Ibicuruzwa byinshi bya buri munsi nka mask yuburwayi, tissue, ishati, nibindi, mugire gahunda zidasanzwe zitanga umusaruro utaziritse kugirango ugenzure ubuziranenge buto. Aya mahame yemeza ko abaguzi bashobora kwakira ibicuruzwa banyuzwe, kandi abakora bakeneye kunoza inzira zabo nubuziranenge buhoraho. Ikizamini gisanzwe kizavugururwa mugihe kiva kuri raporo ibihumbi n'ibihumbi hamwe nabakiriya nyuma yo kugurisha ibitekerezo.
Regarding the PE tarp or Vinyl tarp test, there are many functional tests such as colorfastness, abrasion-resistant, tear-resistant, etc. In this post, I will introduce the essential UV-resistant test process.
Ni izihe ngingo zikomeye za polyethylene cyangwa vinyl uv ikizamini kirwanya vinyl uv?
Urwego rwa Irradiance
Urutonde rwimirasire ya UV ni nini, kuva <0.1nm kuri> 1mm. Imirasire y'izuba ultra-ihohoterwa riri hagati ya 300-400NM, uburebure burebure uv bujyanye no kwangiza uruhu rwacu, ariko bigira ingaruka ku kwangiza uruhu rwacu, ahubwo bigira ingaruka ku kwangiza uruhu rwacu, ariko bigira ingaruka ku kwangiza abagore benshi, polmers nyinshi zanditseho polymer cyangwa vinyl.
PE tarp irashobora gukoreshwa mumyaka 1-2. Ariko mubyukuri, ibidukikije bifite ibintu byinshi bishaje birashobora kugabanya cyane ubuzima bwiza. Mbere yikizamini cya UV, impuguke izashyiraho byinshi byiyongera ku bidukikije nk'imvura, ubushyuhe, ubushyuhe, urumuri rw'izuba, n'ibindi bipimo kugirango bigana inzira yo gusaza muri mashini. Urwego rwa Irradiance ruzaba 0.8-1.0 w / ㎡ / NM, bisa nizuba ryinshi.
Ubwoko bw'intama & Ibisabwa
Fluorescent Ultraviolet Amatara arashobora gukoreshwa kuri ASTM G154. Kubera ubwoko butandukanye bwibicuruzwa bidafite ibyuma, ibisobanuro byamatara bizaba bitandukanye. Umuburanyi wa 3 ugenzura uzashyira ahagaragara ibisobanuro birambuye kuri raporo.
Ubushyuhe bwa laboratoire & intera y'imirasire nayo izagira ingaruka kumirasire nyayo yakiriwe nicyitegererezo cyambaye imyenda. Ibipimo byanyuma rero bizavuga detector yihariye.
● Nigute wakomeza ikizamini cyo kurwanya UV
Ubwa mbere, icyitegererezo cyambaye imyenda kizagabanywa na 75x150mm cyangwa 75x300mm hanyuma ukosore hamwe na aluminium. Shira icyitegererezo mumigezi ya Quv hanyuma ushireho ibipimo byose.
0, 100, 300, 500, 750, 1000, amasaha 1500, 2000 urashobora gushyigikirwa. Urugereko rwa Quv rufite imikorere yo kwihuta hamwe na 4x 6x 8x ... niba ibipimo ari 8x, bizakenera amasaha 125 gusa kugirango hashizwe amasaha 125 gusa kugirango ashimishe amasaha 125 yo gushimangira amasaha 1000.
Kubijyanye na pe cyangwa vinyl tarp, birahagije byingengonge kugirango wakire amasaha 300-500 yashizwemo. Nyuma yibyo, imfungwa za laboratoire izatangira ikizamini gikurikira, nko guhosha, kurwanya amarira, kurwanya amazi. Ugereranije na sampple yumwimerere, raporo yanyuma izategurwa.
