Embonini yezokwakha, ukunamathela okususelwa ku-tile-based tile kudlala indima ebalulekile ekuqinisekiseni ukuqina nokuphila isikhathi eside kwe-tile surface. Lezi zinamathelisi zibalulekile kumathayili ahlanganisa ngokuqinile ukuze afake ama-substrates anjengokhonkolo, ngodaka, noma indawo ekhona yethayela. Phakathi kwezinto ezahlukahlukene zokunamathela okususelwa ku-cutem-based tile, i-hpmpypropylm methylcellulose (HPMC) ivelele njengesithako esiyisihluthulelo ngenxa yezakhiwo zayo eziningi kanye nomnikelo ekusebenzeni kohlelo lokunamathela.
1. Qonda i-HPMC:
I-Hydroxypropylmethylceltelcelcellellellulose (HPMC) yi-Enion Cellulose Ether ethathwe kuma-polymers wemvelo, ngokuyinhloko iselula. Isetshenziswa kakhulu ezintweni zokwakha njengodoti we-Rheology, i-ejenti yokugcina amanzi kanye nokunamathela. I-HPMC ihlelwe ngochungechunge lokuguqulwa kwamakhemikhali ku-cellulose, okuholele ku-polymer esolulekayo yamanzi ngezakhiwo ezihlukile ezilungele izinhlelo ezahlukahlukene zokwakha, ezenza imithi kanye nezimboni zokudla.
I-2.I Iqhaza le-HPMC ku-Cement-based Tile Adhesive:
Ukugcinwa kwamanzi: I-HPMC inokugcinwa kwamanzi okuhle kakhulu, okuvumela ukunamathela ukuze kugcinwe ukungaguquguquki okufanele nokusebenza ngokuhamba kwesikhathi. Le mpahla ibalulekile ukuvikela ukoma ngaphambi kwesikhathi kokunamathela, qiniseka ukuthi i-hydration eyanele yezakhi zosethusi, futhi ithuthukise amandla ebhondi phakathi kwethayela kanye ne-substrate.
Ukuguqulwa kwe-Rheology: I-HPMC isetshenziswa njenge-Rheology modifier, okuthinta indlela yokugeleza kanye nokubonakaliswa kosimende-based tile adhesives. Ngokulawula i-viscosity, i-HPMC ingafaka kalula ukunamathela, ukukhuthaza ngisho nokumboza ngisho nokunciphisa ubungozi bamathayili ashelelayo ngesikhathi sokufakwa. Ngokwengeziwe, kusiza ukushelela okubushelelezi futhi kuthuthukise ukusakazeka okunamathela, ngaleyo ndlela kuthuthukise ukusebenziseka kanye nokunciphisa amandla abasebenzi.
Ukunamathela okuthuthukisiwe: I-HPMC isebenza njengokunamathela, ukuthuthukisa ukunqwabelana phakathi kokunamathela kanye ne-tile ephezulu kanye ne-substrate. Ukwakheka kwalo kwamangqamuzana kwakha ifilimu elinamathelayo lapho i-hydrate, ibopha ngempumelelo okunamathela ezintweni ezahlukahlukene, kufaka phakathi ubumba lwe-ceramics, i-porcelain, itshe lemvelo kanye nezindawo eziphansi zemvelo. Le mpahla ibalulekile ekufezeni ukunamathela okuqinile, okuhlala isikhathi eside, ukuvimbela ukuqunjelwa kwe-tile kanye nokuqinisekisa ubuqotho besakhiwo sendawo yethayi.
Ukumelana nokuqhekeka: I-HPMC inika usimende-based tile adhesive anamathela futhi ithuthukise ukumelana nokuqhekeka. Ngoba amathayili angaphansi kokucindezelwa kwemishini kanye nenhlangano yesakhiwo, ukunamathela kumele kube ukunwebeka ngokwanele ukwamukela lezi zinto ngaphandle kokuqhekeka noma ukunxusa. I-HPMC ithuthukisa ukuguquguquka kwe-matrix enamathela, ukunciphisa amandla okufakelwa futhi kuqinisekiswe ukuqina kokufakwa kwe-tile, ikakhulukazi ezindaweni eziphakeme kakhulu noma ezindaweni ezithambekele ekushintsheni kwezinga lokushisa.
Ukuqina kanye nokumelana kwesimo sezulu: Ukungezelelwa kwe-HPMC kuthuthukisa ukuqina nokumelana nesimo sezulu sokunamathela okususelwa kusazi. Inikeza ukumelana okwengeziwe kokungena kwamanzi, i-freeze-thaw imijikelezo nokuvezwa kwamakhemikhali, ukuvikela ukonakala kanye nokugcina ubuqotho bendawo yethayi ezisetshenzisweni ezingaphakathi nangaphandle. Ngokwengeziwe, i-HPMC isiza ukunciphisa imiphumela yesimo sezulu, iqinisekise ukuthi ukufakwa kwe-tile kuhlala kukuhle ngokuhamba kwesikhathi.
