Izinga Lemboni Yemithi yase-People's Republic of China—Ukotini Omunca Ukwelapha (YY/T0330-2015)

E-China, njengohlobo lwempahla yezokwelapha, ukotini omunca umuthi olawulwa ngokuqinile nguhulumeni, umkhiqizi kakotini omunca umuthi kufanele aphumelele ukuhlolwa kwezwe lonke laseChina lokuphathwa kwezidakamizwa ukuthi kunesimo sokukhiqiza kanye nemishini, imikhiqizo idinga ukwenza izivivinyo zomtholampilo nangemva kokubuyekezwa kochwepheshe. ngamazwe isitifiketi sokubhaliswa komkhiqizo kakotini omunca umuthi, Ukuze uvunyelwe ukuthi udayiswe.
Emakethe yaseShayina, ukotini omunca ezokwelapha udinga ukuthobelana Nezinga Lemboni Yezemithi ye-People's Republic of China—I-Medical Absorbent Cotton (YY/T0330-2015), okuyizinga eliyinhloko ngale ndlela elandelayo, ngithemba ukukusiza uqonde imikhiqizo kakotini yezokwelapha.
1/ Ngokombono obonakalayo, ukotini omunca imithi kufanele ubonakale umhlophe noma ucishe ube mhlophe, owenziwe ngemicu enesilinganiso sobude obungekho ngaphansi kuka-10 mm, ngaphandle kwamaqabunga, ikhasi, izinsalela zejazi lembewu noma okunye ukungcola.Kukhona ukumelana okuthile lapho welula, futhi akukho uthuli okufanele lwehle lapho kuthuthumela kancane.
2/ Ngokubheka okubonwayo, ukotini omunca umuthi kufanele ube mhlophe noma ube mhlophe ngokufana, owenziwe ngemicu enesilinganiso sobude obungekho ngaphansi kuka-10 mm, ngaphandle kwamaqabunga, ikhasi, izinsalela zejazi lembewu noma okunye ukungcola.Kukhona ukumelana okuthile lapho welula, futhi akukho uthuli okufanele lwehle lapho kuthuthumela kancane.
Isixazululo se-Reagent -Zinc chloride iodide: sebenzisa u-10 5mL kanye noma susa u-0.1 ml wamanzi, chitha u-20 g± 0.5 g we-zinc chloride, kanye no-6 5g ±0.5 g we-potassium iodide, engeza u-0.5 g ±0.5 g okhishiwe ngemva kokuzamazama imizuzu engu-15, sefa kudingekile, gwema ukulondolozwa kokukhanya.Isixazululo se-Zinc chloride-formic acid: ncibilikisa u-20 g chloride-0.5 g pound-esixazululweni esingu-8 50 g/L anhydrous formic acid no-80 g plus noma susa 1g.

I-Identification B: Uma ubhekene nesisombululo sesitsha se-chlorination esiyeka umhlalaphansi, i-fiber kufanele ibe nsomi.
I-Identification C: Engeza isixazululo se-chlorinated pot-formic acid engu-10 mL kusampula engu-0.1g, uyishise ibe ngu-4 00C, uyibeke amahora angu-2.5 bese uyinyakazisa ngokuqhubekayo, akufanele incibilike.
3/ Imicu yangaphandle: Uma ihlolwa ngesibonakhulu, kufanele iqukathe imicu kakotini evamile kuphela, evumela imicu emincane yangaphandle ehlukanisiwe ngezikhathi ezithile.
4/ Ifindo likakotini: cishe u-1g wekotini omuncayo wezokwelapha wasakazwa ngokulinganayo kumapuleti ayisicaba angenambala futhi abonisa ngale, ipuleti ngalinye elinendawo engu-10 cmX10cm, inani lama-neps kusampula akufanele lidlule ele-nep evamile (RM) lapho lihlolwa. ngokukhanya okudluliselwayo.
