Cov laj thawj ntawm cov xim luam tawm saum npoo yog cov ntawv tuab, cov kev coj ntawm cov ntuab ntab ntawm cov ntawv, cov ntsiab lus tsis haum ntawm cov nplaum, ntau npaum li cov kua nplaum siv rau ntawm qhov siab corrugated, lub siab tom qab ua pauj, thiab ya raws cov ntsiab lus ntawm duab los qhia.
Qhov teeb meem ntawm dewy hws tuaj yeem tswj tau los ntawm:
Kev tsim nyog txhim kho cov lej ntawm cov xim luam ntawv, thiab siv cov yam ntxwv ntawm kab rov tav loj dua li cov ntsia pom ntsug loj dua tom qab nqus cov dej los ntawm daim ntawv qub, thiab hla-haum cov ntsug txhob lo lo ntxhuav ntawm cov xim luam ntawv rau hauv "ntxiv" hom.
Txhim kho cov ntsiab lus ntawm cov nplaum, txo cov dej noo hauv cov nplaum, thiab kho qhov sib txawv ntawm cov nplaum rau cov menyuam (lossis tshuab ua kua nplaum) thiab lub tshuab ua kom siab, nyob rau hauv qhov kev ua kom paub tseeb tias cov xim luam ntawv thiab corrugated ua ke kom zoo, kom tsawg tus nqi ntawm cov kua nplaum ntawm lub crucible.
Tom qab cov nplaim qhuav kev kho mob, cov dej tswj tau li ntawm 9 txog 2% kom cov fiber ntau ntawm cov xim luam ntawv txiav, tuaj yeem txo lub lwg.
Cov nplaum ntawm cov nplaim nplaum zoo li qhib lossis corrugated cev qhuav dej nplaum tam sim no feem ntau siv nrog oxidizing cov hmoov txhuv nplaum nplaum, yog tias lub ntsej muag oxidation nplaum rau hauv cov txheej txheem npaj cov hmoov txhuv nplej siab tsis txaus, los yog cov hmoov txhuv nplej siab oxidation ntau dhau, yuav ua rau muaj qhov zoo ntawm cov nplaum tsis ruaj khov, yog li tshwm sim qhib kua nplaum. Tsis tas li, yog tias cov kua nplaum lo tsawg dhau, uas ua rau cov kua nplaum lo tsawg dhau ntawm qhov ncab ntawm qhov corrugated yuav tshwm sim qhib cov kua nplaum.
Yog tias nws nrog cov kua nplaum ua kua nplaum rau lub veneer, nws txheej ntawm cov nplais ntawv lossis cov ntawv saum npoo yog tsis tiaj tus kheej yuav tseem ua rau txoj kev qhib kua nplaum. Ntawm lub veneer mus rau lub veneer, lossis nrog tes lo kua nplaum veneer, yog tias tus nqi ntawm cov kua nplaum thov rau lub txheej txheem corrugated yog qhov loj heev, yooj yim ua rau cov kua nplaum ua kua nplaum tom qab ntau muag, tom qab ntawv saum npoo ntawv haum yuav tshwm sim corrugated cev qhuav dej Cov. Tsis tas li ntawd, ntau npaum li cas ntawm kua nplaum yog qhov loj heev tsis tsuas yog pov tseg kua nplaum, tab sis kuj ua rau cov khoom lag luam tom qab lub veneer yog qhov nyuaj kom qhuav. Yog li, qhov ntau ntawm cov ntawv thov gel yuav tsum raug tswj hwm nruj me ntsis.
