Izinamatheliso yizinto ezihlanganisa izindawo eziseduze zento eyodwa.Izinto zokunamathisela zingahlukaniswa zibe izinamathiselo, izibophezelo, ama-adhesive bonding agents, abagqugquzeli bokunamathela, ama-tackifiers nama-adhesive afakayo, njll, ngokusho kwezinqubo ezahlukene zokubopha kanye nezinqubo zokusebenza.
I-Tackifier: ibhekisela ezintweni ezingakhuphula i-viscosity yezinto ezinamathelayo ezingavuthisiwe, njenge-petroleum resin, i-coumarone resin, i-styrene indene resin, i-p-alkylphenol formaldehyde resin engashisi ngokushisa kanye nethayela likaphayini.I-Adhesion ibhekisela kumandla noma umsebenzi odingekayo ukuze kukhishwe amafilimu amabili afanayo ngemuva komthwalo omncane kanye ne-lamination yesikhashana, okungukuthi, ukuzibamba.I-tackifier inyusa kuphela i-viscosity yangaphezulu yezinto zenjoloba ngesikhathi sokucutshungulwa kwemikhiqizo yerabha enezingqimba eziningi, okusiza inqubo yokubopha phakathi kwezingqimba zenjoloba.Ngokuyinhloko ithuthukisa umphumela wokubopha ngokwandisa ukukhangiswa ngokomzimba, futhi ingeyesigaba sezinsiza zokucubungula.
I-Impregnation Adhesive: eyaziwa nangokuthi i-adhesive engaqondile, ibhekisela oketshezini lokufakelwa oluqukethe izingxenye ze-viscous ezimboza ubuso bendwangu ye-fiber noma olungena esikhaleni sangaphakathi sendwangu ngenqubo yokufaka.Indwangu ihlanganiswe ngamakhemikhali, futhi lolu ketshezi olukhulelwe lubizwa ngokuthi i-adhesive impregnating, njenge-NaOH emulsion bonding system enezingxenye ezintathu ze-resorcinol, i-formaldehyde ne-latex, noma uhlelo lwe-RFL, okuwukuthuthukisa umphumela wokubopha werabha ne-fiber.enye yezindlela eziyinhloko.Ngemicu ehlukene, ukwakheka koketshezi olufakayo kuhlukile.Isibonelo, i-latex (ingxenye ye-L) ingaba yi-NRL noma i-butyl pyridine latex, futhi inani le-resorcinol ne-formaldehyde lingashintshwa.Kumafayili okunzima ukuwahlanganisa njenge-polyester, i-aramid ne-glass fiber, ngaphezu kokwakheka kwe-RFL, ezinye izithako ezihambisana nokubopha kufanele zengezwe, njenge-isocyanate, i-agent yokuhlanganisa i-silane, njll.
I-ejenti yebhondi: Eyaziwa nangokuthi i-adhesive eqondile, ixutshwa kwinhlanganisela ngesikhathi sokuxutshwa, futhi ngesikhathi sokuvuthwa, ukuhlangana kwamakhemikhali noma ukukhangisa kwento eqinile kwenzeka phakathi kwezindawo okumele zinamathele ukuze kwakhe into ebophene ngokuqinile, njenge-interlayer evamile.I-Hydroquinone donor-methylene donor-silica bonding system (isistimu ye-m-methyl emhlophe, isistimu ye-HRH), isistimu yokubopha i-triazine.Kulolu hlobo lwe-adhesive, akukho ungqimba oluphakathi olusekelwe ekunamatheleni ezindaweni ezimbili zezinto lapho isibopho sikhiqizwa khona.Le nto yokunamathisela isetshenziswa kakhulu ukwakha isibopho esiqinile nesihlala isikhathi eside phakathi kwezinto zenjoloba nohlaka lwamathambo.
