Indima ye-adhesives kwimveliso yebhodi yesekethe ye-ceramic

Kule nqaku, siza kuhlolisisa indima ye-adhesives kwimveliso yeebhodi zeesekethe ze-ceramic kunye nokubaluleka kwazo ekufezekiseni umgangatho ophezulu, iibhodi zeesekethe ezithembekileyo.

Kwiminyaka yakutshanje, iibhodi zeesekethe ze-ceramic ziye zaziwa ngokubanzi ngenxa yeempawu zabo ezintle zokushisa kunye nombane. Zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa iimoto, i-aerospace kunye nonxibelelwano. Inkqubo yokuvelisa iibhodi zeesekethe ze-ceramic ibandakanya amanyathelo amaninzi asisiseko, enye yazo kukusetyenziswa kwe-adhesives.

Ngoko ke, yintoni indima encamathelayo kwimveliso yeebhodi zeesekethe ze-ceramic?

Ukuyiqonda le nto, masiqale sichaze ukuba yintoni isibophelelo. Kwimveliso yebhodi yesekethe ye-ceramic, i-binder yinto eyongeziweyo kumxube we-ceramic powder ukuphucula iimpawu zayo zokuphatha kunye nokusebenza. Isebenza njenge-adhesive yesikhashana enceda ukubopha amaqhekeza e-ceramic kunye ngexesha lokubumba kunye namanyathelo okucubungula alandelayo.

Indima ephambili ye-adhesives kwimveliso yebhodi yesekethe ye-ceramic kukubonelela ngamandla aluhlaza kumzimba we-ceramic.Amandla aluhlaza abhekiselele kwisakhono semathiriyeli ye-ceramic engacinywanga ukumelana nokuphathwa, ukubunjwa, kunye nokuthuthwa ngaphandle kokuqhekeka okanye ukuqhekeka. Oku kubalulekile kuba imathiriyeli ye-ceramic i-brittle kwaye i-brittle, ibenza ukuba babe sesichengeni somonakalo ngexesha lemveliso. Ngokudibanisa i-binder, isakhiwo somxube we-ceramic powder sihlala sizinzile, okwenza kube lula ukuphatha kunye nokubumba ngaphandle kokuguqulwa okubalulekileyo.

Ukongeza kumandla aluhlaza, i-adhesives idlala indima ebalulekileyo ekufezekiseni ukuchaneka kwe-dimensional efunekayo kwiibhodi zeesekethe ze-ceramic.I-binder ibamba amaqhekeza e-ceramic kunye ngexesha lenkqubo yokubumba, ukukhusela ukuncipha okukhulu okanye ukuguqulwa. Oku kubaluleke ngakumbi xa kusenziwa uyilo lwebhodi yesekethe enzima efuna iipateni ezichanekileyo nezintsonkothileyo. Ngaphandle kwe-binder, iincinci ze-ceramic zingahamba okanye zitshintshe ngexesha lokubumba, okubangela ukuphazamiseka kwepateni kunye nokusebenza kakubi.

Enye inkalo ebalulekileyo yokunamathela kwimveliso yebhodi yesekethe ye-ceramic kukukwazi kwabo ukulawula i-viscosity ye-ceramic slurries.I-Slurry ngumxube we-ceramic powder, izibophelelo kunye nezinye izongezo ezixhonywe kwindawo yolwelo. I-viscosity ye-slurry inquma ukuhamba kwayo kunye nokulula kokufakwa kwi-substrate. Ngokulungelelanisa umxholo we-binder, abavelisi banokutshintsha i-viscosity ye-slurry ukuqinisekisa ukuba iibhodi zeesekethe ziboshwe okanye ziprintwe ngokulinganayo.

Ukongeza, i-binder inceda ekususeni izinto eziphilayo ngexesha lokudubula.Iibhodi zeesekethe zeCeramic zihamba ngenkqubo yokushisa ukushisa okuphezulu apho i-adhesive iyatshisa kwaye iphule. Ukutshiswa kwe-binder kuphelisa izinto eziphilayo, ukushiya isakhiwo esicocekileyo se-ceramic. Ukususa i-adhesive kubalulekile kuba kuthintela ukubunjwa kwekhabhoni eseleyo, enokuchaphazela kakubi umbane kunye neempawu ze-thermal zebhodi.

Kubalulekile ukuba uqaphele ukuba i-adhesives esetyenziselwa ukuveliswa kweebhodi zeesekethe ze-ceramic kufuneka zikhethwe ngokucophelela ukuqinisekisa ukuhambelana neempawu ezifunwayo zemveliso yokugqibela.Ngokufanelekileyo, i-adhesive kufuneka ibe neendawo ezintle zokudibanisa, i-shrinkage ephantsi kunye ne-residu engafanelekanga emva kokubola. Ukukhethwa kwe-adhesive efanelekileyo kuxhomekeke kwizinto ezifana nohlobo lwezinto ze-ceramic, iimfuno ezifunekayo zokusebenza kunye nenkqubo yokuvelisa esetyenziswayo.

Isishwankathelo,i-adhesives idlala indima ebalulekileyo kwimveliso yeebhodi zeesekethe ze-ceramic. Banikezela ngamandla aluhlaza, balawule ukuchaneka kwe-dimensional, lawula i-slurry viscosity kunye nokunceda ekususweni kwezinto eziphilayo. Ukuqonda kunye nokuphucula indima ye-adhesives ibalulekile ekufumaneni iibhodi zesekethe ze-ceramic ezikumgangatho ophezulu ezineempawu ezibalaseleyo zokushisa kunye nombane. Njengoko imfuno yeebhodi zesekethe yeceramic iqhubeka nokukhula, abavelisi kufuneka baqhubeke bephonononga kwaye baphuhlise itekhnoloji entsha yokuncamathela ukuhlangabezana neemfuno zeshishini.
