1. Ambient Kub
Qhov zoo tshaj plaws: 20-25 degree; Cov khoom siv tuaj yeem tiv taus 10-40 degree.
Cov teebmeem: Kub kub ntau dhau tuaj yeem ua rau PP decompose (ua nkig, tsim cov pob dub), thiab txo cov kev ua kom txias txias; Tsis tshua muaj kub ua rau cov plasticization tsis zoo thiab cov yeeb nkab tsis zoo.
Kev pom zoo: Nruab cua txias lossis kiv cua; kho cov extrusion kub raws li txhua 5℃hloov nyob rau hauv ambient kub.
2. Ambient Humidity
Qhov zoo tshaj plaws: 40% -60% RH.
Cov teebmeem: Cov av noo ntau dhau → raw cov ntaub ntawv nqus dej noo, ua rau muaj npuas thiab nyiaj streaks hauv cov khoom tiav; cov cuab yeej siv tau yooj yim rau xeb thiab hluav taws xob to. Tsis tshua muaj av noo → hluav taws xob zoo li qub nyiam cov plua plav, uas yuav ua rau cov hluav taws xob puas.
Cov lus pom zoo: Nruab ib lub dehumidifier lossis humidifier; kho cov ntaub ntawv raw nrog lub tshuab ziab khaub ncaws ua ntej siv (ci ntawm 80-120℃rau 2-4 teev).
3. Kev kho cua thiab tso pa tawm
Yam yuav tsum tau muaj: Cov pa roj carbon monoxide (tsis yog -methane tag nrho cov hydrocarbons) tsim thaum lub sij hawm extrusion txheej txheem yuav tsum tau sau los ntawm ib tug fume hood → undergo ob -theem activated carbon adsorption → thiab tso tawm los ntawm ib pawg ntawm tsawg kawg yog 15 meters nyob rau hauv qhov siab kom tau raws li emission qauv.
Cov Qauv: Ua raws li GB 31572-2015 "Emission Standards for Pollutants from the Synthetic Resin Industry."
Cov lus pom zoo: Khaws qhov cua zoo hauv lub rooj cob qhia thiab hloov cov pa roj carbon activated tsis tu ncua.
4. Tswj kev huv huv
Kev cuam tshuam: Plua plav thiab impurities hauv huab cua tuaj yeem ua raws li qhov siab ntawm - cov kav dej kub, ua rau muaj qhov tsis xws luag xws li pitting thiab particles.
Kev pom zoo: Rau siab - cov kab ntau lawm, tsim kom muaj thaj chaw huv huv; Cov neeg ua haujlwm yuav tsum hnav cov khaub ncaws huv huv thiab qhov ncauj qhov ntswg, thiab nruab cov tshuab lim cua.
5. Suab nrov thiab kev vibration
Lub suab nrov: Extruders, nqa -tawm chav nyob, cutters, shredders, thiab lwm yam.
Cov qauv: Cov suab nrov ntawm thaj tsam cog yuav tsum tsis pub tshaj 65 dB thaum nruab hnub thiab 55 dB hmo ntuj (GB 12348-2008).
Kev cuam tshuam: Kev co ntau dhau tuaj yeem txo cov cuab yeej precision thiab puas cov khoom precision.
Cov lus pom zoo: Nruab kev vibration-damping pads thiab soundproof enclosures ntawm cov khoom; tsis tu ncua tshuaj xyuas cov khoom sib hloov xws li bearings.
6. Kev nyab xeeb hluav taws
Risks: Ob qho tib si PP raw khoom thiab cov khoom tiav yog combustible; hmoov av zoo nyob rau hauv lub rooj cob qhia ua rau muaj kev phom sij tawg; siab - kub Cheebtsam ntawm lub extruder yog qhov muaj peev xwm ignition.
Yam yuav tsum tau muaj: Khaws cov ntaub ntawv nyob rau hauv qhov chaw nyob deb ntawm qhov hluav taws kub; txhim kho qhov chaw nrog cov tua hluav taws thiab cov hluav taws tua hluav taws; khaws qhov hluav taws kub kom meej; tsis tu ncua ntxuav cov plua plav.
7. Fais fab mov stability
Qhov yuav tsum tau muaj: Feem ntau yuav tsum tau peb -theem 380V ± 10% nrog rau hauv av kom raug.
Kev cuam tshuam: Kev hloov pauv hluav taws xob tuaj yeem ua rau extrusion tsis ruaj khov, tswj qhov kub thiab txias, thiab txawm tias muaj kev puas tsuaj rau cov khoom zoo xws li inverters thiab PLCs.
Cov lus pom zoo: Tsis txhob sib koom ua ke nrog lub siab - zog, siab -inrush- khoom siv tam sim no; nruab ib lub zog stabilizer lossis lim yog tsim nyog.
8. Pem teb thiab chaw layout
Pem teb: Hauv pem teb yuav tsum yog theem, khoom, thiab muaj peev xwm txhawb nqa cov khoom hnyav kom ntseeg tau tias theem kev teeb tsa.
Qhov chaw: Khaws ib qho 1–2- 'meter' txoj kab dav dav nyob ib puag ncig cov cuab yeej siv rau kev ua haujlwm thiab kev saib xyuas, thiab qhia meej meej cov khoom siv raw, cov khoom tiav, thiab cov khoom seem.
Kev pom zoo: Tam sim ntawd sau thiab txiav cov khoom seem (cov kav dej tsis zoo, txiav xaus) kom rov siv tau los tuav lub rooj cob qhia huv.
