Pendi inodzivirira ngura

Pendi inodzivirira ngura rudzi rwechinhu chinoita basa rekudzivirira ngura, inodzivirira ngura yesimbi uye inovandudza simba rekudzivirira rependi pamusoro pesimbi. Basa rependi inodzivirira ngura rinogona kukamurwa muzvikamu zviviri: inodzivirira ngura chaiyo uye inodzivirira ngura yemakemikari, iyo pendi inodzivirira ngura yemakemikari inogona kukamurwa muzvikamu zviviri: kudzivirira ngura uye electrochemical action type two. Zvinhu zvinoita basa rekudzivirira ngura zvinosanganisira hupfu hwepingi dzvuku, hupfu hwesimbi tsvuku, hupfu hwetitanium yesimbi yakabatanidzwa, hupfu hwealuminium tripolyphosphate zinc nezvimwewo. Parizvino, pendi inodzivirira ngura inonyanya kushandiswa mukudzivirira ngura, uye mutengo wezvinodzivirira ngura unokwana 6%-8.5%.

Ndeupi musiyano uripo pakati pependi inorwisa ngura nependi?

Pendi yekudzivirira ngura imhando yependi inogona kudzivirira pamusoro pesimbi kubva mukuora kwemhepo, mvura yegungwa, nezvimwewo. Pendi yepanyama uye yemakemikari inodzivirira ngura, senge iron red, aruminiyamu powder, graphite anti-ngura pendi, red lead, zinc yellow anti-ngura pendi nezvimwewo.

Pendi ipurasitiki inosanganiswa nemakemikari inofukidza zvakasimba pamusoro pezvinhu, inodzivirira, inoshongedza, inoisa mamakisi nezvimwe zvinangwa zvakakosha, uye inoumba firimu rakasimba rinonamira zvakasimba pamusoro pezvinhu uye rine simba rakati uye rinoenderera mberi.

1. Mabasa akasiyana:

Pendi inodzivirira ngura ine hunhu hwekudzivirira ngura uye kudzivirira ngura, firimu racho rakasimba, rinoita zvakanaka, uye kuoma kwaro kwakanyanya kupfuura kwependi yakajairika. Pendi yakajairika haina basa rekudzivirira ngura, nekuti pendi yakajairika ine alkyd resin, kuburikidza ne oxidation nekuomesa, kuomarara kwakaderera, uye gap yegiredhi rekunamatira.

2. Hupenyu hwebasa hwakasiyana:

Pendi inodzivirira ngura inogona kushandiswa kwemakore mashanu kusvika masere kana yakaenzana. Pendi yakajairika inowanzo shandiswa panze kwemakore angangoita matatu. Mushure memakore maviri kana matatu, zviri nyore kudonha, kupera simba uye kuita upfu.

3. Mhando dzakasiyana:

Pendi inodzivirira ngura: pendi inodzivirira ngura ine phenolic, pendi inodzivirira ngura ine alkyd (tsvuku yesimbi, grey, tsvuku), pendi inodzivirira ngura ine chlorinated raber, pendi inodzivirira ngura ine epoxy (pendi inodzivirira ngura ine zinc phosphate, pendi inodzivirira ngura ine lead tsvuku, pendi inodzivirira ngura ine zinc yakawanda, pendi inodzivirira ngura ine iron tsvuku), nezvimwewo.

Pendi: Mhando dzakasiyana dzependi, pendi inodzivirira ngura imhando yependi, pamusoro pependi inosanganisirawo pendi yehuni, pendi yepasi, pendi yemadziro ekunze, pendi yematombo, pendi ine mavara akawanda, pendi yearuminiyamu alloy, pendi isingatsvi, pendi yelatex nezvimwewo.

Nzira sere dzekuvandudza pendi inodzivirira ngura mune ramangwana

Chekutanga, kugadzirwa kweprimer inodzivirira ngura inobva mumvura uye pendi yepamusoro yezvivakwa zvesimbi.

Primer inodzivirira ngura inobva mumvura inofanira kugadzirisa dambudziko re "flash rust" ye substrate uye kusagadzikana kwemvura, uye kukwira kwemamwe emulsifier matsva asina emulsifier kwakavandudza zvakanyanya zita rayo rekudzivirira mvura, uye ramangwana rinofanira kutarisa pakugadzirisa matambudziko ebasa rekuvaka uye basa rekushandisa. Se topcoat, inonyanya kukosha pakuvandudza kushongedzwa kwayo uye kugara kwenguva refu pasi pemamiriro ekuona kuti basa rekudzivirira riripo.

