Dab tsi yog qhov kho qauv ntawm cov khib nyiab plastics? - Suzhou Polytime Tshuab Co., Ltd.

Hauv lub neej txhua hnub, cov khoom yas tuaj yeem pom yuav luag txhua qhov chaw. Nws muab rau peb ntau ntawm kev yooj yim, tab sis nws kuj coj ntau yam kuab paug dawb. Vim yog lawv lub teeb yuag, pov tseg plastics ntau zaus ya nrog cua hauv huab cua, uas muaj kuab paug, uas cuam tshuam rau qhov kev zoo nkauj ntawm lub nroog. Nyob rau tib lub sijhawm, vim yog cov qauv polymer ntawm cov plastics, qhov kev ua rau muaj kev ua rau txhua xyoo ntau dua li ib puas xyoo. Yog li ntawd, thaum ntim ntaub pua plag nkag mus rau ib puag ncig, nws yuav ua rau muaj teeb meem kev teeb meem ntev. Rov qab ua dua cov khib nyiab kom muaj peev xwm txo tau lub siab ntawm cov kev pab, txuag thaj av thiab tau txais qee cov txiaj ntsig kev lag luam. Yog li ntawd, lub ntiaj teb yog tas li kev tshawb nrhiav tas li thiab sim nrhiav kom pom kev daws teeb meem zoo dua kom pov tseg plastics.

Cov khoom siv ntawm plastics yog dab tsi?

Yas (tseem hu ua hluavtaws resin) yog hom molecular siab organic compound. Nws lub ntsiab tivthaiv yog cob, thiab ntau yam ntxiv ntxiv ntxiv kom tau raws li cov kev xav tau sib txawv. Ntawm lawv, Resins tau muab faib ua ob pawg: cov resins thiab hluavtaws resins. Nyob rau tib lub sijhawm, kev ua yeeb yam ntawm Resin txiav txim siab qhov kev ua tau zoo ntawm plastics, uas yog qhov tsim nyog tivthaiv. Ntxiv (tseem hu ua cov quav ntxiv) kuj tseem muaj qhov cuam tshuam tseem ceeb heev rau cov khoom tseem ceeb ntawm cov plastics. Nws tuaj yeem txhim kho txoj kev sib haum thiab kev ua tau zoo ntawm cov yas, txo tus nqi hauv cov txheej txheem ntau lawm thiab hloov cov kev pabcuam kev ua haujlwm ntawm plastics.

Nyob rau hauv chav tsev kub, yas tuaj yeem tswj hwm cov duab. Kom nws ua rau nws mus rau hauv qee qhov duab, nws yuav tsum nyob hauv qab qhov ntsuas kub thiab cov xwm txheej siab.

Cov kev kho mob ntawm cov khib nyiab plastics?

1. Cov tawv ntoo

Txoj kev ua pov thaiv cov ntawv pov tseg kom xa cov khib nyiab kom ntub dej rau cov chaw pov tseg. Hom no yog yooj yim thiab yooj yim thiab tseem feem ntau siv nyob rau hauv ntau lub teb chaws. Txawm li cas los xij, vim qhov loj ntim ntawm cov yas thiab tsawg npaum li cas ntawm cov khib nyiab uas tuaj yeem tso, nws tseem yuav ua rau khib nyiab av. Ntxiv mus, tom qab cov av khib nyiab, cov teeb meem phom sij nyob hauv cov khib nyiab yuav nkag rau hauv av, cuam tshuam rau cov av qauv, ua rau cov dej qias neeg theem nrab. Ntxiv mus, qhov av tsaws ntawm cov neeg rov qab muaj peev xwm yooj yim plastics tau ua rau cov pov tseg ntawm cov peev txheej, uas tsis yog txoj kev txhim kho kom ruaj khov los ntawm peb lub teb chaws.

2. Thermochemical Rov Qab Txuj Ci

Lub thermialchemical rov qab txoj kev tuaj yeem faib ua cov txheej txheem kev sib cais thiab cov pyrolysis qauv.

