Description

A kind of mud emerging pottery particle perpetual calendar and manufacture craft thereof
Technical field
The present invention relates to a kind of perpetual calendar, be specifically related to a kind of mud emerging pottery particle perpetual calendar and manufacture craft thereof of doing with the emerging ceramic of Guangxi Qinzhou mud.
Background technology
Calendar, year calendar in the middle of existing all is to change in 1 year one, can not reuse, and not only wasted resource but also not environmental protection.For this reason, people have researched and developed can reusable perpetual calendar, mainly comprises two large classes, the one, the electronic device class, the demonstration that it utilizes control chip control date etc. realizes using for a long time, but this electron-like apparatus structure is complicated, cost is larger, and needs to consume the energy; The 2nd, active card or rotating disk etc., it is by mobile card per month or rotate rotating disk week and the Gregorian calendar, the lunar calendar etc. are complementary, this class perpetual calendar is difficult for preserving, and such as the perpetual calendar of card form, Nian Jiuhui fades aging, and reserve value and cultural deposits are inadequate, and the mechanical perpetual calendar of rotating disc type, its complex structure, mechanical component can get rusty because making moist, occur rotating fault, can't finish the work.
Summary of the invention
Technical matters to be solved by this invention provide a kind of reusable, be easy to preserve the emerging pottery particle of mud simple in structure perpetual calendar.Simultaneously, the present invention also provides the manufacture craft of the emerging pottery particle of a kind of mud perpetual calendar.
For solving the problems of the technologies described above, the emerging pottery particle of a kind of mud perpetual calendar of the present invention's design, comprise main body frame, with the block that indicates month, date and week, described month, date and week block made by the emerging potter's clay of mud, wherein block is to indicate 12 blocks that January~Dec forms month, and the date block is to indicate 2~31 30 blocks that form, week block be indicate day, one, two, three, four, five, six 7 blocks that form; Offer 49 block sockets arranging with the supporting 7*7 matrix of block on the described main body frame, the first row socket is inserted with day from left to right, one, two, three, four, five, six block, first socket of the second row begin by mate when per medio week successively activity be inserted with the date block, wherein No. 1 date with month in this month block represent; All the other, block was plugged on the socket of vacancy in month.Perpetual calendar of the present invention, can be according to week every month and date corresponding, rearrange, obtain of that month calendar watch, can reuse, both environmental protection, and because of block be that the emerging potter's clay of mud is made, so be easy to again preserve, do not have the mildew phenomena that fades and occur, can forever use.
The described main body frame of such scheme can be made by the emerging potter's clay of mud.
The described block of such scheme can be rectangular parallelepiped or square, and its height is greater than the degree of depth of socket.
The manufacture craft of the emerging pottery particle of a kind of mud of the present invention perpetual calendar may further comprise the steps:
1) preparation blank: get 4~6 parts in 5~6 parts in eastern mud and western mud and pulverize, and mix respectively, again to the further desanding of blank, make that the content of silicon dioxide is lower than 76% in the blank;
2) blank forming: make in the same size, uniform graininess block base substrate with blank;
3) repaired biscuit: base substrate is repaired to reach designing requirement;
4) body drying: base substrate is carried out drying process, base substrate moisture is discharged;
5) decorate base substrate: writing words on base substrate;
6) base substrate biscuiting: the base substrate after decorate processing is put into kiln, temperature is raise gradually, with 40~50 ℃ the programming rate of per hour raising temperature is risen to 100~200 ℃, and under this temperature, continued to fire 0.5~1.5 hour;
7) repoussage base substrate: the base substrate after the biscuiting is taken out, when also having a surplus temperature, base substrate is flattened finishing and process;
8) fire: the base substrate behind the repoussage is put into kiln, first with 50~100 ℃ the programming rate of per hour raising temperature is risen to 500~900 ℃, and under this temperature, continued to fire 1~2 hour; With 150~200 ℃ the programming rate of per hour raising temperature is risen to 1050~1170 ℃ again, and under this temperature, continued to fire 2~3 hours; Kiln discharge obtains block of the present invention after cooling.
Can certainly be with the framework of above-mentioned manufacture craft production perpetual calendar of the present invention.
The emerging pottery of mud is in sintering procedure, and the principal element that cause the shape of the emerging pottery of mud to change, to ftracture is quartz high temperature (1100~1200 ℃) expanded by heating and smectite low temperature (100~200 ℃) dehydration.And for block can being inserted in the socket, and can be good with the matching degree of socket, be difficult for deviating from, particle is more even, namely in sintering procedure, the shape of block can only change among a small circle, so manufacture craft of the present invention will strictly be controlled the degree of expansion of base substrate, for this reason when making blank, further desanding, quartz content in the blank reduces, and reduces its degree of expansion; And, increased slowly biscuiting process of low temperature, be in order to make smectite when dewatering, block is heated evenly, to shrink consistent; After biscuiting, base substrate is flattened in addition, can make block more even, shape is more regular, and this is to have different places from the manufacture craft of the emerging pottery of existing mud.
Such scheme is described can be in step 1), and again to the further desanding of blank, the content that makes silicon dioxide in the blank is 50~65%.
Such scheme is described can be in step 6), put into kiln to the base substrate of decorating after processing, and temperature is raise gradually, with 30 ℃ the programming rate of per hour raising temperature is risen to 150 ℃, and under this temperature, continues to fire 1 hour.
Such scheme is described can be in step 8), and the base substrate after the finishing is put into kiln, with 75 ℃ the programming rate of per hour raising temperature is risen to 700 ℃ first, and under this temperature, continues to fire 1.5 hours; With 175 ℃ the programming rate of per hour raising temperature is risen to 1120 ℃ again, and under this temperature, continued to fire 2.5 hours; Kiln discharge obtains block of the present invention after cooling.
Compared with prior art, the present invention has the following advantages:
1, perpetual calendar of the present invention, its block and/or framework are made by the emerging potter's clay of mud, and year can not faded for a long time, be gone mouldy, and can use for a long time, extremely environmental protection; And the works of mud emerging pottery, particularly great master have certain reserve value;
2, manufacture craft of the present invention, further desanding reduces quartzy content, reduces the degree of expansion of base substrate, makes the change of shape scope of base substrate little, can mate preferably socket;
3, the slow biscuiting of base substrate low temperature is heated evenly smectite block when dehydration, shrinks consistent; After biscuiting, base substrate is flattened in addition, can make block more even, shape is more regular.
