Kuve yakakwirira-inoshanda synthetic resin, epoxy resin rave richishandiswa zvakanyanya munzvimbo dzakawanda dzehupenyu. Nekuda kwekunamira kwayo kukuru, kurwisa kukuru kwecorrosion, hunhu hwakasimba hwemagetsi, uye hukuru hwekupisa kupisa, ikozvino ndiyo yakanakira zvinhu munzvimbo yekudzivirira kwekuvhara. Pamusoro penzvimbo dzakawanda, inogona kupa chifukidziro chakasimba uye chakasimba chekudzivirira substrate kubva pakupfeka kwemuchina, kuora kwemakemikari uye kushanduka kwekushisa. Ingave simbi, kongiri, huni, plastiki uye mamwe maficha, inogona kupa yakanaka yekudzivirira iyo yekurebesa hupenyu hwesevhisi munzvimbo ine hutsinye.
Kunyangwe ichiita zvakanaka kwazvo mukudzivirira kwekuvhara, kubatsira kwayo kuchiri kutsamira pane imwe nzvimbo yekushandisa, mamiriro epamusoro uye tekinoroji maitiro. Nekuda kweizvozvo, kusarudzwa uye kushandiswa kwe epoxy resin kunoenderana nekuziva kwayo maficha uye mabhenefiti uye miganhu mukudzivirira kwekuvhara.
Zvimiro uye mabhenefiti epoxy resin padanho rekutanga
Muchinjikwa-unobatanidza epoxy mapoka uye anoomesa kuburikidza nemakemikari maitiro anoburitsa resin inogadzirwa. Hunhu hwayo hukuru isimba rakakura, kemikari inodzivirira kupisa, kunamatira kukuru, kukwirira kwemagetsi ekudzivirira, uye kugadzikana kwekushisa kwakasimba. Kutevera kurapa, inogona kupa yakasimba-dimensional-yakabatana-yakabatana network sisitimu ine yakanakisa tensile kuramba, kupfeka kuramba, uye compression kuramba kwezvinhu.
Epoxy resin ine mabhenefiti akajeka kwazvo maererano nekudzivirira kwekuvhara. Chekutanga pane zvese, inogona kuvaka homogeneous coating uye inonamatira zvine simba kumusoro kweakawanda substrates, kusanganisira simbi, kongiri, huni uye dzimwe nzvimbo. Chechipiri, inoratidza kuomarara kukuru uye kuomarara panguva yekurapa, izvo zvaizobatsira kutsungirira zvakakwana kukanganiswa kwemuviri, mavanga uye abrasion. Pakupedzisira, epoxy resin inodzivirira kemikari inoibatsira kuramba kukukurwa kwezvinhu zvakawanda zvinosanganisira acids, alkalis, munyu, zvinonyungudutsa, nezvimwewo, zvichiwedzera hupenyu hwesevhisi yesubstrate.
Kushandisa mune anti-corrosion protection
Inonyanya kushandiswa munharaunda yekudzivirira-corrosion kudzivirira. Zvakajairwa kuita ngura mumaindasitiri zvivakwa zvesimbi, kunyanya munzvimbo dzinotyisa semakungwa, zvidyarwa zvemakemikari, uye mapuratifomu emafuta, uko nzvimbo dzesimbi dzinoda kuchengetedzwa chaiko. Iyo yekupfekedza inogona kudzivirira kuita ngura, oxidation uye zvimwe zviitiko zvekuora pamwe nekunyatsoparadzanisa simbi kubva pakusangana nehunyoro, okisijeni uye mamwe makomba anoparadza. Kunyanya pamusoro pezvigadzirwa zvesimbi zvakaita semhangura, aruminiyamu alloy, uye simbi, iko kupfekedza hakungope dziviriro yemuviri asiwo kuwedzera hupenyu hwezvinhu izvi zvesimbi.
