Yiziphi ukusetshenziswa kwe-cellulose ethers?

I-cellulose ethers iyisigaba esibalulekile sokuphuma kwe-polymer yemvelo, esetshenziswa kakhulu emikhakheni eminingi yezimboni neyokuphila. Ama-cellulose ethers ayimikhiqizo ye-cellulose eguquliwe eyakhiwe ngokuhlanganisa i-cellulose yemvelo nezinhlanganisela ze-ether ngokusabela kwamakhemikhali. Ngokusho kwama-substitutes ahlukene, ama-cellulose ether angahlukaniswa abe yi-methyl cellulose (MC), i-hydroxypropyl methyl cellulose (HPMC), i-carboxymethyl cellulose (CMC) nezinye izinhlobo. Le mikhiqizo inokuqina okuhle, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi, ukugcotshwa nezinye izakhiwo, ngakho-ke isetshenziswa kabanzi ekwakheni, emithini, ekudleni, kwezimonyo, ekukhishweni kukawoyela, ukwenza amaphepha nezinye izimboni.

1. Imboni yezokwakha

I-cellulose ethers idlala indima ebalulekile ezintweni zokwakha, ikakhulukazi odakeni olomile, i-putty powder, i-coatings kanye ne-adhesives yama-tile. Imisebenzi yayo eyinhloko ihlanganisa ukuqina, ukugcinwa kwamanzi, ukugcotshwa kanye nokusebenza okuthuthukisiwe kokwakhiwa. Ngokwesibonelo:

Umthelela wokujiya: Ama-cellulose ether angakhuphula i-viscosity yodaka nama-coatings, awenze abe ngcono ekwakhiweni futhi agweme ukuwohloka.

Ukugcinwa kwamanzi: Endaweni eyomile, i-cellulose ether ingagcina umswakama ngempumelelo, ivimbele amanzi ukuthi angahwamuki ngokushesha, iqinisekise ukugeleza okugcwele kwezinto zikasimende ezifana usimende noma igypsum, futhi ithuthukise amandla okubopha kanye nokusebenza kwempahla.

Thuthukisa ukusebenza komsebenzi wokwakha: I-Cellulose ether ingathuthukisa ukuthambisa kwezinto zokwakha, izenze zibe bushelelezi ngesikhathi sokwakha, zibe lula ukuzisebenzisa noma ukubeka, futhi zithuthukise ukusebenza kahle kokwakhiwa kanye nekhwalithi yendawo.

2. Imboni yezemithi

Emkhakheni wezokwelapha, i-cellulose ether isetshenziswa kakhulu ekulungiseni izidakamizwa, embozweni yamathebulethi, nakubathwali bezidakamizwa ezikhishwa isikhathi eside. Ukusetshenziswa okuvamile kufaka:

Ukubumba ithebhulethi: I-Cellulose ether, njenge-binder ne-disintegrant yamaphilisi, ingakhuthaza ngempumelelo ukwakheka kwamaphilisi futhi ihlakazeke ngokushesha lapho ithathwa ukuze kuqinisekiswe ukumuncwa kwezidakamizwa.

Isistimu yokukhululwa elawulwayo: Amanye ama-cellulose ether anezakhiwo ezinhle zokwakha ifilimu kanye nezakhiwo zokuwohloka okulawulekayo, ngakho-ke avame ukusetshenziswa ekulungiseleleni izidakamizwa ezikhishwa isikhathi eside, ezingalawula izinga lokukhishwa kwezidakamizwa emzimbeni womuntu futhi andise ukusebenza kwezidakamizwa isikhathi eside.

I-Capsule coating: Indawo eyenza ifilimu ye-cellulose ether iyenza ibe into ekahle yokuhlanganisa izidakamizwa, engahlukanisa izidakamizwa endaweni yangaphandle, igweme ukukhishwa kwe-oxidation kanye ne-hydrolysis yezidakamizwa, futhi ikhulise ukuzinza kwezidakamizwa.

3. Imboni yokudla

Embonini yokudla, ama-cellulose ethers asetshenziswa kabanzi njengezithasiselo, ikakhulukazi ezimpahleni ezibhakwayo, emikhiqizweni yobisi, eziphuzweni nasezindaweni eziqandisiwe. Imisebenzi yayo eyinhloko ihlanganisa:

I-Thickener: Ama-cellulose ether angakhuphula i-viscosity yokudla okuwuketshezi, athuthukise ukunambitheka, futhi enze imikhiqizo ibe nesakhiwo futhi eminyene. Avame ukusetshenziswa ekudleni okufana nososo, ojeli, nokhilimu.

I-Stabilizer: I-Cellulose ethers, njengama-emulsifiers kanye ne-stabilizers, ingavimbela ngokuphumelelayo ukuhlukaniswa kwamafutha namanzi ekudleni futhi iqinisekise ukuhambisana nekhwalithi yemikhiqizo.

