Tlhokahalo ea ho eketsa selulose ho lihlahisoa tsa seretse le tsa gypsum

Lihlahisoa tse thehiloeng ho seretse le gypsum ke lintlha tsa bohlokoa indastering ea kaho, li sebetsa e le li-agent tse tlamang thepa e fapaneng ea moaho. Lihlahisoa tsena li tsoela pele ho nchafatsoa le ntlafatso ho fihlela litlhoko tse lulang li fetoha tsa kaho ea sejoale-joale. Keketso e 'ngoe ea bohlokoa linthong tsena ke cellulose, e bapalang karolo ea bohlokoa ho ntlafatsa ts'ebetso ea bona le thepa ea bona.

Ho utloisisa Cellulose:

Cellulose ke polysaccharide ea tlhaho e fumanehang maboteng a lisele tsa limela. Ke polymer e ngata ka ho fetisisa lefatšeng 'me e sebetsa e le karolo ea mantlha ea meralo ea limela. Ka lik'hemik'hale, limolek'hule tsa selulose li na le liketane tse melang tsa likarolo tsa tsoekere tse hokahaneng ka libonto tsa β(1→4) tsa glycosidic. Kaheho ena e ikhethang ea limolek'hule e fana ka matla a ikhethang, botsitso le ho mamella cellulose.

Indastering ea kaho, selulose e fumana ts'ebeliso e pharaletseng e le tlatsetso ea lisebelisoa tse fapaneng tsa kaho, ho kenyeletsoa seretse le lihlahisoa tse thehiloeng ho gypsum. Kenyelletso ea eona e sebeletsa merero e mengata, e rarolla mathata a 'maloa a kopaneng nakong ea tlhahiso, ts'ebeliso le mekhahlelo ea ts'ebetso ea lisebelisoa tsena.

Mesebetsi ea Cellulose ka Seretse le Lihlahisoa tse thehiloeng ho Gypsum:

Paballo ea Metsi:
E 'ngoe ea mesebetsi ea mantlha ea selulose ka har'a seretse le lihlahisoa tse thehiloeng ho gypsum ke bokhoni ba eona ba ho boloka metsi. Likhoele tsa cellulose li na le bokhoni bo phahameng ba ho monya le ho boloka metsi ka har'a sebopeho sa tsona. Ha e eketsoa ho lisebelisoa tsena, selulose e sebetsa e le moemeli oa ho boloka metsi, ho netefatsa hore ho na le metsi a lekaneng a likarolo tsa cementitious kapa gypsum. Ts'ebetso ena ea nako e telele ea hydration e ntlafatsa ho sebetsa ha motsoako, ho lumella ts'ebeliso e ntle le ho khomarela li-substrates.

Tšebeliso e Ntlafetseng le Momahano:
Ho ba teng ha likhoele tsa selulose ka har'a seretse le lihlahisoa tse thehiloeng ho gypsum ho ntlafatsa ts'ebetso ea tsona le momahano. Likhoele tsa cellulose li sebetsa e le moemeli oa ho matlafatsa, ka katleho li hasana hohle motsoako le ho etsa marang-rang a mararo. Marang-rang ana a matlafatsa matrix, a thibela ho arohana le ho ntlafatsa ho lumellana ka kakaretso le homogeneity ea thepa. Ka lebaka leo, motsoako o ba bonolo ho sebetsana, ho jala, le sebōpeho, e leng se lebisang ho ntlafatseng ts'ebetso nakong ea mesebetsi ea kaho.

Thibelo ea Crack le Taolo ea Shrinkage:
Karolo e 'ngoe ea bohlokoa ea selulose linthong tsena ke tlatsetso ea eona ho thibelo ea makhopho le taolo ea ho honyela. Nakong ea mekhahlelo ea ho omisa le ho folisa, lihlahisoa tse entsoeng ka seretse le gypsum li ka 'na tsa fokotseha le ho phunyeha ka lebaka la tahlehelo ea mongobo le likhatello tsa ka hare. Likhoele tsa cellulose li thusa ho fokotsa litaba tsena ka ho fana ka matlafatso ea kahare le ho fokotsa sebopeho sa maqhetsoana a manyane. Ka ho ntlafatsa matla le ductility ea thepa, selulose e ntlafatsa ho hanyetsa ha eona ho phunyeha ho bakoang ke ho fokotseha, ka tsela eo ho khothalletsa ho tšoarella ha nako e telele le botšepehi ba sebopeho.

Lintho tse Ntlafetseng tsa Mechini:
Matlafatso ea cellulose e fana ka thepa e ntlafalitsoeng ea mochini ho seretse le lihlahisoa tse thehiloeng ho gypsum. Keketso ea likhoele tsa cellulose e eketsa matla a ho feto-fetoha ha thepa, ho hanyetsa tšusumetso, le ho tšoarella. Ntlafatso ena ea ts'ebetso ea mochini e molemo ka ho khetheha lits'ebetsong moo thepa e tlas'a meroalo ea sebopeho, matla a kantle kapa maemo a tikoloho. Ka ho matlafatsa matrix le ho fokotsa kotsi ea ho hlōleha, cellulose e ntlafatsa ts'ebetso ea kakaretso le nako e telele ea mohaho o phethiloeng.

Ho lumellana le Mekhoa e Tsoelang Pele:
Cellulose e tsoa mehloling e ka nchafatsoang joalo ka makhasi a lehong, k'hothone, kapa pampiri e tsosolositsoeng, e etsa hore e tšoarelle ka tlhaho ebile e se na tikoloho. Tšebeliso ea eona ho lihlahisoa tse entsoeng ka seretse le gypsum e tsamaisana le khatiso e ntseng e hola ea indasteri mabapi le mekhoa ea kaho ea moshoelella le boikitlaetso ba kaho e tala. Ka ho kenyelletsa li-additives tsa cellulose, bahlahisi ba ka fokotsa ho itšetleha ha bona ho lisebelisoa tse sa tsosolositsoeng le ho fokotsa tšusumetso ea tikoloho ea lihlahisoa tsa bona. Ho tsamaellana hona le litloaelo tse tšoarellang ho boetse ho hatisa bohlokoa ba selulose linthong tsa sejoale-joale tsa kaho.

tlatsetso ea selulose ho seretse le lihlahisoa tse thehiloeng ho gypsum ha se taba ea boikhethelo feela empa ke tlhokahalo e susumetsoang ke tlhoko ea ts'ebetso e ntlafetseng, ho tšoarella le ho tšoarella. Cellulose e fana ka mesebetsi e mengata, ho kenyeletsa ho boloka metsi, ho ntlafatsa ts'ebetso, ho thibela ho phatloha, le ho matlafatsa mechine. Thepa ea eona e ikhethang le ho lumellana le mekhoa e tsitsitseng e etsa hore e be tlatsetso ea bohlokoa ho thepa ea morao-rao ea kaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, bohlokoa ba selulose ka har'a seretse le lihlahisoa tse thehiloeng ho gypsum bo tla hola feela, ho bopa bokamoso ba mekhoa ea kaho e tsitsitseng le e tsitsitseng.
