Gukoresha ifu ya polymer itatanye mumurima wubwubatsi

Ifu ya polymer isubirwamoni inyongera nyamukuru yifu yumye yiteguye kuvangwa na minisiteri nka sima cyangwa gypsumu.

Ifu ya redispersible latex ni polymer emulioni yumuti wumye kandi igateranyirizwa hamwe kuva 2um yambere kugirango ibe uduce duto twa 80 ~ 120um. Kuberako ubuso bwibice bisizwe hamwe nifu ya organic, ikomeye-idashobora kwihanganira ifu, tubona ifu ya polymer yumye. Basukwa byoroshye cyangwa bagapakira kubikwa mububiko. Iyo ifu ivanze n'amazi, sima cyangwa gypsumu ishingiye kuri gypsumu, irashobora gusubirwamo, kandi ibice by'ibanze (2um) muri byo bizongera gukora kuri leta ihwanye na latx y'umwimerere, bityo ikaba yitwa redispersible latex powder.

Ifite isubiranamo ryiza, irongera ikwirakwira muri emulsiyo ihuye namazi, kandi ifite imiti imwe nki ya emulsiyo yambere. Mugushyiramo ifu ya polymer isubirwamo kuri sima cyangwa gypsumu ishingiye kumafu yumye yiteguye kuvangwa na minisiteri, ibintu bitandukanye bya minisiteri birashobora kunozwa,

Umwanya wo kubaka

1 Sisitemu yo Kurinda Urukuta

Irashobora kwemeza neza guhuza ikibaho cya minisiteri na polystirene nizindi substrate, kandi ntabwo byoroshye guhita no kugwa. Gutezimbere guhinduka, kurwanya ingaruka no kunoza imbaraga.

Amatafari 2

Itanga imbaraga-ndende cyane kuri minisiteri, itanga minisiteri ihindagurika kugirango ihindure coefficient zitandukanye zo kwagura ubushyuhe bwa substrate na tile.

Inkono 3

Ifu ya polymer isubirwamo ituma minisiteri itinjira kandi ikabuza kwinjira mumazi. Mugihe kimwe, ifite gufatana neza hamwe nuruhande rwa tile, kugabanuka guke no guhinduka.

Imigaragarire 4

Irashobora kuziba icyuho cya substrate, kugabanya kwinjiza amazi kurukuta, kunoza imbaraga zubuso bwa substrate, no kwemeza gufatana na minisiteri.

5 Kwiyoroshya hasi

Kunoza uburyo bwo guhangana no kwikuramo, kongerera imbaraga guhuza hamwe nu gice cyo hasi, kunoza ubumwe, guhangana no gukomera no kugonda imbaraga za minisiteri.

Amabuye 6 adafite amazi

Ifu ya redispersible latex irashobora kunoza imikorere; wongeyeho kongera amazi; kunoza amazi ya sima; gabanya modulus ya elastike ya minisiteri kandi wongere ubwuzuzanye hamwe na base base. Kunoza ubucucike bwa minisiteri, kongera ubworoherane, kurwanya guhangana cyangwa kugira ubushobozi bwo ikiraro.

7 gusana

Wemeze gufatisha minisiteri no kongera uburebure bwubuso bwasanwe. Kugabanya modulus ya elastike ituma irwanya cyane imbaraga.

8 putty

Mugabanye modulike ya elastike ya minisiteri, yongere ubwuzuzanye hamwe nigitereko fatizo, yongere ubworoherane, irwanya gucika, kunoza uburyo bwo kurwanya ifu igwa, kugirango putty igire imbaraga zimwe na zimwe zidashobora kwangirika nubushuhe, bishobora gukuraho ibyangijwe nubushyuhe bwubushyuhe .
