Gucapura

Gucapa ibinini ni kimwe mubikoreshwa cyane mubikorwa byo gucapa.Mu gucapa, ibikoresho bibiri byingenzi byakoreshejwe ni kole hamwe na paste.Kandi kubera ko ubudahwema buzagabanuka munsi yingufu zo kogosha cyane, umubyimba ukoreshwa kugirango wongere ibikoresho byo gucapa, kandi icapiro rirakenewe muriki gihe.

Igikorwa nyamukuru cyo gucapa ibyimbye ni ugutanga imiterere myiza ya rheologiya, kwimura kole cyangwa ibara ryamabara kuri ecran yo gucapa no gucapisha roller kumyenda, kugirango irangi na fibre bihurijwe hamwe kugirango harebwe neza uburyo bwo gucapa neza.Igishushanyo kirasobanutse kandi ibara rirasa kandi ni kimwe;iyo irangi ryakosowe, ibicuruzwa bya reaction nibisigara bikurwaho muburyo bworoshye, bigatuma umwenda wumva woroshye.Ibi birerekana ko gucapa ibinini bigira uruhare runini mubikorwa byo gucapa.

Gukwirakwiza icapiro ryimyororokere ni guhuza-guhuza polymer compozisiyo ya emulsion.Nyuma yo kuyungurura no kutabogama hamwe namazi, ibice bya polymer bishingiye kumazi bizaguka vuba.Muri iki gihe, ibicuruzwa byacapwe bizasobanuka neza kandi bifatanye.Gukwirakwiza icapiro ryimyororokere irashobora kongera neza ubwoya bwogosha buke bwa sisitemu yo gucapa kandi bigatuma sisitemu yo gucapa igira pseudoplastique.Irangi ryirangi ryateguwe hamwe no gukwirakwiza icapiro ryinshi nkuko umubyimba munini ufite umusaruro mwinshi hamwe nuburyo bwa gel.Iyi miterere ntabwo igaragara kugeza igihe imbaraga zo gukata zabuze.Kubwibyo, gusohora icapiro ryimyororokere irakwiriye mugutegura icapiro hamwe ningero eshatu zingana.

Gucapa ibyimbye bifite amateka maremare yiterambere.Ingano yakoreshejwe kera cyane yari krahisi cyangwa yahinduwe.Ubu bwoko bwo kubyimba bwitwa umubyimba karemano, ariko ubu bwoko bwo gucapa bugira igiciro kinini, uburebure bwamabara make, kutagaragara neza, gukaraba nabi, hamwe nimyenda idashimishije.Kugeza ubu, ubu bwoko bwo kubyimba bwagiye buvaho.Mu myaka ya za 1950, ni bwo abantu batangije igipimo cy’igihugu, cyatumaga tekinoroji yo gucapa ikoreshwa cyane.Ukoresheje kerosene namazi nkibikoresho fatizo, bigenda byihuta byihuta byiganjemo ibikorwa bya emulisiferi kugirango bibe byimbitse ya leta.Kuberako umubyimba urimo kerosene hejuru ya 50 # kandi ubwinshi ni bwinshi, bizatera umwanda mwinshi mwikirere kandi bifite ibyago byo guturika.Mubyongeyeho, guhuzagurika kwa paste ntago byoroshye guhinduka, kandi impumuro ya kerosene izaguma kumyenda nyuma yo gucapa.Abantu rero ntibanyurwa niyi icapiro.Mu myaka ya za 70, abantu batangiye kwiteza imbere no kubyara intungamubiri.Kugaragara kwa sintetike yububiko byateje imbere cyane iterambere ryimyandikire kandi bizamura tekinoroji yo gucapa kurwego rushya.Ikemura ibibazo byangiza ibidukikije nibibazo byumutekano.Byongeye kandi, intungamubiri ya syntetique ifite ibyiza byo kubyimba neza, gutwara no kubika byoroshye, gutegura byoroshye, urucacagu rusobanutse, ibara ryiza nibindi bisa.

Turi Gutatanya Icapiro rya Thickener.Niba ushimishijwe nibicuruzwa byacu, nyamuneka twandikire.
