Tšebeliso ea Hydroxyethyl Cellulose Liaparong
Hydroxyethyl cellulose (HEC)ke polymer e feto-fetohang e sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ntle ea ho tenya, ho tsitsisa le ho etsa filimi. Lefapheng la lipeipi, HEC e bapala karolo ea bohlokoa ho ntlafatseng viscosity, ho ntlafatsa thepa ea rheological, le ho fana ka sebopeho se setle sa filimi. E bua ka tšusumetso ea HEC ts'ebetsong ea ho peipi, joalo ka tšusumetso ea eona viscosity, ho leka-lekana, ho hanyetsa ho sag le ho khomarela.
Selelekela:
Hydroxyethyl cellulose (HEC) ke polymer e sa qhibiliheng metsing e tsoang ho cellulose ka phetoho ea lik'hemik'hale. E sebelisoa haholo indastering e fapaneng joalo ka meriana, tlhokomelo ea botho, kaho le lipeipi ka lebaka la thepa ea eona e ikhethang. Sebakeng sa lipeipi, HEC e sebeletsa mesebetsi e mengata, ho kenyeletsoa ho teteana, ho tsitsisa le ho fana ka thepa ea ho etsa filimi. Sengoloa sena se shebane le ts'ebeliso ea HEC lipeiping 'me se hlahloba tšusumetso ea eona ts'ebetsong ea lipeipi.
Litšebeliso tsa HEC ho Liaparo:
Moemeli oa ho Tetefatsa:
HEC e sebetsa e le moemeli ea sebetsang hantle oa ho teteana mefuteng ea ho roala. Ka ho eketsa ho teteana ha tharollo ea ho roala, HEC e ntlafatsa botsitso ba mebala le lintho tse ling tse eketsang, e thibela ho lula kapa ho kopana ha lintho nakong ea polokelo le ts'ebeliso. Ho teteana ha lesela ho ka fetoloa ka ho fetola mahloriso a HEC, ho lumella hore metsoako e etselitsoeng ho fihlela litlhoko tse itseng tsa ts'ebeliso. Ho feta moo, HEC e fana ka boitšoaro ba pseudoplastic, ho bolelang hore e bontša ho teteana ho fokotsehileng tlas'a ho kuta, e leng se nolofalletsang ts'ebeliso e bonolo le ho leka-lekanya lesela.
Sefetoleli sa Rheology:
Ntle le ho teteana, HEC e sebetsa e le mofetoleli oa rheology mefuteng ea ho roala. E susumetsa boitšoaro ba phallo ea ho roala, e ntlafatsa litšobotsi tsa eona tsa ts'ebeliso tse kang ho hlahlathela, ho fafatsa, le ho koahela ka roller. HEC e fana ka boitšoaro ba ho fokotsa ho kuta ho roala, e lumellang ts'ebeliso e boreleli ha e ntse e boloka viscosity ha matla a ho kuta a tlosoa. Thepa ena e molemo haholo ho fokotsa ho fafatsa nakong ea ts'ebeliso ea ho fafatsa le ho netefatsa ho koaheloa ka mokhoa o ts'oanang holim'a li-substrate tse nang le liprofaele tse fapaneng tsa bokaholimo.
Filimi ea Pele:
HEC e thusa ho theheng filimi e tswelang pele le e ts'oanang hodima bokaholimo ba substrate. Ha lesela le oma, dimolek'hule tsa HEC di a kopana ho theha sebopeho sa filimi se kopaneng, se fanang ka kgomarelo e ntle ho substrate le ho ntlafatsa ho tshwarella ha lesela. Thepa ya HEC ya ho etsa filimi e bohlokwa bakeng sa ho fihlella dibopeho tse lakatsehang tsa lesela tse kang ho thatafala, ho tenyetseha le ho hanyetsa boemo ba lehodimo. Ho feta moo, difilimi tsa HEC di bontsha ho hanyetsa metsi hantle, e leng se etsang hore di lokele dikobo tse pepeseditsweng mongobo kapa dibaka tse mongobo o phahameng.
Tšusumetso ea HEC Tshebetsong ea ho Koahela:
Taolo ea ho tsikinyeha:
HEC e nolofalletsa taolo e nepahetseng holim'a ho teteana ha lipekere, e netefatsa hore phallo e ntle le litšobotsi tsa ho leka-lekana li thibela mathata a kang ho thekesela, ho rotha ha metsi, kapa ho se lekane ha ho sebelisoa, e leng se lebisang ho boleng bo ntlafetseng ba ho teteana le botle. Ho feta moo, boitšoaro ba ho fokotsa ho kuta ha HEC bo nolofalletsa tšebeliso e bonolo ntle le ho beha ts'ebetso ea ho teteana kotsing.
