Ubwoko bwa powder ya polymer ikunze gukoreshwa muri sisitemu yo kubaka

Amashanyarazi avanze yumye nuruvange rwibikoresho bya sima (sima, isazi yisazi, ifu ya slag, nibindi), igiteranyo cyiza cyo mu cyiciro cyiza (umucanga wa quartz, corundum, nibindi, kandi rimwe na rimwe bisaba Granules yoroheje, yagutse perlite, yaguye vermiculite, nibindi. ) hamwe nibindi bivangwa bivangwa kimwe mubice runaka, hanyuma bigapakirwa mumifuka, ingunguru cyangwa bigatangwa kubwinshi muri poro yumye nkibikoresho byubaka.

Hariho ubwoko bwinshi bwa minisiteri yubucuruzi, harimo ifu yumye yumukono wububiko, ifu yumye yumye yo guhomesha, ifu yumye yumutaka kubutaka, ifu yumye yumye idasanzwe yo kwirinda amazi, kubika ubushyuhe nibindi bikorwa. Mu ncamake, minisiteri ivanze yumye irashobora kugabanywamo minisiteri isanzwe ivanze (masonry, plaster hamwe nubutaka bwumye buvanze) na minisiteri idasanzwe ivanze. Ikimasa kidasanzwe kivanze kirimo: kwipima hasi hasi, ibikoresho birwanya kwambara, ibikoresho bidafite ingufu za kawking, minisiteri itagira amazi, minisiteri yangiza amazi, ibikoresho byo gukingira hejuru ya beto, minisiteri yamabara, nibindi.

Byinshi rero byumye-bivanze na minisiteri bisaba kuvanga ubwoko butandukanye hamwe nuburyo butandukanye bwibikorwa bigomba gukorwa hakoreshejwe umubare munini wibizamini. Ugereranije n’ibisanzwe bivangwa na beto, ibivanze byumye bivanze birashobora gukoreshwa gusa muburyo bwifu, naho icya kabiri, bigashonga mumazi akonje, cyangwa bigashonga buhoro buhoro bitewe nigikorwa cya alkaline kugirango bigire ingaruka zikwiye.

Ifu ya Redispersible latex mubusanzwe ni ifu yera ifite amazi yumye, hamwe nivu ireshya na 12%, kandi ivu rituruka kumukozi urekura. Ingano isanzwe yubunini bwa polymer ni 0.08mm. Birumvikana, ubu nubunini bwa emulsion agace kegeranye. Nyuma yo gusubira mumazi, ubunini busanzwe bwa emulsion ni 1 ~ 5um. Ingano isanzwe yubunini bwa emulsion ikoreshwa muburyo bwa emulsiyo muri rusange ni 0.2um, bityo ingano yingingo ya emulsiyo yakozwe nifu ya polymer nini cyane. Igikorwa nyamukuru nukwongera imbaraga zihuza za minisiteri, kunoza ubukana bwayo, guhindagurika, kurwanya imivurungano no kudahinduka, no kunoza uburyo bwo gufata amazi no gutuza kwa minisiteri.

Ifu ya polymer isubirwamo ifu ya polymer ikoreshwa muri poro yumye ahanini irimo ubwoko bukurikira:

(1) styrene-butadiene copolymer;
(2) Stolyne-acrylic acide copolymer;
(3) vinyl acetate homopolymer;
(4) polyacrylate homopolymer;
(5) Styrene acetate copolymer;
