UV-9 (BP-3): Choteteza chomwe chimayamwa mafunde ambiri, cholimba, chosagwedezeka ndi nyengo, komanso choteteza ku dzuwa cha Class Ⅰ chovomerezeka ndi FDA, komanso choyamwa ma ultraviolet chomwe chimakonda kwambiri pazinthu zowala komanso zowonekera bwino.

Choyamwa cha ultraviolet UV-9 (BP-3, CAS: 131-57-7) ndi choyamwa cha ultraviolet chopangidwa ndi benzophenone. Ndi choyamwa cha sunscreen cha Class Ⅰ chovomerezedwa ndi US FDA, chokhala ndi mphamvu zoyamwa za UV-A ndi UV-B ziwiri. Chimatha kugwira bwino kuwala kwa ultraviolet komwe kumakhala pakati pa 270-340nm, kusintha mphamvu ya ultraviolet kukhala mphamvu yotentha yopanda vuto kudzera mu kusintha kwa kapangidwe ka mamolekyulu, ndikuchepetsa kuwonongeka kwa kuwala kwa ultraviolet kuzinthu. Chogulitsachi chili ndi kukhazikika kwabwino kwa photothermal, chimagwirizana bwino ndi zinthu zosiyanasiyana, sichimayambitsa poizoni, sichimayambitsa teratogenic, sichimayenda bwino komanso sichisinthasintha, chimasintha malinga ndi zosowa za zinthu zowonekera zopanda utoto/zowala, ndipo chimagwiritsidwa ntchito kwambiri mu mapulasitiki, zokutira, rabara, zodzoladzola za sunscreen ndi zina. Ndi njira yothandiza yotetezera ultraviolet yomwe imayesa magwiridwe antchito ndi chitetezo.

Ubwino wa Zinthu Zazikulu:

Kuyamwa kwa mafunde kochuluka komanso kogwira mtima: Kuchuluka kwa kuyamwa kumafika pa 288nm ndi 326nm, kumaphimba bwino gulu la ultraviolet la 270-340nm. Lili ndi mphamvu yoyamwa mafunde ambiri, limasintha mphamvu ya ultraviolet mwachangu, ndipo limachepetsa kwambiri zoopsa za kujambula zithunzi, chikasu, ndi kutayika kwa kuwala.

Kukhazikika kwabwino: Kuli ndi kukhazikika kwabwino kwa kuwala, kutentha, ndi mankhwala. Palibe mvula kapena kuwonongeka kwa zinthu zomwe zimagwiritsidwa ntchito panja komanso kutentha kwambiri, ndipo chitetezo chake chimakhala chokhazikika komanso chokhalitsa.

Kusinthasintha kwamphamvu kwa substrate: Imagwirizana bwino kwambiri ndi mapulasitiki osiyanasiyana, ma resin, ndi makina okutira monga polyvinyl chloride, polyurethane, ndi acrylic resin, ndipo imatha kufalikira bwino. Sichikhudza mawonekedwe oyamba ndi mankhwala a substrate, ndipo ndi yoyenera makamaka pazinthu zowala komanso zowonekera.

Yotetezeka, yosamalira chilengedwe, komanso yogwirizana ndi malamulo: Siili ndi mphamvu yowononga chilengedwe, yotsika kusinthasintha, komanso yosasuntha kwambiri. Imakwaniritsa miyezo yamakampani aku America ndi ku Europe. Siyokha yongopangira zinthu zoteteza ku dzuwa zomwe zavomerezedwa ndi FDA komanso imatha kukwaniritsa zofunikira zoteteza chilengedwe pazinthu zamafakitale.

Kugwiritsa ntchito ndalama zambiri: Kuchuluka kowonjezerako kungapangitse chitetezo chogwira ntchito bwino, palibe chifukwa chosinthira njira yopangira, zomwe zimathandiza kuchepetsa mtengo wonse wa mabizinesi omwe ali mu ulalo woteteza ku kukana nyengo.

Imagwira ntchito pa Magawo Ambiri ndi Zochitika Zonse:

Potengera magwiridwe antchito ake abwino kwambiri, UV-9 (BP-3) ingagwiritsidwe ntchito kwambiri m'magawo anayi akuluakulu: ma resini apulasitiki, zokutira ndi inki, rabara yopangidwa, ndi zodzoladzola zoteteza ku dzuwa, zomwe zimagwirizana ndi zosowa za chitetezo cha ultraviolet cha zinthu zosiyanasiyana zowala/zowonekera:

Ma resini apulasitiki: Chitetezo chopepuka cha kukalamba kwa zinthu monga polyvinyl chloride, polyurethane, polymethyl methacrylate, ma resini a ABS/AS, ndi ma resini osakhuta.

Zophimba ndi inki: Zimathandiza kuti utoto wa mafakitale, utoto wamatabwa, ndi inki zosiyanasiyana zosindikizira zisamawonongeke ndi nyengo, zomwe zimathandiza kuti utotowo usawonongeke, usinthe mtundu, komanso kuti usamasweke.

Rabala yopangidwa: Chitetezo chopepuka cha zinthu zosiyanasiyana zopangidwa ndi rabala, kuchepetsa kuuma ndi kusweka kwa kuwala komwe kumachitika chifukwa cha kuwala kwa ultraviolet.

Zodzoladzola zoteteza ku dzuwa: Chodzoladzola chachikulu cha dzuwa chomwe chimagwiritsidwa ntchito popanga mafuta odzola, mafuta odzola, mafuta odzola, ndi zina zotero. Ndi chinthu chodziwika bwino m'misika ya ku America ndi ku Ulaya ndipo chingagwiritsidwenso ntchito ngati choletsa kusintha kwa mtundu wa zinthu zomwe zimakhudzidwa ndi kuwala kwa dzuwa.

Mtengo Waukulu wa Chinthu:

Imapereka chitetezo cha ultraviolet cha moyo wonse pazinthu kuyambira pakupanga ndi kukonza mpaka kugwiritsa ntchito panja, imateteza mawonekedwe oyambirira ndi mawonekedwe enieni a zinthu zowala/zowonekera, imachedwetsa mavuto monga kuwonongeka kwa zinthu, chikasu, ndi kutayika kwa kuwala, ndipo imawongolera kwambiri moyo wokana nyengo komanso mpikisano pamsika wa zinthu. Nthawi yomweyo, imaganizira momwe zinthu zimasinthira popanga mafakitale komanso chitetezo cha zodzoladzola, kukwaniritsa zosowa ziwiri za chitetezo cha zinthu zamafakitale ndi mafuta oteteza dzuwa tsiku lililonse nthawi imodzi.

Mgwirizano ndi Kupatsa Mphamvu:

Ndi njira yotsika mtengo yotetezera kuwala kwa ultraviolet, timapatsa mphamvu makasitomala m'mafakitale osiyanasiyana kuti akweze zinthu zawo, kusintha momwe amafunira zinthu zosiyanasiyana, kuthandiza zinthu kuthana ndi mavuto omwe angabwere chifukwa cha nyengo, komanso kukulitsa mpikisano pamsika.
