Putty powder ke thepa ea kaho e sebelisoang hangata, e sebelisetsoang ho lokisa marako, ho tlatsa mapetsong le ho fana ka sebaka se boreleli bakeng sa ho penta le ho khabisa ka mor'a moo. Cellulose ether ke e 'ngoe ea li-additives tsa bohlokoa ka putty powder, e ka ntlafatsang haholo ts'ebetso ea kaho le boleng ba putty powder. Sehlooho sena se tla hlahisa ka ho qaqileng tšebeliso e khethehileng ea cellulose ethers ka putty powder le bohlokoa ba eona ho indasteri ea kaho.
1. Lintho tsa motheo le mesebetsi ea cellulose ethers
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 tsa hydrophilic (tse kang hydroxyl, methoxy, joalo-joalo), e fanang ka cellulose ether ho qhibiliha ha metsi hantle le bokhoni ba ho teteka. Tšebelisong ea putty powder, karolo ea bohlokoa ea cellulose ether e bonahala haholo-holo likarolong tse latelang:
Phello e teteaneng
Cellulose ether e ka eketsa haholo viscosity ea putty powder slurry, e etsa hore e be le thixotropy e ntle le botsitso, kahoo e bebofatse kaho. Ho phaella moo, e ka boela ea fetola thepa ea rheological ea slurry ho thibela phofo ea putty ho phalla kapa ho thella leboteng, ho netefatsa tsoelo-pele e ntle ea kaho.
Ho boloka metsi
Ho boloka metsi a phahameng a cellulose ether ke e 'ngoe ea litšobotsi tsa eona tsa bohlokoa ha e sebelisoa ka putty powder. Nakong ea ts'ebetso ea kaho, ka mor'a hore phofo ea putty e sebelisoe leboteng, mouoane oa metsi o ka etsa hore phofo ea putty e omelle le ho ebola. Cellulose ether e ka lieha ho lahleheloa ke metsi ka katleho, e etsa hore slurry e lokolle metsi butle-butle nakong ea ts'ebetso ea ho omisa, kahoo e ntlafatsa ho khomarela ha putty, ho qoba ho omisa le ho senya, le ho etsa bonnete ba hore lebota le boreleli.
Ntlafatsa ts'ebetso
Ho ba teng ha cellulose ether ho ntlafatsa haholo ts'ebetso ea kaho ea putty powder. Ka mohlala, e ka ntlafatsa ho tenyetseha ha putty, ho nolofaletsa basebetsi ba kaho ho phunya putty ka ho lekana. Ho phaella moo, cellulose ether e ka boela ea fokotsa moloko oa li-bubble holim'a putty le ho ntlafatsa boreleli, kahoo e ntlafatsa phello ea mokhabiso.
Eketsa lihora tsa ho bula
Ha ho hahoa, nako ea ho bula ea putty powder, ke hore, nako ea ho tloha ho kopo ho ea ho omisa le ho tiisa thepa, ke parameter ea bohlokoa eo basebetsi ba kaho ba e ela hloko. Cellulose ether e ka eketsa nako ea ho bula ea putty, ea fokotsa manonyeletso le ho se lekane nakong ea kaho, kahoo e ntlafatsa botle ba lerako ka kakaretso.
2. Ho sebelisoa ha cellulose ether maemong a fapaneng a putty powder
Ka hare lebota putty
Tšebelisong ea bokahare ba lerako la putty, cellulose ether ha e ntlafatse feela ho sebetsa, empa e ka boela ea fetola metsi le ho khomarela ha putty ho etsa bonnete ba ho boreleli le ho khomarela lebota. Ho phaella moo, ts'ebetso e phahameng ea ho boloka metsi ea cellulose ether e ka thibela putty ho senya ka lebaka la ho fetoha mouoane ka potlako ha metsi nakong ea ts'ebetso ea kopo, 'me e loketse litlhoko tsa nako e telele tsa botsitso libakeng tse omeletseng tsa ka tlung.
Ka ntle lebota putty
Bokantle ba lebota la putty bo hloka ho ba le khanyetso e matla ea leholimo le ho hanyetsa mapheo, hobane bokaholimo ba lebota la kantle bo tla angoa ke boemo ba leholimo, phapang ea mocheso le lintlha tse ling. Tšebeliso ea cellulose ether ka bokantle ba lebota la putty e ka ntlafatsa haholo ho boloka metsi a eona, ho hanyetsa ho phatloha le ho khomarela, ho e lumella ho ikamahanya le liphetoho tikolohong ea kantle le ho lelefatsa bophelo ba eona ba ts'ebeletso. Ho phaella moo, cellulose ether e ka boela ea thusa putty hore e ntlafatse khanyetso ea eona ea UV, ho hanyetsa ha leqhoa le lisebelisoa tse ling, e le hore bokantle ba lebota la putty bo ntse bo ka boloka thepa ea 'mele e tsitsitseng tlas'a maemo a ka ntle.
putty e sa keneleng metsi
Putty e sa keneleng metsi e loketse maemo a mongobo o phahameng joalo ka likamore tsa ho hlapela le kichine, 'me e hloka ho thibela metsi ho phahameng le ho hanyetsa metsi ha putty. Cellulose ether e ka ntlafatsa ts'ebetso e sa keneleng metsi ea putty motheong oa ho netefatsa hore e khomarela hantle le ho sebetsa hantle. Ho phaella moo, liphello tse teteaneng le tse bolokang metsi tsa cellulose ether li nolofalletsa putty e sa keneleng metsi ho boloka botsitso bo botle libakeng tse nang le mongobo o phahameng le ho qoba mathata a hlobo marakong.
