During the construction process on the use of yellow stone conservation agent

High-grade construction decoration materials as yellow stone, because of its noble, elegant and by consumers, but also occur in the use of a variety of issues, which make people aware of the need for conservation of yellow stone. The use of yellow stone conservation agent significantly improved after the existence of various yellow stone decoration disease is to prevent yellow stone occurrence of water spots, rust classes, Bai Hua, weathering conditions such as the most effective measures, but also to resist grease and other dirt contamination, This has been the consensus of all walks of life. yellow stone yellow stone is the curing agent can play a role in the prevention or maintenance of the product, its yellow stone is the most basic protection of water, in addition there are pollution, acid, reinforcement, and to prevent the use of yellow stone in the process due to chemical reaction corrosion of weathering on the yellow stone, and for a long time to keep the yellow stone color, the color will not make the yellow stone after use to deepen or unexpected circumstances make the use of decorative yellow stone effect is reduced, can play the role of these products can be called as yellow stone conservation agent . yellow stone curing agent is the most basic requirements waterproof, said concrete is waterproof, stain, acid, reinforcement, does not change the yellow stone color, and even some require long brightening and so on. The greatest feature of such products is the ability to breathe, that is, a single water molecule are free to enter, rather than closed, the so-called closed waterproof agent is completely airtight type is not known as the curing agent, and can only be defined as binder. High-quality yellow stone conservation agent after use should be made of yellow stone disease does not occur, to ensure the yellow stone decorative effect, in order to better protect the yellow stone, but at different temperature and humidity can play a protective role on the yellow stone, the following is simple yellow stone described the choice of curing agent product and method of operation and choice of yellow stone conservation agent notes. A selection of yellow stone products curing agent l, yellow stone curing agent product category (1), from the appearance can be divided into water-based curing agent and solvent-based curing agent; (2), from the effect on sub-divided into water, pollution , alkali, credit, hardening type; (3), from the chemical composition can be divided into inorganic silicon, organic silicon, organic fluorine and organic fluorine silicon, acrylic type (silicone and acrylic copolymer of some of the compounds, Such products can prevent some of the water without affecting the adhesive force), acrylic acid type (such products can enhance the yellow stone and cement adhesive force of the water is of little help, can assist other yellow stone curing agent to achieve a certain function) ; (4), from the effect can be divided into pure water, water-proof oil, water alkali; (5), on this basis, there is grace, quick-drying, slow drying, fast curing reaction, slow curing reaction ; (6), from the form can be divided into solid, colorless, transparent liquid, white lotion, cream, etc.; (7), a special classification (classification according to construction requirements) in dry yellow stone construction of the yellow stone on the curing agent; in wet construction of the yellow stone on yellow stone conservation agent; to prevent water spots recycled yellow stone curing agent (when used only in the yellow stone renovation); hardening: Some yellow stone curing agent in addition to water, there are hardening function, so that the yellow stone becomes hard, like the original , especially on the soft board, broken plates and powder board processing. 2, yellow stone curing agent used in the construction (1), project board class. Project board generally wool board, light board, thick panel, shaped panels, cylinder and so on. The board should not be using a variety of different yellow stone shapes and curing agent, but according to the texture of the yellow stone itself, the structure, the user’s requirements and affordability as well as the characteristics of yellow stone conservation agent may be, in order to determine the plate for that types of curing agent. (2), the use of yellow stone conservation agent after the curing time. Many people want to yellow stone curing agent used, the curing agent in the yellow stone surface faster curing, thus reducing maintenance cycle, such as the curing agent on silicate yellow stone dries quickly, and done the faster the higher the concentration, but the internal reaction to 24h to be finished. Organic fluorine type surface effect quickly drops, drops of water was also very effective, but only adhere to the yellow stone surface, once the role of external friction effects will lose water. Silicone and fluorosilicone normal type of yellow stone needs curing agent 24h before cleaning the bathroom, but there are specific, such as protective agent in the solute to do some modification, the reaction activity of the catalyst to speed up or want to add the crosslinking response speed. In theory, fast curing reaction less effective water conservation agent, the curing reaction is not as slow curing agent reaction more regular arrangement of molecules in the pores of the yellow stone surface of the internal network structure formed by more dense, and in particular the a long time. (3), the construction technology of yellow stone conservation agents used in the dry plate and the use of wet-plate construction. General conservation of yellow stone for construction are in the dry board, in case of rainy season or project time duration, some products can be not only in the dry board maintenance and construction, the board can also be wet. The use of on-site construction. Relatively slow curing reaction should be selected yellow stone curing agent, curing reaction is relatively fast because of the yellow stone surface effect may be a good curing agent, use may be more effective protective effect. yellow stone conservation should be followed by adequate time and space, so that plate dry, and wet-plate construction does not require much space, but also need plenty of maintenance time. Renovation of the yellow stone used in construction. Should be cleaned, polished, crystal noodles well prepared, choose the most appropriate agent for maintenance and construction of yellow stone conservation. The main choice of curing agent with the previous yellow stone to match. If you used the silicate curing agent, solvent-based curing agent can be used only conservation, such as silicone emulsion before the curing agent, can be used again. Such as solvent-based curing agent before, again no problem, but before the use of solvent-based curing agent, re-use of any water-based curing agent will be invalid. In addition to the construction environment not know enough or do not understand the previously used curing agent, curing agent may be selected before and after the conflict, there will deepen the color of yellow stone and other issues, or even damage the yellow stone. Therefore, the construction of the renovation of yellow stone conservation agent must be selected carefully. Second, methods of operation and yellow stone curing agent Notes 1, methods of operation: Under normal circumstances except paste curing agent, the other curing agent can be taken to soak method. Some selected volatile fast curing agent, the high cost of using immersion method can also be used according to the actual situation of the brush, wiping, spraying, rolling, splashing and other methods. 