Taug kev mus rau hauv ib qho e- lag luam logistics warehouse hnub no thiab koj yuav pom cov yob ntawm cov ntaub ntawv cushioning nrawm hla cov kab ntim khoom. Ntau zuj zus, cov khoom tsis yog yas npuas qhwv ntxiv lawm - nws yog kraft daim ntawv, uas tau mechanically morphed rau hauv huab cua - puv domes, passageways los yog honeycomb hlwb. Cov cuab yeej siv los ua nws yog hu ua Styrofoam paper machine. Tab sis ob peb buyers, thaum xaj ib Bubble Paper Ua Tshuab, saib tshaj qhov loj thiab ceev cov nuj nqis los nug txog nws qhov cuam tshuam tiag tiag ntawm fiber ntau optics. Nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem thev naus laus zis xav vim tias nws txiav txim siab seb daim ntawv twg khiav huv si, lub cushion zoo li cas koj tau txais, txoj kab nrawm npaum li cas mus, thiab qhov twg cov menyuam molding xav tau tiag tiag.
Lub ntsiab lus pib: Substrate Properties thiab Tension Control
Ua ntej nias tawm ib lub dome, lubBubble Paper Ua Tshuabyuav tsum nkag mus rau daim ntawv sib npaug ntawm ib lub yob loj. Qhov dav yob yog feem ntau ntawm 300mm thiab 1500mm. Unwind nro tsis muaj qhov nthuav dav me me. Kraft daim ntawv muaj lub peev xwm qis dua ua ntej tawg -feem ntau 60 - 90 gsm, cov txheej txheem kev taw qhia tus qauv tshiab kraft yog ncab los ntawm 3-6 feem pua. Qhov no txhais tau hais tias yuav tsum muaj qhov nro ntau dhau ua ntej qhov chaw tsim yog stretched los yog torn sib nrug, es tsis txhob muaj cov fiber ntau thawb kom huv si los ntawm cov menyuam embossing.
Cov kab kev lag luam niaj hnub no siv cov hmoov sib nqus sib nqus los yog servo- tswj lub tshuab tsis muaj zog kom lub zog tag nrho cov menyuam loj lub vev xaib tsis pub dhau ± 5-10 N thaum cov menyuam loj yob tawm. Yog tias tsis muaj kev tswj hwm no, kev sib sau qhov tob ntawm yob yob pib yob kawg yog qhov sib txawv. Cov hnab tshos huab cua ua nyob rau hauv thawj ob peb metres ntawm cov menyuam tshiab yog qhov txawv ntawm qhov ua nyob ze ntawm lub hauv paus.
Lub hauv paus ntsiab lus: Mechanical Embossing ntawm Matched Forming Rollers
Txoj kev ua haujlwm yooj yim ntawm Styrofoam ntawv tshuab yog cov menyuam embossing. Qhov no tseem hu ua tuag-roller forming lossis nias-forming. Nyob rau hauv tus txheej txheem, ib daim ntawm kraft daim ntawv hla dhau qhov sib txawv tsim los ntawm ob rollers spinning nyob rau hauv opposite lus qhia. Qhov chaw ntawm cov chais no muaj cov qauv concave thiab concave.
Raws li daim ntawv nkag mus rau qhov sib txawv no, peb yam tshwm sim, txawm tias cua sov lossis chav sov:
- Ib nrab fibers nyem thiab txav mus-Txhua tus txiv neej tsa cov menyuam raug thawb mus rau hauv ib qho kev sib tw slanted poj niam cov menyuam. Daim ntawv fibers nyob rau hauv cov cheeb tsam no yog khoov mus tas li los yog txo qis (tshwj xeeb ntawm qhov chaw). Qhov no tsim ib lub dome, kem, lossis cell thiab lo rau ntawm daim ntawv qub.
- Nws hardens thaum nws stretches dome phab ntsa- fiber ntau optic network ntawm txhua lub npuas sab yog ncab.
