Umbuzo osheshayo mayelana ne-cellulose afers

01. Ukusetshenziswa okuyinhloko kwe-cellulose ether hpmc?

I-HPMC isetshenziswa kabanzi ku-zokwakha udaka, upende osuselwa emanzini, i-sonthetic resin, ceramics, umuthi, ukudla, izindwangu, izimonyo, ugwayi, kanye nezinye izimboni. Ihlukaniswe ebangeni lokwakha, ibanga lokudla, ibanga lemithi, ibanga lezimboni le-PVC kanye nebanga lansuku zonke lamakhemikhali.

02. Zithini ukuhlukaniswa kwe-cellulose?

Amaselula ajwayelekile yi-MC, HPMC, Mhec, CMC, Hec, EC
Phakathi kwazo, i-HEC ne-CMC zisetshenziswa kakhulu egqoke izigqoko ezisuselwa emanzini,
I-CMC ingabuye isetshenziswe kuma-ceramics, inkambu kawoyela, ukudla kanye nezinye izinkambu
I-EC isetshenziswa kakhulu kwezokwelapha, ukunamathisela kwesiliva kagesi namanye amasimu
I-HPMC ihlukaniswe imininingwane ehlukahlukene ngodaka, umuthi, ukudla, imboni ye-PVC, imikhiqizo yamakhemikhali nsuku zonke nezinye izimboni

03. Uyini umehluko phakathi kwe-HPMC ne-MHHEC isicelo?

Izakhiwo zezinhlobo ezimbili zeselula ngokufanayo, kepha ukuqina okuphezulu kwe-Mhec kungcono, ikakhulukazi ehlobo lapho izinga lokushisa lodonga liphezulu, futhi ukusebenza kokugcinwa kwamanzi kwe-MHCC kungcono kunalokho kwe-HPMC ngaphansi kwezimo zokushisa eziphakeme.

04. Ungahlulela kanjani ikhwalithi ye-HPMC?

1) Yize ubumsulwa bungakwazi ukuthola ukuthi i-HPMC kulula ukuyisebenzisa, futhi uma ngabe ama-anchents amhlophe angezwe kwinqubo yokukhiqiza, ikhwalithi izothinteka, kepha iningi lemikhiqizo emihle linokwahlulelwa kahle ngokubukeka.
2) Ukuhamba okukhanyayo: Ngemuva kokuncibilikisa i-HPMC emanzini ukuze wakhe i-colloid esobala, bheka ukudluliselwa kwalo okukhanyayo. Ukwenza ngcono ukudluliselwa kokukhanya, udaba oluncane olungaphansi kwalokho, futhi ikhwalithi yinhle.
Uma ufuna ukwahlulela kahle ikhwalithi ye-cellulose, indlela ethembeke kakhulu ukusebenzisa imishini yobungcweti kwilebhu yochwepheshe yokuhlola. Izinkomba zokuhlola eziphambili zifaka i-viscosity, isilinganiso sokugcina amanzi, nokuqukethwe komlotha.

05. Ukukala ukubonakala kwe-cellulose?

I-Viscometer ejwayelekile emakethe yaseCellulose Famermat yi-NDJ, kepha emakethe yamazwe omhlaba, abakhiqizi abahlukene bavame ukusebenzisa izindlela zokuhlola ze-viscosity ezahlukahlukene. Okujwayelekile yi-Brookfeild RV, i-hoppler, futhi kukhona nezisombululo ezihlukile zokutholwa, ezihlukaniswe ngesisombululo esingu-1% kanye nesixazululo esingu-2%. Ama-viviscoeter ahlukene nezindlela ezihlukile zokutholwa zivame ukubangela umehluko wezikhathi eziningana noma izikhathi eziningi ku-viscosity imiphumela.

06. Uyini umehluko phakathi kohlobo lwe-HPMP

Imikhiqizo esheshayo ye-HPMC ibhekisela kwimikhiqizo ehlakazeka ngokushesha emanzini abandayo, kepha kufanele kuphawulwe ukuthi ukusakazeka akusho ukuchithwa. Imikhiqizo esheshayo ibhekwa nge-GLLOXAL ebusweni futhi bahlakazeka emanzini abandayo, kepha abaqali ukuncibilikisa ngokushesha. , ngakho-ke i-viscosity ayikhiqizwa ngokushesha ngemuva kokuhlakazeka. Lapho likhulu inani lentengo ye-Gyoxal Surface, ngokushesha ukuhlakazeka, kepha ukushesha okubonakalayo, okuncane inani le-glyoxoxo, kanye okuphambene nalokho.

07. I-Compound Cellulose kanye ne-Cellulose eguquliwe
Manje kunamaselula amaningi aguqulwe futhi ahlanganise iselula emakethe, ngakho-ke yini ukuguqulwa kanye nokuhlanganiswa?

Lolu hlobo lwe-cellulose luvame ukuba nezakhiwo ezingenazo noma zikhulise ezinye zezakhiwo zalo, njenge: I-anti-splip, ithuthukise isikhathi esivulekile, ikhuphukile isikhathi esivulekile futhi isebenzisa i-cellulose eshibhile futhi isebenzisa i-cellulose eshibhile noma i-cellulose elungisiwe
