Valve sacks also known as valve bags are designed for high speed filling on spout packers and are usually used to hold granular products from fine powders such as cement, through to plastic polymers, crumb rubber and granular foodstuffs such as sugar. Valve sacks are available made from paper, extruded plastic (LDPE), raffia or woven polypropylene etc. This report focus on the valve bags from 20 to 100 pounds.Valve bag market concentration is low, and a large number of low-priced products will r ...

Biodiesel is an alternative fuel for diesel engines that is produced by chemically reacting a vegetable oil or animal fat with an alcohol such as methanol or ethanol.Biodiesel catalyst includes hydroxide, sodium methylate solution and other. Hydroxide catalysts are usually NaOH and KOH. Currently, Dow produces hydroxide series catalysts. Sodium methylate solution is more and more popular during past few years. Also, it is the most common used biodiesel catalyst. In 2016, sodium methylate solutio ...

The high production speeds in textile weaving and knitting impose high demands on the yarns. The yarns need to be rapidly unrolled from the cones and must not break during weaving or knitting. In order to achieve these requirements, yarn lubricants must improve the gliding properties of the yarn. Other aspects such as antistatic or softness are also important for smooth processes. In order to avoid breakage, the yarn should show a preferably low and homogeneous friction value. This is essential ...

Dispersant or Dispersing Agent is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping. The role of the dispersant is to make the dispersion process easier and more stable. Dispersants consist normally of one or more surfactants, but may also be gases.Dispersants is mainly classified into two types: anionic type and cationic type. And anionic type is the most widely u ...

Soy protein isolate is the soy protein with the highest content of protein. It is made from defatted soy meal by removing most of the fats and carbohydrates, yielding a product with 90 percent protein. Therefore, soy protein isolate has a very neutral flavor compared to other soy products. Because most of the carbohydrates are removed, the intake of soy protein isolate does not cause flatulence. Pure soy protein isolate is difficult to find in stores and is mainly used by the food industry and l ...

Wood tar is produced from a variety of natural materials through destructive distillation. Wood tar can be extracted from straw, wood, etc. Wood tar is type of tar with a mixture of free carbons and hydrocarbons.Wood tar is mainly classified into four types: resinous tars, hardwood tars, other tars. Resinous tars mainly include pine tar, and hardwood tars include beech tar, oak tar, etc. other tars are mainly made from straw, nuts, etc. And resinous tars are the most widely used type which takes ...

3-hydroxypyridine is pyridine derivative with hydroxyl in position 3. It is light brown powder and is widely used in pesticide, pharmaceutical and dyes and so on. And 3-hydroxypyridine is irritating to eyes, skin and respiratory system.3-hydroxypyridine industry has low technology barrier and is labor intensive industry. Currently, there are several producing companies in the world 3-hydroxypyridine industry. The main market players are Koeichem, Huahong, Chengjie, Chunfeng, Lianrun and Yanuo. T ...

Lead is a chemical element with symbol Pb and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and has a relatively low melting point.Lead is a soft and malleable metal belonging to the carbon group. It is the heaviest non-radioactive element which occurs naturally on earth in the form of four isotopes: lead-208, 207, 206, and 204. It is generally found in ores with copper, silver and zinc and is extracted together with these metals. Le ...

The Lithium ion battery separator shutdowns the mechanism of the battery when abnormal heat generation occur with the battery cell. Lithium ion battery separators are also used to prevent physical contact between anode and cathode while facilitating ion transport thereby preventing short circuit and increasing reliability of the lithium ion battery.Lithium ion battery separator are primarily manufactured from non-woven fiber, polymer films and ceramic material, where porous membrane are commonly ...

Liquid crystal on silicon (LCoS or LCOS) is a miniaturized reflective active-matrix liquid-crystal display or "microdisplay" using a liquid crystal layer on top of a silicon backplane. It is also referred to as a spatial light modulator.Liquid Crystal on Silicon (LCoS) is a newest display technology with a rapidly growing market. LCoS is used in several industries like entertainment, medical, defense, automation etc. Other display technologies like LCD and DLP are major competitors for LCoS tech ...