Kev ntsuas hluav taws xob txhais tau tias tias ntau npaum li cas ntawm cov cua sov tuaj yeem tau txais thiab cov haujlwm hauv av tuaj yeem txo los ntawm hlawv pov tseg plastics. Tus qauv muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab tus nqi qis. Txawm li cas los xij, hauv cov txheej txheem ntawm kev sib txuas, teeb meem roj yuav raug tsim tawm, ua rau muaj pa phem. Pyrolysis yog hais txog cov tsis muaj zog thermials cov tshuaj tiv thaiv ntawm cov organic cov khib nyiab los tsim cov roj ua ke, TAR, thiab Coke hauv qhov tsis muaj pa lossis oxygen. Cov txheej txheem pyrolysis muaj cov txheej txheem pyrxysis muaj cov txheej txheem sib xyaw, cov cuab yeej siv tau cov khoom muaj nqis, cov nqi ntau lawm, kev rov ua haujlwm siab, thiab tsawg daim ntawv thov ntau.

3. Kev rov ua haujlwm ib yam

Mechanical rov qab cov hau kev yog muab faib ua ob pawg: yooj yim dua tshiab thiab hloov kho tshiab. Cov txheej txheem rov qab yog qhov ntsuab, ua tau zoo, thiab siv dav. Nws cov txheej txheem yog kom tshem tawm impurities, crush, huv si, thiab xaus pov tseg kom qhuav, thiab thaum kawg yaj, granulate thiab ua kom lawv tau ua cov khoom lag luam tshiab.

Dab tsi yog cov ntawv thov ntawm cov yas ntoo tshuab yas hauv cov txheej txheem yas dua tshiab?
YAS siv lub tshuab siv hluav taws xob feem ntau yog siv rau cov tshuab ua haujlwm ntawm cov khoom pov tseg yas. Lub tshuab siv yas tshuab hluav taws xob yog lub npe dav dav ntawm cov tshuab rau cov khoom siv ua kom rov qab ua kom huv. Nws tsuas yog hais txog cov khib nyiab yas cov khoom siv thiab cov khoom siv granulation, suav nrog cov khoom siv pretreatic thiab cov khoom siv granulation.

Hauv kev ua dua tshiab, cov pov tseg plastics yog tshuaj ntsuam, cais, crushed, ntxuav, qhuav dej, thiab qhuav los ntawm cov khoom siv pretreates. Cov cuab yeej ua kom sib raug zoo yuav tsum raug xaiv raws li qhov txuas, cov ntaub ntawv raw yas, thiab tso zis. Tom qab ntawd, cov kab yas tawg yog yas, extruded, kos, thiab granulator, thiab thaum kawg, lub hom phiaj ntawm kev rov ua dua tshiab tau ua tiav.

Muaj ntau txoj kev kho mob rau cov khib nyiab plastics, ntawm cov kev kho tshuab rov qab yog ntsuab, muaj cov nyhuv zoo, thiab yog siv dav. Tsoos cov khoom siv roj hmab yas yuav tsum tau zuaj yas, uas nce cov nqi rov qab, txo qhov rov ua dua tshiab, thiab ua rau cov neeg ua haujlwm ua haujlwm tsis zoo. Kev txhim kho kev txhim kho ntawm cov tshuab siv yas los ntawm kev txhim kho siab thiab tshiab yog cov thawj coj txhim kho ntev rau yav tom ntej. Suzhou Polytime Tshuab Co., Ltd. yog cov lag luam siab ua lag luam nrog kev tshawb fawb thiab thev naus laus zis raws li cov coj thiab lub neej zoo. Tam sim no, nws tau tsim mus rau ib qho ntawm cov khoom siv ntau ntxiv hauv paus hauv paus. Yog tias koj tau koom nrog kev khib nyiab yas siv, koj tuaj yeem xav txog peb cov khoom lag luam siab.
