Chinangwa cheCoating Zvinhu
Kucherekedza kunze kwekunze kwemapepa echibwe akakosha kuti udzivirire kuchinjika. Kubhururuka pamusoro pechipfeko chesimbi kunogona kukanganisa zvakanyanya kushanda kwavo, mhando, uye kutaridzika kwekuona. Nekudaro, maitiro ekubatanidza ane maitiro anokanganisa pane zvese mhando yezvinhu zvesimbi zvigadzirwa zvigadzirwa.

Zvinodiwa zveCoating Zvekushandisa
Sezvineiwo pamitemo yakaiswa neAmerican Petroleum Institute, mapepa esimbi anofanira kuramba kuonga kwemwedzi yakati wandei. Nekudaro, iyo inodiwa kwenguva refu anti-denderedzwa nguva dzawedzera, nevashandisi vazhinji vanoda kuramba kwemwedzi mitatu kusvika matanhatu mumamiriro ekunze ekunze ekuchengetedza. Kunze kweiyo longethity zvinodiwa, vashandisi vanotarisira marara kuti varambe vakatsetseka, kunyange kugovera vamiriri veAnti-vanokosheswa vasina kana drips kana kudonha izvo zvinogona kukanganisa hunhu.

Mhando dzekubatanidza zvigadzirwa uye yavo zvakanaka uye cons
MuHurban pasi pevhu pombi network,masimbi mapipivari kuwedzera kushandiswa kwekutakura gasi, mafuta, mvura, uye zvimwe. Zvipfeko izvi zvibayiro izvi zvakashanduka kubva kune yechinyakare asphalt zvigadzirwa kuPolyethyle resin uye epoxy resin zvinhu. Kushandiswa kwePolyethyle Resin COatings kwakatanga muma1980s, uye nekunyorera kwakasiyana, zvikamu uye maitiro ekubatanidza akaona kuvandudzwa zvishoma nezvishoma.
3.1 petroleum asphalt coating
Petroleum Asphalt Coating, Chinyakare chinwiwa-chinokatyamadza, chine peturu asphalt laers, inosimbiswa nejira refuti uye yekudzivirira kwekuchengetedza polyvinill chloride firimu. Iyo inopa mvura yakanakisa, yakanakisa kudiwa kune dzakasiyana-siyana nzvimbo, uye mutengo-kushanda. Nekudaro, iyo ine madhiragi zvinosanganisira kushamwaridzana nekushambadzira kwekushisa, kuve brontle mukuwedzera kupisa, uye kuve nekukwegura uye kupaza, kunyanya mumatombo ivhu, kudarika mamwe maitiro ekudzivirira uye akawedzera mari.
3.2 Coal Tar Epoxy Coating
Coalar tar epoxy, yakagadzirwa neye ePoxy resin asphalt, inoratidzira mvura yakanakisa uye yemakemikari kurwisa, kusimba kwakanaka, simba rekusimba, uye insolation. Nekudaro, zvinoda kugara kwenguva refu kuporesa nguva yekutumira-application, ichiita kuti isingakanganiswe nemhedzisiro yakaipa kubva kumamiriro ekunze panguva ino. Uyezve, matunhu akasiyana siyana anoshandiswa mune ino yekubatanidza system inoda kuchengetwa kwakasimba, kurera mari.
3.3 EPOXY POWDER Kuunganidza
EPOXY POWEDER Coating, yakaunzwa muma1960s, inosanganisira yakasarudzika yekupuruzira poda pane pre-yakarapwa uye pipi pipi pipi nzvimbo, achiumba dense anti-controsival denderedzwa. Zvakanakira zvarinzvisanganisira tembiricha yakajeka (-60 ° CE kusvika 100 ° C), kuamatira kwakasimba, kuramba kwakanaka kuCathodic kusazvipira, kukanganisa, nekukasira, uye tel. Nekudaro, firimu rayo rakaonda rinoita kuti riwedzere kukuvadza uye rinoda nzira dzakasarudzika dzekugadzira uye michina, zvinongedzo mumunda wekushandisa. Kunyange zvichidaro mune zvakawanda zvikamu, zvinopera kupfupika polyethylene maererano nekupisa kupesana uye nekuwedzera kudzivirirwa.
3.4 Polyethyle anti-controsives coating
Polyethyle inopa yakanyanya kukanganisa kuramba uye kuomesa kwakanyanya pamwe chete neyakaipisisa tembiricha. Inowana yakawanda yekushandisa munzvimbo dzinotonhora senge Russia uye Western Europe yePipelline nekuda kwekushanduka kwayo uye kukanganisa, kunyanya kudziya kwakadzika. Nekudaro, matambudziko anoramba ari muchirongwa charo pamapakero akakura-dombo, uko kupaza kwemvura kunogona kuitika, uye kurira kwemvura kunogona kutungamira kuCorros pasi pekuchera, kuwedzeredza kutsvagisa uye kugadzirisa mune zvekushandisa uye maitiro ekushandisa uye maitiro ekushandisa.
3.5 Anorema Anti-Corrosion Coating
Zvipfeko zvinorema zveAnti-Corrosion zvinopa zvakanyanya kuvandudza kurwisa kupesana kunoenzaniswa neyakajairwa machira. Vanoratidza kushanda kwenguva refu kunyange mumamiriro ezvinhu akaomarara, vane makore mazhinji vanopfuura makore gumi kusvika gumi nemashanu mumakemikari, marine, uye anopfuura makore mashanu mune acidic, orgaline, kana mamiriro emaruwa. Izvi zvejasi kazhinji vane dzakaoma dzakaoma dziva kubva ku2003 kusvika pa2003 kusvika 2000μm, ichiratidza kudzivirirwa kwakakwirira uye kusimba. Ivo vanoshandiswa zvakanyanya mumidziyo yemarine, zvigadzirwa zvemakemikari, matangi ekuchengetedza, uye matanda.

