High-liwiro Mphamvu yopulumutsa Mphamvu ya HDPE Pipe Extrusion Line
Main Technical Parameter
Magwiridwe ＆ Ubwino
Kafukufuku waposachedwa kwambiri wa kampani yathu ndi chitukuko cha mzere wopulumutsa mphamvu wothamanga kwambiri, woyenera kutulutsa chitoliro chothamanga kwambiri cha polyolefin. 35% kupulumutsa mphamvu ndi 1x kuwonjezeka kwa kupanga bwino. Mapangidwe a 38-40 L/D screw ndi mbiya yodyetsera imapangitsa kuti kusungunula kusungunuke ndi kutulutsa pulasitiki kukhala bwino. Ma gearbox okwera kwambiri, amphamvu kwambiri amaonetsetsa kuti zidazo zikugwira ntchito mokhazikika. Maonekedwe a ma extrusion ndi manja a saizi amatengera kapangidwe kapamwamba kwambiri. Tanki yosinthira pafupipafupi ya PLC, thirakitala yoyendetsedwa ndi ma servo, komanso chodulira chochepa kwambiri cha chip chili ndi makina owongolera kulemera kwa mita. Kulemera kwa chitoliro cha extrusion ndikolondola.
Chitoliro cha HDPE ndi chitoliro cha pulasitiki chosinthika chopangidwa ndi thermoplastic high-sensity polyethylene yomwe imagwiritsidwa ntchito kwambiri potengera kutentha kwamadzi komanso kusamutsa mpweya. Posachedwapa, mapaipi a HDPE adagwiritsa ntchito kwambiri kunyamula madzi amchere, zinyalala zowopsa, mpweya wosiyanasiyana, slurry, madzi amoto, madzi amkuntho, ndi zina zambiri. Kulumikizana kolimba kwa ma cell a zida za chitoliro cha HDPE kumawathandiza kuti azigwiritsa ntchito mapaipi othamanga kwambiri. Mapaipi a polyethylene ali ndi mbiri yayitali komanso yodziwika bwino yamagasi, mafuta, migodi, madzi, ndi mafakitale ena. Chifukwa cha kulemera kwake kochepa komanso kukana kwa dzimbiri, makampani opanga mapaipi a HDPE akukula kwambiri. M’chaka cha 1953, Karl Ziegler ndi Erhard Holzkamp anapeza polyethene yochuluka kwambiri (HDPE). Mapaipi a HDPE amatha kugwira ntchito moyenera pa kutentha kwakukulu kwa -2200 F mpaka +1800 F. Komabe, kugwiritsa ntchito Mapaipi a HDPE sikukunenedwa pamene kutentha kwamadzi kumapitirira 1220 F (500 C).
Mapaipi a HDPE amapangidwa ndi polymerization ya ethylene, yopangidwa ndi mafuta. Zowonjezera zosiyanasiyana (ma stabilizer, fillers, plasticizers, softeners, lubricant, colorants, retardants flame, blowing agents, crosslinking agents, ultraviolet degradable additives, etc.) amawonjezeredwa kuti apange chitoliro chomaliza cha HDPE ndi zigawo zake. Kutalika kwa mapaipi a HDPE kumapangidwa ndikuwotcha utomoni wa HDPE. Kenako imatulutsidwa kudzera mu ufa, womwe umatsimikizira kukula kwa payipi. Kuchuluka kwa khoma la Pipe kumatsimikiziridwa ndi kuphatikiza kukula kwa kufa, liwiro la wononga, ndi liwiro la thirakitala yonyamula. Nthawi zambiri, 3-5% yakuda ya kaboni imawonjezeredwa ku HDPE kuti ikhale yosamva UV, yomwe imatembenuza mapaipi a HDPE kukhala akuda. Mitundu ina yamitundu ilipo koma nthawi zambiri sagwiritsidwa ntchito pafupipafupi. Chitoliro cha HDPE chamitundu kapena chamizere nthawi zambiri chimakhala 90-95% yakuda, pomwe mizere yakuda imaperekedwa 5% yakunja.
