I-Redispersible Polymer Powder (RDP)yinxalenye ebalulekileyo yokongeza kwishishini lokwakha kwaye isetyenziswa ngokubanzi kwizinto zokwakha ezahlukeneyo, ngakumbi ukuguqulwa kwe-samente-based, i-gypsum-based kunye nezinye izinto zokwakha ezinomgubo owomileyo. . Ingumgubo oguqulelwe kwi-latex esekelwe emanzini (i-polymer emulsion) ngokusebenzisa inkqubo yokumisa i-spray kwaye inokuphinda iphinde iphinde iphinde ihlaziywe ngamanzi.
1. Ukuphucula amandla okudibanisa
I-latex powder enokuphinda ikwazi ukunyusa ukunamathela kwezinto zokwakha, ngakumbi iimbumba zesamente kunye ne-gypsum mortars. Xa idibaniswe nesamente okanye ezinye izinto ezingaphiliyo, inokwenza ifilimu ethile yepolymer, enegunya eliqinileyo elinobumbano olunobume be-substrate, ngaloo ndlela iphucula kakhulu amandla okudibanisa kwengubo okanye udaka. Ngokukodwa, udaka lodaka lunokubambelela ngokuqinileyo kwimigangatho efana ne-masonry kunye nekhonkrithi, ukunciphisa ukwenzeka kwe-spalling kunye nokuqhekeka.
2. Ukuphucula ukuxhathisa kokuqhekeka
Ukongeza i-latex powder enokuphinda ihlakazwe kwidaka lesamente kunye nezinye izinto zokwakha kunokuphucula ngokufanelekileyo ukuxhathisa kwabo ukuqhekeka. Iinqununu ze-polymer kwi-latex powder zenza isakhiwo senethiwekhi kwi-samente, enokuthi yenze isigaba sokuqinisa ngaphakathi kwezinto eziphathekayo, ngaloo ndlela iphucula ukuchasana nokuqhekeka kwezinto. Kulwakhiwo olungqingqwa okanye ubushushu obuphezulu kunye nemekobume eyomileyo, ukwenzeka kweentanda yingxaki eqhelekileyo, kwaye ukongeza i-RDP kunokunciphisa ngempumelelo ukwenzeka kwale meko.
3. Ukuphucula ukuguquguquka
Xa udaka lwesamente okanye ezinye izinto zomgubo owomileyo zidibana nokutshintsha kweqondo lobushushu, ziya kuncipha okanye zande ngenxa yokwandiswa kwe-thermal coefficients ezahlukeneyo, okukhokelela ekuqhekekeni okanye kwi-shelling yezinto. I-powder ye-latex ye-redispersible inokunyusa ukuguquguquka kwezinto eziphathekayo, ukuvumela izinto zokwakha ukuba zilungelelanise ngcono kwi-deformation xa zidibana nokutshintsha kweqondo lokushisa, ukunciphisa amathuba okuqhekeka. I-polymer eyongeziweyo inomlinganiselo othile we-elasticity, evumela udaka okanye i-coating ukuba ihlangabezane ngcono noxinzelelo lwangaphandle.
4. Ukuphucula ukunganyangeki kwamanzi kunye nokungangeni
I-latex powder ye-redispersible inesiphumo esithile sokungena kwamanzi kwaye inokuphucula ngokufanelekileyo ukunyanzeliswa kwamanzi kunye nokunyanzeliswa kodaka lwesamente. Ifilimu ye-polymer eyenziwe ngumgubo we-latex kwinkqubo ye-samente ine-permeability encinci yamanzi kwaye ngoko inokuphucula kakhulu ukusebenza komdaka kumanzi okanye ixesha elide lokubonakaliswa kwamanzi. Oku kubaluleke kakhulu kwipeyinti yangaphandle, iindonga zangaphantsi, amagumbi okuhlambela kunye nezinye iindawo ezixhomekeke ekuvelweni kwamanzi ixesha elide.
5. Ukuphucula iimpawu ezichasene nongcoliseko
I-samente okanye izinto ezisekelwe kwi-plaster-based ziyakwazi ukungcoliswa, ukungcoliswa, okanye ukukhula kwesikhunta ngexesha lokusetyenziswa. Emva kokongeza i-latex powder edibeneyo, i-antifouling layer ingenziwa phezu kwezinto eziphathekayo, ezinokunciphisa ngokufanelekileyo ukunamathela kothuli phezu komhlaba kwaye inqanda ukukhula kwesikhunta kunye neebhaktheriya. Oku akuphuculi kuphela ubuhle bezinto zokwakha kodwa kwandisa ubomi bayo benkonzo.
