塑料袋是我們生活中經(jīng)常會使用到的一種用品，它分為很多的不同種類，適用于不同的領(lǐng)域。在我們的日常生活中，我們也經(jīng)常會用到PE塑料袋，PE是聚乙烯的簡稱，是由乙烯聚合而成的熱塑性樹脂。它的好處有很多，可用于包裝服裝、箱包、電子產(chǎn)品等。這主要由PE的杰出特性決定的，那么PE袋有著怎樣的特性呢？下面就由PE袋生產(chǎn)廠家為我們介紹一下。

Plastic bags are often used in our life. They are divided into many different types and are suitable for different fields. In our daily life, we often use PE plastic bags. PE is the abbreviation of polyethylene, a thermoplastic resin polymerized by ethylene. It has many advantages and can be used for packaging clothing, bags, electronic products, etc. This is mainly determined by the outstanding characteristics of PE. What are the characteristics of PE bags? Next, the PE bag manufacturer will introduce it to us.

耐腐蝕性,電絕緣性(尤其高頻絕緣性)優(yōu)良,可以氯化,化學(xué)交聯(lián)、輻照交聯(lián)改性,可用玻璃纖維增強(qiáng).低壓聚乙烯的熔點,剛性,硬度和強(qiáng)度較高,吸水性小,有良好的電性能和耐輻射性;高壓聚乙烯的柔軟性,伸長率,沖擊強(qiáng)度較好;高分子量聚乙烯沖擊強(qiáng)度高,耐疲勞,耐磨.低壓聚乙烯適于制作耐腐蝕零件和絕緣零件;高壓聚乙烯適于制作薄膜等;高分子量聚乙烯適于制作減震,耐磨及傳動零件。

Excellent corrosion resistance and electrical insulation (especially high frequency insulation). It can be modified by chlorination, chemical crosslinking and irradiation crosslinking. It can be reinforced by glass fiber Low pressure polyethylene has high melting point, rigidity, hardness and strength, low water absorption, good electrical properties and radiation resistance; High pressure polyethylene has good flexibility, elongation and impact strength; High molecular weight polyethylene has high impact strength, fatigue resistance and wear resistance Low voltage polyethylene is suitable for making corrosion-resistant parts and insulating parts; High pressure polyethylene is suitable for making films, etc; High molecular weight polyethylene is suitable for shock absorption, wear resistance and transmission parts.

成型特性：

Forming characteristics:

1.結(jié)晶料,吸濕小,不須充分干燥,流動性好，流動性對壓力反應(yīng)靈敏,成型時宜用高壓注射,料溫均勻,填充速度快,保壓充分.不宜用直接澆口,以防收縮不均,內(nèi)應(yīng)力大.注意選擇澆口位置,防止產(chǎn)生縮孔和變形.

1. The crystalline material has small moisture absorption, does not need to be fully dry, has good fluidity and is sensitive to pressure. High pressure injection should be used during molding. The material temperature is uniform, the filling speed is fast and the pressure is fully maintained Direct gate should not be used to prevent uneven shrinkage and large internal stress Pay attention to the gate psition to prevent shrinkage and deformation

2.收縮范圍和收縮值大,方向性明顯,易變形翹曲.冷卻速度宜慢,模具設(shè)冷料穴,并有冷卻系統(tǒng).

2. Large shrinkage range and value, obvious directionality, easy to deform and warp The cooling speed should be slow. The die is equipped with cold material cavity and cooling system

3.加熱時間不宜過長,否則會發(fā)生分離.

3. The heating time should not be too long, otherwise separation will occur

4.軟質(zhì)塑件有較淺的側(cè)凹槽時,可強(qiáng)行脫模.5.可能發(fā)生融體破裂,不宜與溶劑接觸,以防開裂。

4. When soft plastic parts have shallow side grooves, they can be forcibly demoulded. 5 Melt fracture may occur and should not be in contact with solvent to prevent cracking.
