If you want to find conveyor equipment manufacturers china,please choose Tongxiang.We supply high quality conveyor belt and conveyer roller.We have dcades of experience for good quality.Today we introduce the advantages and disadvantages of 3 belt conveyors.The industrial belt material can be divided into PVC (polyvinyl chloride), PU (polyurethane), PE (polyolefin), Si (silica gel). Here we do some analysis of the advantages and disadvantages of these conventional materials.
Advantages of PVC belt conveyor:
1. Economical, the price of the conveyor belt in the actual use of the process to take into account the cost of use, so we must consider the economy;
2. Easy processing, PVC is relatively easy to process in the processing process, good plasticity;
3. Acid and alkali resistance, polyvinyl chloride chemical stability, there is a certain resistance to weak acid and weak alkali.
Disadvantages:
1. Low hardness and no wear resistance. PVC belts have poor wear resistance during use. This is the reason why some equipments need to use PUs for selection.
2. poor oil resistance, PVC conveyor belt should not be used in food machinery and other places where edible oil or machinery oil.
Advantages of PU belt conveyor:
1. High hardness and wear resistance. The surface hardness of PU conveyor belt can reach 80-90, which has the advantages of wear resistance and cutting resistance.
2. good oil resistance, PU conveyor belt is particularly widely used in the food industry, edible oil machinery oil will not have a great impact on its service life;
3. over the roller is good, said over roller performance here refers to the use of the conveyor belt will rarely produce beating;
4. food grade, PU conveyor belt because of its characteristics in food has a very wide range of applications, pasta machinery, fried foods.
Disadvantages 1. expensive, relative to the PVC conveyor belt to talk about the price of PU conveyor belt is relatively expensive, so in the selection may take into account the cost of production;
2. weak acid and alkali resistance, relative to PVC conveyor belt to talk about PU conveyor belt is relatively weak on the acid and alkali resistance.

Advantages of PE belt conveyor:
1. food grade, this is a selling point of PE belt, it is absolutely in line with food grade, combustion produces water and CO2;
2. good resistance to pyrolysis, chemical stability, good heat resistance;
3. decomposition is non-toxic, PE is not only decomposed and non-toxic, but also relatively easy to decompose.
Disadvantages:
1. Low hardness and non-abrasiveness. PE tapes are used in the food industry and pharmaceutical industry, and should not be used in other industries.

Advantages of Si belt conveyor:
1. food grade, this feature is an important reason for its use in the food industry;
2. high temperature, silicone with conventional can withstand high temperatures of 100-500 degrees, chemically stable
3. anti-sticking, silicone with non-stick sugar, chocolate and other high sugar content foods.
Disadvantages:
1. expensive, silicone tape is relatively expensive compared to the ordinary conveyor belt;
2. the hardness is low, so that some conveyor belts in the oven are mostly used Teflon mesh belt,cloth;
3. poor roller quality, silicone tape without lateral stability, relatively soft material.
