Momwe mungapangire yankho la Hec?

Hec (hydroxyethyl cellulose) ndi chithunzi chodziwika bwino komanso chogwiritsidwa ntchito kwambiri pokonza njira, emulsions, ma gels, etc. imagwiritsidwa ntchito, mankhwala ena.

1. Kukonzekera
Musanayambe kukonza yankho la Hec, onetsetsani kuti mwakonza zinthu zotsatirazi ndi zida:
Hec ufa (ma hec omwe ali ndi ma vic nthawi zambiri amakhala ndi ma vincy amasuna, ndipo malo oyenera ayenera kusankhidwa malinga ndi pulogalamu inayake)
Zosungunulira (nthawi zambiri madzi oyera, madzi owoneka bwino kapena ma sodire omwe amagwiritsidwa ntchito)
Chida choyambitsa (magnetic chipwirikiti kapena woyambitsa makina)
Kutentha kuwongolera (monga kusamba kwamadzi)
Chidebe (galasi kapena pulasitiki yosangalatsa yokhala ndi voliyumu yokwanira)
Gawo lamagetsi

2. Njira zoyambira kukonzekera njira
2.1 Sankhani zosungunulira
Hec ali ndi kusungunuka bwino m'madzi, koma pofuna kupewa kuphatikizika kapena kufatsa kosagwirizana pakuwonongeka, gawo lowonjezeralo ndi liwiro losangalatsa liyenera kuwongolera mosamala. Madzi owongoka nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira. Ngati mukufuna kukonzekera kusintha kwa organic system Hec yankho, muyenera kusankha dongosolo labwino (monga njira yosakanikirana ya Mowa ndi madzi).

2.2 Kutentha madzi
Kufalikira kwa Hec kumakhudzana ndi kutentha kwamadzi. Pofuna kuthamangitsa kuwonongeka kwa Hec, madzi ofunda (pafupifupi 50 ° C) nthawi zambiri amagwiritsidwa ntchito, koma osati apamwamba kwambiri kupewa kukhudza magwiridwe antchito a HeC. Ikani madzi owonetseredwa mu chidebe, yambani kutentha, ndikusintha kukhala kutentha koyenera (40-50 ° C).

2.3 Kusunthira kwakanthawi
Madzi akutentha, kuyamba kusuntha. Chida chosangalatsa chitha kukhala chipwirikiti kapena woyambitsa makina. Liwiro losangalatsa losangalatsa liyenera kusungidwa kuti mupewe kuwononga madzi osakanikirana.

2.4 Tsegulani pang'onopang'ono ufa
Madzi akatenthedwa 40-50 ° C, kuyamba kuwonjezera pang'onopang'ono kufalitsa ufa wa Hec. Pofuna kupewa ufa kuwuluka, uyenera kuwazidwa pang'onopang'ono mukamayambitsa. Njira zotsatirazi zitha kugwiritsidwa ntchito kukonza zofalitsa:

Onjezani mu ma batche: Musathire zonse nthawi imodzi, mutha kuwonjezera zochepa kangapo, ndipo dikirani mpaka ufa umabalalika pambuyo pa kuwonjezera kulikonse musanawonjezere nthawi ina.
SAME: kuwaza ufa ufa kudzera mu suna m'madzi kuti athandize kuchepetsa ufa wa ufa.
Sinthani liwiro losangalatsa: Mukamawaza ufa, sinthani liwiro loyambitsa moyenera kuti musunge mphamvu inayake, yomwe ili yabwino kufalikira ndi kulumikizidwa kwa ma yunifolomu ya cellulose.

2.5 Pitilizani kusangalatsa mpaka kusungunuka kwathunthu
Kuwonongeka kwa Hec ndi gawo pang'onopang'ono. Monga ufa umabalalika ndikusungunuka, yankho lakelo lidzakulumira. Kuti muwonetsetse kuti hec imasungunuka kwathunthu kwa maola 1-2, ndipo nthawi yakeyo imatengera mawonekedwe a yankho ndi kuchuluka kwa hec yomwe imagwiritsidwa ntchito. Ngati ma pulmps akuwonekera mu yankho kapena yankho lakelo ndi losasinthika, nthawi yosangalatsa imatha kukulitsidwa kapena kutentha kwa madzi kungawonjezeke pang'ono kuposa 50 ° C.

