Inkcazo: Eli phepha lihlalutya usetyenziso kunye nentsingiselo yophuhliso lwengxowa ye-solvent-free edityanisiweyo yobushushu obuphezulu, kwaye yazisa amanqaku aphambili olawulo lwenkqubo, kubandakanywa ukusetwa kunye nokuqinisekiswa komthamo wokugquma, uluhlu lokufuma kokusingqongileyo, ukusetwa kweparamitha yesixhobo. ukusebenza, kunye neemfuno zemathiriyeli ekrwada, njl.
Indlela yokutshisa kunye nokuvala inzala ikhona iminyaka emininzi.E-China, ngenxa yokuphuhliswa kade kwe-adhesives-free adhesives, phantse zonke zazisetyenziselwa ukuhlanganisa ukupakishwa kokupheka kokushisa okuphezulu.Ngoku, izinto zokuncamathelisa ezinganyibilikiyo ziqhube iminyaka elishumi yophuhliso eTshayina, nophuculo oluphawulekayo kwizixhobo, izinto ezikrwada, abasebenzi, kunye neteknoloji.Kumxholo wemigaqo-nkqubo yesizwe yokukhuselwa kokusingqongileyo, amashishini oshicilelo lwemibala aye adala indawo enkulu yophuhliso yokuncamathelisa i-solvent-free ukuze kufuneke inzuzo kunye nophuhliso, oluqhutywa ngumba wokwandisa umthamo wemveliso.Ngoko ke, ukugqunywa kwe-solvent free adhesives kuya kusanda. ebanzi, kwaye umphunga, inzala, kunye nokupakishwa yenye yazo.
1.Ingcamango yokupheka inzala kunye nokusetyenziswa kwe-adhesives-free adhesives
Ukupheka inzala yinkqubo yokutywina kunye nokubulala iintsholongwane kwizikhongozeli ezingangeni moya ngokufaka uxinzelelo kunye nokufudumeza.Ngokubhekiselele kwisakhiwo sesicelo, ukupakishwa kwe-steaming kunye ne-sterilization okwangoku kwahlulahlulwe kwiindidi ezimbini: iplastiki kunye nezakhiwo ze-aluminium-plastiki.Iimeko zokupheka zihlulwe zibe ngamanqanaba amabini: ukupheka kweqondo lokushisa eliphezulu (ngaphezu kwe-100° C ukuya ku-121° C) kunye nokupheka kokushisa okuphezulu (ngaphezulu kwe-121° C ukuya kwi-145° C).Izinto ezincamathelayo ezinyibilikayo zasimahla zinokuvala inzala yokupheka kwi-121° C nangaphantsi.
Ngokwemveliso esebenzayo, makhe ndazise ngokufutshane imeko yesicelo seemveliso ezininzi zaseKangda:
Isakhiwo sePlastiki: I-WD8116 isetyenziswe ngokubanzi kwaye ikhulile kwi-NY / RCPP kwi-121° C;
Isakhiwo seplastiki ye-aluminium: Ukusetyenziswa kwe-WD8262 kwi-AL / RCPP kwi-121° U-C naye uqole kakhulu.
Kwangaxeshanye, ekuphekeni nasekufakeni inzala kwisakhiwo se-aluminium-plastiki, i-medium (ethyl maltol) ukunyamezela ukusebenza kwe-WD8262 nayo ilungile.
2.Isikhokelo soPhuhliso lwexesha elizayo lokupheka kobushushu obuphezulu
Ukongeza kwizinto eziqhelekileyo ezintathu - kunye nezakhiwo ezine zomaleko, izinto eziphambili ezisetyenzisiweyo yi-PET, AL, NY, kunye ne-RCPP.Nangona kunjalo, ezinye izinto ziye zaqaliswa ukusetyenziswa kwiimveliso zokupheka kwimarike, ezifana nokwaleka kwe-aluminium ecacileyo, ifilimu yokupheka yokushisa ephezulu ye-polyethylene, njl. isiseko sesicelo sabo esixhaphakileyo sisafuna ukuvavanywa ixesha elide kunye neenkqubo ezininzi.Ngokomgaqo, i-adhesives e-solvent-free i-adhesives nayo ingasetyenziswa, kwaye umphumo wangempela ukwamkelekile ukuba uqinisekiswe kwaye uvavanywe ngamashishini okushicilela umbala.
