Uninzi lweemveliso ezisebenzisa imaski yezonyango, izicubu, ihempe, njlnjl. Le migangatho iqinisekisa ukuba abathengi banokufumana iimpahla ngolwaneliseko, kwaye abavelisi kufuneka baphucule inkqubo yabo kunye nomgangatho ngokuqhubekayo. Umgangatho wovavanyo uya kuhlaziywa ngexesha elifanelekileyo ukusuka kumawakawaka eengxelo zovavanyo kunye nengxelo yokuthengisa yabathengi emva kokuthengisa.
Ngokuphathelele i-PE TARP okanye uvavanyo lwe-vinyl lwe-vinyl, zininzi iimvavanyo ezinje ngemibalabala, enganyangekiyo-enganyangekiyo, intengo, njl.
Ngawaphi amanqaku abalulekileyo kwi-polyethylene okanye uvavanyo lwe-vinyl uv?
● Inqanaba le-Irradiance
Uluhlu lwe-radiation ye-UV lubanzi, ukusuka kwi <0.1NM kwi-1mm. I-Utrani yokukhanya ilanga iphakathi kwe-300-400nm, i-wavelengd ye-UV enxulumene nokuyingozi kakhulu kulusu lwethu, kodwa ichaphazela ukonakaliswa kwePolymers ezininzi kwi-polythylene okanye i-vinyl.
I-PET isetyenziselwa iminyaka emi-1 yesi-2. Kodwa enyanisweni, indalo enezinto ezininzi zokwaluphala zinokunciphisa kakhulu ixesha lokuphila. Phambi kovavanyo lwe-UV, ingcali iya kubeka izinto ezininzi ezongezelelekileyo zokusingqongileyo ezinjengemvula, amaqondo obushushu, ukuvezwa kwelanga, kunye nezinye iiparamitha zokulinganisa inkqubo yokwaluphala kumatshini. Inqanaba le-Irradiance iya kuba yi-0.8-1.0 w / ㎡ / nm, ifana nokukhanya kwelanga.
● Iindidi zemvana kunye nezicelo
Izibane ze-fluorescent ze-fluorescent zinokufaka isicelo kuvavanyo lwe-ASTM G154. Ngenxa yeentlobo ezahlukeneyo zeemveliso ezingezizo zentsimbi, imigaqo yezibane ziya kwahluka. Iqela le-3Dervidion ye-3 le-3 liya kuphawula iinkcukacha zesibane kwingxelo.
I-Laboratory's I-Indoratory ye-Indoor kunye ne-radiation iya kuba nefuthe lelona nani le-radiation elifunyenwe yisampulu yefabhari. Ke iparamitha ye-radiation ye-radiation iya kubhekisa kumzisi othile.
● Ukuqhubeka njani kuvavanyo lokuchasana no-UV
Ekuqaleni, isampulu yendwangu iya kunqunyulwa yi-75x150mm okanye i-75X300mm kwaye emva koko ilungiswe nge-aluminium loop. Beka isampulu kwigumbi lovavanyo lweQu qoko kwaye useta zonke iiparameter.
I-0, 100, 300, 500, i-500, i-1000, i-1500, 2000 iiyure inokuxhaswa. Igumbi lokuvavanya i-quv likhuthaze umsebenzi wokukhawulezisa nge-4x 6x 3x ... ukuba iparameter yi-8x, iya kufuna iiyure ezili-125 zokwenyani ukukhuthaza i-1000 yeeyure zendalo.
Ngokuphathelele i-PE okanye i-vinyl ye-tarp, yanele iisampulu ukufumana iiyure ezingama-300-500 ezivuselelekileyo. Emva koko, ingcali yelebhu iya kuqala lo mvavanyi okulandelayo, njengamaxabiso alandelayo, ukuxhathisa kwamaxabiso, ukumelana namanzi. Xa kuthelekiswa nesampulu yoqobo, ingxelo yokugqibela iyaliwe.
