Hauv cov luam ntawv laser roj laser thiab luam tawm cov tshuab, ua cov khoom tseem ceeb ntawm kev txhim kho, kev cuam tshuam ncaj qha, ntaus nqi nyiaj. Toner cov neeg nqa khoom feem ntau muaj sib xyaw ntawm cov khoom sib nqus (xws li ferrite) nrog toner, ua tiav uniform toner hloov mus los ntawm kev them nyiaj triboelectric them nyiaj. Txawm li cas los xij, cov paib kev ua tau zoo yuav tsum muaj sib txawv thoob plaws cov ntawv thov sib txawv, ua cov kev xaiv ntawm lub tooter tsim nyog.
I. Cov haujlwm tseem ceeb thiab cov kev faib tawm ntawm cov kws nqa khoom
Toner Carrieve Carrers hais thiab precisely ua rau lawv mus rau lub photoreceptor nruas los ntawm tus nqi hloov kev hloov tshuab. Raws li lawv cov khoom siv cov khoom siv, cov neeg nqa khoom tuaj yeem faib ua ob pawg:
1.Magnnetic Nqa: Cov no siv cov khoom sib nqus ferrite lossis cov khoom sib nqus zoo sib xws li lawv cov tub ntxhais thiab tsim nyog rau ob qho kev txhim kho (xav tau siv nrog Toner). Lawv tau zoo nyob hauv lawv cov tshuaj sib nqus tau zoo sib nqus, ua rau lawv haum rau high- phoo ntawv luam yeeb. Txawm li cas los xij, lawv tuaj yeem tsim cov hmoov av hlau vim hnav.
2. Ua tibzoo- Cov tsheb thauj khoom: Cov no siv cov khoom lag luam lossis kev kho mob ceramic nrog kev kho kom haum lawv cov kev them nqi kev lag luam. Cov cab kuj no tsim cov suab nrov tsawg thiab muaj kuab paug, tab sis xav tau cov txheej txheem siab dua.
Cov neeg nqa khoom kuj tseem tuaj yeem yog cov kev faib tawm ntxiv los ntawm particle loj (piv txwv li, 30-100 / tsis zoo) kom tau raws li cov kev xav tau ntawm cov kev xav tau sib txawv.
Ii. Cov kev tsis tseem ceeb rau kev xaiv toner cov muaj
1. Them nyiaj ruaj khov thiab sib raug zoo
Lub qhov muaj peev xwm saum npoo ntawm cov cab kuj cuam tshuam rau lub toner kev ua tiav kev ua tiav. Xyuas kom meej tias tus nqi them polarier thiab toner ntais ntawv (piv txwv li, cov khoom tsis zoo uas yuav tsum tau ua khub), thiab paub ntev}. Tsis zoo - Cov tsheb ciav hlau zoo yuav ua rau them nqi sai sai, ua rau muaj kev ua yeeb yaj kiab lossis ua yeeb yaj kiab.
2. Paus Loj Tshaj Tawm thiab Flowability
Qhov kev sib txuam ntawm cov cab kuj particle loj (feem ntau tswj tau nyob rau hauv a ± 10 micron kev zam txim) txiav txim nws cov kev sib xyaw nrog lub toner. Cov nruas loj heev tuaj yeem yooj yim khawb lub tshuab photoreceptor, thaum cov khoom me me me me tuaj yeem ua rau toner agglomeration. Nws raug nquahu kom xaiv cov neeg nqa khoom nrog tus spherericity ntau dua los yog sib npaug rau 0.9 los txhim kho kev kub heev thiab txo cov tsim muaj nyob hauv cov kev tsim tawm Chamber.
3. Hnav tsis kam thiab kev pabcuam lub neej
Lub hardness ntawm cov cab hlau sib nqus (feem ntau 4 {{- 5 ntawm Mohs nplai) yuav tsum phim cov khoom siv cov roj uas tsim tau thiab cov hmoov av ntau. Rau cov ntawv thov muaj kev lag luam (piv txwv li, txhua hli sau cov ntawv luam tawm ntau tshaj 50,000 nplooj ntawv), cov cab kuj nrog cov khoom siv-tiv thaiv yuav tsum tau xaiv; Nws cov kev pabcuam lub neej tuaj yeem yog 2-3 zaug uas cov neeg nqa khoom.
4. Ib puag ncig kev yoog tau
Nyob rau hauv high - kub thiab siab -}}} g, los ntawm hydrophobic kho kom txo hydrophobicity). Hauv qhov qis {{5 5}} qhov chaw dej haus, cov cab kuj yuav tsum muaj kev ua kom muaj viscosity tsawg los xyuas cov toner du.
III. Daim Ntawv Thov - Raws cov lus pom zoo
• Chaw ua hauj lwm luam ntawv (me me rau nruab nrab loads): Tsawg {{} -} Cov suab nrov thiab cov duab tsis tshua muaj. Piv txwv li, tsis zoo them tus neeg nqa khoom nrog cov me me ntawm 50-70 microns tau pom zoo.
• Ua daim ntawv nrawm nrawm (siab {- Cov Paus Muaj Nqis
• Rau kev lag luam batch luam tawm: hnav cov khoom siv ceramic) thiab cov khoom lag luam tsis sib haum xeeb dua lossis sib npaug rau 15% yog qhov pom zoo).
IV. Kev txheeb xyuas thiab kev tswj hwm txij nkawm
Tom qab xaiv cov cab kuj, nws raug pom zoo kom ua cov me me - batch ntsuam xyuas kom ntsuas qhov kev ua tau zoo, suav nrog:
• Kev ntsuam xyuas cov luam ntawv txuas ntxiv (los xyuas fusing saimness thiab kev hloov xim);
• Kev Kho Mob Chamber Kev Tshuaj Xyuas Cov Khaub Ncaws (los saib cov khib nyiab
• Them cov kev sim ua kom tsis txhob ua haujlwm (mus sim
Nquag hloov cov cab kuj (feem ntau txhua txhua 200,000-3,000 nplooj ntawv lossis 1-2 xyoos) thiab tsis txhob muab cov khoom sib xyaw sib xyaw thiab cov zis sib txawv.
Tag
Xaiv lub tuj cov cab kuj tsis yog teeb meem ntawm kev ua kom zoo dua ib qho ntsuas; Theej, nws yuav tsum tau ntau - qhov kev txiav txim siab uas txiav txim siab txog cov yam ntxwv, cov khoom siv mechanical, thiab kev ua haujlwm. Users should determine the optimal solution based on their specific printing needs through scientific evaluation and empirical testing, balancing quality, cost, and reliability objectives.
