Cov khoom siv xav tau thiab tsim cov ntsiab lus ntawm cov kws tshuaj tshuab
Taw qhia:
Peb ntseeg tias peb txhua tus yuav tsum paub cov khoom siv GMP. Cov ntaub ntawv ntawm cov tshuab siv tshuaj kws sib xyaw nrog cov tshuaj lossis cov txheej txheem tsim nyog' kev tswj hwm cov kev pheej hmoo yuav tsum yog non-toxic, corrosion-resistant thiab tsis poob tawm, thiab tsis txhob nti tawm lossis adsorb nrog cov tshuaj tsim tawm lossis cov txheej txheem tsim tawm. Lub chaw muag tshuaj homogenizer uas ua los ntawm Wuxi JKE emulsifying tshuab yog ua los ntawm 316L stainless hlau, uas tag nrho raws li GMP kev noj qab haus huv tus qauv ntawm cov tshuab tshuaj lag luam. Cov khoom muag zoo muag hauv kev lag luam kws kho mob hauv tsev thiab txawv teb chaws.
Cov khoom siv yuav tsum muaj
Kev kho mob homogenizercov khoom siv yuav tsum hais tias cov khoom sib txuas ntu yuav tsum yog hlau tsis xeb AISI 316L, thiab cov pa roj carbon ntsiab lus yuav tsum tsawg dua 0.02%. Thaum vuam ntawm 450 ~ 850 ° C, carbon thiab chromium hauv stainless hlau tuaj yeem tsim cov qib siab chromium carbide thiab ua rau lub zos chromium depletion, yog li txo qhov corrosion corrosion ntawm cov hlau. Yog li, cov hlau tsis muaj steel cov ntsiab lus tsawg yuav tsum siv cov kev lag luam kom ntau li ntau tau. Stainless hlau yog qhov txawv ntawm kev tsim ntawm nyias thiab muaj zog, nplua thiab ruaj khov nplua nuj oxide zaj duab xis (tiv thaiv zaj duab xis) los tiv thaiv kev nruam kev ua kom tsis tu ncua thiab oxidation ntawm oxygen atoms, yog li tau txais kev txhim kho corrosion. Yog hais tias cov yeeb yaj kiab ua kom tsis zoo, cov pa oxygen atoms hauv huab cua lossis kua yuav txuas ntxiv mus rau hauv cov hlau, cov hlau atoms yuav txuas ntxiv cais tawm thiab tsim xoob ntawm cov hlau tsis huv, thiab cov nplaim yuav txuas ntxiv xeb.
EPDM (ethylene propylene diene monomer), Viton (fluororubber), NBR (nitrile roj hmab), PTFE (polytetrafluoroethylene) thiab kal-rez (perfluoroelasticity roj hmab) yog txhua cov khoom ntim khoom kom tau raws li qib zaub mov ntawm FDA. EPDM muaj qhov kub thiab txias siab tshaj qhov siab, uas tuaj yeem siv ntawm 120 ° C rau lub sijhawm ntev thiab sib nrug ntawm 130 ~ 150 ° C; nws muaj zoo ua tsis taus pa, thiab kev ua tau zoo ntawm superheated chav ua hauj yog zoo dua li cov dej kub tsis kam, uas yog heev haum rau SIP tej yam kev mob; nws qhov kev txhim kho corrosion yog qhov zoo, thiab nws muaj cov tshuaj tiv thaiv zoo heev rau acids, alkalis thiab xab npum siv rau CIP tu. Viton tau tsim ua ntej los ntawm DuPont xyoo 1956. Nws muaj qhov kub tsis kam tiv thaiv (170 ° C ntawm FDA qib) thiab tshuaj lom neeg ua haujlwm tsis kam. NBR muaj cov roj ua tau zoo, tab sis qhov kub tsis kam tsuas yog nce mus txog 100 ° C. PTFE muaj qhov zoo tshaj plaws corrosion tsis kam, rwb thaiv tsev, siab thiab tsis kub tsis kam, tus kheej lubricating, tsis lo thiab atmospheric laus kuj, tab sis nws cov elasticity tsis zoo heev, yog li nws tsis tshua muaj siv hauv lub twj tso kua mis. Kalrez tuaj yeem yuav luag cov yam ntxwv thiab qhov kub siab xav tau ntawm cov khoom sib txawv hauv kev lag luam kev noj qab haus huv, thiab qhov siab ua haujlwm siab tshaj plaws yog 250 ° C.
Cov zaub mov qib sealing khoom siv
Hauv cov txheej txheem ntawm centrifugal twj tso kua mis ua, cov khoom siv lub tshuab nqus cov khoom siv tau ua raws cov qib zaub mov muaj xws li silicon carbide / silicon carbide, tungsten carbide / tungsten carbide, stainless hlau / tshwj xeeb carbon; cov khoom siv lub tshuab foob ua raws li qib kev kho mob suav nrog silicon carbide / silicon carbide thiab tungsten carbide / tungsten carbide. Lub foob siv tshuab nrog roj nplua nyeem tsis yog nrog tsim huv si. Txawm hais tias cov roj nplua nyeem yog qib zaub mov, nws yuav tsum tsis txhob ntxiv vim tias nws lub tswvyim tau tawm ntawm cov qauv tsim qauv ntawm cov twj huv.
Hais txog stamping
Stamping yog hais txog cov txheej txheem tsim cov txheej txheem ntawm stainless hlau phaj lossis profile los ntawm kev siv sab nraud los ntawm kev nias thiab tuag los tsim cov yas deformation lossis sib cais, thiaj li ua kom tau txais cov duab uas yuav tsum muaj thiab qhov loj ntawm qhov haujlwm (ntu ib feem); forging yog hais txog cov txheej txheem ua nyob rau hauv uas cov hlau tsis xeb thov siv nrog lub siab thiab ua cov qauv duab uas yuav tsum muaj los ntawm yas kev deformation, Qhov kev quab yuam no tau tiav los ntawm kev siv lub hammers lossis siab, thiab cov txheej txheem forging tsim cov qauv txheej tuab ua ke thiab txhim kho cov yam ntxwv lub cev ntawm hlau stainless. Nruab nrab lub siab thiab forging koom nrog yas ua, sib xyaw hu ua forging. Forging qhov chaw muaj lub zog ntau dua, sab hauv cov lus yog ntau dua, tsis muaj qhov ntxeem tau thiab rov ua qhov chaw, tsawg dua kev sib xyaw lossis lwm qhov kev ua kom tsis zoo, nws qhov saum npoo du yog siab dua, thiab nws yooj yim dua kom tau raws li cov kws xav tau rau saum npoo roughness ntawm sterile twj tso kua mis. Ua li no, kev kho mob homogenizer tsim tawm muaj tus qauv zoo thiab zoo.
