Cov khib nyiab yas tuaj nyob rau hauv ntau hom, xws li los ntawm cov thawv nruj thiab cov ntaub ntawv loj mus rau lub teeb yuag ntim cov yeeb yaj kiab thiab cov hnab woven, nrog rau cov kev lag luam tsis yooj yim thiab tom qab- cov neeg siv khoom sib xyaw. Txhua yam khoom siv sib raug rau txoj hauv kev rov ua dua tshiab thiab cov khoom siv sib xyaw ua ke vim qhov sib txawv ntawm lub cev (xws li thickness, ntom, thiab cov duab) thiab qib sib kis. Kev xaiv cov cuab yeej tsim nyog hauv paus yuav tsum sib piv lub tshuab lub peev xwm rau cov khoom siv raw cov yam ntxwv. Qhov no yog lub hauv paus rau kev ua kom tau txais txiaj ntsig zoo dua qub, ua kom cov khoom tsim tau zoo, thiab tswj cov nqi ua haujlwm ntev -.
Pib nrog cov khoom siv raw, phim cov khoom siv tseem ceeb
Cov ntaub ntawv pov tseg sib txawv muaj cov kev sib tw sib txawv hauv cov txheej txheem rov ua dua tshiab, ua rau muaj qhov sib txawv loj heev rau cov khoom siv tseem ceeb.
1. Rigid Plastics (piv txwv li, HDPE / PP fwj, txhaj tshuaj -moulded qhov chaw, kav dej): Cov ntaub ntawv no feem ntau yog loj thiab tawv. Thawj kauj ruam rov ua dua tshiab yuav tsum muaj siab - zog, siab - torqueshredderstxhawm rau rhuav lawv mus rau hauv cov flakes sib xws. Kev ntxuav cov khoom siv shredded yog qhov ncaj ncaj, feem ntau cuam tshuam nrog kev tshem tawm cov ntawv nplaum thiab stains. Thaum lub sij hawm extrusion pelletizing theem, thaum cov yas tawv muaj qhov zoo txaus thiab yog li tso qhov kev xav tau tsawg kawg ntawm cov khoom siv pub mis, lub siab - qhov kev pom tseeb yog qhov tseem ceeb los tshem tawm cov khoom seem hlau lossis cov xuab zeb, kom ntseeg tau qhov zoo ntawm cov khoom siv rov ua dua tshiab.
2. Soft Films thiab Woven Bags (piv txwv li, LDPE / LLDPE zaj duab xis ua liaj ua teb, PP woven hnab, khw hnab): Vim lawv lub teeb yuag, thinness, thiab siab bulkiness, cov ntaub ntawv zaj duab xis sawv cev rau ib qho nyuaj tshaj plaws hauv kev rov ua dua tshiab.
- Kev pub mis yog qhov nyuaj heev: Kev noj cov pa nqus tau yooj yim ua rau kev hla thiab txhaws. Yog li ntawd, ib tug yuam kev pub khoom noj los yog compaction / agglomeration khoom yuav tsum tau muab ntsia rau saum toj kawg nkaus rau compress xoob zaj duab xis rau hauv tuab blocks los yog pellets kom ruaj khov, uniform pub rau hauv.tusextruder.
- Kev tu thiab ziab kom qhuav: Kev tu zaj duab xis xav tau kev sib txhuam kom muaj zog (xws li, kev sib txhuam ntxhua) kom tshem tawm cov kab mob thiab cov khoom seem. Tom qab- ntxuav lub cev qhuav dej yog qhov tseem ceeb, feem ntau yuav tsum tau siab -ceev centrifugallub cev qhuav dejkom txo cov dej noo tsawg kawg nkaus - txwv tsis pub cov dej seem yuav cuam tshuam cov pellet zoo.
- Lim thiab degassing: Cov yeeb yaj kiab (tshwj xeeb yog cov yeeb yaj kiab luam tawm) muaj cov impurities thiab volatiles siab. Qhov no yuav tsum muaj qhov loj - thaj chaw pom cov tshuab (piv txwv li, ob npaug -piston screen changers) kom txo qhov kev hloov pauv zaus, nrog rau siab -cov tshuab nqus tsev degassing kom tshem tawm cov roj thaum lub sij hawm yaj. Qhov no ua kom cov pellets ntom ntom tsis muaj voids.
3. Engineering Plastics thiab Mixed Waste (piv txwv li, ABS, PA, PC, lossis complex multilayer composites):
- Rau siab -kev ua tau zoo engineering yas recycling, khaws cia cov khoom qub yog qhov tseem ceeb. Qhov no feem ntau xav tau kev ua kom zoo dua qub, ua kom meej dua kom tsis txhob muaj kev kub ntxhov ntau dhau -kub degradation. Cov khoom siv yuav xav tau kev tswj qhov kub thiab txias thiab ntau-theem degassing peev xwm.
