Yog tias daim ntawv kraft nyob rau hauv daim ntawv zeb thiab lub siab ntawm sab coated tsis txaus, cov fibers ntawm daim ntawv kraft nto yuav tsis ua raws li daim ntawv. Yog li ntawd, thaum peb ntim thiab luam ntawv thaum daim ntawv ntsib lub zog viscosity ntawm tus number case, yuav muaj teeb meem ntawm cov hmoov poob. Peb qhov kev pom zoo yog hmoov cov ntawv ua ntej ntim luam ntawv.
Thaum lub kraft ntawv ntim cov ntawv luam tawm, tus number case qib siab dhau lawm, tshwj xeeb tshaj yog thaum lub ntim puv puv yog luam tawm hauv cov xim dub, lub ntim thiab luam ntawv yuav twv yuav poob zoo li plua plav vim tias qib number case yog siab thiab viscosity siab. Cov txheej ntawm daim ntawv yog glued ua ke. Peb yuav tsum tau hloov nws mus rau daim pam, thiab tom qab ntawd mus rau daim ntawv thaub qab, yuav muaj cov cim kos, peb txoj kev daws teeb meem no yog siv cov tshuaj saum toj no, peb kuj tuaj yeem ntxiv qee tus cwj mem rau hauv daim ntawv thaub qab.
Nws tuaj yeem txo cov viscosity ntawm tus number case, yog li alleviating qhov teeb meem ntawm hmoov poob. Feem ntau, cov tuam txhab lag luam tshwj xeeb hauv kev muag cov ntawv kraft yuav muaj cov tshuaj no. Tus txiv neej no yuav tsum paub zoo tias yog tsis muaj cov tshuaj no, nws tuaj yeem mus tom khw yuav khoom.
Los ntawm txoj kev, tam sim no, ntau lub lag luam hauv tsev ntawm kraft ntawv yuav muaj qee qhov teeb meem nyuaj thaum ntim thiab luam ntawv. Peb tuaj yeem ntxuav cov hmoov av ntawm qhov chaw thaum lub sij hawm ntim thiab luam ntawv. Qee qhov teeb meem tshwm sim ntau heev vim tias qhov chaw muaj qee qhov hloov maj mam Koj tsis tuaj yeem pom cov plua plav, tab sis feem ntau nws tsis pom qhov "me me" uas ua rau muaj teeb meem. Yog li ntawd, thaum xaiv cov ntawv kraft, nws tseem ceeb heev uas yuav tsum tau them sai sai rau seb qhov chaw ntawm daim ntawv kraft puas huv.
