Kuponyera thovu lotayika, komwe kumadziwikanso kuti solid mold casting, kumangiriza ndi kuphatikiza mitundu ya thovu yofanana ndi yoponyera m'magulu amitundu.Pambuyo kutsuka ndi penti refractory ndi kuyanika, iwo m'manda youma quartz mchenga chitsanzo kugwedera, ndi kutsanuliridwa ndi kupsyinjika zoipa kuti chitsanzo tsango.Model gasification, zitsulo zamadzimadzi zimagwira ntchito yachitsanzo, zolimba ndi kuzizidwa kuti apange njira yatsopano yoponyera.Njira yonse yoyendera ndi motere:

Choyamba, kusankha mikanda thovu:

Mikanda yowonjezereka ya polystyrene resin (EPS) imagwiritsidwa ntchito nthawi zambiri popanga zitsulo zopanda chitsulo, chitsulo chotuwira komanso chitsulo chambiri.

2. Kupanga zitsanzo: Pali zochitika ziwiri:

1. Wopangidwa kuchokera ku thovu mikanda: pre- thovu - kuchiritsa - kuumba thovu - kuziziritsa ndi ejection

① Pre-foaming: Mikanda ya EPS isanawonjezedwe mu nkhungu, iyenera kukhala ndi thovu kuti iwonjezere mikandayo mpaka kukula kwake.Ndondomeko ya pre-foaming imatsimikizira kuchuluka kwake, kukhazikika kwa mawonekedwe ndi kulondola kwachitsanzocho ndipo ndi chimodzi mwazofunikira kwambiri.Pali njira zitatu zoyenera zopangira mikanda prefoaming: madzi otentha prefoaming, nthunzi prefoaming ndi vacuum prefoaming.Mikanda yokhala ndi thovu isanatulukemo imakhala ndi thovu lalikulu, mikanda youma, ndipo imagwiritsidwa ntchito kwambiri.

②Kukalamba: Mikanda ya EPS yopangidwa kale thovu imayikidwa mu silo youma ndi mpweya wabwino kwa nthawi inayake.Pofuna kulinganiza kuthamanga kwa kunja kwa maselo a mikanda, pangani mikandayo kukhala ndi elasticity ndi kukulitsanso mphamvu, ndikuchotsa madzi pamwamba pa mikanda.Nthawi yokalamba ndi maola 8 mpaka 48.

③Kupanga thovu: Dzazani mikanda ya EPS yopangidwa kale thovu ndi kuchiritsidwa mumtsempha wa nkhungu yachitsulo, ndikuwotcha mikandayo kuti ikulenso, lembani mipata pakati pa mikandayo, ndikuphatikiza mikandayo wina ndi mnzake kuti ikhale yosalala, yofananira. .Iyenera kuziziritsa nkhungu isanatulutsidwe, kotero kuti chitsanzocho chizikhazikika pansi pa kutentha kofewa, ndipo nkhungu ikhoza kumasulidwa pambuyo poti chitsanzocho chaumitsidwa ndikuwumbidwa.Pambuyo pa nkhungu kumasulidwa, payenera kukhala nthawi yoti chitsanzocho chiwume ndi kukhazikika.

2. Wopangidwa ndi pepala la pulasitiki la thovu: pepala la pulasitiki la thovu - kukana waya kudula - kugwirizana - chitsanzo.Kwa zitsanzo zosavuta, kukana waya kudula chipangizo angagwiritsidwe ntchito kudula thovu pulasitiki pepala mu chitsanzo chofunika.Pazitsanzo zovuta, choyamba gwiritsani ntchito chida chodulira waya chotsutsa kuti mugawanitse chitsanzocho m'magawo angapo, ndikumata kuti chikhale chitsanzo chonse.

3. Zitsanzo zimaphatikizidwa m'magulu: chojambula chodzipangira (kapena chogulidwa) cha thovu ndi chitsanzo chokwera chothira zimaphatikizidwa ndi kugwirizana kuti apange gulu lachitsanzo.Kuphatikiza uku kumachitika nthawi zina pamaso pa zokutira, nthawi zina pokonzekera zokutira.Imachitidwa panthawi yoyika bokosi lachitsanzo.Ndi njira yofunikira pakuponya chithovu (cholimba) chotayika.Zomangira zomwe zimagwiritsidwa ntchito pano: labala labala, zosungunulira za utomoni ndi zomatira zotentha zosungunuka ndi tepi pepala.

