PU glue has excellent bonding fastness, good heat and weather resistance, colorless and translucent, environmentally friendly, non-toxic, easy to operate, and suitable for assembly line production. There are mainly water-based PU adhesives and oily PU adhesives. PU adhesives are mainly produced by reactors and are mainly used for bonding of PU materials such as PVC, TPR, rubber, nylon cloth, ABS, and synthetic leather.
As a typical main reaction equipment in chemical production, the reactor is used to disperse and mix a variety of materials through stirring, heating, and cooling, so as to carry out reaction polymerization and so on. Realize the heating, evaporation, cooling and low-speed mixing functions required by the process. Subsequently, the pressure requirements in the reaction process have different requirements for the design of the container. Stainless steel reactors are different according to different production processes and operating conditions. The design structure and parameters of the reactor are different, that is, the structure of the reactor is different.
The reaction solvent can be put into the inner layer for stirring reaction, and the interlayer can be passed through different cold and heat sources (refrigerated liquid, hot water or hot oil) for cyclic heating or cooling reaction. Through the interlayer of the reactor, a constant temperature (high temperature or low temperature) hot melt or cooling medium is injected to heat or cool the materials in the reactor at a constant temperature. At the same time, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use. The materials are reacted in the reaction kettle, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the materials can be discharged from the discharge port at the bottom of the kettle, and the operation is extremely convenient.
Reaction kettle product classification: The reaction kettle is the main reaction and stirring equipment in chemical production. Generally, there are stainless steel reaction kettles, carbon steel reaction kettles, multifunctional stirring kettles and other structures:
1. Transmission mechanism: motor, reducer, frame, coupling, bearing, connecting plate, etc.
2. Reaction vessel (kettle body): Determine the thickness of the plate according to the capacity and material reaction requirements design pressure; the material is generally stainless steel (304 stainless steel, 321 stainless steel, 3. Heat transfer device: jacket, inner coil, outer plate Pipes, etc.; heating by means of organic heat carrier circulation (heat transfer oil) or steam, hot water, etc.; cooling by means of cooling water, chilled water, cold heat transfer oil or natural wind;
4. Stirring device: counter-propeller stirring, anchor-type paddle stirring, double-propeller stirring, turbo-propeller stirring, dispersing disc, butterfly paddle, etc.;
5. Stirring speed: The choice of stirring speed depends on the material stirring requirements. Generally speaking, several liquid materials need to be mixed and reacted generally at 50 rpm-85 rpm. If it is required to disperse the powder into the liquid, generally choose 500 rpm-1500 rpm. If it is required to emulsify the oil in water or emulsify and mix two incompatible liquids, generally choose 2500 rpm-3500 rpm.
6. Sealing device: mechanical seal, packing seal or labyrinth seal, etc.;
7. The accessories of the complete set of reactor equipment generally include distillation column, heat exchanger, water separator, etc.

Q : Can you send the formula for the products we want to make ?
A : Our machines can be used for many kinds of product making ,such as Resin , Paint, Adhesive Cosmetic , Food , Chemicals . There are many kinds of these products , so it's impossible for us to know all the formulas and technologies . We can assist you to find the raw material list you need , and after you place order with us , we can help you to find formula and technology , there will engineers to teach you how to make the product , and the cost will be on your account.
Q : Do you have machines in stock ?
A : Yes , but just the small-scale machines Machines are different with other products , most of the large-scale machines are designed according to our customers 'requirements different customers have different production requirements , so the technical parameter is different for most machines On the other hands , most of the our machines will cover a large area , so once the machines are finished , we will effect shipment after QC .
Q : Can you send the detailed drawings of the machine to us before we place order ?
A : We can send you a draft drawing of the machines , and after you place order and pay the deposit , our engineer will design the send you the detailed drawings . Once you confirm without questions , we will put it into production.
