Yuav ua li cas txiav txim qhov zoo Performance index ntawm cov nplaum los txhim kho lub zog sib txuas ntawm corrugated cardboard valentines day box chocolates

Lub zog nplaum ntawm corrugated cardboard feem ntau yog nyob ntawm qhov zoo ntawm cov nplaum thiab qhov zoo ntawm corrugated cardboard ntau lawm kab.Valentine hnub lub thawv ntawm chocolates

Adhesive zoo valonia chocolate box

Qhov zoo ntawm cov nplaum feem ntau yog nyob ntawm qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem tsim cov nplaum thiab qhov zoo ntawm cov khoom siv raw. Cov khoom siv tseem ceeb siv hauv cov nplaum yog cov hmoov txhuv nplej siab, thiab pob kws pob kws tshaj li qib kev lag luam feem ntau yog siv. Yog tias siv cov hmoov txhuv nplej siab qis, vim nws qhov kev ua haujlwm tsis zoo thiab cov khoom tsis zoo xws li cov protein thiab cov rog, nws yuav haus cov dej qab zib ntau dua, ua rau cov nplaum tsis ruaj khov, thiab cov ntawv cog lus corrugated yog ib qho yooj yim kom nqus dej noo, thiab cov nplaum nplaum. Nws yog ib qho yooj yim los tsim cov gel nrog cov hmoov txhuv nplej siab loj dua thiab cov impurities raws li cov tub ntxhais, uas ua rau cov kua dej tsis zoo. Walmart boxed chocolates

Cov ntsiab lus ntawm cov khoom, thawj tack, viscosity, pasting kub, thiab lwm yam yog cov cim tseem ceeb los ntsuas qhov zoo ntawm cov nplaum: 36 daim godiva chocolate box

1. Cov ntsiab lus ruaj khov amazon chocolate khoom plig box

Cov ntsiab lus ntawm cov nplaum yuav tsum tau txiav txim siab raws li qhov tseeb ntawm cov khoom siv, kev khiav ceev thiab qhov tseeb ntawm cov ntawv hauv paus. Thaum qhov ceev ntawm high-speed corrugated board ntau lawm kab nce mus txog 200 m / min los yog ntau tshaj, cov ntsiab lus ntawm cov nplaum yuav tsum siab. Dej thiab hmoov txhuv nplej siab Qhov sib piv feem ntau yog nruab nrab ntawm 2.5: 1-3: 1. Qhov siab dua cov ntsiab lus ntawm cov nplaum, qhov dej noo tsawg yuav yog. Ib qho me me ntawm cov kua nplaum tuaj yeem ua kom cov adhesion ntawm corrugated cardboard; thiab kev hloov ntawm noo noo nyob rau hauv cov txheej txheem ntawm corrugated cardboard ua yog me me, uas yuav txo tau lub warping ntawm corrugated cardboard. Yog tias qhov tseeb ntawm lub tuam txhab cov khoom siv qis, qhov ceev ntawm lub tsheb yog qeeb, thiab cov ntawv hauv paus yooj yim pom los ntawm, cov ntsiab lus ntawm cov nplaum yuav tsum qis dua, txwv tsis pub nws yuav ua rau muaj teeb meem zoo xws li degumming ntawm corrugated cardboard. , crystallization ntawm paste kab, thiab tawg ntawm kab. qhov zoo tshaj plaws lub thawv chocolates

2. pib tack zoo tshaj plaws chocolate box rau khoom plig

Initial tack yog tus yuam sij kom ntseeg tau qhov adhesion ntawm corrugated cardboard thiab ua kom lub tshuab ceev. Nyob rau hauv kev tsim cov corrugated cardboard, ua rau lub preheating cheeb tsam ntawm lub hauv paus ntawv, los yog ntxiv ib tug crosslinking tus neeg sawv cev thaum ua cov nplaum, ntxiv borax rau lub ntsiab lub cev thiab cov cab kuj tank feem, thiab nce cov khoom ntawm cov nplaum yuav ua rau cov nplaum. coated Tom qab lub sijhawm luv luv, nws pib tsim cov nplaum nplaum, thiab nws cov nplaum nplaum tuaj yeem rhuav tshem cov ntawv fibers. zoo tshaj plaws chocolate box rau valentines

3. viscosity zoo tshaj plaws khoom plig chocolate box

Qhov qis dua qhov viscosity ntawm cov nplaum, qhov zoo dua qhov ntws. Lub fluidity ntawm cov nplaum txiav txim siab qhov permeability ntawm cov nplaum, qhov sib xws ntawm gluing thiab cov kua nplaum, uas cuam tshuam ncaj qha rau kev ceev ntawm lub tshuab, adhesion ntawm daim duab los qhia, flatness thiab lub zog ntawm daim duab los qhia. Tsis tas li ntawd, nws tsis yog tias qhov ntau dua ntawm cov hmoov txhuv nplej siab hauv cov nplaum, qhov ua rau lub cev tsis zoo; cov nplaum nrog cov ntsiab lus siab tuaj yeem tswj tau qhov viscosity tsawg heev los ntawm kev kho cov txheej txheem kev npaj. Nyob rau hauv ib txwm muaj xwm txheej, viscosity ntawm cov nplaum yuav txo qis txhua zaus nws dhau los ntawm cov twj tso kua mis thaum lub sijhawm ncig. Lub sijhawm no, nws yuav tsum tau tov nrog cov nplaum ua tshiab.

