Ultrasonic Paraffin Wax Nanoemulsion

Indlela yokulungisa u-Emadsion we-Paraffin Wax
I-nano-sized wax emulsion yakhiwa kusuka ku-wax encibilikisiwe we-wax (njengesigaba samafutha), amanzi agcobhoziwe, ne-anionic SDS njenge-survivant. Ukuze wakhe umxube wangaphambi kwenhlanganisela, i-wax, amanzi kanye ne-survivant kwenziwa nge-homogenised kusetshenziswa isishukumisi sikazibuthe ngo-1000 rpm. Ngakho-ke, i-surfactant (okuhlushwa i-10 mg / ml ye-emulsion) namanzi kuxutshwe ku-beaker kanye nokushisa ukushisa ukuze kuvume. 65-70ºC. Ngemuva kwalokho, i-paraffin wax iyengezelwa ngokugcina ingxenyeni yevolumu engu-0,5 kawoyela ophansi ngaphansi kogqozi lukazibuthe.
Ngemuva kokungezwa okuphelele kwe-paraxine, umxube ohlanganisiwe oxubene nawo uhanjiswa nge-ultrasonic bench-top homogenizer I-UIP1000hdT (1000W, 20kHz) ye-approx. 15 iminithi. Inqubo ye-ultrasonic emulsification iholela ku-nano waxemulsion ngokuzinza kakhulu.

Ama-surfactants

Ama-emulsions we-Wax angagcinwa yi-mechanical steric (esebenzisa ama-emulsifiers ama-nonionic) noma nge-electrostatic mechanism (usebenzisa i-ionic emulsifiers, ngokuvamile e-anionics). Ukuhlanganisa ama-emulsifiers anionic nonionic kunikeza imulsion ukuzinza okukhulu ngoba izinhlayiya ze-wax zivikelwe kuzo zonke izindlela zokuzinza. Lokhu kubizwa njengendlela yokuzinza kwe-electro-static.
Ukuze kusetshenziswe ama-waxes, ama-emulsifiers ahlukene noma ama-surfactants, angaba anionic, cationic noma angewona ionic, angasetshenziswa. Ama-surfactant asetshenziswe kakhulu ayenamafutha e-alcohol ethoxylates njengama-surfactants angewona ama-ionic ngoba anikeza ukuzinza okungavamile kwamanzi aqinile, ama-pH-shocks nama-electrolyte. Ngezinye izici ezithile ezibonakalayo, ezinye izinto ezihlukahlukene zisetshenzisiwe, isib. Ama-surfactants e-anionic for hydrophobicity angcono noma abasebenza cationic for adhesion kangcono.
Qaphela: Amancane amaconsi, i-surfactant edingekayo ukuze ihlanganise ubuso be-droplet kusukela isilinganiso se-V / S sesigaba silandelayo: S / V = ​​3 / R. Noma yimuphi ukwanda, x * l noma x * r ubude noma irejista, ukwanda kwendawo yendawo x x squared (x2) futhi ukwanda kwevolumu x kubhekwe (x3).

Ukuqamba nge-Emxsion Emulsions kanye ne-Dispersions

I-homogenizers ye-Ultrasonic ayisebenziswanga kuphela ukwenza ama-emulsions we-wax / ama-dispersions – zisetshenziselwa ukucubungula ukuxhuma kwe-wax ngezinyathelo ezengeziwe zokufaka imulsion njengendlela yokwengeza kumkhiqizo wokugcina (isib. ukugqoka, i-lacers, amapende, izimonyo njll).

Amaqiniso Okufanele Ukwazi

I-Wax

Ama-wax achazwa njengengxenye ehlukahlukene yamakhemikhali e-hydrophobic, amamoza okulimala kalula eduze kwamazinga okushisa aseduze. Ama-wax aqalwa kusuka kwizakhi ezahlukahlukene kufaka phakathi ama-hydrocarbons (ama-alkanes ajwayelekile noma ahlutshiwe kanye nama-alkenes), ama-ketones, ama-diketones, i-alcohols eyinhloko neyesibili, i-aldehydes, i-sterol esters, i-alkanoic acid, i-terpenes (squalene) kanye nama-monoesters (ama-esters we-wax). Ukwakheka kwamakhemikhali ka-waxes kuyinkimbinkimbi futhi kuyehluka, kodwa ngama-wax amaningi ajwayelekile aqukethe ingxenye ephezulu kakhulu yama-alkanes futhi ama-hydrocarbons anama-athomu wekhabhoni amade noma amade kakhulu (kusuka kuma-athomu ayi-12 kuye kwangaba ngu-38). Ziqinile ebangeni elikhulu lokushisa (iphuzu le-fusion phakathi kuka-60 ° C no-100 ° C). Lapho encibilikisiwe, aphenduka abe uketshezi olunamanzi amancane.
Zibonakaliswa ukungabikho komzimba emanzini kodwa ukutholakala kwamanzi ezinhlakeni eziphilayo, ezingenayo i-solvents. Imifino ingahlukaniswa ngokwemvelo (isitshalo-, isilwane esitholwe), ama-semi-synthetic and synthetic waxes.
Ukukhiqizwa kwezimakethe ze-waxes, amafutha angcolile ngumthombo oyinhloko.

