Abstract: Iyo yekumaka yehupamhi yemuchina wekumaka yemanyorero inotarwa nehupamhi hwehopper, inowanzoshandiswa se100mm, 150mm, uye 200mm.Kupisa kunonyunguduka kunoda kudziya kusvika pakati pe180-230 madhigirii celsius isati yaiswa

Nzira dzekumaka kuvaka dzinogona kukamurwa kuita manyorero ekumaka nzira uye mekiniki yekuvaka nzira zvichienderana nemhedzisiro yemuchina wekumaka.Manual marking parizvino ndiyo nzira huru uye inowanzoshandiswa yekuvaka yekupisa-yakanyungudika yekumaka kuvaka.Iyo yekumaka yehupamhi yemuchina wekumaka yemanyorero inotarwa nehupamhi hwehopi, inowanzoshandiswa se100mm, 150mm, uye 200mm.Iyo inopisa melt coating inoda kudziyiswa kusvika pakati pe180-230 degrees Celsius isati yavakwa.Nheyo yekushanda yemuchina wekuisa chiratidzo ndeye kushandisa nzira yekukwenya yekuvaka.Panguva yekuvaka, chivharo chakasimba senge chifukidziro chinoiswa muketani inopisa inonyunguduka, yakanyungudutswa kuita inoyerera, yozoiswa muhumburumbira hwezvinhu zvekuisa muchina wekumaka muchina.Paunenge uchimaka, pendi yakanyungudutswa inounzwa mubhaketi rekumaka, iro rinoiswa zvakananga pamugwagwa.Nekuda kweimwe mukaha pakati pekumaka nepasi, kana muchina wekumaka uchisundirwa, mutsara wekumaka unokwenenzverwa kunze nekuyerera kwe otomatiki.Paunenge uchikwenya kunze mamaki, muchina wemakakina unowaridza dhizaini yegirazi bhero pamusoro pezvibodzwa zvakaenzana.

1. Kubatsira kweruoko urwu rwakasundidzira mugwagwa wepamhepo inopisa melt yekumaka muchina ndeyekuti ine michina yekuvakisa mishoma, hupenyu hurefu hwebasa, uye inogona kushandiswa kwemakore 3-5.Iwo mamaki akagadzirwa ane zvirinani anoratidza maitiro, akasimba anti kusvibiswa kugona, anogona kuramba akajeka kwenguva yakareba, adhesion yakanaka, yakanakisa kupfeka kuramba, uye kusimba.Kuvakwa kwejira rinopisa rinonyunguduka kunofanira kugadzirirwa pachine nguva, zvakadai sembiru dzenyevero, maturusi ebetsero, zviratidzo zvokunyevera zvokuvaka, pamwe chete nemapuranga anodhirowewa anodiwa, maumbirwo emavara, zvichingodaro. Kuchenesa mugwagwa: Kutanga, ita kurapa kunokosha pamusoro penzira. uye bvisa marara mumugwagwa.Kana zvakaoma kubvisa marara mumugwagwa uchishandisa nzira dzakajairwa, simbi yebhurashi yemhando yemugwagwa yekuchenesa muchina inofanira kushandiswa kubviswa kwakaoma, uye ipapo mhepo yemagetsi yekuchenesa nzira inofanirwa kushandiswa kupeperetsa marara munzira yekusangana. mipimo yekuchenesa mugwagwa inodiwa nezviratidzo.

2. Kugadziriswa kwekuvaka: Mukati mechikamu chechikamu chekuvaka, kuyera uye kurongedzerwa zvinoenderana nemifananidzo yekuvaka uye zvinodiwa zvehunyanzvi, kuitira kufambisa kutonga kwemaitiro ekuvaka.Pashure pokunge wapedza kurongwa, ita nzvero yokutanga.Mushure mekupfuura kuongorora kwekutanga, ndapota bvunza injinjiniya anotarisira kuti agamuchirwe.Chete mushure mekupasa kugamuchirwa ndiko kunotevera maitiro kuenderera.Chengetedzo yekugadzira chiratidzo chemumugwagwa: Panguva yekuvaka, shandisa mhepo ine simba-yakanyanya kuchenesa mhepo kupeperetsa marara senge ivhu nejecha riri pamusoro pemugwagwa, kuve nechokwadi chekuti mugwagwa hauna zvidimbu zvakasununguka, huruva, asphalt, mavara emafuta, nezvimwe. tsvina inokanganisa kunaka kwekumaka uye yakaoma.

3. Zvadaro, maererano nezvinodiwa zvekugadzirwa kweinjiniya, muchina wekubhadhara-otomatiki uye kushandiswa kwemaoko kuchashandiswa kubhadhara pane chikamu chekuvaka chinorongwa.Zvino, zvinoenderana nezvinodiwa, muchina wekupfapfaidza usina mhepo usina mhepo wepamusoro uchashandiswa kupfapfaidza mhando imwechete uye dosi reiyo undercoating agent (primer) sekubvumidzwa kwainoitwa nainjiniya anotarisira.Mushure mekunge muchina wekuputira wanyatsoomeswa, kucherekedza kuchaitwa uchishandisa muchina unozvifambisa kana kuti wakabatwa neruoko unopisa unonyungudika.
