Phofo ea putty ke thepa ea kaho e sebelisoang haholo, e sebelisoang haholo bakeng sa ho leka-lekanya lebota, ho tlatsa mapetso le ho fana ka bokaholimo bo boreleli bakeng sa ho penta le ho khabisa ka mor'a moo. Cellulose ether ke e 'ngoe ea lintho tsa bohlokoa tse tlatsetsang phofong ea putty, e ka ntlafatsang haholo ts'ebetso ea kaho le boleng ba phofo ea putty. Sengoloa sena se tla hlahisa ka botlalo ts'ebeliso e khethehileng ea li-ether tsa cellulose phofong ea putty le bohlokoa ba eona indastering ea kaho.
1. Thepa ea motheo le mesebetsi ea li-ether tsa selulose
Cellulose ether ke mofuta oa motsoako oa polymer o qhibilihang ka metsing o fumanoang ka phetoho ea lik'hemik'hale ho sebelisoa cellulose ea tlhaho e le thepa e tala. Sebopeho sa eona sa limolek'hule se na le palo e kholo ea lihlopha tse hydrophilic (tse kang hydroxyl, methoxy, jj.), tse fanang ka cellulose ether ho qhibiliha ha metsi hantle le bokhoni ba ho teteana. Tšebelisong ea phofo ea putty, karolo ea bohlokoa ea cellulose ether e bonahala haholo-holo likarolong tse latelang:
Phello ea ho teteana
Cellulose ether e ka eketsa haholo viscosity ea putty powder slurry, e etsa hore e be le thixotropy e ntle le botsitso, ka hona e nolofatsa kaho. Ho phaella moo, e ka boela ea fetola litšobotsi tsa rheological tsa slurry ho thibela phofo ea putty ho phalla kapa ho thella leboteng, ho netefatsa tsoelo-pele e boreleli ea kaho.
Ho boloka metsi
Ho boloka metsi a mangata ha cellulose ether ke e 'ngoe ea litšobotsi tsa eona tsa bohlokoa ha e sebelisoa phofong ea putty. Nakong ea ts'ebetso ea kaho, kamora hore phofo ea putty e sebelisoe leboteng, mouoane oa metsi o ka etsa hore phofo ea putty e ome le ho petsoha. Cellulose ether e ka liehisa tahlehelo ea metsi ka katleho, ea etsa hore slurry e lokolle metsi butle-butle nakong ea ts'ebetso ea ho omisa, ka hona e ntlafatsa ho khomarela ha putty, e qoba ho oma le ho petsoha, le ho netefatsa hore bokaholimo ba lebota bo boreleli.
Ntlafatsa bokgoni ba ho sebetsa
Boteng ba ether ea cellulose bo ntlafatsa haholo ts'ebetso ea kaho ea phofo ea putty. Mohlala, e ka ntlafatsa ho tenyetseha ha putty, e leng se nolofalletsang basebetsi ba kaho ho hohla putty ka ho lekana. Ho phaella moo, ether ea cellulose e ka boela ea fokotsa tlhahiso ea lipululana holim'a putty le ho ntlafatsa boreledi, ka hona e ntlafatsa phello ea mokhabiso.
Eketsa lihora tsa ho bula
Kahong, nako ea ho buloa ha phofo ea putty, ke hore, nako ho tloha ha e sebelisoa ho ea ho omelleng le ho tiea ha thepa, ke parameter ea bohlokoa eo basebetsi ba kaho ba e elang hloko. Cellulose ether e ka eketsa nako ea ho buloa ha putty, ea fokotsa manonyeletso le ho se lekane nakong ea kaho, ka hona ea ntlafatsa botle ba lebota ka kakaretso.
