Kev tshuaj xyuas ntawm qhov ua rau foaming thaum qhib kua nplaum:
1) Qhov sib txawv ntawm cov roj hmab rollers tsis sib npaug;
2) Cov nplaum muaj cov av thiab agglomeration;
3) Cov menyuam corrugating yog hnav tiag tiag;
4) Pib lub corrugator tom qab nws nres;
5) Muaj cov khoom sib txawv ntawm cov scraper thiab cov roj hmab cov menyuam;
6) Kev sib txuas lus cuav
1. Cov nplaum viscosity tsis txaus;
2. Cov kua nplaum siv tsawg heev;
3. Adhesive deterioration;
4. Qhov ceev ntawm lub tshuab corrugating yog ceev heev;
5. Qhov ceev ntawm lub tshuab corrugating yog qeeb heev;
6. Lub siab cov menyuam ntawm lub corrugator tsis sib npaug;
Txoj hauv kev txhim kho:
① A flute 4.5mm, B flute 2.8mm;
② Keep the adhesive pure and clean;
③ The corrugated roller must be replaced after the production volume reaches the limit;
④ The corrugating machine should not be restarted for more than 3 minutes after it is stopped;
⑤ Clean once per shift;
⑥ False bonding improvement method
1) Adhesive viscosity tsis txaus: 60-90 vib nas this hauv lub caij ntuj no, 90-120 vib nas this nyob rau lub caij ntuj sov;
2) Cov kua nplaum siv yog 1/3 ntawm qhov dav ntawm corrugated sab saum toj, uas yog, A corrugation yog 1.2 hli, thiab B thiab C corrugation yog 1 hli;
3) Tom qab cov nplaum sib xyaw, lub sijhawm cia yog 48 teev nyob rau lub caij ntuj sov thiab ib lub lis piam hauv lub caij ntuj no;
4) Qhov kub ntawm corrugating yob yog 150-170 ° C, thiab lub tshuab ceev yog tswj ntawm 70 m / min;
5) Qhov kub ntawm corrugating yob yog 150-170 degree, thiab lub tshuab ceev tsis tuaj yeem qis dua 25 m / min;
6) Kho lub tog raj kheej siab rau 0.4-0.6Mpa;
