Package of PVB film:
- Q:Why plastic film greenhouse can keep warm?
- Because the heat is hard to escape through the plastic film, the temperature difference between the upper and the lower of the greenhouse can not be enlarged, and the convection is very small, so that the heat can be kept warm. The key here is the plastic film is very similar to shun donkey, sun radiation from the inside, with stubble, almost without shelter; and the heat from the inside out is the inverse stubble, resulting in heat insulation.
- Q:Do you want to remove the wrapping plastic film from the new mattress?
- Removing plastic film from packing can release moisture and harmful gas from the material left in the manufacturing process, and prevent the filling from mildew or rust.
- Q:Installation of air-conditioning machine inside the plastic film did not take off, the impact on the air-conditioning?
- General machine Binet machine should be low, even if not more than 2 meters high, if not otherwise back to normal compressor oil, long time will cause damage to compressor.
- Q:What about the glue left behind the plastic film on the door?
- To have viscose place with cooking oil or oil can be painted on the rubber, two days after a wipe can be clean. This is a very effective way to promote the use of. Not wide is the security door, as long as there are traces of small advertising stickers, you can use this method. Work.
- Q:What PE plastic film?
- Common sanitary bags are made of this material.
- Q:What are the differences between geotextiles and geomembrane?
- Geomembrane construction site geomembrane with plastic film as impervious base material, and non-woven fabric composite soil impermeable material, and its anti-seepage performance mainly depends on plastic film seepage control performance. At present, the domestic and foreign application of impervious plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), which is a kind of polymer chemistry of flexible material, the proportion of small, strong extensibility, high deformability, corrosion resistance, low temperature resistance, frost resistance.
- Q:What are the factors affecting the puncture strength of plastic film?
- The general physical and plastic film thickness, tension, the heat and other factors, but also has a relationship with the processing of materials used in production, if not assured the puncture strength of plastic film is not qualified, can choose the market force commonly used CCY-02 puncture tester to check.
- Q:How can concrete pavement be cured after being pressed? In general, concrete curing is made of thin films and concrete pavements
- The best way is: the final condensate to the wet cover after maintenance.Can buy a cheap regeneration blanket, inside is recycled knitting silk, the outside is recycled cotton, commonly known as "black heart cotton" material. A lot of furniture transportation is also used to put the bump.
- Q:What are the factors affecting the permeability of plastic film?
- Water column height. In the water permeability test, the water quantity in the water cup is changed, indicating that the water column height has no influence on the test result, so the water quantity is not strictly controlled, and the amount of the water can be poured into the water permeable cup with proper amount of water.
- Q:Can the barrier in the refrigerator be covered with plastic film?
- The shelf in the refrigerator can be affixed with plastic film according to the use, and no influence on the use of the refrigerator.
PROTECT, is the professional manufacture Enterprise with the largest investment scope, the most comprehensive product Specifications, strong production capacity and the highest sales volume, mainly produce special materials PVB and EVA film for bullet-proof glass, windscreen of the automotive, architectural safety glass as well as solar cell panel.
