HPMC Hydroxypropyl Tile Adhesive Cement Mix
Hydroxypropyl methylcellulose, eo hape e tsejoang e le HPMC, ke motsoako oa selulose o sebelisoang hangata indastering ea kaho, haholo tlhahisong ea likhomaretsi tsa lithaele le metsoako ea samente. Ke sehlahisoa se feto-fetohang se ka sebelisoang lits'ebetsong tse fapaneng tse fapaneng mme se fana ka melemo e mengata e etsang hore e be motsoako o loketseng mefuta e mengata e fapaneng ea thepa ea moaho.
E 'ngoe ea melemo e ka sehloohong ea HPMC ke bokhoni ba eona ba ho ntlafatsa ts'ebetso le botsitso ba metsoako ea samente le sekhomaretsi sa lithaele. Ha e eketsoa ho lisebelisoa tsena, HPMC e sebetsa e le motenya, e thusa ho eketsa viscosity ea motsoako le ho etsa hore ho be bonolo ho sebetsa le eona. Sena se bohlokoa haholo bakeng sa mesebetsi ea lithaele e hlokang tšebeliso e boreleli, e tsitsitseng ea sekhomaretsi ho netefatsa pheletso ea boleng bo holimo.
Ntle le ho ntlafatsa ts'ebetso, HPMC e ka eketsa matla le ho tšoarella ha metsoako ea samente le sekhomaretsi sa lithaele. Ka ho theha maqhama a matla pakeng tsa sekhomaretsi le sekhomaretsi, HPMC e ka thusa ho thibela tile hore e se ke ea lokoloha kapa e fetoha ha nako e ntse e feta, e ka thusang ho lelefatsa bophelo ba ho kenya le ho fokotsa tlhokahalo ea ho lokisoa nakong e tlang.

Melemo ea HPMC Hydroxypropyl Tile Bonding Cement Mix:
1. Ntlafatsa ts'ebetso:
E 'ngoe ea melemo ea mantlha ea ho sebelisa HPMC ka likhomaretsi tsa lithaele le metsoako ea cementitious ke hore e ntlafatsa ts'ebetso le botsitso. HPMC e sebetsa e le motenya oa thepa ena, e thusa ho eketsa viscosity ea bona le ho etsa hore ho be bonolo ho sebetsa le eona. Sena se bohlokoa haholo bakeng sa merero ea lithaele moo ts'ebeliso ea sekhomaretsi e boreleli, e tsitsitseng e leng bohlokoa ho netefatsa pheletso ea boleng bo holimo.
2. Matla a eketsehileng le ho tšoarella:
Ntle le ho ntlafatsa ts'ebetso, HPMC e boetse e thusa ho ntlafatsa matla le ho tšoarella ha likhomaretsi tsa lithaele le metsoako ea cementitious. Ka ho theha maqhama a matla pakeng tsa sekhomaretsi le sekhomaretsi, HPMC e ka thusa ho thibela tile hore e se ke ea lokoloha kapa e fetoha ha nako e ntse e feta, e ka thusang ho lelefatsa bophelo ba ho kenya le ho fokotsa tlhokahalo ea ho lokisoa nakong e tlang.
3. Ho boloka metsi:
Molemo o mong o moholo oa ho sebelisa HPMC ka likhomaretsi tsa lithaele le metsoako ea cementitious ke bokhoni ba eona ba ho boloka metsi. Ka ho ts'oara mongobo ka har'a motsoako, HPMC e ka thusa ho thibela motsoako hore o se ke oa omella ka potlako, e leng ntho ea bohlokoa ka ho khetheha libakeng tse chesang kapa tse mongobo.

Ha e na chefo, ha e tenehe ebile ha e ntše mosi leha e le ofe o kotsi kapa lik'hemik'hale nakong ea tšebeliso. Sena se etsa hore e be se loketseng bakeng sa lihahi le borakonteraka ba batlang lihlahisoa tsa boleng bo holimo, tse bolokehileng le tse sebetsang hantle bakeng sa merero ea bona ea kaho.
HPMC ke sehlahisoa se feto-fetohang le se sebetsang se sebelisoang haholo indastering ea kaho, haholo-holo tlhahisong ea likhomaretsi tsa lithaele le metsoako ea samente. Bokhoni ba eona ba ho ntlafatsa ts'ebetso, ho eketsa matla le ho tšoarella, ho boloka metsi, ho hanela ho honyela, le ho sireletseha le ho baballa tikoloho ho etsa hore e be motsoako o loketseng mefuta e mengata e fapaneng ea thepa ea moaho.
Haeba u sehahi, rakonteraka kapa motho ea chesehelang DIY ea batlang lihlahisoa tsa boleng bo holimo, tse tšepahalang ho u thusa ho fihlela lipheo tsa hau tsa kaho, nahana ka ho sebelisa HPMC ka likhomaretsi tsa lithaele le metsoako ea samente. Ka mefuta e mengata ea melemo le rekoto e netefalitsoeng ea katleho, ke khetho e ntle haholo e tla fana ka liphetho tseo u li hlokang.
