Ask for help in the use of alkaline lipase in the washing industry!!!

Alkaline lipase is a lipase hydrolyzed under alkaline conditions, and the main raw materials for the production are wheat, corn and other agricultural and sideline products, which are transformed by biological fermentation technology. It can hydrolyze natural oils and fats to produce fatty acids and glycerol, and is an enzyme that specializes in the hydrolysis of special esters at the oil-water interface of heterogeneous systems.

Alkaline lipase is a new type of enzyme for detergents, and its main use is as a new enzyme for detergents. Its characteristic property is to decompose clothing oil into water-soluble substances such as diglycerides, monoglycerides and fatty acids, thereby significantly improving the washing effect of laundry detergent, especially the macular removal effect. We commonly use a variety of enzyme-containing laundry detergents, among which the enzyme preparations mainly include alkaline protease and alkaline lipase.

Alkaline protease is used to decompose protein-like dirt, such as sweat stains, blood stains, etc. Alkaline lipase mainly acts on fatty acids and their ester contaminants, which are commonly referred to as oil stains.

Adding enzymes to detergents can improve the detergent ability, reduce the amount of surfactant and sodium tripolyphosphate, make the detergent develop in the direction of low phosphorus or no phosphorus, reduce environmental pollution, and play a new function of washing. As a biological product, enzymes are non-toxic and can be completely biodegradable, and play a benign role in the ecological balance of the environment. At the beginning of the 20th century, some people have begun to try to use animal enzymes for fabric washing to remove dirt, such as Germany's Rohm used enzymes in soap, but they all failed due to poor enzyme stability and stability; In the 50s, Switzerland and the United States carried out the research and trial production of the first microbial detergent enzyme, and the alkali resistance of the enzyme was improved; In the early 60s, the alkaline and heat-resistant protease was successfully trial-produced, and the enzyme was officially used in the formulation of synthetic detergents.

The application of lipase needs to comprehensively consider the following factors: 1. What is the content of fat in the feed? 2. What is the digestibility of fat in feed?

3. Is there a relative lack of lipase in animals? When is it relatively lacking? 4. Are the enzymatic properties of lipase suitable for feed processing and animal environmental conditions?

I'm here just to make a suggestion. I think that for recent graduates, the most lacking thing should be experience, so I think learning is still the most important, and you can guess while looking for some projects that suit you

My advice is to give yourself more opportunities to learn from others! And take advantage of some passing opportunities! ~

Lipases are generally acidic. The basic unit of lipase is only amino acids, usually with only one polypeptide chain. Its catalytic activity is determined only by its protein structure.

If you are using an enzyme-containing laundry detergent, it is better to use warm water. Otherwise, it doesn't make much difference except for the feel.

Hello! Because the clothing has a certain temperature tolerance range, some clothing materials are not resistant to high temperatures, and it is not suitable to use hot water soaking, such as woolen sweaters will shrink when washed in water higher than 30; In addition, dark clothes are prone to fading, and hot water will aggravate the fading, so it is recommended not to use hot water to soak, but to soak in cold water or room temperature water.

25 40 degrees of warm water is the best, hot water is easy to hurt the clothes, damage the fabric structure, such as deformation, discoloration, fading, etc. Moreover, some fabrics are added with some chemicals in the dyeing process, and the high temperature is easy to make it chemically react, and when you wash your clothes, you should look at the range of heat resistance on the label on your washed clothes and the instructions on the detergent. Hehe.

It's good for most clothes.

Answer: Hello, here you are a life consultant, your question has been received, here is integrating the answer for you, and you will reply within five minutes, please don't be in a hurry and wait patiently.

Hello, dear, I am your life consultant, Yingying, about your questions, I will integrate the answers for you

Dear, about your question, washing clothes and laundry without water, here is the answer for you

Washing clothes and washing clothes, you can guess by looking at the word washing in front of you, it is something that requires water to achieve

Of course, water is absolutely necessary for normal laundry, but in special cases, there may be no need to pour water, such as sending it to a dry cleaner, because some clothes are inconvenient to wash and rub with a large amount of water, so the dry cleaner will use a special method to wash, but even so, a small amount of water will be used

Therefore, washing clothes is inseparable from water.

