Adhesive: A kind of substances, natural or synthetic，organic or inorganic, which connects two or more parts or materials together through the interface adhesion and cohesion. Also known as glue. In short, it is to hold the glued materials together through the bonding effect. "Adhesive" is the general standard term, which include glue, puddle, mucilage glue, glue paste, etc.
Adhesive is consisted of bonding material (also known as the sticky material), curing agent, toughening agent, diluent, filler, modifier and so on. A wide range of adhesive are classified according to different standards as follows:
According to the chemical property of sticky materials of the adhesive , it can be divided into inorganic adhesives and organic adhesives. Sodium silicate, cement, gypsum are inorganic adhesives. The adhesive having polymer materials as the sticky material is organic adhesive
According to the physical state of adhesive, adhesive can be divided into, liquid, solid and paste adhesive. Solid adhesives have powder type and thin film type, and the liquid adhesives can be divided into aqueous solution type, organic solution type, aqueous emulsion type and non-aqueous media disperse type etc
According to the source of the adhesive, it can be divided into natural rubber and synthetic rubber. Natural rubber, asphalt, rosin, gelatin, cellulose and starch glue are natural adhesive. While various adhesives made by polymerization methods are synthetic adhesives.
The common organic adhesives, according to the molecular structure, it can be divided into thermoplastic resin, thermosetting resin, rubber adhesives etc..
According to the adhesives applications, it can be divided into pressure sensitive adhesive, re-wet adhesive, instant dry adhesives, delay adhesives etc.
According to the application temperature of the adhesives, it can be divided into high temperature resistant, low temperature resistant and room temperature using adhesives; And according to its curing temperature, it can be divided into normal temperature curing type, medium temperature curing type, high temperature curing type adhesives.
According to the applications industry, adhesives are mainly divided into civil construction, paper and plants, cars, planes and ships , electronic and electrical as well as medical and health care adhesives.
According to the chemical composition of adhesive, it can be divided into various specific kinds of adhesive, such as epoxy resin adhesives, polyurethane adhesives, poly (vinyl acetate adhesives etc.
Adhesives: potting glue, hot melt adhesive, sealant, white latex, anaerobic adhesive, hardening adhesive, pressure sensitive adhesive, polyurethane, epoxy resin, organic silicone, conductive glue, all-purpose adhesive, polyamide adhesive, plastic film glue, osmotic glue, waterproof glue, fireproof glue, photosensitive glue, building special glue, solar dedicated plastic glue, electronic appliances, automobile special glue, double-sided rubber, silicone glue, etc

Three-shaft Mixer: Suitable for medium-viscosity adhesives (viscosity approx. below 300000 cps ), have butterfly type-and-disperser, anchor type-and-disperser and anchor type-and-disperser-and-paddle type etc; Vacuum, heating, cooling, condensation etc are optional functions.
Planetary Mixer: Suitable for products with high, medium and low adhesives (viscosity maximum up to 5 million cps). Different agitators (paddle type, claw type, frame type, twist type, etc.) are designed for materials with different viscosity. And toothed disc are available if required. Vacuum, heating, cooling, condensation etc are optional functions.
Full specification including lab and production ones to meet the various requirements of adhesive production.
Extrusion Machine: Specially used for adhesives with poor liquidity. And design different extrusion pressure as per the viscosity of the materials, max. can be up to 300T to discharge materials completely without residue. The structure for lifting the tank up and then discharge materials are optional to make it easier to coordinate with the next process, for instance, filling system.
Filling Machine for high-viscosity materials: Packaging specifications ranges from 0.5 Kg to 50 Kg, suitable for containers with different specification and made of different materials including semi-automatic and fully automatic type. It also can customized.
Reaction Kettle: Normal pressure or pressurized vessel for sulfuration, nitration, hydrogenation, alkylation, polymerization, condensation processes; It consists of kettle body, kettle cover, jacket, agitator, driving device, shaft sealing device, bearing (ground support type or platform lug type) and other parts. Different shaft sealing, cooling/heating method and mixing method can be customized.
Powder and Liquid Delivery Systems: powder pneumatic conveying (positive pressure, negative pressure, dense phase, dilute phase), mechanical conveyor (spiral, belts, bucket, etc.); liquid positive pressure and negative pressure conveying, pumping.
Powder, Liquid Batching System: including "incremental method", "decrement method", "volume method" and other batching methods.
