Nyob zoo cov neeg siv khoom muaj txiaj ntsig ntawm Beidemeike/Solvent-Lamination dawb:
Lub caij ntuj sov nyob ntawm no, thiab ambient kub thiab av noo yog nce tsis tu ncua. Rau cov kuab tshuaj- cov txheej txheem lamination dawb, qhov kub thiab txias siab yog qhov tseem ceeb tshaj plaws sab nraud cuam tshuam rau cov khoom tiav tiav, ua rau cov neeg siv khoom tsis txaus siab thiab cov khoom seem.
Raws li lub chaw tsim khoom ntawm cov kuab tshuaj- cov tshuab lamination dawb, Bedmec tau sau cov lus qhia tshwj xeeb rau lub caij ntuj sov lamination los pab koj kom ruaj khov thiab txo qis.
I. Vim li cas cov teeb meem feem ntau tshwm sim thaum lub caij ntuj sov?
Cov kuab tshuaj-dawb lamination feem ntau siv NCO- hom isocyanate adhesives (A-type adhesive), uas nws cov khoom siv tshuaj ua rau lawv rhiab heev rau cov dej noo:
• NCO pawg + noo noo nyob rau hauv cov huab cua → react rau CO₂ los yog polyurea
• Kub kub → ntau ntau ntawm additives (slip agents, antistatic agents) nyob rau hauv cov zaj duab xis yog tso tawm sab nraud.
Nyob rau hauv luv luv: Yog tsis tswj qhov kub thiab av noo nyob rau hauv lub caij ntuj sov, lamination yog nyuaj rau stabilize.
II. Peb qhov teeb meem tshwm sim los ntawm qhov kub thiab txias
Tus kheej -Table Inspection Reference
| Ua rau | Reaction Mechanism | Cov tsos mob / kev ua haujlwm tsis zoo | Nws Yuav Rov Qab Los? |
|---|---|---|---|
| Cov av noo ntau dhau | NCO + H₂O → CO₂↑ | Cov pob dawb, npuas, lossis pinholes hauv lub laminate | ❌ Tsis yog - cov tsos mob tsis zoo yog irreversible |
| Kub siab tshaj 30℃(86℃F) | Ntau dhau kev tsiv teb tsaws ntawm zaj duab xis additives rau saum npoo | Txo daim ntawv cog lus lub zog, lub hnab delamination thaum hloov | ✅ Yog - kev ntxuav saum npoo av nrog cov kuab tshuaj uas tsim nyog tuaj yeem pab rov qab adhesion |
| Ncua sij hawm rau High Humidity | NCO + H₂O → Solid Polyurea Formation | Tsis zoo cua sov- sealing kev ua tau zoo, cov khoom nyuaj ntawm lub laminate nto | ❌ Tsis yog - cuam tshuam cov yob feem ntau suav tias yog seem |
III. Kev txiav txim siab sai: Nws puas yog zaj duab xis nag lossis dej tsis ua haujlwm polyurea?
Txoj kev ua tau zoo: So qhov chaw tsis zoo nrog cawv lossis acetone.
| Soj ntsuam qhov tshwm sim | Kev kuaj mob | Thaum tshav kub kub-Hloov rov qab | Pom zoo ua |
|---|---|---|---|
| ✅Pab tuaj yeem kho tau | Zaj duab xis additive migration (nto blooming) | Rov qab mus rau qhov qub tom qab ntxuav | Rov ua haujlwm dua |
| ❌ Tsis tuaj yeem tshem tawm | Polyurea tsim (nplaum cov tshuaj tiv thaiv nrog noo noo) | Kev ua tsis tiav | Qhwv tam sim ntawd |
Polyurea yog irreversible; tsis txhob harbor tej illusions txog kev cawm nws los ntawm kev kho.
IV. Environmental Control Standards (pom zoo los ntawm Beidemeike)
| Parameter | Txheem tus nqi | Tseem ceeb txwv |
|---|---|---|
| Cov av noo | Tsawg dua lossis sib npaug li 60% RH | 65% RH |
| Kub | < 30°C | 32 degree |
✅ Qhov Zoo Tshaj Plaws: Lub tshuab laminating yog nyob rau hauv qhov kub thiab txias - thiab av noo - tswj chav huv nrog cov kev faib tawm ywj pheej.
✅ Cov txiaj ntsig: Kev txo qis ntawm plaub yam tsis xws luag: pob dawb, npuas, delamination, thiab polyurea.
V. Tsib lub tswv yim zoo rau kev tsim khoom kub thaum lub caij ntuj sov
Q1. Yuav ua li cas yog tias cov av luv luv tshaj tus qauv (65-75% RH)?
A1• Ntxiv cov txheej txheej kom tsim nyog (+10–20%)
• Txo cov tshuab laminating ceev (20–30%)
• Muab cov desiccant los yog dehumidifier me me nyob ze ntawm lub tank kua nplaum thiab sib tov lub taub hau.
Q2. Yuav ua li cas kom txias yam tsis muaj qhov kub thiab txias rhiav?
A2• Muab cov yeeb yaj kiab tso rau hauv qhov cua- lub tsev khaws khoom txias (20–25 degree) rau 12 teev ua ntej.
• Khaws cov kua nplaum hauv qab 25℃thiab tshem tawm tsuas yog thaum xav tau.
`• Ntxiv cov kiv cua mus rau qhov chaw unwinding thiab rewinding qhov chaw pab kom sov dissipation.
3. Q: Cov pob polyurea puas tuaj yeem khaws cia?
A: No.Polyurea yog ib qho thermosetting polymer uas tsis tuaj yeem decomposed los ntawm siab -kub curing. Nws raug nquahu kom txiav ncaj qha rau ntawm qhov tsis xws luag kom tsis txhob ntws mus rau hauv lub hnab - ua cov txheej txheem.
IV. Puas muaj qhov sib txawv tseem ceeb hauv siab -tej dej nag rau cov yeeb yaj kiab ua los ntawm cov khoom sib txawv?
| Khoom siv | Qib tsiv teb tsaws | Pom zoo Pretreatment |
|---|---|---|
| PE | Siab | So nrog cawv / Siv tsawg-migration PE zaj duab xis |
| CPP | Nruab nrab | Preheat thiab so ua ntej lamination |
| PET | Tsawg | Kev tu niaj hnub yog txaus |
| PA | Tsawg heev (tab sis noo noo-sensitive) | Tsom ntsoov rau kev tiv thaiv noo noo; siv tam sim ntawd tom qab unpacking |
V. Ob qhov yooj yim tshaj plaws thiab ua tau zoo tshaj plaws hauv lub caij ntuj sov:
• Dej cawv so ua ntej kev thauj khoom
• Txhua hnub ntsuas kub thiab av noo nyob rau hauv lub rhiav
VI. Ib - kab lus cov ntsiab lus ntawm Bedemek
- High -tej dej nag tuaj yeem tshem tawm, tab sis siab -cov av polyurea tsis tuaj yeem txuag nws.
- Kev tswj kub thiab av noo yog qhov tseem ceeb, thiab kev txo qis ceev ceev thiab cov kua nplaum ntxiv yog qhov zoo.
- Cov kuab tshuaj-dawb compounding tsis yog metaphysics, tab sis kev sib xyaw ua ke ntawm chemistry thiab ib puag ncig.
Beidemeikeyuav nrog koj mus siv lub caij ntuj sov smoothly.
