Problems solved by technology
With the expansion of the scope of use of acid-resistant bricks, the sharp increase in raw materials, and the increase in costs such as man-hours and transportation, it is difficult for small-scale production enterprises to maintain normal operation, and large and medium-sized production enterprises are also facing great challenges. The management strength of large enterprises, under the premise of ensuring quality, does not try to innovate to reduce material costs. Even large and medium-sized production enterprises will also face economic crisis, production enterprises will be in trouble, and even cause enterprises to go bankrupt

Embodiment 1
[0031] Embodiment 1, the described method step of producing acid-resistant brick with construction and daily-use porcelain waste powder tail powder is:
[0032] a. First, crush the collected construction and daily porcelain waste, and ball mill them into powder and pellets, mix and ball mill them in batches with ceramic polishing waste and tail powder in batches, pass through a 150-200 mesh sieve, and store them in batches as waste powder And carry out component testing in batches,
[0033] b. According to the component detection, the waste powder is divided into: first-class waste powder, SiO 2 ≥60%; secondary waste powder, SiO 2 45-60% (including 45%); tertiary waste powder, SiO 2 30-45% (including 30%);
[0034] c. The weight ratio is 10 parts of Guangdong mud, 13 parts of quartz powder, 10 parts of Banshan mud, 12 parts of Yichun kaolin, 13 parts of Jiepai mud, 7 parts of Chenzhou mud, 10 parts of low-temperature sand, 10 parts of Daling bluestone and magnesia 3 parts ...

Abstract
The invention discloses a method for preparing acid proof tiles by using waste powder and tail powder of building and daily porcelain. The method comprises the steps of firstly, collecting waste materials of the building and daily porcelain, mixing the collected waste materials, and carrying out ball-milling to prepare waste powder; carrying out component detection, and dividing the waste powder into primary waste powder, secondary waste powder and third waste powder according to the content of silicon dioxide; carrying out ball-milling on 5-15 parts by weight of Guangdong mud, 10-15 parts ofquartz powder, 5-15 parts of Banshan mud, 10-15 parts of Yichun kaolin, 10-15 parts of Jiepai mud, 5-10 parts of Chenzhou mud, 5-15 parts of low-temperature sand, 5-15 parts of Daling bluestone and 2-5 parts of magnesia mud, mixing, and sieving with a 150-200-mesh sieve so as to obtain a mixture. According to the method, the acid proof tiles, which meet acid proof tile use technical standards andcan greatly reduce raw material cost, can be produced by utilizing a great deal of defectives, waste powder and tail powder produced in a production process of the building and daily porcelain, carrying out a great deal of tests and chemical examinations, adjusting a technical formula and improving the manufacturing method.
Description
technical field [0001] The invention relates to a method for preparing industrial acid-resistant bricks, in particular to a method for preparing acid-resistant bricks from waste porcelain. Background technique [0002] Acid-resistant bricks are often used as anti-corrosion linings for towers, tanks, pools and tanks in petroleum, chemical, pharmaceutical, papermaking, smelting, power generation and electroplating industries. Its main components are silicon dioxide and alumina. It has the characteristics of pressure resistance, corrosion resistance, easy cleaning, high acid resistance, low water absorption, not easy to oxidize at room temperature, and not easy to be polluted by media. In addition to hydrofluoric acid and hot phosphoric acid, it has excellent anti-corrosion effect on acids such as warm chlorine brine, hydrochloric acid, sulfuric acid, nitric acid, and alkalis of any concentration at room temperature. And it can exert its corrosion resistance in working places ...
