Txhim kho kho cov ntawv laus-[N-Methylol Acrylamide 98%]
Daim ntawv, raws li lub ntsiab nqa ntawm daim ntawv kab lis kev cai relics, yog cov khoom muaj nqis ntawm tib neeg kev vam meej, inheriting thiab sau keeb kwm, kab lis kev cai thiab sab ntsuj plig kev vam meej ntawm lub teb chaws Suav.Nyob rau hauv xyoo tsis ntev los no, vim yog disrepair, natural aging, npauj-noj mildew, ib tug loj tus naj npawb ntawm daim ntawv tau tshwm sim loj acidification, aging, yellowing brittle thiab txawm comminuted phenomenon.Qhov kev tiv thaiv thiab kho cov ntaub ntawv kab lis kev cai relics nrog ntawv raws li cov cab kuj tau. them sai sai rau, tab sis kev kho dua tshiab ntawm daim ntawv los ntawm cov hauv paus hniav yog tsawg, nws yog ib qho nyuaj rau tiag tiag ncua nws cov kev pab cuam lub neej.Kev txuag thiab kev kho kom rov qab ua hauj lwm tsuas yog tsom rau cov txheej txheem deacidification, thiab kuj muaj ob peb txoj kev tshawb fawb txog kev txhawb zog.Cov txheej txheem kho qhov muaj zog uas twb muaj lawm tuaj yeem ua rau muaj kev puas tsuaj rau daim ntawv qauv, lossis hloov cov macroscopic morphology ntawm daim ntawv, lossis ua kom cov ntawv loj hlob tuaj, thiab cia siab rau ntawm phau ntawv, tsis tuaj yeem kho qhov loj.
Raws li cov txheej txheem kev laus ntawm daim ntawv thiab cov ntsiab lus tseem ceeb cuam tshuam rau lub zog ntawm daim ntawv, ua ke nrog cov xwm txheej tam sim no ntawm cov ntawv laus thiab cov kev xav tau rau kev kho dua tshiab ntawm daim ntawv kab lis kev cai, Ultrasonic atomization txoj kev siv los thauj cov atomized micron qib reinforcing tus neeg sawv cev rau nyob rau hauv daim ntawv ntawm ib tug tsawg ceev, kom paub meej tias daim ntawv maj mam thiab tag nrho nqus cov reinforcing tus neeg sawv cev, kom deb li deb tau kom tsis txhob deformation ntawm daim ntawv, thiab yuav siv tau rau loj reinforcement kho.N-hydroxymethylacrylamide raws li ib tug ntawv enhancer yog ib tug monomer nrog zoo solubility dej thiab tshuaj reactivity.Los ntawm lubkev sib txuastshuaj tiv thaiv ntawmN-Methylol Acrylamide thiab daim ntawv fiber ntau thiab nws tus kheej-crosslinking polymerization cov khoom ua rau qhov chaw ntawm daim ntawv fibers, txhim kho cov kev sib raug zoo ntawm cov ntawv fibers, thiab paub txog kev kho cov ntawv.
NMAtau siv nyob rau hauv lub zog kho ntawm electrostatic daim ntawv daim ntawv los ntawm ultrasonic atomization txoj kev, thiab lub zog ntawm atomization haum, enhancer concentration, atomization tus nqi thiab qhuav kub ntawm lub strengthening nyhuv ntawm electrostatic daim ntawv yog explored.Thiab cov kev hloov ntawm macroscopic morphology, microscopic nto cov qauv, cov ntsiab lus saum npoo av thiab cov pab pawg tshuaj hauv cov ntawv ua ntej thiab tom qab kev txhim kho.
Lub macroscopic morphology ntawm daim ntawv tsis hloov pauv loj tom qab kev kho kom zoo dua qub, uas tau lees paub tiasNMAtuaj yeem ua tiav qhov kev txhim kho kho dua tshiab ntawm daim ntawv yam tsis muaj kev puas tsuaj rau theem nrab, yog li nws tuaj yeem siv rau kev kho kom zoo dua qub ntawm cov ntawv qub qub xws li cov ntawv laus.Tom qab kev laus laus, cov khoom siv lub cev ntawm N-hydroxymethyl acrylamide txhim kho daim ntawv zoo dua li cov ntawv. Cov ntawv tsis kho, tshwj xeeb tshaj yog cov tensile Performance index thiab tearing Performance index muaj kev ruaj khov dua; Kev tsom xam ntawm infrared spectrum qhia tau hais tias cov yam ntxwv peaks ntawm hydrogen daim ntawv cog lus ruaj khov nyob rau hauv cov txheej txheem kev laus ntawm cov ntaub ntawv kho dua tshiab.Qhov sib ntxiv ntawm NMA tiv thaiv kev sib raug zoo ntawm cov ntawv fibers rau qee yam.
