Yuav ua li cas thiaj daws tau qhov teeb meem ntawm ces kaum thiab tawg thaum lub sijhawm ua cov thawv xim lub thawv ntawv corrugated

Qhov teeb meem ntawm ces kaum thiab tawg thaum lub sij hawm txiav tuag, sib txuas lub thawv xa ntawv, thiab cov txheej txheem ntim khoom ntawm cov thawv xim feem ntau ua teeb meem rau ntau lub tuam txhab ntim khoom thiab luam ntawv. Tom ntej no, cia peb saib cov txheej txheem kev tswj hwm ntawm cov neeg ua haujlwm laus rau cov teeb meem zoo li no.

1. Kev nias tsis raug ua rau tawg

1.1 Muaj tej yam txawv teb chaws nyob rau hauv qhov indentation groove ntawm lub phaj hauv qab, ua rau muaj kev nce siab ntawm lub zog thaum lub sijhawm txiav tuag. Qhov no yog ib qho ua rau tawg hauv kev tsim khoom. Nws tuaj yeem ua rau tag nrho cov kab tsaus nti tawg, ua rau cov khoom pov tseg.lub thawv khoom plig ntawv

1.2 Qhov khiav tawm, uas txhais tau hais tias lub phaj txiav tuag lossis hauv qab tau muab tso rau hauv qhov chaw kom cov hlau hlau poob rau sab nraud ntawm qhov indentation groove. Qhov tawg los ntawm qhov laj thawj no feem ntau yog tsom mus rau cov kab tsaus nti hauv tib qho kev taw qhia, uas yog vim tsis muaj kev sib haum xeeb ntawm rab riam txiav lossis indentation thiab tus qauv ntoo, ua rau muaj kev hloov pauv hauv qab kev siab.lub thawv rau khoom

Qhov kev xaiv ntawm cov hlau hlau tuab thiab qhov dav ntawm qhov indentation groove tsis phim cov ntaub ntawv ntawv. Raws li qhov yuav tsum tau ua ntawm cov txheej txheem txiav tuag, cov hlau hlau sib txawv yuav tsum tau siv rau ntau hom ntawv, nrog rau cov tuab sib txawv ntawm cov phaj hauv paus thiab cov dav sib txawv ntawm cov kab zais. Yog tias tsis phim, nws yooj yim ua rau cov kab zais tawg.

2. Kev tawg los ntawm cov txheej txheem tsim cov phaj txiav tuag

2.1 Kev tuav txoj haujlwm hlau tsis raug lossis cov burrs tshuav thaum txiav cov hlau hlau thaum lub sijhawm tsim cov phaj txiav tuag. Yog tias cov khoom tau dhau los ua kev kho saum npoo ntawm kev txiav tuag, xws li lamination. Cov burrs tshuav ntawm cov hlau hlau thaum lub sijhawm txiav tuag tuaj yeem ua rau lub zog tensile ntawm zaj duab xis saum npoo puas tsuaj, thiab zaj duab xis tsis tuaj yeem tiv taus lub zog thaum lub sijhawm tsim khoom, ua rau tawg.

2.2 Cov riam hlau thiab cov hlau ntawm kab tsaus ntuj muaj ib rab riam thiab qhov sib tshuam. Vim yog qhov tsis sib xws ntawm qhov sib tshuam, kev rhuav tshem yuav tshwm sim thaum txiav tuag.

Thaum lub ntaub phuam ntawm rab riam nias hlau tsis nyob hauv qhov chaw tsim nyog, qhov nias hlau yuav tawg, thiab qhov deformation thiab kev puas tsuaj ntawm rab riam nias hlau kuj tseem tuaj yeem ua rau qhov nias hlau tawg.

Puas yog kev sib xyaw ua ke ntawm riam thiab hlau ntawm pwm riam tsim nyog. Tshwj xeeb tshaj yog thaum tus qauv tsim tsis xav txog qhov tuab ntawm daim ntawv, qhov sib tshooj ntawm riam thiab kab tsis tuaj yeem zam tau zoo, thiab kev cuam tshuam tshwm sim thaum lub sijhawm pwm, ua rau muaj kev sib sau ua ke ntawm lub zog ntau dhau ntawm qhov no thiab qhov tshwm sim ntawm kev tawg.

