Net floats, insoles, stoppers, etc. There are records of cork in the Spring and Autumn Period. The main species of cork produced are cork oak and cork oak. Plants that are 20 years old or older and have a breast diameter greater than 20 cm can be subjected to secondary stripping. The resulting skin is called the first or the first skin. Afterwards, it is peeled off every 10 to 20 years, and the obtained skin is called regenerated skin, and the skin thickness is 2 cm or more.
Cork characteristics:
This structure gives the cork a very good elasticity, sealing, heat insulation, sound insulation, electrical edge and abrasion resistance, plus the advantages of non-toxic, odorless, small specific gravity, soft hand feeling, and not easy to catch fire. No artificial products are comparable. In terms of chemical properties, a mixture of esters formed from several hydroxy fatty acids and phenolic acids is a characteristic component of cork, collectively referred to as softwood.
These substances are resistant to decay and chemical corrosion. Therefore, they do not have chemical effects on water, oil, gasoline, organic acids, salts, esters, etc., except for concentrated nitric acid, concentrated sulfuric acid, chlorine, and iodine. It is widely used, such as bottle stoppers, thermal layers of refrigeration equipment, lifebuoys, and acoustic panels.
The cork cutting machine is characterized in that when the punching head acts on the workpiece through the die, the pressure in the working cylinder does not reach the rated pressure, and the pressure will increase as the contact (cutting into the workpiece) increases. The electromagnetic reversing valve receives the signal, the reversing valve is reversed, and the punching head starts to reset; at this time, the pressure in the cylinder may not reach the set rated pressure value due to the time limit of the pressure oil entering the cylinder; that is Say, the system pressure has not reached the design value, and the die cutting has been completed.
The scope of use of cutting machine: suitable for foam materials, cardboard, textiles, plastic materials, leather, rubber, packaging materials, flooring materials, carpets, fiberglass, cork and other non-metallic materials through the die to achieve the material by the pressure generated by the machine Punching and cutting.
