Shanghai Dingdi CNC Equipment Co., Ltd. recommends the U.S. McDick pp board processing equipment, which is known as the pp board cutting experts, specializing in environmental protection industry, environmental protection equipment pp board material cutting, milling, engraving, perforation, slotting, opening and so on.
Maddick brand pp board processing equipment and the difference between domestic processing equipment:
Maddick brand pp board processing equipment processing efficiency, high speed, good quality. The domestic processing equipment to reach a certain processing speed, there will be a failure, thus restricting the processing efficiency of the product as well as the quality! The U.S. Maddick brand all the equipment is after strict production inspection, quality world certification, the public are very trustworthy! MDK equipment is a mechanical automation equipment, the operation is simple and easy to learn. We use the Mediatek equipment to process pp boards, only need to put the board on the table surface, and then start the computerized processing can be processed, you can process a variety of angles, a variety of curvature of the complexity of the workpiece. Because, Madick processing equipment is a processing equipment that supports CAD/CAM software, we only need to learn the drawing can be easily operated, and Madick is equipped with a flexible portable controller, simple and convenient!
PP sheet: polypropylene (PP) sheet, (PP pure sheet, modified PP sheet, reinforced PP sheet, PP welding rod)
Pure PP sheet: low density, easy to weld and process, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is the most environmentally friendly one of the engineering plastics. The main colors are white, microcomputer color, other colors can also be customized according to customer requirements. Applications: acid and alkali equipment, environmental protection equipment, wastewater, waste gas discharge equipment, washing tower, clean room, semiconductor plants and related industrial equipment, but also the manufacture of plastic tanks of choice for the material, which PP thick plate is widely used in stamping plates, press pads and so on.
Modified PP board (calcium plastic board): good dimensional stability, low price, rigidity, heat resistance and so on have some improvement over pure PP. The color is usually green, white, beige. Mainly used for water tanks, three-phase separator products.
Glass fiber reinforced PP board
Glass fiber reinforced PP board (FRPP board): 20% glass fiber through the enhancement, in addition to maintaining the original excellent performance, strength, rigidity, etc. than the PP doubled, and has good heat resistance, low temperature impact, corrosion resistance to electric arcs, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.
PP sheet is a semi-crystalline material. It is harder than PE and has a higher melting point. Since homopolymer-type PP is very brittle at temperatures above 0°C, many commercial PP materials are irregular ****polymers with 1~4% ethylene or pincushion-type ****polymers with higher rates of ethylene content. The *** polymer type of PP material has a lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has greater impact strength.The strength of PP increases with increasing ethylene content.The Vicat softening temperature of PP is 150°C. This material is more brittle due to its higher crystallinity. Due to its high crystallinity, this material has good surface stiffness and scratch resistance properties.PP does not suffer from environmental stress cracking. Typically, PP is modified by adding glass fibers, metal additives, or thermoplastic rubber.The flow rate MFR of PP ranges from 1 to 40.PP materials with low MFR have better impact characteristics but lower ductile strength. For the same MFR, the *** polymer type is stronger than the homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8 to 2.5%. And the directional uniformity of shrinkage is much better than materials such as PE-HD. Adding 30% glass additive can reduce the shrinkage to 0.7%. Both homopolymer-type and *** polymer-type PP materials have excellent resistance to moisture absorption, acid and alkali corrosion, and solubility. However, it has no resistance to aromatic hydrocarbon (e.g., benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. PP is also not oxidation-resistant at high temperatures, unlike PE.
PP board has a small density, easy to weld and processing, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is currently the most environmentally friendly requirements of one of the engineering plastics.
Applications: acid and alkali equipment, environmental protection equipment, wastewater, waste gas discharge equipment, washing tower, clean room, semiconductor plants and related industrial equipment, but also the manufacture of plastic tanks of choice for the material, which PP thick plate is widely used in stamping plates, press pads and so on.