Ho Hanyetsa le ho Lekanya le ho Sag:
Matlotlo a rheological a fanoang ke HEC a tlatsetsa ho haneleng le ho thella ho hoholo ha dikobo. Nakong ya tshebediso, HEC e fokotsa tshekamelo ya kobo ho etsa matshwao a borashe kapa di-roller stipple, e leng se fellang ka qetello e boreledi le e tshwanang. Ho feta moo, HEC e ntlafatsa boitshwaro ba thixotropic ba dikobo, e thibela ho thella kapa ho rotha hodima bokahodimo bo otlolohileng, ka hona e ntlafatsa bokgoni ba tshebediso le ho fokotsa tshenyo ya thepa.
Ho khomarela:
HEC e ntlafatsa ho khomarela ha lipekere ho li-substrate tse fapaneng, ho kenyeletsoa le litšepe, lehong, polasetiki le konkreite. Litšobotsi tsa HEC tse etsang filimi li theha maqhama a matla pakeng tsa pekere le substrate, e leng se ntlafatsang ho khomarela le ho tšoarella ha nako e telele. Sena se bohlokoa haholo ho lipekere tsa kantle tse pepeselitsoeng maemong a thata a tikoloho, moo ho khomarela ho bapalang karolo ea bohlokoa ho thibeleng ho hloleha ha pekere joalo ka ho petsoha kapa ho qhaqhoa.
Tsoelo-pele Theknolojing ea HEC:
Tsoelo-pele ea morao tjena hoHECtheknoloji e lebisitse ntshetsopeleng ya di-derivatives tsa HEC tse fetotsweng tse nang le dibopeho tse ntlafetseng tsa tshebetso. Diphetoho tsena di kenyeletsa diphetoho boima ba dimolek'hule, tekanyo ya ho nkela sebaka, le sebopeho sa dikhemikhale, e leng se dumellang ditharollo tse ikgethileng ho fihlela ditlhoko tse ikgethang tsa tshebediso. Ho feta moo, resea
Maiteko a rch a shebane le ho ntlafatsa botsitso ba tikoloho ba lits'ebetso tsa tlhahiso ea HEC, e leng se lebisitseng ho hlaheng ha HEC e thehiloeng linthong tse phelang e nkiloeng mehloling e nchafatsoang joalo ka cellulose ho tsoa ho biomass ea limela.
Mekhoa e Hlahang ea Ts'ebeliso ea HEC ho Liaparo:
Metswako e Sireletsang Tikoloho:
Ka ho totobatsa melaoana ea botsitso le tikoloho e ntseng e eketseha, ho na le tlhoko e ntseng e hola ea mekhoa ea ho koahela e sebelisang lintho tse eketsang tikoloho tse kang HEC. HEC e thehiloeng ho bio e tsoang mehloling e nchafatsoang e fana ka mokhoa o mong o tsitsitseng oa ho sebelisa li-polymer tse thehiloeng ho peterole, e leng se fokotsang khatello ea khabone le tšusumetso ea tikoloho.
Liaparo tse Phahameng tsa Ts'ebetso:
Tlhoko ea liphahlo tse sebetsang hantle tse tšoarellang hantle, tse hanyetsang boemo ba leholimo le thepa ea botle e susumetsa ho amoheloa ha li-additives tse tsoetseng pele joalo ka HEC. Baqapi ba ntse ba hlahloba mekhoa e mecha ea ho ntlafatsa ts'ebetso ea liphahlo ba sebelisa mekhoa e thehiloeng ho HEC, e sebeletsang lits'ebetsong tse fapaneng ho tloha ho pente ea meralo ho isa ho liphahlo tsa likoloi.
Mahlale a ho Koahela a Dijithale:
Tsoelo-pele mahlaleng a ho koahela a dijithale, joalo ka khatiso ea inkjet le ho bapisa mebala ea dijithale, e fana ka menyetla e mecha ea ts'ebeliso ea HEC ho li-coat. Mekhoa e thehiloeng ho HEC e ka ntlafatsoa bakeng sa ho lumellana le lits'ebetso tsa khatiso ea dijithale, e nolofalletsang taolo e nepahetseng holim'a thepa ea ho koahela le ho ntlafatsa boleng ba khatiso le ho nepahala ha 'mala.
Hydroxyethyl cellulose (HEC)e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea lipehelo ka ho sebetsa e le setenya, modifier ea rheology, le foreime ea filimi. Thepa ea eona e ikhethang e nolofalletsa taolo e nepahetseng holim'a viscosity, ho leka-lekana ho hoholo, ho hanyetsa ho oa, le ho khomarela ka mokhoa o phahameng ho li-substrate. Tsoelo-pele ea morao tjena theknolojing ea HEC le mekhoa e hlahang ts'ebelisong ea eona e totobatsa bohlokoa ba eona e le tlatsetso e feto-fetohang mefuteng ea lipehelo. Ha indasteri ea lipehelo e ntse e tsoela pele ho fetoha, HEC e ikemiselitse ho lula e le karolo ea bohlokoa nts'etsopele ea litharollo tsa lipehelo tsa boleng bo holimo le tse tšoarellang.