Munharaunda yegungwa, semuenzaniso, zvikamu zvesimbi zvinosanganisira mapuratifomu emafuta ekumahombekombe uye zvikepe zvinowanzoiswa mumvura yemunyu, mwando, asidhi uye alkaline makomponi. Iyo yekupfekedza inogona kuchengetedza zvakanyanya kuchengetedza uye kutsiva mutengo pamwe nekumisa zvakanaka mvura yemunyu kuti isaore pamusoro pesimbi. Muchikamu chemakemikari, migodhi uye magetsi zvakare, inogona kupa kuchengetedzwa kwenguva refu kwekudzivirira-kuora.
Kudzivirira chiito pane kongiri
Izvo hazvina basa chete kune zvigadzirwa zvesimbi asiwo zvakanyanya kushandiswa mukuchengetedza zvivakwa zvekongiri. Kwenguva yakareba, nzvimbo yekongiri inoiswa kune unyoro, asidhi, alkali uye mamwe makemikari, izvo zvinokonzeresa ngura uye peeling. Nechidziviriro chinoshanda chekudzivirira, iyo yekuputira inogona kubatsira kongiri kumisa kupinza kwehunyoro, chlorides uye makemikari ekuora, uye kudzikisira mwero wekongiri yekuora.
Migwagwa, mabhiriji, migero, zvivakwa zvepasi pevhu, uye mamwe mapurojekiti ekuvaka zvese zvinoenderana nekuputira kwayo kusapinda mvura uye kunopesana necorrosion kuwedzera hupenyu hwekongiri. Epoxy resin ndiyo yakakwana chinhu chekudzivirira mvura uye anti-corrosion muchikamu chekuvaka nekuti kune yayo anti-permeability uye chisimbiso hunhu. Uyezve kudzivirira nzvimbo yekrete kubva pakukuvadzwa kwemuviri ndiyo simba guru uye kupfeka kupikisa kwekuvhara.
Shandisa mukuchengetedza huni
Kunyangwe huni chiri chinhu chechisikigo chine hunyanzvi hwekuita uye chitarisiko, mwando, tupukanana, kuora, uye mwaranzi yeUV kazhinji inopesvedzera kutsungirira kwayo. Icho chinhu chepamusoro chekudzivirira chekudzivirira chinozobatsira hupenyu hwehuni huwedzerwe. Epoxy resin inoiswa pamusoro pehuni haingo wedzera kumira kwayo kweUV uye kusapinda kwemvura asi zvakare inopa imwe anti-corrosion dziviriro.
Iko kupfekedza kunogona kuderedza kupindira kwemvura uye kupinda kwezvipembenene, kumisa ganda rakasimba rekudzivirira kuburikidza nekupinda mukati mefibers yehuni, uye kubatsira huni kuti huputsika uye hunokanganisa zvishoma. Epoxy resin coating inogona kupa dziviriro yehuni kwenguva refu kunyanya pazvinhu zvematanda senge fenicha yekunze, madhishi engarava, uye dzimba dzemapuranga dzinofanirwa kugara dzichiratidzwa kune kunze nharaunda.
Kupokana nekupisa uye kumamiriro ekunze
Mune mamwe mamiriro ezvinhu, kupisa kupisa uye kuramba kwemamiriro ekunze kunotambawo basa rakakura rekudzivirira. Kazhinji ichiita zvakanaka pasi pekuchinja kwekushisa pakati pe60 ° C uye 150 ° C, yakajairwa epoxy resin inogona kushivirira tembiricha yepamusoro mukati mehumwe huwandu. Kunyanya kugadzirwa epoxy resins, mushure mekugadziridzwa, inogona kukwidziridza kupisa uye kutsungirira yakanyanya tembiricha mamiriro, izvo zvinoita kuti ishandiswe zvakanyanya mukudzivirira kuvhara munzvimbo dzemotokari, ndege, zvemagetsi uye zvemagetsi.
Uyezve, kupokana kwe epoxy resin kune zvinhu kunovimbisa kuvimbika kwayo munzvimbo dzekunze. Kunyangwe kupokana nemwaranzi yeUV kune mwero, kugona kwayo kuramba mwenje weUV inogona kuvandudzwa neakakodzera formula optimization kuitira kuti ikwanise kutamba basa rekudzivirira renguva refu munzvimbo dzine kupenya kwezuva kwakanyanya uye kusiyanisa kwakanyanya kwekushisa.
