Plastic foam molding process is divided into three: the formation of bubble nucleation, nuclear expansion and foam curing. To add a chemical blowing agent PVC foam board, the bubbles the expansion of the foam sheet quality of decisive effect. PVC is a straight chain molecule, molecular chain is short, low melt strength, bubbles in the nuclear expansion into bubble process, melt is not sufficient to cover the bubble, gas is easy to overflow into bullae, reduced foam sheet product quality.

Improvement of PVC foam board quality is the key factor to improve the melt strength of PVC. From the polymer processing characteristics of PVC, improve the melt strength method has many kinds, but the most effective way is added to improve melt strength additives and reducing the processing temperature. PVC belongs to the amorphous material, with the melt temperature improve the melt strength decreased, whereas with the melt temperature lower melt strength increase, but the role of cooling limited only play a supporting role. Class ACR processing agent has improved melt strength effect, which is the most effective foam control agent. The melt strength with foam modifier content increases. Generally speaking, as long as the screw rod has enough dispersive mixing ability, add the high viscosity of the foaming regulators to improve melt strength effect is more obvious.

In the PVC foam board, joined ultrahigh molecular weight polymer purposes: one is to promote the fusion of PVC; two is to improve the PVC foaming material melt strength, prevent bubbles combine, to obtain a homogeneous foam products; three is to ensure the melt and has good mobility, in order to get good appearance products. Due to the different foam products manufacturers of products, the use of equipment, technology, raw materials and the lubricating system are different, therefore we have developed with the different properties of the foaming agent, to meet the different needs of users.

The 1 foamed material definition

The foaming plastic is also called foam, is taking plastic as basic composition, containing a large number of bubbles, can saying is to gas filled composites.

The 2 foamed material classification

According to the foaming ratio of different, can be divided into high and low foaming of foaming, foam quality according to the degree of soft, can be divided into rigid, semi-rigid, flexible foam. According to the pore structure can be divided into closed-cell foam and open-cell foam. The common PVC foam sheet of rigid obturator low foamed sheet.

The application of 3.PVC foam sheet

PVC foam sheet has chemical corrosion resistance, weather resistance, flame resistance and other advantages, widely applied in many aspects, including the display panel, mark, billboards, partition, building board, furniture board.

4 key factors in quality evaluation of foaming sheet

The foam, bubble size and uniformity is the key factor influencing sheet quality. In times of low foamed sheet, bubble hole is small and uniform foaming sheet material, good toughness, high strength, good surface quality. From the lower foam sheet density into consideration, only the bubble of small and uniform to further reduce the possibility of foam density, large and scattered difficult to further reduce the density.

A selective membrane, membrane cutting model, in the original car glass of glass bottom length, from the middle of the glass width ( length 5-10cm ), pay attention to the direction of the PVC foil, the glass length corresponds to the long side of the glass membrane, corresponding to the width of the broadside direction cutting membrane membrane, membrane long edges shrinkage, and broadside without.

In two, the cleaning of the glass pot with two or three drops of finger size flexible without harmful substances ( mainly cleaning agents cleaning and lubricating effect ) water strain. In the PVC foil the outside of the glass spray on the amount of water, steel or plastic scraper scraper carefully the whole glass cleaning again, removing the dirt on the glass, spray water, front and rear retaining special water scraping plate once again cleaning glass. If the dirty glass baking on the PVC foil, when the PVC foil heating feeble, scraper PVC foil glass that will leave an imprint in the PVC foil. These imprinted even PVC foil pastes can eliminate, thus affecting the PVC foil quality, appearance and clarity.

Three, grilled prior to membrane plastic bite the PVC foil edges, to distinguish between the protective PVC foil. Protective PVC foil of a face, and a balanced development in the glass, cut out excess ( with glass black side as standard). From the middle of the PVC foil to the upper and lower sides split evenly, two broadside bubbles also together to the upper and the lower sides evenly divide. With a water scraping plate in the middle part of water dry scraping, pay attention not to blow bubbles, to prevent the PVC foil torn, the middle part of the first wiper, role is shaping, the PVC foil does not move, and the membrane of the average bubble as both sides separately, in favor of roasted membrane.

The four PVC foil the bubble size, baked into almost equal parts. From easy to difficult, from small bubbles first baked, roasted small bubbles, in the large air bubbles into small to bake, roast membrane when attention to bake temperature gun and membrane heating degree, distance or speed can be used to regulate the temperature of. Baking bubbles should make bubbles uniformly heated, a PVC foil edge can be properly put roasted gun that 1-2 minutes, so that the PVC foil edge contraction, can shave. Roast membrane side note PVC foil shrinkage degree, when the membrane wrinkles shape contraction, scraper scraping end, if the bubble is too big there is no sure, can handle membrane in smooth, flat scraper. Roasted membrane when not in a bubble residence time is too long, so as to avoid high temperature. When the temperature is too high, the PVC foil light burned, heavy cutting glass. This is not to the car glass water, to prevent the glass can not bear to stimulate self.

Five, trimming baked a membrane to put more than the linesman, front windshield with a rearview mirror, to cut off the black side of 2mm opacity can be. Glass cutting edge: straight, flat, homogeneous.

The pvc foil role:

Reducing the heat loss

In winter, which can effectively reduce the heat loss of the car, the quality of explosion-proof membrane insulation reduces heat loss by up to 34% or so.

Glare filter

Can effectively filter the sun glare at night and two car meeting glare, enhance the comfort and safety.

UV blocking

Ultraviolet light is in the solar spectrum cause skin burns, skin cancer and the car dashboard, seats and textiles fading degeneration of the main factors. To protect the personal safety accident after the broken glass, explosion-proof membrane insulation can be broken glass adhesion in place, to prevent glass from wounding, enhancement of the accident, storms and other disasters prevention ability.

Heat insulation

Professional insulation explosion-proof membrane can block the sun heat during the summer of 50-85%, can significantly reduce the temperature inside the vehicle, improve vehicle comfort. In winter can make the temperature in the car than the car outside the high degree 2-7. So winter paste is very necessary, this should be the season and it doesn’t matter.

Enhanced security

Insulation explosion-proof membrane structure and strong adhesion force, can greatly enhance the strength of glass, enhance the shock resistance performance of the glass, then time delay, experiments show that, when affixed to high quality car explosion-proof membrane, break a piece of glass from the time of a few seconds to tens of seconds to extend. According to police statistics, 10 seconds time is enough to make the criminal mind panic, quit.

Privacy

Many owners of private higher demand. Special automobile heat insulation film has a very good perspective of one-way function, the diaphragm through many physical reflection on the outer surface of the membrane to form a certain proportion of the outer reflective of, from outside the car will produce visual reflex, which is not easy to see inside the person and goods, form some privacy. Perfect the appearance of the character follow the same pattern of the original car transparent glass can not meet many of the perfect appearance and personalized demand. Different shades, different color and appearance of the explosion-proof membrane insulation to the overall look of the car more perfect, more harmonious.

Other film

In addition, also said the mobile phone film, screen protection film, also belong to the film category.

In the textile industry, the release film, bronzing film on top of the flower type, color, and transferred to the surface of the process, called the film. Such as: bronzing film, dry PU.

To make a long story short, the film mainly for protection.
