Kutheni i-HPMC isisithako esibalulekileyo kwizinto zokuncamathelisa iithayile ezisekwe kwisamente?

Ii-adhesives ze-tile ezisekelwe kwi-cement zisetyenziswa ngokubanzi kumsebenzi woyilo kunye noyilo lwangaphakathi. Zisetyenziselwa ukukhusela iithayile kwiindonga, imigangatho, kunye neminye imiphezulu. Ezi zincamathelisi ziqulethe isithako esibalulekileyo esenza ukuba zisebenze ngakumbi: i-hydroxypropyl methylcellulose (HPMC).

I-HPMC yipolymer yeselulosi elungisiweyo enezicelo ezininzi zemizi-mveliso. Kwii-adhesives ze-tile, isetyenziswe njenge-thickener, i-agent egcina amanzi kunye ne-adhesive. Ngumgubo omhlophe okanye omhlophe, ongenatyhefu, awunavumba kwaye awunancasa.

Xa ifakwe kwi-adhesives ye-cement-based adhesives, ukusebenza kwayo kunokuphuculwa ngeendlela ezininzi. Nazi ezinye izizathu zokuba kutheni i-HPMC isisithako esibalulekileyo kwizinto zokuncamathelisa iithayile zesamente:

1) Ibonelela ngokuphucuka kokuqhubela phambili

I-HPMC iphucula ukusebenza ngokwenza izinto zokuncamathelisa iithayile zesamente zibe lula ukuzisebenzisa kwaye zisasazeke. I-HPMC yandisa i-viscosity ye-adhesive, iyenza idibanise ngakumbi kwaye kulula ukusebenza nayo. Kwakhona kunciphisa ukugoba, nto leyo xa i-adhesive ibaleka okanye ithontsiza ukusuka phezulu.

2) Ukuphucula ukugcinwa kwamanzi

I-adhesives ye-cementitious tile adhesives ngokukhawuleza ilahlekelwa ngumswakama kwi-substrate esetyenziswa kuyo. I-HPMC inceda ekwandiseni ukugcinwa kwamanzi okuncamathelayo, okubaluleke kakhulu ekunyangelweni kokuncamathelisa. Olu phawu luqinisekisa ukuba i-adhesive inobomi obude kwaye inokumelana nomswakama, ukushisa kunye nezinye izinto zokusingqongileyo. Oku kubaluleke ngakumbi xa i-tile ifakwe kwiindawo ezimanzi ezifana nezindlu zangasese kunye namakhitshi.

I-3) Unamathelo angcono

I-HPMC yinto yokuncamathelisa esebenzayo ephucula ukusebenza kwekhonkco lokuncamathelisa kwethayile esekwe kwisamente. Xa ifakwe kwi-adhesive, inceda ukubopha i-samente kunye nezinye iinqununu ze-adhesive kunye, okwenza kube lula ukubamba i-tile kunye nezinye izinto kwi-substrate.

4) Nciphisa iintanda

Ukuqhekeka yenye yeengxaki eziqhelekileyo kunye ne-samente-based adhesives tile adhesives. I-HPMC inokunceda ukunciphisa ukuqhekeka ngokwandisa ukuguquguquka kwe-adhesive kunye nokunciphisa ukushwabana. Oku kubaluleke ngakumbi xa iithayile zibekwe kwisubstrates ezisuseka lula njengemithi okanye umphezulu wentsimbi.

5) Ukuphucula ukuqina

I-HPMC inokuphucula ukuqina kwezinto zokuncamathelisa iithayile ezisekwe kwisamente. Ikhusela i-adhesive ekuqhekekeni ngenxa yokuvezwa kumswakama kunye nezinye izinto zokusingqongileyo. Kwakhona kunciphisa inani le-efflorescence eyakha phezu komhlaba we-tile.

6) Yandisa isantya esimiselweyo

I-HPMC inceda ukukhawulezisa ukusetwa kwezincamathelisi zeethayile ezisekelwe kwisamente. Oku kubalulekile xa ixesha liyimfuneko kwaye i-adhesive idinga ukuseta ngokukhawuleza ukugcina i-tile ngokukhuselekileyo.

7) Nciphisa ithuba lokuqhekeka kwe-grout

I-HPMC inceda ukunciphisa ukubakho kokuqhekeka kwegrout. Ukuqhekeka kwe-Grout kwenzeka xa ukunyakaza kwe-substrate kuphula ibhondi phakathi kwe-tile kunye ne-adhesive. I-HPMC inokwenza i-adhesive i-elastic engaphezulu, enceda ukufunxa intshukumo ye-substrate kwaye ithintele iintanda ze-grout ukuba zenze.

Isishwankathelo, i-HPMC yinxalenye ebalulekileyo ye-samente-based adhesives tile. Iimpawu zayo ezininzi zenza ukuba ibe yinxalenye ebalulekileyo yayo nayiphi na i-adhesive esetyenziselwa ukubeka iileyile. Idlala indima ebalulekileyo kwisigxina, ukusebenza kunye nokubambelela kwi-adhesive. Xa ifakwe kwi-adhesives ye-cement-based adhesives, iqinisekisa ukusebenza kakuhle, ixesha elide kunye nokwaneliseka kwabathengi.
