Seretse se ommeng ke phofo e phethiloeng e entsoeng ka thepa e ommeng ea samente, li-aggregate, li-filler, le li-additives tse fapaneng tse sebetsang ka tekanyo e loketseng fekthering. Nakong ea kaho, e ka sebelisoa feela ka ho eketsa metsi le ho hlohlelletsa. Ho fihlela litlhoko tse fapaneng tsa ts'ebetso ea kaho le ho tšoarella, seretse se ommeng hangata se hloka ho eketsoa ha li-additives tse ngata, tseo ho tsona li-ether tsa cellulose e leng e 'ngoe ea li-additives tsa bohlokoa ka ho fetisisa tsa polymer tsa tlhaho.
1. Tlhophiso ea Lisebelisoa tse Tloaelehileng bakeng sa Seretse se Motsoako o Omileng
1.1. Dintho tse Thibetsang ho Boloka Metsi
Mehlala e tloaelehileng e kenyelletsahydroxypropyl methylcellulose (HPMC),hydroxyethyl methylcellulose (HEMC)lehydroxyethyl cellulose (HEC).
Mesebetsi e ka Sehloohong: Ho ntlafatsa ho boloka metsi ka seretse, ho thibela ho tsoa mali, ho eketsa nako ea ho bula, le ho ntlafatsa botsitso le thixotropy nakong ea kaho.
1.2. Li-Retarder le Li-Accelerator
Di-retarders (tse kang citric acid le tartaric acid) di diehisa ho bewa ha tsona mme di loketse ho bewa ha mocheso o phahameng kapa ditshebediso tse kgolo. Di-accelerator (tse kang chloride salts le aluminium salts) di potlakisa ho bewa le ho tiya ha mocheso o tlase.
1.3. Lisebelisoa tsa ho Koetlisetsa Moea
Li-sulfonate tsa lignin le li-sulfonate tsa alkyl tse sebelisoang hangata ke tsona. Li ntlafatsa ho sebetsa ha seretse, ho hanyetsa serame, le ho phalla ha metsi ka ho hlahisa lipululana tse tšesaane.
1.4. Disebediswa tse Fokotsang Metsi
Haholo-holo metsoako e thehiloeng ho naphthalene le polycarboxylic acid, e fokotsa tšebeliso ea metsi le ho ntlafatsa matla le ho teteana ha seretse.
1.5. Phofo ea Polymer e ka Nchafatsoang (RDP)
E ntlafatsa ho tenyetseha ha seretse, ho khomarela le ho hanyetsa mapetso. E sebelisoa hangata ho likhomaretsi tsa thaele, litsamaiso tsa ho thibela lebota ka ntle, le ho lokisa li-mort.
1.6. Lisebelisoa tse ling tse sebetsang
E kenyelletsa lithibela-mouta, lintho tse thibelang metsi, phofo e sa rateng metsi, le li-starch ether tse teteaneng. Lintho tsena tse eketsang li khethoa ho latela tšebeliso e reriloeng ea seretse.
2. Mokhoa oa Ketso ea Cellulose Ethers ka har'a Li-mortar tse Omileng
Li-ether tsa cellulose ke sehlopha sa li-polymer tse seng tsa ionic tse qhibilihang metsing tse sebelisoang haholo lits'ebetsong tse fapaneng tsa seretse se kopantsoeng ka omileng. Mekhoa ea eona e meholo ea ts'ebetso e kenyelletsa:
2.1. Ho Boloka Metsi
Limolek'hule tsa ether tsa cellulose li monya le ho notlela metsing a tsoakiloeng, li liehisa tahlehelo ea tsona ho substrate le moeeng, li netefatsa nako e lekaneng ea metsi bakeng sa thepa e etsang samente, ka hona li ntlafatsa matla a seretse.
