Maitiro eBoron Nitride Powder Kupa Mafuta Nguva Dzose Paunenge Uchipisa
Zvinhu Zvinokosha Zvaunofanira Kuziva
- Upfu hweBoron nitride hunopa mafuta akavimbika kana pakupisa kwakanyanya, kuchengetedza kushanda kusvika 3000 °C munzvimbo dzine nitrogen.
- Zvayo chiyero chekukweshana kwakaderera inoderedza kupera kwemuchina, zvichiita kuti mashandiro acho ave nyore uye kuti michina igare kwenguva refu.
- Kusashanda zvakanaka kwemakemikari eBoron nitride kunoita kuti ikwanise kuramba makemikari ane simba, zvichiita kuti ive yakakodzera kushandiswa pakupisa kwakanyanya mumaindasitiri akasiyana-siyana.
Nei Boron Nitride Inoshandiswa Zvakanyanya MuMasisitimu Emafuta Anopisa Nekupisa Kwakanyanya
Maumbirwo uye Kuramba Kupisa kweBoron Nitride Powder
Unogona kuvimba neupfu hwe boron nitride kuti hurambe hwakaita kunyangwe kana hwakaiswa pakupisa kwakanyanya. Chimiro chehexagonal, chinowanzonzi "white graphite," chinopa chimiro chakasimba uye chakasimba. Chimiro ichi chinobatsira upfu kuti husaputsike pakupisa kwakanyanya. Unoona izvi mukukwanisa kwahwo kubata kupisa kusvika 3000 °C mumhepo ine nitrogen uye kusvika 2000 °C mumamiriro ekunze asina kusimba. Upfu hwacho hunoenderanawo ne quartz mukuwedzera kwekupisa asi hune thermal conductivity yakapetwa kagumi. Izvi zvinoreva kuti hunoparadzira kupisa nekukurumidza uye zvakaenzana, izvo zvinodzivirira michina yako kubva pakupisa zvakanyanya.
Heino tafura inoratidza kuti boron nitride powder inosiyana sei mukudzivirira kupisa uye hunhu hwekupisa:
| Pfuma | Kukosha |
|---|---|
| Kufambisa kwekupisa | Yakapetwa kagumi kupfuura quartz |
| Kudzivirira kupisa mu nitrogen | Kusvika ku3000 °C |
| Kudzivirira kupisa mune zvisina kwazvakarerekera | Kusvika 2000 °C |
| Kudzivirira kupisa mu argon | Kusvika 2800 °C |
| Kusashanda kwemakemikari | Zvinenge zvese simbi dzakanyungudutswa |
| Chiyero chekuwedzera | Yakaenzana nequartz |
Unogona kuona kuti nei boron nitride iri inoshandiswa zvakanyanya mukupisa kwakanyanya masisitimu ekuzora mafuta. Maumbirwo ayo uye kuramba kwayo kupisa kunoita kuti ive sarudzo yepamusoro yemabasa akaoma.
Kutsanangurwa kweKusagadzikana Kwemakemikari uye Kusagadzikana Kwemakemikari
Kana ukashandisa upfu hwe boron nitride, unowana chinhu chinotsvedza nyore nyore uye chisingashande nemakemikari mazhinji. Upfu hwacho hune hunyanzvi hwakaderera hwekukweshana, zvinoreva kuti zvikamu zvinofamba zvinotsvedza zvakanaka pamusoro pechimwe nechimwe. Izvi zvinobatsira kuderedza kupera kwemuchina wako. Kunyangwe pakupisa kwakakwira kusvika 1000 °C munzvimbo dzinopisa, boron nitride inochengetedza simba rayo rekuzora.
Boron nitride inoshandiswa zvakanyanya muma lubricant systems anodziya zvakanyanya nekuti inogara yakasimba uye haisangani nemakemikari ane simba. Heano mamwe mashoko nezvemaitiro ayo emakemikari:
- Upfu hweBoron nitride hunoratidza kugadzikana kwakanyanya kwemakemikari.
