Polished bricks are increasingly favored

Ceramics with a water absorption of less than 0.5% are called vitrified tiles. Polished tiles with a water absorption of less than 0.5% are also vitrified tiles (above 0.5% only polished tiles are not vitrified tiles), then the vitrified tiles The mirror-polished surface is a vitrified polished tile because its hardness is relatively high due to its low water absorption and it is not prone to scratches. However, because the current ceramic process is progressing very quickly, most ceramic tiles can achieve low water absorption, so vitrified tiles, vitrified polished tiles, and polished tiles on the market are actually similar products. The lower the water absorption, the better the degree of vitrification and the better the physical and chemical properties of the product.

The use of polished tiles in the process may be due to the use of improper surface contamination caused by the phenomenon of common seepage of several treatment methods are as follows:

1, tea stains, fruit stains, coffee sauce, vinegar, leather shoes and other stains use sodium hypochlorite dilution (bleaching agent), use soak for 20-30 minutes after the use of cloth to wipe; some seepage into the brick for a long time stains, soaking time It takes a few hours.

2. The mildew formed by the ink and the anti-fouling wax mold is diluted with sodium hypochlorite (bleaching agent). When used, simply wipe the bleach for a few minutes by applying it to the stain.

3, cement, scale, rust, rust using hydrochloric acid or phosphoric acid solution, rub several times.
4, paint, oil, oily marker, surface anti-fouling wax layer using alkaline cleaners or organic solvents (acetone, triethylene), paint to remove oil.

5. Decontamination by plastic hammer printing: Use a 20% to 40% sodium hydroxide (NaOH) solution to soak for 24 hours, wipe off with a cloth, and then use 30% to 50% hydrochloric acid (HCl) solution. Soak for 30 minutes and wipe with a cloth.

7, limescale acid cleaner

Remarks:

1. Use plastic gloves when using the above decontamination agent;

2, remove the stain and then clean the brick surface with clean water;

3. There are the latest decontamination detergents in the market or supermarket, refer to the above decontamination range and methods.

Chlorophyll Analyzer

Water quality chlorophyll content refers to the concentration of chlorophyll in water. Chlorophyll is a green biopigment that widely exists in plants, algae and some protists and is a key molecule in photosynthesis. The chlorophyll content in the water body can reflect the biomass in the water body and the health of the ecosystem. High chlorophyll content usually indicates eutrophication of the water body and may lead to eutrophication phenomena such as cyanobacterial blooms and hypoxia. The online chlorophyll analyzer adopts the advanced principle of fluorescence method, which can reduce the influence of stray light and has excellent repeatability and stability. RS485 digital interface, supports Modbus protocol, the Chlorophyll Sensor adopts an environmentally friendly design, with an automatic cleaning brush, and the cleaning time and interval can be set on the Chlorophyll Controller. Chlorophyll analyzers are of great significance to the protection of water environments and ecosystems. Daruifuno online chlorophyll meter is used for measuring the chlorophyll a in water, it is widely use for surface water monitoring.