6. Phucula ukuxhathisa ukunyibilika komkhenkce
Kwiindawo ezibandayo, izinto zokwakha zihlala ziphantsi kwemijikelo yokunyibilika komkhenkce kwaye zithande ukuqhekeka okanye ukuxobuka. Ngokungongeza i-latex powder enokuphinda ihlaziywe, ukuxhatshazwa kwe-freeze-thaw yezinto eziphathekayo kunokuphuculwa kakhulu. Ipolymer kwi powder latex idibanisa kunye neemveliso ze-hydration kwisamente ukuphucula ukuxutywa kwezinto, ukunciphisa ukungena kwamanzi kunye nokwandiswa kwamanzi ngexesha lenkqubo yokunyibilika komkhenkce, ngaloo ndlela kuncitshiswe umonakalo obangelwa ngumjikelo wokunyibilika komkhenkce.
7. Ukuphucula ukusebenza kolwakhiwo
I-latex powder ye-redispersible inokuphucula iimpawu zesicelo sodaka kunye neengubo, okwenza kube lula ukuphatha nokusebenzisa. Ngenxa yokuba i-latex powder inomswakama omhle kunye nokusabalalisa, inokwenza udaka lube ne-fluidity engcono kunye nokusebenza, ukuphepha ukwanda kobunzima bokwakha ngenxa yokomisa ngokugqithisileyo okanye ukunamathela okunganeleyo. Oku akugcini nje ukuphucula ukusebenza kakuhle kolwakhiwo, kodwa kuqinisekisa umgangatho wokwakha.
8. Ukomelezwa kokuqina
Njengoko izinto zokwakha zikhula, ukusebenza kwazo kunokuncipha ngokuthe ngcembe ngenxa yokutshintsha kweemeko zokusingqongileyo. Ukongezwa kwepowder ye-latex enokuchithwa kwakhona kunokunyusa ukuqina kwe-sement mortar okanye ezinye ii-substrates, ngokukodwa xa zijongene nezimo zezulu ezigqithiseleyo, iindawo ezinomswakama kunye nezinye izinto zangaphandle, ukugcina ubomi obude benkonzo. Oku kubaluleke kakhulu kwizakhiwo eziphantsi koxinzelelo lwexesha elide, ezinje ngodonga lwangaphandle, ukulungiswa kweendlela, kunye neebhulorho.
9. Ukuphucula ukusebenza kunye nokuzilungisa
I-latex powder ekwaziyo ukuphinda ikwazi ukuphucula amandla okuziphilisa wemathiriyeli. Xa kwenzeka umonakalo omncinci, izinto eziphathekayo ziyakwazi ukuzilungisa ngokwazo ngeenguqu ezincinci zepolymer, ukunciphisa ukungena kwamanzi kunye nomonakalo obangelwa ukuqhekeka. Ngaphezu koko, inokuphucula ubumbano kunye nokumelana nokuguga kodaka kwaye yandise ixesha layo lokusebenza.
Indima ye-latex powder enokuchithwa kwakhona kwizicelo zokwakha inamacala amaninzi. Ayiphuculi nje kuphela iipropati ezibonakalayo zezinto zokwakha, kodwa kwakhona iphucula ukusebenza kwayo kolwakhiwo, ukuqina kunye nokukhuselwa kwendalo. Ngokuphucula ukusebenza kwimilinganiselo emininzi njengamandla ebhondi, ukunganyangeki kokuqhekeka, ukunganyangeki kwamanzi, ukunganyangeki kongcoliseko, ukumelana nokunyibilika komkhenkce, njl.iRDPibonelela ngamathuba amaninzi kushishino lolwakhiwo, ngakumbi kwiiprojekthi zokwakha ezinemfuno ephezulu kunye neemeko ezingqongileyo ezirhabaxa. okusingqongileyo, inexabiso elisebenzayo elisebenzayo. Kwixesha elizayo, njengoko imfuno yoshishino lolwakhiwo yokusebenza okuphezulu, izinto ezinokuqina okuphezulu zinyuka, amathuba okusebenza kwe-latex powder aphinde abe banzi.
