EHTPB epoxidation-HTPB Polybutadien-ka la joojiyay Epoxidized hydroxyl (epoxy-HTPB)
EHTPB waaHTPB silsilad molecular ah oo soo bandhigta kooxaha epoxy, kuwaas oo leh faa'iidooyin sida iska caabbinta saliidda, iska caabbinta gabowga, hufnaan wanaagsan, iyo waxqabad heerkul hooseeya oo wanaagsan. Kooxaha hydroxyl ee dhammaadka silsiladda molecular iyo kooxaha hydroxyl ee silsiladda molecular
Kooxda epoxy waa koox falcelis ah oo lagu daaweyn karo isocyanates kala duwan iyo wakiillo daaweyn epoxy ah.
Polymer-ka la daaweeyay wuxuu leeyahay sifooyin jireed iyo kiimiko oo wanaagsan, xoog dhejis ah oo aad u fiican oo loogu talagalay agabyo kala duwan oo aan bir ahayn sida biraha iyo galaaska, sifooyin dielectric oo wanaagsan, heer hoos u dhac yar, iyo adkaansho
Heer sare, oo deggan ilaa alkali iyo inta badan mugga, ayaa si weyn u hagaajin kara sifooyinka farsamada, xoogga dhejiska, iyo iska caabbinta kulaylka ee walxaha polyurethane
EHTPB waxaa loo isticmaali karaa dhejisyada, shaabadeeyayaasha, dahaarka, adkaynta resin epoxy, elastomers polyurethane, iwm.
Waxaa lagu soo buuxiyay 50kg/durbaan, 170kg/durbaan, Muddada kaydinta waa 1 sano.
Tilmaamaha badbaadada:
Kaydintu waa inay ahaataa mid qabow, qalalan oo hawo leh. Xaaladda ugu fiican waa -20 ~ 38℃. Muddada kaydinta waa 12 bilood, haddii ay dhacdo, wali waa la isticmaalaa haddii ay heer caadi ah gaarto iyada oo dib loo tijaabinayo. Marka gaadiidku uu roobka ka fogaado, iftiinka qorraxda. Ha ku qasin oksaydheeye xooggan.
