5% - 2% of the base is as follows:
The mixing of the two is to obtain a product with special properties. The green one is more viscous and waterproof. It is viscous to the ground, and it is semi-solid under normal conditions. In case of high temperature, it can flow. And because of its water repellency, it can effectively isolate water, so it is used in waterproof projects.
And the substrate is stable and has certain properties. The characteristics of the seed make it can be mixed and reversed, and in some cases it can play the effect of curing and fixing other materials.
5% green and 2% green, the viscosity of green may be modified by the addition of green groups. The green group may be used as a filling or modification, and the green interaction. On the one hand, the particles of the green group are dispersed in the green group, or the quality of the green group is increased, so that the mixed material can improve the mechanical properties, such as the anti-forming ability. On the other hand, the two may be biochemically reversed, and the original chemical properties of the green group can be changed, which affects its resistance and aging properties.
The biochemical reaction angle of the green group or some acidic or active ingredients in the green group can be used to form new compounds, which may improve the integrity of the mixture. In addition, during the mixing process, or due to the interaction force of the two molecules, the molecular arrangement is changed, which affects its physical properties, such as melting, viscosity, etc. In addition, the mixture of 5% to 2% base is affected by the respective characteristics and interactions of the two, and exhibits special properties, which may be used in many fields such as engineering and construction.

The common synthesis methods of 5-hydroxy- 2-furanyl are mostly based on ancient methods, and each has its own ingenuity.
First, furfural is used as the starting point and can be obtained by oxidation. Furfural is a raw material derived from biomass. Under specific reaction conditions, it is oxidized with suitable oxidants, such as potassium permanganate, potassium dichromate, etc., to obtain 5-hydroxy- 2-furanyl. This process requires careful control of the reaction temperature, pH and the amount of oxidant. If the temperature is too high, it is easy to cause excessive oxidation and damage its products; acid-base imbalance also affects the rate and yield of the reaction.
Second, by means of organic synthesis skills, furan is used as a base to introduce hydroxyl groups. Halogenated furans are often used as intermediates to react with halogenating agents first to obtain halogenated furans, and then nucleophilic substitution is performed to replace halogens with hydroxyl groups. Among them, the selection of halogenating agents and the activity of nucleophiles are all key. If the activity of halogenating agents is too strong, it is easy to cause polyhalogenated products; if the activity of nucleophiles is insufficient, the reaction is difficult to advance.
Third, the route of biosynthesis is also possible. Some microorganisms, with specific enzyme systems, can catalyze related substrates to generate 5-hydroxy- 2-furan groups. This method is green and environmentally friendly, but it requires strict conditions for the culture of microorganisms. Temperature, nutrients, ventilation conditions, etc., are all related to the growth of microorganisms and the activity of enzymes. If you are not careful, it will affect the generation of products.
Or extracted from natural products, the metabolites of some plants or microorganisms may contain 5-hydroxy- 2-furan groups. After extraction, separation, purification and other steps, pure products can be obtained. However, the content of natural products is often low, and the extraction process is complicated. High-efficiency separation methods, such as column chromatography, high-performance liquid chromatography, etc., are required to obtain satisfactory purity and yield.

5% mercury-2% thallium base is volatile to its physical properties. It can be slowly volatilized at room temperature to form mercury vapor. Mercury vapor is toxic. Inhalation can cause human poisoning, damage the nervous system, kidneys, etc.; mercury has high density and good fluidity in liquid state. Mercury can dissolve a variety of metals to form amalgam, which has special physical and chemical properties. Thallium is soft in nature and has a low melting point. Thallium and its compounds are highly toxic. It will accumulate when it enters the human body, damaging the nervous system, digestive system, hair, etc. Thallium is easily oxidized in the air, and the solubility of its compounds varies.
Mercury and thallium are mixed, and the reaction rate and product are changed in terms of chemical properties or due to interaction. In terms of physical properties, physical parameters such as material density and melting point after mixing or deviate from the value of the two alone to form new physical properties. The mixture is toxic or synergistically enhanced, which is more harmful to organisms and the environment. And because of its physical and chemical properties, the migration and transformation laws in the environment are complex, or it is transmitted through water, soil, and air, causing wider pollution.

The price of hardware and grain rice in the world today is related to people's livelihood, and everyone has observed it. Among the hardware, copper, iron, tin and lead are widely used, either as utensils or for building houses, which are indispensable for the people's livelihood and the state's maintenance. The grain is the food of the people. If it is not available for a day, it will be discouraged.
The price of hardware often varies due to the distance of the origin, the difficulty of mining, the time of abundance, and the supply and demand of the city. If the origin is close and easy to mine, the supply is sufficient but the demand is small, the price will be lower; if the origin is far away, the mining is difficult, and the time is eventful, the fortifications are frequent, and there are many people in need but few suppliers, the price will be high.
The price of grain is related to the year. When the year is full, the warehouses are solid, and merchants compete for sales, and the price is self-leveling; when the year is sorry, the harvest is thin, and the people compete for purchases, and the price is high. And the convenience of transportation and the lack of warehousing are also related to the price. In a well-connected place, grain transportation is easy to reach, and the price is relatively stable; in a remote place, transportation is difficult, and the price may be high. If the warehousing is full, the market price can be stabilized; if the warehousing is empty, the price will rise.
In addition, the implementation of government decrees is also an important factor affecting prices. If the government adopts a light tax policy to reduce the burden on merchants, the logistics of goods will be smooth, and the price is expected to be stable; if the tax is heavy, the cost of merchants will increase, and it will be transferred to the price, And the government sets up warehouses that are always flat, and the years are abundant to buy them, and the years are sorry to sell them, so that the price of grain can also be balanced.
The market price of hardware and grain is affected by various factors. Officials should be aware of the situation and make good use of government decrees to make prices flat, the people will be safe, and the country will prosper; businesspeople should judge the situation and move according to the times to make profits; those who work for the people should also work hard to prepare for emergencies, adapt to changes in market prices, and seek a stable livelihood.
