Kodayake ƙara antioxidants na iya inganta juriya na PP ga tsufa na oxiveative zuwa wani lokaci, hijirarsa, da kuma m, da kari, da kuma ƙari suna shafar rufin PP. Saboda haka, dogaro da antioxidants ne don inganta juriya na PP na tsufa ba zai iya haduwa da Life ba da amincinsa na DC Cable, na gaji cigaba kan gyaran PP.
3. Rufe aikin
Cajin sarari, a matsayin ɗayan waɗannan abubuwan da ke tasiri da ingancin da lifspan nahigh-voltage DC na USB, yana da matukar tasiri rarraba filin wutar lantarki na gida, ƙarfin mutucen likita, da kuma rufi abin tsufa. Abubuwan rufi na rufewa don murkushe cajin cajin sararin samaniya, rage allurar da aka caje ta hanyar hana karfin wutar lantarki a cikin rufi da kebulewa da kebulewa da kebul.
When DC cables remain in a unipolar electric field for an extended period, the electrons, ions, and impurity ionization generated at the electrode material within the insulation become space charges. Wadannan zargin da sauri suna ƙaura da tarawa cikin fakiti na cajin, wanda aka sani da tarin cajin sarari. Saboda haka, lokacin amfani da PP a cikin igiyoyi DC, gyare-gyare wajibi ne don ɗaukar ɗaukar ƙarni da kuma tara.
4. Hali na atisaye
Saboda mummunan aiki na zafi, zafin da aka samo a yayin aikin na igiyoyin DC da ke tsakanin rufin ciki da waje na rufi. Abubuwan da ke aiki da kayan polymer suna ƙaruwa da hauhawar yanayin zafi. Don haka, gefen bakin ciki na rufin da Layer Layer tare da ƙananan halayen ya zama zai iya yin cajin tarawa, yana haifar da rage girman filin lantarki. Haka kuma, yawan zafin jiki na haifar da allurar da hijirar da yawa na cajin sararin samaniya, kara gurbata filin lantarki. Babban zafin jiki da girma, mafi cajin cajin karin sarari ya faru, yana ƙaruwa da murabba'in filin lantarki. Kamar yadda aka tattauna a baya, babban zazzabi, cajin sararin samaniya, da kuma filin filin lantarki zai shafi aikin al'ada da rayuwar ta USBs na yau da kullun. Saboda haka, inganta halayen da PP ya zama dole don tabbatar da ingantaccen aiki da rayuwar sabis na DC na USBs.
