Building materials industry-plastic doors and windows basic situation all the doors and windows of choose
Plastic doors and windows refers to plastic polyvinyl chloride resin without gaining as main raw materials, to join the stabilizer, modification agent, filling agent, by mechanical mixing, plasticizing, extrusion molding of different sections of the structure for the profiles as a door window stem a, according to the size of design cutting profiles, into enhance steel, welding, mount hardware, sealing strip, tops, glass and other become plastic doors and Windows.
1. The performance of wind. In the windows and doors normal closed, wind pressure does not occur in under the action of damage (such as: cracking, panel damaged, local yield, etc) and hardware loose open, the difficulty of the ability of functional disorder.
The national standard GBT7106-2008 “building the air, watertight doors and Windows, classification of wind performance and the testing methods of window of door of the building of wind as level 1 ~ 9 levels. Through profiles in different specifications, shape of placing the increase of the steel, can make the plastic doors and windows for different levels of wind.
2. Air performance. In the Windows and doors normal closed, stop the air permeability of ability. Unit area with air ShenTouLiang (m3 / m2 · h) and units open seam long air ShenTouLiang (m3 / m · h) said, GBT7106-2008 which is divided into 1 ~ 8 class.
3. Watertight performance. In the Windows and doors normal closed, while in the midst of the function, prevent the rain penetration ability. GBT7106-2008 which is divided into 1 ~ 6 level. The structure of the doors and Windows and assembly quality and cooperate with the gap, directly influence the tightness performance and watertight doors and Windows performance.
4. The Lord profiles quality. Profiles of the Lord as the main body of the plastic doors and Windows, its quality directly affect the quality of the plastic doors and Windows. Kdsbuilding expert says According to GB/T8814-2004 “the door, window without gaining with plastic polyvinyl chloride (PVC-U) profile”, the Lord’s key performance indicators are profiles: after heating variation of size (size change will make Windows internal form stress, lead to local damage), the main profile of concussion, aging performance (after aging changes of color of and performance down), the main profile weldability (affect welding Angle destructive).
5. Welding Angle destructive power. Welding Angle is damaging assessment of important index firmness doors and Windows. And the cause of the destructive affect welding Angle, on the one hand, the main profile weldability (and production of the raw materials, the main profile formula and production control about), on the other hand is welding process control of parameters (temperature, pressure, time, accurate positioning).
6. For energy-efficient plastic doors and windows, and the following several key indicator. One is the insulation performance; 2 it is glass sunshade coefficient; 3 it is glass visible light transmission ratio; Four is hollow glass dew point.
Plastic doors and Windows and other products are different, is not directly in the market or manufacturer to buy, but according to the actual situation of the custom, custom needs to incorporate the following factors:
1. According to choose custom size building door window manufacturer, custom manufacturers must have the production of plastic doors and Windows at least configuration (more than three automatic welding machine, double cutting machine, V type saw, clear Angle machine, cistern milling, glass layering saw), doors and Windows excellent quality is based on advanced assembly equipment foundation.
2. In determining the doors and Windows of wind performance, airtight performance, watertight key performance index, should consider building importance, region surrounding environment, air pressure, basic factors such as height, be not gone after blindly high index, quality surplus is also a kind of waste.
3. Quality depends on the use Windows and doors profiles, hardware, sealing strip, tops, glass and other main raw material quality, custom should according to reasonable selecting door window class.
4. The quality of the materials doors and Windows simple method of inspection: the Lord profiles: color uniform; Visible side wall thick: casement Windows: 2.5 mm frequency, push-pull window: frequency 2.2 mm, even open the door: 2.8 mm frequency, sliding door: 2.5 mm frequency; Use hammer hit profiles the plane; With methylene chloride for two hours without basic change.
5. Enhance steel: should use galvanized anti-corrosion processing, thickness: plastic window frequency 1.5 mm, plastic door: frequency 2.0 mm. Glass: without impurities, bubble, level off, across the looking glass objects deformation. Seal tops: hair height consistent, tight, elastic and bottom have strength, bubble is in water, remove and have tiny drops in hand with, left after working, don’t be wet hair. Sealing strip: smooth surface, edge tidy, elastic, hand pull continuously, after let go of basic restorable.
