Hydroxyl Terminated Polybutadiene
ʻO ka Hydroxyl-terminated polybutadiene (HTPB) he ʻano o ka ʻili wai me ke kaumaha molekala like ʻole (ma kahi o 1500-10,000 g/mol) a me kahi kiʻekiʻe o ka hana reactive.Loaʻa i ka ʻōpala wai kahi hui kūʻokoʻa o nā waiwai e like me ke aniani hoʻololi haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe ka hoʻouka paʻa, a me ka hiki ke kahe maikaʻi.Ua hoʻohana nui ʻia lākou i nā adhesives, coatings, sealants, lāʻau lapaʻau, a me nā mea ikaika.
He wai translucent ka HTPB me ke kala e like me ka pepa wax a me ka viscosity like me ka syrup kulina.ʻOkoʻa nā waiwai no ka mea he hui ʻia ʻo HTPB ma mua o kahi hui maʻemaʻe, a ua hana ʻia ia e hoʻokō i nā koi kikoʻī o nā mea kūʻai aku.

Nā memo
1) ʻO nā ʻikepili ʻenehana āpau i hōʻike ʻia ma luna nei no kāu kuhikuhi.
2) Hoʻokipa ʻia nā kikoʻī ʻē aʻe no ke kūkākūkā hou aku.
4. Hoʻohana: Hoʻohana nui ʻia ʻo HTPB i nā ʻano kaʻa a pau me ka propellant kemika paʻa i ka mokulele a me ka lele mokulele, ka pauda adhesive, no ka hoʻohana kīwila, hiki ke hoʻohana ʻia i nā kula me nā huahana PU, hoʻolei i nā huahana elastomer, pena, uila. nā mea hoʻopaʻa i hoʻopaʻa ʻia etc.
5. Net kaumaha 170kg i 200 liters polyethylenelined metala pahu.
Hoʻopilikino
Loaʻa ka hana hana maʻamau no nā noi like ʻole e pili ana i kāu koi ʻenehana.
Loaʻa iā mākou ka ʻike R&D, a me ka ʻoihana hana, hiki ke hoʻomohala a hoʻāʻo-hana i nā mea hou a me nā kikoʻī e like me ke koi kikoʻī.
