I. Kev Ntsuam Xyuas Kev Pom Kev Ua Ntej (Kev Txiav Txim Siab)
Ua raws li tus qauv teeb pom kev zoo (piv txwv li, D65 hnub ci qhov chaw):
Tso cov ntaub dyed thiab cov qauv qauv ntaub ntawm ib sab, ua kom lawv zoo sib xws thiab kaw ua ke;
Saib qhov pom ntawm qhov deb ntawm 30-50cm, tsom rau:
Xaus-rau-Xaum Xim Qhov Sib Txawv: Tshawb xyuas seb cov xim qhov tob zoo ib yam ntawm qhov pib thiab qhov kawg ntawm cov ntaub yob;
Ntug-rau-Center Colour Difference: Kos rau "dub nruab nrab, sib dua ntug" lossis "dub ntug, sib dua nruab nrab" tshwm sim ntawm sab laug, nruab nrab, thiab sab xis;
Pem hauv ntej-rau-Rov qab Xim Qhov txawv (Ntxhais Duab Ntxoo thiab Lub Teeb): Tig cov ntaub thiab txiav txim siab seb cov xim ntawm ob sab yog tib yam;
Batch-rau-Batch Colour Difference: Txheeb xyuas qhov sib txawv tseem ceeb hauv tib xim ntawm cov xim sib txawv los yog xim qhov tob.
⚠️ Ceeb Toom: Tsis txhob txiav txim nyob rau hauv lub teeb pom kev zoo tib yam lossis ncaj qha tshav ntuj kom tiv thaiv kev cuam tshuam thiab kev txiav txim tsis raug.
II. Precise Instrument Measurement (Quantitative Judgment)
Siv lub spectrophotometer rau scientifically quantify cov xim, outputting tus nqi ΔE (tag nrho cov xim txawv) rau lub hom phiaj thiab traceable nrhiav tau.
Kev ntsuas qhov chaw: Ib qho tsib - txoj kev ntsuas qhov taw qhia yog siv - tsib ntsiab lus ntawm sab laug, nruab nrab, sab xis, thiab ob qho kawg ntawm cov ntaub.
ΔE Tus Nqi Txiav Txim Siab:
ΔE < 1: Pom tau yuav luag tsis muaj qhov sib txawv, txais tau;
1 Tsawg dua lossis sib npaug rau ΔE < 2: Qhov sib txawv me ntsis, feem ntau lees txais;
2 Tsawg dua lossis sib npaug rau ΔE < 3.5: Qhov sib txawv tseem ceeb, cov neeg siv khoom lees paub yuav tsum tau tso tawm;
ΔE Ntau dua lossis sib npaug rau 3.5: Cov xim sib txawv tseem ceeb, yuav tsum suav tias tsis tuaj yeem lees txais thiab rov ua haujlwm dua.
Piv txwv li: Ib pawg ntawm polyester npuag ntsuas ΔE=4.0. Txawm hais tias nws tsis tau raws li tus qauv seem, nws tau dhau qhov kev kam rau siab ntawm tus neeg siab siab - kawg. Ntxiv kev kho mob dyeing yog pom zoo.
III. Grey Scale Rating Method (Industry Standard) Kev sib piv yog ua raws li GB250-1995 "Grey Scale for Assessing Color Change":
Cov qauv ntaub yuav raug kuaj yog muab tso rau sab - los ntawm - sab nrog cov nplai grey nyob rau hauv qhov chaw teeb pom kev zoo;
Ob lossis ntau tus neeg soj ntsuam nws tus kheej tau qhab nia tus qauv, thiab qib nruab nrab raug coj mus kuaj;
Qib 4 lossis siab dua yog suav tias yog 合格 (tsim nyog), thiab qib qis dua 4 yog suav tias muaj xim sib txawv.
IV. Online Dynamic Monitoring (Intelligent Trend) Ib lub qhov muag pom kev sib txawv tau qhia, uas tuaj yeem txheeb xyuas cov xim sib txawv ntawm lub sijhawm tiag tiag nrog qhov tseeb ntawm 99.3%, txhawb lub tswb tsis siv neeg thiab cov ntaub ntawv kaw;
Ua ke nrog AI algorithms los kwv yees dyeing deviations, cov txheej txheem tsis tuaj yeem cuam tshuam ua ntej txhawm rau txhim kho batch stability.
