Drinking Straw Machine Good barrier property

The film made of film blowing machine is good for its barrier properties, fresh, moisture resistant, frost proof, oxygen resistant, oil resistant, widely used in weight packaging. It is widely used in such fields as fresh fruit, meat, pickles, fresh milk, liquid beverage and medical supplies. In order to facilitate the film blowing film and the normal blowing film, the temperature of the film blowing machine requires the optimal temperature, how the temperature will be controlled.

According to the melting theory of plastic, the extruder screw of blowing film is divided into three parts: the feeding section, the melting section and the homogenization section. At the end of the feeding segment, at the beginning of the melting section, according to the melting theory, its temperature should be the viscous temperature. The viscosity-flow temperature of various film and film resin is PP: 164-175 degrees, PE: 105-135 degrees Celsius, PA: 195-210 degrees Celsius. The environment determines the quality of the product.

The material of Boeing software is PVC plastic blown film forming, and the width and thickness are controlled by the blowing machine and the die head. At present most of the use of 0.18 ~ 0.22 thickness to make plate surface coating. The surface texture of the Boeing film is molded by moulding process, and it is also coated with adhesive glue. It is characterized by low cost and easy to use, which is the reason of temperature change due to temperature change in the material forming, and it is different in each batch. Since PVC is a flame retardant material, it also serves as a surface flame retardant to be used in building materials. The disadvantage is that when coating glue the individual oil trace glue degumming, the adhesion is bad, easy foaming, the surface hardness is poor. So Boeing film factory production.

Proper operation of the blowing machine:

1. Check that the temperature control is in good condition and the heating appliance is in good condition, and the heating temperature of each point should be adjusted in a timely manner.

Check the traction speed and control the film thickness.

3. Observe and adjust the thickness of the film to meet the standard.

4. Check air storage cylinder pressure, not too high, but should have backup pressure.

5. Check the proportion of raw materials and mix them evenly.

6. Check the raw materials for impurities, and make sure to use the magnet to check the iron in time.

7. Check the speed of deceleration box and air cylinder lubricating oil.

8. Regularly check the temperature rise and mechanical transmission of each running motor.

The straw is the principle of atmospheric pressure. When used, the suction of some air from the straw will cause the pressure to decrease in the pipe. In order to balance the air pressure, the atmospheric pressure will force the liquid to rise in the pipe. When you stop inhaling, the fluid drops in the tube, and the pressure returns to equilibrium. This is the wonderful principle and application of the straw.
