Intengo engcono kakhulu ye-Desmodur RE yezinamathiseli ze-CAS 2422-91-5 Triphenylmethane -4,4`,4"-triisocyanate/ Methylidintri-p-phenylene triisocyanate
I-RE yethu iyi-ejenti yokuxhumanisa esebenza kakhulu, Isetshenziswa ezinamathiselweni ezenziwe nge-hydroxyl polyurethane, irabha yemvelo noma yokwenziwa, inamandla amahle kakhulu okubopha erabha futhi ingasetshenziswa ku-resin, i-antioxidant, i-ejenti yokwenza ipulasitiki, njll. Ingasetshenziswa njenge-crosslinker esikhundleni se-BAYER's Desmodur RE.
Imininingwane yomkhiqizo:
Igama Lekhemikhali: I-Triphenylmethane-4,4',4''-triisocyanate
Ifomula Yamamolekyuli: C22H13N3O3
I-CAS: 2422-91-5
I-MW: 367.36
Uhlamvu: umenzi
Ifomula yesakhiwo: HC[NCO]3
Ubuningi: 1.0g/c m3, 20℃
Indawo yokuncibilika: 89℃
I-RE yethu, ebizwa nangokuthi i-TTI, iyisisombululo esiqukethe i-27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate kanye ne-72.5% ethyl acetate. Iyi-ejenti yokwelapha/i-crosslinker ehlanganisa yonke indawo yokunamathisela esekelwe ku-hydroxyl polyurethane, irabha yemvelo neyokwenziwa, ikakhulukazi enhle kakhulu ezintweni zerabha zokubopha. Iphinde isetshenziswe kabanzi ekuhlanganiseni izinsimbi ngerabha. Ngaphezu kwalokho, i-RE ingasetshenziswa ku-resin, i-antioxidant, i-plasticizer, njll. Ensimini yokunamathisela, i-RE isetshenziswa njenge-ejenti yokuxhumanisa ku-neoprene adhesive kanye/noma ku-p hydroxyl polyurethane adhesive ezindaweni zezicathulo. Ngokuvamile, ukuze kuhlanganiswe i-adhesive izingxenye eziyi-100 ngesisindo (pbw) ngokusekelwe enanini elinconywayo elingu-4-7 pbw RE. Isikhathi sokuphila se-adhesive exubile sicishe sibe amahora.
I-glue enezingxenye ezimbili kumele isetshenziswe phakathi nesikhathi esisebenzayo ngemva kokufaka i-RE. Ubude besikhathi esisebenzayo abuhlobene nje kuphela nokuqukethwe kwe-polymer kwe-glue, kodwa futhi nezinye izingxenye ezifanele (njenge-resin, i-antioxygen, i-plasticizer, i-solvent, njll. Uma iseduze nesikhathi esisebenzayo, ngokuvamile amahora ambalwa noma usuku olulodwa lokusebenza, i-glue iba nzima kakhulu ukuyisebenzisa, futhi i-viscosity iyanda maduze. Ekugcineni, iba i-jelly engenakuguqulwa. I-glue yekhwalithi engu-100, i-Hydroxyl polyurethane (i-Polyurethane ilinganiselwa ku-20%), i-RE dose engu-4-7. I-Chloroprene rubber (i-rubber ilinganiselwa ku-20%), i-RE yethu yenza okungu-4-7.
Ukupakisha:
750g/ibhodlela, amabhodlela angu-20 ebhokisini elilodwa, amabhodlela angu-24 noma angu-30 ephalethini elilodwa;
20kg/isigubhu, izigubhu ezingu-18 noma izigubhu ezingu-27 ephalethini elilodwa;
55kg/isigubhu, izigubhu ezingu-8 noma ezingu-12 ephalethini elilodwa;
180kg/isigubhu, izigubhu ezine kuphalethi elilodwa
Isitoreji:
Sicela ugcine ebhodweni lokuqala elivaliwe ngaphansi kwama-23℃, imikhiqizo ingagcinwa izinzile izinyanga eziyi-12. Izwela kakhulu esikhumbeni; izokhiqiza i-carbon dioxide kanye ne-urea enganyibiliki lapho isabela emanzini. Uma itholakala emoyeni noma ekukhanyeni, izosheshisa izinguquko zombala, kodwa umsebenzi osebenzayo ngeke uthinteke.
