Tolidine diisocyanate TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate CAS NO. 91-97-4
TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, lambar CAS 91-97-4, ƙari ne na duniya don inganta kayan aikin injiniya da sinadarai akan elastomer urethane. Zoben benzene guda biyu a cikin kwayoyin TODI suna da tsari mai ma'ana. Saboda tsangwama na ƙungiyar o-methyl, aikin amsawa ya kasance ƙasa da na TDI da MDI.
Kwatanta da NDI-tushen polyurethane elastomers, elastomers bisa TODI, oligomer polyols da MOCA suna da irin wannan kaddarorin jiki, irin su kyakkyawan juriya na zafi, juriya na hydrolysis da kaddarorin inji. Kwatanta tare da rubbers, robobi da karafa, TODI-tushen elastomers suna da fa'idodi da yawa, suna da dorewa, juriya na zafi da juriya na hydrolysis. Abubuwan elastomers na tushen TODI suna ba da ingantattun kaddarorin injina don amfani da su akan aiki a ƙarƙashin yanayi mai tsauri da/ko yanayi. Bugu da ƙari, sakamakon tsawon rayuwar tukunyar sa, tushen prepolymer na TODI ya fi sauƙi don ɗauka idan aka kwatanta da samfuran tushen NDI.
Tare da fitattun kayan aikin injiniya da sinadarai, ana amfani da elastomers na tushen TODI akan fannoni daban-daban. Da farko dai, abubuwan da aka haɗa, kamar su rufe mai, zoben piston, hatimin ruwa da sauransu. Sa'an nan, mota sassa wani babban aikace-aikace na TODI, ciki har da m kari, shock absorbers, gasas da sauransu. Bayan, high-karshen masana'antu amfani, watau belts, Rolls, casters. Bugu da ƙari kuma, TODI wani muhimmin shafi ne mai mahimmanci a filin lantarki kuma a matsayin gabobin wucin gadi a cikin kayan aikin likita.
Shiryawa: 50kgs / ganga na ƙarfe.
Adana da sufuri: TODI yana kula da danshi. Ruwa yana amsawa tare da duk diisocyanates don samar da abubuwan urea marasa narkewa. Ya kamata a adana TODI a cikin kwantena da aka rufe sosai a cikin yanayin sanyi da bushewa.
KAR KA sanya TODI tare da abinci kuma ka guje wa fallasa a cikin yanayi sama da 30 ℃. Bayan amfani, dole ne a rufe murfin nan da nan idan akwai rashin aiki. Ƙarƙashin yanayin ajiya da ya dace, TODI yana aiki na tsawon watanni shida aƙalla tare da tasiri daga ranar da aka kawo shi.
