Q:What is the difference between asbestos and electromagnetic fiber cotton?

Glass fiber has (no) roving and twisted to form spinning frames of different specifications and uses. There are two kinds of alkali (R2O < 0.8%, code E) and medium alkali (R2O12.0 + 0.47%, code C). Mainly used as glass steel paste, lamination, winding, injection enhancement material and the insulation, composite and fireproof glass products production molding.

Q:What is the Hongkong convention? Do you have to ship proof of asbestos free?

In order to ensure that the ship and its structure, products, equipment, systems, accessories, arrangements and materials meet the Hongkong Convention and the supporting guidelines, to guide the shipbuilding industry, shipping and manufacturing to green harmless comprehensive upgrade, and encourage new shipbuilding, ship in the premise of performance before the entry into force of the Convention, CCS has been in the "classification of sea going steel ships standard" added a "green passport" (GPR) additional signs, to provide value-added services for ships. For more details, please refer to CCS (2012), circular 113rd, number 275th. CCS the guidelines for the preparation and verification of hazardous substances in ships will be released in 2013, which contains specific requirements for implementation and requirements for the preparation and verification of hazardous substances for vessels on operating vessels.

Q:Are asbestos used in high temperature kilns harmful to the body?

Damage to my family's commitment to the use of asbestos products, the actual application is still asbestos use

Q:Standard for inspection of asbestos

test methodAsbestos testing methods are many, because the asbestos environment is different, the purpose of evaluation is different, the choice of methods are different, so there is no test can solve all the problems. Only by combining them can the validity and accuracy of the detection be guaranteed. According to the practice of asbestos inspection and reference to relevant standards at home and abroad, the main methods of combining XRD and PLM two instruments are used as the technical methods of asbestos detection in industrial products.X ray diffraction (XRD) test principle for each mineral has its specific X ray diffraction data and the intensity of the diffraction peaks of the map, and its content is proportional to the relationship, to judge whether a sample contains asbestos minerals and its content determination. This method was asbestos species, and quantitative analysis; polarizing microscope (PLM) is mainly through the observation of mineral crystal morphology, refractive index, interference color, dispersion, ductility, color, colour, cleavage, contour, projection, rough surface, Beck line characterization of asbestos minerals; XRD can detect asbestos minerals, but unable to confirm its morphology is fibrous, so you need to use PLM to confirm, through these two kinds of equipment combination analysis.

Q:Since when did asbestos brake pads be banned in our country?

The structure, performance and test methods of automotive brake systems are based on the United Nations Economic Commission for Europe (EC)(E) No. thirteenth regulations on the unified provisions on motor vehicle braking of M, N and O, ISO7634- 1995 "test methods for air brake system of towed vehicles", "ISO7635 - 1991" roadThe vehicle brake pressure, gas-liquid test method "," ISO65971991 road vehicles hydraulic system"Performance test methods for mobile systems" and other standards and regulations for GB / T12676 - 90 "automotive brake performance road""Road test method" revised. This standard applies to the brake system of class M, class N vehicles and class O trailersNational mandatory standards.Wang Yao said, in less than three years, to achieve brake pads without asbestos, brake pad manufacturers feelThere has been a great deal of pressure. At present, many enterprises are either fast or slow, or more or less asbestos free productsDevelopment, the country's 300 major production enterprises, most of them have their own asbestos free formula, and some have formed aFixed size, and a batch of products exported to Europe and America market. Even so, Wang Yao still reminds us, brake disc production enterprisesIndustry must pay more attention to the situation than before, understand the market dynamics, and be in the product development and sales market during the transition periodField work in order to smooth integration into the "no asbestos" market.

Q:The difference between asbestos and aluminium silicate

Asbestos is usually light yellow, while aluminum silicate is white. Aluminum silicate soft cotton. The aluminium silicate cotton has better fire resistance than asbestos, and is suitable for high temperature heat insulation; asbestos is mainly used for fire protection and heat preservation.

Q:Are asbestos natural or artificial?

Asbestos is a natural, fibrous, silicic mineral. It comes from natural minerals and is processed in a physical manner.Asbestos is not synthetic material.

Q:Which is good, brick, asbestos or pure cotton? What are the advantages and disadvantages?

Diamond cotton is polyester fiber (chemical fiber product). Pure cotton is cotton fabric (two kinds of natural and renewable). Bedding recommended, pure cotton, comfortable.

Q:Why asbestos is banned as building material?

[asbestos] refers to silicate mineral products with high tensile strength, high flexibility, chemical and thermal resistance, electrical insulation, and spinnability. It is a general term for natural fibrous silicate minerals. Under the jurisdiction of the 2 class a total of 6 kinds of minerals (with serpentine asbestos, amphibole asbestos, asbestos, actinolite anthophyllite tremolite asbestos asbestos, iron, etc.).

Q:Is asbestos net stone or cotton?What else is the use of asbestos nets besides chemistry?

Color color asbestos asbestos and asbestos and complex material has been put into production in 1970s, Thailand has more than ten years of history, five years of production in Russia, Guangzhou, recently in Beijing, Kunming, Fujian and other places have also launched a variety of color, asbestos board. The product has broken the traditional products a single pattern not only in appearance, more important is the curing of asbestos fiber and dust completely, to a good role to avoid environmental pollution etc.
