1. Isingeniso
I-polystyrene particle insulation mortar iyinto evame ukusetshenziselwa ukwakha ukufakwa odongeni kwangaphandle. Ihlanganisa izinzuzo zezinhlayiya ze-polystyrene (i-EPS) nodaka lwendabuko, ihlinzeka ngomphumela omuhle wokufakelwa kanye nezakhiwo zemishini. Ukuze kuqhutshekwe nokuthuthukisa ukusebenza kwayo okuphelele, ikakhulukazi ukuthuthukisa ukunamathela kwayo, ukumelana nokuqhekeka nokusebenza kokwakhiwa, i-latex powder (RDP) ekhishwa kabusha i-redispersible (RDP) ivame ukungezwa. I-RDP iyi-emulsion ye-polymer efomini eliyimpushana engaphinde ihlakazwe emanzini.
2. Uhlolojikelele lwempushana ye-latex ehlakazeka kabusha (RDP)
2.1 Incazelo kanye nezakhiwo
Redispersible latex powder iyimpushana eyenziwe ngokufutha ngokumisa i-emulsion ye-polymer etholwe yi-emulsion polymerization. Ingaphinde ihlakazwe emanzini ukuze yenze i-emulsion ezinzile enezakhiwo ezinhle zefilimu kanye nokunamathela. Ama-RDP ajwayelekile afaka i-ethylene-vinyl acetate copolymer (EVA), i-acrylate copolymer ne-styrene-butadiene copolymer (SBR).
2.2 Imisebenzi esemqoka
I-RDP isetshenziswa kakhulu ezintweni zokwakha futhi inemisebenzi elandelayo:
Thuthukisa ukunamathela: Nikeza ukusebenza okuhle kakhulu kokunamathela, okwenza isibopho phakathi kodaka ne-substrate, udaka kanye nezinhlayiya ze-polystyrene kuqine.
Thuthukisa ukumelana nokuqhekeka: Thuthukisa ukumelana nokuqhekeka kodaka ngokwenza ifilimu ye-polymer eguquguqukayo.
Thuthukisa ukusebenza kokwakha: Khulisa ukuguquguquka nokuguquguquka kokwakhiwa kodaka, ukusabalalisa kalula kanye nezinga.
Thuthukisa ukumelana namanzi kanye nokumelana nokuncibilika: Thuthukisa ukumelana namanzi kanye nokumelana nomjikelezo wokuncibilika kodaka.
3. Ukusetshenziswa kwe-RDP odakeni lwezinhlayiyana ze-polystyrene
3.1 Thuthukisa amandla okuxhumana
Ku-polystyrene particle insulation mortar, ukunamathela kuwumsebenzi obalulekile. Njengoba izinhlayiya ze-polystyrene ngokwazo ziyizinto ze-hydrophobic, kulula ukuwa kusuka ku-matrix yodaka, okuholela ekuhlulekeni kwesistimu yokushisa. Ngemva kokwengeza i-RDP, ifilimu ye-polymer eyakhiwe odakeni ingavala ngokuphumelelayo ubuso bezinhlayiya ze-polystyrene, ikhulise indawo yokubopha phakathi kwazo kanye ne-matrix yodaka, futhi ithuthukise amandla okubopha okuhlangene.
3.2 Ukumelana nokuqhekeka okuthuthukisiwe
Ifilimu ye-polymer eyakhiwe yi-RDP inokuguquguquka okuphezulu futhi ingakha isakhiwo se-mesh ngaphakathi kodaka ukuvimbela ukwanda kwemifantu. Ifilimu ye-polymer ingakwazi futhi ukumunca ukucindezeleka okukhiqizwa amandla angaphandle, ngaleyo ndlela ivimbele ngokuphumelelayo imifantu ebangelwa ukwanda okushisayo nokufinyela noma ukuncipha.
3.3 Ukusebenza ngcono kwezokwakha
I-polystyrene particle insulation mortar ijwayele ukungabi namanzi kahle kanye nobunzima bokusabalalisa ngesikhathi sokwakhiwa. Ukwengezwa kwe-RDP kungathuthukisa kakhulu uketshezi nokusebenza kodaka, kwenze udaka lwakhiwe kalula futhi kuthuthukise ukusebenza kahle kokwakhiwa. Ngaphezu kwalokho, i-RDP nayo inganciphisa ukuhlukaniswa kodaka futhi yenze ukusatshalaliswa kwezingxenye zodaka kufane.
3.4 Ukwenza ngcono ukumelana kwamanzi nokuqina
Udaka lwezinhlayiyana ze-polystyrene ludinga ukumelana kahle namanzi uma lusetshenziswa isikhathi eside ukuze luvimbele amanzi emvula ekuguguleni ungqimba lokufakwa kwamanzi. I-RDP ingenza ungqimba lwe-hydrophobic odakeni ngokusebenzisa izici zayo zokwenza ifilimu, ukuvimbela ngempumelelo umswakama ukuthi ungangeni osikeni. Ngaphezu kwalokho, ifilimu eguquguqukayo ehlinzekwa yi-RDP ingase futhi ithuthukise izakhiwo zodaka zokunqanda ukuqhwa kanye nokuncibilika futhi inwebe impilo yesevisi yodaka lokufakelwa.
