Ukusetshenziswa kwe-hydroxyethyl celtulose ku usimende kanye nodonga putty

IHydroxYethyl Cellulose (I-HEC) iyingxenye ebalulekile ye-polymer esetshenziswayo esetshenziswa kabanzi kwezinto zokwakha. Ngenxa yokuqina kwayo okuhle kakhulu, ukugcinwa kwamanzi kanye nezakhiwo ezenziwe ngefilimu, i-hec ikhombisa imiphumela ebalulekile yokuguqulwa ku-Cument nodonga lwe-Pumpty.

1.Charoctis of Hydroxyethyl cellulose

I-Hydroxyyethyl celtulose iyi-ether engekho i-ether etholwa ngokuphendula i-cellulose nge-ethylene oxide. Izici zalo eziphambili zifaka:
I-Solubinity yamanzi: I-HEC ingancibilika ngokushesha emanzini abandayo ukwakha uketshezi olusobala lwe-viscous.
Ukuqina: I-HEC ingakhulisa ngempumelelo ukubonwa kwesixazululo.
Ukugcinwa kwamanzi: Kungabambezela ukuhwamuka kwamanzi, ngaleyo ndlela kuthuthukise ukusebenza kokusebenza kwezinto.
Ukumiswa: I-HEC ingamisa ngokulinganayo izinhlayiya futhi ivikele ukuqunjelwa.
Izakhiwo ezenziwe ngefilimu: Isixazululo se-HEC singakha ifilimu esobala ngobunzima obuhle.
Lezi zakhiwo zenza i-hydroxyethyl cellulose ibe isengezo esifanelekile ezintweni zokwakha ezifana nesimende naku-putty.

2. Ukusetshenziswa kwe-hydroxyethyl celtulose ku usimende

Thuthukisa ukusebenza kokwakha
Ezintweni ezisetshenziswayo kasimende, amakhono okuqina we-HEC kanye namanzi angathuthukisa kakhulu ukusebenza kokwakha. Isibonelo, ngesikhathi sokulungiswa noma izinqubo zokupenda, ama-slielies usimende angezwe nge-HEC anokusebenza okungcono nokugcinwa kwamanzi. Lezi zakhiwo zivimba lokho okuqukethwe ekumiseni ngaphambi kwesikhathi ngesikhathi sokwakha, ngaleyo ndlela kunciphise ukwakheka kwemifantu kanye nokwenza ngcono ikhwalithi yokwakha.

Thuthukisa ukumelana nokuqhekeka
Izakhiwo ezigcina amanzi ze-HEC zisiza ukugcina ukusatshalaliswa komswakama okufanayo ngesikhathi sokuqinisa usimanzi futhi kunciphise ukwenzeka kokuqhekeka kwe-shrinkage. Ngasikhathi sinye, i-HEC inyusa i-viscosity ka usimende Slurry, ukuvumela ukuhlanganisa okungcono nokuxhasa ama-aggregates, ngaleyo ndlela kuthuthukise ukumelana nokuqhekeka kwezinto zokwenziwa kosimende.

Thuthukisa ukunamathela
Izakhiwo ezibophayo ze-HEC zingathuthukisa isibopho phakathi kosimende nezinye izinto, ezinjengesimende nezitini noma i-gypsum board. Lokhu kubaluleke kakhulu ekuthuthukiseni ukuqina nokuqina kwesakhiwo sonke.

3. Ukusetshenziswa kwe-Hydroxyethyl celtulose edongeni uPutty

Umphumela wokuqina
E-Wall Putty, umphumela wokuqina we-HEC wenza i-putty ibe nokubonakala okufanele, ngaleyo ndlela yenza lula imisebenzi yokwakha. Umphumela omuhle wokuqina wenza uPutty asetshenziswe ngokulinganayo odongeni ngaphandle kokugcoba noma ukunqwabelana.

Thuthukisa ukugcinwa kwamanzi
Izakhiwo ezigcina amanzi ze-Putty zibalulekile kwikhwalithi yayo yokwakha. I-HEC ingabambezela ukuhwamuka kwamanzi futhi iqinisekise ukuthi i-Putty inoMswakama owanele ngesikhathi senqubo yokwelapha, ngaleyo ndlela ithuthukise amandla nokuqina kwesipuni. Ikakhulu ezindaweni ezomile, umphumela wokugcinwa kwamanzi we-HEC ungathuthukisa kakhulu ukusebenza kwe-tutty futhi uyivimbele ekumisweni ngaphandle.

