—-Guangdong Lebei Packaging Co., LTD.
Ngaba ucatshukiswa kukuba ibhegi edibeneyo oyenzayo ithande ukuphuka?Ngaba uyazazi izizathu zokuba kutheni ibhegi entsonkothileyo oyi-odoleyo kusenokwenzeka ukuba igqabhuke?Okulandelayo, vumela i-Guangdong Lebei Packaging Co., Ltd. ikuphendulele.
Zisixhenxe izizathu eziphambili.
Enye iqondo lokushisa lokutywinwa kwe-thermal linempembelelo ethe ngqo kumandla okutywinwa kwe-thermal.
Iqondo lokushisa elinyibilikayo lezinto ezahlukeneyo lichaza ngokuthe ngqo ubushushu obuncinci bokutywinwa kwe-thermal yengxowa edibeneyo.Kwinkqubo yokuvelisa, ngenxa yoxinzelelo lokutywinwa kwe-thermal, i-bag yenza isantya kunye nobukhulu be-substrate edibeneyo, iqondo lokushisa elichanekileyo lokutywinwa kwe-thermal lihlala liphezulu kuneqondo lokushisa lokunyibilika kwezinto ezishushu zokutywina.Okukhona usezantsi koxinzelelo lokutywinwa kwe-thermal, kokukhona iqondo lobushushu lokutywinwa liphezulu;Isantya esikhawulezayo, kokukhona ingqindilili imathiriyeli yefilimu ehlanganisiweyo, kokukhona inyuka iqondo lobushushu elifunekayo lokutywinwa lobushushu.Ukuba iqondo lokushisa lokutywinwa kwe-thermal lisezantsi kunendawo yokuthambisa yezinto zokutywinwa kwe-thermal, akunakwenzeka ukutywina ngokwenene umaleko wokutywinwa kwe-thermal kungakhathaliseki ukuba ukunyusa njani uxinzelelo okanye ukwandisa ixesha lokutywinwa kwe-thermal.Nangona kunjalo, ukuba iqondo lokushisa elitshisayo lokutywinwa liphezulu kakhulu, kulula ukulimaza i-extrusion etyhidiweyo yezinto zokutywina ezishushu kwi-welding edge, okubangelwa yinto "yokusika ingcambu", enciphisa kakhulu amandla okutywinwa okutshisa kwetywina kunye ukuchasana kwempembelelo yesikhwama.
Okwesibini, uhlobo, ubukhulu kunye nomgangatho we-thermal sealing layer material inefuthe eliqinisekileyo kumandla okutywinwa kwe-thermal.
Izinto ezisetyenziswa ngokuqhelekileyo ezishushu zokutywina zokupakishwa kwe-composite yi-CPE, i-CPP, i-EVA, i-adhesive eshushu enyibilikayo kunye nenye i-ionic resin co-extrusion okanye ifilimu edibeneyo edibeneyo.Ubukhulu bezinto zomaleko wokutywinwa kwe-thermal ziphakathi kwe-20 kunye ne-80 μ m, kwaye kwiimeko ezizodwa, ukuya kuthi ga kwi-100 ~ 200 μ m.Isixhobo esifanayo sokutywinwa kwe-thermal, amandla ayo okutywinwa kwe-thermal ayanda ngokunyuka kobunzima bokutywinwa kwe-thermal.Amandla okutywina ashushu ebhegi yokupheka afuneka ngokubanzi ukufikelela kwi-40 ~ 50 Newton, ngoko ke ubukhulu bezinto zokutywina ezishushu kufuneka zibe ngaphezu kwe-60 ~ 80 μ m.
Okwesithathu, ukufezekisa amandla afanelekileyo okutywinwa kwe-thermal, uxinzelelo oluthile lubalulekile.
