1. I-Putty isetyenziswa njengesixhobo sokulungiswa komphezulu kwangaphambili ukuze igqunywe kwiingubo zokwakha.
I-Putty ngumaleko obhityileyo wodaka olulinganayo. I-Putty ikhutshiwe kumphezulu wesubstrates ezirhabaxa (ezifana nekhonkrithi, udaka lokulinganisa, ibhodi yegypsum, njl.njl.) Yenza umaleko wepeyinti yangaphandle ube mpuluswa kwaye ube-ethe-ethe, kungabi lula ukufumba uthuli kwaye kube lula ukuyicoca (oku kubaluleke ngakumbi kwiindawo ezinepeyinti ungcoliseko lomoya oluqatha). I-putty inokohlulwa ibe yi-putty yecandelo elinye (i-putty paste kunye ne-powder putty powder) kunye ne-putty yamacandelo amabini (enziwe nge-putty powder kunye ne-emulsion) ngokwefom yemveliso egqityiweyo. Ngokuqwalaselwa kwabantu kwitekhnoloji yokwakha yeengubo zokwakha, i-putty njengento ebalulekileyo yokuxhasa nayo iye yaphuhliswa ngokufanelekileyo. Abavelisi abahlukeneyo basekhaya baye baphuhlisa ngokulandelelana i-putty ngeenjongo ezahlukeneyo kunye neendlela ezahlukeneyo, ezinje ngepowder putty, i-paste putty, i-putty yodonga lwangaphakathi, i-putty yodonga lwangaphandle, i-elastic putty, njl.
Ukujonga kwisicelo sokwenyani sokwaleka kolwakhiwo lwasekhaya, kuhlala kukho izinto ezingeloncedo ezinje ngogwebu kunye nokuxobuka, nto leyo echaphazela kakhulu ukukhuselwa kunye nokusebenza komhombiso wokwaleka kwizakhiwo. Kukho izizathu ezibini eziphambili zomonakalo wefilimu yokugquma:
Omnye ngumgangatho wepeyinti;
Okwesibini kukuphathwa kakubi kwe-substrate.
Uqheliselo lubonise ukuba ngaphezu kwe-70% yokungaphumeleli kokugquma kuhambelana nokuphathwa kakubi kwe-substrate. I-Putty yokugquma i-architectural coatings isetyenziswe ngokubanzi njengemathiriyeli ekrwada yonyango lwangaphambili ukuze igqunywe. Ayinakugudisa kuphela kwaye ilungise umphezulu wezakhiwo, kodwa kunye ne-putty ekumgangatho ophezulu inokuphucula kakhulu ukhuseleko kunye nokusebenza komhombiso weengubo kwizakhiwo. Ukwandisa ubomi benkonzo yokugquma kuyimveliso eyimfuneko exhasayo yokwaleka komgangatho ophezulu wokusebenza, ngakumbi iingubo zodonga lwangaphandle. I-single-component dry powder putty ineenzuzo ezibonakalayo kwezoqoqosho, ezobuchwepheshe kunye nokusingqongileyo kwimveliso, ukuthutha, ukugcinwa, ukwakhiwa kunye nokunye.
Qaphela: Ngenxa yezinto ezinje ngemathiriyeli ekrwada kunye neendleko, umgubo wepolymer ohlakazekayo usetyenziswa ikakhulu kwi-anti-cracking putty powder kwiindonga zangaphandle, kwaye ikwasetyenziswa kwi-high-grade yangaphakathi yokupolisha iputty.
2. Indima ye-anti-cracking putty kwiindonga zangaphandle
I-putty yodonga lwangaphandle ngokuqhelekileyo isebenzisa i-samente njenge-inorganic bonding material, kunye nenani elincinci le-ash calcium linokongezwa ukufezekisa umphumo we-synergistic. Indima ye-samente-based anti-cracking putty kwiindonga zangaphandle:
I-surface layer putty ibonelela ngesiseko esihle, esinciphisa inani lepeyinti kunye nokunciphisa iindleko zeprojekthi;
I-Putty ine-adhesion eyomeleleyo kwaye inokudityaniswa kakuhle eludongeni lwesiseko;
Inobulukhuni obuthile, inokuthintela kakuhle isiphumo sokwandiswa okwahlukeneyo kunye noxinzelelo lokucutheka lweeleya ezahlukeneyo zesiseko, kwaye inokumelana nokuqhekeka okulungileyo;
I-Putty inokumelana nemozulu elungileyo, ukunganyameki, ukuxhathisa ukufuma kunye nexesha elide lenkonzo;
Ikhuselekile kokusingqongileyo, ayinabungozi kwaye ikhuselekile;
Emva kohlengahlengiso lwezongezo ezisebenzayo, ezinje ngomgubo werabha ye-putty kunye nezinye izinto, i-putty yodonga lwangaphandle lunokuba nezi nzuzo zilandelayo:
Umsebenzi wokukrala ngokuthe ngqo kwizinto zakudala ezigqityiweyo (ipeyinti, i-tile, i-mosaic, ilitye kunye nezinye iindonga ezigudileyo);
I-thixotropy elungileyo, indawo ephantse igqibelele egudileyo inokufunyanwa ngokuthambisa nje, kwaye ilahleko ebangelwa kukusetyenziswa kwezinto ezininzi zokugquma ngenxa yomgangatho ongalinganiyo wesiseko uyancitshiswa;
I-elastic, inokuxhathisa i-micro-cracks, kwaye inokuphelisa umonakalo woxinzelelo lobushushu;
Ukugxotha kakuhle kwamanzi kunye nomsebenzi ongenamanzi.
