Rolling Paper
Rolling paper is a specialty paper used for making cigarettes (commercially manufactured filter cigarettes and individually made roll-your-own cigarettes). Rolling papers are packs of several cigarette-size sheets, often folded inside a cardboard wrapper. They are also known as 'blanks', which are used to encase tobacco or cannabis. It may be flavoured. Rolling papers are also used for rolling cannabis cigarettes called Joints. History The first cigarette paper was produced in Alcoy, Spain, in 1764. Paper cigarettes became popular in the second half of the 19th century, displacing the more expensive cigars and cigarillos. As cigars and cigarillos were expensive, the beggars of Spain would collect the cigar butts from the ground and roll them in pieces of paper to be smoked. During the Crimean War this culture became more prevalent and British soldiers learned how to roll tobacco in newspapers. Frequent use of rolling paper became a custom, and to fulfil the need, rolling paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, Textile, rags, poaceae, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and Housekeeping, cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 Common Era, CE, by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemp
Hemp, or industrial hemp, is a botanical class of '' Cannabis sativa'' cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. Although chemotype I cannabis and hemp (types II, III, IV, V) are both ''Cannabis sativa'' and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Safe Cigarettes
Fire safe cigarettes, abbreviated "FSC", also known as lower ignition propensity (LIP), reduced fire risk (RFR), self-extinguishing, fire-safe or reduced ignition propensity (RIP) cigarettes, are cigarettes that are designed to extinguish more quickly than standard cigarettes if ignored, with the intention of preventing accidental fires. In the United States, "FSC" above the barcode signifies that the cigarettes sold are fire standards compliant (FSC). Fire safe cigarettes are produced by adding two to three thin bands of less-porous cigarette paper along the length of the cigarette, creating a series of harder-to-burn “speed bumps”. As the cigarette burns down, it will tend to be extinguished at each of these points unless the user is periodically intensifying the flame by inhaling. Contrary to myth, FSC cigarettes use no more ethylene vinyl acetate (EVA) adhesive than conventional cigarettes, and its use as an adhesive predates the introduction of FSC technology."Myths versus r ...

Poly(vinyl Alcohol)
Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula H2CH(OH)sub>''n''. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water. Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure, biocompatible hydrogels which have been used for a variety of applications such as vascular stents, cartilages, contact lenses, etc. Uses PVA is used in a variety of medical applications because of its biocompatibility, low tendency for protein adhesion, and low toxicity. Specific uses include cartilage replacements, contact lenses, and eye drops. Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest applicatio ...

Potassium Citrate
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K3C6H5O7. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly hygroscopic and deliquescent. As a food additive, potassium citrate is used to regulate acidity, and is known as E number E332. Medicinally, it may be used to control kidney stones derived from uric acid or cystine. In 2020, it was the 297th most commonly prescribed medication in the United States, with more than 1million prescriptions. Synthesis Potassium citrate can be synthesized by the neutralization of citric acid which is achieved by the addition of potassium bicarbonate, potassium carbonate or potassium hydroxide to it. The solution can then be filtered and the solvent can be evaporated till granulation. Uses Potassium citrate is rapidly absorbed when given by mouth, and is excreted in the ...

Sodium Citrate
Sodium citrate may refer to any of the sodium salts of citric acid (though most commonly the third): * Monosodium citrate * Disodium citrate * Trisodium citrate The three forms of salt are collectively known by the E number E331. Applications Food Sodium citrates are used as acidity regulators in food and drinks, and also as emulsifiers for oils. They enable cheeses to melt without becoming greasy. It reduces the acidity of food as well. Blood clotting inhibitor Sodium citrate is used to prevent donated blood from clotting in storage. It is also used in a laboratory, before an operation, to determine whether a person's blood is too thick and might cause a blood clot, or if the blood is too thin to safely operate. Sodium citrate is used in medical contexts as an alkalinizing agent in place of sodium bicarbonate, to neutralize excess acid in the blood and urine. Metabolic acidosis It has applications for the treatment of metabolic acidosis and chronic kidney disease. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seignette's Salt
Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of tartaric acid first prepared (in about 1675) by an apothecary, Pierre Seignette, of La Rochelle, France. Potassium sodium tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity. This property led to its extensive use in "crystal" gramophone (phono) pick-ups, microphones and earpieces during the post-World War II consumer electronics boom of the mid-20th century. Such transducers had an exceptionally high output with typical pick-up cartridge outputs as much as 2 volts or more. Rochelle salt is deliquescent so any transducers based on the material deteriorated if stored in damp conditions. It has been used medicinally as a laxative. It has also been used in the process of silvering mirrors. It is an ingredient of Fehling's solution (reagent for reducing sugars). It is used in electroplating, in electronics and piezoelectricity, and as a combusti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnesium Carbonate
Magnesium carbonate, (archaic name magnesia alba), is an inorganic salt that is a colourless or white solid. Several hydrated and basic forms of magnesium carbonate also exist as minerals. Forms The most common magnesium carbonate forms are the anhydrous salt called magnesite (), and the di, tri, and pentahydrates known as barringtonite (), nesquehonite (), and lansfordite (), respectively. Some basic forms such as artinite (), hydromagnesite (), and dypingite () also occur as minerals. All of those minerals are colouress or white. Magnesite consists of colourless or white trigonal crystals. The anhydrous salt is practically insoluble in water, acetone, and ammonia. All forms of magnesium carbonate react with acids. Magnesite crystallizes in the calcite structure wherein is surrounded by six oxygen atoms. The dihydrate has a triclinic structure, while the trihydrate has a monoclinic structure. References to "light" and "heavy" magnesium carbonates actually refer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
