A kind of have the high-strength ceramic brick and production method thereof that regulate humidity function
Technical field
The invention belongs to the preparation field of architectural pottery product, be specifically related to a kind of high-strength ceramic brick and the production method thereof with adjustment humidity function.
Background technology
Relative air humidity is the physical quantity representing the how many that is dry wet degree of water in air vapour, it is the important parameter weighing indoor environment, it is all significant to depositing of HUMAN HEALTH, IAQ (indoor air quality) and article, too high or too low humidity effect HUMAN HEALTH, has serious hazardness to the preservation of article, the life-span of instrument etc.; Harm when humidity is alternately changed by too high (low) to too low (height) is even more serious.Country's " air quality standard " specifies indoor relative humidity standard value, and summer air-conditioning room is 40% ~ 60%, and winter heating room is 30% ~ 60%.China's humid area annual relative humidity is 70% ~ 80%, and sometimes up to 95% ~ 100%, the relative humidity of northern drying period even can reach less than 10%.The building in these areas will reach the thermal comfort requirement of indoor environment, the indoor environmental quality problem brought with regard to needing to take efficient method to solve relative humidity.At present, humid control control method can be divided into proactive and passive type method by whether consuming artificial energy source.The former i.e. air-conditioning technical, is 20 methods generally adopted at present, consumes a large amount of electric energy, and contaminate environment and destruction ecology, cause problems such as " architecture indoor syndromess ", do not meet the strategy of sustainable development.The latter utilizes the moisture adsorption and releasing characteristic of renewable energy source or material to carry out regulating and controlling humidity, without the need to consuming any artificial energy source, is a kind of ecological property regulating and controlling method." humidity adjusting material ", refers to and does not need, by any artificial energy source and mechanical means, to rely on the moisture absorption and desorption property of self, and induction institute adjusts the change of space empty gas epidemic disaster, thus the material of automatic adjustment relative air humidity.Japan, during 1980 to 1987, employs humidity adjusting material greatly in nearly hundred engineerings, plays a significantly greater role with keeping to the protection of historical relic and important fine arts books and periodicals.The humidity adjusting material research patent of Japan was in the trend risen in recent years, mainly
It is inorganic humidity adjusting material.Before the state-run industry comprehensive technology research institute of Japan, Tian Yaxi is by water glass and aluminium hydroxide and kaolin through 800 DEG C ~ 1150 DEG C common sinter moldings, makes the aluminium base humidity adjusting material with humidity adjusting function; JANIS company utilizes one or more and mineral binder bond of sepiolite, diatomite, zeolite and light weight concrete to be raw material, makes humidity control material through shaping and drying.
The domestic research for humidity adjusting material, majority selects the materials such as zeolite, diatomite, malthacite, glassiness volcanic soil, sepiolite, acidic white earth, gac, silica gel, white carbon black, activated alumina, aluminium hydroxide as main absorbent, the moisture absorption and desorption property of natural mineral is utilized to reach damping object, but performance in damping capacity, damping responsiveness etc. or not ideal.
At present on the market for for the research of passive type green hue wet stock and product all not yet ripe.Although organic humidity controlling material moisture uptake is large, rate of moisture absorption is fast, and moisture releasing amount is little, and moisture releasing speed is slow; The mineral such as polynite, diatomite, sepiolite have natural porous and laminate structure, and as moisture regulator, wet volume capacity is less; Although some novel humidity adjusting material humidity is better, manufacturing process is complicated, and production cost is too high.Therefore, this technology need to improve.
