Ukuqalisa

I-DonSPray504 i-Spray Blend Polyols, i-ejenti evuthayo iyi-245fa esikhundleni se-HCFC-141B, iphendulela nge-isocyanate ukukhiqiza i-foam eyenziwe kahle kakhulu, okulandelayo, okulandelayo,

1) amaseli amahle futhi alingana

2) Ukuvuselelwa okuphansi okushisayo

3) Ukumelana nelangabi eliphelele

4) Ukuqina okuhle kobukhulu obuphansi.

Isebenza kuzo zonke izinhlobo zobunjiniyela bokufakwa kwe-thermal okusebenzisa ubuchwepheshe besifutho, njengamagumbi abandayo, amabhodwe, amapayipi amakhulu kanye ne-metope yokwakha njll.
