Tolidine diisocyanate TODI / 3,3′-Dimethyl-4,4′-biphenylene diisocyanate CAS NO. 91-97-4
TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, nhamba yeCAS 91-97-4, inowedzera yepasi rose yekuvandudza ma mechanical uye makemikari zvinhu pa urethane elastomers. Mhete mbiri dze benzene dziri mu TODI molecule dzine symmetrical structure. Nekuda kwekuvhiringidza kweiyo o-methyl boka, kuita kwekuita kwakadzikira pane kweTDI neMDI.
Tichienzanisa neNDI-based polyurethane elastomers, elastomers yakavakirwa paTODI, oligomer polyols uye MOCA zvine maitiro akafanana emuviri, akadai seakanakisa kupisa kupisa, hydrolysis kuramba uye michina zvinhu. Kuenzanisa nerabha, mapurasitiki nesimbi, TODI-based elastomers ine zvakawanda zvakanakira, inogara yakasimba, inodzivirira kupisa uye hydrolysis kuramba. TODI-based elastomers inopa epamusoro mechanicha zvivakwa kuti zvishandiswe pakushanda pasi pemamiriro akaoma uye / kana nharaunda. Uyezve, zvichibva pahupenyu hwayo hurefu hwepoto, TODI-based prepolymer iri nyore kubata mukuenzanisa neNDI-based products.
Neayo akatanhamara emuchina uye makemikari zvivakwa, TODI-based elastomers inoshandiswa zvakanyanya pandima dzakasiyana. Chokutanga pane zvose, kuisa chisimbiso, zvakadai sekuisa chisimbiso chemafuta, piston mhete, zvisimbiso zvemvura uye zvichingodaro. Zvadaro, zvikamu zvemotokari ndezvimwe zvekushandisa kukuru kweTODI, kusanganisira kuwedzera kwebumper, shock absorbers, grills uye nezvimwe. Kunze kwezvo, kushandiswa kwepamusoro-soro kwemaindasitiri, kureva mabhanhire, rolls, casters. Uyezve, TODI chinhu chakakosha chekuputira mumunda wemagetsi uye senhengo dzekugadzira mumidziyo yekurapa.
Kurongedza: 50kgs / iron dhiramu.
Kuchengeta uye chekufambisa: TODI inonzwa kune unyoro. Mvura inopindirana neese diisocyanates kuti igadzire zvisinganyunguriki urea zvinobva. TODI inofanira kuchengetwa mumidziyo yakavharwa zvakasimba munzvimbo inotonhorera uye yakaoma.
Usaise TODI pamwe nechikafu uye dzivirira kufumura munzvimbo iri pamusoro pe30 ℃. Mushure mekushandisa, chivharo chinofanira kuvharwa nekukurumidza kana paine kusashanda. Pasi pemamiriro ekuchengetedza akakodzera, TODI inoshanda kwemwedzi mitanhatu ingangoita kubva pazuva rainounzwa.
