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?

The external machine is higher than the internal machine, if it is a new machine, the contradiction shows little, once the time is long, there will be a problem.The biggest problem is the oil return system, compressor in high evaporator in the lower, especially in the refrigeration temperature, oil viscosity, oil is not easy to return to the compressor, the compressor oil shortage, especially in the course of time, easy to damage.

Q:What is the raw material of agricultural film?

Agricultural plastic film has a wide range of varieties and specifications. According to the use of plastic, plastic raw materials are different, divided into PVC plastic film, polyethylene plastic film;. According to a method of manufacturing a plastic film, divided into pressure Ting film, blown film; according to some special properties of plastic film with the film, there were no drop seedling film, thin film, thin film, colored cover wide film, packaging film etc.. According to the different thickness and width of plastic film, there are various specifications.

Q:Roof SBS waterproof fine stone concrete protection layer construction, the role of the separation layer?

The separation layer generally uses low grade asphalt roll, composite plastic film.Roofing SBS waterproof fine stone concrete protective layer construction method:1, hot melt method.2, cold sticky method.The method is based on the special hot melt hot melt machine or the bottom surface of the base sheet baking burner, when baking to the bottom surface of the coil shiny black oiled coil has been oiled with melting, the coil can roll forward and roll thickness should base adhesive, hot melt.

Q:Is there any toxicity in the production process of plastic blown film machine?

Plastic film production process is toxic mainly depends on the production of plastic film is what kind of production: polyethylene, polypropylene plastic film is not toxic, but the production of PVC (English plastic film, referred to as PVC) is due to the heating and melting of plastic parts plastic solution to produce hydrogen chloride gas, it will cause harm to human body. In addition according to the requirements of the product in the production process will add color, fluorescent whitening agents, increasing agent such as blue chemical additives, may have a small amount of chemical additives by high temperature decomposition, which will produce harmful substances. In short, the production process, pay attention to standard operation, in order to avoid harmful substances.

Q:Masks that layer of white plastic film is used for what?

The layer of plastic film should take off when doing facial mask, facial mask and do not use, if used together, will lead to the loss of film permeability, but will lose the mask itself, there may also be counterproductive.

Q:What are the factors affecting the puncture strength of plastic film?

The specific operation is as follows: the diameter of test piece 100mm is installed on the fixed clamping ring like membrane, with a diameter of 1.0mm spherical apex radius of 0.5mm needle, thorn to the top with the speed of 50mm/min, the maximum load test piece read needle penetration. I hope I can help you.

Q:What are the main differences between plastic film and paper in printability?

And many plastic film surface tension, humorous printing after the adhesion strength, the extent of adhesion, and now are generally oily ink, general two-way stretch method of production of films can be directly printed,Such as BOPP, BOPA, BPET and so on,

Q:What film plastic is transparent and good for aging?

Performance comparisonAlthough the thermal conductivity of FRP is lower than that of PC, the FRP lighting board is usually a single layer, and the heat conductivity is higher than that of the PC solar panel (multilayer structure), that is to say, the indoor temperature under the FRP lighting board is higher if the sun shines in summer.

Q:How to deal with plastic film greenhouse joints?

Hot tack. Prepare a flat and smooth wood as a plate, screw on the fine iron screens, and fixed on the bench, to prevent damage to the plastic when flipping, with a wooden side edge is made to a smooth plane. Each edge of the two films to be bonded shall be attached to the bar, overlapping each other about 4-5 centimeters. At the same time by the 3-4 operation, the 2 were responsible for the "butt" in the wood on both sides, third people have to sew in the film at a 8-10 cm wide, 1.2-1.5 meters long kraft paper or old newspaper article, cover with electric iron bars along the preheated end, experience with pressure appropriate, slowly to the other end. The electric iron heat, downward pressure, and the speed should be based on two pieces of paper thin film under heated to a certain degree of softening and stick together for the degree, and then the strip, glue a film to the other end of the pull sticks, repeat bonding next section, again, until the film received the required length.
