Koj puas paub cov khoom siv ntawm stainless hlaurau Pharmaceutical Machinery hauv Pharma Process?
Tsis ntev los no, cov kws kho mob neeg hlau tau nug seb cov khoom siv tshuaj stainless hlau siv hauv chav huv huv tuaj yeem siv 304 stainless hlau? Puas yog nws tsim nyog siv 316L rau cov khoom uas nkag mus rau hauv cov tshuaj?
Hauv cov lus teb rau lo lus nug no, cov kws tshaj lij kev lag luam tau muab ntau cov lus teb, uas tuaj yeem ua tiav raws li ib qho ntsiab lus: 316L cov khoom siv feem ntau yog siv, tab sis tsis muaj qhov yuav tsum tau ua, yog li 316L tsis tas yuav tsum tau ua, thiab kev xaiv tsuas yog nyob ntawm cov khoom. yam ntxwv.
& quot; Lub hom phiaj txiav txim siab cov khoom siv. Yog tias nws yog kev npaj ua kua yooj yim, cov khoom siv tuaj yeem zam tau. Tab sis yog tias nws yog cov tshuaj tiv thaiv ncaj qha, 304 yuav tsis ua haujlwm. Qhov thib ob, koj yuav tsum pom cov khoom lag luam zoo, thiab qhov yuav tsum tau ua rau ntau yam hlau." Nov yog qhov kev lag luam hais.
Yog li, qhov txawv ntawm 316L thiab 304 yog dab tsi? Raws li cov ntaub ntawv, los ntawm kev siv cov ntsiab lus ntawm kev pom, 304 yog cov khoom siv hauv cov hlau tsis muaj steel nrog qhov ntom ntawm 7.93 g / cm³, thiab 316L yog cov khoom siv hlau stainless qib. Piv txwv li, AISI 316L sib raug rau US daim ntawv lo, thiab sus 316L sib raug rau Nyiv. Daim ntawv lo, peb lub teb chaws kev sib koom ua ke digital code yog S31603; los ntawm cov ntsiab lus ntawm kev pom, 304 tswj qhov kev tiv thaiv corrosion ntawm stainless hlau, hlau yuav tsum muaj ntau tshaj 18% chromium thiab ntau tshaj 8% npib tsib xee; 316L belongs rau 18-8 hom austenitic Derived steel qib ntawm bulk stainless hlau, nrog 2% mus rau 3% Mo cov khoom ntxiv; Tsis tas li ntawd, los ntawm qhov pom ntawm daim ntawv thov, 304 muaj cov txheej txheem zoo thiab kev sib txuas, thiab siv rau hauv cov khoom siv hauv tsev, chemistry, zaub mov kev lag luam, kev ua liaj ua teb thiab lwm yam. , Thiab cov corrosion kuj ntawm 316L muaj zog dua li ntawm 304, thiab nws yog ntau resistant rau corrosion nyob rau hauv kub kub ib puag ncig. Yog li ntawd, nyob rau hauv qhov kub thiab txias ib puag ncig, engineers feem ntau xaiv 316L cov khoom siv.
Raws li< kev="" tswj="" hwm="" tshuaj="" ntau="" lawm="">> (hloov ib tsab nyob rau hauv 2010), cov ntaub ntawv tsis tau hais tias qhov chaw ntawm cov khoom siv tshuaj nyob rau hauv kev sib cuag nrog cov ntaub ntawv yuav tsum yog stainless hlau 316L los yog 304, tab sis nws tsuas yog yuav tsum tau hais tias cov khoom siv yuav tsum tau txo kom txhob muaj kab mob sib kis thiab ncaj qha kev sib cuag. nrog tshuaj. Nws yuav tsum muaj corrosion kuj thiab lwm yam kev mob.
Ntawm lawv, "Txoj Cai 71" hais txog tias "kev tsim, xaiv, kev teeb tsa, kev hloov kho thiab tu cov cuab yeej yuav tsum ua raws li qhov xav tau, thiab kev pheej hmoo ntawm kev ua qias tuaj, kev sib kis, tsis meej pem thiab ua yuam kev yuav tsum raug txo kom ntau li ntau tau, thiab nws yuav tsum yooj yim rau kev khiav lag luam, ntxuav, tswj, thiab tswj. Ntxuav lossis sterilize thaum tsim nyog."
Tsis tas li ntawd, Tshooj 73 hais tias "cov cuab yeej tsim khoom yuav tsum tsis txhob muaj kev cuam tshuam rau cov tshuaj zoo. Qhov saum npoo ntawm cov khoom siv ncaj qha nyob rau hauv kev sib cuag nrog cov tshuaj yuav tsum tiaj tus, du, yooj yim los ntxuav los yog tshuaj tua kab mob, thiab corrosion-resistant, thiab yuav tsum tsis txhob chemically react los yog adsorb nrog tshuaj. Tshuaj los yog tso tshuaj rau hauv tshuaj."
Ntxiv rau qhov kev qhia tshwj xeeb no, qee cov neeg hauv kev lag luam kuj tau hais tias hais txog cov khoom siv stainless-steel, ISPE Baseline Guide khoom npaj muaj cov lus piav qhia no: Feem ntau, cov hlau tsis muaj hlau uas ncaj qha rau cov khoom siv yog 316L lossis siab dua. Stainless hlau uas tsis ncaj qha mus cuag cov khoom yuav tsum yog 306 los yog siab dua.
Hauv cov ntsiab lus, cov kev npaj tau hais los saum toj no thiab ISPE tsis muaj qhov yuav tsum tau ua rau cov ntaub ntawv stainless hlau. Raws li deb li cov tuam txhab siv tshuaj muaj kev txhawj xeeb, nws feem ntau yog nyob ntawm qhov tseeb ntawm cov khoom lag luam ntawm cov tuam txhab tshuaj.
Pharmaceuticals yog cov khoom tshwj xeeb ntsig txog kev noj qab haus huv thiab kev nyab xeeb ntawm tib neeg lub cev. Raws li kev lag luam, txhawm rau kom ntseeg tau tias cov tshuaj zoo thiab kev nyab xeeb, nws yog qhov zoo dua rau cov tuam txhab tsim khoom tsim nyog ua raws li cov qauv siab, cov kev xav tau siab, thiab xaiv cov khoom zoo los tsim. Txawm li cas los xij, yog tias muaj teeb meem tiag tiag, cov tuam txhab yuav tsum xav txog txhua qhov muaj peev xwm thaum txo lawv cov qauv tsim. Qhov kev pheej hmoo, xws li xeb, thiab lwm yam, txwv tsis pub nws yuav ua rau ntau tshaj qhov nce. Nyob rau hauv cov ntsiab lus ntawm kev txhim kho txuas ntxiv ntawm cov qauv kev lag luam kws tshuaj thiab kev saib xyuas nruj zuj zus, cov tuam txhab tshuaj yuav tsum nruj me ntsis ua raws li cov kev cai. Raws li kev lag luam cov cuab yeej siv tshuaj nce toj, lawv yuav tsum ua lawv qhov zoo tshaj plaws los tswj cov cuab yeej zoo los pab txhim kho kev lag luam tshuaj.
