Yaing'ono Kakulidwe HDPE/PPR/PE-RT/PA Chitoliro Extrusion Line
Main Technical Parameter
Magwiridwe ＆ Ubwino
servo-controlled high-liwiro lamba wapawiri-lamba wochotsa mbali, wothandizira wodula kwambiri wopanda chipless ndi winder, amatengera magwiridwe antchito othamanga kwambiri.
Wapawiri chitoliro extrusion mzere akhoza kuwirikiza linanena bungwe ndi kukhala zochepa fakitale danga.
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 pa 5% yakunja.
