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 ib qhov polymer siv tau ntau hauv cheeb tsheb uas tuaj yeem siv hauv kev lag luam ntau yam. Qhov tswj hwm los tsim cov roj yaig meej tshaj no tso nws nyob rau hauv kev siv rau roj yaig tiv thaiv, kev ntxig, thiab tshuaj xaum. Hauv kev lag luam kis tes, PVA raug sau rau hauv cov dej thiab mortar kom txhim khu kev nyuaj siab thiab kev nyob ntev ntawm cov khoom siv rau kis tes. Tom qab ntawd, qhov tshwm sim ntawm PVA uas tuaj yeem raug tua los yog raug huv los yog raug suab nrog tej menyuam yog ib qhov kev xaiv yooj yim rau kev siv rau packaging thiab film.

Cov Lus Nug Nrov

Redispersible polymer powder siv rau dab tsi hauv kev tshen?

Cov duab ntawm polymer pheej xwm tau zoo dua, zoo li muaj kev txuas ntxiv siab, kev ua haujlwm zoo dua, thiab kev tso siab rau dej hauv cov khoom siv tsim kho. Cov khoom no feem ntau siv rau kev ntxig kab, siv rau kab ntxig dej, siv rau kab ntxig hauv tsev, thiab rau kev ruaj khov hauv tsev kom zoo dua.
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.
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.
Ammonium persulfate raug siv ntau los pab qhia kev tsim polymer emulsion thiab solution rau acrylic polymers thiab latexes. Nws muaj qhov tseem ceeb hauv kev siv hauv dej, kev tseem ceeb, thiab kev lag lag nyob hauv kev lag lag tshuaj lom neeg.
