Emaphrojekthini okwakha, i-putty powder eguquguqukayo yodonga lwangaphandle, njengenye yezinto ezibalulekile zokuhlobisa, isetshenziswa kabanzi ukuthuthukisa ukuba yisicaba kanye nomphumela wokuhlobisa wodonga lwangaphandle. Ngokuthuthuka kokulondolozwa kwamandla okwakha kanye nezidingo zokuvikela imvelo, ukusebenza kwe-putty powder yodonga lwangaphandle nakho kuye kwathuthukiswa njalo futhi kwathuthukiswa.I-Powder ye-Polymer ephinde ihlakazeke (RDP) Njengesengezo esisebenzayo, sidlala indima ebalulekile ku-powder ye-putty eguquguqukayo odongeni lwangaphandle.
1. Umqondo oyisisekelo weI-Powder ye-Polymer ephinde ihlakazeke (RDP)
I-Powder ye-Polymer ephinde ihlakazeke (RDP) iyimpuphu eyenziwe ngokomisa i-latex esuselwe emanzini ngenqubo ekhethekile, engaphinde ihlakazwe emanzini ukuze yakhe i-emulsion ezinzile. Izingxenye zayo eziyinhloko zivame ukufaka ama-polymer afana ne-polyvinyl alcohol, i-polyacrylate, i-polyvinyl chloride, kanye ne-polyurethane. Ngenxa yokuthi ingaphinde ihlakazwe emanzini futhi yakhe ukunamathela okuhle nezinto eziyisisekelo, isetshenziswa kabanzi ezintweni zokwakha ezifana nokugqoka kwezakhiwo, udaka olomile, kanye ne-wall putty yangaphandle.
2. Indima kaI-Powder ye-Polymer ephinde ihlakazeke (RDP) ku-putty powder eguquguqukayo yezindonga zangaphandle
Thuthukisa ukuguquguquka kanye nokumelana nokuqhekeka kwempuphu ye-putty
Omunye wemisebenzi eyinhloko yempuphu ye-putty eguquguqukayo yezindonga zangaphandle ukulungisa nokwelapha imifantu ebusweni bezindonga zangaphandle.I-Powder ye-Polymer ephinde ihlakazeke (RDP) Ukufaka i-putty powder kungathuthukisa kakhulu ukuguquguquka kwe-putty powder futhi kwenze ukuthi imelane nokuqhekeka. Ngesikhathi sokwakhiwa kwezindonga zangaphandle, umehluko wokushisa wendawo yangaphandle uzokwenza ukuthi udonga lukhule futhi lunciphe. Uma i-putty powder ngokwayo ingenakho ukuguquguquka okwanele, imifantu izovela kalula.I-Powder ye-Polymer ephinde ihlakazeke (RDP) ingathuthukisa ngempumelelo ukuqina kanye namandla okuthamba kwesendlalelo se-putty, ngaleyo ndlela inciphise ukuvela kwemifantu futhi igcine ubuhle nokuqina kodonga lwangaphandle.
Thuthukisa ukunamathela kwempuphu ye-putty
Ukunamathela kwempuphu ye-putty ezindongeni zangaphandle kuhlobene ngqo nomphumela wokwakha kanye nokuphila kwenkonzo.I-Powder ye-Polymer ephinde ihlakazeke (RDP) kungathuthukisa ukunamathelana phakathi kwempuphu ye-putty kanye ne-substrate (njengekhonkrithi, ukwakhiwa kwetshe, njll.) futhi kuthuthukise ukunamathelana kwengqimba ye-putty. Ekwakhiweni kwezindonga zangaphandle, ubuso be-substrate buvame ukukhululeka noma bubushelelezi, okwenza kube nzima ngempuphu ye-putty ukunamathela ngokuqinile. Ngemva kokwengezaI-Powder ye-Polymer ephinde ihlakazeke (RDP), izinhlayiya ze-polymer ku-latex powder zingakha isibopho esiqinile esibonakalayo nobuso be-substrate ukuvimbela ungqimba lwe-putty ukuthi lungawi noma luqhekeke.
Thuthukisa ukumelana namanzi kanye nokumelana nesimo sezulu kwempuphu ye-putty
Impuphu ye-wall putty yangaphandle ivezwa endaweni engaphandle isikhathi eside futhi ibhekene novivinyo lwesimo sezulu esibi njengomoya, ilanga, imvula kanye nokuguguleka.I-Powder ye-Polymer ephinde ihlakazeke (RDP) kungathuthukisa kakhulu ukumelana namanzi kanye nokumelana nesimo sezulu kwempuphu ye-putty, okwenza ungqimba lwe-putty lungathinteki kalula ekugugulekeni komswakama, ngaleyo ndlela kwandise impilo yesevisi yodonga lwangaphandle. I-polymer empuphu ye-latex ingakha ifilimu evikelayo eqinile ngaphakathi kwengqimba ye-putty, ihlukanise ngempumelelo ukungena komswakama futhi ivimbele ungqimba lwe-putty ukuthi lungawi, lushintshe umbala noma luguge.
