Cov Cuam Tshuam cuam tshuam rau Kev Ua Yeeb Yaj Kiab Curing & Txhim Kho Cov Lus Qhia

Txhawm rau ua tiav cov txiaj ntsig kho kom zoo, ntau yam xav tau xav txog, suav nrog:

1. Daim ntawv kho chav thiab xwm txheej zoo tshaj plaws: nrawm thiab cua kub los ntawm cov khoom siv cua sov thiab qhov av; hauv av thiab ob lossis ntau sab ntawm chav kho kom muaj cua sov txaus thiab zoo ib yam; qhov sib txawv me me ntawm qhov tseeb thiab teeb tsa qhov kub, thiab kev khaws cua sov thiab tso pov tseg raws li qhov kev thov; zaj duab xis yob yog yooj yim txav thiab nqa.

2. Cov khoom ua tau raws li kev thov.

3. Cov haujlwm, tus nqi corona, tiv tshav kub, thiab lwm yam ntawm lamination fims.

4. Cov nplaum: cov nplaum hnyav, cov nplaum tsis hnyav, ib lossis ob zaug tiv thaiv dej puag nplaum, kub yaj nplaum, thiab lwm yam.

Daim ntawv no feem ntau tsom mus rau cov yeeb yaj kiab lamination thiab cov nplaum.

1. Lamination Films

Lub cev, tiv tshav kub thiab tiv thaiv kev ua tau zoo ntawm PE zaj duab xis, uas tau siv dav, yuav zoo dua, thaum qhov ntom ntawm PE nce. PE zaj duab xis nrog qhov ntom ntom tab sis cov txheej txheem tsim khoom sib txawv muaj kev ua yeeb yam sib txawv.

CPE tuaj yeem ua kom txias sai, nrog qhov qis crystallinity, siab ua kom pom tseeb thiab tsis muaj kuab paug. Tab sis cov txheej txheem molecular tsis xwm yeem, ua rau nws ua tsis tau zoo, uas yog kev sib kis siab. Thiab nws zoo ib yam nrog LDPE. Yog li ntawd, kho qhov kub yuav tsum tsis txhob siab dhau thaum siv PE zaj duab xis. Thaum tshav kub tsis kam ntawm PE yog kev txhim kho, qhov kub ua kom sov tuaj yeem siab dua.

2. Cov nplaum

2.1 E ibthyl Raws Adhesive

Raws li kev ua yeeb yaj kiab ntawm cov yeeb yaj kiab lamination thiab cov nplaum, kev kho kom zoo tuaj yeem faib ua ntau qib:

1. Kub 35, sijhawm 24-48h

2. Kub 35-40, sijhawm 24-48h

3. Kub 42-45, lub sijhawm 48-72h

4. Kub 45-55, sijhawm 48-96h

5. Tshwj xeeb, kub tshaj 100, sijhawm raws li kev txhawb nqa txuj ci.

Rau cov khoom lag luam ib txwm, txiav txim siab qhov ntom ntom, tuab, tiv thaiv thaiv, ua kom sov ua haujlwm zoo ntawm cov yeeb yaj kiab nrog rau cov hnab loj, kho qhov kub yuav tsum tsis txhob siab dhau. Feem ntau, 42-45lossis qis dua yog txaus, sijhawm 48-72 teev.

Cov yeeb yaj kiab txheej sab nrauv, uas xav tau kev ua haujlwm siab thiab tiv taus cua sov zoo tsim nyog rau kev kho qhov kub, zoo li ntau dua 50. Cov yeeb yaj kiab sab hauv, zoo li PE lossis tshav kub sib khi CPP, haum rau 42-45, kho lub sijhawm yuav ntev dua.

Cov khoom lag luam rhaub lossis rov ua haujlwm, uas xav tau kev ua haujlwm siab thiab tiv taus tshav kub, yuav tsum ua raws li cov txheej txheem tua kab mob uas lub Hoobkas nplaum muab.

