pe塑料袋在我们的生活中经常使用。它们分为许多不同的类型，适用于不同的领域。在我们的日常生活中，我们经常使用PE塑料袋。pe是聚乙烯的简称，聚乙烯是由乙烯聚合而成的热塑性树脂。它具有许多优点，可用于服装、箱包、电子产品等包装。这主要是由体育的突出特点决定的。PE塑料袋的特点是什么?下面是PE塑料袋厂家的介绍。

Pe plastic bags are often used in our life. They are divided into many different types and are applicable to different fields. In our daily life, we often use PE plastic bags. Pe is the abbreviation of polyethylene, which is a thermoplastic resin polymerized from ethylene. It has many advantages, can be used for clothing, bags, electronic products and other packaging. This is mainly determined by the outstanding characteristics of sports. What are the characteristics of PE plastic bags? The following is the introduction of PE plastic bag manufacturers.

 

优良的耐腐蚀性和电气绝缘(特别是高频绝缘)。可采用氯化、化学交联、辐射交联等方法改性。低压聚乙烯具有熔点高、硬度高、强度大、吸水率低、电性能好、抗辐*性能好等特点;高压聚乙烯具有良好的柔韧性、伸长率、冲击强度和渗透性;UHMWPE具有较高的冲击强度、抗疲*性能和耐磨性。低压聚乙烯适用于制造耐腐蚀零件和绝缘零件;高压聚乙烯适用于制膜;高分子量聚乙烯(UHMWPE)适用于减震、耐磨、传动部件。

 

Excellent corrosion resistance and electrical insulation (especially high-frequency insulation). It can be modified by chlorination, chemical crosslinking, radiation crosslinking, etc. Low pressure polyethylene has the characteristics of high melting point, high hardness, high strength, low water absorption, good electrical properties, and good radiation resistance; High pressure polyethylene has good flexibility, elongation, impact strength and permeability; UHMWPE has high impact strength, fatigue resistance and wear resistance. Low pressure polyethylene is suitable for manufacturing corrosion resistant parts and insulating parts; High pressure polyethylene is suitable for film making; High molecular weight polyethylene (UHMWPE) is suitable for shock absorption, wear resistance and transmission parts.

造型特点:1。结晶物料吸湿性小，不需要充分干燥，流动性好，对压力敏锐。适用于成型时采用高压注射，料温均匀，充型速度快，保压充分。不宜采用直浇口，以防不均匀收缩，增加内应力。注意浇口位置的选择，防止缩孔变形。2. 收缩幅度和收缩值大，方向性明显，易变形和翘曲。冷却速度要慢，模具要设有冷料袋，还有冷却系统。3.加热时间不宜过长，否则会发生分解。4. 当软塑件有较浅的侧槽时，可以用力脱模。5. 熔体可能断裂，不建议与溶剂接触，防止开裂。

 

Modeling features: 1. Crystalline material has low moisture absorption, does not need to be fully dried, has good fluidity and is sensitive to pressure. It is suitable for high-pressure injection during molding, with uniform material temperature, fast filling speed and sufficient pressure holding. The straight gate should not be used to prevent uneven shrinkage and increase internal stress. Pay attention to the selection of gate location to prevent shrinkage deformation. 2. Large shrinkage amplitude and value, obvious directivity, easy to deform and warp. The cooling speed should be slow. The mold should be equipped with a cold material bag and a cooling system. 3. The heating time should not be too long, or decomposition will occur. 4. When the soft plastic parts have shallow side grooves, force demoulding is allowed. 5. The melt may break, so it is not recommended to contact with the solvent to prevent cracking.
