Heroes, please ask whether the highlight and matting on the surface of the plastic nameplate are sti

1. The difference is: the high-gloss surface is very smooth, and the matte is like a matte effect.

2. The processing ease of both is about the same, but the mirror roller is very expensive, and the frosted roller is cheaper.

High-gloss, high gloss, just like a mirror will be reflective, matte belongs to diffuse reflection, non-reflective, the surface is not reflective as if it has been polished, and a matting agent will be added when the color is generally matched.

There is no such thing, even if someone produces it, it will produce more than 1 2 kinds of keys, not necessarily the kind you want.

This kind of mold can be produced by yourself 4000 5000

It doesn't seem to be producing these anymore, it's hard to find.

If there are many of them, you can open the mold for production.

Polyvinyl chloride.

Most of the profiles used in the exterior of the building are made of PVC.

HDPEPVC, a little more than 3 kinds of these have a characteristic: strong impact resistance.

First of all, I want to say that the previous answer is very unlevel, completely layman PU is polyurethane, but polyurethane is also divided into polyurethane resin (plastic) and polyurethane rubber plastic is divided into thermoplastic and thermosetting plastic, the difference between plastic and rubber is that the plastic can appear a tensile platform during the stretching process (according to the stress-strain curve). Rubber, on the other hand, does not appear as a plateau area when stretched.

Rubber has a broad sense and a narrow sense, cross-linked rubber refers to the narrow sense of rubber, as long as there are two kinds of natural rubber and synthetic rubber. Nowadays, thermoplastic elastomers are also referred to as rubber or thermoplastic rubber.

Polyurethane can be made of rubber or plastic by controlling the composition in the synthesis process.

Plastic is made of PVC plus plasticizer and other additives calendered and compounded on the cloth, the advantage is that it is cheap, colorful, and has a variety of patterns, and the disadvantage is that it is easy to harden and become brittle. PU synthetic leather is used to replace PVC artificial leather, and its ** is higher than PVC artificial leather. In terms of chemical structure, it is closer to leather fabrics, it does not use plasticizers to achieve soft properties, so it will not harden and become brittle, and at the same time has the advantages of rich colors and patterns, and it is cheaper than leather fabrics, so it is popular with consumers.

Rubber is divided into natural rubber and synthetic rubber according to raw materials. According to the form, it is divided into bulk raw rubber, latex, liquid rubber and powder rubber.

Material: RG5

The copper castings of this material have the characteristics of corrosion resistance and high wear resistance, and the mechanical properties are stable at a high temperature of 400 degrees. It is widely used in the shipbuilding, civil, chemical industry, etc., which is equivalent to C83600, and the composition is on the fourth page of the following document.

Seeing that everyone has never used it, let alone the performance of the ingredients, it is estimated that you will have to choose another way. Good luck with an answer soon.

The values of resin parameters starting with k are as follows:

K-value 230 open-cell styrofoam.

Most of the cells are interconnected foam.

231 Cracking.

Cracks on the surface or inside of a product caused by internal stress, external impact or environmental conditions.

232 Mold opening force.

The force required by the molding machine to open the mold in order to remove the product.

233 Engaging in electrostatic agents.

Substances that prevent or eliminate static electricity on plastic surfaces.

Not recommended: Antistatic agents.

234 Mold resistance.

Plastic's resistance to mold.

235 Anti-blocking agent Anti-blocking agent.

A substance that prevents adhesion between plastic films.

236 Furfural resin.

It is a furan resin prepared mainly with furfural and other compounds.

237 Antioxidants.

A substance that prevents deterioration of polymer materials due to oxidation.

Not recommended: Oxidation preventers.

238 Replaceable cavity mold.

By replacing a part of the molded parts, it is possible to produce molds of different shapes.

239 voids (in Styrofoam).

There are many more cavities that form in the foam than the inherent bubbles.

240 (injection molding machine) empty cycle time.

The minimum amount of operating time required for the injection molding machine to run idle for one cycle without feeding.

241 die (in extrusion).

An extruder that forms the extrudate into a defined cross-sectional shape.

242 Pressure in the die.

The pressure generated by the molten material on the inner surface of the die during extrusion.

You can buy this "Coating Process" to check and know, K value is a very important indicator for alkyd resin design and formulation, I forgot the specifics.

Matting paint: 1Prevent the water sticker from falling off, scratching the sticker from being damaged, and the complementary color from oxidizing or falling off.

2.To achieve a certain effect, such as the oil shine will make the model more reflective and look shiny, and the matte will make the model look textured and get rid of the plastic feeling.

3.To a certain extent, it prevents the white from turning yellow.

The effect of semi-matting is weaker than that of matting, and the effect is very similar to matting if you spray a few more layers! And the interest rate on whitish is much, much smaller!

For special Gundams, such as ** Baishi and Dawn, this kind of surface high-gloss treatment is very complicated, and it is very difficult, because the high-gloss varnish is sensitive to the purity of the air and humidity, so novices generally cannot properly make the high-gloss surface.

You can only pay one picture, and it's a matte 5-layer guntank

Eliminate reflections after matting use.

After semi-matting, it is not much different from itself.

Glossiness increases reflection after use.

It depends on what material, how thick it is, and so on! It also depends on what you use it for and what the requirements are!

It's simple, don't use gas first, fill the water, first put the water pressure until it bursts, and you will know how much pressure it can withstand.

The amount of pressure that any one container can withstand is not calculated, it is experimented.
