Basalt fiber yog cov khoom siv fiber ntau ua los ntawm pob zeb basalt nrog kev kho tshwj xeeb. Nws muaj lub zog siab, hluav taws kub thiab corrosion kuj thiab yog dav siv hauv kev tsim kho, aerospace thiab tsheb tsim. Txhawm rau kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm basalt fibers, cov qauv ntawm cov basalt fibers tau tsim.

1. Cov txheej txheem rau lub cev muaj zog ntawmbasalt fibers
Cov cuab yeej cuab tam tus qauv ntawm basalt fiber yog ib qho tseem ceeb indexes los ntsuas nws qhov zoo. Nws feem ntau suav nrog txoj kab uas hla, fiber ntau ntev, fiber ntau ntom, tensile zog, elongation thaum so thiab lwm yam. Fiber txoj kab uas hla cuam tshuam qhov yooj thiab lub zog ntawm fiber, fiber ntev ncaj qha cuam tshuam rau nws daim ntawv thov ntau thiab kev ua haujlwm. Fiber density cuam tshuam rau thermal conductivity thiab hluav taws kub tsis kam ntawm cov khoom. Lub zog tensile thiab elongation ntawm kev tawg qhia txog tensile thiab ductile zog ntawm fiber.
2. Cov txheej txheem tshuaj lom neeg rau basalt fibers
Cov cuab yeej cuab tam tus qauv ntawm basalt fiber ntau yog lub hauv paus tseem ceeb los xyuas kom meej nws cov corrosion kuj thiab ib puag ncig tus phooj ywg. Feem ntau suav nrog cov tshuaj fiber ntau, fiber ntau impurity cov ntsiab lus, fiber ntau solubility, fiber ntau toughness. Fiber tshuaj muaj pes tsawg leeg ncaj qha txiav txim siab nws cov kua qaub thiab alkali corrosion kuj thiab thermal stability impurity cov ntsiab lus nyob rau hauv lub fiber muaj ib qho tseem ceeb cuam tshuam rau lub mechanical zog thiab kev ua tau zoo ntawm cov fiber. Fiber solubility yog qhov taw qhia tseem ceeb los ntsuas qhov ruaj khov thiab solubility ntawm fiber. Fiber toughness qhia txog cov yam ntxwv tawg thiab durability ntawm fiber.

3. Cov txheej txheem rau thermal zog ntawm basalt fibers
Cov txheej txheem thermal khoom ntawmbasalt fibersyog lub hauv paus tseem ceeb rau kev ntsuam xyuas lawv cov refractory thiab thermal conductivity zog.
Nws feem ntau suav nrog fiber ntau kub ua haujlwm ua haujlwm, fiber ntau thermal conductivity, fiber ntau thermal expansion coefficient thiab lwm yam. Lub fiber ntau kub kuj ua tau zoo txiav txim siab nws stability thiab kev nyab xeeb nyob rau hauv qhov kub thiab txias ib puag ncig. Fiber thermal conductivity ncaj qha cuam tshuam rau cov khoom siv thermal rwb thaiv tsev kev ua haujlwm thiab kev txuag hluav taws xob. Cov fiber ntau thermal expansion coefficient, ntawm qhov tod tes, muaj qhov cuam tshuam tseem ceeb ntawm thermal thiab seem stability ntawm fiber.
4. Cov txheej txheem kev ua haujlwm ib puag ncig rau basalt fibers
Cov txheej txheem kev ua haujlwm ib puag ncig ntawm basalt fibers yog ib qho tseem ceeb siv rau kev ntsuam xyuas lawv qhov cuam tshuam rau tib neeg kev noj qab haus huv thiab ib puag ncig. Feem ntau suav nrog cov ntsiab lus ntawm cov khoom tsis zoo hauv fiber ntau, fiber ntau tso tawm degree, fiber ntau bio-persistence thiab lwm yam. Cov ntsiab lus ntawm cov khoom phom sij hauv fibers muaj qhov cuam tshuam tseem ceeb rau kev tsis muaj mob thiab ib puag ncig tus phooj ywg ntawm fibers. Fiber tso tawm degree yog ib qho tseem ceeb qhia rau kev soj ntsuam cov degree ntawm kev tso tawm thiab diffusion ntawm fibers. Fiber bio-persistence qhia txog qhov decomposition thiab degradation ceev ntawm fibers hauv ib puag ncig ntuj.
Kev tsim thiab siv cov qauv basalt fiber ntau yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov khoom siv fiber ntau. Tsuas yog nyob rau hauv nruj raws li tus qauv yuav tsum tau rau ntau lawm thiab kuaj, thiaj li yuav xyuas kom meej daim ntawv thov ntawmbasalt fiber ntaunyob rau hauv ntau yam kev cuam tshuam thiab kev ntseeg tau. Nyob rau tib lub sijhawm, ntxiv dag zog rau basalt fiber ntau cov qauv kev tshawb fawb thiab hloov tshiab, yuav pab kom tsis tu ncua kev txhim kho kev ua haujlwm thiab kev siv cov basalt fiber ntau, txhawb kev txhim kho thiab kev vam meej ntawm cov lag luam muaj feem xyuam.
