Abstract

The invention discloses black pottery manufacturing technology, specific make step is as follows：(1) green body is made, the type of required ceramics is made of deployed pug.(2) enter kiln, enter to be packed into kiln firing when green body is done to moisture content 15% or so.(3) latter stage is fired, is exactly in the final stage close to firing.(4) timber is added, moisture content is added 10% in firing latter stage --- 50% timber allows in kiln and produces thick smoke.(5) sealing carbonization seals dense smoke in kiln and generates pressure, keeps sootiness duration 5 --- 45 minutes, make green body carbonization transmutation, coloring.(6) it is burnt into, reaches after firing temperature and above-mentioned indices that is, flame-out its natural cooling that allows.The present invention has simple for process, easy to operate, production safety, and pottery quality made from low manufacture cost and energy is high, the strong advantage of aesthetics.

Description

The firing new method of black pottery

Technical field：

This technology invention is related to a kind of production of ceramics, manufacturing process, applies in Production of Ceramics, production field.

Technical background：

Black pottery is a kind of ancient ceramics, and the method used is that some water are added from kiln top in the final stage of firing, So that charcoal extinguishing is produced thick smoke, allows the having the problem of oozing charcoal technique, exist here of sootiness green body：.

(1) high temperature meets the steam of water generation to security risk existing for operating personnel.

(2) pollution of the dense smoke to environment.

(3) product meets water cracking.

(4) green body coloring is uneven.

Invention content：

The technical problem to be solved by the present invention is in order to overcome present technical deficiency, provide a kind of simple for process, operation letter Just, production is safer, more environmentally friendly, improves the qualification rate of product, makes product coloring evenly, can obtain quality higher, sees The new production method of the stronger black pottery product of reward property.

In order to solve the above-mentioned technical problem the present invention uses following scheme：

(1) electrical kiln is used to fire, to achieve the effect that seal high pressure.

(2) water content is added 10% in the final stage of firing --- 50% pine, and kiln is sealed immediately, and protect Card kiln in have 5 --- 45 minutes dense smoke, this can according to the built-in base amount of thickness and kiln of green body number, do corresponding tune Whole, green body is thick, and the time of dense smoke is just appropriately extended greatly in green body loading of kiln amount, conversely, green body is thin, loading of kiln base amount is few, so that it may reduce dense The time of cigarette.

Reached by the improvement of the above method：

(1) due to the sealing of kiln, high pressure is generated, making to ooze the charcoal transmutation time shortens.

(2) do not have to plus water avoids the hidden danger scalded by steam without steam generation.

(3) it is sealed immediately after producing thick smoke, so that dense smoke is not leaked using the sealing effect of electrical kiln, reached environmental protection Effect.

(4) product does not meet the possibility of water, avoids and meets water quick cooling blank cracking.Improve product qualification rate.

(5) dense smoke ooze charcoal time it is controllable, achieved the effect that uniform coloring.

Technical scheme of the present invention：

This method fires black pottery, uses electrical kiln, because electrical kiln does not have, fire hole, quirk, flue, and chimney.Can thus it reach Seal the effect of high pressure.Moisture content is added 10% in the final stage of calcining black pottery --- 50% pine simultaneously shuts kiln immediately Door, the amount that pine is added are determined depending on the amount of green body thickness and loading of kiln green body, ensure the time of dense smoke in kiln 5 --- 45 minutes Between.Then its natural cooling is allowed.

The Essential Action and advantageous effect of this technology：

It is with unique no glaze without color high pressure charcoal to use the pure black that is showed of black pottery surface that this technology is fired Made of changing the new process firing of transmutation, it is exactly the black being like nature itself after kiln discharge, no longer does any processing.Its appearance is black such as Paint, bright such as mirror, hard such as porcelain, sound such as use up, have very high ornamental value and practicability, there is unique artistic charm and collection valence Value.

And keep production link safer, and it is more environmentally friendly, improve productivity effect and product amount.

Claims

1. the firing new method of black pottery using electrical kiln it is characterized in that, sealed, the black pottery that high pressure sootiness carbonization transmutation is fired into Device.It is as follows：

(1) it seals, uses electric kiln to achieve the effect that seal high pressure.

(2) sootiness is firing latter stage addition moisture content 10% --- 50% timber.

(3) be carbonized transmutation, and dense smoke duration is 5 in holding kiln --- and 45 minutes.

2. according to the calcining black pottery new method described in claim one, it is characterised in that；Sealing, high pressure are generated using electric kiln.

3. according to the calcining black pottery new method described in claim one, it is characterised in that；Moisture content is added in the latter stage of firing to exist 10% --- 50% timber.

4. according to the calcining black pottery new method described in claim one it is characterized in that；Dense smoke duration is 5 in holding kiln --- 45 minutes.
