Daim ntawv kraft muaj zog heevFeem ntau raug xaiv thaum cov ntim khoom yuav tsum muaj sia nyob rau cov kab sau, kev nyuaj siab, kev pheej hmoo ntawm kev tawg, thiab kev thauj mus los ntev. Tab sis kev ua tau zoo tsis yog txiav txim siab los ntawm qhov tuab ib leeg. Daim ntawv kraft 50 GSM tej zaum yuav zoo tagnrho rau kev qhwv lub teeb, thaum cov qib kev lag luam saum toj no 150 GSM tej zaum yuav xav tau rau cov hnab lossis cov thawv xa khoom; ntawm cov ntsiab lus ntawd, cov khoom muaj zog tuaj yeem hloov pauv kev lag luam tag nrho. Cov nqi tensile, rhuav, tawg, thiab elongation qhia txog seb daim ntawv ua li cas hauv qab kev ntxhov siab tiag tiag, thaum cov dej noo thiab kev taw qhia xeem tuaj yeem hloov cov txiaj ntsig. Tsab xov xwm no piav qhia txog yuav ua li cas cov neeg yuav khoom tuaj yeem ntsuas qhov hnyav thiab lub zog ua ke los qhia cov ntawv kraft uas ruaj khov, tsim nyog, thiab haum rau lub hom phiaj.
Yuav Ua Li Cas Lub Hnyav thiab Lub Zog Txhais Tau Cov Ntawv Kraft Muaj Zog Siab
Thaum nrhiav cov ntaub ntawv ntim khoom uas tuaj yeem siv tau ntau,daim ntawv kraft muaj zog heevFeem ntau yog qhov kev xaiv zoo tshaj plaws. Ua los ntawm cov hmoov sulfate uas tsis tau dawb, daim ntawv no siv tau ntev hauv kev lag luam thiab kev lag luam uas nyuaj heev. Yuav kom ua tau zoo tshaj plaws, cov neeg yuav khoom yuav tsum nkag siab txog qhov hnyav thiab lub zog ntawm lub cev ua haujlwm ua ke li cas.
Nws tsis yog hais txog kev xaiv daim ntawv tuab tshaj plaws ntawm lub txee xwb; nws yog hais txog kev nrhiav qhov sib npaug zoo meej rau ib qho kev siv tshwj xeeb. Los ntawm kev nkag siab txog kev sib raug zoo ntawm qhov hnyav ntawm daim ntawv thiab kev tiv taus lub zog, cov neeg yuav khoom tuaj yeem txiav txim siab tau zoo dua.
Qhov Hnyav Qhia Li Cas Rau Cov Neeg Yuav Khoom
Qhov hnyav pib, ntsuas hauv grams ib square meter (GSM), yog qhov pib txheem, muab ib daim duab sai ntawmqhov hnyav thiab tuab ntawm daim ntawvPiv txwv li, sib duakraft ntawv yobzaum li ntawm 50 GSM, ua rau lawv zoo tagnrho rau kev qhwv yooj yim, sau qhov khoob, lossis hnab muag khoom. Ntawm qhov tod tes, cov qib kev lag luam hnyav feem ntau tshaj 150 GSM los muab qhov loj thiab lub peev xwm thauj khoom uas xav tau rau cov hnab ntau phab ntsa thiab cov thawv xa khoom.
Txawm li cas los xij, kev xav tias qhov hnyav siab dua yuav ua rau kev ua tau zoo dua yog qhov yuam kev ntau. Qhov hnyav qhia txog qhov ntau ntawm cov khoom siv tab sis tsis piav qhia tag nrho tias cov fibers pulp sib txuas zoo npaum li cas. Kev cia siab rau qhov hnyav ib leeg tuaj yeem ua rau ntim khoom ntau dhau thiab cov nqi khoom siv tsis tsim nyog.
Cov Khoom Muaj Zog Twg Tseem Ceeb Tshaj Plaws
Txawm hais tias qhov hnyav ntawm daim ntawv ua rau daim ntawv loj, tab sis lub zog tshwj xeeb qhia tias daim ntawv yuav ua li cas thaum muaj kev ntxhov siab. Lub zog tensile ntsuas lub zog rub uas daim ntawv tuaj yeem tiv taus ua ntej tawg, uas yog qhov tseem ceeb rau kev ua kom cov kab ntim khoom ceev ceev khiav tau zoo yam tsis muaj kev tawg ntawm daim ntaub.
