Abstract
The invention relates to a method for improving the quality of domestic soft cork, and belongs to the technical field of cork product processing. The method comprises the following steps of: putting the cork into a closed iron pan, adding a chemical solution, cooking at certain temperature under certain pressure for certain time, and quickly relieving pressure and reducing temperature to expand and soften the cork, so that the aim of improving the quality of the cork is fulfilled.
Description
Technical field
The modification method of a kind of cork quality of application of the present invention belongs to the cork article processing technique field.
Background technology
Soft leather cork trees grow in climatic conditions, soil conditions are suitable barren regions, mainly in the west bank of the Mediterranean basin, such as Algeria, Tunisia, Portugal, Spain and other countries, in China Qinling Mountains, Yunnan, Guangxi and other regions are also produced.External cork quality is good, skin depth more than 2cm, have in addition reach 6～8cm, good springiness, flexibility is good, heat insulation performance might as well, and utilization rate is also high, is the preferred materials of producing various cork products.The cork quality that China produces is just much poor, and skin depth seldom surpasses 2.5cm, and entire body is stiff, poor flexibility.But external cork costs an arm and a leg, and is about 7～10 times of the prices of domestic cork.So in the cork at home, the good cork of using character, and only in homemade cork, abandon the poorer part of more quality, select the part of quality better for use.
Summary of the invention
The purpose of modification method that the present invention relates to the quality of cork is to waste the defective of a large amount of corks in order to solve above-mentioned prior art, and a kind of processing ease is provided, the method that the quality of domestic cork is necessarily improved; That is,, add finite concentration NaOH solution mainly through cork being positioned in the iron pan of sealing; Boiling certain hour under the condition of certain temperature and pressure, fast release of pressure cooling again makes the volume of cork obtain Peng and rises; Material is softening, receives the purpose of improvement cork quality.
The inventive method is to realize through following technical scheme:
A. in a volume is the big iron pan of 4M3, freely pile homemade cork, seal with iron covering again.
B. toward the big iron pan implantation concentration of sealing be 0.12% NaOH solution to full, heating then until the water boiling, makes temperature reach 120 ℃, pressure reaches 120Kpa, opens iron covering behind the boiling 12h and homemade cork is taken out dries.
The specific embodiment
A kind of modification method of cork quality, can adopt following concrete mode to implement:
Using thickness is the iron pan of one 2000 * 2000 * 1000 of 8 iron plate welding, and the pot cover that water valve is housed is connected with a pot body through sieve bolt.In the iron pan sky jack lift is installed.Fill with jack lift cork with iron pan, fasten pot cover and iron pan again.Be that 0.12% NaOH solution is filled with iron pan through the water valve of pot cover with concentration then; Fire then and heat, until boiling, this moment temperature at 105 ℃ of left and right sides pressure about 120Kpa. digestion process needs 12h; Promptly open pot cover afterwards, unload cork solarization airing and get final product.
Claims (5)
1. the modification method of a cork quality is characterized in that cork is positioned in the iron pan of sealing, adds a kind of chemicals solution, boiling certain hour under certain temperature and pressure condition, release of pressure cooling fast again.
2. want the modification method of art 1 described a kind of cork quality according to right, it is characterized in that added a kind of chemicals solution is that concentration is 0.12%NaOH solution.
3. want the modification method of art 1 described a kind of cork quality according to right, it is characterized in that boiling under 120～150 ℃ temperature conditions.
4. want the modification method of art 1 described a kind of cork quality according to right, it is characterized in that boiling under the pressure condition of 120KPa.
5. want the modification method of art 1 described a kind of cork quality according to right, the time that it is characterized in that boiling is 12h.
