Supplier of compounded rubber: Factors affecting the compounding process

2022-07-08

During the mixing process, the mixing temperature of natural rubber is generally controlled around 130℃, and the discharge temperature is usually controlled within the range of 130~145℃. If the temperature is too low, it often causes the rubber material to not clump under pressure; if the temperature is too high, it will soften the rubber, which is not conducive to the dispersion of filler quality. Therefore, the rubber mixing suppliers need to pay attention to the control and adjustment of cooling water or heating steam according to the process requirements, in order to control the temperature of the mixing chamber.

Supplier of compounded rubber: A brief introduction to compounded rubber

2022-06-23

The mixing rubber supplied by the supplier is a well-known high-performance rubber, especially known for its excellent resistance to high temperatures, ozone, weather, oxidation, mineral oils, fuel oils, hydraulic oils, aromatics, and many organic solvents and chemicals. The FKM system from the mixing rubber supplier is now available in blends such as normal (66% F), medium F (67-68.5% F), high F (70% F), improved low-temperature elasticity (64.5-67% F), and excellent additional chemical and solvent resistance (66% F).

Some knowledge points about polyurethane blended rubber, explained by the blended rubber manufacturer.

2022-04-25

Polyurethane blended rubber is a type of mixed polyurethane rubber (referred to as MPU) synthesized from polyether polyols and methylene diphenyl diisocyanate (MDI) with an unsaturated structure. The vulcanization system can choose between peroxides or sulfur. The processing technology and vulcanization molding processes and equipment are the same as those for general rubber; it is suitable for manufacturing rubber products with hardness ranging from Shore A 50 to 95.

The process and characteristics of compound rubber, as told by the compound rubber manufacturer.

2022-04-11

The manufacturer of mixing rubber believes that mixing is the process of using the mechanical force of a rubber internal mixer to evenly disperse various compounding agents in the rubber. The mixing process is to evenly disperse various compounding agents in the rubber, forming a medium of rubber or a mixture of rubber with some compatible components (compounding agents and other polymers) as the medium, and a multiphase colloidal dispersion system with incompatible compounding agents (such as powder fillers, zinc oxide, pigments, etc.) as the dispersed phase.

A one-minute explanation by the rubber compound supplier about what rubber compound is.

2022-04-02

The so-called compounded rubber refers to a type of unvulcanized rubber that has fluidity, in which the compounding agents are mixed in block, granule, or powder form. According to compounded rubber suppliers, the rubber material that is mixed with the compounding agents according to the formula using a rubber mixing machine is called compounded rubber. Compounded rubber suppliers indicate that compounded rubber is mainly used for automotive parts, front and rear main shaft oil seals, front and rear crankshaft oil seals, power steering pump seals, transmission pump seals, dust covers, power steering hoses, and 175-degree radiator hoses.

The UV adhesive manufacturer will introduce the curing time of UV glue and the reasons for whitening.

The UV adhesive manufacturer will introduce the curing time of UV glue and the reasons for whitening. Users should pay attention to taking protective measures to avoid discomfort and allergies caused by operators talking on the phone for long periods. It is recommended to maintain good air circulation in the workplace where UV glue is handled. If cost is not a concern, UV adhesive manufacturers can focus on the selection of raw materials to produce products with relatively low odor; however, it is very difficult to achieve a completely odorless product.

What are the characteristics of the coating roller rubber?

The coating roller glue technology is widely used in various packaging, from medicine boxes, craft boxes to outer packaging boxes and various product packaging. The coating roller glue process includes pre-coating, dry composite, and wet composite. Among them, pre-coated film is rarely used due to its high cost.

A method for producing a UV-specific adhesive curing device.

UV special adhesive, also known as photosensitive adhesive and UV curing adhesive. Shadowless adhesive is a type of adhesive that can only be cured by ultraviolet light. It can be used as an adhesive, as well as a compound for paints, coatings, inks, etc. The curing principle of UV special adhesive is that the photoinitiator in the UV curing material absorbs ultraviolet light, generating active free radicals or cations, which initiate the polymerization and cross-linking chemical reactions, causing the adhesive to change from liquid to solid within seconds.

A method for making a UV adhesive coating machine.

UV adhesive, also known as photosensitive adhesive and ultraviolet curing adhesive. Shadowless adhesive is a type of adhesive that can only be cured by ultraviolet radiation. It can be used as an adhesive, as well as a compound for paints, coatings, inks, etc. Ultraviolet light is invisible to the naked eye and is a segment of electromagnetic radiation outside of visible light.

Overview of the Coating Roller Rubber Lamination Process and Machinery

The lamination roller glue for paper prints is one of the post-printing processing steps. Under the pressure of rubber rollers and electric heating rollers, the paper adheres to the plastic film coated with adhesive, forming a paper-plastic integrated product. After coating, the surface of the printed material appears smoother and shinier, significantly enhancing the gloss and durability of the print, extending the product's lifespan, and providing protection against water, stains, wear, folding, and chemical corrosion.

The process and precautions of the board film covering roller rubber technology.

The film coating roller technology has been widely used in China since the 1960s, and then it was widely applied in post-processing of printed products such as high-end packaging boxes, paper bags, and book covers. With the development of technology, people in the domestic printing industry began to realize the disadvantages of oil-based film coating machines, leading to the emergence of water-based film coating machine technology.

Analysis of Problems and Solutions of Coating Roller Rubber

During the printing process of self-adhesive labels, printing failures occur from time to time due to the relatively complex structure of the printing machine itself, as well as various factors such as materials, processes, environment, and the skill level of personnel. A failure may be caused by multiple reasons, and a single reason may lead to multiple failures, making troubleshooting quite difficult. Although there are some failures that cannot be resolved at present, most can be eliminated, and the methods for elimination are not complicated.
