Focus on Cellulose ethers

Khoutu ea likarolo tsa cellulose ether le litlhoko tsa tekheniki

Cellulose ke sesebelisoa se matla ka ho fetisisa se ka nchafatsoang lefatšeng ka bophara. E tsoa ho limela tse tala tsa lefats'e le tlas'a metsi 'me ke karolo ea mantlha ea marako a lisele tsa limela. Ntle le palo e nyane ea libaktheria tsa liphoofolo le lintho tse phelang metsing, cellulose e fumaneha haholo limela tse tala. Ka photosynthesis, limela li ka kopanya cellulose ea 155Gt ka selemo, eo 150Mt e tsoang ho limela tse phahameng; lehong pulp cellulose e ka bang 10Mt; cellulose ea k'hothone 12Mt; lik'hemik'hale (grade ) 7Mt ea selulose, ha palo e kholo ea lehong (e ka bang 500Mt ea selulose) e ntse e sebelisoa e le mafura kapa lesela.
Selulose ea tlhaho e fapana ka bohloeki. Cotton ke tlhale ea semela e nang le selulose e ngata ka ho fetisisa tlhahong, 'me selulose ea eona hangata e ka holimo ho 95%. Lijo tse telele tsa k'hothone li sebelisoa ka tloaelo tlhahiso ea masela. Fiber e khuts'oane e bitsoa Linter pulp, e leng thepa e tala ea bohlokoa bakeng sa tlhahiso ea indasteri ea lihlahisoa tsa cellulose.
