(1) Ho sebetsa pele

Li-elbows li lokela ho hlahlojoa ka bonngoe, ‘me ponahalo le boholo bo fapaneng bo lokela ho felisoa haeba litekanyetso tsa lipeipi tsa tšepe li sa finyelloe; acetone le li-solvents tse ling tsa manyolo li lokela ho sebelisoa ho hloekisa bokaholimo ba likhama tse mafura; litsoe tse rometsoeng ke leoatle li lekoa bakeng sa chloride Haeba litaba li feta 20mg/m2, li hlatsoe ka metsi a hloekileng a khatello e phahameng.

(2) Ho thunya le ho senya

Setsoe se tsamaea holim’a mohala oa phetisetso ea sebopeho sa selikalikoe ‘me se kena ka phaposing ea ho hloekisa bakeng sa ho phatloha le ho tlosa mafome.

(3) Tlhahlobo le phekolo ka mor’a ho tlosoa ha mafome

Mohato oa pele ke ho etsa tlhahlobo ea pono ho lokisa kapa ho tlosa liphaephe tsa tšepe tse nang le bothata. Ho feta moo, sesebelisoa sa ho metha mohala oa ankora se tla sebelisoa ho bona botebo ba mohala oa ankora ho latela makhetlo a behiloeng a tlhahlobo. Qetellong, boemo ba ho tlosa mafome bo tla hlahlojoa ho latela foto kapa sampole ea papiso ea kereiti.

Likarolo tse ka hare le tse ka ntle li fafatsoa ka tatellano, ‘me ho fafatsa ka ntle ho tlameha ho etsoa pele lera le ka hare le kenngoa ka gelatinized.

(6) Ho pholisa metsi

E tlameha ho netefatsoa hore ho roala ho folisitsoe ka ho feletseng pele metsi a pholile.

(7) Tlhahlobo ea Inthaneteng

Ha mocheso oa holim’a setsoe o le ka tlase ho 100 ° C, ho sebelisoa mochine o thibelang ho lutla ha tlhase ho bona ho lutla holim’a likoti tsohle, ‘me ho lutla ho tlameha ho tšoauoa le ho lokisoa ho latela maemo a nepahetseng ka mor’a hore e se ke ea sebetsa.
