Pu Mold Resin
Pu Mold Resin
LAXANKA
Waxay ka kooban tahay qaybta A&B, A waa polyol, iyo B waa polyurethane prepolymer Iso-joojiyay.
Tilmaamaha
Waxay leedahay sifooyin processing aad u fiican, waqti gel gaaban, adag in heerkulka caadiga ah.Alaabta la dhammeeyey waxay leedahay sifooyin wanaagsan oo caabbinta nabarka, anti-hydrolyzing, daahfurnaanta, adkeysi wanaagsan iyo cabbir deggan.
CODSIGA
Loo isticmaalo samaynta kabaha iyo noocyada kala duwan ee caaryada PU.Beddelka caagga Silicon si uu u sameeyo qaabka dhagaxa dhaqameed.
KAYDINTA
Ku kaydi meel qabow oo qallalan.Haddii aadan hal mar isticmaali karin, fadlan buuxi gaaska Nitrogen oo si fiican u xir durbaanka.Nolosha shelf ee xirmada asalka ah waa 6 bilood.
