Kamora ho hlahisoa ha mahlale a macha le lihlahisoa tse ncha, mokhoa oa ho felisa 'maraka o tla ntlafatsa boemo bo teng ba tlholisano e sa laoleheng.
(2) Theknoloji e phahameng le lihlahisoa tsa boleng bo phahameng li tlas'a taolo ea linaha tse ling
Indasteri ea kantle ea cellulose ether e qalile pejana, 'me likhoebo tsa tlhahiso tse emeloang ke Dow Chemical le Hercules Group United States li maemong a etelletseng pele mabapi le foromo ea tlhahiso le theknoloji. E thibetsoe ke thekenoloji, lik'hamphani tsa malapeng tsa cellulose ether haholo-holo li hlahisa lihlahisoa tsa boleng bo tlaase tse nang le litsela tse batlang li le bonolo le ho hloeka ha lihlahisoa tse batlang li le tlaase, ha lik'hamphani tse tsoang linaheng tse ling li laola 'maraka bakeng sa lihlahisoa tse phahameng tsa cellulose ether ka ho sebelisa melemo ea theknoloji; ka hona, 'marakeng oa ether oa cellulose oa malapeng, lihlahisoa tse phahameng li hloka ho kenngoa linaheng tse ling le lihlahisoa tse tlaase li na le litsela tse fokolang tsa ho romela thepa. Le hoja matla a tlhahiso ea indasteri ea lapeng ea cellulose ether e eketsehile ka potlako, tlhōlisano ea eona 'marakeng oa machaba e fokola. Ka ntshetsopele ya indasteri ya cellulose ether, meedi ya phaello ya dihlahiswa tse ekeditsweng ka boleng bo tlase e tla tswela pele ho fokotseha, mme dikgwebo tsa lehae di tlameha ho batla katleho ya thekenoloji ho fedisa taolo ya dikgwebo tsa kantle ho naha mmarakeng wa dihlahiswa tsa maemo a hodimo.

K'hothone e hloekisitsoeng, thepa e ka sehloohong e tala eacellulose ether, ke sehlahisoa sa temo. Ka lebaka la liphetoho tikolohong ea tlhaho, tlhahiso le theko li tla fetoha, e leng se tla tlisa mathata ho lokiseng thepa e tala le taolo ea litšenyehelo tsa liindasteri tse tlase.
Ntle le moo, lihlahisoa tsa petrochemical tse kang propylene oxide le methyl chloride le tsona ke lisebelisoa tsa bohlokoa bakeng sa tlhahiso ea cellulose ether, mme litheko tsa tsona li angoa haholo ke ho fetoha ha 'maraka oa oli e tala. Liphetoho tsa boemo ba lipolotiki tsa machaba hangata li na le tšusumetso ho theko ea oli e tala, kahoo baetsi ba cellulose ether ba hloka ho tobana le liphello tse mpe tsa ho fetoha ha theko ea oli khafetsa tlhahisong ea bona le ts'ebetsong ea bona.
