Metal hose connector basic method of selecting adhesives

Adhesive has a special feature, the metal fittings are widely used. The world for different purposes than ten thousand kinds of adhesive above, the choice of adhesive, the need based on the following four tips to judge. (1) The dielectric properties of the different types of gas or injection of the adhesive force of dissolution medium is quite different, and even then angle during operation of a prime mainly air, water, oil, and acids. Hydraulic tube fittings  Use adhesive should be selected using the media-resistant plastic. (2) The adhesive strength of the adhesive strength and tensile strength, shear strength, torsional shear strength and peel strength lengths denote private detective adhesion member in a different direction of the force of the breaking strength. Select adhesives, should be based on the position of mechanical parts and force the situation with suitable choice misunderstanding strength adhesive. (3) heat resistance refers to fully cured layer can withstand temperature range, such as a temperature -60 º C-120 º C, that is, the stick and can be -60 º C to 120 º C range applies exceed this limit, the adhesive force decreased. (4) Curing time Curing time is hereinafter bonding adhesive at room  Hydraulic hose fittings  into a solid plastic housing gummy at the required time. Fixture is exposed adhesive layer is not due to weight loss pieces time required; whole solid layer is fully cured, and the highest strength and resistance to media stick Sharp function best time. Nylon cable ties on the slow Adhesive For shorten the curing time, the available heat blowing heated oven baking and other measures, but the heating temperature and time should be different types of plastic may be. The above points are Yong-yu adhesive metal hose fittings selecting the basic principles, and only correct choice adhesive in order to achieve the desired results, the use of recovered metal hose connector performance, thereby improving the utilization of metal pipe joints, increase economic efficiency.
