Ukwandisa Ukumelana Nokuqhekeka Kuma-Plasters: Indima Ebalulekile Ye-HEC Kuma-Gypsum Nakuma-Cement Mixes

Ama-plaster—okubili asekelwe ku-gypsum kanye nosimende—avame ukuqhekeka ngesikhathi sokomiswa ngenxa yokulahlekelwa umswakama okusheshayo kanye nokucindezeleka okungalingani kwe-substrate. Ukushwabana, ukushintshashintsha kokushisa, kanye nokungahambisani okubangelwa abantu (njengokusetshenziswa okungacacile) kwenza kube nzima ukuqhekeka. Ukubhekana nalezi zingcindezi zesigaba sokuqala kubalulekile ekuqedeni okuhlala isikhathi eside nokuhle.

1. Ukugcinwa Kwamanzi Okuthuthukisiwe

I-HEC yakha inethiwekhi ebamba amanzi, yehlisa ijubane lokuhwamuka kwamanzi futhi ivumela umswakama ogcwele. Lokhu kunciphisa ukushwabana kwasekuqaleni kanye nokuqhekeka okuncane, ikakhulukazi ezimweni ezishisayo noma ezomile.

2. Ukulawulwa kwe-Viscosity kwesicelo esifanayo

Ngokufaka i-viscosity enembile, i-HEC iqinisekisa ukuthi izingxube ze-plaster zihlala zifana, igwema ukuhlukaniswa nokuwa ngesikhathi sokusetshenziswa—izici ezibalulekile ekwakhekeni kwemifantu. .

3. Ukuqina Okuthuthukisiwe Nokuguquguquka

I-HEC inikeza inethiwekhi ye-polymeric emunca ukucindezeleka futhi inciphise ama-plaster aqinile, alulame kalula. Ithuthukisa ukuqina, okuvumela ukunyakaza okuncane kwe-substrate ngaphandle kokubangela ukuqhekeka.

4. Izakhiwo Ezingcono Zokunamathela Nokwakha Amafilimu

Ukuntuleka kokunamathela ezindaweni zokuhlangana kuholela ekuqhekekeni. I-HEC iqinisa ukubopha phakathi kweplasta kanye ne-substrate (noma phakathi kwezingqimba), futhi yakha izingqimba zefilimu eziguquguqukayo ukuze kuncishiswe ukuhlukana .

5. Isakhiwo Sembobo Ecwengisisiwe

I-HEC ikhuthaza ukusatshalaliswa kwe-pore okuqinile, okuthuthukisa ubuningi kanye nokunciphisa ukuguquguquka kokuncipha—okufaka isandla ekuzinzeni kwesikhathi eside kanye nokumelana nomswakama .

Izicelo Eziwusizo kanye Nezibonelo Zecala

1. Amaplasta e-Gypsum

Ezinhlelweni ze-gypsum, i-HEC ithuthukisa ukugcinwa kwamanzi futhi yakha ifilimu evikelayo ngesikhathi sokusetha—ukunciphisa imifantu yokuncibilika nokuthuthukisa amandla obuso nokunamathela.

2. Ama-Plaster Asekelwe Kusimende

Ukwengeza i-HEC kusimende kukhulisa ukujiya, ukufuthwa kahle, kanye nokuqina kokusetshenziswa. Kusiza ukugcina umswakama futhi kuvimbele ukugoba noma ukuqhekeka okuqondile

3. Ama-plaster alula futhi e-EIFS

Amaplasta alula aphathwe nge-HEC abonisa ukushelela okuthuthukisiwe, ukunamathela, kanye nokuqina—afanelekela ukuqedwa kodonga lwesimanje kanye nezinhlelo zokuvikela zangaphandle

Isiphetho

I-Hydroxyethyl cellulose iyisengezo esinomthelela omkhulu, esingabizi kakhulu esiqinisa ukumelana nokuqhekeka ezinhlelweni zeplasta. Ngokwenza ngcono ukugcinwa kwamanzi, ukunamathela, ukunamathela, kanye nokuguquguquka kwesakhiwo, i-HEC iletha ukuqeda okubushelelezi, izibopho eziqinile, kanye nemiphumela ehlala isikhathi eside—izuzisa ochwepheshe bezakhiwo kanye nabathengi.
