WS2, yomwe imadziwikanso kuti tungsten sulfide ndi imvi, hexagonal system, semiconductor ndi diamagnetic. Iwo ali otsika kwambiri mikangano kokwana (0.03), mkulu kwambiri kuthamanga kukana ndi makutidwe ndi okosijeni kukana (kuwola akuyamba pa 450 ℃ mu mpweya, Ndi oyenera kutentha, kuthamanga, vacuum mkulu, katundu mkulu, liwilo, cheza mkulu, dzimbiri amphamvu, kopitilira muyeso-otsika kutentha ndi zinthu zina zovuta.

Dimeryl DiisocyanateAYI) ndi aliphatic diisocyanate yapadera yomwe ingagwiritsidwe ntchito pokonzekera ma polima okhala ndi mankhwala okhala ndi haidrojeni yogwira. Ndi gulu lalitali lokhala ndi 36-carbon dimer mafuta acid msana.

The epoxidation wa hydroxyl-zinatha polybutadiene (HTPB) kudzera gawo kutengerapo catalysis (PTC) ntchito H2O2 monga okosijeni ndi ammonium tungstate hydrate ndi asidi phosphoric monga cocatalysts anali bwinobwino ikuchitika mu acidic njira / organic zosungunulira awiri gawo sing'anga.

CTBN (Carboxyl-Terminated Butadiene Nitrile) ndi polima yosunthika yomwe yapezeka kuti ikugwiritsidwa ntchito kwambiri popanga zokutira zama epoxy ndi zomatira zogwira ntchito kwambiri. Zinthu zapaderazi zimapereka zinthu zambiri zopindulitsa, zomwe zimapangitsa kukhala chisankho chabwino pamapulogalamu omwe amafunikira kulimba kwapadera, kusinthasintha, komanso kukana mankhwala. Ikaphatikizidwa ndi ma epoxy resins, CTBN imakulitsa magwiridwe antchito onse azomwe zimapangidwira, kuzipanga kukhala zoyenera pazofunikira zosiyanasiyana zamafakitale ndi zamalonda.

HTBN rabara ndi chinthu chosunthika komanso chogwira ntchito kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa cha zinthu zake zapadera. HTBN ndi mtundu wa rabara yamadzimadzi ya nitrile yomwe imakhala ndi magulu ogwira ntchito a hydroxyl kumapeto kwa unyolo wake wa polima, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosiyanasiyana. Nkhaniyi ifufuza momwe HTBN imagwiritsidwira ntchito, katundu, ndi ubwino wa mafakitale osiyanasiyana.

Shanghai Zowonjezera Zatsopano Zatsopano Tech. Co. atsopano opangidwa omangirira othandizira monga HTPB, EHTPB, ATBN, HTBN, CTBN.

Hydrogenated HTPB (Hydrogenated Hydroxyl Group-Terminated Polybutadiene/ Hydrogenated Hydroxyl Terminated Polybutadiene(HTPB) ndi hydrogenated homopolymers wa butadiene,

onse-mathero a hydroxyl gulu-othetsedwa ndi oyenera kugwiritsidwa ntchito kosiyanasiyana. Chifukwa chakuchulukira kwa gulu la 1,2-vinyl ma polybutadienes awa ali ndi kukhazikika kwamankhwala kwakanthawi yayitali.

2,4,7,9-Tetramethyl-5-Decyne-4,7-Diol CAS 126-86-3 surfactant ndi yowonjezera yowonjezera yokhala ndi kunyowetsa, kutulutsa thovu, ndi kufalitsa katundu. Ndi symmetrical non-ionic surfactant yokhala ndi mawonekedwe apadera amitundu iwiri, yomwe imapereka zinthu monga kuchepetsa kugwedezeka kwapamtunda, kuwongolera thovu, ndikuchepetsa kukhudzika kwamadzi.
