1. Umgababo okuqinileyo kwezilungu.
(1) i-Polyether polyols: umgabano okupheleleyo lwe-ethylene oxide, umnotho omkhulu, ufikisele ngokubani xa kuziphindaphinda amagama akhothi a-Polyether polyols nge-activities ezidingekayo.
(2) Isimo sokuqhathanisa: inani elikhulu lezi-Zinc octanoate, umnotho omkhulu we-isocyanate, umnotho omkhulu wex-linking, usheduli esikhathini sokuxhambuka, amine nokuba aphofo amanani ephakathi.
Ngokugcineni, umoya wemfomfo ubukhulu, emfomfo ayiqhanyisanga xa umoya wesithuthuko lokubukeka, kunye nekuqinileyo kakhulu kwesithuthuko sengxelo xa i-TDI index ifanele kakhulu.
2. Ukususwa (umnotho wesilinganiso ukufuneka kulula kakhulu kancinci kokuxhambuka).
(1) Umnotho omkhulu wokuqinileyo kunye nekususwa ngelinye ilimi lokulandela.
(2) Amazwelonqubo ezinhloko zokusebenza: umoya wentsha okuntsha kunye nemvume yamanye amanani okuntsha.
(3) Isimo sokuqhathanisa: isilawu sesilawu esikhulu, amanye amanani aphofo esikhulu, i-TDI index efanele kakhulu.
3. Ukususwa kwindawo.
(1) Amazwelonqubo ezinhloko zokusebenza: umoya wentsha efanele kakhulu kunye nomtembeliso womoya wesentlo omtshato.
(2) ifomula yemfundo: isiliso sokuqala se-TDI esincinci, umsebenzi wesi-tin ehulu kwaye ungenzi lokulayishwa oluhulu ngaphambi kokukhona.
(3) amafu asesayithini aluhlaza okubanzi kunye nokusetyenziswa esincinci.
4. Umthombo wokungabeka (uvimba lwe-aerogel aluhlazekile).
(1) izicwangciso zokusebenza: umthi wesikhephe esincinci kunye nomphilo wesintshontshi esincinci.
(2) ifomula yemfundo: usuku lwencane lolwazi lwamakholisi, usuku lwencane lwe-amine, kwaye amafu asesayithini aluhlazekile.
5. Icrack yebhedi elindelini (kune-amine ngaphezulu, uvimba lukhona ngqukuqaleni lokulayishwa).
Amahole angasemva: usuku lwencane lolwazi lwesayithini fowethengiselwa, kwaye amafu asesayithini aluhlazekile kunye namakholisi.
6. Ukusebenza kakhulu kwemfomolo ngumthi omncinci.
Ukuphakamiselo kwe-polyether polyol kukhona nge-NDI esincinci ngale ndawo lesi-hydroxide, usuku lwencane lokufundiswa, umsebenzi wesi-tin ehulu kunye nokuthi umsebenzi wesi-tin esincinci.
7. Ukugcwalisa kakhuli kwaye ukwenqaniswa.
(1) Iindlela zomgciwano: umoya omncane.
(2) Amagama amantsho: ipolieti yepoliloli elingqangi, umkhwezi wesilawoni elingqangi.
(3) Ifomula yesiphumo: kakhulu itini, noma isebenzisa ngale nombolo wotini, umoya omncane kunye nokulandelana neamine, ifakti le-TDI elilingqangi.
8. Ukufakwa kokungapheli kwindlela engenayo.
(1) Amagama amantsho: ipolieti yepoliloli uma uyingqangi, umndeni womolekulo omncane kunye nomkhwezi wesilawoni elingqangi.
(2) Ifomula yesiphumo: inani lesilawoni elilingqangi, kakhulu itini, kakhulu umoya kunye nokuthi ifakti le-TDI elilingqangi ngale nombolo wotini.
