1. KuyiniIfilimu Enamathelayo Eshisayo ye-EVA?
Kuyinto eqinile, enamathelayo ye-thermoplastic etholakala ngefilimu encane noma ngesimo sewebhu.
I-polymer yayo eyisisekelo eyinhloko yi-I-Ethylene Vinyl Acetate (EVA)i-copolymer, evame ukuhlanganiswa nama-resin okunamathela, ama-waxes, ama-stabilizer, nezinye izinto zokulungisa.
Isebenza ngokushisa nokucindezela, incibilike ukuze yakhe isibopho esiqinile sokunamathela lapho iphola.
2. Izakhiwo Eziyinhloko:
I-thermoplastic:Iyancibilika lapho ifudumala futhi iqine lapho iphola.
Ayinazo izinyibilikisi futhi inobungani nemvelo:Ayinazo izinto eziphilayo eziguquguqukayo (ama-VOC), okwenza ihlanzeke futhi iphephe kunezinamathelisi ezisekelwe ku-solvent.
Ukubopha Okusheshayo:Ukusebenza kanye nokubopha kwenzeka ngokushesha uma kusetshenziswa ukushisa kanye nengcindezi.
Isiqalo Esihle Sokuqala:Inikeza ukubamba okuqinile kokuqala uma kuncibilikiswa.
Ukuzivumelanisa nezimo:Amafilimu asekelwe ku-EVA ngokuvamile agcina ukuguquguquka okuhle ngemva kokubopha, evumelana kahle nezingxenye ezingaphansi.
Ububanzi Bokunamathela Okubanzi:Inamathela kahle ezintweni ezahlukahlukene ezinezimbobo nezingenazimbobo (izindwangu, amagwebu, ipulasitiki, ukhuni, izinsimbi).
Ukucubungula Okulula:Iyahambisana nemishini ejwayelekile yokubopha kanye neyokubopha yezimboni.
Kuqiza kahle:Ngokuvamile ikhambi lokunamathela elingabizi kakhulu uma liqhathaniswa nezinye izinhlobo ze-HMAM (njenge-PA, i-TPU).
3. Izicelo Eziyinhloko:
Izindwangu Nezingubo:
Izindwangu zokugquma (isib., ama-interlinings amakhola, ama-cuff, amabhande okhalweni).
Ukuvala umphetho kanye nomthungo.
Ukunamathisela ama-appliqués, ama-patches, namalebula.
Ukubopha izindwangu ezingalukiwe (isib., emikhiqizweni yokuhlanzeka, izihlungi).
Izingxenye zezicathulo ezibophayo njengezimbobo zezinyawo, amakhawunta, ama-insoles, kanye nama-lining.
Ukunamathisela izingxenye ezingenhla emaceleni aphakathi noma emaceleni angaphandle (ngokuvamile kuhlanganiswa nezinye izinto zokunamathisela).
Izikhumba nezindwangu zokwenziwa ezilaminayo.
Ukupakisha:
Ukufakwa kwe-lamination ekhethekile (isb., iphepha/i-foil, iphepha/ipulasitiki).
Ukuvala amabhokisi namabhokisi.
Ukwakha amabhokisi aqinile.
Izimoto kanye Nezokuthutha:
Izingxenye zokuhlobisa zangaphakathi ezibophayo (izigqoko zekhanda, amaphaneli eminyango, amakhaphethi, ama-trunk liner).
Izindwangu zokulamina zibe amagwebu noma izinhlanganisela.
Ukubopha nokuvala imiphetho.
Ifenisha kanye nezingubo zokugqoka:
Indwangu ebophayo ephepheni le-foam.
Ukuvala imiphetho kanye nokubopha ama-lamination kuma-matrasi kanye nama-cushion.
Izindawo zokuhlobisa ezilaminayo.
Izindwangu Zobuchwepheshe kanye nama-Laminate Ezimboni:
Izendlalelo zokubopha kwimidiya yokuhlunga.
Ama-geotextile e-laminating.
