Ukuqhathaniswa kokusebenza kwe-PP kanye ne-HDPE, Izinto Ezimbili Ezisetshenziswa Kakhulu Ezisetshenziswa Ngokujwayelekile zamabhodlela e-Reagent

Ngokunwetshwa okuqhubekayo kobubanzi bokufaka isicelo sezinto ezahlukahlukene ze-polymer, amabhodlela epulasitiki e-reagent kancane kancane asetshenziswe kabanzi ekugcineni ama-reagents amakhemikhali.Phakathi kwezinto zokusetshenziswa zokukhiqiza amabhodlela epulasitiki e-reagent, i-polypropylene (PP) kanye ne-high-density polyethylene (HDPE) yizinto ezimbili ezivame ukusetshenziswa.Ngakho-ke yimuphi umehluko ekusebenzeni phakathi kwalezi zinto ezimbili?

1)TumkhathiRukuphikisa

Izinga lokushisa le-embrittlement le-HDPE lingu-100°C kanti lelo le-PP lingu-0°C.Ngakho-ke, lapho imikhiqizo idinga isitoreji sezinga lokushisa eliphansi, amabhodlela e-reagent enziwe nge-HDPE akhethwa kakhulu, njengamabhafa angu-2-8°C asetshenziselwa ukugcina ama-reagents okuxilonga.Amabhodlela e-reagent ye-Buffer kanye -20°C enzyme;

2) ChemicalRukuphikisa

Amabhodlela e-reagent enziwe nge-HDPE ne-PP womabili ane-asidi ne-alkali amelana nezinga lokushisa legumbi, kodwa i-HDPE iphakeme kune-PP ngokokumelana ne-oxidation.Ngakho-ke, lapho ugcina izinto ze-oxidizing, amabhodlela e-HDPE reagent kufanele akhethwe;

Isisindo esiphansi sama-aliphatic hydrocarbons, ama-hydrocarbon anephunga elimnandi nama-hydrocarbon ane-chlorinated angathambisa futhi avuvuke i-polypropylene.Ngakho-ke, amabhodlela e-HDPE reagent kufanele asetshenziswe lapho kugcinwa izincibilikizi eziphilayo njengamaringi e-benzene, i-n-hexane nama-hydrocarbon ane-chlorine.

3) Ukuqina kanye nokumelana nomthelela

I-Polypropylene (PP) inokumelana nokukhathala okuhle kakhulu, kodwa ukumelana nomthelela omubi emazingeni okushisa aphansi.Ukumelana nokwehla kwamabhodlela e-HDPE reagent kungcono kakhulu kunamabhodlela e-PP reagent, ngakho-ke amabhodlela e-PP awafaneleki ukugcina izinga lokushisa eliphansi.

4)Tukungafihli

I-PP isobala kakhulu kune-HDPE futhi ivumela kakhulu ukubheka isimo sezinto ezigcinwe ebhodleleni.Kodwa-ke, amabhodlela e-PP asobala kakhulu emakethe njengamanje ane-ejenti esobala engezwe kundaba, ngakho-ke udinga ukunaka lapho ukhetha ibhodlela le-reagent elenziwe nge-PP.

5) Indlela yokuvala inzalo

Mayelana nezindlela zokuvala inzalo, umehluko kuphela phakathi kwe-HDPE ne-PP ukuthi i-PP ingafakwa inzalo ngokushisa okuphezulu nokucindezela okuphezulu, kodwa i-HDPE ayikwazi.Kokubili kungenziwa inzalo nge-EO kanye nemisebe (iyadingeka i-PP engavimbeli imisebe, ngaphandle kwalokho izophenduka ibe phuzi) futhi Izibulala-magciwane zibulala amagciwane.
