Fa'apitoa fa'atosina nitrogen mo alamanuia uaea

O le faʻaaogaina o mea faʻapipiʻi polyethylene faʻatasi ai ma sui faʻafesoʻotaʻi faʻapipiʻi peroxyide, o le taʻitaʻia o le talipupuni faʻamau, faʻamalama faʻapipiʻi, ma le puipui puipui puipui o loʻo faʻapipiʻiina e ala i le tolu-layer co extrusion, ona sosoo ai lea ma le faʻaauau ma tutusa le fesoʻotaʻi e ala i se faʻamau faʻamaufaʻailoga faʻamau faʻatumu i le vevela maualuga ma le maualuga o le kasa nitrogen. O le mea e fa'afefe ai le vevela o le ammonia gas (inert gas), ma le polyethylene e feso'ota'i fa'alava e lelei tele le eletise ma le gaosiga e o'o atu i le 500KV.
