Ifu ya kole ya Urea Formaldehyde, yiteguye koherezwa ~

Ibisobanuro by'igicuruzwa

Resin ya Urea-formaldehyde (UF), izwi kandi nka resin ya urea-formaldehyde, ni polycondensation ya urea na formaldehyde binyuze mu gikorwa cya catalyst (alkaline cyangwa aside catalyst) kugira ngo habeho resin ya mbere ya urea-formaldehyde, hanyuma igakora igice cya nyuma kidashonga kandi kidashonga munsi y'igikorwa cy'umuti cyangwa inyongera. Resin yo gushyiraho thermosetting. Resin ya urea-formaldehyde yakuweho ifite ibara ryoroheje kurusha resin ya phenolic, irabagirana, irwanya aside nke na alkali nke, ifite ubushobozi bwiza bwo gukingira, irahangana neza no kwangirika, kandi ihendutse. Ni ubwoko bukoreshwa cyane mu ma-kole, cyane cyane mu gukora ama-panels atandukanye y'ubukorano mu nganda zitunganya imbaho, resin ya urea-formaldehyde n'ibicuruzwa byayo byahinduwe bigira hafi 90% by'ikoreshwa ryose rya kole. Ariko, resin ya urea-formaldehyde yoroshye kubora iyo ihuye na aside zikomeye na alkali. Ifite ubushobozi buke bwo guhangana n'ikirere, ubukana buke bw'ibanze, gucika cyane, kudakomera, kudashira amazi, no gusaza byoroshye. Ama-panels akozwe na resin ya urea-formaldehyde arekura formaldehyde mu gihe cyo gukora no gukoresha. Ikibazo ni uko igomba guhinduka.

Porogaramu

Ishobora gukoreshwa mu bintu bidasaba amazi menshi kandi bidasaba imiterere ya dielectric, nk'imirongo y'amashanyarazi, switch, imigozi y'imashini, udusanduku tw'ibikoresho, udupfundikizo, ibintu bikenerwa buri munsi, imitako, amatafari ya mahjong, umupfundikizo w'ubwiherero, kandi ishobora no gukoreshwa mu gukora ibikoresho bimwe na bimwe byo ku meza.

Resine ya Urea-formaldehyde ni yo ikoreshwa cyane mu gukora ibibabi bitandukanye by’ubukorano mu nganda zitunganya imbaho, resine ya urea-formaldehyde n’ibicuruzwa byayo byahinduwe bigira hafi 90% by’ibikoreshwa byose bya kole.
