First look from the outside to see if there is any flaws, whether the tape is pasted, whether there is a hairline cut, whether it is smooth to look at the tape material(electrical insulation tape with many types, do not introduce the quality of the material evaluation, in most cases Still look at the use situation).

The failure types of pressure sensitive adhesive are mainly divided into three types: interface damage, rubber layer damage, and mixed damage. In general, the adhesion effect of the pressure sensitive adhesive depends on the interface adhesion strength and the cohesion strength of the adhesive itself.

What are the parameters that affect the die-cutting quality of the glassin type paper?

There's one thing the electrician industry needs: insulation tape, which we can also call insulation tape. It not only does that, but it also has a very good viscosity, so he is very popular in electrical insulation protection.

Nowadays, the steam tubes of ships use aluminum silicate plus asbestos to achieve thermal insulation, but due to leakage or cold and heat alternately produce condensed water and gather on the outer wall of the steam tube at the bottom; And the steam tube is subjected to high temperature and soluble salt for a long time, and the outer wall corrosion is very serious.

With the use of adhesive technology more and more widely, the aging problem of adhesive joints has received more and more attention. The reasons for aging adhesive joints can be divided into the following aspects: the impact of mechanical loading on joints, the impact of the natural environment on joints, and the transfer of adhesive components. Today, let's talk about how the natural environment contributes to the aging of bonding joints:

Notes for using adhesive.
