Khulisa i-hydrophilicity yezinto zokuphulukisa ze-UV

Izembatho ezilaphekayo ze-UV zinezinzuzo zejubane lokuphulukisa ngokushesha, ubungane bemvelo, ukonga amandla, izindleko eziphansi, njll.Ngokuvamile, inhlaka ye-photosensitive liquid resin ingaguqulwa ngokuqondile ibe inhlaka ephulukisiwe ngokuyibeka ngaphansi kwesibani se-UV ekushiseni komoya Ngokujwayelekile, ayinazo izinto eziphilayo ezishintshashintshayo zosuku olulodwa.Ngokunakwa okubhekiswe ezindabeni zemvelo, ucwaningo, ukuthuthukiswa kanye nokusetshenziswa kwale nqubo “eluhlaza” evumelana nemvelo kuya ngokuya kujula futhi kudume.I-Hydrophilic coating iwuhlobo lwe-coating esebenzayo ethuthukiswe ngokushesha eminyakeni yamuva Isetshenziswa kakhulu emikhiqizweni ye-aluminium ne-aluminium alloy, njengama-aluminium fins of air conditioning heat exchanger.I-hydrophilic coating yendabuko ngokuvamile yenziwa ngokubhaka i-hydrophilic resin ku-200C amashumi amasekhondi, bese iphulukisa futhi ixhumanise ukwenza ifilimu.Nakuba indlela yokulungiselela inobuchwepheshe obuvuthiwe kanye ne-hydrophilicity enhle, idla amandla amakhulu, ishintshanisa izincibilikisi zemvelo futhi inendawo yokwakha engeyinhle.Ukulungiswa kwezingubo ezihlanzekile ze-organic hydrophilic ngokuphulukiswa kwe-UV nokuxhumanisa akukwazi nje ukusizakala ngezinzuzo zokwelashwa kwe-UV, kodwa futhi kuhlangabezane nezidingo ze-hydrophilicity.Kuleli phepha, kwamukelwa umqondo omusha wokuhlanganisa.Ngokusekelwe ku-acrylate copolymer enesisindo esiphansi, kwethulwa i-photosensitive monomer, kwase kwakhiwa ifilimu exhumene nesithombe ephothiweyo ukuze kulungiswe izimbotshana ze-hydrophilic.Imiphumela yokwethulwa kwe-GMA, isilinganiso se-monomer, uhlobo lwe-diluent esebenzayo kanye nokuqukethwe ku-hydrophilicity nokumelana namanzi kwezingubo zaphenywa.

Izinto ezilaphekayo ze-UV ngokuvamile ziyi-hydrophobic, ehlobene eduze nokwakheka kokwakheka kwazo.Ama-Photoinitiators kufanele asetshenziswe kufomula yokwelapha ye-UV.Ngezinye izikhathi, ukuze kwandiswe ukuphulukiswa kwendawo, ezinye izithasiselo ezikhuthaza ukuphulukiswa kwendawo zizokwengezwa.Lawa ma-photoinitiators kanye nezithasiselo ngokuvamile ane-hydrophobic, futhi imikhiqizo yokubola yama-photoinitiators izothuthela phezulu kwento elaphayo, ngaleyo ndlela iqinise i-hydrophobicity yezinto zokuphulukisa ze-UV.I-resin kanye ne-monomer kufomula yokwelapha ye-UV nazo ngokuyisisekelo ziyi-hydrophobic ngokwemvelo, futhi i-engeli yokuxhumana ngokuvamile iphakathi kuka-50 no-90 degrees.

I-styrene sulfonate, i-polyethylene glycol acrylate, i-acrylic acid nezinye izinto ziyi-hydrophilic ngokwazo, kodwa uma zisetshenziswa ezintweni zokuphulukisa ze-UV, i-hydrophilicity yezinto eziphulukisiwe ngeke inyuke kakhulu, futhi i-engeli yokuxhumana ngokuvamile izohlala ingaphezu kwama-degree angu-50.

I-Hydrophilicity isho ukuthi ama-molecule noma ama-molecular aggregate kulula ukumunca amanzi noma angancibilika ngamanzi.Ubuso bezinto eziqinile ezakhiwe ama- molecule anjalo bumanziswa kalula ngamanzi.Ukusetshenziswa kwezingubo eziningi zokumboza kudinga indawo ebonakalayo ukuthi ibe ne-hydrophilicity enhle ngokwanele, njengefilimu, ukuphrinta kwe-offset, izinamathiselo ezikhethekile, izinto ezihambelana ne-biocompatible, njll. Ezisetshenziswa ezingokoqobo, i-hydrophilicity ivamise ukukalwa nge-engeli yokuxhumana yamanzi endaweni ebonakalayo etholiwe. nge-engeli mitha.Izinto ezinama-engeli okuxhumana angaphansi kwamadigri angu-30 ngokuvamile zibhekwa njenge-hydrophilic.
