Door and window sealing strip industry will usher in a new spring

The development history of doors and windows is also the development history of sealing strips. The replacement of doors and windows also drives the replacement of sealing strips. However, the Chinese-style production concept is worthy of our deep consideration - blindly reducing costs and competing at low prices. There are many big brands in the door and window accessories industry, such as Jianlang, Yang's, Noto, Sigiriya... But there are very few big brands of sealing strips. It's not our technical problem, it's a production concept problem. I hope that the bosses of the sealing strip industry will insist on doing their best and not be dragged down by the low prices of small manufacturers. For the future of China's doors and windows, they will be more responsible for themselves. To be a veritable big brand in the door and window accessories industry. 1. The era of natural rubber seals In the mid-1990s, steel doors and windows, ordinary aluminum alloy doors and windows, and ordinary wooden windows used to occupy almost all the shares of Chinese doors and windows. At that time, the sealing strip was the era of natural rubber, the Chinese-style small workshop production mode, the Chinese-style cost reduction, coupled with the lack of natural rubber itself, it was not resistant to aging in the natural environment, cracked and hardened in a few months, Fractured, and finally, at the same time that steel doors and windows were banned by the state, they gradually faded out of the market... 2. PVC polyvinyl chloride sealing strip In the late 1990s, plastic steel windows were synonymous with noble doors and windows. There was a story that a provincial official in Hebei Province personally went to a plastic steel profile factory to queue for half a month before buying profiles. Building doors and windows have ushered in the era of plastic steel, and the country has begun to promote the use of PVC sealing strips on sealing strips. PVC sealing strips have become the darling of plastic steel door and window sealing strips because they do not crack and are easy to weld. However, only 2-3 years later, the problem appeared. The precipitation of PVC plasticizer, the industry problem that has plagued the world, is clearly reflected in the PVC sealing strip. Due to the precipitation of plasticizers, the rubber strips contaminate the profiles, the length shrinks, the broken section shrinks, and the sealing is not tight. The Chinese-style small workshop processing, Chinese-style cost reduction, and Chinese-style low-price competition have led to the application of inferior plasticizers and recycled PVC, which has aggravated the problems of the entire sealing strip industry. Therefore, the doomsday of PVC sealing strips began to appear. 3. EPDM EPDM sealing strip In early 2000, the state issued a civil order to restrict the use of polyvinyl chloride and PVC sealing strips, and promoted the use of EPDM EPDM sealing strips and MVQ silicone rubber sealing strips. EPDM sealing strip, a high-grade sealing strip used in cars and trains, has finally been adopted by the construction industry. In fact, the popular use of doors and windows was after 2002. At that time, doors and windows gradually entered the period of broken bridge aluminum alloy, and EPDM became synonymous with high-end sealing strips due to its superior physical properties and good aging resistance. In 2011, under the influence of international oil and other factors, the price of ethylene propylene has skyrocketed, and the cold winter of EPDM sealing strips has come, so Chinese wisdom has come, and reclaimed rubber has begun to be widely used. The entire sealing strip market is in chaos, and a good sealing strip is hard to find. A certain county in China is the base of domestic seals, and about 70% of China's EPDM building seals come from its county. There is a boss of the same industry in this county. He once chatted with me and said, we are very proud now. 70% of the ethylene-propylene sealant in the country comes from us. We are almost monopolizing the trend. After listening to it, I was at a loss. There were almost no brands. It was completely low-price competition. I feel sad, sad for the poor reputation of EPDM in the same industry, and sad for the future of the seal... 4. MVQ silicone rubber sealing strip MVQ silicone rubber sealing strip is not so much the latest sealing strip material. In fact, it is not the case. Silicone rubber has a history of decades in China. In the past few years, it was indeed the pride of rubber, and it was very delicate. In recent years, the cost has been gradually reduced, and it has been gradually applied to building sealing. The advantage of silicone rubber for sealing over ethylene-propylene rubber is that it has better compression deformation performance than ethylene-propylene rubber, so the sealing performance is better, and from the principle of time-temperature equivalence, the temperature resistance of silicone ru

The plastic doors and windows market has different advantages and disadvantages, and the sealing strip is bucking the trend

