Definition of waste rubber Waste rubber is a kind of solid waste, and its main source is waste rubber products. Waste rubber products mainly include tires, tapes, hoses and industrial rubber products, among which waste tires are the most. In addition, waste rubber also has scraps and scrap j rubber products produced during the production of rubber products. The amount of waste rubber materials ranked second in the amount of polymer materials on the day of waste, second only to the plastics of the waste day. At present, the annual production of rubber in the world is about 20 million tons. The production of waste rubber in China has been estimated to have reached 3 million tons. Among them, the annual scrap of automobile tires in the world is more than 1.5 billion, and China is more than 120 million. The recycling of waste rubber materials is mainly based on used tires.
Types of waste rubber There are many types of waste rubber products. The types of rubber products are mainly classified into the following categories:
1.1 Tire tires are divided into tubeless tires and tube tires according to the presence or absence of inner tubes; general tires are lifted from the outside and inner tubes are composed; the rubber used in the tires is mainly natural rubber, styrene butadiene rubber, butadiene rubber and isoprene rubber; The silicone rubber is mainly natural rubber, styrene butadiene rubber and butyl rubber. Tires can be classified into automobile tires, one aircraft tires, tractor tires, motorcycle tires, bicycle tires and bicycle tires according to their use.
1. 2 tape tape is mainly divided into conveyor belt and transmission belt according to its use. The rubber used is mainly natural rubber, styrene-butadiene rubber, ethylene-propylene rubber, neoprene rubber, butadiene rubber, butyl rubber and Polyurethane rubber, etc.;
1. 3 rubber hoses are divided into cloth rubber hoses, textile hoses, winding hoses, knitting hoses and other rubber hoses. The rubbers used are mainly natural rubber, styrene butadiene rubber, neoprene rubber, butadiene rubber and chloroether rubber. Ethylene-propylene rubber, butyl rubber, silicone rubber, acrylic vinegar rubber and fluororubber.
1. 4 standard rubber shoes are divided into cloth rubber shoes and rubber surface rubber shoes. The rubber used in rubber shoes is mainly natural rubber, styrene butadiene rubber, neoprene rubber, butadiene rubber, polyurethane rubber and the like. In addition, rubber and plastic materials, thermoplastic elastomers are also used in rubber shoes:
1. 5 Industrial rubber rubber products Industrial rubber products mainly include sealing products, shock absorbing products, rubber sheets, waterproof coils, rubber rollers and other products. The second industrial rubber basically occupies all rubber materials. For example, oil-resistant sealing products mainly use butadiene rubber and acrylic.
The rubber shock absorbing products mainly use natural rubber, styrene butadiene rubber and ethylene propylene rubber; the waterproof coiled material is the main ethylene propylene rubber;
Scientific development of general-purpose rubber sheets and rubber rollers are mostly made of natural rubber, followed by styrene-butadiene rubber: the rubber materials have also undergone great changes. The second rubber-plastic blending alloy materials and thermoplastics are used in various rubber products. Many rubber products factories manufacture rubber products in order to improve product performance, improve production processes, and reduce tantalum materials or thermoplastic elastomers.
The application of these new materials, the classification, processing and utilization of old rubber has brought some new difficulties. Hong Kong Waste Recycling Company is a company specializing in the recycling of waste rubber and rubber products. It is concentrated in recycling and to a greater degree of environmental pressure.

Knitted Gloves are used for common work situations and provide basic Hand Protection.It is usually made of 100% cotton yarn or 100% polyester yarn or TC yarn.
Depending on different work protection requirement, It can be attached some material on the palm of the glove. For example: dotted PVC, PVC coating, PU coating, Nitrile coating or latex coating. It for increase the wear resistance of gloves, oil resistance, acid and alkali resistance.
