Daim ntawv thov

Ob daim nplaum nplaum yuav tsum tau siv nyob rau hauv lub sijhawm siv tau tom qab muab tso rau hauv RE.Lub sijhawm siv sijhawm ntev tsis yog tsuas yog cuam tshuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj lwm yam cuam tshuam (xws li resin, antioxygen, plasticizer, hnyav, thiab lwm yam.
Thaum nyob ze rau lub sijhawm siv, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum ua haujlwm nyuaj dua, thiab viscosity nce sai sai.Thaum kawg, Nws dhau los ua jelly irreversible.100 zoo nplaum, Hydroxyl polyurethane (Polyurethane account rau ib ncig ntawm 20%), RE koob 4-7.chloroprene roj hmab (Rubber account rau ib ncig ntawm 20%), RICHEST RE ua 4-7.
