Ibifatika ni ibintu bihuza ubuso bwibintu hamwe.Ibifatika birashobora kugabanywamo ibifatika, ibifunga, ibikoresho bifatanyiriza hamwe, abamamaza porogaramu, abatekamutwe hamwe nudusimba twangiza, nibindi, ukurikije uburyo butandukanye bwo guhuza hamwe nuburyo bukoreshwa.
Tackifier: bivuga ibintu bishobora kongera ubwiza bwamavuta adasukuye, nka peteroli ya resin, coumarone resin, styrene indene resin, idafite ubushyuhe bwa p-alkylphenol formaldehyde resin na pine.Adhesion bivuga imbaraga cyangwa akazi gasabwa kugirango ukureho firime ebyiri zabahuje ibitsina nyuma yumutwaro muto nigihe gito cyo kumurika, ni ukuvuga kwifata.Tacifier yongerera gusa ubuso bwibikoresho bya reberi mugihe cyo gutunganya ibicuruzwa byinshi bya reberi, byorohereza inzira yo guhuza ibice bya reberi.Itezimbere cyane cyane guhuza ibikorwa byongera adsorption yumubiri, kandi iri mubyiciro byo gutunganya ibikoresho.
Kwinjiza impregnation: bizwi kandi nka indirect adhesive, bivuga amavuta yo guteramo ibintu birimo ibibyimba bitwikiriye hejuru yigitambara cya fibre cyangwa byinjira mumyanya yimbere yigitambara binyuze muburyo bwo gutera akabariro.Umwenda uhujwe na chimique, kandi aya mazi yinjizamo bita imiti yinjiza, nkibice bitatu bigize NaOH emulsion ihuza sisitemu ya resorcinol, formaldehyde na latex, cyangwa sisitemu ya RFL, aribyo kunoza imikorere ya reberi na fibre.bumwe mu buryo bw'ingenzi.Kuri fibre zitandukanye, ibigize amazi yinjiza biratandukanye.Kurugero, latex (L ibice) irashobora kuba NRL cyangwa butyl pyridine latex, kandi ingano ya resorcinol na formaldehyde nayo irashobora guhinduka.Kuri fibre igoye guhuza nka polyester, aramide na fibre fibre, usibye ibihimbano bya RFL, ibindi bintu bifasha guhuza bigomba kongerwaho, nka isocyanate, agent ya silane, nibindi.
Igikoresho cyo guhuza: Bizwi kandi nk'ibifatika bitaziguye, bivangwa mu ruganda mu gihe cyo kuvanga, kandi mu gihe cyo kurunga, guhuza imiti cyangwa ibintu bikomeye bya adsorption bibaho hagati y’imiterere kugira ngo bibe ibintu bifatika, nk'imikoranire isanzwe.Hydroquinone abaterankunga-methylene baterankunga-sisitemu yo guhuza (m-methyl yera, sisitemu ya HRH), sisitemu yo guhuza triazine.Muri ubu bwoko bwo gufatira hamwe, nta gipimo giciriritse gishingiye ku gufatira hejuru y’ibikoresho byombi aho inkwano ikorerwa.Iyi miti ikoreshwa cyane mugukora ubumwe bukomeye kandi burambye hagati ya reberi nibikoresho bya skeleton.
Binder (adhesive): bivuga ibintu bifata ifu idahagarara cyangwa ibikoresho bya fibrous hamwe kugirango bikore byose bikomeza, nkimpapuro zipapuro, impapuro zidoda, ifu ya asibesitosi, ifu Ihuza rikoreshwa mugusya cyane ni amazi cyangwa igice. ibintu bitemba, hamwe na binder hamwe nifu bivangwa kimwe no kwihuta cyane hamwe nubundi buryo, kandi binder itanga imbaraga zifatika zo guhuza.
Adhesivepromotingagen: bivuga ibintu bya chimique bitanga mu buryo butaziguye adsorption yumubiri cyangwa imiti ihuza ibikoresho, ariko irashobora guteza imbere kwizirika, nko muguhuza reberi nicyuma gikozwe mu muringa.Umunyu ngugu wa cobalt ukoreshwa muribwo buryo bwo kwamamaza.Iyi poroteri ya adhesion nayo yongewe muburyo butaziguye nkibikoresho byo guhuza kandi bigira uruhare mubikorwa byo hejuru yubushyuhe bukabije.
Gufata neza (gufatira): bivuga icyiciro cyibintu bihuza ibice bibiri cyangwa byinshi (cyangwa ibikoresho) hamwe, cyane cyane muburyo bwa kole cyangwa kaseti, kandi bikageraho bifatanye no gutera, guteramo no gufata inzira.Intego.Ubu buryo bwo guhuza ni ugukora urwego ruciriritse rufatanije hamwe nurufatiro nkigice cyingenzi hagati yubuso bwibikoresho byombi, nko guhuza reberi y’ibirunga, guhuza reberi y’uruhu n’uruhu, ibiti n'ibyuma.Gufata Imiterere yacyo n'imikorere yayo, kandi inzira yo guhuza igena ingaruka zo guhuza.
Mubintu byavuzwe haruguru, ibifatika hamwe nibisabwa, dosiye nini hamwe nuburyo bworoshye bwo gukora ni ibifatika.Hariho ubwoko bwinshi bwamavuta, kandi imikorere yabo iratandukanye.Guhitamo ubwoko bukwiye birashobora kubona imbaraga zo guhuza imbaraga.Kubwibyo, ibifatika byateye imbere byihuse kandi byahindutse ibintu bikoreshwa muburyo bwo guhuza.
Kugeza ubu, ibisanzwe bikoreshwa cyane ni isocyanate yometseho, halogen irimo ibiyiko hamwe na fenolike resin.Ibikoresho bya isocyanate bifata neza na reberi hamwe nibyuma bitandukanye.Irangwa nimbaraga zihuza cyane, kwihanganira ihungabana ryiza, inzira yoroshye, kurwanya amavuta, kurwanya ibishishwa, kurwanya amavuta ya aside, aside na alkali birwanya nibindi bintu, ariko kurwanya ubushyuhe ni bike..Hydrochlorine reberi nigicuruzwa kibonwa nigisubizo cya reberi karemano na hydrogène chloride, ifite imiti ihamye kandi ntigitwike.Ibikoresho bya chlorine bifata neza birashobora kuboneka mugushonga reberi ya chlorine muburyo bukwiye.Ibikoresho bya Chlorine bifata cyane cyane kuri reberi ya polar (neoprene rubber na nitrile rubber, nibindi) hamwe nicyuma (ibyuma, aluminium, Irashobora kandi gukoreshwa nkigifuniko cyo gukingira hejuru kubera kurwanya amazi meza no kurwanya amazi yinyanja.
