Ua kom cov qauv zoo sib xws hauv ntau yam kev ua kom tsis muaj menyuam sib xyaw ua ke ntawm kev siv cov khoom siv raw los ntawm tib pawg, ua haujlwm sib koom ua ke molding txheej txheem, thiab kev tswj hwm pab pawg. Cov kev siv tshwj xeeb yog raws li hauv qab no:
1. Siv Raw Materials los ntawm Tib Batch: Tag nrho cov qauv xeem yuav tsum yog los ntawm raw cov ntaub ntawv los ntawm tib lub ntau lawm batch kom tshem tawm qhov kev ua tau zoo hloov pauv los ntawm qhov sib txawv ntawm qhov hnyav molecular, cov ntsiab lus ntxiv, lossis impurities.
Xav kom cov neeg muag khoom muab COA (Certificate of Analysis) thiab MSDS (Material Safety Data Sheet) rau cov khoom ntawd los xyuas kom meej cov ntaub ntawv tsis raug.
2. Unified Txhaj Moulding Txheej Txheem: Npaj cov qauv siv tib yam khoom, pwm, thiab cov txheej txheem tsis. Cov ntsiab lus tseem ceeb ntawm kev tswj hwm muaj xws li:
Melt Kub: Hloov hauv ± 5 degree
Kev Txhaj Tshuaj: Ua kom tsis tu ncua
Lub Sijhawm Txias: Tsis txhob ua kom txias tsis sib xws ua rau muaj kev ntxhov siab sab hauv
Qhuav ua ntej-kev kho mob: Qhuav tag nrho cov ntaub ntawv raw ntawm 120℃rau 4-6 teev kom tsis txhob ya raws los ntawm kev cuam tshuam kev ua haujlwm.
Kev pom zoo: Siv cov tshuab txhaj tshuaj molding tshuab kom txo tau tib neeg kev ua yuam kev thiab txhim kho rov ua dua.
3. Cov txheej txheem ua pab pawg thiab Randomization
Dual-Dimensional Coding Management: Cov qauv raug suav raws li "sterilization round + test item" (piv txwv li, G1-ME, EO2-CHEM) los tiv thaiv kev tsis meej pem.
Random Assignment: Lub tshuab hluav taws xob random yog siv los muab cov qauv rau txhua pawg sim kom tsis txhob muaj kev tsis ncaj ncees.
Kev teeb tsa Duplicate Samples: Yam tsawg kawg 10 qhov piv txwv duplicate yog npaj rau txhua pab pawg rau kev txheeb xyuas txheeb cais thiab tshem tawm qhov tsis zoo.