I-Humectant: Ekudleni okubhakiwe, i-cellulose ethers ingasiza inhlama igcine umswakama, ivimbele ukulahlekelwa kwamanzi amaningi ngesikhathi sokubhaka, futhi iqinisekise ukuthambile nokunambitha komkhiqizo ophelile.

4. Imboni yezimonyo

Ukusetshenziswa kwama-cellulose ethers embonini yezimonyo kubonakala kakhulu emikhiqizweni yokunakekelwa kwesikhumba, ama-shampoos, izinto zokuhlanza ubuso kanye nemikhiqizo yezimonyo. Umswakama wayo omuhle kakhulu, ukuqina, ukwakheka kwefilimu kanye nezakhiwo zokuzinzisa kuyenza ibe isithako esibalulekile kumafomula wezimonyo. Ngokwesibonelo:

I-Moisturizer: Ama-cellulose ether angakha ifilimu evikelayo ukuze avale umswakama endaweni yesikhumba futhi asize isikhumba sihlale siswakama.

I-Thickener: Njenge-thickener, i-cellulose ether inikeza imikhiqizo yezimonyo ukungaguquguquki okufanele, okuyenza kube lula ukuyifaka nokumunca, futhi ithuthukise ulwazi lomsebenzisi.

I-Emulsifier: I-Cellulose ether ingazinzisa ama-emulsions, ivimbele ukuhlukaniswa kwamanzi kawoyela, futhi igcine ukuqina kwamafomula ezimonyo.

5. Imboni yokukhipha uwoyela

Ukusetshenziswa kwe-cellulose ether ekukhishweni kwamafutha kubonakala kakhulu ekulungiseni uketshezi lokumba kanye noketshezi oluqhekekayo. I-Cellulose ether ingasetshenziswa njenge-thickener, i-fluid loss reducer kanye ne-stabilizer ukuthuthukisa ukusebenza koketshezi lokumba. Ngokwesibonelo:

I-Thickener: I-Cellulose ether ingakhuphula i-viscosity yoketshezi lokumba, isize ukumisa okwesikhashana futhi ithwale ukusikwa kokubhoboza, futhi ivimbele ukubhidlika kodonga lomthombo.

Isinciphisi sokulahlekelwa uketshezi: Ngaphansi kwezimo lokushisa eliphezulu nezimo zengcindezi ephezulu, i-cellulose ether inganciphisa ukulahlekelwa okuwuketshezi lokumba, ivikele izendlalelo zikawoyela nezindonga zemithombo, futhi ithuthukise ukusebenza kahle kokumba. 

6. Imboni yokwenza amaphepha

Embonini yokwenza iphepha, i-cellulose ether isetshenziswa njenge-ejenti yokuqinisa, i-ejenti yokugqoka kanye ne-ejenti yokwenza ifilimu ephepheni. Ingathuthukisa amandla, isicwebezelisi nokushelela kwephepha futhi ithuthukise ukuguquguquka kokuphrinta. Ngokwesibonelo:

I-Reinforcer: I-Cellulose ether ingathuthukisa amandla okubopha phakathi kwemicu ye-pulp, yenze iphepha libe namandla futhi liqine.

I-ejenti yokuhlanganisa: Enqubweni yokumboza iphepha, i-cellulose ether ingasiza ukunamathela ukuthi kusatshalaliswe ngokulinganayo, kuthuthukise ukushelela nokuvumelana nezimo zokuphrinta.

I-ejenti eyenza ifilimu: I-Cellulose ether yenza ifilimu elincanyana phezu kwephepha, okwandisa ukumelana nomswakama kanye nokuqina kwephepha.

7. Ezinye izimboni

I-Cellulose ether isetshenziswa kabanzi kwezinye izimboni, njengezindwangu, isikhumba, izinto zikagesi, ukuvikelwa kwemvelo kanye neminye imikhakha. Embonini yendwangu, i-cellulose ether ingasetshenziselwa ukulinganisa intambo, ukuqeda indwangu kanye nokuhlakazwa kodayi; ekucutshungulweni kwesikhumba, i-cellulose ether ingasetshenziswa njenge-thickener ne-ejenti yokugqoka; emkhakheni wokuvikelwa kwemvelo, i-cellulose ether ingasetshenziswa njenge-flocculant kanye ne-adsorbent ekwelapheni kwamanzi ekuhlanzeni amanzi angcolile.

Njengomkhiqizo oguquliwe wezinto ze-polymer zemvelo, i-cellulose ether idlala indima ebalulekile emikhakheni eminingi efana nokwakhiwa, imithi, ukudla, izimonyo, ukukhishwa kwamafutha, ukwenza iphepha, njll ngokuqina kwayo okuhle kakhulu, ukugcinwa kwamanzi, ukwakheka kwefilimu, ukuzinza nezinye izakhiwo. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ububanzi bokusebenza nokusebenza kwama-cellulose ethers kusakhula. Ngokuzayo, ama-cellulose ethers kulindeleke ukuthi abonise amandla amaningi kanye nenani lesicelo ezintweni eziluhlaza nezivumelana nemvelo, amalungiselelo amasha emithi nezinto ezihlakaniphile.