Thuthukisa ukusebenza kokwakha
I-Powder ye-Polymer ephinde ihlakazeke (RDP) Ayikwazi nje ukuthuthukisa ukusebenza kokugcina kwempuphu ye-putty, kodwa futhi ithuthukisa ukusebenza kwayo kokwakhiwa. Impuphu ye-putty ngemuva kokufaka i-latex powder inokuguquguquka okungcono nokusebenza kokwakhiwa, okungathuthukisa ukusebenza kahle kokwakhiwa futhi kunciphise ubunzima bokusebenza kwabasebenzi. Ngaphezu kwalokho, isikhathi sokomisa sempuphu ye-putty sizolungiswa, okungagwema imifantu ebangelwa ukoma okusheshayo kakhulu kwengqimba ye-putty, futhi kungagwema ukoma okuhamba kancane okuthinta inqubekela phambili yokwakha.
3. Indlela yokusebenzisaI-Powder ye-Polymer ephinde ihlakazeke (RDP) ekwakhiweni kwefomula ye-putty powder eguquguqukayo yezindonga zangaphandle
Khetha ngokufanele uhlobo kanye nenani lokwengeza le-latex powder
OkuhlukileI-Powder ye-Polymer ephinde ihlakazeke (RDP)Inezici zokusebenza ezahlukene, okuhlanganisa ukumelana nokuqhekeka, ukunamathela, ukumelana namanzi, njll. Lapho uklama ifomula, uhlobo olufanele lwempuphu ye-latex kufanele lukhethwe ngokuya ngezidingo zangempela zokusetshenziswa kwempuphu ye-putty kanye nendawo yokwakha. Isibonelo, impuphu ye-putty yangaphandle yodonga esetshenziswa ezindaweni ezinomswakama kufanele ikhethe impuphu ye-latex enokumelana namanzi okunamandla, kuyilapho impuphu ye-putty esetshenziswa ezindaweni ezinokushisa okuphezulu nezomile ingakhetha impuphu ye-latex enokuguquguquka okuhle. Inani lokwengeza lempuphu ye-latex ngokuvamile liphakathi kuka-2% no-10%. Kuye ngefomula, inani elifanele lokwengeza lingaqinisekisa ukusebenza ngenkathi kugwenywa ukwengeza ngokweqile okuholela ekwandeni kwezindleko.
Ukusebenzisana nezinye izithasiselo
I-Powder ye-Polymer ephinde ihlakazeke (RDP) ivame ukusetshenziswa nezinye izithasiselo ezifana nezithisi, ama-antifreeze agents, ama-water reducers, njll., ukwakha umphumela wokubambisana ekwakhiweni kwefomula ye-putty powder. Ama-thickeners angathuthukisa i-viscosity ye-putty powder futhi athuthukise ukusebenza kwayo ngesikhathi sokwakha; ama-antifreeze agents angathuthukisa ukusebenza kokwakhiwa kwe-putty powder ezindaweni eziphansi zokushisa; ama-water reducers angathuthukisa izinga lokusetshenziswa kwamanzi kwe-putty powder futhi anciphise izinga lokuhwamuka kwamanzi ngesikhathi sokwakha. Izilinganiso ezifanele zingenza i-putty powder ibe nokusebenza okuhle kakhulu nemiphumela yokwakha.
I-RDP inenani elibalulekile lokusetshenziswa ekwakhiweni kwefomula yempuphu ye-putty eguquguqukayo yezindonga zangaphandle. Ayikwazi nje ukuthuthukisa ukuguquguquka, ukumelana nokuqhekeka, ukunamathela kanye nokumelana nesimo sezulu kwempuphu ye-putty, kodwa futhi ithuthukise ukusebenza kokwakhiwa futhi yandise impilo yesevisi yesendlalelo sokuhlobisa udonga lwangaphandle. Lapho uklama ifomula, ukukhetha ngokufanele inani elihlukahlukene kanye nenani lokwengeza lempuphu ye-latex nokuyisebenzisa kanye nezinye izithasiselo kungathuthukisa kakhulu ukusebenza kwempuphu ye-putty eguquguqukayo yezindonga zangaphandle futhi kuhlangabezane nezidingo zezakhiwo zesimanje zokuhlobisa nokuvikela udonga lwangaphandle. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, ukusetshenziswa kweI-Powder ye-Polymer ephinde ihlakazeke (RDP) izodlala indima ebaluleke kakhulu ezintweni zokwakha esikhathini esizayo.
