Ibicuruzwa byinshi-bikoreshwa buri munsi nka mask yubuvuzi, tissue, ishati, nibindi, bifite igipimo gikomeye cyo gupima inganda zitabogamye kugirango ugenzure ubuziranenge kubintu byinshi bito.Ibipimo ngenderwaho byemeza ko abaguzi bashobora kwakira ibicuruzwa banyuzwe, kandi ababikora bakeneye kunoza imikorere yabo nubuziranenge ubudahwema.Ibipimo ngenderwaho bizavugururwa mugihe cyibihumbi n'ibihumbi raporo y'ibizamini hamwe n'ibitekerezo by'abakiriya nyuma yo kugurisha.
Kubyerekeranye na PE tarp cyangwa Vinyl tarp test, hariho ibizamini byinshi byakazi nkibara ryamabara, irwanya abrasion, irwanya amarira, nibindi. Muri iyi nyandiko, nzatangiza inzira yingenzi yo kwipimisha UV.
Ni izihe ngingo zingenzi z'ikizamini cya Polyethylene cyangwa Vinyl UV Resistant?
Level Urwego rwo kurakara
Ikirere cyimirasire ya UV ni kinini, kuva <0.1nm kugeza> 1mm.Imirasire y'izuba ultra-violence iri hagati ya 300-400nm, uburebure bwa UV burebure bujyanye no kutangiza uruhu rwacu, ariko bigira ingaruka kumyuka myinshi ya polymers yangiza polymers nyinshi zarangije ibicuruzwa nka polyethylene cyangwa Vinyl.
PE tarp irashobora gukoreshwa mumyaka 1-2.Ariko mubyukuri, ibidukikije bifite ibintu byinshi byo gusaza birashobora kugabanya cyane igihe cyo kubaho.Mbere yikizamini cya UV, impuguke izashyiraho ibintu byinshi byiyongera kubidukikije nkimvura, ubushyuhe, ubushuhe, urumuri rwizuba, nibindi bipimo kugirango bigereranye gusaza mumashini.Urwego rwa irradiance ruzaba 0.8-1.0 W / ㎡ / nm, rusa nizuba nyirizina.
Ubwoko bwintama & Ibisabwa
Amatara ya Fluorescent ultraviolet arashobora gukoreshwa mubizamini bya ASTM G154.Bitewe nubwoko butandukanye bwibicuruzwa bitari ibyuma, ibisobanuro byamatara bizaba bitandukanye.Ishyaka rya 3 rishinzwe kugenzura rizashyira akamenyetso ku itara muri raporo.
Laboratoire yo mu nzu ubushyuhe & intera intera nayo izagira ingaruka kumirasire yakiriwe nicyitegererezo.Imirasire yanyuma rero izerekeza kuri detector yihariye.
● Nigute Ukomeza Ikizamini cya UV Kurwanya
Ubwa mbere, icyitegererezo cy'imyenda kizacibwa na 75x150mm cyangwa 75x300mm hanyuma gikosorwe hamwe na aluminium.Shira icyitegererezo muri chambre ya QUV hanyuma ushireho ibipimo byose.
Amasaha 0, 100, 300, 500, 750, 1000, 1500, 2000 arashobora gushyigikirwa.Icyumba cyibizamini cya QUV gifite imbaraga zo kwihutisha imikorere hamwe na 4x 6x 8x… Niba ibipimo ari 8x, bizakenera gusa amasaha 125 nyayo kugirango ushishikarize kwerekana amasaha 1000 asanzwe.
Kubyerekeranye na PE cyangwa Vinyl tarp, birahagije ko ingero zakira amasaha 300-500 yakangutse.Nyuma yibyo, impuguke ya laboratoire izatangira ikizamini gikurikira, nko kurya amabara, kurwanya amarira, kurwanya amazi.Ugereranije nicyitegererezo cyambere, raporo yanyuma izategurwa.
