Txheej txheem cej luam ntawm kev kho mob qib steel hlau
Piv nrog rau cov qauv kev lag luam hauv stainless hlau, Kev kho mob stainless hlau yuav tsum muaj kev tiv thaiv zoo heev hauv tib neeg lub cev, kom txo cov hlau ions, kev sib cais, tsis txhob cuam tshuam kev cuam tshuam, kev ntxhov siab corrosion thiab lub zos corrosion tshwm sim, tiv thaiv kev puas tsuaj los ntawm cov khoom siv cog, xyuas kom cov kev nyab xeeb ntawm cov khoom siv cog. Yog li ntawd, nws cov tshuaj muaj pes tsawg leeg yuav tsum nruj dua li kev lag luam stainless hlau. Kev kho mob stainless hlau tshwj xeeb tshaj yog cog rau hauv tib neeg lub cev, Ni thiab Cr alloy cov ntsiab lus tau siab dua li cov hlau tsis zoo tib yam (feem ntau ua tau raws li qhov kev txwv siab ntawm cov hlau tsis zoo tib yam). Cov ntsiab lus ntawm impurity ntsiab xws li S thiab P yog qis dua li ntawm cov hlau tsis zoo tib yam, thiab nws tau qhia meej tias qhov loj ntawm cov hlau tsis muaj hlau yuav tsum tsawg dua qib 115 (zoo system) thiab qib 1 (txheej txheem coarse. ) raws li, thaum tus qauv ntawm cov khoom lag luam zoo tib yam stainless hlau tsis muab tso rau tshwj xeeb cov kev cai rau kev suav nrog.
Kev kho mob stainless hlau tau dav siv los ua cov khoom siv kho mob cog thiab cov khoom siv kho mob vim nws cov biocompatibility zoo, zoo txhua yam khoom, thiab zoo heev corrosion kuj ntawm lub cev kua thiab zoo processability. Kev kho mob stainless hlau yog dav siv los ua ntau yam kev sib koom ua ke thiab pob txha hauv cov cuab yeej kho mob, xws li txhua yam khoom siv dag zog, lub hauv caug, lub xub pwg, lub luj tshib; Hauv kev kho hniav, nws yog dav siv hauv kev kho hniav, kho hniav orthotics, kho hniav hauv paus implantation; Hauv kev phais plawv, nws yog siv rau hauv plawv stent. Ntxiv nrog rau kev ua ntau yam kev phais phais, kev kho mob stainless hlau kuj tseem siv los ua ntau yam kev kho mob phais lossis cov cuab yeej, xws li phais phais.
Cov qib steel sib txawv coj qhov sib txawv ntawm cov koob sutures, tab sis tag nrho cov no tuaj yeem ua tau raws li qhov xav tau qis tshaj ntawm kev phais kev nyab xeeb.
Hauv qab no daim ntawv teev cov kev kho mob stainless hlau uas feem ntau yuav tsum tau siv nyob rau hauv phais sutures koob.
