Daim ntawv ci li cas?

Kev ua cov ntawv ci yog qhov muag heev, ntau cov txheej txheem tsim los tsim cov khoom lag luam nrog cov khoom siv tshwj xeeb. Ntawm no yog ib qho kev ntsuam xyuas qhov tob ntawm cov txheej txheem ci ntawv:
1. Raw khoom xaiv
Daim ntawv ci feem ntau yog tsim los ntawm cov khoom siv ntuj xws li ntoo pulp, paj rwb fiber, thiab cellulose. Kev xaiv ntawm cov ntaub ntawv raw yog qhov tseem ceeb rau qhov zoo, kev nyab xeeb thiab kev ua haujlwm ntawm daim ntawv ci. Ntoo pulp yog ib qho kev xaiv vim nws muaj ntau thiab yooj yim rau txheej txheem. Nyob rau tib lub sijhawm, txhawm rau ua kom cov khoom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig, cov khoom siv raw xaiv yuav tsum ua raws li cov qauv thiab cov kev cai.
2. Manufacturing pulp
stirring thiab pulping: Ntxiv cov khoom raw xaiv rau hauv dej thiab do kom tsim tau slurry. Cov txheej txheem no yuav tsum tau siv lub tshuab pulp kws tshaj lij, uas ua rau cov khoom siv tshuaj lom neeg los yog tshuaj lom neeg thiab disperses lawv hauv dej los tsim ib lub pulp.
Kev kho purification: Yuav kom tshem tawm cov impurities thiab teeb meem tshuaj nyob rau hauv lub pulp, purification kev kho mob yuav tsum tau. Qhov no suav nrog cov kauj ruam xws li pom thiab ntxuav kom huv si thiab zoo ntawm cov tawv nqaij.

3. Ua ntawv
Kev sib sau thiab nias: Ncuav lub pulp rau hauv lub tshuab ntawv thiab lim nws los ntawm lub mesh los ua ib daim ntawv ntub dej. Daim ntawv ntub dej yog tom qab ntawd dewatered los ntawm cov xovxwm kom tshem tawm cov dej noo ntau dhau thiab txhim kho qhov qhuav thiab lub zog ntawm daim ntawv.
Qhuav thiab coiling: Cov ntawv xovxwm ntub dej nkag mus rau ntu kom qhuav rau kev kho kom qhuav. Thaum lub sij hawm ziab, cov dej ntawm daim ntawv maj mam evaporates, tsim cov ntawv qhuav nrog qee lub zog thiab yoog raws. Thaum kawg, daim ntawv qhuav yog dov mus rau hauv ib lub yob kom yooj yim tom qab ua thiab siv.
4. Ua rau hauv daim ntawv ci
Txheej kev kho mob: Yuav kom muab cov ntawv ci tshwj xeeb ua haujlwm (xws li kev tiv thaiv kev tiv thaiv, kub kub ua haujlwm, thiab lwm yam), nws yuav tsum tau coated. Cov txheej txheem siv feem ntau muaj xws li cov txheej tsis lo, cov roj pov thawj, thiab lwm yam. Cov txheej txheem no tuaj yeem sib npaug ntawm cov ntawv thiab tsim cov yeeb yaj kiab tiv thaiv.
Txiav thiab ntim: Cov ntawv coated yog txiav rau hauv qhov xav tau loj thiab cov duab thiab tom qab ntawd ua tiav rau ntim. Cov khoom ntim yuav tsum muaj cov khoom sib khi zoo thiab cov khoom pov thawj los xyuas kom meej tias daim ntawv ci tsis muaj kab mob thiab puas thaum lub sij hawm khaws cia thiab kev thauj mus los.

5. Kev soj ntsuam zoo thiab ntawv pov thawj
Thaum lub sij hawm tsim khoom, daim ntawv ci yuav tsum tau ua raws li kev soj ntsuam nruj thiab cov txheej txheem ntawv pov thawj. Qhov no suav nrog kev sim cov ntawv lub cev (xws li tuab, lub zog, nqus dej, thiab lwm yam), cov khoom siv tshuaj lom neeg (xws li cov ntsiab lus tsis zoo, thiab lwm yam), thiab cov khoom siv ua haujlwm (xws li kev tiv thaiv, kev kub siab, thiab lwm yam. ). Tsuas yog daim ntawv ci uas tau dhau qhov kev tshuaj ntsuam xyuas zoo thiab ua raws li cov qauv thiab cov kev cai tseem ceeb tuaj yeem tso cai tawm hauv lub Hoobkas mus muag.
Cov ntsiab lus
Cov txheej txheem ntau lawm ntawm daim ntawv ci yog txheej txheem nyuaj thiab muag heev, nrog rau ntau yam kev sib txuas xws li kev xaiv cov khoom siv raw, kev tsim cov ntaub ntawv, cov ntawv tsim, ua rau hauv daim ntawv ci, thiab kev kuaj xyuas zoo thiab ntawv pov thawj. Txhua qhov txuas yog qhov tseem ceeb, thiab txhua qhov kev tsis saib xyuas yuav cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm daim ntawv ci. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj qhov zoo thiab cov txheej txheem tsis sib xws ntawm txhua qhov txuas thaum lub sij hawm tsim cov txheej txheem los xyuas kom meej cov khoom zoo, muaj kev nyab xeeb thiab txhim khu kev qha ci ntawv.
