Application of sponge sand in grinding and polishing industry

Hubei Fengpu Grinding Technology Co., LTD. Zhao Zhongjin

With the rapid development of coated grinding tools industry, more and more varieties of grinding products, people's requirements for grinding and polishing surface quality is increasingly high, some new materials, new technology gradually applied to different fields of grinding industry. Usually use the most common sheet water resistant sandpaper and coated dry abrasive paper, after continuous improvement, update has done very well, applied to various fields of industry and civil, in grinding polishing can be said to be "omnipotent". But with the pursuit of the object surface grinding effect reputation, sandpaper in the grinding of limitations increasingly prominent. So people are always looking for better grinding products. Because sponge sand has many characteristics different from ordinary sandpaper, sponge sand research and development success and enter the polishing industry, by more and more people's favor. Next I briefly introduce the sponge sand launched by our Fengpu grinding in the grinding and polishing industry.

First, the concept of sponge sand

There are two types of sponge sand:

One is sponge as the matrix, directly coated on the sponge and made of rubber sand, and then converted into various shapes and specifications of sponge sand products.

One is TPU film as the back base, coated in plastic sand on the film substrate to make a thumb roll, and then combined with the sponge.

Two, the characteristics of Fengpu grinding sponge sand:

▲, the use of high softness TPU film as the back base, high density and high quality sponge as the substrate, environmental protection type tree ester glue. Good resilience, plasticity, not easy to crack, not off the sand, resistant to rubbing. Semi-open sand planting structure, better blocking effect.

▲, elastic substrate to avoid excessive force and prevent excessive grinding, resulting in grinding object surface wear or depression phenomenon.

▲, lower grinding temperature, better adhesion, grinding products smooth surface, produce high quality gloss.

▲, because the product has good elongation and tensile strength, there is a strong bending performance, suitable for grinding any irregular geometric surface. For example, contour surfaces, arcs, curved surfaces and hard-to-reach areas can reduce edge wear.

▲, a wider range of use, greater flexibility: suitable for dry grinding, wet grinding, manual and machine grinding.

▲, uniform sand, strong wear resistance, long continuous sharpness, grinding surface consistency. It is an ideal new grinding product.

Three, the product form

▲, disk, square, strip, roll

▲, double-sided sand, single-sided sand

▲, commonly used is mainly composite sponge, also have separate composite flannelette.

Grain size range: P80----P1200

Four, sponge sand in the industry application

▲, wood building materials home decoration industry. Main product form: double-sided sponge sand. For example: furniture, wooden doors, stairs, decoration and other wood lacquer surface grinding.

▲, automobile manufacturing plant, automobile repair, automobile parts, automobile decoration materials and other grinding and surface treatment. Main product forms: disk sand with holes, box sand, sand roll, etc

▲, surface grinding and polishing of electronic products. For example: mobile phone, computer shell, circuit board, contact end face and so on are widely used in burring, scratches, polishing, paint smooth surface.

▲, in plastic, artificial marble, Musical Instruments and other industries also began to apply.

In addition in the metal, manufacturing industry for rust removal, decontamination, paint, polishing and so on is also very ideal grinding material.
