Ntim cov khoom tshuaj xyuas | Yam khoom kuaj lub cev yuav tsum tau ua rau cov khoom ntim khoom kom zoo nkauj

Cov tshuaj pleev ib cecov khoom ntimsuav nroglub raj mis yas, iav fwj, hoses, thiab lwm yam. Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv thiab haum rau cov tshuaj pleev ib ce nrog cov textures sib txawv thiab cov khoom xyaw. Qee cov tshuaj pleev ib ce muaj cov khoom xyaw tshwj xeeb thiab xav tau ntim tshwj xeeb los xyuas kom meej cov haujlwm ntawm cov khoom xyaw. Tsaus iav fwj, lub tshuab nqus tsev twj, hlau hoses, thiab ampoules feem ntau yog siv ntim tshwj xeeb.

Test yam: barrier zog

Cov khoom pov thawj ntawm kev ntim khoom yog ib qho ntawm cov khoom siv tseem ceeb rau kev ntim khoom kom zoo nkauj. Barrier zog hais txog kev cuam tshuam ntawm cov khoom ntim ntawm cov pa roj, kua thiab lwm yam permeates. Barrier zog yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom thaum lub sij hawm txee lub neej.

Unsaturated bonds hauv cov khoom xyaw kom zoo nkauj yog yooj yim oxidized ua rancidity thiab deterioration. Kev poob dej tuaj yeem ua rau cov tshuaj pleev ib ce kom qhuav thiab tawv. Nyob rau tib lub sijhawm, kev saib xyuas cov ntxhiab tsw ntxhiab hauv cov tshuaj pleev ib ce kuj tseem ceeb heev rau kev muag cov tshuaj pleev ib ce. Kev ntsuas kev ua tau zoo muaj xws li ntsuas qhov permeability ntawm cov ntim tshuaj pleev ib ce rau oxygen, dej vapor, thiab cov pa roj tsw qab.

Test yam khoom barrier zog

1. Oxygen permeability test. Qhov ntsuas no tsuas yog siv rau kev ntsuas oxygen permeability ntawm cov yeeb yaj kiab, cov yeeb yaj kiab sib xyaw, cov hnab ntim khoom kom zoo nkauj lossis lub raj mis siv rau kev ntim khoom kom zoo nkauj.

2. Kev ntsuas dej vapor permeability. Nws yog tsuas yog siv rau kev txiav txim siab ntawm cov dej vapor permeability ntawm cov khoom siv tshuaj pleev ib ce thiab cov ntim ntim xws li lub raj mis, hnab, thiab cov kaus poom. Los ntawm kev txiav txim siab ntawm cov dej vapor permeability, cov kev qhia ntawm cov khoom xws li cov khoom ntim tuaj yeem tswj tau thiab hloov kho kom tau raws li qhov sib txawv ntawm cov khoom siv.

3. Fragrance preservation Performance test. Qhov ntsuas no tseem ceeb heev rau cov tshuaj pleev ib ce. Thaum cov tshuaj tsw qab ntawm cov tshuaj pleev ib ce ploj lossis hloov pauv, nws yuav cuam tshuam rau kev muag khoom. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau sim cov tshuaj tsw qab preservation kev ua tau zoo ntawm cov tshuaj pleev ib ce ntim.

Cov khoom xeem: Kev xeem muaj zog

Txoj kev ntsuas lub zog muaj xws li cov cim qhia xws li lub zog tensile ntawm cov khoom ntim cov khoom tsim cov ntaub ntawv, tev lub zog ntawm cov yeeb yaj kiab sib xyaw, lub zog hluav taws xob, lub zog tsim kua muag, thiab kev sib tsoo. Peel zog tseem hu ua composite system zog. Nws yog los ntsuam xyuas lub zog sib txuas ntawm cov khaubncaws sab nraud povtseg hauv cov yeeb yaj kiab sib xyaw. Yog tias qhov kev sib txuas ntawm lub zog yuav tsum muaj tsawg dhau, nws yooj yim heev los ua kom tawg thiab lwm yam teeb meem xws li kev sib cais ntawm cov khaubncaws sab nraud povtseg thaum siv lub ntim. Thaum tshav kub kub foob lub zog yog kuaj lub zog ntawm lub foob. Thaum lub sijhawm khaws cia thiab kev tswj xyuas kev thauj mus los ntawm cov khoom, thaum lub tshav kub foob lub zog tsawg dhau lawm, nws yuav ncaj qha ua rau muaj teeb meem xws li tawg ntawm lub tshav kub foob thiab cov khoom xau. Puncture resistance yog ib qho qhia txog kev pheej hmoo ntawm kev ntim khoom los tiv thaiv kev sib tsoo los ntawm cov khoom tawv.

