Corrosion resistant simbi pombi mugadziri
Anticorrosive simbi pombi inoreva pombi yesimbi inogadziriswa neanticorrosive process, inogona kudzivirira kana kudzikisa pasi chiitiko chekuora chinokonzerwa nekemikari kana electrochemical reaction panguva yekufambisa uye kushandiswa. Zvinoenderana neChina nhamba yedata, kurasikirwa kwakananga kwehupfumi kwesimbi pombi corrosion muChina kunodarika 280 bhiriyoni gore rega rega.
Parizvino, kurasikirwa kwepagore kwepasirese nekuda kwekuora kwepombi yesimbi kwakakwira semadhora mazana mashanu emadhora ekuAmerica. Anticorrosive simbi pombi inogona kunyatso kudzivirira kana kudzikisa ngura, kurebesa hupenyu hwebasa repombi yesimbi uye kuderedza mutengo wekushanda wepombi yesimbi.
Composition
Inoumbwa nealiphatic polyurethane prepolymer, epoxy resin, pigment yemhando yepamusoro, zvinowedzera uye zvinonyungudutsa. Inonyanya kushandiswa anti-corrosion yemidziyo inosangana nechikafu nemvura yekunwa, kutapurirana kwemvura uye kugovera pombi uye yekunwa tangi remvura.
Performance
Iyo pendi ndeyehunyanzvi inopindirana network polymer, iyo inotanga polymerization pakamuri tembiricha. Iwo maviri network anogona kudzidza kubva kune mumwe nemumwe uye kuburitsa cooperative effect. Iyo firimu haina-chepfu, yakakwirira yakasimba uye yakaderera viscosity. Iyo itsva anti-corrosion coating ine yakasimba adhesion, yakakwirira simba, kukanganisa kupfeka kuramba, hydrolysis resistance, corrosion resistance, kudzivirira mvura uye kuramba kwemamiriro ekunze, uye ine zvakaderera zvinodiwa pakubvisa ngura pamusoro pesimbi chimiro, Tembiricha yebasa inogona muhuwandu hwe -20 ~ 120 ℃.
Technical zviratidzo
1. Nguva yekuomesa: kuomeswa kwepamusoro kwe30min uye kuoma kwakasimba kwe6-24h
2. Kuchinja: 1mm
3. Impact kuramba: 50cm
4. Kunamatira: Giredhi 1
4. Kuvaka uye kuchengetedza
(1)Pamberi pekupenda, pamusoro pesimbi yepasi ichabatwa kuSa2.5. Izvo zvinorambidzwa zvachose kuunza mvura, guruva nemafuta panguva yekuvaka kuti ive nechokwadi chekupenda.
(2) Chiyero chekuputira ndeichi: chikamu a (base zvinhu), chikamu B (chirapa mumiririri) = 9kg pendi: 1kg yekurapa mumiririri (kana kuvaka zvinoenderana nechikamu chinoziviswa nefekitori yedu).
(3)Nzira yekuenzanisa yekuvaka yakaita seiyi: vhura kuvhurwa kukuru kwechikamu A, wedzera chikamu B muchikamu A, uye zvizere sanganisa zvakaenzana. Mushure mekuporesa kwemaminitsi makumi matatu, kuvhara kunogona kuitwa.
(4)Ichi chinyorwa chinodiwa kuti chigadziriswe uye chishandiswe chero nguva, uye yakaenzana coating inofanira kushandiswa mukati maawa matanhatu. Zvinhu zvisina kupera zvichavharwa nekuchengetwa.
(5)Kuvaka kuchamiswa mumazuva ekunaya kwemvura kana kuti hunyoro hunopfuura 75%. Kune zvikamu zvine corrosive medium, zvinokurudzirwa kushandisa majasi akawanda epende.
(6) Chigadzirwa chacho chinofanira kuchengetwa munzvimbo inotonhorera uye yakaoma kudzivirira zuva rakananga, kuparadzanisa moto uye kuchengetedza kure nekupisa.
