FRP grating:
FRP grating is made of a glass fiber reinforced materials, unsaturated polyester resin as the matrix, through special processing composite made of a plate-like material with a lot of space, it can be used as a structural material, used as a corrosion environment floor, trench cover, platform, ship decks, stairs, plank and so on.
Grille through a glass fiber braided, resin cast integrally molded together, making the distribution of many of the rules with a rectangular, square spaces FRP grid plate, with two-way mechanical characteristics of the same sex. It can be widely used in petroleum, chemical electronics, electricity, paper, printing and dyeing, electroplating, marine exploration, sewage treatment and other industries working platforms, equipment platforms, drilling platforms, walkways, etc., are ideal for corrosive environments, but also applies to civil construction on facilities.
FRP grating has a long life, low cost, safe, reliable, maintenance-free, as well as beautiful series of advantages. Has been promoting the use of such products in the United States thirty years, FRP grating production and use of sales have been standardized, serialized, the commercialization, the amount is quite large. In the Gulf region, the reconstruction of the Middle East oil fields, the experts, that the use of FRP grating is the most economical and reasonable material, which is being heavily used. FRP grating is also being used in Asia, Singapore, Taiwan and other regions.
Actual size according to customer needs, can be cut stitching. Use stainless steel grille snaps between the glass plates require stitching connection.
FRP grating characteristics:
1 anti-corrosion: a very superior acid and alkali resistance, and many other organic solvents and salts gas, corrosive liquid medium can, in the field of preservation has incomparable superiority. According to the actual requirements of the case, can be selected and used phthalic economic type, isophthalic, vinyl type resin as the matrix material.
2 light weight, high strength, and easy to cut, the installation: the resin and because it is made of glass fiber composite with a density of not less than 2 kg per cubic centimeters, only a quarter of steel, aluminum 2 / 3. Its strength is 10 times of rigid PVC, aluminum and absolute intensity level than ordinary steel. Its light weight, can greatly reduce the base support, thereby reducing the material cost of the project. Its cut is easy to install, no flare and large lifting equipment, only a small amount of manual and electric tools, making the installation costs are greatly reduced.
3 anti-aging: life in more than 30 years.
4 flame: Common flame retardant grill flame propagation rate (ASTM E-84) does not exceed 25; flame retardant vinyl grill senior propagation rate does not exceed 10. Oxygen index of not less than 28 (GB 8924).
- Q: Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
- Press the bottom width. Plastic steel profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion of the profile. 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.
- Q: 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.
- 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: The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
- Allows the use of steel profiles. The provisions of the doors and windows with the number of layers does not matter. Now energy-saving requirements, no matter what material, as long as the energy-saving requirements on the line. Aluminum need to use heat type, more expensive, so the use of steel is more common.
- Q: What is the quality of plastic steel profiles in the end?
- 08 years to now has been doing the money, it began to have no conch and Shide famous, but it is higher than the other brands, the reason it is a high proportion of plastic, that is less talc powder, the other three sealed pad The bridge is split, so that the fan does not account for the proportion. Speaking of two-color co-extruded, it is the technology is ASA technology is always the most leading, there is no fade, and gorgeous and glossy, which is other profiles can not be compared, I used to vote in the tender angle, , Shide, Zhongda, Huaan, ... .... 10 years did appear broken material situation, has not yet been found.
- Q: How plastic embossed profiles are made
- Preheat To improve the processing performance of the molding compound and shorten the molding cycle, etc., the molding of the molding material before the first heating operation.
- Q: Plastic steel window profile specifications models which
- Plastic window is a form of window that is actively promoted by the state in the mid-1990s after the wood, iron and aluminum windows. Because of its low price, performance and price is better, is still widely used.
- Q: 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.
- Q: PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages?
- PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages? PVC is PVC, PVC in all plastics, the price is the cheapest, the advantage is cheap, toughness is better, the disadvantage is PVC Resin powder can not be used directly, but to add the relevant additives and stabilizers and auxiliary materials into, and then to produce products, the extrusion screw and barrel have special requirements. Because the plasticization of the relationship, so the equipment targeted.
- Q: What is the difference between plastic doors and windows and steel doors and windows?
- PVC plastic doors and windows in the country is widely known as the steel doors and windows, plastic doors and windows is based on polyvinyl chloride (PVC) resin as the main raw material, with a certain percentage of stabilizers, colorants, fillers, impact modifier, Absorbent (shielding agent) and other additives, the extrusion of the material.
