What are uPVC doors of good quality?

01/04/2014 2333 lượt xem
UPVC doors were born in European countries more than 60 years ago. Thanks to the superior features of sound, heat insulation, uPVC doors have been quickly used in many countries around the world.
Door market in Vietnam 10 years ago, in addition to the traditional doors such as wooden doors, aluminum doors only cover rain, sunshades, windows have appeared, doors uPVC soundproof, high heat and consumer preferences. In addition to the modern factories have invested in high automation equipment line, advanced technology and production process, with the "hundreds of flower bloom" has appeared more production facilities. and trading this item. In particular, many small workshops are handcrafted, only invest in equipment as thin as cutting machines, welding machines also advertise uPVC doors called na na, which mainly imitates the trade. famous brand. However, not all products are good and provide sound insulation, which makes many people feel anxious when choosing.
 
 
 
 
Kommerling's Greenline standard
 
- Greenline is a standard system for lead-free stabilizers in uPVC profiles, environmentally friendly, non-toxic to the user.
- Greenline products are high quality products:
 
Contains no lead, friendly to the environment
The compounds are formed without the need for lubricating oil or the support of mixing
High thermal insulation
High stability
- All Greenline door products are stable and stable under all weather conditions.
- Greenline helps increase the value of the product without increasing costs.
Since 2001, Kommerling has used Zinc - Calcium instead of Lead. Since 2003, the company has started producing lead-free plastic bars and in 2004, the Greenline standard was applied to the global production system. - With the Greenline standard, Kommerling acts as a responsible leader in the environment and people in a sustainable way.
 
 
 
UPVC doors, in addition to the advantages of sound insulation, thermal insulation, noise protection, energy saving cooling and heating, also bring the house elegant, luxurious and modern. But to achieve these features and maintain the beauty of durability, requires uPVC profile bar not only beautiful appearance but the material must meet standards, otherwise the product will quickly degrade under gas conditions. harsh postures in our country. Meanwhile, many Vietnamese consumers often only care about the cost of the product but ignored the quality factor. In order to select the uPVC doors of good quality, to ensure the sound insulation, you need to pay attention to the elements constituting products from profile bars, metal accessories, glass boxes to rubber gaskets. .
 
Profile bar is an important part of door structure, shaped from uPVC plastic, different from ordinary plastic. uPVC is Polyvinyl Chloride Hard is denatured by its components: Acrylic Polymers for strong resin, strong impact resistance; Stabilizers help the plastic to withstand the effects of heat and ultraviolet light; Antioxidants and yellowing additives; beeswax to make the profile bar has a glossy surface. These components make uPVC material curvature, shrinkage, no aging or yellowing in conditions of solar radiation, high fire retardancy and keep the original beauty throughout the history. .
 
In the world, large multinational corporations in the production and supply of uPVC profiles can be mentioned as HT TROPLAST AG with well-known brands such as Kommerling, KBE, Trocal or Veka companies. , Rehau, Aluplast, Tessenderlo ... originated from Europe. HT TROPLAST AG is Europe's largest producer with 22% and more than 20% of the world market share (Veka accounts for 17%, Rehau accounts for 14% of Europe's market share). Profile of HT TROPLAST AG is manufactured in factories in many parts of the world such as Germany, Russia, France, Italy, Spain, USA and China. specific characteristics of each area. In Europe, the profile bar is made up of more cavities to resist cold weather. As for the Asian region, due to the hot tropical climate should be added antioxidant additives and yellowing.
Kommerling belongs to HT TROPLAST AG is a leading brand in the production of profile bar "Greenline". This is the standard system for lead-free stabilizers in uPVC profiles, environmentally friendly, non-toxic to the user. Lead is a heavy metal toxic to the human body. Lead can enter the body through the respiratory tract and mouth, causing pain in the eyes, throat, nose, headache, memory loss, insomnia ... Frequent exposure to lead lead to lead poisoning. weight loss, nausea, abdominal pain, increased risk of high blood pressure, in the long run will cause kidney disease, anemia and brain damage. As a result, European countries have banned the use of lead in the production of profile bars instead of zinc-calcium synthetics to avoid human toxicity and environmental friendliness. However, in some Asian countries and in Vietnam, lead metal is not banned for use in production, so most Chinese or some other countries still use Lead as an additive in production. Lead-based profiles are cheaper than zinc-calcium compounds. In addition, these suppliers reduce expensive additives and increase the cost of cheap powder to reduce the cost of the product, so the fast profile is stained yellow, scratches, brittle fracture, welded fracture and can also be deformed. The reinforced steel core inside the profile bar is sometimes thinned and does not use stainless steel, so the profile bar is weak and the rusted steel loses its effect. It is difficult to distinguish uPVC profiles at the very early time, even bonded marks such as glossy surfaces are only exposed after a period of use.
 
UPVC doors were first invented and used in European countries, so the profile production technology of these countries is considered as the most advanced today with its own know-how and long experience. With the trend of globalization, multinational corporations have built profile plants in many parts of the world. Profiles made from these plants are standard quality and safety for the user. Therefore, you do not have to worry about where the product is produced, but only the products manufactured by the company. With the prestige brands, experience and market share as: Kommerling, KBE, Trocal, Aluplast ... you can be completely assured about the quality of products.
 
 
 
Besides choosing the good quality profile, when buying uPVC products you also need to pay attention to the origin of the metal accessories including multi point, 3D hinges, special lock ... Do door often work Mechanical, such as open, the accessory should be made of stainless steel, high durability. Currently, there are a number of manufacturers cloning accessories with quality not sure to lower the cost of products. But after a period of use, this kind of accessories will reveal the disadvantages such as rust, loose, make the door not close, reduce the sound insulation, insulation. Therefore, you should choose the products that use metal fittings of the leading companies in Europe. With products from China, you may encounter counterfeit goods, counterfeit quality by the manufacturer of the craft.
 
Glass is also an important component of uPVC doors and one can use a single glass or glass box according to need. But for sound insulation, good insulation should use glass box. In addition, the glass box with safety glasses, tempered glass will ensure the safety of users and do not have to make the iron against intrusion. Glass box production must always be in closed chamber conditions, low humidity, to avoid condensation. Inside the glass box is injected inert gas (Argon gas, not the vacuum as many people mistaken) to balance the pressure and reduce the transmission of sound, heat transfer. Safety glass, tempered glass should be standard and strictly tested before putting into production glass box. There are many suppliers of toughened glass but only semi-hard or damaged to damage consumers. Therefore, for tempered glass, it should be passed through the glass-heat tester after I (Heat-Soak-Test). During inspection, broken glass panels will break and be eliminated to minimize the risk of explosions during use. Currently in our country, only a few large companies invest in modern glass production line and control the production process in accordance with international standards.
 
The rubber gasket is also an important detail contributing to ensure the tightness of uPVC doors. If the gypsum is not good will quickly aging, loss of elasticity and shortness of the podium only after a short time of use.
In addition to the components that make up the product, the production and installation is also very important for uPVC doors to gain the advantages of the door because it has many different points compared to other doors. Production quality must be controlled. As for the installation, to ensure the tightness, the foam is sprayed into the gap between the wall and the door frame and Silicon plaster outside the door. This operation is very important, because if not careful, the process will be easy to rain through the door. In addition, because the braces and glasses are very close together during the installation if the calibration is not accurate, the door is prone to glass cracking easy to use. Because the uPVC door can be calibrated by hinges, you can learn how to adjust the door so that the door is always tight and good sound insulation.
