Cov thawv ntawv corrugated, raws li cov khoom ntim cov ntawv zoo tib yam, cov khoom ntim khoom ntim rau ntau tshaj 30 feem pua ntawm kev lag luam ntim. Raws li nws cov yam ntxwv thiab ib puag ncig zoo, nws yog dav siv nyob rau hauv lub ntim txheej ntawm ntau yam khoom thiab yog inseparable ntawm peb lub neej thiab ntau lawm. Piv txwv li, lub thawv ntim cov thawv ntim yog cov khoom siv dav tshaj plaws ntawm lub thawv hauv kev thauj mus los thiab khaws cia. Corrugated thawv yog tus nqi qis, ruaj khov, thiab ib puag ncig tus phooj ywg. Txawm li cas los xij, tsis yog txhua lub thawv tsim muaj sib npaug. Uas tau hais tias, lawv sib txawv hauv ntau yam xws li compressive zog, thickness, tshuaj tsis haum, thiab lwm yam. yog li ntawd. Kev tshawb pom ntawm txhua yam ntawm lub zog ntsuas ntawm lub thawv corrugated yog qhov tseem ceeb los xyuas kom meej cov khoom zoo thiab kev ua haujlwm zoo.
Txhawm rau txiav txim siab seb lub thawv corrugated tiv thaiv cov kev cuam tshuam sab nraud - los pab koj txiav txim siab thaum xaiv cov thawv - cov neeg tsim khoom siv ntau cov txheej txheem kuaj. Qhov no yog muab tso ua ke ntawm feem ntau siv corrugated thawv xeem txoj hauv kev los xyuas lub zog ntawm corrugated thawv.
01 Kev tshuaj xyuas qhov zoo
Cov thawv ntawv corrugated tsim nyog yuav tsum tau luam tawm cov qauv, cov ntawv sau meej, tsis muaj kab tawg thiab ploj lawm; qauv chromaticity zoo ib yam, ci, thiab ci, thiab qhov chaw luam ntawv yuam kev yog me me, qhov yuam kev ntawm lub thawv loj yog nyob rau hauv 7 hli, thiab qhov yuam kev ntawm lub thawv me me yog nyob rau hauv 4 hli.
Qhov zoo ntawm lub thawv corrugated yuav tsum tsis muaj kev puas tsuaj thiab stains. Rau cov duab ntawm lub thawv, lub siab ntev ntawm lub puab txoj kab uas hla ntawm lub thawv thiab tsim dimension yuav tsum tau khaws cia nyob rau hauv ± 5 hli rau lub thawv loj thiab ± 3 hli rau lub thawv me me, thiab tag nrho qhov ntev yog qhov tseem ceeb tib yam. Lub flap ntawm lub thawv corrugated yuav tsum tau qhib thiab kaw 180 degrees thiab folded ntau tshaj 5 zaug. Tag nrho qhov ntev ntawm cov kab nrib pleb nyob rau hauv txheej txheej thiab sab hauv txheej ntawm thawj- thiab thib ob-chav cartons, thiab sab hauv txheej ntawm lub thawv thib peb yuav tsum tsis txhob ntau tshaj 70 hli. Tsis tas li ntawd, nws tseem yuav tsum tau hais tias lub thawv lub cev sib koom ua ke yog tus qauv, thiab cov npoo zoo huv si, tsis muaj qhov sib tshooj, thiab lwm yam.
02 Edge Crush Strength Test (ECT)
Lub ntug compression lub zog yog lub siab uas ib qho piv txwv ntawm ib qho dav tuaj yeem tiv taus ntawm ib chav tsev ntev, thiab nws hais txog lub peev xwm los tiv thaiv lub siab sib npaug mus rau corrugated kev taw qhia. Ntug siab yog txoj hauv kev zoo tshaj plaws los ntsuas lub zog ntawm daim ntawv corrugated. Nws ncaj qha cuam tshuam rau kev txhawb nqa lub zog ntawm corrugated thawv. Los ntawm ntug kev ntsuas lub zog ntawm cov thawv corrugated, peb tuaj yeem nkag siab txog qhov muaj peev xwm ntawm cov ntawv corrugated hauv cov thawv corrugated.
03 Kev ntsuam xyuas lub zog tawg
Lub zog tawg ntawm cov thawv corrugated yog hais txog qhov sib npaug ntawm qhov siab max siab perpendicular rau saum npoo ntawm cov qauv uas daim ntawv los yog duab los qhia tuaj yeem tiv taus ib cheeb tsam hauv kev sim. Qhov kev ntsuam xyuas no yog los tshuaj xyuas lub peev xwm ntawm lub thawv kom tiv taus qhov chaw zoo li qub hauv qhov chaw thauj mus los.
