Polyvinyl cawv (PVA) hmoovyog dej-soluble hluavtaws polymer muab tau los ntawm polyvinyl acetate los ntawm hydrolysis. Nws zoo nkaus li zoo, dawb rau tawm - cov hmoov dawb uas yaj yooj yim hauv dej txias. Qhov tseeb, PVA tuaj nyob rau hauv peb daim ntawv, flake, granular, hmoov. Tom qab ntawd cov hmoov PVA muaj 80 mesh, 120 mesh. Peb muajBP05S (0588 120 mesh), BP17S (1788 120 mesh), BP24S (2488 120 mesh). Tsis muaj teeb meem loj, lossis qhov me me, ob qho tib si siv tau.
Txawm li cas los xij, koj yuav zoo dua xyuas seb hom viscosity PVA hmoov zoo li cas? Tsawg viscosity, meduim viscosity lossis siab viscosity? Peb muaj nyob rau hauv Tshuag.
