Isishwankathelo: Eli nqaku lihlalutya ukusebenza, ulwalamano, kunye nendima yokulinganisa i-adhesive kumanqanaba ahlukeneyo okudibanisa, oku kusinceda sigwebe ngcono unobangela wokwenene weengxaki zokubonakala kwe-compound kwaye sisombulule ingxaki ngokukhawuleza.
Kwinkqubo yokuvelisa i-composite packaging eguquguqukayo, "ukulinganisa" kwe-adhesive kunempembelelo enkulu kumgangatho we-composite. Nangona kunjalo, inkcazo "yokulinganisa", amanqanaba ahlukeneyo "okulinganisa", kunye nempembelelo ye-microscopic states kumgangatho wokugqibela we-composite ayicacanga kakuhle. Eli nqaku lithatha i-solvent adhesive njengomzekelo ukuxoxa ngentsingiselo, ulwalamano, kunye nendima ye-leveling kumanqanaba ahlukeneyo.
1. Intsingiselo yokulinganisa
Iimpawu zokulinganisa izincamathelisi: Amandla okuthamba okuhamba kwesisincamathelisi sokuqala.
Ukulinganiswa kolwelo olusebenzayo: Emva kokuxutywa, ukufudumeza kunye nezinye iindlela zokungenelela, amandla olwelo olusebenzayo olunamathelayo lokuhamba nokuthamba ngexesha lemisebenzi yokugquma ayafezekiswa.
Amandla okulinganisa kokuqala: Amandla okulinganisa iglu emva kokugquma nangaphambi kokugquma.
Amandla okwesibini okulinganisa: Amandla okunamathela okuhamba nokuthamba emva kokudibanisa ide ikhule.
2. Ubudlelwane kunye neziphumo zokulinganisa kwinqanaba kumanqanaba ahlukeneyo
Ngenxa yezinto zemveliso ezifana nobungakanani beglu, imeko yokugquma, imeko yokusingqongileyo (ubushushu, ukufuma), imeko ye-substrate (uxinzelelo lomphezulu, ukuthamba), njl.njl., isiphumo sokugqibela seglue sinokuchaphazeleka. Ngaphezu koko, izinto ezininzi eziguquguqukayo zezi zinto zinokubangela ukuguquguquka okukhulu kwisiphumo seglue kwaye zibangele ukubonakala okungenanelisiyo, okungenakubangelwa nje kukungalingani kakuhle kweglue.
Ngoko ke, xa sixoxa ngempembelelo yokulinganisa umgangatho odibeneyo, siqala ngokucinga ukuba izalathisi zezinto eziveliswa ngasentla ziyahambelana, oko kukuthi, azibandakanyi impembelelo yezinto eziveliswa ngasentla kwaye sixoxe nje ngokulinganisa.
Okokuqala, makhe sijonge ubudlelwane phakathi kwabo:
Kwi-fluid esebenzayo, umxholo we-solvent uphezulu kunowe-glue ecocekileyo, ngoko ke i-viscosity ye-glue yeyona iphantsi phakathi kwezibonisi ezingentla. Kwangaxeshanye, ngenxa yokuxubana okuphezulu kwe-glue kunye ne-solvent, uxinzelelo lomphezulu wayo nalo luphantsi. Ukuhamba kolwelo olusebenzayo lwe-glue yeyona ilungileyo phakathi kwezibonisi ezingentla.
Ukulinganisa kokuqala kuxa ukuguquguquka kolwelo olusebenzayo kuqala ukwehla ngenkqubo yokomisa emva kokugquma. Ngokubanzi, i-node yokugweba yokulinganisa kokuqala isemva kokujija okuhlanganisiweyo. Xa i-solvent iphuma ngokukhawuleza, ukuguquguquka okuziswa yi-solvent kulahleka ngokukhawuleza, kwaye i-viscosity ye-glue isondele kweyokunamathela okucocekileyo. Ukulinganisa i-raber eluhlaza kubhekisa kukuguquguquka kwe-glue ngokwayo xa i-solvent ekwi-raber eluhlaza egqityiweyo nayo isuswa. Kodwa ixesha leli nqanaba lifutshane kakhulu, kwaye njengoko inkqubo yemveliso iqhubeka, iya kungena ngokukhawuleza kwinqanaba lesibini.