Zvakajairika Zvinyorwa Zvekubatanidza Zvinyorwa
Nyaya dzakajairika nejasi dzinosanganisira kushanda zvisina kufanira, kudonha kwevashandi vekudzivirira, uye kuumbwa kwemabubble.

Kuongororwa kwekubatanidza nyaya dzemhando yepamusoro
Dambudziko rega rega rinomuka kubva kuzvikonzero zvakasiyana siyana, rinokonzerwa nezvinhu zvakasiyana; Uye bhandi renguruve renel rakaratidzwa nemhando yedambudziko rinogona kuvewo musanganiswa wehuwandu. Izvo zvinokonzeresa kuunganidza zvisina kufanira kunogona kukakamurwa kuita zvakaringana kuita marudzi maviri, chimwe chikamu chisina kufanana chinokonzerwa nekupfira mushure mekunge chimbi chesimbi chinopinda mubhokisi rekubatanidza. Yechipiri ndiyo chisungo chisina kuenzana chakakonzerwa nekusapuruzira.
Chikonzero chekutanga chiitiko chiri nyore kuona, kumidziyo yekubatanidza apo iyo pombi iri mubhokisi rekubatanidza mu 360 ° kutenderera kwepfuti 6 Kana pfuti imwe neimwe yakapfava kubva kuhukuru hwekuyerera yakasiyana, ipapo ichatungamira pakugoverwa zvisina kujairika kweanopokana mumiririri munzvimbo dzakasiyana-siyana dzepombi yesimbi.
Chikonzero chechipiri ndechekuti pane zvimwe zvikonzero zvekuverengeka kuunganidza phenomenon kunze kwekupuruzira. Kune marudzi mazhinji ezvinhu, senge pombi yesimbi inouya, roughness, kuitira kuti kuunganidzira kwakaoma kugovaniswa. Simbi pombi pamusoro pechiyero chemvura chakasiyiwa kana emulsion, panguva ino yekubatira pamusoro pekusangana kwepombi.
(1) Chikonzero chevatambi vanorembera madonhwe. Muchikamu-chikamu chengarava chakakomberedzwa, pese pese pakapindirwa mumuromo wechipfuva chesimbi, muenzanisirwo unoyerera muchikamu chepasi nekuda kwechinhu chakakura, icho chinozoumba chidimbu chekudonha kwekurembera. Chinhu chakanaka ndechekuti kune oven zvigadzirwa mukubatanidza mutsara weiyo simbi pombi fekitori, iyo inogona kusimbisa mumiririri wekupfekedzwa pamusoro penzvimbo yesimbi munguva uye kuderedza iyo fluidity yeiyo anticorriswe mumiriri. Nekudaro, kana visikoka yeanofungidzira mumiririri asina kukwirira; Hapana kudziya nguva mushure mekupfira; kana kupisa kupisa hakuna kukwiririsa; Iyo nozzle haina kumira zvakanaka mamiriro, etc. ichaendesa kune iyo yekufungidzira mumiririri akarembera.
(2) Zvinokonzeresa kupupurira kunofungidzira. Nekuda kwenzvimbo yekushandisa saiti yeMhepo Humidity, pendi kupararira kwakawandisa, kupararira kuita tembiricha yekudziya ichakonzera kuchengetedza phenomenon. Mhepo yakanyoroveswa nharaunda, yakadzika tembiricha mamiriro, inochengetedza inopararira kubva kune yakapararira mumatiki madiki, ichatungamira kudonhedza mukushisa. Mvura iri mumhepo ine humbozha mushure mekudzora kwekudziya kuchawedzera kuumba madonhwe emvura akasanganiswa neinochengetedza, uye anozopedzisira apinda mukati mekurongedza, zvichikonzera kuunganidza phenomenon.
