Izinto eziphambili ze-yellowing ebusweni be-putty enganyangekiyo emanzini Emva kophando lwezinto eziphathekayo, inani elikhulu leemvavanyo kunye nokusebenza kobunjineli, umbhali ukholelwa ukuba ezona zinto ziphambili zokutyheli komphezulu weputty enganyangekiyo ngamanzi zimi ngolu hlobo lulandelayo. :
Isizathu 1. I-calcium hydroxide (i-ash calcium powder) ibuyela kwi-alkali ibangela i-alkali ye-yellowing, i-formula ye-molecular Ca (OH) 2, ubunzima be-molecular 74, i-melting point 5220, ixabiso le-pH ≥ 12, i-alkaline eyomeleleyo, umgubo ococekileyo omhlophe, i-Soluble kancinane amanzi, anyibilika kwiasidi, iglycerin, iswekile, iammonium chloride, inyibilika kwiasidi ukukhulula okuninzi. ubushushu, ingxinano yesalamane yi-2.24, isisombululo sayo esicacileyo samanzi silulwelo olungenambala, olungenavumba lwealkaline olucacileyo, ngokuthe ngcembe lufunxwa, i-calcium oxide iba yi-calcium carbonate. Icalcium hydroxide yomelele ngokuphakathi, ialkalinity yayo kunye nokubola kwayo buthathaka kunesodium hydroxide, calcium hydroxide kwaye isisombululo sayo samanzi siyingozi eluswini lomntu, impahla, njl. njl., kodwa ayinayo ityhefu, kwaye akufuneki idibane ngqo nolusu ixesha elide.
I-calcium hydroxide yi-filler esebenzayo kwi-putty enganyangekiyo emanzini ukwenza ifilimu enzima kunye ne-calcium carbonate enzima kunye ne-high-gloss rubber powder. Ngenxa ye-alkalinity eyomeleleyo kunye nomxholo ophezulu we-alkali, inxalenye yamanzi kwi-putty iya kuthatyathwa yisiseko sodonga ngexesha lokwakhiwa. Okufanayo okunamandla ealkaline yesamente yodaka ezantsi, okanye kwisanti-lime ezantsi (ikalika, isanti, isixa esincinci sesamente) iyafunxwa, njengoko umaleko we-putty woma ngokuthe ngcembe kwaye amanzi aguquke, izinto zealkali kudaka olusezantsi kunye neputty kunye nezinye aziqinisekanga emva kwe-hydrolysis Izinto kwi-putty (ezifana ne-iron, i-iron, i-iron, njl.njl.) ziya kuphuma ngencinci. i-pores ye-putty, kunye ne-chemical reaction iya kwenzeka emva kokudibana nomoya, okubangela ukuba umphezulu we-putty ujike ube tyheli.
Isizathu 2. Iigesi eziguquguqukayo zeekhemikhali eziphilayo. Okufana necarbon monoxide (CO), sulfur dioxide (SO2), benzene, toluene, xylene, formaldehyde, pyrotechnics, njalo njalo. Kwezinye iimeko zobunjineli, kuye kwakho iimeko apho umphezulu weputty ujike watyheli ngenxa yokusetyenziswa kwepeyinti kunye ne umlilo ukuze uhlale ufudumele kwigumbi apho i-putty enganyangekiyo yamanzi isanda kukhutshelwa, okanye ukutshisa isiqhumiso kwigumbi, kwaye abantu abaninzi bayatshaya ngaxeshanye.
Isizathu 3. Impembelelo yemozulu kunye nemiba yokusingqongileyo. Kwingingqi esemantla, ngexesha lokutshintshiselana kwexesha lonyaka, umphezulu weputty udla ngokujika umthubi ukusuka ngoNovemba ukuya kuMeyi wonyaka olandelayo, kodwa le yinto nje eyodwa.
Isizathu 4. Imeko yokungena komoya kunye nokomisa ayilungile. Udonga lumanzi. Emva kokukrazula i-putty enganyangekiyo yamanzi, ukuba i-putty layer ayomile ngokupheleleyo, ukuvala iingcango kunye neefestile ixesha elide kuya kubangela ukuba ubuso be-putty bujike bube tyheli.
