Kev tsim kho kev lag luam tau hloov zuj zus mus tas li thiab kev tsim kho tshiab thiab thev naus laus zis tau tsim los ua kom nws zoo dua.Ib qho kev tsim kho tshiab no yog kev siv cov khoom siv hluav taws xob rov ua dua tshiab hauv cov khoom siv tshuaj polymer.Redispersible polymer hmoov yog siv los ua binders hauv kev tsim cov khoom no.Nws yog cov hmoov dawb tau los ntawm emulsion polymerization ntawm monomers.Tom qab ntawd cov hmoov ua tiav rau hauv ib lub polymer uas tuaj yeem yooj yim redispersed hauv dej.Redispersible polymer hmoov muaj ntau yam khoom uas ua rau lawv zoo tagnrho binders rau polymer mortar khoom.Nyob rau hauv tsab xov xwm no, peb tshawb nrhiav lub luag haujlwm ntawm dispersible polymer hmoov nyob rau hauv cov khoom siv polymer mortar thiab vim li cas nws thiaj li yuav tsum tau ua kom yooj yim.
Cov khoom ntawm redispersible latex hmoov
Redispersible polymer hmoov muaj ntau yam khoom uas ua rau lawv tsim nyog siv rau hauv cov khoom siv tshuaj polymer.Ib qho ntawm cov khoom tseem ceeb ntawm cov hmoov yog lawv lub peev xwm los txhim kho cov khoom adhesion thiab saj zawg zog.Qhov no yog vim tias cov hmoov yog tsim los ntawm cov khoom siv polymer uas raug tshem tawm hauv dej.Thaum cov hmoov sib tov nrog dej, nws tsim ib qho emulsion ruaj khov uas tuaj yeem siv tau yooj yim rau substrate nto.Raws li cov dej evaporates, cov khoom siv polymer sib txuas ua ke los tsim cov yeeb yaj kiab txuas ntxiv uas txuas cov khoom lag luam rau hauv substrate.
Lwm cov cuab yeej ntawm dispersible polymer hmoov yog lawv cov dej tsis kam.Cov hmoov yog hydrophobic, uas txhais tau tias nws repels dej.Qhov no ua rau cov khoom siv polymer mortar ntau dej resistant, tiv thaiv lawv los ntawm kev tawg thiab deteriorating thaum lawv los nyob rau hauv kev sib cuag nrog noo noo.Cov cuab yeej no tseem ua rau cov khoom siv tau ntev dua vim tias lawv tuaj yeem tiv taus dej ntev ntev.
Redispersible latex hmoov kuj muaj cov nplaum zoo heev.Nws tsim ib qho kev sib raug zoo ntawm cov tshuaj khib thiab cov substrate, txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom.Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv polymer mortar rau kev siv sab nrauv vim lawv xav tau kom muaj peev xwm tiv taus huab cua hnyav.
Vim li cas cov khoom siv polymer mortar xav tau kev hloov pauv siab
Polymer mortar khoom uas muaj redispersible polymer hmoov yuav tsum tau yooj yim vim lawv feem ntau siv nyob rau hauv sab nrauv daim ntaub ntawv raug rau ntau yam tej yam kev mob.Cov xwm txheej no tuaj yeem ua rau lub substrate nthuav dav thiab cog lus, ua rau cov khoom tawg thiab deterioration.Yog li ntawd, kev hloov pauv siab yuav tsum tau ua kom ntseeg tau tias cov khoom tuaj yeem tiv taus cov rog no yam tsis muaj kev tawg lossis tawg.
Polymer mortar khoom uas muaj redispersible polymer hmoov kuj siv nyob rau hauv daim ntawv thov sab hauv raug kev co thiab poob siab.Hauv cov xwm txheej no, kev hloov pauv siab yuav tsum tau ua kom ntseeg tau tias cov khoom tuaj yeem tiv taus cov rog no tsis muaj kev tawg lossis tawg.Kev hloov pauv siab kuj tseem txhawb nqa tag nrho kev ua tau zoo ntawm cov khoom vim nws tso cai rau nws ua raws li cov substrate thiab tuav nws cov ntawv cog lus lub zog nyob rau hauv siab.
Redispersible latex hmoov yog ib qho tseem ceeb hauv kev tsim cov khoom siv polymer mortar.Nws cov khoom sib txawv ua rau nws yog cov nplaum zoo rau cov khoom no, vim nws txhim kho lawv cov kev sib raug zoo, ua rau lawv cov dej tsis kam, thiab txhim kho lawv cov kav ntev.Polymer mortar khoom uas muaj redispersible polymer hmoov yuav tsum muaj siab yooj, tshwj xeeb tshaj yog rau sab nrauv daim ntaub ntawv raug rau ntau yam tej yam kev mob raws li zoo raws li sab hauv daim ntawv thov raug kev co thiab poob siab.Nrog rau lawv cov txiaj ntsig ntau, dispersible polymer hmoov yog hloov lub ntsej muag ntawm kev tsim kho kev lag luam los ntawm kev hloov cov khoom siv tsim, uas ua rau cov khoom siv tau zoo thiab ruaj khov.
