1. uaea apamemea:

O le faʻaaogaina o le kopa eletise e pei o mea mata, o le uaea apamemea e faia e ala i le faʻaauauina o le lafoina ma le taʻavale o loʻo taʻua o le uaea apamemea maualalo.Ua ta'ua le uaea apamemea e leai se okesene.

Low okesene uaea apamemea okesene mea i totonu o le 100 ~ 250ppm, apamemea anotusi o 99.9 ~ 9.95%, conductivity o 100 ~ 101%.

Oxygen free apamemea uaea okesene anotusi o 4 ~ 20ppm, apamemea anotusi o 99.96 ~ 9.99%, conductivity o 102%.

Ole mamafa fa'apitoa ole kopa ole 8.9g/cm3.

2. Uaea alumini:

O le uaea alumini o loʻo faʻaaogaina mo le uaea eletise e faʻafefe ma faʻamaluluina.Uaea alumini fa'aaogaina mo uaea e le masani ona fa'amaluluina.

Ole malosi ole eletise ole alumini fa'aoga mo uaea ma uaea e tatau ona 0.028264 ω.Mm2 / m, ma le mamafa patino o le alumini e tatau ona 2.703g/cm3.

3. Polyvinyl chloride (PVC)

Polyvinyl chloride palasitika e faʻavae i luga o le polyvinyl chloride resin, faʻaopoopoina le tele o mea faʻamaopoopo faʻafefiloi, e pei o le anti-aging agent, antioxidant, filler, brightener, flame retardant, ma isi, o lona mamafa e tusa ma le 1.38 ~ 1.46g / cm3.

Uiga o mea PVC:

Mea fa'ainisinia sili ona lelei, vaila'au fa'aleaga, le fa'amumu, lelei le tau, fa'amalo lelei eletise, faigofie gaioiga, ma isi.

Le lelei o mea PVC:

(1) pe a mu, e tele le asu oona e alu;

(2) Le lelei le fa'atinoina o le soifua matua.

O le PVC o loʻo i ai mea faʻapipiʻi ma mea faʻapipiʻi.

4.PE:

O le polyethylene e faia i le ethylene polymerization, e tusa ai ma le mamafa e mafai ona vaevaeina i le polyethylene maualalo (LDPE), polyethylene medium density (MDPE), polyethylene maualuga (HDPE).

Ole maualuga ole polyethylene maualalo maualalo ole 0.91-0.925 g / cm3.Ole maualuga ole polyethylene medium density ole 0.925-0.94 g/cm3.Ole maualuga ole hdPE ole 0.94-0.97 g/cm3.

Tulaga lelei o mea polyethylene:

(1) Tete'e fa'a'ese'ese maualuga ma tete'e voltage;

(2) I le tele o laina fa'alava, o le dielectric tumau ε ma le dielectric gau Angle tangent tgδ e laiti;

(3) fetuutuunai, lelei le ofuina;

④ Lelei vevela matua tetee, maualalo le vevela faatinoga ma mautu vailaau;

⑤ Lelei le faʻafefe o le vai ma le maualalo o le susu;

⑥ O le uaea na faia i ai e mama i le lelei ma faigofie i le faʻaogaina ma le faʻapipiʻiina.

Le lelei o mea polyethylene:

Faigofie e mu pe a faʻafesoʻotaʻi ma le afi;

E maualalo le vevela fa'amalulu.
