Zvizhinji zvemazuva ese-zvinoshandiswa zvigadzirwa senge mask yekurapa, matishu, hembe, nezvimwe, zvine yakaomesesa isina kurerekera indasitiri yekuyedza chiyero chekudzora mhando pane zvakawanda zvidiki. Aya mazinga anovimbisa kuti vatengi vanogona kugamuchira zvinhu nekugutsikana, uye vagadziri vanofanirwa kuvandudza maitiro avo uye mhando nguva dzose. Iyo chiyero chekuyedza ichagadziridzwa nenguva kubva kuzviuru zveyedzo mishumo uye vatengi mushure mekutengesa mhinduro.
Nezve PE tarp kana Vinyl tarp bvunzo, kune akawanda anoshanda bvunzo akadai colorfastness, abrasion-resistant, misodzi, etc. Mune ino post, ini ndichasuma yakakosha UV-resistant test process.
Ndeapi mapoinzi akakosha ePolyethylene kana Vinyl UV Resistant bvunzo?
● Irradiance Level
Huwandu hwemwaranzi yeUV hwakakura, kubva pa <0.1nm kusvika> 1mm. Chiedza chezuva chekupedzisira-chisimba chiri pakati pe300-400nm, yakareba wavelength UV ine hukama nekusanyanya kukuvadza paganda redu, asi inokanganisa akawanda mapolymer 'kuora kweakawanda mapolymer akapedzwa zvigadzirwa senge polyethylene kana Vinyl.
PE tarp inogona kushandiswa kwemakore 1-2. Asi kutaura zvazviri, nharaunda ine zvinhu zvakawandisa zvekuchembera inogona kuderedza zvakanyanya hupenyu hwetarps. Pamberi peiyo UV bvunzo, nyanzvi inoisa akawanda ekuwedzera ezvemamiriro ekunze senge mvura, tembiricha, hunyoro, kuratidzwa kwezuva, uye mamwe ma paramita kutevedzera kuchembera mumushini. Iyo irradiance level ichave 0.8-1.0 W/㎡/nm, yakafanana nechiedza chezuva chaicho.
● Mhando dzeGwayana & Zvikumbiro
Fluorescent ultraviolet marambi anogona kushanda kune ASTM G154 bvunzo. Pamusana pemhando dzakasiyana-siyana dzezvigadzirwa zvisiri zvesimbi, zvinyorwa zvemwenje zvichave zvakasiyana. Bato rechitatu rekutarisa richamaka ruzivo rwemwenje mumushumo.
Tembiricha yemukati yerabhoritari & kureba kwemwaranzi kuchakanganisawo huwandu chaihwo hwemwaranzi inogamuchirwa nejira remuenzaniso. Saka iyo yekupedzisira radiation parameter ichareva kune chaiyo detector.
● Mafambiro Ekuita Iyo UV Resistance Test
Pakutanga, muenzaniso wejira uchachekwa ne75x150mm kana 75x300mm uye wozogadzirisa nealuminium loop. Isa sampuli mukamuri yekuyedza yeQUV uye isa ese ma paramita.
0, 100, 300, 500, 750, 1000, 1500, 2000 maawa anogona kutsigirwa. The QUV test room ine stimulate accelerating function ne 4x 6x 8x… Kana parameter iri 8x, inongoda maawa zana nemakumi maviri neshanu chete kuti ikurudzire kuratidzwa kwe1000 maawa echisikigo.
Nezve PE kana Vinyl tarp, zvakakwana kuti masampuli agamuchire 300-500 inokurudzirwa maawa 'kuratidzwa. Mushure maizvozvi, nyanzvi yerabhoritari ichatanga bvunzo inotevera, yakadai seye colorfastness, kubvarura kuramba, kushomeka kwemvura. Kuenzaniswa nemuenzaniso wekutanga, mushumo wekupedzisira uchanyorwa.
