Description

A kind of haydite aerated building block of enhancement type with germicidal action

Technical field

The present invention relates to aerated-block field, is specifically a kind of haydite aerated building block of enhancement type with germicidal action.

Background technology

The building material many employings clay brick used in building construction before China; but recent years; for the protection to soil, reduce the usage quantity of clay brick gradually, some areas prohibit the use the policy of clay brick to release and in commission.Therefore, the building material finding a kind of instead of clay vitrified brick has become the cardinal task in building trade.The a series of building materials such as Dinas brickes, hollow masonry, cement brick all have and are used under construction.Air-entrained concrete building block also along with the visual field entering people, and relies on the feature of itself to become new lover in building trade gradually.Air-entrained concrete building block has countless small, independent, the air hole structure that is evenly distributed and forms the several functions such as high-strength light, durable insulation, sound-absorbing, waterproof, antidetonation, quick construction (compared with clay brick), workability be strong, is a kind of excellent novel wall material.

Haydite is a kind of artificial light aggregate, shell is hard, inside has micro-porous ceramic saccharoid, it has good heat insulation property, has excellent fire-resistance, and surface has one deck water proof to protect the glaze layer of gas, water-intake rate is low, impervious shock resistance is good, anti-freezing property and excellent in durability, has excellent physics, chemistry and hydraulic performance.Bamboo fibers is the cellulosic fibre extracted from the bamboo of self-sow, has the performances such as good ventilation property, wear resistance, have natural antibacterial, antibacterial, except mite, deodorization and ultraviolet function.They are added in the middle of gas concrete, not only can not change the skeleton structure of gas concrete, and the performance such as intensity, bactericidal properties, anti-ultraviolet ageing of building block can be strengthened.Due to the aglite that haydite is a kind of hollow, in whipping process, because the ratio of slip is great, haydite easily floats, and causes skewness, form product defects, on the other hand, because the self-strength of haydite aggregate is lower, in whipping process, easily breakage is produced, this not only adds self water-intake rate of haydite, but also reduce product protection against the tide and weather resistance.Therefore, must process haydite, improve the producing and manufacturing technique of aerated-block.
