Chitetezo ndi kulimba ndi zinthu ziwiri zazikulu zomwe kholo lililonse ndi womulera amasamala posankha zida zoyenera za zida zoseweretsa za ana. Apa ndipamene mapepala apulasitiki amitundu iwiri a HDPE amabwera ndikupereka yankho langwiro.
Zithunzi za HDPE, yomwe imadziwikanso kuti polyethylene yapamwamba kwambiri, ndizitsulo zapulasitiki zomwe zimagwiritsidwa ntchito kwambiri zomwe zimadziwika ndi mphamvu zake komanso kulimba kwake. Imagonjetsedwa ndi mphamvu, mankhwala ndi ma radiation a UV, ndikupangitsa kuti ikhale yabwino kwa ntchito zakunja. Kupepuka kwake kumapangitsanso kuti ikhale yosavuta kunyamula ndi kunyamula, ndikuwonjezera kusavuta kwake.
Chimodzi mwazinthu zodziwika bwino zaHDPE pepala lapulasitiki lamitundu iwirindi sangweji mawonekedwe atatu wosanjikiza. Kumanga kumeneku kumapereka mphamvu zowonjezera ndi kulimba kwa mapepala, kuonetsetsa kuti akhoza kupirira kusuntha kwamphamvu ndi nyengo yovuta. Zimapangitsanso kuti mapepalawo asagwedezeke ndi kupindika, kuonetsetsa chitetezo cha ana pamene akusewera.
Mapulogalamu apulasitiki amitundu iwiriwa samangogwira ntchito komanso okongola. Ndi mitundu yawo yowoneka bwino komanso kumaliza kwake kosalala, kumapangitsa chidwi cha zida zoseweretsa zapamunda za ana. Zitha kupangidwa mosavuta m'mawonekedwe ndi makulidwe osiyanasiyana, zomwe zimalola opanga kupanga mapangidwe owoneka bwino omwe amakopa chidwi cha ana.
Kuphatikiza apo,HDPE pepala lapulasitiki lamitundu iwirindi wokonda zachilengedwe komanso wokhazikika. Zilibe zinthu zovulaza monga mtovu ndi makemikolo, zomwe zimateteza ana komanso zimathandiza kuti chilengedwe chikhale chathanzi. Moyo wawo wautali komanso kukana kuvala kumatanthauzanso kuti amakhala nthawi yayitali, kuchepetsa kufunika kosinthidwa pafupipafupi komanso kuchepetsa kutulutsa zinyalala.
Pankhani yokonza, mapanelo apulasitikiwa ndi osavuta kuyeretsa. Kupukuta kosavuta ndi madzi a sopo ndikokwanira kuti aziwoneka ngati atsopano. Amakhalanso osagonjetsedwa ndi madontho ndi graffiti, yomwe ndi mwayi wowonjezera malo a anthu ndi malo osewerera.
Mukamagula mapepala apulasitiki amitundu iwiri a HDPE pazida zoseweretsa za ana m'munda, ndikofunikira kuwonetsetsa kuti zinthuzo zikugwirizana ndi mfundo zachitetezo ndi malamulo. Yang'anani ziphaso monga ASTM ndi EN71, zomwe zimatsimikizira kuti bolodi yayesedwa mphamvu yamakina, yopanda poizoni komanso kukana moto.
Pomaliza,Zithunzi za HDPEpepala lapulasitiki lamitundu iwiri ndi chisankho chabwino kwambiri pazida zoseweretsa za ana. Mapangidwe awo a masangweji atatu ophatikizidwa ndi mphamvu ndi kulimba kwa HDPE zimatsimikizira moyo wawo wautali komanso chitetezo kuti ana azisewera nawo. Mapepalawa ndi okongola, osavuta kusamalira, komanso okonda zachilengedwe, amawonjezera kukopa komanso magwiridwe antchito a sewero lililonse lakunja. Gulani matabwa apulasitiki amitundu iwiri a HDPE tsopano ndipo mubweretsere ana masewera otetezeka komanso osangalatsa.
