Ukusetshenziswa kwe-Hydroxyethyl Methyl Cellulose ku-Spray Mortar

I-Hydroxyethyl Methyl Cellulose (HEMC)iyi-cellulose ether engeyona i-ionic encibilikayo emanzini enokujiya okuhle kakhulu, ukugcinwa kwamanzi, ukuthambisa kanye nezakhiwo zokwakha ifilimu. Isetshenziswa kabanzi ezintweni zokwakha, ezimbozweni, kumakhemikhali ansuku zonke nakwamanye amasimu. Eminyakeni yamuva nje, ngentuthuko yezimboni zokwakha kanye nokwakhiwa kwemishini yokwakha, i-spray mortar iye yathatha indawo kancane kancane yokwakha kwendabuko yokuplasta ngesandla futhi yaba uhlobo olusha lwendlela yokwakha esebenza kahle futhi enobungani nemvelo. Ukusetshenziswa kwe-HEMC ku-spray mortar kuthuthukise kakhulu ukusebenza kokwakhiwa kanye nekhwalithi yomkhiqizo oqediwe we-mortar, futhi ingenye yezithasiselo ezibalulekile kule nsimu.

1. Ukubuka Konke Nge-Spray Mortar

I-spray mortar iyi-mortar exutshwe kusengaphambili eyakhiwe ngemishini yokufafaza, okuhlanganisa i-plastering mortar, i-thermal insulation mortar, i-self-leveling mortar nezinye izinhlobo. Uma kuqhathaniswa nokwakhiwa kwendabuko ngesandla, i-spray mortar inezinzuzo zesivinini sokwakha esisheshayo, amandla aphansi abasebenzi, ikhwalithi yokwakha ezinzile, futhi ifanele imisebenzi yendawo enkulu. Kodwa-ke, ngenxa yenqubo yokufafaza esheshayo neqhubekayo, izidingo eziphakeme zibekwe ekusebenzeni kahle, ukunamathela kanye nokugcinwa kwamanzi kwe-mortar.

2. Izici zokusebenza ze-HEMC

I-hydroxyethyl methylcellulose inamaqembu asebenzayo e-hydroxyethyl kanye ne-methoxy, okuyinika lezi zakhiwo ezinhle kakhulu:

Ukuncibilika kwamanzi okuhle kakhulu kanye nokuqina: I-HEMC incibilika ngokushesha emanzini abandayo ukuze yakhe isixazululo esibonakalayo noma esikhanyayo esiqinile, esifanele izinhlelo ezahlukene zodaka oluxubile olomile.

Ukugcinwa kwamanzi kahle kakhulu: Isakhiwo sayo sama-molecule singavimba umswakama ngempumelelo, sivimbele umswakama ukuthi ungahwamuki ngokushesha okukhulu, futhi sithuthukise ukuthambisa nokunamathela kodaka ngesikhathi sokwakha.

Thuthukisa ukunamathela kanye nokulwa nokugoba: I-HEMC inikeza amandla okubopha afanele kanye nokunamathela ukuze kuvinjelwe ukuthi udaka lungagobi ngemva kokufutha.

Thuthukisa ukusebenza kokwakha: Yenza udaka lube lula ngesikhathi sokufutha, ukupompa kanye nokulinganisa, futhi uthuthukise ukusebenza kahle kokwakha.

Kuzinzile ekushiseni, e-asidi nase-alkali: Kufanelekile ezimweni ezahlukene zemvelo ukuqinisekisa ukusebenza kahle kodaka.

3. Indima ethile ye-HEMC ku-spray mortar

3.1. Thuthukisa izakhiwo ze-rheological zokwakha

Ukusebenza kahle kwe-spray mortar kudinga ukuthi ibe nokugeleza okuhle kanye ne-thixotropy ezinzile. I-HEMC ingalungisa ukuhambisana kwe-mortar, okwenza kube lula ukuyipompa nokufutha. Ngesikhathi esifanayo, ingashesha ukujiya ngemva kokufutha odongeni, ithuthukise ukusebenza kokulwa nokuwa, futhi iqinisekise ukumbozwa okufanayo kwe-mortar kanye nobukhulu bokwakha obuhambisanayo.

