Lesi sihloko sikhetha kakhulu i-MMA, BA, AA njengama-monomers, futhi sidingida izici ze-graft polymerization nazo, njengokulandelana kokwengezwa, inani elingeziwe kanye nezinga lokushisa lokusabela kwesiqalisi kanye ne-monomer ngayinye, futhi sithola izimo ezinhle kakhulu zenqubo ye-graft polymerization. I-rubber iqala ukucwiliswa, bese ishukunyiswa futhi ichithwe nge-solvent exutshwe ku-70 ~ 80 ° C, bese i-initiator BPO yengezwe ngamaqoqo. I-monomer yokuqala ye-MMA encibilikiswe nge-BOP yengezwa ku-80 ~ 90 ° C imizuzu engu-20, bese yengezwa nge-monomer yesibili ye-BPO, ngemva kweminye imizuzu engu-20, engeza i-monomer yesithathu ku-84~88 ℃ bese ugoqa imizuzu engu-45, gcina. kufudumala amahora angu-1.5~2, bese uthola i-CR/MMA-BA-AA yezindlela ezintathu zokunamathisela i-polymerization, amandla e-Peel makhulu CR/MMA-BA, inani layo lingu-6.6 KN.m-1.
Amagama angukhiye: Ingcina ye-Neoprene, ingcina yezicathulo, ingcina ye-neoprene enezingxenye eziningi.
I-cellulose etherMCfuthiI-HPMCibe nokusebenza okuhle kokuhlakazeka, i-emulsification, ukuqina, ukunamathela, ukwakheka kwefilimu, ukugcinwa kwamanzi, futhi ibe nokuncibilika okuhle kakhulu kwamanzi, umsebenzi ongaphezulu, ukuzinza, kanye nokuncibilika kuzinyibilikisi zemvelo.
Imikhiqizo eyinhloko ethuthukisiwe okwamanje i-RT series MC kanye nezinhlobo ze-HPMC, amamaki azo angu-50RT (Methylcellulose), 60RT (Hydroxypropylmethylcellulose), 65RT (Hydroxypropylmethylcellulose), 75RT (Hydroxypropylmethylcellulose), ahambisana namabanga e-DOW A Chemical Company, i-Metho Company, F kanye no-K, ngokulandelana.
Imikhiqizo yochungechunge lwe-RT iyizithasiselo eziwusizo kakhulu ezintweni zokwakha ngenxa yokuhlangana kwazo, ukuzinza kokumiswa nokugcinwa kwamanzi. Isibonelo, zingenziwa zibe "izinga eliphezulu le-ceramic wall and floor tile adhesives", eyaziwa ngokuthi i-rubber powder, esetshenziswe e-Beijing West Railway Station, umphumela muhle. Ngaphezu kwalokho, ingasetshenziswa njenge-electrolyte e-gelled kuma-electrolytic capacitor kanye namagridi e-electrode ahlanganisiwe ezintweni zikagesi, njenge-atropine, i-aminopyrine namakristalu anal emithini yemithi, nanjenge-thickener yama-emulsions amanzi kumapende. Kupende we-latex nopende oncibilika emanzini, ungasetshenziswa njenge-ejenti eyenza ifilimu, i-thickener, emulsifier ne-stabilizer, njll. ukunamathela kwesithombe sangemuva, impushana yerabha emanzisa kabusha, njll.
Amagama asemqoka: Methyl Cellulose, Hydroxy Propyl Cellulose, ingcina, isicelo.
Ukuthuthukiswa kweglue lesandla lepulasitiki elisekelwe emanzini
Eminyakeni yamuva nje, kusungulwe inqubo entsha yokunamathisela ifilimu yepulasitiki endabeni ephrintiwe. I-BOPP (ifilimu ye-polypropylene e-biaxially oriented) ehlanganiswe nge-adhesive bese ihlanganiswa nento ephrintiwe ngemva kokucindezelwa isilinda serabha kanye nerola yokushisisa ukuze kwakhiwe iphepha. / Ipulasitiki 3-in-1 ukuphrinta. Lokhu kuhilela inkinga yokuhlanganiswa kwephepha nepulasitiki. I-BOPP iyinto engeyona i-polar, ngakho-ke, kunesidingo sokunamathisela okunamathela kahle kuzo zombili izinto ezipholile nezingezona ze-polar.
