Fibre imwe ya safiro Al₂O₃ ahantu ho gushonga hafite ubushobozi bwo gushonga bwa 2072℃ ishobora gukoreshwa mu bikoresho by'amadirishya ya laser Ishusho yagaragaye

Ibisobanuro bigufi:

Fibre ya safiro ikozwe muri alumina imwe ya kristu (Al₂O₃), ikaba ari ibikoresho bifite imbaraga nyinshi za mashini, ubushobozi bwo kurwanya ubushyuhe n'ubushobozi bwiza bwo gutwara ubushyuhe. Safira iri mu miterere ya kristu ifite uburebure bwa hexagonal, ubushobozi bwo kohereza urumuri ni 0.146.0μm, kandi ifite ubushobozi bwo kohereza urumuri bwinshi muri bande ya 3.05.0μm. Aho ishonga ya safiro ishongera ni uburebure bwa 2072 ° C, kandi ubukana bwayo ni ubwa kabiri nyuma ya diyama, bityo fibre ya safiro ifite ubushobozi bwo kwihanganira ubushyuhe bwinshi n'imbaraga za mashini.

Uburyo bwo gutegura

1. Fibre ya safiro ikunze gutegurwa hakoreshejwe uburyo bwa laser heated base method (LHPG). Muri ubu buryo, fibre ya safiro ifite umurongo wa geometrike na C-axis ishobora guhingwa, ikaba ifite uburyo bwiza bwo kohereza ibintu hafi ya infrared band. Igihombo gituruka ahanini ku gukwirakwira guterwa n'ubusembwa bwa kristu buri ku buso bwa fibre.

2. Gutegura fibre ya safiro ikozwe muri silica: Ubwa mbere, irangi rya poly (dimethylsiloxane) rishyirwa ku buso bwa fibre ya safiro hanyuma rikavurwa, hanyuma urwego rwasubiwemo rugahindurwa silica kuri 200 ~ 250℃ kugira ngo haboneke fibre ya safiro ikozwe muri silica. Ubu buryo bufite ubushyuhe buke, imikorere yoroshye kandi bufite imikorere myiza cyane.

3. Gutegura fibre ya safiro: Igikoresho cyo gukuraho ubushyuhe bwa laser gikoreshwa mu gutegura fibre ya safiro binyuze mu kugenzura umuvuduko wo guterura fibre ya safiro hamwe n'umuvuduko wo gutwika fibre ya safiro. Ubu buryo bushobora gutegura fibre ya safiro ifite ubugari butandukanye n'intambwe nziza, ishobora kuzuza ibisabwa byihariye.

Ubwoko bwa fibre n'ibipimo byayo

1. Ingano y'umurambararo: Umurambararo wa fibre ya safiro ushobora gutoranywa hagati ya 75 ~ 500μm kugira ngo uhuzwe n'ibisabwa bitandukanye byo gukoreshwa.

2. Fibre y'ubwoko bwa Conical: Fibre ya safiro y'ubwoko bwa Conical ishobora gutuma habaho ingufu nyinshi z'urumuri mu gihe igenzura ko fibre ihinduka. Iyi fibre yongera ubushobozi bwo kohereza ingufu mu buryo bunoze ariko ntigabanya ubushobozi bwo koroshya.

3. Ibikoresho n'ibihuza: Ku migozi y'urumuri ifite umurambararo urenze 100μm, ushobora guhitamo gukoresha ibikoresho bya polytetrafluoroethylene (PTFE) cyangwa ibikoresho bya fiber y'urumuri kugira ngo birinde cyangwa bihuzwe.

Ahantu ho gusaba

1. Imashini ipima ubushyuhe bwinshi: Imashini ya safira kubera ubushyuhe bwayo bwinshi, irwanya ingese, ikwiriye cyane mu kumenya fibre mu bushyuhe bwinshi. Urugero, mu byuma, inganda zikora imiti, mu kuvura ubushyuhe n'ahandi, imashini zipima ubushyuhe bwinshi zishobora gupima neza ubushyuhe bugera kuri 2000 ° C.

2. Kohereza ingufu hakoreshejwe lazeri: Imiterere y'ingufu za safiro ituma zikoreshwa cyane mu bijyanye no kohereza ingufu hakoreshejwe lazeri. Ishobora gukoreshwa nk'ibikoresho byo mu idirishya kugira ngo lazeri zishobore kwihanganira imirasire ya lazeri ikomeye n'ubushyuhe bwinshi.

3. Gupima ubushyuhe mu nganda: Mu rwego rwo gupima ubushyuhe mu nganda, ibikoresho by'ubushyuhe bwinshi bya safiro bishobora gutanga amakuru nyayo kandi ahamye yo gupima ubushyuhe, bifasha gukurikirana no kugenzura impinduka z'ubushyuhe mu gikorwa cyo gukora.

4. Ubushakashatsi bwa siyansi n'ubuvuzi: Mu rwego rw'ubushakashatsi bwa siyansi n'ubuvuzi, fibre ya safiro ikoreshwa kandi mu buryo butandukanye bwo gupima no kumva neza bitewe n'imiterere yayo yihariye y'umubiri n'imiti.

Dukurikije ibyo abakiriya bakeneye byihariye, XKH itanga serivisi zo gushushanya fibre ya safiro ku giti cyabo. Byaba uburebure n'umurambararo wa fibre, cyangwa ibisabwa byihariye by'imikorere y'amatara, XKH ishobora guha abakiriya igisubizo cyiza cyo guhaza ibyo bakeneye binyuze mu gushushanya no kubara by'umwuga. XKH ifite ikoranabuhanga rigezweho ryo gukora fibre ya safiro, harimo na laser heated base method (LHPG), kugira ngo ikore fibre ya safiro nziza kandi ifite imikorere myiza. XKH igenzura neza buri sano mu gikorwa cyo gukora kugira ngo irebe ko ubwiza n'imikorere by'ibicuruzwa bihuye n'ibyo abakiriya biteze.
