乙烯 --- 石油提炼中产生的一种气体 Monoethylene --- a gas produced in petroleum refining

线型高密度聚乙烯本色是一种不透明白色腊状材料,比重比水轻,柔软而且有韧性,但比 LDPE 略硬,也略能伸长,无毒,无味 PE 片材挤出机 ,PE 设备(图示) Natural linear high-density polyethylene is an opaque white wax-like material. Its specific gravity is lighter than water, soft and tough, but slightly harder than LDPE , and slightly stretchable, non-toxic, tasteless PE sheet extruder . Equipment (illustrated)

易燃,离火后能继续燃烧,火焰上端呈黄色,下端呈蓝色,燃烧时会熔溶,有液体滴落,无黑烟冒出,同时,发出石腊燃烧时发出的气味 The combustion characteristics are flammable, and it can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It will melt when burning, liquid drips, and no black smoke comes out.

LDPE HDPE 的差别主要是在密度上的差别,从而引起机械性能上的差别,一个刚硬,一个柔韧; LLDPE 与它们的差别,主要是在分子结构上, LLDPE 有较多的支链,因此,这种材料是即柔韧又刚硬。 The difference between LDPE HDPE and LLDPE three materials: The difference between LDPE and HDPE is mainly the difference in density, which causes the difference in mechanical properties, one is rigid and the other is flexible; The difference between LLDPE and them is mainly in molecular structure. LLDPE has more branches, so this material is both flexible and rigid.

耐酸碱,耐有机溶剂,电绝缘性优良,低温时,仍能保持一定的韧性。 Advantages Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and still maintain a certain toughness at low temperatures. LDPE ,但低于 HDPE LLDPE 的抗穿刺性是的,耐撕裂,特别适宜生产薄膜,生产出的薄膜比 LDPE 薄,但强度高。 Surface hardness, tensile strength, rigidity and other mechanical strengths are higher than LDPE , but lower than HDPE ; LLDPE has puncture resistance, tear resistance, and is particularly suitable for producing films. The produced films are thinner than LDPE , but have higher strength.

机械性能差,透气差,易变形,易老化,易发脆,脆性低于 PP ,易应力开裂,表面硬度低,易刮伤。 Disadvantages Poor mechanical properties, poor breathability, easy deformation, easy aging, brittleness, brittleness lower than PP , easy stress cracking, low surface hardness, easy to scratch. Difficult to print. When printing, surface discharge treatment is required. It cannot be electroplated and the surface is matte.

用于挤出包装薄膜,胶带,电缆;生产出的薄膜,也叫拟纸薄膜 Uses for extruding packaging films, tapes, cables; produced films, also known as paper-like films

For injection molding of low-grade daily necessities and shells

For extrusion blow-molded containers, hollow products, bottles

一般的 LLDPE 熔点为 170 ℃,分解温度为 300 ℃;注塑温度的可调区间较大。 The general injection molding performance of LLDPE has a melting point of 170 ° C and a decomposition temperature of 300 ° C; the adjustable range of the injection temperature is relatively large. 200 --260 ℃;它的表观粘度大,流动性差,单独的 LLDPE 难以注塑,因此,要加大注塑机的功率或加其它低分子量的塑料增加它的流动性;因是烯烃类塑料,它不吸水,生产时,不需哄干,但为了产品质量,可用 60 ℃温度烘干 1hr ,以排出浮水;线型低密度聚乙烯的熔体粘度大,流长比小,流动性低于 LDPE HDPE ,薄壁制品可能缺胶,因此,浇口和流道相对较大;制品易带静电,表面易吸尘埃。 When injection molding, the general use temperature is 200 --260 ℃; it has a large apparent viscosity and poor fluidity, and LLDPE alone is difficult to injection. Therefore, increase the power of the injection molding machine or add other low molecular weight plastics to increase its flow. Because it is an olefinic plastic, it does not absorb water and does not need to be dried during production, but for product quality, it can be dried at 60 for 1hr to discharge floating water; linear low-density polyethylene has a high melt viscosity and a smooth flow. The length ratio is small, the fluidity is lower than LDPE and HDPE , and thin-walled products may lack glue, so the gate and runner are relatively large; the products are easy to carry static electricity and the surface is easy to vacuum. 16 ‰;溢边值为 0.05mm Shrinkage is 16 ‰; underflow value is 0.05mm

一般的 HDPE 熔点为 142 ℃,分解温度为 300 ℃;注塑温度的可调区间较大。 Generally speaking, the melting point of HDPE is 142 ℃, and the decomposition temperature is 300 ℃. The adjustable range of injection temperature is large. 180 --230 ℃;因是烯烃类塑料,它不吸水,生产时,不需哄干,但为了产品质量,可用 60 ℃温度烘干 1hr ,以排出浮水;聚乙烯的熔体粘度大,流长比小,薄壁制品可能缺胶,因此,浇口和流道相对较大;制品易带静电,表面易吸尘埃。 When injection molding, the general use temperature is 180 --230 ℃; Because it is olefinic plastic, it does not absorb water and does not need to be dried during production, but for product quality, it can be dried at 60 for 1hr to drain water; Ethylene has a high melt viscosity, a small flow length ratio, and thin-walled products may lack glue. Therefore, the gate and the runner are relatively large; the product is easy to carry static electricity and the surface is easy to dust. 16 ‰;溢边值为 0.05mm Shrinkage is 16 ‰; underflow value is 0.05mm
