Many people are very strange to the wires in their homes, and think that those things should be arranged in such a way, but in fact, as the basis of family life, the wires are crucial, and then we will introduce them to you by Xiaobian!
Wires must be piped in the wall. Generally, there are two kinds of metal pipes and PVC pipes:
Metal pipes are more expensive, but the anti-interference performance is stronger than that of PVC pipes. They are not afraid of fire, and the protection of wires will be stronger than PVC pipes in the future.
PVC pipe is affordable, it is easier to turn than metal pipe and has good insulation performance. In fact, the general family chooses PVC pipe is very good, just choose to be strong, the simple way is to use the foot to step on, it will be good to not be hi-hat. Finally, please note: no matter which type of threading pipe is used, the wire cannot have a joint in the pipe.
1. Wire surface marking. According to national standards, the surface of the wire shall have a continuous mark of the name of the manufacturer, the type of the product and the rated voltage. This helps to find the manufacturer in time when problems occur during the use of the wire. Consumers must pay attention to this when purchasing wires. At the same time, consumers should pay attention to the manufacturer's name, product model, rated voltage and the printed mark on the surface of the wire when purchasing the wire to prevent counterfeit products.
2, the appearance of the wire. When purchasing electric wires, consumers should pay attention to the appearance of the wires should be smooth and flat, the insulation and the sheath layer are not damaged, the logo is printed clearly, and there is no greasy feeling when the hand touches the wires. From the cross section of the wire, the thickness of the insulation or sheath on the entire circumference of the wire should be uniform and should not be eccentric. The insulation or sheath should have a certain thickness.
3. Conductor wire diameter. When purchasing electric wires, consumers should pay attention to whether the conductor wire diameter matches the cross section clearly indicated on the certificate. If the conductor cross section is small, it is easy to cause the wire to heat up and cause a short circuit. It is recommended that household lighting lines use 1.5 square millimeters and above; household appliances with high power such as air conditioners and microwave ovens should use wires of 2.5 square millimeters or more.
4. Standard use. Wiring should be standardized. It is best to use BV single-core wire to wear the fixed line. Be careful not to damage the wire during wiring. Do not damage the wire when decorating the room; do not connect the connector in the middle of the route; connect the wire and cable to the electrical box (box) Don't touch the line.

Potassium Chloride, Magnesium Chloride, Calcium Chloride are normally used in food additives, low-sodium salts as stabilizer, nutrition supplement, salt substitute, gelling agent, yeast food, condiment, pH regulator, tissue softening agnet etc.
The Chloride ion /ˈklÉ”Ëraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water.[4] It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells. Less frequently, the word chloride may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion.
A chloride ion is much larger than a chlorine atom, 167 and 99 pm, respectively. The ion is colorless and diamagnetic. In aqueous solution, it is highly soluble in most cases;
Sea water contains 1.94% chloride. Some chloride-containing minerals include the chlorides of sodium (halite or NaCl), potassium (sylvite or KCl ), and magnesium (bischofite), hydrated MgCl2. The concentration of chloride in the blood is called serum chloride, and this concentration is regulated by the kidneys. A chloride ion is a structural component of some proteins, e.g., it is present in the amylase enzyme.
Role in commerce.
The chlor-alkali industry is a major consumer of the world's energy budget. This process converts sodium chloride or Potassium chloride into chlorine and sodium hydroxide or Potassium hydroxide, which are used to make many other materials and chemicals.
Water quality and processing:
Another major application involving chloride is desalination, which involves the energy intensive removal of chloride salts to give potable water. In the petroleum industry, the chlorides are a closely monitored constituent of the mud system. An increase of the chlorides in the mud system may be an indication of drilling into a high-pressure saltwater formation. Its increase can also indicate the poor quality of a target sand.
Chloride is also a useful and reliable chemical indicator of river / groundwater fecal contamination, as chloride is a non-reactive solute and ubiquitous to sewage & potable water. Many water regulating companies around the world utilize chloride to check the contamination levels of the rivers and potable water sources.
An example is Potassium chloride, which is Potassium chloride with the chemical formula KCl. In water, it dissociates into K+ and Cl− ions. Salts such as calcium chloride, magnesium chloride, potassium chloride have varied uses ranging from medical treatments, food additive to industrial applications.
Calcium chloride (CaCl2) is a salt that is marketed in pellet form for removing dampness from rooms. Calcium chloride is also used for maintaining unpaved roads and for fortifying roadbases for new construction. In addition, calcium chloride is widely used as a de-icer, since it is effective in lowering the melting point when applied to ice.
