I-Methocel ne-Culminal yimikhiqizo emibili ehlukene ye-cellulose ether ekhiqizwa ngokuhlukileAbakhiqizi be-cellulose ether, i-Dow Chemical ne-Ashland, ngokulandelana.Lezi zinto eziphuma ku-cellulose zabelana ngezinhlelo zokusebenza ezivamile ezimbonini ezihlukahlukene, ezihlanganisa ezokwakha, ezemithi, ukudla, nezimonyo.Kodwa-ke, abonisa umehluko ngokuya komkhiqizi, ukwakheka, izakhiwo ezithile, nezici zokusebenza.Kulesi siqhathaniso esibanzi, sizohlola umehluko nokufana phakathi kwe-Methocel ne-Culminal ngokuningiliziwe, sihlanganisa izakhiwo zayo, izinhlelo zokusebenza, izinqubo zokukhiqiza, nokuningi.
Isingeniso seMethocel neCulminal:
1. I-Methocel:
- Umkhiqizi: I-Methocel yigama lomkhiqizo wama-cellulose ethers akhiqizwa yi-Dow Chemical, inkampani yamakhemikhali yamazwe ngamazwe enezinhlobonhlobo ezihlukahlukene zamakhemikhali kanye nemikhiqizo ye-polymer.
- Izicelo: I-Methocel cellulose ethers isetshenziswa ekwakheni, emithini yemithi, ekudleni nasezimonyo.Zisebenza njengama-thickeners, ama-binders, ama-stabilizer, nokunye.
- Ukucaciswa Komkhiqizo: I-Methocel inikeza amamaki anhlobonhlobo anezakhiwo nezindlela zokusebenza ezahlukene, okuhlanganisa i-Methocel CRT yokwakha kanye ne-Methocel MW yezemithi.
- Izakhiwo Ezibalulekile: Amabanga e-Methocel angabonisa umehluko ku-viscosity, izinga lokushintshwa (DS), nezinye izakhiwo.Baziwa ngokugcina amanzi, amandla okuqina, kanye nezakhiwo zokwenza ifilimu.
- I-Global Presence: I-Methocel wuphawu lwe-cellulose ether olwaziwayo olutholakala emhlabeni wonke, olutholakala ezifundeni ezihlukahlukene.
2. Isiphetho:
- Umkhiqizi: I-Culminal igama lomkhiqizo wama-cellulose ethers akhiqizwa yi-Ashland, inkampani yamakhemikhali ekhethekile yamazwe ngamazwe.I-Ashland igxile ezinhlobonhlobo zezixazululo zamakhemikhali nemikhiqizo.
- Izicelo: Ama-Culminal cellulose ethers asetshenziswa ekwakheni, emithini yemithi, ekudleni, nasezintweni zokugcoba, ezifana ne-Methocel.Basebenza izindima njengama-thickeners, ama-binders, ama-stabilizer, nokunye.
- Imininingwane Yomkhiqizo: I-Culminal inikeza uhla lwemikhiqizo ye-cellulose ether eklanyelwe izinhlelo zokusebenza ezithile.Amabanga afana ne-Culminal C kanye ne-Culminal M avame ukusetshenziswa ekwakhiweni nasekwenzeni imithi, ngokulandelana.
- Izakhiwo Ezibalulekile: Amabanga aphakeme abonisa ukuhluka kwe-viscosity, usayizi wezinhlayiyana, kanye ne-DS, kuye ngohlelo oluhlosiwe.Baziwa ngokugcina amanzi, amandla okuqina, nokulawula i-rheological.
- I-Global Presence: I-Culminal wumkhiqizo owaziwayo onokutholakala emhlabeni wonke, otholakala ezifundeni ezihlukahlukene.
Ukuqhathaniswa kweMethocel neCulminal:
Ukuze siqonde umehluko phakathi kwe-Methocel ne-Culminal, sizohlola izici ezihlukahlukene zale mikhiqizo ye-cellulose ether, okuhlanganisa izakhiwo, izinhlelo zokusebenza, izinqubo zokukhiqiza, nokuningi:
1. Izakhiwo:
I-Methocel:
- Amabanga e-Methocel angahluka nge-viscosity, degree of substitution (DS), usayizi wezinhlayiyana, nezinye izakhiwo.Lokhu kuhlukahluka kuyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene.
- I-Methocel yaziwa ngokugcina amanzi, amandla okuqina, ukuthuthukiswa kokunamathela, kanye nezakhiwo zokwenza ifilimu.
I-culminal:
- Amamaki e-Cultural nawo akhombisa umehluko wezakhiwo, okubandakanya i-viscosity, i-DS, nosayizi wezinhlayiyana, kuye ngebanga elithile kanye nokusebenza.
- I-Culminal cellulose ethers ibonwa ngokugcina amanzi, amandla okuqina, nokulawula i-rheological ekwenziweni okuhlukahlukene.
2. Izinhlelo zokusebenza:
Kokubili iMethocel neCulminal isetshenziswa kulezi zimboni nasezintweni ezilandelayo:
- Ukwakhiwa: Bathola ukusetshenziswa ezintweni zokwakha, njengezinamathelisi zamathayili, ama-mortars, ama-grouts, nezinhlanganisela ezizilinganisa, ukuze kuthuthukiswe izakhiwo ezifana nokugcinwa kwamanzi, ukusebenza kahle, nokunamathela.
- Ezemithi: Embonini yezemithi, bobabili baqashwa njengabahlanganisayo, abahlukanisayo, nabakhipha okulawulwayo ekwenziweni kwethebhulethi kanye nesistimu yokulethwa kwezidakamizwa.
- Ukudla: Kusetshenziswa embonini yokudla ukuze kushube, kuzinzise, futhi kuthuthukiswe ukuthungwa kwemikhiqizo yokudla, njengamasoso, okokugqoka, nezimpahla zokubhaka.
- Izimonyo: Kokubili i-Methocel kanye ne-Culminal isetshenziswa kuzimonyo nemikhiqizo yokunakekelwa komuntu siqu ukunikeza i-viscosity, ukuthungwa, kanye nokuqiniswa kwe-emulsion.
3. Izinqubo Zokukhiqiza:
Izinqubo zokukhiqiza ze-Methocel ne-Culminal zibandakanya izinyathelo ezifanayo, njengoba zombili zingama-cellulose ether.Izigaba ezibalulekile zifaka:
- 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-Methocel kanye ne-Culminal zinobukhona bomhlaba wonke, kodwa ukutholakala kwamabanga athile nokwakheka kungase kuhluke ngokwesifunda.Abahlinzeki bendawo nabasabalalisi bangase banikeze izinketho ezahlukene zomkhiqizo ngokusekelwe esidingweni sesifunda.
5. Amagama Amabanga:
Kokubili i-Methocel kanye ne-Culminal zinikeza amagama ebanga ahlukahlukene, ngalinye lakhelwe izinhlelo zokusebenza ezithile noma izici ezithile.Lawa mabanga akhethwe ngezinombolo nezinhlamvu ezikhombisa izakhiwo zawo kanye nokusetshenziswa okunconyiwe.
Ngokufigqiwe,I-Methocelkanye ne-Culminal imikhiqizo ye-cellulose ether ehlanganyela izinhlelo ezivamile zokwakha, imithi, ukudla, nezimonyo.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-Methocel ne-Culminal ukuze uthole isicelo esithile, kubalulekile ukubonisana nabakhiqizi abafanele noma abahlinzeki bempahla ukuze uthole umkhiqizo ofaneleka kakhulu futhi ufinyelele ulwazi lomkhiqizo lwakamuva kanye nokwesekwa kobuchwepheshe.
