Kupanga ufa wamtengo wapatali wa putty kumafuna kumvetsetsa katundu wake ndikuwonetsetsa kuti ikugwirizana ndi machitidwe ena ndi ntchito.Putty, yemwe amadziwikanso kuti wall putty kapena wall filler, ndi ufa wonyezimira wa simenti wonyezimira womwe umagwiritsidwa ntchito kudzaza zilema pamakoma opusidwa, pamalo a konkriti ndi zomangamanga asanapente kapena kupaka mapepala.Ntchito yake yayikulu ndikuwongolera malo, kudzaza ming'alu ndikupereka maziko oti apente kapena kumaliza.
1. Zosakaniza za putty powder:
Binder: Chomangira mu putty powder nthawi zambiri chimakhala ndi simenti yoyera, gypsum kapena osakaniza awiriwo.Zida zimenezi zimapereka kugwirizanitsa ndi kugwirizana kwa ufa, zomwe zimalola kuti zigwirizane ndi pamwamba ndikupanga mgwirizano wamphamvu.
Zodzaza: Zodzaza monga calcium carbonate kapena talc nthawi zambiri zimawonjezeredwa kuti zisinthe mawonekedwe ndi kuchuluka kwa putty.Zodzaza izi zimathandizira kuti zinthu zizikhala zosalala komanso zogwira ntchito.
Zosintha / Zowonjezera: Zowonjezera zingapo zitha kuwonjezeredwa kuti zithandizire kukulitsa mawonekedwe a putty powder.Zitsanzo zikuphatikizapo ma cellulose ethers kuti apititse patsogolo kusungirako madzi ndi processability, ma polima kuti awonjezere kusinthasintha ndi kumamatira, ndi zotetezera kuteteza kukula kwa tizilombo toyambitsa matenda.
2. Zofunikira za ufa wa putty:
Fineness: Putty ufa uyenera kukhala ndi tinthu ting'onoting'ono tomwe timapangitsa kuti ntchito ikhale yosalala komanso yofanana pamwamba.Fineness imathandizanso ndi kumamatira bwino komanso kudzaza zolakwika.
Kumamatira: Putty ayenera kumamatira bwino ku magawo osiyanasiyana monga konkriti, pulasitala ndi zomangamanga.Kumamatira mwamphamvu kumatsimikizira kuti putty imamatirira pamwamba ndipo sichidzagwedezeka kapena kusenda pakapita nthawi.
Kugwira ntchito: Kugwira ntchito bwino ndikofunikira kuti mugwiritse ntchito mosavuta komanso kupanga putty.Iyenera kukhala yosalala komanso yosavuta kugwiritsa ntchito popanda kuyesetsa kwambiri, kudzaza ming'alu ndi mabowo bwino.
Kukana kwa Shrinkage: Putty ufa uyenera kuwonetsa kuchepa pang'ono pamene ukuuma kuti zisapangike ming'alu kapena mipata mu zokutira.Kutsika kochepa kumatsimikizira kutha kwa nthawi yayitali.
Kukaniza Madzi: Ngakhale ufa wa putty umagwiritsidwa ntchito m'nyumba, uyenera kukhala ndi mulingo wina wamadzi kuti usavutike ndi chinyezi komanso chinyezi popanda kuwonongeka.
Nthawi yowumitsa: Nthawi yowuma ya ufa wa putty iyenera kukhala yomveka kuti kujambula kapena kumaliza ntchito kutha panthawi yake.Njira zoyanika mwachangu ndizofunikira kuti polojekiti isinthe mwachangu.
Mchenga: Ukawuma, putty ayenera kukhala mchenga wosavuta kuti apereke malo osalala, osalala kuti apente kapena kupaka mapepala.Kukhazikika kwa mchenga kumathandizira kuti pakhale mawonekedwe abwino komanso mawonekedwe.
Crack Resistance: Ufa wapamwamba kwambiri wa putty uyenera kukhala wosagwirizana ndi kusweka, ngakhale m'malo omwe kusinthasintha kwa kutentha kapena kusuntha kwamapangidwe kumatha kuchitika.
Kugwirizana ndi utoto: Putty ufa uyenera kukhala wogwirizana ndi mitundu yosiyanasiyana ya utoto ndi zokutira, kuonetsetsa kuti kumamatira koyenera komanso kukhazikika kwa nthawi yayitali kwa topcoat system.
Low VOC: Kutulutsa kosasunthika kwa organic compound (VOC) kuchokera ku ufa wa putty kuyenera kuchepetsedwa kuti muchepetse kuwonongeka kwa chilengedwe ndikusunga mpweya wabwino wamkati.
3. Miyezo yaubwino ndi kuyezetsa:
Kuonetsetsa kuti ufa wa putty ukukwaniritsa zofunikira zogwirira ntchito ndi magwiridwe antchito, opanga nthawi zambiri amatsatira malamulo amakampani ndikuyesa mozama.Njira zodziwika bwino zowongolera zabwino ndi izi:
Kusanthula kukula kwa tinthu ting'onoting'ono: Kuyesa kusalala kwa ufa pogwiritsa ntchito njira monga laser diffraction kapena sieve kusanthula.
Kuyesa kumamatira: Unikani mphamvu yomangirira ya putty ku magawo osiyanasiyana kudzera pakuyesa kukoka kapena kuyesa kwa tepi.
Kuwunika kwa Shrinkage: Yesani kusintha kwa mawonekedwe a putty panthawi yowumitsa kuti muwone mawonekedwe a shrinkage.
Kuyesa Kulimbana ndi Madzi: Zitsanzo zimayesedwa kumizidwa m'madzi kapena kuyesedwa m'chipinda cha chinyezi kuti ayese kukana chinyezi.
Kuyanika kwa nthawi yowumitsa: Yang'anirani momwe kuyanika kumayendera mokhazikika kuti muwone nthawi yofunikira kuti machiritso achire.
Kuyesa kwa Crack Resistance: mapanelo okutidwa ndi putty amakumana ndi zovuta zofananira zachilengedwe kuti aunikire mapangidwe ndi kufalikira kwa ming'alu.
Kuyesa Kuyanjanitsa: Unikani kugwirizana ndi utoto ndi zokutira poziyika pa putty ndikuwunika kumamatira ndi kumaliza.
Kusanthula kwa VOC: Kuwerengera zotulutsa za VOC pogwiritsa ntchito njira zokhazikika kuti zitsimikizire kutsatiridwa ndi malire.
Potsatira miyezo yapamwambayi ndikuyesa mozama, opanga amatha kupanga ma putties omwe amakwaniritsa zofunikira zogwirira ntchito ndikupereka ntchito yodalirika pakupanga ndi kumaliza ntchito zosiyanasiyana.
Makhalidwe a putty powder ndi otero kuti amadzaza bwino zolakwika ndipo amapereka malo osalala kuti azijambula kapena kumaliza.Opanga ayenera kuganizira mozama kapangidwe kake ndi kapangidwe ka ufa wa putty kuti awonetsetse kuti akuwonetsa zinthu zofunika monga kumamatira, kugwirira ntchito, kukana komanso kulimba.Potsatira miyezo yabwino komanso kuyesa mwamphamvu, ufa wapamwamba wa putty umapangidwa kuti ukwaniritse zosowa za akatswiri omanga ndi eni nyumba.
