Ipeyinti ibonakala kuyo yonke indawo ebomini bethu, kwaye asiyiqhelanga.Mhlawumbi kwiingubo ezifundwe ebomini, zi-solvent ngakumbi okanye i-thermosetting.Nangona kunjalo, imeko yangoku yophuhliso yipeyinti ye-UV, eyipeyinti eluhlaza ehambelana nokusingqongileyo.
Ipeyinti ye-UV, eyaziwa ngokuba "yipeyinti eluhlaza ehlaziyiweyo kwaye ehambelana nokusingqongileyo kwinkulungwane yama-21", iphuhla ngesantya esiphindwe kabini ngonyaka.Ukuvela kwepeyinti ye-UV kuya kwenza ukuba umhlaba ugungqise utshintsho kwipatheni yokusetyenziswa kweengubo zendabuko.Yintoni ipeyinti yeUV?Yeyiphi impembelelo enkulu eya kuthi ukuvela kwayo ibe nayo kushishino lokwenziwa kwefenitshala?
Yintoni ipeyinti yeUV?
Ipeyinti ye-UV ibhekisa kwipeyinti ye-ultra violet yokunyanga, oko kukuthi, i-resin yokwambathisa esebenzisa i-UV njengamandla okuphilisa kunye nokuwela ngokukhawuleza kwiqondo lobushushu begumbi.Ukukhanya kwe-Ultraviolet kuveliswa ngezixhobo ezikhethekileyo, kwaye inkqubo yokuba into elayitiweyo ivelise ukusabela kweekhemikhali ngemitha yokukhanya kwe-UV kunye nokutshintsha ukusuka kulwelo ukuya kokuqinileyo kubizwa ngokuba yinkqubo yokunyanga kwe-UV.
Itekhnoloji yokunyanga i-UV yitekhnoloji yokonga amandla, ecocekileyo kunye neyokusingqongileyo.Igcina amandla - ukusetyenziswa kwayo kwamandla sisinye kwisihlanu kuphela sonyango olushushu.Ayinazinyibilikisi, inongcoliseko oluncinane kwindalo esingqongileyo, kwaye ayiyi kukhupha igesi eyityhefu kunye nekharbon diokside emoyeni.Yaziwa ngokuba yi "teknoloji eluhlaza".Itekhnoloji yokunyanga ye-UV luhlobo lwetekhnoloji ye-photoprocessing eyenza ukuba i-resin ye-epoxy acrylic yolwelo yenziwe ipolymerized ibe yimeko eqinileyo ngesantya esiphezulu yi-UV irradiation enobude obuthile.Ukusabela kokunyanga ifoto ngokusisiseko yifoto eqalwe kwipolymerization kunye nokuhlangana okuhlanganayo.Iingubo ezinyangekayo ze-UV ziye zamkelwa ngamxhelo mnye lishishini lokugquma ngenxa yobuchule obuphezulu bokunyanga ukunyanga kunye neempawu ezihambelana nokusingqongileyo.
Wazi kangakanani ngepeyinti yeUV?Ngo-1968, i-Bayer yakhokela ekusebenziseni inkqubo yokunyanga ye-UV ye-resin engaxutywanga kunye ne-benzoic acid ukuvelisa iimveliso zorhwebo, kwaye yaphuhlisa isizukulwana sokuqala se-UV yokunyanga.Ekuqaleni koo-1970, iSun Chemical Company kunye nenkampani ye-immontconciso yavelisa i-inki enyangekayo ye-UV ngokulandelelanayo.
Ekuqaleni kweminyaka yoo-1980, abavelisi bemigangatho baseTaiwan baqala ukutyala imali kunye nokwakha iifektri kumhlaba omkhulu, kwaye kwaqaliswa ukusetyenziswa kwe-uvpaint kunye neteknoloji yemveliso.Phambi kweminyaka yoo-1990s, ii-uvcoatings zazisetyenziselwa ikakhulu uqalo kunye nokusetyenzwa komgangatho wamaplanga kunye nokupolisha kwesigqubuthelo seplastiki, kwaye zazibonakala elubala.
Kwiminyaka yakutshanje, kunye nokucutshungulwa okukhulu kwefenitshala yasekhaya, i-uvpaint iye yangena ngokuthe ngcembe kwintsimi yengubo yokhuni, kwaye izibonelelo zayo ziye zaqatshelwa ngokubanzi.Okwangoku, i-uvpaint isetyenziswe ngokubanzi kwiphepha, iplastiki, isinyithi, iglasi, i-ceramics kunye nezinye iindawo, kwaye iphuhlisa kwicala lokusebenza.
Ithemba lemarike yeengubo ze-UV
Ipeyinti ye-UV, ungakanani owaziyo malunga neengubo zemveli ezisetyenziswa kwishishini lefenitshala yasekhaya okwangoku iseyiPu, PE kunye neNC.Ngokwakhiwa kokutshiza, ukusebenza kakuhle kuphantsi, kwaye kunzima ukuqesha abasebenzi kwaye iindleko zomsebenzi ziphezulu.Kuphela ngokuphucula inqanaba lemveliso ezenzekelayo yokwenziwa kwefenitshala yamashishini anokophula umqobo wophuhliso kunye nokuphucula ukusebenza kakuhle kweshishini.Kwelinye icala, iVOC ekhutshwa ziifektri zefenitshala zisebenzisa iingubo zemveli ibe ngumthombo obalulekileyo wokungcoliseka kwendalo.Okwangoku, uqoqosho lwekhabhoni ephantsi kunye nokusetyenziswa okuluhlaza kuyathandwa, okuya kuvelisa imigangatho emitsha yobugcisa kunye nemiqobo yorhwebo.Amazwe aphuhlileyo afana neYurophu kunye neMelika aqulunqe kwaye akhupha inani lamanyathelo okulawula ukuvuselela ishishini lefenitshala ukuba liphuhlisele ekukhuseleni uhlaza kunye nokusingqongileyo.Abavelisi befenitshala yasekhaya, ngakumbi amashishini ajolise ekuthengiseni ngaphandle, ajongene nemingeni ekuphela kwayo ngaphambili.
Ngaphantsi kwemvelaphi yophuhliso loshishino, i-uvcoatings ihambelana nesiqhelo samaxesha kwaye ibe yinto entsha ekuphuhliseni i-coating yefenitshala.Izinto eziluncedo zayo njengokusingqongileyo nokugcina umbane kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo zivela ngokuthe ngcembe, nto leyo ethe yatsala ingqalelo yamasebe esizwe afanelekileyo.ISicwangciso seMinyaka emiHlanu se-11 sophuhliso lweshishini lokugquma kunye nesicwangciso sophuhliso lwexesha eliphakathi nelide lenzululwazi kunye nethekhnoloji yeshishini lokugquma libeka ngokucacileyo imfuneko yokuphuhlisa ngamandla i-UV ehambelana nokusingqongileyo.Ipeyinti ye-UV sele iza kuphuma okokuqala kushishino, kwaye ithemba lemarike alinakulinganiswa.
