Cov khoom siv raw ntawm daim ntawv tais tsuas yog kwv yees li 1% ntawm cov ntaub ntawv fiber ntau. Cov ntsiab lus noo noo ntawm daim ntawv ntub dej tom qab tsim yog txo mus rau 55% los ntawm kev siv tshuab nias, thiab cov dej noo ntawm cov ntawv tais tom qab sib sau yog siab li 65% -75%, uas ua rau nws nyuaj rau kev hla kev siv tshuab txo cov dej noo. Nyob rau hauv cov txheej txheem ntau lawm ntawm daim ntawv tais, txhua kilogram ntawm cov ntawv tiav yog qhuav. Txog 3.5-4.5 kg ntawm cov dej yuav tsum tau muab tshem tawm hauv cov txheej txheem, uas yog qhov tseem ceeb rau kev txhim kho kev ua kom qhuav, txo cov nqi tsim khoom, thiab txhim kho cov tais ntawv zoo.
Daim ntawv ntub dej nrog cov ntawv fiber ntau yog cov khoom ntxeem tau nrog cov qauv capillary sab hauv. Dej muaj nyob nruab nrab ntawm qhov chaw ntawm fiber ntau thiab qhov pores ntawm fiber ntau capillary.
Cov khoom siv hauv cov khoom siv hauv cov khoom ntim khoom feem ntau xav tau cov khoom zoo dynamic cushioning, thiab cov dej noo nyob rau hauv lawv tsis tuaj yeem ua tiav txhua yam.
Nws tuaj yeem raug tshem tawm los ntawm nias nws, thiab nws yuav tsum tau muab tshem tawm kom qhuav. Yog li ntawd, piv nrog cov txheej txheem ziab khaub ncaws, lub zog qhuav ntawm pulp molded khoom yog siab heev.
Ntawm qhov tod tes, huab cua kub ua hauj lwm los ua ib qho chaw cua sov los muab lub zog kom tshem tawm cov dej noo, thiab ntawm qhov tod tes, nws ua raws li cov khoom siv noo noo kom tshem tawm tsis tu ncua evaporating noo noo. Kev tshem tawm cov dej hauv qab daim ntawv ntub dej yog nyob ntawm qhov sib txawv ntawm cov dej sab hauv thiab sab nraud. Qhov thiaj li -hu ua internal diffusion yog hais txog cov txheej txheem tsiv teb tsaws ntawm cov dej noo los ntawm sab hauv mus rau sab nrauv nyob rau hauv cov ntaub ntawv ntub dej.
Sab nraud diffusion yog hais txog cov txheej txheem uas cov dej nqa tawm tom qab evaporating los ntawm qhov chaw. Qhov ziab ntawm daim ntawv txhawb nqa yog nyob ntawm qhov ceev ntawm cov dej diffuses 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 qho tib si saum toj no thiab kev ua kom qhuav ntawm cov ntawv tais khoom!
