Nekuwedzera kutarisisa kwemhinduro dzakasimba mumakore achangopfuura, tinoona kudiwa kuri kukura kwezvivharo zvekuvaka zvakatsiga uye masisitimu akavakirwa pamvura, kusiyana nezvinonyungudutsa. UV kurapa inyanzvi inoshanda tekinoroji yakagadzirwa makumi emakore apfuura. Nekubatanidza mabhenefiti ekurapa nekukurumidza, emhando yepamusoro UV kurapa nehunyanzvi hwemvura yakavakirwa masisitimu, zvinokwanisika kuwana akanakisa epasirese maviri akasimba.
Kuwedzera tekinoroji kutarisisa pakusimudzira kwakasimba
Iko kusimukira kusati kwamboitika kwedenda muna 2020, kuchinja zvakanyanya mararamiro atinoita nekuita bhizinesi, kwakakonzerawo kutarisa kwezvipo zvinogara mukati meindasitiri yemakemikari. Zvisungo zvitsva zvinoitwa padanho repamusoro rezvematongerwo enyika pamakondinendi akati wandei, mabhizinesi anomanikidzwa kuongorora maitiro avo uye zvisungo zvekusimudzira zvinoongororwa kusvika kune ruzivo. Uye iri mune ruzivo mhinduro dzinogona kuwanikwa kune kuti matekinoroji anogona kubatsira sei kuzadzisa zvinodiwa nevanhu nemabhizinesi nenzira yakagadzikana. Mashandisirwo etekinoroji anogona kushandiswa uye kusanganiswa munzira nyowani, semuenzaniso musanganiswa weUV tekinoroji uye masisitimu emvura.
Environmental push yeUV yekurapa tekinoroji
UV yekurapa tekinoroji yakagadziridzwa kare muma1960 ichishandisa makemikari ane unsaturations kurapa nekuratidzwa kune UV mwenje kana Electron Beams (EB). Yakabatana inonzi kurapa kwemwaranzi, mukana wakakura waive wekurapa nekukasira uye yakanakisa yekuvhara zvivakwa. Munguva ye80s tekinoroji yakagadziridzwa uye yakatanga kushandiswa pachiyero chekutengesa. Sezvo kuziva kwezvinonyungudutsa zvakatipoteredza kwakawedzera, ndizvo zvakaitawo mukurumbira wekurapa nemwaranzi senzira yekudzikisa huwandu hwezvinonyungudutsa zvinoshandiswa. Maitiro aya haana kudzikira uye kuwedzera kwekugamuchirwa uye mhando yezvikumbiro kwaenderera mberi kubva ipapo, uye ndizvo zvakaitawo kudiwa kwese maererano nekuita uye kusimba.
Kusimuka kubva kune zvinonyungudutsa
Kunyangwe UV kuzvirapa pachayo yatove tekinoroji yakasimba, mamwe maapplication achiri kuda kushandiswa kwezvinonyungudutsa kana monomers (nenjodzi yekutama) kudzikisa viscosity yemhedzisiro inogutsa kana uchiisa coating kana inki. Munguva pfupi yapfuura, iyo pfungwa yakabuda yekubatanidza UV tekinoroji neimwe yakagadzikana tekinoroji: mvura yakavakirwa masisitimu. Aya masisitimu anowanzo angave emhando inonyungudika yemvura (zvichida kuburikidza neiyo ionic dissociation kana miscible kuenderana nemvura) kana yePUD (polyurethane dispersion) mhando apo madonhwe echikamu chisiri-miscible anoparadzirwa mumvura kuburikidza nekushandiswa kweanoparadzira.
Kupfuura kupfekedzwa kwehuni
Pakutanga iyo yakavharwa nemvura yeUV coatings yakanyanya kutorwa neindasitiri yehuni yekuputira. Apa zvaive nyore kuona zvakanakira kusanganisa mabhenefiti kubva kune yakakwira chiyero chekugadzira (ichienzaniswa neisiri-UV) uye yakakwira makemikari kuramba neVOC yakaderera. Essential properties mune coatings for flooring and furniture. Nekudaro, nguva pfupi yadarika mamwe maapplication atanga kuwana mukana wemvura yakavakirwa UV zvakare. Mvura yakavakirwa UV dhijitari kudhinda (inkjet ingi) inogona kubatsirwa kubva kune zvakanakira zvese mvura yakavakirwa (yakaderera viscosity uye yakaderera VOC) pamwe neUV yekurapa ingi (kukurumidza kurapa, kugadzirisa kwakanaka uye kuramba kwemakemikari). Budiriro iri kuenda kumberi nekukurumidza uye zvinokwanisika kuti mamwe akawanda maapplication achakurumidza kuongorora mikana yekushandisa mvura yakavakirwa UV kurapa.
Mvura yakavakirwa UV majasi kwese kupi?
Tose tinoziva kuti pasi redu riri kutarisana nezvimwe zvinetso zviri mberi. Nekuwedzera kwehuwandu hwevanhu uye nekuwedzera mararamiro ehupenyu, mashandisirwo uye saka manejimendi ezvekushandisa anove akanyanya kukosha kupfuura nakare kose. Kurapa kweUV hakuzove mhinduro kune ese aya matambudziko asi inogona kuve chidimbu chimwe chepuzzle sesimba uye zviwanikwa zvehunyanzvi tekinoroji. Traditional solvent borne technologies inoda yakakwirira-simba masisitimu ekuomesa, pamwe nekuburitswa kweVOC. Kurapa kweUV kunogona kuitwa nekushandiswa kwemagetsi mashoma emagetsi e LED kune ingi uye majasi asina kunyungudika kana, sezvatakadzidza munyaya ino, kushandisa mvura chete se solvent. Kusarudza matekinoroji akasimba uye dzimwe nzira dzinogonesa kuti usangochengetedza kicheni yako pasi kana pasherufu yebhuku ine yakakwira-inoita coating, asiwo kudzivirira uye kuziva zviwanikwa zvishoma zvepasi redu.
