1. Intangiriro
Inzira ya polystirene yangiza ni ibikoresho bisanzwe bikoreshwa mukubaka inkuta zo hanze.Ihuza ibyiza bya polystirene (EPS) na minisiteri gakondo, itanga ingaruka nziza zo gukingira hamwe nubukanishi.Kugirango turusheho kunoza imikorere yuzuye, cyane cyane kugirango irusheho gukomera, kurwanya ibimena no kubaka, ifu ya redispersible latex (RDP) ikongerwaho.RDP ni polymer emulion muburyo bwa poro ishobora gusubirwamo mumazi.
2. Incamake yifu ya redxersible latex (RDP)
2.1 Ibisobanuro n'imiterere
Ifu ya redispersible latex ni ifu ikozwe na spray yumisha polymer emulsion yabonetse na emulion polymerisation.Irashobora gusubirwamo mumazi kugirango ikore emulisiyo ihamye hamwe na firime nziza kandi ifata neza.RDPs zisanzwe zirimo Ethylene-vinyl acetate copolymer (EVA), acrylate copolymer na styrene-butadiene copolymer (SBR).
2.2 Ibikorwa by'ingenzi
RDP ikoreshwa cyane mubikoresho byubaka kandi ifite imirimo ikurikira:
Kongera imbaraga zifatika: Tanga imikorere myiza yo gufatira hamwe, bigatuma isano iri hagati ya minisiteri na substrate, minisiteri na polystirene.
Kunoza uburyo bwo kurwanya ibice: Kunoza uburyo bwo guhangana na minisiteri ukora firime yoroheje ya polymer.
Kunoza imikorere yubwubatsi: Ongera ubworoherane nubwubatsi bwamazi ya minisiteri, byoroshye gukwirakwizwa nurwego.
Kunoza kurwanya amazi no kurwanya ubukonje: Kongera imbaraga zamazi no kurwanya ubukonje bwa minisiteri.
3. Gukoresha RDP muri polystirene ya insuline
3.1 Kunoza imbaraga zo guhuza
Muri polystirene ibice byokwirinda, gufatira hamwe nibikorwa byingenzi.Kubera ko ibice bya polystirene ubwabyo ari ibikoresho bya hydrophobique, biroroshye kugwa muri matrise ya minisiteri, bikaviramo kunanirwa na sisitemu yo kubika.Nyuma yo kongeramo RDP, firime ya polymer yakozwe muri minisiteri irashobora gutwikira neza ubuso bwa polystirene, bikongera umwanya uhuza hagati yabo na matrise ya minisiteri, kandi bigateza imbere imbaraga zihuza.
3.2
Filime ya polymer yakozwe na RDP ifite imiterere ihindagurika kandi irashobora gukora mesh imbere muri minisiteri kugirango birinde kwaguka.Filime ya polymer irashobora kandi gukuramo imihangayiko iterwa nimbaraga zo hanze, bityo ikarinda neza ibice biterwa no kwaguka kwubushyuhe no kugabanuka cyangwa kugabanuka.
3.3 Kunoza imikorere yubwubatsi
Inzira ya polystirene yerekana insuline ikunda kwibasirwa nabi kandi bigoye gukwirakwira mugihe cyo kubaka.Kwiyongera kwa RDP birashobora guteza imbere cyane imikorere yimikorere ya minisiteri, bigatuma minisiteri yoroshye kubaka no kunoza imikorere yubwubatsi.Byongeye kandi, RDP irashobora kandi kugabanya itandukanyirizo rya minisiteri no gutuma ikwirakwizwa ryibikoresho bya minisiteri riba kimwe.
3.4 Kunoza amazi kurwanya no kuramba
Inzira ya polystirene ikingira ikeneye kugira amazi meza mukoresha igihe kirekire kugirango amazi yimvura atangirika.RDP irashobora gukora hydrophobic layer muri minisiteri ikoresheje imiterere yayo ya firime, ikabuza neza ubuhehere kwinjira muri minisiteri.Byongeye kandi, firime yoroheje itangwa na RDP irashobora kandi kongera imbaraga za minisiteri yo kurwanya ubukonje no gukonjesha no kongera igihe cyumurimo wa minisiteri.
