Lub façade ntawm lub tuam tsev pheej mus rau ultraviolet radiation, kub hloov, atmospheric nag lossis daus, thiab lwm yam, vim hais tias qhov ruaj thiab zoo siab ntawm nws cov phab ntsa plays lub luag hauj lwm tseem ceeb thiab muaj peev xwm ua kom lub neej ntawm lub tsev thiab khaws nws txoj kev zoo nkauj, zoo nkauj thiab zoo nkauj. Xws li ib txheej yuav muab ib qho façade rau chav ua haujlwm sab nraum zoov. Nws tuaj yeem ua kom tsis muaj teeb meem ntawm lub façade, kho nws, npaj rau kev pleev xim los yog dai kom zoo, piv txwv li, nrog vuas luaj los yog pob zeb .
Hom thiab lub hom phiaj ntawm cov khoom siv façade
Facade putty, raws li ib txoj cai, muaj peb lub ntsiab loj - ib qho khoom ua ke, ib tus neeg saib xyuas kev sib tw thiab fibers, ntau feem ntau cov khoom cua. Cov xuab zeb yog siv los ua ib qho kev tivthaiv hauv façade; Nyob ntawm seb qhov luaj li cas ntawm cov zauv feem ntau hauv cov av, qhov chaw ua si yuav ua tau zoo los yog textured.
Tam sim no, feem ntau nrov siv façade ntsaws rau xis mas thiab polymer. Thaum tov cov dej ciav dej sib tov nrog dej, tus cement-binding agent los yog polymer-glues cov xuab zeb ua ke, ua ib lub hnab yas, homogeneous uas yog sib npaug ua ntawv thov rau phab ntsa. Raws li cov dej evaporates, tus neeg ua hauj lwm losis tswvyim dabtsi pab thiab ua kom muaj zog tiv thaiv. Fibers thiab lwm yam tshwj xeeb fillers raug ntxiv los ua kom lub zog, ruaj khov, dej tsis txhuam ntawm qhov kev txwv thiab txo qhov yuav ua rau nws tawg. Cov kev tso dag no muab kev ruaj siab, ruaj xim txheej, ntxiv lub suab thiab cua sov, kev nyab xeeb nyob ib puag ncig. Tiav qhov teeb meem tawm sab nrauv rau sab nraud ua haujlwm ntawm lub hauv paus ntawm cov cement muab cov xim ruaj khov, nws yog ib qho ua rau tsis muaj dej, qhov sov thiab kub hloov. Txawm li cas los, nws cov disadvantage, tsis zoo li acrylic, yog tsawg plasticity thiab cov cuab yeej ntawm shrinkage, uas ua rau lub tsos ntawm tawg thiab xav tau rov qab shpatlevaniya. Nws tuaj yeem siv los npog yuav luag txhua tus substrate, tabsis rau sab nraum zoov ua hauj lwm rau kev ua vaj tse, acrylic putty yog kev pom zoo ntxiv.
Lub acrylic putty txheej kuj yog ruaj thiab noo noo resistant, resistant rau ib puag ncig influences. Tib lub sij hawm, nws qhov zoo tshaj yog vapor permeability, ductility, thiab, raws li, non-shrinkage. Lub ntsiab qhov tsis zoo ntawm cov polymer fillers yog tus nqi siab tshaj plaws.
Rau sab nraum zoov ua hauj lwm ntawm ntoo tsim ib tug tshwj xeeb polymer waterproof putty - nws ntxiv ntoo resins, uas ua rau nws ntau elastic, vim uas nws ntog zoo rau ntawm ntoo nto. Qhov kev nkag siab zoo li no yog ua rau kev ntxoov ntxoo "nyob rau hauv tsob ntoo", vim nws tsis yog li ntawd rau ntawm qhov chaw ntim raug kho.
