Imikhiqizo
I-Hydroxyl Terminated Polybutadiene
I-Hydroxyl-terminated polybutadiene (HTPB) iwuhlobo lwenjoloba ewuketshezi enesisindo esihlukile samangqamuzana (cishe i-1500–10,000 g/mol) kanye nezinga eliphezulu lokusebenza okusabelayo.Irabha ewuketshezi inenhlanganisela eyingqayizivele yezakhiwo ezihlanganisa izinga lokushisa eliphansi lokushintsha kwengilazi, ukuguquguquka kwezinga lokushisa eliphansi, umthamo omkhulu wokulayisha okuqinile, nekhono elihle lokugeleza.Zisetshenziswe kakhulu kuma-adhesives, okokugqoka, ama-sealants, imithi, kanye nezinto ezisebenzayo.
I-HTPB iwuketshezi olushintshashintshayo olunombala ofana nephepha le-wax kanye ne-viscosity efana nesiraphu yommbila.Izakhiwo ziyahlukahluka ngenxa yokuthi i-HTPB iyingxube kunenhlanganisela emsulwa, futhi ikhiqizwa ukuze ihlangabezane nezidingo eziqondile zamakhasimende.
1. UKUBUKEKA:Uketshezi olungenambala noma oluphuzi olusobala

Amanothi
1) yonke idatha yobuchwepheshe eboniswe ngenhla ingeyereferensi yakho.
2) okunye ukucaciswa kwamukelekile ukuze kuxoxiswane kabanzi.
4. Ukusetshenziswa: I-HTPB isetshenziswa kabanzi kulo lonke uhlobo lwenjini enamakhemikhali aqinile endizeni endizeni nasemkhathini, okunamathelisa isibhamu, futhi kusetshenziselwe umphakathi, ingasetshenziswa emasimini okuhlanganisa imikhiqizo ye-PU, imikhiqizo yokusakazwa kwe-elastomer, upende, ugesi. izinto zokuvala ama-insulated sealant njll.
5. Isisindo seNet 170kg ku-200 litre polyethylenelined metal drum.
Ukwenza ngokwezifiso
Ukukhiqiza okwenziwe ngendlela oyifisayo kuyatholakala ukuze kusetshenziswe izinhlelo ezihlukahlukene ngokusekelwe kwimfuneko yakho yobuchwepheshe.
Sine-R&D ecebile enesipiliyoni, kanye nomnyango wokukhiqiza, okwazi ukuthuthukisa kanye nokukhiqiza izinto ezintsha nezicaciso ngokwezidingo ezithile.
