tpe加工工艺tpe弹性体材料可采用注塑，挤出，吹塑，流涎，浇注等进行加工成型。根据tpe的硬度及物性的不同，加工温度有较大的差距。一般加工温度在110-230℃.视加工，tpe材料配方的不同，设备的差异而存在加工温度的不同。因此，建议在采购塑料原料时，向商所购tpe材料的建议加工温度，压力等参数。tpe g2705、tpe g2712、

lldpe树脂的特性一般体现在熔融和密度。熔融可映出树脂的平均量且主要受应温度控制。平均量与量分布(mwd)无关。催化剂选择影响mwd。密度由共聚用单体在聚链中的浓度决定。共聚用单体浓度控制短支链数目(其长度取决于共聚用单体类型)从而控制树脂密度。共聚用单体浓度越高，树脂密度越低。在结构上，lldpe在支链的数目和类型上与ldpe不同，高压ldpe有长支链，而线性ldpe只具有短支链。在结构上，lldpe只在短支链数目上与hdpe不同。hdpe的短支链数目较少，因此，是有更高密度的材料。lldpe的物理特性受控于它的量，mwd和密度。lldpe优于ldpe，归根结底取决其用途。通常，在所有应用中用lldpe生产刚性的产品，虽然根据at对低密度材料，lldpe和ldpe的密度都在0.91-0.925之间。lldpe形成更高结晶结构，因为不存在长支链。lldpe较大的结晶性产生较高刚性的产品。这种较高的结晶度也使lldpe与ldpe相比，熔点了10~15℃。

(2) the typical representative of the ring tube reactor process ring tube reactor process is the phillips process of phillips company&the innovene s process of ineos company. phillips process using isobutane as diluent, the chromium catalyst, the catalyst must be activated before use, isobutane activated catalyst powder with high purity under the protection of nitrogen formed catalyst slurry,&then enter the loop reactor, ethylene monomer after refining,&hydrogen, a tigi olefin monomer 1 pre mixed&then injected into the loop reactor, the ethylene production of polyethylene in the presence of catalyst. the axial flow pump maintains the high speed flow&very uniform mixing of the material in the reactor,&the reaction heat is evacuated evenly from the jacket cooling water. the mi range of this process is 0.15 - 100,&the density is 0.936 - 0.972 g/cm3. the characteristics of the reactor loop is: less equipment, short process, low investment cost; do not produce wax&oligomer, not sticking to the wall; the powder of good shape, easy to transport; depending on the reaction heat jacket of the reactor cooling water out, heat removing easy, convenient adjustment; raw material demand is higher, need purification; copolymerization the monomer using hexene; using isobutane as solvent, the easy escape of residual solvents. the process flow is as follows: fresh polymerized ethylene is mixed with molecular weight regulator hydrogen, antifreeze&circulating diluent isobutane after drying,&then sent into a multi loop continuous flow reactor,&catalyst is added into isobutane into a reactor. the reaction temperature is 106.7 degrees centigrade,&the pressure is 3.9mpa. the polymer&the diluent residual pulp through the axial flow pump at the speed of 6m/s through the loop reactor. reactor water cooling control reaction temperature set in the solid polymer by loop reactor outlet vertical settlement. as a result, the concentration of slurry can reach 55%&the conversion rate is 98% - 99%. the polymer is discharged after the flash evaporation to discharge the isobutane&the residual monomer into the diluent recovery unit. other solid polymers are mixed with additives&granulation. 2, gas phase polymerization&gas phase polymerization (gas phase fluidized bed method) typical process for innovene technology univation technology chemical company dow univation technology&innos company by low pressure gas phase fluidized bed reactor using z/n catalyst&catalyst, purification of raw material into the reactor, resulting in polymerization catalyst storage under the action of reaction in 85~110. [. pressure was conducted for 2.41 mpa, the single pass conversion of ethylene is about 1% ~ 2%, the reaction heat removal mainly through the cooling cycle logistics, mi range of products for the production of 0.01 to 150, the density ranges from 0.915 to 0.970 g/cm3. the characteristics of gas phase fluidized bed polymerization process is: low operating pressure, low temperature; can produce full density polyethylene; catalyst system including titanium, chromium; metallocene catalyst; high purity of raw material, all raw materials are to be refined; without solvent, low energy consumption, low operation cost&maintenance. the production process is: dry monomers with hydrogen added to a reactor system, the raw material into a large circulation steam flow circuit,&through the gas distribution by entering the large fluidized bed reactor at the bottom, according to the design of the reactor material 69.57% (ethylene vinyl content of 99.9%, 0.1%, 10.43%, 7.56% hydrogen oxide) ethane&12.44% nitrogen. this raw gas consists of the production of the product with the 8g/10min melt index&the density of the 0.964g/cm3. the catalyst consists of titanium trichloride&tetrahydrofuran for two magnesium oxide mixture accelerator, alet3 catalyst. the catalyst enters the device in the form of solid state&nitrogen from the non pain reactor. the operating temperature is 105 centigrade,&the specific temperature is determined according to the brand name. the reactor pressure is 2.0mpa,&the reaction gas comes out from the top of the reaction. the cyclone separates the catalyst containing solid material&sends it back to the reactor. then the gas from the cyclone separator is circulated to the bottom of the reactor after the compression&circulating coolers. the reactor discharge through an air lock system intermittently to product tank. part of the gas entering the discharge tank enters the compressor cycle system through the upper buffer tank, filter, gas cooler,&separation tank. the polymer comes out from the lower part of the discharge tank&enters the washing tank&the post treatment system.
