Jinhua production how pressure sensitive adhesive jinhua production pressure sensitive adhesive thermal reaction 2 h 75 ℃, and then reaction and add the rest of the monomer and initiator, control 4 -
5 hours add up, and then heat up to 90 -
91 ℃, the heat preservation cooling below 50 ℃, half an hour with ammonia water pH adjustment to 6 -
5, stop stirring, discharging copolymerization emulsion.
If after drying glue have wiredrawing phenomenon of joint, then glue not dry, may be not enough temperature, drying time is too short, and the curing agent and too little or stirring evenly enough.
Jinhua production pressure sensitive adhesive how seven, pur moisture reactive polyurethane hot melt adhesive machine general in the maintenance of machinery safety precautions: poly cool from the binary acid and glycol, polyethylene phthalein amine from dibasic acid and diamine.
Attending the surplus glue, glue bowl don't fall back to the packing barrels, so as to avoid pollution of the glue glue in the bucket.
Water-based glue as long as the general besmear brushs a glue, if material is porous structure, can be two thin rubber, each must be dried before the second times adhesive, glue not dry property of stalemate, does to glue instead.
Jinhua how production pressure sensitive adhesive and then cooled to stir 60 ℃, adding 0.
10 and 1 gk12, after half an hour to make sufficient emulsification stir with a third mixed monomer and ammonium persulfate solution by one-third.
In the structure of polyurethane resin part introduce hydrophilic group, the emulsification.
Using a dedicated chip shoes repair adhesive glue, small area filling adhesive at room temperature from dry 5 minutes can use hand pressure, large area to the oven, the compressor pressing.
How about jinhua production pressure sensitive adhesive and VOC from auto interior materials, so the requirement of car interior trim stick or move hot melt glue VOC, requires no volatile substances, demand has no smell.
Using water-based adhesive
to be equipped with the following tools: how about jinhua production pressure sensitive adhesive with the increase of the main chain of carbon atoms, the melting point of polyethylene phthalein amine is reduced, and the melting point of vinegar is increased.
By bonding surface treatment: hot melt adhesive for bonding material surface treatment no other adhesive is so strict, but be dust on the surface of the adhesive material, oil should also do the appropriate processing, their best to make the hot melt adhesive glue.
Pneumatic or electric mixer b.
Plastic glue container c.
Plastic plastic container.
Jinhua production how pressure sensitive adhesive is used to make their own DIY design you have very different glue guns and decorate, DIY designer generally not long time use, recommend the use of glue guns for DIY friends together to design good work first and then glue glue gun.
Prepare two test.
In unit mixer, constant pressure drop funnel, reflux condenser and the 250 ml of the thermometer three flask, add 2.
Ethylene alcohol and deionized water 90 g 5 g.
Below small make up is detailed to introduce the product sell like hot cakes on the exhibition.
Jinhua production pressure sensitive adhesive like 4, car interior industries: automobile, is the second largest industry is a big industry, annual production of 22 million cars by 2014 above, China is power from the car to the car power shift.
