Cov lus qhia ntxaws ntxaws
Redispersible polymer hmoov (RDP)yog cov khoom siv polymer ntau yam uas tau siv dav hauv kev lag luam ntau yam. Nws yog qhov ntws tawm dawb, cov hmoov dawb uas tuaj yeem kho tau yooj yim hauv dej los ua qhov ruaj khov. Nov yog qee qhov kev siv thiab cov txiaj ntsig ntawm cov nyiaj liab polymer:
Kev Lag Luam Kev Tsim Kho Kev Tsim Kho:RDP yog dav nyob rau hauv kev tsim kho kev tsim kho nyob rau hauv kev tsim kho cov ntaub ntawv xws li cov khoom txuas ntxiv, thiab kev ua kom yuag yuag, thiab cov khoom siv tsis huv. Nws txhim kho cov khoom ntawm cov ntaub ntawv no, xws li adhesion lub zog, yoog tau, kev ua haujlwm, thiab dej tsis kam.
Phab Ntsa Putty thiab Skim Tsho:RDP yog feem ntau siv nyob rau hauv kev tsim khoom phab ntsa Putties thiab Skim tsho. Nws pab txhim kho cov haujlwm ua haujlwm, tawg tawm tsam, thiab cov nplaum ntawm cov khoom lag luam, kom meej thiab ruaj khov rau ntawm phab ntsa thiab nthab.
Ceramic pobzeb nplaum:RDP yog qhov tseem ceeb hauv cov khoom nplaum ceramic cov nplaum. Nws txhim kho cov nyiaj sib zog ntawm cov vuas thiab cov txheej txheem, txhim kho kom tau cov khoom siv hluav taws xob thermal, thiab muab dej tsis kam.
Kho Mortars:RDP yog siv hauv kev kho cov neeg nplua nyiaj, suav nrog kev ua vaj tse thiab cov khoom rov qab. Nws pab txhim kho adhesion rau yav dhau los substrate, nce lub durability thiab hloov tau ntawm cov khoom kho, thiab txhim kho kom tawg thiab shrinkage.
Thermal rwb thaiv tsev tshuab:RDP tseem siv hauv thermal rwb thaiv tsev tshuab, xws li sab nraud rwb thaiv tsev rwb thaiv tsev xov kab (EIFS). Nws txhim kho lub adhesion lub zog ntawm cov ntaub ntawv rwb thaiv tsev rau substrate, txhim kho lub durability thiab huab cua tsis kam.
Cov txiaj ntsig ntawm kev siv recispersible polymer hmoov muaj xws li:
Txhim kho Adhesion: RDP txhim kho cov khoom nplaum ntawm ntau yam ntaub ntawv, kom ua kom zoo dua kev sib raug zoo rau cov substrates thiab txo qhov kev pheej hmoo ntawm delamination lossis tsis ua hauj lwm.
Txhim Kho Yooj Yim:Qhov muaj kev sib txuam ntawm RDP hauv cov qauv txhawb kev hloov pauv tau yooj yim, tso cai ua tiav cov khoom tiav los tiv thaiv kev txav thiab deformation yam tsis muaj kev tawg.
Ua haujlwm tau:RDP txhim kho cov khoom ua haujlwm xws li pobzeb cov nplaum thiab phab ntsa tso, ua rau lawv yooj yim dua, thov, thiab kis.
Dej Tsis kam:Lub xub ntiag ntawm cov qauv tsim kho cov dej tsis kam, txo cov permeability ntawm cov ntaub ntawv thiab txhim kho lawv cov kev txav tsis huv lossis noo noo.
Txhim kho cov khoom siv neeg kho tshuab:RDP txhim kho lub zog, kev nruj me ntsis, thiab cuam tshuam tsis kam ntawm ntau cov ntaub ntawv, txhim kho lawv cov kev ua tau zoo thiab kev ua tau tag nrho.
Thaum siv cov hmoov nplej polymer, nws yog ib qho tseem ceeb kom ua raws li cov khoom lag luam cov txheej txheem thiab siv cov tshuaj tsim nyog kom ua tiav cov txiaj ntsig xav tau. Kev Cia Cov Neeg Khawm yuav tsum tau txiav txim siab los tswj hwm qhov zoo thiab ua tau zoo ntawm cov hmoov.
