For the food packaging industry, the gas permeability of the biaxially stretched PP film is lower. To reduce permeability, the first is to reduce the permeability of PP material, which can be achieved by filling and modifying, but the effect is not very obvious. The two is to reduce permeability through blocking the contact between PP film and gas. It is also easy to achieve the following 2 methods. BOPP can be used to separate gas by spraying, such as spraying two vinyl chloride?or?vinylidene ethyl alcohol to the surface of the membrane, with a thickness of about 0.0075 millimeters. Another method is vacuum aluminizing, with a thickness of about 0.0002 millimeters to block oxygen and so on. 3.PP needling omentum The membrane is an upgrading product of the tear film, and it can be used in sewing thread, carpet weaving, marine fishing and other industries. The process flow is as follows: Feeding, extrusion, film cooling, cutting and dividing wire, three roll traction, heating, stretching, needle forming fiber, heat treatment, cooling setting and winding. The temperature of the fuselage: 220, 230, 260, 255 C, the head temperature 250 C, the die head 250 centigrade, the PP melt index 1.5-4 g /10. The film cooling, water temperature 38 C, hot stretching temperature 150-165 degrees C, tensile multiple 5-6 times, cooling roll speed is lower than heat treatment roll speed 2-5%, stretching speed of 240 meters / points. 4.PP isolation membrane The PP isolation membrane can be used as an isolating layer between the conductor and the rubber insulation in the wire and cable. It can prevent adhesion between metal conductor and rubber sleeve. The process flow is as follows: Ingredients, kneading, extrusion, blowing and cooling, traction, cutting, winding, cutting and inspection. The melting index of the PP material is below 3.5 g /10. The extruder temperature is 180, 190-200, 200-210 C, and the temperature of the die head EEA In storage, we should keep away from the fire source, heat insulation, keep dry and clean in the warehouse, strictly prohibit any impurities mixed, strictly prohibit the sun and rain. Transportation should be stored in a clean, dry and roofed carriage?or?cabin, and no sharp objects such as iron nails are allowed. It is strictly prohibited to mix organic solvents such as flammable aromatic hydrocarbons and halogenated hydrocarbons. For example, the four liters of mineral water in a farmer's spring is a big bucket, which is the material. Recycling (2) the typical representative of the ring tube reactor process ring tube reactor process is the Phillips process of Phillips company and 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, and then enter the loop reactor, ethylene monomer after refining, and hydrogen, a TIGI olefin monomer 1 pre mixed and 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 and very uniform mixing of the material in the reactor, and the reaction heat is evacuated evenly from the jacket cooling water. The MI range of this process is 0.15 - 100, and 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 and 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 and circulating diluent isobutane after drying, and then sent into a multi loop continuous flow reactor, and catalyst is added into isobutane into a reactor. The reaction temperature is 106.7 degrees centigrade, and the pressure is 3.9MPa. The polymer and 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% and the conversion rate is 98% - 99%. The polymer is discharged after the flash evaporation to discharge the isobutane and the residual monomer into the diluent recovery unit. Other solid polymers are mixed with additives and granulation. 2, gas phase polymerization and gas phase polymerization (gas phase fluidized bed method) typical process for Innovene technology univation Technology chemical company DOW univation technology and INNOS company by low pressure gas phase fluidized bed reactor using z/n catalyst and 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 and maintenance. The production process is: dry monomers with hydrogen added to a reactor system, the raw material into a large circulation steam flow circuit, and 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 and 12.44% nitrogen. This raw gas consists of the production of the product with the 8g/10min melt index and the density of the 0.964g/cm3. The catalyst consists of titanium trichloride and tetrahydrofuran for two Magnesium Oxide mixture accelerator, AlEt3 catalyst. The catalyst enters the device in the form of solid state and nitrogen from the non pain reactor. The operating temperature is 105 centigrade, and the specific temperature is determined according to the brand name. The reactor pressure is 2.0MPa, and the reaction gas comes out from the top of the reaction. The cyclone separates the catalyst containing solid material and sends it back to the reactor. Then the gas from the cyclone separator is circulated to the bottom of the reactor after the compression and 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, and separation tank. The polymer comes out from the lower part of the discharge tank and enters the washing tank and the post treatment system.
