Yuav ua li cas calibrate lub tshuab cua tshuab yog tias lub herringbone clamp los yog traction roller tsis ua raws li qhov nruab nrab ntawm lub tshuab taub hau?

 

Lub hauv paus ntsiab lus ntawm kev tsis sib haum xeeb: Hauv kev tsim cov yeeb yaj kiab tshuab, qhov kev sib raug zoo ntawm herringbone fixture thiab cov kab nruab nrab ntawm traction roller ncaj qha cuam tshuam qhov zoo ntawm cov yeeb yaj kiab. Thaum qhov sib txawv ntawm ob thiab kab nruab nrab ntawm lub taub hau tuag ntau tshaj 0.5 hli, zaj duab xis yuav ua rau pom kev cuam tshuam kev ntxhov siab thaum lub sij hawm tensile txheej txheem. Qhov kev faib tsis sib xws ntawm kev ntxhov siab tuaj yeem ua rau oscillations tsis tu ncua thiab, nyob rau hauv cov xwm txheej hnyav, kauv distortion ntawm zaj duab xis npuas. Kev sim cov ntaub ntawv qhia tau hais tias rau txhua txhua 1 hli sib txawv, qhov transverse thickness fluctuation tus nqi ntawm cov zaj duab xis nce los ntawm 12% -15%, uas ua rau txo qis ntawm cov khoom tsim nyog tus nqi. Nyob rau hauv ib lub tuam txhab cov kab ntau lawm, piv txwv li, tus nqi seem vim qhov nruab nrab misalignment yog siab li 18% ua ntej calibration thiab poob qis dua 3% tom qab calibration.
Cov txheej txheem tsis raug

1. Ntug thickness anomaly: Thaum lub thickness sib txawv cov npoo ntawm cov zaj duab xis yog ntau tshaj 15 microns, ib tug "wavy edge" tshwm sim thaum winding. Qhov no wavy ntug deformation tsis tsuas yog cuam tshuam rau cov tsos ntawm cov khoom, tab sis kuj txo cov ntu ntu kev ua tau zoo los ntawm ntau dua 30%.
2. Deg Stripe Defect: Tsis sib npaug siab ntawm cov traction rollers yuav ua rau longitudinal kab txaij ntawm zaj duab xis nto. Qhov kev tsis zoo no tshwj xeeb tshaj yog tshwm sim hauv kev tsim cov yeeb yaj kiab pob tshab, uas coj ncaj qha mus rau kev txo qis ntawm cov khoom.
3. Risk ntawm membrane npuas rupture: Deviation ntawm lub kaum sab xis ntawm lub herringbone clamp yuav ua rau ib tug txo nyob rau hauv daim nyias nyias npuas stability. Kev txheeb xyuas los ntawm ib lub tuam txhab qhia tau hais tias rau txhua qhov kev sib txawv ntawm lub kaum sab xis ntxiv, qhov kev sib tsoo ntau zaus nce 300%, txwv tsis pub muaj kev tsim khoom ntxiv.
