In modern civilized life, people wear clothing, the use of bedding, bed linen, towel, sofa sets, curtains and so on fabric with cotton, chemical fiber, wool, silk, feather, leather and so on. How do you choose detergent after the fabric is dirty? How to clean, dry, and iron to make it clear and not damage the fabric? Saving detergent and saving time? There are many kinds of detergents, what are their characteristics? How to use it? In the use should pay attention to what issues and so many problems you can find a satisfactory answer from this article.
There are a wide variety of detergent, but the necessary ingredients are still surfactants, and then with auxiliary components such as chelating agents, anti-sedimentation agent, fluorescent brightener, enzymes and fillers.
Detergent is a kind of alkaline synthetic detergent. It has the characteristics of strong decontamination force, good solubility and convenient use.
What types of fabric detergent can be divided into?
Fabric detergent from the appearance of the product form, can be divided into solid, liquid and aerosol types. One of the solid clothing detergent can be divided into powder, granular, flaky and blocky, liquid (paste) laundry detergent according to its use or function classification can be divided into heavy scale liquid detergent, light scale liquid detergent, oxygen bleach, chlorine bleach, pre-stain agent, sizing agent and softening agent and so on. Laundry detergent, laundry cream, laundry lotion, laundry soap and soap powder are commonly used.
What types of washing powder can be divided?
⑴ according to the variety and performance of additives can be divided into phosphorus and phosphorus-free two categories.
⑵ according to the use of concentration can be divided into ordinary washing powder, concentrated detergent and so on.
⑶ According to foam can be divided into high foam detergent, washing detergent and low foam detergent and so on.
⑷ According to the functional characteristics of detergent additive can be divided into additive enzyme detergent, color bleaching detergent and so on.
What ingredients are the washing powder mainly composed of?
Washing powder is generally composed of a mixture of a variety of ingredients, of which the main washing decontamination effect of the substance is surfactant, in addition, there are some can enhance and improve the effectiveness of washing powder of substances, these substances known as auxiliaries. The types and quantities of additives to be added vary according to the different uses of detergent and the differences in dirt and fabric properties. In order to reduce costs, help molding, detergent also add fillers, such as sodium sulfate (commonly known as Glauber's).
What is the main ingredient in washing powder?
The main role in the washing powder is surfactants, which are mostly made of petroleum chemicals or oil chemicals as raw material, there are mainly alkyl benzene sulfonate, allyl sulfonate, fatty alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether sulfate and so on, they can dissolve rapidly in water, and have good solubilization, emulsifying, dispersing, foaming, Decontamination and other properties. Surfactants directly affect the quality of washing powder, so countries, although the standard is different, but the amount of surfactant added to the regulation, this is because in the detergent powder in the addition of surfactant less than a certain amount, its decontamination force can not reach the required standards.
What are the ingredients in detergent besides surfactants?
In order to reduce the cost of washing powder and further improve the comprehensive washing detergent decontamination effect, in the washing powder also added some help lotion and filler. Ordinary detergent commonly used lotion has sodium tripolyphosphate (phosphorus-free washing powder in the 4A zeolite, polymer, etc.), water-soluble sodium silicate, sodium carbonate, sodium sulfate, carboxyl methyl cellulose, fluorescent brightener and so on. In addition, in order to improve the odor of products, washing powder in general have added flavor.
Why does detergent have to add additives?
The most important ingredient in detergent is surfactants and auxiliaries. Surfactants can reduce the surface tension of water and remove stains from the fabric. However, there are usually calcium, magnesium ions in the water, they will cause surfactant precipitation and loss of washing function, adding additives mainly to solve this problem, namely: the removal of calcium, magnesium ions in water, to soften the water quality, to assist and improve the decontamination capacity of surfactants.
What are the main factors determining the quality of washing powder?
The quality of washing powder directly affects the effect of washing and decontamination. There are many factors affecting the quality of detergent, but the main factors are surfactant and the content of sodium tripolyphosphate (or zeolite). The higher the content of surfactants and sodium tripolyphosphate (or zeolite), the greater the decontamination power of the same weight detergent.
The same weight of washing powder, why some washing powder looks very full, some but very little?
The same weight of washing powder due to the performance of different densities, the volume is not the same, look more and less. The performance density can be controlled and adjusted by the manufacturer within a certain range. Ordinary washing powder performance density is low, generally in 0.28 g/cm3-0.45g/cm3, large size, looks very full, and concentrated detergent performance density, in 0.60g/㎝3 above, small size, looks very few.
is the color of washing powder whiter and better?
The whiteness of washing powder is related to the use of raw materials, raw material white will have an impact (such as: the color of the raw material itself, the type of use of whitening agent and the amount of addition, etc.); In general, the more white the washing powder the better.
is the powder agglomeration not a quality problem? What's the cause?
If the washing powder is caking by pressure, it is normal that the hand is brittle after touching. The washing powder is a kind of hollow granule, which is easily broken and caking under the condition of squeezing. If the washing powder is caused by damp or other causes caking, it is necessary to split the hand to disperse, is a quality problem. is mainly caused by excessive moisture content.
Detergent packaging on the emphasis on warm water washing, is not the effect of cold?
Washing powder in the warm water in the wash effect is better than the effect of cold waters, the solubility in the warm waters is larger, dissolved even, surfactants can play a greater effect. Still have a good effect in cold water, but relatively poor. General water temperature in 30~60℃ is advisable, not more than 60 ℃.
