Dziviriro yezvivakwa zvepasi rose: Pendi yeFluorocarbon inodzivirirwa nemvura inodzivirira ngura pamusoro peganda

*Kuumbwa kwechigadzirwa:

Pendi yefluorocarbon inogadzirwa nemvura ipurasitiki inoshanda zvakanaka uye inochengetedza nharaunda inoshandisa resin inogadzirwa nemvura inonzi fluorocarbon sechinhu chikuru chinoita kuti igadzire firimu. Inogara nhaka kugara kwenguva refu, kuramba mamiriro ekunze, uye kuramba ngura kwependi dzechinyakare dzinoshandiswa pakugadzira fluorocarbon, ukuwo kushandisa mvura semusanganiswa kunoderedza zvakanyanya huwandu hweVOC (volatile organic compound), zvichizadzisa dziviriro yezvakatipoteredza yakasvibirira uye zvinodiwa pakugadzira zvakachengeteka. Kubudirira kwekushandiswa kwetekinoroji inogadzirwa nemvura mu fluorocarbon coatings, inorumbidzwa se "mambo we coatings," inomiririra hunyanzvi hwepamusoro muindasitiri yekuvaka nekugadzira madziro ekunze.

*Zvinhu zveChigadzirwa:

● Kuomarara kwakanyanya, kusakara zvakanaka, kusimba kwakanyanya, uye kuramba kukanganiswa.
● Kusapindirana nemamiriro ekunze kwakanyanya uye kuchengetedza ruvara/kupenya: Kunodzivirira zvinobudirira kukanganiswa neUV, kukanganiswa nemvura ine acid, uye kukanganiswa nemhepo nejecha; kunodzivirira kukanganiswa nechoko uye kuchinja ruvara.
● Kudzivirira ngura nemakemikari zvakanyanya: Kudzivirira ngura zvakanyanya kumakemikari mazhinji, zvinonyungudutsa, uye mafuta. Kuvhara kwacho kwakakora kunovhara hunyoro, maion echloride, uye sulfides zvinobudirira, zvichipa dziviriro yakanaka yengura kune concrete nesimbi.
● Inozvichenesa yega uye inodzivirira mavara: Simba shoma pamusoro, zvichiita kuti zvive zvakaoma kuti tsvina inamire.
● Inochengetedza nharaunda uye yakachengeteka: Inonyungudutsa mvura, ine VOC shoma, haina chepfu, haina hwema, haibati moto, uye haiputi, zvichiita kuti ishandiswe zvakanaka.
●Kushanda zvakanaka uye kunamira: Inoratidza kunamira kwakanaka kune zvakasiyana-siyana zve substrates, kusanganisira kongiri yakagadziriswa zvakanaka, simbi, mapaneru ealuminium composite, uye mapendi ekare.

*Ruzivo rwehunyanzvi:

*Kushandiswa Kwechigadzirwa:

Inoshandiswa kudzivirira ngura pamidziyo yemakemikari, mapaipi nenzvimbo dzesimbi munzvimbo dzakaoma dzemaindasitiri. Inogona kupendwa pazvivakwa zvesimbi, mapurojekiti emabhiriji, zvivakwa zvemugungwa, mapuratifomu ekuboorera, madoko nemadhoko, zvivakwa zvesimbi, mainjiniya emaguta, maguardrails anomhanya zvakanyanya, kudzivirira ngura yekongiri, nezvimwewo.

*Kurapa Pamusoro:

Kuti firimu rirambe rakanamira uye rirambe richidzivirirwa kwenguva refu, pamusoro pevhu rinofanira kucheneswa zvakakwana kubva mumafuta, ngura, makwande, pendi yekare, uye tsvina isina kuchena usati waisa. Mitemo yekugadzirira inofanira kusangana nezvinotevera:

Nzvimbo dzese dzinofanira kupendwa dzinofanira kunge dzakachena, dzakaoma uye dzisina kusvibiswa. Nzvimbo dzese dzinofanira kunge dzichienderana neISO dzisati dzapendwa._{8504: 2000}kuongorora nekugadzirisa kwakajairika.

Simbi yakakamurwa yapfurwa kuna Sa_2.5giredhi, kuomarara kwepazasi kuri 30-75μm, kana kuti kwakabikwa muhari, kwakasanganiswa uye kusina kupiswa;

Simbi isina oxide yakaputirwa kuSa_2.5giredhi, kana kuti rakakweshwa kusvika kuSt₃giredhi rine vhiri rekukuya rinokweva mweya kana remagetsi;

Simbi dzakaputirwa nependi yepuraimer yemuworkshop, ngura nengura chena paprimer yeupfu hwezinc zvinofanira kubviswa ngura kaviri, ngura chena inobviswa yokwenenzverwa kusvika St.₃.

Zvimwe zvinhu zvinoshandiswa pakugadzira chigadzirwa ichi, ndapota bvunzai dhipatimendi redu rehunyanzvi.

*Mamiriro Ekuvaka:

Tembiricha yemuchina wepasi haisi pasi pe5 ℃, uye inenge 3 ℃ yakakwira kupfuura tembiricha yemhepo ine dew point uye hunyoro huri <85% (tembiricha nehunyoro hunofanira kuyerwa pedyo nepasi). Kuvaka hakubvumidzwe zvachose kana paine mhute, sinou uye mhepo ine mhepo.

*Matanho Ekuvaka:

Danho 1: Kugadzirira Substrate Pamusoro (TheKiyiDanho)

Hunhu hwekugadzirira pamusoro hunosarudza zvakananga kunamira uye hupenyu hwependi yependi.

