IHydroxYethyl Methylcellulose (Hemc) iyi-ether ye-annoinic cellulose, okuwumkhiqizo oguquliwe otholwe yi-hydroxyethyylating methylcellulose (MC). I-Hemc inezinto eziningi ezihlukile zenyama nangamakhemikhali, ezenza zisetshenziswe kabanzi ekwakheni, umuthi, ukudla kanye nezinye izinkambu.
1. I-solubity kanye ne-solubility
I-Hemc ine-soubity enhle emanzini. Ingancibilika ngokushesha emanzini abandayo ukwakha isixazululo esisobala noma esibonakalayo, futhi ngaphakathi kwebanga elithile lokuhlushwa, ikhambi laso libonisa izakhiwo ezi-viscous. Isixazululo esinamanzi se-hemc sine-pseudoplazity, okungukuthi, njengoba izinga le-shear likhuphuka, ukubonakala kwesisombululo kuyancipha. Le mpahla yenza kube kuhle kakhulu kuzicelo ezifana nezembatho zokwakha kanye nama-adhesives.
2. Ukuqina
I-Hemc inezakhiwo ezinhle kakhulu zokuqina futhi ingakhulisa ngempumelelo ukubonwa kwezinhlelo ezenzelwe amanzi. Umphumela wayo wokuqina awuhlobene kuphela nesisindo se-molecular, kodwa futhi nasezicini ezifana nokuhlushwa, i-PH VALUE NOLUSE. IHemc isetshenziswa kabanzi ezintweni zokwakha ezifana nezinto zodaka zodaka kanye nezinto zokwakha ama-gypsum ngenxa yomthelela wayo omnene wokuqina kanye nokuthambekela kwalo okuphansi kokudala ukubheja kwalolu hlelo.
3. Ukugcinwa kwamanzi
I-Hemc inezakhiwo ezinhle zokugcina amanzi, okwenza kube yisengezo esibalulekile ezintweni zokwakha. Ingagcina umswakama ezintweni ezisetshenziswayo kasimende, yandisa isikhathi sayo esivulekile, futhi ithuthukise ukusebenza kanye nezakhiwo zokwakha zezinto zokwakha. Ngaphezu kwalokho, izakhiwo zokugcina amanzi ze-hemc nazo zikwenza kusetshenziswe kabanzi ekuhlotsheni, ezinamathelayo kanye nezimboni zokudla, ezingavimba amanzi ohlelweni ngokushesha okukhulu.
4. Izakhiwo ezenziwe ngefilimu
I-Hemc ingakha ifilimu efanayo ebusweni ngezakhiwo ezinhle ezenziwe ngamafilimu. Le filimu inamandla athile nokuqina, futhi ingasetshenziselwa ukuvikela ukunamathela futhi ivikele ukungena kwamanzi. Izakhiwo ezenziwe ngefilimu zizenza ukuthi zibe nezicelo ezibalulekile ku-Coatings, Paints, Agents Coation kanye nezinye izinkambu.
5. Ukuqina
I-Hemc inezakhiwo ezizinzile zamakhemikhali kanye nokubekezelelana okuhle kwezindawo ezi-acid ne-alkali. Isixazululo saso samanzi sihlala sizinzile ngobubanzi be-PH (imvamisa 2-12) futhi abuthambekele ekutholeni noma kwezulu. Ngaphezu kwalokho, i-hemc nayo inokuqina okuthile kokukhanya, ukushisa kanye ne-oxidation, ukuze kusasebenza ngaphansi kwezimo ezinzima.
6 I-BioComSthishon nokuphepha
I-HEMC iyikhompiyutha engeyona eye-ionic evame ukungabangeli i-allergies noma okunye ukusabela okuhlukile futhi ine-biocomps enhle. Ngakho-ke, emikhakheni yezokwelapha nokudla, i-hemc ivame ukusetshenziswa njengomuntu omkhulu, i-stabilizer kanye ne-capsule impahla. Ukuphepha kwayo kwenza ukuthi isetshenziswe kabanzi ekunakekelweni kwesikhumba kanye nemikhiqizo yokunakekelwa komuntu siqu.
7. Ukumelana nosawoti
Uma kuqhathaniswa nezinye izinhlobo ze-cellulose afers, i-hemc inokubekezelela okungcono kuma-electrolyte. Kusengakugcina ukubonakala okuhle nokuqina ezinhlelweni eziqukethe ukugxila okuphezulu kosawoti. Lesi sici sinikeza izinzuzo kwezinye izinhlelo ezikhethekile, njengokungezelelwa kwe-fluid fluid ekuxhashazweni kwensimu yamafutha.
8. Ukugcona nokumiswa
Izisombululo zeHemc zinokuthambisa nokumiswa okuhle, okungathuthukisa uxhaso kanye nokufana kokwakha. Lokhu kubaluleke kakhulu ezintweni ezisetshenziswayo kasimende, ezingathuthukisa ukusebenza kanye nezindawo ezilwa nokuvimbela impahla.
I-Hydroxyswethyl methylcellulose isetshenziswa kabanzi ezintweni zokwakha, umuthi, ukudla, izimonyo kanye nezinye izinkambu ngenxa yokuqina kwayo okuhle, ukugcinwa kwamanzi, ukwakha amafilimu nokuqina. Izakhiwo zalo ezingezona eze-ionic, ukufana okuhle nokuqina kwenza kube yisengezo esisebenzayo esingadlala indima ebalulekile ezinhlobonhlobo zezicelo zezimboni.