Ukongeza, i-adhesives-free adhesives nayo iphucula ukusebenza kwayo ngokumalunga nobushushu bokwenza inzala.Okwangoku, kuye kwenziwa inkqubela phambili ebalulekileyo ekuqinisekisweni kokusebenza kweemveliso ze-Konda New Materials ezinganyibilikiyo phantsi kweemeko ze-125.° C kunye ne-128° C, kwaye kwenziwa iinzame zokufikelela encotsheni yokupheka yobushushu obuphezulu, njenge-135° C ukupheka kunye nokuba 145° C ukupheka.
3.Amanqaku aphambili osetyenziso kunye nolawulo lwenkqubo
3.1Ukusekwa kunye nokuqinisekiswa kwexabiso lokunamathela
Kule mihla, ukuthandwa kwezixhobo ezinganyibilikiyo kuyanda, kwaye abavelisi abaninzi baye bafumana amava angakumbi kunye nokuqonda ekusebenziseni izixhobo ezingenazinyibilikisi.Nangona kunjalo, inkqubo yokupheka inzalo yobushushu obuphezulu isafuna umlinganiselo othile we-adhesive interlayer (okt ubukhulu), kunye nexabiso lokuncamathelisa kwiinkqubo eziqhelekileyo akwanelanga ukuhlangabezana neemfuno zokupheka inzala.Ngoko ke, xa usebenzisa i-adhesive-free adhesive kwi-package yokupheka edibeneyo, inani le-adhesive efakwe kufuneka linyuswe, kunye noluhlu olucetyiswayo lwe-1.8-2.5g / m.².
3.2 Uluhlu lokufuma kokusingqongileyo
Kule mihla, abavelisi abaninzi baqala ukuqonda kwaye bancamathisele ukubaluleka kwimpembelelo yezinto ezisingqongileyo kumgangatho wemveliso.Emva kokuqinisekiswa kunye nesishwankathelo samatyala amaninzi asebenzayo, kuyacetyiswa ukuba kulawulwe ukufuma kokusingqongileyo phakathi kwe-40% kunye ne-70%.Ukuba umswakama uphantsi kakhulu, kufuneka ufumiswe, kwaye ukuba umswakama uphezulu kakhulu, kufuneka uhlanjululwe.Ngenxa yokuba inxalenye yamanzi kwimekobume ithatha inxaxheba ekuphenduleni iglue ye-solvent-free, Nangona kunjalo, ukuthatha inxaxheba kwamanzi amaninzi kunokunciphisa ubunzima be-molecular yeglue kwaye kubangele ukusabela kwecala elithile, ngaloo ndlela kuchaphazela ukusebenza kobushushu obuphezulu ngexesha lokupheka.Ngoko ke, kuyimfuneko ukulungelelanisa ukucwangciswa kwamacandelo e-A / B kancinane kwiqondo lokushisa eliphezulu kunye neendawo zokufuma.
3.3 Useto lweparamitha yokusebenza kwesixhobo
Useto lweParameter lusetwa ngokweemodeli zesixhobo ezahlukeneyo kunye noqwalaselo;Ukumiselwa koxinzelelo kunye nokuchaneka komlinganiselo wokukhupha zizo zonke iinkcukacha zolawulo kunye nokuqinisekiswa.Inqanaba eliphezulu lokuzenzekela, ukuchaneka, kunye nokusebenza ngokulula kwezixhobo ezingenazinyibilikisi ziinzuzo zayo, kodwa ikwagubungela ukubaluleka kokucokiseka kunye nokulumka emva kwayo.Besisoloko sigxininisa ukuba imisebenzi yokuvelisa i-solvent free yinkqubo ecokisekileyo.
3.4 Iimfuno zemathiriyeli ekrwada
Ukuba tyaba okuhle, ukumanzi komphezulu, izinga lokucutheka, kunye nomxholo wokufuma wefilimi ebhityileyo yemathiriyeli ekrwada ziimeko eziyimfuneko zokugqiba ukuphekwa kwezinto ezixutyiweyo.
