I-RDP yePolymer Powder yokuLungisa iiMorta: Uthelekiso olunyanisekileyo vs. SBR & Ii-acrylics

I-RDP yePolymer Powder yokuLungisa iiNdawo zodaka ayingomlingo-kodwa isondele

Makhe sijonge kuyo. Ukuba uchaza okanye udibanisa iimbumba zokulungisa, I-RDP ipolymer powder yokulungisa iimbumba kaninzi sesona sicombululo somxube owomileyo sokuncamathela kunye nokuguquguquka. Isingxi. Ayingomdlalo wodwa edolophini, kwaye inorhwebo lokwenyani. Sichithe amashumi eminyaka sibukele abafana besonakalisa ibhetshi elungileyo ngokuphatha iRDP njengothuli lomlingo. Ayiyo. Kodwa xa uyiqonda, awuyi kuphinda ubuyele kwimixube engalungiswanga ukulungiswa okuncinci.

Sithetha ngepolymer powder ephinda ihlakazwe. Yintlaka ye-thermoplastic-idla ngokuba yi-vinyl acetate ethylene (INYAWO) okanye i-copolymer-spray-yomisiwe kwi-carrier ecocekileyo. Yigalele kudaka olomileyo. Yongeza amanzi. Iingqungquthela zepowder ziphinda zihlakazeke kwifilimu ye-latex ngexesha lokuhamba. Loo filimu iiblorho iintanda, iibhondi kwikhonkrithi endala, kwaye ihleka ukungena kwamanzi. Ingcamango elula. Ukubulawa ngenkohlakalo ukuba ufumana idosi engalunganga.

1. I-RDP vs. SBR (Irabha ye-Styrene-Butadiene) vs. Iemulsions ze-Acrylic

Le yingxoxo enkulu kuyo yonke indawo yomsebenzi. Yeyiphi imodyuli yepolymer eyinkosi? Impendulo? Kuxhomekeke kuwe usetyenziso lwehlabathi lokwenyani. Hayi idatha yaselebhu. Nanku uqhekeko sifunde kabuhlungu.

1.1. I-SBR Latex (UMlindi Omdala)

I-SBR lulwelo. Ixabiso eliphantsi. Ibikho ukusukela ngeminyaka yee-1950. Abantu abaninzi bakudala bafunga ngayo.

• IiPros: Amandla ebhondi agqwesileyo kwi-substrates ezifumileyo. Ukuguquguquka okuphezulu. Iindleko eziphantsi ngegaloni nganye.
• Ububi: Kufuneka uyixube kwisiza (ukuphatha ulwelo yintlungu). Iyanuka (ivumba le-ammonia). Ayisiyonxalenye yomxube owomileyo. Yisebenzise ngokugqithisileyo, kwaye ufumana irabha, udaka olubuthathaka olungaze lunyange ngokufanelekileyo.
• Ukuthatha kwethu: Ilungile kumthamo omkhulu, umsebenzi wesite-batched apho unempompo yolwelo kunye nemaski yokungenisa umoya. Kuyoyikeka kwiindonga zokulungisa iingxowa zangaphambili.

1.2. Iemulsions ze-Acrylic (Umjikijeli)

I-Acrylics nayo ilulwelo. Banikezela ngcono ukuchasana kwe-UV kune-SBR. Zizo eziya kwi-overlays ezincinci kunye ne-self-leveling toppings.

• IiPros: Uzinzo olugqwesileyo lombala (ayikho tyheli). Ukubambelela kakuhle kwintsimbi kunye nekhonkrithi endala. IiVOC eziphantsi.
• Ububi: Iyabiza. Unovelwano xa umkhenkce (ulwelo lungonakala). Ifuna ukulondolozwa okuthe ngqo kwitoti ukunqanda ukonakaliswa. Ayifanelekanga kwizityalo ezixubeneyo ezomileyo.
• Ukuthatha kwethu: Ifanelekile kwizinto ezihonjisiweyo zekhonkrithi. I-Overkill yokulungiswa kodaka lwesakhiwo apho ufuna amandla aphezulu kwangoko.

1.3. RDP Polymer Powder (I-Dry-Mix Winner)

Kulapho I-RDP ipolymer powder yokulungisa iimbumba liyakhazimla. Ngumgubo. Ingena engxoweni kumzi-mveliso. Umakhi wongeza amanzi kuphela kwisiza.

• IiPros: Uzinzo lokugcina olugqwesileyo (yomile, indawo yokugcina impahla epholileyo). Akukho miba yokukhenkceza engxoweni. Ukusebenza okuqikelelweyo-ibhetshi ukuya kwibhetshi ukungaguquguquki kuphezulu. Yehlisa imodyuli ye-elasticity, nto leyo ebaluleke kakhulu ekuvalelekeni kweebhulorho ekulungisweni kweziziba. Yandisa ixesha lokuvula kakhulu.
• Ububi: Uhlawulela uncedo (Ibiza kakhulu kunolwelo lwe-SBR ngeyunithi nganye yezinto eziqinileyo zepholima). Inokuthi i-agglomerate ukuba igcinwe ngokungafanelekanga (jonga ukuphatha ngezantsi). Inokunciphisa amandla oxinzelelo kwiidosi eziphezulu.
• Ukuthatha kwethu (20+ iminyaka): Kuba naluphi na ulungiso oluveliswe ngumzi-mveliso wodaka-oluthe nkqo, amabala axwesileyo, ubuyiselo lwekhonkrithi-RDP lukhetho oluchanekileyo. Isingxi.

