1. Warp ntawm Custom Paper Jewelry Boxes

Feem ntau, muaj 6 hom corrugated board warping deformation, feem ntau yog:

1. Warping kab rov tav

Yog vim li cas yog: cov dej noo ntawm cov ntawv hauv paus yog siab dhau (los yog cov ntsiab lus noo ntawm lub ntsej muag yog tsawg); Cov dej ntau dhau hauv ib qho corrugated bonding; Nyob rau hauv, qhov ntau npaum li cas ntawm lub ntsej muag daim ntawv yog zoo heev.

Kev daws: (1) nce qhov winding ntawm daim ntawv ntawm lub tshuab ziab khaub ncaws ntawm ib sab; (2) txo qhov winding nto ntawm daim ntawv sab hauv ntawm ob txheej preheater; (3) kaw ib feem ntawm lub tiaj lub tshuab ziab khaub ncaws; (4) txhim kho kev khiav ceev ntawm lub tshuab sib xyaw; (5) Txo cov kis ntawm cov squeezer yob, lub sizing yob thiab qis dua corrugated yob, thiab txo cov nyiaj lizing ntawm ib sab corrugated; (6) Hloov daim ntawv uas hnyav tshaj qhov yuav tsum tau ya raws.

2. Kab rov tav down warping

Yog vim li cas yog: cov dej noo ntawm cov ntawv hauv paus yog siab dhau; Tsis zoo li qhov kub thiab qhov nrawm ntawm qhov chaw cua sov.

Kev daws: (1) nce cua sov winding nto ntawm lub ntsej muag daim ntawv ntawm ob txheej preheater; (2) kev siv cov nplaum nrog cov viscosity zoo, txo cov kua nplaum ntawm lub tshuab ua ke; (3) txo qhov winding nto ntawm daim ntawv nyob rau hauv lub tshuab ib sab ntawm lub tshuab ziab khaub ncaws; (4) txo qhov ceev ntawm lub tshuab compound; (5) kho qhov ceev ntawm cov kab ntau lawm kom haum rau lub qhov cub ntawm lub tshuab ziab khaub ncaws; (6) Hloov daim ntawv ntawm lub ntsej muag uas hnyav tshaj qhov yuav tsum tau muaj dej noo.

2. Custom Paper Jewelry Boxes yog fake bonded

Lub npe hu ua cardboard pseudo adhesion yog hais txog cov duab los qhia tom qab lub tshuab ntawv, ntawv thiab corrugated ntawv tuaj yeem raug tshem tawm ntawm qhov tshwm sim.

Cov laj thawj tseem ceeb yog: (1) cov nplaum viscosity tsis txaus lossis tau deteriorated; (2) corrugated tshuab lossis composite locomotive ceev ceev heev; (3) lub siab ntawm lub tshuab corrugated siab cov menyuam tsis sib xws lossis cov menyuam corrugated tau hnav; (4) qhov sib txawv ntawm cov roj hmab cov menyuam ntawm lub tshuab gluing yog loj heev; (5) cov dej noo ntawm daim ntawv yog siab dhau. Kev daws: (1) txhim kho thiab ruaj khov ntawm cov nplaum zoo. Cov ntaub ntawv ntsig txog qhia tias qhov viscosity ntawm cov nplaum feem ntau yog 60S thiab 90S thaum lub caij ntuj no; Thaum lub caij ntuj sov, nws feem ntau yog 90S - 120S. Lub thawv xya-txheej feem ntau yog 305 qeeb dua li peb-txheej thawv viscosity; (2) xyuas kom meej tias lub zog siab ntawm 1.0MPa - 1.2MPa, qhov kub ntawm cov menyuam lub cev thiab lub tshuab ziab khaub ncaws yog li 160 degree; (3) domestic corrugated yob nyob rau hauv cov zis ntawm 3 lab ntev meters mus rau 3.5 lab ntev meters, yuav tsum tau hloov nyob rau hauv lub sij hawm.

Peb, washboard phenomenon

Lub npe hu ua washboard phenomenon yog hais txog cov corrugated cardboard tsim concave phenomenon raws lub ncov corrugated thiab sab nraum qab ntawm corrugated ncov ntawm daim ntawv nto. Cov duab zoo li lub tsev ntxhua khaub ncaws, yog li nws yog hu ua washboard phenomenon.

Lub hauv paus ua rau corrugated board washboard phenomenon yuav tsum tsuas yog muab los ntawm cov kua nplaum uas tsis tsim nyog, tshwm sim los ntawm ntau cov kua nplaum sib sau ua ke ntawm ob sab ntawm corrugated ncov. Qhov teeb meem no rau qhov ntau npaum li cas tsawg lub thawv board ntawv raug mob yog qhov tshwj xeeb.

Cov txheej txheem tshwj xeeb los tswj qhov tshwm sim ntawm board washboard yog raws li hauv qab no: kho kom muaj nuj nqis ntawm daim ntawv saum npoo, siv lub thawv ntawv nrog ntau dua yog qhov ncaj qha thiab zoo tshaj plaws los tshem tawm thiab txo cov duab ntawm lub tshuab ntxhua khaub ncaws (tab sis nws yuav nce tus nqi. ); Kev siv cov nplaum nplaum zoo tuaj yeem txo tus nqi ntawm corrugated ncov sizing; Tswj cov cua kub cua ntawm lub ntsej muag daim ntawv ntawm lub tshuab ua ntej, vim hais tias lub thawv board ntawv yog qhuav dhau los nqus cov kua nplaum ntau, yooj yim los tsim qhov tshwm sim ntawm lub tshuab ntxhua khaub ncaws; Kho qhov sib npaug ntawm qhov sib npaug ntawm cov menyuam thiab cov ntawv qhia cov menyuam ntawm lub tshuab ua kua nplaum sib xyaw thiab qhov sib txawv ntawm lawv, thiab nruj me ntsis coj cov menyuam (xovxwm cov menyuam) qib siab los tiv thaiv qhov tawg ntawm cov kua nplaum nce.

