Putty le samente ke lisebelisoa tsa bohlokoa kahong, tse sebelisetsoang ho theha libaka tse boreleli le ho netefatsa botsitso ba sebopeho.Ts'ebetso ea lisebelisoa tsena e susumetsoa haholo ke ho hlophisoa ha tsona le li-additives tse sebelisoang.Methyl Hydroxyethyl Cellulose (MHEC) ke tlatsetso ea bohlokoa ho ntlafatsa boleng le ts'ebetso ea putty le plaster.
Ho utloisisa Methyl Hydroxyethyl Cellulose (MHEC)
MHEC ke cellulose ether e tsoang ho cellulose ea tlhaho, e fetotsoeng ka mekhoa ea methylation le hydroxyethylation.Phetoho ena e fana ka ho qhibiliha ha metsi le lisebelisoa tse fapaneng tse sebetsang ho selulose, ho etsa hore MHEC e be tlatsetso e fapaneng ea thepa ea kaho.
Lintho tsa Lik'hemik'hale:
MHEC e khetholloa ke bokhoni ba eona ba ho etsa tharollo ea viscous ha e qhibiliha ka metsing.
E na le bokhoni bo babatsehang ba ho etsa filimi, e fana ka lera le sireletsang le matlafatsang ho tšoarella ha putty le plaster.
Thepa ea Sebele:
E eketsa ho bolokoa ha metsi lihlahisoa tse thehiloeng ho samente, tse bohlokoa bakeng sa pheko e nepahetseng le nts'etsopele ea matla.
MHEC e fana ka thixotropy, e ntlafatsang ho sebetsa le boiketlo ba tšebeliso ea putty le plaster.
Karolo ea MHEC ho Putty
Putty e sebelisetsoa ho tlatsa mefokolo e menyenyane maboteng le siling, e fana ka sebaka se boreleli bakeng sa ho penta.Ho kenyelletsoa ha MHEC ho li-putty formulations ho fana ka melemo e mengata:
Tšebeliso e ntlafetseng:
MHEC e ntlafatsa ho ata ha putty, ho etsa hore ho be bonolo ho e sebelisa le ho hasana ka mokhoa o mosesaane le o lekanang.
Lintho tsa eona tsa thixotropic li lumella putty hore e lule e le teng ka mor'a kopo ntle le ho sisinyeha.
Paballo e Ntlafetseng ea Metsi:
Ka ho boloka metsi, MHEC e netefatsa hore putty e lula e sebetsa ka nako e telele, e fokotsa kotsi ea ho omisa pele ho nako.
Nako ena e atolositsoeng ea ho sebetsa e lumella liphetoho tse ntle le ho boreleli nakong ea kopo.
Ho Adhesion ka ho Fetisisa:
MHEC e ntlafatsa thepa ea sekhomaretsi ea putty, e netefatsa hore e khomarela li-substrates tse fapaneng joalo ka konkreite, gypsum le litene.
Khomaretsi e ntlafalitsoeng e fokotsa monyetla oa ho phatloha le ho arohana ha nako e ntse e feta.
Keketseho ea Nako e Tšoarellang:
Bokhoni ba ho etsa lifilimi ba MHEC bo etsa mokoallo o sireletsang o matlafatsang ho tšoarella ha putty layer.
Tšitiso ena e sireletsa bokaholimo bo ka tlase ho mongobo le maemo a tikoloho, ho lelefatsa bophelo ba kopo ea putty.
Karolo ea MHEC ho Plaster
Plaster e sebelisoa ho etsa libaka tse boreleli, tse tšoarellang maboteng le siling, hangata e le motheo oa ho qetela mosebetsi.Melemo ea MHEC mefuteng ea samente e bohlokoa:
Ho Ntlafatsoa ke Tumellano le Tšebeliso ea Mosebetsi:
MHEC e fetola rheology ea plaster, e nolofalletsa ho kopanya le ho e sebelisa.
E fana ka sebopeho se tsitsitseng, se monate se nolofatsang ts'ebetso e boreleli ntle le makukuno.
Paballo e Ntlafetseng ea Metsi:
Pholiso e nepahetseng ea samente e hloka ho boloka mongobo o lekaneng.MHEC e etsa bonnete ba hore samente e boloka metsi nako e telele, e lumellang hore ho be le metsi a feletseng a likaroloana tsa samente.
