Kev Tswj Xyuas Zoo Rau Cov Khoom Siv Raw
Supplier Audit
Los ntawm kev ntsuam xyuas cov kev tsim nyog, lub koob npe nrov thiab muaj peev xwm ntawm cov neeg muag khoom, peb tshuaj xyuas cov neeg muag khoom tsim nyog. Qhov no tuaj yeem txo qhov kev pheej hmoo ntawm kev yuav khoom thiab tus nqi tsis zoo ntawm cov khoom siv raw li ntawm 5 - 15%.
Raw Khoom Txais
- Tshuaj muaj pes tsawg leeg:Tshawb xyuas nws cov tshuaj muaj pes tsawg leeg kom ntseeg tau tias nws ua tau raws li cov qauv siv.
- Lub cev muaj zog:Ntsuas qhov ntom ntom, melting point, tensile lub zog, thiab lwm yam ntawm cov khoom siv raw.
- Zoo Zoo:Txheeb xyuas qhov tsis xws luag ntawm cov khoom siv raw, xws li tawg, npuas, impurities, thiab lwm yam.
Kev txheeb xyuas cov khoom sib xyaw
Peb siv cov cuab yeej xws li spectrometers thiab chromatographs los soj ntsuam thiab sib piv nrog cov kev cai ntawm cov qauv tsim los txiav txim siab ntau yam khoom thiab lawv cov ntsiab lus hauv cov khoom siv raw. Tom qab ntawd, peb tuaj yeem kho cov qauv hauv lub sijhawm.
Kev kuaj lub cev
- Tensile Testing Tshuab:Nws yog siv los ntsuas lub zog tensile thiab elongation ntawm kev tawg ntawm cov khoom siv raw.
- Hardness Tester:Nws ntsuas qhov hardness ntawm cov khoom siv raw.
- Densitometer:Nws kuaj qhov ntom ntawm cov khoom siv raw.
Thermal Properties Testing
Kev ntsuas cov cuab yeej cua sov yog hais txog kev soj ntsuam cov ntsiab lus melting thiab thermal stability ntawm cov ntaub ntawv los ntawm txoj kev xws li kev ntsuas thermogravimetric. Vim tias lawv yuav tsum tiv thaiv deformation nyob rau hauv ib puag ncig thermal.
Chemical Resistance Test
Muab cov ntaub ntawv tso rau hauv cov tshuaj sib txawv thiab saib xyuas lawv cov kev hloov pauv thiab kev ua haujlwm poob. Tsuas yog cov ntaub ntawv soj ntsuam los ntawm kev sim tuaj yeem zam kev xeb hauv cov txheej txheem ntawm kev kho dej phwj tuaj.
Batch Consistency Check
Ua piv txwv thiab sib piv ntawm ntau qhov ntsuas kev ua tau zoo ntawm ntau pawg ntawm cov khoom siv raw kom tsis txhob muaj qhov hloov pauv zoo thaum lub sijhawm tsim khoom.
Kev Tswjhwm Zoo rau Kev Tsim Khoom
Ntau lawm parameter hloov
Ua ntej pib tsim khoom, AquaSust cov kws tshaj lij yuav teeb tsa qhov kub thiab txias, siab, lub sijhawm thiab lwm yam tsis zoo ntawm cov cuab yeej tsim khoom raws li tus qauv. Piv txwv li, nyob rau hauv MBBR ntau lawm, cov tshuaj tiv thaiv kub yog feem ntau teem ntawm 180 degree thiab 200 degree, thiab cov tshuaj tiv thaiv lub sij hawm yog guaranteed yog 3 teev. Qhov no tso cai rau cov khoom siv raw yuav tsum ua kom tiav, thiab lub zog thiab porosity ntawm cov khoom tiav ua tau raws li cov qauv.
Khoom siv calibration
Calibrate cov cuab yeej tseem ceeb tsis tu ncua. Piv txwv li, siv lub siab calibrator los ntsuas lub siab kom nws ruaj khov ntawm 80MPa thiab 100MPa. Qhov ntsuas no tuaj yeem ua kom cov molding zoo thiab qhov ruaj khov ntawm cov khoom. Kev tswj tsis raug tam sim no nyob rau hauv ± 5A thiab qhov hluav taws xob yuam kev tswj tsis pub dhau ± 2V tuaj yeem tiv thaiv qhov tsis xws luag xws li vuam txias thiab xau vuam.
