Due to the limitations of technology maturity and cost control, the trend of using large base and large quantity of ordinary plastics has not changed. How to make use of the existing conditions, comprehensively utilize and save HIPS recycled materials and reduce pollution is the main way of HIPS plastics. Then, let's learn about the four methods of comprehensive utilization of HIPS recycled materials!

In recent years, the trend of global environmental protection has been gradually strengthened, and people's awareness of environmental protection has gradually increased. Located here, naturally degradable bioplastic materials are popular and demand is increasing rapidly. European and American countries and Beijing and Shanghai cities in China have also formulated various policies for the development of HIPS recycled materials. However, due to the limitations of technology maturity and cost control, the trend of large base and large quantity of ordinary plastics has not changed. How to make use of existing conditions, comprehensively utilize and save HIPS recycled materials and reduce pollution is the main way of HIPS plastics. Then, let's learn about it together.HIPS recycled materialFour ways of comprehensive utilization!

1. Making multi-functional resin glue. Waste plastics can produce multi-functional resin glue, wood board glue, printing glue. PS dissolved in benzene, other homologs or haloalkane organic solvent, can be made into a variety of coatings and adhesives. The production process is to dissolve the cleaning, crushing and drying PS foam in xylene and toluene-gasoline mixture, and add surfactant, toughening agent and film forming agent to make water emulsion coating.

2. Leak preventer. Mainly to waste plastics in the foam as raw materials, the preparation of a small amount of plasticizer, the use of hot melt technology production, plasticizing fast, fast drying, with good sealing, strong adhesion, acid and alkali, anti-aging, low cost, good effect, and good waterproof, anti-corrosion performance

3. Rust inhibitor. The embroidery anti-corrosion coating made of waste plastic has low cost and can be directly applied to the rusty steel surface. It has the functions of penetration, rust prevention and corrosion prevention. It is also suitable for civil furniture surface coatings.

4. Fueled. Because waste plastic is a material with high calorific value, it is also worthwhile to use it to make fuel. Mixed waste plastics that are difficult to wash and sort and cannot be recycled can be burned in an incinerator to recover their heat energy. It can produce solid fuel with uniform heat, or it can be liquefied into oil and then make liquid fuel for combustion. The chlorine content should be controlled below 0.4%. The general method is to crush or differentiate waste plastics and mix them to make full liquid into fuel. This fuel has the characteristics of flammability, high heat, and less ash and dirt after combustion.

China is the world's home appliance producer and consumer, in addition to meet domestic demand, there are a considerable number of home appliances sold overseas. Since the rise of China's home appliance industry in the mid-1980s, it has a history of more than 30 years. According to the calculation of the normal life span of 10 to 15 years, the household appliances produced by 2000 have reached the scrapping period. At present, hundreds of millions of household appliances are scrapped every year in our country. Most of these discarded household appliances are made of polypropylene (PP) and high impact polystyrene (HIPS) materials, of which HIPS accounts for 56%.

Contains a lot of PP,HIPS recycled materialwaste household electrical appliances not only caused environmental pollution, but also caused the ineffective accumulation of resources. The ideal method for disposal of waste containing PP and HIPS is to recycle PP and HIPS recycled materials in the waste. However, PP and HIPS recycled materials in the waste generally have problems such as aging and degradation, and their performance is obviously reduced. The recycled PP and HIPS recycled materials are difficult to reuse. Waste PP has the disadvantages of large sizing shrinkage, low hardness, anti-aging, etc., while waste HIPS recycled materials have high modulus, hardness and low shrinkage. Therefore, the waste HIPS recycled material and waste PP can be mixed to make composite materials, and the performance of waste PP and waste HIPS recycled material is complementary, but the mechanical strength of the waste HIPS/PP composite material prepared at present is low.
