CTPB cas 586976-24-1 Carboxyl-Terminated Polybutadiene CTPB
Ka kiia ko te rapa polybutadiene wai kua mutu te Carboxyl he CTPB mo te poto. He carboxyl kei nga pito e rua o te ngota ngota polymeric, ka mau tenei polymer i te hanganga ki te taha o te roopu carboxyl, he pai te tohatoha o te whatunga me te kore he tauranga kore utu. no reira he pai te mahi miihini.
Ka taea e nga roopu mutunga o te carboxyl te tauhohe me te kapia epoxy, he pai te whakakaha ki te kapia epoxy. Ka whakatauritea ki te CTBN, he iti ake te kirikiri o te CTPB, he pai ake te mahi o te pāmahana iti me te ngawari.
Ko te hua ka taea te whakamahi i roto i te toka toka toka toka, engari ka taea hoki te whakamahi i roto i nga elastomers, adhesives, hiri rawa, epoxy resin whakarerekētanga me te hiko hiko.
Kikī i roto i te 50kg/drum, 180kg/drum, Ko te wa rokiroki he 1 tau.
Nga tohutohu haumaru:
Ko te rokiroki me noho ki te hauhautanga, maroke me te hau. Ko te ahua pai kei waenga i te -20 ~ 38 ℃. 12 marama te roa o te oranga, mena ka pau, ka whakamahia tonu mena ka eke ki te paerewa ma te whakamatautau ano. I te wa e tika ana te kawe i te ua, te ra. Kaua e uru ki te oxidizer kaha.
