Cov pob dub thiab impurities yog tus yam ntxwv me me thiab tsaus xim av, uas feem ntau tsis cuam tshuam txog. Thaum cov lus hais loj, cov impurities yog fawm kib, nkig, tsis yooj yim thiab ntxeem tom qab tsoo, thiab lawv cov khoom faib tawm muaj ob qhov tseem ceeb:
1. Ib txhia ntawm lawv tau faib qee yam hauv tag nrho, qee qhov raug xa mus rau lub zos, thiab qee zaus qee zaus tsuas tshwm sim hauv qee qhov chaw hauv zos;
2. Qee zaum, xws li cov kab dub thiab impurities tsuas yog tshwm sim ntawm cov khoom lag luam, thiab qee zaum lawv muaj nyob tsis hais qhov tob ntawm sab hauv thiab sab hauv. Txawm li cas los xij, cov xim dub sab hauv ze dua rau saum npoo yog qhov sib dua hauv cov xim dua li cov pob saum npoo dub, thiab qhov pom dub tob dua yog pom tsis txhua.
Qhov ntxim siab, los ntawm kev sib txuas ntawm ob lub ntsiab lus no, nws tuaj yeem pom tias qhov tsis zoo uas tsuas pom nyob rau hauv qee qhov chaw hauv cheeb tsam yuav tsum muaj cov xim dub nyob rau saum npoo, thiab kev faib tawm ntawm cov pob dub yuav tsum yog tag nrho tsis meej thiab tawg tsis hais qhov tob ntawm lub npoo thiab sab hauv.
Qhov no yog vim hais tias cov impurities uas twb muaj lawm sab hauv yuav tsum muaj nyob ua ntejmoulding, thiab lub impurities tshwm sim tsuas yog thaum lub sij hawm molding yuav tsum tsuas yog muab faib rau saum npoo. Ua li no, impurities tuaj yeem faib ua ob pawg: ua ntej molding thiab thaum molding:
I. Ua rau cov ntsiab lus dub thiab tsis huv ua ntej molding:
1. Thaum cov ntaub ntawv raw khoom tiav, vim muaj ntau yam laj thawj, lub cev txawv teb chaws tsis huv thiab cov pob dub tshwm nyob hauv cov khoom siv raw;
2. Cov pob dub tshwm sim los ntawm kev ua kom qias;
3. Cov khoom siv raw yog muab sib xyaw nrog masterbatch lossis speckled crushed block thiab scraps;
4. Cov khoom siv yog qhov tsis txaus ntseeg, thiab cov khoom siv nrog qis melting point yog sib xyaw nrog cov khoom siv nrog siab melting point;
5. Kev ua kom tsis zoo yuav raug muab xyaw nrog txheej txheem ntawm kev ntim, thauj khoom thiab chaw cia khoom. Nws qhov pom tseeb yog tias tom qab cov khoom siv tsis tiav, nws tuaj yeem pom tias muaj lub cev txawv teb chaws thiab impurities rau saum npoo ntawm cov khoom seem;
6. Tshwj tsis yog 5 thiab 11, lawv yuav tsis ncaj qha rau cov khoom siv lub plhaw, thiab lwm qhov chaw tuaj yeem ua kom qias tuaj ntawm cov khoom nyoos thaum lub sijhawm pub mis, uas ua rau muaj cov xim dub thiab tsis huv ntawm cov khoom. Lub chaw muaj kuab paug muaj xws li: hmoov av hauv huab cua, tshem tawm cov khoom tsis raug, cov khoom lag luam tawm txawv teb chaws, cov khoom siv txawv teb chaws, hmoov av hmoov av, zas xim, thiab lwm yam. txhua qhov txuas los ntawm cov ntaub ntawv nyoos nkag mus rau kev pub mis (suav nrog cov txheej txheem rov ua dua tshiab).
