I-Adhesive evuthayo iyindlela ekhethekile enamathela, ikakhulukazi eyakhiwa kabusha i-resin kanye ne-filler (njengesiliva, i-nickel, i-tickel, i-graphite, i-graphite, i-njll.

Kunezinhlobo eziningi zokunamathela okuphakelayo. Ngokwezinhlayiya ezihlukene zokudla, izinamathiselo eziqhutshwayo zingahlukaniswa ngensimbi (igolide, isiliva, ithusi, i-aluminium, i-zinc, i-iron, i-adhesives esekelwe kwikhabhoni. Phakathi kokunamathela okungenhla okuphambeneyo, ukuvumelanisa okuhlanganisiwe okwenziwe yi-purn powder kunesimo esihle kakhulu, ukunamathela kanye nokuqina kwamakhemikhali, ngeke kube yi-oxidised ku-adhesive ungqimba, futhi ngeke kube yi-oxidised ku-adhesive ungqimba, futhi ngeke kuthathwe kakhulu noma ku-oxidised, i-oxidi ekhiqizwayo, i-oxidi ekhiqizwayo isenokuqhutshwa okuhle. Ngakho-ke, emakethe, ikakhulukazi kumadivayisi kagesi anezidingo eziphezulu zokwethenjwa, izinamathiseli ezinamathela nge-powder yesiliva njengoba ama-filler asebenzayo asetshenziswa kakhulu. Ekukhetheni kwe-matrix resin, i-epoxy resin isiphenduke isinqumo sokuqala ngenxa yokuqukethwe kwayo okuphezulu kwamaqembu asebenzayo, amandla aphezulu ahlangana, anamanzi amahle kakhulu, kanye nezakhiwo ezinhle kakhulu zemishini.

Niniisiliva powderIngezwa ekunamathisweni e-epoxy njenge-filler esebenzayo, indlela yayo yokuhambisa ukuxhumana phakathi kwamaphayiphu wesiliva. Ngaphambi kokunamathela okuvuthayo kuphelelwe futhi kumiswe, i-powder yesiliva endaweni enamathela e-epoxy ikhona ngokuzimela futhi ayikhombisi ukuxhumana okuqhubekayo, kepha isesimweni esingesihlekisayo nesiphambayo. Ngemuva kokuphulukisa nokumiswa, ngenxa yokwelashwa kohlelo, amapopi esiliva axhumene komunye nomunye esimweni se-chain ukwakha inethiwekhi esebenzayo, ekhombisa ukuvumelanisa. Ngemuva kokungeza i-powder yesiliva ekuhlolweni kwe-epoxy ngokusebenza okuhle (inani le-ejenti elinamandla kanye ne-ejenti yokulapha ngamaphesenti ayi-10 no-7% we-epoxy resin mass, ngokulandelana), ukusebenza kuhlolwe ngemuva kokwelapha. Ngokwemininingwane yokuhlola, njengoba inani lesiliva elisezingeni lokuthambisa anamathela, ukumelana kwevolumu kwehliswa kakhulu. Lokhu kungenxa yokuthi lapho okuqukethwe kwe-striver powder kuncane kakhulu, inani le-resin ohlelweni lingaphezu kwalokho kwe-filler yesiliva yesiliva, futhi i-powder yesiliva kunzima ukuxhumana nenethiwekhi esebenzayo, ngaleyo ndlela ikhombisa ukumelana okuphezulu. Ngokukhuphuka kwesamba sokugcwaliswa kwempuphu yesiliva, ukwehla kwe-resin kwandisa ukuxhumana kwe-powder yesiliva, okuzuzisa ukwakheka kwenethiwekhi yenethiwekhi futhi kunciphise ukumelana kwevolumu. Lapho inani lokugcwalisa lingama-80%, ukumelana kwevolumu kungu-0.9 × 10-4phω • cm, okunokuqhutshwa okuhle, FYI.

Amaphakethe wesilivaNgosayizi oguqukayo wezinhlayiyana (kusuka ku-20nm-10um), amajamo ahlukene (ama-spherical, asondele-we-spherical, insiza eyenziwe ngokwezifiso ye-density, SSA, njll. Ayatholakala.

Ngeminye imininingwane, sicela ungangabazi ukuxhumana nathi.
