Cov nyhuv ntawm cov khoom ntawm cov khoom raug sau rau ntawm warping ntawm daim ntawv lo
Due to the different materials of the pasted objects, their surface energy will be different, so the effect of the same self-adhesive label after labeling will also be different. Normally, the surfaces of different materials can be compared as follows: stainless steel> glass> PET>PP>PE.
Tsis tas li ntawd, qhov saum npoo ntawm cov khoom siv tib yam kuj tseem yuav txawv vim cov txheej txheem sib txawv, xws li siliconized iav fwj, lub raj mis yas nrog qhov sib txawv ntawm qhov sib txawv, thiab lwm yam. Yog li ntawd, rau cov khoom lossis lub raj mis lub cev nrog lub zog sib txawv, nws yog ib qho tsim nyog yuav tsum siv cov nplaum sib txawv kom phim.
05
Kev cuam tshuam ntawm cov duab ntawm cov khoom ntawm warping ntawm daim ntawv lo
Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws, daim ntawv lo ntawm cov khoom siv yuav tsum yog qhov chaw tiaj tus tom qab nthuav tawm. Yog tias daim ntawv lo saum npoo ntawm cov khoom yuav tsum tau thov yog nkhaus hauv ob qho kev qhia tom qab nthuav tawm (sperical labeling nto), nws nyuaj rau ua tiav cov txiaj ntsig zoo tshaj plaws. Yog li ntawd, lub raj mis lub cev yuav tsum tau tsim kom tsis txhob muaj cov duab zoo li no ntau li ntau tau, los yog sim kom tsis txhob muaj txoj hauj lwm zoo li no thaum sau npe.
Tsis tas li ntawd, vim lub siab ntawm cov nqi tsim khoom, tshuab moulding nroj tsuag feem ntau txo qhov hnyav ntawm lub raj mis lub cev, kom lub raj mis lub cev ua thinner, ua rau lub cev loj deformation ua ntej thiab tom qab sau, thiab nws yog tsis yooj yim sua rau exert loj labeling siab, xws li thaum kub filling 30℃~ 40℃kua tom qab labeling, lub raj mis lub cev ib feem yuav raug tsa thiab deformed, thiab tom qab lub raj mis txias yuav retractable. labeling thiab warping.
06
Cov nyhuv ntawm qhov chaw ntawm cov khoom yuav tsum tau sau rau ntawm warping ntawm daim ntawv lo
Qhov roughness ntawm qhov chaw ntawm cov khoom muaj kev cuam tshuam zoo rau cov nyhuv labeling, thiab qhov rougher ntawm qhov khoom, qhov ntau yuav ua rau muaj teeb meem ntawm daim ntawv lo warping. Tsis tas li ntawd, yog tias muaj cov impurities xws li roj, cov tee dej, thiab cov plua plav ntawm qhov chaw ntawm cov khoom, nws yog qhov sib npaug ntawm cov nplaum nplaum rau cov impurities, tsis yog lo rau saum npoo ntawm cov khoom, thiab nws yooj yim rau warp daim ntawv lo.
Tsis tas li ntawd, txawm tias qhov chaw ntawm cov khoom yuav tsum tau sau npe tau raug kho nrog cov txheej txheem tshwj xeeb kuj tseem tuaj yeem cuam tshuam rau qhov kawg daim ntawv lo, xws li lub taub me me iav fwj nyob rau hauv cov txheej txheem ntawm potions, vim tias cov tshuaj tsis raug tso cai rau dai rau ntawm phab ntsa, lub raj mis yuav raug ntxuav nrog dej silicon ua ntej, yog tias muaj ntau ntawm silicon residue tom qab ntxuav, daim ntawv lo tom qab ntawv yuav muaj teeb meem.

Kev cuam tshuam ntawm ib puag ncig labeling ntawm labeling warping
Feem ntau, daim ntawv lo rau qhov ntsuas kub feem ntau suav nrog plaub yam: daim ntawv qhia qhov kub thiab txias, qhov ntsuas kub ntawm qhov ntsuas kub, thiab qhov ntsuas kub cia hauv 24 teev tom qab ntawv, raws li hauv qab no:
(1) Cov kev tsis sib haum xeeb ntawm txhua tus kheej - cov khoom siv nplaum nplaum tau cim meej nrog qhov tsawg kawg nkaus daim ntawv lo thiab siv qhov kub thiab txias, xws li qhov ntsuas kub tsawg kawg nkaus ntawm NW5539 daim ntawv lo khoom yog 10 degree, thiab kev siv kub yog -15℃~ 65℃.
(2) Thaum sau ntawv, qhov kub ntawm qhov chaw yuav tsum ua kom tau raws li qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus ntawm daim ntawv lo, tsuas yog nyob rau hauv txoj kev no tuaj yeem ua rau daim ntawv nplaum ntws ib txwm thiab ua rau lub cev tsis zoo.
(3) Qhov kub ntawm qhov khoom siv yuav tsum yog siab tshaj qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus, yog li cov nplaum nplaum nrog cov dej ntws tsis zoo yuav tsis ua kom tsis zoo lossis tsis ntws vim nws txuas rau qhov qis - qhov kub thiab txias, ua rau txo qis hauv viscosity.
