Gucapa ibyimbye: Nubwoko bwibyimbye bikunze gukoreshwa mubikorwa byo gucapa.Mu gucapa, ibikoresho bibiri byingenzi, kole na paste yamabara, birakoreshwa.Kandi kubera ko munsi yimisatsi miremire, guhuzagurika bizagabanuka, birakenewe rero gukoresha umubyimba kugirango wongere ibintu byacapwe, hanyuma icapiro rikoreshwa.
Gucapa umubyimba munini wubushinwa nugutanga imiterere myiza ya rheologiya, kwimura kole cyangwa ibara ryamabara kuri ecran yo gucapa no gucapisha uruzitiro kumyenda, guhuza irangi na fibre, no kwemeza urutonde rwuburyo bwo gucapa.zitandukanye.Igishushanyo kirasobanutse, ibara rirasa kandi ni kimwe;iyo irangi ryakosowe, ibicuruzwa byerekana nibisigara bikurwaho byoroshye mugikorwa cyo hasi, bigatuma umwenda wumva woroshye.Birashobora kugaragara ko icapiro ryimbitse rifite uruhare runini mubikorwa byo gucapa.
Amateka y'Iterambere:
Gucapa ibyimbye bifite amateka maremare yiterambere.Ibishishwa byakoreshejwe kera cyane byari ibinyamisogwe cyangwa byahinduwe.Uku kubyimba kwitwa umubyimba karemano, ariko uku gucapa kubyimbye bifite igiciro kinini cyo gukoresha, uburebure bwamabara make, kutagaragara neza, hamwe no kwihanganira Kwihuta gukaraba nabyo ni bibi, kandi imyenda yigitambara ntabwo ishimishije.Kugeza ubu, ubu bwoko bwibibyibushye bwakuweho buhoro buhoro.Mu myaka ya za 1950 ni bwo abantu batangije A-leta ya pulp, ituma ikoranabuhanga ryo gucapa rikoreshwa cyane.Umubyimba wa leta wimbaraga ukorwa na emulisation yihuse ya kerosene namazi munsi ya emulifier.Kuberako ubu mubyimbye burimo 50 # kerosene zirenga 50, kandi ninshi zikoreshwa, zitera umwanda mwinshi mukirere kandi ibyago byo guturika.Mubyongeyeho, guhuzagurika kwa paste ntago byoroshye guhinduka, kandi impumuro ya kerosene izaguma kumyenda nyuma yo gucapa.Abantu rero ntibaranyurwa nubu bwoko bwo gucapa.
Gucapa
Mu myaka ya za 70, abantu batangiye kwiteza imbere no kubyara intungamubiri.Kuza kwa sintetike yibyimbye byateje imbere cyane iterambere ryibicuruzwa kandi bizamura tekinoroji yo gucapa kurwego rushya.Ikemura ibibazo byangiza ibidukikije n'umutekano.Byongeye kandi, umubyimba wa sintetike ufite ibyiza byo kubyimba neza, gutwara no kubika byoroshye, gutegura byoroshye, urucacagu rusobanutse, ibara ryiza nibindi.
Ibyiciro byo gucapa ibyimbye:
Hariho ubwoko bwinshi bwo gucapa ibyimbye, kuri ubu bigabanijwemo ibyiciro bibiri byingenzi: nonionic na anionic.Ibibyibushye bya Nonionic ahanini ni inkomoko ya polyethylene glycol ether.Ibibyimba nkibi bigomba kugira intera nini, ariko ingaruka zo kubyimba ni mbi, umubare wongeyeho ni munini, kandi umubare wa kerosene uracyakenewe.Kubwibyo, ibi nabyo bigabanya iterambere ryayo.
Umubyimba wa anionic ni polymer electrolyte ivanze, ikaba copolymer hamwe no guhuza urumuri.Irangwa nubwiza buke, ingaruka nziza yo kubyimba, gutuza neza, kwiyongera gake, imvugo nziza, ningaruka zo gucapa.byiza.Ikigaragara cyane ni polyacrylic compound.Kugeza ubu, aside polyacrylic ikunze kugaragara cyane ni anionic polymer electrolyte.Ikoresha uburyo bwa emulion polymerisation kugirango polymerize neza monomers zishonga mumazi mubicuruzwa byamata.Nibyiza gukora paste hamwe no gutuza kwa paste yumwimerere hamwe na paste yamabara.Umwenda wacapwe woroshye gukoraho kandi urashobora kubikwa igihe kirekire.Nibyo dukunze kuvuga kubyerekeranye na PTF.
