The main features of steel profiles
- Plastic steel profile referred to as steel, the main chemical composition is PVC, it is also called PVC profiles. Is widely used as a new type of building materials, because of its physical properties such as rigidity, flexibility, corrosion resistance, excellent anti-aging properties, is usually used as copper, zinc, aluminum and other non-ferrous metals excellent substitutes.s
How plastic embossed profiles are made
- Preloading To improve the quality of the product and improve the molding efficiency, the powder or fibrous molding compound is pre-pressed into a certain shape.s
The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
- The state of high-rise residential building doors and windows materials are not allowed to use steel profiles should be allowed. We are a lot of these are more than 20 layers of plastic steel `` also used.s
The development of steel profiles
- From white to color: color profiles change the steel doors and windows in the past monotonous white, with the building as a whole with the perfect color. Color profiles market share rose rapidly, especially in some high-end residential area widely used.s
PVC plastic profiles dip in the seam, how to deal with seamless docking
- Stabilizer too much or too little stabilizer is to inhibit the degradation, or with the release of hydrogen chloride reaction and to prevent the discoloration of PVC processing. Stabilizer according to the different types of different, but the total point, the amount of excessive will delay the material of the plasticization time so that the material export mold when the plastic is not, the formula system between the molecules are not fully dissolved, Its intermolecular structure is not strong cause. And the amount of too little will result in the formulation of relatively low molecular weight degradation or decomposition (also can be said to be plasticized), the stability of the intermolecular structure of the various components of the damage. So the amount of stabilizer will also affect the impact strength of the profile, too much or too little will cause the profile strength caused by the phenomenon of brittle profile.s
Steel windows and aluminum windows compare which is more expensive
- Air tightness:
Plastic window due to the box, fan components are welded, so the air tightness should be slightly better than the spiral of the aluminum alloy window, but the aluminum window profile height accuracy, box, fan with more closely, so the two are still in a Level level.
3, the insulation performance: aluminum window insulation performance as plastic window is good, but the ratio of the two window heat transfer ratio is only 1.36 times (single window) and 1.44 times (single frame double glass).s
What is the steel profile?
- Simply put the profile is installed into a window that can still be seen after the outer surface. Such as the large and small faces of the box. While the middle glass trough installed glass and pressed after the invisible, that is non-visible surface.s
What belongs to plastic profiles
- Plastic profile additives four: processing aids
Auxiliaries are mainly developed to improve the performance of plastic molding. Plastic profile processing temperature and decomposition temperature is close, poor mobility, easy to stick in the equipment on the coking, so the production of plastic profiles need to add a certain amount of processing aids to overcome the defects of plastic profiles themselves.
Plastic profile additive five: light stabilizer
The light stabilizer can inhibit the photooxidation degradation reaction of the polymer by shielding and absorbing ultraviolet rays, quenching and exciting energy to capture free radicals, so as to give the products a good light stabilizing effect and prolong their service life.
Plastic profile additives six: filler
The filler is a solid additive that is different in composition and structure from plastic, also known as fillers. To improve the physical and mechanical properties of plastic and reduce the cost of plastic has a significant effect and economic value. Plastic profile production formula to add filler, plastic profiles can be heated after the size of the change in the rate of change, increased impact strength, increased rigidity, while also reducing production costs.s
