b.Isakhono sokwenza ifilimu:

I-cellulose ethers inekhono lokwenza ifilimu ezinceda ukuphucula iipropati ezingaphezulu kunye nokuphucula umgangatho wephepha.

c.Ukuqina kunye nokudibanisa:

I-cellulose ethers isebenza njengama-thickeners, inyusa i-viscosity ye-pulp.Olu phawu lunenzuzo ukulawula ukuhamba kwe-pulp ngexesha lenkqubo yokwenza iphepha.Ukongezelela, zenza njengama-adhesives, ukukhuthaza ukunamathela kweefibers ephepheni.

d.Izinzile:

Ezi ether zibonisa ukuzinza phantsi kweemeko ezahlukeneyo, kubandakanywa ubushushu kunye nokutshintsha kwe-pH, kunceda ukuphucula ukuthembeka kwabo kwinkqubo yokwenza iphepha.

3..Indima ye-cellulose ethers kushishino lwephepha:

a.Ugcino kunye nokuphuculwa kwamanzi okuhambisa amanzi:

I-cellulose ethers iyaziwa ngokukwazi ukunyusa ukugcinwa kwe-pulp kunye nokukhupha amanzi ngexesha lenkqubo yokwenza iphepha.Oku kuphucula ukucaca kwephepha kunye nokunciphisa ukusetyenziswa kwamanzi.

b.Ukomeleza:

Ukongezwa kwe-cellulose ethers kuphucula iimpawu zamandla ephepha, kubandakanywa amandla okuqina, amandla okuqhuma kunye nokumelana nokukrazula.Oku kubaluleke kakhulu ekuveliseni iphepha elikumgangatho ophezulu ofanelekileyo kwiinkqubo ezahlukeneyo.

c.Ubungakanani bomphezulu:

I-cellulose ethers isetyenziswa kwimixube yobungakanani bomphezulu ukunceda ukudala umphezulu ogudileyo, ofanayo ephepheni.Oku kwandisa ukuprintwa kunye nokubonakala kwemveliso yokugqibela.

d.Ulawulo lokufunxa i-inki:

Kwizicelo zoshicilelo, i-cellulose ethers inceda ukulawula ukufunxwa kwe-inki, ukuthintela ukusasazwa ngokugqithisileyo kunye nokuqinisekisa umgangatho woshicilelo ococekileyo.

e.Ukulawulwa kwe-porosity yephepha:

I-cellulose ethers inceda ukulawula i-porosity yephepha ngokuchaphazela ukubunjwa kwesakhiwo sephepha.Oku kubalulekile kwizicelo ezifana nephepha lokucoca.

f.Ukugcina uncedo kwizihluzi kunye nezongezo:

I-cellulose ethers isebenza njengezixhobo zokugcina izihluzi kunye nezinye izongezo kwinkqubo yokwenza iphepha.Oku kuqinisekisa ukuba ezi zithako zigcinwa ngokufanelekileyo ngaphakathi kwesakhiwo sephepha.

4. Ukusetyenziswa kwe-cellulose ether kwiimveliso zephepha:

a.Iphepha lokuprinta nokubhala:

I-cellulose ethers isetyenziswa ngokubanzi kwimveliso yokuprinta kunye namaphepha okubhala ukuphumeza umgangatho ofanelekileyo wokushicilela, ukugudisa kunye neempawu eziphezulu.

b.Iphepha lokusonga:

Kumaphepha okupakisha, i-cellulose ethers inceda ukwandisa amandla, ukuqinisekisa ukuba iphepha linokumelana nobunzima bokupakisha kunye nokuthunyelwa.

c.Isicatshulwa:

I-cellulose ethers inika iphepha langasese ukuthamba, ukomelela kunye ne-absorbency.Ezi mpawu zibalulekile kwizicubu zobuso, iphepha langasese kunye nezinye iimveliso zethishu.

d.Iphepha elikhethekileyo:

Amaphepha akhethekileyo, afana nephepha lokucoca, iphepha lokugquma umbane, kunye nephepha lezonyango, ahlala edibanisa i-cellulose ethers ukuhlangabezana neemfuno ezithile zokusebenza.

5. Iingqwalasela zokusingqongileyo:

a.Ukonakala kwezinto eziphilayo:

I-cellulose ethers idla ngokubola, ngokuhambelana nemfuno ekhulayo yoshishino lwephepha yezenzo ezihambelana nokusingqongileyo kunye nezizinzileyo.

b.Umoya ovuselelekayo:

Ekubeni i-cellulose ethers iphuma kwi-pulp yokhuni, isibonelelo esihlaziyiweyo, ukusetyenziswa kwabo kunegalelo ekuzinzeni kwenkqubo yokuvelisa iphepha.

I-cellulose ethers idlala indima eninzi kumashishini ephepha, echaphazela yonke imiba yokuvelisa iphepha kunye nokunceda ukudala iimveliso zephepha eziphezulu.Ukunyibilika kwabo kwamanzi, amandla okwenza ifilim, kunye nezinye iipropathi ezikhethekileyo zenza ukuba zibe izongezo ezixabisekileyo kwinkqubo yokwenza iphepha.Njengoko ishishini lamaphepha liqhubeka nokuguquka, ukubaluleka kwe-cellulose ethers ekuphuculeni umgangatho wephepha, ukusebenza kunye nokuzinza kunokwenzeka ukuba kuqhubeke kwaye kukhule.
