Dab tsi ua rau silicon wafer ua rau tib neeg lub cev?

Qhov teeb meem loj tshaj plaws los ntawm silicon rau tib neeg lub cev yog silicosis. Ua los ntawm kev nqus tau ntev ntev ntawm cov hmoov av silica (SiO2) ntau. Silica plua plav nkag mus rau hauv txoj kev ua pa thiab yog engulfed los ntawm lub ntsws macrophages, tso active yam uas txhawb fibroblasts los ua ke ntau collagen. Silica plua plav kuj tseem tuaj yeem ua rau cov macrophages tso tawm lysosomal enzymes, rhuav tshem cov proteins coated ntawm SiO2 nto thiab nthuav tawm cov cell membrane puas. Nws tuaj yeem pib lipid peroxidation, tsim cov dawb radicals, kev puas tsuaj lossis txawm tua cov macrophages, thiab cov hlwb tuag. Nws tuaj yeem tsim cov fibroblasts uas nyob ib sab los tsim cov collagen. Silica plua plav tawm dua thiab yog phagocytosed los ntawm lwm cov macrophages los tsim collagen fibers ntau. Raws li lub sijhawm dhau mus, tus kab mob nce zuj zus thiab ua rau silicosis. Cov neeg ua haujlwm mines, cov neeg ua haujlwm hauv qhov av hauv ntau cov mines hlau, cov neeg ua haujlwm masonry hauv kev lag luam cov ntaub ntawv refractory, iav khoom thiab quartz grinders, thiab cov xuab zeb ntxuav yog txhua yam yuav raug silica plua plav thiab tsim silicosis. Vim muaj kev loj hlob ntawm kev ua haujlwm tiv thaiv plua plav, qhov tshwm sim ntawm silicosis tau txo qis, tab sis nws tseem tsis tau tswj tau tag nrho, thiab nws tseem yog ib qho ntawm cov kab mob tseem ceeb tshaj plaws hauv kuv lub tebchaws.
Silicon wafers Ameslikas tsis muaj kev phom sij, tab sis kev noj zinc ntau dhau yuav ua rau tib neeg lub cev thiab tuaj yeem ua rau kiv taub hau, ntuav thiab raws plab. Cov khoom tseem ceeb yog silica, tseem hu ua xuab zeb, yog li nws feem ntau tsis muaj mob rau tib neeg lub cev.
