Txhim kho kev kho ntawm cov ntawv laus- [N-methylol acrylamide 98%]
Daim ntawv, raws li cov cab kuj tseem ceeb ntawm kev ua kab lis kev cai lij choj ntawm tib neeg, yog qhov muaj peev xwm ua neeg tau kev vam meej ntawm tib neeg, tau txais keeb kwm, kab lis kev cai thiab kev coj ua ntawm sab ntsuj plig.Nyob rau hauv xyoo tsis ntev los no, vim muaj kev cuam tshuam txog kev txom nyem, cov laus laus, muaj kev tiv thaiv loj thiab muaj kev tiv thaiv kev cai lij choj thiab kev kho kom haum rau cov ntawv raws li cov cab kuj Them sai sai rau, tab sis kev kho kom rov qab los ntawm cov hauv paus yog tsawg dua, nws yog qhov ua haujlwm tseem ceeb rau kev ua haujlwm ntawm Deacidification, thiab ob peb txoj kev kawm ntawm kev txhawb nqa. Cov qauv kev pab kho cov txheej txheem uas twb muaj lawm tuaj yeem ua rau kev puas tsuaj rau cov qauv ntawv, lossis hloov kho cov ntawv me me, thiab cia siab tias yuav siv tau kev txhawb nqa huab hwm coj.
Raws li kev laus kev ua haujlwm ntawm daim ntawv thiab cov ntsiab lus tseem ceeb cuam tshuam rau lub zog ntawm cov ntawv, ua ke nrog cov kev ua kom muaj atomized ntxiv rau sab hauv ntawm daim ntawv ntawm lub nrawm dua, kom ntseeg tau tias daim ntawv maj mam ua kom muaj kev txhawb nqa kev tiv thaiv kev txhim kho.n-hydroxymethylacrylamide raws li a cov ntawv enhancer yog ib tug monomer nrog cov dej ua kom zoo thiab tshuaj lom neeg cuam tshuam.throffe tuscross-txuascov tshuaj tiv thaiv nruab nrab ntawmN-methylol acrylamide Thiab cov ntawv fiber ntau thiab nws tus kheej-crosslink cov khoom ntim sau cov ntawv ntawm cov ntawv sib koom tes, txhim kho cov ntawv sib khi ua ke, thiab paub txog kev kho cov ntawv.
NmAtau siv rau hauv cov electrostating daim ntawv los ntawm kev ua kom muaj zog, txhim kho cov kev nqus hluav taws xob tau tshawb xyuas. Cov qauv, cov ntsiab lus saum npoo av thiab cov pab pawg sab hauv ntawm cov ntawv ua ntej thiab tom qab qhov cuab lub zog.
Macroscopic morphology ntawm daim ntawv tsis tau hloov pauv ntau tom qab kev kho kom zoo dua qub, uas tau txheeb xyuas qhov ntawdNmAyuav tau paub meej qhov txhim kho cov ntawv kho kom muaj kev puas tsuaj qib siab xws li kev laus dua, yog li nws tuaj yeem siv rau kev laus cov ntawv qub xws li cov ntawv qub ancient, yog li nws tuaj yeem siv rau cov ntawv qub qub zoo xws li cov ntawv qub qub ntawm N-Hydroxymethyl acrylamide zoo dua li cov Tsis tau kho daim ntawv, tshwj xeeb tshaj yog cov ntsuas tensile thiab cov khoom siv tawv muaj zog tshaj plaws hauv cov txheej txheem hydrogen actab yog qhov ruaj khov nyob rau hauv cov txheej txheem kev laus ntawm cov txheej txheem kev laus ntawm cov txheej txheem ntawm cov txheej txheem kev siv nyiaj txiag. Qhov kev sib txuas ntawm NMA tiv thaiv cov nyiaj sib khi ntawm cov ntawv sau rau qee yam.
