IHydroxYethyl Cellulose (HEC) iyinhlangano eguquguqukayo futhi esetshenziswa kabanzi e-ejenti yokuqina ngopende kanye nokumboza. Isebenza imisebenzi eminingi, ithuthukisa ukusebenza, ukuqina kanye nezindawo zohlelo lokusebenza zale mikhiqizo. Ngezansi umhlahlandlela ophelele wokuthi ungasebenzisa kanjani ngempumelelo i-hydroxyethyl cellulose kumapende nezingubo, ukumboza izinzuzo zawo, izindlela zokwakha, kanye nokucatshangelwa kokwakheka.
Izinzuzo ze-hydroxyethyl cellulose ku-piopers kanye nokumboza
Ukuguqulwa kwe-Rheelogy: I-HEC inika amandla ukugeleza okufiselekayo kanye nezimpawu zokulinganisa kupende kanye nokumboza, ukubasiza ukusakaza ngokulinganayo futhi kunciphise ukugcwala.
Ukuqinisekiswa kokuqina: Kuqinisa i-emulsion futhi kuvimbela ukuhlukaniswa kwesigaba, kuqinisekisa ukusatshalaliswa komfaniswano kwemibala kanye nabasizi.
Izakhiwo ezithuthukisiwe zesicelo: Ngokushintsha i-viscosity, i-HEC yenza ukuthi kube lula ukusebenzisa ipende, kungaba ngamabhulashi, i-roller, noma isifutho.
Ukugcinwa kwamanzi: I-HEC inezakhiwo ezinhle kakhulu zokugcina amanzi, ezibalulekile ukuze zilondoloze ukusebenziseka kwamapende nezingubo zokugqoka, ikakhulukazi ezimeni ezomile.
Ukuvumelana: I-HEC iyahambisana nohlu olubanzi lwama-solvents, imibala, nezinye izengezo, okwenza kube lula ukwakhiwa okuhlukahlukene.
Izindlela zohlelo lokusebenza
1. Ukuhlanganiswa komile
Indlela eyodwa evamile yokufaka i-HEC ibe ngamakamelo okupenda ngokuhlanganiswa owomile:
Isinyathelo 1: Kala inani elidingekayo le-HEC powder.
Isinyathelo 2: Kancane kancane engeza impuphu ye-HEC kwezinye izinto ezomile zokwakhiwa.
Isinyathelo 3: Qinisekisa ukuxubana kahle ukuze ugweme ukuqina.
Isinyathelo 4: Yengeza kancane amanzi noma i-solvent ngenkathi uxuba ngokuqhubekayo kuze kube yilapho i-hec igcwele ngokuphelele futhi ingxubevange enobukhulu iyatholakala.
Ukuhlanganiswa kwe-Dry kulungele ukwakheka lapho ukulawula okuqondile kokubonakala kudingeka kusukela ekuqaleni.
2. Ukulungiselela Isixazululo
Ilungiselela isixazululo sesitoko sokwenza kahle ngaphambi kokukufaka ekwakhekeni ngopende kungenye indlela ephumelelayo:
Isinyathelo 1: Shiya i-hec powder emanzini noma i-solvent oyifunayo, uqinisekise ukuthi uqhubeke nokuphazamiseka kokuvimbela ukwakheka kwenqwaba.
Isinyathelo 2: Vumela isikhathi esanele sokuthi i-HEC ibambe kahle ngokugcwele futhi ichithe, imvamisa amahora amaningi noma ubusuku obuningi.
Isinyathelo 3: Faka lesi sixazululo sesitoko ekwakhekeni kwepende ngenkathi uvusa kuze kube ukuvumelana okudingayo nezakhiwo kutholakala.
Le ndlela ivumela ukuphathwa okulula nokufakwa kwe-HEC, ikakhulukazi ekukhiqizweni okukhulu.
Ukucatshangelwa Kwamandla
1. Ukugxila
Ukuhlushwa kwe-HEC okudingekayo ekwakhekeni ngopende kuyahluka ngokuya ngokuvunywa okufunwayo kanye nendlela yesicelo:
Izicelo eziphansi ze-Shear: Nge-Brush noma uhlelo lokusebenza lwe-Roller, ukugcwaliseka okuphansi kwe-HEC (0.2-1,0% ngesisindo) kwanele ukufeza i-viscosity edingekayo.
Izicelo eziphezulu ze-Shear: Izicelo zokufafaza, ukugxilisa okuphezulu (1.0-2,0% ngesisindo) kungadingeka ukuvikela ukugcwala futhi kuqinisekiswe i-atomization enhle.