Thaum muab cov roj pleev, cov seem uas cov khoom qub lossis cov quav tawg yuav tsum raug ntxuav kom huv, tshwj xeeb yog lub thawv ntim khoom siv, plhaw, qhov lom zem, thiab qhov nrawm ntawm qhov qis dua qhov clip. Thaum lub sijhawm ua haujlwm ntau lawm, tshwj xeeb yuav tsum them rau qhov huv ntawm qhov chaw pub khoom noj-cov khoom siv npaj lub thawv. Tom qab cov khoom lag luam raug tso tseg, qhov chaw nres nkoj ntawm lub tshuab pub mis, uas raug rau sab nraud ib puag ncig ntawm lub tshuab pub mis, yuav tsum muab ntim rau kom tsis txhob muaj kuab paug, thiaj li ua tiav kev cuam tshuam thiab kaw kev tswj hwm.
7. Kev ntsuas carbonization ntawm cov ntaub ntawv raw, cov pob qij dub dub feem ntau muaj qhov loj me, thiab qhov tshwm ntawm lub cheeb ntawm cov pob dub loj tuaj yeem ncav cuag 1-2 hli. Feem ntau ntawm" dub me ntsis" cov tuab tuab dua, thiab ib lossis ob txheej txheej hnyav dua ntais. Hauv qhov no, cov ntaub ntawv nyoos tau khaws cia ntev ntev lossis hauv zos cov huab cua sov siab, thiab tau decomposed, coked thiab carbonized rau hauv cov blocks. Nws yog tsim tom qab ntws tawm ntawm lub hau ntswj lossis lub hle khaub noom yog sheared thiab tawg.
Cov laj thawj rau carbonization ntawm raw cov ntaub ntawv yog:
1) Yog tias qhov kub yaj ua rau siab dhau lawm thiab cov khoom kub dhau dhau lawm, nws yuav ua rau muaj qhov kub ntxhov thiab ua kom cov carbide tawg. Tshwj xeeb rau qee cov khoom siv cua sov, qhov ntsuas kub tau nqaim, yog li nws tsim nyog los tswj qhov ntsuas qhov kub ntawm qhov saj ntawm lub thoob tsis txhob kub dhau.
2) Coking ntawm cov khoom siv tau khaws cia: Yog tias yas molten nyob hauv ib qho chaw rau ntev dhau, coking cov khoom siv ntau yuav tshwm sim, ua rau cov xim dub, uas yuav ua rau cov khoom khaws cia cov chaw, xws li kev sib koom tes ntawm lub taub dej thiab cov ntsia hlau ntsia hlau, ntsia hlau ntsia thawv phab ntsa, lub nplhaib roj hmab molten, qhov sib txuas lus nruab nrab ntawm lub pas dej no thiab lub rooj vag, ces kaum ntawm cov kub khiav, lub kaum tuag ntawm cov neeg khiav lub ntsiab, thiab lwm yam.
3) Qhov sib txawv nruab nrab ntawm lub thoob thiab lub hau ntswj yog qhov loj heev, uas yuav ua rau cov khoom nyob hauv lub thoob, thiab cov khoom siv khov kho yuav txiav txim siab los ntawm overheating rau lub sijhawm ntev, uas yuav ua rau cov pob dub.
8. Cov quav ntxiv cuam tshuam zoo, decompose thiab hloov xim. Cov tshuaj ntxiv rau suav nrog cov tshuaj tiv thaiv antistatic, ultraviolet / infrared absorber thiab cov tsoos xim, uas nws cov khoom feem ntau nquag dua li cov khoom siv raw. Raws li kev txiav txim ntawm shearing quab yuam ntawm kev ntsuas kub, thaum cov ntaub ntawv tsis decomposed, lawv tau decomposed thiab ua tsaus, daj-xim av los yog txawm tias dub, thiab cov xim dub thiab impurities yog tsim thaum lub sij hawm molding.
Thib ob, dub pob thiab impurities tshwm sim los ntawm cov laj thawj sab nraud muaj ntau heev nyob rau hauv ntau lawm, thiab lawv tau tawv ncauj tom qab lawv tshwm sim.
1. Cov khoom siv pwm tsis zoo, thiab cov hmoov hlau yuav poob tawm ntawm qhov chaw ntawm cov nplooj ntawv, molding saum npoo lossis tho qhov chaw, uas ua rau cov pob zeb dub.
