Izinto ezincamathelayo zizinto ezidibanisa umphezulu odibanayo wemathiriyeli kunye.I-Adhesives inokwahlulwa ibe yi-adhesives, i-binders, i-adhesive bonding agents, abagqugquzeli bokubambelela, i-tackifiers kunye ne-adhesives impregnating, njl., ngokweendlela ezahlukeneyo zokudibanisa kunye neenkqubo zokusebenza.
I-Tackifier: ibhekisa kwizinto ezinokonyusa i-viscosity yezinto ezincamathelayo ezingavuzwanga, ezifana ne-petroleum resin, i-coumarone resin, i-styrene indene resin, i-p-alkylphenol formaldehyde resin engasetyenziswanga thermal kunye nepine tar.Ukubambelela kubhekisela kumandla okanye umsebenzi ofunekayo ukukrazula iifilimu ezimbini ze-homogeneous emva komthwalo omncinci kunye ne-lamination yexesha elifutshane, oko kukuthi, ukuzibamba.I-tackifier yandisa kuphela i-viscosity yendawo yezinto zerabha ngexesha lokusetyenzwa kweemveliso zerabha ezininzi, eziququzelela inkqubo yokudibanisa phakathi kweeleya zerabha.Ikakhulu iphucula isiphumo se-bonding ngokwandisa i-adsorption yomzimba, kwaye iyinxalenye yoluhlu lwezinto zokuncedisa.
Impregnation incamathiso: ekwaziwa ngokuba yincamathelisi engathanga ngqo, ibhekisa kulwelo lokufakelwa oluqulathe amacandelo e-viscous agquma umphezulu welaphu lefayibha okanye ukungena kumsantsa ongaphakathi welaphu ngenkqubo yokufakwa.Ilaphu lidityaniswe ngamachiza, kwaye olu lwazi lufakelwayo lubizwa ngokuba yi-adhesive impregnating, njenge-tritu-component NaOH emulsion bonding system ye-resorcinol, i-formaldehyde kunye ne-latex, okanye inkqubo ye-RFL, eyona nto iphucula i-bonding effect ye-rubber kunye ne-fiber.enye yeendlela eziphambili.Kwimicu eyahlukeneyo, ukubunjwa kwe-liquid impregnating iyahluka.Ngokomzekelo, i-latex (i-L component) ingaba yi-NRL okanye i-butyl pyridine latex, kwaye inani le-resorcinol kunye ne-formaldehyde nalo lingatshintshwa.Kwimicu enzima ukudibanisa njenge-polyester, i-aramid kunye ne-glass fiber, ngaphezu kokubunjwa kwe-RFL, ezinye izithako ezihambelana nokudibanisa kufuneka zongezwe, ezifana ne-isocyanate, i-agent yokudibanisa i-silane, njl.
I-ejenti ye-Bonding: Eyaziwa ngokuba yi-adhesive ngqo, ixutywe kwikhompawundi ngexesha lokuxuba, kwaye ngexesha le-vulcanization, i-chemical bonding okanye i-adsorption eyomeleleyo ye-substance adsorption yenzeke phakathi kwemiphezulu ukuba ibambelele ukwenza into ebophelelwe ngokuqinileyo, njenge-interlayer eqhelekileyo.I-Hydroquinone donor-methylene donor-silica bonding system (i-m-methyl emhlophe inkqubo, inkqubo ye-HRH), inkqubo yokudibanisa i-triazine.Kulo hlobo lwe-adhesive, akukho luhlu oluphakathi olusekelwe kwi-adhesive ebusweni bezinto ezimbini apho ibhondi iveliswa khona.Olu ncamatheliso lusetyenziswa kakhulu ukwenza iqhina elomeleleyo nelomeleleyo phakathi kwerubha kunye nemathiriyeli yamathambo.
