Kugirango tunonosore ubukana hamwe na elastike yo hejuru ya sima ya sima gakondo muri minisiteri, mubisanzwe birakenewe kongeramo ifu ya redxersible latx nkinyongeramusaruro, ishobora guha sima ya sima guhinduka neza nimbaraga zikomeye.Kurwanya no gutinza ibisekuruza bya sima ya sima, kubera ko polymer na minisiteri bigize imiyoboro ihuza imiyoboro, firime ikomeza ya polymer ikorwa mu byobo, bishimangira isano iri hagati ya agregate kandi igahagarika ibice biri mu byobo bya minisiteri, bityo bigahinduka mortar nyuma yo gukomera yazamuye imikorere cyane kuruta sima.
Ifu ya latex ikorwa nubushyuhe bwinshi, umuvuduko mwinshi, kumisha spray hamwe na homopolymerisation hamwe na micropowders zitandukanye zishimangira imbaraga, zishobora kuzamura cyane ubushobozi bwo guhuza imbaraga nimbaraga za minisiteri, kandi ikagira imikorere myiza yubwubatsi bwo kurwanya kugwa, kubika amazi no kubyimba , kurwanya amazi no kurwanya ubukonje, Kurwanya ubushyuhe bwiza cyane, ibintu byoroshye, byoroshye gukoresha.Ifu ya Xindadi latex ifite ubwuzuzanye buhebuje na sima, irashobora gushonga burundu muri sima ishingiye ku byumye bivanze na sima, ntibigabanya imbaraga za sima nyuma yo gukira, ntibigumya gusa gufatana neza, gukora firime no guhinduka, ariko kandi bifite ibyiza Kurwanya ikirere, gutekana, guhuza ibikorwa no guhangana.Nyuma yo gukama, irashobora gukumira neza isuri yumuyaga wa acide kurukuta, kandi ntabwo byoroshye guhindagurika no gutanga nyuma yo gutose.Irashobora kongera imbaraga kubicuruzwa.Ongeramo ifu ya redxersible latex yifu ya putty na mortar birashobora kongera imbaraga, kandi nibyiza cyane kunoza ubukana.Ifite imikorere idasanzwe y’amazi, imbaraga nziza zo guhuza, irashobora kandi kongera ubworoherane bwa minisiteri kandi ikagira igihe kirekire cyo gufungura, kandi igaha minisiteri imbaraga zo kurwanya alkali nziza, kandi irashobora kunoza kwizirika / gufatira hamwe no guhangana na minisiteri.Usibye imbaraga, kwambara birwanya kandi byubaka, bifite imbaraga zihindagurika muri minisiteri irwanya anti-cracking.
Mu buryo bw'igitekerezo, ifu ya latex ifite ubushyuhe bwikirahure munsi ya 5 ° C iroroshye guhinduka kandi ikoreshwa cyane mumashanyarazi yo hanze, kandi ifu ya latex hamwe nubushyuhe bwikirahure hejuru ya 10 ° C ikoreshwa cyane mubifata no kwishyira hejuru. minisiteri.
Ukurikije ibice bya minisiteri, imikorere ya minisiteri nayo izagira ingaruka kumihindagurikire yongeweho yifu ya redispersible latex ifu: umubare wongeyeho ifu ya redxersible latx iri munsi ya 1%, ifite ingaruka runaka ku iyubakwa no gufatira kuri minisiteri;Kwiyongera k'ifu ya redxersible latex ni 1, 2.0%, itezimbere imbaraga, kurwanya amazi no guhinduka kwa minisiteri;hiyongereyeho ifu ya redispersible latex ni 2.0, 5%, ikora firime ya firime ya firime muri minisiteri.Munsi yikirere nintera zitandukanye, imbaraga nubworoherane bwa minisiteri biragaragara ko byateye imbere.
Ku bijyanye n’ifu ya latx nyinshi, icyiciro cya polymer muri minisiteri yakize kirenze buhoro buhoro icyiciro cyibicuruzwa biva mu mahanga, kandi minisiteri ihinduka ihinduka ryiza kandi ihinduka umubiri wa elastique, mugihe ibicuruzwa biva muri sima bihinduka "uwuzuza" ”.Filime yakozwe na powder isubirwamo ya latx ikwirakwizwa kuri interineti igira urundi ruhare rwingenzi, ni ukuvuga mu rwego rwo kurushaho kwizirika ku bikoresho byahujwe, bikwiranye n’imiterere igoye-gukomera, nko kwinjiza amazi make cyane cyangwa Non- Ubuso bwinjiza (nkibintu byoroshye bya beto na sima hejuru yububiko, amasahani yicyuma, amatafari ya homogeneous, amatafari ya vitrified, nibindi) hamwe nubutaka bwibinyabuzima (nkibibaho bya EPS, plastike, nibindi) nibyingenzi.Kuberako guhuza ibikoresho na meta-mashini bifata bigerwaho hifashishijwe ihame ryo gushiramo imashini, ni ukuvuga, hydraulic slurry yinjira mu cyuho cyibindi bikoresho, igenda ikomera buhoro buhoro, amaherezo ifata minisiteri nkurufunguzo rwinjijwe mu gifunga .Ku buso bwibikoresho, kubuso bwavuzwe haruguru bugoye-guhuza, kubera kutabasha kwinjira neza mubikoresho kugirango habeho imashini nziza, minisiteri ifite gusa ibinyabuzima bidafatika ntabwo ihujwe neza nayo, na electron kwitegereza microscope nabyo ni byiza cyane.Birabigaragaza.Uburyo bwo guhuza polymers buratandukanye.Polimeri ihuza ubuso bwibindi bikoresho nimbaraga za intermolecular, zidashingiye ku buso bwubuso (birumvikana, ubuso butagaragara hamwe nubuso bwiyongera bwongerera imbaraga imbaraga), ibyo bikaba bigaragara cyane mubijyanye na substrate organic, na kwitegereza microscopes ya electron nayo irerekana imbaraga zayo zifata.
Ifu ya latex ihindura ubudahangarwa 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 tile ifata neza, igabanya modulus ya elastique, ikurura imbaraga zo guhindura amashyuza ku rugero runini, kandi ikagira imbaraga zo kurwanya amazi mugice cyanyuma, kandi ubushyuhe bwa buffer hamwe no guhindura ibintu ntibihuye. .Guhindura no gukomera kwifu ya latex irashobora kugenzurwa ukurikije ubushyuhe bwikirahure.Niba ubushyuhe bwikirahure buri munsi ya dogere 0, biroroshye guhinduka.Ni ubuhe bwoko bw'ifu ya latex ikenewe muri minisiteri igenwa muri rusange ukurikije imikorere y'ibicuruzwa.Amatafari ya tile akeneye gukoresha ifu ya latex hamwe no gufatana neza.