4. Uburyo bwibikorwa
4.1 Ingaruka zo gukora firime
RDP imaze gusubizwa mumazi muri minisiteri, ibice bya polymer bigenda bihurira hamwe kugirango bibe firime ikomeza.Iyi firime irashobora gufunga neza utwobo duto muri minisiteri, ikarinda kwinjiza amazi n’ibintu byangiza, kandi ikongerera imbaraga guhuza ibice.
4.2 Ingaruka nziza yimbere
Mugihe cyo gukomera kwa minisiteri, RDP irashobora kwimukira mumwanya uri hagati ya minisiteri na polystirene kugirango ikore urwego rwimbere.Iyi firime ya polymer ifatanye cyane, ishobora guteza imbere cyane imbaraga zihuza ibice bya polystirene na materique ya minisiteri kandi bikagabanya kubyara ibice byacitse.
4.3
Mugukora imiyoboro ihindagurika imbere muri minisiteri, RDP yongerera ubworoherane bwa minisiteri.Uru rusobe rworoshye rushobora gukwirakwiza imihangayiko yo hanze no kugabanya imihangayiko, bityo bigatera imbaraga zo guhangana no kuramba kwa minisiteri.
5. Ingaruka zo kwiyongera kwa RDP
5.1 Amafaranga yinyongera akwiye
Umubare wa RDP wongeyeho ufite ingaruka zikomeye kumikorere ya polystirene ya insuline.Mubisanzwe, umubare wa RDP wongeyeho uri hagati ya 1-5% yububiko rusange bwa sima.Iyo amafaranga yongeweho aringaniye, irashobora kunoza cyane imbaraga zoguhuza, kurwanya guhangana nibikorwa byubwubatsi.Ariko, kwiyongera cyane birashobora kongera ibiciro kandi bikagira ingaruka kumbaraga nimbaraga zo kwikomeretsa.
5.2 Isano iri hagati yinyongera ninyongera
Imbaraga zinguzanyo: Mugihe umubare wa RDP wongeyeho wiyongera, imbaraga zo guhuza za minisiteri zigenda ziyongera buhoro buhoro, ariko nyuma yo kugera ku kigero runaka, ingaruka zo kurushaho kongera amafaranga yongeweho mukuzamura imbaraga zubufatanye ni nke.
Kurwanya kumeneka: Umubare ukwiye wa RDP urashobora kunoza cyane guhangana na minisiteri, kandi bike cyangwa byinshi byongeweho bishobora kugira ingaruka nziza.
Imikorere yubwubatsi: RDP itezimbere kandi ikora neza ya minisiteri, ariko kwiyongera cyane bizatera minisiteri guhinduka cyane, bidafasha mubikorwa byubwubatsi.
6. Gushyira mu bikorwa n'ingaruka
6.1 Urubanza rwubwubatsi
Mu mishinga ifatika, RDP ikoreshwa cyane muri sisitemu yo kubika hanze (EIFS), minisiteri ya pompe na minisiteri.Kurugero, mubikorwa byo kubaka urukuta rwo hanze rwubatswe runini rwubucuruzi, wongeyeho 3% RDP mumashanyarazi ya polystirene, imikorere yubwubatsi ningaruka zo gukingira za minisiteri byateye imbere cyane, kandi ibyago byo guturika mugihe cyubwubatsi byari yagabanutse neza.
6.2 Kugenzura ubushakashatsi
Ubushakashatsi bwakozwe bwerekanye ko polystirene yangiza insina ya minisiteri hiyongereyeho RDP yagize iterambere ryinshi mububasha bwo guhuza imbaraga, imbaraga zo kwikomeretsa no kurwanya imishitsi muminsi 28.Ugereranije nicyitegererezo cyo kugenzura nta RDP, imbaraga zo guhuza ingero zongerewe na RDP ziyongereyeho 30-50% naho kurwanya ibice byiyongereyeho 40-60%.
Redispersible latex powder (RDP) ifite agaciro gakomeye mugukoresha muri polystirene.Itezimbere neza imikorere yuzuye ya minisiteri yimbaraga mukwongerera imbaraga guhuza, kunoza imirwanyasuri, kunoza imikorere yubwubatsi, no kunoza amazi no kuramba.Mubikorwa bifatika, iyongerwaho rikwiye rya RDP irashobora kuzamura cyane ituze nigihe kirekire cya sisitemu yo gukumira, itanga ingwate yingenzi yo kubaka ingufu n’umutekano w’imiterere.
