Description
Technical field
The present invention relates to a kind of ice bank preparation methods of concrete sump bottom thermal insulation material, belong to energy-saving material technology neck
Domain.
Background technique
Ice storage technology is a kind of small investment, quick tune lotus measure, in developed countries extensive application.With
China's expanding economy, the raising of energy-saving and emission-reduction policy guidance and people's awareness of saving energy, more emphasis power-saving technology is in industry
And the application of the civilian aspect of building.
In ice storage central air-conditioning system, the device of an ice bank more than conventional Water cooled air conditioners.With regard to current project
From the point of view of, large capacity ice bank generally uses two kinds of glass reinforced plastic, concrete forms.
Glass reinforced plastic ice bank, which uses, to be spliced with the glass epoxy of pressure-bearing, unit assembled window, and construction efficiency is high, also
It can be processed with modularized production, entire construction period is shorter.And the construction of its insulating layer can be directly in external spray or laying
Insulating layer is constructed more convenient, it is not easy to generate cold bridge, heat insulation effect is good.The disadvantage is that cost is relatively high, it is narrow space can be used in
It is small, the less big occasion of scale.
Armored concrete ice bank is directly formed with concreting, is constructed more convenient, and expense cost is relatively low, is suitble to
In the applications that space is big, place is more abundant.But concrete itself needs to conserve, and construction period is longer.Meanwhile insulating layer is not
It is easy laying, especially bottom to keep the temperature, difficulty of construction is larger, and heat insulation effect is undesirable.
Actually underground be likely to bottom of pond face contact, greatly reinforced cooling capacity consumption.In addition, common brick is also direct
It is contacted with bottom of pond, and its thermal coefficient is several times as much as plastic extrusion heated board, also resulting in cooling capacity distributes, and therefore, the construction of insulating layer is
One of important link of Ice Storage Tank, quality directly affect operation of air conditioner duration and energy conservation or economic impacts.
Summary of the invention
The technical problems to be solved by the invention：For the undesirable problem of existing thermal insulation material heat insulation effect, provide
A kind of preparation method of ice bank concrete sump bottom thermal insulation material.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
（1）It takes rice husk to be fitted into Muffle furnace to calcine, washing and drying after cooling, then is crushed and sieved with 100 mesh sieve, obtain pretreatment powder
Material；
（2）Taking pretreatment powder that mass fraction is added is to be stirred at 50~60 DEG C in 20% sodium hydroxide solution, cooling
Filtering removal insoluble matter, obtains rice husk sol solutions；
（3）Diatomite is added after taking glycerine, ethylene glycol mixing, 1~2h is stirred with 600~800r/min, it is molten to add rice husk
Glue, stirring stand 2~3h, filtering, dry cool storage material；
（4）Natural sand, deionized water are taken, 1~2min of stirring in spice bucket is fitted into, adds ordinary portland cement, continue to stir
It mixes and ordinary portland cement, cool storage material, deionized water are added after 1~2min stir evenly, the concrete pavement mixed thoroughly is arrived
Ice bank bottom of pond obtains ice bank concrete sump bottom thermal insulation material after natural curing 28 days.
Step（1）The calcination temperature is 600~800 DEG C.
Step（2）The mass ratio of the pretreatment powder and sodium hydroxide solution is 1：5~1：10.
Step（3）Described weight of material part is 400~500 parts of glycerine, 500~600 parts of ethylene glycol, 200~300 parts of silicon
Diatomaceous earth, 100~200 parts of rice husk sol solutions.
Step（4）The parts by weight of raw materials be 400~500 parts of natural sands, 120~160 parts of deionized waters, 400~500 parts
Ordinary portland cement, 40~60 parts of cool storage materials.
Step（4）The number of plies of mating formation is 3~5 layers.
Step（4）The pavement process is every layer with iron roll roll-in 10~20 times, then with 0.3~0.5MPa pressure compaction.
The present invention is compared with other methods, and advantageous effects are：
Ice bank prepared by the present invention concrete sump bottom thermal insulation material replaces conventional insulation material using phase-change material, according to
Similar compatibility principle, can using its 0 DEG C of transformation temperature and latent heat of phase change using glycerine-ethylene glycol composite material as sub
It is penetrated into ice pond with blocking the heat of soil, effectively reduces the loss of ice-reserving bottom of pond portion cooling capacity, under normal temperature conditions, phase
Become the problem of material is easy flowing, it is cementing as encapsulation medium using porous material diatomite and rice husk sol solutions, it utilizes simultaneously
Phase-change material is adsorbed in diatomite than material cold-storage, is then mixed into coagulation by the inorganic salts auxiliary phase in rice husk sol solutions
In soil, phase-change material flowability problem is not only solved, concrete performance can also be improved, reaches the effect of energy conservation, section material, environmental protection
Fruit.
