In the e-commerce live broadcasting industry, we are a relatively advanced team. In the early stage of the outbreak of short video presentation last year, we have begun to try to do live broadcasting, but the beginning of anything is always accompanied by barbarism and disorder. Live broadcasting is also the same. After the rectification and standardization of the live broadcasting platform, we officially started our career of live broadcasting with goods.

Because this is the first cooperation, the trust relationship is not so deep. In addition, we understand that the customer is so cautious as a partner. After thinking about it, we came up with a solution. First write a contract for the customer, then place an order in our Ali store, and choose the installment payment method to ensure that the goods and payment for goods are under the control of both parties. Before delivery, take packing pictures and logistics list. The customer confirms that there is no problem and pays the balance. This scheme has been recognized by customers, and the trust problem has to be properly solved. We often say that we should be careful to sail for ten thousand years. Especially at the end of the year, we should be vigilant and not relax. We should not blindly believe the information that has not been verified and stay sober to prevent being deceived.

Automobile sealing strip is one of the important parts of automobile. They are widely used in doors, windows, bodies, seats, skylights, recommended chassis and luggage compartment, and have other waterproof and sealing effects. In daily driving, remind everyone not to ignore the maintenance of sealing strip.

The differences between PU foam sealing strip and traditional sealing strip are as follows;Advanced thermoplastic rubber or nitrile rubber is used in combination with chlorosulfonated polyethylene;

Summer is a rainy season. My car is hungry and cold all year round. If the automobile sealing strip and sunroof rubber sealing strip are exposed to the sun for many years, they are prone to aging and cracking, and the sealing performance will be greatly reduced. It will not only affect the interior environment and sound insulation effect, but also cause water leakage in serious cases.

The quality of silica gel raw materials will make it difficult to remove the edges of silica gel products. The toughness and tear strength of silica gel raw materials with poor quality are obviously insufficient. It must be difficult to remove the edges in the process of edge removal. 2、 In the forming process, if the product is formed thicker, the burr is actually thicker. The increase of thickness must also lead to the difficulty of edge removal.

The sound insulation of the door is very important, because it is connected with the outside, which is the weak link of sound insulation. The sound insulation of the door mainly depends on the thickness of the door panel and the sealing degree between the window sash and the frame. When we live in high-rise buildings, we will find that the key to why electric heating and air conditioning do not work is that the thermal insulation effect of doors and windows is too poor. The reason for this is that the door and window tightness is too low. Hot air or cold air can enter directly from the gap, and the cold air or hot air in the room overflows seriously. Even if good equipment is installed, the root cause can not be solved. Most of the energy still slipped away. Doors and windows with low tightness not only save energy and reduce consumption, but also have poor sound insulation effect. The sound insulation of holes and gaps is also related to the wavelength or frequency of the incident sound wave, because the higher the frequency, the shorter the wavelength. Therefore, even if the gap is very small, it will be unfavorable to the sound insulation of high-frequency sound.

Door and window sealing strip is a kind of sealing piece mainly suitable for plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decorative doors and windows. Plastic steel door and window sealing strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR and SEBS) and silica gel. The sealing strips of doors and windows are divided into glass sealing strips (rubber sealing strips), door leaf sealing strips and wool sealing strips. Glass sealing strip is used for sealing between glass, door leaf and door frame.

At present, steel, aluminum alloy and plastic doors and windows are generally used to install the seal between glass and door and window frame and leaf. Plastic seals are generally used to install the seal between glass and door and window frame and leaf. Rubber and plastic sealing strips are usually made of modified PVC materials.

Wind noise is caused by the gap between the air and the vehicle during driving, the sound generated by angular friction, the vehicle door, front engine cover and trunk, and the wind noise with reduced gap. Article car sealing after the car has been tested by rain all summer, timely check whether the car owner's sealing strip has hardened, deteriorated and damaged, and whether it has been replaced in time, The following suggestions should be paid attention to when replacing the automobile sealing strip!
