Nigute fenol formaldehyde resin ikorwa？

Bakelite ni resinike.Fenolike resin (PF) ni ubwoko bwibicuruzwa bya pulasitiki.Ibikoresho fatizo byumusemburo wa fenolike ni fenol na aldehyde, kandi fenol na formaldehyde bikoreshwa cyane.Bahinduwe na polymerisiyasi ya reaction ya catisale ya acide, base nizindi catalizator.Hariho ubwoko bubiri bwibikorwa byinganda: inzira yumye nuburyo butose.

Mubikorwa bya catalizator zitandukanye, fenol na aldehyde zirashobora kubyara ubwoko bubiri bwibisigarira bya fenolike: kimwe ni resinoplastique fenolike, ikindi ni thermosetting fenolike.Iyambere irashobora gukira muburyo bwo guhagarika wongeyeho imiti ikiza no gushyushya, mugihe iyanyuma irashobora gukira muburyo bwo guhagarika gushyushya utongeyeho imiti ikiza.

Thermoplastique fenolike resin hamwe na resmosetting ya fenolike irashobora gukoreshwa gusa binyuze mumurongo wo guhanahana amakuru ukiza.Igikorwa cyo gukiza nugukomeza imiterere ya polycondensation no gukora ibicuruzwa.Iyi nzira iratandukanye no gushonga no gukiza muri rusange thermoplastique.Byombi kumubiri nubumashini ntibisubirwaho.

Fenolike resin irashobora guterwa inshinge muburyo busa na thermoplastique.PF yo kubumba inshingebisaba gutembera neza, birashobora kubumbabumbwa munsi yumuvuduko ukabije watewe, ubushyuhe bukabije bwumuriro, umuvuduko ukomera, urumuri rwiza rwibice bya plastike, kumeneka byoroshye, kandi nta mwanda uhumanye.Ariko, kubumba inshinge nabyo bifite ibibi.Kurugero, gushonga bigarukira kubwoko bwuzuza, ntabwo rero bikwiye gukoresha insimburangingo nyinshi kugirango ube ibice bya plastiki.Umubare munini wamarembo numuyoboro ntibishobora gukoreshwa nyuma yo gukira, kandi birashobora gutabwa gusa.

Mu ijambo rimwe, resinoplastique ya fenolike irashobora gukorwa n imashini isanzwe itera inshinge, ariko uburyo bwo kubikora buragenzurwa cyane.Ubushuhe bwa Thermosetting fenolike bugomba gukorwa n imashini idasanzwe yo gutera inshinge ya fenolike, kandi ifumbire nayo ifata imiterere yihariye.

Irakoreshwa cyane muriibikoresho by'amashanyarazi, amasogisi, abafite itara,sandwich imashini, n'ibindi;Ariko, imikorere yacyo idahwitse hamwe ningutu itoroshye irashobora kugabanya iterambere ryayo.Hamwe no kugaragara kwizindi plastiki, ibicuruzwa bya bakelite ntibyoroshye kubona ubu.Nubwo ibicuruzwa bya bakelite bigomba gushyukwa kugirango bibumbwe, igihe cyo gutunganya ni kirekire kuruta icya plastiki zisanzwe, kandi kwambara ibumba ni binini, bisaba ibisabwa cyane ku byuma, ariko kubera umwanya wacyo mwiza mu giciro cy’ibikoresho fatizo, ni iracyasimbuza ibice byinshi bya plastiki.
