UV-9 (BP-3): Ni ikirahure cy’urumuri gikingira imiraba myinshi, gikingira izuba mu buryo buhoraho, kidahindagurika, kandi gifite ubushobozi bwo guhangana n’imihindagurikire y’ikirere, kandi gifite ubushobozi bwo gukoresha FDA mu gupima izuba, hamwe n’ikirahure cy’urumuri gikunzwe cyane ku bikoresho bifite amabara y’urumuri kandi bibonerana.

UV-9 (BP-3, CAS: 131-57-7) ni icyuma gikoresha imirasire ya ultraviolet gikoreshwa muri benzophenone. Ni igikoresho gikingira izuba cyo mu rwego rwa Ⅰ cyemewe na FDA yo muri Amerika, gifite ubushobozi bwo gufata imirasire ya ultraviolet ifite uburebure bwa 270-340nm, gihindura ingufu za ultraviolet mu bushyuhe butagira ingaruka mbi binyuze mu guhindura imiterere ya molekile, kandi kikagabanya cyane kwangirika kw'imirasire ya ultraviolet ku bikoresho. Iki gicuruzwa gifite ubushobozi bwo guhagarara neza mu bushyuhe, gihura neza n'ibintu bitandukanye, ntigihumanya, ntigitera teratogenic, gifite ubwihindurize buke kandi budahinduka cyane, kimenyera ibikenewe mu kurinda ikirere ku bicuruzwa bidafite ibara/amabara yoroheje, kandi gikoreshwa cyane mu mapulasitiki, mu gusiga irangi, mu byuma bisiga imirasire ya ultraviolet n'ibindi. Ni igisubizo cyiza cyo kurinda imirasire ya ultraviolet gipima imikorere n'umutekano.

Ibyiza by'ingenzi ku bicuruzwa:

Uburyo bwo gufata neza imiraba: Ingano y’ingufu igera kuri 288nm na 326nm, itwikira neza umugozi wa ultraviolet wa 270-340nm. Ifite ubushobozi bwo gufata neza imiraba, ihindura vuba ingufu za ultraviolet, kandi igabanya cyane ibyago byo gufotora ibintu, guhinduka umuhondo no gutakaza urumuri.

Ituje cyane: Ifite urumuri rwiza, ubushyuhe, n'imiti ihamye. Nta mvura cyangwa ngo ibore mu buryo bushyuha cyane no mu bikorwa byo hanze, kandi ingaruka zo kurinda ibidukikije ziraramba kandi zirahamye.

Ishobora kwihuza neza na substrate: Ikorana neza na pulasitiki zitandukanye, resins, na sisitemu zo gusiga nka polyvinyl chloride, polyurethane, na acrylic resin, kandi ishobora gukwirakwira neza. Ntigira ingaruka ku miterere y'umwimerere n'imiti by'ibanze bya substrate, kandi ikwiriye cyane cyane ibicuruzwa bifite ibara ryoroheje kandi ribonerana.

Ifite umutekano, irinda ibidukikije, kandi yubahiriza amategeko: Nta ngaruka igira ku miterere y’umubiri, nta guhindagurika cyane, kandi nta kwimuka cyane. Yujuje ibisabwa n’inganda za Amerika n’i Burayi. Si ibikoresho fatizo byo kwisiga bifite ibara ry’izuba byemejwe na FDA gusa, ahubwo ishobora no kubahiriza ibisabwa mu kurengera ibidukikije ku bikoresho by’inganda.

Ikiguzi cyo gukoresha kiri hejuru: Inyongera nto ishobora kugera ku burinzi bunoze, nta mpamvu yo guhindura uburyo bwo gukora, bityo bigabanye neza ikiguzi cy’ibigo mu bijyanye no kurinda imihindagurikire y’ikirere.

Bikoreshwa ku Mishinga myinshi n'Imiterere yuzuye:

Bishingiye ku mikorere yayo myiza cyane, UV-9 (BP-3) ishobora gukoreshwa cyane mu bice bine by'ingenzi: resins za pulasitiki, irangi n'inyi, rabu y'ubukorikori, n'amavuta yo kwisiga akingira izuba, bihuye n'ibikenewe mu kurinda imirasire y'izuba ku bikoresho bitandukanye by'amabara y'urumuri/ibibonerana:

Resine za pulasitiki: Uburinzi bworoheje bwo gusaza ku bicuruzwa nka polyvinyl chloride, polyurethane, polymethyl methacrylate, resine za ABS/AS, na resine zitaraseye.

Irangi n'inyi: Bituma amarangi yo mu nganda, amarangi y'ibiti n'andi akoreshwa mu gucapa adashobora guhangana n'ikirere, bikarinda ko irangi ritakaza ububengerane, ihinduka ry'ibara, n'ivunika.

Rubber y'ubukorikori: Uburinzi bworoheje ku bikoresho bitandukanye bya rubber y'ubukorikori, bigabanya gukomera no kwangirika guterwa n'imirasire ya ultraviolet.

Amavuta yo kwisiga akingira izuba: Ni ibikoresho by'ingenzi bisiga amavuta yo kwisiga akingira izuba, amavuta yo kwisiga, amavuta yo kwisiga, n'ibindi. Ni amahitamo azwi cyane ku masoko ya Amerika n'i Burayi kandi ashobora no gukoreshwa nk'umuti urwanya ibara ry'uruhu ku bicuruzwa bishobora kwanduza ubwiza bw'izuba.

Agaciro k'ingenzi k'ibicuruzwa:

Itanga uburinzi bw'ubuzima bwose bwa ultraviolet ku bikoresho kuva ku gukora no gutunganya kugeza ku gukoreshwa hanze, irinda imiterere y'umwimerere n'imiterere y'ibicuruzwa bifite ibara ryoroheje/ribonerana, idindiza ibibazo nko kwangirika kw'ibikoresho, umuhondo, no gutakaza urumuri, kandi irushaho kunoza cyane ubuzima bwo guhangana n'ikirere n'ipiganwa ry'ibicuruzwa ku isoko. Muri icyo gihe, yita ku buryo umusaruro w'inganda uhinduka n'umutekano w'ikoreshwa ry'ubwiza, ihaza ku bintu bibiri birinda ibikoresho by'inganda ndetse n'isuku y'izuba ya buri munsi mu mwanya umwe.

Ubufatanye n'Ubushobozi:

Dukoresheje uburyo bwo kurinda urumuri ruhenze kandi ruhendutse, duha abakiriya bo mu nganda zitandukanye ubushobozi bwo kuvugurura ibicuruzwa byabo, tugakora uko dushoboye kugira ngo duhuze n’ibyo bakeneye mu bihe bitandukanye byo gukoreshwa, dufashe ibicuruzwa kurenga imbogamizi zo guhangana n’ikirere, kandi twongere ubushobozi bwo guhangana n’isoko.
