How to make antifreeze glass water for cars?

1. When making antifreeze glass water, prepare distilled water, neutral washing spirit and industrial alcohol, and then add 75% concentration of alcohol to the distilled water, and then add a drop of washing spirit and mix well. If there is no medical alcohol, you can use white wine to prepare it.

2. To make the freezing point reach -25 degrees, 35% methanol and 65% water can be used to test the calculation formula of the freezing point of methanol aqueous solution. △Tf=Kf·bB or △Tf=Kf·m/ (MB·MA) This formula can be used to calculate the amount of methanol at each freezing point of methanol solution. You can make a freezing point curve by yourself.

3. It should be mixed according to the proportion of the formula. If the glass tank cannot be filled, pure water can be added. Note that the glass water should not be filled too much, and it should reach or be lower than the marked ruler. Considering the low temperature in winter, homemade glass water is likely to fail to achieve the antifreeze effect of professional glass water, so it is recommended to buy regular high-quality glass water.

4. Production and usage instructions Make according to this formulaAntifreeze glass water is very simple. You just need to mix alcohol, detergent and water in a ratio of 1:2:3. When using, pour homemade antifreeze glass water into the glass water storage tank of the car, and then you can use it like ordinary glass water.

5. Material: concentrated wiper essence effervescent tablets, pure water, alcohol. The preparation method: according to the instructions of concentrated wiper essence effervescent tablets, a piece can be made into 2-4 liters of glass water, and 3 liters can be directly. First, pour 3 liters of pure water into a large bottle and add effervescent tablets. When the effervescent tablets meet water, they will slowly dissolve. Add about 600ml of alcohol during this period.

What is the formula and production method of automobile antifreeze

Production: Mix ethylene glycol and water together in a ratio of 1:5 (mass ratio), add an appropriate amount of disodium hydrogen phosphate, and add a little sky-blue pigment.

The formula for making antifreeze is as follows: material preparation: water (softened water or distilled water), ethylene glycol, disodium hydrogen phosphate, sky blue raw materials, etc. Ethylene glycol and water are mixed together in a mass ratio of 1:5. The water is distilled water, softened water or boiled water, and tap water cannot be added directly.

Production method: Mix ethylene glycol and water together in a ratio of 1:5 (mass ratio), add an appropriate amount of disodium hydrogen phosphate, and add a little sky blue pigment.

Automotive Paint Coloring Formula Collection

1. Query the formula: Find the formula from the computer software and calculate the amount of color master through Yang.

2. The paint coloring formula is as follows: red + yellow = orange - less yellow + more red = dark orange - less red + more yellow = light yellow. Red + blue = purple - less blue + more red = purple + more red = rose red. Yellow + blue = green - less yellow + more blue = dark blue - less blue + more yellow = light green. Red + yellow + less blue = brown - red + yellow + blue = gray and black.

3. There is no simple formula for car paint matching.You can remember that paint mixing requires rich experience and a suitable environment. However, you can refer to the following basic color and color cards of car paint color. Red and yellow turn into orange... Yellow decreases, red increases, orange deepens... Red becomes less, yellow becomes more, and yellow becomes lighter.

4. Gray paint is white and black mixed evenly, and the specific proportion can be determined by yourself. If it is light gray, you should add more white than black, and slowly add black to the gray paint until the color is suitable.

What is the formula of automobile brake fluid?

Hemp oil alcohol type, formulated with refined castor oil and ethanol at 1 to 1. Synthetic type, made of ether, alcohol, ester and other additives mixed with lubrication, anti-rust, anti-rubber swelling and so on.Mineral oil type is made of refined light diesel fractions with thickeners and other additives.

There are three types of brake fluid: 1 castor oil-alcohol type: it is formulated with refined castor oil and ethanol at 1:1. In cold areas, the brake fluid made of 34% castor oil, 13% propylene glycol (glycerin) and 53% ethanol can still ensure normal braking around -35[oc], but the boiling point is low and it is easy to produce gas resistance.

There are three types of brake fluid: castor oil-alcohol type: It is made of refined castor oil 45%-55% and low-carbon alcohol (ethanol or butanol) 55%-45%. After precipitation, a colorless or light yellow clear and transparent liquid is obtained, that is, alcohol-type car brake fluid.

There are 3 kinds of brake fluid, which are: castor oil alcohol type: made of refined castor oil and low-carbon alcohol;Synthetic type: made of ether, alcohol and ester mixed with lubricating, antioxidant, anti-rust and anti-rubber swelling additives; mineral oil type: made of refined light diesel fractions with thickener.

vehine antifreeze formula

1. Commonly used are triethanolamine, benzotriazole, benzothiazole and organic phosphate ester, which have good corrosion inhibition performance. Antifoamer: When the car is driving, due to the beating and vibration of the car body, the air seeps into the antifreeze to produce foam.

2. Automotive antifreeze formula, - weight ratio, the percentage of each component is: deionized water 30-65%, ethylene glycol 30-60%, nonoctyl dioctyl ester 1-10%, diglycol monomethyl ether 1-10%, sodium tripolyphosphate 0.2-0.3%, potassium polyphosphate 0.4%.

3. The high-quality coolant is made of distilled water and an anti-scale additive is added, which not only does not produce scale, but also has the function of descaling. Of course, if your water tank is very thick, you'd better clean it thoroughly with water tank cleaner before adding coolant.

4. In the south of the Yangtze River in China, a ratio of 40% mass fraction of ethylene glycol is generally adopted, while in the cold north, it is more appropriate to take a ratio of about 50% of the mass fraction of ethylene glycol.

5. Sugar, honey, etc., this is a common car antifreeze in daily life. It can be used as the mother liquor of antifreeze. After adding an appropriate amount of pure soft water, it can become an antifreeze in the general sense.

What is the formula of automotive antifreeze

1. The ingredients of automotive antifreeze are ethylene glycol, propylene glycol and diglycol, silicate, etc.Antifreeze is the full name of antifreeze coolant. Antifreeze is a coolant containing special additives, which is mainly used for liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreeze in winter, anti-boiling in summer, anti-scale, anti-corrosion throughout the year.

2. [Pacific Automobile Network] Automobile antifreeze is composed of freezing reducer, corrosion inhibitor, defoamer, colorant, mold inhibitor and buffer.

3. What are the formulas? Automobile antifreeze formula, - weight ratio, the percentage of each component is: deionized water 30-65%, ethylene glycol 30-60%, nonodiol dioctate 1-10%, diglycol monomethyl ether 1-10%, sodium tripolyphosphate 0.2-0.3%, potassium polyphosphate 0.4%.
