Usebenzisa i-HPMC ukwakha udaka lwe-EIFS

Ukufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIF) zodaka zidlala indima ebalulekile ekunikezelweni kwezinyembezi, ukuvimba isimo sezulu kanye nama-aesthetics ezakhiweni. I-Hydroxypropyl Methylcellulose (HPMC) isengezo esisetshenziswa kakhulu ku-EIFS sokwenziwa ngenxa yokusebenza okuhlukahlukene, ukugcinwa kwamanzi kanye nekhono lokwenza ngcono ukusebenza.

1. Isingeniso ku-Eifs Gunator:

I-EIFS ngodaka iyinto eyinhlanganisela esetshenziselwa ukufakwa nokuqedwa kwezinhlelo zodonga ezingaphandle.

Imvamisa iqukethe i-Conment Binder, ama-aggregates, imicu, izengezo namanzi.

Udaka lwe-EIFS lungasetshenziswa njenge-primer yokujoyina amaphaneli wokuhlanganisa kanye ne-topcoat ukuthuthukisa ama-aesthetics kanye nokufaka isimo sezulu.

I-HPMC iyi-cellulose ether ethathwe ku-polymer cellulose yemvelo.

Kusetshenziswa kabanzi ezintweni zokwakha zokugcina kwayo, ukuqina nokusebenza okuthuthukisa ukwakhiwa kabusha.

Ku-EIFS donsa, i-HPMC isebenza njengokushintshwa kwe-Rheology, ukuthuthukisa ukunamathela, ukubumbana kanye nokumelana kwe-sag.

3. Izithako zefomula:

a. I-Conmende-based Binder:

IPortland Cement: Inikeza amandla nokunamathelisa.

Usimende ohlanganisiwe (isib. I-Portland Limestone Cement): Yandisa ukuqina futhi yehlisa i-carbon footprint.

b. Ukuhlanganiswa:

Isihlabathi: ivolumu kanye nokuthungwa kokuhlangana okuhle.

Izihlanganisi ezingasindi (isib. I-Perlite enwetshiwe): Thuthukisa izakhiwo zokufaka okushisayo.

C. I-fiber:

I-ALkali-Ukumelana ne-fiberglass: Ithuthukisa amandla ashubile nokumelana nokuqhekeka.

d. Izithasiselo:

I-HPMC: Ukugcinwa kwamanzi, ukusebenziseka kanye nokumelana kwe-sag.

Umenzeli ongenisa umoya: Thuthukisa ukumelana kwe-freeze-thaw.

I-Retardar: Izilawuli zokusetha isikhathi ezindaweni ezishisayo.

I-Polymer Modifers: Thuthukisa ukuguquguquka nokuqina.

e. Amanzi: abalulekile kuma-hydration nokusebenza.

4. Izici ze-HPMC ku-EIFS udaka:

a. Ukugcinwa kwamanzi: I-HPMC imunca futhi igcina amanzi, iqinisekisa i-hydration yesikhathi eside kanye nokwenza ngcono ukusebenziseka.

b. Ukusetshenziswa: I-HPMC inika ubushelelezi bodaka nokuvumelana, okwenza kube lula ukwakha.

C. Anti-SAG: I-HPMC isiza udaka ngodaka olusuka ekuhlaseleni noma ekunciphiseni ezindaweni ezibheke mpo, uqinisekise ubukhulu be-Uniform.

d. I-Adhesion: I-HPMC ithuthukisa ukunamathela phakathi kodaka kanye ne-substrate, ukukhuthaza ukunamathela kwesikhathi eside nokuqina.

e. Ukumelana nokuqhekeka: I-HPMC ithuthukisa ukuguquguquka namandla abopha amandla odaka futhi inciphisa ubungozi bokuqhekeka.

5. Inqubo yokuxuba:

a. Indlela Yamanje Emanzi:

I-Pre-Wet the HPMC esitsheni esihlanzekile esinamaphesenti angama-70-80% amanzi ahlanganisiwe.

Hlanganisa izithako ezomile (usimende, ohlanganisiwe, imicu) ku-mixer.

Kancane kancane engeza isixazululo se-HPMC esisePPMC ngenkathi uvusa kuze kufinyelele ekuguqukeni okufunayo.

Lungisa okuqukethwe kwamanzi njengoba kudingeka ukuze uzuze ukusebenziseka okufiselekayo.

b. Indlela yokuxuba eyomile:

I-Dry Mix HPMC enezithako ezomile (usimende, ama-aggregates, imicu) ku-mixer.

Kancane kancane engeza amanzi ngenkathi uvusa kuze kube ukuvumelana okufisayo kufinyelelwe.

Hlanganisa kahle ukuze uqinisekise ukusatshalaliswa kwe-HPMC nezinye izithako.

C. Ukuhlolwa kokuvumelana: Ukuhlolwa kokuhambisana ne-HPMC nezinye izengezo zokuqinisekisa ukusebenzisana okuhle nokusebenza.

6. Ubuchwepheshe besicelo:

a. Ukulungiselela kwe-substrate: qiniseka ukuthi i-substrate ihlanzekile, yomile futhi mahhala.

b. Isicelo se-Primer:

Faka isicelo sokuqala kodaka lwe-EIFS ku-substrate usebenzisa i-trowel noma imishini yokufafaza.

Qiniseka ukuthi ubukhulu bukhona futhi ukumbozwa kuhle, ikakhulukazi emaphethelweni nasemakhoneni.

Shumeka ibhodi lokufaka ku-oda olwenzile futhi livumele isikhathi esanele sokwelapha.

C. I-Topcoat application:

Faka isicelo se-topcoat ye-EIFS yodaka ngaphezulu kwe-primer evuthayo usebenzisa i-trowel noma imishini yokufafaza.

Ukuthungwa noma ukuqeda indawo njengoba kufiswa, ukunakekela ukufeza ukufana kanye nama-aesthetics.

Phulukisa i-topcoat ngokuya ngezincomo zomkhiqizi ukuze uyivikele ezimweni zezulu ezinzima.

7. Ukulawulwa kwekhwalithi nokuhlola:

a. Ukungaguquguquki: qapha ukungaguquguquki kodaka kuyo yonke inqubo yokuxuba nenqubo yokufaka isicelo ukuze uqinisekise ukufana.

b. Adhesion: Kwenziwa ukuhlolwa kokunamathela ukuze kuhlolwe amandla e-bond phakathi kodaka kanye ne-substrate.

C. Ukusetshenziswa: Hlaziya Ukusetshenziswa Ngokuhlolwa Kokushelela Nokubukwa ngesikhathi sokwakha.

d. Ukuqina: phatha ukuhlolwa kokuqina, kufaka phakathi imijikelezo ye-freeze -tha-thaw kanye nokuvimbela amanzi, ukuhlola ukusebenza kwesikhathi eside.

Usebenzisa i-HPMC yokwenza odoti abakwa-EIFS unikeza izinzuzo eziningi ngokuya ngokusebenza, ukunamathela, ukumelana kwe-SAG nokuqina. Ngokuqonda izakhiwo ze-HPMC futhi kulandela izindlela ezifanele zokuxuba kanye nezinsiza, osonkontileka bangathola ukufakwa okuphezulu kwe-EIFS okuhlangabezana namazinga okusebenza futhi kwandise ama-aesthetics wokwakha kanye nokuphila isikhathi eside.
