Hydrogenated HTPB Hydrogenated Hydroxyl Group-Terminated Polybutadiene

Kufotokozera Kwachidule:

HTTPB ndi polima yamadzimadzi yochokera kutali, rabara yatsopano yamadzimadzi. Kapangidwe kake kamasiyana chifukwa HTPB ndi chisakanizo osati chopangidwa mwangwiro, ndipo chimapangidwa kuti chikwaniritse zofunikira za makasitomala. HTPB yachizolowezi ndi R-45M ndipo malekezero onse a unyolo amathetsedwa ndi gulu la hydroxyl [OH]. (PS: tikhoza kupanga kapangidwe katsopano ngati HTPB yokhala ndi -OH imodzi pa unyolo uliwonse ndi mtundu wa Hydrogenated).

Mawonekedwe

HTPB ndi polima yamadzimadzi yochokera kutali, rabara yatsopano yamadzimadzi. Kapangidwe kake kamasiyana chifukwa HTPB ndi chisakanizo osati chopangidwa mwangwiro, ndipo chimapangidwa kuti chikwaniritse zofunikira za makasitomala. HTPB yachizolowezi ndi R-45M ndipo malekezero onse a unyolo amathetsedwa ndi gulu la hydroxyl [OH].PS: tikhoza kuchita mtundu uliwonse wa HTPB monga momwe makasitomala amafunira, ndipo timapanga HTPB yatsopano ndi unyolo umodzi wa hydroxyl -OH, Pakadali pano, tikhoza kuchita hydrogenation ya HTPB)

Kwa Hydrogenated HTPB ndi ma homopolymers a butadiene omwe ali ndi hydrogenated, onse ali ndi hydroxyl group-end-stop ndipo ndi oyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Chifukwa cha kuchuluka kwa 1,2-vinyl group, ma polybutadiene awa ali ndi kukhazikika kwa mankhwala kwa nthawi yayitali.

Mapulogalamu

Zosintha za resin, urethane resins (utoto, zomatira, zophikira), zipangizo zamagetsi zotetezera kutentha, TPU elastomers

Kulongedza ndi Kusunga

Kulongedza:

Yopakidwa mu 50kg/ng'oma, 170kg/ng'oma, Nthawi yosungira ndi chaka chimodzi.

Malangizo achitetezo:

Kusungirako kuyenera kukhala kozizira, kouma komanso kopatsa mpweya wabwino. Malo abwino kwambiri ndi pakati pa -20 ~ 38℃. Nthawi yosungiramo zinthu ndi miyezi 12, ngati yatha, ingagwiritsidwenso ntchito ngati ili yoyenera nthawi zonse poyesanso. Mukayendetsa, samalani kupewa mvula, kuwala kwa dzuwa. Musasakanize ndi chotenthetsera champhamvu.
