Indima kaokuphinde kuhlakazekei-polymerimpuphuku-putty powder: inokunamathela okuqinile kanye nezakhiwo zemishini, ukungangeni manzi okuvelele, ukungena kwamanzi, kanye nokumelana okuhle kakhulu kwe-alkali kanye nokumelana nokuguguleka, futhi ingathuthukisa ukugcinwa kwamanzi futhi yandise isikhathi sokuvuleka sokuqina okuthuthukisiwe.
1. Umphumela wodaka olusanda kuhlanganiswa
1) Thuthukisa ukwakhiwa.
2) Ukugcinwa kwamanzi okwengeziwe ukuze kuthuthukiswe ukumuncwa kwesimende.
3) Khulisa ukusebenza kahle.
4) Gwema ukuqhekeka kusenesikhathi.
2. Umphumela wokuqinisa udaka
1) Nciphisa i-modulus enwebekayo yodaka bese wandisa ukuhambisana nesendlalelo sesisekelo.
2) Khulisa ukuguquguquka futhi umelane nokuqhekeka.
3) Thuthukisa ukumelana nokuwa kwempuphu.
4) Ukungathandi amanzi noma ukunciphisa ukumuncwa kwawo.
5) Khulisa ukunamathela kwesendlalelo sesisekelo.
Impuphu ye-latex ephinde ihlakazeke yakha i-polymer emulsion lapho ihlangana namanzi. Ngesikhathi senqubo yokuxuba nokomisa, i-emulsion iyaphela futhi. Impuphu ye-latex isebenza kumpuphu ye-putty, futhi inqubo yokwakheka kwesistimu ehlanganisiwe yokufakwa kwe-samente kanye nokwakheka kwefilimu yempuphu ye-latex iqedwa ngezinyathelo ezine:
①Uma i-latex powder ephinde ihlakazeke ixutshwe ngokulinganayo namanzi ku-putty powder, ihlakazeka ibe yizinhlayiya ezincane ze-polymer;
②Ijeli yesamente yakhiwa kancane kancane ngokumanziswa kokuqala kwesamente, isigaba soketshezi sigcwele i-Ca(OH)2 eyakhiwa ngesikhathi senqubo yokumanziswa, kanti izinhlayiya ze-polymer ezakhiwa yi-latex powder zifakwa ebusweni bejeli yesamente/ingxube yezinhlayiya zesamente ezingenamanzi;
③ Njengoba usimende uqhubeka umanziswa, amanzi asezimbotsheni zama-capillary ayancipha, futhi izinhlayiya ze-polymer zigcinwa kancane kancane ezimbotsheni zama-capillary, zakha ungqimba oluqinile ebusweni bejeli yesimende/ingxube yezinhlayiya zesimende ezingamanziswanga kanye nokugcwalisa;
④ Ngaphansi kwesenzo sokusabela kokumanzisa, ukumuncwa kwezingqimba zesisekelo kanye nokuhwamuka kobuso, umswakama uyancishiswa kakhulu, futhi izingqimba zokunqwabelana ezakhiwe zihlanganiswa zibe yifilimu encane, futhi imikhiqizo yokusabela kokumanzisa ihlanganiswa ndawonye ukuze kwakhiwe isakhiwo senethiwekhi esiphelele. Uhlelo oluhlanganisiwe olwakhiwe ngokumanzisa kwesimende kanye nokwakheka kwefilimu yempuphu ye-latex luthuthukisa ukumelana okunamandla kokuqhekeka kwe-putty.
Ngokombono wokusetshenziswa okungokoqobo, amandla e-putty asetshenziswa njengengqimba yokushintsha phakathi kokufakwa kwe-insulation yangaphandle kanye nokufakwa kodonga lwangaphandle akufanele abe phezulu kunokwe-plastering mortar, ngaphandle kwalokho kulula ukukhiqiza ukuqhekeka. Kuwo wonke uhlelo lokufakwa kwe-insulation, ukuguquguquka kwe-putty kufanele kube phezulu kunokwe-substrate. Ngale ndlela, i-putty ingazivumelanisa kangcono nokuguqulwa kwe-substrate futhi ivikele ukuguquguquka kwayo ngaphansi kwesenzo sezici zangaphandle zemvelo, inciphise ukugxila kokucindezeleka, futhi inciphise amathuba okuqhekeka nokuqhekeka kwe-coating.
