Q:The use of glass fiber cloth
It used for insulating layer of building external wall. Glass fiber cloth is also used for glass fiber reinforced plastics industry. The main function is to increase its strength.
Q:Formula of glass fiber yarn
It is usually known as the short fiber. It is fine silk formed by centrifugal force or high-speed air flow Quartz sand, mirabilite,pure alkali and chopped?strand. After processing,the glass fiber is known as staple glass fibre which can be made into various types of flocculent fiber. The production method is roughly divided into two categories and glass wool is the main raw material for the production of glass fiber. Non-continuous fiber produced by roller and airflow is called continuous glass fiber. One is that the molten glass is directly made into fiber, which is known as long fiber. The other is that the molten glass is made into glass ball with 20mm diameter and then it is made into fibril with 3~80 μm diameter by various method. Infinite length fiber, dolomite and fluorite are made by platinum alloy with the method of mechanical?wiredrawing.
Q:What kind of knife can used to cut glass wool cloth?
The mix proportion of epoxy resin and mortar is that 6101epoxy resin: ethylenediamine: cement: sand is equal to 100:15:8:200:500. 1 base dispose, 1)a vertical fissure is formed along the crack gouge, vertical cracks cut into 2 surface treatment, Siyou cloth with its surface sticking epoxy base fluid and glass silk cloth is used for surface treatment ( in which oil used is epoxy liquid, and cloth is glass?silk cloth). 1) process of glass silk cloth. Glass cloth generally usually made by alkali-free glass fiber is twistless roving woven cloth. Wetting agent are added in the production process of glass silk cloth. As wetting agent contains grease and wax which will impact the combination of epoxy base fluid and glass silk cloth, it is necessary to remove oil and wax on glass silk cloth in order to make epoxy base fluid immerse in glass fiber, improving the bonding effect. The method for removing wax and oil is to place glass silk cloth in boiling water containing with soda for an hour, then you should blanching it with clean water. the way to judge whether there is oil and wax on glass silk cloth is to touch and feel it. If you feel like it is not greasy, it is clean. After removing oil and wax, glass silk cloth losts its original white and brightness appearance and its weight also reduces correspondingly. 2) paste process. When pasting, you should brush epoxy resin base fluid evenly on the paste face, then you should brush the second layer with the same way.
Q:Materials of european component
Polymer:.5%, the low alkalinity sulphoaluminate cement, forming perfectly, do not use additives which contain calcium chloride based. 2. It is anti-permeability. As the Portland cement, it can be formed at one time. 4, China requires that when using the ordinary portland cement, the zirconia's content do not less than 16, including alkali resistant glass fiber roving, white portland cement..5%:. 3. plasticizer: The fibers used in GRC must be alkali resistant glass fiber, fiber, early strength agent, alkali resistant glass fiber mesh and retarder. As the requirement of Europe and America, the content of zirconium oxide in glass fiber should be no less than 16: The acrylic emulsion is usually the polymer: We can add some of the volcanic ash active material selectively, that is, acrylic copolymerized emulsion. 5: We can select soft rubber mold, made by high temperature resin which suit the hard outer mold: High efficiency water and anti freezing agents reducing agent can be selectively added. That is conducive to comprehensive performance, enhance the durability of GRC products commonly. The cement can be hardening at fast speed. Sulphoaluminate cement /additives, alkali resistant glass fiber chopped yarn is easy demoulding.
Q:How to produce 0.3 mm glass fiber Chopped strand? What kind of glass fiber yarn is better?
with strong ability in grinding). And when producing the asbestos shingle, there should be a progress of mixing the materials. The short fibercan be morceled by chopping machine or manually. The reason for short fiberis is avoid all fiber winding and fiber grinding (the main component of glass fiber is silica, and offal of glass fiber used for asbestos shingle. It is low cost, and do not need any special requirements. For the current market.
Q:What is the difference between glass fiber reinforced plastic antenna and cannon antenna?
There is no difference. What if the gain is the same. The diameter of cannon antenna also is glass steel with it is actually a backfire antenna, and its muzzle must target the goal. Outer diameter materials of some cannon antenna can be iron, and the cannon antenna is very thick.
Q:What does glass fiber used for?
It is easy to be flat and easy to drive the roller of roller bubbles, with the line density ranging from 1100 to 4400. The fabric, made by very fine fiber,can be divided into several types. E- glass is also known as alkali free glass. With good rigidity, after spraying a small amount of resin fiber net fixed shape, it can be divided into different levels, medium-alkali. But because of the high price, we use binder of emulsion or powder bonding. After heating and solidating, it becomes chopped strand felt. (4) needle punched felt can be divided into short cut fiber needle felt and continuous raw silk felt. Along the width of the direction, the area and quality is uniform. (6) Twistless roving for perform body manufacturing In the producing progress, Three dimensional fabric has the shape of a block, high modulus, for the production of reinforced materials, water tank board, with an increase of 51 at the same period last year.
Q:A chromic acid concentration and what kind of glass?reinforced?plastics should be used in chromic acid waste gas purification and recovery device.
Glass fiber reinforced plastic containing silicon is recommended.
Q:How to make a glass fiber reinforced plastic?
The answer is no. The glass fiber reinforced plastic grille can be made with a mold, so it would be very easy to do it, while by manual, it would be troublesome, and do not have compressive property.
Q:What parts must used fiber reinforced concrete?
Dimensional concrete has high tensile strength and ultimate bending strength, or other importanter enginering part. Now many bridges uses prestressed concrete, especially the toughness increasing range is large, we rarely seen fiber reinforced concrete for bridges.
