Umgangatho wolwakhiwo oluphezulu lwe-viscosity I-Hydroxypropyl Methylcellulose (HPMC) yokuncamathelisa iithayile yinxalenye ebalulekileyo yeeprojekthi zokwakha zale mihla, ngakumbi ukubophelela iithayile zeceramic kwimigangatho eyahlukeneyo. Le ngcina ilungiselelwe ukunika amandla aphezulu ebhondi, ukuguquguquka kunye nokuqina ngelixa kulula ukuyisebenzisa.
1. Ukwakheka kweekhemikhali kunye neempawu:
Ezona zithako ziphambili zokuncamathelisa ithayile kwibakala eliphezulu le-viscosity yeHPMC zezi:
IHydroxypropyl methylcellulose (HPMC): Le yipolymer ephambili emisela i-adhesive viscosity, amandla ebhondi, kunye nokuguquguquka.
Izihluzi kunye nezongezo: Ezi zithako zongeza iipropathi ezithile ezinje ngokugcinwa kwamanzi, ukusebenza, ukuncamathela kunye nexesha elivulekileyo.
Izihluzi zeminerali: njengesamente, isanti okanye ezinye iiaggregates ukunika amandla omatshini kunye nokuzinza.
2. Iimpawu kunye neenzuzo:
a. viscosity ephezulu:
I-viscosity ephezulu ye-adhesive iqinisekisa ukuxhathisa kwe-sag, ukuyivumela ukuba isetyenziswe kwiindawo ezithe nkqo ngaphandle kokutyibilika.
b. Amandla okudibanisa aphezulu:
Yenza ibhondi eyomeleleyo kunye neentlobo ezahlukeneyo ze-substrates ezibandakanya ikhonkrithi, i-masonry, i-plaster, ibhodi yesamente kunye neethayile ezikhoyo.
Iqinisekisa ukunamathela kwexesha elide kwaye inciphisa umngcipheko wokuwa kweethayile okanye ukuguquka.
C. ukuba bhetyebhetye:
Ibonelela ngokuguquguqukayo ukulungiselela ukunyakaza kwe-substrate, ukunciphisa umngcipheko wokuqhekeka okanye ukuphuka kweetayile.
Ilungele iindawo ezithanda ukungcangcazela okanye ukwandiswa kwe-thermal/contraction.
d. Ugcino lwamanzi:
Igcina ukufuma okwaneleyo ngaphakathi kwe-binder ukukhuthaza ukuhanjiswa okufanelekileyo kwe-cementitious material.
Ukuphucula ukunamathela kunye nokuthintela ukomiswa kwangaphambi kwexesha, ngakumbi kwiimeko ezishushu okanye ezinomoya.
e. Ayinatyhefu kwaye ihambelana nokusingqongileyo:
Ngokuqhelekileyo ayinayo i-volatile organic compounds eyingozi (VOCs) kunye nezinyibilikisi.
Ikhuselekile kubafaki kunye nabahlali ngokufanayo, inceda ukudala indawo enempilo yangaphakathi.
F. Kulula ukufaka kunye nokusebenziseka:
Ukuhambelana okugudileyo kugudiswa kwaye kusebenza ngokulula, ukunciphisa ixesha lokufakela kunye nomgudu.
Igcina ukusebenza okuhambelanayo kwiimeko ezahlukeneyo zemozulu kunye ne-substrates.
G. Antifungal:
Iqulethe izongezo ezimelana nokukhula kwesikhunta, iqinisekisa umgangatho we-tile ococekileyo kunye nobuhle.
H. Uzinzo lokunyibilika komkhenkce:
Iyakwazi ukumelana nemijikelo yokunyibilika komkhenkce ngaphandle kokuchaphazela amandla ebhondi okanye ukuqina.
3. Isicelo:
Umgangatho wokwakhiwa kwe-viscosity ephezulu ye-HPMC yokuncamathelisa ithayile isetyenziswa ngokubanzi kwi:
Ukufakwa kwetayile eludongeni lwangaphakathi nangaphandle: ifanelekile ukulungisa i-ceramic, i-porcelain, iglasi kunye neetayile zamatye endalo kwiindonga kunye neefacade.
Ufakelo lweThayile yoMgangatho: Ukubonelela ngekhonkco elithembekileyo kwiithayile ze-ceramic kwindawo yokuhlala, yorhwebo kunye nezicelo zomgangatho woshishino.
Iindawo ezimanzi: Ifanelekile kumagumbi okuhlambela, amakhitshi, amadama okuqubha kunye nezinye iindawo ezivezwe kukufuma kunye nokufuma.
IiThayile zeFomathi enkulu kunye neeThayile zoMsebenzi oMnzi: Ibonelela ngenkxaso egqwesileyo yeethayile ezinkulu nezinzima ukuthintela ukutyibilika okanye ukuwa.
IiNgqungquthela kunye noLungiso: Ingasetyenziselwa ukufakela ii-tile ezingaphezulu okanye ukulungisa ukufakwa kweethayile ezonakalisiweyo.
4. Imiyalelo yesicelo:
Ukuqinisekisa ukusebenza ngokupheleleyo kunye nokuphila ixesha elide, landela ezi zikhokelo jikelele xa usebenzisa i-high-viscosity yokwakha-ibakala lokuncamathelisa ithayile HPMC:
Ukulungiswa komphezulu: Qinisekisa ukuba i-substrate icocekile, ilungile kwaye ayinathuli, igrisi okanye izingcolisi.
Ukuxuba: Landela imiyalelo yomenzi wokuxuba umlinganiselo, ubungakanani bamanzi onokuthi wongezwe, kunye nexesha lokuxuba ukufezekisa ukuhambelana okufunekayo.
Isicelo: Faka i-adhesive ngokulinganayo kwi-substrate usebenzisa i-trowel yobungakanani obufanelekileyo, uqinisekisa ukugubungela okupheleleyo.
Ukufakwa kwe-tile: Cinezela i-tile ngokuqinileyo kwi-adhesive, uqinisekise ukulungelelaniswa okufanelekileyo kunye nokupakisha okwaneleyo.
I-Grouting: Ngaphambi kokucoca i-tile, vumela i-adhesive ukuba iphilise ngokweengcebiso zomenzi.
Ukunyanga: Khusela iithayile ezisanda kufakwa kumswakama ogqithisileyo, ukuguquguquka kweqondo lobushushu kunye netrafikhi ngexesha lokuqala lokunyanga.
Ukucoca: Hlamba izixhobo kunye nezixhobo ngamanzi ngoko nangoko emva kokusetyenziswa ukukhusela intsalela encamathelayo ekubeni lukhuni.
Umgangatho wokwakhiwa kwe-viscosity ephezulu ye-HPMC yokunamathela kwithayile ibonelela ngesisombululo esithembekileyo sokudibanisa iithayile kwiinkqubo ezahlukeneyo zokwakha. Ngamandla ayo aphezulu okudibanisa, ukuguquguquka kunye nokulula kokusetyenziswa, kwandisa ukusebenza kunye nokuqina kofakelo lwee-tile. Ngokulandela izikhokelo zesicelo esifanelekileyo kunye nokukhetha iimveliso ezikumgangatho ophezulu, iikontraki kunye nabanini bezindlu banokufikelela kwimigangatho ye-tile ehlala ixesha elide kunye neyokubona kwiindawo zombini ngaphakathi nangaphandle.
