Kūlana ʻOihana Laʻau Lapaʻau o ka Lepupalika Lepupalika o Kina—Pono Hoʻopalekana Lapaʻau （YY/T0330-2015）

Ma Kina, ma ke ʻano he ʻano lāʻau lapaʻau, ʻo ka pulupulu hoʻomaʻamaʻa lāʻau lapaʻau i hoʻoponopono ʻia e ka mokuʻāina, ʻo ka mea hana o ka pulupulu lāʻau lapaʻau e pono e hele i ka hoʻāʻo ʻana o ka hoʻokele lāʻau lapaʻau o Kina inā he kūlana hana a me nā lako, pono nā huahana e hana i nā hoʻokolohua lapaʻau a ma hope o ka loiloi loea. e nā ʻāina lāʻau lapaʻau absorbent pulupulu palapala kakau inoa, I mea e ae e hele ma ke kuai.
Ma ka mākeke Kina, pono e hoʻokō ka pulupulu lāʻau lapaʻau me ka Pharmaceutical Industry Standard of the People's Republic of China—Medical Absorbent Cotton （YY/T0330-2015）, ʻo ia ka mea maʻamau e like me kēia, manaʻolana e kōkua iā ʻoe e hoʻomaopopo i nā huahana pulupulu lapaʻau.
1/ E like me ka ʻike maka, pono ke keʻokeʻo a keʻokeʻo paha ka pulupulu lapaʻau i ka nānā ʻana, i haku ʻia me nā fiber me ka lōʻihi ʻaʻole i emi iho ma lalo o 10 mm, ʻaʻole lau, ʻili, ke koena o ke kapa a i ʻole nā ​​mea haumia ʻē aʻe. Aia kekahi kū'ē i ka wā e kikoo ana, ʻaʻole e hāʻule ka lepo i ka wā e haʻalulu mālie.
2/ E like me ka ʻike maka, pono ke keʻokeʻo a keʻokeʻo paha ka pulupulu lapaʻau i ka nānā ʻana, i haku ʻia me nā fiber me ka lōʻihi awelika ʻaʻole i emi iho ma mua o 10 mm, ʻaʻohe lau, ʻili, ke koena o ke kapa a me nā mea haumia ʻē aʻe. Aia kekahi kū'ē i ka wā e kikoo ana, ʻaʻole e hāʻule ka lepo i ka wā e haʻalulu mālie.
Reagent -Zinc chloride iodide solution: e hoʻohana i 10 5mL hoʻohui a i ʻole 0.1 ml wai, e hoʻoheheʻe i 20 g ± 0.5 g zinc chloride, a me 6 5g ± 0.5 g potassium iodide, e hoʻohui i 0.5 g ± 0.5 g kiola ma hope o ka lulu ʻana 15 min, kānana i ka wā pono, e pale i ka mālama māmā.

14/ ʻAʻole ʻeleʻele ka waihoʻoluʻu o ka ʻāpana i loaʻa ma mua o ka hopena kuhikuhi Y5 a me GY6 i kuhikuhi ʻia ma ka Appendix A a i ʻole ka hopena hoʻomalu i hoʻomākaukau ʻia ma ka hoʻohui ʻana i 7. 0mL hydrochloric acid solution (concentrated mass) i 3. 0mL polū kumu. hoʻonā
A e hoʻoheheʻe i ka 0.5 mL o ka hopena i luna i 100 mL me ka solution hydrochloric acid (nui ka nui o 10 g / L).
15/ Ke koena o ka ethylene oxide: inā hoʻomaʻemaʻe ʻia nā huahana pulupulu lapaʻau me ka ethylene oxide, ʻaʻole pono ke koena o ka ethylene oxide ma mua o 10 mg/kg.
16/ Bioload: no ka hoʻolako ʻole ʻana i ka pulupulu hoʻomaʻemaʻe lāʻau lapaʻau, e lepili ka mea hana i ka bioload kiʻekiʻe loa i kēlā me kēia gram o ka huahana i kekahi o nā microbes.
