HydrogenatedHTPBHydrogenated Hydroxyl Group-Tsarin Polybutadiene
Bayanin samfur:
Sunan Sinadari: Hydrogenated HTPB
Nau'in: Tsarin hydrogenated
Formula:
Hali: Lasisin fitarwa na China mai izini / HTPB
Ma'auni: GB (Grejin farar hula) / GJB (Mai Girman Soja/ GJB 1327A-2003)
HTPB ruwa ne mai nisa kambori polymer, sabon roba ruwa. Kaddarorin sun bambanta saboda HTPB cakuɗe ne maimakon fili mai tsafta, kuma an ƙera shi don biyan takamaiman bukatun abokan ciniki. HTPB na yau da kullun shine R-45M tare da kowane ƙarshen sarkar da aka ƙare tare da ƙungiyar hydroxyl [OH]. (PS: za mu iya yin kowane nau'i na HTPB kamar yadda abokan ciniki suka buƙaci, da kuma sabon zane da HTPB tare da sarkar hydroxyl -OH guda ɗaya, A halin yanzu, za mu iya yin hydrogenation na HTPB.)
Domin Hydrogenated HTPB ne hydrogenated homopolymers na butadiene, su biyu-karshen hydroxyl kungiyar-kare kuma dace da fadi da kewayon amfani. Saboda jikewa na rukunin 1,2-vinyl waɗannan polybutadiene suna da ingantaccen kwanciyar hankali na dogon lokaci.
Kayayyaki kamar:
Tsarin sassauƙa sosai
Hydrophobicity
Low dielectric akai
Kyakkyawan juriya na sinadarai
Ƙungiyoyin hydroxyl masu amsawa
Dogon kwanciyar hankali
Resin modifiers, urethane resins (Paints, adhesives, shafi jamiái), lantarki insulating kayan, TPU elastomers
Shiryawa:
Kunshe a cikin 50kg / drum, 170kg / drum, Lokacin ajiya shine shekara 1.
Umarnin aminci:
Ma'aji ya kamata ya kasance a sanyi, bushe da iska. Mafi kyawun yanayin shine tsakanin -20 ~ 38 ℃. Rayuwar tanadin watanni 12, idan ya ƙare, har yanzu ana amfani da ita idan har ta kai ta hanyar sake gwadawa. Lokacin da sufuri ya kamata ya guje wa ruwan sama, hasken rana. Kada ku haɗu da mai ƙarfi oxidizer.