Chechipiri ndechekugadzira pendi ine zvinhu zvakawanda zvakasimba uye inodzivirira ngura isina zvinonyungudutsa.

Kuchera, mapuratifomu ekunze kwenyika uye mapurojekiti makuru ekudzivirira ngura mumabasa ekudzivirira ngura akasimba kwazvo ezvinodiwa zvekuputira zvinokurumidza zvikuru, musika uripo unongori makambani ekunze uye zvigadzirwa zvinobva kunze kwenyika. Zvigadzirwa zveChina zvinonyanya kuve muchikamu chehunyanzvi, simba rehupfumi, sisitimu yekuvimbisa mhando uye mukurumbira wechigadzirwa uye imwe musiyano wakazara wesimba nenyika dzekunze, zvakaoma kupinda mumusika. Kuti izvi zviitike, kutanga, kuedza kunofanirwa kuitwa mukuvandudza tekinoroji, kunyanya kusimudzira primer isina lead uye isina chromium anti-ngura, kureva kuti, yakavakirwa pazinc phosphate uye aluminium tripolyphosphate anti-ngura primer.

Chechitatu ndechekugadzira primer ine zinc yakawanda mumvura.

Mapurimita asina kusimba ane zinc yakawanda uye mapurimita asina kusimba ane zinc yakawanda anowanikwa mumvura ndeimwe yemapurimita anoshanda kwenguva refu, asi iwo mapurimita anonyungudika. Mapurimita asina kusimba ane zinc yakawanda anowanikwa mumvura ane modulus potassium silicate yakawanda sehwaro hwezvinhu ipurimita inoshanda zvakanyanya inodzivirira ngura yakaedzwa nemaitiro uye ine mukana wekukura.

Chechina ndechekugadzira chinodzivirira ngura chinodzivirira kupisa chinogadzirisa kupisa.

Zvinochinja-chinja kupisa zvinoda machira anodzivirira ngura ane simba rekudzivirira kupisa uye kufambisa kupisa, uye epoxy amino coating iri kushandiswa parizvino inoda kugadziriswa pa120 ° C uye inoda machira akawanda, ayo asingakwanise kushandiswa pamidziyo mikuru.

Chechishanu kugadzira chifukidziro chinogona kurapwa kana tembiricha yemumba uye chiri nyore kuisa.

Chinhu chikuru ndechekuwana chiyero chakanakisa pakati pebasa rekudzivirira ngura, basa rekutamisa kupisa uye basa rekuvaka rependi.

Chechitanhatu ndechekugadzirwa kwepurasitiki inodzivirira ngura.

Mica iron oxide (MIO) ine simba guru rekudzivirira kupisa, inodzivirira kukwegura uye inovhara ganda, uye inoshandiswa zvakanyanya sependi yekutanga uye yepamusoro muWestern Europe.

Chechinomwe, kugadzirwa kwemhando yerabha ine chlorine inotsiva ngura.

Nekuti rabha ine chlorine chinhu chimwe chete, kugadzirwa kwayo kuri nyore, kudzivirira mvura, kudzivirira mafuta, kudzivirira kukwegura kwemhepo kwakanaka kwazvo, kunoshandiswa zvakanyanya mukuvaka ngarava, kudzivirira ngura mumaindasitiri nedzimwe nzvimbo, kune musika wakakura muChina. Zvisinei, nekuti kugadzirwa kwerabha ine chlorine kunoshandisa CC1 semushonga unonyungudutsa, ozone layer inoparadzwa.

Chechisere ndechekugadzirwa kwezvinhu zvinodzivirira ngura zvisingasanganisirwe nemakemikari.

Mumakore achangopfuura, kushandiswa kwekongiri yakachinjwa ye organic emulsion kuti ivandudze simba rayo, ine simba repakati nepakati, inoshandiswa zvakanyanya mukugadzira pasi pemaindasitiri. Pakati pavo, epoxy water emulsion (kana epoxy-based solvent) iri kugadzira inokurumidza kupfuura dzose, inonzi polymer simende.

Nezvedu

Kambani yeduYagara ichitevedzera "sainzi netekinoroji, mhando yekutanga, yakatendeseka uye yakavimbika, uye yakanyatsogadziriswa kwe ls0900l:.2000 system yepasi rose yekutarisira mhando. Kutungamira kwedu kwakasimba tekinoroji itsva, sevhisi yepamusoro, yakawana kuzivikanwa kwevashandisi vazhinji.Senyanzvi, fekitori yeChinese yakasimba uye yakajairika, tinogona kupa mienzaniso kune vatengi vanoda kutenga, kana muchida pendi inodzivirira ngura, ndapota taurai nesu.
