Kordhi hydrophilicity ee alaabta daweynta UV

Dahaarka UV ee la daweyn karo waxay leeyihiin faa'iidooyinka xawaaraha daaweynta degdega ah, saaxiibtinimo deegaanka, badbaadinta tamarta, kharash yar, iwm.Guud ahaan, xabagta dareeraha ah ee sawir-qaadista waxa si toos ah loogu beddeli karaa resin la daweeyay iyada oo la hoos geliyo laambad UV heerkulka hawada Guud ahaan, kuma jiraan xeryahooda organic kacsan hal maalin.Iyadoo fiiro gaar ah loo leeyahay arrimaha deegaanka, cilmi-baarista, horumarinta iyo adeegsiga habkan "cagaaran" ee deegaanka-saaxiibtinimo ayaa noqonaya mid aad u qoto dheer oo caan ah.daahan Hydrophilic waa nooc ka mid ah daahan functional horumariyo si degdeg ah sannadihii la soo dhaafay Waxaa inta badan waxaa loo isticmaalaa in aluminium iyo aluminium aluminium alaabta, sida baalal aluminium ee qaboojiyaha kulaylka.Daahan dhaqameedka hydrophilic waxaa badanaa lagu sameeyaa iyada oo la dubayo resin hydrophilic at 200C tobanaan ilbiriqsi, ka dibna daawaynaya oo iskutallaabta si loo sameeyo filim.Inkasta oo habka diyaarinta uu leeyahay tignoolajiyada qaan-gaadhka ah iyo biyo-dhismeed wanaagsan, waxay isticmaashaa tamar badan, waxay kordhisaa dareerayaasha organic-ga ah waxayna leedahay jawi dhisme oo liita.Diyaarinta dahaarka dabiiciga ah ee saafiga ah ee daaweynta UV iyo isku-xirnaanta ma aha oo kaliya inay ka faa'iidaystaan ​​faa'iidooyinka daaweynta UV, laakiin sidoo kale waxay buuxinayaan shuruudaha hydrophilicity.Warqadan, fikrad cusub ayaa la qaatay.Iyada oo ku saleysan miisaanka unugyadu yar yahay ee acrylate copolymer, monomer sawir-qaade ayaa la soo bandhigay, ka dibna filim iskutallaab ah oo la sawiri karo ayaa la sameeyay si loo diyaariyo daahan hydrophilic.Saamaynta hordhaca ah ee GMA, saamiga monomer, nooca firfircoon ee firfircoon iyo nuxurka hydrophilicity iyo caabbinta biyaha ee dahaarka ayaa la baaray.

Alaabta daawaynta UV sida caadiga ah waa hydrophobic, kaas oo si dhow ula xiriira ka kooban ee ay qaabaysan.Photoinitiators waa in lagu isticmaalo qaacidada daaweynta UV.Mararka qaarkood, si kor loogu qaado daaweynta dusha sare, qaar ka mid ah waxyaabaha lagu daro si kor loogu qaado daaweynta dusha sare ayaa lagu dari doonaa.Sawir-qaadayaashan iyo waxyaabaha lagu daro inta badan waa hydrophobic, iyo alaabada burburka ee sawir-qaadayaasha waxay u haajiri doonaan dusha sare ee alaabta daweynta, sidaas darteed xoojinta hydrophobicity ee alaabta daaweynta UV.Xabagta iyo monomer-ka ku jira qaacidada daaweynta UV sidoo kale asal ahaan waa hydrophobic dabeecadda, iyo xagasha xiriirku inta badan waa inta u dhaxaysa 50 iyo 90 darajo.

Styrene sulfonate, polyetylen glycol acrylate, acrylic acid iyo walxaha kale waa hydrophilic laftooda, laakiin marka loo isticmaalo qalabka daaweynta UV, hydrophilicity ee alaabta la daaweeyay si weyn looma kordhin doono, xagasha xiriirka guud ahaan waxay ahaan doontaa in ka badan 50 darajo.

Hydrophilicity macnaheedu waa in unugyadu ama isku-darka molecular ay fududahay in la nuugo biyaha ama lagu milmi karo biyo.Dusha sare ee maaddooyinka adag ee ay sameeyeen molecules noocan oo kale ah ayaa si fudud u qoysay biyaha.Codsiga dahaarka badan waxay u baahan tahay dusha maaddada si ay u lahaato biyo ku filan oo wanaagsan, sida filimka, daabacaadda daabacaadda, dhejisyada gaarka ah, qalabka biocompatible, iwm oo leh mitir xagal.Alaabta xaglaha xidhiidhka ka yar 30 digrii ayaa guud ahaan loo tixgaliyaa biyo-saar.
