I-polymer powder ehlakazeka kabusha (RDP)ingenye yezithako ezibalulekile nezibalulekile ezinhlelweni zesimanje zodaka oluxutshwe okomile, ikakhulukazi ezintweni ezinamathelayo zamathayili. Kuyi-polymer ephilayo eguqula i-emulsion ibe yimpushana ngokusebenzisa inqubo yokumisa isifutho. Ine-redispersibility enhle futhi ingakha kabusha i-emulsion ezinzile ngemva kokuxubana namanzi, ngaleyo ndlela inikeze udaka izakhiwo ezinhle kakhulu zokubopha, ukuguquguquka nokusebenza kokwakhiwa.
1. Indlela yokusebenza ye-RDP ekunamathiseleni amathayela
I-adhesive ye-tile ingumkhiqizo wodaka oluxutshwe okomile osetshenziselwa ukuhlanganisa amathayili ebusweni besisekelo, ikakhulukazi owakhiwe usimende, i-aggregate emihle, ukuqina, izithasiselo ze-polymer, njll. Phakathi kwazo, i-RDP, njengesilungisi se-polymer, ingathuthukisa ngokuphawulekayo ukusebenza okuphelele kokunamathela kwe-tile. Indlela yokusebenza kwayo imi kanje:
1.1. Amandla okubopha athuthukisiwe
Ifilimu ye-polymer eyakhiwe yi-RDP ngemuva kokufakwa kwe-hydration ingangena esakhiweni se-microporous sesisekelo ukuze yenze ukulunywa ngomshini, futhi ihambisane nomkhiqizo we-cement hydration ukuze kuthuthukiswe amandla okubopha phakathi kwe-adhesive tile nama-tile kanye nesizinda sesisekelo.
2.1. Thuthukisa ukuguquguquka
Ifilimu ye-polymer inokuguquguquka okuhle futhi ingakwazi ukumunca ngempumelelo ukucindezeleka okubangelwa ukwanda nokufinyela okushisayo noma ukugudluzwa kancane kwesendlalelo sesisekelo ukuvimbela amathayili ukuthi angaqhekeki noma awa.
2.3. Thuthukisa ukusebenza kokwakha
I-RDP inweba isikhathi sokusebenza sokunamathela kuthayela, ithuthukisa ukuthambisa nomuzwa wokwakha, futhi ithuthukisa ukusebenza kahle kokwakhiwa.
2.4. Thuthukisa ukumelana nokuqhekeka nokungakwazi ukungena emanzini
Ifilimu ye-polymer ingagcwalisa izimbotshana ze-capillary odakeni lukasimende, inciphise i-porosity, futhi ithuthukise ukumelana nokuqhekeka nokungakwazi ukungena.
2.5. Thuthukisa ukuqina nokumelana namanzi
I-RDP ithuthukisa ukumelana kwesistimu yodaka endaweni yangaphandle (njengomswakama, izinga lokushisa eliphezulu, iqhwa-ncibilika, njll.) futhi yandisa impilo yesevisi ye-adhesive tile.
2. Izinzuzo zokusebenza kwe-RDP
Ukusetshenziswa kwe-RDP ekwakhiweni kwe-adhesive tile kunezinzuzo ezibalulekile ezilandelayo:
Amandla okubopha okuphezulu: athuthukisa ngokuphawulekayo amandla okubopha okunamathela kuthayela kuthayela (okuhlanganisa amathayela aqinisekisiwe, amathayela aphucuziwe, njll.), futhi ijwayelana nezindawo eziyisisekelo ezihlukahlukene.
Ukuzivumelanisa nezimo ezihlukene: I-RDP inikeza intelelo yamathayili ukumelana namanzi okuhle, ukumelana nokuncibilika kweqhwa, nokumelana nokuguga, futhi ifanele izindawo ezihlukahlukene zokwakha zangaphakathi nangaphandle.
Ukuvumelana nezimo okuqinile: Ifanele izimo ezidingeka kakhulu njengokwakhiwa kongqimba oluncane, amathayela anosayizi omkhulu, namathayili obondeni.
