According to the boiling range, solvent oil can be divided into three categories: low boiling point solvent oil, such as 6 extraction solvent oil, boiling range of 60-90; Medium boiling point solvent oil, such as rubber solvent oil, the boiling range is 80-120; High boiling point solvent oil, such as paint solvent oil, has a boiling range of 140-200, and the dry point of ink solvent oil, which has been widely used in recent years, can be as high as 300. In general, 60 90 is called extracted solvent oil, that is, people often say 6 solvent oil; 80 120 is called rubber solvent oil, that is, people often say 120 solvent oil; 140 200 is called paint solvent oil, i.e. 200 solvent oil.
In addition, there are ink solvent oils, dry cleaning solvent oils, etc. Sometimes, the cutting of the distillation process will also vary from business to enterprise. For example, 6 solvent oil, some manufacturers have a distillation range of 60 75, usually we call it narrow 6 solvent oil, to show the difference.
According to the actual production, the distillation range of 120 solvent oil is often controlled between 90 and 120.
According to the chemical structure, solvent oil can be divided into three types: paraffins, naphthenes and aromatic hydrocarbons. In fact, with the exception of a few pure hydrocarbon compounds such as ethane, toluene, and xylene, solvent oils are mixtures of various structural hydrocarbons. In terms of chemical composition, it can be divided into paraffins, naphthenes and aromatic hydrocarbons.
Commonly known as solvent oil, it is paraffin. Aromatic hydrocarbons refer to benzene, toluene, xylene, etc.

The main component of GB 200 is alkanes. There are trace amounts of olefins and small amounts of aromatic hydrocarbons.
The raw materials used to produce the national standard No. 200 are different, and the ingredients vary greatly.
The national standard No. 200 produced by the reformer pumping residual oil is mainly naphthenes, density.
The national standard No. 200 produced with naphtha or DC gasoline and condensate is mainly a straight-chain alkane with density. So, the density of number 200:

ABS plastic is a terpolymer composed of butadiene-acrylonitrile-styrene, commonly known as ABS plastic, its critical surface tension is 34-38mn cm, heat deflection temperature is 70-107, the solvents that can dissolve ABS plastics are ketones, benzene and ester solvents, and alcohol and hydrocarbon solvents have no dissolution effect on ABS plastics, so the selected ABS special coatings should generally contain an appropriate amount of the above solvents and non-solvents. ABS plastic has a wide range of coating options, mainly thermoplastic acrylic coatings, as well as epoxy alkyd nitro paints, etc., the following is an example of a special coating resin for ABS plastics. Acrylic resin composition:
Methyl methacrylate 40%-45% methacrylic acid 2% butyl methacrylate 35%-40% benzoyl peroxide 2%-5% hydroxyethyl acrylate 20% azodiisobutyronitrile 1%-2% Solvent composition: toluene, xylene 50 parts 200 solvent gasoline 20 parts butyl acetate 30 parts.

Good afternoon, the main raw material of alcohol-based fuel is methanol, the hydrocarbon part is 6 or 200 solvent oil and gasoline, the two mutual solvents are EGBE (ethylene glycol butyl ether), and the octane booster is EHNA (isooctyl nitrate, which can also be omitted), which is the basic formula of general alcohol-based oil, and the main reason for improving its combustion calorific value is to replace it with a more effective octane booster, and you can add tetraethyl lead or tetraethyltin if possible, but in terms of performance, the alcohol base is not as good as gasoline no matter how it is modified. Please refer to it and be aware of it.

Crude methanol, the main raw material of alcohol-based fuel, alcohol-based fuel is a hot spot for the development of today's civil fuel, and the promotion of this technology has attracted great attention from relevant ministries and commissions of the state. At present, the alcohol-based fuel of the country is mainly used in the cooker, but there are many problems in the development of the alcohol-based fuel and the cooker at present, such as the complex fuel formulation, the implementation of a unified standard, a large amount of water and some harmful substances in the fuel.
There are currently three types of alcohol-based fuels:
Alcohol-water fuels. That is, the fuel contains more than 20% water. Methanol fuel already has a low calorific value, which, combined with water, makes the fuel even lower.
Many units engaged in alcohol water fuel claim that adding water to alcohol, and adding a certain catalyst can make water split, produce hydrogen and increase the calorific value. This is a wrong concept that violates scientific principles, so so far, we have seen that the use effect of alcohol-based fuels is very poor, and the calorific value cannot meet the technical requirements of the industry standard of "alcohol-based civil fuels", and the gasification effect of the stove using this alcohol-water fuel is not good, and the structure design of the stove is complex. We don't think this fuel can be promoted.
Alcohol-based fuels. This fuel mainly adds 10% hydrocarbons to crude methanol to increase the calorific value of the fuel. Due to the addition of hydrocarbons, it is easy to stratify alcohol-based fuels during storage and use, and appropriate addition of co-solvents makes alcohol-based fuels and hydrocarbons evenly mixed without stratification.
At present, this fuel is used more, but the promotion of this fuel must control the formula of the fuel, and it is best to not exceed 3 yuan (excluding water) of the combination of fuel formula, that is, methanol - co-solvent - hydrocarbons. It is strictly forbidden to add harmful organic chemical products as additives, which complicate the formulation. At the same time, it is best to control the water content not to exceed 10%, and the hydrocarbon content should be suitable for the cooker.
Alcohol ether fuels. Alcohol ether fuel technology is mainly developed by the Southwest Research Institute of Chemical Industry of the Ministry of Chemical Industry, the characteristics of this fuel is that most of the dimethyl ether is dissolved in methanol and water, and at the same time, the pressure required for the raw material is generated by the dimethyl ether in the cylinder, so as to avoid the existing alcohol water, alcohol hydrocarbon fuel in the ignition process need to be preheated and pressurized, is a promising fuel. However, due to the high cost of dimethyl ether, the difficulty of storage, and the fact that the fuel contains more water, it is difficult to produce supporting stove fuel, so it is difficult to promote it now.
We believe that alcohol-based fuels should now promote the second alcohol-based fuel, and with the improvement of people's living standards, the gradual promotion of alcohol-based ether-type fuels with lower water content.
