Nowadays, the pollution is becoming more and more serious, and there are more and more corrosive elements in the environment. Especially for stone materials, they often appear aging, yellowing, fading and other phenomena after the baptism of time. In order to prevent this series of situations, we must do a good job in stone maintenance in advance. How to maintain stone materials? The following will introduce the characteristics of stone curing agent classification agent
At present, most of the excellent environment-friendly impregnating curing agents are based on siloxane polymer, silicon propylene copolymer or fluorosiloxane polymer, and are prepared with curing agent, catalyst and other additives. In order to increase fluidity and permeability, it is necessary to use solvent or water as a carrier to make a liquid with a solid content of 5-20% to form two series of products, solvent type and aqueous emulsion type. Since most polymer base materials are insoluble in water, the aqueous emulsion type products also need to add surfactants as dispersants. The stone treated with impregnating curing agent can be summarized into the common characteristics of quite low water absorption rate, maintaining water vapor permeability, deep penetration, long durability, no covering, no gloss, slow aging, no yellowing, no dirt adhesion, etc. through comparative tests.
In the construction process of stone (dry hanging/wet pasting), metal fasteners or cement mortar are used as the adhesive, which aggravates the pollution of stone. Therefore, curing agent is applied on the back and joints (five sides in total) of stone to form a good waterproof, breathable and acid and alkali resistant impregnating layer. After removing the floating powder of curing agent on the surface of stone, the bonding strength of cement It can also resist the erosion and pollution of cement and metal iron on stone, and effectively prevent various "stone diseases".
It has been proved by practice that in the "construction process of dry hanging/wet pasting", the stone is cured with impregnating curing agent in advance, and the effect is very obvious.
In our country, stone is widely used in a wide range of fields, and people pay great attention to the quality of stone, so it is very important for the maintenance of stone. The above is the classification and characteristics of stone curing agent introduced to you. I hope it can help you. If you have any questions about stone curing agent, please call us.
