1. Lub kaum sab xis me dhau
Qhov kawg ntawm lub rooj zaum pob yog ib qho yooj yim hnav (cov khoom siv ntawm lub rooj zaum pob yog npib tsib xee -platinum tooj liab lossis stainless hlau, uas yooj yim dua hnav dua lub pob). Ua li ntawd yuav ua rau cov pob tawg.
2. Kho lub kaum sab xis
Thaum sau tus cwj mem ballpoint, nws yog qhov zoo tshaj plaws los tswj lub kaum sab xis ntawm 55 degree thiab 70 degree. Nyob rau lub sijhawm no, tsuas yog lub pob yog nyob rau hauv kev sib cuag nrog daim ntawv (lub pob yog ib qho nyuaj heev, tungsten carbide los yog ceramic, thiab nws tsis yooj yim rau hnav), thiab qhov chaw kaw tsis hu rau cov ntaub ntawv sau. Yog li txhawm rau xyuas kom meej tias tus cwj mem ballpoint tuaj yeem ua rau lub neej ua haujlwm ntev hauv lub xeev sau ntawv zoo.
3. Lub ncoo yog tuab heev
Thaum sau ntawv, daim ntawv ncoo yog tuab heev, thiab qhov kawg ntawm tus cwj mem kov cov ntawv, uas yooj yim rau hnav thiab rhuav tshem cov hlaws. Nws raug pom zoo: {{0}}.4 pob tsis tuaj yeem theej; 0.5 pob tuaj yeem luam tau ntawm 1 daim ntawv, tsis yog ntau dua; 0.7 pob tuaj yeem luam tau ntawm 3 nplooj ntawv Mus txog 4 nplooj ntawv, tsis muaj ntxiv, thiab nws yog qhov zoo tshaj plaws los sau ntawm 75 degree thaum luam.
4. Dyes
Lub luag haujlwm ntawm cov dyeing yog muab tus cwj mem txaus xim qhov tob. Cov dyes siv hauv cov cwj mem cwj mem tuaj yeem muab faib ua roj-soluble dyes thiab cawv-soluble dyes. Cov dyes siv nyob rau hauv qhov kev xeem no yog phthalocyanine dyes, uas yog insoluble nyob rau hauv cov kuab tshuaj thiab muaj zoo dispersion nyob rau hauv tus number case. Nws muaj zog adhesion rau zaj duab xis- tsim tus neeg sawv cev, yog li nws tsis nkag mus rau sab hauv ntawm daim ntawv, thiab xim yuav tsum ci thiab huab cua- tiv taus.
5. Dispersant
Tus nqi tsim nyog ntawm cov khoom tawg tuaj yeem txo qhov adhesion ntawm tus number case thiab daim ntawv nto, yog li tus number case tuaj yeem raug so tawm hauv ib lub sijhawm thaum nws tau sau rau ntawm daim ntawv, thiab cov dispersant tuaj yeem tswj cov ntawv sau tau zoo thiab ntev {{ 0}}term stability ntawm tus number case. Cov khoom siv hauv qhov kev sim no yog sib xyaw ntawm phthalates thiab ethylene glycol esters npaj rau hauv ib qho kev faib ua feem.
6. Zaj movie qub
Cov yeeb yaj kiab- tus neeg sawv cev tsim yog ib feem tseem ceeb ntawm tus cwj mem rau cov cwj mem uas tshem tau. Nws lub luag haujlwm tseem ceeb yog tsim cov yeeb yaj kiab tsis sib xws rau ntawm daim ntawv thiab ua tus nqa khoom rau dyes. Nws yuav tsum muaj qee qhov adhesion rau daim ntawv, thiab nws tsis yooj yim rau tev tawm, tab sis nws tuaj yeem maj mam muab so nrog cov lwv, muaj zog adhesion rau cov xim, muaj cov solubility zoo hauv cov kuab tshuaj, thiab muaj kev ruaj khov nrog lwm tus. Cheebtsam, thiab tuaj yeem khaws cia rau lub sijhawm ntev. . Roj hmab zaj duab xis qub tau siv rau hauv qhov kev sim no.