4. gelatinization kub

Qhov kub ntawm gelatinization yog hais txog qhov pib kub uas yuav tsum tau tig cov hmoov txhuv nplej siab rau hauv ib qho muab tshuaj txhuam. Lub gelatinization kub ntawm lub binder yog ib qho tseem ceeb ntawm kev tswj kev kub ceev ntau lawm. Txhawm rau daws qhov teeb meem ntawm gelatinization qhov kub thiab txias ntawm daim ntawv khi, ntxiv rau kev kho cov dej qab zib caustic Ntxiv rau qhov ntau npaum thiab cua sov txoj kev, cov nyhuv tib yam kuj tuaj yeem ua tiav los ntawm kev ntxiv qee cov tshuaj ntxiv kom tsim nyog. Qhov kub ntawm gelatinization yuav tsum tsis txhob qis dhau, txwv tsis pub nws yuav ua rau gelatinization ntawm cov nplaum thaum lub sij hawm ncig thiab cuam tshuam rau cov kua nplaum ntawm cov nplaum. Lub gelatinization kub ntawm cov nplaum yuav tsum tau kho raws li lub caij nyoog hloov. Nyob rau lub caij ntuj no, qhov kub ntawm gelatinization tuaj yeem txo qis rau 55-60°C, thiab nyob rau lub caij ntuj sov, qhov kub ntawm gelatinization tuaj yeem hloov mus rau 61°C-66°C.

Sizing zoo ntawm corrugated cardboard ntau lawm kab

Hauv Tebchaws Europe thiab Tebchaws Meskas, qhov tseem ceeb tshaj plaws ntawm kev tshuaj xyuas qhov zoo ntawm cov thawv corrugated yog kev tshuaj xyuas qhov dav ntawm cov kua nplaum kab ntawm corrugated board. Tus qauv sizing yog tias txoj hauj lwm yog qhov tseeb, cov nplaum nplaum yog siv sib npaug thiab du ntawm tag nrho cov raj nplaim, cov kab nplaum tau qhia meej meej, thiab tsis muaj qhov projection ntawm cov nplaum los ntawm corrugation, thiab tsis muaj cov nplaum nplaum nplaum.

Kev loj hlob tsis zoo yog feem ntau cuam tshuam nrog cov khoom siv raws li txoj cai ntawm corrugated board ntau lawm kab, qhov zoo ntawm cov nplaum, thiab qhov zoo ntawm cov ntawv hauv paus.

Cov teeb meem tsis zoo tshwm sim los ntawm qhov tsis zoo ntawm qhov loj me feem ntau tshwm sim hauv cov hauv qab no:

1. Dej kua nplaum tshwm sim

Muaj cov av nyob rau saum cov menyuam yaus, xws li cov ntawv khib nyiab, cov hmoov txhuv nplej siab thiab lwm yam khoom txawv teb chaws, lossis muaj cov khoom txawv teb chaws cuam tshuam cov hlwb ntawm cov menyuam yaus, kom cov menyuam sab saum toj tsis tuaj yeem ua kom zoo, thiab tsuas yog me me xwb. Cov nplaum nplaum tuaj yeem hloov tau, thiab nws yooj yim los so Falling, thaum gluing, yuav tsis txaus gluing ntawm lub ncov corrugated, thiab yuav muaj kev sib tshuam ntawm cov gluing. Yuav muaj cov cim ntawm delamination ntawm daim ntawv saum npoo thiab cov ntawv tseem ceeb ntawm cov ntaub ntawv corrugated, thiab lub zog compressive, ntug compressive zog thiab nplaum lub zog ntawm lub thawv yuav raug txo.

Thaum qhov sib txawv ntawm cov menyuam roj hmab sab saud thiab qis corrugating cov menyuam yog dav dhau lawm, cov menyuam roj hmab sab saud tsis tuaj yeem kov cov menyuam corrugating qis, thiab tsis muaj cov nplaum txaus ntawm lub ncov corrugated.

2. Adhesive Transversal Projection Phenomenon

Yog tias cov viscosity ntawm cov nplaum yog siab dhau; Yog tias nws qis dhau los yog cov ntsiab lus ntawm borax hauv nws siab dhau lawm, nws yog ib qho yooj yim ua rau cov nplaum tua tom qab thaum cov kab ntau lawm khiav ntawm kev kub ceev, uas yuav ua rau cov duab los qhia los yog muag muag, thiab kev sib txuas. thiab sab siab ntawm lub thawv thiab compressive zog yuav txo.
