I-EVA Hot Melts yokupakishwa

Ukuncibilika okushisayo kwe-EVA kokupakishwa kwethenjwa kuyo yonke imboni ngokudala ama-fiber-amabhondi okudabula ku-kraft, ubumba{1}}amabhodi anamekwe kanye nama-laminated board, kanye ne-TH{3}}103E encane-ibanga le-flake yakhelwe ngokukhethekile amawindi okukhiqiza{6} anesivinini esimaphakathi. Le hot melt ye-EVA yokupakishwa inikeza isikhathi esimaphakathi esimaphakathi namabomu: eside ngokwanele ukuvumela opharetha babeke kabusha noma bafake isikwele{15}amakesi aphezulu ahamba ngo-15–35 m min⁻¹, nokho ashesha ngokwanele ukufinyelela amandla okubamba phakathi nama-8–12 s ngakho abathumeli akudingeki banwetshwe. Emazingeni okushisa anconywayo angu-170℃ingcina ikhombisa ukuncibilika kwe-viscosity engu-4000–6000 cps{16}}ezacile ngokwanele ukuze zondle kahle ngamaphampu agiya, ama-slot nozzles noma amakhanda esifutho esivunguzayo ngaphandle kokuvuza amathe, nokho i-viscous ngokwanele yokuhlala endaweni engaphansi, ivimbela ukucwiliswa{17}okuncane{17}kuqhathaniswa{17} aphansi{20}ama-viscosity seals. I-aggressive tack ithuthukisa ukubamba ngokushesha ebhodini le-linerboard eligaywe kabusha, B-umtshingo, E-umtshingo kanye nesitoko sokuthenga esinethezekile{23}}sezibambo zesikhwama, kuyilapho i-vinyl eguquguqukayo{28}}i-acetate backbone idonsa ukushaqeka futhi igcina amandla e-peel ku- -20℃ukuya +60 ku-logistic degree. I-TH-i-103E inikezwa njengothuli-olungenalo uthuli, ama-chips amancane afanayo{36}}ancibilika ngokushesha nangokulinganayo, eqeda ukwakheka kwe-char kanye nokunciphisa isikhathi sokulungiswa kwamapayipi, izihlungi namathangi ancibilikayo. Ngokwemvelo, ukwakheka kuyi-polymer ehlanzekile, encibilikayo{38}engenazo izinsimbi ezisindayo, i-formaldehyde noma i-phthalate plasticisers, ehlangabezana kokubili ne-FDA 21 CFR 175.105 kanye neziqondiso zokudla ze-EU 10/2011{39}}zokuxhumana, ukuze amabhrendi akwazi ukumemezela amaphakheji awo ngokuluhlaza ngempela. Okwefolda-yejubane-ama-gluer, ama-carton sealer aphakathi,{42}}izandla{42}}olayini bezikhwama ezizenzakalelayo{44}}nezibambo{45}}zenkampani yenethiwekhi, i-TH-103E iletha imayela elilinganisiwe, ubuhlakani kanye neziguquli ezinokuthula kwengqondo zifuna ukunamathela kwesimanje.

Amashadi ashisayo: I-eva eshisayo iyancibilika ukuze ifakwe, i-China Eva iyancibilika yabakhiqizi bokufaka, abahlinzeki, imboni
