Iimveliso ezininzi ezisetyenziswa mihla le njengemaski yezonyango, ithishu, ihempe, njl.njl., zinomgangatho ongqongqo wokuvavanya umzi-mveliso ongakhethi cala ukulawula umgangatho kwiinkcukacha ezininzi ezincinci. Le migangatho iqinisekisa ukuba abathengi banokufumana iimpahla ngokwaneliseka, kwaye abavelisi kufuneka baphucule inkqubo kunye nomgangatho wabo ngokuqhubekayo. Umgangatho wovavanyo uya kuhlaziywa kwangexesha ukusuka kumawaka eengxelo zovavanyo kunye nempendulo yabathengi emva kokuthengisa.
Ngokumalunga ne-PE tarp okanye uvavanyo lwe-Vinyl tarp, kukho iimvavanyo ezininzi ezisebenzayo ezifana nombala, u-abrasion-resistant, u-resistant-resistant, njl.
Ngawaphi amanqaku abalulekileyo ovavanyo lwePolyethylene okanye iVinyl UV Resistant?
● Inqanaba le-Irradiance
Uluhlu lwemitha ye-UV lubanzi, ukusuka ku-<0.1nm ukuya kwi>1mm. Ubundlobongela obugqithisileyo bokukhanya kwelanga buphakathi kwe-300-400nm, ubude belanga be-UV ende obunxulumene nokuba yingozi kangako eluswini lwethu, kodwa kuchaphazela ukuthotywa kweepholima ezininzi zeepolima ezininzi ezigqityiweyo njengepolyethylene okanye iVinyl.
I-PE tarp ingasetyenziselwa iminyaka eyi-1-2. Kodwa eneneni, indawo enezinto ezininzi zokuguga inokunciphisa kakhulu ubomi beetarps. Phambi kovavanyo lwe-UV, ingcali iya kuseka izinto ezininzi ezongezelelweyo zokusingqongileyo njengemvula, ubushushu, ukufuma, ukukhanya kwelanga, kunye nezinye iiparamitha ukulinganisa inkqubo yokuguga kumatshini. Inqanaba le-irradiance liya kuba yi-0.8-1.0 W/㎡/nm, efana nokukhanya kwelanga kwangempela.
● Iindidi zeMvana & nezicelo
Izibane ze-Fluorescent ze-ultraviolet zinokusebenza kuvavanyo lwe-ASTM G154. Ngenxa yeentlobo ezahlukeneyo zeemveliso ezingezizo zetsimbi, ukucaciswa kwezibane kuya kuhluka. Iqela lesithathu lolawulo liya kuphawula iinkcukacha zesibane kwingxelo.
Iqondo lobushushu langaphakathi elabhoratri kunye nomgama wokusasazeka ngemitha nako kuya kuba nefuthe elona xabiso lemitha yemitha efunyenwe yisampulu yelaphu. Ke iparamitha yokugqibela yeradiation iya kubhekisa kwisixhobo esithile.
● UluQhuba njani uVavanyo lwe-UV Resistance
Ekuqaleni, isampuli yelaphu iya kunqunyulwa ngu-75x150mm okanye 75x300mm kwaye emva koko ulungise nge-aluminium loop. Beka isampuli kwigumbi lovavanyo lwe-QUV kwaye usete zonke iiparamitha.
0, 100, 300, 500, 750, 1000, 1500, 2000 iiyure zinokuxhaswa. Igumbi lovavanyo lwe-QUV linomsebenzi wokuvuselela isantya kunye ne-4x 6x 8x… Ukuba iparamitha yi-8x, iya kufuna kuphela iiyure eziyi-125 zokwenyani ukuvuselela ukuvezwa kweeyure eziyi-1000 zendalo.
Ngokuphathelele i-PE okanye iVinyl tarp, kwanele ukuba iisampulu zifumane i-300-500 yeeyure ezivuselelweyo. Emva koko, ingcali yebhubhoratri iya kuqalisa uvavanyo olulandelayo, olufana nombala, ukuchasana nokukrazula, ukuxhathisa kwamanzi. Xa kuthelekiswa nesampulu yokuqala, ingxelo yokugqibela iya kuyilwa.
