Kedu ka ịdị n'otu nke ịfụfụ na ngwaahịa mkpuchi rọba-plastic si emetụta arụmọrụ mkpuchi ha?

1. Ịgba Ụfụ n'Uwe: Na-eme ka arụ ọrụ mkpuchi kachasị mma

Mgbe ụfụfụ bụ otu, obere, kesaa nke ukwuu, yana egosipụtara ụdị nha nha n'ime ngwaahịa ahụ. Afụ ndị a na-egbochi nnyefe okpomọkụ nke ọma:

• Ikuku ikuku dị n'ime obere afụ ndị a kpuchiri ekpuchi dị oke ala, na-ebelata mbufe ọkụ convection.
• Ọdịdị afụ nke otu ahụ na-egbochi okpomọkụ ịbanye site na ebe adịghị ike, na-akpụ ihe mgbochi mkpuchi na-aga n'ihu ma kwụsie ike.

Nke a na-edobe a ala mkpokọta thermal conductivity (nke a, thermal conductivity nke ruru eru rubber-plastic ikpuchi ihe bụ ≤0.034 W / (m·K)), si otú a nweta ezigbo mkpuchi.

2. Ụfụfụ na-enweghị isi: Na-ebelata arụmọrụ mkpuchi nke ọma

Ọfụfụ na-ezighi ezi (dị ka nnukwu ọdịiche dị na nha afụ, mpaghara na-enweghị afụ, ma ọ bụ afụ gbajiri / jikọtara) nwere ike imebi ihe mkpuchi mkpuchi ozugbo, na-eduga n'ibelata arụmọrụ mkpuchi. Okwu ndị akọwapụtara gụnyere:

• Mpaghara Okpokoro Mpaghara (Mba/Afụ dị ala): Oke ebe enweghị afụ mkpuchi. Thermal conductivity nke rubber-plastic matrix n'onwe ya dị elu karịa nke ikuku, na-emepụta "ọwa ọkụ" nke na-ebufe ọkụ ngwa ngwa ma mepụta "mpaghara nwụrụ anwụ."
• Bubbles buru ibu/jikọrọ: Afụ nke ukwuu na-adịkarị mfe ịgbawa, ma ọ bụ ọtụtụ afụ na-ejikọta iji mepụta "ọwa ikuku ikuku." Ikuku ikuku dị n'ime ọwa ndị a na-eme ka mgbanwe okpomọkụ dịkwuo elu ma na-abawanye n'ozuzu ikpo ọkụ ọkụ.
• N'ozuzu arụmọrụ anaghị akwụsi ike: Ọbụlagodi na a na-anabata ụfụfụ na mpaghara ụfọdụ, usoro na-ezighi ezi nwere ike ime ka mgbanwe dị na arụmọrụ mkpuchi nke ngwaahịa ahụ n'ozuzu ya, na-eme ka ọ ghara iru ihe mkpuchi mkpuchi kwụsiri ike. Ka oge na-aga, usoro afụ ahụ na-ekwekọghị ekwekọ nwere ike ime ka ịka nká dịkwuo elu, na-eme ka mmebi mkpuchi ka njọ.