2. Lub thimble yog ntxhib thiab yooj yim mus hlawv, thiab hmoov hlau txau yog nqis, uas ua rau cov pob dub.
3. Lub zawv zawg zom grims hlau ua npuas hmoov, ua rau cov pob dub.
4. Muaj dej xau, xeb lossis lwm qhov stains nyob rau hauv qhov vias. Xeb thiab stains yuav ya tawm los ntawm tus swb thiab tsim cov pob dub thaum lawv poob rau ntawm cov khoom lag luam.
Kev saib tsis taus dub:
Yog tias cov pob dub dub tshwm rau tag nrho saum npoo ntawm cov khoom lag luam thiab muaj cov pob dub hauv qhov tob ntawm cov khoom, lawv yuav tsum yog rau cov pob dub dub ua ntej molding; Yog tias cov pob dub tsuas yog tshwm sim rau saum npoo, lawv yuav tsum muaj xim dub hauv kev molding. Yog tias nws tsuas yog faib rau qee qhov tshwj xeeb ntawm cov nplaim tib lub sijhawm, nws yog qhov tsis muaj qhov xav tau xim dub nyob rau hauv molding; Yog tias qhov chaw dub yog qhov loj (feem ntau 0.5 ~ 1 hli), nws yuav tsum yog rau cov khoom siv raw carbonization dub chaw;
Yog tias cov pob dub dub tsaus, nkig, yoov thiab ntxeem tau tib lub sijhawm, lawv tuaj yeem raug txiav txim zoo li cov pa roj carbon dub dub; yog hais tias qhov ntom ntawm cov tawv dub yog qhov loj heev, kev kuaj xyuas ntawm cov khoom siv yog tsis muaj qhov tsis muaj qhov tsis muaj qhov cuam tshuam, uas feem ntau muaj qhov xwm txheej uas cov khoom qub tau ntxuav thaum kawg tsuas yog tom qab rov ua kom tiav; txwv tsis pub, vim li cas rau cov khoom siv yuav tsum tau kuaj xyuas.
III. Ntsiab:
1. Rau qhov ua kom tsis muaj zog, cov pob qij dub yog tsim vim kev sib xyaw ntawm cov khoom siv txawv teb chaws mus rau hauv cov khoom siv, yog li nws yuav tsum tau tswj hwm qhov huv ntawm txhua qhov txuas ntawm kev tsim khoom, ntim khoom, ntim khoom, thauj, qhia thiab sib xyaw rau lub thoob them. Cov.
2. Rau cov pa roj carbon dub dub, kev ntsuas kub yuav tsum tswj hwm kom nruj. Hauv qhov khoom siv tiag, muaj qhov sib txawv ntawm qhov ntsuas kub thiab cov ntsuas kub ua. Rau tib cov khoom siv, sib txawv rov qab siab, txawv lub sijhawm sib txawv, sib txawv ntawm cov tshuaj txhaj ib zaug thiab ntau qhov chaw ntawm lub cev ntxig sib txawv yuav ua rau muaj kev sib txawv ntawm cov pa roj carbon ntau thiab cov kev cuam tshuam rau tib lub ntsuas kub. Tshwj xeeb, thaum lub ntsuas kub zoo li qub, lub nraub qaum yog qhov me me, lub voj voog yog luv, thiab kev txhaj ib zaug yog loj. Thaum cov thermocouple tau ntxig rau sab qaum ntawm cov ntsia hlau ntsia hlau, cov khoom siv melting muaj qhov tsis muaj zog ntawm kev ua tsis zoo / decomposition, thiab nws tsis yooj yim los tsim carbonization dub pob.
Txhawm rau tiv thaiv carbonization dub pob, nws yog ib qho tsim nyog yuav tsum tau tiv thaiv kom tsis txhob tsub zuj zuj ntawm cov ntaub ntawv, tshem tawm cov pob tuag hauv cov ntsia hlau ntsia hlau, tsis muaj pob tw thiab khiav, ua kom nws muaj kev hloov pauv maj mam ntawm kaum, thiab tshem tawm thaj chaw uas cov khoom yuav nyob.