2.2. Taolo ea ho Tetefala le Rheology
Li-ether tsa cellulose li etsa tharollo e tiileng ka metsing, e ntlafatsang botsitso bo metsi le ho khomarela ha seretse, e leng se etsang hore se se ke sa thella habonolo (ho hanyetsa ho salla) nakong ea tšebeliso holim'a libaka tse otlolohileng. Ho feta moo, li-ether tsa cellulose tsa boleng bo holimo li bontša thixotropy e ntle haholo, e leng se thusang ho boreletsa le ho lokisa calender.
2.3. Bokhoni bo Ntlafetseng ba ho Sebetsa
Tšusumetso e kopanetsoeng ea ho boloka metsi le thepa ea rheological e netefatsa nako e telele e sebetsang le ho ikutloa hantle ha seretse, e fokotsa mokhathala nakong ea ts'ebeliso.
2.4. Botsitso bo Ntlafetseng
Ho fokotsa karohano le ho tsoa mali ha lintho tse kopantsoeng le thepa e etsang samente ho ntlafatsa ho tšoana ha seretse le botsitso ba boleng ba kaho.
3. Tšebeliso ea Cellulose Ethers ka har'a li-mortar tse fapaneng tse omileng
3.1. Seretse sa Majoe le Seretse sa Plaster
Ho hlokahala ho boloka metsi a mangata le ho sebetsa hantle. Li-ether tsa cellulose li ka fokotsa ho petsoha le ho petsoha, 'me tsa ntlafatsa ho khomarela.
3.2. Sekhomaretsi sa Taele
Ho hlokahala thepa e ntle haholo ea ho thibela ho oa le nako e telele e bulehileng. Li-ether tsa cellulose li etsa bonnete ba hore lithaele ha li thelle kamora ho sebelisoa 'me li lumella nako e lekaneng ea ho lokisa.
3.3. Seretse se Itekanetseng
Ho hlokahala mokelikeli o phahameng le botsitso. Khetha ether ea cellulose e nang le viscosity e tlase le ho boloka metsi a mangata ho qoba ho tsoa mali le ho arohana.
3.4. Sistimi ea ho Sireletsa ea Kantle (EIFS) Seretse
Ho boloka metsi ho ama ka ho toba ho khomarelana pakeng tsa boto ea ho thibela le seretse. Li-ether tsa cellulose li ka netefatsa boleng bo tsitsitseng nakong ea ts'ebeliso e kholo.
4. Litlhokomelo tsa Khetho le ho Eketsa
Khetho ea Viscosity: Viscosity e phahameng e fana ka ho boloka metsi a mangata empa e ka fokotsa ho sebetsa; viscosity e tlase e fana ka mokelikeli o motle empa e na le tšekamelo ea ho tsoa mali. Liphetoho li lokela ho etsoa ho latela mokhoa o itseng. Palo ea tlatsetso: Hangata 0.1% ho isa ho 0.5% ea boima ba thepa e etsang samente. Ho eketsa ho feteletseng ho ka ama matla le nako ea ho omisa.
Ho qhalana: Ho qhalana ka botlalo hoa hlokahala nakong ea ho kopanya ka omileng ho thibela ho kopana ha mahlaka ka mor'a ho eketsa metsi.
Ho ntlafatsa tshebetso ya seretse se ommeng ho hloka sistimi e ntle ya ho eketsa, leether ea seluloseke mofetoleli oa mantlha ka har'a sistimi ena. Ha e netefatse feela hore seretse se boloka metsi le ho sebetsa ha sona, empa hape e susumetsa ka tsela e sa tobang matla a tlamo, ho tšoarella, le boleng ba bokaholimo. Ka litlhoko tse ntseng li eketseha tsa kaho le ho amoheloa ho pharaletseng ha likhopolo tse bolokang matla le tse sireletsang tikoloho, ts'ebeliso ea ether ea cellulose ka seretseng se ommeng e tla ba e fapaneng le e ntlafalitsoeng haholoanyane.
