FAQ

PVC plastic film, ultrasonic welding machine welding, welding can.

PVC film fused traditional method is the use of high frequency welding machine, if you must do something to subvert the traditional innovation, it is rather difficult to estimate, ultrasonic machine in the welding of PVC films when there is no way out with the same high frequency welding welding effect.

Is it good to use paper bags or plastic film bags?

With asbestos mesh (general dish pack more use of this media) direct contact with the disk, the relative effect is better

Is plastic film the same as glass cloth?

Not the same, plastic film is not leaking, glass cloth is woven out of leakage

Is it beneficial or harmful to wrap trees in plastic film?

Wrapped grass first with straw or directly to the trunk wrapped with straw tied membrane, and then fixed on the trunk with fine grass. Then with the water or spray will spray wet straw, can also be careless or straw soaked and package. The plastic bag in the careless orstraw strapping on the trunk will last film. The lower part of the trunk is close to the soil ball to spread the film. After the foundation is covered with soil, it is covered with plastic film. Plastic film surrounding soil pressure, so that the use of soil temperature regulation, to ensure that the parcel trunk space is sufficient temperature and humidity, and avoid the work of adding water.

What is a water-soluble plastic packing film?

Water soluble plastic packaging film as a new green packaging materials. The main raw material is low alcoholysis of polyvinyl alcohol film, water solubility and degradability by polyvinyl alcohol, adding various additives, such as surfactants, plasticizers, anti adhesive agent. Water soluble film products belong to green packaging materials and in Europe, Japan and other countries have been recognized by the national environmental protection department. At present, the main domestic and foreign biological oxygen demand (BOD) and chemical oxygen demand (COD) as an environmental indicator. The Japanese authorities determination of PVA biological oxygen demand (BOD) is much smaller than the starch, the United States Air Products to PVA biological products Airvol, after 5 days degradation can be measured the amount of BOD is lower than the initial volume of BOD 1%. through the biological experiment proved that polyvinyl alcohol are non-toxic, does not prevent the growth of microorganisms, has no influence on wastewater treatment and environmental health The microbial decomposition tests also showed that the PVA was almost completely decomposed, resulting in a very low COD

Is the foundation covered with film or damp proof powder?

1, I do not know what is the principle of moistureproof powder?. It is estimated that it is additive. But not added to mortar, doubt the function.2, the film will be better, but the follow-up construction is easy to damage, durability is limited, it is better to do a waterproof.3, on the foundation moistureproof, equal to did not do. It is no use crossing a block of water in the middle of the pool. Damp proof should be done below ground level.4, I don't think the film is better than the traditional damp proof layer. Can the height on the ground, construction (brick), can play a role of natural moisture barrier; or on the ground part of the wall construction waterproof isolation layer.

UV ink coated on plastic film, LED light cured, wrinkled, and what is the reason?

Temperature dependent, cured with UV cold light

Can electrostatic generator adsorb plastic film?

The output of the electrostatic generator in the electrostatic discharge generator is positive and negative, and some positive and negative can be converted. Their voltage is bipolar, high-precision, and the output is continuously adjustable. The utility model is suitable for more application fields and the requirements of the new standards in the future, so the electrostatic discharge generator can be used for the electrostatic discharge test of most electrical and electronic equipment.
