Miyezo 7 Yoyesa Kukaniza Kwanyengo kwa Zopaka Ufa

Pali miyezo 7 yoyesa kukana kwanyengo zokutira za ufa.

• Kukaniza matope
• Kukalamba kofulumira komanso kulimba kwa UV (QUV)
• Saltspraytest
• Kesternich - mayeso
• Florida-mayeso
• Humiditytest (nyengo yotentha)
• Kukaniza Chemical

Kukaniza matope

Malinga ndi muyezo ASTM C207. Dongo linalake lidzakhudzidwa ndi zokutira ufa pa 24h pa 23 ° C ndi 50% chinyezi chapafupi.

Kukalamba kofulumira komanso kulimba kwa UV (QUV)

Mayesowa mu QUV-waerometer amakhala ndi mikombero iwiri. Ma testpanels okhala ndi 2h amawululidwa ndi kuwala kwa UV ndi 8h ku condensation. Izi zikubwerezedwa nthawi ya 4h. 1000h iliyonse mapanelo amafufuzidwa. Apa zokutira zimayesedwa pa mtundu- ndi kusunga gloss.

Kuyesa kwamchere wamchere

Malinga ndi miyezo ya ISO 9227 kapena DIN 50021. Mapanelo opangidwa ndi ufa (omwe ali ndi mtanda wa andreas wokanda pakati pa filimuyo) amayikidwa pamalo ofunda achinyezi ndikupopera mchere. Mayesowa amawunika kuchuluka kwa chitetezo kuchokera ku zokutira kupita ku dzimbiri pamalo amchere (mwachitsanzo m'mphepete mwa nyanja). Nthawi zambiri testcase iyi imatenga 1000h, macheke amachitidwa 250h iliyonse.

Kesternich - mayeso

Malinga ndi miyezo ya DIN 50018 kapena ISO3231. Amapereka chidziwitso chabwino cha kukana kwa zokutira m'malo opangira mafakitale. Kwa nthawi yeniyeni gulu loyesera lophimbidwa limayikidwa pamalo ofunda a chinyezi, omwe ali ndi sulfure dioxide. Mayesowa akuyendetsa 24h-mkombero ndikuwongolera 250h iliyonse.

Florida-mayeso

Pazaka zosachepera 1 ma testpanels okutidwa amakhala padzuwa komanso chinyezi ku Florida, USA. Kuwala komanso kusungidwa kwamtundu kumawunikidwa.

Kuyesa chinyezi (nyengo yotentha)

Malinga ndi miyezo ya DIN 50017 kapena ISO 6270. Imaphedwa m'chipinda chokhala ndi chinyezi chochuluka, pa kutentha kwakukulu ndipo nthawi zambiri pa 1000h. Aliyense 250h ulamuliro akuphedwa pa ufa TACHIMATA mapanelo ndi Andreas-mtanda zikande ndi mpeni kudzera filimu pakati. Mayesowa amayesa kugwa kwa chinyezi ndi dzimbiri m'malo achinyezi.

Kukaniza Chemical

Kukaniza kwa Chemical Nthawi zambiri amayesedwa pa zokutira zomwe zimakonzedwa, kukhudzana ndi zotsukira kapena mankhwala. Mikhalidwe yokhazikika sinalembedwe. Chifukwa chake, wopanga ufa amakonza mkhalidwewo pokambirana ndi wogwiritsa ntchito kapena wogula womaliza.

Kuyesa kukana kwanyengo kwa zokutira zaufa ndikofunikira kwambiri pakuyika kwa ufa.
