Utoto wa UV ndi gawo lofunikira pakupaka kwa UV

Utoto wa UV umapangidwa ndi polymer ndi zida zokomera zachilengedwe komanso umisiri watsopano.Ili ndi kuuma kwapang'onopang'ono, yotengera madzi, palibe kuipitsidwa kwa VOC, kawopsedwe kakang'ono, osayaka, kumamatira bwino pamapepala, kusinthasintha kwabwino.Mankhwalawa amatha kuchepetsedwa ndi madzi malinga ndi kukhuthala kwa ma viscosity.The mamasukidwe akayendedwe a mankhwala ndi zolimbitsa, ndipo inki ndi bwino ❖ kuyanika wodzigudubuza ndi makina inki kusindikiza.Mankhwalawa ndi achikasu komanso omveka bwino.Pambuyo kuchiritsa, filimu ya utoto imawonekera kwambiri ndipo imatha kugwiritsidwa ntchito ndi ma monomers ena amafuta kuti apeze kuuma kwakukulu komanso kukana kukanda kwambiri, Makhalidwe: mawonekedwe otsika kwambiri otsika kukhuthala kwapadera kwa Polyurethane Acrylic UV resin, yomwe imakhala ndi zomatira zapadera, kukana kuwira, kukana kuwira kwamadzi ndi makhalidwe ena pamwamba magalasi inorganic ndi hardware.Ndi bwino matumba ndudu, matabwa dera, galasi, hardware, zoumba ndi zipangizo zina.
 
UV utomoni ntchito: otsika mamasukidwe akayendedwe, makamaka oyenera UV inki-ndege ndi 3D yosindikiza, ndi wettability wabwino, otsika mamasukidwe akayendedwe, okhutira mkulu olimba ndi otsika shrinkage, adhesion wabwino kwa galasi ndi zitsulo, kukana mankhwala, madzi kuwira kukana ndi madzi kuwira kukana.Mtundu wa ntchito: UV inki-jet, kusindikiza kwa 3D, inki ya UV pagalasi, zida, inki ya UV pa ceramic, UV alkali wochapira inki, galasi UV guluu, ndi zina. Utoto wa UV umapangidwa ndi polima monomer ndi prepolymer, momwe kuwala (ultraviolet ) woyambitsa (kapena photosensitizer) akuwonjezeredwa.Pansi pa kuyatsa kwa kuwala kwa ultraviolet (250-300 nm) ya kutalika kwinakwake, ma polymerization amachititsidwa nthawi yomweyo kumaliza kuchiritsa.Photosensitive resin nthawi zambiri imakhala yamadzimadzi, ndipo imagwiritsidwa ntchito popanga zinthu zokhala ndi mphamvu zambiri, kukana kutentha kwambiri komanso kusalowa madzi.

Utoto wa UV ndi gawo limodzi la zokutira za UV, ndipo ndi utomoni wa matrix mu zokutira za UV.Nthawi zambiri, ili ndi magulu omwe amatha kuchitapo kanthu kapena kupanga polymerize pansi pamikhalidwe yopepuka, monga mpweya wa carbon double bond ndi gulu la epoxy.Malinga ndi mtundu wa zosungunulira, UV utomoni akhoza kugawidwa mu zosungunulira mtundu UV utomoni ndi amadzimadzi UV utoni zosungunulira zochokera utomoni zilibe magulu hydrophilic ndipo akhoza kusungunuka mu zosungunulira organic, pamene utomoni amadzimadzi muli magulu hydrophilic kapena zigawo hydrophilic ndipo akhoza kusungunuka. kukhala emulsified, omwazika kapena kusungunuka m'madzi.Ma resin amadzimadzi a UV amatanthauza ma resin a UV omwe amasungunuka m'madzi kapena amatha kumwazikana m'madzi.Mamolekyuwa ali ndi gulu lina lamagulu amphamvu a hydrophilic, monga carboxyl, hydroxyl, amino, ether, acylamino, ndi zina zambiri, ndi magulu a unsaturated, monga acryloyl, Methacryloyl kapena allyl.Mitengo ya UV yamadzi imatha kugawidwa m'magulu atatu: mtundu wa lotion, mtundu wa kubalalitsidwa kwamadzi ndi mtundu wosungunuka m'madzi Zimaphatikizapo magulu atatu: polyurethane acrylate yamadzi, epoxy acrylate yamadzi ndi polyester acrylate yamadzi.
