Nā Mea Hana Uila Mana: Alakaʻi Koho no ka PE Pale Ahi, PP Pale Wela, a me ka ABS Pale Ahi

I ka hana ʻana o ke kaula mana, pili pololei ke koho ʻana i nā mea i ka palekana uila, ka ikaika mechanical, a me ke ola lawelawe. ʻO PE, PP, a me ABS nā mea ʻekolu i hoʻohana nui ʻia. Hoʻohana nui ʻia ʻo PE a me PP no ka insulation wire a me ka sheathing, ʻoiai ʻo ABS ka mea i hoʻohana nui ʻia no nā plugs a me nā hale.

I. PE (Polyethylene)
PEHe mea hoʻomehana uea maʻamau me ka hoʻomehana uila maikaʻi loa, ka maʻalahi maikaʻi, ke kū'ē ʻana i ka mahana haʻahaʻa, a me ka omo wai haʻahaʻa loa. He kūpono ia no ka hoʻohana lōʻihi mai -40°C a i 80°C, e kūpono ai no ka hoʻomehana ʻana o loko o ke kaula mana. ʻAʻole pale ahi ka PE maʻamau (ʻōkuhi oxygen 17-18) a pono e hoʻololi i ka pale ahi (e laʻa, me ka magnesium hydroxide a i ʻole ka alumini hydroxide) e hoʻokō i nā kūlana palekana. Hoʻohana ʻia ʻo PE no nā papa hoʻomehana i loko o nā kaula mana, nā uea uila, a me nā kaula ʻikepili, a hiki ke lawelawe pū ma ke ʻano he uhi uea māmā. ʻAʻole hoʻohana pinepine ʻia no nā hale plug.

II. PP (Polypropylene)
ʻOi aku ka maikaʻi o PP ma mua o PE i ke kūpaʻa wela a me ka ikaika mechanical. Loaʻa i nā papa i hoʻololi ʻia nā mahana hana lōʻihi o 100°C a i 105°C, me ke kūpaʻa flex maikaʻi loa, ke kūpaʻa luhi, a me ke kūpaʻa kemika. He kūpono loa ʻo PP no nā uea uila, nā harnesses wiring, a me nā kaula mana wela waena a kiʻekiʻe e koi ana i ke kūpaʻa wela kiʻekiʻe a me ka lōʻihi. E like me PE, hoʻohana nui ʻia ʻo PP no nā noi uea. ʻOi aku ka haʻahaʻa o kona paʻakikī a me ka ikaika hopena ma mua o ABS, a ʻo kona emi ʻana o ka mold kiʻekiʻe e hoʻolilo iā ia i mea kūpono ʻole no nā hale plug.

III. ABS
He palakika ʻenekinia ʻo ABS no nā plug a me nā hale o ke kaula mana. Hoʻohui ia i ka paʻakikī, ke kūpaʻa i ka hopena, ke kūpaʻa o ka dimensional, a me ka ʻōlinolino maikaʻi loa o ka ʻili, me ka hiki ke hana ʻia ke hoʻoheheʻe ʻia ʻana o ka injection. He lapalapa ka ABS maʻamau (ʻo ka helu oxygen ma kahi o 18), no laila pono ka ABS flame-retardant e hālāwai ana me nā helu UL 94 V-0 a i ʻole V-2 no nā noi kaula mana. ʻAʻole kūpono ka ABS no ka insulation wire a hoʻohana wale ʻia no nā ʻāpana palakika o waho.

IV. Nā Manaʻo Koho
PE: No nā papa insulation i loko o nā kaula mana, nā uea uila, a me nā kaula ʻikepili e pono ai ka hana insulation kiʻekiʻe a me ka maʻalahi. Pono e hoʻohana ʻia ka PE i hoʻololi ʻia me ka pale ahi.
PP: No nā uea uila, nā kāʻei uea, a me nā kaula mana wela waena a kiʻekiʻe e koi ana i ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa flex.
ABS Pale Ahi: No nā plug, nā hale adapter, nā ʻūmiʻi kaula, a me nā ʻāpana kūkulu ʻē aʻe. Koho i ka ABS e kū nei i nā helu pale ahi UL 94.
ʻO ke koho pono ʻana i nā mea e hōʻoiaʻiʻo ai i ka palekana kūpono, ka lōʻihi, a me ke ʻano no nā kaula mana.

Hopena
HONUA HOʻOKAHIloea i ka hāʻawi ʻana i ka PE i hoʻololi ʻia me ka pale ahi, PP pale wela, a me ka ABS pale ahi no nā noi kaula mana, e hāʻawi ana i nā hoʻonā i hana kūikawā ʻia a me ke kākoʻo loea. No ka ʻōlelo aʻoaʻo koho, hoʻāʻo laʻana, a i ʻole nā ​​​​​​ʻōlelo kūʻai, e ʻoluʻolu e kelepona mai iā mākou.
