caustic soda flake 96

A, refinement petroleum. After sulfuric acid wash away dirt, the petroleum product also implies some acidity materials to oxidize sodium aqua rinse with the hydrogen, is washed by water again, so as to get a refined product. Two, print to dye Mainly used for indigo to fasten dyestuff and Mao to fasten dyestuff.Restoring dyestuff dyeing in the process and wanting first to restore it as concealed color body with caustic soda aqua and insurance powder is sour, dye empress again oxidize with the oxidizing agent originally don't dissolve sex status. The cotton textiles is after using caustic soda aqua the processing canned remove to overaly in the materials, such as the La quality on the cotton textiles, grease and starch...etc., can increase the silk of fabric at the same time light color and luster, make to dye more even. Three, spin and weave a fiber 1.Spin and weave The cotton, hemp spins and weaves a thing to oxidize sodium(caustic soda) aqua with the thick hydrogen processing to improve fiber function.Being synthetic fiber is like artificial cotton, artificial hair, rayon etc., mostly glue fiber, they are to oxidize the sodium, carbon disulfide(CS2) as raw material with the cellulose(is like pulp), hydrogen, make into a glue liquid, through spray silk, condense but make. 2, glue fiber Want to use 18 20% caustic soda aquas to immerse Zi cellulose first, make it becomes alkali cellulose, then is dry the alkali cellulose and smashes and adds carbon disulfide again, finally use a sparse alkali liquid chase Huang sour salt deliquescence, have to a glue liquid.Again has been filter, taken out vacuum(go to bubble), can in order to draw thread. Four, deckle The raw material of deckle is timber or grass plant, these plant inside in addition to containing cellulose, also imply a nice bit of non- cellulose.(wood quality vegetable, resin etc.)The hydrogen oxidizes a sodium to used for taking off a wood vegetable and only takes off in addition to the wood quality in the timber is plain so as to get a fiber.Joining sparse hydrogen to oxidize sodium aqua can non- cellulose the composition fuse but separate and make thus can the cellulose is the pulp of main composition. Five, chemical engineering and chemistry try. In the chemical industry, make metal sodium, electrolysis water to all want to use caustic soda.Many productions that have no machine salt especially make some sodium salts(is like borax, Huo sour sodium, phosphoric acid sodium and heavy chrome sour sodium, and sulfurous acid sodium...etc.) to all want to use the caustic soda or the pure alkali.Synthesize dyestuff, medicine and organic middle body etc. to also want to use the caustic soda or the pure alkali. (A),Plastics 1, polycarbonate(PC) Light spirit+the hydrogen oxidize a sodium+two chlorine methanes 2, gather ammonia ester(PU) The alkali solution recalls process convenient caustic soda. 3, the epoxy of Fen Quan Wreath oxygen compound and line type Fen Quan the resin oxidize a sodium catalyst in the hydrogen the bottom shrinks to gather but becomes of a type of resin. 4, the bran Quan benzene Fen resin Bran Quan and benzene Fen shrink to gather born two priceses hot solid living resin, respond process with the hydrogen oxidize a sodium for catalyst. 5, gather ethylene Chun production line is oxidized sodium aqua, carbonic acid potassium or other hydroxide catalysts with the hydrogen. 6, water-soluble resin of Fen Quan 40% hydrogens oxidize sodium aqua+37% formaldehydes systems (Two)Make a medicine Stomach medicine:The composition has hydrogen to oxidize aluminum, hydrogen to oxidize magnesium, baking soda and jot hydrogen to oxidize a sodium, the main function is to moderate stomach acid Zui A radicle cellulose sodium(CMC):The food, drugs emulsify, glue to answer, become a film.Is an anti- dirty mark in the rinse the deposition is again.The refined cotton and NaOH responds to make into the one-step method ether of alkali cellulose, empress and chlorine acetic acid turns to respond to make. Six, metallurgy, electroplate In the metallurgy industry, usually want to change the effective composition in the mineral stone into the sodium salt of dissolubility, so that the obviation don't dissolve sexual impurities among them, therefore, often need to join pure alkali(it again is help a Rong), sometimes also use caustic soda. 1.Make aluminum and oxidize aluminum During the Ye chain of the aluminum, use of the making of the ice crystal stone and the processing of the aluminum soil mineral, all want to use the pure alkali and the caustic soda.Make to oxidize the aluminum NaOH aqua to heat to dissolve an aluminum soil mineral in of oxidize aluminum, get aluminum sour sodium aqua.Aqua and remnant(red mire) lower temperature after separating and join hydrogen to oxidize aluminum to make crystal kind of, Be mixed blend by long time, the aluminum sour sodium cent analyzes a hydrogen to oxidize aluminum and washes clearly, and in 950 under 1200 temperatures the Ya burn and have to oxidize aluminum finished product.The Xi hydrogen oxidizes aqua in aluminum to be called mother liquid, evaporate concentrated behind circularly use.Because the crystallize of three water aluminum stones, one water soft aluminum stone and one water hard aluminum stone constructs a dissimilarity, they have very great difference in the deliquescence function in the Ke sodium aqua, so want to provide a dissimilarity of dissolve a condition, it is mainly different to dissolve a temperature.Three aluminum soil minerals can dissolve under 125 140 , one water hard aluminum stone type aluminum soil the mineral then want in 240 260 and add the condition of lime(3 7%) under dissolve. 2.Chain Wu Ye chain Wu, also first after baking Jing mineral and pure alkali to burn into the Wu sour sodium that can dissolve, again through sour processes, such as Xi, dehydration and revivification...etc. but make powder-like in shape Wu of. 3.Electroplate. The caustic soda electroplates to electroplate aqua and have the function of conductor in conduct and actions in the hardware! Seven, other functions 1.The porcelain and ceramics caustic soda makes in the porcelain and ceramics of the function have 2:00, the first, make process in the burning of porcelain and ceramics in, the caustic soda is a dilution.The second, burning to make good porcelain and ceramics surface will have already rowed a scar or very rough, after cleaning with the caustic soda aqua, make porcelain and ceramics surface be getting smoother. 2.The instrument industry is used to sour moderate, take off a color and take off a smelly.The gum glues industry to used to a starch paste to turn and moderate.Can make the going to of Gan Jie, and peach...etc. skin and take off a color, take off a smelly...etc.