Izinhlobo ezimbili ezibaluleke kakhulu ze-petroleum wax ziyi-parafini ne-microcrystalline wax:
I-paraffin wax ikakhulukazi iqukethe ukuhambisana okuqinile okumhlophe, okungenasiphelo, okungenangqondo, okungenasiphelo, okungafani, okuphakathi kwamanzi angu-46 ° C no-68 ° C (115 ° F no-154 ° F), kanye nobukhulu be-approx. 900 kg / m3. It is a macrocrystalline isakhiwo futhi engenawo amanzi, kodwa ehlanganisiwe e-ether, benzene, kanye esters ezithile. I-paraffin waxes ivela emafutheni angcolile futhi iqukethe ama-athomu angu-20 no-40 e-carbon.
I-microcrystalline wax, eyaziwa nangokuthi i-petrolatum, isetshenziselwa izinhlelo zokusebenza eziningi ngenxa yephunga layo, umbala, okuqukethwe kukawoyela, impahla yokuhambisana nokuhambisana namafutha.

ama-a-olefin wax zakhiwa ngokuzenzakalelayo ku-ethylene nge-Fischer-Tropsch synthesis ne-catalyst ye-Ziegler-Natta noma nge-oligomerization ye-ethylene. I-Alpha-olefin yaxes isetshenziselwa kakhulu izithasiselo zamafutha, amafutha we-PVC, amakhandlela, amakhemikhali okugcoba amafutha kanye nezimonyo.

I-Polyethylene Wax (PE-WAX) yi-polyethylene yesisindo esincane se-ultra (ULMWPE) esakhiwa ngamaketanga e-ethylene monomer. I-polypropylene wax (I-PP-WAX) iyinhlayiya yamakhemikhali ephansi yama-crystalline.
Kokubili, i-olyethylene ne-polypropylene waxes yimizimba yabantu futhi isetshenziselwa ukwakha ama-plastiki.

Ama-waxes e-Copolymer ezifana ne-ethylene vinyl acetate (EVA) ne-ethylene acrylic acid (EAA) isakazeka kakhulu ekubunjweni kokugqoka, isib. ama-basecoats ensimbi.

Imifino kanye nezithasiselo ze-wax zisetshenziselwa ukuboleka ukugcoba / ukukhishwa komkhiqizo, ukuphikisana, ukumelana nokuvimbela, ukuvimbela / ukuvimbela, ukupholisa noma ukulinganisa, ukumelana nokuphikisana nokusiketshezi kanye / noma ukumelana kwamanzi.
Imifucumfucu iyisakhi esetshenziswa kabanzi emaqenjini amaningi, njengokukhiqiza amakhemikhali (isib. Okuhle & i-chemical chemistry), ukumbozwa, amapende & ama-inks, izithasiselo & ama-modifiers, ama-adhesives, ama-plastiki & I-PVC, amathayi & ama-rubber, ukwakhiwa & ukwakha, amadivayisi wokulawula ama-thermostatic, amaphakheji, ukudla, nezimonyo.

I-Waxes yemvelo:

  • I-Waxes yezilwane: i-bex, i-lanolin, i-tallow, i-shellac, i-spermaceti
  • Imifino yemifino: carnauba, candelilla, soy, castor, irayisi bran, bayberry, jojoba njll.

Imikhumbi yamaminerali:

  • Imithombo Yamafutha: Ceresin, i-Montan, i-Ozocerite, i-Peat Wax
  • I-Petroleum Waxes: i-parafini, ama-wax microcrystalline, isib. Petrolatum

Ama-Wax asebenzayo:
Ama-Wax Synthetic: i-ethylenic polymers isib polyethylene & i-polyol ether-esters; i-polyolefin wax; amafutha e-fatty acid amide; ama-naphthalenes aneklorini; uhlobo lwe-hydrocarbon, isib. Fischer-Tropsch

i-wax emulsion

I-wax emulsion / wax ukusabalalisa iyinhlanganisela enzile yomsele owodwa noma amaningana emanzini. Njengoba ama-waxes nama-aqueous liquids ngokuvamile engabonakali, ama-surfactants kanye nenqubo yokuxuba eyinkimbinkimbi, isib. Amandla e-ultrasound, adingekayo ukuze enze umshini omile omile. Ngamagama alungile, i-emulsion ye-wax kufanele ibizwe ngokuthi i-wax dispersion njengoba ama-wax eqinile ekamelweni lokushisa. Kodwa njengoba ama-emulsions we-wax / ama-dispersions alungiswa ngama-waxes aqoshiwe, imigomo “emulsification” futhi “i-wax emulsion” zivame ukusetshenziselwa ukwakheka kwe-waxous, ngenkathi leli gama “ukuhlakazeka kwe-wax” ikakhulukazi ichaza ukubunjwa kwe-wax okusungulwe.

Emulsion

I-emulsion yiketshezi ekuhlakazeni oketshezi oketshezi kabili noma okungaphezulu kokungabonakali.
I-emulsion ingenzeka ngezinhlobo ezihlukahlukene: w / o, o / w, w / o / w, o / w / o
Uhlobo lwe-emulsion (i-w / o noma i-o / w) lingabuyekezwa ngokuhlolwa kwe-dilution. I-emulsion ingahle ihlanjululwe ngesigaba esilandelayo / sangaphandle. Enye indlela yokubona uhlobo lwe-emulsion yi-test testing. I-ionic o / w emulsions ayihambisani, kanti i-o / w emulsions iqhuba okwamanje kagesi.
Ukusetshenziswa kweCoCl2 ukuhlolwa kwephepha lokuhlunga, iphepha lokuhlunga lihlanganiswe ne-CoCl2 futhi omisiwe (umbala ohlaza okwesibhakabhaka). Umbala weCoCl2 iphepha lokuhlunga liphenduka i-pink uma i-o / w emulsion ingeziwe.
