Izici ezithinta ukusebenza kwe-cellulose ether

Ukusebenza kwe-cellulose izithathekisa, njenge-hydroxypropyllylylylylyllose (HPMC), i-hpdroxyyethyl cellulose (HEC), kanye ne-carboxymethyl cellulose (CMC), kuzicelo ezahlukahlukene zithonywa yizici ezimbalwa. Ukuqonda lezi zinto kubalulekile ukwenza kahle ukusebenza kwezithambisi ze-cellulose ekwenziweni okuthile. Nazi ezinye zezinto ezibalulekile ezithinta ukusebenza kwezithambekela ze-cellulose:

1. Isakhiwo samakhemikhali: Ukwakheka kwamakhemikhali ze-cellulose izithatha, kufaka phakathi amapharamitha afana ne-degree yokufaka esikhundleni (DS), isisindo se-molecular, kanye nohlobo lwamaqembu ether (isib. Isisindo esiphakeme se-DS kanye nesisindo se-molecular ngokuvamile siholela ekugcinweni kwamanzi okuthuthukile, ukubonakala, kanye nekhono elenza ifilimu.
2. Umthamo: Inani le-cellulose ether elingezwe ekwakhekeni lidlala indima ebalulekile ekunqumeni ukusebenza kwayo. Amazinga we-decouge afanele kufanele anqunywe ngokususelwa kwizidingo ezithile zohlelo, ecabanga ngezinto ezifana nokuvunywa okufisayo, ukugcinwa kwamanzi, ukunamathela, nokusebenza nokusebenza.
3. Ubungako bezinhlayiyana kanye nokusatshalaliswa: ubukhulu bezinhlayiyana kanye nokusatshalaliswa kwe-cellulose kanye nabathobisi bathonya ukungafani kwabo nokufana ngaphakathi kokwakhiwa. Izinhlayiya ezihlakazekile ezihlakazekile ziqinisekisa i-hydration engcono nokuxhumana nezinye izinto, okuholela ekusebenzeni okuthuthukile.
4. Inqubo yokuxuba: Inqubo yokuxuba esetshenziswe ngesikhathi sokulungiswa kokwakhiwa okuqukethe izivumelwano zazo ezithinta ukusakazeka kwazo kanye ne-hydration. Amasu okuxubha okufanele aqinisekisa ukusatshalaliswa okufanayo kwe-polymer ngaphakathi kohlelo, kukhulisa ukusebenza kwawo ekunikezeni izakhiwo ezifunwayo.
5. Ukushisa kanye nomswakama: izimo zemvelo, ezinjengokushisa kanye nomswakama, zingathinta ukusebenza kwezithambisi ze-cellulose. Izinga lokushisa eliphakeme lingasheshisa ama-hydration kanye namazinga wokuchithwa, kanti amazinga okushisa aphansi anganciphisa lezo zinqubo. Amazinga omswakama angaba nomthelela nomthamo wokugcina amanzi kanye nokusebenza kwezithambekela ze-cellulose.
6. Amandla we-PH kanye ne-Ionic: Amandla we-PH kanye no-Ionic wokwakheka angathonya i-soubity kanye nokuqina kwezithambiso ze-cellulose. Zingathinta futhi ukuxhumana phakathi kwezitha ze-cellulose nezinye izinto, ezinjengesimende, ama-aggregates, kanye nezithasiselo, okuholela ezinguquko ekusebenzeni.
7. Ukuvumelana kwamakhemikhali: Abathambisi beCellulose kufanele bahambisane nezinye izakhi ezikhona ekwakhiweni, njengokwenza usimende, ama-aggregates, ama-admixture, kanye nezithasiselo. Ukungalingani noma ukusebenzisana nezinye izinto kungathinta ukusebenza kanye nezakhiwo zomkhiqizo wokugcina.
8. Izimo ze-Pring: Kuzinhlelo zokusebenza lapho kudingeka khona ukwelashwa, njengezinto zokwenziwa kokhonkolo, izimo zokwelapha (isib. Isikhathi sokulapha, izinga lokushisa, umswakama, umswakama, ukuthuthukiswa kwamandla. Ukwelashwa okufanele kuqinisekisa ukusebenza kahle kwe-cellulose afers kuMkhiqizo we-Reld.
9. Izimo Zokugcina: Izimo Zokugcina Ezifanele, kufaka phakathi izinga lokushisa, umswakama, kanye nokuchayeka ekukhanyeni, kubalulekile ukuze ulondoloze ikhwalithi kanye nokusebenza kwe-cellulose afebur. Isitoreji esingalungile singaholela ekunciphiseni, ekulahlekelweni ukusebenza kahle, kanye nezinguquko ezeza ngezakhiwo.

Ngokucabanga ngalezi zinto nokwenza kahle amapharamitha enziwe, ukusebenza kwe-cellulose afer kungathuthukiswa ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza ezimbonini ezinjengezokwakha, ezemithi, ukudla, ukunakekelwa komuntu siqu, nokuningi.
