<p>Construction process of roller encapsulation</p> <p><strong>1. Polishing the roller</strong></p> <p>Clean up the residual glue on the roller, then use a special grinder to polish a rough surface without rust on the roller, and finally use a fiber disc to lightly polish it. </p> <p><strong>2. Clean the noodles</strong></p> <p>Sweep the polished surface clean with a cleaning brush, and then clean it with a non-toxic flame-retardant cleaning agent to ensure that there is no residue on the surface of the roller. If there is water on the surface of the drum, let it dry. </p> <p><strong>3. Apply adhesive</strong></p> <p>First, apply the metal treatment agent thinly and evenly on the polished surface of the roller, and let it dry completely. Then mix the adhesive in a specific proportion evenly, apply forcefully and evenly on the cylinder once, wait for it to dry completely, and then paint a second time, and also paint on the surface of the rubber sheet. </p> <p><strong>4. Paste the rubber sheet</strong></p> <p>When the adhesive dries to slightly sticky but does not adhere to the back of the fingers, paste the rubber sheet, and roll it with a compaction roller, use a rubber hammer to beat the rubber sheet firmly to ensure that there are no bubbles inside, and finally fill it with a glue gun Seams, and polish the edges. </p>

<p>It can be widely used to clean printed boards, glass products, steel plates, aluminum plates and other panels. The sponge roller has many micropores, and the micropores are connected to each other, and the water absorption is very good. For oily substances, since the oil is an organic compound, when it penetrates into the sponge roller hole, it forms a closed state. It cannot absorb the grease better. The oil absorption is not good. The ink is dyed in the water, and the printing machine depends on water. The penetrating and flowing performance of the ink drives the dyes of the ink, and the poor penetrating performance of the dyes is left on the paper. The moisture is transparent and colorless, leaving only the dye marks. The paper just printed is moist.</p>

<p>Polyurethane rubber has a wide range of hardness, as low as low modulus rubber below Shore A10, and high impact elastic material as high as Shore D85. Its elastic modulus can be as high as hundreds of megapascals, which greatly exceeds others. The elastic modulus of rubber is in the range (approximately 0.2-10 MPa), so polyurethane rubber has a wide range of properties and is a type of polymer material ranging from rubber to plastic. It is also precisely because of polyurethane's outstanding characteristics of wear resistance, oil resistance, aging resistance, low temperature resistance, high hardness, and high elasticity. In recent years, the amount of polyurethane has increased rapidly, and the scope of application has continued to expand. It is widely used in petrochemical, mining machinery, and light industry. Machinery, water conservancy engineering, transportation and shoemaking, papermaking, electromechanical and other industries have replaced and saved a large amount of wood, steel and various rare metals. However, the existing polyurethane rubber rollers are not ideal for use in some special environments. Especially when used for a long time and under high speed conditions, its high temperature resistance, friction resistance, and corrosion resistance performance will be significantly reduced. For example, the polyurethane parts used in foreign high-speed cigarette equipment imported from our country have to run for a long time under the condition of high speed, and the wear of the parts is more serious. The use time is only 20 to 35 days, which not only affects production efficiency, but also has zero The components are all imported, so the running cost is higher</p> <p>The purpose of the present invention is to provide a polyurethane rubber roller with superior performance in terms of wear resistance, corrosion resistance and high temperature resistance. </p> <p>Compared with the prior art, the present invention has the following advantages and effects. By adopting the above scheme, the formulated polyurethane product has extraordinary wear resistance, high temperature resistance, corrosion resistance, aging resistance and other properties, and its wear resistance is natural rubber The comprehensive performance of its products is 10 times that of rubber products, and the price is only 1-2 times that of general rubber, especially the polyurethane rubber roller formulated with the above formula, in the working environment of high speed and spraying industrial glycerin , There is no change after three months of use. However, the existing ordinary polyurethane rubber rollers cannot be used due to foaming or severe abrasion in less than one month. Its comprehensive performance is also superior to similar foreign products, and the cost is low. It is an ideal product that can completely replace imports. </p>
