Kupfeka kunobuda mumvurandiyo mhando huru kwazvo yetekinoroji yekuputira inoshandiswa pasi rose uye inotarisirwa kuramba ichikura sechikamu chimwe chete kubva muzana chemusika wese wekuputira. Panosvika gore ra2022,saizi yemusika wepasi roseyependi yemvura inotarisirwa kudarika mabhiriyoni zana nemakumi mana nematanhatu emadhora ekuAmerica. Kukura kwacho kwakanyanya kunokonzerwa nekuwedzera kwehuwandu mumisika yekuvaka nemotokari inema acryliciri rudzi rumwe chete rukuru rwemhando ye resin inoburitswa mumvura inomiririra inopfuura 80% yemusika wese unoburitswa mumvura.

Iyi iAthena.MIT-IVY INDUSTRY inonyanya kuita pendi yemaindasitiri inogadzirwa nemvura, ndinoziva kuti munoda zvigadzirwa zvemhando yepamusoro, zvine mutengo wakaderera uye zvekutsigira tekinoroji, tine ISO certification, kunyanya katalogi yezvigadzirwa ine mutengo. Isu tinotenda chete mumhando yepamusoro,

Uye mukugutsikana kwevatengi vedu. Kana muchida kubvunza, ndapota taurai neni. ️ Taurai Nesu:

Masimba ekutyairaKuwedzera kushandiswa kwezvipfeko zvinobuda mumvura zvinosanganisira:

• VOC Yepasi
• Zviri nyore kuchenesa muzviitiko zvakawanda
• Kuderera kwenjodzi yemoto
• Mari yakaderera yeinishuwarenzi
• Kushandiswa kwesimba shoma kwemachira akabikwanekuda kwekudiwa kwemhepo shoma yekuzora muchoto
• Kudiwa kwekudzikira kwemazinga epeturu-zvinhu zvakagadzirwa.

Sezvakanyorwa muna Chivabvu, 2014 muProspector pamusoroKuyerera, Kuenzana uye Kudzora Kusviba muMachira Akavakirwa Pamvurazvinoratidza kuti, mapoka maviri makuru ezvipfeko zvinopfekwa nemvura zvinosanganisirainoderedzwa mvurauyelatex, neruzhinji rwemachira akabikwa ari muchikamu chekutanga, mazhinji emachira ekuvaka ari muchikamu chechipiri. Izwi iriinoderedzwa mvurainoshandiswa kumaresini akagadzirwa nemusanganiswa wemvura uye akaderedzwa mumvura kuti agadzire kupararira kweresini mumvura.Latexkune rumwe rutivi, maresini anogadzirwa ne emulsion polymerization mumvura.

Zvakashata zvekushandisa machira ekudzivirira anoburitswa mumvura zvinosanganisira:

• Kutsamira kwakanyanya kwehuwandu hwemvura inobuda mumhepo (evaporation rate) pahunyoro hwemhando yepamusoro
• Kupisa kwakanyanya kwemvura kunoda 2260 J/g yemvura uye semuenzaniso 373 J/g chete yemvura.2-butoxyethanol, chinhu chinowanzoshandiswacosolvent
• Nzira yekuderedza viscosity isina kurongeka yekupenda uchishandisa maresini anodzikisa mvura
• Kuvimba zvakanyanya nekuyerera uye chitarisiko chehunyoro
• Kukwirira kwemvura pamusoro (kunyorova kushoma) kunoda kuwedzerwa kwezvinhu zvinoshandisa masurfactantizvo muzviitiko zvakawanda zvinoderedza kuramba kwehunyoro
• Mapendi emvura anoparadza zvakanyanya kupfuura mapendi emvura anonyungudika saka anoda magaba ane jira, mapurasitiki kana simbi isina ngura kudzivirira ngura.
• Mapendi anobuda mumvura anowanzo buda muzvishandiso zvakabikwa sezvo firimu rinotanga kugadzirwa mvura isati yapera kubva mufirimu (ona Tafura I)

Zvisinei, kufambira mberi kuri kuramba kuripo musainzi yezvinhu kunosanganisira hunyanzvi mu resin chemistry, surfactants,zvinhu zvinonyorovesauyezvinhu zvinofambisa mvurazvichabatsira kuti machira anoputirwa nemvura arambe achikura.