Kev tiv thaiv kev rhuav thiab tawg kuj tseem ceeb ib yam, tshwj xeeb tshaj yog thaum ntim cov khoom hnyav lossis cov khoom siv uas yuav ua rau lub hnab tawg. Piv txwv li, kev ntseeg tauntawv hnab lag luamxav tau qhov ntsuas qhov tawg uas tau teem tseg kom tiv thaiv kev tawg thaum lub sijhawm thauj mus los tsis zoo. Tsis tas li ntawd xwb, cov khoom zoo elongation tso cai rau daim ntawv kom ncab me ntsis yam tsis muaj kev tawg, nqus cov kev poob siab sai sai yog tias lub pallet poob lossis txav mus los. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov ntsuas lub zog no tsis yog cov khoom siv ruaj khov; lawv sib txawv ntau raws li cov dej noo, kev coj mus kuaj (kev coj mus kuaj tshuab piv rau kev coj mus kuaj hla), thiab kev mob ib puag ncig.
Yuav Ua Li Cas Piv Qhov Hnyav, Lub Zog, thiab Tus Nqi
Nrhiav qhov chaw zoo tshaj plaws ntawm kev ua tau zoo thiab nyiaj txiag yuav tsum tau saib xyuas qhov hnyav, lub zog, thiab tus nqi. Vim tias daim ntawv feem ntau raug nqi raws li qhov hnyav, tsuas yog xaj GSM hnyav dua los txhim kho kev tiv thaiv kev rhuav tshem yuav ua rau cov khoom siv thiab cov nqi xa khoom kim dua.
Qhov tseem ceeb yog muab cov yam no sib piv ua ke los txhim kho koj txoj kev ntim khoom. Feem ntau, kev them nqi siab rau kev tsim kho siab heev ua rau txuag tau ntau ntawm kev siv cov khoom siv tag nrho.
Siv Cov Lus Sib Piv los Qhia Txog Kev Sib Hloov
Yuav kom pom tias cov kev hloov pauv no sib cuam tshuam li cas, kev kos duab qhia lawv yuav pab tau. Daim ntawv piv txwv hauv qab no qhia txog vim li cas lub teeb,daim ntawv tsim kho zoo heevtej zaum yuav ua tau zoo dua li lwm txoj hauv kev uas hnyav dua ntawm lub Hoobkas.
| Qib ntawv | Qhov Hnyav Pib (GSM) | Kev Ntsuas Tensile (Nm / g) | Cov Ntsis Tsim Kua Muag (mN·m²/g) | Tus nqi sib piv rau ib Ton |
|---|---|---|---|---|
| Txheem Kraft | 120 | 65 | 9.0 | Kab pib (1.0x) |
| Kraft Muaj Zog Siab | 90 | 85 | 12.5 | 1.2x |
| Kev Lag Luam Hnyav | 150 | 70 | 10.5 | 1.1x |
Cov lej piv txwv no qhia tau tias cov kev xaiv uas tau tsim kho zoo heev muab cov ntsuas tensile thiab tear zoo dua txawm tias qhov hnyav qis dua. Tus nqi them rov qab 1.2x rau cov qauv muaj zog siab feem ntau yog tsav los ntawm cov khoom sib xyaw tshwj xeeb, lub zog ua kom zoo dua, thiab cov tshuaj ntxiv. Cov ntaub ntawv no ua rau nws yooj yim dua los pom cov kev sib haum xeeb uas tau ua thaum xaiv qib.
Thaum Lub Zog Tensile Siab Dua Tsim Nyog Tus Nqi
Tej zaum nws yuav zoo li tsis yog qhov yuav tsum tau them 20% ntxiv rau cov khoom siv sib dua, tab sis lub zog tensile siab dua feem ntau ua rau tus nqi pib ua ntej. Thaum nrhiav kev ua haujlwm siabkraft ntawv jumbo yob, cov neeg yuav khoom feem ntau tuaj yeem txo qhov hnyav ntawm lawv cov ntim khoom yam tsis muaj kev cuam tshuam kev ruaj khov.
