Ulawulo lokuvuthwa: ukuvuthwa kukwabizwa ngokuba kukunyanga, yinkqubo yokubeka ifilimu edityaniswe kwi-oveni (igumbi lokuvuthwa), ukuze eyona arhente iphambili yokuncamathelisa i-polyurethane, i-agent ephilisayo yokusabela i-crosslinking kwaye idityaniswe ne-substrate surface interaction. .Injongo ephambili yokunyanga kukwenza i-arhente ephambili kunye ne-ejenti yokunyanga ngexesha elithile ukuba iphendule ngokupheleleyo ukufezekisa amandla adibeneyo adibeneyo;okwesibini, ukususa indawo yokubilisa ephantsi yentsalela ye-solvent, njenge-ethyl acetate, njl.
Ulawulo lokuvuthwa ikakhulu kulawulo lobushushu bokuvuthwa kunye nexesha lokuvuthwa.Ixesha lokuvuthwa kweqondo lokushisa lokuvuthwa lichongwa ngokusebenza kwe-adhesive esetyenzisiweyo kunye neemfuno zokugqibela zokusebenza kwemveliso.Iindidi ezahlukeneyo zebhinder zinamaqondo obushushu ahlukeneyo kunye namaxesha.Iqondo lobushushu lokuvuthwa liphantsi kakhulu, ngaphantsi kwe-50 ℃, ukusabela kokuncamathelisa kucotha kakhulu;iqondo lobushushu lokuvuthwa liphezulu kakhulu, i-substrate film additives precipitation, ichaphazela ukusebenza kwefilimu ehlanganisiweyo kunye nokwandisa ivumba, njengexesha lokuvuthwa lide kakhulu liya kuchaphazela ukusebenza kwefilimu edibeneyo kunye nokwandisa ivumba, elibangelwa ikakhulu yimvula yokucubungula. uncedo kwifilimu ye-polyethylene.
Umsebenzi wegumbi lokuvuthwa: Kukubeka ifilimu edityaniswe kwigumbi lokubhaka (igumbi lokuvuthwa), ukuze eyona arhente iphambili yokuncamathelisa i-polyurethane, i-agent ephilisayo i-reaction cross-linking kwaye idityaniswe yinkqubo ye-substrate surface interaction. .Injongo ephambili yokuvuthwa kukwenza i-arhente ephambili kunye ne-ejenti yokunyanga iphendule ngokupheleleyo kwixesha elithile ukuze kuzuzwe amandla adibeneyo adibeneyo;okwesibini, ukususa i-solvents eseleyo kunye neqondo eliphantsi lokubilisa, njenge-ethyl acetate, njl., Ukunciphisa inani le-solvent ridue kunye nokunciphisa iphunga.
Iimeko zokuvuthwa nazo zixhomekeke kwezi zinto zilandelayo.
I-1, i-PET, i-BOPA, i-AL, i-CPP kunye nezinye iifilimu ngenxa yokumelana nokushisa okulungileyo, ukushisa okuphezulu kwe-shrinkage, ubushushu bokuvuthwa bunokwenyuka.Kwaye i-LDPE, BOPP, EVA kunye nolunye ubushushu bokuvuthwa alukwazi ukuba phezulu kakhulu;imeko jikelele 50 ℃ - 65 ℃ phakathi.
I-2, ixesha lokuvuthwa kweemveliso ezinexabiso eliphezulu leglue lide.
I-3, ixesha lokuvuthwa kweemveliso ngendlela yeefilimu zefilimu zingancitshiswa ngokufanelekileyo.
I-4, ixesha lokuvuthwa kweemveliso ezineethenda ze-convex ze-longitudinal zingandiswa.
I-5, ubukhulu befilimu, ububanzi befilimu xa kufanelekile ukwandisa ixesha lokuvuthwa.
I-6, ukwenzela ukunciphisa inani le-solvent eseleyo inokwandiswa ngokufanelekileyo ixesha lokuvuthwa.
I-7, ngokusetyenziswa kwemveliso ukulungiswa okufanelekileyo kwexesha lokuvuthwa.
Kukwakho nokuvuthwa okukhawulezileyo ukulawula imveliso.Thatha ifilimu edibeneyo eveliswe nje malunga ne-1 yemitha ubude, ububanzi obugcweleyo, ibekwe kwi-oven kwi-80 degrees imizuzu engama-30, ekuhloleni ukubonakala kwayo kunye nemeko yokuqala yokuhluma i-viscosity, ukufumanisa kwangethuba iingxaki kunye namanyathelo.Oku kukwayinxalenye eyimfuneko kulawulo lwenkqubo yokulatyulwa komileyo.
Kukho ezi mfuno zilandelayo zegumbi lokuvuthwa.
I-1, ubungakanani kunye nendawo yegumbi lokuvuthwa kufuneka lakhiwe ngokuhambelana nokugcinwa kwe-turnover, ukuququzelela ukungena kunye nokuphuma komqulu wefilimu, umnyango kufuneka uvuleke lula.
2, ukuphakama kwegumbi lokuvuthwa ngokuqhelekileyo kwi-2-2.5 yeemitha, phezulu kwinqaba, ukushiya i-5-10 cm ukuya kwimingxuma yomoya, kunokuba ngqo ngaphandle, okanye ukongeza ifestile encinci yokukhupha rhoqo, indima kukuba ukukhupha ivumba legumbi lokuvuthwa.
I-3, iishelufu zegumbi lokuvuthwa zingabekwa tyaba okanye uhlobo lwe-shelf-dimensional-dimensional, kuxhomekeke kwiimeko zothutho zeshishini ngalinye, kodwa kungekhona ifilimu yomqulu ngokuthe tye okanye ilele phantsi.
I-4, iindonga ezine zegumbi lokuvuthwa, iingcango, uphahla kunye nokunye ukufakwa kwe-insulation, ngokuqhelekileyo kusetyenziswa i-perlite, ibhodi ye-foam, njl., umphumo kukunyusa ixesha lokugquma, ukonga umbane, ukunciphisa iindleko kunye nobushushu obujikelezayo.
I-5, Ukulawula ukushisa.Igumbi lokuvuthwa linokufudunyezwa ngombane, umphunga, ukufudumeza, njl., kungakhathaliseki ukuba luhlobo luni lokufudumeza, kufuneka luxhotyiswe ngezixhobo zokulawula ubushushu, kwigumbi kufuneka libe nethemometha yemercury ukuvavanya ukuba ubushushu kunye nokuseta okufanayo.
Guangdong Lebei Packing Co.,Ltd.idlulile i-QS, i-SGS, i-HACCP, i-BRC, kunye ne-ISO certifications.Ukuba ufuna ukwazi ngakumbi kwaye unenjongo yokuyalela iingxowa, nceda uqhagamshelane nathi.Siza kukubonelela ngenkonzo elungileyo kunye nexabiso elifanelekileyo.
