Hauv kev lag luam plastics niaj hnub no, cov yas granulators, nrog rau lawv cov txiaj ntsig thev naus laus zis thiab kev ua tau zoo, tau dhau los ua qhov tseem ceeb txuas txuas cov khoom siv pov tseg yas siv thiab rov ua cov saw hlau. Lawv cov txiaj ntsig tsis yog tsuas yog cuam tshuam los ntawm kev ua tiav hauv ib qho - cov txheej txheem theem, tab sis kuj tseem nyob hauv kev txhim kho cov txiaj ntsig ntawm ib puag ncig, cov txiaj ntsig kev lag luam, thiab kev hloov pauv hauv kev lag luam, muab kev txhawb nqa zoo rau kev txhim kho kev lag luam plastics.
Ua ntej, cov txiaj ntsig tseem ceeb ntawm kev rov ua dua tshiab. Yas granulators tuaj yeem hloov cov khoom sib xyaw thiab pov tseg cov khoom yas (xws li ntim cov yeeb yaj kiab, lub raj mis flakes, thiab cov khoom seem hauv kev lag luam) rau hauv cov txheej txheem rov siv tau, tso cai rau cov khoom pov tseg uas yuav tsum tau muab pov tseg los yog incinerated kom rov- mus rau hauv lub voj voog ntau lawm. Cov txheej txheem "pov tseg-rau- khoom muaj nqis" no txo qis kev vam khom rau roj av-raws li cov yas yas, txo cov peev txheej rho tawm thiab cov pa roj carbon emissions, thiab ncaj qha rau kev ua tiav ntawm "dual carbon" cov hom phiaj. Nyob rau tib lub sijhawm, cov khoom siv lub cev ntawm cov granules rov ua dua yog nyob ze rau cov ntaub ntawv nkauj xwb, thiab lawv tuaj yeem siv dav hauv kev ntim khoom, cov khoom siv hauv tsev, cov khoom siv tsheb, thiab lwm yam kev lag luam, ua tiav siab - siv cov khoom pov tseg.
Thib ob, qhov zoo ntawm kev lag luam tus nqi zoo. Piv nrog rau kev tsim cov yas yas, siv cov pellets rov ua dua tuaj yeem txo cov nqi ntawm cov khoom siv raw khoom los ntawm 30% -60%, muab qhov txiaj ntsig ntev - cov nqi zoo, tshwj xeeb tshaj yog rau cov tuam txhab loj - cov khoom lag luam yas. Lub peev xwm ntau lawm ntawm cov yas pelletizers ntxiv txo cov nqi ua haujlwm, thaum lub ntsej muag tswj qhov kev tswj xyuas meej ntawm lub zog thiab cov khoom siv kom tsis txhob muaj cov khoom siv raw khoom pov tseg thiab lub zog redundancy, txhim kho tag nrho cov tswv yim-tso tawm piv.
Tsis tas li ntawd, lawv muab cov txheej txheem ua tau zoo thiab hloov tau yooj yim. Niaj hnub nimno yas pelletizers, los ntawm kev tsim qauv (xws li hloov tau screws thiab multi-theem temperature control systems), yog sib xws nrog ntau yam ntaub ntawv xws li PE, PP, PVC, thiab PET, nrog rau cov khoom siv pov tseg sib txawv uas xav tau nrog rau cov yeeb yaj kiab, cov nplooj ntawv nruj, thiab cov ntaub ntawv foamed. Txawm hais tias nws yog siab -purity recycling ntawm ib qho khoom siv lossis homogenization ntawm cov khoom sib xyaw, cov khoom siv tuaj yeem ua tiav cov txiaj ntsig ruaj khov los ntawm kev hloov pauv, ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev ua haujlwm hauv qab.
Tsis tas li ntawd, lawv muab ob qho kev lees paub ntawm kev tiv thaiv ib puag ncig thiab zoo. Cov cuab yeej yog nruab nrog lub tshuab nqus tsev pa thiab impurity pom cov cuab yeej, uas zoo tshem tawm cov pa phem tsis zoo thiab cov khoom impurities los ntawm cov yaj, ua kom huv si thiab kev nyab xeeb ntawm cov khoom siv rov ua dua tshiab. Precise temperature control technology tiv thaiv thermal degradation ntawm cov khoom, kom ntseeg tau tias kev ncaj ncees ntawm granules 'molecular qauv thiab ua rau lawv cov kev ua tau zoo indistinguishable los ntawm cov ntaub ntawv nkauj xwb.
Hauv cov ntsiab lus, cov yas granulator, nrog cov peev txheej rov ua dua tshiab ntawm nws cov tub ntxhais, koom ua ke ntau yam zoo xws li kev txo nqi thiab kev txhim kho kev ua haujlwm, hloov tau yooj yim, thiab kev ruaj ntseg zoo. Nws tsis yog tsuas yog ib qho tseem ceeb ntawm cov cuab yeej siv rau kev tswj cov pa phem hauv yas, tab sis kuj yog lub cav tseem ceeb rau kev tsav tsheb kev lag luam mus rau ntsuab thiab kev hloov kho kom zoo.