Maitiro ekushandisa Coatings:
Nepo kudzivirira kwekuvhara kune akawanda mabhenefiti, akati wandei matambudziko achiri kufanira kutariswa panguva yekushandiswa kwayo. Kutanga, iyo epoxy resin yekurapa maitiro inosanganisira imwe tembiricha uye humidity maitiro. Kurapa kwe epoxy resin kuchakanganiswa nekudzikira kwakanyanya uye hunyoro hwakanyanya; kunyangwe zvakadaro, zvinhu izvi zvinoburitsa pamusoro pemabhuru ekuputira kana kusaenzana. Chechipiri, epoxy resin coating ukobvu hunofanirwa kuve pasi pekutonga. Kunyanya kukora kwejasi kunogona kukonzera kusakwana kwekurapa, nekudaro zvichikanganisa kuomerera kwayo uye kusimba.
Kunze kwezvo, kugadzirira pamusoro kunoda mipimo yakasimba. Kuti uvimbise kuomerera kweiyo epoxy resin coating, pamusoro peiyo substrate inofanira kutanga isina ngura, yakachena, uye isina girizi. Kuti uvimbise hutano hwehuputi, zvakakoshawo kubvisa kupindira kubva kune zvakatipoteredza zvakasvibiswa panguva yekuvaka kwayo.
Kuchengetedza kwezvakatipoteredza uye kuchengeteka
Kunyange zvazvo ichi chiri chinhu chepamusoro-soro, kukoshesa kwevanhu kwagara kuri kunyanya kuchengetedza kwezvakatipoteredza uye kuchengetedza. Yechinyakare epoxy resin inosanganisira zvinonyungudutsa uye zvimwe zvinoputika organic komisheni (VOCs), saka kusangana kwenguva refu kunogona kukonzera mamwe matambudziko ehutano kumuviri wemunhu. Nekuda kweizvozvo, zviito zvekudzivirira zvakakodzera zvinofanirwa kuteverwa mukati mekuita kwekuvaka kwekuvhara: kupfeka masiki, magurovhosi, uye kuchengetedza mhepo yakanaka.
Sezvo kuziva kwezvakatipoteredza kwakawedzera mumakore achangopfuura, zvakanyanya uye zvakaderera-VOC epoxy resin zvigadzirwa zvakatanga kuratidza. Aya ecologically hushamwari epoxy resins ane zvimwe zvishoma kukuvadza nharaunda uye muviri wemunhu uye anobatsira kudzikisira kuburitswa kwemakomisheni ane njodzi. Kusarudza zvakatipoteredza epoxy resins haikodzeri chete kune maitiro ekusimudzira asi inobatsira kuwedzera kuchengetedzeka kwenzvimbo yekuvaka.
Epoxy resin yakashandiswa zvakanyanya muzvikamu zvakasiyana sechidziviriro chekuvhara nekuda kwekunamira kwayo kukuru, kusaita ngura, kuramba kupfeka, uye kuramba kupisa. Epoxy resin ine mabhenefiti akakosha angave ari mukudzivirira-kuora kwekudzivirira, kongiri pamusoro pekurapa, kuchengetedzwa kwehuni, kana mukupisa kwakanyanya uye hunyoro hwepamusoro. Kuti uvimbise kukanganisa uye kusimba kwenguva refu kwejasi, zvisinei, zvakakoshawo kufunga nezvemamiriro ekuvaka uye maitiro ezvakatipoteredza epoxy resin.
Iyo formula uye kuita kwe epoxy resin iri kuramba ichiwedzera sezvo sainzi uye tekinoroji inofambira mberi; kuunzwa kwezvakatipoteredza epoxy resin yakaratidza tarisiro itsva dzekushandisa. Icharamba yakakosha munzvimbo yekudzivirira kwekuvhara kuenda kumberi uye kupa zvinhu zvakasiyana zvakasimba, kuchengetedzwa kwenguva refu.
