The vast majority of basalt stones are carbonate products,and their material structure itself does not contain metallic elements.So under normal circumstances,the internal structure of basalt stone will not induce rust yellowing.There is a fundamental difference between basalt and granite.The external causes of the disease are the same,but the internal causes are different.Similar stones have the same symptoms but different causes,so the diseases are also different.
A:The reasons for the yellowing of basalt stones can be roughly as follows:
1.Pollution from colored substances,such as fruit juice,beverages,tea,pigments,dyes,etc.
2.Alkaline substance water pollution:such as grass ropes,cardboard boxes,sawdust,etc.
3.Apply protective agent before the stone is completely dry.After baking or sun exposure,the stone did not solidify,but was coated with a protective agent.Water is wrapped in stones and reacts with calcium oxide in basalt stones to calcify.
4.Basalt stones are in a damp or semi damp state,with surface waxing,polishing,or crystallization hardening.Water is sealed or crystal hardening agents undergo a slight"neutralization"reaction with basalt stones;
5.Xuanwu rock naturally turns yellow after separating from the ore body.
In light colored basalt stones,yellowing may occur accidentally;But it's not scary.Except for the fifth type of yellowing that cannot be cured,it can be avoided or concentrated before installation and does not require control.The remaining 1-4 types of yellowing are all acquired,and it is not difficult to prescribe the right medicine.Using the Italian"Fast Overlord"NOMAC,the yellowing of 1-2 level pollution can be cured by brushing or wet compress.For 3-4 types of damp yellowing,Italian Fast Ba oxidant wet compress can eliminate it.
Differential treatment of yellowing and rusting of basalt stones
B:Basalt stone rust yellow:It is pollution caused by residual metal materials on the surface of the stone being corroded and oxidized by water or acid.For this type of lesion,it is not advisable to use reagents and methods that cause basalt stones to turn yellow.To remove metal oxides,a specialized rust remover must be used.Although granite rust remover may have certain therapeutic effects,the surface of the stone is relatively corroded and the damage is difficult to repair.A few drops of Italian Fast Bar MAR covered the rust spots,and immediately replaced the rust yellow with purple.Wipe off the purple floating body,then clean it with a fine brush of oxidant,so that the rusty yellow stone is completely removed and the surface of the stone is intact and undamaged.
The above is the content that the editor introduced to you today about the different treatment of yellowing and rusting of basalt stones.Treatment should be carried out according to different lesions,and daily use should be done well.I hope today's article can be helpful to everyone.If you have any other questions about basalt stones,please feel free to contact us for consultation.
