Pa mawonekedwe a utoto, hydroxethyl cellulose (hec) ndi mtundu wofala komanso Rhelogy Mowaifier yomwe imatha kukonza zosunga, zomanga ndi zomanga zolimbitsa thupi. Pofuna kuwonjezera hydroxyethyl cellulose ku utoto ndikuwonetsetsa kuti imagwira ntchito bwino, masitepe ndi njira zina zofunika kutsatira. Njira yake ili motere:
1. Katundu wa hydroxyethyl cellulose
Hydroxyethyl cellulose ndi polymer yopanda madzi yosungunuka yamkuntho yokhala ndi mphamvu kwambiri, kupanga filimu, kusungunuka madzi, kuyimitsidwa komanso kuyimitsidwa. Amagwiritsidwa ntchito potengera utoto wochokera m'madzi, zomata, chramics, inks ndi zinthu zina. Imapezeka polowetsa gawo la magulu a hydroxyl pa ma cellulose ma celluose magemu, motero ili ndi madzi abwino.
Ntchito zazikuluzikulu za Hec mu zojambula ndi:
Zotsatira Zakulitsa: Onjezani mafayilo a utoto, kuletsa utoto kuti usakwapule, ndikupangitsa kukhala ndi zomangamanga zabwino.
Zotsatira zake: Imwani kufalikira ndikukhazikitsa tinthu tokhazikika monga mapepala ndi mafilimu kuti awalepheretse kukhazikika.
Zotsatira za madzi: kupititsa patsogolo madzi a filimu yokutidwa, kotukula nthawi, ndikusintha mphamvu yonyowa ya utoto.
Kuwongolera kwa Rhelogy: Sinthani madzi ndikuwongolera, ndikusintha burashi Marke pomanga.
2. Zowonjezera za ma hydroxyethyl cellulose
Gawo loletsa kusinthika pakugwira ntchito yeniyeni, hydroxyethyl cellulose imayenera kubalalika ndikusungunuka kudzera pakutha kwa chisanachitike. Pofuna kuonetsetsa kuti cellulose imatha kusewera bwino, nthawi zambiri imalimbikitsidwa kuti isungunuke m'madzi poyamba, m'malo mowonjezera mwachindunji. Malingaliro ake ali motere:
Sankhani zosungunulira zoyenera: Nthawi zambiri madzi owoneka bwino amagwiritsidwa ntchito ngati zosungunulira. Ngati pali ena osungunulira m'dongosolo lolumikizira, malo osungunuka amafunika kusinthidwa mogwirizana ndi zinthu za zosungunulira.
Pang'onopang'ono amawaza hydroxyathyl cellulose: pang'onopang'ono komanso mobwerezabwereza kuwaza hydrothyl cellulose poyambitsa madzi kuti aletse kubula. Liwiro losangalatsa lizikhala lochedwa kupewa kuchepa pang'onopang'ono kuchuluka kwa cellulose kapena kupanga "colloid" chifukwa cha mphamvu yonyansa kwambiri.
Kuyimirira kusinthidwa: Pambuyo pakuwaza hydroththyl cellulose, imafunikira kuti isayike kwakanthawi (nthawi zambiri mphindi 30 mpaka maola angapo) kuti muwonetsetse kuti cellulose ikhale yotupa kwathunthu ndikusungunuka m'madzi. Nthawi yakufanayo imatengera mtundu wa cellulose, kutentha kutentha ndi malo osangalatsa.
Sinthani kutentha kwa chisinthiko: Kuchulukitsa kutentha kumathandiza kuthamangitsa kusokonekera kwa hydroxethyl cellulose. Nthawi zambiri zimalimbikitsidwa kuwongolera kutentha pakati pa 20 ℃ -40 ℃. Kutentha kwambiri kumatha kuyambitsa kuwonongeka kwa celluluse kapena kusintha.
Kusintha mtengo wa pH ya njira yothetsera kusungunuka kwa hydroxethyl cellulose imagwirizana kwambiri ndi mtengo wa pH ya yankho. Nthawi zambiri imasungunuka bwino moyang'anizana ndi osalowerera ndale kapena pang'ono alkalinel, okhala ndi pH pakati pa 6-8. Pakusintha, mtengo wa pH umatha kusinthidwa ndikuwonjezera ammonia kapena zinthu zina zamchere monga kufunikira.
