Pendi yePolyurethane Inodzivirira Kuora yeNyanzvi yeGiredhi reMvura

*Kuumbwa kwechigadzirwa:

Pendi yepolyurethane inodzivirira ngura ine zvikamu zviviri inosanganisira resin inopinzwa mumvura, pigments dzinodzivirira mamiriro ekunze, zvimwe zvinowedzerwa zvakasiyana-siyana, uye mushonga unodzivirira ngura unodzivirira mvura, ine simba rakanaka rekudzivirira ngura uye inochengetedza nharaunda. Chigadzirwa ichi chine VOC shoma, inosangana nezvinodiwa zvemazuva ano zvekuchengetedza nharaunda uku ichipa simba rekudzivirira rakafanana nependi dzechinyakare dzinoshandiswa mukugadzirisa makemikari.

*Zvinhu zveChigadzirwa:

● Kushandisa mvura semusanganiswa wemvura, isinganhuwi, isingasvibisi, isingabati uye isingaputi.

● Kuramba yero, kuramba mamiriro ekunze akanaka, kupenya kwakanaka uye kuchengetedza ruvara.

● Yakajeka uye yakakora zvakanaka.

● Kunamira kwakanaka kwazvo, kuomarara kwakanyanya, kuramba kupfeka kwakanyanya.

● Mvura, mafuta, zvinonyungudutsa uye zvinodzivirira makemikari zvakanaka kwazvo.

● Kudzivirira kupisa nehunyoro zvakanaka uye munyu.

*Kushandiswa Kwechigadzirwa:

Pendi dzepolyurethane dzinoshandiswa mumvura dzinoshandiswa zvakanyanya muma topcoats ekushongedza ekunze ane zvinodiwa zvakanyanya, zvakaita semichina, matangi ekusanganisa, mabhiriji, matangi ekuchengetera zvinhu, magaba, ngarava, uye kunyanya mota. Dzinogona kushandiswawo pakuputira mapurasitiki, dzichipa machira ane ruvara uye anodzivirira zvigadzirwa zvepurasitiki zvakaita semabhokisi ezvigadzirwa zvemagetsi, matoyi, nemidziyo yemumba.

*Ruzivo rwehunyanzvi:

*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.

*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.

*Mamiriro 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.

Danho rechipiri: Shandisa Primer

Kuti uve nechokwadi chekuti ngura haiparadzike zvakanaka, taura nezve primer imwe chete inodzivirira ngura, inogona kunatsiridza kunamira kwayo pa substrate uye ine hunhu hwakanaka hwekudzivirira ngura.

Danho rechitatu: Isa pendi yePolyurethane ine Mvura

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.)

*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 ≤80%.

▶ 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.

*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: 20kg/bhaketi, Hardener/mushonga wekurapa: 4Kg/bhaketi kana kugadzirisa
