IMIBANDELA YOKUQHUBEKA (Umshini wokukhipha i-vacuum)
• Shisisa i-isocyanate ibe ngu-23 - 30°C uma igcinwa ngaphansi kuka-20°C.
• Shisisa i-polyol nengxenye C kuye ku-40°C ngaphambi kokuyisebenzisa.Kuyadingeka ukunyakazisa i-polyol kuze kube yilapho kokubili umbala nesici silingana.
• Kala izingxenye ngokwesilinganiso sokuxuba, faka i-isocyanate enkomishini engaphezulu, engeza ingxenye C ku-polyol ku-premix.
• Thela i-isocyanate ku-polyol (equkethe Ingxenye C) bese uxuba imizuzu engu-1 - 2 ngemva kokukhipha umoya imizuzu eyi-10 ngokuhlukana.
• Faka ngaphansi kwe-vacuum kusikhunta se-silicone esishiswe kuqala sibe ngu-70°C.
• Khipha ngemva kwemizuzu engama-60 - 90 ku-70°C (Uma kusetshenziswa Ingxenye C, kudingeka isikhathi eside sokudiliza).

Ukuphatha Izinyathelo Zokuqapha
Izinyathelo zokuphepha ezijwayelekile kufanele zibhekwe lapho uphatha le mikhiqizo :
Qinisekisa umoya omuhle
Gqoka amagilavu, izibuko zokuphepha nezingubo zokuzivikela.
Ukuze uthole ulwazi olwengeziwe, sicela ubheke ishidi ledatha yokuphepha komkhiqizo.
Izimo Zokugcina
Isikhathi seshelufu siyizinyanga eziyisi-6 endaweni eyomile futhi ezitsheni ezingavulwanga zokuqala ezingeni lokushisa eliphakathi kuka-15 no-25° C. Noma iyiphi ithini evulekile kufanele ivalwe ngokuqinile ngaphansi kwengubo eyomile yenitrogen.
