Cov khoom no yog cov nplaum dej-soluble, uas yog cov nplaum thermoplastic npaj los ntawm polymerization ntawm vinyl acetate monomer nyob rau hauv qhov kev txiav txim ntawm tus neeg pib.Nws feem ntau hu ua dawb latex lossis PVAC emulsion luv luv.Nws lub npe tshuaj yog polyvinyl acetate nplaum.Nws yog tsim los ntawm acetic acid thiab ethylene los ua ke vinyl acetate nrog titanium dioxide ntxiv (qib qis ntxiv nrog lub teeb calcium, talc, thiab lwm yam hmoov).Tom qab ntawd lawv yog polymerized los ntawm emulsion.Raws li ib tug milky dawb tuab kua.
Kev ziab sai, zoo pib tack, ua haujlwm zoo;muaj zog adhesion, siab compressive zog;muaj zog kub tsis kam.
kev ua tau zoo
(1) Cov latex dawb muaj cov txiaj ntsig zoo xws li kev kho qhov kub thiab txias, kho sai dua, muaj zog sib txuas dua, thiab cov txheej txheem sib txuas tau zoo dua toughness thiab durability thiab tsis yooj yim rau hnub nyoog.Nws tuaj yeem siv dav rau kev sib txuas cov khoom lag luam (wallpaper), thiab tuaj yeem siv los ua cov nplaum rau cov dej tsis zoo thiab cov ntoo.
(2) Nws siv dej ua cov khoom tawg, muaj kev nyab xeeb rau kev siv, tsis muaj tshuaj lom, tsis muaj hluav taws xob, yooj yim los ntxuav, solidifies ntawm chav tsev kub, muaj adhesion zoo rau ntoo, ntawv thiab ntaub, muaj zog sib txuas, thiab kho Adhesive txheej yog xim tsis muaj pob tshab, zoo toughness, tsis ua phem rau cov khoom sib txuas.
(3) Nws kuj tuaj yeem siv los ua kev hloov kho ntawm phenolic resin, urea-formaldehyde resin thiab lwm yam nplaum, thiab siv los ua polyvinyl acetate latex xim.
(4) Lub emulsion muaj kev ruaj ntseg zoo, thiab lub sijhawm cia tuaj yeem ncav cuag ntau tshaj li ib nrab xyoo.Yog li ntawd, nws tuaj yeem siv dav hauv kev luam ntawv thiab kev khi, rooj tog tsim, thiab kev sib txuas ntawm cov ntawv, ntoo, ntaub, tawv, ceramics, thiab lwm yam.
Nta
1. Nws muaj zog adhesion rau cov ntaub ntawv ntxeem tau xws li ntoo, ntawv, paj rwb, tawv, ceramics, thiab lwm yam., thiab thawj viscosity kuj siab.
2. Nws tuaj yeem kho tau ntawm chav tsev kub, thiab kev kho kom ceev ceev.
3. Cov yeeb yaj kiab yog pob tshab, tsis muaj kuab paug rau adherend, thiab yooj yim rau kev ua.
4. Siv dej los ua qhov nruab nrab dispersion, nws tsis kub hnyiab, tsis muaj cov pa phem, tsis ua phem rau ib puag ncig, thiab muaj kev nyab xeeb thiab tsis muaj kuab lom.
5. Nws yog ib qho ua kua dej khov, uas yooj yim dua rau kev siv.
6. Cov yeeb yaj kiab kho tau muaj qee qhov kev nyuaj siab, tsis kam rau dilute alkali, dilute acid, thiab roj kuj.
Nws yog tsuas yog siv rau hauv kev ua ntoo, rooj tog sib dhos, luam yeeb nozzles, kev tsim kho kom zoo nkauj, cov ntaub ntawv sib txuas, cov khoom lag luam, luam ntawv thiab khi, kev tsim khoom siv tes ua, tawv ua, daim ntawv lo kho, pobzeb nplaum, thiab lwm yam.
zog
Ib puag ncig tus phooj ywg dawb latex yuav tsum ua ntej kom muaj kev sib raug zoo txaus, thiaj li ua kom ntseeg tau tias cov khoom zoo ntawm cov ntawv yuav tsis cuam tshuam tom qab kev sib txuas.
Txhawm rau txiav txim siab seb lub zog sib txuas ntawm ib puag ncig tus phooj ywg dawb latex puas tsim nyog, ob daim ntawm cov khoom sib txuas tuaj yeem raug torn sib nrug ntawm kev sib txuas lus.Yog tias cov ntaub ntawv sib txuas tau pom tias puas tom qab tawg, lub zog sib txuas yog txaus;Yog tias tsuas yog qhov sib txuas sib txuas sib cais, Nws qhia tau tias lub zog ntawm ib puag ncig tus phooj ywg dawb latex tsis txaus.Qee lub sij hawm cov latex dawb dawb uas tsis zoo ib puag ncig nrog kev ua haujlwm tsis zoo yuav degummed thiab cov yeeb yaj kiab yuav dhau los ua nkig tom qab khaws cia rau lub sijhawm ntawm qhov kub thiab txias ib puag ncig.Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua qhov kub thiab txias thermal hloov thiab tsis tshua muaj kub embrittlement thwmsim los txiav txim seb nws qhov zoo yog txhim khu kev qha.
