Esinye sezithasiselo ezisetshenziswa kakhulu odakeni lwengxube eyomile i-hydroxyethyl cellulose (HEC). I-HEC iyi-ether ye-cellulose engeyona i-ionic enokuqina, ukugcinwa kwamanzi, ukuqiniswa, kanye nezakhiwo zokumiswa. Isetshenziswa kabanzi ezintweni zokwakha, ikakhulukazi odakeni lwengxube eyomile.
1. Iqhaza le-HEC kudaka lwengxube eyomile
Ngodaka oluxubene elomile, i-HEC idlala indima enkulu yokugcina amanzi, ukujiya kanye nokwenza ngcono ukusebenza kokwakha:
Ukugcinwa kwamanzi: I-HEC inokugcinwa kwamanzi okuhle kakhulu futhi inganciphisa ukulahleka kwamanzi. Lokhu kubaluleke kakhulu odakeni lwengxube eyomile ngoba kwandisa isikhathi esivulekile sodaka, okuvumela abasebenzi ukuthi balungise udaka isikhathi eside futhi bathuthukise ukusebenza kahle kokwakhiwa. Ngaphezu kwalokho, ukugcinwa kwamanzi kunganciphisa ingozi yokuqhekeka futhi kuqinisekise ukuthi inqubo yokuqina kodaka ifana kakhulu futhi izinzile.
Ukuqina: Umphumela wokuqina we-HEC unikeza udaka i-viscosity enhle, okuvumela udaka ukuthi unamathele kangcono ebusweni be-substrate ngesikhathi sokwakha, akulula ukushelela, futhi uthuthukise ukufana kwesicelo. Lesi sici sibaluleke kakhulu ekwakhiweni okuqondile futhi singathuthukisa kakhulu izinga lokwakhiwa kodaka.
Thuthukisa ukusebenza kokwakhiwa: I-HEC ingenza udaka oluxutshwe okomile lube bushelelezi futhi lube lula ukulusebenzisa, ngaleyo ndlela lunciphise ubunzima bokusebenza. Kwenza udaka lube nokusabalala okuhle kakhulu nokunamathela ku-substrate, okwenza ukwakhiwa konge abasebenzi futhi kuthuthukise ukusebenza kahle komsebenzi. Ngaphezu kwalokho, kungase futhi andise ikhono anti-sagging, ikakhulukazi ekwakhiweni ungqimba obukhulu.
2. Indlela yokukhetha ye-HEC
Lapho ukhetha i-HEC, izici ezifana nesisindo sayo samangqamuzana, izinga lokushintshwa kanye nokuncibilika kufanele kucatshangelwe, okuzothinta ngokuqondile ukusebenza kodaka:
Isisindo samangqamuzana: Ubukhulu besisindo samangqamuzana buthinta amandla okuqina kanye nomphumela wokugcina amanzi we-HEC. Ngokuvamile, i-HEC enesisindo esikhulu samangqamuzana inomphumela ongcono wokuqina, kodwa izinga lokuqedwa elihamba kancane; I-HEC enesisindo samangqamuzana amancane inezinga lokuqedwa ngokushesha kanye nomphumela wokujiya othe ukubi kakhulu. Ngakho-ke, kuyadingeka ukukhetha isisindo esifanele samangqamuzana ngokuya ngezidingo zokwakha.
Izinga lokushintsha: Izinga lokushintshwa kwe-HEC linquma ukunyibilika kwayo kanye nokuzinza kwe-viscosity. Ukuphakama kwezinga lokushintshwa, kungcono ukuncibilika kwe-HEC, kodwa i-viscosity izokwehla; lapho izinga lokushintsha liphansi, i-viscosity iphakeme, kodwa ukuncibilika kungase kube kubi. Ngokuvamile, i-HEC enezinga elilinganiselwe lokushintsha ifaneleka kakhulu ukusetshenziswa odakeni oluxutshwe okomile.