4. Kuphimba kwachitsanzo: Pamwamba pa chitsanzo cholimba choponyera chithovu chiyenera kuphimbidwa ndi utoto wochuluka kuti apange chipolopolo chamkati cha nkhungu yoponyera.Kwa utoto wapadera woponyera thovu wotayika, onjezerani madzi ndikugwedeza mu chosakaniza utoto kuti mupeze mamasukidwe oyenera.Utoto wotenthedwa umayikidwa mu chidebe, ndipo gulu lachitsanzo limakutidwa ndi njira zoviika, kupaka, kusamba ndi kupopera mbewu mankhwalawa.Nthawi zambiri, ntchito kawiri kuti ❖ kuyanika makulidwe 0,5 ~ 2mm.Zimasankhidwa molingana ndi mtundu wa aloyi woponyera, mawonekedwe apangidwe ndi kukula kwake.Chophimbacho chimauma pa 40 ~ 50 ℃.

5. Kujambula kwa vibration: ndondomekoyi ikuphatikizapo njira zotsatirazi: kukonzekera bedi la mchenga - kuyika chitsanzo cha EPS - kudzaza mchenga - kusindikiza ndi kupanga.

① Kukonzekera kwa bedi la mchenga: Ikani bokosi lamchenga lokhala ndi chipinda chotulutsira mpweya patebulo logwedezeka ndikulilimbitsa mwamphamvu.

②Ikani chitsanzo: Mukagwedezeka, ikani gulu lachitsanzo la EPS pa izo molingana ndi zofunikira za ndondomekoyi, ndikukonza ndi mchenga.

③ Kudzaza mchenga: onjezani mchenga wouma (njira zingapo zowonjezera mchenga), ndipo nthawi yomweyo gwiritsani ntchito kugwedezeka (X, Y, Z mayendedwe atatu), nthawiyo imakhala masekondi 30 ~ 60, kuti mchenga wowuma udzadzazidwa ndi magawo onse. wa chitsanzo, ndi mchenga wodzazidwa ndi mchenga.Kuchulukana kwakukulu kumawonjezeka.

④Chisindikizo ndi mawonekedwe: Pamwamba pa bokosi la mchenga losindikizidwa ndi filimu ya pulasitiki, mkati mwa bokosi la mchenga limaponyedwa muzitsulo zina ndi pampu ya vacuum, ndipo njere za mchenga "zimamangirizidwa" palimodzi ndi kusiyana pakati pa kuthamanga kwa mlengalenga ndi mpweya. kuthamanga mu nkhungu, kuti nkhungu zisagwe pa nthawi yothira., yotchedwa "negative pressure setting, yomwe imagwiritsidwa ntchito kwambiri.

6. Kuthira m'malo: Mtunduwu nthawi zambiri umafewetsedwa pafupifupi 80 °C, ndikuwola pa 420 ~ 480 °C.Zopangira zowonongeka zili ndi magawo atatu: gasi, madzi ndi olimba.Kutentha kwa kutentha kwa kutentha kumasiyana, ndipo zomwe zili mu zitatuzi ndizosiyana.Pamene nkhungu yolimba imatsanuliridwa, pansi pa kutentha kwa zitsulo zamadzimadzi, chitsanzo cha EPS chimadutsa pyrolysis ndi gasification, ndipo mpweya wambiri umapangidwa, womwe umatulutsidwa mosalekeza kudzera mumchenga wokutira ndi kutulutsidwa kunja, kupanga mpweya wina. kuthamanga mu nkhungu, chitsanzo ndi kusiyana kwachitsulo.Chitsulo mosalekeza chimatenga udindo wa chitsanzo cha EPS ndikupita patsogolo, ndipo m'malo mwake zitsulo zamadzimadzi ndi chitsanzo cha EPS zimachitika.Chotsatira chomaliza cha kusamuka ndiko kupanga kuponyera.

7. Kuziziritsa ndi kuyeretsa: Mukazizira, ndikosavuta kuponya mchenga pamalo olimba.Ndizotheka kupendekera bokosi la mchenga kuti mutulutse kuponyedwa m'bokosi la mchenga kapena kukweza mwachindunji kuponya kuchokera mubokosi la mchenga, ndipo mchenga wowuma ndi wowuma umasiyanitsidwa mwachilengedwe.Mchenga wowuma wolekanitsidwa umagwiritsidwa ntchito ndikugwiritsidwanso ntchito.
