The composition and principle of the film blowing machine

Laboratory film blowing machine is to heat and melt the plastic particles and then blown into thin film blowing machine is divided into many kinds, such as PE, POF, etc..
With the new particles are blown out of the new material, the color is said to be clean, good bag. Some people made of recycled plastic bags to the particle, the particle is generally called the old material, made of particles is usually gray, usually made in the bag to add pigment, the bag made of uneven color, brittle and easily broken, the price is low.
Blown film machine is suitable for all kinds of high-grade film packaging. The film is widely used in light and heavy packaging because of its good barrier property, preservation, anti humidity, anti frost, oxygen and oil resistance. Such as a variety of fresh fruit, meat, pickles, fresh milk, liquid drinks, medical supplies, etc..
Film blowing machine is composed of the motor motor, screw and barrel, mold head die head, inverter inverter, V board, on the wheel, smooth wheel, wheel, roll wind these nine parts.
Raw materials LLDPE and LDPE temperature is 160--180 degrees HDPE temperature is 210-230 degrees film blowing machine work is the most important one of the three factors temperature (machine temperature, room temperature) two spiral cooling system three
Classification of PE blown film machine
PE classification is high and low pressure blowing machine blowing machine can be divided into single head and double head film blowing machine, film blowing machine, according to the configuration is divided into double roll film blowing machine, film blowing machine and rotating head PP PP film blowing machine, film blowing machine is divided into two layers of PP film blowing machine, film blowing machine, three layer PP and composite film blowing machine is divided into two layers: three layer co extrusion film blowing machine, film blowing machine, film blowing machine, the PA PVC POF film blowing machine, film blowing machine, film blowing machine, bag PP tear film blowing machine etc.
PE materials refer to?
PE material is polyethylene, is the largest amount of plastic materials, it is made of polyethylene polymer materials. Basically divided into two categories: low density polyethylene LDPE; high density polyethylene HDPE. PE materials in accordance with international standards are divided into five levels: PE32, PE40, PE63, PE80 and PE100. PE uses a wide range, and is divided into high density, low density and linear PE, the most commonly used to make a variety of plastic film and plastic sheeting. A medium density polyethylene pipe and PE pipe with high density polyethylene pipe. According to the wall thickness is divided into SDR11 and SDR17.6 series. The former is suitable for transporting gas, artificial gas, natural gas and liquefied petroleum gas.
Compared with the steel pipe, the construction technology is simple, and has a certain flexibility, the more important is not to be used for anti-corrosion treatment, will save a lot of processes. Disadvantages of the equipment is not as good as the steel pipe, the construction of the special attention to the safety of heating heating space, and can not be exposed to the air in the sun, and sensitive to chemicals, to prevent leakage of the sewage pipe damage.
