Inganda zikora imiti Igipimo cya Repubulika y’Ubushinwa - Ubuvuzi bwa Absorbent Pamba （YY / T0330-2015）
Mu Bushinwa, nk'ibikoresho byo kwa muganga cotton ipamba yinjira mu buvuzi igenzurwa cyane na Leta, uwakoze ipamba yinjira mu buvuzi agomba gutsinda ibizamini by’ubuyobozi bw’ibihugu by’Ubushinwa niba bifite umusaruro n’ibikoresho, ibicuruzwa bigomba gukora ibizamini by’amavuriro na nyuma yo gusuzuma impuguke. n'ibihugu ubuvuzi bwinjiza ipamba ibicuruzwa byanditse, Kugirango yemererwe kugurishwa.
Ku isoko ry’Ubushinwa, ipamba yinjira mu buvuzi igomba gukurikiza amahame y’imiti y’imiti ya Repubulika y’Ubushinwa - Ubuvuzi bwa Absorbent Cotton （YY / T0330-2015）, amahame ngenderwaho nkaya akurikira, yizeye kugufasha gusobanukirwa n’ibicuruzwa by’ipamba by’ubuvuzi.
1 / Ukurikije uko bigaragara, ipamba yinjira mu buvuzi igomba kuba yera cyangwa quasi-yera mu bigaragara, igizwe na fibre ifite uburebure buri hagati ya mm 10, idafite amababi, ibishishwa, ibisigazwa by'imbuto cyangwa ibindi byanduye. Hariho ukurwanya runaka iyo kurambuye, kandi nta mukungugu ugomba kugwa mugihe uhinda umushyitsi.
2 / Ukurikije uko bigaragara, impamba yinjira mu buvuzi igomba kuba yera cyangwa quasi-yera mu bigaragara, igizwe na fibre ifite uburebure buri hagati ya mm 10, idafite amababi, ibishishwa, ibisigazwa by ikoti ryimbuto cyangwa ibindi byanduye. Hariho ukurwanya runaka iyo kurambuye, kandi nta mukungugu ugomba kugwa mugihe uhinda umushyitsi.
Reagent -Zinc chloride iyode yumuti: koresha 10 5mL wongeyeho cyangwa ukuyemo amazi 0.1 ml, ushonga 20 g ± 0.5 g zinc chloride, na 6 5g ± 0.5 g iyode ya potasiyumu, ongeramo 0.5 g ± 0.5 g usohokanye nyuma yo kunyeganyeza 15 min, kuyungurura iyo ngombwa, irinde kubungabunga urumuri. Zinc chloride-acide acide: gushonga 20 g chloride-0,5 g pound-mumuti wa 8 50 g / L acide formic acide hamwe na 80 g wongeyeho cyangwa ukuyemo 1g.
Kumenyekanisha A: iyo urebye munsi ya microscope, buri fibre igaragara igomba kuba igizwe na selile imwe igera kuri 4cm z'uburebure na 40μm z'ubugari, hamwe n'umuyoboro mwinshi, uzengurutswe n'uruzitiro, ubusanzwe uhindagurika.
Kumenyekanisha B: Iyo uhuye nibisubizo bya chlorination yamashanyarazi, fibre igomba kuba yijimye.
Kumenyekanisha C: Ongeramo 10 mL ya chlorine pot-formic acide kuri 0.1g sample, shyushya kuri 4 00C, uyishyire kuri 2.5 h hanyuma uyinyeganyeze ubudahwema, ntigomba gushonga.
3 / Fibre yo mumahanga: Iyo isuzumwe munsi ya microscope, igomba kuba irimo fibre isanzwe gusa, bigatuma rimwe na rimwe utuntu duto duto two mu mahanga twitaruye.
4 / Ipfundo ry'ipamba: ipamba igera kuri 1g ivura imiti yakwirakwijwe mu isahani 2 idafite ibara kandi ibonerana, buri sahani ifite ubuso bwa cm 10X10cm, umubare wa neps murugero ntugomba kurenza uw'ibisanzwe (RM) mugihe wasuzumwe n'umucyo woherejwe.
5 / Gushonga mumazi: fata 5. 0g ipamba ikurura, uyishyire mumazi 500 mL hanyuma ubiteke muminota 30, ubyuke rimwe na rimwe hanyuma wuzuze umwuka.
Umubare w'amazi yatakaye. Witonze usuke amazi. Kata amazi asigaye kurugero ukoresheje inkoni yikirahure hanyuma ubivange namazi yasutswe mugihe ashyushye. 400 mL ya filtrate yahumutse (ihwanye na 4/5 bya misa y'icyitegererezo) hanyuma yumishwa kuri 100 ℃ ~ 105 ℃ kugirango uburemere buhoraho. Kubara ijanisha ryibisigisigi kuri sample nyayo. Umubare wibintu byose byashonga mumazi ntibigomba kurenza 0.50%.
6 / Ph: Reagent - igisubizo cya fenolphthalein: gushonga 0.1 g ± 0.01g fenolphthalein muri 80 mL ya Ethanol (agace kangana na 96%) hanyuma ukayungurura kugeza kuri mL 100 n'amazi. Methyl orange igisubizo: 0.1g ± 0.1g orange methyl orange yashongeshejwe mumazi 80 mL hanyuma ikavangwa kugeza kuri 100 mL hamwe na 96% ya Ethanol.
Ikizamini: 0.1 ml ya fenolphthalein yongewemo muri 25 ml yumuti wibizamini S, 0.05 yongewe mubindi bisubizo bya ml 25 ya SML methyl orange igisubizo, reba niba igisubizo gisa nijimye. Igisubizo ntigikwiye kugaragara.
7 / Igihe cyo kurohama: igihe cyo kurohama ntigomba kurenga 10 s.
8 / Kwinjiza amazi: kwinjiza amazi kuri buri garama yipamba yinjiza imiti ntigomba kuba munsi ya 23.0g.
9 / Ikintu gikemuka muri ether: igiteranyo cyibintu byose byashonga muri ether ntigomba kurenza 0.50%.
10 / Fluorescence: ipamba yinjira mubuvuzi igomba kuba gusa microscopique yijimye na fluorescence yumutuku hamwe nuduce duto twumuhondo. Usibye fibre nkeya yihariye, oya ntigomba kwerekana fluorescence ikomeye y'ubururu.
11 / Kuma ibiro byumye: gutakaza ibiro ntibigomba kurenza 8.0%.
12 / ivu rya sulfate: ivu rya sulfate ntirishobora kurenza 0. 40%.
13 / Ubuso bukora neza: ifuro ryibintu bikora ntibigomba gutwikira hejuru yamazi yose.
14 / Ibara rishobora kumeneka: Ibara ryibikomokaho ntirishobora kuba umwijima kurenza igisubizo cya Y5 na GY6 cyerekanwe kumugereka A cyangwa igisubizo cyo kugenzura cyateguwe wongeyeho 7. 0mL acide hydrochloric acide (misa yibanze) kuri 3. 0mL ubururu bwibanze igisubizo
Kandi ugabanye 0.5 mL yumuti wavuzwe haruguru kuri 100 mL hamwe numuti wa hydrochloric aside (ubunini bwa 10 g / L).
15 / Igisigisigi cya Ethylene: niba ibikomoka ku ipamba byubuvuzi byatewe na okiside ya Ethylene, ibisigisigi bya okiside ya Ethylene ntibigomba kurenza mg / kg 10.
16 / Bioload: kugirango itangwe neza na pamba yinjira mubuvuzi, uyikora agomba gushyiramo bioload ntarengwa kuri garama yibicuruzwa bimwe mubitigiri bya mikorobe.
