塑料管帽以塑代鋼的優(you)勢更(geng)為突出
塑料鋼管護帽的技術改(gai)革通過改(gai)性(xing)的塑料部件(jian)不僅能(neng)夠達到一(yi)些鋼材(cai)的強度性(xing)能(neng)，還(huan)具(ju)有(you)質(zhi)輕、色彩豐富、易成型等一(yi)系(xi)列優點(dian)，因此(ci)目前“以塑代鋼”的趨勢在很多行業(ye)都顯現出來，而現階段要找(zhao)出一(yi)種大規模替代塑料制品的材(cai)料幾乎是不可(ke)能(neng)的。

　　塑(su)(su)料(liao)鋼管護帽此外，原色(se)或(huo)間色(se)亦可(ke)混入白(bai)(bai)色(se)和黑(hei)色(se)調(diao)出深(shen)淺不(bu)一(yi)樣(yang)的(de)色(se)彩(cai)(cai)。在原色(se)或(huo)間色(se)參(can)加白(bai)(bai)色(se)便(bian)可(ke)配(pei)出淺紅，粉紅，淺藍，湖藍等色(se)彩(cai)(cai);若(ruo)參(can)加不(bu)一(yi)樣(yang)份量的(de)黑(hei)色(se)，便(bian)可(ke)配(pei)出棕(zong)(zong)，深(shen)棕(zong)(zong)，黑(hei)綠等不(bu)一(yi)樣(yang)色(se)彩(cai)(cai)。不(bu)一(yi)樣(yang)五顏六(liu)色(se)農(nong)地(di)膜具有除草或(huo)避蟲、育秧塑(su)(su)料(liao)管帽等作用。即通過配(pei)色(se)上色(se)還(huan)可(ke)抵(di)達(da)塑(su)(su)料(liao)法蘭(lan)蓋某種(zhong)使用上的(de)需要。
鋼管護(hu)帽制作工藝熱(re)固(gu)性塑(su)(su)料(liao)(liao)(liao)(liao)通(tong)(tong)(tong)常含(han)(han)有(you)(you)填料(liao)(liao)(liao)(liao)且一(yi)般為(wei)不(bu)(bu)透明，如(ru)不(bu)(bu)含(han)(han)填料(liao)(liao)(liao)(liao)時為(wei)通(tong)(tong)(tong)明。彈性體(ti)具橡膠狀(zhuang)手感，有(you)(you)一(yi)定的拉伸(shen)率。塑(su)(su)料(liao)(liao)(liao)(liao)管帽的商品按(an)照功能和價格(ge)遞(di)加的次序，我(wo)們能夠分(fen)為(wei)通(tong)(tong)(tong)用塑(su)(su)料(liao)(liao)(liao)(liao)、通(tong)(tong)(tong)用工程塑(su)(su)料(liao)(liao)(liao)(liao)和特種工程塑(su)(su)料(liao)(liao)(liao)(liao)三大(da)類。位于(yu)階梯底部的通(tong)(tong)(tong)用塑(su)(su)料(liao)(liao)(liao)(liao)功能單一(yi)，價格(ge)低，平時應用zui多，因此(ci)zui為(wei)多見。熱(re)塑(su)(su)性塑(su)(su)料(liao)(liao)(liao)(liao)在(zai)溶(rong)(rong)劑(ji)中(zhong)會(hui)發(fa)作溶(rong)(rong)脹，但通(tong)(tong)(tong)常不(bu)(bu)溶(rong)(rong)于(yu)冷溶(rong)(rong)劑(ji)。在(zai)熱(re)溶(rong)(rong)劑(ji)中(zhong)，有(you)(you)些熱(re)塑(su)(su)性塑(su)(su)料(liao)(liao)(liao)(liao)會(hui)發(fa)作溶(rong)(rong)解，如(ru)聚乙烯溶(rong)(rong)于(yu)二甲苯中(zhong)，熱(re)固(gu)性塑(su)(su)料(liao)(liao)(liao)(liao)在(zai)溶(rong)(rong)劑(ji)中(zhong)不(bu)(bu)溶(rong)(rong)，通(tong)(tong)(tong)常也不(bu)(bu)發(fa)作溶(rong)(rong)脹或僅細(xi)微(wei)溶(rong)(rong)脹，彈性體(ti)不(bu)(bu)溶(rong)(rong)于(yu)溶(rong)(rong)劑(ji)，但通(tong)(tong)(tong)常會(hui)發(fa)作溶(rong)(rong)脹。
