One, acid-proof brick sticks a shop to should press following program to undertake partly
Technological process of acid-proof brick construction pursues
Stick a shop note of acid-proof ceramic tile:
When having ceramic tile of line build by laying bricks or stones, bricky board fault is seamed arrange, the brick that be the same as a layer is seamed should stagger the 1/3~1/2; of bricky board width is adopted knead brick of crowded law line, ash is seamed should full and close-grained, ash seams the surface to press smooth; to establish face brick at any time height of successive line build by laying bricks or stones, answer to suit with photograph of daub gel time, prevent press press of body of build by laying bricks or stones to be out of shape brick of; planar line, should prevent to slide; line brick combines a ply to be 6-8 ㎜, seam wide for 3-4 ㎜.
2, acid-proof brick sticks a shop matrix examination and check and accept:
1, bricky board sticks a shop to be concrete foundation, these matrix close at undertaking examining check according to concerned regulation or standard before construction, eligible and rear can undertake construction.
2, the surface of concrete solid, close-grained, level off, not due the blemish such as face of an arenaceous, break, beehive, hemp.
3, exterior flatness is checked with 2 meters of straightedge, allow space to should not be more than 5 ㎜, gradient should accord with design regulation.
4, concrete solidify is complete, the water content inside 20 ㎜ should be less than the surface 6% .
5, construction surface is clean, must not leave the broken bits of ash having surplus, cement, hangover such as reinforcing steel bar.
6, aperture of the conduit that every crosses acid-proof brick to stick lay up, bushing, obligate, bury beforehand wait to all answer at the brick board before sticking a shop, finish.
3, the finishing when acid-proof brick pave:
To increase the bonding strength of daub and matrix, the construction surface of matrix goes at construction advancement finishing, in order to keep clear of besmear of processing of tool reference plane of examination of matrix of solidify of use conserve of acidification processing delivery brushs construction of bottom coating separator blemish of inspection of quality of build by laying bricks or stones of line of build by laying bricks or stones of bricky board line repairs raw material quality to check bricky board to clean stoving puddle to make up daub to match produce the expected result having a competition bricky board discharges treatment beforehand, use dry and cleaner, clean compression air or brush are cleared dust.
1, concrete matrix finishing:
Broken bits of the float ash the surface, cement and loose place answer to clear clean before construction, appropriate of basic level finishing uses emery wheel or steel wire is brushed wait for burnish surface, brush with dry down next, compress air or cleaner to clear clean. If the moisture content of concrete surface is more than 6% , should be in 40, the drying below 60 ℃ 3 day and night, be less than till moisture content 6% till. Be more than 0.5 ㎜ break to concrete surface, the diameter exceeds the beehive of 2 ㎜ to should undertake repairing.
2, separator finishing: The finishing of separator, the requirement that should impose man-hour surface according to all sorts of separator chooses the method of finishing and grade.
