Lub zog sib txuas ntawm corrugated cardboard yog hais txog qhov sib cais siab tshaj plaws uas daim ntawv saum npoo, cov ntawv hauv ob sab phlu lossis cov ntawv tseem ceeb thiab cov corrugated ncov tuaj yeem tiv taus tom qab corrugated cardboard yog sib koom. GB/T6544-2008 Daim Ntawv Ntxiv B qhia tias lub zog nplaum yog lub zog uas yuav tsum tau cais lub tshuab raj raj ntev ntawm corrugated cardboard nyob rau hauv cov kev xeem ntawv teev tseg. Kuj hu ua tev lub zog, qhia hauv Newtons ib meter (Leng) (N / m). Nws yog ib qho tseem ceeb ntawm lub cev kom muaj nuj nqis uas qhia txog qhov zoo ntawm corrugated cardboard bonding, thiab yog ib qho ntawm cov kev qhia tseem ceeb rau kev ntsuam xyuas lub cev lub cev ntawm corrugated thawv. Kev sib raug zoo zoo tuaj yeem txhim kho lub zog compressive, ntug compressive zog, puncture zog thiab lwm yam kev ntsuas lub cev ntawm cov thawv corrugated. Yog li ntawd, qhov tseeb ntawm kev sib khi lub zog tau dhau los ua ib feem tseem ceeb ntawm kev tshuaj xyuas zoo ntawm cov thawv corrugated, thiab nws yog ib qho tsim nyog yuav tsum tau hais txog qhov no, txhawm rau ua kom muaj kev txiav txim siab tseeb ntawm seb qhov zoo ntawm cov thawv corrugated puas tsim nyog lossis tsis tau.
Lub hauv paus ntsiab lus ntawm kev ntsuam xyuas ntawm corrugated cardboard daim ntawv cog lus lub zog yog muab cov koob-zoo li tus accessory ntawm lub corrugated cardboard thiab nto (sab hauv) daim ntawv ntawm tus qauv (los yog ntawm lub corrugated cardboard thiab nruab nrab cardboard), thiab ces nias lub koob-zoo li tus accessory. ntxig nrog tus qauv. , ua kom nws ua cov lus sib txheeb kom txog thaum nws sib cais los ntawm qhov sib cais. Lub sijhawm no, qhov sib cais siab tshaj plaws uas lub ncov corrugated thiab lub ntsej muag daim ntawv los yog lub ncov corrugated thiab cov ntaub ntawv hauv ob sab phlu thiab cov ntawv tseem ceeb suav nrog yog xam los ntawm cov qauv, uas yog tus nqi ntawm lub zog. Kev siv lub zog tensile yog tsim los ntawm kev ntxig rau sab sauv thiab qis ntawm cov corrugated rods, yog li qhov kev sim no tseem hu ua tus pin bonding zog test. Cov cuab yeej siv yog lub zog compressive tester, uas yuav tsum tau ua raws li cov kev cai ntawm cov compressive zog tester teev nyob rau hauv GB / T6546. Cov khoom siv coj mus kuaj yuav tsum ua raws li lub tshuab txiav thiab cov cai teev tseg hauv GB / T6546. Cov ntawv txuas yog tsim los ntawm sab sauv ntawm qhov txuas thiab qhov qis ntawm qhov txuas, thiab nws yog ib qho khoom siv uas siv lub siab sib xws rau txhua qhov nplaum ntawm cov qauv. Txhua feem ntawm cov ntawv txuas muaj xws li tus pin-hom daim thiab ib qho kev txhawb nqa uas tau muab tso rau hauv nruab nrab ntawm qhov chaw corrugated cardboard, thiab qhov sib txawv ntawm qhov sib txawv ntawm tus pin-hom daim thiab cov khoom txhawb nqa yuav tsum tsawg dua 1%.
Kev xeem txoj kev rau cov nplaum nplaum: Ua qhov kev sim ua raws li qhov yuav tsum tau muaj ntawm Daim Ntawv Ntxiv B "Kev Txiav Txim ntawm Adhesion Strength of Corrugated Cardboard" hauv lub teb chaws tus qauv GB / T 6544-2008. Kev ntsuas cov qauv yuav tsum tau ua raws li GB / T 450. Kev tuav thiab kuaj cov qauv thiab ib puag ncig yuav tsum tau ua raws li qhov xav tau ntawm GB / T 10739, thiab qhov kub thiab av noo yuav tsum tau txiav txim siab nruj. Kev npaj ntawm cov qauv yuav tsum txiav 10 ib leeg corrugated cardboard, los yog 20 ob corrugated cardboard los yog 30 triple corrugated cardboard (25 ± 0.5) mm × (100 ± 1) mm qauv ntawm cov qauv, thiab cov kev taw qhia corrugated yuav tsum zoo ib yam li cov qauv. luv sab kev taw qhia. Zoo ib yam. Thaum lub sij hawm xeem, thawj zaug muab cov qauv coj mus kuaj rau hauv cov khoom siv, ntxig cov koob-zoo li cov khoom siv nrog ob kab ntawm cov hlau rods ntawm cov ntawv saum npoo thiab cov ntawv tseem ceeb ntawm cov qauv, thiab ua kom cov kab ntawv txhawb nqa, saib xyuas kom tsis txhob muaj kev puas tsuaj. tus qauv, raws li qhia hauv daim duab hauv qab no. Qhia. Tom qab ntawd muab tso rau hauv nruab nrab ntawm lub qis platen ntawm lub compressor. Pib lub compressor thiab nias qhov txuas nrog cov qauv ntawm qhov ceev ntawm (12.5 ± 2.5) mm / min kom txog thaum lub ncov thiab daim ntawv ntsej muag (los yog hauv ob sab phlu / nruab nrab daim ntawv) sib cais. Sau qhov tso tawm siab tshaj plaws rau qhov ze tshaj 1N. Kev sib cais qhia ntawm sab xis hauv daim duab hauv qab no yog kev sib cais ntawm cov ntawv corrugated thiab cov ntawv hauv ob sab phlu. Tag nrho ntawm 7 koob tau muab tso rau, sib cais 6 corrugations zoo. Rau ib qho corrugated cardboard, sib cais quab yuam ntawm cov ntawv saum toj kawg nkaus thiab cov ntawv corrugated, thiab cov ntawv corrugated thiab cov ntawv hauv ob sab phlu yuav tsum tau sim 5 zaug raws li, thiab tag nrho ntawm 10 zaug; Lub zog sib cais ntawm daim ntawv, cov ntawv nruab nrab thiab cov ntawv corrugated 2, corrugated ntawv 2 thiab cov ntawv hauv ob sab phlu yog ntsuas 5 zaug txhua, tag nrho ntawm 20 zaug; peb-corrugated cardboard yuav tsum tau ntsuas 30 zaug nyob rau hauv tag nrho. Muab xam tus nqi nruab nrab ntawm qhov sib cais quab yuam ntawm txhua txheej nplaum, tom qab ntawd xam cov nplaum lub zog ntawm txhua txheej nplaum, thiab thaum kawg siv qhov tsawg kawg nkaus tus nqi ntawm cov nplaum nplaum ntawm txhua txheej nplaum raws li cov nplaum lub zog ntawm cov corrugated board, thiab khaws cov txiaj ntsig. mus rau peb tus lej tseem ceeb. .
