Q:The practice of acid corrosion in tank

The construction of excellent anticorrosive paint can in a variety of conditions, including exposure to atmospheric environment, can be conveniently carried out in various forms such as painting, brush painting, and meet the requirement of the design of coating thickness and structure.

Q:Chemical materials and additives needed for the production of glass

Production process of 1.3.1 glass1. Raw material pretreatment. The bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) grinding, so that dry wet raw materialsDry, iron containing raw materials for iron removal, in order to ensure the quality of glass.2, batch preparation. According to the product, the composition of the mixture is slightly different. For example, ordinary float glass batch (calculated in accordance with 1 weight boxes of 50 kilograms), need to consume 33.55 kg of quartz sand, limestone, dolomite, 2.96 kg 8.57 kg 11.39 kg of soda, Glauber's salt 0.55 kg, 3.45 kg, 0.03 kg of feldspar powder etc..3, melting. The glass mixture is heated in a bath or crucible furnace at a high temperature (1550-1600 degrees) to form a liquid glass that is uniform, free of bubbles and conforms to the molding requirements.

Q:Method for cutting thick glass

Cutting glass with abrasivesThe original A. plus sand saw diameter 95300 ~ 400mm, 1 ~ 2ram thick brass, iron plate made of circular plate, rotated, injection abrasive (silicon carbide, corundum, corundum and so on) and the slurry water mixed, with some of the side of the glass to the saw cutting force.B. with ordinary abrasive cutting compared with ordinary wheel, diamond grinding wheel, it is difficult to cut thin products, cutting losses, grinding wheel wear, wheel but cheap, especially in dry cutting, it is common to the advantages of grinding wheel cutting.C. wire cutting with multiple jointless wire (wire or piano wire = O.05 ~ 0.2mm), can also cut about 100 sheets. The edge of the abrasive material is added to the workpiece with a certain amount of pressure, and the edge is milled and cut. Because of the grinding surface cutting, the margin is very small, you can get high-precision cutting.D. abrasive jet machining method and principle of the same blast form, but the use of abrasive powder (average particle diameter of 27 m, with a tiny belly) jet nozzle (spraying gas as carbon dioxide, nitrogen and compressed air), shot edge pores, edge cut glass plate. The impact of the abrasive is so small that it will not damage the glass. This method can process thin glass plates.

Q:Yacht enterprises are purchasing their own raw materials (resin, glass fiber, carbon fiber, etc.), home composite products, accessories?

I can help you ask the business partners who are working with us on the bottom of the ship and the parts of the ship. What they do in this respect is expected to be answered by you tomorrow.

Q:What's the price of 0.85mm thick plexiglass, please?

Import plate material is better, about 900, but the price is more expensive, generally do not consider adopting, unless their own customers request, and canAt an accepted price.

Q:Aluminum alloy window material is good, how to assemble?

Glass: used for aluminum alloy doors and windows, ordinary flat glass, it is best to float process produced by flat glass. There are toughened glass, pointed glass, heat reflective glass, etc..Auxiliary material: filling material, glass cushion block, sealing material.Filling material: it is used as the backing material for filling seam. It belongs to R polymer foam, and its shape is generally round, semicircle, oval and triangle. Specifications are lOmm, 30mm and 50mm three kinds of polyethylene foam. The elongation is 50% and tensile strength is between 0.359 and 0.517MPa.

Q:The main reasons for failure of air glass are outlined

The production of hollow glass raw material quality; key factors affect the service life of hollow glass sealant is ageing resistance and desiccant adsorption capacity, and the determining factor is the performance of sealant. Because no matter how much the desiccant adsorption capacity, inside the hollow glass after a certain limit, when the hollow glass desiccant completely saturated, again good desiccant also unable to water vapor adsorption, then the hollow glass is invalid. Only when the sealant has good sealing performance, moisture permeability coefficient is low, the amount of water vapor into the hollow glass rarely, and keep this state, only rarely can guarantee the hollow glass desiccant inside gas drying, so as to ensure the effect of hollow glass. To keep the sealant unchanged for a long time, it must require the sealant has good anti-aging properties, if the material quality is not good, it will affect the life of hollow glass products, in all sealants, most can reflect is butyl rubber as the basic raw materials of various types of sealant sealant and moisture barrier properties, and so on standard hollow glass curtain wall curtain wall must adopt double sealing is a very correct decision. Here are a variety of sealants water vapor permeability coefficient table, from the table we can see that the structure of glue can not be used as insulating glass sealant alone.

Q:How do I see whether the raw material of tempered glass is made of float glass or standard glass?!

In the sun or under the light, look at the projection, float shadow is very weak, light transmission of good, lattice black lines, one by one

Q:Long plastic soft glass is a food grade raw materials?

The normal use of the family (including the dining table) is entirely without question

Q:What is the raw material of glass glue?

Glass glue is a single component elastic Acid Type RTV silicone sealant, with silicone rubber as the main raw material, adding reinforcing agent, crosslinking agent, accelerator, antioxidant, plasticizer, with advanced technology for the synthesis of one component room temperature vulcanized (RTV) sealant, resistance to atmospheric aging performance is good.
