502胶水（502 glue）

502胶水（502 glue） 502胶水(502 glue) For small parts assembly, assembly, process fixation, crack repair, needle hole plugging and so on, can be applied to the permeation method to apply glue, which is to be fixed first, then the glue, by the hair fine effect suction the adhesive surface. The shape and material of the adhesive can be applied to any one side. If the shape and material are not at the same time, the adhesive is glued to the face of the face, or the smaller side, or the face that is slow to solidify, or difficult to penetrate. It is best not to immediately after coating composite, according to the size of air humidity, air buy 1 ~ 5 s, the glue in air exposure duration and the relationship between the bonding strength is great, when air buy more than 2 min, performance fell by more than 50%, the highest bonding strength within 3 s. The alignment of the position shall not be staggered, or the adhesive strength will be affected. Pressure to keep the adhesive close contact, the pressure time generally is 2s ~ 5min. Pieces of the adhesive curing speed related to temperature and humidity, bonding area of high temperature and humidity, curing speed, low polymer relative molecular mass, bonding strength decline, the most suitable temperature for 20 ~ 30 ?, relative humidity is 50% ~ 50%, no more than 70%, otherwise easy generation whitening. The maximum intensity is 24h. The removal of residues from such organic solvents as acetone, toluene or dimethylformamide can be removed and the following methods can be used: In acetone, nitromethane, DMF, or soak in 70 ?, 10% NaOH solution, can fall off naturally. Filled with alcohol lamp or hot mineral oil make workpiece heated to 150 ?, with a little force to open it. Because of the low impact strength of the rubber layer, the parts can be separated by striking. Note: The generic type is not ideal for porous material, and it needs to be modified thickened. When it is bonded to metal, it is mainly used for temporary emergency bonding. The adhesive should be tightly sealed and put in a dry and cool place. The article should avoid light, avoid heat and keep away from open fire. Glue liquid low toxicity, the nose and eye has certain stimulating, and unpleasant smells, therefore, glue place should be well ventilated, operation should wear protective glasses, adhesive solution one thousand splash into eye, rinse with plenty of water immediately, and into the grease eye ointment, do not rub your eyes, more can't use solvent washing eyes, should be timely medical treatment. If the skin is glued to the skin with adhesive, it can not be hard to tear hard, and it can be gently rubbed away with warm water or acetone solvent. Don't enter into the eyes. Don't let children contact. The liquid should avoid contact with water or alkaline substances, or it will cause polymerization and failure.

Use a banana water drop on the glue water stain, and use the old toothbrush to brush continuously, until the glue track becomes soft and removed, then rinse with water, brush and wash, and clean. Add water to the back of a garment that has a trace of glue, then apply some white vinegar to the traces of glue, and then wash it with cotton 2 remove 502 from the original place, melt the original 502, then rinse off with water quickly, very clever! 3. With insulation oil, the insulation oil in the transformer is on the table. 502 glue quickly becomes soft and can be rubbed out quickly. 3 c solution can be washed The 502 glue is a kind of resin glue, as long as the organic solvent of dissolved resin can be used, such as acetone. But inhaling acetone is poisonous, and the way to use it is to put the glue in the bottle. It's said to be frozen in the fridge, the glue will fall off, so you can try it first The small area is sticky with 502 glue, just soak in hot water can, if large area is touched 502 glue, daub on acetone, wait 5 ~ 10 minutes can be removed. Recommended acetone, gasoline, sesame oil and so on, the insulation oil in the transformer is in hand, 502 glue quickly become soft, finally rubbed out. 1 drop 502 in the original place to melt the original 502, then quickly rinse off with water, very clever! 2. Using insulating oil, the insulation oil in the transformer is on the table. 502 glue quickly becomes soft and can be rubbed out quickly. 3 c solution can be washed The 502 glue is a kind of resin glue, as long as the organic solvent of dissolved resin can be used, such as acetone.

Using insulating oil, the insulation oil in the transformer is on the table. 502 glue quickly becomes soft and can be rubbed out quickly. 3 c is clean with solution The 502 glue is a kind of resin glue, as long as the organic solvent of dissolved resin can be used, such as acetone. But inhaling acetone is poisonous, and the way to use it is to put the glue in the bottle.

But inhaling acetone is poisonous, and the way to use it is to put the glue in the bottle. It's said to be frozen in the fridge, the glue will fall off, so you can try it first The small area is stuck to 502 glue, just soak in hot water, If a large area is covered with 502 glue, apply acetone, about 5 ~ 10 minutes can be removed. Use banana water drops on glue water stain, and use old toothbrush to brush continuously, until the glue track becomes soft take off, then rinse and rinse, brush clean. Add water to the back of a garment that has a trace of glue, then apply some white vinegar to the traces of glue, and then wash it with cotton. Recommended acetone, gasoline, sesame oil and so on, the insulation oil in the transformer is in hand, 502 glue quickly become soft, finally rubbed out. 1. Removal of adhesive stains You can use acetone or banana drops on glue stains, brush repeatedly, and remove from fabric and then rinse with water. Not once, but can be washed repeatedly several times, can be washed. Do not use this method to avoid damaging clothing fabrics. When the stain is dissolved, rub it with your hands until the stain is completely rubbed out. Then wipe it with warm cleaning fluid and then rinse with water. You can use acetone to dissolve the 502 glue. After wetting with acetone, scrub with a soft cloth, then rinse with a 2% ammonia solution and rinse with water. When the stain is dissolved, rub it with your hands until the stain is completely rubbed out. Then wipe it with warm cleaning fluid and then rinse with water.

Recommended acetone, gasoline, sesame oil and so on, the insulation oil in the transformer is in hand, 502 glue quickly become soft, finally rubbed out. He recommended acetone, gasoline, sesame oil, etc., and Mr. Sun's colleagues tried one by one. Finally, he poured some insulating oil into his hand 502 the glue quickly softened and finally rubbed out. 1 drop 502 in the original place and melt the original 502, then rinse off with water. 2. Use insulating oil, and the insulation oil in the transformer is on the clothes. 502 glue quickly becomes soft and can be rubbed out. 3 acetone solution 502 glue is a resin glue, which is used in solvents of dissolved resin, such as acetone (acetone is poisonous and USES the method). It is said to be put in freezer to freeze brittle glue also can fall, can try. Small area 502 glue, can be soaked in hot water, Large area 502 glue, but acetone, etc. can be erased after dissolving. 1, the removal of the glue stains The clothes are stained with the glue stain, can use acetone or banana water drops on the glue stain, want to use brush repeatedly brush repeatedly, wait for glue to become soft from the cloth to be taken off, and then wash with water. Not once, but can be washed repeatedly several times, can be washed. Do not use this method to avoid damaging clothing fabrics. Objective to investigate the characteristics and treatment of 502 gum strayed injury. Methods 502 glue for 23 cases (25 eyes strayed into the performance of the eye to eye damage and processing is analyzed. The results of 23 cases (25 eyes 502 glue go left eye adhesion on the corneal and conjunctival or become a foreign body in conjunctival sac. Due to the stimulation, adhesion and friction cause corneal and conjunctival shallow damage. The disposal of the unfavorable first wash with physiological saline, and need to drop 1% tetracaine eye drops to reduce the adhesion of 502 glue adhesion on the surface of the cornea, conjunctiva, easily be removed 502 glue. Conclusion 502 glue into eyes should drop 1% tetracaine eye drops lower the adhesive force, and can be easily removed adhesion on the surface of the cornea, conjunctiva, foreign body rubber (502).
