I-Walocel kanye ne-Tylose amagama ebhrendi aziwayo ama-cellulose ether akhiqizwa abakhiqizi abahlukene, i-Dow ne-SE Tylose, ngokulandelana. Womabili ama-ethers e-Walocel kanye ne-Tylose cellulose anezinhlelo zokusebenza eziguquguqukayo ezimbonini ezihlukahlukene, ezihlanganisa ezokwakha, zokudla, ezemithi, izimonyo, nokuningi. Ngenkathi babelana ngokufana ngokususelwa ku-cellulose, banokubunjwa okuhlukile, izakhiwo, nezici. Kulesi siqhathaniso esibanzi, sizohlola umehluko nokufana phakathi kwe-Walocel ne-Tylose ngokuningiliziwe, sihlanganisa izici ezifana nezakhiwo zabo, izinhlelo zokusebenza, izinqubo zokukhiqiza, nokuningi.
Isingeniso ku-Walocel no-Tylose:
1. Walocel:
- Umkhiqizi: I-Walocel igama lomkhiqizo wama-cellulose ethers akhiqizwa yi-Dow, inkampani yamakhemikhali yamazwe ngamazwe eyaziwa ngohlu lwayo olubanzi lwemikhiqizo yamakhemikhali nezisombululo.
- Izicelo: Ama-Walocel cellulose ethers asetshenziswa ekwakheni, ekudleni, ekwelashweni kwemithi, nasezimonyoni, asebenza izindima njengama-thickeners, ama-stabilizer, ama-binder, nokunye.
- Ukucaciswa Komkhiqizo: I-Walocel inikeza izinhlobonhlobo zamabanga anezakhiwo ezihlukene, okuhlanganisa i-Walocel CRT yokwakha kanye ne-Walocel XM yezinhlelo zokudla.
- Izakhiwo Eziyinhloko: Amamaki e-Walocel angase ahluke nge-viscosity, i-degree of substitution (DS), kanye nosayizi wezinhlayiyana, awenze afanelekele izinhlelo zokusebenza ezihlukahlukene. Baziwa ngokugcina amanzi, amandla okuqina, kanye nezakhiwo zokwenza ifilimu.
- Ubukhona Bomhlaba Wonke: I-Walocel iwuphawu olwaziwayo olutholakala emhlabeni wonke futhi lutholakala ezifundeni eziningi.
2. I-Tylose:
- Umkhiqizi: I-Tylose igama lomkhiqizo wama-cellulose ethers akhiqizwa u-SE Tylose, inkampani ephethwe yi-Shin-Etsu Chemical Co., Ltd. I-Shin-Etsu iyinkampani yamakhemikhali yomhlaba wonke enephothifoliyo yemikhiqizo ehlukahlukene.
- Izicelo: Ama-ether e-Tylose cellulose anezinhlelo zokusebenza zokwakha, ukudla, imithi, izimonyo, nokuningi. Zisetshenziswa njengama-thickeners, stabilizers, binders, kanye nabaqambi bamafilimu.
- Ukucaciswa Komkhiqizo: I-Tylose inikeza uhla lwemikhiqizo ye-cellulose ether eklanyelwe izinhlelo zokusebenza ezithile. Amabanga afana ne-Tylose H ne-Tylose MH avame ukusetshenziselwa ukwakha kanye nemithi.
- Izakhiwo Eziyinhloko: Amamaki e-Tylose abonisa ukuhluka kwe-viscosity, i-degree of substitution (DS), nosayizi wezinhlayiyana, kuye ngebanga elithile kanye nesicelo. Baziwa ngokugcina amanzi, amandla okuqina, nokulawula i-rheological.
- Ubukhona Bomhlaba Wonke: I-Tylose iwuphawu olwaziwayo olutholakala emhlabeni wonke, olutholakala ezifundeni eziningi.
Ukuqhathaniswa kukaWalocel noTylose:
Ukuze siqonde umehluko phakathi kwe-Walocel ne-Tylose, sizohlola izici ezihlukahlukene zale mikhiqizo ye-cellulose ether, okuhlanganisa izakhiwo, izinhlelo zokusebenza, izinqubo zokukhiqiza, nokuningi:
1. Izakhiwo:
Walocel:
- Amabanga e-Walocel angase ahluke nge-viscosity, degree of substitution (DS), usayizi wezinhlayiyana, nezinye izakhiwo, eziklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zohlelo lokusebenza.
- I-Walocel yaziwa ngokugcina amanzi, amandla okuqina, kanye nezakhiwo zokwenza ifilimu ekwakhiweni okuhlukahlukene.
I-Tylose:
- Amamaki e-Tylose aphinde abonise umehluko wezakhiwo, kufaka phakathi i-viscosity, i-DS, nosayizi wezinhlayiyana, kuye ngebanga elithile kanye nokusebenza. Zenzelwe ukunikeza ukulawula kwe-rheological nokugcinwa kwamanzi ekubunjweni.