4. Indlela yokwenza
4.1 Umphumela wokwenza ifilimu
Ngemva kokuba i-RDP iphinde yahlakazwa emanzini odakeni, izinhlayiya ze-polymer kancane kancane zihlangana zibe yinto eyodwa ukuze zenze ifilimu ye-polymer eqhubekayo. Le filimu ingavala ngokuphumelelayo ama-pores amancane odaka, ivimbele ukungena komswakama nezinto eziyingozi, futhi ithuthukise amandla okubopha phakathi kwezinhlayiya.
4.2 Umphumela othuthukisiwe wokusebenzelana
Phakathi nenqubo yokuqina yodaka, i-RDP ingathuthela esibonakalayo phakathi kodaka kanye nezinhlayiya ze-polystyrene ukuze zakhe isendlalelo esibonakalayo. Le filimu ye-polymer inokunamathela okuqinile, okungathuthukisa kakhulu amandla okubopha phakathi kwezinhlayiya ze-polystyrene kanye ne-matrix yodaka futhi kunciphise ukukhiqizwa kokuqhekeka kwesixhumi esibonakalayo.
4.3 Ukuvumelana nezimo okuthuthukisiwe
Ngokwenza uhlaka lwenethiwekhi oluguquguqukayo ngaphakathi kodaka, i-RDP inyusa ukuguquguquka okuphelele kodaka. Le nethiwekhi eguquguqukayo ingahlakaza ukucindezeleka kwangaphandle futhi inciphise ukugxila kokucindezeleka, ngaleyo ndlela ithuthukise ukumelana nokuqhekeka nokuqina kodaka.
5. Umthelela wokwengezwa kwe-RDP
5.1 Inani elingeziwe elifanelekile
Inani le-RDP elengeziwe linomthelela omkhulu ekusebenzeni kwe-polystyrene particle insulation mortar. Ngokuvamile, inani le-RDP elengeziwe liphakathi kuka-1-5% wesamba sesisindo sezinto zikasimende. Uma inani elingeziwe lilinganiselwe, lingathuthukisa kakhulu amandla okubopha, ukumelana nokuqhekeka nokusebenza kokwakhiwa kodaka. Nokho, ukwengeza ngokweqile kungase kwenyuse izindleko futhi kuthinte ubulukhuni namandla acindezelayo odaka.
5.2 Ubudlelwano phakathi kwenani elengeziwe kanye nokusebenza
Amandla ebhondi: Njengoba inani le-RDP elengeziwe likhula, amandla okubopha osimende akhula kancane kancane, kodwa ngemva kokufinyelela ingxenye ethile, umphumela wokwandisa ngokwengeziwe inani elingeziwe ekuthuthukisweni kwamandla okubopha ulinganiselwe.
Ukumelana nokuqhekeka: Inani elifanele le-RDP lingathuthukisa kakhulu ukumelana nokuqhekeka kodaka, futhi ukungezwa okuncane kakhulu noma okuningi kakhulu kungase kuthinte umphumela wawo omuhle.
Ukusebenza kokwakha: I-RDP ithuthukisa ukuguquguquka nokusebenza kodaka, kodwa ukwengezwa ngokweqile kuzobangela udaka ukuba lube ne-viscous kakhulu, okungahambisani nemisebenzi yokwakha.
6. Ukusebenza okusebenzayo kanye nomphumela
6.1 Icala lokwakha
Kumaphrojekthi wangempela, i-RDP isetshenziswa kakhulu ezinhlelweni zokufakelwa kwangaphandle (EIFS), udaka olukhonkolo kanye nodaka olubophayo. Isibonelo, ekwakhiweni kodonga lwangaphandle lwesakhiwo esikhulu sezentengiselwano, ngokwengeza i-RDP engu-3% ku-polystyrene particle insulation mortar, ukusebenza kokwakhiwa kanye nomphumela wokufakelwa kodaka kwathuthukiswa kakhulu, futhi ingozi yokuqhekeka ngesikhathi senqubo yokwakha yathuthukiswa kakhulu. kuncishiswe ngempumelelo.
6.2 Ukuqinisekisa kokuhlola
Ucwaningo lokuhlola lubonise ukuthi i-polystyrene particle insulation mortar ngokungezwa kwe-RDP ibe nokuthuthuka okuphawulekayo emandleni okubopha, amandla okucindezela kanye nokumelana nokuqhekeka ezinsukwini ezingu-28. Uma kuqhathaniswa namasampula okulawula ngaphandle kwe-RDP, amandla okubopha amasampula e-RDP angezwe ngo-30-50% futhi ukumelana nokuqhekeka kukhuphuke ngo-40-60%.
Redispersible latex powder (RDP) inenani elibalulekile lesicelo ku-polystyrene particle insulation mortar. Ithuthukisa ngempumelelo ukusebenza okuphelele kwe-insulation mortar ngokuthuthukisa amandla okubopha, ukuthuthukisa ukumelana nokuqhekeka, ukuthuthukisa ukusebenza kokwakhiwa, nokuthuthukisa ukumelana kwamanzi nokuqina. Ezisetshenziswa ezingokoqobo, ukungezwa okufanele kwe-RDP kungathuthukisa kakhulu ukuzinza nokuqina kwesistimu yokufaka ugesi, kunikeze isiqinisekiso esibalulekile sokwakha ukongiwa kwamandla kanye nokuphepha kwesakhiwo.
