It is made of various plastic synthetic fibers as the main raw material, and is processed by weaving and heat setting. Special resin treatment is carried out as needed, and the joints of the net are also advanced. This fabric has heat resistance, abrasion resistance and high air permeability. It has obvious effects on saving energy and increasing vehicle speed. The dry mesh is highly adaptable and can be used from tissue paper to cardboard.Spiral dry mesh is made by using the latest international non-woven technology and equipment. mainly used in the dryness part of paper-making machines, drying process of printing and dyeing and other industrials.Polyester is one of the most advanced drying and filter materials in the world. The polyester spiral dry mesh produced by our company uses high-quality hydrolysis-resistant polyester monofilament, which is been formed, woven, finished and shaped.Feature1) - Polyester spiral link dryer fabric belt with high strength,good permeability,so this fabric belt is also used forhigh-pressure press-filter water,horizontal belt washer,pulp-liquor separator and mesh belt coal-washer etc.2) - This fabric belt is widely used in all kinds of industries,such as printing and dying,food,salt industry,pharmacy,environmentprotection etc.3) - Polyester spiral link dryer fabric belt is also used in papermaking industry,such as paper pulp drying,forming,and papermaking sewage treatment etc.  Polyester spiral dryer screenPolyester spiral dryer screen  can be divided into three type: 1.Small loop, suitable for fine paper .2.Midium loop, suitable for board & packing paper .3.Large loop, suitable for board & packing paper .  Features1. Long service life, wear resistance and low net consumption.2. High fatigue resistance, acid and alkali resistance.3. The  surface is flat, the tensile strength is high, the gas permeability is good, and the heat transfer efficiency is high.4. Easy to install and use, no trace on the interface, not easy to deform during use.  UseGenerally, the drying part of the paper machine adopts a double-row drying cylinder arrangement.The upper and lower dryingcylinders are equipped with a dry screen, it will presses the paper against the surface of the drying cylinder and leads the paperruns around the dryer.By using the temperature of the dryer to evaporate the moisture on the surface of the paper, and then takesthe wet air away with natural ventilation or necessary mechanical ventilation, so the paper is dried.  MaintenanceIf the paper pulp contains a large amount of waste paper, then the cleanliness of the dry web is very important. Some impuritiescan adhere to the dry web so that the ability to evaporate water is limited. Make the paper web thinner and even appears paperholes. It is recommended to clean it in time with high pressure or with professional cleaning equipment./* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
