Urea Formaldehyde Ifu ya kole ， Yiteguye koherezwa ~

Ibisobanuro ku bicuruzwa
Urea-formaldehyde resin (UF), izwi kandi nka urea-formaldehyde resin, ni polycondensation ya urea na formaldehyde ikozwe na catalizator (alkaline cyangwa acide catisale) kugirango ikore resine yambere ya urea-formaldehyde, hanyuma ikore idashobora gushonga hanyuma infusible icyiciro cyanyuma munsi yigikorwa cyumuti ukiza cyangwa inyongera. Thermosetting resin. Amashanyarazi ya urea-formaldehyde yoroheje yoroheje kurusha amabara ya fenolike, yoroheje, irwanya acide nkeya na alkali idakomeye, ifite imitekerereze myiza, irwanya kwambara neza, kandi ihendutse. Nubwoko bukoreshwa cyane mubifata, cyane cyane Mubikorwa byo gukora imbaho ​​zitandukanye zubukorikori mu nganda zitunganya ibiti, resine ya urea-formaldehyde hamwe nibicuruzwa byahinduwe bingana na 90% byimikoreshereze yose. Nyamara, urea-formaldehyde resin iroroshye kubora iyo ihuye na acide ikomeye na alkalis. Ifite imiterere mibi yikirere, ubukonje bwambere bwambere, kugabanuka kwinshi, ubwinshi, kurwanya amazi, no gusaza byoroshye. Ikibaho cyakozwe na urea-formaldehyde resin irekura formaldehyde mugihe cyo gukora no gukoresha. ikibazo, igomba rero guhinduka.

Gusaba
Irashobora gukoreshwa mubicuruzwa bidasaba kurwanya amazi menshi hamwe nubushobozi bwa dielectric, nkumurongo wamashanyarazi, guhinduranya, imashini zikoresha imashini, ibikoresho, ibikoresho, ibikenerwa bya buri munsi, imitako, amabati ya mahjong, umupfundikizo wubwiherero, kandi birashobora no gukoreshwa muri gukora ibikoresho bimwe byo kumeza.

Urea-formaldehyde resin nubwoko bukoreshwa cyane. By'umwihariko mu gukora imbaho ​​zitandukanye zakozwe mu nganda zitunganya ibiti, urea-formaldehyde resin n'ibicuruzwa byahinduwe bingana na 90% by'ibikoreshwa byose.
