Iimfuno zobugcisa kwiibhotile zeplastiki zokusetyenziswa kweyeza

Iimfuno zobugcisa kwiibhotile zeplastiki zokusetyenziswa kweyeza.Iibhotile zeplastiki zamachiza zenziwe ngokubanzi nge-PE, PP, PET kunye nezinye izinto, ezingonakali lula, ukusebenza kakuhle kokutywinwa, ubungqina bokufuma, ucoceko, kwaye zihlangabezana neemfuno ezikhethekileyo zokupakishwa kweziyobisi.Zingasetyenziselwa ngokuthe ngqo ukupakishwa kweziyobisi ngaphandle kokucoca okanye ukomisa, kwaye zizikhongozeli ezigqwesileyo zokupakisha amayeza.Isetyenziswa kakhulu kumachiza omlomo aqinileyo (afana neetafile, iicapsules, iigranules, njl. njl.) kunye neziyobisi zolwelo lomlomo (ezifana nesiraphu, i-tincture yamanzi, njl.njl.) ukupakishwa, xa kuthelekiswa nezinye izitya zeplastiki ezingenanto zokupakisha iibhotile zeplastiki zonyango zinezininzi ezizodwa. iindawo.

Ibhotile yeplastiki yonyango

1. Umgangatho wokubonakala kweebhotile zeplastiki zonyango: Iibhotile zonyango eziqinileyo zomlomo zihlala zimhlophe.

Iibhotile zamayeza olwelo lomlomo zimdaka ngokubanzi okanye zicace, kwaye zinokuveliswa ngokweemfuno zabathengi beminye imibala yeemveliso, umbala kufuneka ufane, akukho mahluko ucacileyo wombala, umphezulu kufuneka ugudiswe, ugudile, kungabikho deformation icacileyo kunye nemikrwelo, akukho trachoma. , ioli, amaqamza omoya, umlomo webhotile kufuneka ube mpuluswa.

I-2, ukuchonga (1) i-infrared spectrum: i-spectrum ye-infrared yezinto ezisetyenziswe kwimveliso kufuneka ihambelane nemephu yokulawula.(2) Uxinaniso: Ubuninzi beebhotile zeplastiki zonyango bubu: iibhotile zepolyethylene zomlomo eziqinileyo nezilulwelo ezinoxinano oluphezulu kufuneka zibe yi-0.935 ~ 0.965 (g/cm³) Iibhotile zomlomo eziqinileyo kunye ne-liquid polypropylene kufuneka zibe yi-0.900 ~ 0.915 (g/cm³) kunye neebhotile zepolyester ezingamanzi kufuneka zibe yi-1.31 ~ 1.38 (g/cm³)

3, ukutywina: vacuum ukuya kwi-27KPa, gcina imizuzu emi-2, akukho manzi okanye ukugquma ebhotileni.

4. Ukwehla kobunzima beebhotile zeplastiki iyeza lolwelo lomlomo akusayi kudlula i-0.2% ngokwemiqathango yovavanyo;umphunga wamanzi okwaziyo ukungena kwiibhotile zeplastiki zamayeza aqinileyo akusayi kuba ngaphezu kwe-1000mg/24h · L ngokwemiqathango yovavanyo.

5. Ukumelana nokuwa kuwela ngokwemvelo kwindawo ethe tye engqongqo egudileyo ngokwemiqathango yovavanyo, kwaye ayiyi kuphulwa.Olu vavanyo lulinganiselwe kwiibhotile zeplastiki ezixutywe nolwelo lomlomo.

6. Uvavanyo lomothuko Olu vavanyo lulinganiselwe kwiibhotile zeplastiki zamayeza eziluqilima ngomlomo, ekufuneka zifaneleke ngokwemiqathango yovavanyo.

I-7, intsalela evuthayo ngokwendlela yokuvavanya (i-Pharmacopoeia yeRiphabhlikhi yaBantu baseChina, i-2000 edition, iSihlomelo ⅷ N, iSigaba II) uvavanyo, intsalela eseleyo ayiyi kudlula i-0.1% (ibhotile equkethe i-sunscreen evuthayo intsalela ayiyi kudlula i-3.0%).

I-8, i-acetaldehyde njengoko inqunywe yi-chromatography yegesi (i-Pharmacopoeia yeRiphabhlikhi yaBantu baseChina, i-2000, iSihlomelo VE), i-acetaldehyde ayifanele idlule iinxalenye ze-2 ngesigidi, olu vavanyo lukhawulelwe kwiibhotile zeplastiki ze-polyester ngeenjongo zonyango.

9. Ukulungiswa kovavanyo lokunyibilika kwesisombululo sovavanyo lokunyibilika ngokweemfuno zomgangatho, iibhotile zeplastiki zolwelo zolwelo zolwelo lokucaciswa kwesisombululo, isinyithi esinzima, utshintsho lwe-PH, ukufunxwa kwe-UV, ii-oxides ezilula, akukho vavanyo lwezinto eziguquguqukayo, iziphumo kufuneka zihlangabezane neemfuno eziqhelekileyo. ;Iibhotile zeplastiki zomlomo eziqinileyo kufuneka zivavanyelwe kuphela ii-oxides ezilula, isinyithi esinzima kwaye kungabikho kuguquguquka, kwaye iziphumo kufuneka zihlangabezane neemfuno zomgangatho.

I-1O, ibhotile yokuvavanya umbala we-decolorization kufuneka ivavanywe ngokweemfuno eziqhelekileyo, umbala wesisombululo sokuntywiliselwa awuyi kupeyintwa kwisisombululo esingenanto.

I-11, umda we-microbial ngokweemfuno eziqhelekileyo kunye nendlela ye-microbial limit (i-Pharmacopoeia ye-People's Republic of China 2000 version ⅺ Ukuzimisela kweSihlomelo J1, iibhotile zeplastiki zamayeza omlomo we-bacteria, ukungunda, igwele ibhotile nganye ayiyi kuba ngaphezu kwe-100, Escherichia coli Inani lebhaktheriya kwiibhotile zeplastiki kwiyeza eliqinileyo lomlomo aliyi kudlula i-1000, inani lokungunda kunye negwele aliyi kudlula i-100, kwaye inani le-Escherichia coli aliyi kufunyanwa.

12, ubutyhefu obungaqhelekanga ngokomgangatho kwaye ngokomthetho (Pharmacopoeia of the People's Republic of China 2000 version II Isihlomelo ⅺ C) uvavanyo, kufuneka ngokungqinelana nezibonelelo.Ezi zinto zingasentla ngokwemimiselo esemgangathweni yemithetho yokuhlola, kunye ne-cap yebhotile ehambelanayo inokukhethwa ngokweemfuno zezinto ezahlukeneyo, ngokuhambelana nomgangatho kuvavanyo lokuchithwa, uvavanyo olungaqhelekanga lweprojekthi yoluntu, kwaye kufuneka ihambelane nemimiselo. phantsi kokufanelekileyo.Iprojekthi iya kuvavanywa kwaye iya kuthobela izibonelelo phantsi kwenqaku elifanelekileyo.
