The difference between the new seamless terrazzo and the traditional terrazzo
Edit:Guangdong Meifule New Material Technology Co., Ltd.   PublicDate:2019-03-25

First, the advantages of Jincheng seamless terrazzo:

(1) After the surface light is brightened, the high brightness reaches 70~90 degrees, and the dustproof and anti-skid reach the marble quality;

(2) good wear resistance, surface hardness can reach 6-8;

(3) The existing or prefabricated terrazzo, freely spliced colors and colors can be customized;

(4) The new terrazzo is not afraid of heavy truck rolling, not afraid of heavy objects dragging and not shrinking deformation;

(5) It has no dust and high cleanliness; the cleanliness meets the requirements of high clean environment such as pharmaceutical and chip manufacturing;

(6) Inorganic materials, non-combustible, anti-aging, anti-fouling, anti-corrosion, no odor, no pollution;

(7) The existing terrazzo decorative grids are horizontal and vertical, no gaps are required between the grids, the connection is dense, and the overall appearance is good; the commercial terrazzo can be designed freely to achieve beautiful decorative effect.

Second, the difference between traditional terrazzo and Jincheng new terrazzo

1. The material used different traditional terrazzo using ordinary Portland cement as the cementing material, the hydration product is hydrated calcium silicate; the modern grinding stone is made of silicate, aluminate and calcium sulfate (gypsum). The material, the hydration product is a mixture of calcium vanadium and calcium aluminate and calcium silicate. Compared with the traditional cement grindstone, the new polymer modified cement grindstone has a series of performance advantages such as early strength, fast hardening, quick drying, large seamless assembling area and diverse aggregate selection.

2. Difference in aggregate selection

Conventional cement grindstones have strict control requirements on the type and particle size of aggregates. Generally, aggregates with a particle size of 4-8 mm or more can be selected for low-absorbent aggregates (such as glass, quartz, porcelain, etc.). Poor compatibility. The reason is that the hardness of the hydration product of Portland cement is low, that is, the "grip force" is poor. The small particle aggregate is easy to "jump the sand" during the grinding process, and the low water absorption aggregate cannot be effectively bonded. It greatly affects the surface decoration effect; while the polymer modified cement grindstone has a reasonable aggregate grading, it is very good for the "grip force" of 1-3 mm or even finer aggregate, it is not easy to jump sand, and it can also be added low. Absorbent aggregate.

3. Difference in construction speed

After the traditional terrazzo paving, it needs the same curing time as the concrete. After at least 10 days, the surface grinding can be carried out. The modern grinding stone is quick-drying and early-strength technology, and it can be polished in 24 hours (the compressive strength is basically above 25MP, the standard temperature environment Under conditions).