Iv. Dej cov ntsiab lus tswj ntawm Custom Paper Jewelry Boxes

Nyob rau hauv tus txheej txheem ntawm zus tau tej cov corrugated cardboard, kev tswj cov dej ntsiab lus ntawm cardboard yog ib qho tseem ceeb heev. Thaum cov dej cov ntsiab lus siab dhau lawm, cov ntawv ua tiav yuav zoo li mos, tsis tawv, thiab yooj yim kom tawg tom qab ntim. Thaum cov dej noo tsawg, cov ntawv ua tiav yog tawv, nkig thiab yooj yim tawg tom qab ntim. Kev tswj cov dej noo ntawm cov duab los qhia yog ib qho teeb meem nyuaj, uas yog txiav txim siab los ntawm ob yam hauv qab no:

Cov dej noo ntawm cov ntawv nyoos yuav tsum tau tswj nruj me ntsis. Raws li tus qauv tam sim no, cov dej noo ntawm cov ntawv nyoos yuav tsum yog (8 ± 2) feem pua. Thiab kev cia ntawm cov ntawv hauv paus yog qhov zoo tshaj plaws los teeb tsa lub tsev khaws khoom cais, qhov ntsuas kub feem ntau nyob rau hauv (18 ± 3) degree, av noo feem ntau nyob rau hauv (35 ± 5) feem pua. Tsis txhob muab tso rau hauv qhov chaw qhib, txwv tsis pub yooj yim ua rau muaj kev hloov pauv ntawm noo noo thiab ob qhov kawg tsis zoo li qhov nruab nrab.

Kub yog ib qho ntawm cov yam ntxwv cuam tshuam rau qhov zoo ntawm corrugated board. Nws tuaj yeem tsis tsuas yog kho cov dej noo ntawm cov ntawv hauv paus, tab sis kuj ua rau lub hauv paus ntawv sov so, uas yog ib qho tseem ceeb rau kev kho ntawm paste. Yog li ntawd, cov kab ntau lawm yog nruab nrog ntau lub tshuab ua ntej thiab lub tshuab ziab khaub ncaws, siv los kho cov dej noo ntawm cov ntawv hauv paus thiab daim ntawv ib sab, thiab ua rau cov tshuaj txhuam kom ruaj khov thiab thaum kawg ua tiav lub hom phiaj ntawm adhesion.

Txhawm rau kom tswj tau cov dej noo ntawm cov ntawv tiav corrugated, peb yuav tsum ua tib zoo saib xyuas cov teeb meem hauv qab no:

Yog hais tias cov dej ntsiab lus ntawm cov ntawv ntawv siab dhau lawm thiab qhov kub ntawm lub preheating yob tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, lub boiler chav siab yuav tsum tau nce ntxiv kom cov chav nkag mus txog saturated chav. Raws li ib txwm muaj, lub zog siab yuav tsum khaws cia ntawm 1.1Mpa ± 0.2Mpa.

Yog tias cov ntsiab lus noo noo tsawg, nws yuav tsum tau kho cov ntawv qhia cov menyuam kom txo qhov preheating cheeb tsam, thiab ua kom tag nrho siv lub tshuab ib leeg-ib tog tshuaj tsuag cov cuab yeej (wetting roller) los tsuag cov ntawv hauv paus thiab nce cov dej noo ntawm lub hauv paus. ntawv kom nws ua tau raws li tus qauv yuav tsum tau ua.

Lub tshuab ziab khaub ncaws tiaj tus hauv kev ua haujlwm, tsawg dua qhov chaw kawg, tsis tuaj yeem nres. Lub tshuab ib leeg yuav tsum nrawm ua ntej hloov cov ntawv hauv paus thiab sib sau ntau daim ntawv ntawm tus choj; Lub tshuab sib xyaw yuav tsum tau qeeb qeeb tom qab tau txais lub teeb liab, thiab tom qab ntawd ua kom nrawm dua tom qab lub tshuab ib leeg ua tiav. Yog tias cov khoom siv yuav tsum tau nres, xws li tsis ua haujlwm, daim pam conveyor yuav tsum tau nqa los tiv thaiv kom tsis txhob ya raws ntau dhau ntawm daim duab los qhia ntawm lub tshuab ziab khaub ncaws.

Rau ib lub tshuab, kho qhov sib txawv ntawm cov roj hmab cov menyuam thiab cov menyuam roj hmab. Feem ntau, qhov sib txawv ntawm cov menyuam roj hmab thiab cov menyuam roj hmab yog {{0}}.2mm-0.25mm, thiab qhov sib txawv ntawm cov menyuam roj hmab thiab lub ntsiab corrugated roller nyob rau hauv lub xeev ntawm tshav kub. tshuab yuav tsum yog 0.02 hli loj dua cov thickness ntawm corrugated ntawv siv. Rau lub tshuab ob sab, qhov sib txawv ntawm cov menyuam roj hmab thiab cov roj hmab cov menyuam kuj yog 0.2 hli - 0.25mm, qhov sib txawv ntawm cov xovxwm cov menyuam thiab cov menyuam roj hmab yuav tsum yog 0.05mm - 0.1mm me dua qhov siab ntawm ib sab corrugated cardboard los ntawm, thiab qhov sib txawv ntawm ob qhov kawg ntawm cov menyuam yuav tsum zoo ib yam, tuaj yeem ntsuas nrog lub siab.