3. Rau qhov cov xim dub tso nyiaj los ntawm kev ua kom zoo ntxiv lossis cov khoom siv carbonized uas twb muaj lawm tso rau ntawm cov xov thiab ntsia hlau ntsia thawv phab ntsa. Feem ntau, nrog cov kev tsim tawm mus, cov pob dub yuav tawg ntawm lawv thawj qhov chaw txuas thiab nkag rau hauv cov yaj hauv ntau yam muaj zog shearing ua yeeb yam hauv lub hau ntswj thiab ua kom tawm. No" paug" txheej txheem yog txheej txheem uas cov pob dub thiab impurities tshwm sim hauv cov khoom. Piv txwv, hauv kev tsim cov khoom siv hloov pauv thiab xim, cov txheej txheem no ntawm" tso tawm" impurities yog kev tsis pom, yog li peb yuav tsum sim peb qhov zoo tshaj plaws kom ua txoj haujlwm no. Puas yog" tu" ;. Muaj ob txoj hauv kev tu:
1) Ntxuav cov ntsia hlau rau cov kua nplaum npliag yaj (nplaim tawg tom qab kua nplaum yaj tas).
2) Melting kua nplaum ntawm lub rooj nkag, txau kua nplaum rau saum huab cua, thiab tom qab ntawd yaj kua nplaum ntawm lub rooj nkag thiab txau kua nplaum rau saum huab cua, uas rov ua dua. Kev ua pov thawj pom tseeb: Lub nraub qaum yog lub luag haujlwm tseem ceeb hauv kev ntxuav, thiab cov yaj thiab ntsia hlau txiav tau siab heev. Cov nplov tawm melting qeeb, yog li lub sijhawm melting yog ntev. Qhov no ua tau zoo thiab tuaj yeem ntxuav tawm txawv teb chaws lub cev sai sai. Nco tseg: Lub siab rov tom qab muaj lub hauv paus thaum tsis muaj sijhawm-nws yuav tsum siab npaum li sai tau, kom txog rau thaum cov ntsia hlau ntsia thawv yeej xwb' t cia li kho cua sov.
3) Rau cov xim dub hauv txoj kev sib sau, cov pob dub hauv txoj hauv kev sib sau yuav tsum txuas rau kab noj hniav ua ntej, thiab tom qab ntawd qhwv thiab tsau rau ntawm cov khoom nto los ntawm yaj, yog li cov ntsiab lus dub tshem tawm no tuaj yeem tiv thaiv nws los ntawm kab noj hniav Cov. Txhawm rau txiav txim siab cov pwm nrog cov khoom tsis zoo, peb yuav tsum xub txiav txim siab qhov ua thiab qhov chaw.
Tag nrho cov kab noj hniav thiab cores nrog qhov sib txav ntawm tus kheej, suav nrog lub cev swb, neutron thiab ejector pin / block, feem ntau yuav hlawv. Tom qab qhov kev hlawv ntawd tau paub tseeb, cov khoom seem yuav tsum tau kho. Ntxiv rau, kev txhuam ntawm kev sib tsoo ntawm cov swb yuav tsum tau txo thiab lubricating roj yuav tsum ntxiv.
Ntxiv mus, txhawm rau kom txo qhov txheeb ze ntawm kev txav ceev ntawm cov swb ntu, xws li jacking / thim rov qab, qhib thiab kaw qhov tuag, lub vauj vias yuav tsum maj mam txav kom deb li deb tau, thiab xeb thiab lwm qhov chaw ntawm cov nplais thiab cov phaj tuag yuav tsum tau muab tshem tawm , xeb thiab lwm qhov stains yuav tsum tau muab tshem tawm, thiab cov taub hau dej yuav tsum muab khi kom nruj. Raws li rau cov xim dub tshwm sim los ntawm roj lossis dej splashing rau qhov chaw du ntawm cov pwm kab noj hniav, qhov chaw uas cov roj thiab dej tau yooj yim tawm tuaj yuav tsum tau so ntau zaus kom tiv thaiv lawv los ntawm qhov tshwm sim hauv cov pwm.
