Product Description
PVA / Polyvinyl cawv, organic compound, dawb flake, flocculent los yog hmoov khoom, odorless.Dissolved nyob rau hauv dej. Me ntsis soluble hauv dimethyl sulfoxide. Polyvinyl cawv yog ib qho tseem ceeb tshuaj raw khoom siv los ua polyvinyl polymer, roj av- cov kav dej thiab cov hluavtaws hluavtaws, cov ntaub ntawv kho mob, emulsifiers, ntawv txheej, nplaum, nplaum, thiab lwm yam.
Polyvinyl cawv PVA
Nws yog dej-soluble polymer tau los ntawm hydrolysis ntawm polyvinyl acetate (PVA).Nws yog xim dawb los yog daj me ntsis hmoov / granular khoom uas tsis yog- tshuaj lom, ntxhiab tsw, thiab muaj cov yeeb yaj kiab zoo- sib sau, sib txuas, thiab tshuaj lom neeg ruaj khov.
1. Zaj duab xis tsim cov cuab yeej
Nws tsim cov pob tshab, tawv zaj duab xis nrog zoo txhua yam muaj zog thiab airtightness.
2.Adhesion
Nws muaj adhesion zoo rau cov cement thiab lwm cov ntaub ntawv gelling.
3. Chemical Stability
Nws muaj cov roj zoo thiab hnyav tsis kam thiab biodegradability zoo heev.
4. Solubility
Nws tuaj yeem yaj hauv dej txias lossis dej kub (nyob ntawm qib ntawm hydrolysis) los tsim cov kua nplaum pob tshab.
5.Emulsifying Thickening Properties
Nws tuaj yeem siv los ua emulsion stabilizer thiab rheology hloov kho.
6. Muaj peev xwm tuav tau siab
Lub peev xwm khaws cia siab yog hais txog lub peev xwm ntawm cov pob zeb kom tswj tau nws qhov kev ua haujlwm thawj zaug (flowability, cohesiveness, thiab dej tuav) rau ib lub sij hawm txuas ntxiv thaum sib xyaw, kev thauj mus los, siv, thiab nchuav, tsis tas yuav los ntshav, sib cais, lossis ziab hnyav. Kev ruaj khov siab muaj peev xwm ua tiav los ntawm kev siv siab -polycarboxylate ether superplasticizers zoo, muab kev tuav zoo rau ntev txog 4 teev, ua kom muaj kev tsim kho du.
