Revolving door seal is a type of seal mainly used for decorative doors and windows of buildings such as plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows. Plastic steel Revolving door seal on the market is generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR, SEBS), silica gel and other materials.

Revolving door seal is divided into three categories: glass sealing strips (adhesive strips), Revolving door seal and tops. Glass sealing strips are used for sealing between glass and fan and frame. Revolving door seal is mainly used for sealing between door panels and door frames. Tops are mainly Used for sealing between frame and fan. In the production and installation of plastic steel doors and windows, broken bridge aluminum doors and windows, and wooden doors, Revolving door seal is an indispensable accessory.

The glass is not installed in the center, the gap between the glass and the window frame is uneven, the rubber sealing strip is not close to the glass and the window frame, and the installation is uneven. Knock the glass with your hand, there is a loose sound. The reasons for this situation:

1. The sundries in the notch are not removed in time when the glass is installed, so that the glass is not aligned with the notch.

2. The gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass and the glass groove, protruding from the glass notch, and the sealing strip can be easily pulled off by hand.

3. The rubber strip is not broken at the corners, and glue is not injected.

The corrective measures are:

1. Before installing the glass, carefully remove the debris in the notch, such as mortar, brick chips, wood blocks, etc., carefully align the glass when placing it, ensure that the gap on both sides is even, and correct and fix it in time to prevent collision, displacement, and deviation Center of notch.

2. The rubber sealing strip cannot be pulled too tightly, and the blanking length is 20-30mm longer than the assembly length. The mounting should be in place when installing, the surface should be straight, and it should be in close contact with the glass and the glass notch so that the force around the glass is even. At the corners, the rubber strips should be cut off with a bevel, and glue should be injected at the break to be firmly bonded.

3. When sealing the glass with sealant, you should squeeze the glass with a rubber strip or a rubber block to leave a gap for the glue. The depth of the glue should not be less than 5mm. Before the glue is cured, the glass should be kept from vibration.

Revolving door seal plays an important role in waterproofing, sealing and energy saving in plastic steel doors and windows, broken bridge aluminum doors and windows, and wooden doors and windows. It is soundproof, dustproof, antifreeze and warm. It must have strong tensile strength, good elasticity, and better temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structure size of the rubber strip must match the plastic steel door and window profile. Sealing strips are generally used for casement doors and windows, hanging windows, and folding doors and windows. The main functions are dust-proof, insect-proof, waterproof, soundproof, and sealing.

The installation location of Revolving door seal is generally on the door, around the frame fan or on the sealing bridge (wind block) to enhance the seal between the frame and the fan. Top specification is an important factor affecting the performance of sliding doors and watertightness, as well as an important factor affecting door opening and closing force. Oversized tops or high vertical hairs will not only be difficult to assemble, but also increase the resistance of the door, especially the initial resistance when opening and the final resistance when closing. If the specifications are too small, or the height of the vertical tops is not enough, it is easy to fall out of the groove, which greatly reduces the sealing performance of doors and windows.

Revolving door seal has silicified and non-silicified tops. The silicified tops have better effect in use. The tops with qualified quality have a straight surface, and the bottom plate and vertical bristles are smooth, without bending, and there are no pits on the bottom plate, which conform to 0.2mm. Regulations.
