Technology description including background system ‘Manufacturing’ starts with stucco preparation (grinding, calcination and separation), followed by expanded perlite and calcite preparation for production. Gypsum mineral (CaSO4 .2H2 O) is grinded and heated to remove 75% of combined water, resulting in the formation of stucco (calcium sulphate hemihydrate) (CaSO4 .½H2 O). After calcination, dry powder is mixed with excess water and any additives. The slurry then cast into moulds and applied as thick slurry to a surface between paper boards. Once it is formed, it is cut automatically with knife mechanism ready to be transferred to dryers to remove the excess water by heating. During this time the plaster solidifies and the plasterboard is then trimmed. Finally, after quality control, the end products are packaged and then dispatched.
