IImvelaphi yoShishino: Iindlela ezimbini eziphambili zeGlobal Flexible Packaging Laminating Adhesives
Kwicandelo lokupakisha eliguquguqukayo kakhulu lokutya, iikhemikhali zemihla ngemihla, kunye namayeza, i-lamination ye-aluminium foil enemigangatho emithathu ye-PET+AL+PE yeyona ndlela isetyenziswa kakhulu yokupakisha ukumelana ne-oxygen ephezulu kunye neempawu zokuthintela ukukhanya. I-laminating adhesive ilawula ngokuthe ngqo ukumelana kwemveliso egqityiweyo ne-delamination, i-bubbling, kunye ne-retort billing, kunye nokhuseleko lokutya kunye nokuthobela indalo. Okwangoku, kukho iinkqubo ezimbini eziphambili ezikhoyo kushishino: i-polyurethane adhesives yendabuko eyomileyo esekelwe kwi-solvent kunye nesizukulwana esitsha se-polyurethane adhesives ezingenazo i-solvent. Ezi nkqubo zimbini zibonisa umahluko omkhulu kwixabiso, ukhuseleko lwendalo, ukusebenza kwemveliso, kunye nokuguquguquka komgca wemveliso.
Ishishini lokupakisha kwiimarike zaseRashiya naseCIS litshintsha. Ngowama-2026, izinga lokuphinda kusetyenziswe ukupakisha elinyanzelekileyo liza kufikelela kwi-75%, ngelixa imithetho ephathelele ukukhutshwa kwe-VOC (Volatile Organic Compounds) kunye nokhuseleko lokuqhagamshelana nokutya iyaqhubeka nokuqina. Iifektri ezininzi zokupakisha zasekuhlaleni ziyayiphelisa imigca yemveliso emidala esekwe kwi-solvent eyomileyo kwaye zitshintshela kwiinkqubo ze-lamination ezingena-solvent. Umboniso ozayo weRosUpack eMoscow uza kubonisa i-lamination eluhlaza engena-solvent njengeyona ndlela iphambili yobuchwepheshe.
IIIzincamathelisi zokuLaminate eziSekwe kwiSolvent ezomileyo: Iingenelo kunye namanqaku entlungu
Imigaqo-siseko
Izincamathelisi ze-polyurethane ezisekelwe kwisinyibilikisi zinomxholo oqinileyo we-30%–40% kuphela kwaye zixhomekeke kwizinyibilikisi ze-organic ezifana ne-ethyl acetate ukuze zinyibilike kwaye zilungise i-viscosity. Emva kokugquma, zifuna i-oven ende ukuze zome ngobushushu obuphezulu ukuze ziphelise ngokupheleleyo isinyibilikisi ngaphambi kokuba zicinezele ii-substrates kunye.
1. Iingenelo ezikhoyo
2. Iintsilelo Ezibulalayo Ezingenakuphepheka
IIIIzincamathelisi zokuLaminating ezingenazo izinyibilikisi: Isisombululo esiPhambili
Izincamathelisi ezingenazinyibilikisi ziyinkqubo ye-polyurethane enamacandelo amabini enomxholo oqinileyo oyi-100%.Kangda WD8262sisincamathelisi sokuqala esikhethekileyo saseTshayina esingenazinyibilikisi esaphuhliswa ngokukodwa kwimeko ye-PET+AL+PE yefoyile ye-aluminium eneeleya ezintathu.
1. Iingenelo eziPhambili zoKhuphiswano
Ihambelana nemigaqo-nkqubo yaseRashiya yokunciphisa ikhabhoni ka-2026. Inciphisa ukusetyenziswa kwamandla nge->60% kwaye inciphisa ingxolo ukuya kwi-70-75dB.
Akukho ntsalela yesinyibilikisi. Ayimelani nobushushu obuphezulu obuyi-121°C imizuzu engama-40. Ilungele inyama, ukutya kwezilwanyana zasekhaya, kunye neengxowa zonyango.
I-WD8262 ayisombululi amandla aneleyo okuxobuka kwefoyile. Yenzelwe ifoyile ye-aluminiyam ebhityileyo eyi-7μm ukuze inciphise amazinga okukrazula.
Ukusetyenziswa kwezithako ezisebenzayo eziyi-100%. Akukho mfuneko yokugcina isinyibilikisi kwaye kunciphisa kakhulu ukusetyenziswa kwamandla okufudumeza.
2. Amanqaku oLawulo lweeNkqubo zokuncamathelisa ezingenasombululo
- I-substrate Ngaphambi konyango:Unyango lweCorona kwiPET; uxinzelelo lomphezulu ≥38mN/m kwi-AL.
- Ulawulo loxinzelelo olwahlukileyo:90–110N kwi-PET; 40–70N ephantsi kwi-7μm AL ukuthintela ukuqhekeka okuncinci.
- Ukwaleka kunye nokuLamination:Ubunzima yi-3–5g/m². Inkqubo yokugquma i-lamination enamanyathelo amabini iyimfuneko.
- Iinkcukacha zokuphilisa:Ubushushu obungaguqukiyo buyi-40–50°C kangangeeyure ezingama-24–48.
IVIingcebiso zoKhetho kwiMarike yaseRashiya
Ingagcina iinkqubo zokunyibilikisa ezomileyo okwethutyana kwiinguqu zexesha elifutshane, kodwa kufuneka icwangcise ukuguqulwa komoya ophumayo ukuze ikwazi ukumelana nokunyuka kweentlawulo zokusingqongileyo.
Kucetyiswa kakhulu ukusebenzisa oomatshini beKangda WD8262 + abangenazo izinyibilikisi. Isombulula ukuqhekeka kwefoyile, ukususwa kwefoyile, kunye namabala amhlophe.
Iimpawu ezingenazo izinyibilikisi zihambelana nemigangatho yokusingqongileyo ye-EU/Russia, ziqinisekisa uphicotho-zincwadi olulula lweenkqubo zokubonelela ngempahla kunye nokuthintela ilahleko yembuyekezo.
VIindlela Zoshishino Lwexesha Elizayo
Izinga lokungena kwe-lamination engena-solvent kwimarike yokupakisha eguquguqukayo yehlabathi liyaqhubeka nokunyuka. I-RosUpack yaseMoscow ka-2026 isebenza njenge-weather vane kwishishini lokupakisha laseMpuma Yurophu, apho itekhnoloji ye-lamination ye-aluminium-plastic eluhlaza engena-solvent iya kuba yeyona nto iphambili. Kubavelisi bokupakisha baseRashiya, ukukhetha i-adhesives zasekhaya (zaseTshayina) ezingena-solvent ezingenayo i-solvent akunciphisi nje iindleko ezibanzi kodwa kukwahlangabezana nemigaqo eqinileyo yokusetyenziswa kwakhona kunye ne-VOC, imisela inzuzo eyahlukileyo yokhuphiswano kwicandelo lokupakishwa kokutya, iikhemikhali zemihla ngemihla, kunye namayeza.