2. Tšebeliso ea ether ea cellulose maemong a fapaneng a phofo ea putty
Sesepa sa lebota sa kahare
Ha ho sebelisoa putty ea leboteng ea ka hare, ether ea cellulose ha e ntlafatse feela ho sebetsa hantle, empa e ka boela ea fetola ho phalla le ho khomarela ha putty ho netefatsa hore bokaholimo ba lebota bo boreleli le ho khomarela. Ho phaella moo, ts'ebetso e phahameng ea ho boloka metsi ea ether ea cellulose e ka thibela putty ho petsoha ka lebaka la mouoane o potlakileng oa metsi nakong ea ts'ebetso ea ts'ebeliso, 'me e loketse litlhoko tsa botsitso ba nako e telele libakeng tse omileng tsa ka tlung.
Sesepa sa lebota sa kantle
Putty ea leboteng ea kantle e hloka ho ba le khanyetso e matla ea boemo ba leholimo le khanyetso ea mapetso, hobane bokaholimo ba leboteng la kantle bo tla angoa ke boemo ba leholimo, liphapang tsa mocheso le lintlha tse ling. Tšebeliso ea ether ea cellulose ho putty ea leboteng ea kantle e ka ntlafatsa haholo ho boloka metsi, khanyetso ea mapetso le ho khomarela, e e lumella ho ikamahanya le liphetoho tikolohong ea kantle le ho lelefatsa bophelo ba eona ba ts'ebeletso. Ho phaella moo, ether ea cellulose e ka boela ea thusa putty ho ntlafatsa khanyetso ea eona ea UV, khanyetso ea ho hatsela le thepa e meng, e le hore putty ea leboteng ea kantle e ntse e ka boloka thepa e tsitsitseng ea 'mele tlas'a maemo a kantle.
setlolo se sa keneleng metsi
Putty e sa keneleng metsi e loketse dibaka tse nang le mongobo o mongata jwalo ka matloana le dikhitjhini, mme e hloka ho se kenelle metsi ho hoholo le ho hanela metsi ho putty. Cellulose ether e ka ntlafatsa tshebetso ya putty e sa keneleng metsi motheong wa ho netefatsa ho kgomarela ha yona hantle le ho sebetsa hantle. Ho feta moo, ditlamorao tsa ho teteana le ho boloka metsi tsa ether ya cellulose di nolofalletsa putty e sa keneleng metsi ho boloka botsitso bo botle dibakeng tse nang le mongobo o mongata le ho qoba mathata a hlobo maboteng.
Setlolo se khabisitsoeng sa boleng bo holimo
Putty e khabisitsoeng ea boleng bo holimo e na le litlhoko tse phahameng haholo bakeng sa ho ba bataletse le ho ba boreleli, 'me hangata e sebelisoa matlong a maemo a holimo, lihoteleng le libakeng tse ling. Cellulose ether e ka thusa ho ntlafatsa likaroloana tsa putty, ea ntlafatsa boreledi ba bokaholimo, ea ntlafatsa ho tenyetseha le ho sebetsa ha putty, ea fokotsa lipululana le li-seam, ea etsa hore phello ea mokhabiso e be e phethahetseng haholoanyane, le ho fihlela litlhoko tsa mokhabiso tsa libaka tse maemong a holimo.
3. Khetho ea tekheniki ea ether ea cellulose ka har'a phofo ea putty
Ho ya ka ditlhoko tsa tshebediso le ditlhoko tse fapaneng tsa tshebetso ya phofo ya putty, di-ether tse latelang tsa cellulose di atisa ho sebediswa indastering ya kaho:
Hydroxypropyl methylcellulose (HPMC)
HPMC ke setlatsetso se sebediswang haholo sa kaho se nang le ditlamorao tse ntle tsa ho boloka metsi le ho teteana. E sebediswa haholo disebedisweng tsa kaho tse kang putty ya leboteng ya kahare le kantle, dikhomaretsi tsa thaele, le di-mortar tsa ho plaster. E ka ntlafatsa ho hanyetsa ho sag le ho sebetsa ha phofo ya putty, mme e loketse haholo ditlhoko tsa putty e nang le viscosity e phahameng.
