PTSI p-toluenesulfonyl isocyanate CAS 4083-64-1 Tosyl isocyanate
MSI (PTSI), p-toluenesulfonyl isocyanate, monoisocyanate ikoreshwa cyane, ikintu gikunze gukoreshwa cyane nk'ikintu gikuraho amazi mu bicuruzwa bya shimi, nk'ibintu bisukura, ibyuzuza, irangi n'ahantu hakozwe muri tar. Kubera ko ari ikintu gikuraho amazi mu bikoresho bya polyurethane (PU) bishingiye ku bisukura, ibifunga, kole ndetse n'igice cy'ibinyabutabire bitandukanye by'ingenzi mu nganda.
P-toluenesulfonyl isocyanate (PTSI) irinda ingaruka mbi ku irangi no gusiga irangi, bityo, ituma abakora ifuru bakora polyurethane nziza. Mu gukoresha PTSI mu gukora irangi rya polyurethane, gutakaza ifuro ry'umukara, umuhondo n'iry'umukara biterwa n'ubuso butose muri sisitemu byose biragabanuka. P-toluenesulfonyl isocyanate ishobora kandi kuba inyongeramusaruro ku bikoresho bigabanya ubushuhe kugira ngo hirindwe kwangirika cyangwa/no guhinduka ibara mu gihe cyo kubika.
MSI (PTSI) igira ingaruka ku mazi, igatanga dioxyde de carbone, bigatuma habaho ibintu bishobora gushonga mu marangi asanzwe. Hafi garama 12 z'umuti utuma ibintu bihinduka ni ngombwa mu gihe ukoresheje garama 1 y'amazi. Icyakora, ubunararibonye bwagaragaje ko ingaruka zirushaho kuba nziza iyo hari MSI (PTSI) nyinshi. Ikoreshwa ry'ibikoresho byo gufunga amarangi rigomba kugeragezwa mbere y'uko ritangira.
Isocyanate ya p-toluenesulfonyl isabwa gukoreshwa nk'umuyoboro uhagarika uruhererekane mu gihe cyo kuyungurura no gukuraho amatsinda y'imikorere adakenewe mu bikoresho fatizo bya PU. Mu irangi rya PU rya tar tar, MSI ishobora gukoreshwa mu kugabanya amine n'amatsinda y'imikorere ya OH no gukuramo amazi muri tar kugira ngo hirindwe ifuro no gushonga imburagihe iyo tar ivanze na PU prepolymer.
Ibiranga:
- Bikuraho ingaruka z'ubushuhe kandi bikarinda ibibazo by'ubushuhe mu irangi rya polyurethane
- Isocyanate ntoya kandi ikora kimwe, ikora imiti ivanze n'amazi, igakora amide idakora neza.
- Ikoreshwa mu kugabanya amazi mu bintu bisukura, ibirungo, ibara n'ibirungo bya bituminous
- Yongera ubushobozi bwo kubika neza diisocyanates mu gihe zidapfa kubora cyangwa ngo zihinduke ibara
- Ikuraho ubushuhe buterwa n'ibintu bisukura, irangi, n'ibindi byuzuza muri sisitemu ya PU ifite ibice bimwe na bibiri
MSI (PTSI) ikoreshwa nk'ikintu gikomeza ubushuhe mu bikoresho bigabanya ubushuhe. Irinda ingaruka mbi ku irangi no gusiga irangi mbere y'igihe. P-toluenesulfonyl isocyanat ikunze gukoreshwa nk'ibi bikurikira:
- Koleti n'ibifunga bya polyurethane by'igice kimwe n'ibice bibiri.
- Gusiga irangi n'amarangi bya polyurethane bifite igice kimwe n'ibice bibiri.
- Ibishongesha
- Amabara
- Ibikoresho byuzuza
- Ibikoresho bitanga umusaruro

Kubika no gutwara: PTSI ntishobora guhumeka ku bushyuhe, bityo igomba kubikwa mu bikoresho by’umwimerere bifunze neza ku bushyuhe buri hagati ya 5°C na 30°C. Iyo imaze gufungurwa, ibikoresho bigomba kongera gufungwa ako kanya nyuma yo gukuraho ibicuruzwa. Bika kure y’inzoga, imisemburo ikomeye, amine, n’ibindi bintu bikomeye bigabanya ubushuhe.
Igihe cyo kubika: Amezi 6 uhereye igihe byakorewe.
