Likhomaretsi tsa lithaele li bapala karolo ea bohlokoa indastering ea kaho, ho netefatsa maqhama a sireletsehileng a lithaele ho li-substrates tse fapaneng.Hydroxypropyl Methylcellulose (HPMC) ke motsoako o ka sehloohong oa likhomaretsi tse ngata tsa sejoale-joale, tse fanang ka lisebelisoa tse ntlafalitsoeng tsa sekhomaretsi le ho sebetsa.
1.Ho utloisisa Hydroxypropyl Methylcellulose (HPMC):
HPMC ke ntho e tsoang ho cellulose e sebelisoang hangata ho thepa ea kaho bakeng sa sekhomaretsi sa eona, ho tenya, le ho boloka metsi.
E tsoa ho selulose ea tlhaho 'me e etsoa phofo e ntle.
HPMC e matlafatsa matla a tlamahano ea likhomaretsi tsa lithaele ha e ntse e ntlafatsa ts'ebetso ea tsona le litšobotsi tsa ho boloka metsi.
2.Ho theha Sekhomaretsi sa Lithaele se thehiloeng ho HPMC:
a.Lisebelisoa tsa mantlha:
Samente ea Portland: E fana ka moemeli ea ka sehloohong ea tlamang.
Lehlabathe le letle kapa la ho tlatsa: Ho matlafatsa ts'ebetso le ho fokotsa ho honyela.
Metsi: A hlokeha bakeng sa hydration le ho sebetsa.
Hydroxypropyl Methylcellulose (HPMC): E sebetsa e le ntho e teteaneng le e kopanyang.
Li-additives: Li ka kenyelletsa li-modifiers tsa polymer, dispersants, le li-anti-sag agents bakeng sa lintlafatso tse khethehileng tsa ts'ebetso.
b.Karohano:
Karolo ea motsoako ka mong e fapana ho latela lintlha tse kang mofuta oa lithaele, substrate le maemo a tikoloho.
Sebopeho se tloaelehileng se ka 'na sa e-ba le 20-30% samente, 50-60% lehlabathe, 0.5-2% HPMC, le metsi a loketseng ho finyella botsitso bo lakatsehang.
c.Mokhoa oa ho kopanya:
Omisa kopanya samente, lehlabathe, le HPMC hantle ho netefatsa kabo e tšoanang.
Butle-butle eketsa metsi ha u ntse u kopanya ho fihlela ho finyelloa ho lumellana ho lakatsehang.
Kopanya ho fihlela peista e boreleli, e se nang kotola e fumanoa, ho netefatsa hore metsi a lekaneng a likaroloana tsa samente le ho hasana ha HPMC.
3.Tsebeliso ea Sekhomaretsi sa Lithaele se thehiloeng ho HPMC:
a.Tokiso ea Sebaka:
Netefatsa hore substrate e hloekile, e phetse hantle, 'me ha e na lerōle, mafura le litšila.
Libaka tse mahlahahlaha kapa tse sa leka-lekaneng li ka hloka hore li behoe kapa li hloekisoe pele ho sebelisoa sekhomaretsi.
b.Mekhoa ea Ts'ebeliso:
Tšebeliso ea trowel: Mokhoa o atileng haholo o kenyelletsa ho sebelisa trowel e notlelitsoeng ho ala sekhomaretsi holim'a substrate.
Back-buttering: Ho sebelisa lesela le tšesaane la sekhomaretsi ka morao ho lithaele pele u li beha ka betheng ea sekhomaretsi ho ka ntlafatsa maqhama, haholo-holo bakeng sa lithaele tse kholo kapa tse boima.
Spot Bonding: E loketse lithaele tse bobebe kapa lisebelisoa tsa mokhabiso, e kenyelletsa ho kenya sekhomaretsi ka likotoana tse nyane ho fapana le ho e hasanya ka har'a substrate eohle.
c.Kemiso ea Lithaele:
Tobetsa lithaele ka thata ka betheng ea sekhomaretsi, ho etsa bonnete ba hore ho kopana ho feletseng le ho koaheloa ka mokhoa o ts'oanang.
Sebelisa li-spacers ho boloka manonyeletso a grout a tsitsitseng.
Lokisa tekano ea lithaele kapele pele sekhomaretsi se seta.
d.Ho hloekisa le ho hloekisa:
Lumella sekhomaretsi hore se phekole ho latela litaelo tsa moetsi pele ho grouting.
Hlakola lithaele ho sebelisa thepa e loketseng ea grout, ho tlatsa manonyeletso ka ho feletseng le ho boreleli holim'a metsi.
4.Melemo ea Sekhomaretsi sa Lithaele tse thehiloeng ho HPMC:
Matla a Matlafalitsoeng a Bonding: HPMC e ntlafatsa ho khomarela lithaele le li-substrates ka bobeli, ho fokotsa kotsi ea ho thibela lithaele.
Ntlafatso ea Ts'ebetso e Ntlafetseng: Ho ba teng ha HPMC ho matlafatsa ts'ebetso le nako e bulehileng ea sekhomaretsi, e leng se lumellang hore ho be bonolo ho sebelisa le ho fetola lithaele.
Poloko ea Metsi: HPMC e thusa ho boloka mongobo ka har'a sekhomaretsi, ho khothaletsa hydration e nepahetseng ea samente le ho thibela ho omisa pele ho nako.
Sekhomaretsi sa lithaele se thehiloeng ho HPMC se fana ka tharollo e tšepahalang bakeng sa lits'ebetso tse fapaneng tsa ho kenya lithaele, e fana ka mamarello e matla, ts'ebetso e ntlafalitsoeng, le ho tšoarella ho matlafalitsoeng.Ka ho utloisisa mokhoa oa ho theha le oa ts'ebeliso o boletsoeng tataisong ena, litsebi tsa kaho li ka sebelisa likhomaretsi tsa HPMC ka nepo ho fihlela lits'ebetso tsa boleng bo holimo tsa lithaele.
