1, mineral water bottles. Mineral water bottles are generally relatively clean, because it is transparent, there is no water can be seen, the main attention should be paid to: first check whether there is mixed with PVC bottles, estimate the content of PVC bottles, followed by see Look at the color and estimate the content of colored bottles. The closer to the transparent color, the higher the price. The closer to black, the lower the price. Look at the thickness of the bottle, because some bottles are thicker, some are thinner, and thicker bottles are The output is fast when processing, and the material to be made is beautiful. The price is high. The thin bottle yield is low and the whiteness is poor. The price is low. Then the content of other impurities is estimated.
2, milk bottles. Most of the milk bottles are made of HDPE, generally just look inside the milk is clean, because the milk bottle is not transparent, there is no clean inside is not visible, this must be carefully checked, If you have a lot of milk, it will smell bad if you put it in for a long time.
3, detergent bottles, shampoo bottles, shower gel bottles, etc. This type of bottle is more complex, different manufacturers of different materials, such bottles of material include: PET, PVC, HDPE, etc. Such bottles are generally The color is opaque, and most of the contents of the bottle are not completely emptied, so the processed material is of lower color. It is worth mentioning that the price of PET and PVC bottle is relatively low. The quality of the bottle material is generally Better, the bottle's purchasing quality is the most important, the external impurities can be seen on the surface, can be estimated. But there is no water or other impurities is difficult to see clearly, so the bottle is more difficult to purchase, it should be more Carefully check, carefully assess. Control risks.
4. Outflow material crushing material. The procurement of broken material must first look at whether the overall material is consistent, followed by looking at the quality of the material, color, and then look at the material purity, several materials should pay attention to:
1, PP, PE broken material, see. This article by the original Chinese bottle net. See PP and PE will not be mixed, check whether mixed with other plastic, you can get some into the water to see if there is no sinking , and then check what is sinking material, if sinking no other material, indicating only with filler, if there are other materials, then this material will sink it will be difficult to handle, the color will be reduced, the price is also It is reduced.
2, ABS. First look at whether there is mixed into the PS / HIPS. Mixed into the fineness is because the price of ABS mixed PS / HIPS is very different from the price of pure ABS, there is no way to separate them, the proportion of mixed The more the price is lower, the worst is 50% each, ABS is mixed to the worst of the PS, and mixing to HIPS also has a great impact on the quality of ABS. Then check whether there is any other plastic mixed into other plastics. There is no way to separate them, there is no value, and then see if there are other materials filled, mainly to add glass fiber, flame retardant materials, added will affect the quality and value of ABS. Also depends on whether the reclaim material produced by the outlet material.
3, PS, HIPS.PS/HIPS mixed problem is not big, mainly mixed into the ABS, with the ABS mixed into the PS / HIPS the same reason, they are not able to separate. View the same way to see ABS. PS and calcium carbonate The compatibility is very good, so we also need to see if it contains filler powder. The larger the proportion of filler powder, the lower the price.
4, PVC, first look at there is no mix to PC, PMMA, POM, TPU, PBT, PET, etc., the larger the proportion of plastic, because the proportion of PVC is also relatively large, if mixed is difficult to separate. PVC outlet if Mixed with PP, PE, EVA can be separated with water, mixed with ABS, PS can be separated with brine. Then see if there are other impurities and material quality, PVC can be high filled with calcium carbonate, clay, kaolin, up to 70% can be filled Above, the monthly high price with the filling amount is lower, the gloss is good, the transparency is high, the toughness is good and the quality is better. Therefore, you should look carefully at the purchase.
5, other broken materials. Other plastics such as PC, PA, POM, PBT, PPS, PPO and other engineering plastic materials. Due to the relatively small amount, there are some engineering plastics are modified, there is a certain degree of difficulty in the identification, If it is mixed with other plastics, it is also difficult to separate. Some glass fibres have low value, and it is very troublesome to mix several engineering plastics. Many mixtures cannot be separated, so the quality and purity of engineering plastic nozzles It is very important. The profit of engineering plastics is relatively high, but the risk is high. If you make mistakes in your procurement, you will lose a lot. Procurement personnel are required to undergo professional training, and unprofessional procurement personnel must be careful and must be optimistic when purchasing. Carefully assess and control risks.
Summary: The profit and risk of waste plastics coexist, and procurement is an important part of profitability. Attention must be paid to the purchase of waste plastics: quality, impurities, moisture, composites, filler content, mixes, high temperature materials, thermosetting plastics, Color, fineness. Carefully check, which can not see clearly, do not understand, do not understand the knowledge of a little bit of knowledge do not buy, there is no material sales channels do not buy, only control the risk can be invincible, only to purchase good material In order to increase profits.
2, milk bottles. Most of the milk bottles are made of HDPE, generally just look inside the milk is clean, because the milk bottle is not transparent, there is no clean inside is not visible, this must be carefully checked, If you have a lot of milk, it will smell bad if you put it in for a long time.
