How to use electrical and electronic adhesives, electrical and electronic adhesives on the human body is harmful?

Electrical and electronic adhesives in accordance with the correct use of low harm to the human body, so we need to pay attention to the correct and safe use, to avoid prolonged exposure. The correct use of electrical and electronic adhesives is: before use, you need to clean the surface of the bonded object, and then the adhesive will be applied to the bonded object, and then the two objects will be pressed together, wait for a period of time can be completed after bonding.

　　Electrical and electronic adhesive introduction
　　1、Epoxy resin

　　Epoxy resin is a commonly used electrical and electronic adhesive. It has strong adhesion and high temperature resistance, and can be used to connect electronic components, repair circuit boards, bonding metals and plastics. Epoxy resin can also prevent moisture and shock, to ensure the long-term stable operation of electronic equipment.

　　2、UV curing adhesive

　　UV curing adhesive is a fast curing adhesive, can be completed in a short period of time bonding process. It is cured by ultraviolet irradiation, with strong adhesion and high transparency.UV curing adhesive is often used to bond fragile electronic components, glass panels, LCD screens, etc., which can provide reliable bonding effect.

　　3, hot melt adhesive

　　Hot melt adhesive is a kind of adhesive that melts by heating and becomes solid later. It is easy to operate, strong adhesion, suitable for a variety of electronic equipment repair and assembly. Hot melt adhesive also has thermal insulation and waterproof properties, can provide good protection.

　　The epoxy resin, UV curing adhesive and hot melt adhesive introduced above are all common electronic and electrical adhesives. They each have their own characteristics and can be selected according to specific project needs. Choosing the right adhesive can ensure that your electrical and electronic equipment stays in good condition and lasts longer!

　　Are electrical and electronic adhesives harmful?
　　For most electrical and electronic adhesives, the hazards to the human body are relatively low when used in accordance with proper usage and precautions.

　　Harmful substances in electrical and electronic adhesives, such as toxic and harmful solvents, additives, volatile organic compounds can be harmful to human health. Therefore, you need to pay attention to safety when using them and avoid prolonged exposure.

　　How to use electrical and electronic adhesives
　　The use of electronic and electrical adhesives varies with different adhesives. Generally speaking, before use, you need to clean the surface of the bonded object, and then apply the adhesive to the bonded object, and then press the two objects together and wait for a period of time to complete the bonding.

　　Detailed steps are as follows:

　　1、Preparation

　　Before using the adhesive, make sure the working area is clean to avoid impurities attached. At the same time, prepare the required utensils, such as brushes, syringes or droppers, in order to apply the adhesive finely.

　　2. Surface Preparation

　　Before applying adhesive, make sure the surface to be bonded is dry, clean and smooth. If there are traces of grease, dust or old adhesive on the surface, wipe with a clean cloth or alcohol to remove impurities.

　　3、Coating adhesive

　　According to the specific type of adhesive, use a brush, syringe or dropper to apply the adhesive evenly on the part to be glued. Make sure to apply the right amount and thickness to avoid over or under application.

　　4. Curing and pressing

　　Depending on the type of adhesive and requirements, wait for the adhesive to cure. During this process, use jigs or presses as needed to keep the bonded parts in close contact to ensure good adhesion.

　　5、Cleaning and storage

　　After completing the bonding, clean the tools and adhesive residue in a timely manner to prevent curing formation. Storage of the remaining adhesive should be in accordance with the requirements of the product instructions to avoid excessive heat, exposure or excessive humidity.
