Kwatancen Ayyuka na PP da HDPE, Abubuwan Raw Abubuwan Da Aka Fi Amfani da su don kwalabe na Reagent

Tare da ci gaba da fadada iyakokin aikace-aikacen kayan aikin polymer daban-daban, kwalabe na reagent na filastik a hankali an ƙara yin amfani da su a cikin ajiyar kayan aikin sinadarai.Daga cikin albarkatun kasa don samar da kwalabe na filastik reagent, polypropylene (PP) da polyethylene mai girma (HDPE) sune kayan da aka saba amfani da su.To mene ne bambancin aiki tsakanin waɗannan kayan biyu?

1)TdaularRmisali

Matsakaicin zafin jiki na HDPE shine -100 ° C kuma na PP shine 0 ° C.Don haka, lokacin da samfuran ke buƙatar ajiyar ƙananan zafin jiki, kwalabe na reagent da aka yi da HDPE sun fi fifiko, kamar 2-8°C buffers da ake amfani da su don adana reagents na bincike.kwalabe na Reagent don Buffer da -20 ° C enzyme;

2) ChemicalRmisali

kwalabe na Reagent da aka yi da HDPE da PP duka acid ne da alkali masu juriya a cikin zafin jiki, amma HDPE ya fi PP girma dangane da juriya na iskar shaka.Sabili da haka, lokacin adana kayan oxidizing, yakamata a zaɓi kwalabe na reagent HDPE;

Ƙananan nauyin kwayoyin halitta na aliphatic hydrocarbons, hydrocarbons aromatic hydrocarbons da chlorinated hydrocarbons na iya yin laushi da kumbura polypropylene.Don haka, ya kamata a yi amfani da kwalabe na reagent HDPE lokacin adana abubuwan kaushi kamar zoben benzene, n-hexane da chlorinated hydrocarbons.

3) Tauri da juriya mai tasiri

Polypropylene (PP) yana da kyakkyawan juriya ga gajiya, amma juriya mara kyau a yanayin zafi.Adadin juriya na kwalabe na HDPE yana da kyau fiye da na kwalabe na PP reagent, don haka kwalaben PP ba su dace da ajiyar yanayin zafi ba.

4)Transparency

PP ya fi dacewa fiye da HDPE kuma ya fi dacewa don lura da matsayi na kayan da aka adana a cikin kwalban.Duk da haka, musamman m PP kwalabe a kasuwa a halin yanzu suna da wani m wakili kara da abu, don haka kana bukatar ka mai da hankali a lokacin da zabar reagent kwalban sanya daga PP.

5) Hanyar haifuwa

Dangane da hanyoyin haifuwa, kawai bambanci tsakanin HDPE da PP shine cewa PP za a iya haifuwa ta babban zafin jiki da matsa lamba, amma HDPE ba zai iya ba.Dukansu biyu za a iya haifuwa ta EO da radiation (ana buƙatar PP mai juriya na iska, in ba haka ba zai zama rawaya) kuma masu kashe ƙwayoyin cuta.