3. Indima ye-latex powder ephinda ihlakazwe kwi-putty eludongeni lwangaphandle
(1) Isiphumo somgubo werabha oyiputty kwiputty esandula kuxutywa:
Ukuphucula ukusebenza kunye nokuphucula ukusebenza kwe-putty batch scraping;
ukugcinwa kwamanzi okongeziweyo;
ukwanda kokusebenza;
Kuphephe ukuqhekeka kwangoko.
(2) Isiphumo somgubo werabha oyiputty kwiputty eqinileyo:
Ukunciphisa i-elastic modulus ye-putty kwaye uphucule ukuhambelana nomgangatho wesiseko;
Ukuphucula i-micro-pore isakhiwo se-samente, ukwandisa ukuguquguquka emva kokufaka i-putty rubber powder, kwaye uxhathise ukuqhekeka;
Ukuphucula ukumelana nomgubo;
I-Hydrophobic okanye ukunciphisa ukufunxa kwamanzi kwi-putty layer;
Ukwandisa ukunamathela kwe-putty eludongeni lwesiseko.
Okwesine, iimfuno zenkqubo yokwakhiwa kwe-putty eludongeni lwangaphandle
Inkqubo yokwakha i-putty kufuneka ithathele ingqalelo:
1. Impembelelo yeemeko zokwakha:
Impembelelo yeemeko zokwakha ubukhulu becala liqondo lobushushu kunye nokufuma kokusingqongileyo. Kwiindawo ezishushu, isiseko sesiseko kufuneka sitshizwe ngokufanelekileyo ngamanzi, okanye sigcinwe simanzi, kuxhomekeke ekusebenzeni kwemveliso ethile ye-putty powder. Ekubeni i-putty yodonga lwangaphandle lusebenzisa i-samente njengesixhobo se-cementitious, ubushushu be-ambient kufuneka bungabi ngaphantsi kwe-5 degrees, kwaye abuyi kuba ngumkhenkce ngaphambi kokuqina emva kokwakhiwa.
2. Amalungiselelo kunye nezilumkiso phambi kokukrazula iputty:
Kufuneka ukuba iprojekthi eyintloko igqitywe, kwaye isakhiwo kunye nophahla zigqityiwe;
Zonke iindawo ezidibeneyo, iingcango, iifestile kunye nemibhobho yesiseko somlotha kufuneka ifakwe;
Ukuthintela ukungcoliseka kunye nomonakalo kwiimveliso ezigqityiweyo kwinkqubo ye-batch scraping, izinto ezithile zokukhusela kunye namanyathelo kufuneka zinqunywe ngaphambi kokuba i-batch scraping, kwaye iindawo ezifanelekileyo kufuneka zifakwe kwaye zihlanganiswe;
Ukufakwa kwefestile kufuneka kuqhutywe emva kokuba i-putty batch ikhutshiwe.
3. Unyango lomphezulu:
Umphezulu we-substrate kufuneka uqine, ucwecwe, womile kwaye ucoceke, ukhululekile kwigrisi, i-batik kunye nezinye izinto ezikhululekile;
Umphezulu we-plastering entsha kufuneka uphiliswe iintsuku ezili-12 ngaphambi kokuba i-putty ikhutshwe, kwaye i-original layering layering ayinakulinganiswa nge-cement paste;
Ukuba udonga lome kakhulu ngaphambi kokwakhiwa, udonga kufuneka lumanziswe kwangaphambili.
4. Inkqubo yokusebenza:
Galela umlinganiselo ofanelekileyo wamanzi kwisitya, uze udibanise i-putty powder eyomileyo, uze udibanise ngokupheleleyo ngomxube kuze kube yintlama efanayo ngaphandle kwamasuntswana empuphu kunye nemvula;
Sebenzisa isixhobo se-batch scraping kwi-batch scraping, kwaye i-batch scraping yesibini inokuqhutywa emva kokuba umaleko wokuqala we-batch embedding ugqityiwe malunga neeyure ze-4;
Khupha umaleko weputty kakuhle, kwaye ulawule ubukhulu bube malunga ne-1.5mm;
I-putty esekelwe kwi-samente inokupeyintwa nge-primer enganyangekiyo ye-alkali kuphela emva kokuba ukunyanga kwendalo kugqityiwe de i-alkalinity kunye namandla ahlangabezane neemfuno;
5. Amanqaku:
Ukuma kunye nokuqina kwe-substrate kufuneka kumiselwe phambi kokwakhiwa;
Udaka oluxutyiweyo lwe-putty kufuneka lusetyenziswe ngaphakathi kwe-1 ~ 2h (kuxhomekeke kwifomula);
Musa ukuxuba udaka lwe-putty olugqithise ixesha lokusetyenziswa kwamanzi ngaphambi kokuwusebenzisa;
Kufuneka ikhazimliswe ngaphakathi kwe-1 ~ 2d;
Xa umgangatho wesiseko ubalwa nge-cement mortar, kuyacetyiswa ukuba usebenzise i-arhente yonyango lwe-interface okanye i-interface putty kunye ne-elastic putty.
Umthamo wei-polymer powder enokuchithwa kwakhonaingabhekisa kwidatha yedosi kwifomula yeputty eludongeni lwangaphandle. Kuyacetyiswa ukuba abathengi baqhube iimvavanyo ezininzi ezahlukeneyo zesampulu ngaphambi kokuveliswa kobuninzi ukuqinisekisa umgangatho weputty powder.
