What are the materials of door and window sealing strips: 1. Rubber and plastic materials: Rubber is a kind of PVC, the processing equipment in brief, and investment in less, the material is very easy, the colour of the finished product, also can recover, using rate is very high, so all the capital in low, rubber with plastic, and even with blunt nose smell, its flexibility, patience and a bad weather in stretching the future reply slowly, And it's highly affected by temperature. 2, EPDM EPDM: Epdm has the very good ozone resistance and oxidation resistance, good heat resistance and low temperature characteristics and so on many merits, the other, but also has good electricity, mutatis mutandis, the sex and outstanding stress-strain characteristics and so on merits, out of goods but also in safe, and dimensional accuracy is very high, but the epdm color comparison list one by one, since a self-adhesive stick with each function is poor. 3, covering type sealing rubber strip: The sealing strip function is very well, and is energy-saving, environmental protection international three generations of seal products, by the strength of the thermosetting core and outer cortex and not of the same material system, to ensure the sealing strip long time use in different environment and cause of deflation and deformation, the strip has significantly, mutatis mutandis, the effect of sound insulation noise reduction and very superior heat preservation and heat insulation. 4, plastic steel doors and Windows sealing rubber strip: Window of model steel door sealing strip is in recent years in terms of use in a wide range of new generation of Windows and doors, it is usually the doors and Windows sealing strip corrosion and weather resistance function is very good, and have the effect of the noise reduction thermal insulation, the appearance of this kind of window of model steel door sealing strip is very light, has very good waterproof sealing function, and function of the house of beautiful decoration. Above is a brief introduction about what are the doors and Windows sealing strip material, believe that through the above introduction, you will have further knowledge of doors and Windows sealing strip material and understanding, and of course selection at the end of the doors and Windows sealing strip, the next step is to be installed, what what are the precautions for sealing strip prior to installation of the window? Take a look at the following introduction: Precautions before installation of window seals: 1, before the installation of glass to carefully remove debris in the notch, such as mortar, brick debris, wood, etc., the glass should be carefully placed in the center, to ensure that the clearance on both sides of the uniform, and timely more positive fixed, prevent collision displacement, deviation from the notch center. 2, rubber seal can not be pulled too tight, cutting length than assembly length 2O-3OMM, installation should be embedded in place, the surface is straight, and glass, glass notch close contact, so that the glass surrounding force uniform, in the corner rubber strip should be bevel disconnected, and in the disconnect glue bonding firm. 3. When sealant is used to fix the glass, the glass should be squeezed with rubber strip or rubber block first, and the glue injection gap should be set aside. The glue injection depth should be no less than 5mm. 4, the installation part of the wool is generally in the window (door) fan, box fan around or seal bridge (block), enhance the seal between the box and the fan. 5, the specification of the wool is an important factor affecting the sliding doors and Windows and watertight performance, is also an important factor affecting the doors and Windows switch force, the wool specification is too large or vertical hair is too high, not only difficult assembly, but also make the doors and Windows movement resistance increases, especially when opening the initial resistance and closing the final resistance in place is larger. 6, the specification is too small, or the vertical wool height is not enough, easy to come out of the groove, the sealing performance of doors and Windows greatly reduce the table picture, the wool needs to be siliconized, the quality of the appearance of the wool for the surface is straight, the bottom plate and the vertical wool is smooth, no bending, no hemp on the bottom plate, in line with the provisions of 0.2mm.

1, automatic door must understand the common problems :(1) automatic door track and hanging wheel can not be refueled; Otherwise, the pulley on the hanger has a rolling problem and causes the door to impact.

After the two sessions, the property market regulation has become a topic of concern. With the introduction of purchase restriction or upgrade policies in various provinces and cities, real estate sales may decline. As a downstream industry of real estate, the property market regulation policy will also have a certain impact on doors and Windows and other home furnishing industries, but the purchase restriction is not completely equivalent to restricting the development of the door and window market. In such a realistic background, three or four tier cities or doors and Windows enterprises will become the direction of the layout.

