Abstract
The invention provides a lightweight argil and shale perforated ganged brick and a production method. The lightweight argil and shale perforated ganged brick is characterized in that a blank is mainly prepared from the following raw materials in percentage by mass: 60% of shale, 20 to 25% of soybean straw, and 20 to 25% of other auxiliary materials; the auxiliary materials include 80 to 90% by mass of quicklime, and 10 to 20% by weight of iron powder; the argil mud is Guangxi Qinzhou Nixing argil mud containing 50 to 55% of water. The production method is that the prepared argil mud is uniformly sprayed on the blank until the thickness of 1 to 3mm is reached, and then roasting the blank for 8 to 12 hours at the temperature of 950 to 1200 DEG C so as to obtain the finished product. The lightweight argil and shale perforated ganged brick has the advantages of smooth surface, regular appearance and diverse finishing effects, and is outstanding in heat preservation, heat insulation, sound insulation, waterproofing performance, freezing resistance, non-discoloring performance, durability, environmental protection, and non-radiation performance; the lightweight argil and shale perforated ganged brick can be applied to indoor and outdoor as the ganged block.
Description
Technical field
The present invention relates to building material field, particularly a kind of lightweight clear water potter's clay shale porous brick and production method.
Background technology
The production method of ordinary sinter shale porous brick be shale is pulverized, shaping after, follow procedure carries out roasting and makes.Although ordinary sinter shale porous brick is hollow brick at present, because internal voids is less, particle is closely knit, and the shale required for every block brick is still more, and its density is still larger.And due to the character of the material of shale own, the frequent indivedual local uneven color in ordinary sinter shale porous brick surface, is also difficult to accomplish smooth bright and clean.In addition, ordinary sinter shale porous brick water-intake rate is large, and freeze proof capacitive is poor, is unsuitable for being used as clear water brick and uses.
Summary of the invention
Object of the present invention is just to provide a kind of from heavy and light, and any surface finish, the lightweight clear water potter's clay shale porous brick that quality is attractive in appearance and production method.
Solution of the present invention is such:
A kind of lightweight clear water potter's clay shale porous brick, comprise potter's clay mud and adobe, blank is made primarily of the following raw material containing mass percent: shale 60%, soybean stalk 20%-25%, other auxiliary material 20%-25%, and wherein auxiliary material is made up of unslaked lime 80%-90%, the iron powder 10%-20% of mass percent; The Guangxi Qinzhou Nixing pottery mud of potter's clay mud to be water ratio be 50%-55%, thick for the spraying 1mm-3mm of the potter's clay mud slurry uniform prepared removing two slurry surfaces in adobe are left 1 or any number of in four sides, finally under 950 DEG C of-1200 DEG C of conditions, carry out roasting and keep can obtaining finished product in 8-12 hour.
Technical scheme also comprises more specifically: described Guangxi Qinzhou Nixing pottery mud comprises and is mainly distributed in by the emperor himself bank region, the east of a river, be positioned at region, low lying areas, external appearance characteristic is that compact substance is soft, for soft clay, color is slightly yellow-white in redness, also referred to as white clay, iron-holder is high, and contain the eastern mud of micro-quartz sand and be distributed in Jiangxi bank by the emperor himself, storage ground is based on hillside, external appearance characteristic is compact mass, color is red-purple, therefore also referred to as purple mud, top layer has a small amount of irony to contaminate, for flint clay, plasticity-and the poor western mud of associativity, the western mud of the eastern mud and 35-45% of getting the 55%-65% accounting for total potter's clay quality respectively adds after ground and mixed is carried out in appropriate water mixing crosses 40 orders and 100 order twice comb, enter settling tank, leave standstill after mud sediment, the clear water on upper strata is drained, again mud is dewatered by pressure worry machine, again mud is made mud bar by the dehydration of pressure worry machine.Use the air in vacuum deairing machine pugging eliminating mud bar, then pug after old 15 days at dark place, is added water to stir and makes the potter's clay mud that water ratio is 50%-55%.
Further: described soybean stalk to be pulverized, dries.Make most its water ratio be down to 2%-3.5%, then, sieve, remove and be greater than the stalk of 8mm and be less than the soybean stalk powder of 0.1mm.
The production method of lightweight clear water potter's clay shale porous brick, comprises step:
(1) Slug preparing step: make primarily of the following raw material containing mass percent: shale 60%, soybean stalk 20%-25%, other auxiliary material 20%-25%, wherein auxiliary material is made up of unslaked lime 80%-90%, the iron powder 10%-20% of mass percent; Soybean stalk is pulverized, dries.Its water ratio is made most to be down to 2%-3.5%.Then, sieve, remove and be greater than the stalk of 8mm and be less than the soybean stalk powder of 0.1mm; Shale is pulverized and sieved to obtain slate flour; In slate flour, add soybean stalk powder and other auxiliary material that massfraction is 20%-25% and suitable water stir and make blank, blank is put into blank machine compacting, obtains adobe, adobe under 110-120 degree Celsius dry 12 to 24 hours;
(2) potter's clay slurry preparation process: adopt the slurrying of Guangxi Qinzhou Nixing pottery, comprise and be mainly distributed in bank region, the east of a river by the emperor himself, be positioned at region, low lying areas, external appearance characteristic is that compact substance is soft, for soft clay, color is slightly yellow-white in redness, also referred to as white clay, iron-holder is high, and contain the eastern mud of micro-quartz sand and be distributed in Jiangxi bank by the emperor himself, storage ground is based on hillside, external appearance characteristic is compact mass, color is red-purple, therefore also referred to as purple mud, top layer has a small amount of irony to contaminate, for flint clay, plasticity-and the poor western mud of associativity, add after ground and mixed is carried out in appropriate water mixing by the western mud of the eastern mud and 35-45% of getting the 55%-65% accounting for total potter's clay quality respectively and cross 40 orders and 100 order twice comb, enter settling tank, leave standstill after mud sediment, the clear water on upper strata is drained, again mud is dewatered by pressure worry machine, again mud is made mud bar by the dehydration of pressure worry machine.Use the air in vacuum deairing machine pugging eliminating mud bar, then pug after old 15 days at dark place, is added water to stir and makes the potter's clay mud that water ratio is 50%-55%.
(3) potter's clay step is sprayed: thick for the spraying 1mm-3mm of the potter's clay mud slurry uniform prepared removing two slurry surfaces in adobe are left 1 or any number of in four sides;
(4) calcination steps: carry out roasting under 950 DEG C of-1200 DEG C of conditions are put in the adobe after spray potter's clay and keep can obtaining finished product in 8-12 hour.
Advantage of the present invention adopts Nixing pottery soil to improve burned shale perforated brick surface property, not glazing, the finished product burnt out, smooth surface, outward appearance is regular, finishing effect is various, and there is good insulation, heat insulation, sound insulation, waterproof, freeze proof, nondiscoloration, the fine quality such as durable, environmental protection is "dead", can be used as clear water brick for indoor and outdoors.