Ihambisana nemvelo futhi iphephile: I-RDP iyimpahla engenabuthi futhi engenaphunga ehlangabezana nezidingo zokuvikela imvelo zezinto zokwakha eziluhlaza.
3. Umthamo onconyiwe kanye nereferensi yefomula
Inani elinconyiwe le-RDP kufanele linqunywe ngokwezinga lokusebenza, isimo sohlelo lokusebenza kanye nesistimu yefomula yokunamathisela ithayela. Ibanga elijwayelekile limi kanje:
I-adhesive ye-tile evamile (uhlobo lwe-C1): Inani elinconyiwe lokwengeza liyi-1.5% ~ 3% yesisindo esiphelele se-glue powder.
I-adhesive yethayela esebenza kahle kakhulu (uhlobo lwe-C2): Inani elinconyiwe lokwengezwa ngu-3%~6%, noma ngaphezulu.
I-adhesive tile enamathelayo (uhlobo lwe-S1/S2): Inani elingeziwe lingaba phezulu ngokufika ku-6%~10% ukuze kuthuthukiswe ukuguquguquka namandla okuthutha.
Ifomula yesithenjwa (isibonelo sokunamathela kwethayela lebanga le-C2):
Ojwayelekile usimende wasePortland: 40%
Isihlabathi se-quartz (0.1-0.3mm): 50%
I-RDP: 4%
I-HPMC: 0.3%
I-Anti-slip agent: 0.1%
I-Defoamer: inani elifanele
I-ejenti yokugcina amanzi/ezinye izithasiselo: ukulungisa kahle ngokwezidingo
4. Izinhlobo zamathayili asebenzayo nezimo ze-substrate
I-adhesive ye-tile elungiswe nge-RDP ifanele izinhlobo ezahlukene zamathayili nama-substrates, okuhlanganisa kodwa akukhawulelwe kulokhu:
Izinhlobo zamathayili: amathayela acwebezelisiwe, amathayela aphucuziwe, amathayela acwebezelwe, ama-mosaic, imabula, amatshe okwenziwa, njll.
Izinhlobo ze-substrate: isisekelo sodaka lukasimende, ibhodi likasimende, ibhodi legypsum, isisekelo sethayela elidala, ibhodi likakhonkolo, njll.
I-adhesive ye-tile eshintshwe nge-RDP ifaneleka ngokukhethekile ukugandaywa kwamathayili aphansi amunca amanzi kanye namathayili anosayizi omkhulu, okungaxazulula ngempumelelo inkinga yamandla anganele okubopha odaka lukasimende lwendabuko.
5. Izinyathelo zokuphepha
Ngesikhathi sokukhiqiza kanye nenqubo yokufaka isicelo, amaphuzu alandelayo kufanele aqashelwe:
Khetha uhlobo olufanele lwe-RDP (njenge-ethylene-vinyl acetate copolymer EVA, i-acrylic polymer, njll.) ukuze uhlangabezane nezidingo zokusebenza ezahlukene.
Gcina womile ngesikhathi sokugcina ukuze ugweme umswakama kanye ne-agglomeration.
Ungagcini ngezinto ezine-alkaline kakhulu isikhathi eside ukuze uvimbele ukuthi ukusebenza kungaphazamiseki.
Xuba ngokulinganayo ukugwema ukusatshalaliswa okungalingani kwezimpushana okuholela ekusebenzeni okungazinzile.
Njengomsebenzi owumgogodla wokunamathela kuthayela, izimpushana ze-polymer ezihlakazeka kabusha zithuthukisa kakhulu amandla okubopha, ukuguquguquka nokuqina kwezinamathelisi zamathayili, zihlangabezana nezidingo zezakhiwo zesimanje zezinto zokugandaya zamathayili ezisebenza kahle kakhulu. Esikhathini esizayo, ngokuthuthukiswa kokwakhiwa kwezimboni, iukusetshenziswa kwe-RDP ezintweni ezinamathelayo zamathayela kanye nemikhiqizo yodaka exutshwe owomileizokwanda kakhulu, futhi ukusebenza kwayo kanye nezinzuzo zemvelo kuzoqhubeka nokukhuthaza imboni yezinto zokwakha ibe sezingeni eliphezulu.
