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.s
It is good for aluminum alloy
- Aluminum alloy doors and windows of the performance / price ratio is higher than the steel doors and windows. Foreign aluminum doors and windows price is 1.5 times the steel doors and windows, that is, steel and steel doors and windows cheaper than the aluminum doors and windows 33% cheaper. However, the situation in our country is the opposite. Generally on the market, single glass plastic steel doors and windows than aluminum alloy doors and windows prices 25 to 33%; hollow double glass plastic doors and windows than the price of aluminum windows 36 to 44%, of course, these two types of steel doors and windows than aluminum alloy doors and windows insulation performance Well, but other properties of steel doors and windows are not as good as aluminum doors and windows. Hollow double glass aluminum doors and windows than the price of single glass steel doors and windows about 25% higher, however, the former insulation and sound insulation and other properties are better than the latter, for the same type of structure of the flat window, in the aluminum window (K = 2.8), the latter's price is about 24% higher than that of the former. However, the high strength and high strength of the former is higher than that of the former. Performance, excellent corrosion resistance (spray paint) and decorative effects (metal texture and non-metallic texture and other colors and boxes, window type box can be indoor and outdoor two colors), long life and other comprehensive performance is far better In the latter.s
Specification for steel profiles
- At present, the smallest domestic steel profile section for the 60 series, a screw-connected window called steel-plastic composite doors and windows,s
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.s
What is the difference between plastic doors and windows and steel doors and windows?
- According to the characteristics of profiles, the profiles are roughly divided into European and American two.
European doors and windows of its characteristics are: profile formulations still use the traditional lead salt heat stabilizer, a small number of countries and enterprises began to use environmentally friendly organic tin heat stabilizer; main section of the profile profile is generally designed for three or four main chamber, The total number of chambers to 6 to 8, wall thickness is generally 2.5 ~ 3.0mm.
Doors and windows with fan-fan frame structure, fan section larger, with pulley, can be removed; built-in glass, dry mosaic; window open in the foreign under the hanging window-based, a small amount of sliding window.
American doors and windows: the main formula for the use of environmentally friendly organic tin heat stabilizer, to avoid the production, processing, use of lead salt toxicity of the drawbacks; development for the multi-cavity section, the second is to reduce the profile wall thickness, 1.80mm; while increasing the number of internal reinforced steel and the chamber, the chamber generally have 9 to 13. In addition to reducing the strength of profiles, but also improve the thermal insulation and sound insulation effect.
The sliding window for the frame package fan, improved the sealing and safety performance, cancel the fan pulley, reduce the fan section at the same time, the window lighting performance has been improved. Developed a standard installation method for pulling windows and new mounting wings.s
Plastic profile brittle extrusion process unreasonable reasons
- Head pressure is insufficient
On the one hand and mold design; the other is the proportion of the feed and temperature settings, the pressure is insufficient, the material density is poor, it will become loose tissue plastic brittle phenomenon, then adjust the metering feed speed And extrusion screw speed so that the head pressure control in the 25Mpa-35Mpa between.s
How many meters of a conch plastic steel profile
- Plastic specifications of a lot of steel, do not know what you want to know? But each type of material has a standard weight of rice, their own to know, for example: Conch 60 two-track sliding box weight is 1.22kg, then 1000kg divided by 1.22 = 819 meterss
