Udaka lwempushana eyomile lusetshenziswa kabanzi njengamanje. Kukhona inkomba yamandla ebhondi odakeni lwempushana eyomile. Ngokombono wezinto ezibonakalayo, lapho into ifuna ukunamathela kwenye into, idinga i-viscosity yayo. Kungokufanayo nangodaka, usimende +Isihlabathi esixutshwe namanzi ukuze kuzuzwe amandla ebhondi yokuqala, bese welapheka ngezithako nosimende ukuze ekugcineni kuzuzwe amandla ebhondi adingwa udaka. Ngakho yiziphi izici ezithinta amandla esibopho?
Umphumela wezithasiselo
I-Cellulose ether kanye nempushana yerabha izithasiselo ezibalulekile odakeni oluhlanganisa impushana eyomile. Impushana yerabha esesimendeni ngokuvamile iyimpushana ye-latex encibilika emanzini, engahlukaniswa ibe eqinile futhi evumelana nezimo. Sebenzisa impushana yerabha ehambisanayo ngokwezidingo zomkhiqizo; imisebenzi eyinhloko Inikeza ukunamathela okuhle kakhulu futhi isiza ukuthuthukisa ukumelana namanzi, ukumelana nokushisa, ipulasitiki kanye nokuguquguquka kodaka.
Indima ye-cellulose ether isetshenziselwa ikakhulukazi ukugcinwa kwamanzi odakeni ukuze kuthuthukiswe ukwakhiwa komkhiqizo; isibonelo, lapho bakha indlu ngaphambili, izingcweti eziningi zazixuba usimende nesihlabathi phansi. Ngemva kokufaka amanzi nokunyakazisa, ngokuvamile babona amanzi egeleza. Uma unamathisela udonga ngalolu hlobo lodaka, akufanele nje lube lukhulu, kodwa futhi inani elincane kufanele lisetshenziswe kancane kancane. Esinye isimo esokusula ngenkathi uhlikihla. Ukuthuthukiswa kulezi zimo kwakushesha. Amanzi avalelwe odakeni futhi enqaba ukukhipha. Lapho unamathisela udonga, lungakhiwa kalula njenge-putty, futhi ubukhulu bungabuye bulawuleke futhi buncishiswe; inzuzo enkulu ukuthi ijubane lokumisa lodaka lingalawulwa ngokuphumelelayo, futhi usimende ungaba namanzi ngokugcwele, okuzuzisa ekuthuthukisweni okuphelele kwamandla odaka.
shwabana
Ukuncipha kodaka kungashiwo ukuthi kuhambisana namandla okubopha, okungathinta indawo yangempela yokubopha, ngaleyo ndlela yakhe imifantu engenalutho futhi ilahlekelwe ngokuqondile amandla okubopha; ngakho-ke, kufanele sibe nezidingo eziqinile ekufakweni kukasimende nesihlabathi odongeni , okungagcini nje ukulawula ukuncipha, kodwa futhi kunomthelela emandleni esibopho sodaka. Ngaphezu kwalokho, ukunciphisa ukuncipha kungabuye kuhlanganiswe nezinto ezisebenzayo. Izinto ezisebenzayo ngokuvamile zibhekisela enanini elikhulu le-silica ecushiwe kanye ne-alumina ecushiwe. Ayiqini noma iqine kancane kakhulu lapho amanzi engezwa. Usayizi wayo wezinhlayiyana ucolekile, ongangena esikhundleni sengxenye yodaka lokugcwalisa usimende, ngaleyo ndlela unciphise ukushwabana okuphelele kodaka.
Umthelela wokungangeni manzi kanye ne-hydrophobic
Ngomqondo othile, ukuvimbela amanzi kanye ne-hydrophobicity kungqubuzana namandla ebhondi. Isibonelo, esikhathini esidlule, abantu abaningi babenethemba lokuba nezindawo ezingenawo amanzi kuma-adhesive tile, ezinganciphisa inqubo yokwakhiwa kwezindonga zekhishi nezokugezela, kodwa okwenzekayo akuphakeme; okokuqala, uma udaka lwethu lufuna ukufeza imiphumela engenamanzi noma ye-hydrophobic, kufanele sengeze i-agent ye-hydrophobic. Ngemuva kokuthi i-agent ye-hydrophobic ixutshwe nodaka, ifilimu engenakunyakaziswa izokwakhiwa kancane kancane phezulu. Ngale ndlela, lapho amathayela enamathiselwe, amanzi awakwazi ukungena ngokuphumelelayo kumathayela, amandla okumanzisa ayancishiswa, futhi amandla okubopha emvelo awakwazi ukuthuthukiswa ngesikhathi sokulungiswa kodaka okwalandela.
Amandla okubopha abhekisela kumandla amakhulu okubopha odaka asebenza kungqimba olungezansi;
Amandla okuqina asho ikhono lendawo yodaka ukumelana namandla aqinile abheke phezulu;
Amandla okugunda asho amandla anqunywa ngokusebenzisa amandla ahambisanayo;
Amandla acindezelayo asho inani eliphakeme lapho udaka luhluleka khona, likalwa ngokusebenzisa ukucindezela.
