What is the proportion of disinfectant What is the ratio of disinfectant?

84 disinfectantand clean water according to the ratio of :100 can be used to configure disinfectant water.

The disinfectant mainly refers to the 84 disinfectant, which contains a certain amount of chlorine, because it needs to be diluted with water on the basis to keep the disinfectant between 250 and 500mg l. If you want to get a disinfectant with a concentration of 252mg l of effective chlorine, you need to dilute it with 5ml of 84 disinfectant solution and 1000ml of water, and the corresponding concentration can be obtained.

Disinfection method

1.Physical disinfection: It is the use of physical factors to kill or eliminate pathogenic microorganisms.

and other harmful microorganisms. It is mainly used to disinfect items. For example, use heat to cook, bake, disinfect and sterilize; It can also be irradiated with ultraviolet light, which is mostly used for disinfection of air and clothing; Washing the surface with soapy water can eliminate more than 90% of bacteria.

2.Chemical disinfection: A method of disinfection with chemicals. For example, with alcohol or iodine.

Iodophor wipes the ** or wound to achieve the effect of disinfection. For the disinfection of items, a certain concentration of chlorine-containing disinfectant can be used to wipe it, and the disinfectant has bleaching powder, lysol solution, etc. Ethylene oxide can also be used.

Glutaraldehyde sterilizes instruments.

The criteria are as follows:Configuration of disinfectant: 84 disinfectant solution and distilled water in 1:

The ratio of 1 is proportioned, that is, 1ml of 84 disinfectant is added to 1ml of water, and after being fully mixed, it can be used for disinfection of items, remember not to add other disinfectants.

2. Configuration of effervescent tablets containing chlorine: 1ml of water needs to be added to a 5 mg chlorine-containing disinfection tablet, and after the tablet is completely dissolved, stir and mix well.

3. Configuration of chlorine-containing disinfection powder: weigh 1g of disinfection powder, then add 11ml of water, mix and stir well for disinfection.

Generally, disinfectants need to be diluted with water before use, but the specific dilution ratio should be calculated according to the type of disinfectant and the place where it is used.

For example, oxytech Octex disinfectant is diluted at a ratio of 1:100 for indoor spray disinfection and clothing disinfection in ordinary households, and 1:1000 for plant and flower sterilization.

If it is sterilized in some pharmaceutical clean areas and food purification workshops, the proportion should be higher, and it should be diluted according to the ratio of 1:50.

As follows:

1. For indoor doors and windows, door handles, countertops, faucets, indoor floors with frequent personnel activities, and surfaces with frequent public contact, use 500mg l 1000mg l chlorine-containing disinfectant to spray or wipe and disinfect, and the frequency is determined according to the situation of personnel exchanges.

2. For the preventive disinfection of towels and tableware, use 250mg l 500mg l chlorine-containing disinfectant to soak and disinfect for 30 minutes and then clean, or boil or steam disinfection for 30 minutes, and the frequency is determined according to the situation of personnel exchanges.

3. Garbage bins (pools) and garbage heaps: garbage should be cleaned daily, sprayed with 1000mg L of chlorine-containing disinfectant, and sprayed twice a day in the morning and evening.

Disinfector (commonly known as disinfectant, disinfectant) is a liquid disinfectant, which is mainly used for disinfection work in various places and requirements to kill bacteria, fungi, viruses and other microorganisms.

According to the different places of use, disinfectants can be divided into household disinfectants, industrial-grade disinfectants, food-grade disinfectants, etc., according to the chemical composition of sodium hypochlorite (84 disinfectant), quaternary ammonium salt (94 disinfectant), chloro-m-xylenol (Dettol disinfectant, Velux disinfectant), peracetic acid, etc.

Take 5% 84 disinfectant as an example, each liter of disinfectant contains 50 grams of effective chlorine, and the instructions require 100 times dilution, that is, 99 parts of water should be added to 1 part of disinfectant, and the concentration is 500mg l before it can be used.

In order to facilitate the preparation, the cap capacity of 84 disinfectant is about 10 ml, you can use the bottle cap as a measuring cup, wear rubber gloves to add a cap of 84 disinfectant to the basin, and then put 1000 ml of water, you can also fill a 500 ml bottle with water, pour two bottles, stir and mix. After 30 minutes of action, wipe with water.

Disinfectant preparation.

Commonly used configuration unit: mg l, Chinese means milligram liter, is how many milligrams of solute is dissolved in a liter of solvent, such as 300mg l, which means that there are 300 mg of active ingredients (solute) in a liter of disinfectant (solution). Note:

1 gram = 1000 mg.

PPM is the abbreviation of English partspermillion, which translates to a part of per million, that is, the parts per million (several), or parts per million. For example, 100 ppm, that is, one million kilograms of solution, contains 100 kilograms of solute. ppm is the same as the percentage (%), except that the proportion is greater than the percentage.

<> the proportion of disinfectant water will change according to the concentration, generally when disinfecting fruits and vegetables and tableware, you can soak and wash the disinfectant and water in a ratio of 1:200, which can effectively eliminate the bacteria on the tableware. If the fruits and vegetables have already been washed once, you can use 1:

250 ratio, so that the concentration will be lower.

Generally, indoor disinfection and cleaning can be mixed with disinfectant and water in a ratio of 1:100, which can be sprayed indoors for disinfection, or wiped with a clean rag and wiped after wiping the indoor furniture. Since disinfectant is corrosive and has a pungent odor, it is necessary to open the window to breathe after wiping and spraying.

When disinfecting medical supplies and toilets, such places that need to be efficiently disinfected, the ratio of disinfectant to water is best adjusted according to the method of 1:50, and the concentration of disinfectant is appropriately increased to enhance the ability of disinfection and sterilization. However, when preparing disinfectant, wear plastic gloves to avoid corrosion**.

The ratio of disinfectant is mainly as follows:1. Disinfect indoor doors, windows, and door handles, 500mg l 1000mg l;

2. Preventive disinfection of towels and tableware, 250mg l 500mg l;

3. Garbage bin disinfection, 1000mg l.

Disinfectants are classified according to their disinfection effect(1) High-efficiency disinfectant:

It refers to the preparation that can kill all bacterial propagules (including mycobacteria), viruses, fungi and their spores, etc., and also has a certain killing effect on bacterial spores (pathogenic spores) and meets the requirements of high-level disinfection.

2) Medium-acting disinfectant:

It refers to the preparation that can kill microorganisms such as mycobacteria, fungi, viruses, and bacterial propagules to meet the disinfection requirements.

3) Inefficient disinfectants:

It refers to the preparation that can kill bacterial propagules and lipophilic viruses and meet the disinfection requirements.

500mg l chlorine-containing disinfectant: 84 disinfectant with a concentration value of 5% is configured at 1:99, and 84 disinfectant with a concentration value of 11% is configured at 1:

219 configuration, used for disinfection and sterilization of dining utensils. 100mg l chlorine-containing disinfectant: 5% concentration value 84 disinfectant press 1:

49 configuration, 11% concentration value 84 disinfectant according to 1:109 configuration, etc., used for disinfection and sterilization of general object surfaces.

Ethanol: 500 ml of 95% ethanol, add water to obtain 75% ethanol. Fill with 95% ethanol and add 666ml of water to obtain 75% ethanol.

Note: Disinfectants should be stored in a dark, cool place. Each disinfectant is configured and applied independently, and when configuring and using, wear work clothes, water boots, long rubber gloves, and protective masks.
