Description of drawings
Fig. 1 is the schema of the production method of a kind of water glass of the present invention;
Fig. 2 is the skeleton diagram of the production system of a kind of water glass of the present invention.
Embodiment
Generally speaking, water glass project construction technical process is to deliver to the storehouse that feeds intake after raw material quartz sand and soda ash proportioning stirring according to a certain percentage, evenly drop in Reaktionsofen (feedstock direction is consistent with direction of heat flow) under reciprocating type batch charger effect, material at high temperature molten state react generate water glass after, from the positive discharging of stove, inject the cooling rear output products of piece material machine, the sale of dispatching from the factory after packing, checking.
See also Fig. 1, the invention discloses a kind of production method of water glass, comprising:
S1. with quartz sand and soda ash according to weight ratio be: the ratio proportioning of 1:1 stirs, and forms mixture;
S2. described mixture is evenly delivered to kiln;
S3. in temperature was the scope of 1400 ℃～1500 ℃, described mixture generated water glass and CO
2
Reaction principle is that raw material quartz sand and soda ash react under the high temperature of 1450 ℃ of left and right after proportioning by a certain percentage and generates water glass and carbonic acid gas, and formula is as follows:
SiO2+Na2CO3—>Na2SiO3+CO2
S4. described water glass is chilled to 650 ℃～750 ℃, can obtains finished product.
See also the production system 1 of Fig. 2, a kind of water glass, the storehouse 100 that feeds intake that comprises the mixture of placing quartz sand and soda ash, generate the kiln 200 of water glass and CO2 in temperature is the scope of 1400 ℃～1500 ℃ with storehouse 100 delivery ports that feed intake being used for of being tightly connected, is connected with kiln 200 delivery ports for described water glass is chilled to the piece material machine 300 of 650 ℃～750 ℃.
