Felt performance Wool felt application Density and types of industrial felt products, felt has the functions of filtering, polishing, sealing, liner, insulation, shockproof, oil absorption, oil protection, heat preservation, heat insulation, sound insulation and so on. Widely used in: machinery, military industry, metallurgy, mining, forestry, textile, leather, printing, electromechanical, communication, instrumentation, medical equipment, transportation, aviation, shipbuilding, electronics, electrical appliances, pianos, musical instruments, mirror and stainless steel polishing and Other plane polishing and other purposes.


         1. Felt characteristics: Felt is made of natural wool, which is machined and bonded by using the shrinkage characteristics of wool (not interwoven with warp and weft). The main features are as follows: High elasticity, can be used as shockproof, sealing, liner and material for elastic steel wire card clothing bottom felt. Good bonding performance, not easy to loose, can be punched into parts of various shapes. It has good thermal insulation performance and can be used as thermal insulation material. Tight tissue, small pores, can be used as a good filter material. It has good wear resistance and can be used as a polishing material.


         2. Application: Industrial felt is widely used in metallurgy, mine power generation, machinery manufacturing, light industry and heavy industry. Civilian felt is widely used in padding, heat preservation, heat insulation and other industries.


         3. Matters needing attention:


         1. The density unit of felt is (g/cubic centimeter). If the density is too high, the elasticity will be lost, and if the density is too small, the wear resistance will be lost. The thickness and the thickness of the hair also have different effects on its performance. The user can choose it according to the use requirements or inform the use so as not to affect the use.


         2. At present, various kinds of felts are divided into special felts and ordinary felts. The difference is divided according to the thickness, density and color of the hair; the technical requirements are divided according to the presence or absence of strength, elongation, and capillary action, and the user unit can be selected according to needs. When inspecting goods, you can use this standard to test. According to national regulations, our products can be divided into the following series for users to choose: T112112 122132 142. Four. Felt code description:


          3. The technical standard number of the felt consists of five digits. The first digit indicates the product color; the second digit indicates the raw material category; the third digit indicates the variety specification; the fourth and fifth digits indicate the product density. "T" stands for special felt. For example: T112-41 refers to special white fine felt with a density of 0.41 g/cm3. 122-32 refers to white semi-coarse felt with a density of 0.32 g/cm3. Fine white felt with a density of 0.32g/cubic centimeter to 0.44g/cubic centimeter T112-418mm×1000mm×1000mm, that is, white fine wool specialty felt blocks with a density of 0.41g/cubic centimeter, a thickness of 8mm, and a length and width Each is 1000 mm.


           Four, only need to provide, thickness and area when customizing and request. Felt wheels and felt parts can be customized according to standard requirements, and drawings and materials of felt parts can be provided at the same time. If the special type of felt products has special requirements on the technical conditions, it can be decided through negotiation between the two parties when ordering.


            5. Production of industrial wool felt: It is made of wool offal, which is made by adding chemical fibers (polypropylene fibers) and industrial adhesives by using the shrinkage characteristics of wool, and then opening, carding, webbing, and acupuncture!


            6. Types of felt products:


             1. The varieties of wool felt are: fine white industrial wool felt, medium and thick wool felt, colored wool felt, soft felt, oil-absorbing felt, chemical fiber needle felt, polishing felt, stainless steel polishing felt, sporting goods felt, thermal insulation and cold-proof felt, filter Felt, saddle felt, craft felt, blackboard eraser felt, printing pad felt, calligraphy and painting felt, musical instrument felt, felt drumsticks, insole felt, civil felt, tent felt and adhesive backed felt, and other felts for various industries.


              2. Felt accessories series; felt pads, felt strips, felt rings, felt rings, felt cylinders, felt belts, felt blocks, felt oil seals, felt gaskets, wool felt brake pads, and various special-shaped felt accessories can be produced and processed according to user requirements .


              3. Polishing series; polishing felt, wool wheel, felt wheel, glass polishing wheel, mirror polishing wheel, ceramic wool polishing wheel, stainless steel polishing wheel, polishing sheet, velcro wool ball, lace wool ball, single wool ball, double Surface wool balls can be used for polishing in various industries, etc.