Kwiingxowa zokupakisha ezikhanyayo kunye nezilula, uxinzelelo lokutywinwa kwe-thermal kufuneka lufikelele ubuncinane kwi-2kg / cm2, kwaye lunyuke ngokufanelekileyo ngokunyuka kobunzima obupheleleyo befilimu edibeneyo.Ukuba ukutywinwa koxinzelelo lobushushu akwanelanga, kunzima ukufezekisa ukudityaniswa kokwenyani phakathi kweefilimu ezimbini, okubangela ukutywinwa kobushushu bendawo akulunganga, okanye kunzima ukubamba amaqamza afakwe phakathi kwe-weld, ebangela ukuwelda okubonakalayo;Kakade ke, ubukhulu boxinzelelo lokutywinwa kobushushu alukho ngcono, ubushushu kufuneka bufaneleke ukuba bungamoshi i-welding edge, kuba izinto zokutywina ubushushu kumphetho we-welding zikwimeko etyhidiweyo, uxinzelelo oluninzi kulula ukulucudisa. kude inxalenye yesixhobo sokutywina ubushushu, ukwenzela ukuba i-weld edge yenze i-semi-cut state, i-weld seam i-brittle, kwaye amandla okutywinwa kobushushu ayancipha.
Okwesine, ukuba i-weld emva kokutywinwa okutshisayo ayipholiswanga kakuhle, ayiyi kuchaphazela kuphela ukubonakala kunye ne-flatness ye-weld, kodwa ibe nefuthe elithile kumandla okutywinwa kobushushu.
Inkqubo yokupholisa kukuphelisa inkqubo yoxinaniso loxinzelelo ngokubumba umthungo otyhidiweyo wokutywina weld weld kwiqondo lobushushu elisezantsi phantsi koxinzelelo oluthile.Ke ngoko, uxinzelelo alwanelanga, ukujikeleza kwamanzi okupholisa akulunganga, ubungakanani bokujikeleza akwanelanga, ubushushu bamanzi buphezulu kakhulu, okanye ukupholisa akufike ngexesha, kuya kukhokelela ekupholiseni kakubi, umphetho wokutywina ubushushu uyajika, kwaye amandla okutywinwa kobushushu ayancipha.
Okwesihlanu, ixesha lokutywinwa elitshisayo lichongwa ikakhulu ngesantya somatshini wokwenza ingxowa.
Ixesha lokutywinwa kwe-Thermal likwayinto ephambili echaphazela amandla kunye nokubonakala kokutywinwa kwe-weld.Ubushushu obufanayo bokutywina kunye noxinzelelo, ixesha lokutywina elishushu lide, ukudityaniswa komgangatho wokutywina okutshisayo kugcwele ngakumbi, ukudibanisa kuqina ngakumbi, kodwa ixesha lokutywina elishushu lide kakhulu, kulula ukubangela ukushwabana kwe-weld, kuchaphazela ukubonakala.
Okwesithandathu, kokukhona amaxesha okutywinwa kobushushu, kokukhona enyuka amandla okutywina ubushushu.
Inani lokutywinwa kwe-thermal longitudinal kuxhomekeke kumlinganiselo wobude obusebenzayo kunye nobude bengxowa, kunye nobude bokutywinwa be-longitudinal thermal bugqitywe linani leeseti zeyunithi yokutywinwa kwe-thermal transverse.Ukutywinwa okuhle okushushu, kufuna inani lamaxesha okutywinwa ashushu ubuncinci kabini.Kukho amaqela amabini emela eshushu kumatshini wokwenza ibhegi ngokubanzi, kwaye okukhona uphezulu ukuhlangana kwemela eshushu, kokukhona isiphumo esishushu sokutywina.
Ekugqibeleni, ifilimu edibeneyo kunye nesakhiwo esifanayo kunye nobukhulu, ukuphakama kwamandla okuhluthwa komgangatho odibeneyo, amandla amakhulu okutywinwa kwe-thermal.
Kwiimveliso ezinamandla aphantsi okuhlubula okudityanisiweyo, ukusilela kweweld kudla ngokuba kukuhluba okokuqala kwefilimu edibeneyo kumthungo we-weld, okukhokelela kumaleko wokutywina ongaphakathi ngokuzimeleyo aphethe amandla okutshabalalisa okutshabalalisayo, kwaye umphezulu wezinto zomaleko ulahlekelwa sisiphumo sokomeleza. , ngoko ke amandla okutywinwa kwe-thermal ye-weld ayancipha kakhulu.Ukuba amandla okuhluba okudityanisiweyo makhulu, ukuhlutywa kwamaleko aphakathi akuyi kwenzeka, kwaye ukomelela kokutywinwa kwe-thermal kulinganisiwe kukhulu kakhulu.
