Aluminum foil tape more and more love to people's attention, is a very promising industry
Metal tape is generally made of aluminum foil tape and copper foil tape, copper foil tape is mainly used for difficult to fix the insulation of the insulator, less use within the scope of aviation. Aluminum foil gum is mainly used for collective external repair, can also be used for heating steam pipe package, can play a role in preventing the temperature out of the loss. Aluminum foil tape has a wide range of applications, easy to use, high economic efficiency, rapid development and many other features, with the economic development and technological progress, it will become more and more people pay attention to become a very promising industry.
The foil roll should have a high hardness that requires a sensitive gage with an accuracy of ± 0.5 microns. And to maintain the roll surface gloss, reduce surface wear and accidental damage. Roller curvature must be accurate, because the aluminum foil rolling, the roll of elastic deformation, that is, deflection, need to use a certain degree of convex compensation. In the commonly used aluminum foil thickness gauge, the eddy current thickness gauge is simple in structure and easy to maintain. However, due to the fluctuation of voltage fluctuation and temperature, the zero point is easy to drift. Therefore, there should be voltage regulator and temperature compensation device, and should always measure the thickness of aluminum foil To calibrate the zero point of the eddy current gage.
From the characteristics of aluminum foil and its rolling characteristics can be seen, the impact of aluminum foil quality factors, if the workers do not have long-term training, is not proficient in aluminum foil rolling technology. Aluminum foil producers should know: the nature of aluminum, use; equipment and equipment procedures and the main technical data; the nature of the process of lubricants, the role of requirements; billet and finished products such as the standard requirements; waste generation and elimination methods; The nature and requirements of the tool; aluminum foil heat treatment basic knowledge; production, economics, technology and quality management knowledge.
Aluminum foil tape with high-quality pressure-sensitive adhesive, good viscosity, strong adhesion, anti-aging effect! Insulation performance greatly improved, the specifications have a variety of width and length. Aluminum foil tape with all the aluminum foil composite material paste paste, insulation nail puncture at the seal and damage repair. Is the refrigerator, freezer production plant of the main raw and auxiliary materials, but also insulation materials distribution sector must purchase raw materials. This product is widely used in refrigerators, air withered, cars, petrochemical, bridges, hotels, electronics and other industries.
Reduce the toxicity, to the environment-friendly development; improve performance, to meet the different bonding objects, production process requirements; through different ways to modify, reduce costs, must be wood processing tape development and application of the overall development trend. Melamine can react with the water-absorbent groups in the urea-formaldehyde resin. At the same time, the basicity of melamine can neutralize the acid in the adhesive layer to prevent and reduce the hydrolysis rate and thermal degradation of the resin to a certain extent. Therefore, Melamine modified by urea-formaldehyde resin, while reducing the release of free formaldehyde, but also can improve the urea-formaldehyde resin water resistance, dimensional stability and wear resistance and other properties.
