Malangizo a hydroxyethyl cellulose (hec)

Hydroxyethyl cellulose (hec) ndi polymer yosungunuka yamadzi nthawi zambiri imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kukhazikika, komanso kufota kwa makanema. Mukamagwira ntchito ndi Hec, kuonetsetsa kuti madzi oyenera ndikofunikira kuti akwaniritse zomwe mukufuna. Nawa maupangiri a Hecring Hec moyenera:

1. Gwiritsani ntchito madzi osungunuka: Yambani pogwiritsa ntchito madzi osungunuka kapena madzi owoneka bwino a HeCught Hec. Zosayera kapena zingwe zomwe zilipo m'madzi zimatha kukhudza ntchito hydration njira ndipo zimatha kubweretsa zotsatira zosagwirizana.
2. Njira Yokonzekera: Pali njira zosiyanasiyana za hecring Hec, kuphatikiza kuzizira kosakanikirana ndi kusakanikirana kotentha. Posakanizira kuzizira, pang'onopang'ono hec amawonjezeredwa kumadzi omwe akupitilira mpaka obalalika kwathunthu. Kusakaniza kotentha kumaphatikizapo kutentha madziwo kuzungulira 80-90 ° C kenako ndikuwonjezera pang'onopang'ono kuti akuwonjezere mpaka kupweteka kwathunthu. Kusankha njira kumatengera zofunikira mwatsatanetsatane.
3. Zowonjezera pang'onopang'ono: Kugwiritsa ntchito kusakanikirana kozizira kapena kusakaniza kotentha, ndikofunikira kuwonjezera hec pang'onopang'ono kumadzi pang'onopang'ono kumadzi mosalekeza. Izi zimathandiza kupewa mapangidwe a zotupa ndipo zimapangitsa kufaluzika kwa ma yunifolomu ya polymer.
4. Kusunthika: Kukhazikika koyenera ndikofunikira kwambiri chifukwa cha Hinako bwino. Gwiritsani ntchito chiphunzitso cha makina kapena chosakanizira chachikulu kwambiri kuti mutsimikizire kubalalitsidwa bwino komanso hydration ya polymer ya polymer. Pewani kugwiritsa ntchito zovuta kwambiri, chifukwa imatha kuyambitsa thovu la mpweya mu yankho.
5. Nthawi ya hydration: Lolani nthawi yokwanira hec kuti icheze kwathunthu. Kutengera ndi kalasi ya Hec ndi njira ya hydration njira yomwe imagwiritsidwa ntchito, iyi imatha kuyambira mphindi zingapo mpaka maola angapo. Tsatirani malingaliro a wopanga kalasi yapadera ya Hec ikugwiritsidwa ntchito.
6. Kuwongolera kutentha: Mukamagwiritsa ntchito kusakanikirana kotentha, yang'anani kutentha kwa madzi mosamala kuti mupewe kutentha, komwe kumatha kunyoza polymer. Sungani kutentha kwamadzi mkati mwa mawonekedwe oyenera mu hydration.
7. Kusintha kwa Ph: M'mapangidwe ena, kusintha pH yamadzi musanawonjezere Hec ikhoza kukulitsa hydration. Dinani ndi formipando kapena ikutchulanso zazogulitsa kuti zizitsogolera posintha kusintha kwa mawu.
8. Kuyesa ndi Kusintha: Mukatha kugwiritsa ntchito mankhwalawa, yesani ma visction ndi kusasinthika kwa yankho la hec kuti muwonetsetse kuti likugwirizana ndi zomwe mukufuna. Ngati pakufunika kusintha, madzi owonjezera kapena hec amatha kuwonjezeredwa pang'onopang'ono poyambitsa kukwaniritsa zomwe mukufuna.

Mwa kutsatira malangizowa, mutha kuonetsetsa kuti hydroxethyl cellulose (hec) ndikutha kuchitapo kanthu m'mapangidwe anu.