I-Binder (i-adhesive): ibhekisela entweni enamathela empushaneni engaqhubeki noma izinto ezixubene ukuze zenze konke okuqhubekayo, njenge-paper pulp binder, i-non-woven binder, i-asbestos binder, powder izinto eziwuketshezi, kanye ne-binder kanye nempushana kuxutshwa ngokulinganayo ukunyakaziswa kwesivinini esikhulu nezinye izindlela, futhi isibopho sinikeza amandla ahlangene okuhlanganisa.
I-Adhesivepromotingagen: isho into yamakhemikhali ekhiqiza ngokuqondile i-adsorption ebonakalayo noma isibopho samakhemikhali phakathi kwezinto, kodwa engakhuthaza ukuvela kokunamathela, njengokunamathela kwerabha nensimbi egqitshwe ngethusi.Usawoti we-organic cobalt osetshenziswe kule nqubo ungumgqugquzeli wokunamathela.Lo mgqugquzeli wokunamathela ubuye wengezwe ngokuqondile ku-compound njenge-ejenti ehlanganisayo futhi udlala indima enqubweni yokushisa ephezulu ye-vulcanization.
I-Adhesive (i-adhesive): ibhekisela ekilasini lezinto ezixhuma izingxenye ezimbili noma ngaphezulu (noma izinto zokwakha) ndawonye, ikakhulukazi ngendlela yeglue noma i-adhesive tape, futhi ifinyelele ukunamathela ngokufafaza, ukunamathela kanye nezinqubo zokunamathela.Inhloso.Le ndlela yokuhlanganisa iwukwenza ungqimba oluyisibopho olumaphakathi olunamatheliswayo njengengxenye eyinhloko phakathi kwezindawo ezimbili zezinto ezisetshenziswayo, njengokubopha phakathi kwenjoloba eshibhile, isibopho phakathi kwenjoloba eshisiwe nesikhumba, ukhuni nensimbi.I-Adhesive Izakhiwo zayo nokusebenza kwayo, futhi inqubo yokubopha inquma umphumela wokubopha.
Phakathi kwezinamatheliso ezibalulwe ngenhla, i-adhesive enesicelo esibanzi, umthamo omkhulu kanye nenqubo yokusebenza elula yi-adhesive.Kunezinhlobo eziningi zokunamathisela, futhi ukusebenza kwazo kuhlukile.Ukukhetha okuhlukahlukene okufanelekile kungathola amandla aphezulu wokubopha.Ngakho-ke, ama-adhesives athuthuke ngokushesha futhi abe yizinto ezisetshenziswa kakhulu ohlelweni lokubopha.
Njengamanje, izinamathiselo ezisetshenziswa kakhulu yizinamatheliso ze-isocyanate, izinamatheliso ezine-halogen kanye nezinamatheliso ze-phenolic resin.I-adhesive yayo ye-isocyanate iyingcina enhle yerabha nezinsimbi ezihlukahlukene.Ibonakala ngamandla amakhulu okubopha, ukumelana nokushaqeka okuhle kakhulu, inqubo elula, ukumelana nowoyela, ukumelana ne-solvent, ukumelana nophethiloli owuketshezi, ukumelana ne-asidi ne-alkali nezinye izakhiwo, kodwa ukumelana nezinga lokushisa kubi kancane..Irabha ye-Hydrochlorinated iwumkhiqizo otholwe ngokusabela kwenjoloba yemvelo ne-hydrogen chloride, enokuqina okuhle kwamakhemikhali futhi ayishisi.Izinamathiselo zenjoloba ezine-chlorine ezinokunamathela okuhle zingatholakala ngokuncibilikisa irabha ene-chlorine ku-ejenti efanele.Izinamathiselo zenjoloba ezine-chlorine zisetshenziselwa ikakhulukazi irabha ye-polar (injoloba ye-neoprene kanye nerabha ye-nitrile, njll.) nezinsimbi (insimbi, i-aluminium, Ingasetshenziswa futhi njengendawo yokuzivikela engaphezulu ngenxa yokumelana kwamanzi okuhle kakhulu nokumelana kwamanzi olwandle.
