Izakhiwo ze-physicochemical: okumhlophe kuya kokuphuzi okukhanyayo okuqinile okucwebezelayo okusakristalu. Iphuzu lokuncibilika: 126-130 °C, iphuzu lokubila: 167 °C (5 × 1.33kPa), ukuminyana: 1.42-1.45g/cm3
I-1,5-naphthalene diisocyanate (NDI) uhlobo lwe-polyurethane (PU) eyenziwe yi-diisocyanate. Uma iqhathaniswa ne-MDI ne-TDI, i-NDI enephuzu lokuncibilika eliphakeme, ukuqina okuphezulu kwama-molecule, ukuhleleka, kanye nokulingana, okungathuthukisa ngokuyisisekelo izinga lokuhlukaniswa kwesigaba se-polyurethane, okwenza i-polyurethane esekelwe ku-NDI ithole izakhiwo ezinhle kakhulu zemishini nezomzimba. I-polyurethane esekelwe ku-NDI inokumelana okuphezulu kokuguguleka, ukumelana okuphezulu kokushisa, ukumelana nokugqwala kanye nezakhiwo ezinhle kakhulu ze-dynamic, futhi isetshenziswa kakhulu ezikhathini zomthwalo ophezulu we-dynamic kanye nokumelana nokushisa.
I-NDI (1,5-Naphthalene Diisocyanate) iyinto eluhlaza eyenziwe nge-polyurethane ethuthukisiwe, engasetshenziswa ukukhiqiza i-polyurethane elastomer enokuqina okuphezulu kanye nobunzima obuphezulu. I-NDI polyurethane elastomer isebenza kahle kakhulu. Isebenza kahle kakhulu kunanoma iyiphi enye i-polyurethane elastomer, njengokusebenza okuhle kakhulu okuguquguqukayo, ukusebenza okuphezulu kakhulu kwemishini, ukumelana okuhle kakhulu kokusika, ukumelana nokuguguleka kanye nokumelana nokushisa. Ngakho-ke, ama-NDI polyurethane elastomer asetshenziswa kabanzi kuma-absorber shock absorber ezimoto, amasondo okuthwala ama-forklift, ukuphrinta nokudaya ama-roller erabha yendwangu, ama-raber scraper, ama-buffer block okwakhiwa kwamabhuloho, imboni yezempi, njll.
I-elastomer ephothwayo eyenziwe yi-NDI inezici ezinhle kakhulu eziguquguqukayo kanye nokumelana nokuguguleka, futhi inomswakama omncane, ukumelana okuphezulu, kanye nokushisa okuncane kwangaphakathi. Ingasetshenziswa ezimweni zomthwalo oguquguqukayo kanye nokumelana nokushisa okuphezulu. Imikhiqizo ebunjiwe eyenziwe nge-NDI inamandla amakhulu okudabuka, ukuguguleka okuphansi, isethi yokucindezela okuphansi kanye nokumelana okuhle kakhulu. Imikhiqizo ye-elastomer ye-polyurethane e-microporous esekelwe kwi-NDI inokushisa okuphansi okungokwemvelo, ukuguqulwa okuncane okuhlala njalo kanye nokuqina okuhle ngaphansi komthwalo oguquguqukayo. Le nto ekhethekile ye-polyurethane e-microporous isetshenziselwa kakhulu ukumuncwa kwezimoto kanye nezingxenye zokusika.
Singumdlali obalulekile emakethe ye-NDI. Umthamo wethu wokukhiqiza we-NDI ungama-500 MT ngonyaka futhi uyaqhubeka nokukhula.
Ukupakisha: 20kgs/isigubhu sensimbi; 40kgs/isigubhu sensimbi; 600kgs/isikhwama
Ukugcina Nokuthutha: Gcina Endlini Epholile Neyomile. Ukuvikela Emithonjeni Yomlilo Neyokushisa
