Epoxy resin potting ab adhesive ratio and use method, First, the proportion of epoxy resin ab adhesive formula
(1) Use dry cotton cloth or sandpaper to remove dust, oil, rust, etc., and then wipe with acetone or trichloroethylene and other cleaning agents to clean the surface.
(2) Unscrew the front cover and stir well agent B of the weight ratio of agent A + according to the above instructions (A:B=2:1); In order to ensure the effect of use, it can also be used after vacuuming.
(3) Note that it must be used up within the operating time, otherwise it will solidified, resulting in a waste of material, and the strength can be obtained after 24 hours.
(4) After coating: 2~6 hours curing at normal temperature 40 degrees ~50 degrees 1~3 hours curing; Apply glue 24 hours after use; Better stickiness after ten days. In cold and humid days, it is better to bond at room temperature of 15 to 25 degrees.
(5) Bonding face: When hanging upside down, use self-adhesive paper after gluing. Or position with 502 glue. Epoxy resin AB adhesive is a two-component high temperature resistant adhesive based on epoxy resin, mainly suitable for high temperature resistant metal, ceramics and other bonding. Its operating temperature is -50 ~ +180℃, and can reach +250℃ for a short time.
Epoxy resin potting ab adhesive ratio and use method
Second, the use of epoxy resin potting ab adhesive
a: AB glue manual mixing, gluing method
AB adhesive In the required ratio, the resin and the curing agent according to the standard weight ratio, in the container or operating table until they form a uniform mixture, the mixed material is applied to the pre-treated dry clean bonded surface. Use a stirring tool, plastic stirring sheet or bamboo stick. It is often used for AB adhesive with long operation time or in trial or small batch production. Please control the amount of glue mixing each time, the reaction will be heated after the mixture of A and B, the more glue, the shorter the curing time and the shorter the operation time, which is easy to cause waste.
b: Extrude AB glue with manual glue gun
Extrude AB glue with manual glue gun, install AB glue in different proportions of the mixed tube package on the glue beater, mix AB components evenly with the glue mixing nozzle, and apply the mixed glue directly on the surface to be bonded by manual extrusion. Suitable for continuous gluing, can effectively extend the operation time and control the amount of gluing, the disadvantage is that if the glue is stopped for a period of time, the mixing nozzle will be blocked, need to be replaced, and will waste part of the glue. Mainly used for bonding epoxy 50ml mixed tube packaging, the current available ratio is: 1:1/2:1/4:1/10:1
c: Hand-held pneumatic dispensing machine for AB glue
Hold the pneumatic dispensing agent to make AB glue, install the AB glue packed in different proportions of the mixing tube in the customized two-component dispensing valve (or dispensing cylinder), mix the AB glue evenly with the mixing nozzle, and apply the mixed glue directly on the surface to be glued by pressing the air pressure. Pneumatic dispensing machine can be set timing, quantitative glue, operability is better than manual glue gun glue, workers easy to operate, labor saving, low equipment cost. It can be mainly applied to 50ml mixed tube packaging, and the current available ratio is: 1:1/2:1/4:1/10:1
d: Intelligent automatic AB glue dispenser
Automatic AB glue dispensing machine, compared with the ordinary dispensing machine equipment, the same pressure control glue is pressed out by the cylinder, and the valve controls the size of the glue. The difference is that there are two sets of control systems, respectively control a glue and b glue. Intelligent operation, dispensing error, fast speed, suitable for complex dispensing. Can be controlled through the program dispensing amount, dispensing stroke, etc., there is a good consistency, high precision requirements, heterosexual materials, flow operations, production efficiency is a good choice. Can be used for different proportions of AB glue.