(4) Lub ambient kub ntawm kev cia tom qab daim ntawv lo kuj tseem ceeb heev, thiaj li yuav tswj tau lub fluidity ntawm cov nplaum thiab hloov cov nplaum nplaum los ntawm thawj viscosity mus rau qhov kawg viscosity, nws yuav tsum tau ua kom tiav nyob rau hauv ib puag ncig tshaj qhov tsawg kawg nkaus daim ntawv lo kub.
Cov txheej txheem sau npe sib txawv kuj tuaj yeem muaj feem cuam tshuam rau cov teeb meem ntawm daim ntawv lo. Piv txwv li, ib qho dej khov nab kuab puv lub thawv yas nrog dej khov ntawm qhov ntsuas kub ntawm 10 degree, cia li sau lub hau, thiab mam li cia li sau lub hau thiab ib ncig ntawm lub thawv, thiab thaum kawg khov nws nyob rau hauv qhov kub thiab txias ntawm -15 degree, thiab tom qab ntawd hloov mus rau qhov txias txias rau 1 ~ 2 teev.
Txhawm rau daws qhov teeb meem no, lub tuam txhab tau sau lub thawv yas uas yuav tsum tau ntim cov dej khov rau hnub thib ob ua ntej, thiab tom qab ntawd nchuav, capped, thiab ceev - khov tom qab 24 teev ntawm kev sau ntawv, thiab xa mus rau qhov chaw txias txias rau kev cia, uas daws cov teeb meem ntawm daim ntawv lo warping zoo.
Rau qhov sib txawv ntawm qhov chaw thiab daim ntawv lo yuav tsum tau xaiv, cov txheej txheem sib txawv yuav tsum tau xaiv, feem ntau siv xws li lub log sponge, pulleys, labeling plates, thiab lwm yam. Tsis tas li ntawd, lub tshuab labeling yuav tsum siv cov ntawv nplaum tsim nyog rau daim ntawv lo kom paub meej tias daim ntawv lo tuaj yeem haum nrog cov khoom siv.
Thaum daim ntawv lo lub siab tsis txaus, xws li siv cov txhuam mos, daim ntawv lo uas muag muag heev, lossis qhov sib nrug ntawm lub log thiab rub lub raj mis thiab lub raj mis loj dhau lawm, daim ntawv lo yuav warp vim lub siab tsis txaus. Tsis tas li ntawd, yog tias daim ntawv lo tshuab yog kev laus, nws yuav cuam tshuam rau lub siab ntawm daim ntawv lo, uas yuav ua rau muaj teeb meem ntawm kev sib tsoo.
Labeling thiab txhawb nqa cov neeg siv khoom
Xyoo 2021, PE tus kheej- daim ntawv nplaum ntawm lub tuam txhab muaj qhov tshwm sim tsis sib haum xeeb thaum lub sijhawm sau npe, uas yuav tsum tau kho sai sai. Nws tau kawm los ntawm qhov chaw lag luam tias tom qab lub tuam txhab tau muab cov ntawv nplaum los ntawm qhov chaw cia txias, nws tau sau npe thaum tseem muaj condensation nyob rau saum npoo ntawm daim ntawv nplaum, thiab tam sim ntawd muab cov khoom tso rau hauv qhov chaw txias txias nrog qhov kub thiab txias heev tom qab daim ntawv lo, uas tsis ua rau daim ntawv lo cia kub txog li 10 degree. Yog li ntawd, peb txiav txim siab hais tias lub labeling warping phenomenon yog tshwm sim los ntawm ib puag ncig teeb meem.
Kev ua haujlwm ib txwm yog: daim ntawv lo yuav tsum tau muab khaws cia rau hauv ib puag ncig siab dua 10℃24 teev ua ntej sau npe, vim tias cov nplaum ntawm daim ntawv no tsuas yog muaj cov dej ntws zoo hauv ib puag ncig saum 10 degree, thiab cov nplaum tuaj yeem ua si ib txwm.
Raws li cov lus pom zoo, lub tuam txhab tam sim ntawd tau txhim kho thiab kho qhov chaw uas cov ntawv khaws cia kom ntseeg tau tias qhov kub ntawm cov ntawv khaws cia yog siab tshaj 10 degree. Tom qab tshaj tawm - taug qab, tsis muaj teeb meem kev sau npe tau pom nyob rau hauv cov ntawv sau los ntawm lub tuam txhab.
Txawm hais tias nws yog lub tuam txhab luam ntawv lossis tus neeg siv kawg, nws yuav tsum xaiv qhov tsim nyog tshaj rau tus kheej -cov ntaub ntawv nplaum raws li daim ntawv thov tiag tiag ntawm daim ntawv lo, thiab xyuam xim rau qhov cuam tshuam ntawm qhov kub thiab av noo ntawm daim ntawv lo. Tsuas yog los ntawm kev txiav txim siab ntau yam tuaj yeem ua rau peb txhim kho daim ntawv lo zoo ntawm cov khoom thiab ua rau lawv zoo nkauj dua.