In such a realistic background, three or four tier cities or doors and Windows enterprises will become the direction of the layout. Many provinces and cities in China introduced new policies to limit and upgrade real estate purchases First-tier cities: on March 17, Beijing introduced new policies, requirements "household name in this city has a set of housing, and no housing but in this city have the record or housing accumulation fund loans of the commercial housing loans, the purchase of the ordinary from the housing deposit not less than 60%, the purchase of ordinary from the housing deposit not less than 80%". On the night of the 17th, Guangzhou also introduced new control policies. The threshold for non-resident residents to pay social security or personal income tax will be extended from three consecutive years to five years. Adults who are single or divorced can only buy one set, pointing to a loophole in "fake divorces". 2. First-tier cities around: with Beijing as the center, since March, there have been four cities such as Zhuozhou in Hebei, Laishui County in Baoding, Chongli District in Zhangjiakou, and Shijiazhuang, etc., which have successively introduced purchase restriction policies. Jiashan County in Zhejiang Province, which surrounds Shanghai, restricted the purchase of new and second-hand houses, explicitly suspending the sale of new commercial houses to non-registered residents who own one or more houses in Jiashan County. 3. Hot cities: Nanjing, known as the "four tigers" in the property market, has made it clear that since March 16, registered households in Nanjing are fully restricted to buy a third house, while non-registered residents are extended to Gaochun, Lishui and Liuhe districts. This is Nanjing since last August, September, October after a series of tightening property policy, once again increased regulation. Zhengzhou, which has issued the property market control twice, is clear, where the supplementary payment and the supplementary payment date in March 17 after the social security certificate, income tax payment voucher is no longer as a valid proof of purchase, February "supplementary payment count" provisions to be amended. 4. Third-tier and fourth-tier cities: Seeking progress while maintaining stability is the general keynote of current work. The reporter sorted out the relevant regulation policies and found that in the face of the demand spillover brought by the purchase restrictions, some third-tier and fourth-tier cities reflected the characteristics of "stability" between the treatment of "live" and "fire". For example, Shijiazhuang and Ganzhou did not implement the whole area purchase restriction in the regulation, but chose to push forward steadily in the central urban areas. There are certain limits on the number of years of paying social security or individual income tax for non-registered residents of the city, and the requirements on the duration of payment are not high. Property market control doors and Windows enterprises can focus on third - and fourth-tier cities For the doors and Windows industry, downstream for the domestic purchase of commercial housing and stock housing renovation of urban residents, as well as the launch of refined decoration of commercial housing real estate enterprises will still form a certain consumer market. "Purchase restrictions in some third-tier and fourth-tier cities indicate that they have entered a dual-track parallel mode of 'destocking' and 'housing price control', but destocking is still the core task of third-tier and fourth-tier cities, and purchase restrictions are mainly aimed at local areas." Visible, doors and Windows enterprises want to develop, sink the channel to three or four tier cities, it will be a wise choice. In fact, there is a higher correlation between the delivery time

Cleaning the box inside the oil stain, dust detection automatic induction door accessories damage, detection of automatic door support deviation and small screw stable condition; Test the tightness of the drive belt; Test the output of the controller to the motor, the length of the opening and closing doors, the speed, the braking system and other conditions; Check whether the basic parameters of working voltage are normal value; Repair and replace damaged parts. Owners also need to pay attention to the timely maintenance and maintenance of automatic doors, automatic doors because of the impact of installation quality and operating environment, the operation will inevitably appear. If lack of maintenance for a long time, cause the automatic door has the security hidden danger and little situation do not properly handle, will be changed from a small to large, finally may cause the dysfunctional of automatic doors, wu kuang in addition automatic induction door company after construction of the project requirements as far as possible put a sign at the door in the operation, party a to avoid bumps into, cause accident harm.

Different materials: Non-professional medical door often use common layer board wood veneer, sandwich board, wood board and other materials, dedicated professional hospital door enterprises of medical door produced by using unified procurement of raw materials, all materials must meet the requirements of the use of the public hospital, must have the abrasion scrape resistance, fire prevention antibacterial, green environmental protection, acid-proof alkaline etc; Different design: generally speaking, the most can reflect the technical content of the hospital door is the design of its style, the hospital door function design must meet the requirements of the hospital, to avoid the phenomenon of the new hospital and the old door; Non-professional medical doors often lack function, can not meet the requirements of the hospital for product protection function, and non-professional medical doors have no standards, the production of product details is not in place, resulting in unstable product quality; Process is different: non-professional medical doors are usually processed in the field, the operator of the hospital door production of various requirements do not understand deep, rough quality, large error, difficult shape can not be manufactured, can not reach the appearance of the hospital needs. Quality is not easy to guarantee, professional hospital special door production enterprises have strict specifications for each step of the production process to import equipment fine processing, to ensure that the quality of their products meet the requirements of the hospital. Service quality is different: meticulous, thoughtful, comprehensive service is an important condition to ensure the quality of the hospital special door. Ordinary decoration team because there is no special hospital door production and installation of professional training, at the same time on the production process, the use of materials and so on do not understand, the production of hospital door products without quality assurance, and once the problem is difficult to maintain, and no after-sales service. The special door service of SIG hospital not only includes pre-sale door-to-door guidance measurement design, sales of door-to-door installation guidance, but also includes after-sales service, such as the establishment of user files, timely return visit, timely treatment of problems and so on. Know the difference between medical doors and non-medical doors. So what are the requirements of the medical door? Special requirements for functions: 1. Standby power supply connection interface must be available. 2, there must be a delay closing the door function and two induction function. 3, must have the function interface to start the air shower equipment. 4. Non-contact proximity sensors must be set, such as non-touch manual sensors or foot sensors. 5. Enhance the anti-clip function to improve safety, and the door body must be set up with kill resistance bounce back function. Door sealing requirements: 1. The voltage range applicable to the electric control part should be wide. 2. The electric control part must comply with the relevant national electromagnetic compatibility standards to prevent interference to medical equipment. 3, the motor reducer should be special, minimize the noise to meet the requirements of clean room noise. 4, the door body, the outer surface of stainless steel plate, electrolytic steel plate, color steel plate, etc., stainless steel plate is the best, but the cost is higher. The middle sandwich is made of foaming process or honeycomb structure for the door body with radiation protection requirements. The middle sandwich should be sandwiched with lead plate of certain thickness. In addition, metope seam should have seal Mosaic.
