Described blowing agent is HCFC-141b.
Horizontal type foaming raw material reaction climb altitude reduces, but there are certain requirements raw material lateral flow, therefore compared with vertical-foaming, need carry out great many of experiments adjustment to foaming raw material combined polyether formula, and obtains low-density formula everywhere.
The invention has the beneficial effects as follows: adopt this horizontal type foaming technique and raw material, technological design advantages of simple, easily processing, easy to operate.Water tank heat-insulation layers Density Distribution is even, and heat insulation effect improves; Water tank and outer courage keep better with one heart, and the outer courage of water tank occurs without problems such as cracking, quick-fried buckets; Special polyethers lateral flow is good, and foam density is low, and abscess is evenly fine and closely woven, and tired bubble is few.The reduction of foam-filled amount can reduce the material cost of 15% ~ 20%, and production efficiency improves 20% ~ 30%.
It is 24 ~ 26kg/m that the horizontal type foaming of this invention freely steeps density by hand
3, the average core density of casing is 32 ~ 36kg/m
3.The foaming of tradition one rifle high pressure vertical, freely steeping density is 27 ~ 35/m
3, the average core density of casing is 35 ~ 45kg/m
