Cov thawv yas uas siv ntau hauv chav kuaj muaj xws li reagent fwj, cov raj xa dej, lub taub hau nqus, straws, ntsuas khob, ntsuas lub tog raj kheej, cov koob txhaj tshuaj pov tseg thiab cov kav dej.Cov khoom yas muaj cov yam ntxwv ntawm kev sib sau yooj yim, kev ua haujlwm yooj yim, kev huv huv zoo thiab tus nqi qis.Lawv maj mam hloov cov khoom iav thiab tau siv dav hauv kev tshawb fawb, kev qhia thiab lwm yam.
Hom ntawm cov khoom yas feem ntau siv nyob rau hauv lub chaw soj nstuam
Cov khoom tseem ceeb ntawm cov yas yog cob, nrog cov yas yas, cov khoom ntim, cov roj nplaum, cov xim thiab lwm yam khoom siv ntxiv ua cov khoom siv.Cov khoom yas nrog cov qauv sib txawv muaj cov khoom sib txawv.Cov khoom yas uas tsis rhiab rau cov khoom siv roj ntsha, xws li polyethylene, polypropylene, polymethylpentene, polycarbonate, polystyrene thiab polytetrafluoroethylene, feem ntau yog xaiv rau cov chaw soj nstuam.Cov tshuaj reagents tuaj yeem cuam tshuam rau lub zog txhua yam, hardness, nto tiav, xim thiab loj ntawm cov khoom yas.Yog li ntawd, kev ua tau zoo ntawm txhua yam khoom yas yuav tsum tau nkag siab zoo thaum xaiv cov khoom yas.

1. Polyethylene (PE)
Kev ruaj ntseg tshuaj zoo, tab sis nws yuav oxidized thiab nkig thaum ntsib oxidant;Nws yog insoluble nyob rau hauv hnyav ntawm chav tsev kub, tab sis yuav ua mos los yog nthuav nyob rau hauv cov ntaub ntawv ntawm corrosive hnyav;Cov cuab yeej tu cev yog qhov zoo tshaj plaws.Piv txwv li, dej distilled siv rau kab lis kev cai nruab nrab yog feem ntau khaws cia rau hauv lub hwj polyethylene.
2. Polypropylene (PP)
Zoo ib yam li PE hauv cov qauv thiab kev ua haujlwm tu cev, nws yog xim dawb thiab tsis qab, nrog qhov ntom ntom me me, thiab yog lub teeb tshaj plaws ntawm cov yas.Nws yog resistant rau kev kub siab, soluble nyob rau hauv chav tsev kub, tsis ua hauj lwm nrog feem ntau cov xov xwm, tab sis yog rhiab heev rau cov oxidants muaj zog tshaj PE, tsis resistant rau kub kub, thiab yog rhiab heev ntawm 0 ℃.
3. Polymethylpentene (PMP)
Pob tshab, kub resistant (150 ℃, 175 ℃ rau ib lub sijhawm luv luv);Cov tshuaj tiv thaiv yog ze rau ntawm PP, uas yog yooj yim softened los ntawm chlorinated cov kuab tshuaj thiab hydrocarbons, thiab yog yooj yim oxidized dua PP;High hardness, siab brittleness thiab fragility ntawm chav tsev kub.
4. Polycarbonate (PC)
Pob tshab, tawv, tsis muaj tshuaj lom, siab siab thiab roj resistant.Nws tuaj yeem hnov mob nrog alkali cawv thiab concentrated sulfuric acid, hydrolyze thiab yaj nyob rau hauv ntau yam organic solvents tom qab rhuab.Nws tuaj yeem siv los ua lub raj centrifuge kom tsis muaj menyuam tag nrho cov txheej txheem hauv lub thawv ultraviolet sterilization.
5. Polystyrene (PS)
Tsis muaj xim, tsis qab, tsis muaj tshuaj lom, pob tshab, thiab ntuj.Cov kuab tshuaj tsis muaj zog, tsis muaj zog txhua yam, nkig, yooj yim tawg, kub resistant, flammable.Nws yog feem ntau siv los ua cov khoom siv kho mob pov tseg.
6. Polytetrafluoroethylene (PTEE)
Dawb, opaque, hnav-resistant, feem ntau siv los ua ntau yam ntsaws.
7. Polyethylene terephthalate G copolymer (PETG)
Pob tshab, tawv, airtight, thiab tsis muaj kab mob co toxins, nws yog dav siv hauv cell kab lis kev cai, xws li ua cell kab lis kev cai fwj;Cov tshuaj tua kab mob tuaj yeem siv rau kev tua kab mob, tab sis kev siv tshuaj tua kab mob siab tsis tuaj yeem siv.
