Basically, the chemical products with the word Cuprous are harmful to the human body. Everyone must pay attention to it in life. Cuprous Chloride is a heavy metal salt, which is toxic, and the adult lethal dose is 0.9g/kg.

Why Cuprous Chloride is toxic? This is based on its chemical composition. Everyone knows that 8-hydroxyquinoline Copper is a heavy salt, rich in copper ions, which can cause the deterioration of human protein components, thereby poisoning people’s health. Low concentrations of 8- If the hydroxyquinoline Copper solution is accidentally touched, it can be rinsed with water immediately. If the concentration is high, it will be sent to the hospital urgently.

   When the paper is saturated with water, the strength of the paper drops rapidly due to water molecules breaking and replacing the hydrogen bonds existing between the fibers, reducing to 3%~10% of the original dry strength of the paper. The retention strength of wet paper can generally retain 10-30% or even higher dry tensile strength. It depends on various process factors in the process of adding wet strength agent. The following are the common factors that influence the wet strength of Electroplating Grade Copper Sulfate Pentahydrate during use.

1. The influence of fiber raw materials on the effect of wet strength agent

The wet strength effect of PAE on wood pulp is higher than that of straw pulp and recycled pulp. The higher the effective negative charge of the pulp, the more wet strength agent can be absorbed, so the wet strength effect is better.

    Pay attention to Cupric Oxide Powder operation: airtight operation, local exhaust. Operators strictly abide by the operating procedures and must receive special training. It is recommended that operators wear chemical safety glasses, self-priming filter dust masks, rubber gloves and anti-toxic penetration work clothes to avoid contact with reducing agents and alkali metals to avoid dust generation. To prevent damage to the packaging during transportation, load and unload with care. Equipped with leakage emergency treatment equipment, empty containers may be hazardous residues.

   Warning for storing Cupric Oxide Powder: Please store in a cool and ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from reducing agents, alkali metals and edible chemicals, and avoid mixed storage. The storage area should be equipped with suitable materials to prevent leakage.

Electroplating Grade Copper Sulfate Pentahydrate is more common in life. It is a kind of food additive. We often buy foods and often see preservatives or preservatives. These contain this Electroplating Grade Copper Sulfate Pentahydrate, but we It is rarely taken apart. Electroplating Grade Copper Sulfate Pentahydrate has many functions. It can be used as a preservative and bleaching agent in daily life. When used as a preservative, it can maintain the freshness of food. When used as a bleaching agent, it can bleach items. So appropriate use of these is not harmful to our human body, but there is a certain amount of consumption, the following analysis:

 Is Electroplating Grade Copper Sulfate Pentahydrate harmful?

Cupric Oxide Powder (also known as PAC, polyaluminum, polyaluminum chloride) (Al) product (Product) is mainly used as a coagulant or flocculant in industrial wastewater treatment (chǔ lǐ), because its molecular chain contains a certain amount of extreme Sex genes can absorb the suspended solid particles in water, and make the particles form large flocs. Cupric Oxide Powder Iron Cupric Oxide Powder is an inorganic polymer coagulant. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, it is an inorganic polymer water treatment agent with larger molecular weight and higher charge. The characteristics of) are mainly determined by the working principle of the pressure atomizer. When the solid Cupric Oxide Powder is diluted into a liquid, firstly, according to the raw water, do a small test before use to find the best dose. There are many synthesis methods of Cupric Oxide Powder iron Cupric Oxide Powder. According to the different raw materials, it can be

    The molecular formula of Cupric Oxide Powder is the same as that of Oxide Powder, but Oxide Powder is a composite polymer. The molecular structure becomes larger and the adsorption ability is strong. The water purification effect is better than all traditional inorganic water purifiers. The flocculation formed by the raw water is large, the precipitation speed is fast, the activity is high, and the filterability is good. And it has strong compliance with various raw waters, and has minimal impact on the PH value of water (PH value 4-11).

    Regardless of the turbidity of the raw water, the concentration of wastewater pollutants, the purification effect is significant. Low dosage: less corrosive to equipment and pipelines, easy to operate, small dosage, and low purification cost. The application of polymerized Oxide Powder is very common,

  Copper powder is a thing formed by grinding copper into powder. There are many varieties, such as: atomized copper powder, electrolytic copper, Cupric Oxide Powder, 663 bronze powder. And because the copper powder is in powder form, the overall area in contact with the air will be wider. If it is stored in an unsealed way, it will be very susceptible to oxidation.

   and other copper powder uses: widely used in powder metallurgy products, friction materials, conductive inks, electrical carbon products, chemical contacts, diamond products, electrical alloys and other industries. The quasi-spherical and spherical copper powder has a high bulk density. It is widely used in injection molding, welding materials, electronic materials and other industries.

   Atomized copper powder: It is light rose red irregular powder, produced by atomization method. Widely used in diamond tools, powder metallurgy parts, chemical catalysts, carbon brushes, friction materials

     Cupric Oxide Powder is iron-grey. In diamond tools, the use of iron-based separating agents has been rapidly developed in recent years, mainly because iron-based separating agents not only meet the requirements, but also have economic efficiency that other separating agents cannot compare. Cupric Oxide Powder has a dual role in the formulation. One is to form cementite carbide with diamond the other is to alloy with other elements to strengthen the matrix.


    The adhesion work between iron and diamond is higher than that of drilling. After a reasonable choice of matrix formula of iron-based separator diamond tools, coupled with appropriate sintering process, the matrix performance can reach the performance index of cobalt-based matrix, and it can also maintain a better diamond A small loss of strength improves the control of diamond. The moisture content

Cupric Oxide Powder drying is the process of removing moisture from various materials. Various materials can be solid, liquid or gas. The solid can be divided into bulk materials, fiber materials, granular materials, fine powder materials, etc. Generally it is the moisture in the material, but it can also be other solvents. Moisture is the object here.

There are three types of drying methods:

(1) Mechanical dehydration method

The mechanical dehydration method is to squeeze out part of the water by pressing the material. Commonly used methods include pressing, sedimentation, filtration, and centrifugal separation. The mechanical dehydration method can only remove part of the free moisture in the material, and the combined moisture remains in the material. Therefore, the moisture content of the material after the mechanical

    For Cupric Oxide Powder wet superfine pulverization or other wet powder milling processes, the superfine powder will form hard agglomerates during drying. Therefore, surface modification after the wet superfine pulverization and before drying can not only Prevent the ultrafine powder from forming hard agglomerates that are difficult to depolymerize during drying, and because the particles are easily dispersed in the wet state, the contact opportunities between the surface modifier molecules and the particles are more uniform, and the surface modification effect is better.
   The key technology of wet surface modification is the use method, formula and drying process equipment of surface modifier. The reason is that most organic surface modifiers are insoluble in water and cannot be added directly in addition, the drying temperature should be controlled appropriately and not too high to avoid decomposition of the surface modifier. The characteristics of this technology
