Nrog kev txhawb nqa ntawm lub teb chaws kev paub txog ib puag ncig, ntawm ib sab tes, tag nrho lub zej zog txhawb nqa kev tsim khoom huv thiab xav kom tag nrho lub neej ntawm cov khoom yuav tsum paub txog kev txuag hluav taws xob, txo kev siv, txo kev ua qias tuaj, thiab kev ua haujlwm zoo; ntawm qhov tod tes, txhawm rau kom ua tau raws li qhov xav tau ntawm kev ntim khoom ntsuab, cov khoom ntim khoom yuav tsum muaj kev nyab xeeb thiab huv si, muaj kev hloov pauv zoo rau kev tiv thaiv ib puag ncig, thiab tuaj yeem txuag cov peev txheej.
Kev tsim thiab siv cov khob ntawv yog ua raws li txoj cai tiv thaiv ib puag ncig hauv tebchaws. Kev hloov cov khob yas pov tseg nrog cov khob ntawv txo qhov "kev ua qias tuaj dawb". Qhov yooj yim, kev huv huv thiab tus nqi qis ntawm cov khob ntawv yog qhov tseem ceeb rau kev hloov lwm yam khoom siv kom nyob hauv kev lag luam dav dav. Cov khob ntawv raug muab faib ua cov khob dej txias thiab cov khob dej kub raws li lawv lub hom phiaj. Ntxiv nrog rau kev ua kom tau raws li qhov xav tau ntawm lawv cov ntim khoom thiab kev ua haujlwm, cov ntaub ntawv ntawm cov khob ntawv kuj yuav tsum ua tau raws li lawv qhov kev hloov pauv luam ntawv. Ntawm ntau yam hauv kev siv tshuab luam ntawv, cov xwm txheej rau kev kaw cua sov ntawm kev ua khob ntawv kuj yuav tsum tau ua tiav.
Cov khoom siv ntawm khob ntawv
Cov txheej txheem tsim cov khob haus dej txias yog luam tawm ncaj qha, txiav tuag, pwm, thiab laminating ob sab los ntawm daim ntawv hauv qab ntawm lub khob ntawv. Cov txheej txheem tsim cov khob haus dej kub yog los ntawm daim ntawv hauv qab ntawm lub khob ntawv mus rau daim ntawv khob ntawv, luam ntawv, txiav tuag, thiab ua cov txheej txheem tsim.
Cov ntawv sau ua ntawv khob
Cov ntawv hauv paus ntawm lub khob ntawv yog tsim los ntawm cov nroj tsuag fibers. Cov txheej txheem ntau lawm feem ntau yog siv cov ntoo coniferous, ntoo nplooj dav thiab lwm cov nroj tsuag fibers kom dhau los ntawm lub rooj tsavxwm pulp tom qab pulping, dredge, zom cov pulp, ntxiv cov khoom siv tshuaj, tshuaj ntsuam, thiab theej lub tshuab ntawv.
Cov khoom sib xyaw ntawm daim ntawv khob ntawv
Daim ntawv khob ntawv yog ua los ntawm daim ntawv hauv qab khob ntawv thiab cov yas cob uas raug extruded thiab sib xyaw ua ke. Polyethylene resin (PE) feem ntau yog siv rau cov yas cob. Daim ntawv hauv qab khob ntawv ua los ntawm daim ntawv khob PE ib daim lossis ob daim ntawv khob PE tom qab lamination zaj duab xis PE ib sab lossis ob sab PE zaj duab xis. PE muaj nws tus kheej tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis muaj ntxhiab; cov khoom zoo huv si; cov khoom tshuaj ruaj khov; cov khoom sib npaug ntawm lub cev thiab lub tshuab, tiv taus txias zoo; tiv taus dej, tiv taus noo noo thiab qee yam oxygen, tiv taus roj; kev ua haujlwm molding zoo heev thiab kev ua haujlwm zoo sealing kub thiab lwm yam zoo. PE muaj peev xwm tsim khoom loj, qhov chaw yooj yim thiab tus nqi qis, tab sis nws tsis haum rau kev ua noj kub siab. Yog tias khob ntawv muaj cov kev cai tshwj xeeb, cov yas cob uas muaj kev ua haujlwm sib xws raug xaiv rau lamination.
Cov kev cai rau cov khob ntawv substrate
Cov kev xav tau ntawm cov ntawv khob hauv qab ntawv
Daim ntawv hauv paus ntawm lub khob ntawv luam tawm ncaj qha yuav tsum muaj qee qhov zog ntawm qhov chaw (tus nqi pas nrig ciab ≥14A) kom tiv thaiv cov plaub hau poob thiab hmoov poob thaum luam ntawv; tib lub sijhawm, nws yuav tsum muaj qhov zoo ntawm qhov chaw kom tau raws li qhov sib xws ntawm cov ntawv luam tawm.