Ukudala izinto ezihlanganisiwe zokusetshenziswa okuhlukahlukene kwezimboni.
Izinto Zokuzenzela Nezobuciko:(Izinhlobo ze-melt point eziphansi)
Izinto zokubopha zamaphrojekthi okuzilibazisa.
Imisebenzi yezandla kanye nemihlobiso yendwangu.
4. UkucubungulaIzindlela:
5. I-Lamination Eyisicaba:Ukusebenzisa imishini yokucindezela eshisayo.
Ukugoqa Okuqhubekayo:Ukusebenzisa ama-rollers ekhalenda afudumele noma ama-nip rollers.
Ukubopha kwe-Contour:Ukusebenzisa amathuluzi akhethekile ashisayo ezimo ezithile.
Ukusebenza kwe-Ultrasonic:Ukusebenzisa amandla e-ultrasonic ukuncibilikisa ifilimu endaweni (akuvamile kakhulu kwi-EVA kunezinye izinhlobo).
Inqubo:Beka ifilimu phakathi kwezingxenye ezingaphansi -> Faka ukushisa (ukuncibilikisa ifilimu) -> Faka ingcindezi (ukuqinisekisa ukuthintana nokumanzisa) -> Phola (ukuqina nokwakheka kwesibopho).
6. Izinzuzo ze-EVA HMAM:
Ihlanzekile futhi kulula ukuyiphatha (akukho kungcola, ayinazintuli).
Ubukhulu obuhambisanayo kanye nokusatshalaliswa kwe-glue.
Akudingeki isikhathi sokomisa/sokuphola ngemva kokubopha.
Ukuqina okuhle kakhulu kwesitoreji ngaphansi kwezimo ezijwayelekile.
Ibhalansi enhle yokunamathela, ukuguquguquka, kanye nezindleko.
Amazinga okushisa okucubungula aphansi kakhulu uma kuqhathaniswa namanye ama-HMAM.
6. Imikhawulo/Okucatshangelwayo:
Ukuzwela kwezinga lokushisa:Ama-bond angathamba noma ahluleke emazingeni okushisa aphezulu (ngokuvamile anqunyelwe ku-<~65-80°C / 150-175°F ukusetshenziswa okuqhubekayo, kuye ngokuthi akhiwe kanjani).
Ukumelana namakhemikhali:Ngokuvamile ukumelana kahle nezinyibilikisi, uwoyela, kanye namakhemikhali anamandla.
Ukucasuka:Ngaphansi komthwalo oqhubekayo, ikakhulukazi emazingeni okushisa aphezulu, izingxenye eziboshiwe zingase zikhukhule (ziwohloke kancane kancane).
Ukumelana Nomswakama:Ukusebenza kungahlukahluka kuye ngokuthi kwenziwa kanjani; akuvimbeli manzi ngokwemvelo njengamanye amafilimu e-PUR.
Ukuhambisana kwe-Substrate:Nakuba kubanzi, ukunamathela kumapulasitiki anamandla aphansi kakhulu (njenge-PP, i-PE) kuvame ukudinga ukwelashwa kwendawo noma ukwakheka okuthile.
Isiphetho:
I-EVA Hot Melt Adhesive Film iyisisombululo sokubopha esisebenziseka kalula, esingabizi kakhulu, futhi esisebenziseka kalula esisetshenziswa kabanzi ezindwangu, ezicathulweni, ekupakisheni, ngaphakathi kwezimoto, ifenisha, kanye ne-lamination yezimboni. Amandla ayo ayinhloko alele ekucutshungulweni kwayo kalula, ukuguquguquka okuhle, ukuqina kokuqala okuqinile, kanye nokungabi namanzi anyibilikayo. Ngenkathi ukumelana kwayo nokushisa kanye namakhemikhali kubeka imikhawulo ethile, ihlala iyisinqumo esivelele sezinhlelo zokusebenza lapho lezi zici zingebalulekile futhi ukusebenza kahle kwezindleko kubaluleke kakhulu.
