Cellulose ether ke motsoako oa manyolo o nang le ts'ebetso e ntle haholo, e sebelisoang haholo tšimong ea thepa ea mohaho, haholo-holo ha ho etsoa mokhoa oa ho lokisa lerako la putty le putty ea ka hare le ka ntle. E ke ke ea ntlafatsa feela ts'ebetso ea kaho ea putty, empa hape e ntlafatsa ho tšoarella le matla a putty kamora kopo.
1. Kakaretso ea cellulose ether
Cellulose ether ke sehlopha sa metsoako ea polymer e qhibilihang ka metsing kapa e qhalakang ka metsi e entsoeng ka phetoho ea lik'hemik'hale e thehiloeng ho cellulose ea tlhaho. Li-cellulose ethers tse tloaelehileng li kenyelletsa hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), joalo-joalo. Li-ethers tsena tsa cellulose li na le li-thickening tse ntle, ho boloka metsi, lubrication, filimi-forming le lisebelisoa tse ling, kahoo li sebelisoa haholo ho haha. lisebelisoa.
2. Karolo ea cellulose ether ka putty
Ntlafatsa ts'ebetso ea kaho ea putty
Cellulose ether e ntlafatsa thepa ea rheological ea putty, e le hore ho sebetsa le ho lekanngoa ha thepa ea putty ho ka ntlafatsoa, ho etsa hore ho be bonolo ho e sebelisa le boemo. Haholo-holo mohahong o moholo, thepa e teteaneng ea cellulose ether e ka etsa hore putty e khomarele lebota, e fokotsa ho fokotseha, le ho netefatsa botsitso ba boleng ba kaho.
Ntlafatsa ho boloka metsi
Lera la putty le hloka ho boloka boemo bo itseng ba metsi nakong ea ts'ebetso ea kaho ho netefatsa ho ts'oana le ho khomarela mokhoa o latelang oa ho omisa. Limolek'hule tsa cellulose ether li ka monya metsi a mangata 'me tsa etsa marang-rang a molek'hule ea metsi ka har'a putty, e fokotsa sekhahla sa mouoane oa metsi a putty, kahoo e ntlafatsa haholo ho boloka metsi a putty. Ho boloka metsi hona ho etsa hore putty e se be le monyetla oa ho peperana kapa phofo ha e hahiloe tlasa mocheso o phahameng kapa maemo a omileng, ho lelefatsa nako e bulehileng ea kaho le ho netefatsa boleng ba putty layer.
Matlafatsa matla a maqhama
Ho eketsa litaba tsa cellulose ether ho ka ntlafatsa ho khomarela ha putty le ho etsa bonnete ba hore putty e khomaretsoe ka thata holim'a setsi. Ha putty e sebelisoa, ether ea cellulose e ke ke ea ntlafatsa feela ho tiea ha putty, empa hape e fana ka tekanyo e itseng ea ho khomarela nakong ea ts'ebetso ea ho omisa ho thibela putty layer hore e se ke ea oa kapa ea sotheha. Sena ke sa bohlokoa ka ho khetheha bakeng sa libaka tse boreleli le metheo e sa monyeng hobane cellulose ether e fana ka thepa e eketsehileng ea ho khomarela.
Laola lebelo la ho omisa
Cellulose ether e ka fetola lebelo la ho omisa la putty e le hore lesela la putty le ka omella ka mokhoa o ts'oanang, ka tsela eo ho thibela ho phatloha ho bakoang ke tahlehelo e potlakileng ea metsi holim'a metsi. Bakeng sa kaho ea li-putty tse ngata, lebelo le loketseng la ho omisa le bohlokoa ka ho khetheha, le thusang ho tiisa hore ho khomarela pakeng tsa lihlopha le phello e akaretsang.
Ntlafatsa ts'ebetso ea anti-sagging
Maboteng a emeng kapa siling, putty e angoa habonolo ke matla a khoheli mme e na le mathata a ho thella le ho thella. Tšusumetso e matla ea cellulose ether e ka ntlafatsa ka katleho viscosity le botsitso ba putty, ea thibela thepa hore e se ke ea thella ka lebaka la matla a khoheli, 'me e netefatse kabo e tšoanang ea putty.
3. Mefuta e ka sehloohong le khetho ea cellulose ethers
Mefuta e fapaneng ea ethers ea cellulose e na le liphello tse fapaneng ka putty, 'me ke habohlokoa haholo ho khetha mofuta o nepahetseng oa cellulose ether. Tse latelang ke tse 'maloa tse sebelisoang hangata cellulose ether le litšobotsi tsa tsona:
Hydroxypropyl methylcellulose (HPMC): E na le botenya bo botle, ho boloka metsi le thepa ea ho etsa filimi 'me e sebelisoa haholo ho haha putty. HPMC e ka ntlafatsa haholo kaho le thepa ea ho etsa filimi ea putty, ea etsa hore putty e be boreleli ha e sebelisoa, 'me ea ntlafatsa ho khomarela le ho boreleli ha putty.
