Hydroxyethyl cellulose (hec) amagwiritsidwa ntchito powoloka kwambiri m'mafakitale osiyanasiyana chifukwa cha zinthu zomwe zimapangidwa ndi zida zamphamvu, kusungidwa kwamadzi, komanso luso lopanga mafilimu. Kubalalitsa Hec moyenera ndikofunikira kuti mutsimikizire kuti ndi kugwiritsa ntchito koyenera pamapulogalamu ngati utoto, zodzoladzola, mankhwala opanga mankhwala, komanso zinthu zomangamanga.
1. Kuzindikira hydroxyethyl cellulose (hec):
Hec ndi polymer osasunthika, osungunuka madzi ochokera ku cellulose.
Imatanthawuza mayankho omveka bwino m'madzi, kuwonetsa ma pseudoplactic olimbitsa thupi, kutanthauza kuti ma visccy amachepetsa ndikuwonjezeka.
2. Kusankha kwa zosungunulira:
Madzi ndiye zosungunulira zofala kwambiri zobalalitsa Hec chifukwa cha kukhazikika kwake.
Kutentha ndi Ph kwa zosungunulira kumatha kusintha kubala kwa hec. Nthawi zambiri, osalowerera nawo pang'ono alkaline ph amakonda.
3. Kukonzekera kubadwa kwa sing'anga:
Gwiritsani ntchito madzi owoneka bwino kapena madzi osungunuka kuti muchepetse zosafunikira zomwe zingakhudze disstation.
Khalanibe ndi kutentha kwa kusungunuka, nthawi zambiri kumapiri otentha kuti kutentha pang'ono (pafupifupi 20-40 ° C).
4. Kubalalitsa njira:
a. Kusakaniza dzanja lakumanja:
- Oyenera maphunziro ochepa.
- pang'onopang'ono onjezani ufa wa ufa kwa osungunulira pomwe amayambitsa mosalekeza kuti apewe kuyamwa.
- Onetsetsani kunyowetsa ufa musanayambe kusakaniza.
b. Makina Oyambitsa:
- Gwiritsani ntchito chiwonetsero cha makina okhala ndi tsamba kapena lothandiza.
- Sinthani liwiro losangalatsa kuti mukwaniritse zogawanika zopanda pake popanda kuyambitsa chithovu kapena chithovu cha mpweya.
c. Kusakaniza kwamtundu wapamwamba:
- Gwiritsani ntchito zosakaniza zapamwamba kwambiri ngati homogenizer kapena owonjezera othamanga kwambiri kuti abadwe bwino.
- Sinthanitsani mtengo wake kuti mupewe kuwonongeka kwa mamolekyulu.
d. Ultrasonication:
- Ikani akupanga mphamvu kuti muchepetse ma Agglomerates ndi kukulitsa kwatsopano.
- Thandizani magawo a sonication (pafupipafupi, mphamvu, nthawi) kuti musatenthe kapena kuwonongeka kwa yankho.
5. Malangizo a Kubalalika Kwambiri:
Onetsetsani kuti shec ufa zimawonjezedwa pang'onopang'ono kuti mupewe mapangidwe a lipemp.
Pewani kusintha kwadzidzidzi kwa kutentha kapena ph mu kubalalitsidwa, chifukwa kungakhudze Hec kusungunuka.
Lolani nthawi yokwanira ya hydration wathunthu ndikubalalitsa tinthu tating'onoting'ono.
Yang'anirani ma viscction pakubalalitsidwa kuti mukwaniritse zomwe mukufuna.
Gwiritsani ntchito zida zoyenerera ndi njira malinga ndi kuchuluka ndi zofunikira pakugwiritsa ntchito.
6. Kuwongolera kwapamwamba:
Chitani zowunikira zojambula zilizonse kapena zopangidwa ngati gel.
Kuyeza ma virucnce pogwiritsa ntchito wotchire kuti mutsimikizire kusagwirizana ndi zomwe mukufuna.
Khazikitsani mayeso a Rheological kuti muwone njira yoyenda ndi kukhazikika kwa discation.
7. Kusungira ndi kugwirana:
Sungani Hec Kubalalitsa mu zoyera zoyera, zotsekemera zowoneka bwino kuti zilepheretse kuipitsidwa ndi kunyowa.
Pewani kuwonekera kwa nthawi yayitali ku kutentha kwambiri kapena kuwala kwa dzuwa, komwe kumasokoneza polymer.
Zingwe zopezeka ndi chidziwitso choyenera kuphatikiza ndi nambala ya batch, kuphatikizira, ndi malo osungira.
8. Maganizo a chitetezo:
Tsatirani malangizo otetezedwa mukamayendetsa ufa ndi mayankho.
Gwiritsani ntchito zida zoyenera zoteteza (PPE) monga magolovesi ndi zigawenga zachitetezo.
Pewani kupuma kwa fumbi pogwiritsa ntchito malo otetezedwa kapena kugwiritsa ntchito kupuma ngati kuli kofunikira.
Kubalalitsa hydroxyethyl cellulose mwamphamvu kumafunikira kulingalira mosamalitsa kusankhidwa mosachedwa, obalalika, njira zapamwamba, komanso kusamala. Potsatira malangizo awa, mutha kuwonetsetsa kuti muchepetse bwino ma shec obalalika pamafashoni osiyanasiyana.
