Domestic insulation strips-identification of insulation strips
Exterior. The nylon heat insulation strip is black matte color, and the whole is smooth and flat, no shrinkage, no looseness, no scratches and mold extrusion marks, and you can see a special luster of minerals (glass fiber distribution) when you look closely at the light. The heat insulation strip head There is no parting line mark on the end surface; other imported or domestic nylon heat insulation strips are gray-black or dark black, without any trademark signs, and the strips are relatively rough. The mold extrusion marks and the parting line marks on the head end face are obviously visible, and there is shrinkage. The holes are loose; while the PVC heat insulation strip is bright black, without any trademark logo, the strip body is rough, the mold extrusion traces are obviously visible, there are a lot of shrinkage holes and loose, and the head size is asymmetrical and irregular.

Ordinary ignition experiment. Nylon heat insulation strips are not easy to ignite and show a light yellow flame when burned. PVC heat insulation strips are flammable and show blue flames when burning, and release a large amount of pungent black smoke.

Break the experiment. Take the I type specification 625px sample for manual breaking experiment. When the Tylenol baotai nylon heat insulation strip is bent, it can feel good toughness and strength. It will not break when the two ends are folded, even if the fracture is slowly broken. Phenomenon; other imported or domestic nylon insulation strips are either obviously brittle, and multi-segmented cracking occurs when the two ends are bent to a certain distance (due to uneven glass fiber particles), or the toughness is obvious, and repeated bending many times ( Insufficient glass fiber content); PVC insulation strips are very soft, basically weak, and will not break after repeated bending.

Do you understand the system knowledge of heat insulation strips introduced above? With the development of society, all walks of life in society have increased their attention to the goal of environmental protection and energy conservation. Many advanced companies not only innovate and develop, but also pay more attention to resources. Recycling and energy saving make the use of products such as heat insulation strips that reduce useless losses more widely.
