Phenolic Resin for Exterior Insulation Board

Kufotokozera Kwachidule:

Utoto umagwiritsa ntchito ukadaulo wa melamine ndi resorcinol wosintha kawiri kuti uwongolere mawonekedwe apamwamba a ortho ndi kuchuluka kwa methylol phenolic resin, ndikupanga utomoni wa phenolic wokhala ndi thovu lofanana ndi thovu la polyurethane.Utoto umakhala pa kutentha kwina.Kutulutsa thovu kumakhalanso ndi nthawi yodziwikiratu emulsification, nthawi yotuluka thovu, nthawi ya gel, komanso nthawi yochiritsa.Zakwaniritsa kusintha kwakukulu pakupanga chithovu, ndipo zitha kugwiritsidwa ntchito popanga matabwa opitilira thovu a phenolic.The thovu opangidwa ali ndi ubwino wabwino dimensional bata, thovu zabwino ndi otsika matenthedwe madutsidwe.
