Codsiga

Xabagta laba qaybood ka kooban waa in la isticmaalaa gudaha muddada lagu dabaqi karo ka dib marka la geliyo RE.Dhererka muddada lagu dabaqi karo ma aha oo kaliya la xidhiidha maadada polymer ee koollada, laakiin sidoo kale qaybaha kale ee khuseeya (sida resin, antioxygen, plasticizer, dareeraha, iwm.
Marka ay ku dhowdahay xilliga lagu dabaqi karo, badiyaa dhowr saacadood ama hal maalin oo shaqo ah, koollada ayaa aad u adkaan doonta in la shaqeeyo, iyo viscosity-ku dhaqso ayuu u kacaa.Ugu dambeyntii, Waxay noqotaa jelly aan la beddeli karin.100 xabag tayo leh, Hydroxyl polyurethane (Polyurethane xisaabteeda qiyaastii 20%), qiyaasta RE 4-7.Chloroprene caag ah (koobka caagga ah qiyaastii 20%), RICHEST RE wuxuu sameeyaa 4-7.
