Pelletising, chirongwa chakakosha mukugadzirwa kwezvigadzirwa zvepurasitiki, inotarisa pakudzokorodza uye kugadzirwa kwepurasitiki pellets, ayo ari iwo emhando yemhando dzekushandisa senge kugadzirwa kwemafirimu, kuumba jekiseni uye extrusion. Kune akati wandei matekinoroji tekinoroji aripo, pakati peiyo iyo firimu bi-stage pelletising mutsara wekugadzira inomira pachena seyakashongedzerwa nekubudirira uye nekubudirira kugadzira emhando yepamusoro pellets kubva kumarara epurasitiki.
Kushandura zvinhu zvakasvibirira zvakadai semarara epurasitiki kuita zviduku, yunifomu pellets ndiyo nzira yekuputira, uye iyo yose nzira yekuputira inosanganisira, kudya, kunyunguduka, extruding, kutonhora uye kucheka kugadzira mapepa anogona kubatwa nyore nyore, kutakurwa uye kugadziriswa mumatanho anotevera. yekugadzira.
Pelletising tekinorojiinogona kukamurwa zvakafara kuita mapoka maviri: single-stage pelletitis uye maviri-nhanho pelletising. Single-stage pelletising inoshandisa imwe extruder kunyungudutsa zvinhu uye kugadzira pellets, nepo maviri-nhanho pelletising inoshandisa maviri extruder, ichibvumira kunyatso kudzora kwekunyungudika uye kutonhora maitiro, zvichikonzera emhando yepamusoro pellets.
Iyo firimu nhanho mbiripelletising lineyakagadzirirwa kugadzirisa mafirimu epurasitiki akadai se polyethylene (PE) uye polypropylene (PP). Iyo tekinoroji inonyanya kukodzera kudzokorodza mushure mevatengi epurasitiki mafirimu, ayo anowanzo kunetsa kugadzirisa nekuda kwekushomeka kwawo uye tsika yekunamatira pamwechete.
Kudyisa uye kusati kwagadziriswa kunosanganisira kutanga kudyisa hurongwa nemapuranga epurasitiki efirimu, iyo inowanzobvamburwa kuita zvidimbu zviduku kuti zvive nyore kubata nekugadzirisa. Pre-kurapwa kunogona kusanganisira kuomesa zvinhu kuti ubvise hunyoro, izvo zvakakosha pakunyunguduka kwakanyanya uye pelletising.
Muchikamu chekutanga, iyo shredded yepurasitiki firimu inodyiswa mune yekutanga extruder, iyo yakashongedzerwa nescrew inonyungudutsa zvinhu nekuveura mechini nekudziya. Plastiki yakanyungudutswa inozomanikidzwa nepahwindo kubvisa tsvina uye kuona kunyungudika kwakafanana.
Isa, ndapota funga nezvekambani yedu chigadzirwa ichi,LQ250-300PE Firimu Double-Stage Pelletizing Line
Kubva kune yekutanga extruder, iyo yakanyungudutswa inopinda mune yechipiri extruder, nhanho inobvumira kuwedzera homogenisation uye degassing, iyo yakakosha kubvisa chero yakasara inoputika kana hunyoro hunogona kukanganisa kunaka kwepellet yekupedzisira. Yechipiri extruder inowanzo mhanya nekumhanya kwakaderera, iyo inobatsira kuchengetedza zvinhu zvepurasitiki.
Mushure mechikamu chechipiri cheextrusion, pelletiser inoshandiswa kucheka plastiki yakanyungudutswa kuita pellets, inogona kutonhodzwa pasi pemvura kana nemhepo, zvichienderana nezvinodiwa chaizvo zvekugadzira. Iyo pellets inogadzirwa yakafanana muhukuru uye chimiro uye inokodzera zvakasiyana-siyana zvekushandisa.
Kana ma pellets achinge aumbwa, anoda kutonhodzwa uye kuomeswa, ozoomeswa kuti abvise unyoro hwakawandisa. Kutonhora kwakanaka uye kuomesa kwakakosha kuti uve nechokwadi chekutipelletschengetedza kuvimbika kwavo uye usakanganiswa.
Chekupedzisira, mapellets anoiswa kuti achengeterwe kana kutakura, maitiro akagadzirirwa kuderedza kusvibiswa uye kuve nechokwadi chekuti pellets iri muchimiro chakanakisa isati yashandiswa.
Pazasi pane mimwe mienzaniso yemabhenefiti embiri-nhanho pelletising mutsara wemafirimu:
- Yepamusoro pellet mhando:maitiro maviri-matanho anobvumira zviri nani kutonga kwekunyunguduka uye kutonhora, zvichiita kuti pave nepamusoro pepamusoro pepellets nekuvandudzwa kwemuviri.
- Kubviswa kwepamusoro kwetsvina:Iyo miviri-nhanho extrusion process inobvisa zvinosvibisa uye inoputika, zvichiita kuti ichenese, inowirirana pellets.
-Kusiyana-siyana:Iyo tekinoroji inogona kugadzira akawanda epurasitiki mafirimu, ichiita kuti ive yakakodzera kune akasiyana siyana ekudzoreredza maapplication.
- Kushanda kwesimba:Bipolar systems dzinowanzogadzirirwa kushandisa simba shoma pane imwe-nhanho masisitimu, zvichiita kuti ive sarudzo inogoneka.
- Yakaderedzwa downtime:iyo inobudirira dhizaini yefirimu bi-stage pelletising line inoderedza kuderera panguva yekugadzira, zvichikonzera kuwedzera kuburitsa uye kubereka.
Pelletising tekinoroji inoita basa rakakosha mukudzokorodza uye kugadzira zvigadzirwa zvepurasitiki. Firimu maviri-nhanho pelletising mitsetse inomiririra kufambira mberi kukuru mundima iyi, kuvandudza kugona, kunaka uye kuita zvakasiyana. Sezvo kudiwa kwemapurasitiki ekugadzirisa mhinduro kuri kuramba kuchikura, kukosha kwekuitateknolojia yepelletizingzvichawedzera zuva nezuva. Nekudyara muhurongwa hwepamberi senge firimu-nhanho mbiri-pelletising mitsara, vagadziri vanogona kubatsira kune ramangwana rakagadzikana vachisangana nezvinodiwa nevatengi vavo, saka kana iwe uchifarira firimu-nhanho mbiri-pelletising mitsara, ndapota usazeza kubata yedu. kambani.
