Nrog rau kev txhim kho kev ua neej nyob tsis tu ncua, tib neeg cov qauv nruj tsis txwv rau cov zaub mov nws tus kheej. Cov kev xav tau rau nws cov ntim khoom kuj nce. Kev ntim khoom noj tau maj mam dhau los ua ib feem ntawm cov khoom lag luam los ntawm nws qhov chaw pabcuam. Nws yog ib qho tseem ceeb los tiv thaiv cov khoom, Nws yog ib qho tseem ceeb heev los pab txhawb kev khaws cia thiab kev thauj mus los, txhawb kev muag khoom, thiab ua kom cov khoom muaj nqis.
Printing ntawm cov khoom noj hloov pauv cov khoom ntim khoom
① Cov txheej txheem luam ntawvKhoom noj khoom haus saj zawg zog ntim printingFeem ntau yog raws li gravure thiab flexographic luam ntawv, ua raws li cov tshuab luam ntawv flexographic los luam cov yas yeeb yaj kiab (flexographic tshuab luam ntawv feem ntau tsim cov kab ntau lawm nrog cov tshuab lamination qhuav), tab sis nrog kev tshaj tawm, piv nrog rau kev luam ntawv gravure thiab flexographic luam ntawv siv hauv cov khoom lag luam luam ntawv, muaj ntau qhov sib txawv. Piv txwv li: Flexible packaging printing yog luam tawm nyob rau saum npoo ntawm ib tug yob-puab substrate. Yog tias nws yog ib zaj duab xis pob tshab, cov qauv tuaj yeem pom ntawm sab nraub qaum. Qee lub sij hawm nws yuav tsum tau ntxiv ib txheej ntawm cov xim dawb los yog siv cov txheej txheem luam ntawv sab hauv.
② Lub ntsiab lus ntawm cov txheej txheem luam ntawv rov qab Rov qab luam ntawv yog hais txog txoj kev luam ntawv tshwj xeeb uas siv lub phaj luam ntawv nrog cov duab thim rov qab thiab cov ntawv xa cov number case mus rau sab hauv ntawm cov khoom luam tawm pob tshab, kom cov duab zoo thiab cov ntawv tuaj yeem tso tawm rau pem hauv ntej. ntawm cov khoom luam tawm.
③ Qhov zoo ntawm Liyin
Piv nrog rau saum npoo luam ntawv, cov ntaub ntawv luam tawm muaj qhov zoo ntawm qhov ci thiab zoo nkauj, muaj yeeb yuj / tsis fading, noo noo-pov thawj thiab hnav-resistant. Tom qab cov ntaub ntawv luam tawm yog sib xyaw ua ke, cov kua nplaum txheej yog sandwiched ntawm ob txheej ntawm zaj duab xis, uas yuav tsis kis cov khoom ntim.
Kev sib xyaw ntawm cov khoom noj hloov pauv cov khoom ntim khoom
① Cov txheej txheem ntub dej ntub dej: Txheej txheej dej-soluble nplaum rau ntawm qhov chaw ntawm cov khoom siv hauv paus (yas zaj duab xis, aluminium ntawv ci), muab nws nrog lwm cov ntaub ntawv (daim ntawv, cellophane) los ntawm lub siab rau cov menyuam, thiab tom qab ntawd qhuav hauv qhov kub. drying tunnel Ua ib daim nyias nyias. Txoj kev no yog tsim rau ntim cov zaub mov qhuav.
② Cov txheej txheem lamination qhuav: ua ntej siv cov kua nplaum raws li cov nplaum sib npaug ntawm lub substrate, thiab tom qab ntawd xa mus rau qhov kub ziab kom qhuav kom tag nrho evaporate cov kuab tshuaj, thiab tom qab ntawd mam li laminate nrog lwm txheej ntawm zaj duab xis. Piv txwv li, oriented polypropylene zaj duab xis (OPP) feem ntau yog sib xyaw nrog lwm cov ntaub ntawv siv cov txheej txheem lamination qhuav tom qab luam ntawv sab hauv. Cov qauv tsim yog: biaxially oriented polypropylene zaj duab xis (BOPP, 12 μm), aluminium foil (AIU, 9 μm) thiab unidirectional Stretched polypropylene zaj duab xis (CPP, 70 μm). Cov txheej txheem yog siv cov txheej txheem rau cov menyuam txheej txheej kom sib npaug ntawm cov kuab tshuaj raws li "cov nplaum nplaum qhuav" ntawm cov khoom siv hauv paus, thiab tom qab ntawd xa mus rau qhov kub kom qhuav kom tag nrho evaporate cov kuab tshuaj ua ntej laminating nrog lwm txheej ntawm zaj duab xis siv ib tug laminating cov menyuam.
③ Cov txheej txheem extrusion compounding extrudes cov ntaub ntawv zoo li molten polyethylene los ntawm qhov slit ntawm T pwm, nias nws los ntawm pinch roller, thiab drools nws mus rau daim ntawv los yog zaj duab xis rau polyethylene txheej, los yog muab lwm cov yeeb yaj duab los ntawm ob daim ntawv pub mis. Siv polyethylene ua cov nplaum txheej rau kev sib txuas.
④ Cov txheej txheem kub yaj: Polyethylene-acrylate copolymer, ethylene acid-ethylene copolymer, thiab paraffin wax yog rhuab thiab yaj ua ke, ces coated rau ntawm substrate, tam sim ntawd compounded nrog lwm cov ntaub ntawv sib xyaw thiab ces txias.
⑤Multi-layer extrusion compounding method
Ntau yam ntawm cov yas resins nrog cov khoom sib txawv tau dhau los ntawm ntau lub extruders thiab extruded rau hauv pwm los ua ib zaj duab xis. Cov txheej txheem no tsis tas yuav muaj cov nplaum nplaum lossis cov kuab tshuaj organic nruab nrab ntawm cov khaubncaws sab nraud povtseg, thiab cov yeeb yaj kiab tsis muaj ntxhiab tsw los yog cov kuab tshuaj lom, ua rau nws tsim nyog rau ntim khoom noj nrog lub txee ntev dua. Piv txwv li, cov qauv ntawm LLDPE / PP / LLDPE muaj qhov pom tseeb zoo thiab cov tuab feem ntau yog 50-60μm. Yog tias nws muaj lub neej txee ntev dua. Yuav tsum muaj ntau tshaj li tsib txheej ntawm high-barrier co-extruded films, thiab nruab nrab txheej yog ua los ntawm high-barrier cov ntaub ntawv PA, PET thiab EVOH.
