Yuav ua li cas kom cov kabmob siab thiab compressive zog ntawm corrugated ntawv xim thawv? 

Tam sim no, feem ntau cov tuam txhab ntim khoom hauv kuv lub teb chaws siv ob txheej txheem los tsim cov thawv xim: (1) ua ntej luam cov xim ntawm daim ntawv, ces npog cov zaj duab xis los yog glazing, thiab ces manually mount cov kua nplaum los yog mechanically txiav laminate lub corrugated molding; (2) Cov duab xim thiab cov ntawv luam tawm ntawm cov yeeb yaj kiab yas, tom qab ntawd npog rau ntawm daim duab los qhia, thiab tom qab ntawd muab tshuaj txhuam thiab tsim.valentine's chocolate box

Txawm tias cov txheej txheem twg yog siv los tsim cov xim thawv xim, nws cov kabmob siab thiab lub zog compressive yog qis dua li cov khoom siv dej zoo tib yam (tsim los ntawm cov duab los qhia), thiab nws nyuaj rau lav qhov zoo thaum cov neeg siv khoom ceev. xav tau los yog hnub los nag. Cov neeg tsim khoom nyuaj siab heev, yog li yuav daws nws li cas?ncuav mog qab zib chocolate box

Txhua leej txhua tus paub tias cov thawv uas tsim los ntawm cov duab los qhia kab yog tsim los ntawm kev siv cov kua nplaum, cua sov rau kev sib txuas tam sim, thiab ziab; thaum lub laminated xim lub thawv xim lub thawv ntawv yog tsis rhuab thiab qhuav, thiab cov dej noo hauv cov kua nplaum nkag mus rau hauv daim ntawv. Ua ke nrog qhov thaiv ntawm cov kua roj vanish ntawm cov xim xim thiab cov yeeb yaj kiab yas, cov dej noo hauv lub thawv tsis tuaj yeem dissipated rau lub sijhawm ntev, thiab nws yuav soften thiab txo nws lub zog. Yog li ntawd, peb nrhiav kev daws teeb meem los ntawm cov hauv qab no:chocolate box rau khoom plig

⒈ daim ntawv sib sau ua ke khoom kim heev chocolate thawv

Qee lub lag luam muaj kev nkag siab tsis zoo: qhov hnyav ntawm daim ntawv sab hauv, ntau qhov kev coj tus kheej thiab lub zog ntawm lub thawv yuav nce ntxiv, tab sis qhov no tsis yog li ntawd. Txhawm rau txhim kho cov kabmob siab thiab lub zog compressive ntawm lub thawv xim xim lub thawv, lub siab muaj peev xwm ntawm cov ntawv tseem ceeb yuav tsum tau txhim kho. Ntev npaum li daim ntawv saum npoo tsis pom cov kab corrugated tom qab tau nplaum, cov ntawv qis yuav tsum tau siv ntau li ntau tau; cov ntawv tseem ceeb thiab cov ntawv pobzeb yog qhov zoo tshaj plaws siv. Straw pulp lossis ntoo pulp ntawv nrog lub zog zoo thiab lub nplhaib siab compressive zog. Tsis txhob siv lub zog nruab nrab lossis lub zog dav dav corrugated ntawv, vim nws feem ntau yog sib xyaw ntawm cov tawv nqaij nyoos thiab cov khoom siv rov ua dua tshiab, uas muaj cov dej nrawm nrawm, lub nplhaib qis compressive zog, thiab zoo toughness tab sis tsis tshua muaj zog. Raws li kev ntsuam xyuas, qhov nqus dej ntawm cov ntawv nruab nrab lub zog corrugated yog 15% -30% siab dua li cov ntawv pulped ntsuas los ntawm txoj kev Kebo; qhov hnyav ntawm cov ntaub ntawv hauv ob sab phlu tuaj yeem nce qhov tsim nyog. Kev xyaum tau ua pov thawj tias txo cov grammage ntawm cov ntawv sab hauv thiab ua kom cov grammage ntawm corrugated ntawv thiab cov ntawv tseem ceeb muaj kev sib tw ntau dua ntawm qhov zoo thiab tus nqi.khoom plig lub thawv ntawm chocolates

