Why MHEC is being preferred over HPMC for Cellulose Ether

图片
Cellulose Ether is derived from Cellulose and is a water-soluble compound used in several industries. It finds its usage mainly in the construction, food, pharmaceutical, and cosmetics industries. Specifically, Cellulose Ether is primarily used in the construction sector as it acts as a binder, thickener, and water retention agent in construction. There are different grades of Cellulose Ether, which have their applicability and properties. The two primary grades of  Cellulose Ether HPMC   (Hydroxypropyl Methyl Cellulose) and MHEC (Methyl Hydroxyethyl Cellulose) have varied similarities, yet one is more preferred than the other in recent days. Nowadays, MHEC grade of Cellulose Ether is more preferred than the HPMC grade in the construction industry. Though, both are being utilized widely for increasing bond strength and water retention capacity of a dry mixture of cement and gypsum, few properties differentiate them. The first property differentiating Methyl Hydroxyethyl Cellul...

Top 10 Factors Affecting the Quality of Injection Molds

图片
    Mold manufacturing  is a complex process, from design, processing, assembly, commissioning, and other steps, to the final real use, in the whole life cycle, there are 10 main factors that affect the quality of the mold as follows.   1. Mold steel Steel is the decisive factor of mold quality, and choosing reasonable steel is the most important. The criteria for choosing steel are   ①The requirements of injection materials different plastics to use different steel, such as the requirements of high polish, corrosion resistance, etc..   ②Price steel properties can be good, not the more expensive the better; taking into account the cost factors of the mold, mold steel should be used and mold life corresponding to the material, to avoid unnecessary waste; general P20 material life of about 300,000; 2738 material in 500,000 no problem, H13/2344 usually in 800,000-1,000,000 or more, can be selected according to the situation.   ③Surface treatment The surfa...

Difference between COB Lights and SMD Lights

图片
  LED lights  are constantly being improved for better use, greater versatility and more efficient use of electricity. Compared to traditional incandescent lights, different models of LED lights  are very popular, mainly because they can use less energy and last about 25 times longer.   This article will focus on difference between COB light and SMD light.   SMD vs. COB: What is an SMD? SMD or "surface mount device" LEDs are the most common LEDs on the market.  LED chips  are permanently fused to a printed circuit board and are popular because of their versatility. You can find it in light bulbs and light strings, and even in notification lights on cell phones.   SMD LED chips come in a variety of sizes. SMD LEDs can accommodate chips with complex designs, such as the 5mm wide SMD 5050. on the other hand, the SMD 3528 is 3.5 mm wide. SMD chips are small, almost approaching the design of a flat square computer chip. High Power 160W Blue & White...

Things You Should Know About Stay Wire

图片
  During wiring installations, strands of galvanized steel wires are used. These wires are capable of sustaining the mechanical load. A stay wire manufacturer mostly deals in projects which are connected to the electricity industry. These are used to  ‘ stay ’  the power poles and tower structures and hence it got its name. These are also commonly referred to as the  “ guy wire ” .   Basically, if any heavy equipment is needed to be kept steady in structures like cell towers or utility equipment or in heavy construction sites then stay wires are put to use. In these situations, due to continuous load, over a long period of time, the poles might bend or the line might get twisted. So, the stay wire for an electric pole is used to provide horizontal support to the prolonged load. Preformed Armor Rods Equipment Preformed armor rods equipment  is a kind of preformed armor rods forming machine, suitable for processing performed strain clamps, preformed suspensio...

Is Tricalcium Phosphate Bad for Your Health?

图片
    Tricalcium phosphate  is a supplement form of calcium phosphate and is used to treat or prevent calcium deficiency. Calcium is primarily important for healthy bones and teeth. Calcium is naturally found in foods like dairy, nuts and seeds, and dark, leafy vegetables. In addition to its use as a supplement, tricalcium phosphate is used as an anti-caking agent in powdered food items. It is also used as an additive in some processed foods to boost calcium content.   Is it safe? Tricalcium phosphate is a calcium salt found in many nutritional supplements. It is considered safe to use as a food additive and supplement, but there are some people in whom it has contraindications, and there can be interactions and side effects. Many people wonder about the safety of tricalcium phosphate, including side effects and whether it causes cancer. Some people take supplements containing tricalcium phosphate to supplement their daily calcium intake if they are not getting enough ...

5 Tings You Need to Know About HDPE Double Wall Belows