Kev ntsuas lub zog yuav siv lub tshuab ntsuas hluav taws xob tensile. Lub tshuab tensile ntawm nws tus kheej tsim thiab tsim los ntawm Shandong Puchuang Industrial Technology Co., Ltd. tuaj yeem ua tiav ntau yam kev sim (lub zog tensile, tev lub zog, puncture kev ua tau zoo, lub zog tsim kua muag, thiab lwm yam) tib lub sijhawm; lub tshav kub foob tester tuaj yeem kuaj xyuas qhov ntsuas kub ntawm lub zog thiab lub zog sealing ntawm cov khoom ntim.

Cov khoom kuaj: Thickness test

Thickness yog lub peev xwm qhia tau yooj yim rau kev sim cov yeeb yaj kiab. Kev faib tawm tsis sib xws yuav tsis tsuas yog cuam tshuam ncaj qha rau lub zog tensile thiab thaiv cov khoom ntawm cov yeeb yaj kiab, tab sis kuj cuam tshuam rau kev txhim kho thiab ua cov yeeb yaj kiab tom qab.

Txawm hais tias lub thickness ntawm cov khoom ntim cov tshuaj pleev ib ce (zaj duab xis los yog daim ntawv) yog qhov sib xws yog lub hauv paus rau kev sim ntau yam khoom ntawm zaj duab xis. Cov yeeb yaj kiab tsis sib xws yuav tsis tsuas yog cuam tshuam rau lub zog tensile thiab cov khoom thaiv ntawm cov yeeb yaj kiab, tab sis kuj cuam tshuam rau cov txheej txheem tom ntej ntawm zaj duab xis.

Muaj ntau txoj hauv kev rau kev ntsuas thickness, uas feem ntau muab faib ua cov tsis sib cuag thiab kev sib cuag: hom tsis sib cuag muaj xws li hluav taws xob, eddy tam sim no, ultrasonic, thiab lwm yam .; kev sib cuag hom kuj tseem hu ua mechanical thickness ntsuas hauv kev lag luam, uas tau muab faib ua qhov chaw sib cuag thiab qhov chaw sib cuag.

Tam sim no, lub chaw soj nstuam ntawm lub thickness ntawm cov tshuaj pleev ib ce films txais cov neeg kho tshuab nto tiv tauj txoj kev xeem, uas kuj yog siv raws li ib tug arbitration txoj kev rau thickness.

Cov khoom kuaj: ntim cov foob kuaj

Lub sealing thiab to detection ntawm cov ntim tshuaj pleev ib ce yog hais txog cov yam ntxwv ntawm lub hnab ntim khoom kom tsis txhob muaj lwm yam khoom nkag los lossis cov ntsiab lus ntawm kev khiav tawm. Muaj ob txoj hauv kev uas siv los tshawb nrhiav:

Test yam Thickness test

1. Dej decompression txoj kev:

Cov txheej txheem xeem yog raws li hauv qab no: muab cov dej distilled tsim nyog rau hauv lub tshuab nqus tsev, muab cov qauv tso rau hauv lub tshuab nqus tsev thiab muab tso rau hauv qab lub phaj siab kom lub pob tag rau hauv dej; Tom qab ntawd teeb tsa lub tshuab nqus tsev siab thiab lub sijhawm ntawm qhov kev sim, pib qhov kev xeem, tshem tawm lub tshuab nqus tsev, thiab ua kom cov qauv rau hauv dej ua kom muaj qhov sib txawv sab hauv thiab sab nraud, saib xyuas cov pa tawm hauv cov qauv, thiab txiav txim siab qhov kev sib khi ua haujlwm ntawm lub tshuab nqus tsev. qauv.

2. Txoj kev ntsuas siab zoo:

Los ntawm kev siv lub siab mus rau sab hauv ntawm lub pob, lub siab tsis kam, sealing degree thiab to index ntawm cov pob mos raug kuaj, thiaj li ua tiav lub hom phiaj ntawm kev sim nws txoj kev ncaj ncees thiab sealing lub zog.
