Kemikari yakagadzirwa basalt
Zvinonyatso zivikanwa kuti goko rePasi rinoumbwa nematombo egneous, sedimentary uye metamorphic.Basalt imhando yedombo rinopisa.Igneous rocks matombo anoumbwa apo magma anoputika pasi pevhu uye anonamira pamusoro.Igneous matombo ane anopfuura 65% SiO2matombo ane acidic, akadai segranite, uye ayo ane isingasviki 52% S0 anonzi matombo ekutanga, sebasalt.Pakati pezviviri pane matombo asina kwaakarerekera akadai seandesite.Pakati pezvikamu zvebasalt, zvinyorwa zveSiO2kazhinji iri pakati pe44% -52%, zvirimo muAl2O3iri pakati pe12% -18%, uye zvirimo zveFe0 neFe203iri pakati pe9% -14%.
Basalt irefractory mineral raw material ine tembiricha yakanyunguduka pamusoro pe1500 ℃.Iyo yakakwira iron yemukati inoita iyo fiber bronze, uye ine K2O, MgO uye TiO2iyo inoita basa rakakosha mukuvandudza kusapinda kwemvura uye kusaora kwefiber.
Basalt ore ndeye volcanic magma ore, iyo ine yakasikwa makemikari kugadzikana.Basalt ore chinhu chimwe chete-chikamu mbishi zvinhu zvekupfumisa, kunyungudika uye yunifomu mhando.Kusiyana nekugadzirwa kwegirazi fiber, basalt fiber kugadzira mbishi zvinhu zvakasikwa uye zvakagadzirira-zvakagadzirwa.
Mumakore achangopfuura, basa rakawanda rekutsvagisa rakaitwa kuvheneka ores akakodzera kugadzirwa kwekuenderera mberi basalt fiber raw materials, kunyanya kugadzirwa kwebasalt fibers ine hunhu hwakaiswa (senge simba remuchina, kemikari uye kugadzikana kwekupisa, kusungirirwa kwemagetsi; etc.), ores chaiwo anofanirwa kushandiswa Kemikari kuumbwa uye fiber kugadzira zvivakwa.Semuenzaniso: chiyero che ore chemikemikari inoshandiswa mukugadzirwa kwekuenderera mberi basalt fiber inoratidzwa mutafura.
| Kemikari yakagadzirwa | SiO2 | Al2O3 | Fe2O3 | CaO | MgO | TiO2 | Na2O | Dzimwe tsvina |
| Min% | 45 | 12 | 5 | 4 | 3 | 0.9 | 2.5 | 2.0 |

Zvisikwa zvakapa simba guru rekushandiswa kwebasalt ore.Pasi pemamiriro echisikigo, basalt ore inopfumisa, homogenization yemakemikari zvikamu uye kunyunguduka munzvimbo yakadzika yepasi.Kunyange zvisikwa zvinofunga kusundira basalt ore pamusoro penyika muchimiro chemakomo kuti ashandiswe nevanhu.Maererano nenhamba, inenge 1/3 yemakomo inoumbwa nebasalt.
Zvinoenderana nedatha yekuongorora yekemikari yebasalt ore, basalt raw materials inenge yakapoteredza nyika, uye mutengo i20 yuan/tani, uye mutengo wezvigadzirwa zvinogona kufuratirwa mumutengo wekugadzira basalt fiber.Kune nzvimbo dzemigodhi dzakakodzera kuenderera mberi basalt fiber kugadzirwa mumapurovhinzi mazhinji muChina, akadai se: ina, Heilongjiang, Yunnan, Zhejiang, Hubei, Hainan Island, Taiwan uye mamwe mapurovhinzi, mamwe ayo akagadzira inoenderera basalt fiber pamichina yekuyedza maindasitiri.Chinese basalt ores yakasiyana neEuropean ores.Kubva pakuona kwe geological, Chinese basalt ores "vadiki", uye havana hunhu hwakasiyana, ndiko kuti, izvo zvinonzi mavanga ekutanga ore.Kuburikidza nekuongororwa kwemapurovhinzi eChinese akadai seSichuan, Heilongjiang, Yunnan, Zhejiang, uye Hubei, kudzidza kwebasalt ores pakati nepakati nepakati peRwizi rwaYangtze, Hainan nemamwe matunhu kunoratidza kuti hapana dombo rekutanga mune aya basalt ores. , uye panongowanikwa mamwe mayero iron oxide akaturikidzana pamusoro.Izvi zvinobatsira kwazvo kuenderera mberi basalt fiber kugadzirwa, uye mutengo wezvinhu zvakasvibiswa uye mutengo wekugadzirisa wakaderera.
Basalt is anorganic silicate.Yakapfaviswa mumakomo anoputika uye muchoto, kubva pamatombo akaomarara kusvika kune akapfava, zvikero zvakareruka, uye mbariro dzakaoma.Nyaya yacho ine yakakwirira tembiricha kuramba (> 880C) uye yakaderera tembiricha kuramba (<-200C) , yakaderera thermal conductivity (kupisa kupisa), ruzha insulation, murazvo retardant, insulation, yakaderera mwando absorption, ngura kuramba, nemwaranzi kuramba, yakakwirira kutyora simba, yakadzika elongation, yakakwira elastic modulus, huremu huremu uye kumwe kuita kwakanakisa uye kuita kwakanakisa kugadzirisa, Ichinhu chitsva chose: haiburitse zvinhu zvine muchetura mukugadzirwa kwakajairwa nekugadzirisa, uye haina gasi remarara, tsvina yemvura, uye tsvina. kuburitswa kwezvisaririra, saka inodaidzwa kunzi kusvibiswa-isina "green industrial material and new material" muzana remakore rechi21.
Kuenzaniswa negirazi fiber, iyo inoshandiswa zvakanyanya mukuvaka, indasitiri yemakemikari uye mamwe maindasitiri, zviri pachena kuti basalt fiber uye zvigadzirwa zvayo zvinoumbwa zvine simba remagetsi, rakanaka remuviri uye makemikari zvinhu, uye rinogona kushandiswa kugadzira zvigadzirwa zvepamusoro.Zvichienzaniswa nezvimwe zvinhu, kushanda kwese kwezviviri kunofananidzwa.Zvimwe zvinhu zvebasalt fiber zviri nani pane kabhoni fiber, uye mutengo wayo uri pasi pechegumi checarbon fiber zvichienderana nemutengo wemusika uripo.Naizvozvo, basalt faibha faibha itsva ine mutengo wakaderera, kuita kwepamusoro uye kushambidzika kwakanaka mushure mecarbon fiber, aramid fiber uye polyethylene fiber.United States Texas Basalt Continuous Fiber Industry Alliance yakataura kuti: “Basalt continuous fiber inotsiva isingadhuri yecarbon fiber uye ine nhevedzano yezvinhu zvakanakisa.Kunyanya kukosha, nekuti inotorwa kubva kune yechisikigo ore isina chero yekuwedzera, ndiyo chete kusvibiswa kusiri kwezvakatipoteredza uye kusina chepfu.Carcinogenic girini uye ine hutano girazi fiber zvigadzirwa zvine yakakura musika kudiwa uye pre-application "
Basalt ore yakaiswa pamusoro penyika kwemamiriyoni emakore uye yakave iri pasi pezvakasiyana mamiriro ekunze.Basalt ore imwe yeakasimba silicate ores.Fiber dzakagadzirwa nebasalt dzine simba rechisikigo uye kugadzikana kunopesana nezvinosvibisa media.Yakasimba, yemagetsi insulating, basalt ore ndeye yakasikwa uye ine hushamwari nharaunda yakachena mbishi zvinhu.
