Several advantages of glass steel pipeline with insulation:
(1) corrosion resistance: chemically inert material,excellent corrosion resistance, and can according to thedifferent choice of corroded pipeline conveying medium.
(2) high mechanical strength: water pressure resistance,resistance to external pressure strength and impact strength were good and according to requirements of thedesign and manufacture of pressure pipes and pipe fittings.
(3) temperature adaptability: use temperature range:more than -70 degrees Celsius lower than 250 degrees Celsius, the freezing medium pipeline without crack.
(4) small fluid resistance: pipeline smooth inner wall,roughness coefficient is 0.0084, the same flow, pipe diameter can be reduced.
(5) light weight, long service life, light weight, convenient transportation, low cost, no maintenance, the service life of 50 years or more.
- Q: The development of steel profiles
- China's steel production capacity has reached 5 million tons / year. Most manufacturers can not fully play the capacity, there is a serious overproduction and homogenization of competition. China's steel profiles common national standard is GB / 8814-2004, access to national inspection-free enterprises are also referred to this standard production. Different from Europe and the United States, China's single type of profiles, the market is the bulk of the 60MM Pingkai doors and windows series of profiles and 80MM push-pull series of doors and windows profiles. The above two specifications account for more than 80% of the total consumption.
- Q: Plastic steel profiles how to open the mouth of the best illustration and the formula there are cross-port V to answer to a comprehensive ah
- Plastic profiles open V mouth has a special V mouth saw, with a manual cutting machine are not allowed, angle, V port depth can not be determined.
- 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: 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: What is the material of steel
- In the building construction is mainly used for sliding, sliding doors and windows, fence, pipe and ceiling material applications, through the new process is also widely used in automotive engine protection board, not only light weight, and good toughness, with just fine Nature, and sometimes also known as alloy steel.
- Q: Is the powder produced when the crushed plastic is crushed?
- 1, plastic shredders and power units to be installed firmly. If you need plastic crusher long-term fixed operation, it should be fixed on the basis of cement; if you need plastic crusher flow operation, the unit should be installed in the angle made of iron on the base, and to ensure that the power machine (diesel or motor) and plastic The pulley groove of the crusher is in the same plane of rotation. 2, after the installation of plastic crusher to check the Department of fasteners fastening, if loose to be given to tighten. Also check the belt tightness is appropriate. 3, plastic shredder before starting, first hand rotation of the rotor, check the claws, hammer and rotor operation is flexible and reliable, broken room with or without collision phenomenon, whether the direction of rotation of the rotor and arrows in the same direction, Plastic crusher lubrication is good. 4, do not casually replace the pulley, to prevent the speed is too high to cause the explosion chamber explosion, or too low speed affect the efficiency of the pulverizer. 5, plastic shredder should be maintained after the first start idle 2 ~ 3min, no abnormal phenomenon after feeding work. 6, the work should always pay attention to the operation of the plastic crusher, first of all, to be uniform to prevent the blockage of waste room; Second, do not work for a long time overload. If you find a vibration, noise, bearing and body temperature is too high, such as spraying out of the phenomenon, should immediately stop checking, troubleshooting can continue to work.
- Q: 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.
- Q: Plastic doors and windows and plastic doors and windows have anything to do
- 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. Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
- Q: What belongs to plastic profiles
- Plastic profiles are used more: window frames, staircase handrails, troughs, wall feet, shaped tubes and so on. Raw materials are mainly hard PVC, a few are semi-hard PVC, soft PVC, polyurethane low foam and other materials. Plastic profiles with its excellent thermal insulation performance is listed as one of China's key development of building materials. In the production of plastic profiles, the need to pay attention to what problems in order to ensure the quality of profiles and technology.
- Q: PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages?
- ABS weather resistance is poor, the proportion of light, chemical resistance is poor, but if the ABS and PVC blending modified into PVC / ABS alloy pellets, you can combine the advantages of two products in one, the price is cheap, the current price 14500-17000 yuan / ton.
