Izici eziyinhloko zokuphuzi kobuso be-putty engavimbeli amanzi Ngemva kocwaningo lwezinto ezibonakalayo, inani elikhulu lokuhlolwa kanye nomkhuba wobunjiniyela, umbhali ukholelwa ukuthi izici eziyinhloko zokuphuzi kobuso be-putty ukumelana namanzi zimi kanje: :
Isizathu 1. I-calcium hydroxide (impushana yomlotha we-calcium) ibuyela ku-alkali ibangela ukuphuzi kwe-Calcium hydroxide, ifomula yamangqamuzana i-Ca (OH) 2, isisindo samangqamuzana esihlobene 74, indawo yokuncibilika engu-5220, inani le-pH ≥ 12, i-alkaline eqinile, impushana emhlophe, I-Soluble kancane amanzi, ancibilika ku-asidi, glycerin, ushukela, ammonium chloride, ancibilika ku-asidi ukuze akhulule ukushisa, ukuminyana kwesihlobo kungu-2.24, isixazululo saso esicacile samanzi siwuketshezi olungenambala, olungenaphunga olune-alkali esobala, kancane kancane luyamunywa, i-calcium oxide iba yi-calcium carbonate. I-calcium hydroxide ine-alkaline eqinile ngokusesilinganisweni, i-alkalinity yayo kanye nokugqwala kwayo ibuthakathaka kune-sodium hydroxide, i-calcium hydroxide futhi isixazululo sayo esinamanzi siyagqwala esikhumbeni somuntu, ezingutsheni, njll., kodwa ayinabo ubuthi, futhi akufanele ihlangane ngqo nesikhumba isikhathi eside.
I-Calcium hydroxide iyisigcwalisi esisebenzayo ku-putty engangeni emanzini ukuze yakhe ifilimu eqinile ene-calcium carbonate esindayo kanye nempushana yerabha ecwebezelayo. Ngenxa ye-alkalinity eqinile kanye nokuqukethwe okuphezulu kwe-alkali, ingxenye yamanzi ku-putty izomuncwa isisekelo sodonga ngesikhathi sokwakhiwa. Okufanayo okufanayo okuqinile kukasimende okungaphansi, noma phansi kwe-sand-lime (i-lime, isihlabathi, isamba esincane sikasimende) kuyamuncwa, njengoba ungqimba lwe-putty loma kancane kancane futhi amanzi ayashintshashintsha, izinto ze-alkaline osikeni oluphansi kanye ne-putty kanye nokunye azinzile ngemva kwe-hydrolysis Izinto ezise-putty (njenge-iron ferrous, i-ferric iron, njll.) zizophuma izimbotshana ze-putty, futhi ukusabela kwamakhemikhali kuzokwenzeka ngemva kokuhlangana nomoya, okwenza ubuso be-putty buphenduke buphuzi.
Isizathu 2. Amagesi amakhemikhali aphilayo aguquguqukayo. Okufana ne-carbon monoxide (CO), i-sulphur dioxide (SO2), i-benzene, i-toluene, i-xylene, i-formaldehyde, i-pyrotechnics, njll. Kwezinye izimo zobunjiniyela, kube nezimo lapho i-putty surface ibe phuzi ngenxa yokusetshenziswa kopende kanye umlilo ukuze ufudumale ekamelweni lapho i-putty engavimbeli amanzi isanda kuchithwa, noma ishisa impepho ekamelweni, futhi abantu abaningi bayabhema ngesikhathi esifanayo.
Isizathu 3. Umthelela wesimo sezulu kanye nezici zemvelo. Esifundeni esisenyakatho, ngesikhathi sokushintshana kwesizini, ingaphezulu le-putty livame ukuphenduka libe phuzi kusukela ngoNovemba kuya kuMeyi wonyaka olandelayo, kodwa lokhu kumane kuyisimo esizimele.
Isizathu 4. Isimo sokungena komoya kanye nokomisa asisihle. Udonga lumanzi. Ngemuva kokukhipha i-putty engavimbeli amanzi, uma ungqimba lwe-putty lungasomile ngokuphelele, ukuvala iminyango namafasitela isikhathi eside kuzokwenza kalula ukuthi ubuso be-putty buphenduke buphuzi.