- Iingenelo ze-solvent-free composites
Okwangoku, ukupheka okunobushushu obuphezulu kunye neemveliso zokucoca kwishishini ikakhulu zisebenzisa i-adhesives esekelwe kwi-solvent yokudibanisa okomileyo.Xa kuthelekiswa ne-composite eyomileyo, ukusebenzisa iimveliso zokupheka ezixutywe ne-solvent-free kunezi nzuzo zilandelayo:
4.1iinzuzo zokusebenza kakuhle
Inzuzo yokusebenzisa i-adhesives-free adhesives ngokuyinhloko ukwanda kwamandla okuvelisa.Njengoko kusaziwa, ukusebenzisa itekhnoloji eyomileyo yokudibanisa ukupheka ubushushu obuphezulu kunye nemathiriyeli yokuvala inzala inesantya esisezantsi semveliso, esijikeleze i-100m/min.Ezinye iimeko zezixhobo kunye nokulawulwa kwemveliso zilungile, kwaye zinokufikelela kwi-120-130m / min.Nangona kunjalo, iimeko azifanelekanga, kuphela i-80-90m / min okanye nangaphantsi.Umthamo osisiseko wokukhupha i-adhesives-free adhesives kunye nezixhobo ezidibeneyo zingcono kunezo zidibeneyo ezomileyo, kwaye isantya esidibeneyo sinokufikelela kwi-200m / min.
4.2inzuzo yeendleko
Ubungakanani beglue efakwe kwiglue yokupheka esekelwe kwi-solvent esekelwe kubushushu obuphezulu bukhulu, ilawulwa ngokusisiseko kwi-4.0g/m.² Ekhohlo nasekunene, umda awukho ngaphantsi kwe-3.5g/m²Nokuba isixa seglue esisetyenziswe kwiglue yokupheka engena-solvent yi-2.5g/m² Xa kuthelekiswa neendlela ezisekelwe kwi-solvent, nayo inenzuzo enkulu yeendleko ngenxa yomxholo wokunamathela ophezulu.
4.3Izinto eziluncedo kukhuseleko kunye nokukhuselwa kwendalo
Ngethuba lokusetyenziswa kwe-solvent esekelwe kwi-high-temperature yokupheka iglue, inani elikhulu le-ethyl acetate kufuneka lifakwe kwi-dilution, eyonakalisa ukukhuselwa kwendalo kunye nokhuseleko lweworkshop yokuvelisa.Ikwaqhelekile kwingxaki yentsalela ye-solvent ephezulu.Kwaye izinto zokuncamathelisa ezingenazinyibilikisi azinangxaki enjalo konke konke.
4.4Iinzuzo zokonga amandla
Umlinganiselo wokuphilisa we-solvent based adhesive composite products uphezulu, ngokusisiseko kuma-50° C okanye ngaphezulu;Ixesha lokuvuthwa kufuneka libe ziiyure ezingama-72 okanye ngaphezulu.Isantya sokuphendula seglue yokupheka enganyibilikiyo ikhawuleza kakhulu, kwaye imfuno yokunyanga ubushushu kunye nexesha lokunyanga liya kuba sezantsi.Ngokuqhelekileyo, iqondo lokushisa liyi-35° C ~ 48° C, kwaye ixesha lokunyanga liyi-24-48 iiyure, ezinokunceda ngokufanelekileyo abathengi banciphise umjikelo.
5.Isiphelo
Isishwankathelo, i-adhesives-free adhesives, ngenxa yeempawu zabo ezizodwa, amashishini oshicilelo lwemibala, amashishini ancamathelayo, kunye ne-solvent-free-free composite izixhobo zokuvelisa izixhobo ziye zasebenzisana kwaye zaxhasana iminyaka emininzi, zibonelela ngamava abalulekileyo kunye nolwazi kwiinkalo zabo.Sikholelwa ukuba i-adhesives-free adhesives inoluhlu olubanzi lwezicelo kwixesha elizayo.Ifilosofi yophuhliso ye-Kangda New Materials "sisebenza nzima ukwenza ixabiso kubathengi kwaye sibahambise".Siyathemba ukuba iimveliso zethu zokupheka ezinobushushu obuphezulu zinokunceda amashishini amaninzi oshicilelo lombala aphonononge imimandla emitsha yesicelo ehlanganisiweyo enganyibilikiyo.
