ASTM D1003 yakajairwa bvunzo yeHaze uye kujekesa kuputika kwemapurasitiki ezvibodzwa
Haze ndiyo mhedzisiro yekushomeka kwekutapurirana kwechiedza kuburikidza neyakajeka zvinhu, zvichikonzera kuoneka kwakashata uye / kana glare. Kuongorora izvi mhedzisiro inonzi haze yeiyo solids uye turbidity yezvinwiwa.
Haze inogona kuve yezvinhu-yakatarwa, mhedzisiro yekuumbwa, kana mhedzisiro yekugadzirisa kwemusoro; Inogona zvakare kuve iyo mhedzisiro yezvinhu zvakatipoteredza senge mamiriro ekunze kana pamusoro pearasion. Transmittance inoongorora huwandu hwechiedza chinopfuura kuburikidza nemuenzaniso. Naizvozvo, haze uye turmittance zviyero zvinogona kushandiswa kukura kwechigadzirwa, kugadzirisa kukura uye kupera-kushandisa kwekuita kwekuita. Transmittance uye Haze akaenderana, asi kwete zvakadaro; Discouse transmittance pachayo muchimiro chehasha kana smoky hazy yakakonzerwa nekuparadzira mwenje sezvo ichipfuura nepamhepo kana pepa rechinhu kana vachiona chinhu kuburikidza nezvinhu; kana muchimiro chehodhi glare inoonekwa pane mhepo yemhepo yemotokari uchityaira muzuva.
Nepo zviyero zvidiki zvinowanzoitwa nemumetambo ane haze, iyo spectrophotometer inogona zvakare kushandiswa kwenguva yakareba sezvazvinosangana neiyo geometric uye yekufungidzira zvinodiwa. Kuyera iyo haze yevapurasitiki uchishandisa spectrophotometer inogona kupa yakakosha idziviriro data pane sosi yehaze.
Kune maviri maprotocols ekuyera Haze pasi peASTM D1003, ne protocol a (Haze mita nzira) zvishoma nezvishoma pane protocol b (spectrophoterter nzira) bvunzo dzebvunzo.
Kune samples dzakajeka dzakaiswa chinhambwe kubva kuKubatanidza Sphaketi incle, kutapurirana kwakananga kwechiedza chemuenzaniso kunogona kuyerwa. Nekudaro, kana sampuli ichiratidzirwa, iyo yakazara kutapurika inofanirwa kuyerwa nekuisa muenzaniso kune iyo nzvimbo yekubatanidza nzvimbo yekubatanidza. Iyo yakayerwa yakazara inotapukira ichave yakakura kupfuura yenguva dzose kuendesa, zvichienderana nezvinhu zvekunze zvemienzaniso.
Kuyera Haze, nzira yechipiri inofanirwa kushandiswa, kureva kuti, sampuli inofanira kugara ichiswededzwa padhuze nekubatanidza
Chenjera chinofanira kutorwa kuti muenzaniso uri pasi pemuedzo unodzivirira heterogeniessogensogens kana kuremara kwemukati zvisina hunhu kwechinyorwa, kuitira kuti irege yemumiriri wezvinyorwa zvinogona kuwanikwa. Asati ataura muedzo, hunhu hwezvinyorwa zviri pasi pebvunzo zvinofanirwa kutariswa, uye kufungidzira, zviyero zvezvinyorwa zvebvunzo zvinofanirwa kuve zvakatsanangurwa kuti uve nechokwadi chekuti data iri kubereka. ASTM D1003 Muedzo nzira haina kuenzana neicho ISO 13468-1 uye iso / Dha 14782.
Iyo ASTM D1003 bvunzo nzira inonyanya kuve nehanya neyakaongorora kumwe kuendesa mwenje uye yakafara mwenje kuparadzira zvivakwa zvezvirongwa zvechirongwa zvinhu (semuenzaniso, pachena mapurasitiki). Mapuroteni maviri anopihwa kutapurirwa kwechiedza uye haze zviyero. Protocol inoshandisa iyo in the haze metres nzira uye protocol b iyo nzira yekutarisa nzira. Zvishandiso neHaze Hukuru hwakakura kupfuura 30% dzinoonekwa dzisimba uye hazvina kukodzera nzira iyi uye inoda kuedzwa nenzira yeASTM E2387.
