Ifomula yokunamathela kanye nesicelo se-HPMC-tile

Adhesives tile adlala indima ebalulekile embonini yezokwakha, eqinisekisa ukubopha okuvikelekile kwamathayili ezindaweni ezahlukahlukene. I-Hydroxypropyl Methylcellulose (HPMC) iyisithako esiyisihluthulelo ezinamathela ezinamathele zanamuhla, ukuhlinzeka ngezakhiwo ezinamathela ezithuthukisiwe nokusebenza.

I-1.Ukuqonda i-Hydroxypypropylllylyll (HPMC):

I-HPMC i-cellulose derivative esetshenziswa kakhulu ezintweni zokwakha zokunamathela kwayo, ukuqina, kanye nokugcinwa kwamanzi.

Kuthathwe kusuka ku-cellulose yemvelo futhi kusetshenzwe ibe yimpuphu enhle.

I-HPMC ithuthukisa amandla eBonding of Tile Adhesives ngenkathi ithuthukisa ukusebenza kwayo kanye nezimpawu zokugcina amanzi.

I-2.Formation ye-HPMC-based tile adhesive:

a. Izithako eziyisisekelo:

IPortland Cement: Inikeza i-ejenti yokubopha okuyisisekelo.

Isihlabathi esihle noma i-filler: ithuthukisa ukusebenza futhi inciphise i-shrinkage.

Amanzi: Kuyadingeka ukuze i-hydration nokusebenza.

I-Hydroxypropyl Methylcellulose (HPMC): Izenzo njenge-ejenti yokuqina nokubopha.

Izengezo: Kunganikeka ama-polymer modifiers, ama-dispersants, kanye nama-anti-sag agents ngezithuthukisi ezithile zomsebenzi.

b. Ukuhlukaniswa:

Ingxenye yesithako ngasinye iyahlukahluka ngokuya ngezinto ezifana nohlobo lwe-tile, ama-substrate, kanye nezimo zemvelo.

Ukwakhiwa okujwayelekile kungahle kube nosimende ongu-20-30%, isihlabathi esingu-50-60%, 0.5-2% hpmc, kanye nokuqukethwe okufanele kwamanzi ukufeza ukuvumelana okudingayo.

c. Inqubo yokuxuba:

Hlanganisa uhlanganise usimende, isihlabathi, ne-hpmc ngokuphelele ukuqinisekisa ukusatshalaliswa komfaniswano.

Kancane kancane engeza amanzi ngenkathi uxuba kuze kube yilapho ukuguquguquka okufisayo kutholakala.

Hlanganisa kuze kube yilapho unamathisela obushelelezi, mahhala-free etholakala, uqinisekisa i-hydrate efanele ye-Cement kanye nokuhlakazwa kwe-HPMC.

I-3.PAPPLICUCTION KWE-HPMC-based tile adhesive:

a. Ukulungiselela okungaphezulu:

Qinisekisa ukuthi i-substrate ihlanzekile, inomsindo ohlelekile, futhi ingenawo uthuli, amafutha, kanye nokungcola.

Izindawo ezinolaka noma ezingalingani zingadinga ukulinganisa noma ukugqama ngaphambi kokufaka isicelo.

b. Amasu okusebenzisa:

Isicelo seTrowel: Indlela evame kakhulu kubandakanya ukusebenzisa i-trowel eboshwe phansi ukusakaza okunamatheli ku-substrate.

I-Back-Butting: Isebenzisa ungqimba omncane wokunamathela emuva kwangemuva kwamathayili ngaphambi kokuwabeka embhedeni wokunamathela kungathuthukisa amabhondi, ikakhulukazi amathayili amakhulu noma asindayo.

I-Spot Bonding: Ilungele amathayili angasindi noma izinhlelo zokuhlobisa, kufaka phakathi izicelo zokuhlobisa, kufaka phakathi ukunamathela kuma-patches amancane kunokuba akwenze kuwo wonke ama-substrate wonke.

c. Ukufakwa kwe-Tile:

Cindezela amathayili ngokuqinile embhedeni wokunamathela, uqinisekise ukuthintana okugcwele kanye nokuthola umfaniswano.

Sebenzisa ama-spacers ukuze ulondoloze ukuhlangana okungaguquki kwe-grout.

Lungisa ukuqondanisa kwe-tile ngokushesha ngaphambi kwamasethi wokunamathela.

d. Ukwelapha nokugoqa:

Vumela ukunamathela ukwelapha ngokuya ngemiyalo yomenzi ngaphambi kokudonswa.

I-Grout the tile usebenzisa impahla efanelekile ye-grout, ugcwalisa amalunga ngokuphelele futhi abusheleleke ebusweni.

4.Amagadi anokunamathela kwe-HPMC-based Tile:

Amandla oBonding athuthukisiwe: I-HPMC ithuthukisa ukunamathela kuzo zombili ama-tile kanye nama-substrates, kunciphisa ubungozi bokuqubuka kwethayela.

Ukusebenza okuthuthukisiwe: Ukuba khona kwe-HPMC kuthuthukisa ukusebenziseka kanye nesikhathi esivulekile sokunamathela, okuvumela uhlelo lokusebenza olulula nokulungiswa kwamathayili.

Ukugcinwa kwamanzi: I-HPMC isiza ukugcina umswakama ngaphakathi kokunamathela, ukukhuthaza i-hydration efanelekile yokulinganisa nokuvimbela ukoma ngaphambi kwesikhathi.

I-HPMC-based tile adhesive inikezela ngesisombululo esithembekile sezicelo ezahlukahlukene ze-tiling, enikeza ukunamathela okuqinile, ukukhiqizwa okuthuthukile, nokuqina okuthuthukile. Ngokuqonda amasu okuhleleka kanye namasu okusebenzisa achazwe kulo mhlahlandlela, ochwepheshe bezokwakha bangasebenzisa ngempumelelo ukunamathela kwe-HPMC ukufezekisa ukufakwa kwe-tile ephezulu.
