FAQ

What is the specific weight of plastic film?

This proportion has not, now known as the density of common units is g / cm3 (g/cm fand), kg / cubic meter (kg/dm tons / m3 (fand), fand t/m).

What are the composite ways of plastic film?

The solvent free composite method is a plastic film with pre - coated hot melt adhesive. Press the rollers together with another layer of plastic film. This way, less pollution, energy saving and energy-saving composite section, is the direction of future development. However, because of the high cost of solvent free composite equipment, as well as composite glue and technical reasons, there is still very little domestic use.

Several forming methods of plastic film and their advantages and disadvantages are summarized

I can only talk about it in general, because it involves plastic film forming, there are too many things, and there are so many kinds of plastic film.

How many days can the concrete be taken away from the concrete?

Cover water conservation according to the outside temperature in general should be concrete after pouring 3 material 12h with straw, Luxi, sacks, sawdust, wet soil and wet sand of the concrete cover, and regular watering to keep moist. Concrete watering maintenance date, Portland cement, ordinary cement and slag cement mixing concrete may not be less than 7 days and nights. Mixing with retarding admixture or concrete with impermeability shall not be less than 14 days and nights; when using bauxite cement, not less than 3 days and nights. The number of daily watering can keep concrete with sufficient moist condition is appropriate, when the air temperature is above 15 DEG C, in the concrete pouring after 3 days in the daytime, at least every 3 hours a night should also be watering, watering two times, after the maintenance, at least 3 times every day watering (of course, when the temperature of the drying can increase the number of water right). For the larger area (or volume) of concrete, should adopt the "water conservation" for reservoir engineering in the demolition of the internal model, concrete reaches certain strength water conservation; to the underground structure or foundation, can be renewed by brushing the surface of asphalt emulsion or soil backfill instead of water conservation.

How to choose PE plastic packing film

Transmittance and haze are important indexes that determine the visibility and clarity of packaged goods, and have a great influence on the display effects of goods. Transmittance and fog are expressed as percentages. The greater the transmittance, the better the transparency of the film; and the greater the haze, the greater the opacity of the object through the film, the less clarity.
