Several common stone disease

General senior housing decoration, the total amount of decorative stone materials 30-40%, and decorative stone can be seen in a larger share of property management, how to maintain the property in the decorative stone of its "youth often" is a property management an important task.
As we all know, anything is bound to use a certain course of time the aging rate of decline, making it obsolete, not to mention natural stone in the outdoor atmosphere by the sun, wind and rain of the physical and chemical effects, in particular environmental pollution to fading, weathering, surface uneven, more quality and construction is due to the late stone maintenance and other aspects of reason, coupled with the absence of the production process the surface care, therefore in the decorative stone buildings have been built have often visible rust, yellow, efflorescence, water spots, wet mark , stains, Bai Hua, moss and other diseases seriously affect the appearance of the stone pattern, color and luster, the decorative effect of the shade.
Decorative stone in order to eliminate the disease after processing must be carried out before the stone and decorative surface treatment, after care, to stay young, which is stone industry in the future development trend. On property management, the main decorative stone after care is now more mature and popular technology boils down to are: cleaning, care, coloring, lightening and grinding, bonding, repair, reinforcement and so on. These techniques apply to different means of pre-and post processing of stone, can achieve colorful, high gloss, durable purpose.
1 rust.
Causes are congenital and man: Some stone materials containing more carbon dioxide and pyrite, which is oxidized iron minerals exposed to air and produce rust, leaking through the porous stone. Stone in the mining, processing, installation, use of the process, especially in the process have left in the stone surface of the iron, the formation of rust after oxidation by air pollution.
The key is to prevent rust after processing in the stone surface treatment to be effective to prevent the oxidation of minerals containing iron surface after the leakage.
Property Management has been produced to deal with rust spots, mostly rust. However, due to the current market for the sale of herbicides are mostly acidic, so do not stone such as marble quality acid, dolomite should be tested before use, if necessary, diluted with water.
Also note that the rust must be thoroughly washed with water, then use the resin injected to enhance the stone water feature.
2, the wet spot water marks.
Formed mainly by the construction of the wet slurry effects. Prevent the phenomenon of wet marks quit the main stone is injected into the resin to waterproof, moisture in the air to block and stone or concrete material within the contact, reducing the chemical reaction conditions. Also, try to avoid using wet cement mortar construction, after construction adhesive seams to do with drainage.
Marks have emerged wet processing, yet there is no better way. The remedy is mainly injected into the resin wet method to mark the site does not appear to deepen the color, in order to adjust the color of the color difference between the two. In addition, penetration of stain can be used to change the color of the original decorative stone. "Wet marks quit" the disease of cancer can be stone, stone conservation is a major problem.
3, white bloom, commonly called tears.
As the wet construction, pouring cement mortar stone on the back, the rain mixed with cement mortar, dissolve the calcium or salt composition, a calcium salt composition of water filling the pores do not penetrate the stone at the real, constant, daily form oozing surface waterways, and air of acid rain and other contacts, generate insoluble white material - Bai Hua.
How to eliminate white-China phenomenon? First, stone processing, the use of permeable protective agent for six of the stone surface treatment from the nursing role; the second is the construction of the wet white cement mixed with China to prevent the agent to reduce the seepage of cement to form waterways; So maximize the use of dry linked to the construction method.
China has produced white for treatment: First, the White China part of the first wet with water, dilute hydrochloric acid and then washed until the disappearance of white-Hua; Second, rinse the cleaned stone surface to reach the neutral so far, dried , then the stone surface and joints of conservation treatment.
4, salt crystallization, commonly known as efflorescence.
Construction by the strong alkaline wet cement and the atmosphere in the reaction of the acidic solution is made.
Prevent salt crystallization phenomenon, first to avoid the wet cement mortar construction, followed by the management agent with the permeability of conservation protection. To make it waterproof.
Processing of salt crystallization has occurred, first with a brush to brush the surface of the white powder, then wash thoroughly with plenty of water residues, and finally the resin or stone into the water on the surface with a polishing agent can be polished performance.
5, lichen plant growth.
This phenomenon is mainly produced within the water and organic matter in the stone the more concentrated area, it will cause the surface to form Tailv stone, gray and yellow lichen, etc., affect the stone appearance and life.
Prevention method is to seal and waterproof. The lichen has grown used to the tools to eradicate, then a suitable cleaning agent, to be dried with the stone curing agent can handle.
