2. Ihe Eco-Enyi na Enyi

   Basalt nkume bụ ihe okike. Usoro mmepụta ya anaghị ahapụ boron ma ọ bụ alkali metal oxides ndị ọzọ, n'ihi ya, uzuzu na anwụrụ ọkụ anaghị enwe ihe ndị na-emerụ ahụ ma ghara imetọ ikuku. Ngwaahịa ahụ nwekwara ogologo ndụ ogologo oge, na-eme ka ọ dị ọnụ ala, dị elu, na ihe ọhụrụ dị ọcha.

3. Okpomọkụ dị elu na mgbochi mmiri

   Na-aga n'ihu eriri basalt nwere ike ịrụ ọrụ na oke okpomọkụ nke -269°C ruo 700°C (na ebe nro dị nro nke 960°C). Nke a dị elu karịa geriri eriri (-60°C ruo 450°C) na eriri carbon (max 500°C). N'ụzọ doro anya, eriri basalt na-ejigide 80% nke ike mbụ ya mgbe ọ rụchara ọrụ na 600 Celsius ma ọ dịghị adalata na 860 Celsius. Ọ na-echekwa ike dị elu mgbe ekpughere ya na mmiri ọkụ 70 Celsius.

4. Ọkachamma kemịkalụ kwụsie ike na nguzogide corrosion

   Basalt fiber nwere ihe ndị dị ka K₂O, MgO, na TiO₂, nke na-eme ka ọ dịkwuo mma na-eguzogide ọgwụ corrosion na mmiri. Ọ kwụsiri ike na kemịkalụ karịa eriri iko, ọkachasị na mpaghara alkaline na acidic. eriri Basalt na-egosi ọbụna nguzogide alkali corrosion na ngwọta Ca (OH) ₂ zuru ezu na ciment.

5. Modul Elastic Elu na Ike Tensile

   Basalt fiber's elastic modulus (9100-11000 kg/mm) dị elu karịa nke E-glass fiber, asbestos, aramid, polypropylene, na silicon fibers. Ike ike ya (3800-4800 MPa) dị ukwuu karịa nke nnukwu-adọkpụ carbon fiber, aramid, fiber PBI, eriri ígwè, eriri boron, na eriri alumina, ma jiri ya tụnyere S-glass fiber. Site na njupụta nke 2.65-3.00 g/cm³ yana ike Mohs nke 5-9, ọ na-enye nkwụsi ike iyi dị mma na nkwado tensile. Ike n'ibu ya karịrị nke ebumpụta ụwa yana eriri sịntetịt, na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma.

6. Arụmọrụ mkpuchi ụda pụtara ìhè

   eriri basalt na-aga n'ihu nwere ezigbo ụda na ihe nnabata mkpọtụ. Ọnụ ọgụgụ nnabata ụda ya na-abawanye nke ukwuu na ugboro ole. Dịka ọmụmaatụ, ihe na-amịpụta ụda nke 1-3 μm dayameta basalt fibers (nke nwere njupụta nke 15 kg/m³ na ọkpụrụkpụ nke 30 mm) nwere ọnụọgụ absorption nke 0.05-0.15 na 100-300 Hz, 0.22-0.75 na 400,000 na 400-300. 1200-7000 Hz.

7. Njirimara Dielectric ama ama

   eriri basalt na-aga n'ihu's olu resistivity bụ usoro nke ịdị ukwuu dị elu karịa E-glass eriri, na-enye ya magburu onwe dielectric Njirimara. Ọ bụ ezie na nkume basalt nwere ihe fọrọ nke nta ka ọ bụrụ 0.2% conductive oxides, ọgwụgwọ elu pụrụ iche na ndị na-emepụta ihe nwere ike ibelata tangent dielectric site na 50% ma e jiri ya tụnyere eriri iko, na nkwụsị olu ya dịkwa elu.

8. Ndakọrịta Silicate eke

   Ọ na-agbasa nke ọma ma na-ejikọta ya na ciment na kọmpụta. Mgbasa ọkụ ya na ọnụọgụ nkwekọrịta na-agbanwe agbanwe, ọ nwekwara ezigbo nguzogide ihu igwe.

9. Mmụba mmiri dị ala

   eriri Basalt nwere ọnụego nnabata mmiri n'okpuru 0.1%, nke dị ala karịa eriri aramid, ajị anụ na asbestos.

10. Obere Thermal Conductivity

    Basalt fiber's thermal conductivity bụ 0.031-0.038 W / m·K, nke dị ala karịa eriri aramid, fiber silicate aluminum, fiber E-glass, ajị nkume, eriri silicon, eriri carbon, na igwe anaghị agba nchara.
