It take a compressed gas as the power to form a high-speed jet to shoot glass beads on surface of work-piece that causes changes on surface and shape of the work-piece. Due to the glass beads` impact to surface, it makes the surface a certain of cleanliness and different roughness.
• It improves the mechanical properties of surface so as to enhance the fatigue-resistance of work-piece.
• It provides with parts-surface a controllable rough-surface to increase the adhesion with the paints, to extend the durability of the paints and it is also benefit to the flow and decoration of paints.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

The company said in the statement: "We are looking for and will try to obtain alternative materials for butadiene monomer. At present, we do not know how long this will last."
Butadiene (BD) is a monomer raw material for many chemical polymers and is a key raw material for the production of styrene-butadiene rubber (SBR). It can be used in the production of automotive tires, automotive belts, automotive rubber tubes and many other products.
At the beginning of this year, some manufacturers adopted sales control measures because of production problems. In addition, Libya restricted C4-type crude oil in the first quarter, which is the reason for tight supply. C4 crude oil is a raw material for BD production.
It is reported that the market price of BD has risen to 2 US dollars / pound (4409 US dollars / ton). In June, the supply contract showed that the contractual price agreed between the contracted parties (ie buyer and seller) was between $1.50 and $1.65 per ton. 
Goodyear tires face shortage of raw materials for tires
Goodyear Tire & Rubber Co., the largest tire manufacturer in the United States, has announced that Goodyear is facing a shortage due to its suppliers' production of raw materials styrene butadiene rubber (SBR) and other butadiene derivatives. Force majeure factors influence.
