Leqephe la Polyethylene e Phahameng ka ho Fetisisa (HDPE/PE300)
Tlhaloso:
Letlapa la polyethylene PE300 - HDPE ke polasetiki e bobebe le e matla ea boenjiniere e nang le tšusumetso e matla. E boetse e na le khanyetso e ntle ea lik'hemik'hale e nang le mongobo o tlase haholo mme e amohetsoe ke FDA. HDPE e ka boela ea etsoa le ho chesetsoa. Letlapa la polyethylene PE300.
Lintlha tsa Bohlokoa :
E etselitsoe hore e be e 'ngoe ea lipolasetiki tse sebetsang ka ho fetisisa lefatšeng, polyethylene e phahameng e fana ka mefuta e mengata ea melemo. HDPE ea rona e etselitsoe ho tšoarella nako e telele, tlhokomelo e tlase le e sireletsehileng. Thepa ke FDA e lumelletsoeng hore e sebelisoe indastering ea ho lokisa lijo, 'me e fana ka melemo e meng ea ho ba mongobo, letheba le ho hanyetsa monko.
Ntle le melemo e mengata e thathamisitsoeng ka holimo, HDPE ha e na kutu, ho bolelang hore ha e qhekelle, ha e bola, kapa ha e boloke libaktheria tse kotsi. Tšobotsi ena ea bohlokoa, hammoho le ho hanyetsa boemo ba leholimo, e etsa hore HDPE e be e loketseng ho sebelisoa libakeng tse nang le metsi, lik'hemik'hale, lihlapolli le maro a mang.
HDPE e boetse e tsejoa ka hore e na le matla a maholo ho karo-karolelano ea boima ba 'mele (ho tloha ho 0.96 ho isa ho 0.98 g), leha ho le joalo e qhibiliha habonolo ebile e bōptjoa. E ka sehoa habonolo, ea etsoa ka mochini, ea etsoa, ea tšeloa le/kapa ea fasoa ka mochini ho fihlela litlhoko tse batloang tsa lits'ebetso tse se nang palo.
Qetellong, joalo ka lipolasetiki tse ngata tse entsoeng ka boenjiniere, HDPE e ka sebelisoa habonolo hape e ka thusa haholo ho fokotsa litšila le tlhahiso ea polasetiki.
