Kev ceev ntawm cov ntaub ntawv yas ntau lawm yog ib kauj ruam tseem ceeb hauv kev txiav txim siab cov khoom siv raws sij hawm. Cov hauv qab no yog cov ntsiab lus tseem ceeb cuam tshuam rau kev ceev ntawm cov ntawv yas ntau lawm kab:
1) Kev tsim khoom ib puag ncig: Phaj ntau lawm yuav tsum tau ua kom txias thiab tsim, yog li lub rooj cob qhia ntau lawm muaj qhov cua zoo. Qhov kub ntawm lub rooj cob qhia yuav tsum tsis txhob siab dhau, thiab dej kub yuav tsum tsis txhob siab dhau. Qhov chaw tsim khoom yuav cuam tshuam rau kev tsim khoom ceev thiab cov khoom zoo.
2) Kev ruaj ntseg ntawm cov khoom siv raw: Lub neej ua haujlwm ntawm daim hlau feem ntau yog li plaub mus rau tsib lub hlis. Cov phaj qub tuaj yeem siv tau thiab rov siv dua. Kev tsim tawm tshiab rau xyoo tom ntej tuaj yeem txo cov nqi raw khoom. Ntau tshaj 90% ntawm cov khoom siv raw ntawm lub rooj tsavxwm yog cov khoom siv rov ua dua tshiab ntawm cov laug cam qub. Feem ntau, granulation yuav tsum muaj tsawg kawg yog ob txheej ntawm 80 mesh lim thiab peb txheej ntawm 100 mesh lim. Kev huv ntawm cov khoom kuj tseem cuam tshuam rau kev ua haujlwm ceev. Self-granulation yuav txhim kho kev ruaj ntseg ntawm raw cov ntaub ntawv.
3) Lub tshuab ruaj khov: Cov cuab yeej qub feem ntau tsim tau 45-60m/min. Lub phaj thickness tsuas yog tswj tau manually, thiab qhov tseeb yog qhov nyuaj rau tswj. Rau cov tshuab high-speed, nws yog qhov nyuaj rau manually tswj cov thickness. Kev ntsuas tsis tu ncua thiab kev hloov kho ua rau muaj kev ua haujlwm ntawm cov neeg ua haujlwm thiab ua rau muaj kev pheej hmoo ntau lawm. Yog li, kuv xav kom koj ib puag ncig tus phooj ywg PP / PE daim ntawv ntau lawm kab.
