Recispersible polymer hmoov (RDP) yog cov hmoov tsim los ntawm cov tshuaj tsuag kom qhuav ntawm polymer emulsion. Nws tuaj yeem raug muab rov qab rau hauv cov dej emulsion hauv dej los rov qab nws cov khoom qub, yog li nws tau siv dav hauv kev tsim kho kev tsim kho thiab lwm yam khoom muaj kev lag luam. Kab lus no yuav tshawb txog ntau cov kev siv ntawm refispersible polymer hmoov nyob rau hauv kev lag luam khoom lag luam, suav nrog cov ntaub ntawv tsim tsev, cov nplaum, cov tshuaj nplaum thiab cov caulking cov neeg sawv cev.
1. Lub tsev ua haujlwm
Daim ntawv thov ntawm Redispersible polymer hmoov nyob rau hauv cov ntaub ntawv tsim tsev yog ib daim teb ntau tshaj plaws. Nws tuaj yeem txhim kho kev ua tau zoo ntawm cov tshuaj khib sib xyaw, xws li txhim kho kev sib koom ua ke lub zog, tawg ua kom tsis taus thiab hloov tau. Nyob rau sab nrauv phab ntsa rwb thaiv tsev ua haujlwm, RDP, yog txhim kho cov txheej txheej hauv tsev thiab cuam tshuam thiab txuas ntxiv kev pabcuam lub neej ntawm lub tsev. Tsis tas li ntawd, RDP tseem tuaj yeem txhim kho cov dej tsis kam thiab huab cua tsis kam ntawm cov ntaub ntawv caas-based, kom nws tseem tuaj yeem ua kom muaj kev ua tau zoo hauv chaw hnyav.
RDP tseem dav siv nyob rau hauv tus kheej-theem pem teb cov ntaub ntawv. Kev ntsuas tus kheej txoj kev xav tau cov dej zoo thiab muaj zog. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho kev tsim kho cov khoom siv ntawm tus kheej, txhim kho lawv lub zog compressive thiab yooj yim dua thiab yog li ua kom lub tiaj tiaj thiab ruaj khov ntawm hauv av. Nyob rau hauv cov nplais nplaum, daim ntawv thov ntawm RDP tseem yog qhov tseem ceeb. Nws tuaj yeem txhim kho thawj cov nplaum thiab lub zog kawg ntawm cov nplais nplaum, nce los tiv thaiv cov khoom uas quav, thiab yog li ua kom cov vuas khov kho thiab yooj yim ntawm kev tsim kho.
2. Cov txujces
Cov hnab yas liab uas polymer tseem muaj dav hauv cov nplaum, tshwj xeeb tshaj yog nyob rau hauv cov ntoo kua nplaum thiab cov ntawv nplaum. Tsoos ntoo cov kua nplaum feem ntau ua cov dej ntws tom qab dej yaj, thaum RDP tuaj yeem txhim kho cov nplaum thiab nthuav lawv lub neej. Nyob rau tib lub sijhawm, RDP kuj tseem tuaj yeem txhim kho cov khoom sib raug zoo ntawm cov nplaum, xws li cov ntaub nplaum, cov ntaub nplaum thiab lwm yam los txhawb lawv cov kev siv zog thiab siv zog.
3. Tsho tiv thaiv
Nyob rau hauv cov txheej txheej kev lag luam, cov hmoov polymer polymer muaj peev xwm txhim kho kev ua tau zoo ntawm kev ua tau zoo. RDP tuaj yeem txhim kho cov nplaum ntawm txheej thiab ua rau lawv muaj ntau cov hnav-tiv taus thiab dej tsis taus. Tsis tas li ntawd, RDP tseem tuaj yeem txhim kho qhov yooj ntawm kev ua kom yooj yim thiab txo qhov kev pheej hmoo ntawm kev tawg. Cov cuab yeej no ua rau RDP ib qho kev ntxiv ntxiv rau kev ua haujlwm sab nrauv phab ntsa sab nrauv, lub tsho hluav taws xob thiab cov dej sov waterproof. Cov hmoov nplej polymer kuj tseem tuaj yeem siv los ua cov khoom ntxiv hauv cov ris ua kom tsis kam thiab tshuaj lom neeg tiv thaiv nws lub neej.
Daim ntawv thov ntawm RDP hauv cov hmoov txheej tseem muaj kev nce ntxiv. Piv nrog cov kev ua yeeb yaj kiab ua yeeb yam, hmoov txheej txheem yog ib puag ncig zoo nkauj, yog li lawv tau txais kev pab them zoo thiab adhesion zoo ntawm cov sib txawv. Qhov no ua rau RDP muaj txoj haujlwm tseem ceeb hauv kev ua lag luam ib puag ncig ua lag luam.
4. Foob
Daim ntawv thov ntawm Redispersible polymer hmoov nyob rau hauv cov ntawv foob nyob hauv kev foob tuaj yeem txhim kho nws cov kev ua tau zoo. Tsoos ib txwm nrib pleb feem ntau tawg vim tias qhov kev ua kom huv, tab sis tom qab ntxiv RDP, muab cov kev pheej hmoo ntxiv, txo qis kev pheej hmoo ntawm kev tawg. Ntxiv rau, RDP kuj tseem tuaj yeem txhim kho cov kev sib raug zoo ntawm lub zog thiab dej tsis kam ntawm cov foob pob, kom nws tseem tuaj yeem ua kom muaj kev ua tau zoo hauv ib puag ncig. Qhov no yog qhov tshwj xeeb tshaj yog qhov tseem ceeb rau kev siv cov av noo hauv thaj chaw muaj dej hiav txwv zoo li chav dej thiab chav ua noj.
Nyob rau hauv kev ua tau zoo caulking cov neeg sawv cev, RDP tseem tuaj yeem muab cov khoom zoo tshaj plaws rau lawv, kom sawv daws yuav nyob twj ywm zoo nkauj thiab huv thaum siv sijhawm ntev. Qhov no ua rau RDP dav siv hauv kev kho kom zoo nkauj kom zoo nkauj.
5. Lwm cov ntawv thov kev lag luam
Ntxiv nrog rau cov chaw thov saum toj no, cov neeg them nyiaj polymer muaj kuj tau pom nws cov kev sib txawv hauv ntau lwm cov chaw muaj kev lag luam. Piv txwv li, hauv kev lag luam textile, RDP tuaj yeem siv los ua cov ntaub npuag kom txhim kho kev softness los txhim kho lub mos mos thiab kev ntxuav cov ntaub. Nyob rau hauv lub papermaking kev lag luam, RDP tuaj yeem txhim kho lub zog thiab cov khoom ntawm cov khoom thiab txhim kho cov khoom siv luam ntawv. Hauv kev lag luam plastics, RDP tuaj yeem siv ua lub yas yas thiab hloov kho kom txhim kho qhov hloov tau thiab ruaj khov ntawm cov yas.
Vim nws cov kev ua tau zoo heev thiab kev siv hluav taws xob dav dav, cov hmoov polymer muaj zog tau dhau los ua qhov tsis tseem ceeb thiab cov khoom tseem ceeb hauv kev tsim cov khoom lag luam niaj hnub. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nthuav dav txuas ntxiv ntawm cov ntawv thov, cov ntawv thov kev cia siab ntawm RDP hauv kev lag luam yuav nthuav dav.
