IMIQATHANGO YOKUSEBENZA (Umatshini wokutsala umtshini)

• Preheat isocyanate ukuya kuma-23 - 30°C kwimeko yokugcinwa ngaphantsi kwe-20°C.

• Preheat polyol kunye nenxalenye C ukuya kuma-40°C phambi kokuba uyisebenzise.Kuyimfuneko ukuvuselela i-polyol de zombini umbala kunye nembonakalo ibe yinto efanayo.

• Ukulinganisa amacandelo ngokomlinganiselo wokuxuba, faka isocyanate kwikomityi ephezulu, yongeza inxalenye C kwi-polyol kwi-premix.

• Galela i-isocyanate kwi-polyol (equlathe iSahlulo C) kwaye uxube isithuba semizuzu emi-1 ukuya kwemi-2 emva kokukhupha umoya kangangemizuzu eli-10 ngokwahlukeneyo.

• Gcoba ngaphantsi kwevacuum kwi-silicone yokungunda efudunyezwe ukuya kuma-70°C.

• Idiza emva kwemizuzu engama-60 ukuya kuma-90 kwi-70°C (Okukhona iCandelo C lisetyenziswa, kokukhona kufuneka ixesha elide lokudiliza).

Ukuphatha imiGaqo

Izithintelo zempilo kunye nokhuseleko eziqhelekileyo kufuneka ziqwalaselwe xa uphethe ezi mveliso :

Qinisekisa ukungena komoya kakuhle

Nxiba iiglavu, iiglasi zokhuseleko kunye nempahla yokukhusela.

Ngolwazi oluthe vetshe, nceda uqhagamshelane nephepha ledatha yokhuseleko lwemveliso.

Iimeko zokuGcina

Ubomi beshelufu ziinyanga ezi-6 kwindawo eyomileyo kwaye kwizikhongozeli zokuqala ezingavulwanga kubushushu obuphakathi kwe-15 kunye ne-25° C. Nayiphi na inkonkxa evulekileyo kufuneka ivalwe ngokuqinileyo phantsi kwengubo eyomileyo yenitrogen.
