Iko kuyerwa chaiko kwemukati medota kwakakosha mumaindasitiri akasiyana anoshandisa cellulose sechinhu chisina kubikwa.Kusarudza zvinyorwa zvemadota zvinopa ruzivo rwakakosha pamusoro pekuchena uye hutano hwe cellulose, pamwe nekukodzera kwayo kune mamwe maitiro.Muchikamu chino, tichaongorora nhanho-ne-nhanho nzira yekuyera nemazvo madota emukati we cellulose.
Muenzaniso Kugadzirira:
Kutanga, tora sampuli inomiririra ye cellulose yekuongorora.Ita shuwa kuti sampuli ine homogeneous uye haina kubva kune chero zvinosvibisa zvinogona kukanganisa kuyerwa.Zvinokurudzirwa kushandisa saizi yakakura yakakwana yekuzvidavirira kune chero kusawirirana mune izvo zvinyorwa.
Pre-Weighing:
Uchishandisa chiyero chekuongorora nehupamhi hwepamusoro, kuyera crucible isina chinhu uye yakachena kana porcelain dish.Nyora uremu nemazvo.Iyi nhanho inosimbisa huremu hwetare uye inobvumira kutsunga kwemukati wedota gare gare.
Kuyera Kuyera:
Chengetedza huremu hunozivikanwa hwesampu yeselulosi mune pre-yakayerwa crucible kana porcelain dish.Zvakare, shandisa chiyero chekuongorora kuti uone huremu hwemuenzaniso nemazvo.Nyora huremu hwesampu ye cellulose.
Ashing process:
Isa iyo yakatakurwa crucible kana ndiro ine cellulose sampu muchoto chemuffle.Choto chemufuremu chinofanirwa kupiswa kune tembiricha yakakodzera, kazhinji iri pakati pe500 kusvika 600 madhigirii celsius.Ita shuwa kuti tembiricha inochengetedzwa mukati mekuita madota.
Nguva yeAshing:
Bvumira sampuli ye cellulose kuti ipinde mumoto wakakwana kana oxidation muchoto chemuffle kwenguva yakafanotemerwa.Nguva yeashing inogona kusiyana zvichienderana nechimiro uye kuumbwa kweiyo cellulose sampu.Kazhinji, kuita madota kunotora maawa akawanda.
Kutonhora uye Desiccation:
Kana ashing yapera, bvisa crucible kana dish kubva muffle furnace uchishandisa tongs woiisa panzvimbo inodzivirira kupisa kuti itonhorere.Mushure mekutonhodza, endesa crucible kune desiccator kudzivirira kunwa hunyoro.Bvumira crucible kuti itonhore kusvika kukamuri tembiricha isati yayera.
Mushure mekuyera:
Uchishandisa chiyero chakafanana chekuongorora, kuyera crucible ine madota asara.Ita shuwa kuti crucible yakachena uye haina chero yakasununguka ash particles.Nyora uremu hwe crucible nemasara edota.
Kuverenga
Kuti uone madota ane madota, bvisa uremu hwehuremu husina chinhu (tare uremu) kubva pahuremu hwemuchinjiko nemasara edota.Kamura huremu hwawanikwa nehuremu hwesampu yeselulosi uye wedzera nezana kuratidza madota emukati sechikamu.
Madota Zvirimo (%) = [(Huremu hweCrucible + Ash Residue) - (Tare Weight)] / (Huremu hweCellulose Sample) × 100
Kunyatsoyera madota emukati we cellulose kwakakosha pakuongorora kunaka kwayo uye kukodzera kwezvishandiso zvakasiyana.Nekutevera nhanho-ne-nhanho nzira inotsanangurwa muchinyorwa chino, munhu anogona kuwana akavimbika uye chaiwo mhedzisiro.Zvakakosha kuchengetedza nekuchenjerera kutonga pamusoro pekuyera, tembiricha, uye nguva yeashing kuti uve nechokwadi chekuyera kwakaringana.Kugaro gadzirisa uye kusimbiswa kwemidziyo kwakakoshawo kuti uve nechokwadi chekuvimbika kwekuongorora.