Mokhoa ona o laoloang oa ho folisa o fella ka lera le matla le le tšoarellang haholoanyane.
Ho fokotseha ha Cracks:
Ka ho laola sekhahla sa ho omisa, MHEC e fokotsa kotsi ea mapetso a honyehang a ka bang teng haeba samente e omella kapele haholo.
Sena se lebisa holim'a samente e tsitsitseng le e ts'oanang.
Kamano e betere le Momahano:
MHEC e ntlafatsa thepa ea sekhomaretsi ea samente, e etsa bonnete ba hore e tlamahane hantle le li-substrates tse fapaneng.
Momahano o ntlafetseng ka har'a matrix a samente e fella ka qetello e tsitsitseng le e tšoarellang nako e telele.
Mekhoa ea Ntlafatso ea Ts'ebetso
Fetola Viscosity:
MHEC e eketsa viscosity ea tharollo ea metsi, e leng ea bohlokoa ho boloka botsitso le homogeneity ea putty le plaster.
Phello e matla ea MHEC e tiisa hore metsoako e lula e tsitsitse nakong ea ho boloka le ho sebelisoa, ho thibela ho arohana ha likarolo.
Taolo ea Rheology:
Sebopeho sa thixotropic sa MHEC se bolela hore putty le plaster li bonts'a boits'oaro ba ho kuta, ho se be le viscous tlas'a khatello ea ho kuta (nakong ea kopo) le ho fumana viscosity ha u phomotse.
Thepa ena e lumella ho sebelisoa habonolo le ho qhekella ha lisebelisoa, ho lateloa ke ho beha kapele ntle le ho sisinyeha.
Tlhahiso ea lifilimi:
MHEC e etsa filimi e feto-fetohang le e tsoelang pele ha e omisa, e leng ho eketsang matla a mochine le ho hanyetsa ha putty le plaster e sebelisitsoeng.
Filimi ena e sebetsa e le tšitiso khahlanong le maemo a tikoloho a kang ho fetoha ha mongobo le mocheso, ho matlafatsa nako e telele ea ho qetela.
Melemo ea Tikoloho le Moruo
Keketso e tsitsitseng:
E nkiloe ho selulose ea tlhaho, MHEC ke motsoako o ka senyehang oa tlhaho le oa tikoloho.
Tšebeliso ea eona e tlatsetsa ho tsitsitseng ha thepa ea kaho ka ho fokotsa tlhokahalo ea li-additives tsa maiketsetso le ho ntlafatsa ts'ebetso ea lisebelisoa tsa tlhaho.
Litšenyehelo-ka katleho:
Ho sebetsa hantle ha MHEC ho ntlafatseng ts'ebetso ea putty le plaster ho ka lebisa ho bolokeheng ha litšenyehelo ka nako e telele.
Ho tsitsa ho matlafalitsoeng le litlhoko tse fokotsehileng tsa tlhokomelo li theola litšenyehelo tse amanang le litokiso le likopo hape.
Matla a Matla:
Ho ntlafala ho boloka metsi le ho sebetsa ho fokotsa tlhokahalo ea ho kopanya khafetsa le liphetoho tsa kopo, ho boloka matla le litšenyehelo tsa basebetsi.
Ts'ebetso e ntlafalitsoeng ea pheko e tsamaisoang ke MHEC e etsa bonnete ba hore lisebelisoa li fihlella matla a maholo ka ho kenya letsoho ka matla a fokolang.
Methyl Hydroxyethyl Cellulose (MHEC) ke tlatsetso ea bohlokoa ho ntlafatseng ts'ebetso ea putty le plaster.Bokhoni ba eona ba ho ntlafatsa ts'ebetso, ho boloka metsi, ho khomarela le ho tšoarella ho etsa hore e be ea bohlokoa kahong ea sejoale-joale.Ka ho ntlafatsa botsitso, thepa ea kopo, le boleng ba kakaretso ba putty le plaster, MHEC e kenya letsoho mekhoeng ea kaho e sebetsang hantle le e tsitsitseng.Melemo ea eona ea tikoloho le ho baballa ha eona litšenyehelo li matlafatsa karolo ea eona e le karolo ea bohlokoa linthong tsa kaho.Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, tšebeliso ea MHEC ka li-putty le plaster formulations e ka 'na ea ata le ho feta, e leng se etsang hore ho be le tsoelo-pele ea theknoloji ea mohaho le boleng.