Thuthukisa ukusungulwa
Ukusetshenziswa kwe-HEC ku-tutty kungathuthukisa ubushelelezi kanye nokugcwala kwezinto ezibonakalayo, okwenza ukwakhiwa kukaPutty kube bushelelezi. Ngasikhathi sinye, ngoba i-HEC ingamisa ngempumelelo izinhlayiya ze-filler ku-putty futhi ivikele ekuxazululeni, i-putty igcina ukusebenza okuzinzile ngesikhathi sesitoreji.

Thuthukisa ikhwalithi ephezulu
I-HEC idlala indima ebondisayo nezobumba e-putty, evumela ukuthi i-putty ukwakha indawo ebushelelezi futhi eminyene ngemuva kokuphulukisa. Lobuso abulula nje kuphela esihlabathini, kodwa futhi uhlinzeka ngethonya elihle lokuhlobisa, ukuhlinzeka ngesisekelo esihle semisebenzi yokupenda elandelayo.

4. Ukungeza inani kanye nendlela yokusebenzisa ye-hydroxyethyl cellulose

Kuzinhlelo zokusebenza ezisebenzayo, inani lokungezwa le-hydroxyethyl celtulose livame ukulawulwa phakathi kuka-0,1% no-0.5%. Inani elithile lidinga ukulungiswa ngokuya ngezakhiwo zezidingo zezinto nezicelo. I-HEC imvamisa ingezwe ku-Cement noma ku-putty mixtures nge-powder noma ifomu le-granular. Ukuqinisekisa ukusakazwa kwayo, i-HEC ivame ukuxutshwa nenani elincane lamanzi ukwakha ikhambi le-colloidal ngaphambi kokuba lixube nezinye izinto.

5. Lapho usebenzisa i-HEC, udinga ukunaka amaphuzu alandelayo:

Inqubo yokuqothula: Izinga lokuchithwa kwe-HEC lithintwa ukushisa kwamanzi kanye nesivinini esishukumisayo. Lapho usebenzisa amanzi abandayo, ukunweba ngokufanele isikhathi sokuvuselela ukuqinisekisa ukuchithwa okuphelele kwe-HEC.
Ukuxuba ukulandelana: ukugwema i-HEC ukwakha ama-clumps, i-HEC kufanele ichithwe emanzini kuqala ngaphambi kokungeza ezinye izinto.
Izimo Zokugcina: I-HEC kufanele igcinwe endaweni eyomile nepholile, kude nomswakama noma amazinga okushisa aphezulu.

6. Izibonelo zohlelo lokusebenza

udonga uPutty
Ku-Wall Putty, Ukungeza i-HEC kungathuthukisa ngempumelelo ukusebenza kokwakha kanye nekhwalithi ephezulu ye-putty. Isibonelo, kuphrojekthi ethile, engeza i-HEC engu-0.2% yanweba isikhathi sokusebenza se-putty cishe imizuzu engama-30, futhi ingaphezulu le-putty eyomile lalilihlekile futhi elingenamsoco, linikeza isisekelo esihle sokuhlobisa okulandelayo.

usimende ozimilekile
Ukusetshenziswa usimende ozimisele ukuzimela, i-HEC ingathuthukisa ukubonwa nokugcinwa kwamanzi okubuyiselwa kwamanzi, okuvumela i-CEAND ukuthi ilondoloze uketshezi oluhle nokufana ngesikhathi senqubo yokuzenzela. Isibonelo, ephrojekthi ethile yezinga eliphansi, engeza i-0.3% hec ngcono kakhulu i-fluidity kanye nekhono lokuzenzela le-slurry kasimende. Ngemuva kokwakhiwa, umhlabathi wawubushelelezi futhi kwakungekho kusobala okusobala ukuqhekeka.

Njengesengezo esisebenzayo esiningi, i-hydroxyyethyl celtulose ikhombisile imiphumela yesicelo enhle kakhulu ku-Cument ne-Wall Putty. Ukuqina kwalo, ukugcinwa kwamanzi, kanye nezakhiwo ezithuthukisiwe zokunamathela kungagcini nje ngokuthuthukisa ukusebenza kokwakha kanye nekhwalithi ephezulu, kodwa futhi kuthuthukisa kakhulu ukumelana nokuqina kokuqina kwezinto ezibonakalayo nokuqina. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe bokwakha ubuchwepheshe, i-HEC izodlala indima ebaluleke kakhulu ezinhlelweni zokwakha ezizayo.
