Product Description:

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: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:Steel windows and aluminum windows compare which is more expensive
Wind pressure strength and watertightness: Plastic windows due to the strength and rigidity of the material is low, although through the processing of steel to enhance, but its wind pressure and watertight performance than the aluminum window about two levels. Moreover, due to the steel window steel lining steel is not in its profile cavity angle into a complete frame system, window frame, fan four corners and T-shaped plastic welding angle strength is relatively low, according to the end of 1998 Shanghai enterprises inspection 425 Batch steel window three examples of the situation after the serious analysis of the "plastic window in the high - rise buildings should be used with caution.
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: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.
Q:How to identify the installation of plastic or plastic
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: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:The main features of steel profiles
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:Plastic doors and windows and plastic windows do not like?
Plastic doors and windows that use U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features. Plastic doors and windows are made of steel and steel profiles of doors and windows, steel profiles are made of plastic and steel profiles made of mixed.
Q:It is good for aluminum alloy
Aluminum alloy high temperature, non-flammable; is a good conductor, lightning can be anti-static; recyclable, environmentally friendly. Plastic is not high temperature, combustion; is the insulator, but need anti-static; degradation is slow, can not be recycled, slow combustion will release toxic gases, environmental impact.
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.
