Nws yog tsuas yog los ntawm saum npoo kom nqus noo noo kom ua tiav qhov ziab lossis khi. Cov hmoov txhuv nplej siab hauv cov nplaum gelatinizes thiab nqus cov dej ntawm cov kab qhwv. Lub sijhawm sib raug zoo yog ob peb feeb mus rau ib feeb los yog li ntawd. Qhov noo noo yog maj mam nqus los ntawm cov cua hauv ib puag ncig thiab cov ntawv xov. Cov nplaum tsoos hluav taws xob no feem ntau siv rau hauv kev ua hauj lwm corrugated board cov kab ntau lawm, tuaj yeem tsim cov kev ua tiav zoo tam sim ntawd.
Yuav kom ua tiav txoj kev sib raug zoo txaus siab, yuav tsum tau ntxiv cov tshuaj cawv me ntsis ntxiv rau cov hmoov txhuv nplej siab thiab dej emulsion, uas muaj cov tshuaj pleev ua ntej-gelatinized. Txoj kev tshem tawm no tuaj yeem ncua cov hmoov nyoos rau hauv dej thiab tiv thaiv nws cov nag lossis daus; nce qhov siab ntxiv rau kev yooj yim raug coj los ntawm cov kua nplaum rau cov menyuam thiab ua daim ntawv lo ntawm cov tuab tsim nyog ntawm cov menyuam; kho cov viscosity kom daim ntawv fibers zoo tsim nyog thiab pib ua raws; Muaj ntau cov dej nyob ib puag ncig cov hmoov nplej molecules kom cov hmoov txhuv tuaj yeem nthuav mus rau qhov siab tshaj plaws thiab gelatinize ua tiav thaum rhaub; caustic sis dej qab zib yuav tsum tau muab ntxiv los kho thiab tswj qhov kub gelatinization ntawm cov hmoov txhuv nplej siab rau qhov qis tshaj.
Txhawm rau kom ua tiav cov txiaj ntsig kom txaus siab, borax yuav tsum tau ntxiv los ua kom cov hmoov nyoos nqus tau tag nrho cov dej muaj rau kev nqus thaum rhuab; los tsim cov viscosity kom zoo thiab tawv thaum cov hmoov txhuv nplej siab gelatinized; ua raws li qhov tsis tiv thaiv kom tsis txhob caustic dej qab zib ua kom qis dua Cov roj qis qis gelatinization, ib feem ntawm cov hmoov txhuv nplej siab hloov zuj zus tuaj.
