3.I-Hydroxyethyl Cellulose (HEC) Izicelo:
Kwipeyinti esekwe emanzini, idlala indima yokusasaza kunye nokukhusela iijeli, iphucula uzinzo lokusabela kwenkqubo ye-agglomerate, iqinisekisa ukuhanjiswa okulinganayo kwebala kunye nokuxutywa, kunye nokubonelela ngesiphumo sokujiya, ukuphucula ubumanzi.
Kwi-oyile yokomba, isetyenziswa njenge-stabilizer kunye ne-ejenti yokuqina, iarhente yokuthambisa yokomba umthombo, ukugqiba kunye nokudibanisa ukunika uludaka oluludaka olululo kunye nokuzinza.
Ekwakhiweni, i-HEC ingasetyenziswa njenge-ejenti yokuqina kunye ne-ejenti edibeneyo yokuphucula i-fluidity kunye nokusebenza, ukunyusa amandla okuqala e-gelling kwaye ugweme ukuqhekeka.
Ekuxutyweni nasekudibaniseni udaka, ngokucacileyo kunokunyusa ukubamba kwamanzi kunye namandla okuhambelana.
Kwimichiza yokusetyenziswa kwemihla ngemihla efana nentlama yamazinyo inika ipropathi efanelekileyo yomzimba kunye neekhemikhali, iyenza ibentle kwimilo, ixesha elide lokugcina, yome kwaye ingene.
Kwintsimi yezithambiso, inokonyusa ubuninzi bezinto eziphathekayo, yongeza ukuthambisa kunye nokugudiswa.
Ngaphandle koko, inesicelo esibanzi kwi-inki, ukudaya kwelaphu kunye nokuprinta, ukwenza iphepha, amayeza, ukutya, ezolimo njl.
4.Hydroxyethyl Cellulose (HEC) Ukusebenzisa indlela :
Indlela yokuqala: Faka ngokuthe ngqo
1. Galela amanzi acocekileyo kwi-emele ene-stirrer.
2. Ekuqaleni shukumisa kancinane, usasaze ngokulinganayo iHEC kwisisombululo.
3. Gxuma de zonke iigranuli zeHEC zimanziswe ngokupheleleyo.
4. Okokuqala faka i-anti-mildew agent, emva koko wongeze izongezo ezifana ne-pigment, i-disperser njl.
5. Qhubeka nokuvuselela de yonke i-HEC kunye ne-additives zinyibilike ngokupheleleyo (i-viscosity kwisisombululo ngokucacileyo iyanda), uze ufake ezinye izithako zokusabela.
Indlela yesiBini: Lungisa utywala bukaMama ukuze busetyenziswe
Okokuqala lungisa utywala oomama obunzima, emva koko bubeke kwimveliso. Inzuzo yendlela kukuguquguquka, utywala bunokuthi bubekwe ngokuthe ngqo kwimveliso. Inkqubo kunye nendlela yokusebenzisa iyafana ne-1-4 kwindlela (Ⅰ), ibe qinisekisa uvuse ude unyibilike ngokupheleleyo ube sisinyibiliko esincangathi nesingqindilili kwaye ufake into elwa nokungunda kutywala benina kwangoko.
Indlela yesiThathu: Lungiselela izinto ezifana neGruel ukuze zisetyenziswe
Ekubeni i-solvents ye-organic i-non-solvents ye-HEC, ingasetyenziselwa ukulungisa izinto ezinjenge-gruel.Ezona zisetyenziswa kakhulu yi-ethylene glycol, ipropylene glycol kunye ne-agent-forming agent (i-hexamethylene-glycol, i-diethyl glycol butyl acetate njl.) amanzi, inokulungiswa kunye kunye nezinyibilikisi eziphilayo zibe yimathiriyeli efana negruel.
Izinto ezifana ne-Gruel zinokufakwa kwimveliso kuba i-HEC kwizinto ezifana ne-gruel zifakwe ngokupheleleyo kwaye zidumbile, zifakwe kwimveliso zinyibilika ngokukhawuleza kwaye zikhuthaze ukujiya, kodwa qhubeka uvuselela de inyibilike ngokupheleleyo.
Ngokuqhelekileyo i-gruel-like material ifunyenwe ngokuxuba i-solvent ephilayo okanye amanzi abandayo kunye ne-HEC ngomlinganiselo we-6: 1, emva kwe-5-30 imizuzu ye-HEC i-hydrolyzes kwaye ngokuphawulekayo i-swells.Indlela ayithathwanga ehlotyeni ngenxa yemozulu eshushu.
5.ISikhokelo seSicelo samaShishini epeyinti
Iziphumo eziphezulu zokutyebisa
I-Hydroxyethy Cellulose ibonelela ngeepeyinti zelatex ngakumbi iipeyinti eziphezulu zePVA ezisebenza ngokugqwesileyo.Xa ipeyinti intlama engqindilili, akukho flocculation iya kwenzeka.
I-Hydroxyethy Cellulose ineziphumo eziphezulu zokujiya, ngoko inokunciphisa idosi, iphucule ukusebenza kakuhle kweendleko zokuyila, kwaye yandise ukuxhathisa kokuhlanjwa kwepeyinti.
IiPropati ezigqwesileyo zeRheological
Isisombululo samanzi se-Hydroxyethy Cellulose yinkqubo engeyiyo ye-Newtonian, kwaye iipropati zesisombululo zibizwa ngokuba yi-thixotropy.
Kwimeko emileyo, emva kokuba imveliso ichithwe ngokupheleleyo, inkqubo yokugquma inokugcina eyona meko igqwesileyo kunye nemeko yokuvula.
Kwimeko yokulahla, inkqubo inokugcina i-viscosity ephakathi, yenza iimveliso ezinobumanzi obugqwesileyo, kwaye zingatshizi.
Ngexesha lokuxubha kunye ne-roller coating, imveliso ilula ukusasazeka kwi-substrate, ngoko ilungele ukwakhiwa, kwaye okwangoku, inokumelana nokutshiza okulungileyo.
Ekugqibeleni, emva kokugqitywa kwepeyinti, i-viscosity yenkqubo iya kubuyiselwa ngokukhawuleza, kwaye ipeyinti iya kuvelisa ngokukhawuleza ipropathi ephazamisayo.
Ukusasazwa kunye nokunyibilika
I-Hydroxyethy Cellulose yonke iphathwa ngokuchithwa kokulibaziseka, kwaye kwimeko yokongeza ipowder eyomileyo, inokuthintela ngokufanelekileyo i-caking kwaye uqinisekise ukuba i-hydration iqala emva kokusasazwa okwaneleyo kwe-HEC powder.
I-Hydroxyethy Cellulose emva konyango olufanelekileyo lomphezulu inokulawula kakuhle izinga lokuchithwa kunye nesantya sokwanda kwe-viscosity yemveliso.
Uzinzo lokuGcina
I-Hydroxyethy Cellulose inokusebenza kakuhle ukumelana nokungunda, ibonelela ngexesha elaneleyo lokugcina iipeyinti, kwaye ikhusela ngokufanelekileyo ukuhlaliswa kwebala kunye nezihluzi.a
