Izinto ezinamathelayo zingene kuzo zonke izici zokuphila kwethu kwansuku zonke ngenxa yokusebenza kwazo okuhle kakhulu. Ngokuthuthuka kwesayensi nobuchwepheshe, izinto zokunamathisela ziye zavela ezimbonini eziningi. Ama-Adhesives kancane kancane abe yingxenye ebalulekile yokukhiqiza ezimbonini ezihlukahlukene.
Lesi sihloko sizokwethula isiqondiso esisha sohlelo lokusebenza kanye nezinzuzo zokunamathela:
01 Izinhlelo zokusebenza ezintsha zokunamathisela
- 1. Anti-ukugqwala kwemishini
Njengamanje, amapayipi esitimu emikhumbi ngokuvamile afakwe i-aluminium silicate ne-asbestos. Nokho, ngenxa yokuvuza noma ukushintshashintsha kokushisa nokubanda, amanzi ajiyile akhiqizwa futhi aqoqwe odongeni olungaphandle lwepayipi lesitimu engxenyeni engezansi. Ngaphezu kwalokho, ipayipi le-steam lingaphansi kokushisa okuphezulu nosawoti oncibilikayo isikhathi eside, futhi udonga lwangaphandle lugqwalile kakhulu. Ngenxa yalesi sizathu, ingcina yochungechunge lwengilazi yamanzi ingasetshenziswa njengento yokumboza ongqimbeni olungezansi lwe-aluminium silicate ukuze kwakhiwe uqweqwe olunoqweqwe - I-coefficient yayo yokwandisa okushisayo ifana nepayipi, ngokucindezeleka okuncane kokushisa futhi akukho ukuqhekeka. Ekufakweni kwemishini, izingxenye zivame ukulungiswa ngama-bolts.
Izingxenye ezilungiswe ngamabhawudi zizovezwa emoyeni isikhathi eside, okuzodala ukugqwala kwemifantu. Ngesikhathi sokusebenza komshini, amabhawodi angase axege ngezinye izikhathi ngenxa yokudlidliza okukhulu. Ukuze uxazulule le nkinga, izingxenye zokuxhuma zingahlanganiswa ne-adhesives ye-inorganic ngaphambi kokuxhuma nama-bolts ngesikhathi sokufakwa kwemishini. Lokhu akukwazi nje ukudlala indima ekuqiniseni, kodwa futhi kube nomthelela wokulwa -
- 2. Isetshenziselwa izinjongo ze-biomedical
Ukwakheka kwezinto ezibonakalayo ze-hydroxyapatite Ca10(PO4)6(OH)2 (HA okwesikhashana) i-bioceramic iseduze nezingxenye ezingaphili zethambo lomuntu, ine-biocompatibility enhle, ingakha isibopho esiqinile samakhemikhali nethambo, futhi iyinto efanelekile yokushintsha izicubu eziqinile. Kodwa-ke, izimila ze-HA ezilungiselelwe njengamanje ngokuvamile zine-modulus enwebekayo ephezulu namandla aphansi, futhi umsebenzi awulungile. I-Phosphate glass adhesive isetshenziselwa ukuhlanganisa i-HA raw material powder ndawonye ezingeni lokushisa eliphansi kunezinga lokushisa elivamile le-sintering, ngaleyo ndlela kunciphisa i-elastic modulus nokuqinisekisa umsebenzi wezinto ezibonakalayo.
Ukusetshenziswa kwezinamatheliso kwezokwelapha kunconywa njengendawo entsha yokukhula embonini yokunamathisela. Izinamathiselo zesakhiwo ezakhiwe nge-epoxy resin noma i-polyester engafakwanga.
