Stone inspection and analysis section

Q: what is the practical significance of stone detection for stone application?

Answer: through the detection of relevant project to stone material, can analyze and judge the physical and chemical characteristics of this kind of stone material, whether this kind of stone material can be used as building decoration material.China's stone testing is only responsible for the sample, so even if a stone testing qualified, and on behalf of this stone is all qualified, but also in the inspection link strictly control.

Two, ask: which items of stone testing are of practical value to the decoration industry?

Volume density, hardness, compressive strength, flexural strength, dry and wet state deformation, water absorption, acid and alkali resistance, weathering resistance, etc.

Three, ask: stone test we can do it?

Answer: most of us can not do, only the stone dry and wet state deformation, stone protection effect, stone protection alkali resistance and a few items of qualitative test.

Four, ask: stone analysis is what?

Answer: stone analysis is based on the stone related detection data, physical and chemical structure defect compensation possibility, mine condition, machinability and other factors to comprehensively evaluate the stone, evaluate the value and availability of stone in the application of architectural decoration.

5. Q: what is the relationship between stone analysis and decoration industry?

A: stone material analysis from the perspective of stone material application, in the physical and chemical structure of the stone itself characteristics, on the basis of testing, the stone itself defects can later compensation and the compensation cost analysis, the impact factors of gain stable bulk stone products supply mining conditions, the rate of investigation and assessment, machinability, etc.The results of the above work are of interest to the decoration industry, because the results are closely related to the building decoration industry, which is one of the biggest beneficiaries of the above research results.

Six, ask: stone dry and wet two-state deformation test is what?

Answer: it is to use detect equipment to be in dry to stone material with moist two kinds of different condition deformation quantity undertakes test.According to the size of the deformation of the stone, the deformation of the grade, for the ground stone to choose different bonding process and material to provide accurate basis.

Seven, ask: stone protective agent need to test what indicators?

Answer: bibulous rate, fight alkalescence, fight aging, permeability, fight freezing thaw sex, rebesmear sex, harmful substance content and VOC content.

Eight, ask: what is the significance of the recoating of stone protective agent?

Answer :(can be on the stone surface protection failure, protection effect decline for protection treatment or improve the protection effect of compensation treatment) first of all, the protective function of stone protective agent, in carbonated stone such as marble will be part of the loss over time.Secondly, the protective function of stone protection products will also decline because of the impact of the natural environment, such as aging.If the protective function of the stone surface is reduced, the stone should be coated with protective agent or re-protective treatment in time.At this time, such as the first brush of the protective agent does not have recoating, the compensation behind the work can not be carried out.

Nine, ask: water - based stone protection agent recoating sex?

A: No.

Q: Is it important to test the anti-alkalinity of backcoated stone protective agent?

Answer: very important, alkali resistance is not good back protection is difficult to play a protective role.

11. Ask: what is the use of water resistance test of stone protective agent?

Answer: basically it is to protect to stone material fight water pressure effect undertakes test, this is one of the important detection items that protects product to close stone material.

12. Q: what is the practical significance of aging resistance detection of stone protective agent?

Answer: it is one of items of stone material protection product important detection, it is one of the important standards that measure stone material protection product quality, also be the important factor that affects stone material protection product price.