Isibophelelo (isincamathelisi): sibhekisa kwinto encamathela kumgubo oyekayo okanye imathiriyeli eneentsinga kunye ukuze zenze into epheleleyo eqhubekayo, enjengephepha lokubopha intlama, isibophelelo esingalukwanga, isibophelelo seasbestos, umgubo. izinto ezilulwelo, kunye ne-binder kunye nomgubo zixutywe ngokulinganayo ngesantya esiphezulu sokuzamisa kunye nezinye iindlela, kwaye isibophelelo sibonelela ngamandla adibeneyo wokudibanisa.
I-Adhesivepromotingagen: ibhekiselele kwizinto zekhemikhali ezivelisa ngokuthe ngqo i-adsorption yomzimba okanye i-chemical bonding phakathi kwezixhobo, kodwa inokukhuthaza ukwenzeka kokunamathela, njengokuncamathisela kwerabha kunye nesinyithi esifakwe ngobhedu.Ityuwa ye-cobalt ye-organic esetyenziswe kwinkqubo ngumgqugquzeli wokubambelela.Lo mgqugquzeli wokubambelela wongezwa ngokuthe ngqo kwi-compound njenge-agent edibeneyo kwaye udlala indima kwi-vulcanization yokushisa okuphezulu.
I-Adhesive (i-adhesive): ibhekisela kwiklasi yezinto ezidibanisa iindawo ezimbini okanye ngaphezulu (okanye izinto) kunye, ubukhulu becala ngendlela yeglue okanye i-adhesive tape, kunye nokufezekisa ukubambelela ngokutshiza, ukugubungela kunye neenkqubo zokunamathela.Injongo.Le ndlela yokudibanisa kukwenza umaleko wokudibanisa ophakathi kunye ne-adhesive njengeyona nxalenye ephambili phakathi kwemiphezulu yezinto ezimbini, ezifana nokudibanisa phakathi kwerabha edibeneyo, ukudibanisa phakathi kwerabha ehlanjululweyo kunye nesikhumba, iinkuni kunye nentsimbi.I-Adhesive Iipropati zayo kunye nokusebenza, kunye nenkqubo yokudibanisa inquma umphumo wokudibanisa.
Phakathi kwezincamathelisi ezikhankanywe ngasentla, i-adhesive enesicelo esibanzi, i-dosage enkulu kunye nenkqubo yokusebenza elula yi-adhesive.Kukho iintlobo ezininzi zokuncamathelisa, kwaye ukusebenza kwazo kwahlukile.Ukukhetha uhlobo olufanelekileyo kunokufumana amandla aphezulu okudibanisa.Ngoko ke, i-adhesives iphuhliswe ngokukhawuleza kwaye ibe yinto esetyenziswa ngokuqhelekileyo kwinkqubo yokudibanisa.
Okwangoku, i-adhesives esetyenziswa ngokuqhelekileyo yi-isocyanate adhesives, i-halogen-containing adhesives kunye ne-phenolic resin adhesives.I-adhesive yayo ye-isocyanate i-adhesive efanelekileyo yerabha kunye neentsimbi ezahlukeneyo.Ibonakaliswe ngamandla amakhulu okubopha, ukuxhathisa ukothuka okugqwesileyo, inkqubo elula, ukuxhathisa kwe-oyile, ukuxhathisa kwe-solvent, ukumelana nolwelo lwamafutha, ukuxhathisa kwe-asidi kunye ne-alkali kunye nezinye iipropathi, kodwa ukuxhathisa ubushushu kuncinci..I-rubber ye-Hydrochlorinated yimveliso efunyenwe ngokusabela kwerubha yendalo kunye ne-hydrogen chloride, enozinzo oluhle lweekhemikhali kwaye ayitshisi.I-adhesives yerubha eneklorini ene-adhesion efanelekileyo inokufumaneka ngokunyibilikisa irabha eklorini kwi-arhente efanelekileyo.I-adhesives ye-rubber ye-chlorine isetyenziselwa kakhulu irabha ye-polar (i-rubber ye-neoprene kunye ne-rubber nitrile, njl.) kunye nesinyithi (intsimbi, i-aluminium, Inokusetyenziswa njengengubo yokukhusela indawo ngenxa yokuxhathisa kwamanzi kunye nokuxhathisa kwamanzi olwandle.
