Isubirwamo rya latx ifu nkibyingenzi byingenzi byumye-bivanze na minisiteri

Ifu ya Redispersible latex ni ifu ikwirakwizwa ikozwe muri polymer emulisiyo yahinduwe mukumisha. Ifite ubwikorezi buhebuje kandi irashobora kongera gusunikwa mumashanyarazi ya polymer ihamye nyuma yo kurekura amazi. Ubuhanga bwa chimie burasa neza na lisansi yumwimerere. Kubwibyo, birashoboka gukora ubuziranenge bwumye bwumye, bityo bikazamura imikorere ya sima.

Redispersible latex ifu ningirakamaro yingirakamaro ya minisiteri. Irashobora kunoza imikorere ya minisiteri, kongera imbaraga zo gukomeretsa za sima ya sima, kunoza imbaraga zihuza za sima na sima zitandukanye, no kunoza imbaraga za sima. Kwiyoroshya no guhindagurika, imbaraga zikaze, imbaraga zo kwikuramo, kurwanya abrasion, guhindagurika, gusiganwa kwa adhesion hamwe nubushobozi bwo gufunga amazi, no kubaka. Byongeye kandi, ifu ya latx isanzwe hamwe no kurwanya amazi irashobora gutuma marima ya sima igira ubukana bwiza.

Kunoza ubumwe bwa sima ya minisiteri mubwubatsi. Nyuma yo kuvangwa na sima ya sima ivanze na naturike ya latx isanzwe ikwirakwizwa, amazi azagenda agabanuka buhoro buhoro hamwe no gusya no kwinjiza amazi kubishingwe, gukoresha reaction ikomeye, hamwe no guhumeka umwuka. , ibice bigenda byegereza buhoro buhoro, impapuro zigenda zijimye, kandi zigenda zihuzwa hamwe. Hanyuma, polymer irekuwe. Inzira yose yo gukuraho polymer igabanijwemo ibice bitatu. Muri emulsiyo yumwimerere yumwimerere, polymer ibice biri muburyo bwimikorere ya Brown. Himura mu bwisanzure, hamwe no guhindagurika kwamazi, urujya n'uruza rw'ibice rusanzwe rushobora gukumirwa cyane, hejuru yubushyuhe bwamazi na gaze bibatera gutondekanya buhoro buhoro, icyiciro cya kabiri, mugihe ibice bitangiye gukoraho, umuyoboro Amazi afite ishusho ihindagurika binyuze muri capillaries, kandi imbaraga zifasha cyane zirekurwa hejuru yutwo duce duto zitera ihinduka ryimiterere ya latx naturel kugirango ihuze hamwe, kandi amazi asigaye yuzuza imyenge, kandi birashoboka ko byakozwe. . Icya gatatu Intambwe yanyuma nugukora ikwirakwizwa rya molekile ya polymer (rimwe na rimwe bita kwifata) ikora firime nyayo ikomeza mugihe cyo gusenya.
