Mumunda wepolymer adhesives, kuwedzera kuchinjika kwave kuchiteverwa kwemakore mazhinji.Nekuda kwezvigadzirwa zvinogara uye zvinosimba, kuvandudzwa kweanomisikidza polymer adhesives kwave chinhu chekutanga.Imwe budiriro yakaratidza kuvimbisa kushandiswa kweRDP polymer binder blends.
RDP, kana kuti redispersible polymer poda, ipolymer yakaomeswa uye yakagayiwa kuita hupfu, iyo inogona kuparadzirwa zvakare mumvura kuti igadzire emulsion nyowani kana kupfekwa.Iyo poda inogadzirwa kubva kune akasiyana mapolymers anosanganisira vinyl acetate-ethylene (VAE), vinyl acetate-ethylene (VAEO), uye vinyl acetate-ethylene ester (VA-VE).RDP yakashandiswa zvakanyanya mukunamira uye kukoira maumbirwo pamwe nedhaka uye kongiri yekushandisa.Iyo yakanakisa firimu-yekugadzira zvimiro uye kugona kuvandudza adhesion, processability uye kuchinjika kunoita kuti ive sarudzo yakakurumbira mumaindasitiri mazhinji.
Kana yakasanganiswa nemamwe mapolymers akadai se polyvinyl acetate (PVA), styrene-butadiene rubber (SBR) uye carboxyl styrene-butadiene rubber (XSB), RDP inogona kuwedzera zvakanyanya kushanduka kwechigadzirwa chekupedzisira.Izvi zvinokonzerwa nekugona kweRDP kuwedzera mapurasitiki uye elasticity yemapolymers.Nekushandisa izvi zvinongedzo kugadzira firimu rakasimba, RDP inogona kuvandudza kusimba kwechisungo chechigadzirwa chekupedzisira uye kuita kuti irambe ichipikisa kuputika uye deformation.
Imwe yemabhenefiti makuru ekushandisa RDP polymer adhesive musanganiswa ndeyekuita kwavo kwakasiyana-siyana.Inogona kushandiswa pamhando dzakasiyana-siyana dze substrates, kusanganisira huni, kongiri uye simbi, pasina kupira kuita kana kusimba.Pamusoro pezvo, inogona kugadzirwa nemadhigirii akasiyana ekuchinja zvichienderana nezvinodiwa magumo-ekushandisa.Izvi zvinobvumira kuchinjika kukuru mukugadzirwa kwechigadzirwa uye kugona kugadzira mhinduro kune chaiwo maapplication.
Imwe bhenefiti yekushandisa RDP polymer binder musanganiswa ndeye mutengo-kushanda kwayo.Mutengo wayo wakaderera kana uchienzaniswa nemamwe marudzi ekunamira inoita kuti ive sarudzo inokwezva kune akawanda maindasitiri.Zvakare zvakareruka kushandisa uye zvinogona kuisirwa mumabikirwo aripo pasina shanduko huru.
RDP polymer binder blends inogona kuvandudza huwandu hwese hwechigadzirwa chekupedzisira.Nekuti inopa kuchinjika kukuru uye inonatsiridza kunamatira, inowedzera hupenyu hwechigadzirwa uye inoderedza kudiwa kwekugara kuchigadziriswa kana kutsiva.Nokufamba kwenguva, izvi zvinogona kukonzera kukosha kwekuchengetedza mari uye kuwedzera kugutsikana kwevatengi.
Iko kushandiswa kweRDP polymer binder blends kunoratidza chivimbiso chikuru mukuwedzera kuchinjika mumhando dzakasiyana dzezvigadzirwa.Kuita kwayo kwakasiyana-siyana, kudhura-kushanda, uye kugona kuvandudza kunaka kwese kwechigadzirwa chekupedzisira kunoita kuti ive sarudzo yakakosha mumaindasitiri mazhinji.Iko kushandiswa kweRDP polymer adhesive blends kungangoramba kuchikura mukuzivikanwa sezvo kudiwa kwezvakagara uye kusimba zvigadzirwa kuri kuramba kuchiwedzera.
