Q:How many specifications of glass fiber?
According to fiber diameter, there are many varieties and specifications and spun yarn is used for industry and electron in term of application. There are many specifications including E series, G series, D series and H series.
Q:What are the characteristics of grc material?
Q:What is electroplate glass fiber cloth?
Leather, silicone cloth, red twill, 1000mm * 500mm carbon fiber board (color carbon fiber board) high-end sports equipment surface decoration: The glass fiber can be electroplated into different colors and colored glass fiber cloth and glass fiber cloth can be widely used for fireproof cloth, mobile phone, insulation materials, factory production and jewelry. Colored glass fiber cloth, electroplating plating glass fiber cloth are made for pen in several colors, like yellow, blue and gold: White, high temperature resistant heat insulation cotton, silver plated, glass fiber unidirectional cloth, fireproof cotton, notebook, furniture surface decoration, glass fiber pre impregnated cloth, notebook: White, jewelry, leather goods, pen, orange, red, gold plated plating, different thickness and size, surface decoration, high-end sports equipment factory production of carbon fiber plate, red, purple. 2. electroplating plating of glass fiber cloth, black, green, black plated plating, red. 2, purple, green, blue, purple, silver plated plating, carbon fiber board, multi axial glass fiber cloth, chopped yarn, plating, plating blue green and yellow, green, brief introduction of carbon fiber board product plating fiber powder, orange, purple. Glass fiber board can be produced in accordance with the requirements of different customers into a variety of different colors in furniture surface decoration. Plated orange
Q:Epoxy resin mortar mix ratio
200 to 300 of mortar and 100 of epoxy resin will be fine. It should be added according to concentration. Construction convenient and high quality can be reported as the premise.
Q:What kind of knife can used to cut glass wool cloth?
You just need to cut off the big square. At first, you need to cut off the big square along border line and center line. Then you should cut off the two overlapping rectangles along the diagonal. At this moment, there are four right triangle which just can be put into a hollow square with its area just is equal to the small square, then you should put the small square into the hollow aquare.
Q:Introduction of inorganic glass fiber reinforced plastic air pipe
Inorganic glass fiber reinforced plastic air pipe, according to the properties of the binding materials, can be divides into: Made of binding materials with glass fiber mesh cloth hydraulicity inorganic glass steel duct and made of cementitious materials and glass fiber mesh air hardening modified magnesium oxychloride cement duct with two types of modified magnesium oxychloride cement to the sulfate type. The pH value of the hardened material should be less than 8.8, and there is no alkalinity corrosion of the glass fiber. Inorganic glass steel duct should be used alkali-free, medium alkali or alkali resistant glass fiber mesh cloth, and are consistent with current national standard "glass fiber grid" JC561, "the alkali free glass fiber roving," JC/T281, "in the alkali glass fiber roving" JC/T576 regulations. The quality of magnesium oxychloride cement duct Magnesium Oxide should comply with the national standard "Magnesium Oxide" light burned magnesite products with WB/T1019-2002 regulations. Inorganic glass steel duct can divided into the overall common type (non insulation), integral insulation type (inner and outer surface of inorganic glass steel, middle insulating material) and combination type (by special adhesive, composite plate, flange, reinforcement angle etc) and the combination of insulation, its production parameters should comply with the provisions of the table 1, 2, 3. The longitudinal and transverse lap joint distance between adjacent layers of glass fiber grid cloth should be more than 300mm, and the distance of the same layer lap joint shall not be less than 500mm. Lap length should be greater than 50mm. The wind pipe surface thickness of the slurry flating glass fiber mesh cloth is appropriate. And the surface do not have dense pores and spillage.
Q:A chromic acid concentration and what kind of glass reinforced plastics should be used in chromic acid waste gas purification and recovery device.
Rated condition is 2. * filtering grid should be cleaned regularly according to the degree of pollution. * according to different air volume. There are two types including vertical network format and horizontal network format. * Airflow direction of horizontal recycle collector is from right into the left, and chromic acid waste gas purification recoverer is mainly used for recycling and purifying chromic acid waste gas from electroplate chromate tank belt. * the bottom must be maintained at a level of 5 meters. *Face velocity passed through recoverer filter net must be maintained at 2 to 3 meters per second so that chromic acid can be expelled from bottom hole with efficency is over 90% and chromic acid liquid is recycled. * All air duct system before the recoverer is made from plastic plate. The chromic acid can be directly poured into the plating bath with the airflow direction cannot be reversed. The airflow direction of vertical collector is from bottom to top and it should be used together with BF4-72 type centrifugal ventilation machine. It can be cleaned once a month.
Q:how to produce glass reinforced plastics grating
You can dip winding roving into resin and demould it after curing, then geogrids mould is formed.
Q:The difference between glass fiber plain cloth and glass fiber woven roving.
According to the weight and width, there are many models including 200 g, 400 g, 600 g and 800 g. The width of 900, 1000, 1270 and 1400 are commonly used. The width is from a few centimeters to 3 meters and the weight is from 60 to 800.
Q:grc fiberglass
the content of ZrO2 in alkali resistant glass fibre whcih was used as reinforced material for portland cement is not less than 16. According to specific provisions in the T841, it is clearly required that alkali-resistant glass fiber must be used in GRC with its type incledes twistless roving.