- Thaum ua cov khoom pov tseg sib xyaw lossis cov khoom siv uas muaj qhov nyuaj -kom- cais cov impurities, pem hauv ntej- cov khoom siv kawg (xws li ze rau -infrared spectroscopy sorters lossis electrostatic separators) yog qhov tseem ceeb. Cov tshuab no tuaj yeem cais cov ntaub ntawv yas sib txawv los yog tshem tawm cov khoom tsis huv siab - ua ntej shredding thiab ntxuav, nteg lub hauv paus rau kev tsim cov khoom siv siab - purity recycled.
- Rau cov ntaub ntawv nyuaj rau kev ua haujlwm los ntawm kev rov ua dua lub cev, xws li kev ntim khoom sib xyaw, kev siv tshuaj lom neeg (piv txwv li, depolymerization, pyrolysis) yuav raug txiav txim siab los hloov lawv mus rau hauv cov khoom siv tshuaj.
Ntau-Txoj kev xav txog kev xaiv khoom siv
Tom qab txiav txim siab txog hom khoom siv raw, cov hauv qab no yuav tsum tau soj ntsuam tag nrho thaum xaiv cov cuab yeej tshwj xeeb:
- Peev xwm thiab Scale Matching: Cov cuab yeej ua kom muaj peev xwm yuav tsum ua raws li qhov xav tau ntawm cov khoom siv raw khoom. Lub peev xwm tsis txaus txwv txoj kev loj hlob, thaum muaj peev xwm ntau dhau ua rau cov khoom siv tsis muaj zog thiab cov khoom siv hluav taws xob pov tseg. Nyob rau tib lub sijhawm, xyuas kom muaj qhov sib npaug ntawm tag nrho cov kab, kev sib koom tes ntawm kev sib tsoo, ntxuav, pelletizing, thiab lwm theem kom tsis txhob muaj kev sib tsoo.
- Automation thiab Intelligence Levels: Xaiv qhov tsim nyog automation raws li tus nqi ua haujlwm thiab kev tswj xyuas ntau lawm. Los ntawm automated pub mis thiab PLC ntse tswj tshuab mus rau tej thaj chaw deb saib xyuas thiab kuaj mob, automation siab dua txo cov kev cuam tshuam ntawm phau ntawv, stabilizes cov txheej txheem, thiab txhim kho cov khoom sib xws. Cov txheej txheem siab tshaj tuaj yeem ua kom zoo dua qhov kev ua haujlwm tsis zoo los ntawm kev txheeb xyuas cov ntaub ntawv, ua tiav kev txuag hluav taws xob thiab txo kev siv.
- Kev siv hluav taws xob thiab cov nqi khiav lag luam: Tsom ntsoov rau cov khoom siv hluav taws xob ua kom muaj zog sib piv, xws li kev ntsuas kev ua haujlwm ntawm lub cev muaj zog, kev tsim hluav taws xob tsim hluav taws xob ntawm cov cua sov, thiab muaj peev xwm rov qab tau lub zog. Cov xwm txheej no cuam tshuam ncaj qha rau - cov nqi hluav taws xob ntev. Tsis tas li ntawd, ntsuas qhov kev pab cuam lub neej thiab hloov cov nqi ntawm cov khoom hnav (xws li, cov hniav, cov ntxaij vab tshaus, ntsia hlau chim).
- Kev ntseeg tau thiab kev saib xyuas yooj yim: Cov khoom siv ruaj khov ua haujlwm yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig. Xaiv cov cuab yeej tsim muaj zog, tsim kom muaj peev xwm ua tau raws li qhov tseem ceeb ntawm kev saib xyuas txhua hnub yooj yim - xws li tshuaj ntsuam kev siv tau rau kev hloov pauv, lubrication point ncav cuag, thiab qhov chaw kuaj pom tseeb.
- Yav tom ntej Scalability: Cia siab tias kev lag luam loj hlob muaj peev xwm. Cov khoom puas txhawb kev hloov kho modular? Nws puas tuaj yeem hloov kho rau cov khoom siv tshiab los ntawm kev ntxiv lossis hloov cov khoom siv? Xaiv cov qauv tsim nrog kev hloov pauv yooj yim thiab txhim kho cov peev txheej zoo dua tiv thaiv ntev - kev nqis peev.
Thaum kawg, kev xaiv cov cuab yeej tsim nyog yog txheej txheem uas sib koom ua ke nrog cov yam ntxwv ntawm cov khoom siv, cov txheej txheem yuav tsum tau ua, lub hom phiaj ntawm kev tsim khoom, thiab cov peev nyiaj lag luam. Nws xav kom cov tub ua lag luam tsis tsuas yog tsom mus rau ib tus neeg siv cov cuab yeej ua tau zoo tab sis kuj nkag siab nws lub luag haujlwm thiab kev sib koom ua ke hauv tag nrho cov kab rov ua dua tshiab.
