Thaum muab khoomkev lag luam cov ntaub so ntswg-txawm yog nkauj xwbntoo pulp ntawm daim tawv nqaij, xyoob daim ntawv tso quav tso quav, los yoghnyav -cov ntaub ntawv siv dua tshiabcov phuam da dej-B2B cov neeg yuav khoom thiab OEM cov tswv lag luam tsis tuaj yeem tso siab rau ntawm qhov chaw- qib handfeel ib leeg. Kev txiav txim siab cov qauv ntsuas zoo yuav tsum muaj kev sim kuaj xyuas nruj, ntsuas ntsuas tus qauv, thiab kev tswj xyuas qhov zoo (QC) cov txheej txheem.
Thaum lub sij hawm soj ntsuam los yog thov kev soj ntsuam, pawg neeg yuav khoom ntsuam xyuas zeb kev ua tau zoo nyob rau hauv plaub lub ntsiab lub cev tsis: absorbency, ntub lub zog, tensile zog, thiab softness. Ntawm no yog li cas cov ntawv pov thawj mills ntsuas thiab siv cov ntaub so ntswg zoo siv thoob ntiaj teb ISO / ASTM cov qauv ntsuas.
1. Dej Absorbency Rate & Capacity (ISO 12625-8)
Absorbency txiav txim siab kev ua haujlwm hauv kev lag luam daim ntawv phuam thiab napkins. Peb ntsuas ob qhov ceev ntawm cov kua uptake thiab tag nrho lub peev xwm nqus.
Standard Protocol:TS EN ISO 12625-8 (Cov ntaub so ntswg thiab cov khoom siv ntaub so ntswg - Ntu 8: Dej- lub sijhawm nqus thiab dej-kev nqus dej, txoj kev ntsuas pob tawb-immersion).
Cov cuab yeej Lab:Automated Basket Immersion Tester thiab Digital Precision Analytical Balance (0.001g raug).
QC xeem txheej txheem:Ib qho 5g cov ntaub so ntswg tau muab ntim rau hauv ib lub pob tawb xaim, muab tso rau hauv dej distilled ntawm 23℃± 1 degree, thiab teem sij hawm kom txog thaum ua tiav ntub dej (Txoj Kev Ntsuas, ntsuas hauv vib nas this). Tom qab ntawd lub pob tawb raug tshem tawm rau 60 vib nas this kom ntws dej dawb, ua raws li qhov hnyav los xam tag nrho cov dej loj tuav ib gram ntawm fiber ntau (g / g Capacity).
OEM Specification Lub Hom Phiaj:Cov ntaub ntawv zoo tshaj plaws tsom qhov nqus nrawm hauv qab 2.5 vib nas this thiab muaj peev xwm tshaj 7.0 g / g.
2. Tensile Strength: Qhuav Tensile Peak (ISO 12625-4)
Qhuav tensile lub zog tiv thaiv tearing thaum lub sij hawm siab - hloov pauv ceev, ntim kab khiav tau, thiab kawg - neeg siv xa tawm.
Standard Protocol:TS EN ISO 12625-4 Kev txiav txim siab ntawm lub zog tensile, ncab ntawm lub zog siab tshaj plaws thiab lub zog tensile absorption
Cov cuab yeej Lab:Tus nqi tsis tu ncua ntawm Elongation (CRE) Universal Tensile Tester nrog pneumatic grips.
QC xeem txheej txheem:Test strips (50 mm dav, 100 mm gauge length) raug txiav nyob rau hauv ob qho tib si Machine Direction (MD) thiab Hla Direction (CD). Cov cuab yeej CRE rub lub sawb ntawm qhov nrawm nrawm (50 mm / min) kom txog thaum kev ua haujlwm tsis ua haujlwm.
Qhov tseem ceeb Metric:Tensile Performance index qhia hauv N / m lossis kN / m, nrog rau MD / CD tensile ratio. Qhov sib npaug MD / CD piv (feem ntau yog 1.5: 1 txog 2: 1) tiv thaiv kev tawg ntxov ntxov raws kab perforation.
3. Wet Tensile Strength & ntub dej -rau -Dry Ratio (ISO 12625-5)
Rau cov phuam da dej hauv chav ua noj, cov ntaub so hauv tsev, thiab cov ntaub ntub dej - siv cov ntaub so ntswg, lub zog ntub dej yog qhov tseem ceeb los tswj cov txheej txheem kev ncaj ncees thaum saturated.
