Spring Festival is approaching, in the cold winter, the owners will note whether directly immersed in cold car, occasionally accompanied by wind noise, I feel like the door is not closed tightly same. So this time we had to check under the seal. Seal can improve air tightness and prevent intrusion into the compartment within the storm. Once the seal breakage aging, will cause the car leaks, increasing the car's driving wind noise, leaks and very easy to make the body rust. It is not difficult to see on the car, the seal is an important part, and usually must be checked regularly maintained. There are now a number of professional vehicles sealed shop for different models tailored to exactly match the original car slope and curvature of the curve, to ensure continuity between the various components of the body to avoid flow separation to produce binding sites, easily resolved periodic tail flow, can reduce wind noise at high speeds, while enhancing the original car's airtight and dust capacity.

Sealing several key positions

        Before installing the glass doors of the vehicle should seriously clear the debris inside the slot, such as mortar, brick dust, wood, etc., should be placed carefully on the glass, ensuring that both sides of the gap is uniform, and timely than the regular fixed to prevent collisions shift deviation notch center. Rubber seal can not pull too tight, cutting length longer than the length of the assembly 20-30mm. Should be installed in place mosaic, flat surface, and glass notch in close contact, so that the glass surrounding the force evenly. In the corner of the rubber strip should be beveled off and disconnect the injection of glue at the firm. When caulking sealant fixed glass, you should use rubber or rubber blocks of glass and choked, leaving a gap plastic injection, plastic injection depth should not be less than 5mm, before the adhesive curing, the glass should be kept free from vibration.

        Vehicle frontier seal trailing edge and side edge seals: support from the hood, on the hood front, rear and along the side edges of the anastomotic site and the body of paste, can the gap between the hood and the body for effective sealing, vehicle on the way, can accelerate the air from the intake gate through improved thermal performance. At the same time, you can reduce the hood and the front part, the friction between the left and right front fender, reducing noise and friction caused by the bump. If the gap is large, you can paste layers.

        Four doors through the gap between the seal and the vehicle body, the vehicle can effectively improve the sealing performance, reducing wind noise. Improve sealing performance can also prevent dust, rain water into the cockpit, to improve the efficiency of air conditioning and refrigeration. Carefully glue coated on the inside of the door, will cut a good seal is also coated with glue on one side, then the door seal affixed along the inside circle.

        Right around skylights paste, can effectively improve sealing, dust and water; for air conditioning and refrigeration pipes wrapped, can improve the cooling efficiency. Between the door trim panels and the gap between the dashboard, storage boxes and other car interior parts, assemblies and precision due to other reasons, there is often friction, vehicle process will cause resonance at different speeds produce an annoying noise, which is generally difficult to find. Actually know the reason, as long as the seal these gaps to fill, you can paste.

        When repairing a door seal flange, the flange should be noted that repair damaged seal, to accurately restore the original shape of the flange. After repairing the door to be tightness check, check method is: put a piece of cardboard in a sealed position, close the door, and then pull the paper, based on the size of the rally to determine whether a good seal. If the force required to pull the paper described excessive tight seal, which will affect the normal closed door, and also the seal due to deformation of an excessive surface faster loss of sealing performance; if the force required to pull the paper through the small, indicating poor seal the door will always be the wind does not rain phenomenon. When replacing the doors must pay attention to the new inner and outer door panels painted at the hem flange bite glue and put some holes left by the time stamping of the base tape blocked.

Note that when the seal repair several places

        In the rear window glass damage, changing the original window glass with the same curvature of the glass, at the same time to check the glass guides and seals for damage. Because of the window after repair often reply less than its original shape, and therefore, when in addition to the guarantee can easily pull or lift the window glass, but also pay attention to the window glass in the windows closed after four weeks of tightness. If the glass with glass notch gap uneven, rubber and glass tank is bad, protruding glass notch, hands can easily pull off the seal.

        When changing the roof, the roof should be applied at the periphery lamination layer of conductive sealant, well then be welded seams in the water tank and fold over the painted plastic, which will not only contribute to the body of the seal, but also prevent the body due to the flange welds produced water early rust.

        When replacing the entire body, except for the above projects should be completed, but also on the lap portion of the weld joints are coated with a layer of sealant layer thickness should be about 1mm, and may not have a virtual sticky glue , bubbles and other defects; at the hem hem should be coated with special glue; in the entire floor surface should be coated with a lower surface and the front cover elastomeric coating and anti-corrosion coating of 3mm-4mm; these measures will not only greatly enhance the whole car body sealing and slow down the corrosion rate, but also can greatly improve the ride comfort.

Routine maintenance needs in place

        First, check for large cracks seal, without fracture. If the seal or breaking the larger cracks can be repaired using an adhesive. Particularly the use of special adhesive seal, it is easy to put up a good large cracks article. Of course, if the seal serious injury, or a greater degree of aging, it is best to replace the new seal easy. Replacing the seal is not difficult, but in order to do a better job, better ask professionals.

        Routine maintenance work seals, including the following. The first is the use of the car wash detergent, after cleaning, coated with a highly permeable protecting agent, so as to prevent aging of the sealing strip. In addition, it is easy to fill up the gap between the seal dust, causing corrosion. For this reason, you should use a brush to remove dust and other clean.

        Seal windows and doors is an important part of effective measures to ensure that it is airtight doors, watertight, noise, etc., but it is also a reliable guarantee of glass in windows and doors after by external security presence. Since the seal affected by climate and sunlight, will produce shrinkage, aging, deformation, and therefore, the sealing strip is not allowed in a stretched state operation, should be kept its free state. In order to firmly stuck to the glass, the installation process will often pull too tight seal, can not guarantee a free   state, so that in the tensile deformation state. Practice has proved that, due to the sealing strip is installed on the tensile deformation state, has emerged seal off, pull off, cracks and other phenomena. For this reason, during installation, seal doors and windows assembly length than the side a little more, at the corner of the slope off, stick firmly with adhesive, allow sufficient margin expansion.
