Yam ntxwv ntawm cov khoom noj ua kua muag yas yas ntim zaj duab xis
Cov khoom siv yees duab siv rau cov thev naus laus zis yas yog cov polyethylene (PE) coextruded zaj duab xis, uas yuav tsum ua kom tau raws li qhov yuav tsum tau ntim cov ntawv luam tawm, ua, khaws cia thiab kev thauj mus los. Los ntawm cov tsos thiab kev ua yeeb yam ntawm zaj duab xis, nws muaj peev xwm raug muab faib ua peb pawg: xim mos dawb PE film, dub thiab dawb co-extruded PE zaj duab xis, nyuaj kub kub ua noj PE zaj duab xis.
Cov xim mos-xim dawb PE yog siv los ua cov kua dej yooj yim xws li mis nyuj, kua ntses thiab kua txiv hmab txiv ntoo. Qhov co-extrusion cua tshuab zaj duab xis masterbatch yog li ntawm LDPE, LLDPE thiab cov khoom dawb huv. Kev ua yeeb yam ntawm zaj duab xis yog cov neeg txom nyem, qhov ntsuas ntawm qhov ntsuas tsis tshaj li ntawm 90 ° C, lub txee lub neej yog luv luv; feem ntau siv nyob rau hauv phau ntawv los yog qis-puv cov khoom siv. Piv txwv li, cov khoom ntim qis me me, lub txee niaj hnub mus txog peb hnub, ze ntawm kev muag khoom.
Dub thiab dawb zaj duab xis yog feem ntau peb txheej, thiab qhov siab tshaj plaws yog tsib txheej. Thaum cov yeeb yaj kiab raug cua tshuab, tus txheej txheem txuas ntxiv nruab nrab yog coextruded nrog ib tus cwj pwm tswj tuav. Cov dub masterbatch ntawm lub puab txheej ntawm lub tshav kub ua haujlwm pab cuam rau thaiv lub teeb thiab thaiv ultraviolet rays. Vim yog lub hav zoov ntawm cov txheej txheem thaiv theem, nws muaj li ntawm masterbatch xws li E-VA thiab EVAL. Lub txee lub neej ntawm tus txheem ntev dua thiab tuaj yeem tswj tau ntau dua 30 hnub. Txawm li cas los xij, muaj qee qhov peb theem ntawm cov xim dub thiab dawb ntawm kev ua lag luam, thiab nruab nrab txheej tsis yog Nws yog tsim los ntawm tus thawj tswj kev ruaj khov, yog li cov xim dub thiab dawb kuj yog nyob rau hauv thawj qeb. Ntawm peb hom kev yeeb yam, dub thiab dawb films yog cov feem ntau tsis nyiam luam tawm haujlwm. Thaum cov dub thiab dawb zaj duab xis tsim, tus nqi ntawm tus neeg kos npe thiab lub ci ntsa iab yog qhov loj tshaj plaws, yog li ua kom tau raws li qhov kev xav tau tias cov xim dub thiab dawb kuj muaj me me kev txhuam coefficient rau high-speed automatic filling tshuab, thiab ntxiv oily quav tshuaj yog tsis tshua muaj disadvantageous rau xim printing txheej txheem, thiab txo qhov txo yog zoo heev txo. Adhesion zog ntawm tus number case txheej. Rau feem ntau cov high-speed tuaj puv cav, ib lub cev kom tsis muaj menyuam nruab nrog cov roj kub hnyiab tau siv rau kev siv lub thev naus laus zis. Nyob rau hauv cov ntaub ntawv no, yuav tsum tau them nyiaj rau cov nyhuv ntawm cov kab mob sterilization ntawm cov ink number txheej vim hais tias qee tus pigments hauv tus cwj mem muaj oxidation tsis kam. Cov kev kuaj pom tau hais tias qhov oxidation ntawm hydrogen peroxide yog ib qho zoo tuaj nrog kev nce kub. Vim li no, xim luam ntawv yuav tsum to taub meej txog cov kev lag luam tom qab ua cov neeg siv khoom thaum muab cov khoom ntim.
Qhov kub siab ua kub ua noj PE film yog siv rau cov khoom siv mis nyuj xws li yoghurt thiab soy milk. Tus txheem yog sterilized tom qab txhaws, thiab ultra-kub kub sterilization txheej txheem yog saws. Qhov nyuaj co-extruded PE zaj duab xis yog tsim los ntawm HDPE masterbatch, thiab ib feem ntawm LDPE thiab colored colored masterbatch. Yog li no, cov PE zaj duab xis muaj qhov kub siab ua haujlwm zoo thiab tuaj yeem ua raws li qhov yuav tsum tau ua ntawm ultra-high temperature sterilization. Vim muaj qhov sib txawv ntawm qhov sib txawv thaum lub cev kom tsis muaj menyuam, nws yooj yim los tsim "lub hnab expansion". Yog li ntawd, nws yuav tsum tau kom cov PE zaj duab xis tsis tsuas muaj cua kub zoo zog, tab sis kuj tensile zog ntawm zaj duab xis zoo. Cov xim luam yeeb muag feem ntau yog siv "peb lub tsheb pov tseg" los yog "Cov neeg ruam ntawm ib kauj ruam" qhov kev sim.
