1. YintoniIfilimu enamathelayo ye-EVA Hot Melt Adhesive?
Yinto eqinileyo, enamathelayo ye-thermoplastic efumaneka kwifilimu ebhityileyo okanye kwimo yewebhu.
I-polymer yayo esisiseko ephambili yiI-Ethylene Vinyl Acetate (EVA)i-copolymer, edla ngokudityaniswa nee-resin eziqinisayo, ii-waxes, iziqinisi, kunye nezinye izinto eziguqula izinto.
Isebenza ngobushushu noxinzelelo, inyibilika ukuze yenze i-glue eqinileyo xa ipholile.
2. Iimpawu eziphambili:
I-thermoplastic:Iyanyibilika xa ifudunyezwa kwaye iqine xa ipholile.
Ayinazo izinyibilikisi kwaye inobuhlobo nokusingqongileyo:Ayinazo iikhompawundi ze-organic eziguquguqukayo (ii-VOC), nto leyo eyenza ukuba icoceke kwaye ikhuseleke kunezincamathelisi ezisekelwe kwisinyibilikisi.
Ukudibanisa Okukhawulezayo:Ukusebenza kunye nokubopha kwenzeka ngokukhawuleza xa kufakwa ubushushu kunye noxinzelelo.
Isicwangciso sokuqala esihle:Inika ukubambelela okuqinileyo kokuqala xa inyibilikisiwe.
Ukuguquguquka:Iifilimu ezisekelwe kwi-EVA zihlala ziguquguquka kakuhle emva kokubopha, zihambelana kakuhle neziseko.
Uluhlu Olubanzi Lokunamathela:Inamathela kakuhle kwizinto ezahlukeneyo ezinemingxuma kunye nezingenamingxuma (amalaphu, amagwebu, iplastiki, umthi, isinyithi).
Ukucutshungulwa okulula:Iyahambelana nezixhobo ze-lamination kunye ne-bonding ezisemgangathweni zoshishino.
Isebenza kakuhle emalini:Ngokubanzi isisombululo sokuncamathelisa esingabizi kakhulu xa sithelekiswa nezinye iintlobo ze-HMAM (ezifana ne-PA, i-TPU).
3. Izicelo eziphambili:
Impahla yelaphu nempahla:
Amalaphu okugquma (umz., ii-interlinings zeekhola, ii-cuffs, ii-waistbands).
Ukutywina umphetho kunye nomthungo.
Ukuncamathisela ii-appliqués, iipetshi, kunye neelebhile.
Ukubopha amalaphu angalukwanga (umz., kwiimveliso zococeko, izihluzi).
Izinto ezidibanisa izihlangu ezifana neetoe puffs, iikhawuntara, ii-insoles, kunye nee-linings.
Ukuncamathisela i-uppers kwi-midsoles okanye kwi-outsoles (idla ngokudityaniswa nezinye izinto zokuncamathisela).
Izikhumba kunye neempahla ezenziwe ngokwenziwa ezilaminethiweyo.
Ukupakisha:
I-lamination ekhethekileyo yokupakisha (umz., iphepha/ifoyile, iphepha/iplastiki).
Ukutywina iibhokisi kunye neebhokisi.
Ukwenza iibhokisi eziqinileyo.
Iimoto kunye nokuThutha:
Izinto zokuhlobisa zangaphakathi ezidibanisayo (ii-headliners, iiphaneli zomnyango, iikhaphethi, ii-trunk liners).
Amalaphu okugquma ade abe ngamagwebu okanye izinto ezidityanisiweyo.
Ukubopha kunye nokutywina imiphetho.
Ifenitshala kunye nempahla yokuhombisa:
Ilaphu elidibanisa i-foam padding.
Ukutywinwa komphetho kunye nokugqunywa kwelamination kwiimatrasi kunye neekhushini.
Imiphezulu yokuhombisa enelaminethi.
IiLaminate zoBugcisa kunye neeLaminate zeMizi-mveliso:
Iileya zokubopha kwimidiya yokucoca.
Ii-geotextile zokugquma.