- Hainyorovese simbi dzakawanda dzakanyungudutswa nemagirazi.
- Inoramba yakasimba kunyangwe kana ikasangana nezvinhu zvakawanda zvine hukasha.
- Maumbirwo ayo akasiyana uye kuwanda kwayo zvinoita kuti ive inobatsira mumaindasitiri akawanda.
- Inouya mumhando dzakasiyana-siyana, dzakadai sehexagonal, cubic, uye wurtzite, izvo zvinobatsira kuti ishande zvakanaka munzvimbo dzakaoma.
Unogona kuvimba ne boron nitride kuti michina yako irambe ichishanda zvakanaka, kunyangwe zvimwe zvinhu zvikatadza kushanda.
Kuenzanisa neMafuta Echinyakare
Ungashamisika kuti boron nitride inokwanisa sei inoenzaniswa nemamwe mafuta ekuzora se graphite kana molybdenum disulfide. Boron nitride inoshandiswa zvakanyanya muma lubricant systems anodziya zvakanyanya nekuti inoshanda kupfuura idzi nzira dzechinyakare nenzira dzakasiyana-siyana.
- Hexagonal boron nitride (h-BN) inoramba ichishanda kusvika 800 °C munzvimbo dzinoita kuti oxygen ioxidize, ukuwo molybdenum disulfide ichikurumidza kupera.
- Mafuta eBoron nitride anogona kubata tembiricha inosvika 1200 °C mumamiriro ekupisa, akakwirira kupfuura graphite kana molybdenum disulfide.
- Mafuta eHBN anodzivirira oxidation uye kupisa, saka anogara kwenguva refu munzvimbo dzinopisa.
- Graphite inorasikirwa nekushanda kwayo kana tembiricha yakakwira nekuti inonyungudika nyore nyore.
Kana uchida mafuta anogona kubata kupisa, kudzivirira makemikari, uye kuramba achishanda pasi pekumanikidzwa, boron nitride inoshandiswa zvakanyanya mumasisitimu ekuzora mafuta anodziya zvakanyanya nekuda kwechikonzero. Inokupa mashandiro akavimbika uko mamwe mafuta asingakwanise.
Mashandisirwo Enyika Chaiyo uye Mashandisirwo Anoshanda
Mashandisirwo Emaindasitiri Munzvimbo Dzinopisa Zvikuru
Uchawana boron nitride powder mumaindasitiri akawanda anoda mafuta akavimbika pakupisa kwakanyanyaHunhu hwayo hwakasiyana hunoita kuti ive sarudzo yepamusoro kune mabasa akaoma. Unogona kuona mashandisirwo anoitwa boron nitride powder patafura iri pazasi:

| Kugadziriswa kweGirazi/Ceramic | Inoshanda semushonga wekusunungura chakuvhuvhu, ichideredza kupera kwesimbi uye ichidzivirira kunamira panguva yekushanda kwekupisa kwakanyanya. |
Uchaonawo hupfu hwe boron nitride mundege nekudzivirira. Hunodzivirira dziviriro yekupisa, maburi e nozzle, uye hunonyorovesa injini dzeroketi nemasatellite. Mukugadzirisa simbi, hunoshanda sechinhu chinosunungura mukugadzira uye hunobatsira kuderedza kukweshana nekusakara mukugadzira.
