Polybutadiene da aka dakatar da Hydrogenated HTPB
An yi amfani da hydrogenated HTPB Polybutadiene da aka dakatar da Hydrogenated Hydroxyl Group
Cikakkun bayanai game da samfurin:
Sunan Sinadari: HTPB Mai Hydrogenated
Nau'i: Sigar Hydrogenated
Tsarin:
Harafi: China Mai Fitar da Kaya Mai Izini / Lasisin Fitar da Kaya na HTPB
Ma'auni: GB (Matsayin Jama'a) / GJB (Matsayin Soja/ GJB 1327A-2003)
HTPB wani roba ne mai kama da ruwa mai nisa, sabon robar ruwa. Abubuwan da ke tattare da shi sun bambanta saboda HTPB cakuda ne maimakon tsantsar mahaɗi, kuma an ƙera shi ne don biyan buƙatun abokan ciniki. HTPB na yau da kullun shine R-45M tare da kowane ƙarshen sarkar da aka ƙare da rukunin hydroxyl [OH].PS: za mu iya yin kowace sigar HTPB kamar yadda abokan ciniki suka buƙata, kuma za mu iya ƙirƙirar HTPB tare da sarkar hydroxyl -OH guda ɗaya, A halin yanzu, za mu iya yin hydrogenation na HTPB)
Ga HTPB, nau'ikan butadiene ne masu hydrogenated, waɗanda aka dakatar da su daga rukunin hydroxyl kuma sun dace da amfani iri-iri. Saboda cikar rukunin 1,2-vinyl, waɗannan polybutadienes suna da kyakkyawan kwanciyar hankali na sinadarai na dogon lokaci.
Kadarorin kamar:
Tsarin da yake da sassauƙa sosai
Tsananin Hydrophobic
Ƙananan ma'aunin dielectric
Kyakkyawan juriya ga sinadarai
Rukunin hydroxyl masu amsawa
Kwanciyar hankali na dogon lokaci
Masu gyaran resin, resin urethane (fenti, manne, wakilin rufi), kayan rufe wutar lantarki, elastomers na TPU
shiryawa:
An saka a cikin 50kg/ganga, 170kg/ganga, Lokacin ajiya shine shekara 1.
Umarnin tsaro:
Ya kamata a ajiye a wuri mai sanyi, bushe kuma a bar iska ta shiga. Mafi kyawun yanayi shine tsakanin -20 ~ 38℃. Tsawon lokacin ajiyar shine watanni 12, idan ya ƙare, har yanzu ana amfani da shi idan ya dace da ƙa'ida ta hanyar sake gwadawa. Idan sufuri ya kamata a guji ruwan sama, a guji hasken rana. Kar a haɗa shi da mai ƙarfi na oxidizing.
