Water Permeable Bricks - Rechsand

The surface of the insomnia brick is very dense, belonging to the high-end micron-level water.

Yan Chuang permeable brick permeable speed is more than 20 times the industry standard.

Advantages of benevolence:

(1) Permeable speed: Ren Chong permeable water brick is very fast, can be achieved (780kg per hour per square meter of water). Renzheng tiles experienced Beijing 721 heavy rain test (60 years a case), 721 during the rainstorm, laying benevolent water permeable bricks of the Olympic underground square without any water.

(2) Permeability Long: long penetration of the water permeable brick is the principle of “damaging the surface tension of the water”, the surface of the brick is very dense, it is not easy to be blocked by dust, the duration of the permeable period is more than 30 years!

(3) Anti-clogging: benevolent permeable water permeable principle is “damage to the surface tension of water”, the brick surface is very dense, micron-level water, and very easy to clean.

(4) Anti-freeze-thaw: A brick body capillary, small, water into a small volume of ice, high dispersion, expansion is small, so the brick is not easy to be frozen

B. Add a special binder, so that brick toughness is good.

C. Brick within the capillary evenly distributed, a single pore diameter is small, no stress concentration.

(5) Anti-stress: Ren Chong water brick can withstand less than 100 tons of weight

(6) Super wear-resistant: brick main raw material for the wind sand, is after millions of years, the wind sand and the formation of hard points, made by a special process, grinding wheel-like wear resistance.

(7) With a filter function: benevolent water permeable brick in the water at the same time with the role of water can be large particles of rain impurities in the brick body outside the filter.

Oil Production Cases - Rechsand

Ren Chong Fu Sheng sand used in the oil and Sinopec oil field

Customer evaluation: Since the use of oil duo duo, I no longer have to worry about the exploitation of oil it!

Case story:

A new generation of fracturing proppant “Fu Sheng sand” (FSS), by the Beijing Science and Technology Group, a research and production, sandstorm sand as raw material sand core, select a special polymer as a reinforcing agent, through the reactive coating Technology, so that the outer surface of quartz sand coated with a layer of polymer film made.

This product through the quartz sand of the technological transformation, making it has a relatively small density, low broken rate, good chemical inertness and so on.

The product has been widely used in oil fracturing construction, which can effectively improve the sand ratio, to achieve uniform cloth sand, reduce the requirements of fracturing fluid, with long to maintain high fracture capacity, to extend the validity of fracturing, improve oil recovery and other characteristics.

The The product in the oil industry, “oil impermeable” Fu Sheng sand can significantly increase crude oil production, improve oil quality, has been Jilin Oilfield, Daqing Oilfield, Yanchang Oilfield, Changqing Oilfield, Zhongyuan Oilfield, North China Oilfield, East China Oilfield, PetroChina, Sinopec and other large oil extraction, refining enterprises to use.

Breathable flower pots: 

Sand flower pots in the breath at the same time can lock the water and nutrients, why say so? Because the bottom of the pot will breathe no openings. Water and nutrient flow does not go out, so you can do water, fertilizer, health effects.

Classification of Permeable Bricks - Grassy Pavers 

(on Wattpad) https://www.wattpad.com/734142026-classification-of-permeable-bricks-grassy-pavers  

From the point of view of the classification of permeable bricks, according to the principle of water can be divided into two categories, one is to rely on the surface of the brick hole through the water, one is in accordance with the gap between brick and brick through the water. The later type is more common.

Precision Casting Corporation — Rechsand

Coated sand as the raw material in the desert, processed into a new type of precision casting material coated sand, a green precision casting of key technology products, the upgrading of traditional casting materials to fill an international casting industry blank, won the Ministry of Electrical and Mechanical Science and Technology Progress Award, and in the country to create the first fully automatic coated sand production line, to achieve “sand casting.”

In the precision casting industry, the automobile industry more than 90% of domestic brands, some joint ventures and foreign brands are using “Ren Chong covered sand” series of products, such as the North Benz, Shanghai Volkswagen and other enterprises.

Features: Fast Curing, High Strength, Low Gas, Low Expansion

Advantages: to adjust the speed of gas, better to avoid the casting hole defects

Product Price: contact the website immediately to obtain the latest offer!

Industry status: China’s auto engine parts more than 90%, are made using Ren Chong coated sand made of.

Ren Chong covered the story of the birth of film

At that time the industry background:

In the foundry industry, the manufacture of many precision instruments, the need to do with the mold to do the sand, such as the car’s engine. But not all sand can be competent, then has been relying on imports from Australia, the British sand, the price of this imported sand a ton of up to 7,000 yuan.

Qin Shengyi initiation idea:

Young and fit Qin Shengyi decided to develop mold to do the domestic sand. In 1985, he first proposed with China’s Inner Mongolia desert 10 yuan a ton of blooming quartz sand, instead of imported zircon sand to do precision casting materials. This idea is ushered in a cynical. The reason is that the expansion of quartz sand is three times the zircon sand, easy to deformation after heating, it is impossible to replace the zircon sand. Even the then developed US technology is also the use of imported zircon sand.
