Ni gute wamenya ubwiza bw'ifu ya polymer ishobora gusubirwamo?

mbere na mbere. Banza usobanukirwe icyo ari cyoifu ya polimeri ishobora kongera gushonga.

Ifu ya polymer ishobora gutatanywa ni polymeri z'ifu zikozwe muri polymeri zikozwe mu buryo bukwiye bwo kumisha (no guhitamo inyongeramusaruro zikwiye). Ifu ya polymeri yumye ihinduka emulsion iyo ihuye n'amazi, kandi ishobora kongera gukurwamo amazi mu gihe cyo gufunga no gukomera kwa mortilage, ku buryo uduce twa polymeri dukora imiterere y'umubiri wa polymeri muri mortilage, isa n'igikorwa cya polymeri zikozwemo, zishobora kunoza mortilage ya sima. Ingaruka z'imibonano mpuzabitsina. Mortilage yahinduwe ya emulsion y'ifu yumye yitwa mortilage yumye (izwi kandi nka mortilage yumye, mortilage yumye). Kubera ko ifu yumye idakeneye gusuzuma uburyo bwo gushushanya emulsion no kugumana imbaraga nk'imyunyungugu ya polymeri, ingano nto y'imyunyungugu ishobora gutuma mortilage igera ku miterere yifuza, kandi ifite ibyiza byo koroshya gupakira, kubika, gutwara no gutanga kurusha emulsion, antikonjeze no kudakura kw'ibihumyo, Ikibazo cya bagiteri nzima, n'akamaro ko ishobora gukorwamo ikintu kimwe gifite ipaki yateguwe nka sima n'umucanga, kandi ishobora gukoreshwa nyuma yo kongeramo amazi.

Mu gihe ushyiramo, vanga kandi upakire umucanga, sima, ifu yumye ya emulsion n'ibindi bikoresho by'inyongera mbere y'igihe, kandi ugomba kongeramo amazi runaka mu gihe cyo kubaka aho hantu kugira ngo ukore sima y'ifu yumye ifite imikorere myiza. Ishingiro ry'ikorwa ry'ifu yumye ya emulsion ni uko uduce twa polymer nyuma yo kongera gushonga kw'ifu ya latex tugaragaza ingano y'uduce cyangwa ingano y'uduce isa n'iya polymer ya emulsion ya mbere. Ingano runaka ya colloid irinda nka polyvinyl alcohol igomba kongerwa muri emulsion, kugira ngo ifu ya latex ishobore kongera gukwirakwizwa muri emulsion iyo ihuye n'amazi. Iyo ifu ya latex ikwirakwizwa neza ni bwo igera ku ngaruka nziza. . Ifu ya polymer ikwirakwizwa akenshi iba ifu yera. Ibikubiye muri yo birimo:

Resine ya polimeri: Iherereye mu gice cy'ibanze cy'uduce tw'ifu ya rubber, kandi ni na yo gice cy'ingenzi cy'ifu ya polimeri ishobora kongera gushonga.

Inyongeramusaruro (imbere): hamwe na resin, bigira uruhare mu guhindura resin. Inyongeramusaruro (inyuma): Harimo kongeramo ibindi bikoresho kugira ngo byongere imikorere y'ifu ya polymer ikwirakwira.

Colloid irinda: urwego rw'ibikoresho bikunda amazi bipfunyitse ku buso bw'uduce tw'ifu ya latex ishobora gusubirwamo, colloid irinda ifu nyinshi ya latex ishobora gusubirwamo ni alukolo ya polyvinyl.

Umuti urinda guteka: icyuma gito cyuzuza amabuye y'agaciro, gikoreshwa cyane cyane mu gukumira ifu ya rubber guteka mu gihe cyo kubika no gutwara no koroshya urujya n'uruza rw'ifu ya rubber (iva mu mifuka y'impapuro cyangwa mu mato.)

Ni gute wamenya ubwiza bw'ifu ya latex ishobora kongera gushonga?

Uburyo bwa 1, uburyo bw'ivu

Fata ingano runaka y'ifu ya latex ishobora kongera gushonga, uyishyire mu gikoresho cy'icyuma umaze gupima, uyishyushye kugeza kuri dogere 500, umaze gushyushya ku bushyuhe bwinshi bwa dogere 500, uyikonjeshe kugeza ku bushyuhe bw'icyumba, hanyuma wongere uyipime. Uburemere bworoheje kandi bwiza.

Uburyo bwa kabiri, uburyo bwo gusenya

Fata ingano runaka y'ifu ya latex ishobora gukurwamo amazi hanyuma uyishongeshe mu mazi akubye inshuro 5, uvange neza hanyuma uyireke ihagarare iminota 5 mbere yo kuyireba. Muri rusange, uko ibice bike byinjira mu gice cyo hasi, niko ifu ya polymer ishobora gukurwamo amazi irushaho kuba nziza. Ubu buryo bworoshye kandi bworoshye kubukora.

Uburyo bwa gatatu, uburyo bwo gukora filime

Fata ifu ya latex ishobora gukurwamo ubuziranenge runaka, uyishongeshe inshuro ebyiri z'amazi, uyivange neza, uyireke ihagarare iminota 2, wongere uyivange, usuke umuti ku kirahuri gisukuye, hanyuma ushyire ikirahuri ahantu hafite umwuka mwiza. Kuramo iyo cyumye neza. Reba agapira ka polymer kakuweho. Gafite urumuri rwinshi kandi ni keza. Hanyuma ukuremo ku rugero, gafite ubuziranenge bwiza kandi ni keza. Agapira kaciwemo uduce, kajugunywa mu mazi, hanyuma kakaboneka nyuma y'umunsi umwe, ubuziranenge bwa filime bwashongeshejwe buhoro mu mazi. Ubu buryo ni bwiza kurushaho
