What is the purpose of polyurethane rubber rollers? Which industries use polyurethane rubber rollers

Polyurethane rubber rollers have the advantages of wear resistance, corrosion resistance, good elasticity, etc., and are suitable for supporting rollers of new materials such as varnishing, oiling, metallurgy, and iron printing of imported equipment. Polyurethane rubber rollers are suitable for all types of machinery and have many superior characteristics.

1. The hardness index of the product is wide, from HSA15 to HSD95, which can meet the hardness requirements of different types of mechanical rubber rollers.

2. The colloidal surface of the product is fine and smooth, the appearance is bright, and the colloidal material and mandrel are firmly bonded. The size of the rubber roller is strictly controlled, and the size does not change greatly with temperature and humidity. It can adapt to the high temperature and high humidity environment of the southern workshop and the cold and dry climate conditions of the north.

3. The product has good chemical properties and is suitable for various types of inks and printing methods. It has special resistance to solvent components in various inks, dampening solutions, and cleaning agents. Polyurethane rubber rollers are also suitable for UV ink rubber rollers and varnish oil rubber rollers, especially for boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol and salt water solutions have good solvent resistance.

However, it is not resistant to acetone, ethyl acetate and strong acids and bases.

4. The colloid for polyurethane rubber roller has sufficient surface viscosity, which can ensure that the rubber roller has good ink transfer and inking performance in the printing process, and its good ink philophilic performance can ensure high-quality printing.

5.Polyurethane rubber roller has excellent physical properties, long-term use of rubber roller will not harden, aging, and tear resistance, good resilience, excellent wear resistance, so long service life, easy to preserve, long-term storage does not affect the use effect; It can withstand high pressure, high speed, high temperature and high humidity production environment. Experiments show that the tensile strength and wear resistance of polyurethane rubber rollers are 3 times and 5 times that of natural rubber rubber rollers. Compression set, good resilience; The service life of polyurethane rubber roller is more than 1 times that of general rubber roller.

6.The polyurethane rubber roller is easy to clean, easy to convert dark and light inks, and convenient for printing and color change.

7.Polyurethane rubber roller has excellent hydrophilicity, so it can be used as a rubber roller for water and alcohol dampening system, and the effect is very good.

Precautions for use.

1.During use, avoid contact with solvents such as ethyl acetate, butyl acetate, acetone, butanone, etc., as well as strong acids and alkalis.

2.When installing the rubber roller, it should be corrected to a parallel position, and the pressure between the rubber roller and between the rubber roller surface and the layout must be uniform.

3.When storing the rubber roller, a special rubber roller holder must be used to ensure that the surface of the rubber roller is not pressed and does not contact any other objects for a long time.

4.After each day of shutdown, the paper wool and ink residues on the surface of the rubber roller must be cleaned with cleaning solution.

Metallurgy, printing will use polyurethane rubber rollers, and many industrial machinery will also use polyurethane rubber rollers.

In industry, polyurethane has a wide range of uses.

I know that Kemai rubber roller factory is specialized in polyurethane rubber rollers.

Mainly used in metallurgy, printing, machinery and other high-pressure environments, polyurethane rubber rollers can be customized according to the use of various solvent-resistant, low-temperature resistant rubber rollers.

Generally, it is customized according to the use environment of the rubber roller.

Guangdong rubber roller factory has a Kemai rubber roller, which is not bad!

Printing industry, printing and dyeing industry.

Chuzhou rubber roller.

Polyurethane can be used as a sliding door, pulley and other small parts, precision instruments, polyurethane rubber rollers.

Generally, it is used in the coating machine, the precision is high and low, and the general good export products should be controlled between 2-5 filaments.

Let's talk about the advantages of polyurethane High strength, high wear resistance, high oil resistance (this is not possible with general natural rubber, but generally toluene is more used as a mixture, because toluene is cheap)!

If the hardness is not as hard as we are now, we can do it at 15-95 degrees!

If your requirements are not very high, it is better to replace other rubber with others, **poor.

China's polyurethane industry ranks first in the world.

A few days ago, the "2013 Polyurethane Elastomer Annual Meeting" of the Elastomer Professional Committee of China Polyurethane Industry Association was held in Xining Hotel, Xining City, Qinghai Province. Zhu Changchun, Secretary-General of China Polyurethane Industry Association, said: "In 2012, affected by the global financial turmoil, the chemical industry experienced a severe test, with a significant slowdown in economic growth and a significant decline in economic efficiency.

However, the polyurethane industry still maintained a good growth rate and showed a steady growth trend. According to the statistics of the secretariat of the association, except for some raw material products affected by the rapid expansion of production capacity, the growth rate of most products exceeded 10%. In 2012, the national polyurethane production and sales reached 7.8 million tons, including 3.2 million tons of polyurethane foam, 350,000 tons of spandex, 1.95 million tons of polyurethane synthetic leather slurry and sole stock solution, 1.3 million tons of polyurethane coatings, 400,000 tons of polyurethane adhesives and sealants, and 600,000 tons of polyurethane elastomers, an increase over 2011, of which the growth rate of polyurethane elastomers exceeded 20%.

By the end of 2012, the production and sales of polyurethane accounted for more than 40% of the world's total output, ranking first in the world.

1. It has excellent wear resistance.

2. Wide range of hardness: the hardness of polyurethane products is about 10-D80 Shore A, while the hardness of ordinary rubber is generally A60-100 Shore A. It is worth noting that polyurethane elastomers can have an elongation of 400-800% in this hardness range.

The highest hardness of natural rubber is 70 Shore A70 when the elongation is 550.

3. High strength and high elongation.

4. Excellent oil resistance: the oil resistance of polyurethane products is better than that of cyanide rubber; The aging resistance is better than that of natural rubber and other synthetic rubbers; In terms of hydrolysis resistance, acid resistance, alkali solution corrosion resistance, polyether type PUR is better than polyester type PUR.

5. It has the excellent characteristics of light capacity, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-water absorption, simple and fast construction, and has become an indispensable material for thermal insulation, waterproof plugging and sealing in construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors.

Uses: Widely used in vehicle manufacturing, metallurgical manufacturing, mining machinery, construction machinery, chemical machinery and other industries.

It is mainly wear-resistant, anti-static, and is generally used in the textile industry.

The most prominent features are wear resistance, high pressure resistance, and low temperature resistance

It is used in metallurgy, machinery, printing and other industries.
