生产过程：

1， 材料准(zhun)备：称(cheng)量80公(gong)(gong)(gong)斤(jin)线(xian)性(xing)低(di)密度(du)聚乙(yi)烯7042，20公(gong)(gong)(gong)斤(jin)高压聚乙(yi)烯2426H,抗氧剂(ji)1010和168各0.05公(gong)(gong)(gong)斤(jin)，紫(zi)外光吸收剂(ji)uv5310.06公(gong)(gong)(gong)斤(jin)，黑色母(mu)粒(li)5公(gong)(gong)(gong)斤(jin)到10公(gong)(gong)(gong)斤(jin)（地膜厚度(du)小(xiao)于(yu)0.001的添(tian)加10公(gong)(gong)(gong)斤(jin)，厚度(du)大于(yu)0.002毫米的添(tian)加5公(gong)(gong)(gong)斤(jin)），加入(ru)搅拌机搅拌5分钟备用。

2， 挤出机预热：一组温(wen)(wen)度(du)(du)(du)150度(du)(du)(du)，二组温(wen)(wen)度(du)(du)(du)160度(du)(du)(du)，三组温(wen)(wen)度(du)(du)(du)170度(du)(du)(du)，三通(tong)弯头(tou)温(wen)(wen)度(du)(du)(du)160度(du)(du)(du)，模头(tou)温(wen)(wen)度(du)(du)(du)150度(du)(du)(du)，温(wen)(wen)度(du)(du)(du)到达指定数据后，恒温(wen)(wen)20分(fen)钟。

3， 投料生产：把准备(bei)好(hao)的材料加入料斗(dou)后(hou)，缓(huan)缓(huan)启动(dong)主机(ji)，开(kai)(kai)启牵(qian)引机(ji)，收(shou)卷(juan)机(ji)，鼓风机(ji)，慢慢加气，用刀剖分(fen)薄(bo)膜，最后(hou)测量厚度，宽度，到达预定数据后(hou)，开(kai)(kai)始(shi)收(shou)卷(juan)，称重，打包(bao)。
