Mokhoa ona o ka khetha selulose e qhibilihang ka potlako, 'me e na le tšoaetso ea hlobo.Molemo oa mokhoa ona ke ho ba le ho feto-fetoha ho hoholo, ho ka kopanya pente ea emulsion ka ho toba, ho etsa mokhoa o ts'oanang le ①–④ mohato o ts'oanang.
3, ka motoho bakeng sa tšebeliso
Kaha li-solvents ke li-solvents tse futsanehileng (tse sa tsitsang) bakeng sa hydroxyethyl, li ka sebelisoa ho lokisa motoho.Li-solvents tse sebelisoang ka ho fetesisa ke li-organic liquids tse entsoeng ka pente ea latex, joalo ka ethylene glycol, propylene glycol le li-agent tsa ho etsa lifilimi (joalo ka diethylene glycol butyl acetate), porridge hydroxyethyl cellulose e ka eketsoa ka kotloloho penteng, kamora ho eketsa, tsoela pele ho sisinya ho fihlela e qhibiliha ka ho feletseng.
Ka scraping lebota putty
Hona joale, Chaena e ka har'a metse e mengata ea ho hanyetsa metsi, ho hanyetsa swab ea putty ea tšireletso ea tikoloho ho nkoa ka botebo ke batho, lilemong tse 'maloa tse fetileng, hobane putty e entsoeng ka sekhomaretsi se hlahisa tšenyo ea khase ea formaldehyde bophelong ba batho. Sekhomaretsi se entsoe ka joala ba polyvinyl le formaldehyde acetal reaction.Kahoo thepa ena butle-butle e felisoa ke batho, 'me ho nkeloa sebaka ha thepa ena ke cellulose ether letoto la lihlahisoa, ke ho re, ntshetsopele ea thepa ea ho haha ea tšireletso ea tikoloho, selulose ke mofuta o le mong feela oa thepa hona joale.
Ka har'a metsi, putty e arotsoe ka phofo e omileng ea putty le putty peste ea mefuta e 'meli, mefuta ena e' meli ea putty hangata e khetha methyl cellulose le hydroxypropyl methyl mefuta e 'meli, viscosity specifikation hangata e 40,000-75000cps lipakeng tsa tse nepahetseng ka ho fetisisa, karolong e kholo ea selulose. ka putty ke ho boloka metsi, tlamahano, lubrication le litlamorao tse ling.
Hobane sebopeho sa putty sa moetsi e mong le e mong ha se tšoane, tse ling ke khalsiamo e bohlooho, k'halsiamo e bobebe, samente e tšoeu, tse ling ke phofo ea gypsum, calcium e bohlooho, khalsiamo e khanyang, joalo-joalo. ha li tšoane, kakaretso ea ho eketsa ke 2 ‰ -3 ‰ kapa joalo.
