Izikhongozeli zeplastiki ezisetyenziswa ngokuqhelekileyo elabhoratri zibandakanya iibhotile ze-reagent, iityhubhu zovavanyo, iintloko zokufunxa, iindiza, iikomityi zokulinganisa, iisilinda zokulinganisa, iisirinji ezilahlwayo kunye neepayipi.Iimveliso zePlastiki zineempawu zokwenza lula, ukusetyenzwa kakuhle, ukusebenza kakuhle kococeko kunye nexabiso eliphantsi.Zitshintsha ngokuthe ngcembe iimveliso zeglasi kwaye zisetyenziswa kakhulu kuphando lwezenzululwazi, ukufundisa kunye nezinye iinkalo.
Iintlobo zeemveliso zeplastiki ezisetyenziswa rhoqo kwiilabhoratri
Inxalenye ephambili yeeplastiki yi-resin, kunye ne-plasticizers, iifayili, i-lubricant, i-colorants kunye nezinye izongezo njengamacandelo ancedisayo.Iimveliso zeplastiki ezinezakhiwo ezahlukeneyo zineempawu ezahlukeneyo.Iimveliso zePlastiki ezingakhathaleli kwizinto zebhayoloji, ezifana ne-polyethylene, i-polypropylene, i-polymethylpentene, i-polycarbonate, i-polystyrene kunye ne-polytetrafluoroethylene, zikhethwa ngokubanzi kwiilabhoratri.Ii-reagents zemichiza zinokuchaphazela amandla oomatshini, ukuqina, ukugqiba umphezulu, umbala kunye nobukhulu beemveliso zeplastiki.Ngoko ke, ukusebenza kwemveliso nganye yeplastiki kufuneka kuqondwe ngokupheleleyo xa ukhetha iimveliso zeplastiki.

1. Polyethylene (PE)
Ukuzinza kweekhemikhali kulungile, kodwa kuya kuba yi-oxidized kwaye ibe brittle xa idibana ne-oxidant;Ayinyibiliki kwi-solvent kwiqondo lobushushu begumbi, kodwa iya kuthamba okanye yande xa kukho isinyibilikisi esidlekayo;Ipropathi yococeko yeyona ilungileyo.Ngokomzekelo, amanzi adibeneyo asetyenziselwa inkcubeko yenkcubeko ahlala egcinwe kwiibhotile ze-polyethylene.
2. Polypropylene (PP)
Ifana ne-PE kwisakhiwo kunye nokusebenza kococeko, imhlophe kwaye ayinancasa, inoxinano oluncinci, kwaye yeyona ilula phakathi kweeplastiki.Iyakwazi ukumelana noxinzelelo oluphezulu, inyibilika kwiqondo lobushushu begumbi, ayisebenzi kumajelo osasazo amaninzi, kodwa ibuthathaka kakhulu kwi-oxidants eyomeleleyo kune-PE, ayixhathisi kubushushu obuphantsi, kwaye ibuthathaka ku-0 ℃.
3. Polymethylpentene (PMP)
Ukungafihli, ukumelana nobushushu obuphezulu (150 ℃, 175 ℃ ixesha elifutshane);Ukuxhatshazwa kweekhemikhali kusondele kwi-PP, ethambileyo ngokulula ngama-solvents e-chlorinated kunye ne-hydrocarbons, kwaye i-oxidized ngokulula kune-PP;Ubunzima obuphezulu, ukuqina okuphezulu kunye nobuthathaka kwiqondo lokushisa.
4. Polycarbonate (PC)
Ingafihli, iqinile, ayinatyhefu, uxinzelelo oluphezulu kunye nokumelana ne-oyile.Inokusabela ngotywala be-alkali kunye ne-asidi yesulfuric egxininisiweyo, i-hydrolyze kwaye inyibilike kwiintlobo ezahlukeneyo ze-solvents eziphilayo emva kokufudumeza.Ingasetyenziswa njengetyhubhu ye-centrifuge yokucolisa yonke inkqubo kwibhokisi ye-ultraviolet sterilization.
5. Ipolystyrene (PS)
Ayinambala, ayinancasa, ayinatyhefu, ayibonakali, kwaye iyindalo.Ukumelana ne-solvent ebuthathaka, amandla aphantsi oomatshini, i-brittle, kulula ukuqhekeka, ukumelana nobushushu, ukutsha.Iqhele ukusetyenziselwa ukwenza izinto zonyango ezilahlwayo.
6. Polytetrafluoroethylene (PTEE)
Imhlophe, i-opaque, i-wear-resistant, esetyenziswa ngokuqhelekileyo ukwenza iiplagi ezahlukeneyo.
7. Polyethylene terephthalate G copolymer (PETG)
Ingafihli, iqinile, ayinamoya, kwaye ayinayo ityhefu yebhaktheriya, isetyenziswa ngokubanzi kwinkcubeko yeeseli, njengokwenza iibhotile zenkcubeko yeeseli;Iikhemikhali zerediyo zingasetyenziselwa ukubulala iintsholongwane, kodwa ukutshabalalisa iintsholongwane ezinoxinzelelo oluphezulu akunakusetyenziswa.
