Raws li cov txheej txheem ntau lawm, cov ntawv pallets tam sim no tuaj yeem ua rau ntau qhov ntau. Txawm li cas los xij, ziab yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv kev tsim cov ntawv pallets thiab tuav tus nqi ntau lawm. Yuav ua li cas txhawm rau txhim kho kev ziab kom qhuav ntawm daim ntawv tais thaum lub sijhawm tsim khoom?
Cov ntaub ntawv ntub dej ntim ntim
Cov khoom siv raw ntawm daim ntawv tais tsuas yog kwv yees li 1% daim ntawv fiber ntau. Los ntawm txoj kev siv tshuab nias, cov dej noo ntawm cov ntaub ntawv ntub dej yog txo mus rau 55%, thiab cov dej noo ntawm cov ntawv ntub dej yog siab li 65% -75%. Nws yog qhov nyuaj los txo cov dej noo los ntawm kev siv tshuab. Hauv cov txheej txheem tsim cov ntawv pallets, txog 3.5-4.5 kg ntawm dej yuav tsum tau muab tshem tawm rau txhua kilogram ntawm cov ntawv tiav tiav los ntawm kev ziab. Txawm hais tias nws yog los txo cov nqi tsim khoom lossis txhim kho cov ntawv tais zoo, kev txhim kho kev ziab kom qhuav yog qhov tseem ceeb heev!
Daim ntawv ntub dej nrog cov ntawv fiber ntau yog cov khoom ntxeem tau nrog cov qauv capillary sab hauv.
Cov dej muaj nyob nruab nrab ntawm qhov chaw ntawm cov fiber ntau thiab cov pores ntawm fiber ntau capillary. Cov khoom lag luam siv rau cov khoom ntim sab hauv feem ntau xav tau cov khoom zoo dynamic cushioning, thiab cov dej noo hauv lawv tsis tuaj yeem raug tshem tawm tag nrho los ntawm kev siv tshuab nias, tab sis yuav tsum tau muab tshem tawm los ntawm ziab. Yog li ntawd, piv nrog cov txheej txheem ziab ntawm daim ntawv, lub zog qhuav ntawm cov khoom siv molded yog siab heev.
Ntawm qhov tod tes, cua kub ua raws li qhov cua sov los muab lub zog tshem tawm cov dej noo; Ntawm qhov tod tes, nws ua raws li tus neeg nqa dej noo kom tshem tawm cov evaporating noo noo. Kev tshem tawm cov dej noo hauv daim ntawv ntub dej yog nyob ntawm qhov sib txawv ntawm cov dej noo sab hauv thiab sab nraud.
Qhov thiaj li -hu ua internal diffusion yog hais txog cov txheej txheem ntawm kev ya raws los ntawm sab hauv mus rau sab nrauv nyob rau hauv cov ntaub ntawv ntub dej, thaum lub diffusion sab nraud yog hais txog cov txheej txheem ntawm cov dej noo raug tshem tawm tom qab evaporating los ntawm nws qhov chaw. Lub ziab ceev ntawm daim ntawv tais nyob ntawm qhov ceev ntawm cov dej diffusion sab hauv thiab sab nraud thiab qhov sib npaug ntawm ob. Cov txheej txheem tsim nyog yuav tsum tau tsim nyob ib ncig ntawm ob qhov saum toj no thiab cov yam ntxwv ziab ntawm cov khoom pallet.
Raws li ib tug loj -scale ntawv pallet chaw tsim tshuaj paus nyob rau hauv Tuam Tshoj, Kunbaoda muaj mature paper pallet ntau lawm technology, muaj peev xwm paub loj-scale ntawv pallet ntau lawm ntawm tus nqi qis, thiab muaj peev xwm muab lub lag luam nrog siab - zoo thiab pheej yig daim ntawv pallet ntim.
