Anthu omwe amagwiritsa ntchito nthawi zambiriPE payipizomangamanga mukudziwa zimenezoPE payipipamwamba ili ndi mizere yofanana ndi mtundu womwewo, buluu, chikasu, wofiira, ndiye zikutanthauza chiyani?Pamsika wamapaipi aku China, chitoliro chamadzi ndi chitoliro cha gasi ndi misika iwiri yayikulu yogwiritsira ntchito.PE mankhwala Chinese dzina, polyethylene, PE zinthu chifukwa cha mphamvu zake mkulu, kutentha kukana, dzimbiri kukana, sanali poizoni, kuvala kukana ndi makhalidwe ena, chimagwiritsidwa ntchito m'munda wa madzi ndi ngalande kupanga.Chifukwa sichichita dzimbiri, kotero ndi chitoliro chabwino chosinthira chitoliro wamba chachitsulo;Malinga ndi kugwiritsidwa ntchito kwake, pamwamba pa chubu cha PE amasiyanitsidwa ndi mizere yolembera mitundu yosiyanasiyana.Mitundu yotsatirayi imayimira ntchito zingapo motsatana:
1.Mzere wa chizindikiro chofiyira: Chitoliro cha mgodi wa PE
Mwa mapulasitiki onse aumisiri, kukana kwa HDPE kumakhala kolona wa mapulasitiki, okopa maso.Kulemera kwa mamolekyu azinthu, kumapangitsa kuti zisawonongeke kwambiri, ngakhale kuposa zipangizo zambiri zazitsulo (monga carbon steel, chitsulo chosapanga dzimbiri, bronze, etc.).Pokhala ndi dzimbiri lamphamvu komanso kuvala kwakukulu, moyo wake wautumiki ndi 4-6 nthawi ya chitoliro chachitsulo ndi 9 nthawi ya polyethylene wamba.Ndipo onjezerani mphamvu zotumizira ndi 20%.
Flame retardant, antistatic performance ndiyabwino, zonse zimakwaniritsa zofunikira.Moyo wautumiki wa Downhole wazaka zopitilira 20, zopindulitsa zachuma, kukana kwamphamvu, kukana kuvala, kukana kawiri.
2.Mzere wabuluu:Chitoliro chamadzi cha PE, chitoliro, ndi chitoliro cha moto
PE blowdown pipe: Chitoliro cha PE chomwe chimagwiritsidwa ntchito potsitsa chimatchedwanso chitoliro chapamwamba cha polyethylene, chomwe ndi HDPE mu Chingerezi.Chitoliro chamtunduwu nthawi zambiri chimagwiritsidwa ntchito ngati chitoliro chaumisiri wamatauni, chomwe chimagwiritsidwa ntchito makamaka mu: mafakitale ochizira zimbudzi.Chifukwa cha kukana kwake kuvala, kukana kwa asidi, kukana kwa dzimbiri, kukana kutentha kwakukulu, kukana kuthamanga kwambiri ndi makhalidwe ena, pang'onopang'ono m'malo mwa chitoliro chachitsulo, chitoliro cha simenti ndi mapaipi ena pamsika, makamaka chifukwa chitolirocho chimakhala chopepuka. kulemera ndi kosavuta kukhazikitsa ndi kusuntha, ndiye chisankho chabwino kwambiri cha zipangizo zatsopano.
PE madzi chitoliro: PE chitoliro kwa madzi ndi mankhwala m'malo mwa miyambo zitsulo chitoliro ndi PVC madzi akumwa chitoliro.Chitoliro chamadzi chiyenera kukhala ndi kukakamizidwa kwina, kawirikawiri kusankha kulemera kwakukulu kwa maselo, makina abwino a PE resin, monga HDPE resin.Utoto wa LDPE uli ndi mphamvu zotsika kwambiri, kukana kupanikizika, kusakhazikika bwino, kukhazikika kwapang'onopang'ono popanga ndi kukonza, komanso kulumikizana kovuta, sikoyenera ngati chitoliro chamadzi.Komabe, chifukwa cha index yake yathanzi, PE, makamaka HDPE resin, yakhala chinthu chodziwika bwino popanga mapaipi amadzi akumwa.Utomoni wa HDPE uli ndi viscosity yaying'ono yosungunuka, madzi abwino komanso osavuta kukonza, kotero kuti masanjidwe ake osungunuka amakhalanso otakasuka, nthawi zambiri MI pakati pa 0.3-3g / 10min.
3.Yellow label line: PE gasi chitoliro
PE chitoliro kwa mpweya ndi mankhwala m'malo chikhalidwe zitsulo chitoliro ndi PVC mpweya.
Gasi chitoliro ayenera kukhala ndi mavuto, kawirikawiri kusankha mkulu maselo kulemera, zabwino makina zimatha Pe utomoni, monga HDPE utomoni.Utoto wa HDPE umakhala ndi mphamvu zotsika kwambiri, kukana kupanikizika, kusakhazikika bwino, kusasunthika kwapang'onopang'ono popanga, komanso kulumikizana kovuta, sikoyenera ngati chitoliro chamadzi.Komabe, LDPE, makamaka utomoni wa LLDPE, wakhala chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga chitoliro cha gasi chifukwa chokhala ndi thanzi labwino.LDPE, LLDPE resin melt viscosity ndi yaying'ono, fluidity yabwino, yosavuta kukonza, kotero masankhidwe ake osungunuka amasungunuka ndi ambiri, kawirikawiri MI pakati pa 0.3-3g / 10min.
