WS 2, tseem hu ua tungsten sulfide yog grey, hexagonal system, semiconductor thiab diamagnetic. Nws muaj kev sib txhuam coefficient tsawg heev (0.03), siab kub tsis kam thiab oxidation tsis kam (decomposition pib ntawm 450 ℃ hauv huab cua, Nws yog tsim rau kub, siab siab, siab nqus tsev vacuum, siab load, siab ceev, hluav taws xob siab, muaj zog corrosion, ultra-low kub thiab lwm yam hnyav hnyav.

Dimeryl Diisocyanate (TSIS MUAJ) yog ib qho tshwj xeeb aliphatic diisocyanate uas tuaj yeem siv los npaj cov polymers nrog cov tebchaw uas muaj cov nquag hydrogen. Nws yog cov saw ntev ntev nrog 36-carbon dimer fatty acid qaum.

Lub epoxidation ntawm hydroxyl-terminated polybutadiene (HTPB) ntawm theem hloov catalysis (PTC) siv H2O2 ua cov oxidant thiab ammonium tungstate hydrate thiab phosphoric acid raws li cov cocatalysts tau ua tiav nyob rau hauv ib qho acidic tov / organic hnyav ob-theem nruab nrab.

CTBN (Carboxyl-Terminated Butadiene Nitrile) yog ntau yam polymer uas tau pom dav siv hauv kev tsim cov txheej txheem epoxy thiab cov nplaum ua haujlwm siab. Cov khoom siv tshwj xeeb no muaj ntau yam khoom muaj txiaj ntsig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum muaj qhov tshwj xeeb durability, yooj, thiab tshuaj tiv thaiv. Thaum ua ke nrog epoxy resins, CTBN txhim kho tag nrho cov kev ua tau zoo ntawm cov txiaj ntsig formulations, ua rau lawv haum rau ntau yam kev thov kev lag luam thiab kev lag luam.

HTBN roj hmab yog cov khoom siv ntau yam thiab ua tau zoo siv hauv ntau qhov kev lag luam rau nws cov khoom tshwj xeeb. HTBN yog ib hom kua nitrile roj hmab uas muaj hydroxyl functional pawg nyob rau ntawm qhov kawg ntawm nws cov polymer chains, ua rau nws haum rau ntau yam kev siv. Kab lus no yuav tshawb txog kev siv, khoom, thiab cov txiaj ntsig ntawm HTBN hauv kev lag luam sib txawv.

Shanghai Ntxiv Cov Khoom Siv Tshiab Tech. Co. cov tshiab tsim cov neeg ua haujlwm sib raug zoo li HTPB, EHTPB, ATBN, HTBN, CTBN.

Hydrogenated HTPB (Hydrogenated Hydroxyl Group-Terminated Polybutadiene / Hydrogenated Hydroxyl Terminated Polybutadiene (HTPB) yog hydrogenated homopolymers ntawm butadiene,

lawv yog ob leeg-kawg hydroxyl pawg-tawm thiab tsim nyog rau ntau yam kev siv. Vim lub saturation ntawm 1,2-vinyl pab pawg neeg no polybutadienes muaj zoo heev mus sij hawm ntev tshuaj stability.

2,4,7,9-Tetramethyl-5-Decyne-4,7-Diol CAS 126-86-3 surfactant yog cov khoom siv ntau yam ntxiv nrog ntub dej, defoaming, thiab dispersing zog. Nws yog ib qho symmetrical non-ionic surfactant nrog cov qauv ntxaib tshuaj tshwj xeeb, muab cov yam ntxwv xws li txo qhov nro, tswj ua npuas dej, thiab txo cov dej rhiab heev.