2, operation of yellow stone conservation agent should pay attention to (1), should promote the construction workers wear gloves, because the water-based curing agent in addition to silicate yellow stone other than water-based curing agents are less harmful to human skin, and solvent-based curing agent yellow stone not necessarily, such curing agent with a high active ingredient, and some even into the pores of the body after the chemical reaction, and not long out of the body, especially the poor quality of the species, the solvent is highly toxic. Such as toluene, formaldehyde, etc., can the human body can cause fatal injuries. There are irritating to the eyes, such as ethyl acetate, it is recommended not to curing agent and direct contact with skin, if necessary, do a good job protection, to protect the eyes, nose and mucous membranes. (2), yellow stone curing agent should be chosen to facilitate the construction, protection of human health, there are conservation effects and the use of curing agent and the previous match; to the use of economic, benefits, cost-effective manner for construction. Third, the choice of yellow stone conservation agent should pay attention to 1, recoatability. Because the curing agent is not any yellow stone once and for all, so consider whether re-painted and re-painted at a later time than the original effect, re-painted after the yellow stone to ensure a longer life. 2, not additive. Effect of a good yellow stone curing agent, together with other curing agents do not need to add effects, in particular, the different solutes yellow stone mixed with curing agent, does not make better conservation of yellow stone, and even counterproductive. So do not use superfluous. 3, shelf-life. Normal shelf life of yellow stone in the curing agent before packaging is not open lO months, more than lO months later, part of the curing agent will yellow stone hydrolysis, the conservation effect will decline, but they are not used, such as storage too long or exposed in the air too long, it could lead to protective performance. 4, volatile. yellow stone has a VOC content of curing agent generally, whether water or solvent-based curing agent yellow stone (other than silicate) have more or less volatile substances, in particular solvent-based, some manufacturers in pursuit of the interests of some toxic solvents (such as benzene, aldehydes, chlorinated raw materials) added, and the yellow stone on the human body is very harmful. Another is the solute carrier solvent, the solvent where the solute will be taken there. So the faster evaporation of the more shallow penetration of curing agent, the more thin protective layer, the slower the evaporation of the deeper penetration of curing agent is, the better the effect, but if evaporation is too slow may enhance the yellow stone colors. 5, corrosive. Some low-quality yellow stone curing agent have a corrosive effect on human skin, the respiratory tract may also enter the body through the body left behind after a long time can not be eliminated from the body, cause injury. 6, the pH. Taking into account the impact of yellow stone, composition yellow stone alkaline acidic curing agent is not available, the neutral components of the yellow stone with acid, alkaline curing agent can be. In addition, the yellow stone also affect the environment, such as strong at the beach alkaline, neutral curing agent is more appropriate, while acid alkaline curing agent also have an impact on the human skin. 7, the chemical reaction time. The length of curing agent reaction time, the life of the yellow stone has a great influence. Some curing agent response time is short, the effect can be immediately effective conservation; some curing agents will have some time to complete reaction. The longer the curing reaction is generally better, but can not say that the short reaction time effect on the non-conservation. 8, resistance to aging. yellow stone curing agent that can maintain long after use. No anti-aging and body can give an accurate answer can only be done through the accelerated aging test is equivalent to the reference, by artificial simulation, the general anti-250h or equal to 2 years, but this is only equivalent and not absolute only as a reference; 1000h accelerated aging resistant varieties can have 8 ~ lO years of effective protective effect, currently no more than this limit repellant. 9, the surface active agent. Coated yellow stone coated with surfactant agents on the conservation of yellow stone conservation effects are very negative impact. lO, storage and transportation. Select a product should pay attention to shelf life, shelf life is long enough, some of the packaging process in the transport of yellow stone conservation agent will be flatulence, moisture absorption and other phenomena; some yellow stone curing agent and plastic drums will be a catalyst for the reaction. 11, maintenance and construction, the curing agent in the curing reaction is not completely before not cleaning the bathroom, because excess water will make the reaction to form a mesh structure is not normal. l2, choice of yellow stone conservation agents can not only consider economic interests. Generally much cheaper product less effective, as long as the conservation of the construction side effect of keeping a few months, the project shall withdraw the matter, this approach is not conducive to the development of the industry, conservation sector should be regulated standards and services, industry to create a good environment. These are just a brief introduction to the choice of curing agent and yellow stone notes, with the use of yellow stone in the construction industry more widely, the conservation of yellow stone processing is also becoming more common, and the choice of appropriate yellow stone conservation agents will increasingly more important, should be based on the texture of the yellow stone structure itself, the user requirements, yellow stone, and the environment in which the cost of the construction process and choose the best yellow stone to curing agent. We look forward to more and better protection products to market and service the majority of yellow stone circles.
