a melemele paha me ka maʻalahi a me ka hoʻopili ʻana.Hoʻohana nui ʻia ia no ka pepa, ka uhi plastik a me ka lāʻau adhesion primer.Aromatic polyurethane acrylate

E hoʻohui i ka polyether (polyester) diol a me ka polymerization inhibitor i loko o ka pahu ʻehā port i hoʻolako ʻia me ka mīkini hoʻouluulu, thermometer a me condenser tube, hoʻoulu like, a laila hoʻohui i ka TDI, hoʻonui i ka mahana i 70-80 ℃ no ka pane ʻana no nā hola 1.5, ʻike i ka waiwai NCO, a laila e hoʻohui i ka hydroxyethyl acrylate (hydroxypropyl acrylate), e hoʻohui i ka catalyst, e hoʻomau i ka hopena no nā hola 3, a ʻike i ka waiwai o ka NCO e like me 0. Ua ana ʻia ka viscosity o ka aromatic polyurethane acrylate e ka laʻana, a ua hoʻāʻo ʻia ka hana o ka aromatic polyurethane acrylate. ma ka hoʻohui ʻana i ka 3% - 4% photoinitiato.E ʻoluʻolu e mālama i kahi maloʻo a maloʻo paha, a pale i ka lā a me ka wela; ʻAʻole ʻoi aku ka mahana o ka mālama ʻana ma mua o 40 ºC, nā kūlana mālama ma lalo o nā kūlana maʻamau no ka liʻiliʻi o 6 mahina.

Hoʻomaka ʻia me ka polyethylene glycol (PEG, MW 1000) ε- Caprolactone（ ε- Ua hoʻomākaukau ʻia ka ʻāpana palupalu o ka polyether ester block copolymer diol (pCEC) ma ka wehe ʻana o ke apo, hoʻopili ʻia me ka diisocyanate (toluene diisocyanate a i ʻole diphenylmethane diisocyanate, a laila hydroxylateethyl methac. Ua ho'ōla 'ia no ka loa'a 'ana o ka polyether ester polyurethane acrylate material (PUA) Ua 'ike 'ia ka haku mele 'ana a me ke 'ano o PUA. ʻoi aku ka maikaʻi o ka hydrophilicity a me ka hana degradation ma mua o ka PUA Pcec2000-tdi.He 65.24% ke kiʻekiʻe o ka wai i loko o 72 hola a hiki ke hoʻohaʻahaʻa ʻia i loko o ka hopena enzyme i loko o 11 mau pule He hiki ke hoʻohana ʻia kēia ʻano mea PUA i nā mea hana ʻenehana.
