Ama-cellulose ether adlala indima ebalulekile embonini yamaphepha, esiza kuzo zonke izici zokukhiqiza iphepha kanye nokwenza ngcono izinga nokusebenza kwemikhiqizo yephepha.
1. Isingeniso se-cellulose ether:
I-cellulose ethers iyiqembu lama-polymers ancibilika emanzini atholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Umthombo oyinhloko wama-cellulose ethers yi-wood pulp, futhi asetshenziswa kakhulu ezimbonini ezihlukahlukene, kuhlanganise nemithi, ukudla, ukwakhiwa, futhi ikakhulukazi imboni yephepha.
2. Izici ze-cellulose ether:
a.Ukuncibilika kwamanzi:
Enye yezinto ezibalulekile zama-cellulose ethers ukuncibilika kwawo emanzini.Lesi sakhiwo sibenza bahlakazeke kalula emanzini, kube lula ukuhlanganiswa kwabo ku-pulp.
b.Amandla okwenza ifilimu:
Ama-cellulose ethers anamakhono okwenza ifilimu asiza ukuthuthukisa izakhiwo ezingaphezulu futhi athuthukise ikhwalithi yonke yephepha.
c.Ukuqina nokuqina:
Ama-cellulose ethers enza njengama-thickeners, okwandisa i-viscosity ye-pulp.Lesi sici sinenzuzo ukulawula ukugeleza kwe-pulp ngesikhathi senqubo yokwenza iphepha.Ngaphezu kwalokho, benza njengama-adhesives, bakhuthaza ukunamathela kwemicu ephepheni.
d.Izinzile:
Lawa ma-ether abonisa ukuzinza ngaphansi kwezimo ezihlukahlukene, okuhlanganisa izinga lokushisa nezinguquko ze-pH, okusiza ukuthuthukisa ukwethembeka kwawo enqubweni yokwenza iphepha.
3..Iqhaza lama-cellulose ethers embonini yephepha:
a.Ukugcinwa nokuthuthukiswa kwe-drainage:
Ama-cellulose ethers aziwa ngekhono lawo lokuthuthukisa ukugcinwa kwe-pulp kanye nokukhipha amanzi ngesikhathi senqubo yokwenza iphepha.Lokhu kuthuthukisa ukucaba kwephepha futhi kunciphisa ukusetshenziswa kwamanzi.
b.Ukuqinisa:
Ukwengezwa kwe-cellulose ethers kuthuthukisa izakhiwo zamandla zephepha, okuhlanganisa amandla aqinile, amandla okuqhuma kanye nokumelana nezinyembezi.Lokhu kubaluleke kakhulu ekukhiqizeni iphepha lekhwalithi ephezulu elifanele ukusetshenziswa okuhlukahlukene.
c.Usayizi womphezulu:
Ama-cellulose ethers asetshenziswa ekwenziweni kosayizi ongaphezulu ukusiza ukudala indawo ebushelelezi, efanayo ephepheni.Lokhu kuthuthukisa ukuphrinta nokubukeka komkhiqizo wokugcina.
d.Ukulawula ukumuncwa kukayinki:
Ezinhlelweni zokuphrinta, ama-cellulose ether asiza ukulawula ukumuncwa kukayinki, avimbele ukusabalala ngokweqile futhi aqinisekise ikhwalithi yokuphrinta ehlanzekile.
e.Ukulawulwa kwe-porosity yephepha:
I-cellulose ethers isiza ukulawula i-porosity yephepha ngokuthinta ukwakheka kwesakhiwo sephepha.Lokhu kubalulekile ezinhlelweni ezifana nephepha lokuhlunga.
f.Izinsiza zokugcina kuma-filler nezithasiselo:
Ama-cellulose ethers asebenza njengezinsiza zokugcina izigcwalisi nezinye izithasiselo kunqubo yokwenza iphepha.Lokhu kuqinisekisa ukuthi lezi zithako zigcinwa ngokuphumelelayo ngaphakathi kwesakhiwo sephepha.
4. Ukusetshenziswa kwe-cellulose ether emikhiqizweni yephepha:
a.Iphepha lokuphrinta nokubhala:
Ama-cellulose ether asetshenziswa kakhulu ekukhiqizeni amaphepha okuphrinta nokubhala ukuze kuzuzwe ikhwalithi yokuphrinta efanelekile, ukushelela kanye nezakhiwo ezingaphezulu.
b.Iphepha lokugoqa:
Emaphepheni okupakisha, i-cellulose ethers isiza ukukhulisa amandla, iqinisekisa ukuthi iphepha likwazi ukumelana nobunzima bokupakishwa nokuthunyelwa.
c.Izicubu:
Ama-cellulose ether anika iphepha lasendlini yangasese ukuthamba kwalo, amandla kanye nokumunca.Lezi zakhiwo zibalulekile kuzicubu zobuso, iphepha lasendlini yangasese kanye neminye imikhiqizo yezicubu.
d.Iphepha elikhethekile:
Amaphepha akhethekile, njengephepha lokuhlunga, iphepha lokufakwa kukagesi, nephepha lezokwelapha, ngokuvamile ahlanganisa ama-cellulose ether ukuze ahlangabezane nezimfuneko ezithile zokusebenza.
5. Ukucatshangelwa kwemvelo:
a.I-Biodegradability:
Ama-cellulose ether ngokuvamile angonakaliswa yizinto eziphilayo, ngokuhambisana nesidingo esikhulayo semboni yephepha semikhuba ehambisana nemvelo nesimeme.
b.Amandla avuselelekayo:
Njengoba i-cellulose ethers itholakala ku-wood pulp, insiza evuselelekayo, ukusetshenziswa kwayo kunomthelela ekusimameni kwenqubo yokukhiqiza iphepha.
I-cellulose ethers idlala indima ehlukahlukene embonini yephepha, ithinta zonke izici zokukhiqiza iphepha futhi isiza ukudala imikhiqizo yephepha ephezulu.Ukuncibilika kwawo kwamanzi, ikhono lokwenza ifilimu, nezinye izinto eziyingqayizivele kuzenza zibe izithasiselo ezibalulekile enqubweni yokwenza iphepha.Njengoba imboni yephepha iqhubeka nokuthuthuka, ukubaluleka kwe-cellulose ethers ekuthuthukiseni ikhwalithi yephepha, ukusebenza nokusimama kungenzeka kuqhubeke futhi kukhule.