Isizathu 5. Izinkinga zeGrassroots. Phansi kodonga oludala ngokuvamile kuwudonga olumpunga ngesihlabathi (umcako, isihlabathi, isamba esincane sikasimende, futhi okunye okuxutshwe ne-gypsum). Nkosi, kodwa ziseziningi izindawo lapho izindonga zifakwe umcako nokhonkolo. Iningi lezinto zodonga zine-alkaline. Ngemuva kokuthi i-putty ithinte udonga, amanzi athile azothathwa udonga. Ngemva kwe-hydrolysis ne-oxidation, ezinye izinto, njenge-alkali nensimbi, zizophuma ngezimbotshana ezincane zodonga. Ukusabela kwamakhemikhali kwenzeka, okwenza ubuso be-putty buphenduke buphuzi.
Isizathu 6. Ezinye izici. Ngaphezu kwalezi zici ezingenhla, kuzoba nezinye izici, okudingeka zibhekwe kabanzi.
Isixazululo sokuvimbela i-putty engavimbeli amanzi ukuthi ibuyele kokuphuzi:
Indlela 1. Sebenzisa i-back-sealing ejenti yokuvala emuva.
Indlela yesi-2. Ngokuhlobisa odongeni oludala, i-putty yezinga eliphansi elivamile elingakwazi ukumelana namanzi futhi kulula ukulihlikihla liye lakhunyulwa ngaphambili. Ngaphambi kokusebenzisa i-putty engavimbeli amanzi esezingeni eliphezulu, ukwelashwa kobuchwepheshe kufanele kwenziwe kuqala. Indlela iwukuthi: qala ngokufafaza amanzi ukuze umanzise ubuso bodonga, bese usebenzisa i-spatula ukuze uyisule Susa yonke i-putty endala nopende (kuze kube phansi kanzima) futhi uyihlanze. Ngemuva kokuthi udonga lomile ngokuphelele, luhlanze futhi futhi usebenzise i-ejenti esekelayo ukumboza ukwelashwa okusekelayo, bese usula i-putty engavimbeli amanzi. ophuzi.
Indlela yesi-3. Gwema amagesi amakhemikhali aguquguqukayo neziqhumane. Phakathi nenqubo yokwakha, ikakhulukazi lapho i-putty ingasomile ngokuphelele ngemva kokwakhiwa, ungabhemi noma ubasa umlilo endlini ukuze ufudumale, futhi ungasebenzisi amakhemikhali aguquguqukayo afana nopende kanye nama-thiners awo endlini phakathi nezinyanga ezintathu.
Indlela 4. Gcina indawo ingena umoya futhi yomile. Ngaphambi kokuba i-putty engavimbeli amanzi isomile ngokuphelele, ungavali iminyango namafasitela ngokuqinile, kodwa vula amafasitela ukuze kungene umoya, ukuze ungqimba lwe-putty lome ngokushesha ngangokunokwenzeka.
Indlela 5. Inani elifanele le-ultramarine elungisiwe engu-462 lingangezwa ku-putty engangeni manzi. Indlela eqondile: Ngokwesilinganiso se-ultramarine eguquliwe engu-462: i-putty powder = 0.1: 1000, qala ngokufaka i-ultramarine enanini elithile lamanzi, ugovuze ukuze incibilike futhi ucwenge, engeza isixazululo samanzi se-ultramarine namanzi esitsheni, bese ucindezela Amanzi aphelele: i-putty powder = 0.5: 1 isilinganiso sesisindo, faka i-putty powder esitsheni, uyixube ngokulinganayo nge-mixer ukuze wenze ubisi olunokhilimu, bese ulusebenzisa. Ukuhlola kubonisa ukuthi ukwengeza inani elithile le-ultramarine eluhlaza okwesibhakabhaka kungavimbela ingaphezulu le-putty ekubeni liphuzi lifinyelele ezingeni elithile.
Indlela yesi-6. Nge-putty ephenduke yaba phuzi, ukwelashwa kobuchwepheshe kuyadingeka. Indlela yokwelapha evamile yilena: faka kuqala i-primer phezu kwe-putty, bese ukhuhla futhi usebenzise i-putty engavimbeli amanzi yezinga eliphezulu noma ibhulashi langaphakathi lopende we-latex odongeni.
Fingqa amaphuzu angenhla:
Umbala ophuzi ongaphezulu we-putty ukumelana namanzi kanye nopende we-porcelain wokulingisa kuhilela izici eziningi ezifana nempahla eluhlaza, izimo zemvelo, izimo zezulu, isisekelo sodonga, ubuchwepheshe bokwakha, njll. Kuyinkinga eyinkimbinkimbi, futhi ucwaningo olwengeziwe nengxoxo kuyadingeka.
