High-elasticity waterproofing thiab sealant emulsions yog ib chav dej ntawm cov dej-raws li polymer emulsions feem ntau yog siv rau vaj tse waterproofing, sib koom sealing, thiab substrate tiv thaiv. Lawv cov yam ntxwv tseem ceeb yog tsim cov zaj duab xis nrog zoo elasticity thiab elongation peev xwm; zaj duab xis tuaj yeem deform nyob rau hauv tandem nrog me me expansion, contraction, txav, los yog hloov ntawm substrate, yog li txo qhov kev pheej hmoo ntawm tawg los yog foob tsis ua hauj lwm. Piv nrog rau cov txheej txheem architectural txheej emulsions, cov emulsions tseem ceeb ntawm kev sib npaug ntawm elasticity, adhesion, waterproofing kev ua tau zoo, thiab durability.
Cov emulsions no nthuav tawm zoo heev yooj thiab elastic rov qab. Thaum tsim zaj duab xis, lawv feem ntau tsim cov mos mos, txuas ntxiv polymer txheej muaj peev xwm ntawm deforming nyob rau hauv nro, compression, los yog me me substrate txav, thiab tom qab ntawd rov qab mus rau nws thawj lub xeev thaum lub sab nraud quab yuam raug tshem tawm. Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb rau kev tsim cov phab ntsa, lub ru tsev, chav dej, thiab ntau yam kev sib koom ua ke, vim nws txo qhov kev pheej hmoo ntawm cov kab nrib pleb uas tshwm sim los ntawm yam xws li substrate shrinkage lossis kub hloov pauv.
Cov emulsions no muaj qhov zoo adhesion thiab waterproofing zog. Cov yeeb yaj kiab txuas ntxiv tsim tom qab daim ntawv thov zoo npog microscopic pores thiab deg tsis xws luag, txo cov dej noo nkag mus rau hauv cov substrate. Tsis tas li ntawd, cov emulsion yuav tsum tau ua raws li kev tsim kho cov txheej txheem sib xyaw ua ke- xws li pob zeb, cement mortar, thiab hlau - kom ntseeg tau tias muaj kev ruaj ntseg ntawm cov txheej txheem waterproofing thiab nto. Kev sib xyaw ua ke ntawm cov adhesion muaj zog thiab elasticity txhim khu kev ncaj ncees ntawm cov txheej txheem dej tsis zoo thaum lub sijhawm ua haujlwm ntev -.
High -elasticity waterproofing thiab sealant emulsions feem ntau xav tau kev ua haujlwm zoo rau dej, huab cua, kub siab, thiab kev laus. Architectural waterproofing cov ntaub ntawv yog tas li raug los nag, ultraviolet (UV) hluav taws xob, thermal cycling, thiab fluctuating humidity; Kev ua haujlwm tsis txaus tuaj yeem ua rau muaj teeb meem xws li chalking, tackiness, embrittlement, lossis cracking. Yog li ntawd, kev tsim qauv tsim muaj xws li kho cov qauv polymer thiab koom nrog cov khoom siv ntxiv kom ntseeg tau tias cov txheej txheem khaws nws cov elasticity thiab kev tiv thaiv muaj peev xwm txawm tias ntev - ib puag ncig raug.
Cov emulsions no feem ntau tshwm sim los ntawm lawv cov eco-tus phooj ywg, dej-raws li xwm thiab yooj yim ntawm daim ntawv thov. Los ntawm kev siv dej ua qhov nruab nrab dispersion, kev siv cov kuab tshuaj organic yog txo, ua rau qis qis qis thaum siv; lawv tuaj yeem siv tau los ntawm kev siv txhuam hniav, dov, lossis tshuaj tsuag. Cov khoom ntawm emulsion-xws li viscosity, solids content, film-forming speed, and elasticity- tuaj yeem hloov kho raws li cov kev thov tshwj xeeb kom ua tau raws li cov kev cai sib txawv ntawm vov tsev, phab ntsa sab nrauv, chav ua noj thiab chav dej, underground engineering, thiab kev tsim cov pob qij txha.
