Izinto eziphambili ezenza umphezulu we-putty ungangeni manzi ube tyheli Emva kophando lwezinto eziphathekayo, inani elikhulu leemvavanyo kunye nokuziqhelanisa nobunjineli, umbhali ukholelwa ukuba izinto eziphambili ezenza umphezulu we-putty ungangeni manzi zibe tyheli zezi zilandelayo:
Isizathu 1. I-calcium hydroxide (umgubo we-calcium wothuthu) ibuyela kwi-alkali ibangela ukuba tyheli I-calcium hydroxide, ifomula yemolekyuli i-Ca (OH) 2, ubunzima bemolekyuli obuhambelanayo 74, indawo yokunyibilika 5220, ixabiso le-pH ≥ 12, i-alkaline enamandla, umgubo omhlophe ocolekileyo, Inyibilika kancinci emanzini, inyibilika kwi-asidi, i-glycerin, iswekile, i-ammonium chloride, inyibilika kwi-asidi ukuze ikhuphe ubushushu obuninzi, uxinano oluhambelanayo yi-2.24, isisombululo sayo samanzi esicacileyo lulwelo olucacileyo lwe-alkaline olungenambala, olungenavumba, kancinci kancinci Ifunxwa, i-calcium oxide iba yi-calcium carbonate. I-calcium hydroxide inamandla aphakathi kwi-alkaline, i-alkaline yayo kunye nokubola kwayo kubuthathaka kune-sodium hydroxide, i-calcium hydroxide kunye nesisombululo sayo samanzi ziyabola kulusu lomntu, impahla, njl.njl., kodwa azinatyhefu, kwaye akufuneki zinxibelelane ngqo nolusu ixesha elide.
I-calcium hydroxide sisizalisi esisebenzayo kwi-putty engangeni manzi ukuze yenze ifilimu eqinileyo ene-calcium carbonate enzima kunye nomgubo webhulabha oqaqambileyo. Ngenxa ye-alkalinity yayo enamandla kunye nomxholo ophezulu we-alkali, inxalenye yamanzi kwi-putty iya kufunxwa sisiseko sodonga ngexesha lokwakhiwa. Isiseko esifanayo se-alkaline cement mortar, okanye isiseko sesanti-lime (ilayimu, isanti, inani elincinci lesamente) siyafunxwa, njengoko umaleko we-putty woma kancinci kwaye amanzi etshintshatshintsha, izinto ze-alkaline kwi-mortar esezantsi kunye ne-putty kwaye ezinye zazo azizinzanga emva kwe-hydrolysis Izinto ezikwi-putty (ezifana ne-ferrous iron, i-ferric iron, njl.njl.) ziya kuphuma ngee-pores ezincinci ze-putty, kwaye kuya kwenzeka i-chemical reaction emva kokudibana nomoya, okubangela ukuba umphezulu we-putty ujike ube tyheli.
Isizathu sesi-2. Iigesi zekhemikhali eziphilayo eziguquguqukayo. Ezifana ne-carbon monoxide (CO), i-sulfur dioxide (SO2), i-benzene, i-toluene, i-xylene, i-formaldehyde, i-pyrotechnics, njl. Kwezinye iimeko zobunjineli, kubekho iimeko apho umphezulu we-putty ujike waba mthubi ngenxa yokusetyenziswa kwepeyinti kunye nomlilo ukugcina ubushushu kwigumbi apho i-putty engangeni manzi isandula ukukrwelwa, okanye kwanokutshisa isiqhumiso egumbini, kunye nabantu abaninzi betshaya ngaxeshanye.
Isizathu sesi-3. Impembelelo yemozulu kunye neemeko zokusingqongileyo. Kwingingqi esemantla, ngexesha lokutshintshiselana kwexesha lonyaka, umphezulu we-putty udla ngokuba mthubi ukusuka ngoNovemba ukuya kuMeyi wonyaka olandelayo, kodwa le yinto engaqhelekanga.
Isizathu sesi-4. Imeko yokungenisa umoya nokomisa ayilunganga. Udonga lumanzi. Emva kokukrwela i-putty engangeni manzi, ukuba umaleko we-putty awomi ngokupheleleyo, ukuvala iingcango neefestile ixesha elide kuya kubangela ukuba umphezulu we-putty ube tyheli ngokulula.
