How to protect common stone lesions?
Abstract: The key to preventing rust is to perform a useful surface treatment after the stone is processed to prevent the iron-bearing deposit from being oxidized and seeping out. 4 Salt crystallization is commonly known as efflorescence, which is formed by the strong alkaline cement in the wet construction and the acidic solution in the atmosphere. After the pores of the stone ooze out to the surface of the stone, the sodium carbonate reacts to form a salt solution. After the solution is dried, it crystallizes in the form of a crystal, which is also called efflorescence.
Stones will have some lesions after a long period of wind and rain. How can we protect these lesions?
1, rust spots. The causes of rust spots are congenital and artificial: some stone materials contain more iron, and the iron deposits are oxidized to form rust, and rust oozes through the micropores of the stone. In addition, in the process of excavation, processing, installation, and application of stone, iron remains in the surface of the stone, and it will also constitute rust pollution after being oxidized by air.
The key to preventing rust is to perform a useful surface treatment after the stone is processed to prevent the iron-bearing deposit from oxidizing and seeping out. Disposal of rust spots that have occurred in property management, first and foremost with rust removers. However, the rust removers currently sold in shopping malls are mostly acidic, so experiments should be carried out on acid-resistant stone such as marble and dolomite before use. If necessary, add water to dilute. Also note that after descaling, it must be completely cleaned with water, and then written with resin to enhance the waterproof function of the stone.
2, water spots. The primary cause of the formation of leeches is caused by the influence of cement slurry in wet construction. The sodium hydroxide contained in the cement component has a strong adsorption to moisture. In the case of traceability, it will form a corrosive sodium carbonate solution and release water. This is the wet spot and the appearance of the water spot. . The primary way to prevent the appearance of wet marks is to write the resin to make the stone waterproof, to isolate the moisture in the air from the touch of the stone or cement internal matter and reduce its chemical reaction conditions. In addition, the construction of wet cement mortar should be prevented as much as possible, and joint bonding and drainage should be done after construction.
There is currently no better way to dispose of the wet marks that are now available. The primary remedy is to use a resin writing method to deepen the color of the part where no wet marks appear, thereby adjusting the chromatic aberration between the two. In addition, you can use the soaking dye to change the tremor of the original decoration stone. "Wet marks are not dry" can be regarded as a cancer of stone lesions, which is a major problem in stone maintenance.
3, Baihua's appearance is commonly known as tears. Mostly because of wet construction, the stone is poured into the cement mortar on the opposite side, the rainwater is mixed into the cement mortar, and the calcium or salt component is dissolved in it. The moisture of the calcium and salt components enters the pores of the right material and the crevices are not solid. The long-term formation of the waterway exudates the appearance. With the touch of C02, acid rain, etc. in the air, it produces an insoluble white substance - Baihua.
How to eliminate the appearance of Baihua? First, after the stone processing, the six-sided protective treatment of the stone with the impregnated protective agent, the maintenance effect: Second, the cement white anti-agent is added in the wet construction to reduce the cement seepage Forming a waterway: The third is to use the dry hanging construction method as much as possible.
Regarding the Baihua disposal that has already occurred: First, some Baihua will be wetted with water, and then diluted with hydrochloric acid to clean Baihua until it is not seen: Second, wash the surface of the washed stone with clean water, so that the cockroach reaches the neutral stop. After the dryness, the stone exterior and joints are protected.
4 Salt crystallization is commonly known as efflorescence, which is formed by the strong alkaline cement in the wet construction and the acidic solution in the atmosphere.
After the pores of the stone ooze out to the surface of the stone, the sodium carbonate reacts to form a salt solution. After the solution is dried, it crystallizes in the form of a crystal, which is also called efflorescence. Prevent salt crystallisation. First of all, it is necessary to prevent the construction of wet cement mortar, and secondly to maintain it with a penetration preventive maintenance agent. Make it waterproof.
To dispose of the salt crystals that have already occurred, first brush off the white powder on the outside, then completely clean the residue with a lot of water, and finally finish the resin or polish it with a polishing agent with waterproof function.
5. The growth of bryophytes. The appearance of the appearance is the part of the stone where the moisture and organic matter are concentrated. It will cause the moss to form moss, gray and yellow moss, which will affect the appearance and life of the stone. The main prevention method is to stop water and waterproof. Remove the moss that has been grown and remove it with a suitable detergent. After drying, use a stone maintenance agent.
