Pendi yeEpoxy Inoshanda Zvakanyanya Mvura: Pendi Inodzivirira Kuora

*Kuumbwa kwechigadzirwa:

Pendi ye epoxy inogadzirwa nemvura ine zvikamu zviviri, inoshanda zvakanyanya, uye inochengetedza nharaunda, ine epoxy resin yakagadziriswa nemvura, pigments dzinodzivirira ngura, fillers, zvinowedzera uye mvura yakabviswa ion, nezvimwewo. Uye inosanganisa kunamira kwakanaka, kuramba makemikari, uye kuramba ngura kwependi ye epoxy yechinyakare nemabhenefiti akakosha ependi inogadzirwa nemvura, senge kuchengetedzeka kwezvakatipoteredza uye VOC yakaderera zvakanyanya. Isarudzo yakakosha yekushandiswa kwekudzivirira ngura senge ngarava, mabhiriji, uye zvivakwa zvesimbi.

*Zvinhu zveChigadzirwa:

● Kuvhara zvakatipoteredza, kushandisa mvura seyakatetepa, VOC shoma zvakanyanya, kuchengetera nekuvaka kwakachengeteka uye kwakasimba, hakubatidzi moto uye hakuputi.

● Inoshanda zvakanaka kwazvo mukudzivirira ngura uye kudzivirira ngura.

● Kunamatira kwakasimba, kuramba acid nealkali zvakanaka, kuramba solvent, uye kuramba mamiriro ekunze zvakanaka.

● Kusabatwa nemakemikari: Pendi yacho yakakora uye inodzivirira ngura kubva mumvura, munyu, mafuta, mabhesi madiki uye acids.

● Kusachembera kwakasimba kwekugadzira, kusapinda mvura zvakanaka, kuchinjika kwakanaka kwependi, kusapindirana kwakasimba, uye dziviriro yakanaka ye substrate.

*Kushandiswa Kwechigadzirwa:

Yakakodzera kudzivirira ngura kwenguva refu pakati nepakati uye inorema yezvivakwa zvesimbi nemidziyo yemakanika munzvimbo dzine ngura dzine mwero kusvika dzakanyanya, uye inogona zvakare kushandiswa pakugadzirisa. Inoshandiswa zvakanyanya pakudzivirira ngura mumaindasitiri mumabhiriji, zvivakwa zvesimbi zvekuchengetera zvinhu, zvivakwa zvesimbi mumaindasitiri epetrochemical, emagetsi, uye esimbi, mapaipi, matangi ekuchengetera zvinhu (madziro ekunze), zvinotsigira michina, uye mamwe mashandisirwo emaindasitiri. Inoshandiswawo pakudzivirira ngura mumashandisirwo ekufambisa akadai semichina yechiteshi, michina yekuvaka, mota dzemaindasitiri, maroketi, makontena, uye mota dzekutakura zvinhu. Inogona zvakare kushandiswa pakudzivirira ngura yezvivakwa zvemukati senge makamuri einjini yengarava, masuperstructure, uye matangi eballast.

*Kurapa Pamusoro:

Kuti ive nechokwadi chekuti firimu rinonamira uye kuti harina ngura kwenguva refu, pamusoro pevhu panofanira 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.

Nzvimbo yakarapwa inofanira kunge yakachena, yakaoma, isina mafuta, isina guruva, uye inofanira kuiswa pendi mukati memaawa matanhatu mushure mekuputirwa nejecha kudzivirira ngura pamusoro.

*Ruzivo rwehunyanzvi:

Maitiro ekuita: HG/T 4759-2014

*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.

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 kushata, uye pendi inofanira kuiswa nekukurumidza kudzivirira ngura kudzoka kana kusvibiswa kweimwe nzvimbo.

Danho rechipiri: Shandisa Primer

Kuti uve nechokwadi chekuti mushonga wacho unoshanda zvakanaka, kurudzira kuti uise primer imwe chete yekudzivirira ngura, uye inonatsiridza kunamira kwesubstrate.

Danho rechitatu: Isa pendi yeEpoxy inobva mumvura

Mushure mekuvhura bhaketi, kurungai zvakaenzana nemagetsi kusvika ruvara ne viscosity zvafanana, dururirai zvishoma nezvishoma chikamu B (chinhu chinogadzirisa) muchikamu A (pendi), 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 wakwesha/kupuruzira 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. Zvinokurudzirwa kushandisa spray isina mhepo ine simba rakawanda.

Kukwesha/Kumoneredza: Ukobvu hwefirimu rakaoma hwakatarwa hunofanira kuwanikwa.

*Zvekungwaririra:

▶ Tembiricha yekuvaka ndeye 5℃-35℃ (Kugadziriswa kwakananga kunoitwa zvichienderana nehunhu hwechigadzirwa, hunyoro huri ≤85%.

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

▶ Kuenderana kunofanira kusimbiswa kana uchisanganisa nependi ine solvent (kuyedzwa kwenzvimbo diki kunokurudzirwa).

(bvunzo yenzvimbo diki inokurudzirwa).

▶ Dzivirirai kubva muchando panguva yekuchengetera.

▶ Midziyo yekudzivirira inofanira kupfekwa panguva yekuputira jecha

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

*Kuchengetedza uye Kurarama Kwemunhu:

▅ 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: 20 Kg/Bucket; Mushonga wekuporesa: 4Kg/Bucket kana kugadzirisa

Huremu hwakasanganiswa = 5:1
