Zomatira ndi zinthu zomwe zimalumikiza zinthu zoyandikana.Zomatira zitha kugawidwa kukhala zomatira, zomangira, zomatira zomangira, zomata zomata, zomatira, zomatira ndi zomatira, ndi zina zambiri, molingana ndi njira zosiyanasiyana zomangira ndi njira zogwirira ntchito.
Tackifier: amatanthauza zinthu zomwe zimatha kukulitsa kukhuthala kwa zomatira zosayaka, monga petroleum resin, coumarone resin, styrene indene resin, non-thermally reactive p-alkylphenol formaldehyde resin ndi pine tar.Kumamatira kumatanthauza mphamvu kapena ntchito yofunikira kuti muchotse mafilimu awiri amtundu umodzi pambuyo ponyamula katundu wochepa komanso nthawi yochepa yopumira, ndiko kuti, kudzimana.The tackifier amangowonjezera kukhuthala kwa zinthu za mphira panthawi yokonza zinthu zamitundu yambiri, zomwe zimathandizira kulumikizana pakati pa zigawo za rabala.Imakulitsa kwambiri mgwirizano pakuwonjezera kutsatsa kwakuthupi, ndipo ili m'gulu la zothandizira kukonza.
Zomatira za Impregnation: zomwe zimadziwikanso kuti zomatira zosalunjika, zimatanthawuza madzi omwe ali ndi mawonekedwe a viscous omwe amaphimba pamwamba pa nsalu ya fiber kapena kulowa mkati mwa kusiyana kwa nsalu kudzera munjira ya impregnation.Nsaluyo imamangiriridwa ndi mankhwala, ndipo madzi opangira mimbawa amatchedwa "imregnating adhesive", monga gawo lachitatu la NaOH emulsion bonding system of resorcinol, formaldehyde ndi latex, kapena RFL system, yomwe imapangitsa kuti mphira ndi fiber zikhale bwino.imodzi mwa njira zazikulu.Kwa ulusi wosiyanasiyana, mapangidwe amadzimadzi opangira mimba ndi osiyana.Mwachitsanzo, latex (L chigawo) ikhoza kukhala NRL kapena butyl pyridine latex, ndipo kuchuluka kwa resorcinol ndi formaldehyde kungasinthidwenso.Kwa ulusi womwe ndi wovuta kulumikiza monga poliyesitala, aramid ndi magalasi fiber, kuwonjezera pa kapangidwe ka RFL, zosakaniza zina zomwe zimathandizira kulumikizana ziyenera kuwonjezeredwa, monga isocyanate, silane coupling agent, etc.
Zomangira zomangira: Zomwe zimatchedwanso zomatira mwachindunji, zimasakanizidwa pagulu panthawi yosakanikirana, ndipo panthawi yavulcanization, kugwirizanitsa mankhwala kapena kutsekemera kwamphamvu kumachitika pakati pa malo omwe amamatira kuti apange chinthu chomangika cholimba, monga interlayer wamba.Hydroquinone donor-methylene donor-silica bonding system (m-methyl white system, HRH system), triazine bonding system.Mu mtundu uwu wa zomatira, palibe wosanjikiza wapakatikati potengera zomatira pamtunda wa zida ziwiri zomwe zimapangidwira.Zomatirazi zimagwiritsidwa ntchito kwambiri popanga mgwirizano wamphamvu komanso wolimba pakati pa zida za mphira ndi mafupa.
Binder (zomatira): amatanthauza chinthu chomwe chimamatira ufa wosapitirira kapena zinthu za ulusi pamodzi kuti zikhale zonse mosalekeza, monga zomata zapapepala, zomata zosalukidwa, zomata za asbesitosi, ufa Zomangira zomwe zimagwiritsidwa ntchito ponyowa granulation nthawi zambiri zimakhala zamadzimadzi kapena zocheperako. zinthu zamadzimadzi, ndi zomangira ndi ufa zimasakanizidwa mofanana ndi kusonkhezera kothamanga kwambiri ndi njira zina, ndipo chomangiracho chimapereka mphamvu yolumikizana yolumikizana.
Adhesivepromotingagen: imatanthawuza chinthu chamankhwala chomwe chimapanga mwachindunji kutengeka kwakuthupi kapena kulumikizana kwamankhwala pakati pa zinthu, koma kumatha kulimbikitsa kuchitika kwa zomatira, monga kumatira kwa mphira ndi zitsulo zokutidwa ndi mkuwa.Mchere wa organic cobalt womwe umagwiritsidwa ntchito pochita izi ndiwolimbikitsa zomatira.Wothandizira womatira uyu amawonjezedwanso mwachindunji kumaguluwo ngati chophatikizira ndipo amathandizira pakutentha kwambiri kwa vulcanization.
Zomatira (zomatira): zimatanthawuza gulu lazinthu zomwe zimalumikiza magawo awiri kapena kuposerapo (kapena zida) palimodzi, makamaka ngati guluu kapena tepi yomatira, ndikukwaniritsa kumamatira kudzera mu kupopera mbewu mankhwalawa, kupaka ndi kumata.Cholinga.Njira yolumikizira iyi ndi kupanga cholumikizira chapakatikati chokhala ndi zomatira monga chigawo chachikulu pakati pa zinthu ziwirizi, monga kugwirizana pakati pa mphira wovunda, kugwirizana pakati pa mphira wovunda ndi khungu, matabwa ndi zitsulo.Zomatira Zake zomwe ndi magwiridwe antchito, ndipo njira yolumikizira imatsimikizira zotsatira zomangira.
Pakati pa zomatira zomwe tatchulazi, zomatira zokhala ndi ntchito zambiri, mlingo waukulu ndi njira yosavuta yopangira ntchito ndi zomatira.Pali mitundu yambiri ya zomatira, ndipo machitidwe awo ndi osiyana.Kusankha mitundu yoyenera kungapeze mphamvu zomangirira kwambiri.Choncho, zomatirazo zakula mofulumira ndipo zakhala zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga mgwirizano.
Pakalipano, zomatira zomwe zimagwiritsidwa ntchito kwambiri ndi zomatira za isocyanate, zomatira za halogen ndi zomatira za phenolic resin.Zomatira zake za isocyanate ndi zomatira zabwino za mphira ndi zitsulo zosiyanasiyana.Amadziwika ndi mphamvu yomangirira kwambiri, kukana kwambiri kugwedezeka, njira yosavuta, kukana kwamafuta, kukana zosungunulira, kukana kwamafuta amadzimadzi, kukana kwa asidi ndi alkali ndi zinthu zina, koma kukana kutentha kumakhala kosauka pang'ono..Hydrochlorinated rabara ndi mankhwala opangidwa ndi momwe mphira wachilengedwe ndi hydrogen chloride amachitira, omwe amakhala ndi kukhazikika kwamankhwala abwino ndipo samawotcha.Zomatira mphira wa klorini wokhala ndi zomatira zabwino zitha kupezeka posungunula mphira wa chlorinated mu njira yoyenera.Zomatira za mphira wa klorini zimagwiritsidwa ntchito makamaka pa mphira wa polar (rabala ya neoprene ndi mphira wa nitrile, etc.) ndi zitsulo (zitsulo, aluminiyamu, Zitha kugwiritsidwanso ntchito ngati zokutira zotetezera pamwamba chifukwa cha kukana madzi abwino komanso kukana madzi a m'nyanja.
