Insulation strips play a very important role in broken bridge aluminum doors and windows. Because of the broken bridge aluminum insulation strips, this type of insulation broken bridge profile is called broken bridge aluminum doors and windows. Today, we will talk about broken bridge aluminum insulation strips. Precautions for use.

(The picture comes from the Internet)

1. Profile manufacturers establish a reasonable inventory

Water absorption is an inherent characteristic of nylon 66 insulation strips, so profile manufacturers should wear the strips as soon as possible after storage. Excessive moisture content will affect the efficiency of the strips or cause foaming when the profile is sprayed back. It is recommended to store the insulation strips The best temperature is 20℃~30℃, humidity ≤55%. As nylon 66 is brittle when the weather is cold and dry, it is recommended to properly open the outer packaging of the product 3 days before the strip is worn. The product can absorb a certain amount of water, reduce brittleness, and improve toughness.

2. Choose reasonable and effective test items

Since there are more than a dozen inspection items for national and industrial standards, and some items require 1000 hours or more professional inspection equipment to test, it is for the profile manufacturers to selectively test important items without significantly increasing the cost. necessary. The following briefly introduces a few test items that I think are more important.

①The product dimensional accuracy of the heat-insulating strip-this project can reflect the stability of the heat-insulating strip extrusion production process and materials to a certain extent. The high dimensional accuracy can improve the efficiency of the strip and increase the yield of the profile.

②Water absorption and transverse tensile strength of heat insulation strips-to a certain extent, it can reflect the advantages and disadvantages of the composite material formula used in heat insulation strips. If the composite materials used in the production of heat insulation strips are modified by special formulas and processes, then it can be The water absorption rate of the heat insulation strip is reduced, and the mechanical properties after water absorption remain relatively high. (The water resistance test can be boiled for 4 hours instead of soaking in water for 1000 hours).

③The transverse tensile strength of the insulation strip after drying-can generally reflect the quality of the insulation strip material and the stability of the production process.

④The high-temperature transverse tensile strength of the heat-insulating strip-can reflect the temperature resistance of the heat-insulating strip material and the stability in harsh environments, and can indirectly reflect the quality of the raw materials. Inferior raw materials have poor high-temperature performance due to more impurities (such as PE, PP, PVC, ABS and other polymer materials with poor heat resistance and low strength).

For consumers, it is the best choice to choose broken bridge aluminum insulation strips with PA66 nylon strips. Brands of broken bridge aluminum will be equipped with PA66 nylon strips, while counterfeit or miscellaneous brand broken bridge aluminum use PVC. Generally, broken bridge aluminum There will be electronic code marking PA66 nylon strips on the heat insulation strips, and the smooth surface of the heat insulation strips are PVC.

I believe that consumers have the answer in their hearts. Now the market’s mixed PVC products are sold as PA66. The real PA66GF25 is produced by Tianjin Ruifeng Rubber and Plastic Products Co., Ltd. which specializes in PA66GF25 insulation strips and has 40 nylon insulation strip production lines with an annual output. PA66GF25 insulation strip is 150 million meters, friends, since you have chosen broken aluminum doors and windows, don’t choose cheap insulation strips. Choose inferior insulation strips, which not only does not have air-tightness, water-tightness, and wind resistance. Pressure performance and thermal insulation performance.