2. Isebenza njani iRDP Film Formation (Inzululwazi esiyisebenzisa ngokwenene)

Siyithiyile i-theory fluff. Kodwa kufuneka uqonde le ndlela enye: ukwenziwa kwefilimu.

Xa uxuba umgubo weRDP emanzini, amasuntswana adumba kwaye aqale ukudibanisa. Njengoko isamente i-hydrates kunye namanzi adliwe, amasuntswana epolymer atyhala kunye. Badibanisa kwifilimu eqhubekayo ejikeleza i-sement hydrates kunye ne-aggregates. Le filimu yinto ekunika loo nto ukomelela kokuqina kwebhondi kwaye amandla okuguquguquka.

Inqaku elibalulekileyo: Lo mboniso bhanyabhanya wenzeka kuphela ukuba iqondo lobushushu lingaphezulu koBuncinci boBubushushu boBume beFilimu (I-MFFT). Ngokuqhelekileyo ngu-5°C ukuya kwi-10°C. Ukuba kubanda kakhulu (umsebenzi wasebusika eCanada, nabani na?), i-polymer ayizange yenze ifilimu. Ufumana ubumdaka obunzima. Iikontraka ezininzi zakufunda kabuhlungu oku.

3. Iipropati zoomatshini: URhwebo lokwenyani

Sibuzwa ngalo lonke ixesha: “Ngaba i-RDP yenza udaka lwam lomelele?” Impendulo i-nuanced.

• Amandla e-Flexural: Iyahamba phezulu. Ngokubalulekileyo. Ifilimu yepolymer isebenza njenge-micro-reinforcement. Lindela a 30-50% ukwanda phezu kodaka olungalungiswanga.
• Ukomelela kweBond: Iyahamba phezulu. Esi sesona sizathu siphambili sisisebenzisa. Ukunamathela kwikhonkrithi endala, intsimbi, kwaye i-masonry iphuculwe ngokumangalisayo.
• Ukuchasa impembelelo: Iyahamba phezulu. Ipolymer ifunxa amandla. Ilungele ukulungiswa komgangatho kwiindawo zokugcina iimpahla.
• Amandla acinezelayo: Iyahamba phantsi (kwiidosi eziqhelekileyo). Olu lurhwebo. Ifilimu ye-polymer ibuthathaka phantsi koxinzelelo olucocekileyo kune-matrix eqinile yesamente. Awukwazi ukuba bhetyebhetye, high-bond udaka kwaye kwakhona ulindele 8,000 psi amandla oxinzelelo. Yifiziksi. Ulawulo lwedosi yinto yonke.

4. Umthamo: Indawo yeGoldilocks

I-RDP encinci kakhulu, kwaye awufumani nzuzo. Kaninzi, kwaye udaka lwakho lujika lube bhetyebhetye, I-putty ebuthakathaka eya kukhwela phantsi komthwalo.

Kumava ethu, idosi eqhelekileyo ye I-RDP ipolymer powder yokulungisa iimbumba iphakathi 2% kwaye 6% ngobunzima besamente.

• 2-3%: Ukuxhathisa amanzi okusisiseko kunye nokubambelela okuthile. Eyona nto ingcono kwi-non-structural patching.
• 4-5%: Ilungele ukulungiswa kwezakhiwo ezininzi. Ibhalansi elungileyo yamandla e-flexural kunye nebhondi. Lo ngumgangatho we-EN 1504-3 iklasi ye-R3 kunye ne-R4 yodaka.
• 6%+: Ukuguquguquka okuphezulu, kodwa lindela a 15-20% yehla amandla acinezelayo. Sebenzisa kuphela ukuqhekeka kwe-crack-bridging overlays okanye iileya ezibhityileyo ezixhomekeke kwintshukumo ye-thermal.

Sisoloko sibaxelela oogxa bethu: Musa ukuleqa amandla ebhondi ngepolymer egqithisileyo. Phucula ulungiselelo lwakho lwe-substrate endaweni yoko. A ecocekileyo, ifumile, umphezulu orhabaxa uxabisa ngaphezulu 2% i-RDP eyongezelelweyo.

5. Isicelo: Ukulungiswa kweNqanaba eliNcinci, Patch Mortars, kunye noKwaleka

Kulapho udaka olulawulwa yi-RDP longamele ngokwenene.

