1. Kub: yuav tsum tsim nyog thiab ruaj khov
Pom zoo ntau yam: Rhiav kub 10-35 degree; Qhov zoo tshaj plaws khaws cia ntawm 20-30 degree.
Yog vim li cas: qhov kub qis dhau yuav ua rau PPR raw khoom ua nkig thiab cuam tshuam kev noj qab haus huv, yuav tsum tau siv zog ntau hauv cov cua sov; Qhov kub thiab txias heev yuav cuam tshuam rau qhov txias thiab ua kom zoo, uas ua rau cov yeeb nkab tsis ruaj khov.
Yam yuav tsum tau muaj: Tsis txhob tshav ntuj ncaj qha rau ntawm cov khoom siv lossis lub tshuab cua txias cua tshuab ncaj qha mus rau pwm / calibration lub tes tsho; Qhov kub ntawm qhov sib txawv hauv zos yuav tsum tsis txhob loj dhau.
2. Humidity: Yuav tsum qhuav thiab noo noo- pov thawj
Pom zoo ntau yam: txheeb ze humidity Tsawg dua lossis sib npaug li 80%; lub ziab, qhov zoo dua.
Yog vim li cas: Txawm hais tias PPR nws tus kheej muaj qhov nqus dej tsis tshua muaj (tsawg dua li cov khoom siv yas xws li PA), yog tias muaj cov dej noo tseem ceeb ntawm qhov chaw (vim muaj cov dej noo ntau), cov nyiaj streaks thiab npuas tseem tuaj yeem tsim thaum lub sij hawm siab - kub melting, cuam tshuam rau ob qho tib si tsos thiab txhua yam khoom.
Qhov yuav tsum tau muaj: Khaws cov khoom siv raw khoom kom qhuav; siv cov khoom sai li sai tau tom qab qhib lub pob; Cov khoom siv rov ua dua yuav tsum tau qhuav ua ntej muab sib xyaw.
3. Qhov cua thiab tso pa tawm: Tsim nyog thiab ua raws
Yam yuav tsum tau ua: Kev tso cua tso cua los yog lub hauv paus tso pa tawm yuav tsum tau teeb tsa kom tshem tawm cov kab ntawm VOCs (volatile organic compounds) thiab hmoov av tsim tawm saum lub extruder tuag thiab hopper los ntawm kev cob qhia.
Emissions Standards: Yuav tsum ua raws li cov kev cai ib puag ncig hauv zos (xws li GB 31572 lossis cov qauv hauv zos). Feem ntau, emissions yuav tsum raug tso tawm ntawm qhov siab siab tom qab kev kho yooj yim xws li cov pa roj carbon adsorption lossis UV photolysis.
Ntawm -Site Observation: Yuav tsum tsis muaj qhov hnov tsw tsw ntxhiab lossis "tsim tsw ntxhiab" hauv qhov chaw ua haujlwm; txwv tsis pub, qhov no qhia tau tias tsis muaj qhov cua los yog muaj peev xwm kho tau.
4. Kev huv huv thiab qhov chaw: yuav tsum huv si thiab tsis muaj kev cuam tshuam
Pem hauv ntej: Khaws cov theem hauv pem teb, tsis muaj cov roj stains, sawv ntsug dej, thiab plua plav kom tsis txhob muaj cov kab mob sib xyaw rau hauv cov kav dej lossis ua rau muaj kev sib tsoo.
Raw Materials thiab Recycled Material Areas: Cov no yuav tsum raug cais tawm ntawm qhov chaw ua haujlwm extruder kom tsis txhob muaj plua plav los ntawm huab cua; cov khoom siv rov ua dua tshiab yuav tsum tau muab tso rau hauv ib qho chaw cais lossis nruab nrog cov khoom siv plua plav.
Aisles: Cov cuab yeej layout yuav tsum tso cai tsawg kawg yog 1 meter ntawm qhov chaw rau kev ua haujlwm thiab kev saib xyuas, kom ntseeg tau tias cov khoom siv tau zoo thiab ua raws li cov kev cai ntawm kev nyab xeeb hluav taws.
5. Kev Tiv Thaiv Kev Nyab Xeeb: Tsis txhob muaj kev phom sij
Kev Nyab Xeeb Hluav Taws Xob: PPR yog cov khoom siv hluav taws xob; qhib nplaim taws yog txwv nyob rau hauv lub rhiav. Cov vaj huam sib luag hluav taws xob thiab cov xaim hluav taws xob yuav tsum yog tawg- pov thawj lossis tshuaj xyuas kev laus, thiab cov hluav taws tua hluav taws yuav tsum tau muab.
Anti-Kev ntsuas zoo li qub: hluav taws xob zoo li qub tsim thaum lub sijhawm xa khoom ntawm PPR pellets tuaj yeem nyiam plua plav; hoppers thiab feed pipes yuav tsum tau grounded.
Suab nrov: Lub extruder nws tus kheej tsis tsim suab nrov (feem ntau qis dua 75 dB), tab sis lub shredder tsim suab nrov dua. Nws raug nquahu kom nruab ib lub kaw lus tsis muaj suab nrov nyob ib ncig ntawm lub shredder lossis teem sijhawm nws lub sijhawm ua haujlwm thaum lub sijhawm sib cais lossis hauv thaj chaw uas tau xaiv.