Standard Protocol:TS EN ISO 12625-5 Kev txiav txim siab ntub tensile zog siv Finch khob apparatus
Cov cuab yeej Lab:Tensile Tester nruab nrog lub tshuab hluav taws xob Finch Cup txuas.
QC xeem txheej txheem:Cov ntaub so ntswg tau muab khi ib ncig ntawm ib lub pas nrig hlau hauv Finch Cup thiab submerged hauv dej distilled rau 15 vib nas this (los yog txog li 2 teev rau ntub - lub zog resin validation). Qhov ntsuas ntsuas lub zog xav tau los rhuav tshem cov qauv wetted.
B2B Kev Ntsuas Zoo:Lub zog ntub dej yog xam raws li feem pua ntawm lub zog tensile qhuav. Kev lag luam ntub dej- cov phuam da dej muaj zog feem ntau xav tau 15% mus rau 25% ntub / qhuav qhov sib piv, ua tiav los ntawm ntub- cov khoom ntxiv dag zog (PAAE resins).
4. Lub Hom Phiaj Softness Metrics (Tissue Softness Analyzer / ASTM D6828)
Handfeel yog qhov tsis txaus ntseeg, ua rau kev soj ntsuam tus neeg muag khoom nyuaj thaum lub Hoobkas tshawb xyuas. Niaj hnub no cov ntaub so ntswg mills hloov vaj huam sib luag handfeel xeem nrog lub hom phiaj acoustic thiab mechanical ntsuas.
Standard Protocol:ASTM D6828 (Txoj Kev Xeem Txheej Txheem rau Kev Nyuaj Ntawm Fabric-Type Materials) nrog rau TSA (Tissue Softness Analyzer) tsis muaj.
Cov cuab yeej Lab:Emtec TSA (Tissue Softness Analyzer).
QC xeem txheej txheem:Cov qauv yog clamped, thiab ib tug rotating hniav siv micro- vibrations rau saum npoo. Acoustic sensors sau ob qhov sib txawv:
TS 7 Peak (dB):Ntsuas qhov softness tiag tiag (micro-roughness/fiber softness). Cov nqi qis dua dB qhia tau tias qhov chaw mos.
TS 750 Peak (dB):Ntsuas tag nrho cov qauv nruj / qhov yooj yim.
Daim ntawv thov kev lag luam:Siab -kawg 3-ply lub ntsej muag cov ntaub so ntswg lub hom phiaj TS7 cov qhab nia qis dua 12 dB, ntsuas qhov ntom ntom ntom nrog softness.
Factory QC raws tu qauv:Hauv -Cov Txheej Txheem Kab Tswj & Ntau Ntau Yam
Txhawm rau kom paub meej batch-rau-batch sib xws rau cov ntaub ntawv ntiag tug tsim khoom thiab cov khoom lag luam wholesale, peb lub Hoobkas ua haujlwm nruj ntau-theem QC workflow:
Raw Material Inspection:Cov khoom siv hluav taws xob tsis zoo, cov khoom siv rov ua dua tshiab, lossis xyoob cov ntaub ntawv pov thawj tau txais kev tshuaj xyuas cov dej noo (ISO 287) thiab cov khoom siv fiber ntau faib ua ntej pulping.
Jumbo Roll Test:Txhua tus niam txiv yob uas tsim los ntawm cov ntaub so ntswg tshuab yog kuaj tam sim ntawd rau GSM qhov hnyav (ISO 12625-6), caliper thickness, qhuav tensile, thiab ci ntsa iab (ISO 2470).
Hloov kab ntawv pov thawj: Perforation lub zog, embossing txhais, ply bonding zog, thiab daim ntawv suav precision yog saib xyuas txhua txhua 30 feeb.
Ua ntej-Shipment Audit (AQL 1.5/4.0): Cov khoom tiav tiav raug kuaj pom qhov kawg, qhov ntev, thiab lub cev tsis zoo ua ntej tsim daim ntawv pov thawj ntawm Kev Ntsuam Xyuas (CoA) rau cov thawv xa khoom.
Kev koom tes nrog ISO 9001 tau lees paubcov ntaub so ntswg manufacturersnrog cov cuab yeej kuaj xyuas tag nrho tshem tawm qhov tsis zoo, txo cov neeg siv khoom tsis txaus siab, thiab ua kom yooj yim rau koj cov txheej txheem kev tshuaj xyuas. Hu rau peb pawg neeg ua haujlwm engineering kom thov cov ntaub ntawv kuaj xyuas lub Hoobkas, kev cai GSM specifications, lossis OEM cov khoom siv coj mus kuaj.
