Njengoba sonke sazi, kunezinhlobo eziningi zezinto ezithwala impahla emakethe, futhi izinto zethu ezivamile zokuthwala zihlanganisa izigaba ezintathu zezinto zensimbi, izinto zensimbi ezinama-porous kanye nezinto ezingezona ezensimbi.

Izinto zensimbi

I-Bearing alloy, ithusi, i-aluminium base alloy, i-zinc base alloy nokunye konke kuyizinto zensimbi.Phakathi kwazo, i-alloy bearing, eyaziwa nangokuthi i-alloy emhlophe, ngokuyinhloko i-alloy yokuhola, ithini, i-antimony noma ezinye izinsimbi.Ingaba namandla aphansi ngaphansi kwezimo zomthwalo osindayo kanye nesivinini esikhulu.Isizathu siwukuthi inokumelana okuhle kokugqoka, i-plasticity ephezulu, ukusebenza kahle ekusebenzeni, ukuqhutshwa kahle kwe-thermal, ukumelana okuhle kweglue kanye ne-adsorption enhle ngamafutha.Kodwa-ke, ngenxa yentengo yayo ephezulu, kufanele ithululwe esihlahleni esithwala ithusi, umucu wensimbi noma insimbi ecijile ukuze kwakhiwe uqweqwe oluncane.

(1) I-alloy ehambisanayo (evame ukubizwa ngokuthi i-Babbitt alloy noma i-alloy emhlophe)
I-Bearing alloy iyingxube ye-tin, lead, antimony nethusi.Kuthatha ithini noma umthofu njenge-matrix futhi iqukethe izinhlamvu eziqinile ze-antimony tin (sb SN) ne-copper tin (Cu SN).Okusanhlamvu okuqinile kudlala indima ephikisana nokugqoka, kuyilapho i-matrix ethambile ikhulisa ipulasitiki yezinto.I-elastic modulus kanye nomkhawulo wokunwebeka we-bearing alloy iphansi kakhulu.Phakathi kwazo zonke izinto ezithwalayo, Ukushumeka kwayo nokuhambisana nokungqubuzana kungcono kakhulu.Kulula ukungena nejenali futhi akulula ukuluma ngejenali.Kodwa-ke, amandla e-alloy okuzala aphansi kakhulu, futhi isihlahla esithwalayo asikwazi ukwenziwa sodwa.Ingaxhunywa kuphela esihlahleni esithwala ithusi, sensimbi noma esisansimbi njengomugqa wokuthwala.I-Bearing alloy ifanele umthwalo osindayo, izikhathi zejubane eliphakathi nendawo, futhi intengo iyabiza.

(2) Ingxube yethusi
I-alloy yethusi inamandla amakhulu, i-antifriction enhle kanye nokumelana nokugqoka.Ithusi linezakhiwo ezingcono kunethusi futhi liyinto esetshenziswa kakhulu.I-bronze ihlanganisa i-tin bronze, i-lead bronze ne-aluminium bronze.Phakathi kwazo, i-tin bronze ine-antifrict engcono kakhulu
