Ana samar da rufin polyurethane ta hanyar amsawar da ke tsakanin polyols da isocyanates, sau da yawa a gaban ƙarin abubuwa kamar su abubuwan narkewa, abubuwan cikawa, launuka, da abubuwan da ke warkarwa. Ba tare da wani abu mai kara kuzari ba, wannan amsawar za ta ci gaba a hankali, wanda zai haifar da rashin cikakkiyar warkarwa, rashin kyawun samuwar fim, da kuma raunin halayen injiniya.
Masu haɓaka polyurethanetaka muhimmiyar rawa a cikin:
- Sarrafa yawan amsawa: Tabbatar da daidaito tsakanin tsawon lokacin tukunya (lokacin aiki) da saurin warkewa.
- Inganta daidaiton fim: Taimakawa wajen cimma kammala saman da ya yi laushi tare da tauri mai dorewa.
- Inganta mannewa: Inganta haɗin gwiwa tsakanin shafi da substrate.

- Masu haɓaka Amine
- Haɓaka amsawar urethane (polyol-isocyanate) da urea (isocyanate-ruwa).
- Samar da sassauci wajen sarrafa saurin warkarwa da kuma samuwar fim.
- Misalan sun haɗa da magungunan thier amines kamar BDMA, DMEA, da BDMAEE.
- Masu ƙara ƙarfin ƙarfe
- Yawanci mahaɗan organotin kamardibutyltin dilaurate (DBTDL).
- Samar da aikin gelling mai ƙarfi, yana tabbatar da tauri da ƙarfin injiniya.
- Ana amfani da shi a cikin rufin polyurethane mai ƙarfi wanda ke buƙatar lokaci mai sauri ba tare da mannewa ba.

Ga fenti na masana'antu (misali, na mota, bene), tsaftacewa da sauri da kuma juriya ga sinadarai suna da matuƙar muhimmanci. Ga fenti na itace ko na ado, ana iya ba da fifiko ga ƙirƙirar fim mai santsi da sassauci.
4. Fa'idodin Amfani da Polyurethane Catalysts a cikin Rufi
Ta hanyar amfani da tsarin mai kara kuzari mai kyau, masana'antun shafa shafi za su iya cimma:
- Busarwa da sauri da kuma yawan aiki mai yawa.
- Ingantaccen mannewa ga ƙarfe, robobi, da itace.
- Ƙarfin injina da juriya ga yanayi mai ƙarfi.
- Ƙarin sassaucin ƙira wajen tsara rufin shafi ga masana'antu daban-daban.

TheKa'idojin amfani da polyurethane catalysts a cikin masana'antar rufimai da hankali kan daidaita saurin warkarwa, halayen fim, da kuma bin ƙa'idodin muhalli na zamani. Ta hanyar zaɓar da inganta abubuwan da ke haifar da sinadarai, masana'antun za su iya samar da rufin polyurethane mai inganci tare da kyakkyawan juriya, juriya ga sinadarai, da kuma kyawun gani.