Li-putty tse khabisitsoeng tse phahameng
Li-putty tse khabisitsoeng ka mokhoa o phahameng li na le litlhoko tse phahameng haholo bakeng sa ho bata le ho khabisoa, 'me hangata li sebelisoa libakeng tsa bolulo tse phahameng, lihotele le libaka tse ling. Cellulose ether e ka thusa ho hloekisa likaroloana tsa putty, ho ntlafatsa boreleli holim'a metsi, ho ntlafatsa ho feto-fetoha ha maemo le ho sebetsa ha putty, ho fokotsa li-bubble le seams, ho etsa hore mokhabiso o be o phethahetseng haholoanyane, le ho finyella litlhoko tsa mokhabiso oa libaka tse phahameng.
3. Khetho ea theknoloji ea cellulose ether ka putty powder
Ho ea ka litlhoko tsa kopo le litlhoko tse fapaneng tsa ts'ebetso ea putty powder, li-ether tse latelang tsa cellulose li sebelisoa hangata indastering ea kaho:
Hydroxypropyl methylcellulose (HPMC)
HPMC ke tlatsetso ea kaho e sebelisoang hangata e nang le ho boloka metsi hantle le litlamorao tse teteaneng. E sebelisoa haholo linthong tsa kaho tse kang putty ea ka hare le kantle ea lebota, likhomaretsi tsa lithaele le lirafshoa tsa ho lipola. E ka ntlafatsa ho hanyetsa sag le ho sebetsa ha putty powder, 'me e loketse ka ho khetheha litlhoko tsa li-high-viscosity putty.
Hydroxyethylmethylcellulose (HEMC)
HEMC e na le ts'ebetso e ntle ea ho boloka metsi le botsitso, haholo-holo maemong a mocheso o tlase, 'me e ntse e ka boloka ho qhibiliha ha metsi, kahoo e loketse ho sebelisoa ka ntle ho lebota putty. Ho phaella moo, HEMC e na le phello e ntle haholo ea ho ntlafatsa ho qhalakanngoa le ho tšoana ha phofo ea putty, ho etsa hore bokaholimo bo be bonolo 'me bo be bonolo ka mor'a ho roala.
Carboxymethyl cellulose (CMC)
CMC ke setenya se qhibilihang ka metsing. Le hoja e na le thepa e tlaase ea ho boloka metsi le anti-sag, theko ea eona e tlaase. Hangata e sebelisoa ka putty powder e sa hlokeng ho boloka metsi a mangata 'me e loketse lisebelisoa tse akaretsang tsa ka hare ho lebota la putty.
4. Litebello le mekhoa ea li-cellulose ethers indastering ea putty powder
Ka tsoelo-pele e tsoelang pele ea indasteri ea kaho, litlhoko tsa batho bakeng sa boleng, tšireletso ea tikoloho le aesthetics ea thepa ea mokhabiso li eketsehile butle-butle, 'me litebello tsa tšebeliso ea li-cellulose ethers li se li ntse li eketseha. Mokhoa oa nakong e tlang oa nts'etsopele ea indasteri ea phofo ea putty, ts'ebeliso ea cellulose ether e tla shebana le lintlha tse latelang:
Botala le tikoloho
Hajoale, thepa ea kaho e se nang tikoloho ke taba e chesang haholo indastering ea kaho. E le thepa ea polymer e nkiloeng ho selulose ea tlhaho, cellulose ether e lumellana le khopolo ea ho sireletsa tikoloho e tala 'me e ka fokotsa ka katleho tšilafalo ea mokhabiso. Nakong e tlang, lihlahisoa tse ngata tse tlaase tsa VOC (li-volatile organic compounds) le lihlahisoa tse phahameng tsa cellulose ether li tla hlahisoa le ho sebelisoa.
E sebetsa hantle ebile e bohlale
Ntlafatso e tsoelang pele ea cellulose ether e nolofalletsa putty powder ho boloka ts'ebetso e tsitsitseng libakeng tse rarahaneng. Ka mohlala, ka ho ntlafatsa sebopeho sa limolek'hule le ho eketsoa ha li-additives, putty powder e na le matla a ho ikamahanya le maemo le thepa ea ho ipholisa, ho etsa hore thepa ea mohaho e be bohlale le ho sebetsa hantle.
Ho feto-fetoha ha maemo
Ha e ntse e ntlafatsa thepa ea motheo ea putty powder, cellulose ethers e ka boela ea etsa hore putty powder e be le mesebetsi e eketsehileng e kang antibacterial, anti-mildew, le anti-UV ho finyella litlhoko tsa maemo a khethehileng a kopo.
Tšebeliso ea cellulose ether ka putty powder ha e ntlafatse feela ts'ebetso ea kaho le ho tšoarella ha phofo ea putty, empa hape e ntlafatsa haholo phello ea mokhabiso oa lerako, e finyella litlhoko tsa mehaho ea morao-rao bakeng sa lerako le bataletseng, boreleli le ho tšoarella. . Ka nts'etsopele e tsoelang pele ea indasteri ea kaho, ts'ebeliso ea li-cellulose ethers ka putty powder e tla ba ngata le ho feta, e sutumelletsa lisebelisoa tsa mokhabiso oa moaho ho ea ts'ebetsong e phahameng le ts'ireletso ea tikoloho.
