The choice of additive type is determined based on the type of plastic and the degree of aging. New polyolefin materials generally only add a small amount of auxiliaries such as antioxidants, UV absorbers, etc. during processing and molding. When the waste is regenerated, generally only a small amount of colorant can be added, so the formulation is not difficult to determine. Unless such plastics age severely and become hard and brittle, the composition of the ingredients needs to be determined on a case-by-case basis. The composition of PVC plastics is relatively complex, especially soft polyvinyl chloride, which contains more types of additives, including plasticizers, stabilizers, UV absorbers, lubricants, and pigments, among which plasticizers are mainly used. , The maximum amount. Its products are affected by weather conditions such as light and heat in the course of use, plasticizers gradually seep out, and the products harden, especially their physical properties are greatly reduced, gradually aging, and can not meet the use requirements and become waste products. The use of these waste products must be supplemented with sufficient amounts of plasticizers and other auxiliaries to maximize the restoration of its mechanical properties. Therefore, it is important to determine the formula reasonably. The amount of plasticizer added is mainly determined by the required hardness of the reclaimed PVC products. Therefore, the ratio of hard and soft PVC recycled products should be considered. The residual amounts of plasticizers in soft products such as polyvinyl chloride films, artificial leather, and wallpapers are not the same as those in rigid pipes and profiles. Therefore, as long as the hard and soft recycled materials are blended with each other, adjustments are made. The blending ratio of the two can produce remanufactured products with required hardness, can reduce the amount of plasticizers, and even do not use plasticizers. The general principle of the selection of additives in the furnish is to ensure that the recycled products have a certain performance, meet the requirements of use, without excessive costs. In general, the following points need to be considered: (1) Because of the low price of waste plastics and recycled products, the prices of the additives used are also cheaper. (2) Because waste plastics are often mixtures of various color wastes, dark colorants are generally added during reprocessing, so the appearance color of the selected additives is not high. (3) Additives should be able to meet certain performance requirements of recycled products. HANS was a professional diamond tools manufacturer. We have superior equipment, self-contained testing systems and strong technical capacity.Our cutting tools, grinding tools and drilling tools are widely used in the processing of stone materials, ceramics, glass, seashell, fire-retardant materials, concrete and asphalt. Through our use of technology, we are dedicated to offering you better diamond tool solutions.
These thin rim sintered diamond saw blades last longer than notched blades.The diamonds (325#/400#) are secured into a metal bond that extends the full depth of the rim. Diamonds are continuously exposed as the edge of the blade wears away cut after cut. They offer a long life and clean, thin cuts. Click to enlarge the image to see a close-up of the diamonds secured in the rim.
Precision Diamond Loop Wire Saw and Equipment in producing non-destructive, non-deforming cut or slice.Application used in cutting precious metals, plastics, quartz, glass, graphite and ceramics are just some of the many natural and synthetic materials that in Research and Development, Quality Control, Failure Analysis and Production.
Diamond Loop Wire Saw is one of the most flexible cutting tools, which can set on the surface of diamond crystals. While cutting, the diamond wire will move from one direction with the speed from 30-60 m/s. It will give users the great advantages. Widely used on cutting the rubber machine and hard surface of materials,such as,tire Section cutting machine,Tyre section cutting machine,artificial crystal (sapphire, silicon),Special Ceramic,Precious metal,graphite and plastic,brittle material. Also used on research field: geology,archaeology,architecture and biology etc. Also supply the diamond loop wire saw for tire section cutting machine.
A) 0.5-1.0mm Diameter application in artificial crystal,gem,ceramic and precious metal etc.
B) 1.0-3mm diameter application in graphite,plastic,rubber,concrete,fiberglass and foamed cement etc. Specification
1. High efficiency on cutting, while the speed from 30 to 60 m/s
2.Diameter from 0.3-3.0 mm,Length from 800-100000 mm and math for the popular machine in current market 3.Cutting fits into both wet or dry environment
4.Cutting directions could change by customer's requirement. And also could apply to cut the curved surface.
5. Operation and Replacement of diamond wire are really convention.

Economical Coutinues Rim Blades
These new blades have diamond throughout the edge and cut aggressively. blades also last a long time, because the diamond isn't just plated on top of the rim. Instead, diamond particles are incorporated into the actual metal of the rim. Cut blades up to 10" in diameter work great with water, but we advise using an additive such as Lube Cool 4800. If you use oil, these long-lasting blades will last even longer! Cut blades have a continuous rim.
Precision Sineterd Saw Blades
Precision Continuous Rim Lapidary Blade is a professional quality blade manufactured using a high concentration of premium grade industrial diamonds. These blades will cut faster than regular notched rim blades and the smaller size thin core blades can be used when cutting valuable materials to minimize loss of material. A full diamond sintered blade, The BD 303 blades can be used with rust inhibiting water coolants although oil coolants will result in longer blade life.
Notched Rim Lapidary Blade
Notched Rim Lapidary Blade are excellent quality commerical grade blades, designed for use on hard lapidary materials like agate, jasper, petrified wood, and geodes.More diamonds in the notched rim and a stiffer core make this blade cut faster and provide a long use-life. Covington Gold blades are a great low cost choice for your lapidary saw.
