Cleaning and maintenance: a large inventory of cleaning carpets and cleaning methods

Most carpets are made from raw materials such as wool, hemp, cotton, various chemical fibers, blended fabrics, and nylon. After use, the tea stains, coffee, oil stains, beverages, and dust on the carpet not only affect the aesthetic effect, but also shorten the carpet. The service life. Application of professional technology, with professional equipment and carpet cleaners to clean and dry carpets, not only can completely remove stubborn stains on the carpet, and make the carpet clean and soft, flexible, bright as new. Most of the dirt on carpets can be cleaned with carpet cleaners and carpet cleaners.
1, for stubborn dirt can be cleaned as follows:
(1) Solubility in water-soluble stubborn dirt: It can be cleaned by rubbing with the carpet cleaner liquid.
(2) Oily stubborn dirt: It can be cleaned locally with a solvent-based cleaner.
(3) Obstinate dirt on proteins: It can be rubbed with carpet cleaner liquid.
(4) For stains such as blood stains, bleaching fluid can be used.
2, regular cleaning optional water pumping method to clean the carpet (can be suitable for chemical fiber carpet) Use of equipment: carpet cleaning machines, hair dryers and so on.
The use of materials: MG102 low foam carpet cleaner / MG103 dry foam carpet cleaner / MG106 carpet stain remover / MG909 carpet mildew fungicides / MG123 Jierou high foam carpet water.
US high cleaning equipment (carpet maintenance series: M1301 mute carpet washing machine / M1303 carpet stain cleaning machine / M1304 sofa machine / M1305B triple carpet washing machine / M1501 timing three-speed hair dryer / M1502 three-speed hair dryer), generally Operation method:
1, vacuum cleaner;
2, diluted detergent, can also be injected into the water tank;
3, spray the cleaner on the carpet;
4, after 10-15 minutes of action, the stain is removed from the fiber;
5. Wash with a floor scrubber. Operate backwards so that each operation line has a part of overlap. At least two times of purging are performed. At the same time when carpet is cleaned, the washed carpet is sucked with a suction machine.
6. Finally dry the cleaned carpet with a three-speed blower.

Chlorine dioxide when used as an effective disinfectant forms undesirable disinfection by-products, i.e. chlorite and chlorate ions. The aim of this research was to study the removal of these ions byferrous ions in the presence or absence of oxygen. The efficiency of Fe+2 for ClO2- and ClO3- removal was followed by a determination of their initial and final concentrations, pH and delta Fe+2 consumed/delta ClO2- removed ratios. The optimal weight ratio of delta Fe+2 consumed/delta ClO2- removed for complete ClO2 removal was found to be close to the theoretical calculated value of 3.31. It was proved that ferrous salts can reduce chlorite ions to harmless Cl- ions. This method can be recommended as a part of ClO2 disinfection to ensure safe drinking water, with no harm to waterconsumers and to the environment.
