Hauv kev tsim cov hnab yas ntim, pob tshab yas, thiab lwm thaj chaw, thiab yog li ntawd muaj cov kev xav tau zoo heev. Txhawm rau kom ntseeg tau tias cov khoom lag luam raws li cov neeg siv khoom thiab cov kev soj ntsuam cov kev soj ntsuam cov kev kuaj xyuas kom nruj yog qhov yuav tsum ua thaum tsim khoom.
1. Pom kev tshuaj xyuas
Cov kev kuaj txheem ntau lawm yog tshuaj xyuas thawj zaug pom:
Transparency: lub hnab yuav tsum pom meej thiab pob tshab, dawb ntawm pom kev tsis txaus siab lossis npuas;
Flatness: lub hnab saum npoo yuav tsum yog tus, dawb ntawm cov creases, wrinkles, lossis khawb;
Ntug sealing: cov npoo yuav tsum ncaj, dawb ntawm burrs, xoob ntsaws, lossis qhib;
Luam Ntawv: Yog luam tawm, kuaj xyuas cov xim clarity, kev sib xws, thiab xim fading.
2. Dimension thiab thickness ntsuas
Siv tus caliper, micrometer, lossis hluav taws xob thoj
Kev kam: feem ntau tsis pub dhau ± 2mm;
Thickness uniformity: ntsuas ntawm ntau qhov chaw kom tsis txhob muaj thaj chaw ntawm ntau dhau los yog tuab tuab.
3. Tensile thiab thauj khoom -} kev ntsuas cov kabmob
Txhawm rau txheeb xyuas lub zog ntawm lub hnab, kev ntsuas lub cev ua haujlwm tau ua:
Tensile Kuaj: Lub Tensile Lub Zog ntawm lub hnab ntim thiab cov npoo muag tau sim ntawm lub tshuab kuaj sim siab tshaj plaws.
Kev Ntsuas Cov Khoom: Lub hnab ntim tau nrog lub cev hnyav, nqa lossis dai, thiab tshuaj xyuas kom tawg lossis qhib.
4. Seem thiab to feakage
Kev sib khi ntawm cov hnab yas pob tshab yog qhov tseem ceeb, tshwj xeeb tshaj yog rau khoom noj ntim khoom:
Cov dej tso chaw: ib qho nyiaj ntawm cov dej ntxiv rau lub hnab, sab laug sawv ntsug sawv ntsug lossis maj mam shaken, kom saib rau txi.
Foob Lub Zog Kev Ntsuas: Lub foob yog rub los xyuas nws txoj kev ruaj ntseg.
5. Kev Kuaj Xyuas Kev Nyab Xeeb thiab Kev Nyab Xeeb Kev Nyab Xeeb
Zaub mov -} bead pob tshab yas hnab kuj xav tau kev sim kev sim siab:
Kuaj xyuas cov npoo ntawm lub hnab rau kev nyiam huv thiab qhov tsis muaj hmoov av thiab tsw.
Yog tias tsim nyog, lub hnab xa mus rau ib tus thib peb {{}} tog tog kev kuaj xyuas kom meej raws li cov qauv kev sib tiv tauj.
6. Kuaj zaus thiab cov txheej txheem
Cov kev ntsuam xyuas cov qauv feem ntau ua rau lub sijhawm ua tiav khoom, thaum ua tiav khoom lag luam, thiab ua ntej ua zaub mov xa tuaj. Ib tug naj npawb ntawm lub hnab muaj piv txwv los ntawm txhua pob rau kev sim. Yog tias tus nqi tsis ua tiav tau ntau tshaj li cov nyiaj uas muaj cai, cov pob yuav tsis tsim nyog tsis tsim nyog thiab yuav xav tau kev ua haujlwm lossis kiav txhab.
Kev kuaj cov hnab yas ua kom pom cov khoom yas pom kev, kev kuaj pom ntawm lub cev, xau {}}} kev tshuaj ntsuam thiab kev tshuaj xyuas kev nyab xeeb. Qhov kev tshawb fawb nyuaj no tsis tsuas yog ua kom tau tias cov khoom tau raws cov qauv zoo tab sis tseem tuaj yeem lav tus neeg siv cov neeg siv tau zoo thiab ua kom muaj kev nyab xeeb thiab ntseeg tau tias nyob rau hauv lub lag luam kawg.
