I-Consult-gradence cellulose i-Tesher (cellulose ether) ama-polymer ahlanganisiwe atholakala ngokushintshana kokuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Zisetshenziswa kabanzi ezintweni ezifana nodaka, ukumboza, kanye nezinamathela embonini yezokwakha. I-Cellulose Afers ingahlukaniswa ngezinhlobo eziningana ngokuya ngesakhiwo se-molefanelar nezakhiwo. Izinhlobo ezijwayelekile zifakaI-methyl cellulose ether (MC),I-Hydroxyethyl cellulose ether (HEC),I-Hydroxypropyl methylcellulose (HPMC)nezinto zazo ezivela emvelweni. Lawa ma-cellulose afers anezinto ezahlukene zenyama nangamakhemikhali futhi alungele izinto ezahlukene zokwakha kanye nezidingo zenqubo.
1. I-methyl cellulose ether (MC)
I-Methyl Cellulose Ether yi-ether ye-cellulose yakuqala yakudala futhi enye yezithambiso ezasetshenziswa kakhulu ze-cellulose zokwakha. Izici zalo eziphambili zifaka:
I-Solubity:I-MC ingakha isixazululo se-colloidal esibonakalayo emanzini abandayo.
Ukuqina:Odongeni lwezokwakha, i-MC ingakhulisa kakhulu ukubonwa kwesixazululo futhi ithuthukise ukuvumelana kodaka.
Ukugcinwa kwamanzi:I-MC inokugcinwa kwamanzi okuhle futhi ingavimba ngempumelelo udaka ukuthi avele avele ngokushesha ngesikhathi sokwakha, ngaleyo ndlela aqinisekise ukusebenza kokwakha kanye namandla alandelayo.
Ukusebenza Kwezokwakha:Kungathuthukisa ukusebenza kodaka futhi kunwebe isikhathi esivulekile, okwenza kube lula ukusebenza ngesikhathi sokwakha.
2. I-Hydroxyyethyl cellulose ether (HEC)
I-Hydroxyyethyl cellulose ether yi-cellulose ether enamaqembu we-hydroxyethyl angeniswa ku-molecule ye-cellulose. Izici zalo eziphambili zifaka:
I-Solubity:I-HEC ingancibilikisa ngokushesha emanzini ukwakha ikhambi elisobala le-viscous.
Ukuqina:Uma kuqhathaniswa ne-MC, i-HEC inomphumela wokuqina onamandla futhi ivame ukusetshenziswa ezintweni zokwakha ezidinga i-Rhelogy ephezulu nokuvunywa.
Ukugcinwa kwamanzi:I-HEC inokugcinwa kahle kwamanzi futhi ingagcina umsinga wesikhathi eside ukuvikela udaka ekusomisweni nasekuqhekekeni.
I-Anti-ukumiswa:I-HEC ingathuthukisa amandla okumiswa kwezinhlayiya eziqinile ku-slurry ukugwema ukudilizwa noma ukuxhumeka kwezinhlayiyana.
Anti-free:I-HEC inokuguquguquka okuhle kwamazinga okushisa aphansi futhi ingasetshenziswa ezindaweni ezibandayo.
3. I-Hydroxypropyl methylcellulose (HPMC)
IHydroxypropyl Methylcellulose iyi-cellulose ether etholwe esikhundleni se-hydroxyl gerow ku-molecule ye-cellulose nge-hydroxyproppy group. Izici zalo eziphambili zifaka:
I-Solubity:I-HPMC ingancibilikisa ngokushesha emanzini ukuze kwakhiwe i-colloid esobala enokubonakala okuphezulu.
Ukuqina nokuqina:I-HPMC inomphumela oqinile wokuqina. Ngenkathi ukhulisa ukubonakala kokwakha, kungagcina ukuqina kodaka nokunciphisa ukuhanjiswa kwensizwa.
Ukumelana nokushisa okuphezulu:Uma kuqhathaniswa ne-MC ne-HEC, i-HPMC inokubekezelela okunamandla kumazinga okushisa aphezulu, ngakho-ke kufanelekile ukwakhiwa kwezinye izindawo eziphakeme zokushisa.
