Abrasives industry, the rapid development of the market is one to reconcile the agent to meet the customer experience to deepen changing strategies to adapt to the market.
Information released by eighteen report is not PINEZONE non woven flap wheel difficult to see, through the strengthening of environmental protection, promoting energy conservation and environmental protection, to accelerate the pace of industrial upgrading will be optimized for the national industrial development for key tasks will continue to persist. As for the abrasives industry, the upgrading and transformation will also be in line with national development, in line with industry to enhance the last word.
Abrasives industry after decades of high-speed extensive PINEZONE PSA sanding disc development, and the environment in the market left a lot of consequences. With countries to strengthen supervision of energy conservation, and gradually accelerated the pace of eliminating backward production capacity, which for the abrasives industry, will usher in a new challenge. In the recently concluded eighteen clearly pointed out the need to promote strategic adjustment of the economic structure. Promote strategic emerging industries, advanced manufacturing and healthy development, accelerate the transformation and upgrading of traditional industries. I must also mention that the PINEZONE grinding disc report was first proposed eighteen concept of "ecological civilization", environmental protection, resource conservation, energy conservation, development of renewable energy, water, air and soil pollution, and so on a range of issues included in the release the signal is strong attention to environmental protection, resource recycling, energy conservation and other related fields.

Sanding disc specific classification and characteristics
Sandpaper paper in papermaking process, because each manufacturer 's equipment and technology is not the same , resulting in paper properties are quite different , and if we do not understand the paper 's performance during use , there may be some issues not properly controlled , thus affecting the quality of sandpaper , so the correct approach is necessary to PINEZONE Mounted flap wheel master the use of paper .
First, the paper has a positive and negative difference , to the proper use of planting sand surface . A grade paper , latex paper, heavy paper and paper is generally only one belt planting sand surface , some of which are planted sand surface web , there are the web is planted outside sand surface , requiring paper manufacturers indicated at the factory . B grade paper , C grade paper according to the different requirements of coarse -grained and smoothness select different planting sand surface , medium grained on both PINEZONE cut off wheel sides can be used .
Second, the weather unstable performance of the base paper . Everyone knows can be very absorbent paper , paper is no exception , with special attention in the storage and transportation process to strengthen waterproof, moisture protection, it should be moisture-proof paper packaging at the factory and do the proof packaging that is out of the box , especially in the South and more rainy weather , more should pay attention to moisture and humid climate .
Third, the treated paper is preferably used in order to enhance water resistance and anti- glue paper penetration , do waterproof sandpaper , generally, the paper post-treatment should be used. Which is impregnated with the back-side or both sides of paper impregnated with processing , so can " plugging holes " , you can avoid a lot of glue glue into the paper , resulting in sticky sand is not strong , the impact grinding performance , but also some manufacturers of paper in the paper has been water treatment , do not reprocessed this is because the use of the paper coating or dipping method , and the resin molecules into the paper fiber , the fiber and surrounding , after the resin has cured to form a stable water- resistant , oil-resistant, preventing penetration of the solvent body structure , but the amount can not be dipping too large, otherwise it will increase the brittleness of sandpaper .
Fourth, the paper can not be processed immediately put into production because of paper when processing through high temperature baking, resulting in fiber contraction , its moisture content is also greatly reduced , prone to brittle paper , glue sand-planting immediately if carried out , will result in breaks frequently affect production, the rate of decline in genuine , serious not normal continuous production . would be better PINEZONE abrasive flap disc to store the paper treated three to five days after production ( summer hot weather should be a little longer ) , or using a humidifier process when dealing with paper, so can reduce the brittleness of the treated paper .
Five paper factory should not be used just because paper in the papermaking process, the use of a certain amount of chemical additives, these additives have a reactive curing process , commonly referred to as the paper " aging process ", generally two paper should offline after fourteen hours before use , heavy abrasive paper, latex paper , A-level paper should be kept a week after use .

To pay attention to what the problem abrasive wheel installation
First, the quality of the grinding wheel to be safe when installing detection method, Nepal velvet hammer (you can also use a pen ) tapping the side wheel , crisp sound is no problem.
Grinding machines installed in any location , is the PINEZONE abrasive sanding belt question we must first consider the installation process , only selected reasonable and appropriate location , we can carry out other tasks . Grinder prohibit installed facing or near the equipment and the operator has often been in the past where , generally larger wheel shop should set up a dedicated room . If indeed due to terrain limitations plant can not set up a dedicated wheel room, should be installed in the front wheel drive is not less than 1.8m high protective baffle and baffle requires strong and effective.
Wheel unbalance wheel mainly by manufacturing and installation inaccuracies , the rotary shaft of the grinding wheel does not coincide with the center of gravity caused . Harm imbalance mainly manifested in PINEZONE sanding roll two aspects, one in the high-speed rotating grinding wheel , causing the vibration, could easily lead to the workpiece surface polygonal oscillation marks ; hand, unbalanced spindle vibration and accelerated bearing wear , serious when will cause wheel breakage , or even cause an accident. Therefore , requiring great or greater installed directly on the card should be carried out late static balance wheel in the plastic trim or discovered after an imbalance in the work, should be repeated static equilibrium 200mm sand office .
Matching problem mainly refers to the wheel mounting chuck logistic problems . According to standards , wheel diameter not less than chuck is mounted sand office diameter of 1/ 3, and the corresponding provisions of wheel wear to a larger diameter than the diameter of 10mm chuck should be replaced with a new wheel. Thus there is a matching problem chuck and grinding wheel , otherwise it will be the case , " big horse car " wasteful equipment and materials ; " small horse cart " do not meet the safety requirements , could easily lead to accidents . Therefore, a reasonable match chuck and grinding wheel , one can save the device , cut about materials ; hand and meet the requirements for safe operation . Further, between the wheel and the installation of a larger diameter than the chuck should chuck diameter 2mm, thickness 1mm ~ 2mm upholstered .
Grinder shield is the most important protective device , its role is : When the wheel for some reason destruction at work, covering the wheel fragments can effectively ensure the safety of personnel. The shape of a circular wheel guard and square , which must not exceed the maximum opening angle of 90 °; shield material is not less than 415N/mm2 tensile strength of steel . When replacing the new wheel, protective cover installed to a solid and PINEZONE abrasive fibre disc reliable , and the guard shall not disassemble or discarded . Quiet block panel is one of the main protective accessories grinders , protective cover over the opening in the horizontal axis is greater than or equal to 30 must be set for this device ( when it 's main function is to block the grinding process of flying quiet to avoid harming operator it being attached to the open end of the shield , a width greater than the width of the grinding wheel guard , and should be firmly secured in a protective cover . Moreover , the circumferential surface of the grinding wheel requires baffle gap should be less than 6mm.