3. Cov teeb meem zoo ntawm cov khoom siv

3.1 Yog tias cov dej hauv daim ntawv qis dhau, daim ntawv yuav tawg yooj yim. Qhov xwm txheej no feem ntau tshwm sim thaum lub caij ntuj no, vim tias huab cua qhuav thiab txias, thiab qhov av noo hauv huab cua qis, uas cuam tshuam ncaj qha rau cov dej noo ntawm daim ntawv cardboard, ua rau daim ntawv cardboard tawg tom qab nias. Feem ntau, cov dej noo ntawm daim ntawv hauv paus raug tswj hwm hauv qhov txwv siab tshaj (ntawm 8% -14%);

3.2 Cov ntaub ntawv lamination ntawv: Cov zaj duab xis polypropylene uas ncab ob sab muaj qhov sib txawv me ntsis, ua rau lub zog tensile txo qis. Lamination yog ib txoj kev kho qhov chaw rau ntawv, feem ntau yog ua los ntawm BOPP zaj duab xis. Yog tias zaj duab xis BOPP puas ua ntej txiav tuag, nws yuav ua rau zaj duab xis BOPP tsis tuaj yeem tiv taus lub zog thiab tawg thaum khoov tom qab txiav tuag. Zaj duab xis tawg tsuas yog tshwm sim hauv txheej zaj duab xis, thiab thaum lub zog nce ntxiv, nws yuav nthuav dav raws qhov kev tawg. Txheej hauv qab ntawm daim ntawv tsis tawg, qhia tias nws tsis muaj feem cuam tshuam nrog daim ntawv. Yog tias zaj duab xis tsis tawg thiab daim ntawv twb tawg lawm, nws tsis muaj feem cuam tshuam nrog zaj duab xis thiab muaj teeb meem nrog daim ntawv.

3.3 Kev taw qhia ntawm daim ntawv tsis raug. Thaum txiav tuag, yog tias qhov kev taw qhia ntawm cov hlau hlau indentation yog perpendicular rau qhov kev taw qhia ntawm cov ntawv fibers, uas yuav ua rau radial puas tsuaj rau cov ntawv fibers, cov kab tsaus nti yuav yooj yim khoov, tsim zoo, thiab lub kaum sab xis me me; Yog tias cov hlau hlau indented yog sib luag rau qhov kev taw qhia ntawm cov ntawv fiber thiab daim ntawv tsis puas tsuaj kab rov tav, cov hlau tsaus nti tsis yooj yim khoov thiab tsim rau hauv lub ces kaum puag ncig nrog lub kaum sab xis loj, uas muaj lub zog txhawb nqa ntawm txheej sab nraud ntawm daim ntawv thiab yooj yim tawg. Qhov kev taw qhia ntawm daim ntawv muaj kev cuam tshuam me ntsis rau kev txiav tuag ntawm cov khoom ntawv ib daim ntawv, tab sis nws tsis yooj yim rau tawg kab vim yog kev pwm tsis zoo. Txawm li cas los xij, nws muaj kev cuam tshuam loj rau cov khoom siv daim npav. Yog tias tsis ua haujlwm kom zoo, tsis yog tsuas yog kev pwm tsis zoo, tab sis nws kuj yooj yim rau tawg kab. Qhov laj thawj tseem ceeb yog tias cov kab tsaus nti sib luag rau cov ntawv nplej tawg kab hauv ntau qhov chaw sib txawv, thaum lwm qhov kev taw qhia tsis ua.

3.4 Kev teeb tsa corrugation siab dhau. Lub zog tawg thiab lub zog sib nqus ntawm lub nplhaib transverse ntawm daim ntawv hauv paus yog ib qho ntawm cov yam cuam tshuam. Yog tias qhov kev tiv thaiv folding ntawm daim ntawv sab hauv qis dhau, nws kuj tuaj yeem ua rau tawg yooj yim.

3.5 Lub pwm tau siv ntev dhau lawm. Tom qab siv lub phaj txiav tuag ntev ntev hauv kev txiav tuag, rab riam nias hlau yuav xoob, ua rau rab riam nias hlau dhia thaum lub sijhawm txiav tuag, ua rau cov hlau ntawv nias tawg. Vim yog siv lub roj hmab ntev ntev, qhov siab tsis sib npaug ntawm lub ncoo ua rau txoj kab siab tawg.