Ukuxuba okunamathelayo kwe-SBS ne-epoxy resin kunokuhambisana okuhle. I-SBS iyi-viscose ye-elastomer. Kungabonakala ejikeni layo lokuhluleka ukuthi ukuze kwandiswe amandla abhubhisayo anamathelayo e-viscose, kufanele ilawulwe eduze kwe-SBS: i-epoxy resin = 2:1. Kusukela ku-curve yamandla we-peel, kungabonakala ukuthi uma isilinganiso siphezulu, amandla e-peel azoba mkhulu, kodwa ukunamathela kuzokwanda. Ukuze ugweme ukunamathela, i-SBS: i-epoxy resin = 1:1 ~ 2.5:1 ingalawulwa ukuze ithole amandla e-peel akhuphuka kancane. Uma ucabangela ngokucophelela, thola i-SBS ku-glue eyinhloko: i-epoxy resin = 1: 1 ~ 3.5: 1.
Umsebenzi oyinhloko wokusebenzisa i-tackifying resin ukwandisa amandla okubopha we-matrix futhi uthuthukise ukumanzisa kweglue kanye nendawo yokubopha. I-tackifying resin esetshenziswe kulolu cwaningo i-rosin tackifier eyakhiwe i-rosin evamile kanye ne-rosin e-dimerized ngezilinganiso ezahlukene. Ngokuhlolwa okuningi, kuphetha ngokuthi iphesenti le-rosin encishisiwe ku-tackifier yi-22.5%, futhi amandla okucwenga eglue alungiselelwe ngokwalesi silinganiso yi-1.59N / 25mm (i-paper-plastic).
Inani le-tackifier linethonya elithile kuzakhiwo zokunamathela. Umphumela omuhle kakhulu uma isilinganiso seglue eyinhloko ne-tackifier singu-1:1. Amandla e-peel N/mm ipulasitiki-ipulasitiki 1.4, ipulasitiki yephepha 1.6.
Kulolu cwaningo, i-MMA isetshenziswe njenge-diluent ukuze kuhlanganiswe i-SBS ne-MMA. Izivivinyo zithole ukuthi ukusetshenziswa kwe-MMA akukwazi nje ukufeza inhloso yokuxova izakhi ku-colloid, kodwa futhi kunciphisa i-viscosity futhi kuthuthukise amandla okunamathela. Ngakho-ke, i-MMA iyi-diluent eguquliwe efanelekile. Ngemuva kokuhlolwa, inani le-MMA elisetshenzisiwe yinani eliphelele leglue 5% ~ 10% lifanelekile.
Njengoba i-viscose eyakhiwe kufanele incibilike emanzini, sikhetha i-latex emhlophe (i-polyvinyl acetate emulsion) njengesithwali esincibilika emanzini. Inani le-latex elimhlophe libalelwa ku-60% wesamba se-viscose. Ngemuva kokuthi i-viscose esekelwe emanzini i-emulsified ibe yisimo se-emulsion yamanzi ngokuhlakazeka kanye ne-emulsification ye-carrier emulsified, uma ukuhambisana kwayo okuhlanjululwe kungafanelekile ukusetshenziswa, kungahlanjululwa ngamanzi. Le ndlela yokuhlanjululwa kokubili inezindleko eziphansi futhi ayinabo ubuthi (asikho isidingo sokusebenzisa izincibilikisi zemvelo), futhi uhla olungcono kakhulu lwamanzi okuhlanza luyi-10% ~ 20%.
Ukuze kukhishwe insalela ye-viscose, kuhlolwa ukuthi isisombululo se-Na2CO3 se-dilute sisetshenziswa njenge-alkalizing agent, futhi umphumela ungcono kakhulu. Ithiyori yomphumela we-agent e-alkalizing ingase ibe ukuthi ukusabela kwe-saponification kwethula ama-ion aqinile e-polar, njengama-ion e-sodium, ukuze i-rosin acid yokuqala enganyibiliki iguqulwe ibe usawoti we-sodium e-Soluble. Ngaphezu kwalokho, uma isisekelo esinamandla kakhulu sengeziwe ku-glue, amandla okunamathela azolahleka, ukuze iglue ihluleke, ngakho-ke i-glue ayifaneleki imvelo ye-alkali.
Ukugeleza kwenqubo efanele.
