Daim ntawv thov

Raws li re-wetting nplaum

PVA BP04 yog siv los ua ib qho re-wetting adhesive, leveraging nws tus yam ntxwv ntawm activating raws li kev sib cuag nrog dej thiab kev sib raug zoo tom qab ziab. Yog li nws yog siv rau hauv cov ntawv xa nyiaj, hnab ntawv, cov ntawv lo. PVA BP04 yog coated rau ntawm daim ntawv thaub qab. Nws ua tsis yog -tacky thaum qhuav thiab tsuas yog nce adhesiveness thaum moistened nrog dej.

Suspending agent

PVA BP04 yog siv los tiv thaiv colloid rau polymerization ntawm PVAC. Tiv thaiv cov khoom polymer los ntawm coalescing (ua ke ua ke) thaum lub sij hawm polymerization. Thiab siv nyob rau hauv ncua kev kawm ntawv polymerization (xws li, rau PVC) disperse monomer droplets nyob rau hauv dej.
