Problems solved by technology

However, in the existing similar products, the production process is complex and the requirements for raw materials are strict. Calcium oxide needs to be calcined above 1400 degrees Celsius to obtain
The production cost of the product is high and the expansion reaction time of the product is long, the construction environment is high, the temperature application range is small, the quality is unstable, and the construction time is strict. The temperature of the water added to the product in summer should be controlled below 4 degrees Celsius, and once the water is added and stirred After uniformity, the entire operation must be completed within 10 minutes, the reaction time is long, the work efficiency is low, and the phenomenon of spray holes is prone to occur

Embodiment 1

[0028] A colorless cracking agent, made of the following raw materials in parts by mass: calcium oxide: fly ash: cement clinker: water reducing agent: sodium citrate=85:8:8:0.6:0.1, pour and stir at room temperature Stir evenly in the container for 20 minutes, and finally seal the product.

[0029] When in use, add an appropriate amount of water (generally, the amount of water added accounts for 30%-38% of the total mass), and it will start to expand after 0.5 hours, and the maximum expansion pressure can reach more than 45mpa

Embodiment 2

[0031] A colorless crushing agent, consisting of the following raw materials in parts by mass: calcium oxide: fly ash: cement clinker: water reducing agent: sodium citrate=85:10:6:0.4:0.3, pour and stir at room temperature Stir evenly in the container for 20 minutes, and finally seal the product.

[0032] When in use, add an appropriate amount of water (generally, the amount of water added accounts for 30%-38% of the total mass), and it will start to expand after 1.5 hours, and the maximum expansion pressure can reach more than 45mpa.

Embodiment 3

[0034] A colorless cracking agent, consisting of the following raw materials in parts by mass: calcium oxide: fly ash: cement clinker: water reducing agent: sodium citrate=88:5:7:0.5:0.5, pour and stir at normal temperature Stir evenly in the container for 20 minutes, and finally seal the product.

[0035] When in use, add an appropriate amount of water (generally, the amount of water added accounts for 30%-38% of the total mass), and it will start to expand after 3 hours, and the maximum expansion pressure can reach more than 60mpa

Abstract

The invention discloses a soundless cracking agent and a production process thereof. The soundless cracking agent is prepared from the following raw materials by mass percent: 85 to 95 parts of calcium oxide, 2 to 10 parts of fly ash, 2 to 8 parts of cement clinker, 0.2 to 0.8 parts of water reducer and 0.1 to 0.7 parts of sodium citrate. The cracking agent has advantages of simple production technology, convenient operation, large expansibility and easily-controlled reaction time, and is not high in requirements of the raw materials and wide in temperature range.

Description

technical field [0001] The invention relates to a soundless breaking agent and a production process thereof. Background technique [0002] Crushing agent, also known as expansion agent, static cracking agent, etc., is mainly used in the mining of precious mineral materials in mines, marble, and granite, and the demolition of concrete structures such as houses, roads, bridges, and docks. But at present, wire saws are used to mine marble and granite mine blocks, which is expensive, and it is very unsafe to demolish concrete structures with loud noise, dust, and flying stones. Silent breaker is a product that can break rocks and concrete buildings without explosives without sound and vibration. Compared with the traditional crushing technology, the silent crushing technology has a high yield and has the advantages of no toxicity, no dust, no noise, no flying stones, no vibration, no pollution, safety, no impact on the surrounding environment, and convenient transportation.