7. Cov kuab tshuaj
Nyob rau hauv tus cwj mem rau erasable ballpoint cwjmem, lub luag hauj lwm ntawm cov kuab tshuaj yog kom yaj dyes, zaj duab xis - tsim cov neeg ua hauj lwm, thiab yuav tsum tau sib xws nrog ntau yam auxiliaries, muab ib tug tej yam fluidity, thiab kom muaj ib tug txoj cai volatility, uas. tuaj yeem tswj kev ziab kom zoo thaum lub sijhawm sau ntawv. ceev. Cov kev sim qhia tau hais tias cov txiaj ntsig ntawm kev siv co- cov kuab tshuaj zoo dua li cov kuab tshuaj ib leeg. Hauv qhov kev sim no, cov co- cov kuab tshuaj ntawm cov kuab tshuaj A: cov kuab tshuaj B=1: 1.52.5 yog siv, thiab cov nyhuv yog qhov zoo tshaj plaws.
8. Lwm yam additives
(1) Lubricants thiab corrosion inhibitors
Fatty acids feem ntau yog siv los ua cov roj nplua nyeem hauv cov khoom siv roj ntsha, thiab cov roj nplua nyeem kuj yog co- cov kuab tshuaj. Lub luag haujlwm ntawm cov roj nplaum muaj xws li: A. Lubricate lub pob thiab muab kev sau ntawv zoo; B. Tiv thaiv kom tus number case los ntawm ziab, kom lub ballpoint cwj mem muaj qhov ruaj khov thiab ua haujlwm tau zoo. cwj mem ua haujlwm; C. Ua kom qhov tob ntawm dye dissolution thiab txhim kho cov xim ntawm cov dye. Kev taw qhia txog cov roj fatty acids yog corrosive rau qee cov nib hlau (xws li tooj liab alloys), ua rau muaj cov khoom siv crystalline heterogeneous hauv tus cwj mem los thaiv cov channel, yog li ua rau lub neej ua haujlwm luv ntawm cov cwj mem ballpoint. Cov txheej txheem ntawm kev siv fatty acid supplemented los ntawm corrosion inhibitor tuaj yeem daws qhov teeb meem corrosion thiab ua tau raws li cov kev cai lubrication tib lub sijhawm. Lub corrosion inhibitor siv nyob rau hauv qhov kev sim yog yaj nyob rau hauv fatty acid nyob rau hauv ib tug saturated lub xeev, uas yuav ua tau lub hom phiaj ntawm anticorrosion.
(2) Antioxidant, tiv thaiv -desiccant
Lwm qhov ua rau agglomerated blockages thiab siv lead ua crowns nyob rau hauv ballpoint cwj mem inks yog oxidation ntawm tooj dag thiab lub interface, thiab zus tau tej cov tooj liab thiab zinc compounds nyob rau hauv cov tshuaj. Antioxidants muaj cov khoom uas tuaj yeem nqus tau thiab nqus cov pa ib puag ncig, yog li lawv tuaj yeem tiv thaiv oxidation zoo. Kev sib xyaw ntawm cov tshuaj antioxidants thiab cov tshuaj tiv thaiv corrosion tuaj yeem tiv thaiv tau zoo dua los yog inhibit qhov corrosion ntawm tooj liab alloys. Kev sim qhia tias cov tshuaj antioxidants peb siv tau zoo. zoo. Hauv qhov kev sim, peb kuj tau siv cov tshuaj tiv thaiv- ziab khaub ncaws, uas nws lub luag haujlwm tseem ceeb yog los tiv thaiv oxidative ziab ntawm tus number case los yog tus cwj mem, kom tus number case thiab tus cwj mem kab muaj qhov pom kev zoo dua, thiab tib yam. lub sij hawm ncua lawv lub neej ua haujlwm thiab lub sijhawm khaws cia, thiab tuaj yeem txhim kho tus cwj mem ballpoint thaum siv. kev ua tau zoo, anti-desicant kuj yog ib qho antioxidant.
