I-Cellulose ether iwuhlobo lwe-polymer material ekhiqizwa ngokushintsha amakhemikhali i-cellulose yemvelo. Isetshenziswa kabanzi ekwakhiweni, kwezemithi, ekudla, ekufakeni, ekunakekelweni komuntu siqu neminye imikhakha. Isakhiwo samangqamuzana esikhethekile se-cellulose ether siyinikeza izici eziningi eziyingqayizivele ngakho-ke sinezinzuzo ezisobala kanye nezinzuzo ezimbonini eziningi.
1. Ukuqina nokulawula i-rheology
Esinye sezici eziphawuleka kakhulu zama-cellulose ethers yikhono lawo elihle lokujiya. Ngemva kokuncibilika emanzini, i-cellulose ether ingakha isisombululo se-colloidal esifanayo futhi ikhulise ngempumelelo i-viscosity yesistimu. Lokhu kuvumela ukuthi ibambe iqhaza ekulawuleni uketshezi kanye nokwenza ngcono ukusebenza kwezinto zokwakha (ezifana nodaka, udaka) kanye nezingubo zokugqoka. Ngokulungisa umthamo kanye nohlobo lwe-cellulose ether, izakhiwo ezihlukene ze-rheological zingatholakala ukuhlangabezana nezidingo zezinhlelo zokusebenza ezahlukene. Isibonelo, kuma-mortars wokwakha, ama-cellulose ethers angavimbela izinto ekuhlukaniseni ngesikhathi sokuxuba, ukuqinisekisa ukufana kwezinto ngesikhathi sokwakhiwa nokugwema ukuqhekeka noma ukuwa.
2. Ukugcinwa kwamanzi
Enye inzuzo eyinhloko yama-cellulose ethers ngokusetshenziswa kwawo kabanzi ekwakheni umthamo wawo omuhle kakhulu wokugcina amanzi. Ingakhiya umswakama ezixubeni zempuphu ezomile ezifana nosimende negypsum, ngaleyo ndlela ibambezele ukuhwamuka kwamanzi endabeni. Ngodaka olusekelwe kusimende nezinto ezisekelwe ku-gypsum, ukugcinwa kwamanzi kwe-cellulose ethers kusiza ukuthuthukisa ukusebenza kahle kokusabela kwe-hydration, ukuqinisekisa ukuthi izinto zelashwa ngokugcwele futhi ziqinisiwe, ngaleyo ndlela kuthuthukisa amandla nokuqina kwesakhiwo. Ngesikhathi esifanayo, emazingeni okushisa aphakeme noma ezindaweni ezomile, ukusebenza kokugcinwa kwamanzi kwe-cellulose ether kubaluleke kakhulu ukuze kugwenywe ukuwohloka kwekhwalithi yokwakha ngenxa yokulahlekelwa kwamanzi.
3. Izakhiwo ezinhle zokwakha ifilimu
Ama-cellulose ethers anezakhiwo ezinhle kakhulu zokwakha ifilimu futhi asetshenziswa kakhulu embotsheni nasekunamathiseleni. Ingakha ifilimu efaniswayo neminyene endaweni yokumboza, engangeni manzi, ingangenisi uthuli kanye ne-anti-oxidation, kuyilapho ithuthukisa ukushelela kanye nokuqina kwengubo. Ezingxenyeni zezakhiwo, ama-cellulose ethers angathuthukisa ukunamathela nokumelana nokugqoka kwe-coating futhi andise impilo yayo yesevisi. Ukwengeza, izakhiwo ezenza ifilimu ze-cellulose ethers nazo zibaluleke kakhulu ekulungiseleleni imithi, ezingasiza izidakamizwa ukuba zenze izimbotshana zefilimu ukulawula amazinga okukhishwa kwezidakamizwa nokuthuthukisa ukuzinza kwezidakamizwa.
4. Ukumelana nokuhlaliswa nokumiswa
Ezinhlelweni eziwuketshezi ezinjengama-coatings nama-emulsions, i-cellulose ether ingasetshenziswa njengesiqinisi esisebenzayo ukuvimbela ukuhlaliswa kwezinhlayiya eziqinile. Ithuthukisa ukuzinza nokusetshenziswa komkhiqizo ngokwandisa i-viscosity yoketshezi nokugcina ukusatshalaliswa okufanayo kwezinhlayiya eziqinile. Isibonelo, kumapende asekelwe emanzini, i-cellulose ethers ingavimbela ngokuphawulekayo imvula ye-pigments noma izigcwalisi, igcine iyunifomu kapende futhi ithuthukise ukushelela kokwakhiwa.
5. Thuthukisa amandla okuxhumana
Emkhakheni wokwakha nokunamathisela, ukusetshenziswa kwe-cellulose ethers kungathuthukisa ngempumelelo amandla okubopha izinto, ikakhulukazi kuma-modified mortars. Iqhaza layo njenge-ejenti yokuqina kanye ne-ejenti egcina amanzi ingaqinisa ubudlelwano phakathi kodaka nezinto eziyisisekelo. Ukunamathela kodaka kunciphisa izinkinga zokuqhekeka nokuncipha kodaka. Ama-cellulose ether angaphinde alungise ngokuphumelelayo isikhathi sokuvula sokunamathela, aqinisekise isikhathi esanele sokulungiswa nokusikwa ngesikhathi sokwakha.
