Kulimbitsa xlpe chingwe ndi ma antioxidants

Udindo wa antioxidants popititsa patsogolo livelpan ya polyethylene (XLPE) zingwe zotsekemera

Cholumikizidwa ndi polyethylene (xlpe)ndi chiwonetsero choyambirira chogwiritsidwa ntchito mu zingwe zapakatikati komanso zamagetsi zazikulu. Nthawi yonse yonse ya ntchito zawo, aphunzitsiwa amakomana ndi zovuta zosiyanasiyana, kuphatikizapo nyengo yosiyanasiyana, kutentha kumasinthasintha, kupsinjika kwamakina, komanso mgwirizano wamankhwala. Zinthu izi mogwirizana zimakhudza kulimba mtima komanso kutaya mtima kwa zingwe.

Kufunikira kwa antioxidants mu xlpe kachitidwe

Kuonetsetsa moyo wambiri wa zingwe za Xlpe-insulated, kusankha antioxidant yovomerezeka kwa dongosolo la polyethylene ndikofunikira. Antioxidants amatenga gawo lofunika poteteza polyethylene kuwonongeka. Poyankha mwachangu ndi ma radicals aulere omwe amapangidwa mkati mwazinthuzi, ma antioxidants amapanga zinthu zambiri zokhazikika, monga hydroproroxide. Izi ndizofunikira kwambiri chifukwa njira zolumikizirana kwambiri za XLPE ndizokhazikika pa peroxide.

Njira yonyansa ya ma polima

Popita nthawi, ma poizo ambiri amakhala opanda phokoso chifukwa cha kuchepa kwa nthawi. Mapeto-amoyo a ma polima amafotokozedwa kuti ndi malo omwe gawo lawo litanyowa mpaka 50% ya mtengo woyambirira. Kupitilira pakhomo lako, ngakhale kugwada pang'ono za chingwe kungachititse kuti lizitha kusokonekera komanso kulephera. Miyezo Yapadziko Lonse nthawi zambiri imatengera lingaliro la ma polyyalefins, kuphatikizapo polyolefins otsekedwa, kuti awone kugwira ntchito.

Chizindikiro cha arrrinous cholosera kwa moyo

Chibwenzi Pakati pa kutentha ndi chingwe chokhazikika chimafotokoza pogwiritsa ntchito equation. Mtundu wa masamu uwu umafotokoza kuchuluka kwa mankhwala monga:

K = D e (-ea / rt)

Kuti:

K:

D: nthawi zonse

EA: Mphamvu Yoyambitsa

R: Boltzmann Gasivern pafupipafupi (8.617 x 10-5 EV / K)

T: Kutentha kwathunthu ku Kelvin (273+ temp mu ° C)

Anakonzanso algebilly, equation imatha kufotokozedwa ngati mawonekedwe a mzere: y = mx + b

Kuchokera pa equation iyi, mphamvu yoyambitsa (EA) imatha kugwiritsidwa ntchito pogwiritsa ntchito mawonekedwe amoyo, zomwe zimakuthandizani kulosera za moyo wabwino malinga ndi zinthu zosiyanasiyana.

Kuyeserera Kwakapitilira

Kuti mudziwe zingwe za XLpepen ya zingwe za Xlpe-zoyeserera ziyenera kuperekedwa kuti zitheke kuyesa kwa zaka zitatu (makamaka zinayi) matenthedwe. Kutentha kumeneku kuyenera kutalika kokwanira kukhazikitsa ubale wapakati pa nthawi yolephera ndi kutentha. Zoyenera, kutentha kotsika kwambiri kuyenera kuchititsa nthawi yayitali mpaka kumapeto kwa maola osachepera 5,000 kuonetsetsa kuti data.

Mwa kugwiritsa ntchito njira yolimbitsa thupiyi ndikusankha antioxidants apamwamba kwambiri, kudalirika kwa ntchito komanso kukhala ndi moyo wautali wa zingwe za Xlpe-zopangidwira kumatha kupitilizidwa kwambiri.
