I-HYDROXYTYL ILANDILONE (Hec)Ngaba i-selsucle inyibilikisi ye-Isuple i-Ertulose, esetyenziswa ngokubanzi kwi-cayishini, izinto zokwakha, amayeza, iichemicals zemihla ngemihla kunye nezinye izinto. Nangona kunjalo, i-HEC ine-solional ephezulu kunye nobuthathaka hydrophobizetion, onokukhokelela kwimida yokusebenza kwezinye iimeko zesicelo. Ke ngoko, nge-hydrocketyl ye-hydrophothyl i-hydroxyyl sellyulose (HMHIC) yeza ekuphuculeni iipropathi zayo ze-propelogical, amandla okuqina, uzinzo lwezinto ezizinzileyo kunye nokuxhathisa kwamanzi.
1. Ukubaluleka kokulungiswa kwe-hydrophobic ye-hydroxyythl seluplose
Ukuphucula iipropathi ezinkulu kunye neepropathi zeRheOology
Utshintsho lweHydrophobic lunokuphucula kakhulu ubuchule bokuthathwa kwe-hec, ngakumbi ngamaxabiso asezantsi asezantsi. Ibonisa i-viscofity ephezulu, enceda ekuphuculeni i-Thseotropy kunye nePseudoplastity yenkqubo. Le mpahla ibaluleke ngokukodwa kwicandelo lemali, i-oyile yeoyile yokuqhuba, iimveliso zononophelo lobuqu, njl., Kwaye zinokuphucula uzinzo kunye nokusetyenziswa kwemveliso.
Ukuphucula ukuzinza kwe-emulsion
Kuba i-HAP yokuguqulwa inokwenza isakhiwo esidibeneyo kwisisombululo samanzi, iphucula kakhulu uzinzo lwe-emulsion, inokunciphisa ukwahlulwa kwamanzi ioyile, kunye nokuphucula isikhokelo semogaqo. Ke ngoko, inexabiso elikhulu lemisebenzi kwimisebenzi yemitya yokunxiba, iimveliso zonyango kunye nee-enulsifiers zokutya.
Ukuphucula ukuxhathisa kwamanzi kunye neempawu zokwenza ifilimu
I-hec yemveli i-hydrophilic kwaye inyibilika ngokulula kwiindawo eziphakamileyo zokufuma okanye amanzi, ezichaphazela ukumelana kwamanzi kwezinto. Ngokulungiswa kwe-hydrophobic, isicelo sayo kwi-cares, imihlambi, ukungcungcutheka kunye namanye amasimi kunokuphuculwa, kwaye ukumelana kwamanzi kunye neempawu zokwenza ifilimu zinokuphuculwa.
Phucula iipropathi zeShear
I-HOCDROphobic-iguqulwe i-HYDROphobic inokuphuhlisa i-viscofity phantsi kweemeko eziphezulu ze-Shear, ngelixa igcina ukungangqinelani kumaxabiso asezantsi asezantsi, ngaloo ndlela ukuphuculwa kokusetyenziswa kwamandla. Inexabiso elibalulekileyo kumashishini anje ngembiya ye-oyile kunye nemveliso yoyilo.
I-2. Ukulungiswa kwe-hydrophobic ye-hydroxyythl seluplose
Ukulungiswa kwe-hec hydrophobic kuhlala kufezekiswa ngokwazisa amaqela e-hydrophobic ukuhlengahlengisa amandla ayo kunye neepropathi ezinkulu ngokulandelelana kwamachiza okanye ukuguqulwa komzimba. Iindlela zokulungiswa kwe-hydrophobic zezi zilandelayo:
Ukumiswa kweqela le-hydrophobic
Ukwazisa i-Alkyl (njenge-hexadecyl), i-Aryl (efana ne-phenyl), i-siloxane okanye amaqela acocekileyo kwimolekyuli ye-hec ngokuphucula i-hydrophole. Umzekelo:
Sebenzisa i-Estestation okanye i-etheristic yokuphendula kwiGraft-Chain Alkyl, njenge-hexadedyl okanye i-octyl, ukwenza isakhiwo sokudibanisa i-hydrophobic.
Ukwazisa amaqela esilika nge-seloxane uhlengahlengiso lokuphucula ukunganyangeki kwamanzi kunye ne-phulity.
Sebenzisa uguquko lokuphucula ukumelana kwemozulu kunye ne-hydrophobiction, eyenza ilungele iingubo eziphezulu okanye izicelo ezizodwa zokusingqongileyo.
I-copolymerization okanye i-colling yokudibanisa
Ngokwazisa ii-conononomers (ezinjengee-acrylates) okanye iiarhente ezinqamlezileyo (ezinje nge-Epoxy Retins) ukwenza inethiwekhi edibanisayo, ukunganyangeki kwamanzi kunye nokuthathwa kwe-hec kuphucuka. Umzekelo, usebenzisa i-HAC eguqulwe nge-Hydrophobiod kwi-Polymer Emulssions inokuphucula isiphumo sozinzo kunye nobumdaka boku-emulsion.
Ukuguqulwa komzimba
Ukusebenzisa i-adsorption okanye itekhnoloji yokuthobela, iimolekyuli ze-hydrophobic zidityaniswe kumphezulu we-hec ukwenza i-hydrophobicity ethile. Le ndlela inobulali kwaye ilungele izicelo ezineemfuno eziphezulu zokuzinza kwamachiza, njengokutya kunye namayeza.
Ukulungiswa kombutho we-hydrophobic
Ngokwazisa ngesixa esincinci samaqela e-hydrophobic kwimolekyuli ye-hec, yenza i-aggregate yomlinganiso kwisisombululo esinamandla, ngaloo ndlela siphucula amandla amnandi. Le ndlela isetyenziswa ngokubanzi kuphuhliso lwamanzi okusebenza aphezulu kwaye ilungele iingubo, iikhemikhali zeoyile kunye nezinye amasimi.
Utshintsho lwe-hydrophobic yehydroxyyl seluploseYindlela ebalulekileyo yokuphucula ukusebenza kwawo isicelo, enokuphucula ubuchule bayo bokuthathwa, ukuzinza komhlaba, ukunganyangeki kwamanzi kunye neepropathi ze-ripoolog. Iindlela zokulungiswa eziqhelekileyo zibandakanya ukumiswa kweqela le-hydrophobic, i-copolymerization okanye ukuguqulwa ngokudibeneyo, ukuguqulwa komzimba kunye nokulungiswa kwe-hydrophobic yombutho. Ukukhetha okuqinisekileyo kweendlela zokulungiswa kungazenzela ukusebenza kwe-IC ngokweemfuno ezahlukeneyo zokusetyenziswa, ukuze kudlale indima enkulu kwimimandla emininzi enjengeekheyili zeoyile, ukhathalelo lobuqu, kunye namayeza.