2.6 Kuzizira
Msuzi ukasungunuka kwathunthu, siyani kutentha ndikupitilizabe kulimbikitsa, ndipo lolani yankho pang'onopang'ono limele pang'onopang'ono kutentha kwa firiji. Panthawi yozizira, mafayilo a yankho amatha kupitiliza mpaka kufika kukhazikika.

3. Sinthani kuchuluka kwa yankho
Kukhazikika kwa the HeC yankho nthawi zambiri kumasinthidwa malinga ndi pulogalamu inayake. Zofananira zofananira za hec ndende ndi 0,5% ~ 5%, ndipo mtengo wakeyo umatsimikiziridwa molingana ndi zotsatira zake. Izi ndi njira yowerengera ndalama zofunikira

Hec:

Kuchuluka kwa hec (g) = voliyumu yothetsera (ml) × yofunikira ndende (%)

Mwachitsanzo, ngati mukufuna kukonza 1000ml ya 1% Hec yankho, muyenera 10g ufa wa Hec.

Ngati mamasukidwe a yankholi ndi okwera kwambiri kapena otsika kwambiri mutakonzekera, mutha kusintha mwanjira zotsatirazi:

Kukula: Ngati ma viscy sikokwanira, onjezerani ufa wochepa wa HIC. Samalani kuti muwonjezere m'matumba kuti mupewe kubula.

Kuchenjera: Ngati mamasukidwe a njirayi ndi okwera kwambiri, onjezerani madzi owonetsera kuti muchepetse moyenera.

4. Kusamba
Kuti muwonetsetse kufanana ndi kuyera kwa yankho lomaliza, imatha kusefedwa kudzera mu suna kapena zosefera. Kusefukira kumatha kuchotsa tinthu tating'onoting'ono kapena zosafunikira, makamaka pofuna kugwiritsa ntchito (monga mankhwala osokoneza bongo kapena zodzoladzola).

5. Kusungika ndikusungidwa
Njira yokonzekereratu ya HeC iyenera kusindikizidwa kuti isateteze ndi kuipitsidwa. Ndikulimbikitsidwa kusunga malo ozizira komanso owuma kutali ndi dzuwa. Ngati yankho limasungidwa kwa nthawi yayitali, kuipitsidwa kwachipongwe kungachitike. Ndikulimbikitsidwa kuwonjezera kuchuluka koyenera (monga phenoxyethanol, methylisothiazozolinone, etc.) monga kufunikira.

6. Kusamala
Pewani kuphatikizika: Hec ufa ndikosavuta kwa anglomerate m'madzi, makamaka powonjezera mwachangu kapena kusunthika sikukwanira. Ndikulimbikitsidwa kugwiritsa ntchito njira yowonjezera m'matumba ndikusintha liwiro losangalatsa moyenerera kuti ufa umabalalika.
Mlingo wa IscCon: Ngati kuli kotheka, mafayilo amatha kuyerekezera kugwiritsa ntchito zida monga njira yozungulira ngati ikuwonetsetsa kuti ikukwaniritsa zofunikira zina.
Kutetezedwa: Ngati hec yankho limasungidwa kwa nthawi yayitali, kuwonjezera kwa oteteza osungirako ndikofunikira kuti muchepetse kukula kwa tizilombo tating'onoting'ono mu yankho ndikupangitsa kuti yankho lithe.

Chinsinsi chopanga Hec yankho ndikutha kuwongolera kutentha, liwiro losangalatsa ndi njira yowonjezera ya hec ufa kuti awonetsetse kuti hec imasungunuka kwathunthu ndikusungunuka kwathunthu. Kugawanika kuyenera kulephera panthawi yosungunuka, ndipo mtundu wa yankho kumatha kusintha mwa kusefa ngati kuli kofunikira. Pambuyo panzeru maluso awa, mutha kukonzekera mayankho a AHC omwe amakumana ndi zosowa zanu ndikuwagwiritsa ntchito mankhwala osiyanasiyana a mafakitale komanso tsiku lililonse.
