Iko kuvandudzwa kwecomposite inochinjika kurongedza kusvika nhasi, kuderedza uye kubvisa organic zvinonyungudutsa mumubatanidzwa kwave kutungamira kwekubatana kwekuedza kweindasitiri yese. Parizvino, nzira dzakabatanidzwa dzinogona kubvisa zvachose zvinonyungudutsa mvura-based composite uye solvent-free composite. Nekuda kwesimba retekinoroji yemutengo uye zvimwe zvinhu, komputa isina solvent ichiri muchikamu che embryonic. Iyo inonamira yemvura inogona kushandiswa zvakananga mumushini uripo wakaoma wakasanganiswa, saka inogamuchirwa nevagadziri vepamba inochinjika yekurongedza, uye yakawana kukurumidza kusimudzira munyika dzekunze.
Mvura-based composite yakakamurwa kuita yakaoma composite uye yakanyorova composite, yakanyorova composite inonyanya kushandiswa mumapepa epurasitiki, pepa aluminium composite, chena latex inozivikanwa mumunda uyu. Mupurasitiki-yepurasitiki yakasanganiswa uye yepurasitiki-aluminium inosanganiswa, mvura-based polyurethane uye mvura-based acrylic polymer inonyanya kushandiswa. Mvura-based adhesives ine zvinotevera zvakanakira:
(1) Simba rakawanda rinoumbwa. Huremu hwehuremu hwemvura-inonamira ihombe, inova yakapetwa kakawanda kupfuura yepolyurethane adhesive, uye simba rayo rekubatanidza rinonyanya kuenderana ne van der Waals force, inova yepanyama adsorption, saka shoma shoma yeglue inokwanisa kuwana zvakati. high composite simba. Semuenzaniso, kana zvichienzaniswa ne-two-component polyurethane adhesive, mune inoumbwa firimu realuminium, iyo yakavharwa ye1.8g/m2 yeglue yakaoma inogona kuwana simba rakaumbwa re 2.6g/m2 yeglue yakaoma yezvikamu zviviri zve polyurethane adhesive.
(2) Yakapfava, yakanyatsokodzera iyo composite yealuminium plating firimu. Imwe-chikamu chemvura-based adhesives yakapfava kupfuura maviri-component polyurethane adhesives, uye kana yanyatsogadzika, polyurethane adhesives yakasimba kwazvo, nepo mvura-based adhesives akapfava zvakanyanya. Nokudaro, zvinyoro zvinyoro uye elasticity yemvura-based adhesive inonyanya kukodzera kune yakasanganiswa yealuminium plating firimu, uye hazvisi nyore kutungamira kuendeswa kwealuminium plating film.
(3) Haufanire kukura, mushure mekunge muchina unogona kutemwa. Iyo inosanganiswa yeimwe-chikamu chemvura-based adhesive haidi kuve yakura, uye inogona kushandiswa kune inotevera maitiro senge slitter uye mabhegi mushure mekuburuka. Izvi ndezvokuti simba rekutanga rekunamatira remvura-based adhesive, kunyanya kusimba kweshear, inovimbisa kuti chigadzirwa hachizobudisi "tunnel", kupeta uye mamwe matambudziko panguva yekubatanidza nekucheka. Uyezve, simba refirimu rinosanganiswa nemvura-based adhesives inogona kuwedzerwa ne50% mushure memaawa mana ekuiswa. Heino haisi iyo pfungwa yekukura, iyo colloid pachayo haiitike crosslinking, kunyanya nekuenzanisa kweglue, iyo inoumbwa simba inowedzera.
(4) Mutete anonamira layer, zvakanaka pachena. Nemhaka yekuti uwandu hwekunamatira hwemvura-based adhesives hudiki, uye kusungirirwa kwegluing kwakakwirira kudarika yezvinonyungudutsira-based adhesives, mvura inoda kuomeswa uye kubudiswa ishoma kudarika iyo inonyungudutsa-based adhesives. Mushure mekunge unyoro hwaoma zvachose, iyo firimu ichave yakanyatsojeka, nokuti iyo yakanamatira layer yakaonda, saka kujeka kweiyo composite zvakare kuri nani kupfuura iyo yeadhesive-based adhesive.
(5) Kuchengetedzwa kwezvakatipoteredza, kusina ngozi kuvanhu. Iko hakuna zvinonyungudutsa zvakasara mushure mekuomeswa kweadhesives-based adhesives, uye vagadziri vakawanda vanoshandisa mvura-based adhesives kudzivirira zvakasara zvinonyungudutsa zvinounzwa necomposite, saka kushandiswa kwemvura-based adhesives kwakachengeteka kugadzira uye hakukuvadzi hutano hwe. opareta.