(7)Nguva yekuchengetedza ndeye 12 mwedzi. Mushure mekupera, dzakasiyana-siyana dzehunyanzvi indexes dzichaongororwa. Kana vakazadzisa zvinodiwa index, vanogona kuramba kushandiswa.
Fusion bonded epoxy powder, inozivikanwawo se thermosetting epoxy resin heavy-duty anti-corrosion powder, chinhu chakasimba chinotakurwa uye chakaparadzirwa nemhepo semutakuri. Inoshandiswa pamusoro pezvigadzirwa zvesimbi zvinopisa, zvakanyunguduka, zvakaenzana uye zvakasimbiswa kuti zvigadzire yunifomu yejasi. Anti corrosion iheavy-duty anti-corrosion coating inoumbwa pakupisa kwepamusoro. Iyo yekupfekedza ine zvakanakira yeyakapfava yekubata basa, hapana kusvibiswa, yakanaka kukanganisa uye kukotama kuramba uye yakakwirira tembiricha kuramba.
1)Zvinoenderana nemaitiro ekushandisa, inogona kukamurwa kuita: hupfu hwekupfapfaidza mukati mepombi, hupfu hwekupfapfaidza kunze kwepombi uye hupfu huzhinji mukati nekunze kwepombi. Hupfu hunoshandiswa pakupfapfaidza kunze kwepombi inokamurwa kuita imwe-layer powder, double-layer powder uye three-layer structure anti-corrosion powder.
2) Zvinoenderana nechinangwa, inogona kupatsanurwa kuita: pombi yemafuta negasi pombi, pombi yemvura yekunwa, pombi yepombi yemoto, pombi yepombi inorwisa-static ventilation mumugodhi wemarasha, pombi yemakemikari pombi, pombi yepetroleum drill pombi. , hupfu hwepombi fittings, hupfu hwepombi yengarava, hupfu hwemvura ine munyu yakawanda inorema-basa rekudzivirira ngura pombi, nezvimwe.
3)Zvinoenderana nemamiriro ekurapa, inogona kukamurwa kuita marudzi maviri: kukurumidza kurapa uye kurapa kwakajairika. Mamiriro ekurapa ekukurumidza kurapa hupfu kazhinji 230 ℃ / 0.5 ~ 2min. Inonyanya kushandiswa kupfapfaidza kunze kwepombi kana matatu-layer anti-corrosion chimiro. Nekuda kwenguva pfupi yekurapa uye yakakwirira kugadzirwa kwehunyanzvi, inokodzera mutsara wekuita gungano; Mamiriro ekurapa epoda yekurapa yakajairika inowanzopfuura 230 ℃ / 5min. Nekuda kwekurebesa nguva yekurapa uye yakanaka coating leveling, yakakodzera kupfapfaidza mupombi.
Zvikurukuru zvinosanganisira: electrostatic spraying nzira, thermal spraying nzira, kusveta nzira, fluidized mubhedha nzira, roll coating nzira, etc. Friction electrostatic spraying nzira, kusveta nzira kana thermal spraying nzira inowanzoshandiswa pombi mukati rukoko; Iyi nzira dzekupfapfaidza dzine chinhu chakajairika, ndiko kuti, usati wapfapfaidza, iyo workpiece inoda kupiswa kune imwe tembiricha yekunyungudutsa hupfu painongobata. Kupisa kwetsvina kunofanirwa kuita kuti firimu rirambe richiyerera uye kuwedzera nhanho uye kuvhara iyo yese yesimbi pombi pamusoro, kunyanya pakuora kwesimbi pombi pepamusoro uye mativi ese e weld, uye pendi yakanyungudutswa inoyerera ichipinda mukuzadza kugadzira iyo. yakanyatsobatanidzwa nepiipi yesimbi, Deredza pores uye kurapa mukati menguva yakatarwa. Pakupedzisira, tonhorera nemvura kuti umise nzira yekurapa.
