Izinto eziqhelekileyo zeplastiki ezisetyenziswayo kwiilabhoratri
Kukho izinto ezahlukeneyo zokulinga.Ukongeza kwizinto ezisetyenziswayo zeglasi, ezona zisetyenziswa ngokuqhelekileyo zizixhobo zeplastiki.Ngaba uyazi ukuba zeziphi izinto ezenziwe ngeplastiki ezisetyenziswa kubomi bemihla ngemihla?Ziziphi iimpawu?Indlela yokukhetha?Masiphendule nganye nganye nje ngasezantsi.
Izinto ezisetyenziswa kwiplastiki ezisetyenziswa elabhoratri ubukhulu becalaiingcebiso zepipette, iityhubhu ze-centrifuge,Iipleyiti zePCR, izitya zenkcubeko yeseli / iiplati / iibhotile, i-cryovials, njl. Uninzi lweengcebiso ze-pipette, iiplate ze-PCR, i-cryovials kunye nezinye izinto ezisetyenziswayo ezisetyenziswayo yiPP.Izinto eziphathekayo (ipolypropylene),izinto ezisetyenziswa kwinkcubeko yeselizenziwe ngokubanzi nge-PS (ipolystyrene), iiflaski zenkcubeko yeeseli zenziwe ngePC (polycarbonate) okanye iPETG (polyethylene terephthalate copolymer).
1. Ipolystyrene (PS)
Inokuhambisa ukukhanya okulungileyo kwaye ayinayo ityhefu, kunye nokuhanjiswa kokukhanya kwe-90%.Inokumelana kakuhle nemichiza kwizisombululo ezinamanzi, kodwa ukunganyangeki kakuhle kwizinyibilikisi.Ineenzuzo ezithile zeendleko xa kuthelekiswa nezinye iiplastiki.Ukucaca okuphezulu kunye nobunzima obuphezulu.
Iimveliso ze-PS zincinci kwiqondo lobushushu begumbi kwaye zithande ukuqhekeka okanye ukwaphuka xa ziwisiwe.Ubushushu bokusetyenziswa okuqhubekayo bumalunga ne-60 ° C, kwaye ubushushu bokusetyenziswa okuphezulu akufanele budlule kwi-80 ° C.Ayinakwenziwa inzala ngenxa yobushushu obuphezulu kunye noxinzelelo oluphezulu kwi-121°C.Unokukhetha ukuvala inzala ye-electron okanye ukuvalwa kweekhemikhali.
Iibhotile zenkcubeko yeseli ye-Shandong Labio, izitya zenkcubeko yeseli, iipleyiti zenkcubeko yeeseli, kunye neepayipi ze-serological zonke zenziwe nge-polystyrene (PS).
2. Polypropylene (PP)
Ubume bepolypropylene (PP) bufana ne-polyethylene (PE).I-resin ye-thermoplastic eyenziwe kwi-polymerization ye-propylene.Idla ngokuba yi-translucent colorless solid, ayinavumba kwaye ayinayo ityhefu.Inzuzo yayo ephambili kukuba ingasetyenziswa kumaqondo aphezulu kunye noxinzelelo lwe-121 ° C.Ncinza inzala.
I-Polypropylene (PP) ineempawu ezintle zomatshini kunye nokuchasana kweekhemikhali.Inokumelana nokugqwala kweeasidi, iialkali, ulwelo lwetyuwa kunye nezinyibilikisi ezahlukeneyo zendalo ezingaphantsi kwama-80°C.Inokuqina okungcono, amandla kunye nokumelana nokushisa kune-polyethylene (PE).;Ngokumalunga nokumelana nokushisa, i-PP nayo iphezulu kune-PE.Ke ngoko, xa ufuna ukuhanjiswa kokukhanya okanye ukubonwa lula, okanye ukumelana noxinzelelo oluphezulu okanye izinto ezisetyenziswayo kwiqondo lobushushu, ungakhetha izinto ezityiwayo zePP.
3. Polycarbonate (PC)
Inokuqina okuhle kunye nokuqina, ayiqhekeki ngokulula, kwaye inokuxhathisa ubushushu kunye nokumelana nemitha.Ihlangabezana neemfuno zobushushu obuphezulu kunye noxinzelelo oluphezulu lwesterilization kunye nokusetyenzwa kwemitha ephezulu kwi-biomedical field.I-Polycarbonate (PC) inokubonwa rhoqo kwezinye izinto ezisetyenziswayo, ezifanaiibhokisi zokukhenkcezakwayeiiflaski ze-erlenmeyer.
4. Polyethylene (PE)
Uhlobo lwe-thermoplastic resin, olungenavumba, olungenatyhefu, luvakalelwa njenge-wax, lunokumelana nokushisa okuphantsi kakhulu (iqondo lokushisa eliphantsi kakhulu linokufikelela ku -100~-70 ° C), kwaye lithambile ngokulula kumaqondo aphezulu.Inozinzo oluhle lweekhemikhali kuba iimolekyuli zepolymer zidityaniswe ngebhondi ye-carbon-carbon enye kwaye inokumelana nokukhukuliseka kwe-acids ezininzi kunye ne-alkalis (engenakuchasana ne-acids eneempawu ze-oxidizing).
Isishwankathelo, i-polypropylene (PP) kunye ne-polyethylene (PE) ziintlobo eziqhelekileyo zeplastiki kwiibhubhoratri.Xa ukhetha izinto ezisetyenziswayo, unokukhetha ezi zimbini ukuba akukho zidingo zikhethekileyo.Ukuba kukho iimfuno zokumelana nokushisa okuphezulu kunye nokushisa okuphezulu kunye noxinzelelo oluphezulu, unokukhetha izinto ezisetyenziswayo ezenziwe nge-polypropylene (PP);ukuba uneemfuno zokusebenza kweqondo lokushisa eliphantsi, ungakhetha i-polyethylene (PE);kunye nezinto ezisetyenziswa kwinkcubeko yeeseli Uninzi lwazo zenziwe nge-polystyrene (PS).
