Ukudla kwelebhu kuza ngezinhlobo ezahlukahlukene, futhi akukho nto eyodwa engahlangabezana nazo zonke izidingo zokuhlola. Ngakho-ke, uyazi ukuthi yiziphi izinto ezisetshenziswayo ezisetshenziswa ngokuvamile ezidlalweni zepulasitiki? Futhi yini umehluko ezingxenyeni zabo zomzimba nezamakhemikhali? Manje sizophendula le mibuzo ngamunye ngamunye ngezansi.

I-PP (polypropylene)

I-Polypropylene, ifinyezwe njenge-PP, i-polymer yakhiwa nge-polymerization yesengezo ye-propylene. Imvamisa i-translucent, iqinile eqinile, engenamkhuba, futhi engeyona ubuthi. Inokuqina okuhle kwezinga lokushisa futhi ingahle ibe nokubhubhana kwamazinga okushisa aphezulu nasengcindezini engu-121 ° C. Kodwa-ke, iba brittle emazingeni okushisa aphansi (ngaphansi kwe-4 ° C) futhi ithambekele ekuqhekekeni noma ukuqhekeka lapho kwehla kusuka ekuphakameni.

I-Polypropylene (PP) ibonisa izakhiwo ezinhle kakhulu zemishini kanye nokumelana kwamakhemikhali. Ingamelana ne-Corlosion kusuka kuma-acid, izisekelo, izixazululo kasawoti, kanye nama-sol ahlukahlukene we-organic emazingeni okushisa angaphansi kwama-80 ° C. Uma kuqhathaniswa ne-polyethylene (PE), i-PP inikeza ukuqina okungcono, amandla, nokumelana nokushisa. Ngakho-ke, lapho okunciphile kudinga ukudluliswa okukhanyayo noma ukubonwa okulula, kanye namandla aphezulu acindezelayo noma ukumelana nokushisa kwe-PP, izinto ze-PP zingakhethwa.

Okudliwayo okufana namashubhu we-centrifuge, amashubhu e-PCR 96-kahle, amabhodlela we-reagent, amashubhu wokugcina, namathiphu we-pipette anezenziwe nge-polypropylene njengezinto eziluhlaza.

I-PS (Polystyrene)

I-Polystyrere (PS), eyenziwe nge-redical polymerization yama-Styrene Monomers, i-thermoplastic engenamibala futhi esobala enokudluliselwa okukhanyayo okufika kuma-90%. I-PS ikhombisa ukuqina okuhle, ukungabi nobuthi, kanye nokuqina okubucayi, futhi inokuphikiswa okuhle kwamakhemikhali kwizisolo ezinamanzi kodwa ukumelana kabi nama-solvents. Imikhiqizo ye-PS ingenamikhawulo ekushiseni kwegumbi futhi ithambekele ekuqhekekeni noma ekuqhekekeni lapho kwehla. Ukushisa okuphezulu okuphezulu akufanele kudlule ama-80 ° C, futhi akunakukwazi ukubulawa inzalo emazingeni okushisa aphezulu kanye nezingcindezi ezingama-121 ° C. Esikhundleni salokho, inzalo ye-elektroni noma inzalo yamakhemikhali ingakhethwa.

Amapuleti abhalwe ama-enzyme abhalwe, okudliwayo kwamaseli, futhi ama-perim Pipette anezenziwe nge-polystyrene (ps) njengento eluhlaza.

I-PE (polyethylene)

I-Polyethylene, idonswe njenge-PE, i-thermoplastic resin etholwe nge-polymerization of ethylene monomers. Kungamakha, kungeyona-anobuthi, futhi kunomuzwa we-waxy. I-PE ibukisa ukumelana okuphansi okuphansi okuphansi (ngokushisa okuncane okusebenzayo okusukela ku--100 kuya ku -70 ° C). Iba ithambile emazingeni okushisa aphezulu futhi i-opaque.

Njengamanye ama-polyolof, i-polyethylene iyinto esetshenziswa ngamakhemikhali ngamakhemikhali ngokuqina okuhle kwamakhemikhali. Ngenxa yamabhodlela angashadile e-carbon-carbon ngaphakathi kwama-molecule we-polymer, kungamelana nokuguguleka kwama-acid amaningi nezisekelo (ngaphandle kwama-acid ane-acetone, aciy, ukuxhumana okuhlala isikhathi eside nge-oxidants eqinile kungadala ukuthi ku-oxidize futhi kube yi-brittle.

Amabhodlela eReagent, ama-Pipette, amabhodlela okugeza, nokunye okuthengisiwe kwenziwa ngokwezinto ezibonakalayo ze-polyethylene (pe).

I-PC (polycarbonate)

I-Polycarbonate, eyaziwa nangokuthi i-PC Plastic, iyi-polymer enamaqembu e-carbonate ecaleni lawo molecular. Kubonisa ubunzima obuhle nokuqina, okwenza kube ukumelana nokuphuka. Ngokwengeziwe, imelana nokuvikelwa kokushisa kanye nokuphikiswa kwemisebe, ukubhekana nezidingo zokushisa okuphezulu, ukubulawa kwabantu okuphezulu kanye nokwelashwa kwemisebe yamandla aphezulu ensimini ye-biomedical.

I-Polycarbonate imelana nama-acid abuthakathaka, izisekelo ezibuthakathaka, namafutha angathathi hlangothi. Kodwa-ke, akumelani nokukhanya okukhanyayo kwe-ultraviolet kanye nezisekelo eziqinile.

Amabhokisi we-FreeZing, eminye imikhono yamatshe kazibuthe, kanye namaflasks e-erlenmeyer enziwe nge-polycarbonate (PC) impahla.

Lokhu okungenhla kuchaza izinto ezimbalwa ezivamile ezisetshenziselwa ukufeka kwelebhu. Ngokuvamile, lezi zinto zokwenziwa zingakhethwa ngaphandle kwezidingo ezikhethekile. Uma ukuhlolwa kunezidingo ezithile, umuntu angabheka ukukhetha izinto ezihlangabezana nezidingo noma ukuguqula izinto ezikhona ukufezekisa izakhiwo ozifunayo.
