Hydroxyethyl cellulose (hec) ndi polymer polymer pormer yomwe idakhazikitsidwa ndi kusintha kwa mankhwala a cellulose yachilengedwe. Amagwiritsidwa ntchito kwambiri polankhula, mankhwala amchere tsiku ndi tsiku, zopangira zomanga ndi minda ina. Mitundu yosiyanasiyana ya hec imapangidwa ndi magawo monga digiri ya zolowa m'malo mwake (DS), molar m'malo (ms), mamasukidwe, etcc.
1. Gulu lokhala ndi digiri
Mulingo wazolowa (DS) amatanthauza kuchuluka kwa ma hydroxyethyl. Zosintha mu DS zimakhudza kusungunuka, mawonekedwe a ufa ndi magwiridwe antchito a HeC.
Mulingo wotsika wa Hec: DS ali pansipa 1.0. Mulingo wotsika wazolowetsa hec ali ndi kusungunuka kochepa ndipo nthawi zambiri amagwiritsidwa ntchito m'malo omwe amafunikira madzi omwe amafunikira madzi omwe amafunikira madzi, monga zomangira ndi zokutira zina.
Mlingo wapakatikati wa Hec: DS ali pakati pa 1.0 ndi 2.0. Hec yamtunduwu imakhala ndi madzi abwino osungunuka ndi mafayilo akulu, ndipo nthawi zambiri amagwiritsidwa ntchito muzogulitsa zamankhwala tsiku ndi tsiku (monga zotchinga ndi zodzola ndi emulsions.
Mlingo wapamwamba wa Shec: DS ili pamwamba 2.0. Mtundu wamtunduwu uli ndi madzi apamwamba amadzi ndipo nthawi zambiri amagwiritsidwa ntchito pogwiritsa ntchito zomwe zimafuna kuwonekera kwambiri komanso mafashoni apamwamba, otumphukira m'makampani azakudya, etc.
2. Gulu la molar
Molar Exft (MS) amatanthauza kuchuluka kwa ma hydroxyethyl mu gawo lililonse la glucose, koma limaphatikizapo zochita zingapo zomwe zimachitika panthawi yomwe idalowa m'malo. Mtengo wapamwamba wa MS, wabwino kwambiri wosungunuka wamadzi ndi kufooka kwa hec nthawi zambiri.
Msinji wotsika wa Sher: MS ndi ochepera 1. Mtundu wamtunduwu wa Hec ali ndi chisinthidwe pang'onopang'ono ndipo nthawi yayitali yopumira. Ndioyenera kugwiritsa ntchito magwiridwe omwe amafunikira kuchepetsedwa kapena kumasulidwa.
Pakati pa sing'anga yosiyanitsa HeC: MS ili pakati pa 1 ndi 2. Imakhala ndi chiwerengero chosinthika komanso chimagwiritsidwa ntchito kwambiri m'mankhwala amchere tsiku ndi tsiku, zokumba, ndi zomanga.
High Molar Hec: Ms ndi wamkulu kuposa 2. Imakhala ndi kuchuluka kwa chilengedwe komanso kusungunuka mwachangu, ndipo ndizoyenera kugwiritsa ntchito zosintha mosamala kapena zodzoladzola.
3. Gulu la mafayilo
Makulidwe a HeC ndi chizindikiro chofunikira kwambiri cha madzi ake mu yankho, nthawi zambiri kutengera kuchepa (kukhazikika) kwa yankho komanso muyeso wa miyeso (monga mtengo wonyezimira).
Ma viscence otsika hec: Makutu mu 1% yankho lake ndi ochepera 1000 MPPIC. IscCeness Isccess ndi yoyenera kugwiritsa ntchito ntchito ya rheology, wobalalitsa ndi mafuta, ndipo amagwiritsidwa ntchito kwambiri m'makampani tsiku lililonse, kukonzekera kwa chakudya, komanso kukonzekera kwa mankhwala.
Smonct Centerness Hec: Makutu mu 1% yankho ndi pakati pa 1000 ndi 4000 MPPIB. Mafayilo a ma virukidwe apakatikati amagwiritsidwa ntchito kwambiri pamaziko azifuti, ma inki osindikizira, ndi mafakitale opangira zida, ndikupangitsa kukula kwamphamvu ndi chiwongolero cha rheogy.
Kutalika kwa ma visn: Makutu mu 1% yankho lake ndi apamwamba kuposa 4000 mampa. Makina owoneka bwino a vicc amagwiritsidwa ntchito ngati thicker ndi ribilizer, yoyenera mavidiyo owoneka bwino komanso kuwonekera kwambiri, monga zofunda zapamwamba, zodzoladzola, komanso kugwiritsa ntchito mafakitale ena apadera.
4.. Gulu la Fomu
Hec imathanso kutchulidwanso molingana ndi mawonekedwe ake, omwe nthawi zambiri amakhudza kugwiritsa ntchito kwake ndikugwiritsa ntchito.
Hected Hec: Fomu yofala kwambiri, yosavuta kunyamula ndikugulitsa. Kugwiritsa ntchito mafakitale ambiri komanso tsiku lililonse kugwiritsa ntchito mankhwala, imafunikira kusakanikira madzi kuti apange yankho.
Granolar Hec: Granolar Hec ndizosavuta kusamalira hec kapena kusungunula ma helded hec, kuchepetsa mavuto a fumbi komanso yoyenera kupanga mafakitale akuluakulu.
Njira yothetsera Hec: Mapulogalamu ena omaliza, a Hec akhoza kuperekedwa mwachindunji
5. Hec yapadera
Palinso mafupa ena omwe akhala akusinthidwa mwanjira ina kapena kuchitiridwa zinthu mwakuthupi kuti akwaniritse zosowa zawo.
Makina opingasa a Hec: Madzi a Hec kukana ndi makina amakina asinthidwa ndi mankhwala obwera, ndipo ndizoyenera nthawi yofunikira kulimba komanso kulimba.
Kusintha kwa Hec: Kusinthanso kwa Carboxymethyty, ndi zina zotere.
Mec yosakanikirana: yophatikizidwa ndi masamba ena kapena magwiridwe antchito kuti apititse patsogolo ntchito yake, monga kugwiritsa ntchito kwa otsatsa ophatikizika.
Monga zosungunuka zamadzi zosungunuka, mitundu yosiyanasiyana ya hydroxthyl cellulose (hec) kuzolowera zofunikira pakusintha kudzera m'malo mwa zolowa m'malo mwazolowa, molar ndi mawonekedwe. Kuzindikira izi kumathandiza kusankha zinthu zabwino za hec pazothandiza kuti mupeze magwiridwe antchito komanso zotsatira. Kaya mumankhwala tsiku ndi tsiku, zopangira kapena mankhwala, hec imagwiritsidwa ntchito kwambiri chifukwa cha kukula kwake, zonyowa komanso makanema.
