Dab tsi yog txoj hauv kev rau kev rov ua cov khoom pov tseg yas?
Muaj peb txoj hauv kev rau kev rov ua dua tshiab: 1. Kev kho cua sov decomposition: Txoj kev no yog ua kom sov thiab decompose cov khib nyiab pov tseg rau hauv cov roj lossis roj, lossis siv los ua lub zog lossis rov siv cov tshuaj siv los cais lawv rau hauv cov khoom siv petrochemical. Cov txheej txheem ntawm thermal decomposition yog: cov polymer depolymerizes ntawm qhov kub thiab txias, thiab cov saw hlau molecular tawg thiab decompose rau hauv me me molecules thiab monomers. Cov txheej txheem thermal decomposition yog txawv, thiab cov khoom kawg yog txawv, uas tej zaum yuav yog nyob rau hauv daim ntawv ntawm ib tug monomer, ib tug tsawg molecular hnyav polymer, los yog ib tug sib tov ntawm ntau hydrocarbons. Kev xaiv ntawm oilification lossis gasification txheej txheem yuav tsum yog raws li qhov xav tau tiag tiag. Cov kev siv yog: melting tank hom (rau PE, PP, random PP, PS, PVC, thiab lwm yam), microwave hom (PE, PP, random PP, PS, PVC, thiab lwm yam), ntsia hlau hom (rau PE, PP. , PS, PMMA). Tube evaporator hom (rau PS, PMMA), ebullating txaj hom (rau PP, random PP, cross-linked PE, PMMA, PS, PVC, thiab lwm yam), catalytic decomposition hom (rau PE, PP, PS, PVC, thiab lwm yam. ). Qhov teeb meem tseem ceeb hauv thermally decomposing plastics yog cov yas muaj cov thermal conductivity tsis zoo, uas ua rau kev lag luam loj thermal decomposition thiab thermal cracking nyuaj ua. Ntxiv nrog rau thermal decomposition, muaj lwm txoj kev kho tshuaj, xws li thermal cracking, hydrolysis, alcoholysis, alkaline hydrolysis, thiab lwm yam, uas tuaj yeem rov qab tau ntau yam khoom siv tshuaj.
2. Melt recycling Txoj kev no yog los txheeb, tsoo, thiab ntxuav cov khib nyiab pov tseg, thiab tom qab ntawd yaj thiab muab cov yas rau hauv cov khoom yas. Rau cov khoom pov tseg thiab cov khoom pov tseg los ntawm cov chaw tsim khoom thiab cov khoom siv yas thiab cov chaw tsim khoom, cov qauv no tuaj yeem siv los tsim ntau yam khoom zoo dua. Nws yog ib qho teeb meem rau kev txheeb xyuas thiab ntxuav cov khib nyiab yas siv hauv zej zog, thiab tus nqi siab. Lawv feem ntau yog siv los ua cov khoom ntxhib thiab cov khoom qis. 3. Composite reuse: Txoj kev no yog txhawm rau rhuav tshem cov khoom pov tseg, xws li PS ua npuas dej, PU ua npuas ncauj, thiab lwm yam.
