Ifu ya redispersible latex ni ibintu bisanzwe bikoreshwa mu gutondeka kama, bishobora kongera gutatanywa neza mumazi kugirango bibe emulisiyo nyuma yo guhura namazi. Ongeramo ifu ya redxersible latex irashobora kunoza imikorere yo gufata amazi ya sima ivanze ya sima nshya, hamwe nuburyo bwo guhuza, guhinduka, kudahinduka no kurwanya ruswa ya sima ikomeye. Ifu ya latex ihindura ubudahwema nubunyerera bwa sisitemu muburyo bwo kuvanga amazi, kandi guhuriza hamwe kunozwa wongeyeho ifu ya latex. Nyuma yo kumisha, itanga ubuso bworoshye kandi bwuzuye hejuru yububasha hamwe, kandi bugateza imbere intera yumucanga, amabuye na pore. , ikungahaye kuri firime kuri interineti, ituma ibintu byoroha, bigabanya modulus ya elastike, ikurura imbaraga zo guhindura amashyuza ku rugero runini, kandi ikagira imbaraga zo guhangana n’amazi mu cyiciro cyakurikiyeho, kandi ubushyuhe bwa buffer no guhindura ibintu ntibihuye.
Gukora firime ikomeza ya polymer ningirakamaro cyane mumikorere ya polymer-yahinduwe na sima. Mugihe cyo gushiraho no gukomera kwa sima ya sima, hazavamo imyenge myinshi imbere, ihinduka ibice byintege nke za sima. Ifu ya redispersible latex yongewemo, ifu ya latex izahita ikwirakwira muri emulsiyo iyo ihuye namazi, hanyuma igateranira ahantu hakungahaye kumazi (ni ukuvuga mu cyuho). Mugihe isima ya sima igenda ikomera, kugenda kwa polymer bigenda bigabanuka, kandi impagarara hagati yamazi nikirere ibahatira guhuza buhoro buhoro. Iyo uduce twa polymer duhuye nundi, urusobe rwamazi rwuka runyuze muri capillaries, hanyuma polymer ikora firime ikomeza ikikije umwobo, igashimangira utwo duce dufite intege nke. Muri iki gihe, firime ya polymer ntishobora kugira uruhare rwa hydrophobique gusa, ariko kandi ntishobora no guhagarika capillary, kugirango ibikoresho bigire hydrophobicity kandi byinjira mu kirere.
Isima ya sima idafite polymer ihujwe cyane hamwe. Ibinyuranye na byo, polymer yahinduwe na sima ya marimari ituma minisiteri yose ihuza cyane kubera ko hari firime ya polymer, bityo ikabona ibikoresho byiza byubukanishi hamwe nigitsina kirwanya ikirere. Ifu ya latex yahinduwe na sima ya sima, ifu ya latex izongera ubukana bwa paste ya sima, ariko igabanye ubukana bwakarere ka inzibacyuho yimbere hagati ya sima hamwe na hamwe, bikavamo ubwinshi muri minisiteri idahinduka. Ifu ya latex imaze gukorwa muri firime, irashobora guhagarika neza imyenge iri muri minisiteri, bigatuma imiterere yakarere kinjira hagati yimbere hagati ya sima hamwe nigiteranyo cyinshi, kandi imbaraga zo kwihanganira ifu ya latx yahinduwe. , kandi ubushobozi bwo kurwanya isuri yibitangazamakuru byangiza byongerewe. Ifite ingaruka nziza mugutezimbere uburebure bwa minisiteri.
