Methyl acetate le ethyl acetate ke ditharollo tse pedi tse tsebahalang tse sebediswang haholo diindastering tse fapaneng tse kang dipente, dikobo, dikhomaretsi le meriana. Thepa ya tsona e ikgethang ya dikhemikhale le mesebetsi ya tsona di etsa hore di be bohlokwa haholo ditshebedisong tse ngata, ka hona di kganna tlhokeho ya tsona mmarakeng.
E tsebahala ka ho fetoha ha mouoane ka potlako le chefo e tlase, methyl acetate e sebetsa e le tharollo e sebetsang bakeng sa nitrocellulose, li-resin le li-polymer tse fapaneng. Tshebetso ea eona ha e felle feela mesebetsing ea ho qhibilihisa; e boetse e sebelisoa ho hlahisa li-derivatives tsa methyl acetate, tse sebelisoang tlhahisong ea lik'hemik'hale tse ikhethang. Ka lehlakoreng le leng, ethyl acetate e ratoa ka lebaka la monko oa eona o monate le ho qhibiliha ho babatsehang, e leng se etsang hore e be khetho e tsebahalang indastering ea lijo le lino bakeng sa tlhahiso ea linoko le monko o monate.
Boleng ba ditharollo tsena bo bohlokwa kaha bo ama ka ho toba tshebetso ya sehlahiswa sa ho qetela. Methyl acetate e hlwekileng haholo le ethyl acetate di bohlokwa bakeng sa ditshebediso tse hlokang maemo a thata a boleng, jwalo ka meriana le tshebetso ya dijo. Bahlahisi ba ntse ba tsepamisa maikutlo haholo tlhahisong ya ditharollo tsa boleng bo hodimo ho fihlela ditlhoko tse ntseng di hola tsa diindasteri tsena.
Mabapi le litheko, litheko tsa methyl acetate le ethyl acetate li fetohile ka lebaka la liphetoho litšenyehelong tsa thepa e tala le matla a 'maraka. Mekhoa ea litheko e susumetsoa ke lintlha tse kang bokhoni ba tlhahiso, liphetoho tsa taolo, le likhetho tse fetohang tsa bareki. Ha botsitso bo ntse bo fetoha ntlha ea bohlokoa indastering ea lik'hemik'hale, 'maraka o ntse o fetohela butle-butle ho ea ho li-solvents tse thehiloeng ho bio, tse ka amang theko le tlhoko ea li-acetate tsa setso.
Ka kakaretso, 'maraka oa methyl acetate le ethyl acetate o lebelletsoe ho hola, o susumetsoa ke ho tenyetseha ha oona le tlhoko e ntseng e hola ea litharollo tsa boleng bo holimo ho pholletsa le liindasteri tse fapaneng. Ha mekhoa ea 'maraka e ntse e fetoha, bankakarolo ba tlameha ho lula ba falimehile ho ikamahanya le liphetoho lithekong le likhethong tsa bareki ho netefatsa hore ba boloka monyetla oa tlholisano tikolohong ena e fetohang.
