He aha ka HDPE?

Ua wehewehe ʻia ka HDPE e ka mānoanoa o ka nui a i ʻole like me 0.941 g/cm3. He haʻahaʻa haʻahaʻa ka HDPE o ka lālā a no laila ʻoi aku ka ikaika o nā pūʻali intermolecular a me ka ikaika tensile. Hiki ke ho'opuka 'ia ka HDPE e ka chromium/silica catalysts, Ziegler-Natta catalysts a me ka metallocene catalysts. ʻO ka nele o ka lālā e hōʻoia ʻia e kahi koho kūpono o ka catalyst (e laʻa me ka chromium catalysts a i ʻole Ziegler-Natta catalysts) a me nā ʻano hopena.

Hoʻohana ʻia ʻo HDPE i nā huahana a me nā ʻeke e like me nā hue waiu, nā ʻōmole detergent, nā pahu margarine, nā ipu ʻōpala a me nā paipu wai. Hoʻohana nui ʻia ʻo HDPE i ka hana ʻana i ke ahi. I loko o nā paipu ʻokoʻa ka lōʻihi (ma muli o ka nui o ka ordnance), hoʻohana ʻia ʻo HDPE ma ke ʻano he pani no nā pahu pahu pahu pahu i hoʻolako ʻia no nā kumu kumu ʻelua. ʻO ka mea hoʻokahi, ʻoi aku ka palekana ma mua o nā paipu pepa i hoʻolako ʻia no ka mea inā e hana ʻino ka pūpū a pahū i loko ("pota pua") kahi paipu HDPE, ʻaʻole e haki ka paipu. ʻO ke kumu ʻelua, ʻo ia ka mea hiki ke hoʻohana hou ʻia e hiki ai i nā mea hoʻolālā ke hana i nā pahu mortar pana. ʻAʻole ʻae ka poʻe Pyrotechnic i ka hoʻohana ʻana i ka paipu PVC i loko o nā paipu mortar no ka mea ʻo ia ka mea e ʻāhaʻi, e hoʻouna ana i nā ʻāpana o ka plastic i nā mea nānā aku, ʻaʻole e hōʻike ʻia i nā hihi-X.