Nzvimbo dzesimbi dzinofanira kubviswa mafuta uye dzisina ngura (zvinoenderana nezvinodiwa zveSa2.5 kana St3) kuitira kuti nzvimbo dzesimbi dzinofanira kupendwa dzive dzakachena zvakakwana, dzakaoma zvachose, uye dzisina tsvina dzakadai semafuta, mafuta, guruva, munyu, chikero, uye pendi yekare yakasununguka. Hunyoro hunoonekwa kana kunyorova hazvitenderwi.

Nzvimbo yakarapwa inofanira kusangana nezvinodiwa pakuchena uye kutsvuka kweganda, uye pendi inofanira kuiswa nekukurumidza kudzivirira ngura kudzoka kana kusvibiswa kweganda.

Step2: Isa Primer

Zvichienderana ne substrate nenzvimbo chaiyo, sarudza primer inoenderana (Epoxy Zinc-Rich Primer, Epoxy Zinc Phosphate Primer).

Danho rechitatu: Isa pendi yeFluorocarbon inotorwa nemvura

Dururirai zvishoma nezvishoma chikamu B (chinhu chinogadzirisa) muchikamu A (pendi yefluorocarbon inogadzirwa nemvura), zvakanyatsoenderana nechiyero chakatarwa (nehuremu). Mushure mekukurunga zvizere, regai musanganiswa umire kwemaminitsi mashanu kusvika gumi kuti ukure. Uye jira rakasanganiswa rinoshandiswa mukati memaawa mana (hupenyu hwehari). Wobva wabhurashi/kumonera kana kupfapfaidza, kupfapfaidza kusina mhepo kunobatsira zvikuru uye kunogadzira firimu rependi rakanakisa. Kana uine michina yehunyanzvi uye matekiniki, zvichave zvakanaka. Kushandiswa kwependi yedzidziso ndeye 0.2kg/m²/coat. (Kushandiswa chaiko kunogona kusiyana zvichienderana nekuumbwa kwepamusoro, porosity, nzira yekushandisa uye nzira yekushandisa.)

Cherechedza:

*Kana zvichidikanwa, sanganisa nemvura yakabviswa maion zvichienderana nekuoma kwekushandisa uye nzira (kukwesha, kuzunguza, kana kupfapfaidza). Gadzirisa kuoma kwekushandisa kuti kuenderane nenzira chaiyo yekushandisa.

* Chiyero chekusanganiswa kwemafuta che5-20% nehuremu. Kuonda zvakanyanya kunokanganisa kuvakwa kwefirimu, simba rekuviga, uye kugara kwenguva refu.

* Usati waisa jira rinotevera, iva nechokwadi chekuti jira rekare rapera zvakanaka, rakachena, rakaoma, uye harina tsvina yese.

* Dzivisa kukurunga zvakasimba kudzivirira kupinda kwemabundu akawandisa.

* Nguva Yokuputira Patsva: Munzvimbo dzine ngura zvishoma: pendi imwe chete yeprimer + pendi mbiri dzepakati pejasi + pendi mbiri dzepamusoro pejasi; munzvimbo dzine ngura zvakanyanya, wedzera ukobvu hwependi.

*Nzira yekuvaka:

Kupfapfaidza: Kupfapfaidza pasina mhepo kana kupfapfaidza nemhepo. Kupfapfaidza pasina mhepo ine simba rakawanda kunokurudzirwa.
Kukwesha/Kutenderedza: Ukobvu hwefirimu rakaoma hwakatarwa hunofanira kuwanikwa.

*Sisitimu Yekuputira:

Tinokurudzira kushandisa nzira yakakwana ye "sealing primer + intermediate coat + water-based fluorocarbon topcoat" kuti uwane mhedzisiro yakanaka uye inobudirira pamutengo.

PrimerMienzaniso inosanganisira primer ine mvura yakapfuma mu epoxy zinc uye primer ine mvura yakapfuma mu epoxy. Basa rayo guru nderekudzivirira nekunamatira zvakanaka mukudzivirira ngura.

Jasi repakati:Kazhinji kacho ipurasitiki ye epoxy micaecous iron oxide inobva mumvura. Inowedzera ukobvu hwese hwepurasitiki, inoshanda sechidziviriro kubva kuhunyoro nezvinhu zvinoparadza, uye inowedzera kushanda kwekudzivirira.

Jasi repamusoro:Chifukidziro che fluorocarbon chinopa nzira yekupedzisira yekudzivirira kubva mukuora uye mamiriro ekunze, pamwe chete nechitarisiko chakanaka chaunoda.

*Zvekungwaririra:

▶ Tembiricha yekuvaka ndeye 5℃-35℃ (Kugadziriswa kwakananga kunoitwa zvichienderana nehunhu hwechigadzirwa, hunyoro huri ≤80% uye kudzivirira mvura kunaya.

▶ Chengetedza mhepo yakanaka kuti hunyoro hupfuure uye pendi irambe ichipenya.

▶ Dzivirirai kubva muchando panguva yekuchengetera.

▶ Midziyo yekudzivirira inofanira kupfekwa panguva yekuputira jecha

▶ Mhute, mvura, sinou, mhepo nemvura zvinorambidzwa chose kuvaka.

*Kuchengetera uye Kugara kwenguva refu:

▅ Chengeta munzvimbo inotonhorera, yakaoma, ine mhepo inofefetera mukati memba patembiricha ye5-35 ℃, usaomese uye usanyanya kutonhora nezuva zvakananga;

▅ Hupenyu hwemuviri imwedzi gumi nemiviri. Kana zvigadzirwa zvikadarika nguva yekuchengetera zvinogona kushandiswa mushure mekupasa bvunzo.

*Pakeji:

Pendi：20Kg/Bucket(18Liter/Bucket); Muchina wekusimbisa: 4Kg/Bucket(4Liter/Bucket) kana kuti yakagadzirirwa.
