Pervaporation membranes can be classified into organic and inorganic membranes. NaA zeolite membrane, as an inorganic membrane, has well-defined zeolitic pores with high hydrophilicity. The pore size of NaA zeolite membrane is 0.42 nm, which is larger than water molecule (~ 2.9 A) and less than most of organic molecular diameters. Therefore, the membrane shows excellent permselectivity and flux for separation of water from organics. Compared to organic membranes, the zeolite membranes have several advantages including higher permeation flux, higher separation factor and better thermal/chemical stability. During the separation process, the feed solvent is introduced to the feed side of the membrane, and the H2O is removed from the permeate side. The low pressure of the permeate side is maintained by the use of a vacuum pump. Water molecules are preferentially adsorbed on the surface of the membrane, and then permeate through NaA zeolite membrane layer. The driving force of the process is the difference in the partial pressures of water across the membrane. In the feed side, the dehydrated product can be achieved on the retentateï¼?and the H2O in the permeate side is condensed and drained. Pervaporation process The pervaporation process is not limited to the gas/liquid equilibrium of the solvent. It can achieve high-purity solvent with low energy consumption, and separate solvents which are difficult to be achieved by traditional separation methods such as distillation, extraction and adsorption. It has obvious advantages for separation of azeotropic or close azeotropic mixtures and dehydration of solvents with minor or trace water, which is a promising technology for substitution of traditional separation technologies. It has a promising application in energy, petrochemical industry, biological medicine, electronics, environmental protection and other fields.

The main treatment of chest stagnation, vomiting, Eat less, stomach yin deficiency, mouth thirst, Hyperactivity cough and excessive drinking. With appetizers, thirst quencher lungs effect. Orange nutrition is also very rich, an orange almost every day to meet the human body needs vitamin C content. And the orange contains more than 170 kinds of plant compounds and more than 60 kinds of flavonoids, most of which are natural antioxidants. Organs rich in nutrients are hypolipidemic, anti-atherosclerosis and other effects, the prevention of cardiovascular disease in the great benefit. Juice contains a substance called "Norlylin", with the ability to inhibit and kill cancer cells, the prevention of gastric cancer. Orange peel was orange-red, flesh was granular, and grapefruit is very similar. Orange peel thin meat, juicy sweet and sour, peeled orange orange water can overflow. Citrus fruit nutrient-rich, color and flavor and excellent, both fresh, but also processed into a variety of fruit juice-based processing products. Citrus production is the first of the fruit, citrus juice accounted for 3/4 of the juice, widely favored by consumers. According to the Central Health Research Institute, citrus per 100 grams of edible parts, containing 0.05 mg of riboflavin, 0.3 mg of niacin, 16 mg of ascorbic acid (vitamin C), 0.9 g of protein, 0.1 g of fat, 12 g of sugar, 0.2 grams of fiber, 0.4 grams of inorganic salts, 26 mg of calcium, 15 mg of phosphorus, 0.2 milligrams of iron, and 221.9 joules of calories. Orange carotene (vitamin A original) content after apricot, higher than other fruits.
Chestnut : Chestnut produces higher energy, is a nut type, contains the starch is very high. According to the investigation of dry chestnut carbohydrates reached 77%, fresh chestnuts have 40%, is the potato 2.4 times; chestnut which is 4% to 5% protein content, although not as peanut, walnut, but also than cooked The rice is taller. Fresh chestnuts contain vitamin C than the recognized vitamin C rich tomatoes to more, it is more than ten times the apple! Chestnut contains a wide range of minerals, potassium, magnesium, iron, zinc, manganese and other content than apples, pears and other common fruit is much higher, especially potassium-containing, than the so-called potassium-rich apple is also 4 times higher The chestnut not only contains a lot of starch, but also rich in protein, fat, B vitamins and other nutrients, heat is also high, chestnut vitamin B1.B2 rich in content, vitamin B2 content of at least 4 times the rice 100 grams also contains 24 mg of vitamin C, which is food can not match. Every 100 grams of protein containing 5.7 grams, 2 grams of fat, carbohydrates 40 to 45 grams, 25 grams of starch. Health chestnut vitamin content can be as high as 40 to 60 mg, cooked chestnut vitamin content of about 25 mg. Chestnut also contains calcium, phosphorus, iron, potassium and other inorganic salts and carotene, B vitamins and other ingredients.
Bitumen Product Description : Bitumen is widely used in the construction of asphalt roads and bituminous membrane products. Bitumen is commonly used to build highways, motorways and rail networks. Bitumen has excellent water-proofing properties and is widely used for making roofing products along with a range of other household and industrial applications, from emulsion paints to sound-proofing. Penetration Bitumen and Bitumen Emulsions are used for the construction of railway tracks and by using special types of bitumen such as Polymer Modified Bitumen, the vibration and noise levels are reduced due to a dampening effect. Bitumen has been proven to be effective on both high-speed railway tracks and heavy load railway tracks. Bitumen is also used for surfacing airfield runways and air strips (PMB is preffered due to its fuel resistant properties) and taxi ways. For the Marine construction industry bitumen is used for hydraulic applications such as canal lining, underwater tunnels, river bank protection, dam construction and sea defences.

APPLICATION OF SK-HB K-SILICATE MORTAR : * K-SILICATE is used for jointing Acid Resisting brick in construction of vessels in suited for construction of fume chambers and stacks handling hot, dry Acid fumes and vapors. It is also used for jointing chemical resisting stoneware pipes. K-SILICATE cement is good bedding material for Acid â?? Resisting bricks and tiles. The concrete surface needed protection should be dryed, clean and rough. The bricks or tiles will be set with K-SILICATE cement over concrete surface applied with a suitable an impermeable interliner. When Bedding and Jointing Materials are the same. On the treated surface bricks or tiles are bedded to a thickness of about 6 mm and tamp gently with a wooden piece till the paste squeezes out of joints. The paste that is squeezed out of the joint should be removed by trowel with good finishing. After the mortar of the joint is dryed treat the joints with 20% Hydrochloric Acid Solution by means of brush. A.R.lining should be always in contact with Acid and not with water. Concrete subtract like Floor, Wall, tanks and similar surface should be protected with a membrane of Bitrok Mastic or compound steel tanks should be protected with rubber or PVC subjected to chemical conditions and temperature of chemical media. The Brick lining is recommended over the protective layer of Bitrok Mastic. When Bedding and Jointing Materials are Different. Spread the silicate type mortar about 6 to 8 mm thick on the back of the tile or brick. Press the tile on the bed leaving required space for joints between tiles for bricks. After the bedding mortar is set, fill Mp the joints with specified cement.PRODUCT DATA SHEET FOR SK-HB ( K-SILICATE) MORTAR A general purpose cement for acid conditions Resistant to High & medium concentrations of most of the common organic and inorganic acids except Hydroflouric acid. Recommended where the concentration of the acid is high suitable for high temperature. Unsuited to aqueous solutions, alkaline conditions. PREPARATIONS OF MORTAR : * Measure 1 part by weight of K-SILICATE solution into a suitable mixing pan. * Add slowly and gradually 3 parts by weight K-SILICATE mortar and mix thoroughly to form a smooth mortar. * In hot season very large batches of mortar will become stiff quite rapidly therefore small batches, not exceeding 4 to 8 kgs. Will be prepared. * The cement mortar will be used before it starts setting.
