Hydroxypropyl Starch Ether   is unfamiliar to many people, and thought to be a little different from common starch, but that’s not the case. HPS has a very small amount used in mortar products, and a very low addition amount enables to achieve very good quality effects. Hydroxypropyl Starch Ether is a  white fine powder  free from plasticizers, prepared from natural plants, which are modified, highly etherified, and spray dried. It is totally different from common or modified starch.   Hydroxypropyl methyl cellulose ​ (HPMC for short), also known as hypromellose or hydroxypropyl methyl cellulose ether, is prepared from selection of highly pure cotton cellulose, treated in 35-40℃ alkali liquor for 0.5h, squeezed to smash cellulose, and properly aged at 35℃ to make average polymerization degree of alkali fiberobtained within the required range. Put alkali fiber into the reaction kettle, then add propylene oxide and methyl chloride in order for 5h etherificati...

  With the continuous progress of society, in the busy urban life of modern people, more and more people hope for convenience and speed. Stretch film has realized this desire in the packaging industry, making product packaging easier. Stretch film is the most popular packaging material in the modern era, and can be used in many industries, such as food, beverages, candy, stationery, etc.; and stretch film can meet the requirements of moisture-proof, dust-proof and touch-proof products. It has functions such as stealth replacement and transparent display, so it can also replace all kinds of cartons; so what materials are they made of? The MPE used to make the  stretched film   is a high stereoregular polymer, and the stretched film is a high stereoregular polymer with a narrow molecular weight distribution, which can accurately control the physical properties of the polymer, so the performance is further improved; due to the narrow molecular weight distribution of MPE , Th...

  Due to the use of  stainless steel wire mesh   as the material of the metal mesh, it has the advantages of high strength and good softness. Stainless steel wire mesh is not easy to be cut by hard objects as a construction fence, can adapt to the harsh outdoor working environment, can be reused, and can be used multiple times after one input, reducing costs. Stainless steel wire mesh is used for flood control, traffic, construction or water conservancy safety frame fence, basic mesh or external mesh. Due to the use of stainless steel as the material of the metal mesh, it has the characteristics of corrosion resistance, high strength and good softness. Stainless steel wire mesh is not easy to be cut by hard objects as a construction fence, and can adapt to the harsh outdoor working environment. When the stainless steel wire mesh is used for water conservancy, it can effectively prevent the bank from collapsing due to the scour of the current. Stainless steel wire mesh is ...

    Different terms used for  arresters  are sometimes confusing even professional engineers and electricians use them interchangeably. Now let’s discuss all these arresters in details.   Table of Contents   What is a Surge Arrester? What is a Lightning Arrester? Main Differences between Surge Arrester and Lightning Arrester Should You Use Surge Arresters or Lightning Arresters?   Surge Arrester   1. The  surge arrester  will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point. 2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes. 3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) . Lightning arresters   1. The lighting arrester...

Pharma is a big industry. However, the value chain can be broadly divided into two categories: API and finished formulation.  API makes up a part of the drug that enables the latter to produce the desired effect.  China is one of  the leading suppliers of API . When the pandemic severely disrupted the supply chain in China, the pharma industry was affected for the time being due to the shortage of raw materials.     What is API in Pharma? API full form in pharma is Active Pharmaceutical Ingredient. A simple API meaning in pharma is that it's a raw material that is included in medicines. In reality, there's a subtle difference between API and raw materials. But first, talking about what is API in pharma, it is a biologically active component used in drugs (capsules, tablets, injectables, more) to produce the intended outcome. It is one of the two main ingredients in medicine, the other one being excipients, a chemically inactive substance that delivers ...

  Ball bearings are some of the most commonly used bearings in rotary movement applications. They comprise a row or multiple rows of balls between inner and outer raceways. This design capitalizes on the concept that rolling elements produce less friction than sliding elements. One ring is normally attached to the rotating assembly, or shaft, and as it rotates the balls roll around the inner raceway, while the other ring remains stationary. This allows for rotational movement with an extremely low friction coefficient, making it great for applications with high speeds and low friction requirements. Bearings typically need to handle two types of loads: thrust loads and radial loads. Thrust loads, also called axial loads, are forces acting parallel to the bearing axis, while radial loads act perpendicular to the bearing axis.  Ball bearings   can withstand both thrust and radial loads. However, they have a relatively low load capacity, so they are typically used in applicat...

  When using   Bevel Type Partition Board , the compartment must undergo special modification, i.e.to install ventilation slots at two upper corners of the compartment. A number of thermal bulkhead can be used in the compartment based on the needs to divide in into different sections, the temperatures of different sections are managed by the temperature control on the ventilation slots. Product Application: An insulated bulkhead is a thermal barrier in a trailer, truck body or van that separates fresh, frozen or dry goods. This allows multiple temperatures in one vehicle, or the reduction of cooled space to reduce energy consumption   Product Modality: This product is divided into five types according to different user needs, including Basic Type, Bevel Type, Groove Type, Temperature Control Type, and Orbit Type. It can also be customized according to your own use needs. We provide customers with fittings, such as supporting rods, guard bars, goods-controlled belts, and f...
