For the woodworking industry, many users high quality Acetylene pipe Not unfamiliar, this is an industrial dust collector used on woodworking carving machines, mainly used to absorb wood chips, wood ash, etc. At present, there are many kinds of woodworking vacuum tubes on the market. In the past few years, major furniture factories used PVC steel wire hoses with flat ends. In recent years, more and more enterprises have replaced cheap PVC steel wire hoses with more wear-resistant and durable pu steel wire expansion tubes. Some of the former take a few days or a month, while some of the latter take a few months or a year, They are also steel wire hoses. Why is the service life gap so far? First of all, you may have the impression that many PVC hoses have a very bad smell. This kind of hose is often used in daily life. Because the raw material itself is very cheap, the price of the finished product is also very low. For example, only a dozen yuan a piece. Think about the price of PVC raw materials, which is generally 8-15 yuan a kilogram, And most businesses will not use expensive PVC raw materials, Acetylene pipe Price The woodworking vacuum tube produced in this way has a very strong smell, not only unpleasant, but also many times the product can not even achieve environmental protection. However, the current updated product, pu steel wire telescopic tube, is a large woodworking furniture factory. An expensive woodworking carving machine uses a cheap vacuum tube with a very smelly smell, which has much to do with the overall style.

high quality Acetylene pipe 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Acetylene pipe Price It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.

Many people have never understood high quality Acetylene pipe It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Acetylene pipe Price Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.

high quality Acetylene pipe It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Acetylene pipe Price During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.

Prof. Weina, University of New South Wales, Australia? Sahajwara has developed a new method of using waste rubber and plastic for steel production - polymer injection process. Shaoxing Acetylene pipe It can not only greatly reduce the environmental pollution caused by waste rubber and waste plastics, but also effectively reduce the cost of steel production. Waste rubber and plastic contain a lot of carbon. Waste rubber and plastic are put into the electric arc furnace as substitutes for carbon element. The carbon originally locked in the waste plastic hose will react at ultra-high temperature and burn with coal to become clean fuel, thus reducing greenhouse gas emissions, At the same time, it also alleviates the environmental pollution caused by using them as landfill. The advantage of polymer injection process is that by injecting polymer and coke or anthracite rubber tube mixture, the volume of slag can be increased and the foaming degree can be increased, which can extend the arc length, increase the heat transfer from the arc to steel, reduce the heat loss through the slag and side walls, and thus improve the power efficiency. This reduces power consumption by about 3%. For every 1 ton of steel, about 24% of the cost comes from the cost of electricity. After polymer injection technology is adopted, each furnace of steel is, Acetylene pipe Price The average total amount of carbon injected can be reduced by 10%~20%. In addition, the potential price of polymer is lower than that of coke, and the total cost of carbon injection can be saved by 15%~35%.
