Donpipe 302 HCFC-141b te whakakotahi i nga polyols turanga mo te whakamahana paipa
WHAKATOKANGA
Ko tenei hua he momo polyols whakakotahi i mua i te whakaranu ki te HCFC-141B, he mea rangahau motuhake mo te PUF pakari hei whakaputa i nga paipa whakamahana waiariki.Kei te whakamahia whānuitia i roto i nga putorino mamaoa, nga putorino hau rere, nga putorino hinu me etahi atu mara.Ko nga ahuatanga e whai ake nei:
(1) pai te rere, na roto i te whakarite i te ture kia rite ki nga diameters paipa rereke.
(2) tino pai te whakapumautanga o te taha pāmahana iti
