Frequent problems during the use of testing machines
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.

Common faults:
The dial pointer has poor sensitivity and stops halfway after unloading, or the zero position often changes. There are many reasons for this phenomenon.
1. The pulley on the gear rod and its rails are dusty and rusted. At this point need to remove clean, add a little clock oil.
2. The pointer shaft is dirty and should be cleaned.
3. The contact between the pinion and the pinion should be loosened.
4. Buffer oil return situation is bad, should be adjusted or cleaned.
5. The belt on the force measuring piston is detached or too loose (makes the piston unable to run at a constant speed).
6. The friction force of the force measuring piston is increased or stuck in the cylinder. Apply chromium oxide paste to research until it is normal.
7. The pendulum has obstructions in the lifting process, or the shaft is dirty or rusted, causing the pointer to change back to zero.
Common faults II:
When doing a tensile test, the specimen fracture always breaks on both sides. The reason for this phenomenon, first of all, should consider whether the installation of the main part of the test machine is vertical. If such reasons are excluded, then the following three aspects should be excluded.
1. The jaws are not placed positively when they are clamped. The jaws should be clamped symmetrically as required.
2. Poor quality jaws, damaged teeth, in addition to affect the jaws of different hearts, but also make the test specimen slip, so that the yield point is difficult to identify. The jaws should be replaced at this time.
3. Lift guide wheel is not adjusted properly, so that the upper and lower jaws do not feel the same. A test bar shall be machined, and the upper and lower jaws shall be tightened. The two force columns shall be used as the basis for measurement with a dial indicator until the adjustment is qualified.
Common fault three:
The position of the pendulum is not normal and the pendulum is not allowed to mark vertically.
The main reason is that the viscosity of the oil is too large or the oil is dirty. Remedy: Replace the oil with the proper viscosity.
Forced piston rotation has greater friction or does not rotate. Remedy: Check whether the test machine is horizontal and eliminate the failure of the measuring piston.
There is unstable friction. Remedy: Clean the pendulum shaft bearings, gear rods, pointers, and reels, adjust the test machine level, and reduce the existence of unstable friction.
Common faults four:
Hammer return is not normal, when fast.
Normally, the bumper can be screwed into place. However, if the oil hole of the damper is clogged, or if the ball or the contact portion of the ball of the damper valve is dirty or the clearance is too large, the damper will be disabled. The solution is to clean the buffer valve and adjust the gap between the ball and the seat to about 0.5mm. Place the oil needle knob so that the gap between the oil needle and the valve body is reduced, and re-list the ABC mark. Also, when the temperature has a great influence, the oil can be properly replaced.
Common fault five:
Passive needles do not stop well in any position and do not coincide with the main needle.
The exclusion method is to remove the dial glass, adjust the passive needle compression spring screw, and adjust the pointer so that it coincides with the main needle.
Common fault six:
At the time of loading, the oil system leaked heavily or the tubing broke.
First of all, check whether the joints of the oil system are tightened. If it is necessary to replace the gasket, replace it in time. If the tubing ruptures, then a higher-strength tubing needs to be replaced. In addition, the delivery valve must be observed and the overflow valve piston should be top dead or reversed.
Common fault seven:
After the specimen breaks, the pendulum quickly falls back, causing an impact.
The main problem is the failure of the buffer. In addition to routine adjustments, we should also consider whether the oil is too thin or dirty.
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.
