Iingubo ezinyangekayo ze-UV zineengenelo zesantya sokunyanga ngokukhawuleza, ubuhlobo bokusingqongileyo, ukonga amandla, ixabiso eliphantsi, njl. ", kwaye zisetyenziswa kakhulu kwiphepha, irabha, iplastiki kunye nezinye iindawo zokugquma.Ngokubanzi, i-photosensitive liquid resin inokuguqulwa ngokuthe ngqo ibe yiresin enyangisiweyo ngokuyibeka phantsi kwesibane se-UV kwiqondo lobushushu lomoya Ngokubanzi, ayiqulathanga iikhompawundi eziphilayo eziguquguqukayo zosuku olunye.Ngokuqwalaselwa kwimiba yokusingqongileyo, uphando, uphuhliso kunye nokusetyenziswa kwale nkqubo "eluhlaza" ehambelana nokusingqongileyo iya iba yinto enzulu kwaye ithandwa.I-Hydrophilic coating luhlobo lwe-coating esebenzayo ephuhliswe ngokukhawuleza kwiminyaka yamuva Isetyenziswa kakhulu kwi-aluminium kunye neemveliso ze-aluminium alloy, ezifana ne-aluminium fins ye-air conditioning exchanger heat exchanger.Ukutya okuqhelekileyo kwe-hydrophilic ngokuqhelekileyo kwenziwa ngokubhaka i-resin ye-hydrophilic kwi-200C yamashumi emizuzwana, emva koko ukunyanga kunye nokudibanisa ukwenza ifilimu.Nangona indlela yokulungiselela inetekhnoloji evuthiweyo kunye ne-hydrophilicity elungileyo, isebenzisa amandla amakhulu, iguqula izinyibilikisi zendalo kwaye inemeko engalunganga yokwakha.Ukulungiswa kwezinto ezicocekileyo ze-organic hydrophilic coatings ngokunyangwa kwe-UV kunye ne-cross-linking ayinakuthatha kuphela inzuzo ye-UV yokunyanga, kodwa ihlangabezana neemfuno ze-hydrophilicity.Kweli phepha, kwamkelwa ingcamango entsha yokudibanisa.Ngokusekwe kubunzima bemolekyuli ephantsi ye-acrylate copolymer, i-photosensitive monomer yaziswa, kwaye emva koko ifilimu edibeneyo edibeneyo yokufota yaqulunqwa ukulungiselela iingubo ze-hydrophilic.Iziphumo zokuqaliswa kwe-GMA, umlinganiselo we-monomer, uhlobo olusebenzayo lwe-diluent kunye nomxholo kwi-hydrophilicity kunye nokuchasana kwamanzi kweengubo zaphandwa.
Izinto ezinyangekayo ze-UV zidla ngokuba yi-hydrophobic, ehambelana ngokusondeleyo nokubunjwa kweendlela zazo.Iifotonitiators kufuneka zisetyenziswe kwifomula yokunyanga ye-UV.Ngamanye amaxesha, ukuze kwandiswe ukunyanga komphezulu, ezinye izongezo zokukhuthaza ukunyangwa komphezulu ziyakongezwa.Ezi photoinitiators kunye nezongezo zihlala ziyi-hydrophobic, kwaye iimveliso zokubola kweefotonitiators ziya kufudukela kumphezulu wezinto zokunyanga, ngaloo ndlela zomeleza i-hydrophobicity yezinto zokunyanga ze-UV.I-resin kunye ne-monomer kwifomula yokunyanga ye-UV nazo ziyi-hydrophobic kwindalo, kwaye i-angle yoqhagamshelwano ihlala iphakathi kwama-50 kunye nama-90 degrees.
I-Styrene sulfonate, i-polyethylene glycol acrylate, i-acrylic acid kunye nezinye izinto ziyi-hydrophilic ngokwazo, kodwa xa zisetyenziselwa izinto zokunyanga ze-UV, i-hydrophilicity yezinto eziphilisiweyo ayiyi kunyuswa kakhulu, kwaye i-angle yoqhagamshelwano iya kuhlala ingaphezulu kwama-50 degrees.
I-Hydrophilicity ithetha ukuba iimolekyuli okanye i-molecular aggregates kulula ukufunxa amanzi okanye inokunyibilika ngamanzi.Umphezulu wezinto eziqinileyo ezenziwe zezo molekyuli zimanziswa ngokulula ngamanzi.Ukusetyenziswa kweengubo ezininzi zokugquma kufuna umphezulu wezinto eziphathekayo ukuba ube ne-hydrophilicity efanelekileyo ngokwaneleyo, njengefilimu, ukuprintwa kwe-offset, i-adhesives ekhethekileyo, izinto ezihambelana ne-biocompatible, njl. Kwizicelo eziphathekayo, i-hydrophilicity idla ngokulinganiswa nge-angle yokudibanisa yamanzi kwindawo efunyenweyo. ngemitha ye-engile.Izinto eziphathekayo ezinama-angles angaphantsi kwama-30 degrees zibhekwa njenge-hydrophilic.
