Ka ntlafatso ea tlhokomeliso ea tikoloho le litlhoko tse ntseng li eketseha tsa 'maraka oa thepa ea mohaho bakeng sa ts'ebetso le ts'ireletso ea tikoloho, thepa ea mohaho e sa sireletsehang ea tikoloho butle-butle e fetohile lihlahisoa tse tloaelehileng tšimong ea kaho. Cellulose ether, e le thepa ea polymer e sebetsang ka bongata, e phetha karolo ea bohlokoa ho thepa ea mohaho e nang le botsoalle ba tikoloho ka ts'ebetso ea eona e babatsehang. Ho na le mefuta e mengata ea li-cellulose ethers, tse tloaelehileng ka ho fetisisa ke hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), hydroxyethyl cellulose (HEC), joalo-joalo Li sebelisoa haholo-holo ka thepa ea mohaho ea tikoloho e kang li-adhesives, putty powder. , seretse se omeletseng le liphahlo ka ho laola hydration, ho ntlafatsa rheology le ho ntlafatsa thepa ea thepa.
1. Litšobotsi tsa li-cellulose ethers
Cellulose ether ke motsoako oa polymer o ntšitsoeng likhoeleng tsa tlhaho tsa semela. E entsoe ka ho qhibiliha, ho teteaneng, ho boloka metsi le ho etsa filimi ka karabelo ea etherification. Litšobotsi tsa eona tse ka sehloohong li kenyelletsa:
Ho boloka metsi: Cellulose ether e na le bokhoni bo botle ba ho boloka metsi, bo ka laolang ka katleho ho lokolloa ha metsi ka thepa ea mohaho, ho qoba ho fetoha mouoane ho feteletseng ha metsi, 'me kahoo ho ntlafatsa ts'ebetso ea kaho.
Thickening: Cellulose ether e atisa ho sebelisoa e le motenya oa thepa ea mohaho, e ka ntlafatsang viscosity ea thepa le ho ntlafatsa ts'ebetso ea eona nakong ea kaho.
Adhesion: Ka seretse se omeletseng se kopantsoeng le li-adhesives, cellulose ether e ka sebelisoa e le setlamo ho matlafatsa ho khomarela pakeng tsa thepa le motheo.
Phetoho ea Rheological: Cellulose ether e ka ntlafatsa thepa ea rheological ea thepa ea mohaho, e le hore ba ka boloka metsi a matle le thixotropy tlas'a maemo a fapaneng a kaho, a loketseng bakeng sa ho haha le ho bōpa.
Anti-sagging: Cellulose ether e ka ntlafatsa thepa e thibelang ho sisinyeha ha thepa, haholo-holo ha ho etsoa mabota a emeng, a ka thibelang seretse kapa pente hore e senyehe.
2. Ho sebelisoa ha cellulose ether linthong tsa mohaho tse sa silafatsang tikoloho
Seretse se omileng se kopantsoeng
Seretse se kopantseng se omileng ke thepa ea kaho e tloaelehileng e baballang tikoloho, haholo-holo e sebelisoang ho rala mabota, ho beha fatše, ho beha lithaele le litšoantšo tse ling. Cellulose ether e sebelisoa haholo ka seretse se omileng se omileng, haholo-holo se bapala karolo ea ho boloka metsi, ho tiisa le ho kopanya. Cellulose ether e ka etsa hore seretse se lokolle metsi ka mokhoa o ts'oanang nakong ea ho omisa, ho thibela mapetsong a bakoang ke tahlehelo e feteletseng ea metsi, le ho matlafatsa matla a tlamahano ea seretse ho netefatsa matla a sona le ho tšoarella ka mor'a ho hahoa.
Liaparo tsa meralo
Cellulose ether e sebelisoa e le setsi se teteaneng le se bolokang metsi ka har'a liphahlo tsa meralo tse thehiloeng metsing ho ntlafatsa ts'ebetso ea kaho le phello ea ho qetela ea ho roala. E na le thepa e babatsehang ea ho etsa lifilimi le ho fetola rheological, e ka netefatsang hore seaparo se na le ho hasana hantle tlas'a lisebelisoa tse fapaneng tsa ho haha. Ho phaella moo, cellulose ether e ka boela ea ntlafatsa thepa e khahlanong le ho senya ea ho roala, ho etsa hore ho se ke ha e-ba bonolo hore e fokotsehe ha e sebelisoa holim'a libaka tse otlolohileng, kahoo e fumana seaparo se tšoanang.
