Namhlanje kwazisa ngokufutshane iimpawu ezibonakalayo zeplastiki

1. Ukuphefumla
I-air permeability iphawulwe ngokungena komoya kunye ne-coefficient yomoya.Ukungena komoya kubhekiselele kumthamo (i-cubic metres) yefilimu yeplastiki yobunzima obuthile phantsi koxinzelelo lwe-0.1 MPa kunye nommandla we-square meter (phantsi kweemeko eziqhelekileyo) kwiiyure ezingama-24..I-coefficient ye-Permeability yimali yegesi edlula kwifilimu yeplastiki kwindawo yeyunithi kunye nobukhulu beyunithi ngexesha leyunithi kunye nokwahlukana koxinzelelo lweyunithi (phantsi kweemeko eziqhelekileyo).
2. Ukungena kokufuma
Ukunyamezeka komswakama kubonakaliswa ngumlinganiselo wembono kunye ne-coefficient yombono.Ukungena kokunyakama ngokwenene bubunzima (g) bomphunga wamanzi obufakwe yifilimu ye-square meter e-1 kwiiyure ezingama-24 phantsi kweemeko zomohluko othile woxinzelelo lomphunga kumacala omabini efilimu kunye nobukhulu befilimu ethile.I-coefficient yombono ngumlinganiselo womphunga wamanzi odlula kwindawo yeyunithi kunye nobukhulu befilimu kwiyunithi yexesha phantsi kweyunithi yoxinzelelo lweyunithi.
3. Ukungena kwamanzi
Umlinganiselo wokungena kwamanzi kukujonga ngokuthe ngqo ukunyanzeliswa kwamanzi kwisampuli yovavanyo phantsi kwesenzo soxinzelelo oluthile lwamanzi kwixesha elithile.
4. Ukufunxwa kwamanzi
Ukufunxwa kwamanzi kubhekiselele kumyinge wamanzi afunxayo emva kokuba ubungakanani obuthile bepateni buntywiliselwa kumlinganiselo othile wamanzi adiyiliweyo emva kwexesha elithile.
5. Ubuninzi obuzalanayo kunye nobuninzi
Kwiqondo elithile lobushushu, umlinganiselo wobunzima besampulu ukuya kubunzima bomthamo ofanayo wamanzi ubizwa ngokuba kukuxinana okunxulumeneyo.Ubunzima bento kwiyunithi yevolumu nganye kwiqondo lobushushu obuchaziweyo buba bubuninzi, kwaye iyunithi yi-kg/m³, g/m³ okanye g/mL.
6. Isalathiso seRefractive
Ukukhanya okungena kwiringi yesibini ukusuka kwicandelo lokuqala (ngaphandle kwesiganeko esithe nkqo).I-sine yayo nayiphi na i-engile yesiganeko kunye ne-sine ye-engile ye-refraction ibizwa ngokuba yi-refractive index.Isalathiso se-refractive se-medium ngokubanzi sikhulu kunesinye, kwaye i-medium efanayo inezalathi ze-refractive ezahlukeneyo zokukhanya kwamaza ahlukeneyo.
7. Ukuhanjiswa kokukhanya
Ukucaca kweeplastiki kunokubonakaliswa ngokusasaza ukukhanya okanye inkungu.
Ukuhanjiswa kokukhanya kubhekiselele kwipesenteji yokukhanya okuguquguqukayo okudlula kumzimba ocacileyo okanye ongafihliyo ukuya kwisehlo esikhanyayo.I-transmittance yokukhanya isetyenziselwa ukubonakalisa ukucaca kwezinto.Umlinganiselo osetyenzisiweyo sisixhobo sokulinganisa isibane esipheleleyo, esifana nesphere yasekhaya edibanisa i-A-4 photometer.
Inkungu ibhekiselele kwinkangeleko enamafu kunye nendlongondlongo yangaphakathi okanye umphezulu weeplastiki ezicacileyo okanye eziguquguqukayo ezibangelwa kukusasazwa kokukhanya, okuchazwa njengepesenti yokuphuma kokukhanya okuthe saa emalini kunye nokuhanjiswa kokukhanya.

8. Iglowusi
Iglosi ibhekisa kukwazi komphezulu wento ukubonakalisa ukukhanya, okuchazwa njengepesenti (iglosi) yobungakanani bokukhanya okubonakaliswe kumphezulu osemgangathweni kumkhombandlela oqhelekileyo wokubonisa kwisampulu.
9. Ngundoukushwabana
Ukuncipha kokubumba kubhekisa kubungakanani bobungakanani bemveliso encinci kunobukhulu bomgodi wokungunda mm/mm
