Cov Khoom Txiav Txim Txoj Cai: Cov khoom sib xyaw ntawm cov khoom ntawm cov koob pov tseg tseem ceeb cuam tshuam rau txoj kev uas lawv muab pov tseg.

Cov khoom txiav txim siab txog txoj hmoo: Cov khoom siv ntawm cov khoom pov tseg cov koob muaj feem cuam tshuam rau txoj kev uas lawv muab pov tseg. Nkag siab txog qhov kev sib raug zoo no yog thawj kauj ruam mus rau kev pov tseg kom nyab xeeb. Stainless hlau koob, raws li hom feem ntau, ntsib cov teeb meem tshwj xeeb hauv lawv qhov kev pov tseg. Cov hlau no -chromium-nickel alloy, txawm tias corrosion- tiv taus, ib txwm degrades nyob rau hauv ib puag ncig ntau pua xyoo. Qhov tseem ceeb tshaj, qhov chaw ntawm cov koob siv stainless hlau yuav kis tau tus kab mob siab B (uas muaj sia nyob tau 7 hnub ntawm chav tsev sov), tus kab mob siab C (uas muaj sia nyob ntev li 16 teev txog 4 hnub), lossis kab mob HIV (uas muaj sia nyob ntev li ob peb teev mus rau ob peb hnub). Cov txheej txheem pov tseg kom raug yog: tam sim ntawd tso cov koob siv rau hauv lub thawv ntim tshwj xeeb, tsis txhob sib cais rab koob los ntawm cov koob txhaj tshuaj, vim qhov kev ua no ua rau 40% ntawm cov koob txhaj tshuaj ntawm cov neeg ua haujlwm kho mob. Lub thawv sharps yuav tsum tau ua los ntawm puncture{13}}cov ntaub ntawv resistant, thiab yuav tsum tau muab kaw thaum lub filling ncav cuag 3/4, thiab xa mus rau lub chaw kho mob pov tseg pov tseg rau siab - kub incineration, nrog ib tug kub ntawm ntau tshaj 850℃thiab lub sij hawm ntawm 2 vib nas this kom paub meej inactivation ntawm pathogens. Nickel-chromium alloy koob xws li Inconel thiab Monel muaj cov feem ntau ntawm npib tsib xee, chromium, molybdenum, thiab lwm yam, thiab cov ntsiab lus no tuaj yeem hloov mus rau hauv cov hlau oxides lom thaum hlawv. Cov kws tshaj lij ua cov nroj tsuag tau txais cov txheej txheem "thawj crushing ces melting" txheej txheem: thawj zaug tsoo cov koob mus rau 5 millimeters lossis tsawg dua, thiab tom qab ntawd ua kom sov rau ntau tshaj 1600℃hauv hluav taws xob arc rauv kom yaj tag thiab cais cov hlau. Cov hlau molten tuaj yeem rov ua dua tshiab rau kev tsim cov khoom lag luam stainless hlau, tab sis qhov purity ntawm npib tsib xee rov qab yuav tsum tau tswj nruj me ntsis kom tsis txhob siv cov khoom noj khoom haus. Nws tsim nyog sau cia tias qee tus neeg tsis haum rau npib tsib xee, thiab raug nickel- cov khoom pov tseg tuaj yeem ua rau mob dermatitis, yog li cov neeg ua haujlwm yuav tsum hnav hnab looj tes ob npaug. Kev nce ntawm cov koob yas yog los ntawm lub tswv yim ntawm ib leeg - siv kev kho mob, tab sis lawv qhov kev pov tseg tau ua rau muaj teeb meem ib puag ncig tshiab. Kev kho mob polypropylene thiab polycarbonate yas yuav tsim cov tshuaj dioxins thaum lub sij hawm incineration, uas yog cov kab mob tsis tu ncua uas nyob hauv cov khoom noj khoom haus thiab muaj tshuaj lom heev. Cov txheej txheem kev ua haujlwm niaj hnub no siv kev sib xyaw ua ke ntawm "steam sterilization + mechanical crushing": thawj zaug tau txais 134℃siab-siab chav kho rau 45 feeb los xyuas kom meej kev nyab xeeb; tom qab ntawd tsoo lawv mus rau hauv cov khoom me me, uas yog siv los ua cov khoom siv qis-qib yas raw khoom rau kev tsim cov lauj kaub paj, txoj kev thaiv, thiab lwm yam, rau cov khoom tsis yog - tiv tauj. Txawm li cas los xij, qhov kev sib tw loj tshaj plaws ntawm cov koob yas yog "tsis pom kev tsis meej pem" - lawv tuaj yeem ua yuam kev rau cov yas zoo tib yam thiab sib xyaw rau hauv cov khoom siv rov ua dua tshiab, yog li lawv yuav tsum tau ntim rau hauv cov xim daj thiab cov cim kom meej meej. Cov koob iav tsis tshua muaj, tab sis lawv tseem siv hauv qee qhov chaw kuaj mob thiab cov xwm txheej tshwj xeeb. Borosilicate iav muaj tshuaj lom neeg ruaj khov heev tab sis yog nkig, thiab tom qab tawg, nws tsim cov khoom tawg. Thaum tuav, lawv yuav tsum tau muab khaws cia rau hauv tuab- cov thawv ntim cov phab ntsa cais kom tsis txhob sib xyaw nrog cov khoom siv hlau lossis yas ntse. Cov kws tshaj lij ua cov nroj tsuag yuav tsoo iav koob ua ke nrog lwm cov iav kho mob pov tseg, ntxuav thiab tshuaj tua kab mob, thiab tom qab ntawd yaj lawv, siv lawv ua cov ntaub ntawv rwb thaiv tsev lossis iav fiber ntau raw khoom. Silica-coated koob xav tau kev saib xyuas ntxiv hauv kev tuav. Silica roj tuaj yeem decompose ntawm qhov kub thiab txias los tsim siloxane, uas nyob hauv ib puag ncig thiab muaj tshuaj lom heev. Yog li ntawd, qhov kub hnyiab yuav tsum tau tswj kom meej ntawm 900-1000℃kom ua tiav oxidation. Qhov kev nce qib tshiab tshaj plaws hauv cov ntaub ntawv tshawb fawb taw qhia rau "tsim degradation" koob: polylactic acid koob degrade nyob rau hauv compost tej yam kev mob nyob rau hauv 6 lub hlis; magnesium alloy koob maj mam corrode nyob rau hauv lub cev kua thiab nws thiaj li excrete harmlessly. Cov kev tsim kho tshiab no tsis yog tsuas yog txo cov khib nyiab xwb tab sis kuj tseem hloov pauv cov logic tuav - los ntawm "yuav ua li cas" mus rau "yuav ua li cas kom tsis txhob tuav".
