Matters needing attention in stone crystallization treatment

When it comes to stone crystallization, many people are not very clear. Simply put, it is the heat generated by the friction of chemical special materials under the mechanical action, which can improve the hardness and wear resistance of stone. So, let's share the stone crystallization treatment for everyone today. In addition, we also talk about matters needing attention in the treatment of stone crystallization. Friends who want to know can come and find out, hoping to bring help to everyone.

Stone crystallization treatment

1, the rotating speed is about 154 rpm, and the weight of the machine exceeds 45 kg. Crystal hardening materials: according to the requirements of stone grinding machinery and materials, choose different crystal hardening materials, some choose black polishing and yellow polishing, some choose stone crystal hard powder, some choose stone crystal hard agent, etc. Therefore, no matter what kind of crystal hard material is chosen, we think it is understandable. No matter what material is used, the principle of crystal hard is the same.

2. For example, the chemical mechanism of marble recrystallization hardening is to soften the stone by weak acid, so that the pores of the stone are relaxed to facilitate the penetration of chemical substances, and at the same time, it reacts with calcium in the stone to form a new calcium layer after replacement, which is the crystallization effect produced by the crystallization material and crystallization construction machinery acting together on the stone surface.

3. Steel velvet: it can be divided into 0 #, 1 # ordinary steel velvet, 1 # stainless steel velvet, etc. Steel velvet should not be mixed with steel wire, impurities, rust and blackening. Polishing pad: animal hair pad, white pad and red pad. The hardness should be appropriate and the color should not fade.

4. If the ground is dirty, clean it thoroughly with universal cleaner and red cleaning pad. Mix Lishi crystal powder with clear water according to the ratio of 1: 1 and smear it on a red polishing pad. Grinding directly on the ground. Keep the ground wet during wiper operation. When high-gloss crystal faces appear on the marble surface (each brick grinds for about 5 minutes), scrape the slurry onto the next brick with a glass scraper to continue grinding. When it is found that the paste turns gray or takes a long time to shine, you can directly add a proper amount of dry crystal powder to the paste to ensure that it contains enough ingredients. When there is too much plaster, you can use a water suction machine to suck off some of it. )

5, after the completion of the project, use water suction machine to dry the ground paste. Wipe off the residue with a mop. Discharge through water. Polishing with a white polishing pad makes the ground completely clean and dry. In the crystallization process, the machine should follow the Z-shape walking and grinding.

Matters needing attention in stone crystallization treatment

1, a certain number of crystallization times is directly proportional to the brightness of the stone surface, so there should be a certain number of times, which is a process of constant hardening, brightening and glazing. Through this recrystallization hardening process, the stone can feel infiltration, and the crystal face of the stone can be maintained for a longer and more lasting time. Therefore, according to our experience, except for special stones, it is advisable for general stones to be recrystallized for 5-8 times, and it should not be less than 3 times.

2. In the process of stone recrystallization hardening treatment, the stone crystal hardener used each time is not the more the better, nor the less the better, but the right amount. Stone crystal hardener is used too much, which is not easy to polish and dry, and it is easy to produce orange peel phenomenon. The stone crystal hardener is used too little, and it will do well before polishing. The so-called golden mean is the accumulation of experience. Generally speaking, when using a new pad for grinding, the amount of stone crystal hardener is more, and it is more when grinding the ground for the first time. In the future, with the increase of times, the amount of stone crystal hardener can be reduced in turn as appropriate.

3. The use of stone crystal hardener must be carried out under clean and dry ground conditions. Of course, it is also good to use stone protectant or some special stone crystal hardener to treat wet ground.

4. Theoretically speaking, the thicker the stone crystal hardener is, the thinner the better, and the more polishing times the better. The next grinding should be carried out after the last grinding and the stone has been recrystallized, hardened and solidified, so we suggest that the recrystallization hardening treatment on the ground should not be more than twice a day, so that the ground not only has good gloss, high definition, strong permeability and good wettability, but also can greatly save the stone crystallization hardening agent.

5. Generally, after recrystallization, the whole ground stone can achieve better gloss. If it is not bright, opaque, clear and impermeable, it depends on whether your technology is correct, whether your four choices (grinding equipment, abrasive, stone crystal hardener and auxiliary materials) are correct, whether your workers operate in a standardized way, and whether the steel wool or Bai Jie pad is clean. We think that the whole stone grinding and recrystallization hardening treatment should be viewed from three dimensions (flatness, gloss and accessories).

The above is the knowledge I shared with you today about the treatment of stone crystallization. In addition, I also shared with you the relevant knowledge of matters needing attention in the treatment of stone crystallization, hoping to bring you help. In fact, Shi Jing will also be used in life, but he is not a professional and will be unfamiliar with this aspect. Then, you can learn more about this knowledge in your life, and you won't be so confused when you contact this aspect in the future.