⒉ Cov kua nplaum zoochocolates khoom plig thawv

Feem ntau ntawm cov thawv ntim khoom tam sim no siv cov khoom siv hauv tsev lossis yuav cov pob kws ua kua nplaum. Cov kua nplaum zoo pob kws tsis yog tsuas yog muaj kev sib txuas zoo, tab sis kuj tuaj yeem txhim kho cov kabmob siab thiab nruj ntawm daim duab los qhia, thiab lub thawv lub cev tsis yooj yim rau deform. Qhov zoo ntawm pob kws hmoov txhuv nplej siab yog ze rau cov txheej txheem tsim khoom, ib puag ncig, zoo ntawm cov khoom siv raw thiab cov khoom sib xyaw, thiab lub sijhawm sib xyaw. Cov kev cai zoo ntawm pob kws, fineness 98-100 mesh, cov ntsiab lus tshauv tsis pub tshaj 0.1%; dej ntsiab lus 14.0%; acidity 20 CC / 100 g; sulfur dioxide 0.004%; ib txwm tsw; dawb los yog yellowish me ntsis nyob rau hauv cov xim.me me chocolate thawv

Yog tias qhov zoo ntawm cov hmoov txhuv nplej siab gelatinized tsis tau raws li tus qauv no, cov dej sib piv tuaj yeem raug txo kom tsim nyog nyob ntawm qhov xwm txheej. Raws li qhov kub thiab txias, qhov sib piv ntawm cov dej yuav tsum raug txo kom raws li, borax thiab caustic soda yuav tsum tau nce ntxiv raws li qhov tsim nyog, thiab tus nqi ntawm hydrogen peroxide yuav tsum tau txo. Cov kua nplaum yuav tsum tsis txhob khaws cia ntev, tshwj xeeb tshaj yog nyob rau lub caij ntuj sov, nws yog qhov zoo tshaj plaws los siv nws thaum koj ua. Ntxiv 3% -4% formaldehyde, 0.1% glycerin thiab 0.1% boric acid rau cov kua nplaum tuaj yeem ua rau kom cov dej tsis kam ntawm daim ntawv, ua kom nrawm nrawm, thiab ntxiv dag zog rau daim duab los qhia. tawv.khoom plig chocolate box

Tsis tas li ntawd, ib puag ncig tus phooj ywg tshuaj kua nplaum, uas yog, PVA nplaum, kuj tuaj yeem siv thaum laminated daim ntawv. Nws cov yam ntxwv yog tias laminated corrugated cardboard yog tiaj, ncaj, zoo sib txuas, thiab ruaj tsis muaj deformation. Txoj kev tsim khoom yog (noj 100kg ntawm cov nplaum ua piv txwv): cov khoom sib piv: polyvinyl cawv 13.7kg, polyvinyl acetate emulsion 2.74kg, oxalic acid 1.37kg, dej 82kg, dej ratio 1:6). Ua ntej, rhaub dej rau 90 ° C, ntxiv polyethylene glycol thiab do sib npaug, txuas ntxiv kom sov kom txog thaum cov dej npau npau, ua kom sov li 3 teev, tom qab ntawd ntxiv oxalic acid thiab do, thaum kawg ntxiv polyvinyl acetate emulsion thiab do sib npaug.

⒊ Cov kua nplaum

Txawm hais tias nws yog phau ntawv lossis tsis siv neeg kho tshuab mounting ntawm cov xim xim, cov kua nplaum siv yuav tsum tsis txhob loj dhau. Hauv kev tsim khoom tiag tiag, qee tus neeg ua haujlwm tsim cov kua nplaum ntau ntxiv txhawm rau kom tsis txhob degumming, uas tsis pom zoo thiab yuav tsum tau tswj nruj me ntsis. Cov kua nplaum yuav tsum yog 80-110g / m2. Txawm li cas los xij, nyob ntawm qhov loj ntawm corrugated corrugated, nws raug nquahu kom tuav cov kua nplaum thiab sib npaug ntawm cov corrugated peaks. Tsuav yog tsis muaj degumming, qhov tsawg ntawm cov kua nplaum, qhov zoo dua.

Qhov zoo ntawm ib sab corrugated cardboard yog txiav txim siab los ntawm qhov zoo ntawm cov ntawv hauv paus, hom corrugation, kev ua haujlwm kub ntawm lub tshuab corrugating, qhov zoo ntawm cov nplaum, kev khiav ceev ntawm lub tshuab, thiab cov txheej txheem ntawm cov txheej txheem. tus neeg ua haujlwm.