In the past use, the quality and service life of plastic doors and windows have been greatly affected due to the influence of low-performance and poor-quality sealing materials, and many quality problems have occurred, which have seriously damaged the reputation of the business. Especially when used in doors and windows of construction projects, it becomes hard and brittle, loses elasticity and sealing function, and becomes sticky and "oil seeps". The occurrence of this phenomenon is attributable to the fact that enterprises ignore the introduction and development of door and window accessories while improving the grade and performance of plastic doors and windows, resulting in the development of sealing materials far lagging behind the development of plastic doors and windows. It is gratifying that high-grade and high-quality door and window accessories, especially door and window sealing materials, are being accepted by everyone, and gradually enter the door and window market. Material condition of plastic door and window sealing strip At present, the materials of sealing strips used abroad mainly include NBR, EPDM, thermoplastic elastomer (TPE), polyurethane elastomer (P), silicone rubber, etc. The usage rate of EPDM rubber is high, reaching more than 60%. Analysis on the Development Status of Plastic Door and Window Sealing Materials in my country In recent years, the market share of plasticized polyvinyl chloride sealing strips in the domestic door and window sealing materials market has reached more than 90%, while the modified high polymerized polyvinyl chloride and thermoplastic elastomer sealing strips recommended by relevant industry departments The occupancy rate is extremely low, and most of them are concentrated in the surrounding areas of Beijing. EPDM rubber material was developed in my country by Beijing Chemical Industry Research Institute in the 1960s, but its application and development in doors and windows was only put on the agenda in the mid-1990s. The product factory was developed and passed the acceptance of the relevant experts of the Ministry of Construction in the latter half of the same year. It is currently in the stage of mass production, but only some high-end door and window manufacturers in China are using it. Compared with similar foreign products, the market price of domestic EPDM rubber sealing strip is about 40% lower, but the development is still slow. Only the cost saving is considered, and the comprehensive benefits brought by the use of high-priced and high-quality sealing materials are not considered. Sectional Design of Sealant Strip and Process Status of Mold Making Due to the late development of domestic plastic door and window sealing strips, the initial cross-sectional shape is relatively simple and limited to the "K"-shaped strip used for glass bead sealing, the large spoon strip used for window frame (fan) sealing, and the small "0" used for gauze fan. "Article, the variety is relatively single. On the contrary, with the development of plastic doors and windows, the production of foreign sealing strips has reached serialization and scale. The design of each product section meets the requirements of relevant functions, and the cooperation with the corresponding profiles is almost perfect. The report shows that in recent years, with the introduction of foreign door and window manufacturing technology, the cross-sectional shape and variety of domestic sealing strips have also undergone great changes. First, the degree of attention to the sealing material is not enough, and finally, although the shape of the produced product is close to the designed shape, there are still some defects in the use function, such as the large gap of the matching part, the amount of lamination and overlap of the finished product. The relevant requirements are not met, so that some quality problems will inevitably occur in the process of use. The appearance of this phenomenon is not only affected by the above factors, but also affected by the raw materials used, such as the processability and expansion rate of the materials. EPDM rubber is a kind of sealing material with excellent comprehensive performance. It not only has excellent physical properties, but also has good processing performance and small expansion coefficient. The sealing strip made of this material is almost the same as the design requirements. This is also an important reason for the rapid development of EPDM in recent years.

How to seal doors and windows in winter to keep warm

The winter solstice is over, and the coldest time of the year is here. Many friends complained that the heating and air conditioning were turned on at home, but it was still not warm. In the final analysis, it is because the doors and windows are leaking. That's true, near windows and patios, it's a lot cooler. Therefore, some experts remind all owners to seal doors and windows well in winter to prevent indoor air leakage and temperature loss. Causes of air leaks in windows Good sealing is one of the indicators to measure the quality of doors and windows. Many people report that the main reasons for the leakage of doors and windows in the home can be attributed to uneven profiles, aging sealing strips, cracks between the frame and the wall, and aging hardware. In addition, the doors and windows of some owners' homes have deviations in the initial measurement, such as the size of the window sash is too small and cannot be tightly fitted with the window frame, which also buried hidden dangers for air leakage. Due to the air leakage problem caused by the problem of the sealing strip, the owner can purchase the corresponding sealing strip according to the specifications and models of doors and windows, and replace it by himself. For air leakage caused by other reasons, the owner needs to contact professional technicians for overhaul. The sealing effect depends on the profile and the opening method The price of aluminum profiles for thermal insulation and broken bridges is expensive, but the thermal insulation, heat insulation and sealing effects are better than those of plastic steel profiles. In addition, consumers are advised to choose an exterior window with a double-layer insulating glass structure, which has a certain gap between the glass and the glass, so it has good thermal insulation, heat insulation and sound insulation performance. In terms of the opening method of windows, the sealing effect of casement windows is generally better than that of sliding windows. The reason is that casement windows are generally sealed with sealing strips, while sliding doors and windows are generally sealed with wool strips, and the sealing effect of rubber strips is better than that of wool strips. In addition, the opening fan part of the casement window is locked and sealed with multi-lock point hardware, and the sealing effect is better. Sliding windows are generally locked with hook locks or knock locks, and the sealing effect is poor.
