I-cellulose ethers, njenge-methyl cellulose (MC), i-hydroxypropyl methylcellulose (HPMC), kunye ne-ethyl cellulose (EC), isetyenziswa ngokubanzi njengezibophelelo kwiingubo ngenxa yeempawu zabo ezizodwa kunye neenzuzo ezininzi. Nalu ujongo olubanzi olugubungela imiba eyahlukeneyo:
Ukuqulunqwa kwefilimu: I-ethers ye-cellulose inegalelo ekubunjweni kwefilimu eqhubekayo, efanayo xa isetyenziswe njengezibophelelo kwiingubo. Le filimu ibonelela ngomqobo okhusela i-substrate kwizinto zokusingqongileyo ezifana nokufuma, iikhemikhali, kunye nemitha ye-UV.
Ukubambelela: Ezi zibophelelo ziphucula ukunamathela phakathi kwengubo kunye ne-substrate, ukukhuthaza ukuqina kunye nokuphila ixesha elide kwenkqubo yokugquma. Ukuncamathela okuphuculweyo kukhokelela ekunciphiseni amathuba okugqabhuka, ukugqabhuka, okanye ukuxobuka ngokuhamba kwexesha.
Ukutyebisa kunye noLawulo lweRheology: I-ethers ye-cellulose ibonisa iimpawu ezibalaseleyo zokutyeba, ezivumela ulawulo olungcono kwi-viscosity kunye ne-rheology yokwakheka kwe-coating. Oku kunceda ekuthinteleni ukuthoba okanye ukuvuza ngexesha lokufakwa kwesicelo, kuqinisekisa ukugqunywa kunye nokufana.
Ukugcinwa kwamanzi: Enye yeenzuzo eziphambili ze-cellulose ethers kukukwazi kwabo ukugcina amanzi ngaphakathi kwe-coating formulation. Oku kwandisa ixesha lokumisa, ukuququzelela ukulinganisa okufanelekileyo kunye nokunciphisa umngcipheko weziphene zomhlaba ezifana ne-cratering okanye i-orange peel effect.
Ukuphuculwa kokuSebenza: Iingubo eziqulethe i-cellulose ethers zilula ukuphatha nokusebenzisa, ngenxa yokuphucula ukusebenza kwazo kunye nokunciphisa ukuthambekela kokutshiza okanye ukutshiza ngexesha lokusetyenziswa. Oku kwandisa ukusebenza kakuhle kwenkqubo yokwaleka.
Ukuzinza okuphuculweyo: I-ethers ye-cellulose igalelo ekuzinzeni kweendlela zokugubungela ngokuthintela ukuhlukana kwesigaba, ukuchithwa, okanye ukuxutywa kwee-pigments kunye nezinye izongezo. Oku kuqinisekisa ukusebenza okuhambelanayo kunye nokubonakala kwengubo ngexesha.
Ukuhambelana nezinye izongezo: Ezi zibophelelo zihambelana noluhlu olubanzi lwezongezo ezisetyenziswa ngokuqhelekileyo kwiingubo, ezifana ne-pigments, fillers, dispersants, kunye ne-defoamers. Oku kuguquguquka kuvumela ukuqulunqwa kweengubo ezineepropati ezilungiselelwe ukuhlangabezana neemfuno ezithile zesicelo.
UBungane kokusiNgqongileyo: I-cellulose ethers ithathwe kwimithombo ehlaziyekayo, ikakhulu i-cellulose efunyenwe kwimicu yezityalo. Ngaloo ndlela, zijongwa njengezinye iindlela ezihambelana nokusingqongileyo kwii-synthetic binders ezivela kwi-petrochemicals.
Ukuthotyelwa koLawulo: Ii-ethers ezininzi ze-cellulose ezisetyenziswa kwiingubo zithobela imigangatho yolawulo yokhuseleko kunye nokukhuselwa kwendalo, njengezithintelo zokukhutshwa kwe-volatile organic compound (VOC) kunye nezinto ezinobungozi. Oku kuqinisekisa ukuba iingubo ezenziwe kunye nezi zibophelelo zihlangabezana neemfuno zokulawula kwiimarike ezahlukeneyo.
Uluhlu olubanzi lweSicelo: I-ethers ye-cellulose ifumana izicelo kwiinkqubo ezininzi zokugubungela, kubandakanywa iipeyinti zezakhiwo, iingubo zemizi-mveliso, iingubo zokhuni, kunye neengubo ezikhethekileyo ezifana neenki zokuprinta kunye ne-adhesives. Ukuguquguquka kwabo kubenza babe zizinto eziyimfuneko kwishishini lezogquma.
I-cellulose ethers inika intaphane yeenzuzo njengezibophelelo kwiingubo, ukusuka ekuphuculweni kokwenziwa kwefilimu kunye nokubambelela ukuzinza okuphuculweyo kunye nobuhlobo bendalo. Ukuguquguquka kwabo kunye nokuhambelana nezinye izongezo kubenza babe ngamacandelo abalulekileyo ekuqulunqweni kweengubo eziphezulu zokusebenza kwezicelo ezahlukeneyo.