Isizathu 5. Imiba yeGrassroots. Umzantsi wodonga oludala ngokuqhelekileyo ludonga lwesanti-grey (ikalika, isanti, isixa esincinci sesamente, kunye nezinye ezixutywe negypsum). Nkosi, kodwa kusekho iindawo ezininzi apho iindonga zityatyekwe ngekalika kunye nodaka. Uninzi lwezixhobo zodonga zi-alkaline. Emva kokuba i-putty ichukumisa udonga, amanzi athile aya kuxutywa eludongeni. Emva kwe-hydrolysis kunye ne-oxidation, ezinye izinto, ezifana ne-alkali kunye nentsimbi, ziya kuphuma ngeembobo ezincinci eludongeni. Ukusabela kweekhemikhali kwenzeka, okubangela ukuba umphezulu weputty ujike ube tyheli.
Isizathu 6. Ezinye izinto. Ukongeza kule miba ingasentla enokwenzeka, kuya kubakho ezinye izinto, ezifuna ukuphononongwa ngakumbi.
Isisombululo sokuthintela iputty enganyangekiyo ngamanzi ukuba ibuyele kumthubi:
Indlela yoku-1. Sebenzisa i-agent yokutywina ngasemva ukutywinwa ngasemva.
Indlela yesi-2. Ukuhlobisa udonga oludala, i-putty ye-low-grade yesiqhelo engenamanzi kwaye kulula ukuyicoca iye yachithwa ngaphambili. Ngaphambi kokusebenzisa i-putty ye-high-grade-resistant water-resistant, unyango lwezobugcisa kufuneka lwenziwe kuqala. Indlela yile: kuqala ukutshiza amanzi ukumanzisa umphezulu wodonga, kwaye usebenzise i-spatula ukuyisula Susa yonke i-putty endala kunye nepeyinti (de kube nzima ezantsi) kwaye uyicoce. Emva kokuba udonga lome ngokupheleleyo, luhlambulule kwakhona kwaye usebenzise i-agent exhasayo ukugubungela unyango oluxhasayo, uze uhlahlele i-putty enganyangekiyo yamanzi. lubhelu.
Indlela yesi-3. Ziphephe iigesi zekhemikhali eziguqukayo kunye neziqhushumbisi. Ngexesha lenkqubo yokwakha, ngakumbi xa i-putty ingomile ngokupheleleyo emva kokwakhiwa, ungatshayi okanye ulayite umlilo ngaphakathi kwindlu ukuze ufudumale, kwaye ungasebenzisi iikhemikhali eziguquguqukayo ezifana nepeyinti kunye ne-thinners yayo ngaphakathi ngaphakathi kweenyanga ezintathu.
Indlela yesi-4. Gcina indawo ingena umoya kwaye yomile. Ngaphambi kokuba i-putty enganyangekiyo emanzini yome ngokupheleleyo, musa ukuvala iingcango kunye neefestile ngokuqinileyo, kodwa vula iifestile zokungenisa umoya, ukwenzela ukuba i-putty layer inokoma ngokukhawuleza.
Indlela yesi-5. Isixa esifanelekileyo se-462 elungisiweyo ye-ultramarine inokongezwa kwi-putty enganyangekiyo emanzini. Indlela ethile: Ngokomlinganiselo we-462 elungisiweyo ye-ultramarine: i-putty powder = 0.1: 1000, qala udibanise i-ultramarine kwisixa esithile samanzi, uvuselele ukunyibilika kunye nokucoca, yongeza isisombululo se-ultramarine yamanzi kunye namanzi kwisitya, uze ucinezele Amanzi ewonke: iputty powder = 0.5: 1 ubunzima bomlinganiselo, faka umgubo weputty kwisitya, udibanise ngokulinganayo kunye nomxube ukwenza ubisi olunekhrimu, uze ulusebenzise. Uvavanyo lubonisa ukuba ukongeza inani elithile le-ultramarine eluhlaza okwesibhakabhaka kunokuthintela umphezulu we-putty ekubeni ujike ube tyheli ukuya kwinqanaba elithile.
Indlela yesi-6. Kwi-putty ejike iphuzi, unyango lobugcisa luyafuneka. Indlela yonyango jikelele yile: qala ngokufaka i-primer kumphezulu weputty, kwaye emva koko ukhuhle kwaye usebenzise iputty enganyangekiyo yamanzi okanye ibrashi yangaphakathi yodonga lwepeyinti yelatex.
Shwankathela la manqaku angasentla:
Umphezulu otyheli weputty enganyangekiyo emanzini kunye nepeyinti yokulinganisa ye-porcelain ibandakanya iinkalo ezininzi ezifana nemathiriyeli ekrwada, iimeko zokusingqongileyo, iimeko zemozulu, isiseko sodonga, iteknoloji yokwakha, njl.
