Peb lub neej puv nrog ntau yam ntaub ntawv luam tawm, khaub ncaws, ntawv xov xwm, thiab txhua yam ntim khoom noj. Ua cov lag luam wholesale ntim khoom noj thiab cov neeg siv khoom, peb txhawj xeeb tshaj plaws txog hom kua mem twg zoo rau ib puag ncig thiab haum rau kev lag luam ntim khoom noj. Hauv tsab xov xwm no, peb yuav qhia koj txog cov kua mem uas zoo rau ib puag ncig uas haum rau kev luam ntawv ntim khoom noj: kua mem dej.
Cov Ntsiab Lus
Lub Tswv Yim ntawm Cov Kua Xim Uas Siv Dej
Muaj ib txoj kev tshawb fawb siv los tsim cov kua mem uas hu ua dej no, uas feem ntau siv dej ua cov kuab tshuaj. Cov kua mem uas siv dej thiab lwm cov kua mem luam ntawv tsis muaj teeb meem rau kev noj qab haus huv ntawm tus neeg siv tshuab luam ntawv piv rau lawv cov tshuaj organic uas tsis yaj thiab lom. Cov ntawv luam ntawv kuj zoo rau ib puag ncig. Cov kua mem tsis yog tsuas yog muaj cov khoom uas tsis kub hnyiab xwb, tab sis nws kuj tshem tawm qhov kev hem thawj ntawm kev kub hnyiab thiab tawg hauv lub chaw luam ntawv, uas zoo rau kev ua haujlwm nyab xeeb. Tau kawg, cov kua mem thiab cov kua mem tam sim no muaj ntau yam kev siv: cov kua mem luam ntawv offset, cov kua mem luam ntawv flexographic, thiab cov kua mem luam ntawv gravure. Hauv Tebchaws Europe, Amelikas, Nyiv Pooj, thiab lwm lub tebchaws muaj kev lag luam, cov kua mem tau hloov cov kua mem tas li, nrog rau kev luam ntawv offset sab nraud ntawm lwm txoj kev luam ntawv ntawm cov kua mem tshwj xeeb. Piv txwv li, hauv Tebchaws Meskas, 95% ntawm cov ntawv luam ntawv flexographic thiab 80% ntawm cov ntawv luam ntawv gravure muaj cov kua mem.
Ntxiv rau kev tiv thaiv ib puag ncig, nws siv dav hauv ntiaj teb ntawm cov kua mem dej vim nws qhov kev ua tau zoo tshaj plaws: kev ruaj khov ntawm cov xim kua mem, lub teeb ci ntsa iab, lub zog xim muaj zog, lub phaj tsis xeb, kev nplaum zoo tom qab luam ntawv, kev ziab sai sai, tiv taus dej, luam ntawv plaub xim, luam ntawv xim, thiab lwm yam. Kev tsim thiab siv cov kua mem dej hauv Suav teb pib lig, tab sis kev nce qib tau nrawm, tshwj xeeb tshaj yog nyob rau xyoo tas los no, uas tau ua rau qhov nrawm ntawm kev txhim kho sai. Qhov zoo ntawm cov kua mem hauv tsev tau nce ntxiv nrog rau qhov kev thov ntawm cov kua mem. Cov kua mem, hauv kev nkag siab ib txwm muaj ntawm kev ziab qeeb, tsis ci ntsa iab, tsis tiv taus dej, luam ntawv cuav, thiab lwm yam tsis zoo, tau zoo dua heev. Cov nqi rau cov kua mem txawv teb chaws feem ntau siab heev, tab sis cov kua mem Suav tau kov yeej kev lag luam nrog nws cov qauv zoo nkauj thiab pheej yig. Cov nqi rau cov kua mem txawv teb chaws feem ntau siab heev, tab sis cov kua mem Suav tau kov yeej kev lag luam nrog nws cov qauv zoo nkauj thiab pheej yig.
Xav txog Cov Khoom thiab Cov Khoom Sib xyaw ntawm Cov Kua Dej Uas Siv Dej.
Cov kua mem uas yog dej yog ua los ntawm cov roj hmab uas yaj tau hauv dej, cov xim uas zoo heev, cov tshuaj yaj, thiab cov khoom ntxiv uas tau raug zom los ntawm kev ua cov txheej txheem sib xyaw ua ke. Cov roj hmab uas yaj tau hauv dej hauv cov kua mem feem ntau ua haujlwm ua cov khoom sib txuas, faib cov xim sib npaug zos kom cov kua mem muaj qee qhov kev txav mus los thiab lo rau cov khoom siv substrate kom cov kua mem tuaj yeem tsim ib txheej zaj duab xis sib npaug zos tom qab luam ntawv. Xim ntawm cov kua mem feem ntau yog txiav txim siab los ntawm cov xim, uas sib npaug zos hauv cov khoom sib txuas ua cov khoom me me, thiab cov xim me me tuaj yeem nqus, cuam tshuam, rov ua dua, thiab xa lub teeb, ua rau lawv pom ib xim tshwj xeeb. Feem ntau, cov xim yuav tsum muaj xim ci ntsa iab, muaj xim txaus thiab muaj zog npog, thiab muaj kev sib kis siab. Ntxiv mus, nyob ntawm seb siv li cas, lawv tuaj yeem muaj ntau yam kev tiv thaiv kev sib txhuam. Txoj haujlwm ntawm cov tshuaj yaj yog yaj cov roj hmab kom cov kua mem muaj qee qhov kev ntws, kev hloov pauv tuaj yeem tshwm sim zoo thoob plaws hauv cov txheej txheem luam ntawv, thiab qhov viscosity thiab kev ua haujlwm ziab ntawm cov kua mem tuaj yeem hloov kho. Cov tshuaj yaj hauv cov kua mem uas yog dej feem ntau yog dej nrog me ntsis ethanol.
