  Introduction of carton stitching machine     The  corrugated carton stitching machine  is one of the subsequent processing equipment of the carton. Its principle is same as the ordinary stapler, except that the carton stitching machine uses tiger teeth as a backing plate, and is specially used for carton sealing. This series of products have the advantages of light weight, easy operation, good wear resistance, flat sealing, safe and firm, can reduce labor intensity and improve work efficiency. They are widely used in various applications that need to load heavy objects of box and calcium plastic box which are not easy to seal with adhesive tape.   At present, the commonly used carton stitching machines include semi-automatic and full automatic carton stitching machine. The semi-automatic carton stitching machine is mainly used for the nailing of single-sheet corrugated cardboard, to meet the requirements of various carton factories and different batch production. It is a substitute f

  Hands are the easiest way to spread germs, a small fraction of which are harmless, non-pathogenic microbes that normally live on human skin. Other types of bacteria found in the air and surfaces, such as viruses and bacteria, are responsible for many diseases, ranging from more common and less serious illnesses such as the common cold to more severe ones. Some bacteria can live on surfaces for hours and can enter your eyes, nose and mouth through your hands. Therefore, keeping hands clean is essential to prevent infection, both in social life and in healthcare settings such as hospitals, clinics and dental offices. 5 Critical Moments for Handwashing In healthcare facilities, hand washing is mandatory at 5 critical moments as defined by the World Health Organization 1. Before touching a patient You must wash your hands before touching a sick person, even with standard touches like approaching them or shaking hands 2. Before aseptic manipulation Use surgical brushes if possible, and wa

  Capacitors are among the crucial parts of many electrical devices. In this article from Linquip, we want to explain in detail the answer to  “ what is a capacitor ”  and  “ what are capacitors used for ” . By the end of this article, you will be able to fully understand the structure of a capacitor and how they work inside an electrical device. What is a capacitor? A capacitor is considered to be a device for storing electrical energy inside an electric field. This passive electronic component contains two terminals to help store energy. The two conductors inside a capacitor are insulated from each other and are in close proximity. The capacitor ’ s effect is called capacitance and capacitors are capable of adding capacitance to the circuit. Capacitors belong to a group called  “ passive components ” ; these components also include resistors and inductors. All these three elements are used inside electronic equipment. What does a capacitor do and how it works? Capacitors   are used f

  As an   NPK Compound Fertilizer Wholesaler , share with you. Compound NPK and NPK blends are multi-nutrient fertilizers, of which three main nutrients (nitrogen (N), phosphorus (P) and potassium (K)) account for a certain proportion. These products are designed to be fully fertilized in one application. The raw material source of each nutrient may vary according to the production process of the finished NPK fertilizer. NPK Compound Fertilizer In the production of  compound NPK , some of the processes used are proliferative. The fertilizer slurry is repeatedly applied to the solid "seed" particles and dried to form an "onion skin" structure similar to that produced by "DAP or MAP". Other compounds, NPKs, are prepared by an agglomeration process, where the main raw materials are fed in the form of dry solids, and then interlocked and cemented by steam, liquid salt solution, ammonium phosphate slurry and/or ammonium nitrate solution. However, in addition to

Grey cast iron  is a type of iron that is characterized by its grey color and graphite flakes, which are dispersed throughout the material. It is a relatively inexpensive and readily available material that is widely used in the casting industry for a variety of applications. Grey cast iron is produced by melting pig iron, which is a raw form of iron, along with scrap steel and other alloying elements in a furnace. The molten metal is then poured into a mold, where it solidifies and takes the shape of the mold. This process is known as  casting grey iron ​ is called grey because of the color of the surface of the casting after it has cooled.   There Are Several Factors That Can Affect the Quality of a  Grey Cast Iron Casting . These Include: Raw Materials The quality of the raw materials used in the casting process is critical to the quality of the finished casting. It is important to use high-quality pig iron and other alloying elements to ensure that the finished casting has the desi

    Zinc carbonate   can be used in a variety of fields and locations, some of which will be described in this article. In Veterinary Medicine Zinc carbonate can be used as an astringent, antiseptic and topical wound protector in animals. It also helps to prevent diseases caused by zinc deficiency, which is why it is used as a  supplement to the diet of some animals , provided that the dosage meets the standards set by the WHO. Zinc carbonate is sometimes used as a micronutrient for the prevention of diseases in animals. In Medical Treatment This compound can be obtained in some pharmaceutical products. It is applied to inflamed skin in the form of a powder or a lotion. In dental therapy Certain toothpastes based on zinc carbonate and hydroxyapatite nanocrystals are regularly applied on dentures. It is more effective in reducing hypersensitivity than fluoride based toothpastes. The size, shape, chemical composition and crystallinity of ZnCO3 and hydroxyapatite nanocrystals are similar
