Flap Disc
Flap disc, commonly known as flat emery
cloth wheels, emery discs, flower impellers or elastic grinding discs, are a
large variety of coated abrasive conversion products, which press the cut
coated abrasive sheets one by one. It is formed by sticking adhesive to the
back cover plate along the circumference. The flap disc are called strong
elastic grinding discs. They are made of calcined emery cloth, which uses mesh,
nylon, plastic, steel paper and other materials as the base. Attached abrasive
tools, evenly distributed in a fan shape to ensure the best grinding effect.
The particle size is 36#-320#, 60# and 80# are the most common, and the outer diameter
is 4"-7" installed on the angle grinder. Angle grinders are mainly
installed on hand-held Power Tools to polish and polish welds, burrs, chamfers,
surface rust removal, and surface polishing of various metal and non-metal
parts.
The flat emery cloth wheel (flap wheel) is
formed by sticking multiple emery cloth sheets on the tray in a fan-shaped
superimposed arrangement, and the bonding angle between each emery cloth and
the tray plane is 10°-30°. The emery cloth arrangement of the utility model can
make When the abrasive cloth wheel grinds and polishes the workpiece to be
processed, the cutting angle is optimized to ensure that the base material of
the abrasive cloth wheel and the grinding are consumed simultaneously, which
obviously improves the overall wear resistance and grinding efficiency of the
flat abrasive cloth wheel, and prolongs the service life of the abrasive cloth
wheel. Grind the surface of metallic and non-metallic materials.
product advantages:
Compared with the resin grinding wheel for
fixed abrasives, it has the advantages of polishing and polishing at one time,
shortening the operation time, saving the grinding cost, high efficiency, good
heat dissipation, high grinding efficiency, reducing operator fatigue,
increasing machine life, etc. It has strong elasticity, High tensile and
bending strength and good grinding effect. The grinding speed is fast, the
effect is good, and the noise during grinding is low. It is suitable for
various industries or fields of manufacturing such as major metal parts
factories and machinery factories. Good weather resistance, salt spray
resistance and heat resistance, suitable for use in different regions.
Scope of application:
It is suitable for polishing of stainless
steel, metal, metallurgy, automobile, wood, marble and other industries. It is
especially suitable for the processing of stainless steel and can replace the
resin-shaped grinding wheel. It has strong elasticity, high tensile and bending
strength, good self-sharpening, high grinding rate, and low noise. It is
suitable for welding seams in the box. Polishing of the edges.
There are different classifications of
louvers according to different angles. The following are two common
classifications:
According to the appearance: T27 VS T29
Flap disc generally have two shapes, curved
and flat.
The flap disc type is also called the T27
type, and the curved type generally refers to the T29 type.
The flap disc type (T27) has a flat
surface. It is mainly used to polish the flat surface and the external edges
and corners. The flap disc and the workpiece are angled during work, which can
complete the grinding and polishing at one time, reducing the work flow.
The curved surface of the curved louver
(T29) has an upward arc, which makes the T29 flap disc have a better cutting
ability on the plane. When working, the T29 type grinding wheel forms an angle
of 15° to 25° with the grinding surface, which is mainly used to deal with the
grinding of contours and edges. When there are higher requirements for speed
and cutting ability, T29 flap disc is undoubtedly the best choice.

According to the type of abrasive
particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected,
the flap disc can be divided into three types: ceramic alumina, zirconium
corundum and alumina.
Because ceramic alumina itself has many
crystals, it has good self-sharpening, relatively neat edges, good heat dissipation,
and long service life. Therefore, ceramic alumina louvers are mainly used for
the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a
polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong
resistance to high pressure and high temperature. Therefore, zirconium corundum
louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to
decline at the beginning of grinding, and the abrasive grains are not easy to
break, so the alumina flap disc is suitable for the processing of common
metals.

Multi-channel solution to financing difficulties for SMEs
Li Yizhong said that the proportion of SMEs in China's total economic output is growing, and the State Council attaches great importance to the difficulties encountered by SMEs. At present, SMEs account for 99% of the total number of industrial and commercial enterprises, the total economic output accounts for 60% of the national GDP, the tax paid 50%, and provides 75% of urban employment. In response to the financing difficulties of SMEs, Li Yizhong said that the Opinions stipulate that local governments should be encouraged to establish SME loan risk compensation funds, while allowing private capital to enter township private banks. Township private banks and microfinance companies will become the most direct financial institutions for SME financing.
Li Yizhong also revealed that the "Opinions" clearly accelerate the development of the GEM and increase the scale of direct financing for SMEs. At the same time, steadily expand the issuance scale of short-term financing and debt financing
Encourage large and small enterprises to "crowd for warmth"
The "Opinions" propose to increase financial and tax support for small and medium-sized enterprises at all levels of finance. From January 1, 2010, the small-scale profit-making enterprises whose taxable income tax amount is less than 30,000 yuan (including 30,000 yuan) will be included in the taxable income tax by 50%, and the tax payment rate will remain unchanged at 20%. .
Li Yizhong said that many small and medium-sized enterprises are facing bottlenecks in insufficient funds for technological transformation. Therefore, the "Opinions" highlights the special funds for the technical transformation of enterprises within the central budget.
It is reported that small and medium-sized enterprises that carry out supporting production business with large enterprises will receive priority funding for technical renovation. At the same time, the state encourages small and medium-sized enterprises to enter emerging industries such as production service industries and animation software, and to form a win-win relationship with large enterprises, and encourage small and medium-sized enterprises and large enterprises to “make warmthâ€.
In view of the low proportion of SME products in government procurement, Li Yizhong emphasized that governments at all levels should increase the proportion of SME suppliers in government procurement.
"If there is no recovery of small and medium-sized enterprises, the economic recovery will not be possible; if there is no stabilization of small and medium-sized enterprises, employment will be difficult to guarantee."
“There was a guarantee company established in various places, and a re-guarantee company was established. The big bank also established the SME loan business unit. However, the financing problem has not been completely solved.†
The long-awaited "Several Opinions of the State Council on Further Promoting the Development of Small and Medium-sized Enterprises" was officially announced in the Chinese government network. Li Yizhong, Minister of the Ministry of Industry and Information Technology, who participated in the 6th China International Fair in Guangzhou, interviewed this reporter twice yesterday to interpret the "Opinions". Highlights. The reporter noted that many of the "29 opinions" are actually sending spree gifts to SMEs.
