Safety Tips Of Commercial Dry Cleaning Machines Use




Commercial dry cleaning machines are more common in everyday life, dry cleaning from Europe, previously also tried different dry cleaning agents, such as gasoline, carbon tetrachloride, trichlorethylene, trichlorotrifluoroethane and so on. The longest used is dry cleaning agent - tetrachlorethylene, which has so far been grown for 70 to 80 years in many developed countries in Europe, Australia and North America.
  
Tetrachlorethylene Commercial Dry Cleaners still holds more than 80% of the share. Since tetrachlorethylene has a micro-toxicity, long-term exposure to tetrachlorethylene is harmful to health. Although domestic environmental protection does not limit the concentration of tetrachlorethylene, the design and use of dry-cleaning machines should be considered so that the operator Avoid or reduce exposure to tetrachlorethylene. Therefore, many countries in the world have made regulations on the allowable concentrations of tetrachlorethylene gas in the working environment. The allowable range is between 25PPM and 50PPM. China provides 200 mg / m3 (ie 27PPM, GB16204-1996). This is a standard with the world's developed countries and more stringent standards.
 

 
As we all know, alcohol is also a toxic solvent. Human daily alcohol consumption to million units, but not see how many people drink alcohol-containing toxic solvents and poisoning is mainly because the control degree, no more than human acceptance of toxic standards, which will not be poisoned. Therefore, the control of emissions of tetrachlorethylene and human intake is the key to ensuring safety.
 

 
On the open-type dry-cleaning machine, the structure of the decision must have exhaust emissions, then in order to ensure that the operator, equipment, clothing clothes should be negative at the mouth, to avoid tetrafluoroethylene gas overflow from the charge port. Dry cleaning machine standard also made a clear: "open-type dry cleaning machine should have a safety interlock device. Loading door does not close, the machine can not start; open the loading door, the fan should automatically start; close the loading door, fan Automatic stop ". On the whole closed dry cleaning machine, because the door is no ventilation, the operator can still smell the smell, still can not eliminate its harm, therefore, the new dry cleaning machine has been improved, different manufacturers to take different measures. There are some manufacturers of dry cleaning machine with a boot process can not open the loading door of the interlock, to avoid misuse caused by accidental injury.
 
 
Dry cleaning machine noise is generally much lower than the environmental limit, the standard provisions of not more than 80dB (A), how to reduce noise is not only a design and manufacturing problems, but also largely subject to the quality of the kit, for large dry cleaning machines, noise Control or can not be ignored. In order to prevent accidental mechanical damage, the standard provides "in the rotation of the belt and shaft, etc. should be added rigid shield", although this is a design common sense, but it is necessary to be emphasized. In particular, users in the maintenance of the machine, be sure to install a protective cover. For the protective cover requirements, not only is the rigid, but also should be careful to ensure that can not be accidentally into the fingers.
 
 
In general, the dry cleaners in the use of tetrachlorethylene dry cleaning equipment, the best choice of fully enclosed, try to avoid the personal clothing, bed sheets, quilt, etc. for dry cleaning, if dry cleaning needs dry cleaning, dry cleaning found a heavy Pungent odor, it may be due to the residual residue on the clothes caused by tetrachlorethylene. Because tetrachlorethylene is a highly volatile substance, consumers can take the clothes from the dry cleaners, the clothes hanging in the place of ventilation and more drying for some time, so that after evaporation of tetrachlorethylene and then wear. To ensure that tetrachlorethylene has a poisonous object to play a failure, not for people to bring health risks.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