Mufananidzo wekutanga unomiririra matanho akasiyana-siyana ekuomeswa kwependi yakagadzirwa ne latex. Danho rekutanga rinosanganisira kubuda kwemvura. Danho rechipiri rinosanganisira kubuda kwemvura ne cosolvent kusvika panosvika zvidimbu zve latex zvinobatana zvotanga kubatana kuti zvigadzire firimu rinooma zvishoma.

Danho rekupedzisira rinosanganisira kuramba uchibatana uye kupora (muhurongwa hwakabatana) kuti pave nependi yakapfava uye yakaoma inonamatira.

Chimwe chezvinhu zvakakosha pakushandisa machira ekudzivirira anobuda mumvura ibasa rakawedzerwa rinoitwa nehunyoro pamwe chete nekupisa mukushandiswa uye kugadziriswa kwemachira aya. Semuenzaniso, kuti zvive nehunhu hwakanaka hwekushandisa, tembiricha nehunyoro zvinofanirwa kudzorwa nokungwarira sezvakaratidzwa muMufananidzo II. Mhedzisiro yehunyoro pamachira ane mvura-organic solvent haigone kufuratirwa.

Semuenzaniso, mwero wekubuda kwemvura (E) wemvura pa0 - 5% RH pa25°C i0.31, asi pa100% RH i0. E ye2-butoxyethanol, cosolvent inowanzoshandiswa, i0.077. PaRH yakaderera, mvura inobuda nekukurumidza uye nokudaro chiyero che2-butoxyethanol nemvura chinowedzera; zvakapesana ndezvechokwadi kana hunyoro hwakawanda.

Kana machira anoputirwa nemvura akaiswa, kana hunyoro hukasatariswa, kuchinja kwehunhu hwekushandisa uye chitarisiko zvichaitika. Semuenzaniso kana tembiricha pakushandiswa gore rose iri 70° – 80° F, kushandiswa kwakaoma (kurasikirwa nekuyerera) kuchaguma nemwedzi yechando nekuda kwehunyoro hushoma kunyanya munzvimbo dzinotonhora uye kuyerera kwakawanda kuchaonekwa mumwedzi yezhizha (hunyoro hwakawanda). Muenzaniso wemamiriro ezvinhu anotevera ndewekuti paanenge 65% Hunyoro/25 °C, chifukidziro chinoputirwa nemvura chine 10.6% 2-butoxyethanol ye volatiles, mwero wemvura unobuda uye 2-butoxyethanol zvakaenzana. Hunyoro uhwu hunonzi Hunyoro Hunoputirwa Nemvura ...

Mufananidzo II Kushandiswa kweMachira Anobuda Mumvura Kunoenderana neHumidity neTembiricha.

Tafura I inoratidza kuwedzera kwekushandiswa kwezvipfeko zvinobuda mumvura pakukora kwakasiyana-siyana kwefirimu kana zvichienzaniswa nezvipfeko zvinobuda mumvura.

Tafura I Kukobvu Kwemafirimu Akakosha Ekuti Abude MumaMicron, Organic Coatings, Wiley-Interscience, 2007, Zeno W. Wicks Jr., Frank N. Jones, S. Peter Pappas, Douglas A. Wicks

Mapendi emvura anosanganisira mhando dzakasiyana dze resin dzakadai seacrylic,alkyd,urethane,polyester,epoxy,fluoropolymer, hupfu hwemvura pamwe chete nemakemikari ekurapa anosanganisiraMushonga weUV,aminoplast, urethane,epoxy-polyamide,oxidativeuyethermoplastic yakaoma nemhepomhando. Sezvinoratidzwa neTafura II, saizi yezvikamu uye magadzirirwo ezvikamu (semuenzaniso goko guru) zvinobatsirawo pakugadzirwa kwefirimu repamusoro.
