Mhedzisiro yekusagadzikana basalt raw material kuumbwa pane chaiyo kugadzirwa uye kugadzirisa matanho

2025-06-20

Zvakafanana nekabhoni fiber uye Girazi Fiber, kugadzirwa kwekuenderera mberi basalt fiber kunoda mbishi zvinhu kumira. Pane misiyano yakakura mumhando uye mashandisiro ezvigadzirwa zvebasalt fiber zvigadzirwa kubva kumatunhu akasiyana. Kunyangwe mukati medunhu rimwe chete, misiyano iripo mubasalt kubva munzvimbo dzakasiyana dzemugodhi mumwechete.

Mukuita, matambudziko matatu makuru akaonekwa:

(1) Dzimwe basalt ore mbishi zvinhu zvine tembiricha yekudhirowa tembiricha, iri padyo zvakanyanya nekristaro tembiricha. Zvinhu zvakasvibirira zvakadaro zvinowanzoita kupenya pakarepo pakudhirowa, zvichiparadza kuenderera kwefiber uye kuderedza simba rekusimba.

(2) Mimwe basalt ore raw materials ine nhamba yakakwirira ye-high-temperature resistant crystalline particles, zvakadai se olivine uye corundum, zvichiita kuti zvive zvakaoma kuwana homogeneous melt.

(3) The Chemical kuumbwa kwezvimedu zvakasiyana-siyana zvebasalt ore mbishi zvinhu zvinosiyana, izvo zvinokanganisa kugadzikana kwekuita kwekuenderera mberi kwebasalt fibers inogadzirwa.

Kugadzirisa kusagadzikana kwekuumbwa kwezvinhu zvakasvibiswa, zvichibva pane zvataurwa pamusoro apa, matanho anotevera anogona kutorwa kuti avandudzwe:

Sarudza yakakwirira-mhando basalt ore mbishi zvinhu. Basalt ore inofanira kunge ine homogeneous, ine dhigirii yakaderera yecrystallization, isina phenocrysts yakakura, fissures shoma, kuderera kwemamiriro ekunze, uye pasina tsvina yekunze se quartz uye chert. Iko kemikari yebasalt ore inofanira kunge iri mukati mehutano hwakanaka. Pamusoro pezvo, inofanirwa kuve neyakakodzera acidity coefficient ( $M_{a}$ ) muchikamu che $3.5 \sim 5.8$ uye viscosity ( $l g kana$ ) ye $0.5 \sim 1.4 Zvakanaka \cdot s$ . Iyo viscosity ( $kana$ ) yesilicate melts ibasa rekushisa, kumanikidzwa, uye kuumbwa, uye inogona kumiririrwa neArrhenius equation: $l g kana = l g kana_{0} + UYE_{kana} / RT$ ,kupi $kana_{0}$ inogara iripo (pre-exponential factor) uye $UYE_{kana}$ ndiyo activation simba rekuyerera kwe viscous yekunyungudika. Basalt ore inofanirwa kuchengetedza tembiricha yakakura panguva yekudhirowa, iyo inoita kuti kunyunguduka uye kudhirowa kuve nyore, uye haifanirwe kunge iine yakakwira-tembiricha inodzivirira crystalline particles se olivine uye corundum.
Simbisa mbishi homogenization. Zvigadzirwa zvemhando yepamusoro zvinopwanywa, kuvhenekwa, uye kufananidzwa uchishandisa hunyanzvi midziyo isati yatumirwa kune pre-kiln silo. Kuve nechokwadi chemhando yeore mbishi zvinhu, saizi yechidimbu inofanirwa kuchengetedzwa zvakanyanya kuenderana. Zvimedu zvakakura zvakanyanya zvinogona kutungamira kumatambudziko ekunyunguduka, nepo zvidiki zvakawandisa zvinogona kuderedza kunaka kwekunyungudika.
Sanganisa emhando yepamusoro basalt ore mbishi zvinhu. Nekuda kwekuumbwa kwakaomarara kwechisikigo basalt ore, ine zvicherwa zvakasiyana-siyana zvine chekuita uye kugarisana, uye zvicherwa zvakasiyana zvine mapoinzi ekunyunguduka, ingave iyo mbishi yakazara homogeneous ndicho chimwe chezvinhu zvinosarudza zvinokanganisa mhedzisiro yekudhirowa. Kunyungudutsa zvirinani zvinhu uye kugadzirisa kugadzikana kwekuita kwefiber, mamwe mabhizinesi ekugadzira atora nzira ye "artificial batching", achikwereta kubva kugirazi fiber kugadzira. Izvi zvinosanganisira kugadzirira mbishi maererano nezviyero, kusarudza yepamusoro-soro yakachena yebasalt chaiyo, uye kuigadzirisa zvinoenderana neyakajairwa tsika uchishandisa "kupa chinoshaikwa" uye "chakachena kune chakachena" nzira - semuenzaniso, kuwedzera calcium kana isina kukwana. Pamusoro pezvo, kune zvigadzirwa zvine zvakakosha kuita zvinodiwa, yakasarudzika doping shanduko inogona kuitwa kuti ive nechokwadi chekuti zviratidzo zvese zvekushanda zvinosangana nezvinodiwa zvekugadzira, senge alkali-resistant fibers, high-temperature resistant fibers, uye yakakwirira-simba, yakakwirira-modulus fibers. Izvi zvinoda kusarudza inoenderana imwe-chikamu chicherwa zvicherwa kana mamwe basalt ores kune yakakodzera "doping modified" yeiyo yakachena basalt raw material.
