Indima ye-adhesives ekukhiqizeni ibhodi lesifunda se-ceramic

Kulesi sihloko, sizohlola indima ye-adhesives ekukhiqizeni amabhodi wesifunda se-ceramic kanye nokubaluleka kwawo ekuzuzeni amabhodi wesifunda aphezulu, athembekile.

Eminyakeni yamuva nje, amabhodi wesifunda se-ceramic athandwa kakhulu ngenxa yezakhiwo zawo ezinhle kakhulu ezishisayo nezikagesi. Asetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi ezezimoto, i-aerospace kanye nezokuxhumana. Inqubo yokukhiqiza yamabhodi wesifunda se-ceramic ihilela izinyathelo ezimbalwa eziyisisekelo, enye yazo ukusetshenziswa kwe-adhesives.

Ngakho-ke, i-adhesive idlala yiphi indima ekukhiqizeni amabhodi esekethe e-ceramic?

Ukuze sikuqonde lokhu, ake siqale sichaze ukuthi iyini i-binder. Ekukhiqizweni kwebhodi lesifunda se-ceramic, i-binder iyisithako esifakwe kungxube ye-ceramic powder ukuze kuthuthukiswe izici zayo zokuphatha nokucubungula. Isebenza njenge-adhesive yesikhashana esiza ukuhlanganisa izinhlayiya ze-ceramic ngesikhathi sokubumba kanye nezinyathelo zokucubungula ezilandelayo.

Indima eyinhloko ye-adhesives ekukhiqizeni ibhodi lesifunda se-ceramic ukunikeza amandla aluhlaza emzimbeni we-ceramic.Amandla aluhlaza asho ikhono le-ceramic engashiswanga ukumelana nokuphathwa, ukubunjwa, nokuthuthwa ngaphandle kokuqhekeka noma ukuqhekeka. Lokhu kubalulekile ngoba izinto ze-ceramic ziyashwabana futhi ziyashwabana, zizenza zibe lula ekulimaleni ngesikhathi sokukhiqiza. Ngokungeza i-binder, ukwakheka kwengxube ye-ceramic powder kuba nokuzinza, okwenza kube lula ukuphatha nokuma ngaphandle kokuguqulwa okuphawulekayo.

Ngaphezu kwamandla aluhlaza, izinamathiselo zidlala indima ebalulekile ekuzuzeni ukunemba kobukhulu obudingekayo kumabhodi esekethe e-ceramic.I-binder ibamba izinhlayiya ze-ceramic ndawonye ngesikhathi sokubumba, ukuvimbela ukuncipha noma ukuwohloka ngokweqile. Lokhu kubaluleke kakhulu lapho kukhiqizwa imiklamo eyinkimbinkimbi yebhodi lesifunda edinga amaphethini anembile futhi ayinkimbinkimbi. Ngaphandle kwe-binder, izinhlayiya ze-ceramic zingase zinyakaze noma zigudluke phakathi nenqubo yokubumba, kubangele ukuhlanekezela kwephethini kanye nokusebenza okusengozini.

Esinye isici esibalulekile sokunamathela ekukhiqizeni ibhodi lesifunda se-ceramic yikhono labo lokulawula i-viscosity ye-ceramic slurries.I-Slurry ingxube yempushana ye-ceramic, izibophezelo nezinye izithasiselo ezilengiswe endaweni ewuketshezi. I-viscosity ye-slurry inquma ukugeleza kwayo kanye nokubekeka kalula ku-substrate. Ngokulungisa okuqukethwe kwe-binder, abakhiqizi bangashintsha i-viscosity ye-slurry ukuqinisekisa ukuthi amabhodi wesifunda ahlanganiswe noma aphrintiwe ngokulinganayo.

Ukwengeza, i-binder isiza ekukhipheni izinto eziphilayo ngesikhathi sokudubula.Amabhodi wesifunda se-Ceramic ahamba ngenqubo yokushisa ephezulu lapho i-adhesive ishisa futhi ihlehle. Ukushiswa kwe-binder kuqeda izingxenye ze-organic, kushiya isakhiwo esihlanzekile se-ceramic. Ukukhipha i-adhesive kubalulekile ngoba kuvimbela ukwakheka kwekhabhoni esele, engathinta kabi izakhiwo zikagesi nezokushisa zebhodi.

Kubalulekile ukuqaphela ukuthi ama-adhesives asetshenziselwa ukukhiqizwa kwamabhodi wesifunda se-ceramic kufanele akhethwe ngokucophelela ukuze kuqinisekiswe ukuhambisana nezakhiwo ezifunwayo zomkhiqizo wokugcina.Ngokufanelekile, i-adhesive kufanele ibe nezindawo ezinhle zokubopha, ukuncipha okuphansi kanye nezinsalela ezinganakwa ngemva kokubola. Ukukhethwa kwe-adhesive efanelekile kuncike ezintweni ezifana nohlobo lwe-ceramic material, izidingo zokusebenza ezidingekayo kanye nenqubo yokukhiqiza esetshenzisiwe.

Ngokufigqiwe,izinto ezinamathelayo zidlala indima ebalulekile ekukhiqizeni amabhodi esekethe e-ceramic. Zinikeza amandla aluhlaza, zilawula ukunemba kwe-dimensional, zilawula i-slurry viscosity kanye nosizo ekukhishweni kwezinto eziphilayo. Ukuqonda kanye nokwenza kahle indima yokunamathela kubalulekile ekutholeni amabhodi esekethe e-ceramic asezingeni eliphakeme anezakhiwo ezinhle kakhulu ezishisayo nezikagesi. Njengoba isidingo samabhodi esifunda se-ceramic siqhubeka sikhula, abakhiqizi kumele baqhubeke nokuhlola nokuthuthukisa ubuchwepheshe bokunamathela obusha ukuze bahlangabezane nezidingo zemboni eziguqukayo.
