Beidou satellite navigation system is a global satellite positioning and communication system developed by China. With the acceleration of the construction of Beidou navigation system, in order to promote the overall improvement of Beidou navigation product quality and ensure the safety of Beidou navigation system, the National Certification and Accreditation Administration and the General The Surveying and Mapping Navigation Bureau of the General Staff decided to jointly promote the construction of the Beidou navigation testing and certification system.
The relevant person in charge of the National Certification and Accreditation Administration said that the construction of the Beidou navigation test and certification system will be beneficial to the popularization of Beidou navigation applications, which will help improve the quality of Beidou navigation products and promote the application of Beidou navigation to international standards.
According to the arrangement of the agreement, the two parties will formulate relevant rules and regulations, support the formulation of technical standards, explore the establishment of an authorization monitoring system, plan the national quality inspection center for related products, and promote the construction, testing and certification of Beidou navigation products in key areas, key industries and important platforms. The result of the acceptance.
The National Certification and Accreditation Administration and the General Staff Survey and Mapping Bureau signed an agreement on the 3rd to jointly develop the Beidou navigation test and certification system to promote the application of Beidou navigation and international standards.
Penetrating seal Curing Agent
What is the infiltration of sealing and curing materials?
Infiltration-type sealing and curing materials (commonly known as concrete sealing hardener or chemical dust-hardener penetrant) is a new generation of lithium-ion water-based products composed of inorganic substances, chemically active substances and silicon compounds. The product is a colorless transparent liquid material, easy to use, colorless, odorless, non-toxic, non-flammable, strong penetration, can be permanently sealed concrete, VOC-free ingredients, USDA USDA test. The product, through effective penetration, undergoes complex chemical reactions with free calcium oxide components in concrete. In the three-dimensional space to form a network structure, resulting in hard material, making the concrete structure is more compact, strong, effective sealing of the pores, will never prevent concrete dust from surface porosity in the precipitation. This results in a dust-free, compact, high-strength, highly abrasion-resistant, marble-lined concrete floor. Greatly improve the impermeability of concrete, wear-resistant, freeze-thaw cycles, hardness and other performance indicators, the longer the longer the gloss the better.
Scope of application:
Permeability seal curing materials (concrete strength of C20 above the ground design requirements): the need to clean the environment, the amount of dust in the air have certain requirements, but not suitable for the surface coating material area. Applicable to any indoor and outdoor hard, highly abrasion, impermeability of the plane demanding the old and new concrete, terrazzo, cement-based wear-resistant floor and cement mortar surface, such as cement-based building materials such as factories, shopping malls, Warehouses, parking lots, service stations, hangars, freight distribution centers, roads and other areas.
Use maintenance:
1, the construction of the floor just recommended in the first 1-3 months often with acidic detergent or water to clean the ground, because often water cleaning will speed up the reaction process, making the ground seal curing effect completed in advance, the gloss will appear earlier .
2, try to avoid alkaline cleaning agents and other substances in the floor surface stay.
3, if oil, color liquid, etc. should be promptly erased, otherwise it may leave a mark on the surface.
Precautions:
1, the infiltration of sealing and curing material itself does not change the smoothness and flatness of the base surface, the old ground and low intensity whether the ground appears to be dependent on the original ground conditions may be, but the ground strength, hardness, wear resistance, gloss Such instructions will be significantly improved.
2, mechanical calendering ground, terrazzo ground and wear-resistant ground after the use of polishing will immediately appear luster, the longer the use, the better the sense of the effect.
3, low strength, dust, rough surface of the ground (wear-resistant surface floor, terrazzo floor, concrete floor), the amount of standard materials can not play a role, need to increase the amount and increase the process; but the ground conditions are extremely poor, loose structure Under the situation (turning the cement mortar floor), increase the amount may not play a corresponding role.
4, the mirror effect Floor is the highest standard floor, the original surface to be the standard requirements of the ground, a large amount of material and ultra-fine polishing process.
5, This product is non-toxic, tasteless. For non-combustible products, it should be stored in a cool and dry environment.
6, This product can only be used plastic containers, can not be used metal containers and can not touch metal objects.
7, construction curing period of 7 days, can be used during conservation period, but need to pay attention to prevent heavy impact, scratches and so on.
8, this product may not be diluted, and to prevent freezing.
9, infiltration seal curing material can be used without freezing, but the strength of the growth time should be extended; infiltration seal curing material should be used when the floor temperature is greater than 5 ℃.
10, infiltration seal curing materials, such as accidentally splashed into the eyes, apply a lot of water rinse. Store in a place not accessible to children, swallowed.
