Koj Xov Tawj Yias?

Kev lees paub txog kev tiv thaiv dej

Thaum xaiv hom zoo thiab kev pab tshuaj lwm, pej xeem tuaj kom zoo dua rau kev tiv thaiv dej thiab kev nyuaj siab rau kev siv ntau yam tshwj xeeb los ntawm PVA thiab VAE systems.

Tshuaj ntxuav nrog qhov meej meej

Pej xeem muab cov ntaub ntawv tshuaj ntxuav nrog meej meej xws li kev ua siab thiab kev ua kom dej sov, pab cov neeg siv khoom txuag kev tshawb nrhiav thiab kev xaiv khoom zoo dua.

Tus cwj pwm tseem ceeb rau kev sib thaj yees ntev

Pej xeem xav tias yuav tswj xyuas kev sib thaj yees ntev los ntawm kev muab khoom tsim nyog, kev pab tswj xyuas zoo ib yam, thiab kev pab tshuaj lwm tseem ceeb uas pib ntxig nrog kev lag luam ntawm pej xeem.

Cov khoom sib xws

Polyvinyl alcohol (PVA) yog polymers uas tseem ceeb rau ntau qhov chaw tsim khoom, xws li daim ntawv, phau, thiab kev tsim kho. PVA tau siv los ua thawj rau daim ntawv thiab kev them, muab kev nyiaj sib ntxiv thiab kev ua haujlwm zoo. Nws kuj yog ib qhov tseem ceeb rau phau, uas siv los ua thawj rau kev nres tsev thiab kev tso tshuaj rau kev tshuab. Nyob hauv kev tsim kho, PVA pab txhim kho kev ua haujlwm ntawm cov khoom uas muaj cement, pab txhim kho kev ua haujlwm thiab kom tsis txhob muaj kev tshuaj ntxhiab hauv cov khoom siv ntau.

Cov Lus Nug Nrov

Yuav ua li cas cov duab ntawm duab ntawm polymer uas tuaj yeem rov qab siv tau yooj yim dua li cov emulsion hlwb?

Cov duab ntawm duab ntawm polymer uas tuaj yeem rov qab siv tau muab kev yooj yim dua rau kev sau, kev nres, thiab kev nres tshaj tawv dua li cov emulsion hlwb. Thaum muab ntxiv nrog dej, nws rov qab siv los ua emulsion, rov qab muab kev sib sau thiab kev yooj yim rau hauv cov khoom siv hluv lossis cov khoom siv gypsum.
Lub adhesive tshuab PVA yog zoo tshaj rau daim ntawv, txiv kab, kab ntsa, thiab lwm yam khoom tshuab cellulose. Lub adhesive tshuab no yog siv dej ntau, tsis muaj tshuab solvent, zoo rau dej thiab ntuj, thiab tso caij ntau rau kev sib txuas nrog kev siv meej thiab kev ua tau zoo tib yam.
APS ua li thiab los pab sim kho nyob rau hauv qhov chaw sib ntxig. Nws feem ntau siv rau hauv kev tsim kho acrylic, vinyl, thiab kho tshwj xeeb uas xav tau kev sib cuag zoo thiab muaj ceev tshwj xeeb.
Potassium persulfate siv los yog thawj kis tes polymerization thiab thawj kis oxidizing nyob rau hauv kev tsim kho synthetic resin thiab polymer. Nws pab tso caij kho tseg zoo thiab kev txawj mob tshwm sim nyob rau hauv kev tsim kho uas raug sau npe.
