Xiangyang whole series of food-grade plastic agents xiangyang whole series of food-grade plastic agent hot melt adhesive
machine in appearance, in addition to 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.
Water-based glue to use plastic containers, do not use metal containers, otherwise it will affect the glue of resistance to yellowing coefficient.
Xiangyang full range of food grade glue agent 5, pur hot melt adhesive machine in the transport and handling process, must always keep pur hot melt adhesive machine, vertical if tilted handling or transportation will damage the positioning precision of pur hot melt glue machine, may also be damaged pur hot melt adhesive machine.
Type hot melt adhesive with stable performance, high utilization rate of raw materials, production speed, high yield, 13, equipment cover an area of an area small, and the advantages of small investment of other major acrylic epoxy resin adhesive products silicone acrylic acid with acrylic acid, methyl acrylate, ethyl acrylate and acrylic acid
Ethyl caproic ester copolymer emulsion, such as for electrostatic flocking, flocking adhesive, its fast and feel good.
Water-based glue because volatilizes slower, must add 5% of waterborne curing agent, and mixing 5 -
8 minutes, mix evenly, add the curing agent of glue must be finished within 4 hours, do not use the next day.
Xiangyang whole series of food-grade plastic agents out of the plastic 6 according to the weight of the brackets than add hardener (
Today hardener added amount is accurate right amount, will affect the early stages of the water-based glue then force and heat resistance;
All landowners with pneumatic stirrer, set of mixing time, under the 300 ∽ 500 RPM speed, stirring for 10 minutes.
Search the public number: WPU -
88 China adhesive platform 8 water-borne pressure sensitive adhesive: stick on the tag is not enough, or early attachment is weak;
Vacuum suction plastic: positioning surface bubble, and the early strength is low;
Paper packaging glue: glue machine after become warped outlet, need to bale or weight.
Pu polyurethane including pressure sensitive adhesive and PUR water-borne pressure sensitive adhesive glue, hot melt pressure sensitive adhesive, is a kind of pressure sensitive adhesive, mainly composed of synthetic rubber and resin and rubber oil mixture heating molten state and then coated on cotton paper, cloth or plastic film, such as base material and made a new type of adhesive tape, on the advantages of low cost is its defects is affected by temperature is obvious adhesive.
In the 50 - water-based glue drying temperature
3-60 ℃, drying time
About 5 minutes.
Main equipment and instrument, but most of the existing reactive flame retardants are unable to greatly improve the flame retardancy of pressure sensitive adhesive, also need to add some additive flame retardants and two or more than two kinds of flame retardant association effect, can maintain the pressure sensitive adhesive pressure sensitive resistance and flame retardant balance at the same time, improve the flame retardancy.
Water-based glue cannot add oil curing agent, otherwise easy to cause death glue or glue agglomerate, cannot use.
Xiangyang full range of food grade glue agent measures to edit step 1.
Will be zero.
57 g of ammonium persulfate dissolved in 5 ml of distilled water, made from 5% ammonium persulfate solution.
If it be adhesive content itself to the color no special requirements, it is recommended to use yellow hot melt adhesive, generally speaking, yellow hot melt adhesive is better than white sticky.
To thin and uniform, water-based glue coating is too thick, after drying, can clearly see the underlying material, if see is the white layer and the brush glue is too thick.
Smell, especially is faulty, people would think is unsafe, so the food and drink beer manufacturer of hot melt adhesive were put forward such as no smell, no smell of glue lets the user feel safe, rest assured, the steadfast.
Choose can satisfy the requirement of early viscosity of emulsion compound with (
The low glass transition temperature of the emulsion can increase viscosity resin emulsion (
High glass transition temperature of polymer emulsion and plasticizer or low liquid viscosity resin emulsion point (
Heating or dispersion increases system mixing degree.
Xiangyang full range of food grade glue agent 4, clean up the pur hot melt adhesive machine heating platen, workers must wear special high temperature resistant protective clothing, with high temperature resistant gloves, do not make the skin contact with hot melt glue barrel, molten pur hot melt adhesive and hot plate and high temperature parts, to avoid.
3, food packaging industry: in recent years, food safety more and more get the attention of people, our life is also true that there are too many unsafe food, milk powder, rice, cooking oil, dead pork, fake, and expired mooncakes, expired milk, etc. , and even some domestic famous brands, propaganda 'victory by wisdom, victory by Germany' big companies are selling tainted milk, China user who really don't know what to believe and who should not trust, the whole image of the Chinese brand hit hard.
