1. Kenyelletso ea hydroxyethyl methylcellulose
Hydroxyethyl Methyl Cellulose (HEMC)ke non-ionic metsi-qhibilihang selulose ether hlahisoa ka karabelo ea lik'hemik'hale tse kang alkalinization le etherification ea cellulose ea tlhaho. E na le botenya bo botle haholo, ho boloka metsi, ho etsa filimi, ho tlotsa le ho kopanya thepa 'me e sebelisoa haholo ho thepa ea kaho, liphahlo, meriana, lijo le masimo a mang. Sebakeng sa kaho, haholo-holo ka seretse se omileng le putty powder, HEMC e phetha karolo ea bohlokoa.
2. Karolo ea ho ntlafatsa ts'ebetso
Ntlafatsa tshebetso ya kaho
Har'a thepa ea moaho, HEMC e na le thepa e matla ea ho tenya mme e ka ntlafatsa ka katleho thixotropy le sag resistance ea thepa. Karolo ena e etsa hore kaho e be bonolo haholoanyane. Haholo-holo ha u sebelisa holim'a libaka tse otlolohileng, thepa ha e bonolo ho sisinyeha, e leng ho nolofalletsang basebetsi ho etsa seaparo se tšoanang le ho ntlafatsa katleho ea kaho.
rial e ka lula e loketse nako e telele ka mor'a hore e koahetsoe kapa e tsosoe. Sena se rekela basebetsi ba kaho nako e eketsehileng bakeng sa litokiso le litokiso le ho ntlafatsa boleng ba kaho.
3. Karolo ea ho ntlafatsa ts'ebetso
Lintho tse ntle tsa ho boloka metsi
E 'ngoe ea thepa e hlahelletseng ka ho fetesisa ea HEMC ke ho boloka metsi ka mokhoa o babatsehang. Ka seretse se entsoeng ka samente kapa sa gypsum, HEMC e ka fokotsa tahlehelo ea metsi ka katleho le ho etsa bonnete ba hore samente kapa gypsum e na le mongobo o lekaneng nakong ea karabelo ea hydration. Sena ha se ntlafatse feela matla le tlamahano ea thepa, empa hape se fokotsa kotsi ea mapetsong le sekoti.
Ntlafatsa ho khomarela
Kaha HEMC e na le thepa e ntle ea ho etsa lifilimi, e ka etsa filimi e ts'oanang holim'a mohaho oa kaho, kahoo e ntlafatsa ho khomarela pakeng tsa thepa le substrate. Thepa ena e bohlokoa ka ho khetheha lits'ebetsong tse kang li-adhesive tsa lithaele le li-putty, moo li ka ntlafatsang haholo ho tšoarella le botsitso.
Ntlafatsa khanyetso ea leqhoa
Libakeng tse batang haholo, ho hanyetsa ho qhibiliha ha thepa ho bohlokoa ka ho khetheha. HEMC e ntlafatsa ho hanyetsa boemo ba leholimo ba thepa ka ho ntlafatsa kabo ea mongobo ka har'a thepa le ho fokotsa liphetoho tsa molumo tse bakoang ke leqhoa le ho qhibiliha ha metsi nakong ea potoloho ea leqhoa.
4. Linyeoe tse tloaelehileng lits'ebetsong tse sebetsang
seretse se ommeng
Ka seretse se omeletseng, HEMC ha e ntlafatse feela ho boloka metsi le ho sebetsa ha seretse, empa e boetse e ntlafatsa ho sebetsa ha thepa, ho etsa hore seretse se be bonolo ho jala le ho bōptjoa nakong ea kaho.
Sekhomaretsi sa lithaele
HEMC e ka ntlafatsa matla a tlamahano ea colloid ka har'a likhomaretsi tsa lithaele tsa ceramic, ea netefatsa khokahano e tiileng lipakeng tsa lithaele tsa ceramic le li-substrates, le ho fokotsa ho thella ha thepa nakong ea kaho.
Putty phofo
Har'a li-putty powders, HEMC e ka ntlafatsa boreleli ba holim'a metsi, ea ntlafatsa ho hanyetsa metsi le ho hanyetsa ho phatloha ha ho roala, le ho etsa hore putty layer e sebetse hantle kahong e latelang (e kang pente ea latex).
Hydroxyethyl methylcellulose e se e le tlatsetso ea bohlokoa le ea bohlokoa ho thepa ea sejoale-joale ea moaho ka lebaka la botenya ba eona bo botle, ho boloka metsi, ho tlotsa le thepa e 'ngoe. Ha e ntlafatse haholo ts'ebetso ea lisebelisoa, empa hape e ntlafatsa ts'ebetso le ho tšoarella ha lihlahisoa tse felileng, e tlisang boiketlo bo boholo le melemo ho basebetsi ba kaho le basebelisi. Ka tsoelopele e tsoelang pele ea thekenoloji, libaka tsa kopo le litlamorao tsa HEMC li tla atolosoa, ho fana ka thuso e eketsehileng ntlafatsong ea indasteri ea kaho.
