Adhesives zvinhu zvinobatanidza nzvimbo dziri pedyo dzechinhu pamwechete.Zvinamira zvinogona kupatsanurwa kuita zvinonamira, zvisungo, zvinonamira zvisungo, zvinosimudzira zvinonamatira, tackifiers uye inpregnating adhesives, nezvimwe, zvinoenderana neakasiyana mabatiro maitiro uye maitiro ekushanda.
Tackifier: inoreva zvinhu zvinogona kuwedzera viscosity yezvinonamira zvisina kuvharwa, senge petroleum resin, coumarone resin, styrene indene resin, isiri-thermally reactive p-alkylphenol formaldehyde resin uye pine tar.Adhesion inoreva simba kana basa rinodiwa kusvuura mafirimu maviri ane homogeneous mushure memutoro mudiki uye nguva pfupi yekumisikidza, ndiko kuti, kuzvinamatira.Iyo tackifier inongowedzera iyo yekumusoro viscosity yezvinhu zverabha panguva yekugadziriswa kweakawanda-layer zvigadzirwa zverabha, izvo zvinofambisa nzira yekubatanidza pakati pematanho erabha.Iyo inonyanya kuvandudza iyo yekubatanidza maitiro nekuwedzera iyo yemuviri adsorption, uye ndeye chikamu chekugadzirisa aids.
Impregnation adhesive: inozivikanwawo seisina kunanga inonamira, inoreva iyo impregnation fluid ine viscous zvikamu zvinofukidza pamusoro pemucheka wefiber kana kupinda mukati megeji remukati mejira kuburikidza neiyo impregnation process.Mucheka unosungirirwa nekemikari, uye iyi inpregnating liquid inonzi impregnating adhesive, yakadai sezvikamu zvitatu zveNaOH emulsion bonding system ye resorcinol, formaldehyde uye latex, kana RFL system, iyo inovandudza kusungirirwa kwerubha uye fiber.imwe yenzira huru.Kune mafibhi akasiyana, kuumbwa kweiyo impregnating fluid yakasiyana.Semuenzaniso, latex (L chikamu) inogona kuva NRL kana butyl pyridine latex, uye huwandu hwe resorcinol uye formaldehyde hunogonawo kuchinjwa.Kune fiber inonetsa kusungirira senge polyester, aramid uye girazi fiber, kuwedzera kune RFL kuumbwa, zvimwe zvinongedzo zvinokonzeresa kusungirirana zvinofanirwa kuwedzerwa, senge isocyanate, silane coupling agent, nezvimwe.
Bonding agent: Iyo inozivikanwawo seinonamira yakananga, inosanganiswa mukomboni panguva yekusanganiswa, uye panguva yevulcanization, kemikari bonding kana yakasimba substance adsorption inoitika pakati penzvimbo kuti inamerwe kuita chinhu chakasimba chakasungwa, senge chakajairika interlayer.Hydroquinone donor-methylene donor-silica bonding system (m-methyl white system, HRH system), triazine bonding system.Mune rudzi urwu rwekunamatira, hapana chepakati chepakati chinobva pakunamatira pamativi ezvinyorwa zviviri apo chisungo chinogadzirwa.Iri rinonamira rinonyanya kushandiswa kugadzira chisungo chakasimba uye chakasimba pakati perubha uye skeleton zvinhu.
Binder (adhesive): inoreva chinhu chinonamatira discontinuous poda kana fibrous zvinhu pamwechete kuti zviumbe zvinoramba zvichiitika, senge bepa pulp binder, non-woven binder, asbestos binder, powder Mabhainda anoshandiswa mukunyorova granulation kazhinji mvura kana semi- zvinhu zvemvura, uye binder nehupfu zvakasanganiswa zvakafanana nekukurumidzira kukuru uye dzimwe nzira, uye binder inopa simba rakabatana rekubatanidza.
Adhesivepromotingagen: inoreva chinhu chemakemikari chinoburitsa zvakananga adsorption yemuviri kana kemikari chisungo pakati pezvinhu, asi inogona kusimudzira kuitika kwekunamira, sekunamira kwerabha nendarira-yakaputirwa simbi.Iyo organic cobalt munyu inoshandiswa mukuita iyi inosimudzira yekunamatira.Uyu anosimudzira adhesion anowedzerwawo zvakananga kumubatanidzwa seanosanganisa mumiriri uye anoita basa mukupisa tembiricha vulcanization process.
Adhesive (adhesive): inoreva kirasi yezvinhu zvinobatanidza zvikamu zviviri kana kupfuura (kana zvinhu) pamwechete, zvakanyanya muchimiro cheglue kana tepi yekunamira, uye kuwana adhesive kuburikidza nekupfapfaidza, kukoira uye kunamira maitiro.Chinangwa.Iyi nzira yekubatanidza ndeyekugadzira yepakati yekubatanidza dhizaini ine inonamira sechinhu chikuru pakati pehuso hwezvinhu zviviri izvi, sekubatanidza pakati perabha ine vulcanized rabha, kubatanidza pakati pehulcanized rabha neganda, huni nesimbi.Adhesive Yayo zvimiro uye mashandiro, uye iyo yekubatanidza maitiro inosarudza iyo yekubatanidza maitiro.
Pakati pezvinonamira zvataurwa pamusoro apa, iyo inonamira ine yakakura application, yakakura dosi uye yakapusa mashandiro maitiro ndiyo inonamira.Kune marudzi akawanda ezvokunamatira, uye maitiro avo akasiyana.Kusarudza akasiyana akakodzera anogona kuwana yakakwirira yekubatanidza simba.Naizvozvo, zvinonamira zvakakura nekukurumidza uye zvave zvinhu zvinonyanya kushandiswa mukubatanidzwa.
Parizvino, anonyanya kushandiswa adhesives isocyanate adhesives, halogen-ine adhesives uye phenolic resin adhesives.Iyo isocyanate adhesive yakanaka yekunamira yerabha uye akasiyana simbi.Iyo inoratidzirwa nehupamhi hwekubatanidza simba, yakanakisa kuvhunduka kuramba, nyore maitiro, mafuta kuramba, solvent resistance, liquid mafuta kuramba, acid uye alkali resistance uye zvimwe zvivakwa, asi tembiricha kuramba ishoma..Hydrochlorinated rubber chigadzirwa chinowanikwa nekuita kwerabha yechisikigo uye hydrogen chloride, ine yakanaka kugadzikana kwemakemikari uye isingapisi.Chlorinated rubber adhesives ane yakanaka adhesion inogona kuwanikwa nekunyungudutsa chlorinated rabha mune yakakodzera mumiriri.Chlorinated rubber adhesives inonyanya kushandiswa kune polar rubber (neoprene rubber uye nitrile rubber, etc.) uye simbi (simbi, aluminium, Inogonawo kushandiswa sechinhu chinodzivirira chepamusoro nekuda kwekudzivirira kwayo kwemvura uye kushorwa kwemvura yegungwa.