6. Thuthukisa ukusebenza komsebenzi wokwakha
Ama-cellulose ethers nawo athuthukisa ngokuphawulekayo izakhiwo zokwakha zezinto ezihlukahlukene zokwakha, ikakhulukazi kumasimende osimende kanye nezinto ezisekelwe ku-gypsum. I-rheology yayo ithuthukisa kakhulu ukusunduza, ukushelela kanye nokusebenza kalula ngesikhathi sokwakhiwa. Abasebenzi bokwakha bangasebenzisa izinto zokwakha kalula futhi banciphise ukunamathela kwamathuluzi kanye nokumosha izinto ezibonakalayo. Ukusetshenziswa kwe-cellulose ether nakho kuthuthukisa ukusebenza kwe-anti-sag yezinto ezibonakalayo, ukuqinisekisa ukuthi indawo ngemuva kokwakhiwa ibushelelezi futhi inhle.
7. Ukumelana nokushisa okuphezulu nokuzinza kwamakhemikhali
I-Cellulose ether inokuqina okuhle kokushisa kanye ne-inertness yamakhemikhali, evumela ukuthi igcine izakhiwo zayo ezingokwenyama namakhemikhali ngaphansi kwezimo ezihlukahlukene ezimbi kakhulu. Ama-cellulose ethers angamelana ngokuphumelelayo nokuwohloka emazingeni okushisa aphezulu, i-acid-base noma izindawo ze-oxidizing, ukuqinisekisa ukuqina nokuthembeka kwawo ekwakhiweni, embonini yamakhemikhali, ekhemisi nakweminye imikhakha. Lesi sici futhi senza ama-cellulose ethers asetshenziswe kabanzi ezinhlelweni ezidinga ukuqina okuphezulu okufana nokumbiwa uwoyela kanye nokuvikela amanzi okwakha.
8. I-Biocompatible futhi ayinabo ubuthi
I-cellulose ethers iyinhlanganisela etholakala ku-cellulose yemvelo futhi isetshenziswa kakhulu embonini yemithi nokudla ngenxa yokuhambisana kwayo okuhle nokungabi nobuthi. Njengabasizi bemithi, ama-cellulose ether angalungisa amazinga okukhululwa kwezidakamizwa futhi athuthukise ukuzinza kwezidakamizwa. Angasetshenziswa futhi njengama-thickeners, ama-stabilizers, nama-gelling agents ekwakhiweni kokudla ukuze kuqinisekiswe ukunambitheka nokuzinza komkhiqizo.
9. Ukuvikelwa kwemvelo kanye nokuzala kabusha
Ama-cellulose ethers asuselwa ku-cellulose yemvelo, okuwumthombo ovuselelekayo, futhi ukukhiqizwa kwawo nokusetshenziswa kwawo kuhambisana nemvelo. Lokhu kukwenza kube yisinqumo esifanele ukufaka esikhundleni samakhemikhali okwenziwa endabuko, ikakhulukazi namuhla ngesidingo esikhulayo sezinto ezisimeme nezihambisana nemvelo. Ukusetshenziswa kwe-cellulose ethers kuhambisana nokuthambekela kokuthuthukiswa kokuvikelwa kwemvelo kanye namakhemikhali aluhlaza.
10. Uhlu olubanzi lwezinhlelo zokusebenza
Ukuhlukahluka kwe-cellulose ethers kuholele ekusetshenzisweni okubanzi ezimbonini eziningi. Isibonelo, embonini yezokwakha, isetshenziselwa udaka lokuxuba okomile, izinamathiselo zamathayili e-ceramic, izinhlelo zangaphandle zokuvala udonga, njll.; embonini yezemithi, i-cellulose ether iyi-ejenti yokukhululwa elawulwayo evame ukusetshenziswa kanye ne-adhesive; embonini yokudla, Isetshenziswa njenge-thickener, stabilizer kanye ne-gelling agent. Ngaphezu kwalokho, i-cellulose ethers nayo idlala indima ebalulekile ezimayini zensimu kawoyela, izimonyo kanye nemikhiqizo yamakhemikhali yansuku zonke.
I-Cellulose ether iwumsebenzi we-polymer oguquguqukayo onezinzuzo eziningi njengokujiya, ukugcinwa kwamanzi, ukwakheka kwefilimu, ukuqiniswa, nokunamathela okuthuthukisiwe. Ukusetshenziswa kwayo ekwakhiweni, kwezemithi, ekudleni nakweminye imikhakha akuthuthukisi kuphela ukusebenza komkhiqizo kanye nekhwalithi, kodwa futhi kuhlangabezana nezidingo zokuvikelwa kwemvelo nentuthuko eqhubekayo. Ngokuthuthuka kobuchwepheshe kanye nokwandiswa kwezinkambu zohlelo, ama-cellulose ether azodlala indima ebaluleke kakhulu esikhathini esizayo.