Ukumelana ne-Hydrolysis:I-HPMC inokuqina okuhle kwe-hydrolysis futhi ilungele ukusetshenziswa ezindaweni ezinomswakama.
I-4. Izakhiwo ezibanzi ze-cellulose afers
Ukusetshenziswa kwe-cellulose Tashers embonini yezokwakha ikakhulukazi kuncike kwizakhiwo zayo ezahlukahlukene, ikakhulukazi emikhiqizweni efana nodaka, izimbotshana, kanye nezinamathela. Lokhu okulandelayo kuyizakhiwo eziningana ezikhona ezikhona ze-cellulose afer:
Ukuqina:I-Cellulose Tashers ithuthukisa kakhulu ukusebenza kokwakha kwezimbozo noma zodaka ngokwandisa ubuhlakani be-liquid, futhi ine-fluodity ne-decticity enhle.
Ukugcinwa kwamanzi:Usimende kasimende nakwezinye izinto zokwakha, ukugcinwa kwamanzi kwezimali ze-cellulose kusiza ukuvikela amanzi ekuthobeni ngokushesha okukhulu, aqinisekise ukunamathela ngesikhathi sokwakha, futhi andise isikhathi sokusebenza.
Ukumelana nokuqhekeka:I-Celsulose Ether ingathuthukisa ngempumelelo ukumelana nokuqhekeka kwezinto zokwakha futhi inciphise imifantu ebangelwa ukomisa i-shrinkage noma amabutho angaphandle.
Ukusebenza:Ukusetshenziswa kwe-cellulose ether kungathuthukisa ukukhiqizwa kwezinto zokwakha futhi kuthuthukise ukusebenza kahle kwabasebenzi.
I-Anti-Sedimentation:Ikakhulu ekwakhiweni okumanzi, i-cellulose ether inganciphisa ukunqunyelwa kwezakhi eziqinile futhi ilondoloze ukuvumelana kwe-slurry.
5. Izinkambu zohlelo lokusebenza
I-Ether yokwakha I-Cellulose ether isetshenziswa ikakhulukazi ezinhlotsheni ezilandelayo zezinto zokwakha:
Udaka:I-Celsulose Ether ingathuthukisa ukuwenza, ukugcinwa kwamanzi, ukumelana kwamanzi kanye nokulwa nokulwa nokulwa nodaka, futhi kusetshenziswa kabanzi ngodaka olubopha ngodaka, udaka ngodaka, ukulungisa udaka, njll.
Penda:I-Cellulose Ether ingasetshenziswa njengomkhulu kanye ne-distrants ngopende ukuze kuthuthukiswe uketshezi nokunamathela kopende.
Adhesive:Ukungeza i-cellulose ether kwifomula yokunamathela kusiza ukukhulisa i-viscosive yokunamathela futhi uthuthukise ukusebenza kokwakha.
Udaka oluxubile oluhlanganisiwe:Isetshenziswa ngodaka oluhlanganisiwe olomile, ihlinzeka ngokulondolozwa okuthile nokugcinwa kwamanzi ukuze iqinisekise ukuthi akulula ukucwilisa emzimbeni ngesikhathi sokwakha.
I-Ether yokwakha I-Cellulose ether inamathemba okusebenza abanzi embonini yezokwakha ngenxa yokuqina kwayo okuhle, ukugcinwa kwamanzi, ukumelana nokuqhekeka nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo nezinye izakhiwo. Izinhlobo ezahlukahlukene zeI-Cellulose Afers(njenge-MC, i-HEC, i-HPMC) inezimpawu ezahlukahlukene kanye namabanga okusebenzisa. Ukukhetha i-ether ye-cellulose efanele kungafinyelela ukusebenza okuhle nemiphumela ezintweni zokwakha. Ngokuthuthukiswa kobuchwepheshe bokwakha kanye nezinguquko ekufuneni, izinkambu ezahlukahlukene kanye nezicelo ze-cellulose ether nazo zikhula njalo, futhi izinhlobo ezintsha ze-cellulose kanye nezithako zazo zingavela esikhathini esizayo.