Question: Hello, I added a lot of water to the washing machine box, okay!

Thank you and have a great day and goodbye [flowers].

Kiss, it's okay.

The washing machine has a self-draining yo.

If your laundry box does not have a drain function, it is recommended that you report it as it may eject when washing

Question: Does the washing machine put water in the laundry?

Question: Can a faucet represent water and provide water to the washing machine?

If you turn on the faucet switch and the washing machine, it will automatically put water into the washing machine.

Question: I've added a lot of laundry detergent to my box, okay? Do I need to add water to the laundry head when I open it?

If it's not very exaggerated, like half a bucket, you generally don't need to add extra water, if you are not at ease, you can increase the amount of water in your washing machine

Or if you are worried that there is too much laundry detergent and you don't wash it clean, it is recommended that you wash it twice.

If you are halfway to the bottle, you can add more water, but it will not have much effect

That's a lot of questions! Do I need to add water to the laundry head when I open it?

The washing machine can control the amount of water, oh, you don't need to add extra ha.

Question: Is adding more water by yourself? Or what?

That is, the washing machine has a program setting, it will set how much water you need to wash clothes this time, and how much water you can adjust in that place

Hello! Because the clothing has a certain temperature tolerance range, some clothing materials are not resistant to high temperatures, and should not be washed with high-temperature water, such as woolen sweaters will shrink when washed in water higher than 30; In addition to water, inorganic salts, urea, sweat stains also contain lactic acid, fatty acids and a variety of amino acids. In addition, dark clothes are prone to fading, and hot water will aggravate the fading, so it is recommended not to use high-temperature water, but to wash with cold water or room temperature water.

Some clothes cannot be washed with hot water, such as woolen sweaters, and cotton ones are not suitable for washing with hot water, and these two kinds of clothes are easy to shrink when washed with hot water. If the blood stains on the clothes can not be washed with hot water, because the blood stains will solidify in the hot water, the oil stains on the washing clothes are better washed with hot water The most suitable temperature is 20 30, not more than 50 degrees, especially the laundry detergent with enzymes, because the enzyme is a protein, the activity is strongest in twenty or thirty degrees, and the temperature is too high to lose its activity.

To choose the temperature of the water according to the material of the clothes, it is best to use warm water to wash the clothes.

In summer, the human body loves to sweat, so you can't use hot water, because hot water will chemically react with sweat stains (which contain salt) and cause clothes to turn yellow. I never wash my clothes in the summer. It's okay to wash it with warm water in winter.

Deal with different stains and different temperatures

Hot water in winter and cold water in summer.

Answer D: Enzyme laundry detergent refers to laundry detergent containing enzyme preparations, and there are four types of commonly used enzyme preparations: protease, lipase, amylase and cellulase.

Among them, the most widely used are alkaline protein vertical grip enzyme and alkaline lipase. The wool itself is mainly composed of proteins and cannot be washed with enzymatic laundry detergent. The activity of enzymes is affected by temperature, and too high a temperature can easily inactivate enzymes; Low temperature will not inactivate the enzyme, only the activity will be inhibited.

The washing effect of alkaline protease is the best, but the alkali and enzyme in it are corrosive to **, so be sure to rinse your hands with water in time after use.

There are four categories of surfactants, such as anical, ano, non-and hand-washed zwitterion, but they are mainly anionic and nonionic for washing The most common and traditional anionic surfactant is the soap (sodium of advanced fatty acids) that has been used for hundreds of years After the advent of the synthetic washing industry, the most commonly used is sodium p-dodecylbenzene sulfonate (LAS), and the most widely used nonionic surfactant is polyoxyethylene ether In recent years, the performance of anionic-nonionic composite surfactants with difunctional groups is more comprehensive. Such as Bijan sulfate with polyoxyethylene ether chain, fatty acid salt with polyoxyethylene ether, etc
