Abstract
A production method of hollow brick includes the following steps: using clay as raw material, double-roll pulverizing, mixing with internal fuel, stirring, extruding to obtain mud strip, cutting into blank, spreading dry sand, press moulding, then drying and baking to obtain the said invented finished produt. The steps of premoulding brick balnk, spreading dry sand and press moulding are important procedures, and the dry sand is used for absorbing water content from surface of brick blank, preventing the brick blank from cracking in the process of drying and firing and isolating the brick from mould to make brick apperance complete.
Description
The present invention relates to a kind of working method of hollow brick for building.
At present, the middle-size and small-size brick field of China is also all produced solid brick, does not meet national materials for wall reform spirit, requires to popularize to produce and uses hollow brick.And hollow brick is than solid brick complex manufacturing, and difficulty is big, used shale required high.China generally adopts extrusion molding processing hollow brick, to southern mountain soil and northern lean property soil, adopts extrusion molding processing hollow brick, and technology is very difficult, the cost height.In recent years, also have and adopt the pressure forming mode to process hollow brick, not only the sintering difficulty is easy to crack, and yield rate is low, cost height, and the equipment of original production solid brick, and production system can not effectively be utilized.
Purpose of the present invention is the working method that a kind of structural clay tile that extrusion moulding and pressure forming are combined will be provided.
Technical process of the present invention is: raw clay is pulverized, is mixed interior fuel, stirring, squeezes the mud bar through pair roller, cuts base again, spreads dry sand, compression moulding, and dry then, roasting get hollow brick of the present invention.
, same as the prior art from raw material pulverizing to each operation of squeezing the mud bar.
Cut base: the mud bar is cut into the hollow brick blank by standard.
Spread dry sand: after cutting blank, dry sand is sprinkling upon blank surface equably.
Compression moulding: will speckle with the blank of dry sand, and deliver to shaper, and be pressed.
Dry: because of the more solid green strength of hollow blank is low, sign indicating number base height is advisable with 5～6 layers, and blank hole direction is parallel with the drying medium direction, is advisable with rare sign indicating number, and the base substrate each several part can be touched with the drying medium knot.
Roasting: during roasting, warm up time is more a little longer than solid brick, prevents quick heating, cracks.Be advisable with 900～950 ℃.
Precompose moulded pottery not yet put in a kiln to bake, stucco and compacting are important procedures of the present invention, and dry sand absorbs base face moisture content, prevent drying and burn till crackle, and the buffer action when playing compacting, the demoulding makes the adobe outward appearance complete.Technology of the present invention can just be used the existing equipment condition, popularizes easily.
Claims (2)
1, a kind of working method of hollow brick is pulverized raw clay, mix interior fuel, stirring, squeezes the mud bar, is cut base, drying, roasting through pair roller, hollow brick, it is characterized in that: after squeezing the mud bar, cutting base, spread dry sand, compression moulding again, dry then, roasting.
2, by the working method of the described hollow brick of claim 1, it is characterized in that: after cutting base, dry sand is sprinkling upon blank surface equably; When dry, sign indicating number base height is advisable with 5～6 layers, and blank hole direction is parallel with the drying medium direction; Roasting is advisable with 900～950 ℃.
