Yuav ua li cas txo cov kuab tshuaj residues nyob rau hauv cov zaub mov ntim printing?

Qhov teeb meem ntawm cov kuab tshuaj residue ib txwm yog ib qho teeb meem nyuaj rau cov tuam txhab number case. Lub teb chaws twb tau teev tseg tias cov seem ntawm cov kuab tshuaj benzene yuav tsum qis dua 3㎎/㎡ nyob rau hauv cov kev cai tu cev ntawm BOPP/PE composite ntim. Yuav ua li cas txo cov seem ntawm cov kuab tshuaj nyob rau hauv txhuam ntawm cov zaub mov ntim tshuab luam ntawv tau dhau los ua ib qho tseem ceeb rau kev txiav txim siab rau ntau lub tuam txhab number case.

1. Ntawm peb cov resins EVA-40W, MP-45 thiab CL-PP, CL-PP feem ntau muaj cov kuab tshuaj ntau tshaj, thiab EVA-40W muaj cov kuab tshuaj tsawg tshaj plaws, yog li nws tuaj yeem lav lub zog sib xyaw. Hauv qee qhov xwm txheej, cov ntsiab lus ntawm CL-PP tuaj yeem raug txo kom tsim nyog thiab cov ntsiab lus ntawm EVA-40W tuaj yeem nce ntxiv.

2. Xaiv qhov tsim nyog CL-PP. Tus nqi seem ntawm cov kuab tshuaj los ntawm CL-PP ntawm cov chaw tsim khoom sib txawv hauv cov kua nplaum sib txawv sib txawv heev. Yog tias tus nqi tsim nyog tau txais, PP803MWS tsim los ntawm Nippon Ntawv tuaj yeem siv. Nyob rau hauv tib qhov ntau npaum li cas, feem ntau nws tuaj yeem txo mus rau 50 feem pua.

3. Thaum yaj EVA-40W, MP-45 thiab CL-PP, ntxiv ib feem ntawm ethyl ester thiab residual kuab tshuaj txo tus neeg sawv cev tuaj yeem txo qhov seem ntawm toluene cov kuab tshuaj nyob rau hauv cov kua nplaum zaj duab xis.

4. Tshawb xyuas seb cov kuab tshuaj siv rau tus number case thiab cov kuab tshuaj siv los ntawm cov xovxwm luam ntawv puas yog dawb huv. Yog tias muaj me me ntawm cov kuab tshuaj kub kub, nws yuav ua rau cov khoom seem ntawm cov kuab tshuaj siab dhau, thiab tseem ua rau cov ntawv luam tawm muaj ntxhiab tsw phem.

5. Kho nyob rau hauv tus txheej txheem ntawm printing thiab compounding:

①Thaum npaj cov kuab tshuaj dilution, siv cov toluene hnyav npaum li sai tau. Koj tuaj yeem xaiv cov kuab tshuaj sib xyaw ntawm toluene: acetic acid: butanone =2: 5: 3;

②Nyob rau hauv cov txheej txheem luam ntawv, ua kom cov pa tawm hauv qhov ziab ziab ntawm lub tshuab luam ntawv, thiab tsim kom muaj qhov kub ntawm qhov ziab kom qhuav. Yog tias muaj kev tso cai, qhib qhov ziab kom qhuav rau ntau qhov ziab tom qab cov ntawv luam tawm dawb;

③Nyob rau hauv cov txheej txheem ntawm luam ntawv, viscosity ntawm tus number case yuav raug txo kom tsim nyog.