Kev ntsuas lub zog tawg ntawm cov thawv corrugated tuaj yeem siv los nkag siab txog lub peev xwm ntawm lub thawv kom tiv thaiv kev tuav, thauj khoom thiab tshem tawm, cuam tshuam, thiab rhuav tshem lub zog thaum lub sijhawm ncig. nruab nrab daim ntawv), thiab tsis muaj dab tsi ua nrog cov ntawv corrugated hauv nruab nrab.
04 Puncture Strength Test
Lub zog puncture yog kev ua haujlwm ua los ntawm lub pyramid ntawm ib qho duab los ntawm cov duab los qhia, uas yog, kev ua haujlwm yuav tsum tau pib qhov puncture thiab tsim kua muag thiab khoov cov duab los qhia rau hauv lub qhov, qhia hauv joules (J). Ntsuam xyuas lub zog uas cov thawv corrugated tuaj yeem tiv thaiv kev cuam tshuam sab nraud.
Kev ntsuas lub zog ntawm cov thawv corrugated tuaj yeem nkag siab qhov cuam tshuam ntawm lub thawv thaum siv lossis kev thauj mus los, thiab qhov kev ntsuam xyuas qhia txog qhov tsis kam ntawm corrugated cardboard rau qhov cuam tshuam ntawm cov khoom ntse. Lub zog puncture yog ze ze rau fiber ntau toughness, hardness, nruj, noo noo cov ntsiab lus ntawm lub hauv paus ntawv, lub zog ntawm lub corrugated board thiab thickness ntawm lub corrugated board.
05 Bonding zog Test
Corrugated box bonding zog yog hais txog lub zog uas yuav tsum tau cais cov kev sib txuas ntawm corrugated cardboard ib chav tsev ntev raws li qhov kev sim ntsuas, qhia hauv Newtons ib meter (N / m).
Lub zog sib txuas ntawm cov thawv corrugated tuaj yeem siv los nkag siab qhov nruj thiab ruaj khov ntawm kev sib txuas ntawm corrugated cardboard ntsej muag daim ntawv thiab cov ntawv tseem ceeb. Yog tias nws tsis ruaj khov, nws yuav cuam tshuam rau lub zog ntawm corrugated cardboard. Nws yog ib qho yooj yim rau tev tawm ntawm cov khaubncaws sab nraud povtseg thaum siv, uas yuav ncaj qha ua rau lub poob siab tsis kam thiab compression tsis kam ntawm lub thawv tiav raug txo, thiab cov khoom tsis tuaj yeem tiv thaiv zoo dua.
06 Compressive zog test
Lub zog compressive yog hais txog qhov siab tshaj plaws tus nqi uas lub thawv corrugated tuaj yeem tiv taus thaum lub thawv khoob corrugated muab tso rau peb-dimensionally thiab ob sab yog nias ntawm qhov ceev tsis tu ncua.
Qhov kev sim no tuaj yeem nkag siab txog qhov siab tshaj plaws tus nqi uas cov thawv corrugated tuaj yeem tiv taus, thiab ntsuas seb lub thawv puas tuaj yeem tiv taus qhov hnyav txaus thiab seb nws puas tuaj yeem tiv thaiv cov ntsiab lus ntawm cov khoom, thiaj li tiv thaiv kev siv, tuav, stacking, thiab lwm yam. pob khoom vim tsis muaj zog. Qhov tshwm sim ntawm undesirable phenomena xws li cov khoom deformation thiab kev puas tsuaj thaum lub sij hawm cia thiab kev thauj mus los kuj yog ib qho kev nthuav qhia ntawm kev txheeb xyuas qhov kev tiv thaiv kev ua tau zoo ntawm corrugated thawv.
07 Kev ntsuas dej permeability
Cov dej tsis kam ntawm cov thawv corrugated tsom rau cov dej nqus dej ntawm daim ntawv lossis cov duab los qhia saum npoo. Qhov kev sim no tuaj yeem nkag siab txog cov ntsiab lus noo noo uas lub thawv tuaj yeem thaiv nyob rau hauv kev cuam tshuam ntawm ib puag ncig sab nraud. Nws tuaj yeem ua pov thawj los ntawm cov dej vapor kis tus nqi uas cov dej vapor kis tau tus nqi qis, qhia tias cov khoom siv corrugated cardboard muaj cov dej noo zoo. Qhov chaw tsim khoom, chaw cia khoom, ib puag ncig siv, huab cua, huab cua thiab lwm yam ntawm corrugated thawv yuav cuam tshuam rau lub thawv. Txhawm rau kom ntseeg tau lub zog compressive ntawm lub thawv, qhov cuam tshuam ntawm qhov chaw sab nraud ntawm lub thawv yuav tsum zam kom ntau li ntau tau. WVTR ntsuas ntsuas tuaj yeem muab cov ntaub ntawv cuam tshuam ncaj qha rau koj lub thawv corrugated tam sim no txhua lub sijhawm.