Boron Nitride inoshandiswa zvakanyanya mumasisitimu ekuzora anodziya zvakanyanya nekuti inopa kugadzikana kwakanyanya kwekupisa, kukweshana kushoma, uye kusashanda kwemakemikari. Hunhu uhwu hunobatsira kuwedzera hupenyu hwemidziyo yako. Kana ukashandisa boron nitride coatings, unowana:
- Kudzivirira kupisa kwakanyanya munzvimbo dzakanyanya
- Mafuta epamusoro-soro uye asinganyorovese zvinoderedza kukweshana nekupfekwa
- Dziviriro kubva mukuora uye oxidation
Nzira dzeKugadzira uye dzeKushandisa
Unogona kushandisa boron nitride powder nenzira dzakawanda kuti uwane mafuta akanakisa. Nzira chaiyo uye nzira inobatsira kuti uwane kufukidza kwakaenzana uye kushanda kwenguva refu. Tafura iri pazasi inoratidza mhando dzekuzadza dzakajairika uye zviyero zvadzo zvinokurudzirwa:
| Rudzi rwekuzadza | Chikamu Chevhoriyamu (vhoriyamu%) | Hunhu |
|---|---|---|
| Hexagonal Boron Nitride (h-BN) | 2–20 | Inowedzera kufambiswa kwekupisa uye inoderedza viscosity kana ikabatanidzwa ne spherical fillers. |
| Alumina yakatenderera (Al₂O₃) | 2–20 | Inozadza nzvimbo dziri pakati penzvimbo, ichivandudza huwandu hwezvinhu zvinoiswa uye nzira dzinoshandiswa pakupisa. |
Unogona kushandisa upfu hwe boron nitride uchishandisa nzira dzakasiyana siyana:
| Maitiro | Tsananguro |
|---|---|
| Kubatanidzwa muComposites | Wedzera boron nitride pazvinhu zvakasanganiswa kuti uwedzere mafuta uye kuderedza kukweshana nekupfekwa. Izvi zvinoshanda zvakanaka muzvinhu zvakasanganiswa zvepolymer, simbi, uye ceramic. |
| Kugadziriswa Kwepamusoro | Shandisa mishonga yekubatanidza makemikari kana kurapa neplasma kuti boron nitride ipararire zvakaenzana uye ishande zviri nani mumafuta ekuzora. |
| Kugadzirisa Zvidimbu | Gadzirisa saizi yezvikamu uye chimiro. Zvikamu zveNanoscale zvinowanzokupa mafuta akanakisisa. |
Zano: Kuti uwane mhedzisiro yakanaka, sarudza saizi yezvikamu uye chiyero chemusanganiswa chakakodzera chekushandisa kwako. Chengeta upfu hweboron nitride yako munzvimbo inotonhorera, yakaoma kuti igare iri mumamiriro akanaka.
Kukunda Matambudziko Akajairika Ekushandisa Mafuta
Nzvimbo dzinopisa zvakanyanya dzinokonzera matambudziko akawanda ekuzora mafuta. Unogona kusangana nekukweshana, kukweshana, uye zvikanganiso pamusoro, kunyanya panguva yekuita senge superplastic kugadzira aruminiyamu. Kukweshana kunoitika kana nzvimbo dzakanamirana pamwe chete uye dzichikonzera kukuvara.
Upfu hweBoron nitride hunokubatsira kugadzirisa matambudziko aya. Hunoshanda sechidziviriro chakasimba pakati penzvimbo, hunoderedza kukweshana uye hunodzivirira kukora kunyangwe pakupisa kusvika ku800°C (1472°F). Unowana mashandiro akapfava uye zvikanganiso zvishoma.
- Inoderedza kukweshana kwepakati pesimbi
- Inodzivirira marwadzo uye kukuvara kwenzvimbo
- Inoita kuti michina irambe ichishanda kwenguva yakareba kana kuchipisa zvakanyanya
Kana ukashandisa upfu hweboron nitride, unogona kuvimba nemichina yako kuti ishande zviri nani uye inogara kwenguva refu. Boron Nitride inoshandiswa zvakanyanya mumasisitimu ekuzora mafuta anodziya zvakanyanya nekuti inogadzirisa matambudziko asingakwanise kugadziriswa nezvimwe zvinhu.
Unogona kuvimba nehupfu hweboron nitride kuti huchengetedze michina ichishanda zvakanaka, kunyangwe pakupisa kwakanyanya. Hunhu hwayo hwakasiyana nehwemafuta echinyakare.
