Umehluko phakathi kwezibonakhulu ze-metallographic eziqondile nezihlanekezelwe

1. Namuhla ake sibone umehluko phakathi kwemakroskopu e-metallographic eqondile kanye nehlanekezelwe:Isizathu esenza isibonakhulu se-metallographic ehlanekezelwe sibizwe ngokuthi i-inverted ukuthi i-lens yenhloso ingaphansi kwesiteji, futhi ucezu lokusebenza ludinga ukuphendulwa sibheke phansi esiteji ukuze sibukwe futhi sihlaziywe. Ifakwe kuphela uhlelo lokukhanyisa olubonakalayo, olufaneleka kakhulu ukubuka izinto zensimbi.

Isibonakhulu se-metallographic esiqondile sine-lens yenhloso esiteji futhi isiqeshana somsebenzi sibekwe esiteji, ngakho-ke sibizwa ngokuthi i-upright.Ingakwazi ukuhlonywa uhlelo lokukhanyisa oludluliswayo kanye nesistimu yokukhanyisa ebonisiwe, okungukuthi, imithombo emibili yokukhanya ngaphezulu nangaphansi, ekwazi ukubona amapulasitiki, irabha, amabhodi wesifunda, amafilimu, ama-semiconductors, izinsimbi nezinye izinto.

Ngakho-ke, esigabeni sokuqala sokuhlaziywa kwe-metallographic, inqubo yokulungiselela isampula ehlanekezelwe idinga kuphela ukwenza indawo eyodwa, elula kunaleyo eqondile. Iningi lokwelapha ukushisa, ukusakaza, imikhiqizo yensimbi kanye nezimboni zemishini zikhetha imakroskopu ye-metallographic ehlanekezelwe, kuyilapho amayunithi ocwaningo lwesayensi ekhetha amamakroskopu e-metallographic aqondile.

2. Izinyathelo zokuqapha ngokusebenzisa isibonakhulu se-metallographic:

1) Kufanele sinake lokhu okulandelayo lapho sisebenzisa lesi sibonakhulu se-metallographic level:

2) Gwema ukubeka isibonakhulu ezindaweni ezinokukhanya kwelanga eliqondile, izinga lokushisa eliphezulu noma umswakama ophezulu, uthuli, nokudlidliza okuqinile, futhi uqinisekise ukuthi indawo yokusebenza iyisicaba futhi isezingeni.

3)Kuthatha abantu ababili ukuhambisa isibonakhulu, umuntu oyedwa ubambe ingalo ngezandla zombili, omunye abambe phansi kwesibonakhulu lesibonakhulu futhi asibeke ngokucophelela.

4) Lapho uhambisa isibonakhulu, ungasibambeli isibonakhulu isibonakhulu, ugxile knob, observation tube, kanye nomthombo wokukhanya ukuze ugweme umonakalo isibonakhulu.

5)Ingaphezulu lomthombo wokukhanya lizoshisa kakhulu, futhi kufanele uqinisekise ukuthi kunesikhala esanele sokulahla ukushisa eduze komthombo wokukhanya.

6)Ukuqinisekisa ukuphepha, qiniseka ukuthi inkinobho enkulu iku-"O" ngaphambi kokufaka isibani noma i-fuse.
