Gukoresha ifu ya Hexagonal Boron Nitride mu mavuta ugomba kugerageza muri uyu mwaka

Ibintu by'ingenzi byakunzwe

• Ifu ya nitride ya boron nitride ifite ibara rya hexagonal yongera imikorere y'amavuta yo kwisiga mu kugabanya gukururana no kunoza uburyo bwo kudashira, bigatuma iba nziza cyane mu gukoresha ubushyuhe bwinshi.
• Guhitamo urwego rukwiye n'ingano y'uduce Ifu ya BN ni ingenzi cyane mu gutuma amavuta aryoshye; ifu nziza cyane ikora neza mu mirimo ijyanye n'ubuziranenge, mu gihe uduce duto dukwiriye gukoreshwa mu bushyuhe bwinshi.
• Gukoresha ifu ya 1% BN mu mavuta bitanga uburinganire bwiza mu mikorere no mu buryo buhamye, bigatuma habaho igihe kirekire cyo kuyikoresha no kugabanya ikiguzi cyo kuyitunganya.

Gukoresha ifu ya Hexagonal Boron Nitride mu mavuta: Ibyiza n'Imiterere y'ingenzi

Ifu ya Hexagonal Boron Nitride ni iki?

Ushobora kuba uzi ifu ya boron nitride ifite impande esheshatu nka 'grafiti yera'. Iyi fatizo igizwe na atome za boron na azote zitondetse mu byiciro. Imiterere yayo ituma ifu inyerera byoroshye, bigatuma iba nziza cyane mu gusiga amavuta. Ushobora kuyisanga mu nganda nyinshi kuko irwanya ubushyuhe n'imiti. Gukoresha ifu ya boron nitride ifite impande esheshatu mu gusiga amavuta bikoresha iyi miterere kugira ngo binoze imikorere mu bidukikije bikenera imbaraga nyinshi.

Imiterere y'ingenzi yo gusiga amavuta

Ifu ya boron nitride ifite ibara rya hexagonal iratandukanye cyane kubera imiterere yayo yihariye y’umubiri n’imiti. Urashobora kubona uburyo iyi miterere ishyigikira amavuta mu mbonerahamwe iri hepfo:

Ibyiza by'ingenzi mu gukoresha amavuta yo kwisiga

Ubona inyungu nyinshi iyo ukoresheje ifu ya boron nitride ifite impande esheshatu mu mavuta. Uburyo bwo gukoresha ifu ya boron nitride ifite impande esheshatu mu mavuta butanga:

• Ubudahangarwa bukomeye ku isuku n'igabanuka ry'ubushyuhe, ni byiza cyane mu gukoresha mu bushyuhe bwinshi.
• Guhuza imiti n'ibintu byinshi bitandukanye na grafiti ishobora kugabanya ubushyuhe.
• Kugabanya neza uburyaryate mu bihe byumye n'iby'ubushuhe.
• Amavuta aramba yinjira mu mwenge w'icyuma.
• Ahantu hasukuye hadafite ibisigazwa byinshi n'ibyuma byinshi.

Ushobora kwishingikiriza ku ifu ya boron nitride ifite impande esheshatu kugira ngo igumane ubushyuhe bugera kuri 1000°C mu kirere na 1800°C mu mwuka udafite umwuka. Gukoresha ubushyuhe binoza kuziba no kudakoresha imiti, bigatuma iba amahitamo meza ku mirimo ikomeye.

Uburyo bwo gukoresha ifu ya BN mu mavuta: Uburyo, Igipimo, n'inama z'ingirakamaro

Guhitamo ifu ikwiye ya BN (Ingano n'ingano y'uduce)

Ugomba guhitamo ubwoko bukwiye n'ingano ikwiye y'ifu ya boron nitride ifite impande esheshatu. Gukoresha ifu ya Hexagonal Boron Nitride Mu mavuta yo kwisiga biterwa no guhuza ifu n'ibyo ukeneye byihariye. Ifu nziza cyane ikora neza mu mirimo yo gutunganya neza, mu gihe uduce duto dukwiriye gukoreshwa mu bushyuhe bwinshi. Imbonerahamwe iri hepfo igaragaza imiterere isanzwe n'ikoreshwa ryabyo:

Ifu nto, zingana na µm 1 na µm 25, zigira filime zikomeye kandi zigumana amavuta nubwo byaba bigoye. Ifu nto, ziri munsi ya nanometero 100, zikwirakwira neza muri polymer kandi zikongera ubwiyongere bw'ubushyuhe. Ushobora kuzikoresha mu bikoresho by'ikoranabuhanga bigezweho cyangwa amavuta meza.

Kumenya Igipimo Gikwiye

Ugomba gupima ingano ikwiye y'ifu ya BN ku mavuta yawe. Gukoresha ifu ya Hexagonal Boron Nitride mu mavuta bikora neza iyo ukoresheje igipimo cyizaUbushakashatsi bwerekana ko 0.5%, 1.0%, na 2.0% ari ibintu bisanzwe. Igipimo cya 1% kiguha imikorere myiza yo gusiga amavuta. Iyo ukoresheje ibirenze 1%, ushobora kubona impinduka mu miterere ya mekanike kuko ifu ya BN idakunda amazi. Tangira na 1% hanyuma uhindure ukurikije uko wakoresheje.

Inama: Buri gihe gerageza amavuta yawe ukoresheje agace gato mbere yo kuyagura. Ibi bigufasha kubona uburyo bwiza bwo kuyakoresha no kuyakoresha neza.