2. Ukulungiswa kwe-PH
I-PH yokwakheka ngopende ingathinta i-solubity kanye nokwenza i-HEC:
I-OPTIGAL PH Range: I-HEC isebenza kakhulu endaweni engathathi hlangothi ku-Alkaline Ph Range (PH 7-9).
Ukulungiswa: Uma ukwakhiwa kuyi-acidic kakhulu noma i-alkaline kakhulu, shintsha i-PH usebenzisa izengezo ezifanele ezinjenge-ammonia noma i-organic acid ukwenza kahle ukusebenza kwe-HEC.
3. Izinga lokushisa
Ukushisa kudlala indima ebalulekile ku-hydration kanye nokuchithwa kwe-HEC:
I-Cold Water Sluble: Amanye amabanga we-HEC aklanyelwe ukuncibilikisa emanzini abandayo, angenza lula inqubo yokuxuba.
Ukusheshisa kwamanzi okufudumele: Kwezinye izimo, ukusebenzisa amanzi afudumele kungasheshisa inqubo ye-hydration, kepha amazinga okushisa angaphezu kuka-60 ° C kufanele kugwenywe ukuvikela ukonakala kwe-polymer.
4. Ukuhambisana nezinye izithako
I-HEC idinga ukuhambelana nezinye izithako ekwakhekeni ukugwema izindaba ezinjengokuhlukaniswa kwe-gel noma ukuhlukaniswa kwesigaba:
I-Solvents: I-HEC iyahambelana nezinhlelo ezisuselwa emanzini nezinsulu-ze-solvent, kepha ukunakekelwa kufanele kuthathwe ukuze kuqinisekiswe ukuqondisisa okuphelele.
Ama-pigments kanye nama-fillers: I-HEC isiza ukuqinisa imibala kanye nama-fillers, iqinisekisa ukuhanjiswa okufanayo futhi kuvinjelwe ukuxazulula.
Ezinye izengezo: ukuba khona kwama-surfitiants, ama-dispersants, nezinye izengezo kungathinta i-viscosity nokuqina kokwakheka okuqinile kwe-hec.
Izeluleko Ezisebenzayo Zokusetshenziswa Okufanele
Ukuchithwa kwangaphambili: Ukuchithwa kwangaphambi kokuchithwa emanzini ngaphambi kokuyifaka ekwakhekeni ngopende kungasiza ekuqinisekiseni ukusatshalaliswa okufanayo futhi kuvikeleke ukuqina.
Ukungezwa okuhamba kancane: Uma ungeza i-HEC eya ekwakhiweni, yenza kancane kancane futhi ngokuphazamiseka okuqhubekayo ukugwema izigaxa.
Ukuxuba okuphezulu okusheheke
Ukulungiswa okukhuphukayo: Lungisa okuhlushwa kwe-HEC ngokwengeziwe, ukuhlola i-viscosity kanye nezinsizakusebenza zesicelo ngemuva kokunye okungeziwe ukufeza ukuvumelana okudingayo.
Izindaba ezijwayelekile nokuxazulula inkinga
Ukuthambisa: Uma i-HEC ingezwe ngokushesha okukhulu noma ngaphandle kokuxuba okwanele, ingakha izigaxa. Ukuvimbela lokhu, hlakaza i-hec emanzini kancane kancane ngenkathi kuvusa ngamandla.
I-Viscosity Engahambelani: Ukuhlukahluka kokushisa, i-PH, nejubane lokuxuba kungaholela ekubonakaleni okungahambisani. Bheka njalo bese ulungisa la mapharamitha ukuze ulondoloze ukufana.
I-Foaming: I-HEC ingangenisa umoya oya ekwakhiweni, okuholela emafweni. Sebenzisa ama-desoamers noma ama-anti-foaming agents ukunciphisa lolu daba.
IHydroxYethyl Cellulose iyingxenye ebalulekile ekwakheni ngopende kanye nokwakhiwa kwamanani ngenxa yekhono lawo lokuthuthukisa ukubonana, ukuqina kanye nezinto zohlelo lokusebenza. Ngokuqonda izindlela ezifanele zokufaka i-HEC, ukulungisa amapharamitha e-ackation, kanye nezinkinga zokuxazulula izingqinamba, abakhiqizi bangakha imikhiqizo yekhwalithi ephezulu, engaguquki, kanye nomsebenzisi. Noma ngabe nge-Dry Ehlanganisiwe noma Ukulungiselela Isixazululo, ukhiye ulele ekuxubeni okucashile, ukulungiswa kwe-PH, nokulawulwa kokushisa ukuze uzuze ngokuphelele izinzuzo ze-HEC.
