Printing roller mixed glue

        Printing roller mixed glue is a bundle of excellent oxygen resistance, weather aging, chemical corrosion, high elasticity, high strength, high extension of silicone raw materials, according to the different parts and functions of the sealing strip, in actual applications in actual applications , Add sulfide, protection, reinforcement, operating system materials and special given materials to EPDM materials. So, how to process the print roller mixed glue? First of all, if the silicon rubber wants to be put into production, a sulfide is required to be added to the vulcanizer type. There are two ways to add sulfur: Sulfur with silicon rubber with less than 50 kg can add a certain amount of sulfurizer to the driving machine, and the mixed surface will be smooth; the silicon rubber with more than 50 kg must be pinching the co -with Add vulcanizers until the mix is evenly mixed on the surface of the drum until the surface is smooth. The docking of printing roller gel and downstream rubber products manufacturers has promoted the upgrade of my country's rubber industry.

        The demand for printing roller compound rubber is large and the purchase volume is not small. However, when buying and storing large quantities, the warehouse should maintain natural ventilation, and it should not be exposed to the sun. The room temperature should be low, and pay attention to lowering the temperature in summer; , and move some individually on time to avoid sticking together and let the internal heat dissipate; the storage time should not be too long and should be used as soon as possible. Printing roll mixing rubber is a material used in the production of rubber products, so their quality is related to the quality of the entire rubber product. Such products will encounter many problems in the production process, and they will directly affect the quality. For better production, we need to understand the problems that are prone to occur in the production process. Maoming printing roll compound rubber supplier Printing roll compound rubber is refined through rubber materials and then continues to be used in the production of such products, which has a good recycling value.

       The current situation of the printing roll compound rubber market: At present, many printing roll compound rubber manufacturers in the world have taken a fancy to China, a big consumer of rubber products, and have set up production centers in my country, hoping to apply their own technical advantages directly to mainland China. market. Judging from the operation of these international manufacturers, their rich industry experience gives them considerable advantages in technology research and development, product and market integration. These manufacturers have spared no effort in developing the market. An international manufacturer only has dozens of types of mixed rubber for printing rolls, which is unimaginable for domestic manufacturers. And these large-scale manufacturers did not stop there, they are still exploring the market demand, and carry out the production of printing roll compound rubber in a targeted manner. However, while these international manufacturers are expanding wildly, the current situation of my country's printing roll compound rubber industry is not very optimistic. The rubber products used in automobiles, the printing roll compound rubber required for it is still imported in large quantities. On the contrary, the overcapacity of general-purpose products has exceeded the capacity of the market.

        The so-called printing roll compounded rubber refers to the uncrosslinked state in which the compounding agent is mixed in the raw rubber of bulk, granular and powder, and has fluidity. The raw rubber or plasticized rubber mixed by the rubber mixing machine according to the formula and the compounding agent is called the printing roller mixed rubber. The printing roll compound rubber is a blank for manufacturing rubber products, that is, a semi-finished product. Therefore, the colloidal dispersion quality of the printing roll compound rubber is directly related to the quality of the finished product. At the same time, the viscoelasticity and rheology of the printing roll compound rubber directly affect calendering, Processing technology such as extrusion. The printing roll compound rubber is a blank for manufacturing rubber products, that is, a semi-finished product. Therefore, the colloidal dispersion quality of the printing roll compound rubber is directly related to the quality of the finished product, while the viscoelasticity and rheology of the printing roll compound rubber directly affect the rubber compound. Operation and processing performance and post-production molding, extrusion, calendering, extrusion and other processing technology. The macromolecules of the rubber whose "stress" is relaxed during the mixing process of the printing roll compound accumulates structural fatigue due to the action of external mechanical forces.

Speaking of printing roller mixing rubber, I think of rubber products used in various machinery and equipment, as well as rubber trees in Thailand. Today, when the rubber is harvested, the raw materials on the market should be sufficient, but the continuous rise in domestic prices has made major manufacturers expand wildly. The current market situation is not optimistic. Production situation of printing roller mixing rubber: In the production process of rubber products, the rubber raw materials are first added to the rubber mixing machine, and various compounding agents are mixed at the same time, mixed according to a certain formula and proportion, and then pressed into shape. It can be said that the quality of the rubber compounded by the printing roll directly determines the quality of the rubber products. Printing roller compound rubber enterprises need to broaden the source of technology, narrow the gap with international manufacturers in equipment, technology, and technology, and tap the application of printing roller compound rubber in the production of rubber products such as oil seals and oil pipelines, in order to occupy a place in the market. . Printing roll mixing rubber mixing is a key process in rubber compound processing.

        Does the printing roll compound need to be kneaded twice? If a sheet product is produced, no secondary kneading and mixing is required. Compound rubber compounding. According to the recipe, first put the raw rubber into the kneader and mix, then add half of the silica used in the recipe for mixing. After mixing the white carbon black into the raw rubber, add the structure control agent, the other half of the white carbon black and other auxiliaries in turn, and take it out for use after mixing evenly. ② mix. Blending is mainly done by adding vulcanizing agents and pore formers to the compound, usually done on a two-roll mill. After the mixed rubber is recovered on a two-roll mill, add a vulcanizing agent according to the formula to mix evenly, and then add a pore-forming agent to mix while controlling the roll distance (the roll distance is controlled according to the particle size of the pore-forming agent). After mixing evenly, remove and set aside. ③ Rubber sheet. According to the requirements of the mold, prepare the rubber sheet of the corresponding thickness, and then cut it.
