In recent years, the demand for pharmaceutical intermediates has increased significantly due to global health challenges such as the COVID-19 pandemic. This surge has prompted manufacturers to enhance their production capabilities and innovate their processes. Modern manufacturing techniques, including continuous flow chemistry and green chemistry, have gained traction as they offer more efficient and sustainable methods for producing intermediates. By reducing waste and energy consumption, these processes contribute to a more environmentally friendly pharmaceutical industry.

- Knitting is also divided into two types, one is the ordinary knitting type, the other is the knitting type of embossing. Embossing is not simply used for knitting, but patterns can also be woven to add beauty. In short, it is a variety of steel wire as raw materials, through the professional screen material technology processing. It is widely used, mainly in construction.

5, the concentration of plating aid can not be too high, which is a factor that can not be ignored to reduce zinc consumption. The concentration of plating aid should not be too high. The galvanized line must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution should be controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is arbitrarily added without the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.

- Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.

When buying large galvanized wire, first look at the hardness of galvanized wire, only after the hardness reaches the standard can be used. The hardness standard of large coil galvanized wire is a very important performance index and an economical test method. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad.

Usually according to the general people, the blade barbed rope is the guardrail, widely used in garden apartments, military bases, private residential areas, government machinery where there is a fence, generally used blade barbed rope. The biggest advantage of the blade is that the protective effect is good, and the installation and maintenance is very convenient, strong isolation ability, good resistance effect, etc.

PVC coated barbed rope is widely used for railway highway protection, but also for safety protection of rivers, embankments and seawalls, so as to better protect the safety of people and animals.
- Hot dip galvanized wire 5#-28#, including 500-1000 kg large plate of hot dip galvanized wire. Our hot dip galvanized wire is made of national standard low carbon steel wire after drawing molding, pickling rust removal, high temperature annealing and other processes. The products have the characteristics of strong flexibility, good plasticity and so on. The zinc content can reach 360 g /m2, which is welcomed by customers. We can also provide various specifications of galvanized wire according to customer requirements. The PRODUCTS ARE WIDELY USED IN construction, HIGHWAY fence, TIE-flower, weaving and other industries, mainly used in the manufacture of wire mesh, nail making, highway barrier and construction engineering binding wire, etc.

6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.

The wire diameter of raw materials used in different types of barbed rope is also very different, but in the production and processing process of barbed rope need to know the amount of use.
- First of all, we need to understand that the electrical conductivity of the wire depends on its material and size, and is not affected by the surface treatment method. Whether galvanized treatment or wire drawing treatment, they are the surface of the steel wire treatment, will not change the basic physical properties of the steel wire, electrical conductivity will not be affected. Therefore, in theory, the galvanized wire drawing treatment should not have any effect on the electrical conductivity of the steel wire.

Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
- Galvanized wire hexagonal mesh material: cold galvanized wire, hot galvanized wire, to draw wire
- 2. When the weather is too dry and humid, remember to blow dry the cage or move it to a place with heating to prevent dry crack damage.
