style="text-indent:25px">低溫發(fā)泡劑從眾多可選用的化學(xué)發(fā)泡劑中進(jìn)行選擇，主要應(yīng)考慮的問題是：發(fā)泡劑的分解溫度應(yīng)與塑料的加工溫度相適應(yīng)。有兩種有機(jī)化學(xué)發(fā)泡劑已為低溫聚氯乙烯、低密度聚乙烯和某些環(huán)氧所普遍接受。第1種是甲苯磺酰肼（TSH）。這是一種乳黃色粉末，分解溫度為240°F左右。每克約產(chǎn)生115cc氮?dú)夂鸵恍┧帧５诙N是氧化雙（苯磺酷）肋，或稱OBSH。這種發(fā)泡劑或許在低溫用途中使用更為普遍，這種材料為白色細(xì)粉狀，其正常分解溫度是320°F。如果采用活化劑，如尿素或三乙醇胺，則可將這一溫度下降到265°F左右。每克可放出125cc氣體，主要是氮?dú)?。OBSH分解后的固體產(chǎn)物是聚合物，如果它與TSH共同使用，則可減輕臭味。物理發(fā)泡劑分為三類：①壓縮氣體；②可溶性固體：③在沸點(diǎn)低于0℃的揮發(fā)性液體。河北阻燃發(fā)泡劑</p><p
