1. I-Putty isetshenziswa njengempahla yokulungiswa kwangaphambili kwendawo ukuze ihlanganiswe ngezingubo zezakhiwo
I-Putty iyingqimba encane yodaka olulinganisayo. I-Putty iklwetshiwe phezu kwama-substrates amaholoholo (njengokhonkolo, udaka olusezingeni, i-gypsum board, njll.) Yenza ungqimba lukapende lwangaphandle lube bushelelezi futhi luntekenteke, kungabi lula ukunqwabelana uthuli futhi kube lula ukuluhlanza (lokhu kubaluleke kakhulu ezindaweni ukungcoliswa komoya okubi kakhulu). I-putty ingahlukaniswa ibe yi-putty yengxenye eyodwa (unamathisele i-putty unamathisele kanye ne-powder putty eyomile) kanye ne-putty yezingxenye ezimbili (ehlanganiswe ne-putty powder kanye ne-emulsion) ngokusho kwefomu lomkhiqizo ophelile. Ngokunaka kwabantu kubuchwepheshe bokwakhiwa kwezingubo zezakhiwo, i-putty njengento ebalulekile yokusekela nayo iye yathuthukiswa ngokufanele. Abakhiqizi abahlukahlukene basekhaya baye bahlakulela i-putty ngezinhloso ezahlukene kanye nezinhlobo ezahlukene, njenge-powder putty, i-paste putty, i-putty yodonga lwangaphakathi, i-putty yangaphandle, i-elastic putty, njll.
Uma sibheka ekusetshenzisweni kwangempela kwezingubo zezakhiwo zasekhaya, kuvame ukuba nezinkinga ezifana nokukhipha amagwebu nokuxebuka, okuthinta kakhulu ukuvikelwa nokusebenza komhlobiso wezingubo ezakhiweni. Kunezizathu ezimbili eziyinhloko zokulimala kwefilimu yokugqoka:
Enye izinga likapende;
Okwesibili ukuphatha okungalungile kwe-substrate.
Ukuzijwayeza kubonise ukuthi ngaphezu kuka-70% ukwehluleka kokumboza kuhlobene nokungaphathwa kahle kwe-substrate. I-Putty yezingubo zokuklama isetshenziswe kabanzi njengempahla eluhlaza ukuze kufakwe ngaphambili ukulungiswa kwendawo. Ayikwazi ukushelela kuphela futhi ilungise ubuso bezakhiwo, kodwa futhi i-putty yekhwalithi ephezulu ingathuthukisa kakhulu ukuvikelwa nokusebenza komhlobiso wezingubo ezakhiweni. Ukwelula impilo yesevisi yokumboza kuwumkhiqizo osekelayo obalulekile wezingubo zezakhiwo ezisebenza kahle kakhulu, ikakhulukazi izimbozo zangaphandle. I-putty ye-powder eyomile enengxenye eyodwa inezinzuzo ezisobala zezomnotho, ezobuchwepheshe nezemvelo ekukhiqizeni, ezokuthutha, ukugcina, ukwakhiwa nokunye.
Qaphela: Ngenxa yezinto ezifana nezinto zokusetshenziswa kanye nezindleko, impushana ye-polymer ehlakazekayo isetshenziswa kakhulu kumpushana we-anti-cracking wezindonga zangaphandle, futhi ibuye isetshenziswe ku-putty yokupholisha odongeni yezinga eliphezulu.
2. Indima ye-anti-cracking putty yezindonga zangaphandle
I-wall putty yangaphandle ngokuvamile isebenzisa usimende njengento ehlanganisayo engaphili, futhi inani elincane le-calcium yomlotha lingangezwa ukuze kuzuzwe umphumela we-synergistic. Indima ye-anti-cracking putty esekwe kusimende ezindongeni zangaphandle:
I-surface layer putty ihlinzeka ngesisekelo esihle, esinciphisa inani lopende futhi sinciphise izindleko zephrojekthi;
I-Putty inokunamathela okuqinile futhi ingaxhunywa kahle odongeni lwesisekelo;
Inokuqina okuthile, ingavimba kahle umthelela wokunwebeka okuhlukene kanye nezingcindezi zokufinyeza zezigaba ezihlukene zesisekelo, futhi inokumelana nokuqhekeka okuhle;
I-Putty inokumelana nesimo sezulu esihle, ukungakwazi ukungena emanzini, ukumelana nomswakama kanye nesikhathi eside sesevisi;
Inobungani nemvelo, ayinabo ubuthi futhi iphephile;
Ngemuva kokuguqulwa kwezithasiselo ezisebenzayo, njenge-putty rubber powder nezinye izinto, i-putty yangaphandle yodonga nayo ingaba nezinzuzo ezengeziwe zokusebenza ezilandelayo:
Umsebenzi wokukhuhla okuqondile ekuqedeni okudala (upende, uthayela, i-mosaic, itshe nezinye izindonga ezibushelelezi);
I-thixotropy enhle, indawo ecishe iphelele ebushelelezi ingatholwa ngokumane ugcobe, futhi ukulahlekelwa okubangelwa ukumbozwa kokusetshenziswa okuningi ngenxa yesisekelo esingalingani sobuso kuyancishiswa;
Iyanwebeka, ingakwazi ukumelana nemifantu emincane, futhi ingasusa umonakalo wokucindezeleka kwezinga lokushisa;
Ukuxosha amanzi okuhle nokusebenza okungangeni manzi.
