Use and maintenance of acrylic saw blades
Requirements
1. When working, the workpiece should be fixed, the profile positioning should conform to the direction of the knife, so as to avoid abnormal cutting, do not apply side pressure or curve cutting, the feed should be smooth, avoid the blade impact contact with the workpiece, resulting in saw blade damage, or workpiece Flying out, an accident occurred.
2. When working, if the sound and vibration are abnormal, the cutting surface is rough, or the odor is generated, the operation must be terminated immediately, and the fault should be checked in time to eliminate the accident to avoid accidents.
3. When starting cutting and stopping cutting, do not feed the knife too fast to avoid broken teeth and damage.
4. If cutting aluminum alloy or other metal, use a special cooling lubricant to prevent the saw blade from overheating, causing paste, and other damage, which affects the cutting quality.
5. Equipment chip flute and slag suction device ensure smooth flow to prevent slag from forming into blocks, affecting production and safety.
6. When dry cutting, please do not cut continuously for a long time, so as not to affect the service life and cutting effect of the saw blade; wet film cutting should be cut with water to prevent leakage.
Saw blade maintenance
1. If the saw blade is not used immediately, it should be laid flat or suspended by the inner hole. The other saw blades should not be stacked with other objects or feet, and should be protected against moisture and rust.
2. When the saw blade is no longer sharp and the cutting surface is rough, it must be repaired in time. Grinding does not change the original angle and destroys the dynamic balance.
3. The inner diameter correction of the saw blade, the positioning hole processing, etc. must be performed by the factory. If the processing is poor, it will affect the product use effect, and danger may occur. The hole reaming should not exceed the original hole diameter of 20mm in principle, so as not to affect the stress balance.
4. Selection of alloy grinding wheels.
1) The resin bond diamond grinding wheel has weak bonding strength, so the self-sharpening property during grinding can be good, it is not easy to block, the grinding efficiency is high, the grinding force is low, the grinding temperature is low, and the disadvantage is poor wear resistance and wear loss. Large, not suitable for heavy duty grinding.
2) Ceramic bond diamond grinding wheel has better wear resistance and bonding ability than resin binder. It has sharp cutting, high grinding efficiency, no heat and clogging, less thermal expansion, easy control precision, and has a rough grinding surface and high cost. .
3) Metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long service life, low grinding cost and high load, but poor sharpness and easy blockage.
4) Abrasive grain size has a certain influence on the clogging and cutting amount of the grinding wheel. Compared with the fine sand grain, the coarse sanding grain has a larger wear depth of the cutting edge, and the grinding wheel is easy to block.
5) The hardness of the grinding wheel has a great influence on the blockage. The high hardness of the grinding wheel is high, which is not conducive to surface heat dissipation, but it is beneficial to improve the processing precision and durability. 6) The choice of grinding wheel concentration is an important characteristic. It has a great influence on the grinding efficiency and processing cost. If the concentration is too low, the efficiency will be affected. On the contrary, the abrasive particles will fall off easily, but the optimal binder concentration range is also the best.

Cationic Dyes are a class of Basic Dyes. Dyeing speed, poor levelness, high color yield, with the retarding agent can be dyed dark.
Cationic dye affinity for acrylic big, due to the adsorption of fast and slow diffusion staining, easy to produce uneven dyeing phenomenon, and once produced uneven dyeing, dyeing difficult by extending the method to correct time. Cationic Dyes, in order to obtain uniform staining, dyeing rate should be appropriately reduced. Factors affecting the rate of cationic dyes in addition to the type of acrylic, there are temperature, pH value of the dye bath, electrolytes, retarding agent.
