I-redispersible latex powder (RDP) yinto ephambili yokongeza izinto zokwakha ezisetyenziswa ngokubanzi kwi-adhesives tile. Ayiphuculi nje kuphela iipropathi ezahlukahlukeneyo zokuncamathelisa i-tile, kodwa iphinda isombulule ezinye zeentsilelo zezinto ezidibeneyo zendabuko.
1. Ukuphucula ukubambelela
Omnye weyona misebenzi iphambili ye-latex powder ehlaziywayo kukuphucula amandla okubopha ama-adhesive tile. I-adhesives esekelwe kwi-samente yendabuko yenza imveliso eqinile emva kokufakwa kwamanzi, inika amandla athile okudibanisa. Nangona kunjalo, ukuqina kwezi mveliso lukhuni kunciphisa ukunamathela. I-powder ye-latex ye-redispersible iphinda ihlakazwe emanzini ukuze yenze iincinci ze-latex, ezizalisa ii-pores kunye nokuqhekeka kwezinto ezisekelwe kwi-samente kwaye zenze ifilimu enamathelayo eqhubekayo. Le filimu ayigcini nje ukwandisa indawo yoqhagamshelwano, kodwa inika i-adhesive iqondo elithile lokuguquguquka, ngaloo ndlela iphucula kakhulu amandla okudibanisa. Olu phuculo lubaluleke kakhulu kufakelo lweethayile zeceramic apho kufuneka amandla ebhondi ephezulu.
2. Ukuphucula ukuguquguquka kunye nokumelana nokuqhekeka
I-latex powder ephinda ikwazi ukunika i-tile adhesives ukuguquguquka okungcono kunye nokumelana nokuqhekeka. Kwii-adhesives, ubukho be-RDP benza ukuba i-adhesive layer ibe ne-elasticity ethile, ukwenzela ukuba ikwazi ukumelana nokuguqulwa okuncinci okubangelwa utshintsho lweqondo lokushisa, i-substrate deformation okanye uxinzelelo lwangaphandle. Lo msebenzi uphuculweyo unciphisa umngcipheko wokuqhekeka okanye ukuchithwa, ngokukodwa kwizicelo zeethayile ezinkulu okanye apho iithayile zibekwe kwiindawo zoxinzelelo oluphezulu.
3. Ukuphucula ukunganyangeki kwamanzi
Ukuchasana kwamanzi kubaluleke kakhulu ekusebenzeni kwexesha elide lokunamathela kwiitile. I-latex powder ephinda iphinde isetyenziswe ithintela ngokufanelekileyo ukungena kwamanzi ngokwenza inethiwekhi yepolymer eshinyeneyo. Oku akugcini nje ukuphucula ukunyanzeliswa kwamanzi kwe-adhesive, kodwa kuphucula amandla ayo okumelana nemijikelo yokuqhaqhazela, ukuvumela i-adhesive ye-tile igcine ukubambelela kakuhle kunye nokuzinza kwesakhiwo kwiindawo ezifumileyo.
4. Ukuphucula ulwakhiwo kunye neeyure zokuvula
I-latex powder ephinda iphinde ikwazi ukuphucula ukusebenza kokwakhiwa kwee-adhesives tile. Izinto ezincamathelayo ezongeziweyo nge-RDP zine-lubricity engcono kunye nokusebenza, okwenza ulwakhiwo lube lula ngakumbi. Ngexesha elifanayo, ikwandisa ixesha elivulekileyo lokubambelela (oko kukuthi, ixesha elisebenzayo lokuba i-adhesive inokubambelela kwi-tile emva kwesicelo). Oku kubonelela abasebenzi bokwakha ixesha elide lokusebenza, kunceda ekuphuculeni ukusebenza kakuhle kunye nomgangatho.
5. Ukuphucula ukumelana nemozulu kunye nokuqina
Ukuchasana kwemozulu kunye nokuqina zizinto ezibalulekileyo ezichaphazela ukusebenza kwexesha elide lokunamathiswa kweetayile. Iinqununu zepolymer kwi-RDP cross-link ngexesha lenkqubo yokunyanga i-adhesive, eyenza inethiwekhi yepolymer ezinzile kakhulu. Le nethiwekhi inokuxhathisa ngokufanelekileyo impembelelo yezinto ezisingqongileyo ezifana nemitha ye-ultraviolet, ukuguga kwe-thermal, ukuguguleka kwe-asidi kunye ne-alkali, ngaloo ndlela kuphuculwe ukuchasana kwemozulu kunye nokuqina kwe-adhesive tile kunye nokwandisa ubomi bayo benkonzo.
6. Nciphisa ukufunxa kwamanzi kwaye uphucule ukumelana nokungunda
I-latex powder ye-latex edibeneyo inokunciphisa izinga lokufunxa kwamanzi kwi-adhesives ye-tile, ngaloo ndlela inciphisa ukungaphumeleli kwe-bonding layer okubangelwa ukwanda kwe-hygroscopic. Ukongeza, i-hydrophobic polymer component ye-RDP inokuthintela ukukhula kwesikhunta kunye nezinye ii-microorganisms, ngaloo ndlela iphucula iipropati ezichasene ne-mildew ye-adhesive tile. Oku kubaluleke ngakumbi kwiindawo ezifumileyo okanye ezinobushushu obuphezulu, njengamagumbi okuhlambela kunye namakhitshi.
7. Ziqhelanise neentlobo ngeentlobo zesubstrates
Redispersible latex powder inika ithayile incamathiso elungileyo ukuguquguquka kwe-multi-substrate. Ingaba iithayile ze-vitrified ezigudileyo, iithayile ze-ceramic ezinokufakwa kwamanzi aphezulu, okanye ezinye ii-substrates ezinjengebhodi yesamente, ibhodi yegypsum, njl. Oku kuvumela uluhlu olubanzi lwezicelo phakathi kweentlobo ezahlukeneyo zeetayile kunye ne-substrates.
8. Ukhuseleko lokusingqongileyo
Izinto zokwakha zanamhlanje zigxininisa ngakumbi ukukhuselwa kwendalo. I-latex powder ye-redispersible idla ngokusetyenziswa kwizinto ezihambelana nokusingqongileyo ezifana ne-polyvinyl alcohol kunye ne-acrylate. Ayinayo i-solvents enobungozi kunye neentsimbi ezinzima kwaye ihlangabezana neemfuno zezinto zokwakha eziluhlaza. Ukongeza, i-RDP ayikhupheli i-volatile organic compounds (VOC) ngexesha lokwakha, ukunciphisa umonakalo kubasebenzi bokwakha kunye nokusingqongileyo.
Ukusetyenziswa kwe-latex powder edibeneyo kwi-ceramic tile adhesives iphucula kakhulu ukusebenza ngokubanzi kwe-adhesive, kubandakanywa ukunamathela, ukuguquguquka, ukuxhathisa kwamanzi, ukwakhiwa, ukuchasana kwemozulu, ukuxhathisa kwe-mildew kunye nokukhuselwa kwendalo. Olu phuculo aluphuculi nje kuphela ukusebenza kakuhle kokwakhiwa kunye nokusebenza kakuhle, kodwa nokwandisa ubomi benkonzo yokubambelela kwi-tile, ebavumela ukuba balungelelanise uluhlu olubanzi lweemeko zesicelo. Ke ngoko, i-RDP ikwindawo ebaluleke kakhulu kuyilo lwangoku lwethayile ye-ceramic encamathelayo, ibonelela ngenkxaso eyomeleleyo yokuphucula umgangatho weeprojekthi zokwakha.