3.2. Thuthukisa ukugcinwa kwamanzi futhi wandise isikhathi sokuvula

Ngesikhathi sokufafaza, amanzi kulula ukuwasha ngokushesha, ikakhulukazi ngaphansi kwezimo zokushisa okuphezulu noma zokungenisa umoya, okungabangela kalula ukuqhekeka kwe-mortar noma ukubopha okubi. Ukusebenza kahle kokugcinwa kwamanzi kwe-HEMC kubambezela ngempumelelo ukulahleka kwamanzi, kuqinisekisa ukuthi usimende nezinye izinto ezifaka u-cement zimanzi ngokuphelele, futhi kuthuthukisa amandla okubopha phakathi kwe-mortar nesisekelo. Ngesikhathi esifanayo, ukwandisa isikhathi sokuvula kusiza ekulinganisweni noma ekuqedeni okulandelayo, futhi kuthuthukisa ukuguquguquka kokwakha.

3.3. Thuthukisa ukuvimbela ukugoba nokubopha

Uma wakha phezu kwezindawo eziqondile noma izindonga eziphakeme, uma udoti umanzi kakhulu, kulula ukugoba, okuthinta ukubukeka nokulawulwa kobukhulu. I-HEMC yandisa ukujiya nokuhlangana ukuze yenze udoti ube ne-thixotropy enhle, okungukuthi, umanzi kahle uma uphoqwa (ukupompa noma ukufutha), ubuyisela ngokushesha ukuqina uma umile, unamathela ngokuqinile odongeni, futhi uvimbela ngempumelelo ukugoba.

3.4. Thuthukisa ukuzinza kwe-mortar

I-HEMC ingazinzisa ukusabalala kwezinto ezisebenzisa ukhonkolo kanye nama-aggregates ohlelweni lwe-mortar, ivimbele ukuhlukaniswa nokuphuma kwamanzi, iqinisekise ukufana kwengxube ye-mortar, futhi ithuthukise ikhwalithi yokwakha iyonke.

4. Isilinganiso kanye nokusetshenziswa kwe-HEMC

Inani elinconywayo lokwengeza ku-spray mortar ngokuvamile liyi-0.2% kuya ku-0.6%, kuye ngokuthi ifomula, inhloso kanye nokusebenza okudingekayo kwe-mortar. I-HEMC ifakwa ku-mortar eyomile ngesimo sempuphu eyomile, ixutshwe ngokulinganayo nezinye izinto zokusetshenziswa, bese ivuselelwa ngamanzi ukuze isetshenziswe. Inomswakama omuhle kakhulu, kulula ukuyihlakaza, ayikhiqizi ukuhlangana, futhi ilungele ukukhiqizwa kwezimboni kanye nokusetshenziswa endaweni.

5. Isibonelo somphumela wohlelo lokusebenza

Ukusetshenziswa kwe-HEMC ku-plastering yangaphandle yodonga kungandisa kakhulu ubukhulu bodonga kanye nekhono lokulenga i-slurry yodaka, futhi kunciphise ukulahlekelwa komhlabathi wokwakha. Ku-thermal insulation mortar, i-HEMC ithuthukisa amandla okubopha phakathi kwezinto kanye nesendlalelo sesisekelo, iqinisekisa ukuzinza okuphelele nokuqina kohlelo lokuvikela ukushisa. Impendulo yangempela yephrojekthi ikhombisa ukuthi i-spray mortar ene-HEMC eyengeziwe ilula ukuyakha, umphumela ubushelelezi futhi uthambile, futhi izinga lokuvuselela ukwakhiwa liyancipha.

Njenge-cellulose ether esebenza kahle kakhulu,i-hydroxyethyl methylcellulose idlala indima ebalulekile ekuqineni nasekugcinweni kwamanzi, ukuzinza kanye nokusiza ekwakheni udaka lokufafaza, okuthuthukisa kakhulu ukusebenza kokufafaza ngomshini kanye nekhwalithi yomkhiqizo oqediwe wodaka. Ngokukhuthazwa kokuzenzakalela kwesakhiwo kanye nokwakhiwa okuluhlaza, ukusetshenziswa kwe-HEMC emkhakheni wodaka oluxutshwe kusengaphambili kuzoba kukhulu kakhulu, kube yisikhuthazo esibalulekile ekuthuthukisweni kobuchwepheshe bezinto zokwakha.
