Theoretically, it can be just, but in practice it is difficult to operate, depending on your own product.

Question 1: Does polyethylene glycol with water get hot? Polyethylene glycol is miscible in water, strong acids and strong alkalis become hot and dangerous when exposed to water, and polyethylene glycol will not. Hope.

Question 2: Is polyethylene glycol a water-soluble polymer compound When polymer is a polymer compound, polyethylene glycol is an alcohol substance that is soluble in water, so polyethylene glycol is a water-soluble polymer compound.

Question 3: Does polyethylene glycol contain alcohol Polyethylene glycol is a colorless, odorless, viscous liquid to a waxy solid. Soluble in water, ethanol and many other organic solvents.

The vapor pressure is low. Stable to heat. Does not work with many chemicals, does not hydrolyze, does not deteriorate.

Non-toxic, not noticeable to the eyes and**

It smells of alcohol, and most of it is mixed with alcohol.

Question 4: Is polyethylene glycol a dangerous good Polyethylene glycol, structural formula Hoch2[CH2CH2]NCH2OH or H[OCH2CH2]NOH, ethylene glycol polymer with an average molecular weight of 200-8000. With the difference of average molecular weight, the properties also vary, ranging from colorless, odorless, viscous liquids to waxy solids; The toxicity decreases with the increase of molecular weight, and polyethanol with a molecular weight of 4000-8000 is safe for humans.

The hygroscopicity of polyethylene glycol decreases with the increase of molecular weight, and polyethylene glycol 8000 has almost no hygroscopicity, but it can inhibit corrosion and absorb moisture in high humidity air.

The hydroxyl groups at both ends of polyethylene glycol have alcohol-like properties and can undergo esterification and etherification reactions. The reaction products of low molecular weight polyethylene glycol are easy to mix with oil, and the reaction products of high molecular weight polyethylene glycol tend to be water-soluble. When the polyethylene glycol is heated in the air, the oxidation of polyethylene glycol occurs, and the ether bond is broken above 300, and the larger the molecular weight, the more the tendency to be oxidized.

Stabilizers such as hydroquinone can be added to make it stable.

Polyethylene glycol is soluble in water and alcohol, esters, ethylene glycol, ether, etc., and insoluble in aliphatic hydrocarbons.

Polyethylene glycol is almost non-toxic and non-toxic.

This product is non-toxic and non-flammable, and can be handled in accordance with the general chemical transportation regulations, and stored in a dry and ventilated place to avoid sunlight and rain.

Not dangerous goods.

Question 5: Will polyethylene glycol and water be thermogenetic? Polyethylene glycol is miscible in water, strong acids and alkalis become hot and dangerous when exposed to water, and polyethylene glycol will not. Hope.

Question 6: Is polyethylene glycol a water-soluble polymer compound When polymer is a polymer compound, polyethylene glycol is an alcoholic substance, soluble in water, so polyethylene glycol is a water-soluble polymer compound.

Question 7: Does polyethylene glycol still have the function of endothermy after being dissolved in water No, no.

The polymer is insoluble in water.

Question 8: Does polyethylene glycol contain alcohol Polyethylene glycol is a colorless, odorless, viscous liquid to waxy solid. Soluble in water, ethanol and many other organic solvents.

The vapor pressure is low. Stable to heat. Does not work with many chemicals, does not hydrolyze, does not deteriorate.

Non-toxic, not noticeable to the eyes and**

It smells of alcohol, and most of it is mixed with alcohol.

Question 9: Which is better water solubility between polyether polyol and polyethylene glycol This depends on the molecular weight and the head of the polyether polyol. The molecular weight is too large, and many are insoluble in water. The small molecular weight generally has good water solubility. Polyethylene glycol also depends on the molecular weight.

Summary. Dear, glad to answer for you! Ethanol can be thickened with carboresin alcohol, sodium carboxymethylcellulose, polyvinylpyrrolidone, filler:

For example, silica gel, nano silica, etc. can be dispersed and adsorbed in ethanol, thereby improving its viscosity and rheology. Wait.

What is methanol thickened with?

I use it as a marker.

Dear, glad to answer for you! Ethanol can be closed to thicken the challin with carboresin, sodium carboxymethylcellulose, polyvinylpyrrolidone, fillers: such as silica gel, nano dioxysilicon, etc., can be dispersed and adsorbed in ethanol, thereby improving its viscosity and rheology.

Wait. Kiss, do you want to use markers?

Uh-huh. Kiss, hydroxypropyl methylcellulose can be used.

Pro, hydroxypropyl methylcellulose can adjust its viscosity and thickening effect by changing its molecular weight and the degree of hydroxypropyl methyl filial piety. It has good solubility and stability, and can be well dispersed in liquids during preparation. In addition, Gasf can be used to improve the coating properties and water resistance of markers.

Now pens made with methanol will blend off the paper.

How can I find you if I have any questions about this in the future?

Kiss and pay attention to the teacher, and then you can find the teacher directly.