Uburyo bwo Kuvanga Uburyo bwo Gukwirakwiza Ingano Ingana

Urashaka ko ifu ya BN yawe ikwirakwira neza mu mavuta. Guhindura ubuso no gukora, nko gushyiramo imiti cyangwa kuvura plasma, bifasha ifu kuvanga neza. Ubu buryo bunoza imikoranire hagati y'ifu n'amavuta. Ushobora kandi gukoresha irangi rya surfactant.

• Inyongeramusaruro z'imiti zituma ifu iguma ifunze.
• Guteranya cyangwa gutigisa bifasha kuvanga ifu neza.

Ku kuvanga mu nganda, koresha ifu ya BN nziza cyane ku bikoresho bito bya firime n'ibivanze bya polymer. Ifu ya sub-micron (D50 ≤ 0.5 μm) iguha amavuta akomeye kandi ikwirakwira neza mu mavuta n'amavuta. Ibicuruzwa nka Solidex BB025, Solidex B004, na Solidex B050 ni amahitamo meza yo gukora.

Ingero z'Ikoreshwa: Amavuta yo kwisiga mu modoka, mu nganda, no mu bintu byihariye

Ushobora gukoresha ifu ya BN mu bintu byinshi byo gusiga amavuta. Mu mavuta yo mu modoka, yongera ubushobozi bwo gutwara imizigo, igabanya gukururana, kandi ikongera igihe cyo kuyikoresha. Imbonerahamwe iri hepfo igaragaza uburyo ingano zitandukanye zigira ingaruka ku kugabanya gukururana:

Ibizamini byerekana ko kongeramo ifu ya BN 1% mu mavuta y’ubutare bigabanya kwangirika no gutuma ubushyuhe budakwirakwira. Mu mavuta yo mu nganda, ifu ya BN yongera igihe cyo kubaho kw'ibikoresho kandi ikagabanya ikiguzi cyo kubungabunga. Ikora neza mu bidukikije birimo ubushyuhe bwinshi aho andi mavuta yananirana. Amavuta yihariye, nk'akoreshwa mu gucura cyangwa ibikoresho by'ikoranabuhanga, yungukira ku bushyuhe bwa BN no ku buryo ikora neza.

• Ifu ya BN yongera ubushyuhe n'ubushobozi bwo gutwara ibintu.
• Bigabanya kwangirika no kwangirika mu buryo bwa mekanike.
• Ubona igihe kirekire cyo gutanga serivisi kandi amafaranga yo kuyisana akaba make.

Inama zo kubika, gucunga no guhuza

Ugomba kubika ifu ya BN n'amavuta yo kwisiga neza. Bika hagati ya -20°C na 60°C kugira ngo wirinde gushonga no gukomeza gukora neza. Iyo uvanze ifu ya BN n'amavuta y'ibanze atandukanye, ushobora kubona impinduka mu miterere nko kwinjira no gucika kw'amaraso. Gukoresha ifu ya Hexagonal Boron Nitride mu mavuta bishobora kugira ingaruka ku buryo ikora neza, cyane cyane mu mavuta.

Ubudasa bw'ubushyuhe hagati y'ifu ya BN n'ibikoresho bya matrix bishobora gutera imihangayiko imbere mu mubiri. Iyi mihangayiko ishobora gutera imishwanyagurike mito no gucikamo ibice. Buri gihe genzura niba amavuta yawe y'ibanze n'umubyimba bihuye.

Icyitonderwa: Kutamenyana hagati ya polarity ya carrier na matrix bishobora gutera kudahuzagurika. Gerageza formulasiyo yawe mbere yo kuyikora yose.

Ibitekerezo ku mutekano n'ibidukikije

Ugomba gukurikiza amabwiriza y’umutekano mu gihe ukoresha ifu ya BN. Ambara utumashini duhumeka twa N95 twemewe na NIOSH mu mirimo isanzwe hamwe na filter za P100 ahantu hafite ubushyuhe bwinshi. Koresha ubwirinzi bw’amaso bwujuje ibisabwa na ANSI Z87.1 hamwe n’uturindantoki tudakoresha imiti. Komeza guhumeka ku kazi kuri metero 100 ku munota aho umuntu afata kugira ngo wirinde ivumbi ryiyongera. Kurikiza imipaka ya OSHA ya 15 mg/m³ ku mukungugu wose na 5 mg/m³ ku duce duhumeka. Bika amavuta ya BN mu bushyuhe bwagenwe.

Ifu ya BN ishyigikira umusaruro w’icyatsi kibisi. Isimbura ibikoresho byangiza nk’ibirahuri birwanya udukoko na grafiti. Ibi bigabanya umwanda w’ibidukikije kandi bikanoza imikorere mu nganda nko gucura.

Icyibutso cy'umutekano: Tegura uburyo bwihutirwa bwo kuvura isuka. Kubika no gukoresha neza bigumisha ahantu ukorera hatekanye kandi amavuta yawe yo kwisiga akagira akamaro.

Ushobora kunoza amavuta yawe yo kwisiga ukoresheje ifu ya boron nitride ifite impande esheshatu.

1. Shyiramo ifu ukoresheje ibikoresho bifunga by’umwimerere.
2. Ongeraho ibikoresho byo gukanda.
3. Kora utubumbe kugira ngo ururenda rugende neza.
4. Kanda hanyuma ucurange kugira ngo ubone umusaruro mwiza.

• Ubona amavuta meza kandi ukagira imikorere myiza.
• Inganda ubu zikoresha ibi kuri moteri n'imashini zigezweho.
• Ikoranabuhanga rishya rya nano rizatuma ibi bisiga birushaho gukomera.