2. Izinhlelo zokusebenza:
Kokubili i-Walocel ne-Tylose isetshenziswa kulezi zimboni nezinhlelo zokusebenza ezilandelayo:
- Ukwakhiwa: Asetshenziswa ezintweni zokwakha, njengezinamathelisi zamathayili, ama-mortars, ama-grouts, nama-self-leveling compounds, ukuthuthukisa izakhiwo ezifana nokugcinwa kwamanzi, ukusebenza, nokunamathela.
– Ezemithi: Embonini yezemithi, zombili zisebenza njengezibopheli, ezihlukanisayo, nama-ejenti akhishwayo okulawulwayo ekwakhiweni kwesistimu yokulethwa kwezidakamizwa.
- Ukudla: Kusetshenziswa embonini yokudla ukuze kushube, kuzinziswe, futhi kuthuthukiswe ukuthungwa kwemikhiqizo yokudla, njengamasoso, okokugqoka, nezinto ezibhakwayo.
- Izimonyo: Kokubili i-Walocel ne-Tylose isetshenziswa kuzimonyo nemikhiqizo yokunakekelwa komuntu siqu ukunikeza i-viscosity, ukuthungwa, kanye nokuqiniswa kwe-emulsion.
3. Izinqubo Zokukhiqiza:
Izinqubo zokukhiqiza ze-Walocel ne-Tylose zibandakanya izigaba ezifanayo, njengoba zombili zingama-cellulose ether. Izinyathelo ezibalulekile ekukhiqizeni kwazo zihlanganisa:
- Ukwelashwa Nge-alkaline: Umthombo we-cellulose uphathwa nge-alkaline ukuze kukhishwe ukungcola, kuvuvuke imicu ye-cellulose, futhi kwenziwe kufinyeleleke kuyo ukuze kulungiswe okunye amakhemikhali.
- I-Etherification: Phakathi nalesi sigaba, amaketanga e-cellulose aguqulwa amakhemikhali ngokwethula i-hydroxypropyl kanye namaqembu e-methyl. Lezi zinguquko zinesibopho sokuncibilika kwamanzi nezinye izakhiwo.
- Ukugeza nokungathathi hlangothi: Umkhiqizo uyawashwa ukuze kukhishwe amakhemikhali nokungcola okungaphenduliwe. Ibe isincishiswa ukuze kuzuzwe izinga le-pH elifunekayo.
- Ukuhlanzwa: Izinqubo zokuhlanza, okuhlanganisa ukucwenga nokugeza, zisetshenziselwa ukususa noma yikuphi ukungcola okusele kanye nemikhiqizo esele.
- Ukomisa: I-purified cellulose ether yomiswa ukuze kuncishiswe umswakama wayo, okuyenza ifanelekele ukusetshenzwa okwengeziwe nokupakishwa.
- I-Granulation kanye Nokupakishwa: Kwezinye izimo, i-ether ye-cellulose eyomisiwe ingase ithole i-granulation ukuze kuzuzwe usayizi wezinhlayiyana ezifunekayo nezici zokugeleza. Umkhiqizo wokugcina ube usupakishwa ukuze usakazwe.
4. Ukutholakala Kwesifunda:
Kokubili i-Walocel ne-Tylose zinobukhona bomhlaba wonke, kodwa ukutholakala kwamabanga athile nokwakheka kungase kuhluke ngesifunda. Abahlinzeki bendawo nabasabalalisi bangase banikeze izinketho ezahlukene zomkhiqizo ngokusekelwe esidingweni sesifunda.
5. Amagama Amabanga:
Kokubili i-Walocel ne-Tylose zinikeza amagama ebanga ahlukahlukene, ngalinye lakhelwe izinhlelo zokusebenza ezithile noma izici. Lawa mabanga akhethwe ngezinombolo nezinhlamvu ezikhombisa izakhiwo zawo kanye nokusetshenziswa okunconyiwe.
Kafushane, i-Walocel ne-Tylose yimikhiqizo ye-cellulose ether eyabelana ngezinhlelo zokusebenza ezivamile ekwakhiweni, ekudleni, ekwemithi, nasezimonyo. Umehluko oyinhloko phakathi kwawo usemkhiqizweni, ukwakheka komkhiqizo othile, kanye nokutholakala kwesifunda. Yomibili le mikhiqizo inikezela ngebanga lamabanga enzelwe izinhlelo zokusebenza ezahlukene, ngalinye linokwehluka kwezakhiwo. Lapho ukhetha phakathi kwe-Walocel ne-Tylose ngohlelo lokusebenza oluthile, kubalulekile ukuthintana nabakhiqizi abafanele noma abahlinzeki ukuze unqume umkhiqizo ofaneleka kakhulu futhi ufinyelele ulwazi lomkhiqizo lwakamuva nosekelo lobuchwepheshe.