Ukunyibilika: Izinga lokuqedwa kwe-HEC lithinta isikhathi sokulungiselela ukwakhiwa. Ngodaka oluxutshwe okomile, kuhle kakhulu ukukhetha i-HEC okulula ukuyihlakaza nokuhlakazeka ngokushesha ukuze kuthuthukiswe ukuguquguquka kokwakhiwa.
3. Izinyathelo zokuqapha lapho usebenzisa i-HEC
Lapho usebenzisa i-HEC, udinga ukunaka inani layo elingeziwe kanye nezimo zokusetshenziswa ukuze uqinisekise umphumela omuhle kakhulu:
Ukulawulwa kwenani elingeziwe: Inani elingeziwe le-HEC livame ukulawulwa phakathi kuka-0.1% -0.5% wesisindo esiphelele sodaka. Ukwengeza ngokweqile kuzobangela ukuthi udaka lube lukhulu kakhulu futhi luthinte uketshezi lokwakha; Ukwengeza okunganele kuzonciphisa umphumela wokugcina amanzi. Ngakho-ke, ukuhlolwa kufanele kwenziwe ngokwezidingo zangempela ukuze kutholwe inani eliphelele lokwengeza.
Ukuhambisana nezinye izithasiselo: Ngodaka oluxutshwe okomile, i-HEC ivame ukusetshenziswa ngokuhlanganiswa nezinye izithasiselo ezifana ne-redispersible latex powder, i-cellulose ether, njll. Naka ukuhambisana kwe-HEC nezinye izithako ukuqinisekisa ukuthi akukho ukungqubuzana nokuthinta. umphumela.
Izimo zokugcina: I-HEC i-hygroscopic, kunconywa ukuyigcina endaweni eyomile futhi ugweme ukukhanya kwelanga okuqondile. Kufanele isetshenziswe ngokushesha ngangokunokwenzeka ngemva kokuvula ukuvimbela ukuwohloka kokusebenza.
4. Umphumela wokusetshenziswa kwe-HEC
Ekusetshenzisweni okungokoqobo, i-HEC ingathuthukisa kakhulu ukusebenza kokwakhiwa kodaka oluxutshwe okomile futhi ithuthukise ikhwalithi iyonke yodaka. Ukuqina nokugcinwa kwamanzi umphumela we-HEC kwenza udaka oluxubekile lube nokunamathela okuhle nokuzinza, okungagcini nje ukuthuthukisa ikhwalithi yokwakha, kodwa futhi kwandise isikhathi esivulekile sodaka, okuvumela abasebenzi ukuthi basebenze ngokuthula. Ukwengeza, i-HEC inganciphisa ukuvela kokuqhekeka ebusweni bodaka, okwenza udaka oluqinile luhlale luqinile futhi luhle.
5. Ukuvikelwa kwemvelo kanye nomnotho we-HEC
I-HEC iwukuphuma kwe-cellulose evumelana nemvelo ebolayo futhi ehambisana nemvelo. Ukwengeza, i-HEC inenani elilinganiselwe futhi iyabiza, okwenza ifanelekele ukukhuthazwa okusabalele kanye nokusetshenziswa ezinhlotsheni ezihlukahlukene zamaphrojekthi wokwakha. Ukusetshenziswa kwe-HEC kunganciphisa isilinganiso samanzi nosimende wodaka, ngaleyo ndlela kuncishiswe ukusetshenziswa kwamanzi, okubuye kuhambisane nendlela yamanje yokuvikelwa kwemvelo eluhlaza embonini yezokwakha.
Ukusetshenziswa kwe-HEC odakeni oluxutshwe okomile kungathuthukisa kakhulu ukusebenza kodaka futhi kuyisengezo esibalulekile ekwakheni. Ukugcinwa kwawo kahle kwamanzi, ukujiya kanye nokuvumelana nezimo zokwakha kuthuthukisa ukusebenza kahle kokwakhiwa futhi kwenza ikhwalithi izinze kakhudlwana. Ukukhetha
i-HEC efanele futhi ukuyisebenzisa kahle ayikwazi nje ukuthuthukisa ikhwalithi yokwakha, kodwa futhi ihlangabezane nokuvikelwa kwemvelo kanye nezidingo zezomnotho.
