Kev rov ua dua tshiab ntawm lub raj mis yas yog ib txoj hauv kev siv cov khoom siv rov ua dua tshiab rau cov peev txheej ntawm cov ntaub ntawv polymeric. Thaum lub sij hawm ua, qhov teeb meem ntawm kev pov tseg pov tseg yog daws, thiab cov ntaub ntawv tau txais uas tuaj yeem rov siv tau rau kev tsim khoom, txawm tias siv qee qhov kev txwv (kev siv tshuab, kev tu cev, kev cai lij choj, kev huv huv) cuam tshuam nrog kev rov siv cov polymers.
Vim qhov tseeb tias polyethylene terephthalate (PET) muaj cov khoom siv kho tshuab ruaj khov, kev ua cov fwj yas los ntawm nws yog qhov pov thawj tshaj plaws thiab tsim txoj hauv kev ntawm kev siv cov khoom siv polymeric theem nrab. Muaj ob hom kev rov ua dua tshiab - txhua yam thiab tshuaj. Raws li txoj cai, feem ntau, kev ua haujlwm ntawm PET lub raj mis yog ua los ntawm kev siv tshuab, txij li cov txheej txheem tshuaj ua rau muaj kev xav tau ntau ntxiv ntawm cov khoom siv raw, thiab kev siv cov catalysts kim yog tsim nyog. Nrog txoj kev siv tshuab, plasticization ntawm pov tseg tsis tas yuav tsum tau. PET fwj yog thawj zaug txheeb los ntawm lwm hom ntim khoom polymer(polyethylene, PVC) thiab cov khoom txawv teb chaws (plugs, khib nyiab). Lub raj mis tuaj yeem txheeb los ntawm xim thiab txawm tias hom polymer, nyob ntawm qhov yuav tsum tau ua rau cov khoom kawg.
Kev ua thawj zaug ntawm lub raj mis yas siv qhov chaw ntawm rab riam crusher, qhov twg, raws li cov txheej txheem thev naus laus zis, PET hais txog 0.5-10 hli yog tsim. Lub resulting polymer crumb yog ntxuav nrog ib tug tov ntawm caustic soda los yog dej, tom qab uas nws yog qhuav raws li ib tug tej yam technology ntawm ib tug humidity ntawm 0.02-0.05% thiab kub ntawm 130 ºС. Cov txheej txheem ziab yog qhov tseem ceeb heev, tsis ua raws li qhov yuav tsum tau ua rau cov av noo ua rau muaj kev cuam tshuam tsis zoo hauv qhov zoo ntawm cov khoom siv thib ob.
Tom qab ziab, cov khoom yog agglomerated, vim hais tias cov crumb tau los ntawm cov theem dhau los ntawm cov thev naus laus zis yog sintered rau hauv cov pob me me. Nyob rau theem no, kev rov ua dua tshiab ntawm lub raj mis yas tuaj yeem ua tiav, txij li cov agglomerate tuaj yeem siv los ua cov khoom siv raw. Txhawm rau nruab nrab cov yam ntxwv ntawm lub cev ntawm recyclables, lawv tsim granulation. Raws li qhov tshwm sim, cov txheej txheem PET ua tiav dhau los ua qhov ntom ntom, thiab cov khoom siv tau yooj yim dua rau yav tom ntej thiab tau txais cov khoom tsim nyog ntawm cov cuab yeej txheem.
Qhov tseem ceeb ntawm kev siv cov khoom siv raw ntawm PET pov tseg yog tsim cov yeeb yaj kiab, fibers thiab lub raj mis. Raws li txoj cai, coj mus rau hauv tus account lub tshuab thiab rheological (cov ntaub ntawv ntws) cov khoom ntawm PET cov ntaub ntawv rov ua dua tshiab, nws yog siv rau kev tsim cov ntim rau ntau yam tshuaj. ATPET recycled tsis siv los ntim zaub mov. Recycled polyethylene terephthalate fiber ntau yog ua tiav rau hauv cov ntaub pua plag thiab khaub ncaws lossis textiles. Cov khoom siv rov ua dua tshiab kuj tseem siv rau kev tsim cov geotextiles, hluavtaws hluavtaws, cov khoom siv suab nrov, cov khoom nqus thiab lim, cov khoom siv hluav taws xob, fittings (los ntawm casting), automotive qhov chaw.

Cov khoom qiv nyiaj yog qhov tseem ceeb rau cov neeg qiv nyiaj niaj hnub no. Rau ntau tus, qhov no tsuas yog lub sijhawm los ua ib qho kev yuav khoom loj lossis dhau los ua tus tswv ntawm lawv tus kheej cov khoom. Tab sis tsis yog ib txwm lub txhab nyiaj pom zoo cov nyiaj yuav tsum tau. Feem ntau yog vim li cas yog keeb kwm credit tsis zoo. Qhov teeb meem tshwj xeeb rau cov neeg muaj peev xwm ntawm cov tuam txhab nyiaj txiag uas tau raug tsis lees paub daim ntawv thov kev pom zoo yog qhov twg thiab ntev npaum li cas cov ntaub ntawv no raug khaws cia
