The washing powder is the daily necessities, and everyone should be used, and washing powder related issues not only relates to the washing effect, but also the health and environmental protection, to understand some common sense can play a multiplier effect of the washing powder is the daily necessities, and everyone should be used. However, such a common washing supplies, but not everyone is good. And laundry detergent related issues related to the washing effect, but also related to health and environmental protection. Therefore, it is necessary in the choice of washing powder to stay in mind, but also to grasp some "tricks" when use, so can you.

Add enzyme washing powder can not be washed silk
Common problems: to remove grease, stains, rust, paint and other stains difficult to wash, how to choose the washing powder?
Answer: for specific stains, washing powder in the usually add protease, amylase, lipase, cellulase to strengthen the washing effect. Protease catalyzed hydrolysis of meat stains, stains, milk stains, blood stains and other dirt; amylase can catalyze the hydrolysis of chocolate, Mashed Potato, Steamed Rice dirt; lipase can decompose all kinds of animal fats and human sebaceous secretions can remove dirt; cellulose fiber protrusion on the surface of the fabric, clothing to protect color, soft, refurbishments. The original use of a single protease, and now the general use of compound enzymes. Blue or red powder, such as washing powder particles is the enzyme. Some enterprises to use the quality of enzyme and weight of the enzyme, the impact of the washing effect, so consumers still have to choose well-known brands of washing powder. Rust stains and pigments, dye removal requires a certain condition, washing is difficult, it is best to send to the laundry treatment. Consumers should pay attention to enzyme detergent can not be used for washing silk, wool containing protein fiber fabric, because the enzyme can destroy the protein fiber structure, effects of silk, wool fabric fastness and gloss, soap or detergent available specially washed silk, wool fabric.
"Cold water quick acting" exaggerated propaganda
Frequently asked questions: some washing powder declared "cold water quick acting", with washing powder washing clothes in what temperature is the most appropriate?
Answer: "cold water available" is a violation of the laws of chemistry, there is a suspicion of exaggerated propaganda. Generally speaking, the higher the temperature, the stronger the solubility of surfactant, enzyme and assistant, the faster the decontamination. In cold water, enzymes and other active substances have not been well activated. In Europe, the default temperature of the automatic washing machine is 40 degrees C, which is the optimal temperature of the enzyme and other effective substances from the chemical reaction and solubility. China from the point of view of energy saving, automatic washing machine temperature is 30. Of course, washing temperature is too high is not good, the high temperature will cause the protein fouling, enzyme activity significantly reduced, so it is more difficult to wash.
Best choice for non phosphorus washing powder
Common problems: a lot of washing powder. "Not p" or "P" P, what harm? What is the role?
Answer: phosphorus washing powder is one of the main sources of phosphorus in the sewage pollution of life, phosphorus will lead to eutrophication, and cause water becomes turbid, massive death of fish, the eutrophication of water is not conducive to drinking. However, the addition of phosphorus in the washing powder is sodium tripolyphosphate (commonly known as the "five sodium"), calcium and magnesium ions, it can chelate water softening hard water, alkaline buffer, disperses the effects of suspended dirt and washing efficiency. Due to the national requirements "non phosphorus washing powder, widely used in enterprises at present is 4A zeolite with appropriate polymer compound or by layered silicate instead of phosphate, but phosphorus substitute chelating and synergistic effect of Sodium Tripolyphosphate on weak, and the price is more expensive than the sodium tripolyphosphate, this is also a lot of washing powder in the enterprise to continue the main reason quietly using sodium tripolyphosphate. According to incomplete statistics, China's application for the national environmental labeling certification of non phosphorus washing powder production less than 5% of the total. In order to purify our living environment, we should develop non phosphorus, non benzene compound, and no fluorescent agent.
3 minutes should be put on the net.
Common problem: "collar net" what is special? How to use it?
Answer: "collar net" products in liquid, in addition to ordinary washing active ingredients, the high content of alkaline protease, has good decomposing ability of oil, sweat, Aluminum Alloy canned product is better than the performance of the plastic products of the nozzle, because the washing liquid mist droplets can be dispersed rapidly penetrate to the surface of the clothes. However, it should be noted that the use of direct spraying on the need to wash the clothes, and then placed 3 to 5 minutes. The sprayed clothing into the water containing washing powder, the water temperature should be around 40. Because the silk and wool are protein fibers, the protease will have an impact on them, resulting in damage to the color or fiber, so the use of this kind of clothing to be careful when the collar of the collar.
Concentrated washing powder dosage less
Frequently asked questions: "high concentration", "super concentrated" washing powder, washing effect is better?
Solution: concentrated washing powder is a product that can bring convenience to consumers, the same amount of washing, concentrated washing powder can be used less, the effect of washing and ordinary products are not significantly different. Higher visibility of the brand, the production of concentrated detergent powder level is also higher.
However, the market also has a number of so-called "high concentration" of washing powder, the content of its activity is only slightly higher than the national standard requirements, is not a high concentration, high content
