Lihlahisoa tse ngata tsa letsatsi le letsatsi joaloka maske a mangata a bophelo Melao ena e tiisa hore bareki ba ka fumana thepa ka khotsofalo le khotsofalo ea batho ba ka hlokang ho ntlafatsa tšebetso ea bona le boleng ba bona kamehla. Tekanyetso ea Teko e tla ntlafatsoa ka nako ho tloha litlalehong tse likete le bareki ka mor'a ho rekisa ka mor'a moo.
Mabapi le tlhahlobo ea VUNP kapa Vinyl Panc
Lintlha tse nyarosang tsa polyethylene kapa vinyl UV e loantšanang le li-uv tse thibelang?
● Boemo ba inradiance
Liphetoho tsa radiation tsa UV e atile, ho tloha <0.1nm ho> 1mm. Lebelo la Ntoa ea Letsatsi-ultra - le amang batho ba bangata ba nang le thepa ea tšepe e neng e sentse lihlahisoa tse kang polyethylene kapa vinyl.
PATP e ka sebelisoa lilemo tse 1-2. Empa ha e le hantle, tikoloho e nang le lintho tse ngata tse tsofetseng e ka fokotsa bophelo bo botle ba literata. Pele ho tlhahlobo ea UV, setsebi se tla beha likarolo tse ngata tsa tikoloho tse tšoanang le pula, mocheso, mongobo, mongobo o hlakileng le maemo a mang ho etsisa ts'ebetso ea botsofali mochining. Boemo ba inradiance bo tla ba 0.8-1.0 w / ㎡ / nm, e ts'oanang le khanya ea letsatsi.
● Mefuta ea Likopano le Liteko
Mabone a fluorescent ultraviolet a ka sebetsa tekong ea astm g154. Ka lebaka la mefuta e fapaneng ea lihlahisoa tseo e seng tsa tšepe, litlhaloso tsa mabone li tla fapana. Mokhahlelo oa 3 oa tlhokomeliso ea 3 o tla tšoaea lintlha tsa lebone tlalehong.
Sebaka sa ka hare tsa laboratori le radiation e tla ama mahlaseli a mangata a ratoang ke sampole ea lesela. Kahoo paramente ea ho qetela ea radiation e tla bua ka tšiloho e khethehileng.
● Tsela ea ho tsoela pele ka tlhahlobo ea UV ea ho hanyetsa
Qalong, sampole ea lesela e tla khaoloa ka 75x150mm kapa 75x300mm ebe e lokisa ka loop ea aluminium loop. Beha sampole ka phapusing ea liteko tsa quv ebe u beha litekanyetso tsohle.
0, 100, 300, 500, 750, 5000, lihora tse 1500, lihora tse 2000 li ka tšehetsoa. Kamore ea liteko ea QuV e na le ts'ebetso e potlakileng ea 4x 6x ... Haeba paramente e 8x, e tla hloka lihora tse 125 ho eletsa ho pepesetsoa lihora tse 1000.
Mabapi le pe kapa vinyl tarp, ho lekane disampole ho amohela li-deples tse 300-500. Kamora moo, setsebi sa laboratoriki se tla qala phuputso e latelang, joalo ka borika, ho hanyetsa, ho hanyetsa metsi. Ha ho bapisoa le sampole ea mantlha, tlaleho ea ho qetela e tla tšeloa.
