Abstract
The invention provides a pumice stone grinding block and a preparation method thereof; wherein, the preparation method of the pumice stone grinding block comprises the following steps: crushing natural and irregular pumice stones; adding auxiliary material and binder; calcining at high temperature or drying at low temperature to make homogeneous and regular pumice stone products with consistent performance and parameters. The pumice stone grinding block has the advantages of consistent parameters, low hardness and specific gravity, and wide application range in grinding, deburring, and improving the surface roughness of soft materials, such as copper, aluminum, wood, plastic, leather, textile, etc.
Description
Technical field:
The present invention relates to a kind of pumice goods, relate in particular to a kind of quality is even, performance parameter is unified pumice and manufacture method thereof.
Background technology:
Natural pumice is abundant, the cheap nonmetallic minerals of a kind of reserves, because its porous can be done friction material, especially its hardness is low, proportion is low, is fit to the friction soft material, and present successful Application is in the washing process of outlet clothes.But natural pumice exists quality inhomogeneous, shape, shortcoming such as cause diversified in specifications, and to use convenient inadequately, seriously limited its application at the other field of complex process, uses on the production line such as manufactured copper, aluminium, plastics, timber, leather and fur products.
Summary of the invention:
The purpose of this invention is to provide that a kind of quality is even, shape specification is consistent, the pumice goods that can conveniently use.
Technical scheme of the present invention is such: a kind of light stone grinding block, will be natural, erose pumice make pumice powder after pulverizing, be that 60~99: 1~40 pumice powder mixes with inorganic binder afterwards that high-temperature firing forms again by weight.
The invention provides another light stone grinding block, will be natural, erose pumice make pumice powder after pulverizing, be that 60~99: 1~40 pumice powder mixes with organic binder bond afterwards that low temperature drying forms again by weight.
Above-mentioned pumice powder is the micro mist after being pulverized, screened by natural pumice process, and the micro mist granularity is decided on the performance requirement of light stone grinding block, in order to increase friction effect, can mix other materials such as silica flour.
Above-mentioned inorganic binder can be inorganic simple substance material, as feldspar powder, talcum powder, clay etc., also can make these mixtures of material.
Above-mentioned organic binder bond is various resinae binding agents.
The invention provides the manufacture method of above-mentioned first kind of pumice module, comprise the steps:
A. pumice is pulverized, screened, obtain the designated size pumice powder;
B. weighing pumice powder and binding agent and mix in proportion;
C. add suitable quantity of water in the mixture and stir;
D. compression moulding and oven dry;
E. high-temperature firing to 700~1100 degree centigrade and being incubated to appropriate time;
F. size is cut on request.
The invention provides the manufacture method of above-mentioned second kind of pumice module, comprise the steps:
A. pumice is pulverized, screened, obtain the designated size pumice powder;
B. weighing pumice powder in proportion;
C. add organic binder bond and fully mixing in proportion;
D. compression moulding;
E. press 40~300 degrees centigrade of oven dry of low temperature appropriate time, concrete bake out temperature, time should decide on the type of organic binder bond;
F. by size cutting or pruning.
After the present invention pulverizes irregular pumice process, be pressed into required form after adding binding agent, pass through high-temperature firing or low temperature drying then, obtain the light stone grinding block that quality is even, parameter is consistent, thereby can be applied to more areas widely, better develop this mineral resources of pumice.
The specific embodiment:
The first embodiment of the present invention is a kind of manufacture method of pumice module, comprises the steps:
A. pulverize pumice with air separation disintegrator, filter out 80 order screenings, pack standby with linear vibrating screen.
B. 100 kilogram of 80 order pumice powder of weighing, 40 kilograms of feldspar powders fully mix.
C. add 10 premium on currency and stir.
D. mixed wet feed is put into the appointment mould, uses forcing press compression moulding.
E. the module after the moulding be placed on the drying box inner drying to water content less than 6%.
F. dried module is gone into kiln, fires by heating curve, and kiln scale and the requirement of light stone grinding block hardness are depended in the formulation of this curve, and general rule is will grow the big kiln heating-up time; The holding temperature height can cause light stone grinding block hardness height.
G. cut into the module of 10*10*100 millimeter.
In the foregoing description, described raw material include but not limited to pumice powder, feldspar powder, can also add an amount of clay, talcum powder, silica flour etc. as required, and main purpose is a little partial properties that changes light stone grinding block, as wearability, hardness, proportion etc.
Second embodiment of the present invention is another kind of light stone grinding block, comprises the steps:
A. pulverize pumice with air separation disintegrator, filter out 80 order screenings, pack standby with linear vibrating screen.
B. 100 kilogram of 80 order pumice powder of weighing.
C. the epoxy resin of 10 kilograms of weighings, and with acetone or dimethylbenzene dilution.
D. the epoxy resin after will diluting mixes with pumice powder and fully stirs.
E. compound is poured into and specified in the mould, use forcing press compression moulding.
F. the light stone grinding block after the moulding was put into 50 degrees centigrade of constant temperature dryings of drying box 6 hours.
G. cut into the module of 20*20*60 millimeter.
In the above-described embodiments, the size if die size conforms to customer requirements is then omitted the g step.Need to prove, the present invention is a scope of determining according to the light stone grinding block performance parameters of different purposes about the part by weight scope of pumice powder, bond, silica flour etc. with firing temperature, light stone grinding block after different auxiliary material, different proportion, different temperatures are fired, all can realize purpose of the present invention, it is the difference on the performance, therefore any change in the various material weight percentage range that contain for the present invention and being achieved still belongs within the scope of the present invention.