Lub sijhawm tua yuav tsum ua raws li qhov ua tiav cov tshuaj tiv thaiv, kev sib txhuam coefficient thiab kev ua kom sov sov.

Cov khoom tshwj xeeb yuav xav tau kom kub dua.

2.2 Solventless Adhesive

Yog hais tias kev sib khi ua tau zoo raws li qhov uas yuav tsum, rau solventless laminating khoom, uas puab films muaj tsawg ceev, lub adhesives muaj ntau free monomers, ua rau nws nyuaj rau lub tsiaj hiav txwv. Yog li, qhov ntsuas kub tsawg tau pom zoo, rau 38-40.

Yog tias qhov tshuaj tiv thaiv kab mob ua tiav raws li qhov yuav tsum tau ua, yuav tsum tau kho lub sijhawm ntev dua.

Yog tias cov cua sov ua kom sov muaj cov ntom ntom ntom ntom ntom ntom ntom ntom ntom, cov ntsuas kub yuav tsum yog 40-45. Yog tias qhov ua tiav cov tshuaj tiv thaiv thiab kev ua kom sov sov xav tau kev txhim kho, lub sijhawm kho yuav tsum ntev dua.

Kev ntsuas nruj me ntsis yog qhov yuav tsum tau ua ua ntej pawg ntau lawm, kom ntseeg tau tias qhov zoo.

Dab tsi ntxiv, av noo yuav tsum tau txiav txim siab. Tshwj xeeb tshaj yog nyob rau lub caij ntuj no qhuav, cov av noo tsim nyog tuaj yeem ua kom nrawm dua.

2.3 Dej Raws Adhesives

Thaum laminating VMCPP, tshuab lamination yuav tsum qhuav kom txaus, lossis txheej aluminized yuav raug oxidized. Thaum kho, qhov kub yuav tsum tsis txhob siab dhau lossis qis dhau. Kub siab yuav ua rau muaj kev sib txhuam coefficient.

2.4 Kub Qhuav Nplaum

Feem ntau xaiv ntuj zoo, tab sis kev ua tau zoo tom qab yaj yuav tsum pom.

3. Tswj nruj ntsuas kub

Raws li kev tshawb fawb, ntawm cov yam ntxwv ntawm cov tshuaj tiv thaiv, yuav luag tsis muaj cov tshuaj tiv thaiv qis dua 30. Tshaj 30, txhua txhua 10siab dua, cov tshuaj tiv thaiv txhim kho txog 4 zaug. Tab sis nwsqhov tsis raug txhawm rau txhim kho qhov kub kom ua kom nrawm dua cov tshuaj tiv thaiv qhov muag tsis pom, ntau yam yuav tsum tau pomcov tshuaj tiv thaiv tiag tiag, kev sib txhuam coefficient thiab lub zog ua kom sov sov.

Txhawm rau ua tiav qhov txiaj ntsig zoo tshaj plaws, ntsuas kub yuav tsum tau muab faib ua ntau yam sib txawv, raws li cov yeeb yaj kiab lamination thiab cov qauv.

Txog tam sim no, cov teeb meem tshwm sim muaj raws li hauv qab no:

Ib qho, kho qhov kub tau qis dhau, ua rau cov tshuaj tiv thaiv qis, thiab cov khoom muaj teeb meem tom qab kub kaw lossis rhaub.

Qhov thib ob, kho qhov kub siab dhau thiab ua kom sov zaj duab xis muaj qhov ntom ntom. Cov khoom muaj qhov ua tau zoo kub tsis zoo, kev sib txhuam coefficient siab thiab cuam tshuam los tiv thaiv tsis zoo.

4. Xaus

Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws, kho qhov kub thiab lub sijhawm yuav tsum txiav txim siab los ntawm ib puag ncig kub thiab av noo, ua yeeb yaj kiab thiab ua haujlwm nplaum.