The phenomenon of smudging on paper is because methanol has good solubility, it can dissolve many inks and dyes, causing them to diffuse to the surrounding paper.

Kiss can also use a desiccant: Put some desiccant in a bag, folder or drawer to absorb methanol and prevent smudging.

It's just drawn and it will blur Will it work with the hydroxypropyl methylcellulose you said?

If it is not serious, you can add some anti-smudging agents, such as some water-soluble polymers, such as polyvinyl alcohol, sodium polyacrylate, etc., these polymers can form a protective film on the paper to prevent the imitation pen and ink from penetrating into the paper. In addition, adding some ink dispersants can also play a similar role in Volchai, such as an appropriate amount of PEG-400 and so on.

There are various varieties of thickeners, mainly inorganic thickeners (mainly swelling) and organic enhancers (cellulose, alkali swelling local source acrylic emulsion, associative polyurethane cool, etc.). Among them, the largest amount is light ethyl cellulose, associative polyurethane cool, and alkali swelling acrylic emulsion.

1.Cellulose.

Cellulose thickeners (HECs) and hydrophobic modified cellulose additives (HMHECs) are the most widely used types of additives in coatings. Cellulose and other polysaccharide enhancers often exist in powder form, and are often ground together with pigments to form pigment slurries. When added later, cellulose and other inorganic powdered thickeners can cause more problems for coatings.

HEC and HMHEC products are available in liquid form to facilitate the production of coatings.

2.Associative polyurethane vinegar.

The thickeners commonly used in water-based coatings are nonionic associative polymers, the most common being hydrophobic modified ethoxylated polyurethane and similar vinyl oxide propylene containing vein, vein-ammonia and ether bonds. Nonionic associative thickeners are usually available in the form of aqueous co-solvent solutions or aqueous solutions. Therefore, when it is used in coatings, it is difficult to disperse, and it takes a long time for the tape to be fully effective.

3.Alkali swelling acrylic emulsion.

Alkali swelling acrylic emulsion The thickener used for water-based coatings is alkali soluble or swollen emulsion, and there are 2 basic types: the traditional endocenoic acid cool (ASE) and the hydrophobic modified associative polyacrylic acid cool (HASE). This type of enhancer needs to be adjusted by adding appropriate alkali to make it change from a low-viscosity emulsion to a water-based thickener.

Hello dear! <>

Glad to answer for you: Polyethylene glycol (PEG) itself is a relatively low viscosity polymer, and if you want to increase its viscosity, you may want to consider adding the following material: Isopropylphenol epoxy resin (EP).

The mixture of PEG and EP forms a gelatinous or semi-gelatinous substance with a high viscosity and viscosity. Polyacrylamide (PAM) is mixed :p EG and PAM to form a clear, viscous gel-like substance that is commonly used in biotechnology and medicine.

The mixture of cetyltrimethylammonium bromide (Ctab), :p EG and CTAB can form a viscous liquid at a certain concentration for the preparation of nanomaterials. It is important to note that the type and proportion of additives will affect the final viscosity and consistency, and experiments are required to determine the optimal formulation.

At the same time, the viscosity of different brands and molecular weights of PEG is also different, please confirm the physical and chemical properties of the selected PEG before use.

Summary. Polyethylene glycol and white oil are both commonly used cosmeceutical ingredients that can be mixed together to form a stable emulsion. To facilitate dissolution and mixing between the two, some emulsifiers can be added.

Polyethylene glycol and white oil are both commonly used cosmeceutical ingredients that can be mixed together to form a stable emulsion. For the wheel ridge to promote dissolution between the two and pie or mix, you can add some milky tung wuhua agent.

What emulsifier is added to ethylene glycol and white oil.

Can you buy it?

Specifically, emulsifiers such as anionic, cationic, or nonionic surfactants, such as Tween 80, Span 20, Span 80, Cremophor RH40, and many more, can be used. These emulsifiers help to mix polyethylene glycol and white oil evenly, and to balance the spine and prolong the stability of the emulsion.

Polyethylene glycol and white oil are both chemical raw materials, and there are also sellers on this idea. However, it should be noted that these chemical raw materials require special storage and use conditions, and it is necessary to understand the quality and use of the product before purchasing, so as not to bring safety hazards or health problems to yourself or others.

Emulsifiers are available in **.

For example, some large chemical companies, pharmaceutical manufacturers or online pharmacies provide emulsifier sales services.

Is that the case? When choosing an emulsifier, consider big brands of emulsifiers, such as Sigma-Aldrich, Merck, Thermo Fisher Scientific, etc., which are usually of reliable quality and easier to obtain technical support and after-sales service.

You're a bit cheap, not very reliable.

When choosing an emulsifier, look at the purity of the emulsifier product. In general, high-purity emulsifiers are more stable in quality and have better results.

The emulsifier is also a factor to consider when purchasing. The quality of low emulsifiers is not the same, and high emulsifiers are not necessarily the best choice. It is recommended to purchase emulsifier products according to their own use needs and economic strength.
