Inkcazo: Eli nqaku lihlalutya ukusebenza, unxulumano, kunye nendima yokuncamathelisa kwinqanaba lokuncamathela kwizigaba ezahlukeneyo zokudityaniswa, nto leyo esinceda ukuba sigwebe ngcono oyena nobangela weengxaki zenkangeleko edibeneyo kwaye sisombulule ingxaki ngokukhawuleza.
Kwinkqubo yokupakishwa okuguquguqukayo kwemveliso edibeneyo, "inqanaba" lokubambelela kunempembelelo enkulu kumgangatho odibeneyo.Nangona kunjalo, inkcazo ye "leveling", izigaba ezahlukeneyo "zomgangatho", kunye nefuthe lamazwe amancinci kumgangatho wokugqibela odibeneyo awucaci kakuhle.Eli nqaku lithatha i-adhesive ye-solvent njengomzekelo wokuxoxa ngentsingiselo, ukulungelelaniswa, kunye nendima yokulinganisa kwizigaba ezahlukeneyo.
1.Intsingiselo yokulinganisa
Iipropathi zomgangatho wokuncamathelisa: Ukuqukuqela okuthambileyo isakhono sokuncamathelisa kwasekuqaleni.
Umgangatho wolwelo olusebenzayo: Emva kokuhlanjululwa, ukufudumeza kunye nezinye iindlela zokungenelela, ukukwazi kwe-adhesive working fluid ukuhamba kunye nokunciphisa ngexesha lemisebenzi yokugubungela kufezekiswa.
Ikhono lokuqala lokulinganisa: Ikhono lokulinganisa le-adhesive emva kokugquma kunye naphambi kokulala.
Ikhono lesibini lokulinganisa: Ukukwazi kwe-adhesive ukuba ihambe kwaye ibe mcaba emva kokudibanisa ide ikhule.
2.Unxulumano kunye nefuthe lokulinganisa kumanqanaba ahlukeneyo
Ngenxa yezinto zokuvelisa ezifana nexabiso lokuncamathelisa, imeko yokwambathisa, imeko yokusingqongileyo (iqondo lobushushu, ukufuma), i-substrate state (uxinzelelo lomphezulu, ukucaba), njl njl., isiphumo sokugqibela sokudibanisa sinokuchaphazeleka.Ngaphezu koko, izinto ezininzi eziguquguqukayo zezi zinto zinokubangela ukuguquguquka okubalulekileyo kwisiphumo sembonakalo edibeneyo kwaye kubangele inkangeleko enganelisiyo, engenakubalelwa nje kukungaphakami kakuhle kokuncamathelisa.
Ngoko ke, xa sixubusha impembelelo yomgangatho kumgangatho odibeneyo, siqala sicinga ukuba izikhombisi zemiba yokuvelisa ingentla zihambelana, oko kukuthi, ukungabandakanyi impembelelo yale miba ingentla kwaye sixoxe nje ngokulinganayo.
Okokuqala, makhe silungise ubudlelwane phakathi kwabo:
Kwi-fluid esebenzayo, umxholo we-solvent uphezulu kune-adhesive ecocekileyo, ngoko i-viscosity ye-adhesive iyona nto iphantsi phakathi kwezi zikhombisi zingentla.Ngexesha elifanayo, ngenxa yokuxuba okuphezulu kwe-adhesive kunye ne-solvent, ukunyanzeliswa kwayo kwendawo kuphantsi kakhulu.Ukuhamba kwe-adhesive working fluid iyona nto ibhetele phakathi kwezi zikhombisi zingentla.
Umgangatho wokuqala kuxa ubumanzi bolwelo olusebenzayo buqala ukuhla ngenkqubo yokomisa emva kokugquma.Ngokubanzi, indawo yokugweba yenqanaba lokuqala isemva kokujija okudityanisiweyo.Ngokunyuka ngokukhawuleza kwe-solvent, i-fluidity eziswa yi-solvent ilahleka ngokukhawuleza, kwaye i-viscosity ye-adhesive isondele kwi-adhesive ecocekileyo.Ukulinganiswa kwerabha ekrwada kubhekiselele kumanzi okuncamathelisa ngokwawo xa isinyibilikisi esiqulethwe kwirabha ekrwada yomphanda sikhutshiwe naso.Kodwa ubude beli nqanaba bufutshane kakhulu, kwaye njengoko inkqubo yokuvelisa iqhubeka, iya kungena ngokukhawuleza kwinqanaba lesibini.
