Know "mineral oil"

According to the custom, the base oil extracted from oil by physical distillation method is called mineral oil. The processing flow is that after the crude oil is refined, the residual bottom oil is refined after fractionation of useful light substances. It is called the old three sets (solvent refining, ketone benzene dewaxing, white clay supplement refining)). The two main steps are solvent refining to remove non-ideal components such as aromatics and solvent dewaxing to ensure low temperature fluidity of the base oil. The production process is mainly based on physical processes and does not change the structure of hydrocarbons. The base oil produced depends on the content and properties of the ideal components in the raw materials. Because the mineral oil cannot be removed in the refining process, the flow point Higher, not suitable for use in cold belts; therefore, mineral oil base oils are limited in their properties.

Mineral oil uses ancient animal debris as a carrier, absorbs the essence of the world, and is dedicated to nature's human-usable substances.

characteristic

Its intuitive appearance is: lustrous, bright, and natural harmless to human beings; the internal potential is: there is a desire to burn, explosive, and organic combination of the material will become a powerful material.

ingredient

Mineral oils mainly contain hydrocarbons with relatively few carbon atoms, many with dozens of carbon atoms, and most are unsaturated hydrocarbons, ie hydrocarbons containing a carbon-carbon double bond or a hydrazine bond.

Refining method

Mineral oil is a light oil distillate from 250 to 400°C in crude oil. It is obtained by acid-alkali refining, water washing, drying, clay adsorption, and addition of antioxidants. Paraffin-based crude oil should also be dewaxed. In order to reduce the freezing point of the insulating oil, an appropriate amount of pour point depressant may be added. Take different distillates in crude oil, and control the concentration, dosage, action time and other related technologies of the refinery, obtain transformer oil, capacitor oil, cable oil, switch oil, etc. with different uses. It is also possible to use solvent refining or solvent refining in combination with hydrotreating instead of acid-base refining. Mineral oils should be controlled at an appropriate refining depth. Insufficient refining does not remove harmful impurities from the oil; over-refining, however, removes too much of the natural antioxidants and aromatics contained in the oil and reduces its stability and gettering properties. This has a particular effect on cable oils and capacitor oils. . For the switch oil in order to improve its arc extinguishing ability, the content of aromatic hydrocarbons in the oil should be reduced as much as possible.

White oil type

Some areas of mineral oil called white mineral oil or white oil, commonly used industrial grade white oil, cosmetics grade white oil, medical grade white oil, food grade white oil. Different types of white oils also differ in their use.

The industrial white oil grade white oil is obtained from the hydrocracking production base oil, and is obtained after deep dewaxing, chemical refining and other processes, and can be used for chemical, textile, chemical fiber, petrochemical, power, agriculture, etc. PE, PS, PU and other production.

Food-grade white oil is mineral oil-based oil, which is obtained through deep chemical refining and edible alcohol extraction. Applicable to the lubrication of processing equipment for food industry such as grain and oil processing, fruit and vegetable processing, dairy product processing, bread cutting machine, etc., applied to food polishing, anti-adhesion, defoaming, planing, sealing, can be used as macaroni, bread The release agent for foods such as biscuits, chocolates, etc. can prolong the storage and freshness of wine, vinegar, fruits, vegetables and canned goods.

Medical-grade white oil, suitable for the pharmaceutical industry, can be used as a detoxifying agent for the production of laxatives and anti-foaming agents for the production of penicillin.

Make-up grade white oil is obtained after deep purification using hydrogenation raw materials. Applicable to the cosmetic industry, can be used as base oil for hair creams, hair oils, lipsticks, face oils, skin care oils, suntan lotions, baby oils, and vanishing creams.

Make-up grade white oil can be used as an anti-static agent, emollient, solvent, solvent, hydrocarbon, can increase the moist feeling, but can not directly improve the dry and damaged skin. There are many opinions about whether mineral oil harms the skin, but it is certain that impure can cause allergies and acne-proneness, and those who are already injured or sensitive to skin should avoid it. Because of its color and characteristics, it is often used in white cream medicines or skin care products.

The higher the mineral oil grade, the better the purity and the safer to the skin. However, it can't be distinguished by smell, look, or touch, and it must be professionally tested.

In the pesticide industry: can be used to control insect pests of citrus tree borers, rust ticks, scale insects, eucalyptus and red bayberry. After processing, it is a good insecticide, and its mechanism of action is through the closing of the pores of adults or larvae, resulting in asphyxiation. Especially for ticks, cockroaches, whiteflies, scale insects and other minor pests, the effect is very good, and the price is low. It can be processed into emulsifiable concentrates and can be used on site. Because of its unique formation of the oil film to seal the pores of pests and kill them by physiology, long-term use without resistance. Does not cause harm to natural enemies, thereby reducing the cost of medication. Long-term use without residue, can be naturally decomposed into water and easily degradable, does not cause residues on crops.
