Environmental protection building materials of choice for plastic doors and Windows profile
Wen injection tooling/VIP has good heat preservation and heat insulation and sealing good new plastic doors and Windows as China's energy conservation and emissions reduction actively expand and more and more investors varieties increased attention to Windows and doors.
With the expert points out, will become the industry investment hot spot is plastic with good sex of energy-saving building materials.
in many varieties of plastic building materials, plastic doors and Windows profile because a good industrial foundation, wide prospect of market and investors of all ages.
Plastic material after years of development, now has become the most mature technology, the application in plastic building materials is one of the best varieties of plastic building materials.
plastic doors and Windows of double glass Windows under the heat transfer coefficient k value up to 3, can meet the hot summer and cold winter region, hot summer and warm winter area and cold region most of the energy conservation and environmental protection building requirements.
And ordinary aluminium alloy window, even if is low
E hollow glass, its value can only be 3 k.
5 to 3.
Therefore, to meet the requirements of the same k value, plastic doors and Windows can choose cheaper matching glass, thus reduce the doors and Windows engineering cost, and become the energy conservation and environmental protection building materials.
experiments show that plastic doors and Windows of the single glass window heat transfer coefficient k value can be up to 5 below, is a kind of energy conservation and environmental protection building materials, can meet most of the energy conservation and environmental protection requirements in the area with hot summer and warm winter.
in the inland border in the north of China, there are more than more than forty percent of new housing in the plastic doors and Windows, and dalian and Qingdao is the application of more than 80% of plastic doors and Windows.
The development of building industry in China is still widely used to promote the rapid development of the plastic material with, with the great market potential, new product can attract more and more investment.
Its highly efficient heat preservation, sound insulation and moisture characteristics, coupled with a rich source of raw materials, can replace the traditional steel with wood and other building materials, in recent years there has been widely used in construction market.
If single in order to improve the market share, China's energy conservation and emissions reduction work of is on the sealing performance is good heat preservation and heat insulation with new plastic doors and Windows.
in & other;
Five-year & throughout;
Planning rules related to building energy efficiency building energy-saving materials and technology is expected to market capacity of up to tens of thousands of one hundred million yuan, this will be significant to the development of energy efficient and environmentally friendly plastic building materials market space.
plastic doors and Windows profile has the following advantages in terms of heat transfer, plastic doors and Windows material belongs to a poor conductor of heat, its coefficient of thermal conductivity is only 1/250 of 1/360 of the steel, aluminum, has good heat preservation and heat insulation performance.
At the same time, plastic doors and Windows with different profile for chamber structure, it is composed of multiple independent airtight air thermal insulation layer, make full use of the thermal insulation performance of the air, make its plastic doors and Windows to further reduce the overall heat transfer rate.
in the airtight performance, plastic door and window or door material, is through the molten weld between window frame and window sash is a whole, there is no gap between bearing material, put an end to the air through the horizontal and vertical material joining together the possibility of a corner.
plastic doors and Windows processing size and high processing precision, lap joint design is exquisite, the sash in the assembly, all the gaps are equipped with sealing strip or sealing wool top.
Glass Mosaic in the layering and casement combination into the slots, two side are made of elastic rubber seal.
Plastic doors and Windows of push-pull window sash buckle in push-pull window frame rail, fan and casing by wool top seal.
Push and pull between fan, also by two of wool top seal.
Casement Windows between window frame and window sash is through the sealing strip, and casement window frame and window sash and box Ting have strip seal on both sides in indoor and outdoor.
in addition, plastic doors and Windows installation time, require the use of flexible support between wall and window frames, with foam rubber seal.
At the same time, the corresponding parts in the window frame and window sash has the pressure balance hole and drain, further improve the airtight performance of the window.
in the shade, sun radiate to heat up the influence of building energy consumption is very big, summer sun radiate to increase the cooling load, the winter sun radiate to reduce the heating load.
Therefore, different regions, different seasons, energy conservation and environmental protection construction of plastic doors and Windows and the surrounding sunshade products demand different shade.
experiments have proved that as long as the production and installation in strict accordance with the specification, plastic doors and Windows of push-pull window airtight performance can reach 1.
5, casement Windows air-tightness can reach 0.
Even with the general performance of push-pull window, the airtight performance can satisfy the hot summer and warm winter area residential building energy conservation design standard 'and' hot summer and cold winter area residential building energy conservation design standard 'requirement, the real energy conservation and environmental protection building materials.
