Conveyor belt industry prospects
As the Conveyor Belt industry in China, China’s total consumption of raw rubber conveyor belt industry has been ranked first in the world, “Eleventh Five-Year” period, China conveyor belt production
Products in terms of quantity, size or level of overall technology has greatly improved, but not yet out of the extensive mode of growth, compared with the international advanced level
There are still a wide gap. To this end, China Rubber Industry Association in the development of adhesive tape industry, “second Five-Year” plan, put forward practical issues to focus on six major attack
Off. This is the correspondent October 20 tubes in China Rubber Industry Association held in 2010 with a branch hose tape information and technology to get information on the international forum.
Rubber tube with a branch of the Association in General Lee Hong-introduced, the proposed development of six topics are: straight weft diameter high-strength fabric conveyor belt, Heat Resistant Conveyor Belt, automotive flexible Ribbed, Ribbed molding vulcanization molding, steel belt brown silk with polyester and other new high-strength bone
Frame material, adhesive tape product safety PAHs in the study.
Directly by the straight weft fabric core is layered in high-strength fabric conveyor belt of new generation products, but also less layer of fabric conveyor belt of typical products
, The current domestic and foreign advanced level products are great differences should increase the conveyor belt structure, process and equipment innovation research and development efforts; with
The metallurgy, building materials industry, high temperature conveyor belt of heat-growing demand, increasingly high performance requirements, the need to further mentioning
High temperature resistant conveyor belt heat the existing high temperature level and extended service life, with particular emphasis on tape structure, reinforcing materials and plastic materials
Research; China has been able to produce a variety of automotive ribbed belt, but some need to import luxury cars with ribbed, elastic ribbed support of the automotive
Need species, and therefore the rubber temperature performance, process improvement and equipment, etc., to reach the relevant vehicle manufacturer’s corporate standards
; Ribbed molding vulcanization molding process can save raw materials, reduce waste and noise pollution, should be further compound formulation and tape structure
Research to meet the energy saving and environmental protection; polyester yarn was untwisted brown steel structure, because they do not loose and difficult to stretch, can effectively improve the transmission
Move with life and energy saving, with a skeleton belonging to the forefront of transmission technology, R & D more difficult, so should promote practical
.
In addition, the European REACH Regulation and the United States after the enactment of relevant laws and regulations, including the tape of rubber products including raised levels of polycyclic aromatic hydrocarbons
Stringent requirements, it is necessary to use our tape industry research chemicals, adhesive tape products to meet the new law related to the European Union and the United States
Regulations, which will not only help the human body, environment and ecological protection, but also conducive to tape exports.
Rubber resources to raise the level of China
This year, spurred by high prices, the country gradually increase the level of additional resources of rubber, can basically meet the consumer demand. At the same time, the dominant stocks continued to increase.
Rubber affect the price of rubber Conveyor Belt. Conveyor Belt Products: Nylon Conveyor Belt,Heat Resistant Conveyor Belt
It is estimated that the country prior to 6 months is about 2.27 million tons of additional resources of rubber than the same period last year increased about 11%. Resources constitute the main rubber, natural rubber total additional resources of about 77 million tons, up 8%; synthetic rubber is about 150 million tons, up 13%.
Natural rubber, the consecutive years of rising rubber prices, which greatly stimulated the enthusiasm for production of agricultural plastic. It is estimated that the first 6 months of cumulative production of natural rubber is about 17 million tons more than the increase over the same period last year. Synthetic rubber production has increased steadily. According to statistics, the first 5 months of total national production of 895,000 tons of synthetic rubber, up 14.2% over last year. Output of 22 million tons of them in May, up 30% compared with April, up 39% over last year.
Rubber imports increased level is down significantly. According to customs statistics, 1 to 6 months total, imports of 1.21 million tons of rubber, up 5.3% over last year, is expected to import 140 million tons of rubber in the first half or so, than the same period last year increased about 2% growth rate will fall nearly 20 percentage points .
The characteristics of rubber conveyor belt
An elastic rubber Conveyor Belt with a good, high strength, impact resistance, flexing well, into a good groove, the use of elongation, suitable for middle and long distance, high load, high-speed delivery of materials under the conditions. Rubber conveyor belts are widely used in coal, mining, port, metallurgy, electric power, chemical industry transportation of materials. The following explains the connection method of rubber Conveyor Belt:
Bonding with the first method to send the cold: the use of sticky adhesives for cold joints. This joint approach is more efficient than mechanical joints, but also more economical, should be able to have a better fitting effect, but from a practical point of view, the process conditions more difficult to master, while the quality of the adhesive joint is very large, so Not very stable.
Belts curing joint law: a proven connection is the best way to guarantee a high joint efficiency, but also very stable, the joint life expectancy is very long, easy to grasp. But there are technological problems, high cost and long connection time, drawbacks.
Should pay attention in the use of:
1, to avoid the roller covered by material, resulting in rotation not working, to prevent leakage of material between the cards in the drum and the belt, pay attention to the lubrication of conveyor belt moving parts, but not oil belt;
2. to prevent the belt load start-up;
3. conveyer belt deviation occurs, should take timely measures to correct;
4. that conveyor local damage, the application of rayon and timely repair, so as not to expand;
5. to avoid the conveyor belt being rack, post or block material block to prevent the misfortune to scratch the rip.
Heat-resistant conveyor belt and features of Notes
Heat-resistant conveyor belts often used in mining, port, electricity and other industries, in the process of using heat-resistant conveyor belt application Note: heat conveyor belt roll storage, electronic scale storage ring with a single volume, not heap pressure, folding and Cause permanent creases, generally at least once every quarter flip. Conveyor rollers, roller and roller block smooth and flexible, not rigid and fixed in contact friction. Dosing scales, electronic weighing hopper structure must be reasonable and not crushed or scratched a hard object causing the belt.
Conveyor Belt features: heat conveyor belt [1] [2] [3] is a multi-layer rubber cotton canvas (cotton cloth) or polyester canvas upper and lower temperature or heat resistant rubber coated, high temperature curing adhesive Together, for the following heat transfer 175 ℃ coke, cement, slag and hot castings. Mainly used in metallurgical, construction and other industries, transportation sinter, coke, cement clinker and other high-temperature materials, the material temperature does not exceed 800 ℃, with a surface temperature does not exceed 220 ℃ under the conditions of use. Features: EPDM rubber cover is mainly based on the loss of heat with a broken transmission capacity as well as the main performance and the different heat levels. Divided into ordinary and strong Heat Resistant Conveyor Belt, the general heat-resistant polyester canvas with a strong layer (CC56), a strong heat-resistant layer with a strong EP (also divided into type EP100, EP150 type, EP200 type, EP250, EP300 type, EP350 type, EP400 type, etc.).
