Causes and Control Measures of Carbonization of hot melt adhesive compound machine

The use of hot melt adhesive compounding machine has largely improved our production efficiency, but various problems are inevitable in the process of use. Let's share the reasons and treatment methods for carbide in hot melt adhesive compounding machine.   There are many reasons for hot melt adhesive carbonization of hot melt adhesive compounding machine, of course, the main reason is still the temperature, whether the temperature is too high or too low is the induction factor, of course, the stability of glue is also on the one hand. So how can we avoid producing too much carbon?   There are two ways of hot melt adhesive of different product types in the plastic box of hot melt adhesive compounding machine. For the above reasons, we need students to do the following in the process of daily use of glue:   Glue temperature can set according to the regulations of the relevant technical parameter value, has the phenomenon of abnormal behavior such as carbonization temperature and working temperature difference, the lid of the plastic box shut down at any time, so as not to affect the surface of high temperature hot melt adhesive and direct contact with the fresh air, accelerated oxidation, long a small amount of glue, glue the adding amount of hot-melt adhesive in the cabinet without too much, Between 1/3 to half of the occurrence of multiple times can be added, has not been repeatedly heated hot melt glue for a long time after cleaning out the new glue, do not use the other two methods of different social properties of hot melt glue.   The adhesive lining of hot-melt laminating machine is made of uniform hot-melt adhesive bonded on the fabric surface.   When used, the bonding lining is trimmed to the desired shape and size, and the side of the hot melt is applied to the back of other fabric materials (fabrics).   It is lined in the inner layer of clothing, as the skeleton of clothing, simplify the production process and time of clothing processing, so that clothing enterprises have lightness, beauty, shape protection, washing resistance, wear resistance and other aspects of the opposite effect. Interlining processing for general requirements of hot melt adhesive has colorless and tasteless, soft texture, fast bonding, dry and wet washing, adhesive does not affect the brightness of the fabric and other characteristics.   Interlining processing can use a variety of hot melt adhesive, almost all types of hot melt adhesive can be used, which are widely used ethylene - vinyl acetate (EVA) hot melt adhesive, polyamide hot melt adhesive and high pressure polyethylene (HDPE) hot melt adhesive powder, hot melt adhesive used for different purposes and processing methods are also different.

The Difference Between PUR Hot Melt Adhesive Laminating Machine and Water Base Adhesive Laminating Machine

What is the difference between the film forming property of hot melt adhesive laminating machine and water-based adhesive laminating machine? This time we will analyze the difference between the two through modeling.   Water-based adhesive compounding machine is made of water-based adhesive or natural rubber. Integral coating, low wash-ability. Polyurethane adhesive is mainly used in clothing, automotive interior, home textiles, industry.   Hydraulic adhesive compound machine is mainly used in shoes and hats, fiber, luggage, car interior, carpet and other industries.   The oil binder laminator mainly transfers the polyurethane adhesive to the cloth in the form of dot.   It has the advantages of good firmness, washing resistance, softness, strong air permeability and no deformation. Waterborne adhesive is different from waterborne coating adhesive.   Acrylic or polyurethane resins are emulsified with water as solvent through a special emulsifying device.   Its advantage is breed much, environment is friendly, the price is cheap, paint has a lot of water-soluble adhesive, be like water-soluble PA, water-soluble polyurethane and leather adhesive, tramp wax, shave shave the functional medicine ointment such as cream.   Water-soluble coatings will become the development direction of coatings in the future because of their functionality, environmental protection and low price.   Disadvantages are poor film forming, poor washable, and polyurethane can not be stuck in the hot gas sol.   The oil coating adhesive is prepared by dissolving acrylic acid or polyurethane in an oil solvent (toluene, DMF, butane, etc.).   Its advantages are good film forming, good firmness, polyurethane sticky hot air adhesive is currently widely used paint adhesive.Disadvantage is the use of solvent oil, so the environment is not high. In particular, the price of petroleum solvents continues to rise.   Most paints are expensive and the solvent oils used are of poor quality, which is not enough to protect the environment.   In addition, with the further improvement of environmental protection standards in various countries. Therefore, the environmental requirements of paint adhesive are becoming higher and higher.   Hot melt adhesive composite machine mainly continues to be coated on water-based rubber, used for winding composite materials, washing strength is not high.   Mainly used in clothing, automotive interior, textile, industry, water adhesive and other industries, mainly used in shoes and hats, textile, luggage, automotive interior, carpet and other industries. The fabric is transferred to other fabric layers mainly in the form of polyurethane adhesives. It has the characteristics of good water resistance, washing resistance, softness, strong air permeability and no deformation.   The difference between adhesive and hydrogel calendering machine is that water-based coating adhesive is made of water-based solvent and acrylic or polyurethane resin emulsified by special emulsifying device.   This composite material has the advantages of uniform coating, surface composite, no stretching deformation, no stretching, foaming, wrinkling, soft, breathable, clean, thin, washing, suitable for fabric stickers, wool stickers, fabric P, etc. (such as leather, foil, spandex).   Different from the establishment of diplomatic compound machine, hot melt compound machine is an important aspect of electrical safety, non-professional electricians can not open the electrical box for maintenance, wiring, maintenance and so on to strictly abide by the electrical safety operating procedures.   Otherwise it could cause electric shock or fire. In case of fire, the power supply must be cut off immediately and dry powder fire extinguisher must be used to extinguish the fire.   If someone is electrocuted, rescue him or her according to the electrical operation regulations and send him or her to the hospital.   Cabling and operation must be carried out in strict accordance with instructions.   Otherwise, the equipment may be damaged (due to the partial power supply of the equipment, the motor driver may be single-phase 220 v AC).   Persons operating and maintaining equipment should take appropriate measures for their own safety.   They must wear sleeves, cotton, overalls and gloves. If you burn yourself, apply hot cream immediately.The injury is serious and must be taken to hospital immediately after application of hot ointment.When applying adhesive to skin, do not remove it or soak it in water.

Dry composite machine is generally used in the process of sticking high elastic underwear cloth with sponge flat fabric

Dry composite machine is generally used in the process of sticking high elastic underwear cloth with sponge flat fabric, of course, there are other scenes will also be used, such as waterproof and breathable film TPU, PU material is fitted with various bottom and surface cloth; As well as denim fitting shaker fleece, flat woven fabric, knitted fabric and other clothing materials of fine fitting processing and so on.   Judge the advantages and disadvantages of a product, the first thing to judge is the advantages and disadvantages of the material chosen to use this product, the main role of dry composite machine is to improve the quality of the material, the product is more high-quality.   Dry composite machine can synthesize two kinds of materials into a new material, relative to a certain kind of material before, must be a lot, this is also the reason why many manufacturers choose to use dry composite machine. The following dry compound machine manufacturers continue to understand the necessity of compound processing with you.   Take apparel for example, composite processing combines fabric with fabric or fabric with film.   First of all in wear-resistant and washable than a single fabric to do raw materials much superior.   And if sports clothing, such as mountaineering clothing fabric is more need composite processing, because mountaineering clothing not only need wear-resistant water resistance, but also warm, breathable, moisture permeability, windproof and other functions.   Car cushion materials also need to be composite processing.   Fabric or leather as a surface cloth, and foam is soft, elastic and good characteristics. And because of the use of composite glue with fire prevention function, so there is a certain guarantee of safety performance, so made of car seat than ordinary car seat market competitiveness.