Naj hla luam tawm rau cov xim yas ntim kua yas ntim
Cov dej ntim cov kua dej ntim xws li mis thiab haus dej feem ntau yog luam tawm ntawm qhov luam tawm. Feem ntau ntawm lawv yog tsim los ntawm polyamide los yog hloov mus rau cov ntaub ntawv txuas. Cov phev yog qhov ntxov tshaj plaws nyob rau hauv Suav teb tus gravure inks, thiab cov txheej txheem ntau lawm yog tus muaj kev paub tab thiab zoo meej. Hom khaub noom hom no yog tsim rau cov yeeb yaj kiab thiab polypropylene. Lub adhesion ntawm tus number case txheej zoo thiab lub gloss yog qhov zoo. Txawm li cas los xij, cov cwj mem polyamide muaj cov dej tsis haum, tsis tuaj yeem ua rau roj, thiab tsis tuaj yeem ua kom khov thiab lwm cov kev ua haujlwm tsis zoo. Cov cwj mem li no muaj luam tawm nyob rau lub caij ntuj sov thaum muaj kev kub ntxhov, uas ua rau ua rau lub cev thiab npliag. Thaum luam ntawv tsawg kawg thaum lub caij ntuj no, nws yuav khov.
Lub pob dej ua rau kub kub cev los yog khov rau lub sij hawm tom qab ua tiav cov txheej txheem ntawm kev sau, kev ncig thiab cia khoom. Yog li no, qhov tsis xws luag ua rau lub hnab ntim ntawm polyamide nyob rau hauv cov ntawv luam tawm tsis tau raws li cov dej ntim, thiab xim luam chaw tsim ua cov kua roj Non-polyamide ntim hauv tshuab luam ntawv yuav tsum raug siv rau ntau hom kev cov pa roj carbon monoxide - PE zaj duab xis. Tam sim no, cov kua dej ntim rau hauv khw feem ntau yog polyesters thiab hloov khoom, uas yog ib leeg-kua thiab ob-kua reactive. Ink.
Vim tias cov mis thiab dej haus yog rau tib neeg noj, ntim films, printing inks, thiab lwm yam yuav tsum tau ua raws li cov cai ntawm ntim cov ntaub ntawv kev nyiam huv thiab cov kev cai noj zaub mov. Yog li, cov thev rau hauv cov ntawv luam tawm yuav tsum tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab muaj cov kua dej tsawg dua. Tsis muaj tshuaj lom hnyav hnyav thiab lwm yam yuav tsum muaj.
Yuav kom tsis txhob muaj cov kua mis thiab dej haus, thiab ua kom raug mob rau cov neeg siv khoom noj.
Raws li cov kev cai saum toj no rau cov ntawv cim xaj, nws yog ib qho tsim nyog yuav xaiv ib tug number case uas muaj kev ua tau zoo. Kev luam ntawv siv ob hom kev xuas tshuab luam ntawv, thiab kho cov kua roj voos uas yog siv tom qab luam tawm cov cwj mem, uas yog tus nqi loj thiab cumbersome hauv tus txheej txheem. Tam sim no, qhov dav siv thiab zoo dua yog Super Lifu 313A ntu luam tawm number case thiab Super Life 314 hom luam tawm los ntawm Zhejiang Tshiab Oriental Ink Group Co., uas tsis tas yuav tsum muaj coated nrog vev hauv luam ntawv number case. Muaj ntau npaum li cas ntawm cov tshuab hardener ntxiv, thiab tom qab 24 teev ntawm kev laus, nws tuaj yeem yog ob qho dej-resistant, hydrogen peroxide-resistant thiab txhuam-resistant.
Cov phaw thib ob yog cov tshwj xeeb luam hauv qab tsim los rau cov kua mis thiab haus dej ntim films, thiab muaj zoo affinity nrog polyethylene zaj duab xis, zoo gloss ntawm number case txheej, siab ua kom ceev nrooj, tshav kub tsis haum, roj thiab ua haujlwm. Dej raws cov khoom muaj kuj zoo heev; nws yog qhov zoo rau cov dej ntim ntim zaj duab xis hauv xws li mis haus thiab dej haus. Lub neej Super Life 313A yog tus cwj mem kua-tshuaj kua roj naj npawb uas muaj peev xwm tiv thaiv npau npau 100 ° C thiab tuaj yeem tiv thaiv tau 60% los yog tsawg dua ntawm cov tshuaj hydrogen peroxide. Chaolifu 314 npo luam tawm number case yog ob-kua kua tshuaj feem ntau ntawm cov roj pleev hloov uas muaj peev xwm tuaj yeem tiv thaiv sterilisation ntawm 121 ° C / 40 feeb, thiab tuaj yeem txheem hydrogen peroxide sterilization ntawm 80 ° C thiab concentration ntawm 35%. Raws li oxidation kuj kuaj ntawm Chaolifu 314 ob hom kua tshuaj kua mem kua, daim duab luam tawm tom qab laus 24 lub sij hawm raug raus hauv hydrogen peroxide ntawm qhov kub ntawm 45 ° C mus rau 50 ° C thiab ib qho concentration ntawm 35% rau txog 15 nas this , thiab tom qab ntawd coj tawm tom qab nrhiav tau. Cov cwj mem xaj muaj kev nplua zoo thiab yeej tsis muaj xim txawv, thiab tuaj yeem ua tau raws li cov cai ntawm cov dej ntim xws li mis haus thiab dej haus.
