Monga ethylene homopolymer yodzaza kwathunthu,PE serandi mzere komanso crystalline.Ichi ndichifukwa chake nkhaniyi itha kugwiritsidwa ntchito ngati zosakaniza, zowonjezera zapulasitiki ndi kupanga mphira.Chifukwa cha crystallinity yake yapamwamba, nkhaniyi ili ndi makhalidwe apadera, monga kuuma pa kutentha kwakukulu ndi kusungunuka kochepa muzitsulo zosiyanasiyana.

Izi ndi thermoplastic, kotero mutha kulingalira momwe zimakhalira mukatenthedwa.Thermoplastics imasungunuka pa 110 ° C. Chinthu chochititsa chidwi cha zipangizozi ndi kuthekera kwawo kutentha ndi kuzizira popanda kuwonongeka kwakukulu.
Polyethylene serailinso ndi poligoni yochepa ndi kulemera kwa maselo.Choncho, zinthuzo zimagonjetsedwa kwambiri ndi mankhwala osokoneza bongo, zimakhala ndi kukhazikika kwa kutentha kosayerekezeka, ndipo zimasinthasintha kwambiri pokonzekera ndi kugwiritsa ntchito.
Kodi mungadziwe bwanji sera ya PE?
Sera ya polyethylene ikhoza kukhala yotsika kachulukidwe polyethylene (LDPE) kapena kachulukidwe kwambiri.Kawirikawiri, HDPE imakonda kukhala wandiweyani komanso wonyezimira, kotero ngati muli ndi njira yodziwira zinthuzi, mutha kuzisiyanitsa.
(1) Tingagwiritse ntchito njira zosiyanasiyana kuti tizindikire sera ya PE kuchokera ku zipangizo zina;Masomphenya, kukhudza, kununkhiza, ndi zina zotero. Sera iyi ndi yofanana ndi pepala lapulasitiki.Ili ndi malo owala.Ngati chinthucho chadulidwa, palibe chodetsedwa kapena kupatukana kulikonse.
(2) Zinthuzo zimakhala ndi mafuta ndipo zimamveka pogwira.Kutentha kwachipinda, sera ya PE ndi yofooka komanso yolimba.
(3) Ngati mukufuna kuyesa nkhaniyo, ganizirani kuiwiritsa m’madzi kwa mphindi zisanu.Maonekedwe a sera enieni a PE sanasinthe.Ngati sera ili ndi parafini kapena zonyansa zilizonse, mudzaphunzira za izo posintha mawonekedwe ake.

Kugwiritsa ntchito phula
Chifukwa cha mawonekedwe ake abwino akuthupi ndi mankhwala, sera imatha kugwiritsidwa ntchito kwambiri m'magulu onse amoyo.Chifukwa chakuti zinthuzo zimatha kukhala ndi malo ambiri osungunuka, kachulukidwe ndi zinthu zina, ndizomveka chifukwa chake zimagwiritsidwa ntchito kwambiri.
(1) Mitundu yodziwika bwino ndiyofunikira kwambiri pamsika wa nsalu.Amagwiritsidwanso ntchito popaka mapepala, zothandizira zikopa, makrayoni ndi zodzoladzola.Mitundu yopanda emulsifiable ndiyofala kwambiri posindikiza inki, pigment concentrate, ndi utoto.
(2) Mu gawo la nsalu, zida mwina ndizogwiritsa ntchito kwambiri.Mafuta odzola opangidwa ndi sera amapereka kufewetsa kokhazikika.Ngakhale kuti sagonjetsedwa ndi ma asidi ndi mankhwala ena, mafuta odzolawa ndi ogwirizana ndi nsalu - nsaluyo sikhala yachikasu, imasintha mtundu, kapena imasiya chlorine kumbuyo.
(3) Mumakampani a inki, zinthuzi zili ndi maubwino ofanana.Mitundu yambiri ya inki imakhala ndi sera ya polyethylene ngati njira yopititsira patsogolo kukangana ndikuwonjezera kukana.
(4) Sera ya polyethylene imagwiritsidwanso ntchito popanga zinthu.

Mapeto
Sera ya PE imakhala ndi kukhazikika kwamafuta, kusungunuka kochepa, kukana kwamankhwala ndi kuuma.Makhalidwewa, ophatikizidwa ndi kukana kuvala komanso kusungunuka kwakukulu, zimapangitsa kuti nkhaniyi ikhale chisankho chosatsutsika pamafakitale ambiri.Kaya mukufuna kukonza mphira, kupanga nsalu, mapulasitiki osinthidwa kapena makatoni okhala ndi malata, pali kalasi yoti musankhe.
