Yakajairika plastiki inodyiwa zvinhu mumarabhoritari
Kune zvakasiyana-siyana zvekuedzwa zvinodyiwa.Mukuwedzera kune zvigadzirwa zvegirazi, iyo inonyanya kushandiswa ndeyepurasitiki inoshandiswa.Saka unoziva here kuti zvinhu zvipi zvinoshandiswa nepurasitiki zvinoshandiswa muhupenyu hwezuva nezuva zvinogadzirwa?Ndeapi maitiro?Nzira yekusarudza?Ngatipindurei mumwe nemumwe sepazasi.
Zvishandiso zvepurasitiki zvinoshandiswa murabhoritari ndizvo zvakanyanyapipette mazano, centrifuge tubes,PCR mahwendefa, sero tsika ndiro / ndiro / mabhodhoro, cryovials, etc. Mazhinji epipette mazano, PCR plates, cryovials nezvimwe zvinoshandiswa zvinoshandiswa ndezvePP.zvinhu (polypropylene),sero tsika consumablesanowanzo kugadzirwa nePS (polystyrene), sero tsika flasks anogadzirwa nePC (polycarbonate) kana PETG (polyethylene terephthalate copolymer).
1. Polystyrene (PS)
Iine mwenje wakanaka wekufambisa uye haina chepfu, ine mwenje we90%.Iyo ine yakanaka makemikari kuramba kune aqueous mhinduro, asi kushomeka kuramba kune zvinonyungudutsa.Iyo ine zvimwe zvakanakira mutengo zvichienzaniswa nemamwe mapurasitiki.High pachena uye yakakwirira kuoma.
Zvigadzirwa zve PS zvine brittle pakudziya kwekamuri uye zvinowanzo putika kana kutsemuka kana zvadonha.Kuenderera mberi kwekushandisa tembiricha inenge 60°C, uye tembiricha yekushandisa haifanire kudarika 80°C.Haikwanise kucheneswa nekupisa kwepamusoro uye kudzvanywa kwepamusoro pa121°C.Iwe unogona kusarudza electron beam sterilization kana makemikari sterilization.
Shandong Labio's cell tsika mabhodhoro, sero tsika ndiro, sero tsika mahwendefa, uye serological pipettes ese akagadzirwa ne polystyrene (PS).
2. Polypropylene (PP)
Chimiro chepolypropylene (PP) chakafanana ne polyethylene (PE).Iyo thermoplastic resin yakagadzirwa kubva ku polymerization yepropylene.Inowanzoita translucent colorless yakasimba, isina kunhuwa uye isina chepfu.Kubatsira kwayo kukuru ndeyekuti inogona kushandiswa pakupisa kwakanyanya uye kumanikidza kwe121 ° C.Sterilize.
Polypropylene (PP) ine yakanaka mechanical zvivakwa uye makemikari kuramba.Inogona kumira nekuora kweasidhi, alkalis, zvinwiwa zvine munyu uye zvakasiyana-siyana zvinonyungudutsa zveorganic zviri pasi pe80°C.Iine kuoma kuri nani, simba uye kupisa kwekudzivirira kupfuura polyethylene (PE).;Panyaya yekudzivirira kwekushisa, PP zvakare yakakwirira kupfuura PE.Naizvozvo, kana iwe uchida kutapurirana mwenje kana kutarisisa kuri nyore, kana yakakwira kudzvanya kuramba kana tembiricha zvinobatika, unogona kusarudza PP zvinodyiwa.
3. Polycarbonate (PC)
Iine kusimba kwakanaka uye kusimba, haisi nyore kuputsika, uye ine zvese zvinodzivirira kupisa uye kuramba nemwaranzi.Inosangana nezvinodiwa zvekupisa-kupisa uye high-pressure sterilization uye high-energy radiation processing mumunda webiomedical.Polycarbonate (PC) inogona kazhinji kuoneka mune zvimwe zvinoshandiswa, sengemabhokisi echandouyeerlenmeyer flasks.
4. Polyethylene (PE)
Rudzi rwe thermoplastic resin, isinganhuhwi, isina muchetura, inonzwa kunge wakisi, ine yakanyanya kudzika tembiricha kuramba (yakadzika tembiricha yekushanda inogona kusvika -100~-70 ° C), uye inopfava zviri nyore pakupisa kwakanyanya.Iine kugadzikana kwakanaka kwemakemikari nekuti mamorekuru epolymer akabatana kuburikidza nekabhoni-kabhoni imwe mabhondi uye anogona kuramba kukukurwa kwemaasidhi mazhinji nemaalkali (asingamirire kune acid ane oxidizing properties).
Muchidimbu, polypropylene (PP) uye polyethylene (PE) ndiwo marudzi akajairika emapurasitiki mumarabhoritari.Pakusarudza zvinodyiwa, unogona kazhinji kusarudza izvi zviviri kana pasina zvakakosha zvinodiwa.Kana pane zvinodiwa zvekudzivirira kwekushisa kwepamusoro uye kupisa kwepamusoro uye high pressure sterilization, unogona kusarudza zvinoshandiswa zvakagadzirwa ne polypropylene (PP);kana iwe uine zvinodiwa pakuita kwakadzika tembiricha, unogona kusarudza polyethylene (PE);uye nokuda kwesero tsika zvinodyiwa Zvizhinji zvacho zvakagadzirwa ne polystyrene (PS).
