Cast iron pombi epoxy resin inodiwa kusvika maawa 350 emunyu wekupfapfaidza bvunzo pasi pe EN877 standard, kunyanya.DS sml pombi inogona kusvika maawa 1500 emunyu wekupfapfaidzatest(yakawana Hong Kong CASTCO certification muna 2025). Yakakurudzirwa kushandiswa munzvimbo dzine hunyoro uye kunaya, kunyanya pamhenderekedzo yegungwa, iyo epoxy resin coating pane yekunze nhovo yeDS SML pombi inopa chengetedzo yakanaka yepombi. Nekuwedzera kwekushandiswa kwemakemikari emumba senge organic acids uye caustic soda, epoxy coating ndiyo yakanakisa chipingamupinyi kurwisa zvinhu zvinopinda, ukuwo kugadzira mapaipi akatsetseka kudzivirira tsvina kuvhara. Iyo anti-corrosion midziyo yemapombi esimbi yakakandwa inoita kuti ishandiswe zvakanyanya mumarabhoritari, zvipatara, mafekitori nedzimba dzekugara pasirese.
Nekudaro, kana pendi isina kuchengetwa zvakanaka, inogona kuita kuti pombi yesimbi ive yakareruka kana kutsvuka mushure mekupenda, zvichikanganisa kutaridzika kwemhando uye kuchengetedza kwechigadzirwa.
1. Nzira yakarurama yekuchengetedza yeA1 epoxy pendi
A1 epoxy pendi ndeyepamusoro-inoshanda inodzivirira yekudzivirira, uye mamiriro ayo ekuchengetedza anokanganisa zvakananga kugadzikana kweiyo coating uye coating effect. Iyo chaiyo yekuchengetedza nzira inosanganisira zvinotevera zvinhu:
1. Kudzora tembiricha
Tembiricha yakakodzera: A1 epoxy pendi inofanirwa kuchengetwa munzvimbo ye5 ℃ ~ 30 ℃ kudzivirira yakakwira kana yakaderera tembiricha inokanganisa kugadzikana kwekemikari yepende.
Dzivisa tembiricha yakanyanyisa:Tembiricha yepamusoro (> 35 ℃) ichaita kuti chinonyungudutsa chiri mupende chinyunguduke nekukasira, uye chikamu cheresin chinogona kuita polymerization reaction, izvo zvinozowedzera viscosity yepende kana kutokonzeresa kutadza kurapa.
Kudzikira tembiricha (<0 ℃) inogona kukonzera kuti zvimwe zvikamu mupende zvipenye kana kupatsanurwa, zvichikonzera kudzikira kwekunamatira kana kusaenzana kweruvara mushure mekupenda.
2. Humidity management
Nzvimbo yakaoma: Hunyoro hwenzvimbo yekuchengetera hunofanirwa kudzorwa pakati pe50% ne70% kudzivirira mweya wakanyorova kuti usapinde mubhaketi repende.
Yakavharwa uye hunyoro-uchapupu: Bhakiti repende rinofanirwa kunyatsovharwa kudzivirira hunyoro kubva mukati, zvikasadaro zvinogona kukonzera pendi stratification, agglomeration kana kupora zvisina kujairika.
3. Kuchengetedza kure nechiedza
Dzivisa zuva rakananga: Mwaranzi yeUltraviolet inomhanyisa kuchembera kwe epoxy resin, zvichikonzera shanduko yeruvara rwependi kana kuderera kwekuita. Nokudaro, pendi yacho inofanira kuchengetwa munzvimbo inotonhorera, isina chiedza.
Shandisa midziyo yakasviba: Mamwe maA1 epoxy pendi akaiswa mukati memavara akasviba kuti aderedze photosensitivity. Iyo yekutanga kurongedza inofanira kuchengetwa yakasimba panguva yekuchengetedza.
4. Dzivisa kumira kwenguva refu
Shandura nguva dzose: Kana pende yakachengetwa kwenguva yakareba (inopfuura mwedzi mitanhatu), bhakiti repende rinofanira kushandurwa kana kupetwa nguva dzose kudzivirira pigment uye resin kubva pakugadzirisa uye kugadzikana.
