Patlo ea litšoantšo ke ts'ebetso e bonolo le e rarahaneng e hlokang ho khethoa ka hloko tsa lisebelisoa ho netefatsa poloko le botšepehi ba likotoana tsa bonono. Ethen e-nts'etsopele ea selefounu, e fumane lisebelisoa indastering ea bona e fapaneng, ho kenyelletsa le ho boloka metsi, ho tsitsipana le ho boloka metsi. Sebakeng sa ho boloka litšoantšo tsa bonono, polokeho eaENDE ENSEke ho hlahloba lintho tse boima. Kakaretso ena e felletseng e hlahloba likarolo tsa ts'ireletso ea Se-e-le Clishe, tse shebileng mathung (HPML HYDROXYLL.
1. HydroxypropyL methylcelllll (HPMC)
a. Ts'ebeliso e Tloaelehileng
HPMC e sebelisoa khafetsa molemong oa thepa ea eona ea metsi a metsi. Boemo ba eona bo khethollang bo etsa hore ho be loketse ho theha merabe le bana ba molumeli ho tsosoloseng litsebi tsa pampiri.
b. Mehopolo ea Ts'ireletso
HPMC ka kakaretso e nkuoa e le eona e sireletsehileng bakeng sa poloko ea litšoantšo ha e sebelisoa ka botsitso. Ho lumellana ha eona ka lintho tse fapaneng le katleho ea eona ha li boloka botšepehi ba lipapatso tsa lipampiri li kenya letsoho tikolohong ea lefapha.
2. Ethyl hydroxethyl cellulosese (Ehec)
a. Ts'ebeliso e Tloaelehileng
Ehec ke selefounu e 'ngoe e sebelisitsoeng ho boloka thepa ea eona e tobatsang le e tsitsitseng. E kanna ea sebetsa ka mekhoa e fapaneng ho fihlela litšobotsi tse lakatsehang.
b. Mehopolo ea Ts'ireletso
E tšoana le HPMC, Ehec e nkuoa e sireletsehile bakeng sa lits'ebetso tse itseng tsa ho boloka thepa. Tšebeliso ea eona e lokela ho hokahana le litlhoko tse ikhethileng tsa bonono 'me u be le tlhahlobo e phethahetseng ea ho netefatsa ka mokhoa o nepahetseng.
3. CmboxyMethyl cellulose (cmc)
a. Ts'ebeliso e Tloaelehileng
CMC, ka thepa ea eona e tobatsang ebile e tsikitlanya thepa, e fumana kopo indastering e fapaneng, ho kenyeletsa le phutuho. E khetholloa ho latela bokhoni ba eona ho fetola pono ea tharollo.
b. Mehopolo ea Ts'ireletso
Cmc ka kakaretso e nkuoa e le eona e bolokehileng bakeng sa merero e tobileng ea poloko. Profile sa eona sa polokeho e etsa hore e be e loketseng tšebeliso ea maikutlo ka litlhahiso tse reriloeng ho hlakisa le ho sireletsa litlatsetso tse sireletsehileng.
4. Mekhoa e metle
a. TLHOKOMELISO
Pele ba kenya chelete e 'ngoe le e' ngoe ea bonono ho ea ho bala Bohato bona bo tiisa hore boitsebiso bo lumellana le mosebetsi oa bonono ebile ha bo na litlamorao tse mpe.
b. Tlhahlobo
Litšireletso tsa bonono le litsebi li bapala karolo ea bohlokoa ho khethollang thepa e loketseng le mekhoa e loketseng ea ho boloka. Setsebi sa bona se tataisa khetho ea Ethena ea Cellu Bohla-bo-mme le lisebelisoa tse ling ho fihlela sephetho sa tlhahlobo ea litaba.
5. Ho latela tumellano
a. Ho latela melao ea maemo
Ho boloka mekhoa ea ho bakoe ho kopanya le litekanyetso le litataiso tse ikhethang ho netefatsa boemo bo phahameng ka ho fetisisa ba tlhokomelo ea mesebetsi ea bonono. Ho khomarela litekanyetso tsena ho bohlokoa ho boloka polokeho le botšepehi ba ts'ebetso ea ho phunya.
6.conclusion
cellulose ethers such as HPMC, EHEC, and CMC can be considered safe for the conservation of artwork when used in accordance with best practices. TLHOKOMELISO, ho buisana le litsebi tse nang le litsebi, 'me ho latela melao ea ho tiisa ho netefatsa polokeho le katleho ea li-celdoug. Ha tšimo ea bosholu ba thepa e fetoha, lipatlisiso tse sa feleng, lipatlisiso tse tsoelang pele har'a litsebi li tlatsetsa linthong tse tšepahalang tsa ho boloka lefa la tsona le tšepahalang.