Hydroxyethylmethylcellulose (HEMC)
HEMC e na le ts'ebetso e ntle ea ho boloka metsi le botsitso, haholo-holo libakeng tse mocheso o tlase, 'me e ntse e ka boloka ho qhibiliha ho hotle, kahoo e loketse ho sebelisoa ho putty ea leboteng la kantle. Ho feta moo, HEMC e na le phello e ntle haholo ho ntlafatseng ho hasana le ho tšoana ha phofo ea putty, e leng se etsang hore bokaholimo bo be boreledi le boreledi kamora ho penta.
Carboxymethyl cellulose (CMC)
CMC ke setei se qhibilihisang metsi. Le hoja e na le thepa e tlase ea ho boloka metsi le ho thibela ho oa, litšenyehelo tsa eona li tlase. Hangata e sebelisoa ka phofo ea putty e sa hlokeng ho boloka metsi a mangata 'me e loketse lits'ebetso tse akaretsang tsa putty ea leboteng.
4. Litebello le mekhoa ea li-ether tsa cellulose indastering ea phofo ea putty
Ka ntshetsopele e tswelang pele ya indasteri ya kaho, ditlhoko tsa batho bakeng sa boleng, tshireletso ya tikoloho le botle ba thepa ya mokhabiso di eketsehile butle-butle, mme menyetla ya tshebediso ya di-ether tsa cellulose e se e pharaletse haholo. Mokgweng wa ntshetsopele ya indasteri ya phofo ya putty nakong e tlang, tshebediso ya ether ya cellulose e tla shebana le dintlha tse latelang:
E tala ebile e sireletsa tikoloho
Hona jwale, thepa ya kaho e sireletsang tikoloho ke taba e chesang indastering ya kaho. Jwalo ka thepa ya polymer e tswang ho cellulose ya tlhaho, cellulose ether e dumellana le mohopolo wa tshireletso ya tikoloho e tala mme e ka fokotsa tshilafatso ya mokhabiso ka katleho. Nakong e tlang, dihlahiswa tse ngata tsa VOC tse tlase (metswako ya tlhaho e feto-fetohang) le dihlahiswa tsa ether ya cellulose tse sebetsang hantle di tla ntshetswa pele le ho sebediswa.
E sebetsa hantle ebile e bohlale
Ntlafatso e tswelang pele ya ether ya cellulose e nolofalletsa phofo ya putty ho boloka tshebetso e tsitsitseng dibakeng tse rarahaneng. Mohlala, ka ntlafatso ya sebopeho sa dimolek'hule le ho eketswa ha di-additives, phofo ya putty e na le bokgoni bo matla ba ho ikamahanya le maemo le ho iphekola, e leng se etsang hore thepa ya kaho e be bohlale le e sebetsang hantle.
Ho feto-fetoha ha maemo
Leha ho ntse ho ntlafatsoa thepa ea motheo ea phofo ea putty, li-ether tsa cellulose li ka boela tsa etsa hore phofo ea putty e be le mesebetsi e meng e kang ea antibacterial, anti-moldew, le anti-UV ho fihlela litlhoko tsa maemo a khethehileng a ts'ebeliso.
Tšebeliso ea ether ea cellulose ka har'a phofo ea putty ha e ntlafatse feela ts'ebetso ea kaho le ho tšoarella ha phofo ea putty, empa hape e ntlafatsa haholo phello ea mokhabiso oa lebota, e fihlela litlhoko tsa meaho ea sejoale-joale bakeng sa ho ba bataletse ha lebota, ho boreleli le ho tšoarella. Ka nts'etsopele e tsoelang pele ea indasteri ea kaho, ts'ebeliso ea ether ea cellulose ka har'a phofo ea putty e tla ba ngata le ho feta, e sutumelletse lisebelisoa tsa mokhabiso oa moaho ho ea ts'ebetsong e phahameng le ts'ireletsong ea tikoloho.