Isizathu sesi-5. Iingxaki zeengcambu zengca. Isiseko sodonga oludala ngokuqhelekileyo ludonga olungwevu-ngwevu (ilime, isanti, isamente encinci, kwaye ezinye zixutywe ne-gypsum). Nkosi yam, kodwa kusekho iindawo ezininzi apho iindonga zifakwe ilime kunye neplasta. Uninzi lwezinto zodonga ziyi-alkaline. Emva kokuba i-putty ichukumise udonga, amanzi athile aya kufunxwa ludonga. Emva kwe-hydrolysis kunye ne-oxidation, ezinye izinto, ezifana ne-alkali kunye ne-iron, ziya kuphuma ngee-pores ezincinci zodonga. Kwenzeka i-chemical reaction, ebangela ukuba umphezulu we-putty ube tyheli.
Isizathu 6. Ezinye izinto. Ukongeza kwezi zinto zinokwenzeka zingasentla, kuya kubakho nezinye izinto, ekufuneka ziqwalaselwe ngakumbi.
Isisombululo sokuthintela i-putty engangeni manzi ukuba ibuyele emthubi:
Indlela yoku-1. Sebenzisa i-arhente yokuvala umva ukuze uvale umva.
Indlela yesi-2. Kwimihombiso yodonga oludala, i-putty eqhelekileyo ekumgangatho ophantsi engangeni manzi kwaye kulula ukuyicola sele ikhuhliwe ngaphambili. Ngaphambi kokusebenzisa i-putty enganyangekiyo manzi ekumgangatho ophezulu, unyango lobuchwephesha kufuneka lwenziwe kuqala. Le ndlela yile: qala ngokufafaza amanzi ukuze umanzise umphezulu wodonga, kwaye usebenzise i-spatula ukuyisula. Susa yonke i-putty endala uze uyipeyinte (de ibe sezantsi) kwaye uyicoce. Emva kokuba udonga lomile ngokupheleleyo, lucoce kwakhona kwaye ufake i-backing agent ukugubungela unyango lwe-backing, uze ukrwele i-putty enganyangekiyo manzi. tyheli.
Indlela yesi-3. Ziphephe iigesi zeekhemikhali eziguquguqukayo kunye neefireworks. Ngexesha lokwakha, ingakumbi xa i-putty ingomi ngokupheleleyo emva kokwakha, musa ukutshaya okanye ukubasa umlilo ngaphakathi ukuze ufudumale, kwaye musa ukusebenzisa iikhemikhali eziguquguqukayo ezifana nepeyinti kunye nezinto ezinciphayo ngaphakathi ngaphakathi kwiinyanga ezintathu.
Indlela yesi-4. Gcina indawo ingena umoya kwaye yomile. Ngaphambi kokuba i-putty engangeni manzi yome ngokupheleleyo, musa ukuvala iingcango kunye neefestile ngokuqinileyo, kodwa vula iifestile ukuze umoya ungene, ukuze umaleko we-putty wome ngokukhawuleza.
Indlela yesi-5. Isixa esifanelekileyo se-462 modified ultramarine singongezwa kwi-putty engangeni manzi. Indlela ethile: Ngokwesilinganiso se-462 modified ultramarine: i-putty powder = 0.1: 1000, qala ngokongeza i-ultramarine kwisixa esithile samanzi, uvuselele ukuze unyibilike kwaye uhluze, yongeza isisombululo samanzi se-ultramarine kunye namanzi kwisitya, uze ucinezele amanzi apheleleyo: i-putty powder = 0.5 : 1 weight ratio, faka i-putty powder kwisitya, uvuselele ngokulinganayo ngomxube ukuze wenze ubisi olukhrimu, uze ulusebenzise. Uvavanyo lubonisa ukuba ukongeza isixa esithile se-ultramarine blue kunokuthintela umphezulu we-putty ekubeni ujike ube tyheli ukuya kwinqanaba elithile.
Indlela 6. Kwi-putty ejike yaba tyheli, kufuneka unyango lobuchwephesha. Indlela yonyango ngokubanzi yile: kuqala faka i-primer kumphezulu we-putty, uze emva koko ukrwele uze ufake i-putty esemgangathweni ophezulu okanye ipeyinti ye-latex yodonga engaphakathi enebrashi.
Shwankathela la manqaku angasentla:
Ukutyheli komphezulu wepeyinti engangeni manzi kunye nepeyinti yeporcelain yokulinganisa kubandakanya izinto ezininzi ezifana nezinto ezikrwada, iimeko zokusingqongileyo, iimeko zemozulu, isiseko sodonga, iteknoloji yokwakha, njl. Yingxaki enzima kakhulu, kwaye kufuneka uphando olongezelelweyo kunye nengxoxo.