Ukulinganisa okwesibini kubhekisa ekungeneni kwinqanaba lokuvuthwa emva kokuba inkqubo yokudibanisa igqityiwe. Phantsi kwempembelelo yobushushu, i-adhesive ingena kwinqanaba le-reaction ekhawulezayo yokudibanisa, kwaye ukugeleza kwayo kwehla ngokwanda kwenqanaba lokuphendula, ekugqibeleni ilahleka ngokupheleleyo. Isiphelo: Ukulinganisa ulwelo olusebenzayo ≥ ukulinganisa kokuqala> ukulinganisa kwejeli yokuqala> ukulinganisa okwesibini
Ngoko ke, ngokubanzi, ukuguquguquka kwala manqanaba mane angentla kwehla kancinci kancinci ukusuka phezulu ukuya ezantsi.
3.Impembelelo kunye namanqaku olawulo lwezinto ezahlukeneyo kwinkqubo yemveliso
3.1 Isixa sesicelo seglue
Ubungakanani beglu esetyenzisiweyo abuxhomekekanga ekuguquguqukeni kweglu. Kumsebenzi wokudibanisa, inani eliphezulu leglue libonelela ngeglue engaphezulu kwi-composite interface ukuhlangabezana neemfuno ze-interface zobungakanani beglue.
Umzekelo, kumphezulu oqinileyo wokubopha, i-adhesive yongeza izithuba eziphakathi kwe-interlayer ezibangelwa zii-interfaces ezingalinganiyo, kwaye ubungakanani bezithuba bumisela ubungakanani be-coating. Ukutyibilika kwe-adhesive kumisela kuphela ixesha elithathayo ukuzalisa izithuba, hayi ubungakanani. Ngamanye amazwi, nokuba i-adhesive inokuguquguquka okuhle, ukuba ubungakanani be-coating buphantsi kakhulu, kuya kubakho izinto ezifana "namabala amhlophe, amaqamza".
3.2Imeko yokwaleka
Imeko yokugquma imiselwa kukusasazwa kweglue edluliselwe yirola enetha yokugquma kwi-substrate. Ke ngoko, phantsi kobungakanani obufanayo bokugquma, kokukhona udonga lwe-mesh lwerola yokugquma luncipha, kokukhona ukuhamba phakathi kwamanqaku okugquma emva kokudluliselwa, kokukhona ukwakheka kweglue kukhawulezisa, kwaye kokukhona ukubonakala kungcono. Njengento yamandla angaphandle ephazamisa uqhagamshelo lweglue, ukusetyenziswa kwee-rollers zeglue ezifanayo kunempembelelo entle ebalulekileyo kwimbonakalo edibeneyo kunezo zingasetyenziswanga.
3.3 Imeko
Amaqondo obushushu ahlukeneyo amisela ubungqindilili bokuqala beglu ngexesha lokuveliswa, kwaye ubungqindilili bokuqala bumisela ubungqindilili bokuqala. Okukhona ubushushu buphezulu, ubungqindilili beglu buphantsi, kwaye kokukhona ubungqindilili obuhle. Nangona kunjalo, njengoko isinyibilikisi sitshintsha ngokukhawuleza, uxinzelelo lwesisombululo esisebenzayo lutshintsha ngokukhawuleza. Ke ngoko, phantsi kweemeko zobushushu, izinga lokuphuma kweglu lihambelana ngokuphambeneyo nobungqindilili besisombululo esisebenzayo. Kwimveliso egqithisileyo, ukulawula izinga lokuphuma kweglu kube yingxaki ebaluleke kakhulu. Ukufuma kwindalo esingqongileyo kuya kukhawulezisa izinga lokusabela kweglu, okwandisa ukwanda kobungqindilili beglu.
4. Isiphelo
Kwinkqubo yemveliso, ukuqonda ngokucacileyo ukusebenza, ulwalamano, kunye nendima "yokulinganisa okunamathelayo" kumanqanaba ahlukeneyo kunokusinceda siqonde ngcono unobangela wokwenene weengxaki zokubonakala kwezinto ezidityanisiweyo, kwaye sikhawuleze sichonge iimpawu zengxaki size sizisombulule.
