Dab tsi yog Kev faib tawm thiab cov yam ntxwv ntawm Cov Khoom Siv Tes Ua Daim Ntawv Pov Thawj

Dab tsi yog kev faib tawm thiab cov yam ntxwv ntawm Handmade Paper Gift Box

Nyob rau hauv cov txheej txheem ntawm luam ntawv, lub compression deformation ntawm ob sab yog mas manifested raws li rhiab elastic deformation thiab yas deformation. Lub rhiab elastic deformation plays lub luag haujlwm tseem ceeb hauv kev luam ntawv, feem ntau vim tias cov khoom siv elastic ntawm cov khoom ntim ua raws li Hooke txoj cai, uas yog, qhov rhiab elasticity ntawm hauv ob sab phlu ncaj qha cuam tshuam rau elastic modulus E ntawm cov ntaub ntawv hauv ob sab phlu. Yog li, theoretically, cov elastic modulus E ntawm cov ntaub ntawv hauv ob sab phlu tuaj yeem siv los faib cov ntaub ntawv hauv ob sab phlu.

Txawm li cas los xij, tsis tsuas yog muaj ntau yam ntaub ntawv hauv ob sab phlu siv hauv cov txheej txheem luam ntawv, tab sis kuj muaj ntau hom ntawm tib hom ntaub ntawv, thiab txawm tias tib hom ntaub ntawv sib txawv. Dab tsi tshwj xeeb tshaj yog tias cov ntaub ntawv hauv ob sab phlu siv hauv kev luam ntawv feem ntau siv ua ke, yog li nws yog qhov nyuaj rau kev txiav txim siab elastic modulus ntawm cov ntaub ntawv hauv ob sab hauv luam ntawv, uas tsuas yog txiav txim siab los ntawm E. Hauv kev tsim cov xovxwm luam ntawv thiab luam ntawv. txheej txheem, cov ntaub ntawv hauv ob sab phlu yog feem ntau cais raws li cov khoom muag thiab tawv, tab sis tsis muaj kev txwv nruj ntawm cov khoom muag thiab tawv. Nws yog feem ntau ntseeg tias nyob rau hauv qhov kev txiav txim ntawm tib lub zog sab nraud, cov khoom siv hauv ob sab phlu nrog cov strain loj muaj me me elastic modulus, uas yog hu ua "mos"; thaum cov khoom siv hauv ob sab phlu nrog cov kab me me muaj qhov loj elastic modulus, uas yog hu ua "nyuaj". Yog li, cov ntaub ntawv hauv ob sab phlu tuaj yeem muab faib ua peb pawg raws li kev faib khoom muag thiab tawv:

(1) Rigid qhwv

Feem ntau muaj ib daim pam roj hmab thiab ib los yog ob daim ntawv padded ntawv (los yog yas zaj duab xis), nws thickness yog me me. Cov ntaub ntawv no yog ib qho nyuaj, lub elastic modulus ntawm lub hauv ob sab phlu yog loj, thiab ib tug me me ntawm deformation yuav ua tau ib tug loj printing siab. Thaum siv cov ntaub ntawv zoo li no, cov hauv ob sab phlu compression yuav tsum tswj tsis pub dhau {{0}}.2mm, nyiam dua nyob ib ncig ntawm 0.1mm, yog li cov ntawv luam tawm offset yuav tsum tau txo txoj kab uas hla ntawm 2 hli.

(2) Mos wrapping

Feem ntau, nws yog tsim los ntawm tuab ntaub hauv qab daim pam thiab ntau daim ntaub so ntswg, uas yog thicker. Cov ntaub mos muag tsuas yog qhov sib txawv ntawm cov tawv tawv. Nws cov elastic modulus yog me me, thiab tus nqi ntawm cov ntaub ntawv compression yuav tsum tau los tsim tib lub tshuab luam ntawv siab kuj loj. Feem ntau, qhov compression npaum li cas yog tswj nyob rau hauv {{0}}.2 ~ 0.2mm, yog li ntawd yuav tsum tau txo txoj kab uas hla ntawm offset printing xovxwm yuav tsum siab tshaj 4 hli.

(3) Cov kab hauv nruab nrab

Feem ntau, daim pam roj hmab (1.85mm) yog padded nrog tuab tuab thiab tom qab ntawd ib lub thickness ntawm daim ntawv, nws thickness yog loj dua li lub hnab ntawv nruj, lub elastic modulus nyob rau hauv qhov chaw, yog li qhov kev ua tau zoo thiab deformation kuj nyob rau hauv qhov chaw. , yog li qhov xav tau offset luam ntawv xovxwm txoj kab uas hla yuav txo qis hauv qhov ntau ntawm 3.0~ 3.5mm.
