Ningde professional sealing rubber prices ningde professional sealing glue hot melt adhesive
machine in appearance, in addition to the need to add the corresponding pigment when used in color printing paper, the general quality of rubber or film surface is smooth, shiny, no rough milky white or pale yellow solid impurities.
2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified.
Hot melt adhesive observe whether there is a powdery material after melting, if there is a powdery material specification packing, adhesive performance is poor.
With heat resistance performance, good quality hot melt adhesive, you can put the hot melt adhesive in zero or more than 40 degrees respectively environment for testing, if there are brittle, soft gelatin said quality is bad now.
1 - after coating
Organic silicon and other resin pressure-sensitive adhesive composed of organic silicone resin and organic silicone rubber pressure-sensitive adhesive, has excellent high temperature resistance and aging resistance, is a kind of important special pressure sensitive adhesive, its main purpose is to make all kinds of high-grade pressure-sensitive adhesive products.
In general: industrial glue has high strength, large temperature range of applicable temperature, viscosity range, low price, easy production, and other characteristics.
At present good quality hot melt adhesive can be used in the field of industrial manufacturing, heat resistance performance and flame retardant performance is guaranteed, the current can reach the quality requirements must be big brand products, such as ke, Moore, focus on the study of the hot melt adhesive, provide customized hot melt adhesive application solutions, wide range of USES, can be applied to new energy, military industry, aviation, shipbuilding, electronics, automobiles, instrument, power supply, high iron, and other areas of the industry.
5, pur hot melt adhesive machine in the transport and handling process, must always keep pur hot melt adhesive machine is vertical, if inclined handling or transportation will damage the positioning precision of pur hot melt glue machine, may also be damaged pur hot melt adhesive machine.
Because the effects of solvent is solvent resin or additives, additives, etc. , given to liquidity make the ink, glue easily distracted.
Although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive.
Ningde professional sealing glue adhesive for building industry space price space development and utilization of more and more, all kinds of vehicle such as space adhesive is widely used in spacecraft, the space shuttle, due to its a bad thing, have special requirements on the performance of the adhesive.
Heat preservation 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.
Hot melt adhesive is a kind of plasticity strong adhesive, and the adhesive can be adhesive, and a variety of substances can changes with temperature changes in the nature, after curing adhesion, adhesive strength is big, so many industries can use this kind of adhesive.
If the adhesive is for ordinary families, the quality is not important.
If it is used in the industrial field, requires attention to quality, so how to determine the quality of the hot-melt adhesive?
Commonly used grinding wheel is mainly with phenolic resin adhesive bonding.
Ningde professional sealing glue price 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.
