Imikoreshereze n'imikorere ya redispersible latex ifu

Intambwe yambere mugukora ifu ya polymer isubirwamo ni ugukora polymer ikwirakwiza, izwi kandi nka emulsion cyangwa latex.Muri ubu buryo, monomers-emulisifike yamazi (ihagarikwa na emulisiferi cyangwa macromolecular irinda colloide) ikorana nababitangije kugirango batangire polymerisiyasi.Binyuze muri iyi reaction, monomers ihujwe no gukora molekile ndende (macromolecules), Byitwa polymers.Muri iki gisubizo, ibitonyanga bya monomer bihinduka polymer "ikomeye".Muri ubwo buryo bwa polymer emulisiyo, stabilisateur hejuru yibice bigomba kubuza latex muburyo ubwo aribwo bwose guhuriza hamwe bityo igahungabana.Uruvange noneho rwateguwe kugirango rwumishe spray wongeyeho inyongeramusaruro zitandukanye, kandi hiyongereyeho imiti irinda hamwe na anti-caking ituma polymer ikora ifu itemba yubusa ishobora gusubizwa mumazi nyuma yo kumisha spray.

Ifu ya redispersible latex ikwirakwizwa mumashanyarazi avanze neza.Iyo minisiteri imaze kuvangwa n'amazi, ifu ya polymer isubizwa mumashanyarazi mashya avanze hanyuma ikongera ikarekurwa;bitewe na hydrata ya sima, guhumeka hejuru hamwe na / cyangwa kwinjiza igice cyibanze, imyenge yimbere ni ubuntu Gukomeza gukoresha amazi bituma uduce duto twa latx twuma kugirango habeho firime idashobora gushonga mumazi.Iyi firime ikomeza ikorwa no guhuza ibice bimwe bitatanye muri emulsiyo mumubiri umwe.Kugirango ushoboze gusubirwamo ifu ya latx ikora firime muri minisiteri ikomye, hagomba kwemezwa ko ubushyuhe buke bwo gukora firime buri munsi yubushyuhe bwo gukiza bwa minisiteri yahinduwe.

Imiterere yibice byifu ya polymer isubirwamo nuburyo bukora firime nyuma yogusubiramo bituma bishoboka kugira ingaruka zikurikira kumikorere ya minisiteri muburyo bushya kandi bukomeye:

1. Imikorere muri minisiteri nshya

Effect "Ingaruka yo gusiga" ibice bituma imvange ya minisiteri igira amazi meza, kugirango ibone imikorere myiza yubwubatsi.

Effect Ingaruka yinjira mu kirere ituma minisiteri igabanuka, bigatuma kugenda byoroshye.

Ongeraho ubwoko butandukanye bwifu ya redxersible ya poro irashobora kubona minisiteri yahinduwe hamwe na plastike nziza cyangwa nziza cyane.

2. Imikorere muri minisiteri ikomeye

Filime ya latex irashobora gukuraho ibice byo kugabanuka kuri base-mortar kandi igakiza ibice byo kugabanuka.

Kunoza uburyo bwa minisiteri.

Gutezimbere imbaraga zifatika za minisiteri: kuba hari uturere tworoshye cyane kandi tworoshye cyane twa polymer bitezimbere ubworoherane nubworoherane bwa minisiteri,

Itanga imyitwarire ifatika kandi ifite imbaraga kuri skelet ikomeye.Iyo imbaraga zashyizwe mubikorwa, bitewe nuburyo bworoshye bwo guhinduka no guhindagurika

Microcrack ziratinda kugeza impagarara nyinshi zigeze.

Polymer Imiyoboro ya polymer ihuriweho nayo ibuza guhuriza hamwe microcrack mu gucengera.Kubwibyo, isupu ya polymer isubirwamo itera kunanirwa kunanirwa no kunanirwa kwibikoresho.

Birakenewe kongeramo ifu ya redxersible latex kumashanyarazi ya sima yumye, kuko ifu ya redxersible latex ifitemo inyungu esheshatu zikurikira, kandi ibikurikira ni intangiriro kuri wewe.

1. Kunoza imbaraga zo guhuza hamwe

Ifu ya redispersible latex igira uruhare runini mugutezimbere imbaraga zo guhuza hamwe no guhuza ibikoresho.Bitewe no kwinjirira mubice bya polymer mumyenge na capillaries ya materique ya sima, ubumwe bwiza bubaho nyuma yo kuvangwa na sima.Polymer resin ubwayo ifite ibintu byiza cyane.Ifite akamaro kanini mugutezimbere ibicuruzwa bya sima ya sima kubutaka, cyane cyane gufatana nabi kwingingo zidasanzwe nka sima kubutaka kama nkibiti, fibre, PVC, na EPS.

2. Kunoza ubukonje-gukonjesha no gukumira neza ibikoresho

Ifu ya redispersible latex, plastike yububiko bwayo bwa termoplastique irashobora gutsinda ibyangiritse byatewe no kwaguka kwinshi no kugabanuka kwibikoresho bya sima biterwa no gutandukanya ubushyuhe.Kunesha ibiranga kugabanuka kwumye no gutobora byoroshye bya sima ya sima, birashobora gutuma ibintu bihinduka, bityo bikazamura igihe kirekire cyibintu.

3. Kunoza kunama no guhangana

Muri skeleton ikaze yakozwe nyuma ya sima ya sima ihumeka, polymer membrane iroroshye kandi irakomeye, kandi ikora nkigice cyimuka hagati ya sima ya sima, ishobora kwihanganira imitwaro myinshi kandi igabanya imihangayiko.Kwiyongera kurakara no kunama.

4. Kunoza kurwanya ingaruka

Redispersible latex ifu ni resmoplastique.Filime yoroshye yubatswe hejuru yubutaka bwa minisiteri irashobora gukuramo ingaruka zimbaraga zo hanze kandi ikaruhuka itavunitse, bityo bikazamura ingaruka ziterwa na minisiteri.

5. Kunoza hydrophobicity no kugabanya kwinjiza amazi

Ongeramo cakao redispersible polymer ifu irashobora kunoza microstructure ya sima ya sima.Polimeri yacyo ikora umuyoboro udasubirwaho mugihe cya hydrata ya sima, igafunga capillary muri gel ya sima, ikabuza kwinjira mumazi, kandi ikanoza ubudahangarwa.

6. Kunoza imyambarire no kwihangana

Ongeramo ifu ya redxersible latex irashobora kongera ubwuzuzanye hagati ya sima ya minisiteri na firime ya polymer.Kwiyongera kwingufu zifatanije nabyo byongera ubushobozi bwa minisiteri yo guhangana nihungabana ryogosha, kugabanya igipimo cyimyambarire, kunoza imyambarire, no kongera ubuzima bwa minisiteri.
