Zvizhinji zvezuva nezuva-shandisa zvigadzirwa senge mask, tishu, shati, etc., iva neyakaomeswa sisitiri yekuyedza mwero kudzora mhando yakawanda zvidiki zvidiki. Iyi miyero inoona kuti vatengi vanogona kugamuchira zvinhu nekugutsikana, uye vagadziri vanofanirwa kuvandudza maitiro avo uye mhando zvichiramba zvichiramba. Iyo bvunzo yakaongororwa ichavandudzwa nguva kubva kuzviuru zvebvunzo dzemishumo yebvunzo uye vatengi 'mushure mekutengesa-kutengesa mhinduro.
Nezve pepe tarp kana vinyl tarp bvunzo, pane akawanda ekushanda bvunzo, abrasion-anoramba, anopesana, ini ndichazosvitsa kukosha kwekudzivirira kweUV-kunodzivirira.
Ndedzipi pfungwa dzakakosha dzePolyethyle kana vinyl uv kuramba bvunzo?
● Chikamu cheRradhiace
Iyo huwandu hweUV radiation yakawandisa, kubva ku <.1nm kusvika> 1mm. Chiedza chezuva Ultra-chisimba chiri pakati pe300-400nm, refu wavelength
Pe tarp inogona kushandiswa kwemakore 1-2. Asi kutaura zvazviri, nharaunda neyakanyanya kukwira zvinhu zvinogona kuderedza zvakanyanya nehupenyu hweturpan yemaronda. Pamberi peUV bvunzo, nyanzvi yacho ichaisa zvimwe zvakawanda zvematongerwo enyika semvura, tembiricha, kupembera, kuratidzwa kwezuva, uye mamwe ma parmeters kuti ataure kuchembera muchina. Chikamu cheRiradiace chichava 08-1.0 w / ㎡ / nm, yakafanana neyechokwadi zuva.
● Lamb mhando & zvikumbiro
Fluorescent ultraviolet marambi anogona kunyorera kune ASTM G154 bvunzo. Nekuda kwemhando dzakasiyana-siyana dzezvigadzirwa zvesimbi, izvo zvirevo zvemwenje zvichave zvakasiyana. Iyo 3rd inotariswa mabiko ichavaka iyo nhoroondo yerambi mumushumo.
Iyo laboratori's indoor tembiricha & radiation kure ichapawo huwandu chaihwo hwemarwi akagamuchirwa nemucheka. Saka iyo yekupedzisira radiation paramende ichareva kune iyo chaiyo detectorctor.
● Maitiro ekuenderera mberi kweUV kupokana bvunzo
Pakutanga, sampuke yemucheka ichacheka ne 75x150mm kana 75x300mm uye wobva wagadzirisa nealuminium loop. Isa sampuli mune quv test kamuri uye isa zvese paramita.
0, 100, mazana matatu, 500, 750, 1000, 1500, 2000 maawa anogona kutsigirwa. Iyo quv test kamuri ine kukurudzira inokurumidza basa ne 4x 6x 8x ... kana iyo paramende is 8x, ichangoda maawa gumi nemaviri kuti inomutsa kuratidzwa kwemaawa ezvakasikwa 1000.
Nezve pepe kana vinyl tarp, zvakakwanira samples kuti vagamuchire 300-500 yakakurudzira maawa emaawa. Mushure meizvozvo, nyanzvi yemarabhoritari ichatanga iyo inotevera bvunzo, yakadai seyaruva, kubvarura, kuramba kwemvura. Kuenzaniswa neMuenzaniso wekutanga, mushumo wekupedzisira uchanyudzwa.
