Xim erasers tau siv dav los ntawm cov tub ntxhais kawm, cov neeg ua haujlwm hauv chaw ua haujlwm thiab cov neeg nyiam kos duab. Tsis zoo li cov khoom siv niaj hnub, cov khoom siv xim yuav tsum muab kev ua haujlwm zoo ib yam thaum tswj cov xim sib xws, cov duab, qhov ntev thiab qhov zoo. Txawm hais tias tus lwv yuav tshwm sim los ua ib qho khoom siv yooj yim, nws cov khoom tsim muaj ntau theem ua tib zoo tswj, nrog rau kev npaj cov khoom, xim tsim, kev sib xyaw, sib sau, ua tiav thiab tshuaj xyuas zoo.
Kev npaj cov khoom yog lub hauv paus ntawm kev tsim khoom. Cov neeg tsim khoom xaiv cov khoom siv roj hmab tsim nyog los yog elastomeric raws li daim ntawv thov thiab npaj cov khoom xyaw uas yuav tsum tau ua raws li cov qauv tsim. Qhov sib txawv ntawm cov ntaub ntawv sib txawv tuaj yeem cuam tshuam rau hardness, elasticity, tshem tawm kev ua tau zoo thiab kev ua haujlwm, yog li cov khoom tuaj yuav tsum tau kuaj xyuas thiab npaj kom zoo ua ntej pib tsim khoom.
Xim formulation yog ib feem ntawm cov xim pleev xim tsim. Lub hom phiaj xim yog txiav txim raws li cov khoom tsim, tom qab uas haum colorants yog incorporated rau hauv lub hauv paus khoom. Kev sib xyaw ua kom zoo thiab sib xws yog qhov tseem ceeb kom ua tiav qhov pom zoo thoob plaws hauv cov khoom tiav. Thaum ntau cov xim raug tsim, cov txheej txheem ntau lawm yuav tsum tau ua tib zoo tswj kom tsis txhob muaj xim tsis zoo thiab sib txawv.
Cov khoom xyaw npaj ces txav mus rau hauv lub compounding thiab processing theem. Cov khoom sib txawv yog sib xyaw kom huv si kom cov xim thiab lwm cov khoom xyaw raug faib kom sib npaug thoob plaws hauv cov khoom. Cov txheej txheem ua haujlwm yuav tsum tau tswj kom zoo kom ua tiav qhov sib xyaw nrog cov yam ntxwv ruaj khov thiab tsim nyog rau kev tsim khoom rau theem tom ntej.
Cov khoom siv ces nkag mus rau theem tsim. Raws li qhov xav tau qhov ntev thiab cov khoom geometry, cov cuab yeej tsim nyog yog siv los ua cov khoom siv rau hauv daim ntawv xav tau. Cov cuab yeej raug thiab cov ntsiab lus ntawm qhov chaw tuaj yeem cuam tshuam ncaj qha rau cov tsos ntawm cov lwv tiav, ua pwm tsim ib qho tseem ceeb xav txog. Rau cov khoom uas muaj cov duab tshwj xeeb, cov qauv lossis cov qauv zoo nkauj, cov cuab yeej yuav tsum tau tsim los tsim cov ntsiab lus kom raug.
Tom qab kev tsim, cov khoom siv trimming thiab tiav. Cov khoom me me ntawm cov khoom siv ntau dhau tuaj yeem nyob ib puag ncig ntawm cov npoo tom qab molding thiab yuav tsum tau muab tshem tawm los tsim kom zoo nkauj thiab zoo ib yam. Qee cov khoom lag luam kuj tseem tuaj yeem tau txais cov duab kos duab, ntawv nyeem lossis cov khoom lag luam los txhim kho lawv qhov pom kev tsim.
Kev tshuaj xyuas zoo yog ib kauj ruam tseem ceeb ua ntej ntim. Cov kws tshuaj ntsuam xyuas tuaj yeem tshawb xyuas cov xim sib xws, qhov ntev, cov duab, qhov chaw nyob thiab qhov yooj yim tshem tawm kev ua haujlwm. Rau siab - ntim ntau lawm, sampling kev soj ntsuam thiab kev tswj cov txheej txheem tuaj yeem pab tswj kev sib xws ntawm cov khoom sib txawv.
Thaum cov khoom dhau los ntawm kev tshuaj xyuas, cov txheej txheem ua tiav tuaj yeem ntim thiab npaj rau kev cia lossis xa khoom. Zuag qhia tag nrho, coloured eraser manufacturing muaj kev sib koom tes tswj cov khoom, xim formulation, tooling, forming thiab zoo tswj. Ib qho zoo- cov txheej txheem tsim khoom tswj tau pab txhim kho cov khoom sib xws thiab kev ntseeg siab thaum txhawb nqa ntau yam kev xav tau ntawm cov neeg siv khoom siv niaj hnub no.