Thawj daim tshuaj ntsuam xyuas
Thaum pib ntawm txhua batch ntawm ntau lawm, thawj cov khoom raug tshuaj xyuas, xws li qhov siab, txoj kab uas hla thiab lwm qhov ntev. Nyob rau tib lub sijhawm, nws cov tsos yuav tsum du, tsis muaj qhov pom tseeb khawb, qhov pores thiab lwm yam tsis xws luag, thiab xim yuav tsum zoo ib yam.
Cov txheej txheem tswj
Thaum lub sijhawm tsim khoom, teeb tsa ntau qhov kev tshuaj xyuas zoo. Piv txwv li, rau MBBR cov khoom, peb feem ntau ua random soj ntsuam txhua 5 khoom. Qhov hnyav ntawm cov khoom coj mus kuaj yuav tsum nyob rau hauv tus qauv hnyav ± 3g, thiab lub zog compressive yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntau dua lossis sib npaug rau 8MPa.
Kev tshuaj xyuas cov khoom tiav
Tom qab tag nrho cov khoom tiav lawm, lawv tau soj ntsuam tag nrho raws li cov qauv tshuaj xyuas cov khoom tiav. Piv txwv li, cov aeration diffusers yuav tsum tau mus kuaj corrosion kuj, uas yog, tom qab tau muab tso rau hauv 5% sodium chloride tov rau 72 teev, yuav tsum tsis muaj cov cim pom tseeb ntawm corrosion ntawm qhov chaw ua ntej lawv tuaj yeem ntim thiab muab tso rau hauv. khaws cia.
Cov ntsiab lus kuaj zoo

Nws tag nrho raus cov khoom nyob rau hauv ib tug aqueous tov uas simulates kev ua hauj lwm tej yam kev mob ntawm ib tug bioreactor, thiab siv ib tug quab yuam sensor los ntsuas lub buoyancy nws raug. Los ntawm kev sib piv nrog cov theoretical xam tus nqi, nws txiav txim siab seb lawv puas tuaj yeem raug tshem tawm ruaj khov thiab tswj tau lub xeev zoo.
5. Compressive Strength Test:
Ntawm lub tshuab kuaj khoom siv thoob ntiaj teb, axial siab yog siv rau cov khoom ntawm tus nqi thauj khoom ua ntej kom txog thaum cov khoom raug puas los yog mus txog qhov deformation. Qhov no tuaj yeem txheeb xyuas tau tias lawv tuaj yeem tiv taus qhov sib thooj hauv kev siv tiag tiag.
6. Kev Ntsuas Qhov Chaw:
Qhov tshwj xeeb thaj chaw ntawm cov khoom yog ntsuas los ntawm cov pa adsorption los xyuas kom meej tias lawv tuaj yeem muab qhov chaw txuas txaus rau cov kab mob kom loj hlob biofilms.
7. Chemical Resistance Test:
Nyob rau lub sij hawm no, peb yuav tsum tau tsau cov khoom nyob rau hauv acidic, alkaline thiab salty wastewater kho tshuaj nruab nrab daws feem. Tom qab lub teeb kub thiab lub sij hawm, coj nws tawm thiab xyuas qhov hnyav thiab qhov loj ntawm cov khoom hloov los ntsuas nws cov corrosion kuj.
8. Abrasion Resistance Test:
Hauv cov kauj ruam no, peb ua cov khoom lag luam thiab cov khoom siv sib txhuam tshwj xeeb raug kuaj xyuas kev sib txhuam ntawm lub zog, ceev thiab mob stroke. Tom qab ntawd, ntsuas qhov hnav ntawm cov khoom thiab saib xyuas qhov hnav ntawm qhov chaw.
9. Kev kuaj kev laus:
Muab cov khoom tso rau hauv qhov ntsuas kev laus nrawm kom simulate ib puag ncig tej yam kev mob xws li kub, av noo, thiab lub teeb thaum siv mus sij hawm ntev, thiab ua qhov kev ntsuam xyuas kev laus rau qee lub sijhawm. Tom qab ntawd peb sib piv nws lub zog, qhov ntom ntom, thiab zoo li qub nrog rau yav dhau los los soj ntsuam nws cov kav ntev.
