Ni ubuhe bwoko butandukanye bwa minisiteri yumye? Gukoresha ifu ya redxersible latex

Ifu yumye yumye bivuga ibintu bya granular cyangwa ifu byakozwe no kuvanga umubiri, ibikoresho bya sima organique, hamwe ninyongeramusaruro zumye kandi zerekanwe muburyo runaka. Nibihe byongeweho bisanzwe byongerwaho ifu yumye? Ifu yumye yumye muri rusange ikoresha sima ya Portland nkibikoresho bya sima, kandi umubare wibikoresho bya sima mubusanzwe bingana na 20% kugeza 40% byifu yumye; Igiteranyo cyiza cyane ni umucanga wa quartz kandi bisaba ubwinshi bwokuvurwa mbere yo gukama no gusuzuma kugirango ubunini bwabyo nubuziranenge byujuje ibisabwa na formula; Rimwe na rimwe isazi ivu, ifu ya slag, nibindi nabyo byongeweho nkibivanze; Imvange ikoreshwa muri rusange muke, kuva kuri 1% kugeza 3%, ariko bifite ingaruka zikomeye. Bakunze gutoranywa bakurikije ibisabwa byibicuruzwa kugirango bongere imikorere, urwego, imbaraga, kugabanuka, hamwe nubukonje bwa minisiteri.

Ni ubuhe bwoko bukunze gukoreshwa bwa poro yumye wongeyeho?

Ifu ya redxersible latex

Ifu ya redispersible latex irashobora kunoza imitungo ikurikira mumashanyarazi yumye:

Ret Kubungabunga amazi no gukora bya minisiteri ivanze vuba;

Performance Imikorere ihuza ibice bitandukanye;

Performance Guhindura no guhindura imikorere ya minisiteri;

Kunama imbaraga no guhuriza hamwe;

Kwambara birwanya;

Ili Kwihangana;

⑦ Kwiyoroshya (impermeability).

Porogaramu yagusubirwamo ifu ya latexmuburyo bworoshye bwo guhomesha minisiteri, ceramic tile binder, sisitemu yo gukingira urukuta rwo hanze, hamwe nibikoresho byo hasi byerekanaga ibisubizo byiza

Kubika amazi no kubyimba

Amazi agumana umubyimba cyane arimoselile ethersethers ya krahisi, nibindi. Ether ya selile ikoreshwa mubutaka bwumye ni methyl hydroxyethyl selulose ether (MHEC) na hydroxypropyl methyl selulose ether (HPMC).

Umukozi ugabanya amazi

Igikorwa cyibanze cyo kugabanya amazi ni ukugabanya amazi ya minisiteri, bityo bigatuma imbaraga zayo zo kwikuramo. Amazi nyamukuru agabanya amazi akoreshwa mumashanyarazi yumye arimo casein, naphthalene ishingiye kumazi agabanya amazi, kondensate ya melamine formaldehyde, na aside polyikarubike. Casein ni superplasticizer nziza cyane cyane kuri minisiteri yoroheje, ariko bitewe na kamere yayo, ubwiza bwayo nigiciro gikunze guhinduka. Naphthalene ikurikirana amazi agabanya ibintu bisanzwe bikoreshwa β- Naphthalenesulfonic acide formaldehyde kondensate.

Coagulant

Hariho ubwoko bubiri bwa coagulants: kwihuta na retarder. Ibikoresho byihuta bikoreshwa mukwihutisha igenamigambi no gukomera kwa minisiteri, na calcium ikora na lisiyumu karubone ikoreshwa cyane. Aluminate na sodium silikate irashobora kandi gukoreshwa nkibintu byihuta. Retarder ikoreshwa mugutinda gushiraho no gukomera kwa minisiteri, na aside ya tartaric, aside citric nu munyu wacyo, hamwe na gluconate yakoreshejwe neza.

Umukozi udafite amazi

Ibikoresho bitarinda amazi birimo ibice bya polymer nka chloride ya fer, ibinyabuzima bya silane organic, umunyu wa aside irike, fibre polypropilene, na reberi ya styrene butadiene. Icyuma cya chloride cyuma kitagira amazi gifite ingaruka nziza zo kwirinda amazi, ariko gikunda kwangirika kwibyuma hamwe nibice byashyizwemo ibyuma. Umunyu wa calcium udashobora gushonga uterwa nigisubizo cyumunyu wa aside irike hamwe na calcium ion mukubitsa icyiciro cya sima kurukuta rwa capillaries, bigira uruhare mukuziba imyenge no gutuma izo nkuta za capillary zihinduka hydrophobique, bityo bikagira uruhare runini rwamazi. Igiciro cyibicuruzwa biri hasi cyane, ariko bisaba igihe kirekire cyo kuvanga minisiteri hamwe namazi.

fibre

Fibre ikoreshwa mumashanyarazi yumye irimo fibre irwanya alkali, fibre polyethylene (fibre polypropilene), imbaraga nyinshi hamwe na modulus polyvinyl alcool fibre (polyvinyl alcool fibre),fibre, nibindi bikoreshwa cyane ni imbaraga-nyinshi hamwe na modulus polyvinyl inzoga nyinshi hamwe na fibre polypropilene. Imbaraga nyinshi hamwe na modulus nyinshi polyvinyl fibre alcool ifite imikorere myiza nigiciro gito ugereranije na polypropilene yatumijwe hanze. Fibre ikwirakwizwa muburyo budasanzwe kandi bumwe muri matrike ya sima, kandi igahuza cyane na sima kugirango hirindwe ishingwa niterambere rya microcrake, bigatuma matrise ya minisiteri iba mwinshi, bityo ikagira imikorere idakoresha amazi ningaruka nziza kandi ikarwanya guhangana. Uburebure ni mm 3-19.

Defoamer

Kugeza ubu, ifu ya defoamers ikoreshwa mu ifu yumye yumye ni polyoli na polysiloxane. Porogaramu ya defoamers ntishobora guhindura gusa ibintu byinshi, ariko kandi igabanya kugabanuka. Mubikorwa bifatika, kugirango tunoze imikorere yuzuye, inyongera nyinshi zigomba gukoreshwa icyarimwe. Kuri iyi ngingo, birakenewe ko twita ku ngaruka ziterwa hagati yinyongera zitandukanye. Mubyongeyeho, birakenewe kandi kwitondera umubare winyongera wongeyeho. Bake cyane kugirango bagaragaze ingaruka zinyongera; Byinshi, hashobora kubaho ingaruka mbi.