Ukudala izinto ezidityanisiweyo ezisetyenziselwa ukusetyenziswa kwemizi-mveliso eyahlukeneyo.
Izinto zokwenza kunye nemisebenzi yezandla:(Iindlela ezisezantsi zokunyibilika)
Izinto zokubopha kwiiprojekthi zokuzonwabisa.
Imisebenzi yezandla kunye nemihombiso yelaphu.
4. UkucubungulaIindlela:
5. I-Flatbed Lamination:Ukusebenzisa iipleyiti ezishushu.
Ukugquma okuqhubekekayo kweRoll:Ukusebenzisa iirola zekhalenda ezifudunyeziweyo okanye iirola ze-nip.
Ukudibanisa iContour:Ukusebenzisa izixhobo ezishushu ezikhethekileyo kwiimo ezithile.
Ukusebenza kwe-Ultrasonic:Ukusebenzisa amandla e-ultrasonic ukunyibilikisa ifilimu kwindawo (ayiqhelekanga kakhulu kwi-EVA kunezinye iintlobo).
Inkqubo:Beka ifilimu phakathi kwezinto ezisetyenziswa phantsi komhlaba -> Faka ubushushu (ukunyibilikisa ifilimu) -> Faka uxinzelelo (ukuqinisekisa ukuba idibana kwaye imanzi) -> Phola (ukuqina kunye nokwakheka kwebhondi).
6. Iingenelo ze-EVA HMAM:
Icocekile kwaye kulula ukuyiphatha (akukho ngxolo, ayinathuli).
Ubukhulu obuhambelanayo kunye nokusasazwa kweglue.
Akukho xesha lifunekayo lokumisa/lokunyanga emva kokubopha.
Uzinzo oluhle kakhulu lokugcina phantsi kweemeko eziqhelekileyo.
Ulungelelwano oluhle lokunamathela, ukuguquguquka, kunye neendleko.
Amaqondo obushushu okucubungula aphantsi kakhulu xa kuthelekiswa namanye ama-HMAM.
6. Imida/Izinto eziqwalaselwayo:
Ubuthathaka bobushushu:Iibhondi zinokuthamba okanye zingaphumeleli xa kushushu kakhulu (ngokuvamile zinqunyelwe ku <~65-80°C / 150-175°F ukusetyenziswa rhoqo, kuxhomekeke kwindlela ezisetyenziswa ngayo).
Ukumelana neekhemikhali:Ngokubanzi ukuxhathisa okungekuhle kwizinyibilikisi, iioyile, kunye neekhemikhali ezinamandla.
Ukuqhekeka:Xa kuthwalwa umthwalo ongapheliyo, ingakumbi kumaqondo obushushu aphezulu, iindawo ezidibeneyo zinokurhubuluza (ziguquguquke kancinci).
Ukumelana nokufuma:Ukusebenza kunokwahluka ngokuxhomekeke kwindlela eyenziwe ngayo; ayingeni manzi ngokwemvelo njengezinye iifilimu zePUR.
Ukuhambelana kweSubstrate:Nangona ibanzi, ukunamathela kwiiplastiki ezinamandla aphantsi kakhulu (ezifana ne-PP, i-PE) kudla ngokufuna unyango lomphezulu okanye iindlela ezithile.
Isiphelo:
Ifilimu ye-EVA Hot Melt Adhesive sisisombululo esiguquguqukayo, esingabizi kakhulu, nesisebenziseka lula esisetyenziswa kakhulu kwiimpahla zelaphu, izihlangu, ukupakisha, izinto zangaphakathi zeemoto, ifenitshala, kunye ne-lamination yemizi-mveliso. Amandla ayo aphambili akwindlela elula yokucubungula, ukuguquguquka okuhle, ukuqina kokuqala okuqinileyo, kunye nokungabi naso isinyibilikisi. Nangona ubushushu bayo kunye nokumelana kwayo neekhemikhali kubeka imida ethile, ihlala ilukhetho oluphambili kwizicelo apho ezi zinto zingabalulekanga kwaye ukusebenza kakuhle kweendleko kubaluleke kakhulu.