Inqanaba lesibini libhekisa ekungeneni kwinqanaba lokuvuthwa emva kokuba inkqubo ehlanganisiweyo igqityiwe.Ngaphantsi kwefuthe lobushushu, i-adhesive ingena kwinqanaba lokuphendula ngokukhawuleza kwe-crosslinking, kwaye i-fluidity yayo iyancipha ngokunyuka kweqondo lokuphendula, ekugqibeleni ilahlekelwe ngokupheleleyo.Isiphelo: Ukulinganisa ulwelo olusebenzayo ≥ umgangatho wokuqala> ukulinganisa i-gel yokuqala> ukulinganisa okwesibini
Ngoko ke, ngokubanzi, ubungakanani bemali kwezi zigaba zine zingasentla buyehla kancinci ukusuka phezulu ukuya phantsi.
I-3.Impembelelo kunye namanqaku okulawula izinto ezahlukeneyo kwinkqubo yokuvelisa
3.1 Isixa sesicelo seGlue
Isixa seglue esisetyenzisiweyo asidingeki ukuba sinxibelelene nolwelo lweglu.Kumsebenzi odityanisiweyo, inani eliphezulu lokuncamathelisa libonelela ngokuncamathelisa ngakumbi kwi-interface edibeneyo ukuhlangabezana nemfuno yojongano lobungakanani bokuncamathelisa.
Ngokomzekelo, kwi-rough bonding surface, i-adhesive yongeza izikhewu ze-interlayer ezibangelwa yi-interlayer engalinganiyo, kwaye ubungakanani bezithuba bunquma inani leengubo.I-fluidity ye-adhesive inquma kuphela ixesha elithathayo ukuzalisa izikhewu, kungekhona iqondo.Ngamanye amazwi, nokuba i-adhesive ine-fluidity enhle, ukuba isixa sokugquma siphantsi kakhulu, kuya kubakho izinto ezifana "namabala amhlophe, amaqamza".
3.2Isimo sokugquma
Umbuso wokugcoba unqunywe ngokusasazwa kwe-adhesive edluliselwe yi-coating net roller kwi-substrate.Ngoko ke, phantsi kwesixa esifanayo sokugquma, i-mesh ye-mesh ye-coating roller iyancipha, ifutshane ukuhamba phakathi kwamanqaku okunamathela emva kokudluliselwa, ngokukhawuleza ukubunjwa kwe-adhesive layer, kunye nokubonakala ngcono.Njengomsebenzi wamandla wangaphandle ophazamisa uxhulumaniso lwe-adhesive, ukusetyenziswa kwee-rollers zeglue ezifanayo kunempembelelo ebaluleke kakhulu kwimbonakalo edibeneyo kunezo zingasetyenziswanga.
3.3Imeko
Amaqondo okushisa ahlukeneyo amisela i-viscosity yokuqala ye-adhesive ngexesha lemveliso, kwaye i-viscosity yokuqala inquma ukuhamba kokuqala.Ukuphakama kweqondo lokushisa, i-viscosity ephantsi ye-adhesive, kwaye ingcono ukuhamba.Nangona kunjalo, njengoko i-solvent iguquka ngokukhawuleza, ukuxinwa kwesisombululo sokusebenza kutshintsha ngokukhawuleza.Ngoko ke, phantsi kweemeko zokushisa, izinga lokunyuka kwe-solvent lihambelana ngokuphambene ne-viscosity yesisombululo sokusebenza.Kwimveliso egqithisileyo, ukulawula izinga lokunyuka komphunga we-solvent ibe ngumba obaluleke kakhulu.Umswakama kwindawo uya kukhawulezisa izinga lokusabela kwe-adhesive, ukwandisa ukwanda kwe-viscosity ye-adhesive.
4.Isiphelo
Kwinkqubo yokuvelisa, ukuqonda okucacileyo kokusebenza, ukulungelelaniswa, kunye nendima "ye-adhesive leveling" kumanqanaba ahlukeneyo kunokusinceda ukuba siqonde kakuhle isizathu esiyinyaniso seengxaki zokubonakala kwizinto ezidibeneyo, kwaye sichonge ngokukhawuleza iimpawu zengxaki kwaye sizisombulule. .
