Dawb cardboard rau ntim luam yeeb yuav tsum muaj siab tawv, tawg kuj, smoothness thiab whiteness. Daim ntawv saum npoo yuav tsum tau tiaj tus, tsis pub muaj kab txaij, pob, pob, warping thiab deformation ntawm tiam. Raws li cov luam yeeb pob nrog dawb cardboard. Kev siv lub vev xaib high-speed gravure tshuab luam ntawv luam tawm, yog li cov ntawv dawb cardboard nro qhov ntsuas qhov xav tau siab. Lub zog tensile, tseem hu ua tensile lub zog los yog lub zog tensile, yog txhais tau tias yog qhov siab tshaj plaws uas daim ntawv tuaj yeem tiv taus thaum lub sijhawm tawg, qhia hauv kN / m. High-speed gravure tshuab luam ntawv los rub cov ntawv yob, high-speed luam ntawv los tiv thaiv kev nro ntau dua, yog tias qhov tshwm sim ntawm cov ntawv tsis tu ncua, raug khi ua rau tsis tu ncua, txo kev ua haujlwm, tab sis kuj ua rau cov ntawv poob.
Muaj ob homdawb cardboard rau ntim luam yeeb, ib qho yog FBB (yellow core white cardboard) thiab lwm qhov yog SBS (dawb core white cardboard), ob qho tib si FBB thiab SBS tuaj yeem siv rau cov ntim luam yeeb yog ib sab coated dawb cardboard.
FBB muaj peb txheej ntawm pulp, sab saum toj thiab hauv qab txheej siv sulfate ntoo pulp, thiab cov tub ntxhais txheej siv tshuaj mechanically hauv av ntoo pulp. Sab pem hauv ntej (sab luam ntawv) yog coated nrog ib txheej txheej uas yog siv ob lossis peb squeegees, thaum sab nraub qaum tsis muaj txheej txheej. Txij li thaum nruab nrab txheej siv tshuaj thiab mechanically hauv av ntoo pulp, uas muaj ib tug siab yield rau ntoo (85% mus rau 90%), ntau lawm cov nqi kuj tsis tshua muaj, thiab yog li ntawd tus nqi muag ntawm qhov tshwm sim.FBB daim duabyog tus qis. Lub pulp no muaj fiber ntau ntev thiab tsawg dua cov fibers zoo thiab cov pob fiber ntau, ua rau cov tuab zoo ntawm cov ntawv tiav, yog li FBB ntawm tib cov grammage yog tuab dua li SBS, uas feem ntau muaj peb txheej ntawm cov ntaub so ntswg, nrog sulphur- bleached ntoo pulp siv rau lub ntsej muag, core, thiab rov qab txheej. Sab pem hauv ntej ((sab luam ntawv)) yog coated, thiab zoo li FBB kuj coated nrog ob los yog peb squeegees, thaum sab nraud tsis muaj txheej txheej. Txij li cov txheej txheem tseem siv bleached sulfate ntoo pulp, nws muaj ntau dua whiteness thiab yog li ntawd hu ua dawb core white card. Nyob rau tib lub sijhawm, cov ntaub ntawv fiber ntau zoo, daim ntawv yog nruj dua, thiab SBS yog thinner dua li qhov tuab ntawm FBB ntawm tib grammage.
Cigarette card, los yogdawb cardboardrau luam yeeb, yog ib qho zoo coated dawb cardboard tshwj xeeb uas siv los ua cov khoom ntim luam yeeb. Cov ntawv tshwj xeeb no tau ua tiav thiab ua tiav zoo los ntawm cov txheej txheem nruj, thiab nws lub luag haujlwm tseem ceeb yog muab cov luam yeeb zoo nkauj, huv si thiab tiv thaiv cov khoom ntim sab nraud. Raws li ib feem tseem ceeb ntawm cov khoom lag luam luam yeeb, daim npav luam yeeb tsis tsuas yog ua tau raws li cov kev xav tau ntawm cov khoom ntim khoom, tab sis kuj paub txog cov khoom lag luam zoo tshaj plaws ntawm cov khoom lag luam vim nws qhov tshwj xeeb kev kho mob thiab luam ntawv tsim nyog.
Nta
1. Khoom siv thiab ntau.
Daim npav luam yeeb muaj ntau npaum li cas, feem ntau siab dua 200g / m2, uas ua kom cov tuab txaus thiab lub zog los txhawb thiab tiv thaiv cov luam yeeb hauv.
Nws cov qauv fiber ntau yog qhov sib xws thiab ntom ntom, ua los ntawm cov ntoo zoo nkauj, thiab ntxiv cov khoom ntim thiab cov nplaum los xyuas kom meej tias daim ntawv yog ob qho tib si nyuaj thiab muaj kev ua haujlwm zoo.
2. Txheej thiab calendering.
Cov txheej txheem calendering ua rau qhov chaw tiaj tus thiab du, txhim kho qhov tawv thiab glossiness ntawm daim ntawv, thiab ua rau lub ntsej muag ntawm cov ntawv luam yeeb ntau dua qib siab.
3. Physicochemical zog.
Daim npav luam yeeb tau zoo heev folding thiab tearing kuj, kom tsis txhob tawg nyob rau hauv high-speed automated ntim txheej txheem. Nws muaj qhov nqus tau zoo thiab ziab kom zoo rau tus number case, uas yog qhov zoo rau kev luam ntawv sai thiab tiv thaiv tus lej nkag.
Nws ua tau raws li cov kev cai ntawm kev nyab xeeb khoom noj khoom haus, tsis muaj ntxhiab tsw thiab tsis muaj tshuaj lom neeg lub cev, uas tiv thaiv kev nyab xeeb ntawm cov neeg siv khoom.
4. Kev tiv thaiv ib puag ncig thiab tiv thaiv kev ua txhaum cai.
Nrog rau kev paub txog kev tiv thaiv ib puag ncig, kev tsim daim npav luam yeeb niaj hnub nyiam siv cov peev txheej txuas dua tshiab thiab txo cov pa phem ib puag ncig.
Qee cov khoom lag luam luam yeeb hauv high-end kuj tseem koom nrog kev siv thev naus laus zis los tiv thaiv kev ua lag luam, xws li cov txheej txheem tshwj xeeb, cov xim muaj xim, cov qauv laser, thiab lwm yam., txhawm rau tiv thaiv qhov teeb meem loj zuj zus ntawm kev cuav.
Daim ntawv thov
Rigid lub thawv ntim: Siv rau hauv kev tsim khoom ntawm ntau hom ntawm cov thawv luam yeeb, cov txheej sab hauv kuj tseem yuav laminated nrog aluminium ntawv ci thiab lwm yam ntaub ntawv los ua kom cov khoom thaiv. Cov pob mos: Txawm hais tias tsis tshua muaj, cov ntawv luam yeeb kuj tseem siv tau los ua cov ntaub los yog kaw hauv qee cov pob muag ntawm cov luam yeeb.
Branding: Los ntawm kev luam ntawv zoo thiab tsim tshwj xeeb, cov ntawv luam yeeb pab cov tuam txhab luam yeeb nthuav tawm lawv cov duab thiab txhim kho kev lag luam kev sib tw.
Cov kev cai lij choj thiab kev tswj hwm: Nrog cov kev cai nruj zuj zus ntawm kev ntim luam yeeb hauv ntau lub teb chaws, cov ntawv luam yeeb kuj yuav tsum tau ua raws li qhov yuav tsum tau ua kom cov lus ceeb toom txog kev noj qab haus huv pom meej thiab nyuaj rau kev cuam tshuam.
