Industrial Production Of Precipitated Silica & Calcium Carbonate & Neoprene Rubber

1) Industrial Production Of Precipitated Silica 

Www.industrialchemistry.com

>  Reaction

Na²Sio³ + H²So4  ------> Na²So4 + Sio²
Sodium   Sulphuric       Sodium  Silica
Silicate    Acid                 Sulphat
                         
                                           +H²O
                                           Water

>  Process

- Precipitated silica is produced by a reation of the sodium silicate & sulphuric acid .

- First of all pure sodium silicate is taken in dilution tank, whare it is diluted by water.

- Now dilution of solution is taken in a reactor in the reactor H²So4 is also added.

- Solution in the reactor is heated by steam a reaction take place between sodium silicate & Sulphuric acid

- Now afrer complition of reaction whole mass is take in filter press to remove sulphate based on compound & give washed of water.

- Tretment mass is drying in sundrying when filter dryed in tray drayer. then pulveriser the mass & packed pure precipitation silica.

>  Application

1]  Filter softner & performance improvement in rubber & plastic.

2] Cleaning, thickening & polishing agent in toothpaste for oral health care.

3] Food processing & pharmaceutical additive as anti caking, thickening agent, absorbent to make liquid in powders.

4] Food rheology modifier.

5] Defoamer.



2)  Industrial Production Of CaCo³



Www.industrialchemistry.com


> Reation

CaCl² + Na²Co³ ----> CaCo³ + 2NaCl

> Process

- Calcium carbonate is production by the reation of calcium chloride & sodium carbonate.

- First of all calcium chloride & sodium carbonate both taken in a reation.

- Solution in the reactor heated by the steam reation taken place between CaCl² & Na²Co³.

- The reactor will be attucbed to jacket & also the agitator are mixing the whole mass in reactor.

- the remaining mass will be taken in filter press in the filter press remove of NaCl by a washing of H²O.

- Then the whole mass will be taken of the tray drayer & the pulverised of the product are packed.

>  Uses

1 ) The main use of clcium carbonate is in the construction industry material & limestone.

2 ) Calcium carbonate is also used in the prification of iron from are in a blast furace.
  3)  Industrial Production Of Neoprene Rubber

Www.industrialchemistry.com

> Prosecc

- Neoprene rubber is manufactured from the chloroprene

- First of all chloroprene & pyrogallol are taken in stabilizer after it is taken in polymerisation takn here woden pulp, sulphar, NaoH, K²S²O8, & sodium salt of napthalene, sulfonic acid are added.

- Here polymerisation takn place at 40 C in the presence of equal amount of water.

- After complotion of reation whole mass taken in plasticizer here tetra ethyl thiuram di-sulphide is added to increase plasticity & stabilization of polymer.

- Alkali-latex is taken in coagulation tank here coagulation is done is done by acetic acid.

- Now coagulation mass is further taken in brine cooled drum for freezing coagulation & then thin film of the compund is washed by water i have washing tank to remove some impurities, now drayer the mass & 120°C in dry & dyamass is further taken in polymeriser reactor, here alkli mercaptan is added to control the size of polymer.

- Now ploymeric mass is charge in vulcanization unit & valcanization is completed with sulphar in the presence magnesium axide (MgO),zinc oxid (ZnO) as vulcanizing agent cool the mass & cooler & stored as in neoprene rubber.

Types of rabbur and information about it.

 Rubber is a name of a matenrial which come Strate & Shrinkage. - Rubber is a polymer either peroduced by a natural Source Can be synthesis on an industusial scale. - Rubbeut is also known as elastomer is a high Polymeulr having elastic propenties. - Elasticity & rabberness is the most important Properties of rubber. - on strching it elongate to nearly 200% of its original dimentational &  quickely reaction to it's original Shape when Strching fouice is a remove. >   Importance of application of ruubber  properties of rubber(natural & synthetic rubber) 1)  Grood tensile Strength. 2) High flexibility 3) good electrical resistance 4) good chemical resistance 5) good Abrasion resistance 6) good resilience 7) high elasticity 8) low condudivity 9) low permeability to air, grases & Liquids. - Rubber are use manufacture of large no. of puroducts such as, tyres, v-belts, conveyor belts rubber lined tanks, m...

M.sc Sem-2 Manufacturing Of Glass & Types Of Glass And Information About It

                   >  Process - Glass are made by heating mixtune that nearly always consist of silica call & dry powder or metallic oxides. - Most glass are manufactun by a process in which raw-mateutials are converted at high temperature to a homogejeaus melts , that is then form in to an article. -  Raw mateutials are selecting acrourding the properties purity supply, cost etc . - Silica sand is most common in goradiant all most type of glasses.  - limp-Stones is a sourvr of colcium soda ash is Source of Sadium and bore and Boutic acid is Source of borone. - Broken gloss Usually termed as collected is used as a batch material to enhance glass melting and to resuce the amount of dust and other particular matter that aften a companies a batch mads exculsively from fresh raw-mateuial. - Tipically 10 to 151% of glass batch is the comprised of collect. - More efficient of operation as used in the c...

Industrial Production of MgSo4,CaSo4, Mg(OH)² & MgCo³ & Na²Sio³

1)  Industrial production of MgSo4,CaSo4, Mg(OH)² > Reaction                                     1)  Mgcl² + Ca(OH)²  ----->  Mg(OH)² +                                                            CaCl² 2)  Cacl² + H²So4  ------>  CaSo4 + 2HCL 3)  MgCl² + H²So4 ------> MgSo4 + 2HCL > Process  - In the industrial production of MgSo4 & CaSo4 first of all mixed salt bittern is first taken in a reactor. - Ca( OH)² from line treatment tank is also charge into the reactor. - Due to reactor precipitation of the Mg(OH)² is obtained. - filter the mass in filter press to remove precipitation of Mg(OH)² which is dry pulverised & packed. - Filtrate is further taken in a trea...