Likhomaretsi tsa lithaele
Li-adhesives tsa lithaele ke ts'ebeliso ea bohlokoa tšimong ea lisebelisoa tsa mohaho tse nang le tikoloho. Li-cellulose ethers li ka ntlafatsa ho boloka metsi le thepa e thibelang ho thella ea likhomaretsi le ho matlafatsa matla a maqhama pakeng tsa lithaele le lera la motheo. Nakong ea kaho, ho eketsoa ha cellulose ethers ho ntlafatsa haholo ts'ebetso ea li-adhesives tsa lithaele, ha ho ntse ho netefatsa nako e telele e bulehileng, e loketseng hore basebetsi ba kaho ba ka e lokisa.
Putty phofo
Putty phofo e sebelisetsoa ho lokisa le ho lokisa lebota. Ho boloka metsi a cellulose ether ho ka thibela ho phatloha kapa ho oa ho bakoang ke ho omella ha putty kapele ka mor'a hore ho hahoe. Ka nako e ts'oanang, thepa ea eona e teteaneng e thusa ho ntlafatsa ho roala le ho boreleli ha putty, ho etsa hore mohaho o be bonolo.
Lisebelisoa tsa fatše tse ikemetseng
Tšebeliso ea cellulose ether ka thepa ea fatše e ikemetseng ke haholo-holo ho ntlafatsa mokelikeli oa eona le ho boloka metsi, ho etsa bonnete ba hore thepa e ka tsamaisoa ka potlako le ka ho lekana nakong ea kaho ea fatše, le ho thibela fatše ho phunyeha kapa lehlabathe le bakoang ke tahlehelo ea metsi.
3. Melemo ea tikoloho ea cellulose ether
Mohloli oa tlhaho, tlhahiso ea tikoloho
Cellulose ether e entsoe ka selulose ea tlhaho 'me e ka nchafatsoa. Ha ho na khase e kotsi ea litšila le mokelikeli o litšila tse hlahisoang nakong ea tlhahiso, 'me phello ea tikoloho e nyane. Ho phaella moo, ha e bapisoa le metsoako e tloaelehileng ea lik’hemik’hale, cellulose ether ha e kotsi ’meleng oa motho ’me ka tlhaho e ka senyeha. Ke lintho tse tala e le kannete le tikoloho ea botsoalle.
Fokotsa tšebeliso ea matla a thepa le ho ntlafatsa katleho ea kaho
Cellulose ether e ka ntlafatsa ts'ebetso ea kaho ea thepa ea moaho, ea etsa hore kaho ea bona e be bonolo le ho potlaka, le ho fokotsa litšila le tšebeliso ea matla. Ho phaella moo, ka lebaka la ho boloka metsi hantle, cellulose ether e ka fokotsa tlhokahalo ea metsi kahong le ho boloka mehloli.
Ntlafatsa ho tšoarella ha thepa ea kaho
Cellulose ether e ka ntlafatsa ho tšoarella ha thepa ea mohaho e sa sireletsehang tikolohong, ea etsa hore bophelo ba tšebeletso ea mehaho e be telele, e fokotsa tlhokahalo ea ho lokisoa kapa ho nkeloa sebaka ka lebaka la botsofali kapa tšenyo ea thepa ea mohaho, kahoo e fokotsa litšila tsa lisebelisoa le ho hlahisa litšila tsa kaho.
E le tlatsetso ea thepa ea kaho e baballang tikoloho, e bolokehileng le e sebetsang hantle, cellulose ether e 'nile ea sebelisoa haholo masimong a mangata a thepa ea kaho a se nang tikoloho joalo ka seretse se omeletseng, sekhomaretsi sa lithaele le liphahlo tsa meralo. E ke ke ea ntlafatsa feela ts'ebetso ea kaho ea thepa ea kaho le ho ntlafatsa boleng ba thepa, empa hape e na le melemo ea bohlokoa ea tikoloho. Tšimong ea nakong e tlang ea thepa ea mohaho, ka ntlafatso e tsoelang pele ea litlhoko tsa tšireletso ea tikoloho, menyetla ea kopo ea cellulose ether e tla ba e pharaletseng.
