Tsananguro yeChigadzirwa

TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, CAS nhamba 91-97-4, chinhu chinoshandiswa zvakanyanya pakuvandudza hunhu hwemakanika nemakemikari paurethane elastomers. Mhete mbiri dzebenzene dziri muTODI molecule dzine chimiro chakaenzana. Nekuda kwekusagadzikana kweboka reo-methyl, chiitiko che reaction chakaderera pane cheTDI neMDI.

Zvichienzaniswa neNDI-based polyurethane elastomers, elastomers dzakavakirwa paTODI, oligomer polyols neMOCA dzine hunhu hwakafanana, dzakadai sekudzivirira kupisa, kudzivirira hydrolysis uye hunhu hwemakanika. Zvichienzaniswa nerabha, mapurasitiki nesimbi, TODI-based elastomers dzine zvakanakira zvakawanda, dzakasimba, dzinodzivirira kupisa uye dzinodzivirira hydrolysis. TODI-based elastomers dzine hunhu hwakanaka hwemakanika hunoshandiswa pakushanda mumamiriro ezvinhu akaoma uye/kana nharaunda. Uyezve, nekuda kwehupenyu hwayo hwakareba, TODI-based prepolymer iri nyore kubata kana ichienzaniswa neNDI-based products.

Kushandiswa

Nehunhu hwayo hwakanaka hwemakanika uye makemikari, ma elastomers akavakirwa paTODI anoshandiswa zvakanyanya paminda yakasiyana-siyana. Chekutanga, zvikamu zvekuvhara, zvakaita sekuvharwa kwemafuta, mhete yepiston, zvisimbiso zvemvura nezvimwewo. Zvadaro, zvikamu zvemotokari ndeimwe yekushandiswa kukuru kweTODI, kusanganisira kuwedzera kwebumper, ma shock absorbers, ma grill nezvimwewo. Kunze kwezvo, kushandiswa kwepamusoro-soro mumaindasitiri, kureva mabhandi, ma rolls, ma casters. Uyezve, TODI chinhu chakakosha chekufukidza mumunda wemagetsi uye senhengo dzekugadzira mumidziyo yekurapa.

Kurongedza & Kuchengeta

Kurongedza: 50kgs/dhiramu resimbi.

Kuchengetedzwa uye kutakurwa: TODI inonzwa hunyoro. Mvura inopindirana nema diisocyanates ese kuti igadzire urea derivatives isinganyungudike. TODI inofanira kuchengetwa mumidziyo yakavharwa zvakasimba mumamiriro ezvinhu anotonhorera uye akaoma.

Usaise TODI pamwe chete nechikafu uye usaiise munzvimbo inotonhora kupfuura 30℃. Mushure mekushandisa, chivharo chinofanira kuvharwa nekukasika kana chisina kushanda zvakanaka. Kana yachengetwa zvakanaka, TODI inoshanda kwemwedzi mitanhatu kubva pazuva rayakaunzwa.
