1, lub CF

Cellulose muab rho tawm ntawm ntoo los yog paj rwb uas muaj dab alkali (xws li sodium hydroxide), thiab mam li kho nrog Methyl chloride, methyl cellulose los ua. Thaum kawg cov khoom yog ib dawb ntau yam khoom kheej, soluble hauv dej txias tab sis soluble dej kub. Ntxiv mus thiab siv raws li cov nplaum rau methyl ether cellulose, kuj siv tau ua kab mob thooj, tus roj hmab ntuj thiab emulsion stabilizers.

Methyl cellulose yog zoo ntxhiab thiab cov mov dawb yuav daj-dawb granules los sis hmoov. Concentration 1% (w/v) cov PH nqi ntawm cov tshuaj ntawm 5.5--8.0, lub kaum sab xis ntawm repose yog li 40--50, nws yog hygroscopic. Expansion qeeb thiab proliferation txog methyl cellulose hauv dej txias, txoj kev ua ib pob tshab mus ncua kev kawm ntawv dawb, nplaum, gelatinous tshuaj dej cawv thiab nws cov viscosity tsub kom raws li cov concentration. Viscosity decreases nrog kub, rau qhov kub thiab txias mus txog li 50--degrees 60 Celsius daim ntawv ib gel. Reversible coagulation txheej txheem no, thaum nws tau txias dua ntawv tov khov.

Thaum lub wallpaper paste, cellulose yog ib yam ntawm cov siab dej ntsiab lus hauv cov universal muab tshuaj (li 97%), feem ntau, yog muaj ib qhov me me uas muaj cov hmoov dawb dawb. Thaum uas siv cov cellulose tov nrog dej txias heev, yuav tau siv tas nrog ntau hom ntaub ntawv sib zog, xws li: pa ya, nyom ntaub thiab txhob lo lo ntxhuav ntawv. Adhesion los cellulose yog feem ntau muaj rau cov neeg kho tshuab hom, tshwm sim tom qab smoothness siab, nws tsis hais txog cov neeg uas yuav tsum tau pib adhesion siab thiab tuav ntawm phab ntsa xim.

2, batter

Hmoov nplej uas feem ntau siv nyob rau hauv kev muab tshuaj wallpaper cov hmoov nplej, hauv cov huab cua tsis kub tsis txias zoo tagnrho. Decorating Center sells hnab hmoov nplej rau tus muag khoom, tus neeg siv cias dawb los yog txho dawb hmoov maj mam ua tus dej sov so thiab nrog ib lo me me los yog agitator lossi nplawm kom tsis txhob muaj hmoov nplej ntxiv tuaj. Ua ntej tshaj, hmoov nplej tso npe rau hauv ib lub hoobkas, ces quav thiab xyaw nrog lwm cov khoom xyaw. Tus batter yuav tau muab faib ua ntau ntau ntau, tab sis tej zaum koj yuav tsis nyob hauv cov lag luam cov ntaub ntawv tshuaj kho kom zoo nkauj

Lub hom phiaj kev muab tshuaj, cov ya raws qab lub cellulose hnav, li 90%--95%, ntxiv dej rau nws nyob ntawm qhov khoom. Thaum lub batter cov lug siv hauv adhesives, tiam sis lub xyoo pua 20th 50 's yas thiab siv cov xim rau pem taub hau nyob hauv lub 60 's, thaum kawg nplaum yas monopolized qhov lag luam lub teb chaws As Mes Lis Kas, ua rau cov batter siv cov poob. Tab sis, kuj tseem phab ntsa ntau yam khoom uas yuav siv lub batter lo rau ntawm phab ntsa, xws li cov tshuaj handprint thawj backing ntawv a dej siab, ntawv ntxeem tau, cov ntaub dub, ntawv, txhob lo lo ntxhuav, thiab ntau United Kingdom thaj wallpapers thiab li ntawd.

3, tos sib xyaw yas nplaum (nplaum)

Av nplaum nplaum yas tos tov yog qhia tshwj xeeb uas tsim rau ntawv yas phab ntsa ntaub ntawv, nws muaj av nplaum, dextrin, them ntawm cellulose, biocides thiab lwm additives. Muaj ib yam nplaum uas tos sib xyaw yas nplaum ntxiv Glycerin, tsim los rau machinery ntawv thiab khoom ua noj. Tos sib xyaw yas nplaum tsos kob los ziab rau grayish dawb, feem ntau yog qhwv rau hauv lub thoob yas ntawd loos 1 thiab 5 loos. Ntsiab kua nplaum, dej tsawg cov av nplaum premixed nplaum, li 40%--50%, feem ntau yog siv rau cov ntaub ntawv phab ntsa rau yav tom ntej adhesion. Phab ntsa khoom, xws li tej yas resins, lined nrog cov ntawv nyiaj thiab number case handprint ntawv hom.

pob tshab tos sib xyaw yas 4, nplaum

Pob tshab tos sib xyaw yas nplaum raws li ntuj polymers (xws li cov nplej thiab pob kws hmoov txhuv nplej siab) los yog polymers hluavtaws los cua kub los yog tshuaj txhais hais tias kom ua, yuav ua rau nws txoj saw ntev molecules rau hauv luv saw molecules. Sib ntxiv ntawm additives nyob rau hauv tus txheej txheem cellulose, lom ntawm tshuaj tua kab thiab mobile ceev dua, thiab hais txog. Hauv khw malls nyob rau hauv cov pob tshab nplaum rau siv los ntawm pawg thawj coj saib mus khaws plaster teev li "peelable", thiaj li yooj yim chais rau yav tom ntej redecorating. Pob tshab nplaum ntau yam heev, yuav siv rau ntawm phab ntsa ntaub ntawv, los ntawm lub teeb yuav luag hnyav yas khoom muaj txhua yam. Pob tshab nplaum rau wallpaper thiab muaj ntaub ntawv nrog nws sib txawv thaum nyiaj, nco ntsoov: nplaum pob tshab yuav mus taus wallpaper, kuj yuav tsis overcome lub phenomenon ntawm curling cuab kev. Ya raws kev kawm uas nplaum pob tshab yog li 60% - 70%.

5 、 VOV

Yas pem yas yog ib trademark cov khoom uas Roman decorating. VOV adhesives tsim los rau lub lag luam, yuavtsum yas phab ntsa khoom yuav siv ib yam tshiab yas phab ntsa txaus rau redecorating. VOV lub viscosity ntawm cov nplaum no muaj zog heev, tej zaum kuj yuav siv tau cov plahaum muab tshuaj txhuam taws kub viscosity. VOV, feem ntau incorrectly ib lo lus siv hauv qee zaus li yas nplaum.