• Ukulungiswa kwe-Thin-layer (ngaphantsi kwe-10mm): Udaka olungalungiswanga luyacutheka kwaye luqhekeke. I-RDP-modified mortars ziye zanciphisa ukushwabana kunye nokunamathela okugqwesileyo. Ikuphela kwesisombululo esithembekileyo samabala anentsiba.
• Ukubuyiselwa kwekhonkrithi (IN 1504): Uninzi lweendonga ezithobela umgangatho zixhomekeke kwi-RDP kumandla afunekayo ebhondi kunye nokumelana ne-carbonation.
• Izigqubuthelo (iidekhi zokupaka, iibhulorho): Imodyuli encitshisiweyo ye-elasticity (ukuqina okuphantsi) ivumela isigqubuthelo ukuba sihambe ne-substrate ngaphandle kokunciphisa.

Abasebenzisi abaninzi kwiReddit baye baxela ukuba udaka olusekwe kwi-RDP kulula phinda usebenze. Unokufaka isiqwenga, lungisa umphezulu we 15-20 imizuzu, kwaye ayiqini ngokukhawuleza njengemixube yesamente ecocekileyo. Ixesha elivulekileyo liyinzuzo enkulu ebonakalayo.

6. Ukugcinwa kunye nokuphatha: Ziphephe iiClumps

Nantsi imfihlo emdaka: Umgubo weRDP uthanda ukufuma. Yi-hygroscopic. Ukuba uvula ibhegi kwaye uyishiye kwindawo yokugcina impahla efumileyo kangangenyanga, amasuntswana agglomerate. Ziba ngamaso amancinane aqinileyo angaze aphinde asasazeke ngokufanelekileyo.

Imithetho yokugcina esiphila ngayo:

• Gcina iingxowa zivaliwe de zisetyenziswe.
• Gcina kwiqondo lobushushu lendawo (15-25°C ifanelekile). Akukho magumbi angaphantsi ashushu.
• Jikelezisa isitokhwe. Okokuqala kwi, kuqala ngaphandle. I-RDP inobomi obuhlala kwishelufu malunga 12 iinyanga ukusuka kwimveliso.
• Ukuba ufumana i-agglomerates kumxube, udaka lwakho luya kuba buthathaka. Lahla ibhetshi.

7. Imigangatho: IN 1504 kunye ne-ASTM C190

Uya kubona ezi zishunqulelo kumaphepha edatha. Nantsi into abayithethayo ngodaka lwakho lokulungisa.

• IN 1504-3: Umgangatho waseYurophu wodaka lwezakhiwo kunye nolungekho lwesakhiwo. Iklasi ye-R3 (engeyiyo yolwakhiwo) kunye ne-R4 (ulwakhiwo). Zombini zifuna ukuguqulwa kwepolymer ukuze kuphumelele uvavanyo lwamandla ebhondi (>1.5 MPa ngeR4). I-RDP sisisombululo esiqhelekileyo.
• I-ASTM C190: Indlela yovavanyo esemgangathweni yokuqina kokuqina kwebhondi. Udaka olulungisiweyo olulungileyo lwe-RDP luya kufezekiswa 2.0 I-MPa okanye ngaphezulu kwi-substrate yekhonkrithi elungiselelwe ngokufanelekileyo.

Ukuba i-spec sheet yakho ithi “Udibana ne-EN 1504-3 Udidi R4,” ungathemba ukuba umenzi wefomula uyaqonda I-RDP ipolymer powder yokulungisa iimbumba.

8. Ingcebiso yokugqibela: Kufuneka wenze ntoni ngokulandelayo?

Sibone iiprojekthi ezininzi kakhulu zisilela kuba umntu ubambe eyona polymer yolwelo inexabiso eliphantsi (SBR) kwivenkile yehardware, ixube kakubi, kwaye i-patch yaphela ngonyaka.

Ukuba wenza okanye uchaza iimbumba zokulungisa ukuze zisetyenziswe ngobuchule, khetha ukwakheka komxube owomileyo kunye nomgangatho we-RDP powder. Ikunika uqikelelo, lula ukusetyenziswa, kunye nokusebenza okuqinisekisiweyo phantsi kwe-EN 1504 okanye imigangatho ye-ASTM.

Amanyathelo alandelayo kuwe:

• Ukuba ungumyili, vavanya udaka lwakho kwi 4% I-RDP ngokobunzima besamente. Thelekisa iresiphi yakho yangoku ye-SBR. Siyathembisa ukuba amandla ebhondi ayakulingana okanye angcono, kwaye ulungiselelo luya kuba lula.
• Ukuba ungunokontraka, cela umthengisi wakho ngepesenti yeRDP engxoweni. Ukuba abazi, hamb 'umshiye.
• Ukuba ungumnikazi we-asethi, cacisa uNYE 1504-3 Udaka lwe-R4 yeklasi ene-polymer modifier eqinisekisiweyo. Ungavumeli nabani na athathe indawo ye-acrylic engamanzi ngaphandle kovavanyo olungqongqo.

Lo ngumbono wokwenyani wehlabathi I-RDP ipolymer powder yokulungisa iimbumba. Akukho fluff yokuthengisa. Kuphela urhwebo kunye nezigqibo ezibalulekileyo. Hamba uyokwenza ulungiso oluhlala luhleli.