Hydroxyethyl cellulose (HEC): E sebelisoa haholo-holo lits'ebetsong tse thehiloeng metsing, e na le bokhoni bo botle ba ho tiea le ho laola rheology, 'me hangata e sebelisoa ka har'a lebota la ka hare le liphahlo tse thehiloeng metsing. HEC e na le phello e kholo ea ntlafatso ho boemo ba ho roala ha putty, empa ho boloka metsi ho tlase hanyane ho feta HPMC.
Hydroxypropyl cellulose (HPC): HPC e na le viscosity e phahameng le botsitso bo babatsehang, 'me e loketse liketsahalo tse nang le litlhoko tse phahameng tsa anti-sagging. Ho kenyelletsa palo e nepahetseng ea HPC ho putty ho ka ntlafatsa haholo ts'ebetso ea anti-sagging le matla a putty.
4. Melemo ea kopo le litebello tsa 'maraka tsa cellulose ethers
Melemo ea ts'ebeliso ea cellulose ethers ka putty e bohlokoa, haholo e bonts'oa likarolo tse latelang:
Ho boloka litšenyehelo: Li-cellulose ethers li ka ntlafatsa ts'ebetso ea putty ka katleho, tsa fokotsa palo ea li-reworks, kahoo tsa fokotsa litšenyehelo tsa thepa le tsa basebetsi.
Tšireletso ea tikoloho: Li-cellulose ethers ke lisebelisoa tsa tlhaho tse entsoeng ka lisebelisoa tse tsosolositsoeng, tse nang le tšireletso e ntle ea tikoloho, tse se nang chefo 'meleng oa motho,' me li thusa ho finyella litlhoko tsa thepa ea kajeno ea mohaho bakeng sa tšireletso ea tikoloho e tala.
Ho ikamahanya le maemo a leholimo a fapa-fapaneng: Ho boloka metsi le ho hanyetsa crack ea cellulose ethers ho etsa hore e tšoanelehe bakeng sa kaho tlas'a maemo a fapaneng a leholimo, ho finyella litlhoko tsa libaka tse fapaneng tsa kaho tse kang leboea le mongobo o ka boroa.
Litebello tse ntle tsa 'maraka: Ka nts'etsopele ea meaho e tala le tlhokahalo e ntseng e eketseha ea thepa ea kaho e sebetsang hantle, tlhoko ea' maraka ea li-cellulose ethers joalo ka litlatsetso tsa bohlokoa e eketsehile selemo le selemo. Haholo-holo indastering ea mokhabiso, litlhoko tsa ho pata marako le botle ba holim'a metsi li ntlafalitsoe, tse atolositseng sebaka sa nts'etsopele ea lihlahisoa tsa putty. Cellulose ether joalo ka phetoho e tla ba le menyetla e mengata ea ts'ebeliso.
5. Litlhokomelo bakeng sa ether ea cellulose ka tšebeliso ea putty
Leha cellulose ether e na le melemo e mengata ho putty, lintlha tse latelang li lokela ho hlokomeloa ts'ebetsong ea 'nete ea kopo:
Taolo ea litekanyetso: Keketso e feteletseng ea cellulose ether e tla lebisa ho viscosity e feteletseng ea putty le ho ama boemo ba kaho. Ka hona, palo ea cellulose ether e kentsoeng ka foromo ea putty e hloka ho laoloa ka mokhoa o utloahalang ho netefatsa ts'ebetso e ntle ka ho fetisisa ea kaho.
Phatlalatso e tšoanang: Ho hasana ha cellulose ether ka putty ho tla ama phello ea eona ka kotloloho. E le ho qoba ho kopana ha cellulose ether, hoa hlokahala ho sebelisa mekhoa e nepahetseng ea ho susumetsa ha u lokisetsa putty ho etsa bonnete ba hore e hasane ka tsela e lekanang karolong ea metsi.
Ho lumellana le li-additives tse ling: Hangata liforomo tsa putty li na le li-additives tse ling, tse kang redispersible latex powder, fillers, joalo-joalo. Ho lumellana ha cellulose ether le li-additives tsena ho tla ama ts'ebetso ea putty ka ho toba, kahoo tšebelisano pakeng tsa metsoako e fapaneng e lokela ho nkoa ka botlalo ha ho etsoa moralo. foromo.
Tšebeliso ea cellulose ether leboteng la putty le putty ha e ntlafatse feela ts'ebetso ea kaho le ts'ebeliso ea putty, empa hape e eketsa bophelo ba tšebeletso ea putty le ho fokotsa mathata a boleng a bakoang ke kaho e sa lokelang. Ka ho atolosoa ho tsoelang pele ha 'maraka oa moaho o motala le thepa e khabisitsoeng, cellulose ether, e le tlatsetso e ntle ea tikoloho le e sebetsang hantle ea moaho, e na le tebello e pharaletseng ea ts'ebeliso. Moqaping oa foromo ea putty, khetho e nepahetseng le ts'ebeliso ea cellulose ether e ka fana ka ho bata le ho tšoarella ho hoholo bakeng sa ho haha marako, ka hona ho kopana le maemo a fapaneng a leholimo le litlhoko tsa kaho, le ho fana ka litiiso tse matla bakeng sa nts'etsopele ea boleng bo holimo ea meaho ea sejoale-joale.