Kuonjezera hydroxyethyl cellulose yankho ku dongosolo lokutira mukafalikira, onjezerani yankho la chitolirocho. Panthawiyo, iyenera kuwonjezeredwa pang'onopang'ono ndikusunthidwa mosalekeza kuti mutsimikizire kusakanikirana kokwanira ndi matrix. Panthawi yosakanikirana, ndikofunikira kusankha liwiro labwino losangalatsa malingana ndi machitidwe osiyanasiyana kuti mupewe dongosolo lowonongeka kapena kuwonongeka kwa celluuse chifukwa cha mphamvu yotheratu.
Kusintha ma visccess pambuyo poti kuwonjezera hydroththyl cellulose, mafano ovala omwe amatha kuwongolera ndi kusintha kuchuluka komwe kumawonjezeredwa. Nthawi zambiri, kuchuluka kwa hydroxyethyl cellulose omwe amagwiritsidwa ntchito ali pakati pa 0,3% -1.0% (wachibale ndi zowonjezera zowonjezera zomwe zikuyenera kusinthaku kutengera zokambirana. Kuchuluka kwambiri kochulukirapo kungapangitse kuti kuyambitsidwa ndi chidwi kwambiri komanso kusungulumwa kwambiri, kumakhudzanso ntchito yomanga; Ngakhale zowonjezera sizitha kusewera gawo la kukula ndi kuyimitsidwa.
Khalidwe lokhazikika ndi mayeso osungika pambuyo powonjezera ma hydroththyl cellulose ndikusintha mawonekedwe ophatikizika, kuphatikizapo mayeso osungirako, enc. Nthawi yomweyo Onani kuwonongeka kwa chimbudzi mutayimirira kwa nthawi yayitali, kusintha kwa mafalo, etc., kuwunika kukhazikika kwa hydroxyethyl cellulose.
3. Kusamala
Pewani Kugamula: Panthawi yosungunuka, hydroxethyl cellulose ndizosavuta kuyamwa madzi ndikuwonetsetsa kuti muchepetse mapangidwe a zotupa. Uwu ndi ulalo wofunikira pa opareshoni, apo ayi zingakhudze kugunda kwa chilengedwe ndi kufanana.
Pewani mphamvu zapamwamba: Mukamawonjezera ma cellulose, liwiro losangalatsa siliyenera kukhala lalitali kwambiri kuti mupewe kuwononga ma cellulose ma celecular chifukwa cha mphamvu yolumikizira, yomwe imapangitsa kuchepa kwamphamvu. Kuphatikiza apo, popanga ma potsatira potsatira, kugwiritsa ntchito zida zankhondo zapamwamba ziyenera kupewedwanso momwe zingathere.
Lamulirani kutentha kwa chipongwe: mukatha kusungunula hydroththyl cellulose, kutentha kwamadzi sikuyenera kukhala lalitali kwambiri. Nthawi zambiri amalimbikitsidwa kuti azilamulira pa 20 ℃ -40 ℃. Pansi pa kutentha kwambiri, cellulose ingadetse, zomwe zimapangitsa kuchepa kwa zotsatira zake zazikulu ndi mafayilo.
Yankho losunga: hydroxyethyl cellulose mayankho nthawi zambiri amafunika kukonzedwa ndikugwiritsidwa ntchito nthawi yomweyo. Kusungika kwa nthawi yayitali kumakhudza ma victoni ake komanso kukhazikika. Nthawi zambiri zimalimbikitsidwa kukonzekera yankho lofunikira patsiku la penti kuti likhalebe ndi luso lake.
Kuphatikiza kwa hydroxyethyl cellulose ku utoto si njira yosakanikira chabe, komanso imafunikira kuphatikizidwa ndi zofunikira zenizeni ndikugwiritsa ntchito njira zogwiritsira ntchito kuti zitheke, kuyimitsidwa ndi madzi osungitsa amagwiritsidwa ntchito mokwanira. Panthawiyo, samalani ndi chibadwa chosungunuka chisanachitike, kuwongolera kutentha kwa kutentha ndi mtengo wa PH, komanso kusakaniza kwathunthu pambuyo powonjezera. Izi zimakhudza mwachindunji mtundu ndi kukhazikika kwa magwiridwe antchito.
