I-Cellulose ether iyinto ebalulekile yamakhemikhali esetshenziswa kabanzi kumpuphu yodaka kumaphrojekthi wokwakha. Iwuhlobo lokuphuma kwe-cellulose oluguqulwa ngamakhemikhali ngamaqembu e-hydroxyl kuma-molecule e-cellulose, okuhlanganisa i-hydroxypropylmethylcellulose (HPMC), i-methylcellulose (MC), i-hydroxyethylcellulose (HEC), njll. Lawa ma-cellulose ethers anemisebenzi eyahlukene kanye nezakhiwo ezinhle kakhulu, okuwanika izinzuzo eziphawulekayo emazingeni okwakha.
(1) Thuthukisa ukusebenza komsebenzi wokwakha
1. Thuthukisa ukusebenza
Ama-cellulose ether asebenza njengama-thieners nama-ejenti agcina amanzi odaka. Ingakwazi ukuthuthukisa i-viscosity kanye ne-thixotropy yodaka, okwenza kube lula ukusabalalisa nokushelela, ngaleyo ndlela kuthuthukise ukunethezeka nokusebenza kahle kokwakhiwa. Ngaphezu kwalokho, i-cellulose ether ingavimbela udaka ekuhlukaneni phakathi nenqubo yokwakha, iqinisekise ukufana nokunamathela okungcono kodaka.
2. Thuthukisa ukunamathela kodaka
I-cellulose ether ingathuthukisa kakhulu ukunamathela kodaka ku-substrate. Lokhu kubaluleke kakhulu ezinqubweni ezinjengokufaka amathayela noma ukuplasta ezidinga isibopho esiqinile ne-substrate. I-Cellulose ether ivumela udaka ukuthi lugcine izakhiwo ezinhle zokunamathela ezindaweni ezinomswakama noma ezomile, ukugwema izinkinga zokuchitha nokuqhekeka okubangelwa ukunamathela okwanele.
(2) Thuthukisa izici ezibonakalayo zodaka
1. Thuthukisa ukugcinwa kwamanzi
Ukugcinwa kwamanzi kungenye yezinto ezibalulekile ze-cellulose ether, evumela udaka ukuthi lugcine umswakama owanele ngaphambi kokuqina. Lesi sici singavimbela ukuhwamuka kwamanzi ngaphambi kwesikhathi futhi sinciphise ukulahlekelwa kwamanzi odakeni, ngaleyo ndlela sithuthukise ukufaneleka kokusabela kwe-cement hydration futhi sikhuthaze ukuthuthukiswa kwamandla nokuqina kodaka.
2. Lungiselela amandla odaka
Ngomphumela wokugcina amanzi we-cellulose ether, usimende osodakeni ungafakwa ngokuphelele emanzini ukuze ukhiqize umkhiqizo onamandla wokukhipha amanzi. Lokhu kusiza ukuthuthukisa amandla okucindezela nokuguquguquka kodaka. Ngaphezu kwalokho, i-cellulose ether nayo inganciphisa imifantu ebangelwa ukuncipha kodaka ngesikhathi senqubo yokuqina futhi igcine amandla kanye nokuzinza kodaka.
3. Thuthukisa ukumelana neqhwa
Ama-cellulose ethers andisa ukuminyana kodaka, alwenze imelane kakhulu nemijikelezo yokuncibilika kweqhwa. Lokhu kumelana nokuncibilika kweqhwa kubaluleke kakhulu odakeni olusetshenziswa ezindaweni ezibandayo, ezinganweba ngempumelelo impilo yesevisi yesakhiwo futhi kunciphise izindleko zokulungisa.
(3) Ukuthuthukisa ukuguquguquka kwemvelo kokwakhiwa
1. Nweba amahora okuvula
Ama-cellulose ether anganweba isikhathi sokuvula udaka, okungukuthi, isikhathi udaka oluhlala lusebenza ngemva kokuba lubekwe. Lokhu kunenzuzo ikakhulukazi ekwakhiweni ekushiseni okuphezulu noma ezindaweni ezomile, kunciphisa inkinga yokuqina kodaka ngaphambi kwesikhathi okuthinta ikhwalithi yokwakha.
2. Thuthukisa ukumelana ne-sag
Uma wakha ezindaweni eziqondile, udaka luvame ukushelela noma ukucwila. I-Cellulose ether ithuthukisa ukusebenza kwe-anti-sag yodaka ngokujiya, iqinisekise ukuthi udaka lungaxhunywa ngokuzinza ezindaweni eziqondile futhi kugwenywe izinkinga zokwakha.
(4) Izinzuzo zemvelo nezomnotho
1. Thuthukisa ukusetshenziswa kwezinto ezibonakalayo
I-Cellulose ether ingathuthukisa kakhulu ukusebenza kanye nekhwalithi yokwakhiwa kodaka, futhi inciphise ukuchithwa kwezinto ngesikhathi sokwakha. Lokhu kunokubaluleka okubalulekile kwezomnotho ekwakhiweni kwenani elikhulu kumaphrojekthi wokwakha, okunganciphisa izindleko zempahla futhi kuthuthukise izinzuzo zezomnotho zokwakha.
2. Ayinandaba nemvelo
Ama-cellulose ethers ayizinto ezisekelwe ku-bio futhi anomthelela omncane emvelweni ngesikhathi sokukhiqizwa kwawo kanye nokusetshenziswa kwawo. Ngaphezu kwalokho, inganciphisa ngempumelelo ukungcola kwesibili ngesikhathi sokwakhiwa kodaka, njengothuli nemfucuza, futhi ihlangabezana nezidingo zezakhiwo eziluhlaza zanamuhla.
(5) Izibonelo eziqondile zohlelo lokusebenza
1. I-adhesive ye-tile
Ezinamathiselwe zamathayili e-ceramic, ukungezwa kwe-cellulose ether kungathuthukisa kakhulu ukusebenza, ukugcinwa kwamanzi namandla okubopha okunamathelayo, futhi kuthuthukise umphumela wokubopha kanye nokusebenza kahle kokwakhiwa kwamathayili e-ceramic.
2. Udaka olunameka odongeni
I-Cellulose ether kudaka lokuplasta ithuthukisa ukusebenza nokusebenza kwe-anti-sag kodaka, iqinisekisa ukushelela kanye nekhwalithi yangaphezulu yesendlalelo sokuplasta, futhi inciphisa ukukhubazeka kokwakhiwa nomsebenzi wokukhanda.
3. Udaka lokuzilinganisa
I-Cellulose ether odakeni oluzilinganisayo lusiza ukuthuthukisa ukugeleza kwamanzi nokugcinwa kwamanzi kodaka, okuwuvumela ukuthi uleveli phansi ngokuzenzakalelayo futhi uthuthukise ukucaba nokusebenza kahle kokwakhiwa komhlaba.
Kafushane, i-cellulose ether inezinzuzo ezibalulekile ekusetshenzisweni kwempushana yodaka kumaphrojekthi wokwakha. Akugcini nje ukuthuthukisa ukusebenza kokwakhiwa kanye nezakhiwo ezibonakalayo zodaka, kodwa futhi kuthuthukisa ukuguquguquka kwemvelo kanye nezinzuzo zezomnotho zokwakha. Ukusetshenziswa kwe-cellulose ether kuthuthukisa ikhwalithi nokuqina kodaka lokwakha futhi kukhuthaze ukuthuthukiswa okuqhubekayo kwamaphrojekthi wokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, i-cellulose ether izoba namathemba abanzi okusetshenziswa odakeni futhi ibe into ebalulekile nebalulekile ekwakheni kwesimanje.