5/ Incibilika emanzini: thatha 5. 0g kakotini omuncayo, uwufake emanzini angama-500 mL bese uwabilisa imizuzu engama-30, uwunyakazise ngezikhathi ezithile bese ufaka ukuhwamuka.
Inani lamanzi alahlekile.Thela ngokucophelela uketshezi.Khama uketshezi olusele kwisampula ngenduku yengilazi bese uluxuba noketshezi olutheliwe ngesikhathi kushisa kuhlunga.I-400 mL ye-filtrate yahwamuka (ehambisana no-4/5 wesisindo sesampula) futhi yomiswa ku-100 ℃ ~ 105 ℃ kuya esisindweni esingaguquki.Bala iphesenti lensalela kusisindo sesampula sangempela.Isamba sento encibilikayo emanzini akufanele ibe ngaphezu kuka-0.50%.
6/ Ph: I-Reagent - isixazululo se-phenolphthalein: ncibilikisa i-0.1 g ± 0.01g phenolphthalein ku-80 mL isixazululo se-ethanol (ingxenye yevolumu engu-96%) bese unciphisa ku-100 mL ngamanzi.Isixazululo se-Methyl orange: 0.1g ± 0.1g methyl orange yancibilika emanzini angama-80 mL futhi yahlanjululwa yaba ngu-100 mL ngesisombululo se-ethanol esingu-96%.
Isivivinyo: Isixazululo esingu-0.1 ml se-phenolphthalein sengezwe ku-25 ml yokuhlola isixazululo S, i-0.05 yengezwe kwesinye isixazululo sokuhlola esingu-25 ml SML methyl orange solution, bheka ukuthi isixazululo sibonakala sipinki.Isixazululo akufanele sibonakale pink.
7/ Isikhathi sokucwila: isikhathi sokucwila akufanele sidlule imizuzwana eyi-10.
8/ Ukumuncwa kwamanzi: ukumuncwa kwamanzi kwegramu ngayinye yokotini omunca imithi akufanele kube ngaphansi kuka-23.0g.
9/ Into encibilikayo ku-ether: inani eliphelele le-ether akumele libe likhulu kuno-0.50%.
10/ I-Fluorescence: ukotini omunca umuthi kufanele ube yi-microscopic ensundu kanye ne-fluorescence onsomi kanye nenani elincane lezinhlayiya eziphuzi.Ngaphandle kwemicu embalwa ehlukanisiwe, akukho okufanele kubonise i-fluorescence eqinile eluhlaza okwesibhakabhaka.
I-11/ Ukomisa ukuncipha kwesisindo: ukuncipha kwesisindo akufanele kube kukhulu kune-8.0%.
12/ Sulfate ash: Umlotha wesulfate akufanele ube mkhulu kuno 0. 40%.
I-13/ Into esebenzayo ebusweni: igwebu lezinto ezisebenzayo akufanele limboze yonke indawo ewuketshezi.
14/ Into enemibala evulelekayo: Umbala wokukhishwa okutholiwe akufanele ube mnyama kunesixazululo sereferensi esingu-Y5 ne-GY6 esicaciswe ku-Appendix A noma isixazululo sokulawula esilungiswe ngokwengeza u-7. 0mL isixazululo se-hydrochloric acid (isisindo esigxilile) sibe ngu-3. 0mL oyinhloko eluhlaza okwesibhakabhaka isisombululo
Futhi hlambulula u-0.5 mL wesisombululo esingenhla ku-100 mL ngesisombululo se-hydrochloric acid (isisindo sokugxila esingu-10 g/L).
15/ Izinsalela ze-Ethylene oxide: uma imikhiqizo kakotini yezokwelapha inzalo nge-ethylene oxide, insalela ye-ethylene oxide akufanele ibe ngaphezu kuka-10 mg/kg.
16/ I-Bioload: ngokunikezwa okungeyona inzalo ukotini omuncayo wezokwelapha, umenzi kufanele alebule inani eliphakeme le-bioload ngegremu lomkhiqizo elinye lenani lamagciwane.
