Polyether polyurethane acrylate ee dahaarka caagga ah

Koodhka Alaabta: ZC6202

Product ZC6202 waa wax soo saarka sumadda ee shirkadda.Magaceeda kiimikada waa polyether polyurethane acrylate.Waa dareere hufan oo aan midab lahayn ama huruud ah oo leh dabacsanaan iyo ku dhegganaan wanaagsan.Waxaa inta badan loo isticmaalaa waraaqaha, dahaarka caaga ah iyo alwaax ku dheggan.Udgoon polyurethane acrylate

Ku dar polyeter (polyester) diol iyo polymerization inhibitor afar galaas deked ah oo ku qalabaysan mishiinka walaaqaya, heerkulbeegga iyo tuubada kondenserka, si siman u walaaq, ka dibna ku dar TDI, kor u qaad heerkulka 70-80 ℃ ee falcelinta saacadaha 1.5, ogow qiimaha NCO, ka dibna ku dar hydroxyethyl acrylate (hydroxypropyl acrylate), ku dar kicinta, sii wad falcelinta saacadaha 3, oo ogow in qiimaha NCO uu la mid yahay 0. Viscosity of polyurethane acrylate aromatic waxaa lagu qiyaasay muunad, iyo waxqabadka caraf udgoon polyurethane acrylate ayaa la tijaabiyay. adoo ku daraya 3% - 4% photoinitiato. Fadlan qabooji ama meel engegan, iskana ilaali qoraxda iyo kulaylka; heerkulka kaydinta kama badna 40ºC, xaaladaha kaydinta ee xaaladaha caadiga ah ugu yaraan 6 bilood.

Waxaa lagu bilaabay polyetylen glycol (PEG, MW 1000) ε- Caprolactone ( ε- Qaybta jilicsan ee polyether ester block copolymer diol (pCEC) waxaa lagu diyaariyey furitaanka giraanta, oo lagu falceliyay diisocyanate (toluene diisocyanate ama diphenylmethane diisocylatethylate, ka dibna mediphenylmethane diisocyanate) iyo la daaweeyay si loo helo polyether ester polyurethane acrylate material (PUA) Halabuurka iyo qaab dhismeedka PUA ayaa lagu sifeeyay Natiijooyinku waxay muujinayaan in kordhinta qaybta PCL ay hagaajin karto crystallinity ee walxaha PUA, laakiin waxay yaraynaysaa nuugista biyaha iyo heerka xaalufka Heerka enzymatic hydrolysis ee PUA wuxuu ahaa mid sare. Marka loo eego tan PUA Pcec2000-tdi walaxda waxay leedahay wax-qabad biyo-bax aad u fiican iyo hoos u dhac.Nuugista biyuhu waxay u badan tahay 65.24% saacadaha 72 waxayna si buuxda u hoos u dhigi karaan xalalka enzyme gudaha 11 usbuuca Maaddada PUA ee noocan oo kale ah waxay awood u leedahay in loo isticmaalo qalabka injineernimada unugyada.