3. Indima yempushana ye-latex ehlakazeka kabusha kumpushana we-putty odongeni
(1) Umthelela wempuphu yerabha eyi-putty ku-putty esanda kuxutshwa:
Thuthukisa ukusebenza kahle futhi uthuthukise ukusebenza kwe-putty batch scraping;
ukugcinwa kwamanzi okwengeziwe;
ukwanda kokusebenza;
Gwema ukuqhekeka kusenesikhathi.
(2) Umthelela wempuphu yerabha eyi-putty ku-putty eqinile:
Yehlisa i-elastic modulus ye-putty futhi uthuthukise ukufanisa kungqimba oluyisisekelo;
Thuthukisa isakhiwo se-micro-pore sikasimende, ukwandisa ukuguquguquka ngemva kokwengeza i-putty rubber powder, futhi umelane nokuqhekeka;
Thuthukisa ukumelana ne-powder;
I-Hydrophobic noma ukunciphisa ukumuncwa kwamanzi kwesendlalelo se-putty;
Khulisa ukunamathela kwe-putty odongeni lwesisekelo.
Okwesine, izidingo zenqubo yokwakhiwa kwe-putty yangaphandle
Inqubo yokwakha i-putty kufanele inake:
1. Umthelela wezimo zokwakha:
Umthelela wezimo zokwakha ngokuyinhloko izinga lokushisa kanye nomswakama wendawo ezungezile. Ezimweni ezishisayo, ungqimba oluyisisekelo kufanele lufafazwe kahle ngamanzi, noma lugcinwe lumanzi, kuye ngokusebenza komkhiqizo othize we-putty powder. Njengoba i-putty powder yangaphandle isebenzisa kakhulu usimende njengento engusimende, izinga lokushisa le-ambient liyadingeka ukuthi lingabi ngaphansi kwama-degree angu-5, futhi ngeke liqandiswe ngaphambi kokuqina ngemva kokwakhiwa.
2. Ukulungiselela kanye nezinyathelo zokuphepha ngaphambi kokukhuhla i-putty:
Kudingeka ukuthi umsebenzi oyinhloko usuqediwe, futhi isakhiwo nophahla sekuqediwe;
Zonke izingxenye ezishumekiwe, iminyango, amafasitela namapayipi esisekelo somlotha kufanele kufakwe;
Ukuvimbela ukungcoliswa kanye nokulimala emikhiqizweni eqediwe enqubweni ye-batch scraping, izinto ezithile zokuvikela kanye nezinyathelo kufanele zinqunywe ngaphambi kokukhuhla kwenqwaba, futhi izingxenye ezifanele kufanele zimbozwe futhi zigoqwe;
Ukufakwa kwefasitela kufanele kwenziwe ngemuva kokuba i-putty batch ikhishwe.
3. Ukwelashwa kwendawo:
Ubuso be-substrate kufanele buqine, bube bushelelezi, bomile futhi buhlanzeke, bungabi namafutha, i-batik nezinye izinto ezixekethile;
Ingaphezulu le-plastering entsha kufanele zelashwe izinsuku ezingu-12 ngaphambi kokuba i-putty ikhishwe, futhi ungqimba lokuqala lokukhonkolo alukwazi ukufakwa ngekhalenda nge-cement paste;
Uma udonga lome kakhulu ngaphambi kokwakhiwa, udonga kufanele lumanziswe kusengaphambili.
4. Inqubo yokusebenza:
Thela inani elifanele lamanzi esitsheni, bese ufaka i-putty powder eyomile, bese ugoqa ngokugcwele nge-mixer kuze kube unamathisele ofanayo ngaphandle kwezinhlayiya ze-powder kanye nemvula;
Sebenzisa ithuluzi lokukhuhla iqoqo lokukhuhla inqwaba, futhi ukuklwebha kwenqwaba kungenziwa ngemuva kokuthi ungqimba lokuqala lokushumeka kwenqwaba sekuqediwe cishe amahora ama-4;
Khwebula ungqimba lwe-putty ngokushelela, futhi ulawule ukujiya kube ngu-1.5mm;
I-putty esekwe kusimende ingapendwa nge-primer engamelana ne-alkali kuphela ngemva kokuba ukuphulukiswa kwemvelo sekuqediwe kuze kube yilapho i-alkalinity namandla kuhlangabezana nezidingo;
5. Amanothi:
Ukuma nokucaba kwe-substrate kufanele kunqunywe ngaphambi kokwakhiwa;
Udaka lwe-putty oluxubile kufanele lusetshenziswe ngaphakathi kwe-1 ~ 2h (kuye ngokuthi ifomula);
Ungahlanganisi i-putty mortar eyeqe isikhathi sokusebenzisa namanzi ngaphambi kokuyisebenzisa;
Kufanele iphuculwe ngaphakathi kwe-1 ~ 2d;
Lapho isisekelo sesisekelo se-calendered ngodaka lukasimende, kunconywa ukusebenzisa i-ejenti yokwelapha esibonakalayo noma i-interface putty kanye ne-elastic putty.
Umthamo wei-polymer powder ehlakazeka kabushaingabhekisela kudatha yomthamo kufomula ye-putty yodonga lwangaphandle. Kunconywa ukuthi amakhasimende enze izivivinyo ezimbalwa zesampula ezincane ngaphambi kokukhiqiza ngobuningi ukuze kuqinisekiswe ikhwalithi ye-putty powder.
