Polymer hmoov yog cov khoom siv ntxiv rau cov nplais nplaum kom tiv thaiv hollowing ntawm cov vuas.Ntxiv cov hmoov polymer rau cov nplaum sib xyaw ua kom cov nplaum nplaum muaj peev xwm sib txuas, tsim kom muaj kev sib raug zoo ntawm cov pobzeb thiab cov substrate.Hollow vuas qhia tias tsis muaj kev sib cuag txaus ntawm cov pobzeb thiab cov substrate, lossis tsis muaj cov nplaum ntawm ob qhov chaw.Hauv kev tsim kho, qhov hollowness ntawm cov vuas ib txwm tau suav tias yog qhov teeb meem tseem ceeb los daws.Polymer hmoov tau ua pov thawj zoo los tiv thaiv cov pobzeb hollowing thiab ua kom muaj kev nyab xeeb.Kab lus no tham txog yuav ua li cas cov hmoov polymer tuaj yeem tiv thaiv cov nplais hollowing hauv kev tsim kho.
Polymer hmoov feem ntau yog tsim los ntawm redispersible polymer hmoov (RDP) thiab feem ntau yog siv nyob rau hauv premixes, qhuav mix mortars thiab tsev kawm ntawv cov kev kawm.RDP yog cov hmoov uas muaj kev sib xyaw ntawm cov yas acetate thiab ethylene.Kev ua haujlwm ntawm cov hmoov polymer yog txhawm rau txhim kho cov khoom sib txuas ntawm cov txheej txheem sib txuas, ua kom lub zog sib txuas ntawm cov vuas ceramic thiab lub zog tensile ntawm cov nplaum.Cov txheej txheem sib txuas muaj cov hmoov polymer uas muab cov adhesion zoo rau ntau yam substrates xws li pob zeb, plastered pob zeb thiab plasterboard.
Cov hmoov polymer kuj ua raws li cov dej tuav cov neeg sawv cev, txhim kho tag nrho cov dej ntws ntawm cov binder sib tov.Polymer hmoov pab tswj cov dej noo hauv cov nplaum, yog li txuas ntxiv lub sijhawm ziab ntawm cov nplaum.Vim txoj kev ziab qeeb qeeb, cov nplaum tuaj yeem nkag mus rau hauv cov pobzeb thiab substrate nto, tsim kom muaj kev sib raug zoo.Lub thicker, qeeb-tsim nplaum sib tov pab tiv thaiv hollowing ntawm cov vuas los ntawm kev xyuas kom meej tias cov vuas yog embedded rau hauv cov nplaum thiab yuav tsis pop tawm thaum lub sij hawm installation.
Tsis tas li ntawd, cov hmoov polymer tiv thaiv cov nplais hollowing los ntawm kev tsim cov nplaum nplaum.Adhesives uas muaj cov hmoov polymer yog hloov tau thiab tuaj yeem nqus cov kev ntxhov siab uas cov plag tsev thiab phab ntsa tuaj yeem ntsib thiab txo txoj hauv kev tawg.Lub elasticity ntawm cov nplaum txhais tau hais tias nws yuav txav nrog cov pobzeb, txo qhov kev pheej hmoo ntawm kev kub siab ntawm cov pobzeb thiab tiv thaiv cov pobzeb los ntawm kev tawm.Qhov no kuj txhais tau hais tias cov nplaum tuaj yeem sau qhov khoob, qhov khoob thiab qhov tsis sib xws ntawm cov pobzeb thiab cov substrate, txhim kho qhov sib cuag ntawm ob.
Lwm qhov zoo dua ntawm cov hmoov polymer yog nws qhov zoo adhesion rau ntau hom substrates, uas yog qhov tseem ceeb los tiv thaiv hollowing ntawm cov vuas.Adhesives uas muaj cov hmoov polymer tuaj yeem txuas rau ntau yam ntaub ntawv, suav nrog ntoo, pob zeb thiab hlau.Lub peev xwm ua raws li cov substrates sib txawv txo qhov kev pheej hmoo ntawm cov vuas hollow hauv cov cheeb tsam uas raug rau siab, txav los yog kev co.Adhesives uas muaj cov hmoov polymer ua kom ntseeg tau tias cov vuas txuas rau lub substrate yog cov suab nrov thiab muaj peev xwm tiv taus kev ntxhov siab yam tsis muaj kev cuam tshuam los ntawm substrate.
Polymer hmoov kuj yog cov neeg siv-phooj ywg thiab siv tau yooj yim, ua rau lawv txoj kev daws teeb meem zoo rau kev tiv thaiv cov nplais hollowing.Cov khoom siv los ntawm cov hmoov nplej thiab tuaj yeem yooj yim tov nrog cov nplaum, ua rau cov txheej txheem installation sai thiab yooj yim dua.Adhesives muaj polymer hmoov xyuas kom meej tias cov vuas adheres tusyees rau lub substrate, txo qhov muaj peev xwm ntawm cov pobzeb hollowing thaum lub sij hawm installation.
Kev siv cov hmoov polymer hauv cov nplais nplaum tuaj yeem tiv thaiv cov nplais hollowing los ntawm kev txhim kho cov khoom sib txuas ntawm cov txheej txheem sib txuas.Kev ua haujlwm ntawm cov hmoov polymer yog txhawm rau txhim kho kev sib txuas ntawm lub zog ntawm cov nplaum rau lub substrate thiab ceramic vuas, tsim kom muaj kev sib raug zoo ntawm cov vuas ceramic thiab substrate.Nws kuj tseem tsim cov nplaum nplaum uas absorbs kev ntxhov siab thiab txav mus los, txo qhov kev pheej hmoo ntawm kev tawg thiab sib cais los ntawm substrate.Cov dej tuav cov khoom ntawm cov hmoov polymer kuj tseem siv sijhawm kom qhuav, kom ntseeg tau tias cov nplaum tuaj yeem nkag mus rau cov pobzeb thiab substrate nto rau kev sib txuas zoo dua.Thaum kawg, cov hmoov polymer yog cov neeg siv-phooj ywg thiab siv tau yooj yim thiab tuaj yeem txuas rau cov substrates sib txawv, ua rau nws yog qhov zoo tshaj plaws los tiv thaiv hollowing hauv cov vuas.