I-3. Izinzuzo ze-HPMC ku-Cement-based Tile Adhesives:
Ukusebenza okuthuthukile: I-HPMC ithuthukisa ukusebenza kohlelo lokusebenza lwe-TEMEMED ADHINTS, okwenza kube lula ukuxuba, ukufaka futhi bushelelezi. Osonkontileka bangafinyelela imiphumela engaguquki ngomzamo omncane, ukonga isikhathi nemali ngesikhathi senqubo yokufaka.
Amandla eBond athuthukisiwe: Ukuba khona kwe-HPMC kukhuthaza isibopho esiqinile phakathi kwethayela, okunamathelayo kanye ne-substrate, okuholela emandleni amakhulu amakhulu kanye nengozi encishisiwe yokutholwa kwethayela noma ukwehluleka. Lokhu kuqinisekisa ukusebenza kwesikhathi eside nokuqina kwendawo yethayela ezindaweni ezahlukahlukene.
Ukuguquguquka: Adhesives asuselwa ku-HPMC anezinto eziguquguqukayo futhi alungele ukusetshenziswa ezinhlotsheni ezahlukahlukene ze-tile, osayizi kanye nezindawo zokunyumba. Noma ngabe ukufaka i-Ceramic, i-porcelain, itshe lemvelo noma ithayela lemvelo, osonkontileka bangathembela kuma-HPMC anamathela ekuletheni imiphumela engaguquki kusuka kuphrojekthi kuya kwiphrojekthi.
Ukuvumelana: I-HPMC iyahambelana nezinye izengezo kanye nama-admixtures asetshenziswa kakhulu kuma-tile anamathela, njenge-latex modifiers, ama-polymers kanye namakhemikhali athuthukisa ukusebenza. Lokhu kuhambisana kuvumela ukwakheka okwenziwe ngokwezifiso ukufeza izidingo ezithile zokusebenza nezidingo zephrojekthi.
Ukusimama: I-HPMC ithathwe emithonjeni evuselelekayo yeselula, okwenza kube yinkhemweni enobungani yemvelo yezinto zokwakha. I-biodegradeabilibility kanye nomthelela ophansi wezemvelo ufaka isandla emikhakheni yokwakha esimeme nezinhlelo zokwakha eziluhlaza.
4. Ukusetshenziswa kwe-HPMC ku-Cement-based Tile Adhesive:
I-HPMC isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zokunamathela okususelwa kumasimende afaka:
Udaka lwefomu elijwayelekile elijwayelekile: I-HPMC isetshenziswa kakhulu ngodaka lwefomu elijwayelekile elincane lokubopha ubumbano namathayili we-ceramic ukuze ufake amapulangwe anjengokhonkolo, ama-sterts kanye namabhodi angenisa acebile. Ukugcinwa kwalo kwamanzi nokuqothula izithasiselo kuqinisekisa ukufakwa okuthembekile kokufakwa kwe-Indoor nokwangaphandle kweTile.
Ifomethi enkulu i-tile anamathela: ekufakweni okubandakanya amathayili amakhulu wefomethi noma ama-adhesives anesisindo esinamandla, ama-adhesives asuselwa ku-HPMC ahlinzeka ngokuthuthuka kwebhondi nokuqhekeka, avumelane nezimpawu ze-tiension kanye ne-timensional of the tile.
Adhesives Tile Tile: Izicelo ezidinga ukuguquguquka nokuqina, njengokufakwa kwezindawo ezisetshenziselwa ukunyakaza okuthambekele ekunyakazelweni noma ekunwebekeni, i-HPMC ingakha ukunamathela okuguqukayo okungamelana nezimo zesakhiwo. ukuqina noma ukuqina.
I-Hydroxypropylm methylcellulose (HPMC) idlala indima ebalulekile ekwakhekeni nasekusebenzeni kokunamathela okususelwa kusazi, okuhlinzeka ngezinto ezahlukahlukene nezinzuzo ezidingekayo ekufakweni kwethayela eliphumelelayo. Ukusuka ekunikezeni amandla kanye namandla e-bond ekwenzeni ngcono ukusebenziseka nokuqina, i-HPMC isiza ukuthuthukisa ikhwalithi, ukuthembeka nokuphila isikhathi eside kwe-ceramic tile surfaces kumaphrojekthi wokwakha ahlukahlukene. Njengoba imboni yezokwakha iqhubeka nokubeka phambili ukusebenza kahle, ukuqina kanye nokusebenza, ukubaluleka kwe-HPMC ku-Cement-based tile adhesives kuhlala kuhlanganiswa, ukushayela okusha kanye nentuthuko eThithele Ukufakwa Kwezobuchwepheshe.