Chekutanga-mu-yekutanga-kunze musimboti: Shandisa mukurongeka kwezuva rekugadzira kudzivirira kutadza kwependi nekuda kwekupera.
5. Gara kure nekusvibiswa kwemakemikari
Chengetedza zvakasiyana: Pendi inofanira kuchengetedzwa kure nemakemikari akaita seasidhi, alkalis, uye organic solvents kudzivirira kemikari inokonzera kukanganisa.
Kufefetedza kwakanaka: Nzvimbo yekuchengetera inofanirwa kufefeterwa kudzivirira kuunganidzwa kwezvinhu zvinoputika zvinokanganisa kunaka kwepende.

2. Ongororo yezvikonzero zvekukanda simbi pombi ruvara kupenya kana kubuda
Kana A1 epoxy pendi isina kuchengetwa zvakanaka, pombi yesimbi yakakandwa mushure mekupenda inogona kunge iine matambudziko senge kupenya, kutsvuka, kuchena, kana kudzima zvishoma. Zvikonzero zvikuru zvinosanganisira:
1. Kupisa kwepamusoro kunokonzera kukwegura kwe resin
Phenomenon: Rudzi rwepende runoshanduka yero kana kusviba mushure mekupenda.
Chikonzero: Pasi pemamiriro ekushisa kwepamusoro, epoxy resin inogona kuokisisa kana kuyambuka-link, zvichiita kuti ruvara rwependi ichinje. Mushure mekupenda, pendi iri pamusoro pepombi yesimbi yakakandwa inogona kurasikirwa nemuvara wayo wepakutanga nekuda kwekuchembera kweresin.
2. Kupindira kwehunyoro kunotungamirira kukurapa kusina kujairika
Phenomenon: White mhute, kuchena kana ruvara rusina kuenzana rwunoonekwa pamusoro pejasi.
Chikonzero: Iyo pendi yependi haina kuvharwa zvakasimba panguva yekuchengetedza. Mushure mekunge mwando wapinda, inopindirana neanorapa kuti ibudise amine munyu kana kabhoni dhaibhoni, zvichikonzera kukanganisa kwemhute pamusoro pekuputira, zvichikanganisa kupenya kwesimbi yepombi yesimbi yakakandwa.
3. Photodegradation inokonzerwa nemirairo ye ultraviolet
Phenomenon: Muvara wepende unova wakareruka kana musiyano wemuvara unoitika.
Chikonzero: Mwaranzi yeultraviolet muzuva inoparadza pigment uye resin chimiro mupende, zvichiita kuti ruvara rwepamusoro pepombi yesimbi yakakandwa mushure mekupenda kuti ipere zvishoma nezvishoma kana kudzima.
4. Solvent volatilization kana kusvibiswa
Phenomenon: Particles, shrinkage maburi kana discoloration inoonekwa pafirimu repende.
Chikonzero: Yakawandisa solvent volatilization inoita kuti pendi viscosity iwedzere, uye kushomeka kweatomu panguva yekupfapfaidza kunotungamira kune isina kuenzana ruvara.
Zvisina kuchena (zvakadai seguruva nemafuta) zvakasanganiswa panguva yekuchengetedza zvichakanganisa maitiro ekugadzira mafirimu epende uye zvinokonzera kukanganisa pamusoro pepombi yesimbi yakakandwa.
3. Nzira yekudzivirira sei isina kujairika ruvara rwesimbi yakakandwa pombi mushure mekupenda
Nyatsotevedzera mamiriro ekuchengetedza uye simbisa zvinodiwa zvekushisa, humidity, light protection, etc.Kuchengetedzwa kwakashata kwepombi yesimbi yakakandwa neA1 epoxy pendi inogona kuita kuti ruvara ruve rureruke, ruyero kana kusandura. Nekunyatso kudzora tembiricha, humidity, chiedza chekudzivirira uye mamwe mamiriro, uye kugara uchitarisa iyo pt mamiriro, kukanganisa kwekuvhara kunokonzerwa nezvinetso zvekuchengetedza kunogona kudzivirirwa zvinobudirira, kuve nechokwadi chekuti aesthetics uye mashandiro ekudzivirira epombi yesimbi yakakandwa iri mune yakanakisa mamiriro.
