Dej-dispersion xim: lub hom thiab cov khoom

Dej-dispersion xim tsev pom tau hais tias ib tug ntawm cov yooj yim tshaj plaws thiab nqi-zoo lub tsev ntaub ntawv. Vim lub fact tias lawv tsis muaj organic solvents, lawv muaj yuav luag tsis muaj ntxhiab tsw. Dej-dispersion xim tsev yog kev ruaj ntseg kiag los ntawm ib tug tej taw tes ntawm view. Lawv muaj zoo adhesion mus rau ib tug ntau ntawm cov sib txawv ntawm cov chaw. Lawv yuav tsum muaj ntaub ntawv los ntawm cov tshuaj tsuag, cov menyuam los yog xim txhuam. Lawv muaj zoo heev zoo. Tsaug rau cov khoom, cov xim muaj hlau dispersion occupies ib tug uas txoj hauj lwm ntawm cov ntaub ntawv siv rau txheej rau ntawm qhov chaw.

Phau ntawv hais ntawm no cov ntaub ntawv uas yog dispersed thoob plaws nws volume, tom qab evaporation ntawm noo lawv sib. Lawv lo rau txhua lub lwm yam raws li qhov kev sib cuag, txoj kev ua ib zaj duab xis. Dej-dispersion xim tsev feem ntau tsim dawb. Yuav kom tau txais cov xim uas koj xav tau, los yog cia li hais txog tej ntxoov ntxoo ntawm Kohler thov toning dyes. Tinting yuav ua tau ob qho tib si manually thiab nrog rau cov kev pab los ntawm tshwj xeeb cov cav tov. Lub ntsiab disadvantage ntawm cov thawj yog cov muaj teeb meem nyob rau hauv kev ua raws cai nrog tib yam proportions kom tau tib yam xim nyob rau hauv cov nram no nws. Uas yog vim li cas tag nrho cov manufacturers siv tinting machines thiab daim card (ntxoov ntxoo tooj, faib ua feem).

Dej-dispersion xim raug muab faib ua ob peb hom nyob rau hauv lub phau ntawv. Cov uas pheej yig tshaj thiab txwv tsis pub thov - cov ntaub ntawv raws li nyob rau hauv PVA (polyvinyl acetate). Lawv mas siv rau dyeing cov phab ntsa thiab ceilings nyob rau hauv thaj chaw uas muaj tsawg humidity. Nyob rau hauv cov ntaub ntawv ntawm kev ntxiv rau acrylic polymers yuav ua tau kom puas kuj thiab dej kuj ntawm lub txheej yav tom ntej. Styrene-butadiene phau ntawv ntaub ntawv muaj zoo kuj mus ya raws, tab sis tsis tau tso raug rau ultraviolet tawg thiab daj nyob rau hauv lub hnub. Vim li no, lawv yog siv nyob rau hauv vaj tse nyob rau hauv cov chav nrog dag teeb pom kev zoo.

Dej-dispersive xim Acrylic (nyob qhov twg li losis tswvyim dabtsi - tsuas yog cov polymer) yog lub feem ntau ntau yam. Feem ntau ntawm cov ntaub ntawv ua niaj hnub no, lub caij nplooj zeeg mus rau hauv pawg no, lawv yog feem ntau siv rau painting tej hauj lwm.

Xim nyob rau hauv no vim tintable zoo. Txawm li cas los, lawv cov kev siv yog tsim nyog nyob rau hauv cov kev xaiv ntawm cov xim coj cov khoom los ntawm tib lub chaw tsim tshuaj paus, raws li nws tej zaum yuav tsis phim vim sib txawv nyob rau hauv tinting systems. Xim raws li acrylic dries sai sai. Lawv zoo taus raug tshav ntuj. Tej ntaub ntawv tso cai rau kom tau ib elastic cover, ze zoo tej kab nrib pleb, zoo taus thiab ntxuav yog ntev txaus. Muaj cov variations, qhia tshwj xeeb uas siv tau rau painting "nyob" ntoo. Tej xim tsev nce yooj thiab zoo dej vapor permeability ua ke nrog cov dej-repellent zog.

Tsis hais txog ntawm lub hom phau ntawv cov ntaub ntawv uas nyob rau hauv xws li xim tsev muaj ib tug muaj zog chaw: lawv ua puas nyob rau hauv cov kev tshwm sim ntawm khov, li ntawd los ntawm khaws cia ib tug zoo kub yuav tsum tau tiav.
