Njengesengezo sokwakha esibalulekile, i-ether ye-cellulose isetshenziswa kabanzi embonini yezokwakha, ikakhulukazi kuma-tutties kanye nokumboza. Izakhiwo zayo zamakhemikhali ezihlukile nemisebenzi zikwenza kube yisithako esibalulekile ekuthuthukiseni ukunamathela kwe-putty ku-substrate ehlukahlukene. Imisebenzi esemqoka ye-Celsulose 'TETERS ifaka phakathi ukuqina, ukugcinwa kwamanzi, ukumiswa kanye nokunamathela okuthuthukisiwe. Ukungeza i-cellulose err kwifomula yama-putty kungathuthukisa kakhulu ukusebenza kokusebenza kwe-putty futhi kuthuthukise ukunamathela kwalo ku-substrate.
1. Izici ze-cellulose ether kanye nendlela yesenzo se-putty
I-Celsulose Ether uhlobo lokususelwa kweselula yemvelo eyakhiwe ngemuva kokuguqulwa kwamakhemikhali, ikakhulukazi ihlukaniswe nge-methyl cellulose (i-hpmc), i-hpmpypropyl methyl cellulose (HPMC), i-HydroxYethyl cellulose (i-njll), njll. Ama-molecule we-cellulose ether ane-soubelity yamanzi enhle kanye nezakhiwo eziqina, futhi angakha izixazululo ezinzile ze-colloidal uma zixutshwe namanzi. Kusukela ama-molecule we-cellulose ether anamaqembu ama-hydrophilic kanye nama-hydrophobic, ukuboya kwawo kanye nokubonana kwamanzi kungathuthukisa ukusebenza ngempumelelo kwezokwakha zikaPutty.
Indlela yokwenza isenzo se-cellulose ether ngesi-putty ibonakala ikakhulu kulezi zinto ezilandelayo:
Ukugcinwa kwamanzi: I-Cellulose Ether ingadlala indima enhle kakhulu yokugcina amanzi efomula yamanzi futhi ivikele amanzi ukuthi avele ngokushesha ngemuva kokwakha. Lokhu kuvumela ukubeka ukusabalalisa umswakama ngokulinganayo ngesikhathi senqubo yokomisa, ngaleyo ndlela kunciphisa ukuqhekeka nokusiza ukuthuthukisa ukunamathela kukaPutty ku-substrate.
Ukuqina Lesi sici sibalulekile ekusetshenzisweni kwesicelo nokwakha se-Putty.
Ukugcona: I-cellulose ether ingathuthukisa ukugcotshwa kwama-putty, okwenza ukwakhiwa kube lula, kunciphise ukumelana ngesikhathi sokwakha, futhi ngaleyo ndlela kufanelwe kangcono impahla eyisisekelo.
I-Anti-SAG: I-cellulose ether inomphumela wokuthuthukisa ukunxusa kwe-putty, okwenza ama-putty amancane amathuba okuthi akwazi ukugcwala ngesikhathi sokwakha, futhi akwazi ukunamathela ngempumelelo ekushiseni okuphezulu, okuphezulu kakhulu. Umphumela wokunamathela.
2. Umphumela we-cellulose ether ku-tutty adhesion
Ukunamathela kwe-putty kuyisici esibalulekile esithinta umphumela waso wokwakha kanye nempilo yenkonzo. Ukungezwa kwe-cellulose ether kunikeza ama-putty izinzuzo ezilandelayo zokunamathela:
Thuthukisa ukunganakwa kwendawo engaphezulu kwe-substrate Lo mthelela omanzi uthuthukisa amandla okungena kwe-putty, okwenza kube lula ukuthi u-putty ungene ungene kuma-pores amancane we-substrate, ethuthukisa ukunamathela kwemishini.
I-Adhesion ethuthukisiwe: Imiphumela yokuqina nokugcina amanzi ye-cellulose ether inika amandla i-putty ukwakha isendlalelo sembozo esilinganayo ebusweni be-substrate, ngaleyo ndlela ithuthukise ukunamathela komzimba. Lo msebenzi awukwazi ukuvikela kuphela i-putty kusuka ekunciphiseni ngesikhathi senqubo yokwelapha, kepha futhi ivikele ukwakheka kwezikhala phakathi kwe-putty kanye nesisekelo sokwenza izisekelo.
Ukuphikiswa kokuqhekeka okuthuthukile: kungathuthukisa ukuguquguquka kwe-putty futhi kunciphise ukucindezela ku-putty ungqimba olubangelwa izinguquko ekushiseni nasekuthwalweni komswakama, ngaleyo ndlela kugwemeke ukuqhekeka. Lokhu kuguquguquka kuvumela ukucindezelwa kwangaphakathi okwenziwe yi-putty ngesikhathi senqubo yokomisa ukumunca futhi kuhlakazeke, ngaleyo ndlela kuthuthukise ukunamathela phakathi kwesipuni kanye ne-substrate.
Thuthukisa ukumelana nesimo sezulu Ngaphansi kwezimo ezinzima njengokushisa okuphezulu kanye nomswakama ophansi, izinga lokuhwamuka kwamanzi engxenyeni ye-tutty yehlisa, kuqinisekiswe umphumela wokunamathela we-putty.
3. Ukusetshenziswa kwezindlebe ze-cellulose kuma-substrate ahlukene
Ama-substrates ahlukene anezidingo ezihlukile zokunamathela kwe-putty. Ukungezwa kwe-cellulose ether kungathuthukisa kakhulu ukunamathela kwe-putty ku-substrate evamile elandelayo:
Indwangu yesisekelo somuntu I-Cellulose Ether ingathuthukisa ukunamathela kwesipuni kuya kwesisekelo sokwenza usimende
I-Gypsum Base Mate: Ingaphezulu le-gypsum base mature bushelelezi, futhi imiphumela yokuqina kanye nokugcina amanzi ye-cellulose ether ingasiza i-putty yakha umfaniswano wokuhlangana emfaniswano ku-gppsum base mature noma ukuqhekeka.
I-Wood Substrate: Izinkuni zinokufakwa kwamanzi okuqinile kanye nezakhiwo ze-shrinkage. Ukungezwa kwe-cellulose ether kungathuthukisa ukuguquguquka nokugcinwa kwamanzi kokubeka futhi kuvikele ungqimba lwe-tutty kusuka ekuweni ngenxa yokuphela kwezinkuni.
I-Metal Substrate: Ingaphezulu lensimbi libushelelezi futhi lingamuzwanga, okwenza kube nzima ukunamathela, kepha i-etherther ether ingakhuphula ukunamathela kwe-putty ebusweni bensimbi, okuvumelayo.
Ukungezwa kwe-cellulose ether kuthuthukisa kakhulu ukunamathela kwe-putty, okwenza kube lulungele ama-substrates ahlukahlukene. Ngemisebenzi eminingi efana nokuqina, ukugcinwa kwamanzi, ukuthambisa kanye nokuthuthukisa ukuguquguquka, izithambiso ze-cellulose zithuthukisa ngempumelelo ukusebenza kwe-putty ekwakheni, ukwelula impilo yayo yensiza futhi kunciphise izindleko zokulungisa. Ngakho-ke, i-cellulose ether iba yinto ebaluleke kakhulu engokhiye ekwakhiweni kwamanje, ukuhlinzeka ngezinto zokwakha ezinama-adhesion aqinile nokuqina.
