Description
Technical field
The present invention relates to the preparing technical field of coal adhesive, be specifically related to a kind of tackiness agent that improves the Filter Tuber For Clean Coal cold strength and preparation method thereof.
Background technology
The Filter Tuber For Clean Coal tackiness agent, also claim briquette binder, briquette adhesive, composite adhesive for briquette etc., is by the pulverized fuels such as coal dust bonding, reinforces together, is beneficial to the blender of moulding, and it is mainly used in the coal briquette complete processing, plays booster action.The coal briquette tackiness agent is the crucial auxiliary material that determines the briquetting quality.To there is certain cold strength through the moulded coal (ball, rod) of bonding, moulding, oven dry entering stokehold.The cold strength of moulded coal, except meeting the unlikely destruction of general transportation, also has direct relation to entering the load of coal briquette thickness weight after stove.The general industry gas furnace the burning gas-making process in, coal as raw material in stove roughly as three layers of motion: orlop is zone of combustion, and centre is the layer of getting angry, the top be bed of cloth.In gas-making process, the also impact of air and steam by compression of moulded coal (ball, rod), add the gross weight of coal in stove, so, through tackiness agent, bonding moulded coal must have certain withstand load power (ultimate compression strength), and this withstand load power will guarantee by certain cold strength.
At present, domestic tackiness agent price is high, makes addition in the coal briquette process and too much makes cost up, and ash content increases large, the cold strength of moulding coal briquette is on the low side, easily broken while being subject to surging force, the load request of coal briquette thickness and weight after can not meeting long-distance transport, air storage and entering stove.
