Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ndi yoyera kapena yachikasu chopepuka, yopanda fungo, yopanda poizoni, yopangidwa ndi ulusi kapena ufa wopangidwa ndi alkaline cellulose ndi ethylene oxide (kapena chlorohydrin). Ma ether a cellulose osungunuka a Nonionic. Chifukwa HEC ili ndi mphamvu zabwino zokhuthala, kuyimitsa, kufalitsa, kusakaniza, kulumikiza, kupanga filimu, kuteteza chinyezi ndikupereka ma colloids oteteza, yagwiritsidwa ntchito kwambiri pakufufuza mafuta, zokutira, zomangamanga, mankhwala ndi chakudya, nsalu, kupanga mapepala ndi ma polima. Polymerization ndi madera ena. Hydroxyethyl cellulose ndi yosakhazikika pa kutentha kwabwinobwino ndi kupanikizika, kupewa chinyezi, kutentha, ndi kutentha kwakukulu, ndipo ili ndi kusungunuka kwa mchere kwabwino kwambiri kwa ma dielectric. Yankho lake lamadzi limaloledwa kukhala ndi mchere wambiri ndipo ndi lokhazikika.

Malangizo
Lowani mwachindunji mu kupanga

1. Onjezani madzi oyera mu chidebe chachikulu chokhala ndi blender yolimba kwambiri.

2. Yambani kusakaniza mosalekeza pa liwiro lotsika ndipo pang'onopang'ono sefa hydroxyethyl cellulose mu yankho mofanana.

3. Pitirizani kusakaniza mpaka tinthu tonse titanyowa.

4. Kenako onjezerani mankhwala ophera mabakiteriya, zowonjezera za alkaline monga utoto, zothandizira kufalitsa, madzi a ammonia.

5. Sakanizani mpaka hydroxyethyl cellulose yonse itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu fomula, ndipo pukutani mpaka chinthu chomalizidwa.

Yokhala ndi mowa wotsekemera

Njira iyi ndi yokonzekera kaye mowa wochuluka kwambiri, kenako nkuuwonjezera pa utoto wa latex. Ubwino wa njira iyi ndi wakuti uli ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku utoto womalizidwa, koma uyenera kusungidwa bwino. Masitepewo ndi ofanana ndi masitepe 1-4 mu njira 1, kupatula kuti kusakaniza kwambiri sikofunikira kuti usungunuke kwathunthu mu yankho lokhuthala.

Samalani
Popeza hydroxyethyl cellulose yokonzedwa pamwamba ndi ufa kapena cellulose yolimba, ndi yosavuta kuigwira ndikusungunuka m'madzi bola ngati zinthu zotsatirazi zatchulidwa.

1. Musanawonjezere hydroxyethyl cellulose komanso mutatha kuisakaniza, iyenera kusunthidwa nthawi zonse mpaka yankholo litawonekera bwino komanso loyera.

2. Iyenera kusefedwa pang'onopang'ono mu mbiya yosakaniza. Musawonjezere mwachindunji hydroxyethyl cellulose yomwe yapangidwa kukhala zipolopolo kapena mipira mu mbiya yosakaniza mochuluka kapena mwachindunji.

3. Kutentha kwa madzi ndi pH ya madzi zili ndi ubale wofunikira ndi kusungunuka kwa hydroxyethyl cellulose, kotero chisamaliro chapadera chiyenera kuperekedwa kwa izo.

4. Musawonjezere zinthu zina zamchere mu chisakanizocho musanatenthetse ufa wa hydroxyethyl cellulose ndi madzi. Kukweza PH pambuyo pa kutentha kumathandiza kuti isungunuke.

5. Momwe mungathere, onjezerani mankhwala ophera bowa mwamsanga momwe mungathere.

6. Pogwiritsa ntchito hydroxyethyl cellulose yokhala ndi kukhuthala kwakukulu, kuchuluka kwa mowa wa mayi sikuyenera kupitirira 2.5-3%, apo ayi mowa wa mayi umakhala wovuta kugwira ntchito. Hyxyethyl cellulose yomwe yakonzedwa pambuyo pake nthawi zambiri siimakhala yosavuta kupanga ziphuphu kapena ma sphere, ndipo sipanga ma colloid ozungulira osasungunuka mukawonjezera madzi.
