Q:Fence material outside the plastic inside is iron or steel this material called

Ordinary steel profiles will be deformed, the color is relatively monotonous, usually white, if you want to change the color will add PVC with the film, a long time the PVC film will fade. Automotive supplies industry in the use of steel, the material requirements are relatively high, the most typical is the engine chassis protection board, has been widely used by most riders. Plastic steel is also used in the production of tapered roller bearing cage. Plastic cage has: 1, reduce the friction and roller slip, reduce the working temperature; 2, improve safety and performance; 3, fail safe mode, not stuck.

Q:Bathroom plastic door with what material to do

The plastic material of the bathroom is PVC ? Plastic doors and windows (Plastic doors and windows), that is made of U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features. ? According to the material can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows.

Q:Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah

The so-called 88,80,60, refers to the bottom of the profile width. The unit is millimeter. The profile manufacturers have these specifications are refers to the bottom of the width is the same, but different manufacturers of profile height is not exactly the same.

Q:What is the quality of plastic steel profiles in the end?

Quality in general, market acceptance can be, but the price is relatively high.

Q:What is the amount of plastic profiles

The size of the sliding window lap affects the sealing of the window, safety, installation, daily use and so on. (12mm-8mm = 12mm), the gap between the fan and the ribs of the box (ie, the slide) is 12mm (20mm-8mm = 12mm). ), This gap for windows to install and pick up. When installing the window, the sash and bottom frame are only 4mm at the top of the ribs. Due to the size deviation of the window frame and sash, the straightness deviation of the window frame installation and the height change of the pulley used will change the actual overlap and installation gap of the frame fan. When the amount of overlap between the fan and the upper frame increases, the installation gap decreases, and the window fan is hard to be installed, and the frictional force of the window and the upper seal block increases, resulting in the opening of the sash; Sealing performance decreased, lap volume is too small, but also increase the risk of sliding window off.

Q:PVC plastic profiles dip in the seam, how to deal with seamless docking

Fill too much for the current market price of profiles is low, and the pattern of rising raw material prices, profile manufacturers are to reduce the cost of the article, the formal profile manufacturers through the optimal combination of formula is not to reduce the quality of the premise, Cost; some manufacturers are in reducing costs while also reducing the quality of products. As a result of the ingredients of the formula, the most direct and effective way is to increase the filler, in the PVC-U plastic profile commonly used filler for the calcium carbonate. Most of the previous formula system is to add heavy calcium, the purpose is to increase the rigidity and reduce costs, but the calcium particles because of their irregular shape and relatively thick particle size and PVC resin body compatibility is poor, so the number of its added Low, and the number of copies will increase the color and appearance of the impact. Now with the development of technology, most of the use of ultra-fine light activated calcium carbonate, and even nano-calcium carbonate, which not only play a role in increasing rigidity and filling, but also has the role of modification, but its filling is not Infinitely, the proportion should be controlled. Now some manufacturers in order to reduce the cost of calcium carbonate added to 20-50 copies, which greatly reduces the physical and mechanical properties of profiles, resulting in this chapter referred to the phenomenon of brittle profile.

Q:The difference between steel and aluminum alloy profiles

Plastic windows are easy to weather, aluminum alloy will not. If you want to be insulated when you do windows with double glass

Q:How many meters of a conch plastic steel profile

The length of the material factory standard is 6m Frame material is generally a bundle of four, or a bundle of six, the fan material is generally a bundle of 6-8, pressure line 20 - 30 bundle

Q:Plastic profile brittle extrusion process unreasonable reasons

The low molecular weight of the product is not discharged There are two general approaches to the production of low molecular weight components in the product, one at the time of hot blending, which can be vented through the dehumidification and exhaust system during hot blending, partly by partial residual and extruded heat Water and hydrogen chloride gas. This is usually through the host exhaust section of the forced exhaust system to force the discharge, the vacuum is generally between -0.05Mpa-0.08Mpa, not open or too low, will remain in the product of low molecular weight, Resulting in mechanical properties of plastic profiles decreased, resulting in plastic profiles crisp.

Q:It is good for aluminum alloy

It is also good for aluminum alloy. The strength of the aluminum alloy is three times the strength of plastic, wind pressure strength than plastic two high. Aluminum alloy frame cross-sectional area of only steel 1/3, window frame weight is much lighter. Plastic doors and windows due to the strength of the material and low steel, although the steel lining by adding enhanced, but its wind pressure and watertight performance than the aluminum alloy window two levels. Just because the plastic window steel lining is not in its profile lap angle to connect the complete frame system, window frame, fan four corners and the T-shaped plastic angle of penetration is relatively low, so the high-rise buildings should be used with caution.