Piv txwv li, kev txo qis ntawm daim ntawv 120 GSM tus qauv mus rau 90 GSM lub zog siab ua rau tag nrho cov tonnage uas xav tau los tsim tib lub hnab. Txoj kev ua kom lub teeb no pab them tus nqi siab dua ib tonne, txo qhov hnyav ntawm kev xa khoom tawm, txo qhov chaw cia khoom hauv tsev rau khoom, thiab txo qhov cuam tshuam rau ib puag ncig.
Yuav Ua Li Cas Qhia Txog Daim Ntawv Kraft Rau Kev Ntim Khoom
Kev qhia meej txog qib ntawv zoo yuav tsum tau saib ze ze seb cov ntim khoom yuav kav ntev npaum li cas, txij li ntawm lub Hoobkas mus rau tus neeg siv kawg. Txawm yog nrhiav cov khoom siv rau cov hnab khw muag khoom lossiscov hnab looj tes ua haujlwm hnyav, kev tau txais cov lus qhia kom raug ua kom muaj kev tiv thaiv khoom yam tsis tas siv nyiaj ntau.
Cov Kauj Ruam Ua Tau Zoo Rau Kev Sib Piv Qib Ntawv Rau Cov Qauv Siv
Txuas cov khoom siv kho tshuab ntawm daim ntawv ncaj qha rau qhov kev siv tshwj xeeb. Yog tias ntim 25 kg ntawm cov cement lossis cov hmoov tshuaj zoo, cov hnab ntau phab ntsa yuav tsum muaj qhov porosity siab thiab ncab. Qhov no tso cai rau cov cua uas raug kaw kom tawm thaum lub sijhawm sau sai yam tsis ua rau lub hnab tawg ntawm kab ntau lawm.
Los yog, yog tias sivkraft ntim ntawvUa ib txheej sib txuas rau cov khoom hlau ntse lossis cov tshuab hnyav, kev tiv thaiv kev tho thiab kev ruaj khov ntawm qhov ntev ua qhov tseem ceeb tshaj plaws. Cov yam ntxwv ib puag ncig kuj yuav tsum tau xav txog; yog tias cov khoom yuav nyob hauv qhov chaw cia khoom ntub lossis ntsib kev thauj mus los sab nraum zoov, kev qhia meej txog kev kho kom muaj zog ntub pab tiv thaiv daim ntawv kom tsis txhob poob nws cov khoom siv kho tshuab. Txawm li cas los xij, cov neeg yuav khoom yuav tsum paub tias cov khoom ntxiv rau lub zog ntub (xws li PAE resins) hloov pauv daim ntawv rov ua dua tshiab thiab kev ua raws li txoj cai, ua qhov no yog qhov tseem ceeb rau kev yuav khoom.
Cov Pab Pawg Yuav Khoom Yuav Ua Li Cas Thiaj Txiav Txim Siab Zaum Kawg
Cov pab pawg yuav khoom yuav tsum sib koom ua ke cov kev xav tau kev txawj ntse no nrog rau qhov tseeb ntawm cov khoom siv txhua hnub. Thaum ua tiav qhov kev txiav txim siab, nws yog ib qho tseem ceeb uas yuav tsum soj ntsuam qhov tsawg kawg nkaus ntawm kev txiav txim (MOQs), uas feem ntau yog txij li 5 txog 10 metric tons rau cov qauv zog uas tsim tshwj xeeb.
Cov neeg yuav khoom kuj yuav tsum soj ntsuam qhov sib xws ntawm tus neeg muag khoom los ntawm kev thov cov ntaub ntawv kuaj thoob plaws ntau qhov kev tsim khoom kom ntseeg tau tias cov qauv zoo txhim khu kev qha. Thaum kawg, kev sib npaug ntawm qhov hnyav, cov ntsuas zog, thiab cov tsav tsheb tsim kom muaj lub moj khaum kev txiav txim siab meej uas tiv thaiv kev ntim khoom ntau dhau thaum tseem ua kom ruaj khov rau cov khoom xa tuaj.
