Wanwei PVA 23-99(H) & PVA 100-50(H)
Piav qhia
Saib xyuas
PVA qhov zoo nkauj yog dawb flake, granular lossis powdery solid (low-alkali alcoholysis txheej) lossis dawb flocculent solid (high-alkali alcoholysis txheej). Nws yog ib hom polymer soluble hauv dej nrog kev siv dav, thiab nws cov haujlwm yog nyob nruab nrab ntawm yas thiab rubber. Nws muaj qhov tshwj xeeb muaj zog adhesion, film flexibility, roj tiv thaiv, surface activity, gas barrier, wear resistance thiab lwm yam.

Kev tsim tsev hluav
Polyvinyl alcohol tau los thaum lub ntsiab lus rau kev txhim kho qib ntawm kev tsim tsev hluav los ntawm peb qhov kev ua haujlwm: hydrogen bonding, rheology regulation thiab water retention thiab film formation. Nws yog thawj li ntawm kev lag luam zoo dua, kev rheology zoo dua, kev kho kom huv siab zoo dua thiab kev zoo dua rau qhov chav haujlwm.
Kev ntim cov neeg ua siab
Nyob rau hauv nws peb yam ntsiab lus zoo heev ntawm strong film-forming, precise adhesion, thiab environmentally friendly desizing, polyvinyl alcohol tau los thaum "daim ntawv hlau" rau cov neeg ua siab nyob rau hauv cheeb tsam no, muaj cov lus nug xws li dynamic protection, technological innovation, thiab sustainability.
Colloid Protective Agent
Nrog rau nws lub sijhawm molecular amphiphilic thiab cov lej ntau yooj (alcoholysis degree, polymerization degree), polyvinyl alcohol tau txais kev nyob qab hauv colloidal protective agents los ntawm lwm hom mechanism "adsorption-film formation-space barrier". Nws tus khaub ncaws ua haujlwm hauv cov chaw xws li paper coatings, emulsion polymerization, building material slurry, thiab lwm yam, tsis only ua rau zoo dua li cov khoom lag luam (xws li kev nyob hauv kho thiab kev ua haujlwm zoo), tab sis kuj pab rau kev pab cuam tshuav (non-formaldehyde, degradable).
Kev nyob qab peev
Qhov tseeb loj ntawm polyvinyl alcohol hauv cov stabilizers yog nws lub sijhawm nyob qab ntau: los ntawm kev saib xyuas interface, kev saib xyuas kev ua haujlwm thiab kev ua siab, nws paub txog emulsions thiab suspensions zoo ib zaug.

Khaws
Thov zam kev tsim lossis khaws cov av. Ua kom muaj kev ceev faj tiv thaiv cov hluav taws xob, nplai/kev nplai txhua lub cuab yeej. Thov zam kev tiv tauj nrog cov khoom kub lossis molten. Tsis txhob hnoos av, fumes lossis vapors los ntawm cov khoom kub. Siv cov huab cua tawm hauv cheeb tsam txheej. Ua kom muaj kev ceev faj tiv thaiv hnub ci ncaj thiab nag txhuam thaum thauj. Khaws cov tsheb thauj khoom kom huv. Thov zam kev puas tsuaj ntawm cov pob thiab khaws deb ntawm cov impurities.