Cov kua xim uas siv dej feem ntau siv cov khoom ntxiv xws li ua Defoamer, PH Value Stabilizer, Slow Drying Agent, thiab lwm yam.
(1) tshuaj ua npuas ncaujLub luag haujlwm ntawm tus defoamer yog los tiv thaiv thiab tshem tawm cov pa npuas. Feem ntau hais lus, thaum lub viscosity ntawm cov kua dej-raws li siab dhau, tus nqi PH qis dhau, lossis lub tshuab luam ntawv khiav ceev heev, nws yooj yim los tsim cov npuas. Yog tias tus lej ntawm cov npuas tsim tawm ntau heev, yuav muaj qhov xau ntawm cov xim dawb, tsis sib xws, uas yuav cuam tshuam rau qhov zoo ntawm cov khoom luam tawm.
(2) ib qho tshuaj qhuav qeeb.Ib yam khoom siv uas ua kom qhuav qeeb tuaj yeem tiv thaiv thiab qeeb qhov kev ziab ntawm cov kua mem dej kom tiv thaiv cov kua mem hauv lub phaj luam ntawv lossis cov menyuam anilox kom tsis txhob qhuav thiab txo qhov tshwm sim ntawm kev thaiv thiab nplaum cov ntawv luam ntawv tsis zoo. Tswj qhov ntau ntawm cov tshuaj ziab qeeb; feem ntau, tag nrho cov kua mem yuav tsum nyob nruab nrab ntawm 1% thiab 2%. Yog tias koj ntxiv ntau dhau, cov kua mem yuav tsis qhuav tag, thiab cov ntawv luam tawm yuav nplaum, qias neeg, lossis tsim cov ntxhiab tsw phem.
(3) PH tus nqi stabilizer:Tus nqi PH stabilizer feem ntau yog siv los tswj thiab tswj tus nqi PH ntawm cov kua dej kom nws ruaj khov nyob rau hauv qhov ntau ntawm 8.0-9.5. Tib lub sijhawm, nws kuj tseem tuaj yeem tswj qhov viscosity ntawm cov kua dej thiab cov kua dilution. Feem ntau hais lus, yuav tsum ntxiv tus nqi PH stabilizer kom tsim nyog txhua lub sijhawm hauv cov txheej txheem luam ntawv kom khaws cov kua dej kom zoo.
Kev phooj ywg ib puag ncig ntawm cov kua dej
Cov kua mem dej ua tau raws li qhov yuav tsum tau ua ntawm kev tiv thaiv ib puag ncig, cov khoom no tsis muaj tshuaj lom, tsis xeb, tsis ua rau khaus, tsis kub hnyiab, tsis tawg, muaj kev ruaj ntseg zoo, yooj yim thauj mus los, muaj cov concentration siab, cov tshuaj tsawg, viscosity tsawg, yooj yim hloov pauv rau kev luam ntawv, kev ua haujlwm ruaj khov, kev nplaum zoo, qhuav sai, dej, alkali, thiab kev ua haujlwm tiv taus kev sib txhuam zoo heev; kev luam ntawv cov qauv nyuaj kuj tseem tuaj yeem ua tiav cov qib nplua nuj, xim ci thiab ci ntsa iab, thiab lwm yam zoo. Qhov txiaj ntsig tseem ceeb ntawm kev siv cov kua mem dej yog tias nws txo cov organic volatiles (voc) tso tawm rau hauv huab cua, uas pab txhim kho cov xwm txheej luam ntawv, zam kev ua qias tuaj rau huab cua, thiab txo qis qhov kev pheej hmoo ntawm hluav taws. Txhawm rau txhim kho qhov zoo ntawm ib puag ncig, nws tuaj yeem tshem tawm qee yam khoom phom sij uas cov kua mem ua los ntawm cov kuab tshuaj muaj rau tib neeg kev noj qab haus huv, nrog rau kev ua qias tuaj uas los nrog kev ntim khoom. Nws ua haujlwm tshwj xeeb zoo rau kev luam ntawv thiab ntim khoom uas yuav tsum tau ua kom huv, xws li zaub mov thiab tshuaj.
Ua ib lub khob ntawv lag luam wholesale, GFP yeej ib txwm cog lus tias yuav siv cov khoom siv uas tsis ua rau ib puag ncig puas tsuaj, thiab lav ris rau ib puag ncig thiab kev noj qab haus huv ntawm cov neeg siv khoom. Peb cov khob ntawv yog luam tawm siv cov kua dej, thiab cov txheej txheem luam ntawv yog ua ua ntej cov khob raug laminated, yog li thaum lawv siv, cov kua los ntawm sab nraud yuav tsis txhuam rau sab hauv phab ntsa ntawm lub khob, ua kom muaj kev noj qab haus huv ntawm cov neeg siv. Thov mus saib qhov txuas hauv qab no kom paub ntau ntxiv txog peb cov khob ntawv uas tsis ua rau ib puag ncig puas tsuaj thiab cov ntawv thov cuam tshuam.
