Pane papa papaʻaina peʻahi

Me ka holomua o ka ʻenehana a me ka piʻi ʻana o nā haʻuki waho,nā papa ʻaina pepa ʻiliua hele malie mai i ka maka o kanaka.Ua lanakila ʻo ia i ka makemake o ka poʻe no kāna leo liʻiliʻi loa, ke kaumaha māmā a me ka hoʻohana maʻalahi ma hope o ka pelu ʻana.Hoʻokumu ʻia kahi pākaukau pelu me kahi papa a me kahi kiʻi.I kēia lā e hoʻolauna wau i ka mea o ka papa ʻaina pelu.

ʻO ka polyethylene kiʻekiʻe kiʻekiʻe (HDPE), kahi pauka keʻokeʻo a i ʻole nā ​​​​huahana granular.Non-toxic, tasteless, crystallinity of 80% to 90%, softening point of 125 to 135°C, lawelawe wela a hiki i 100°C;

ʻoi aku ka paʻakikī, ka ikaika tensile a me ke kolo ma mua o ka polyethylene haʻahaʻa haʻahaʻa;

ʻaʻahu kūʻokoʻa, uila ʻO ka insulation maikaʻi, ka paʻakikī a me ke kū anuanu;

paʻa kemika maikaʻi, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe i ka lumi wela, kū i ka corrosion i nā waikawa, alkalis a me nā paʻakai like ʻole;

ka kiʻiʻoniʻoni haʻahaʻa permeability i ka wai mahu a me ka ea, a me ka wai absorption Low;

ʻAʻole maikaʻi ka maikaʻi o ka pale ʻana i ka wā kahiko, ʻoi aku ka maikaʻi o ka pale ʻana i ke kaiapuni e like me ka polyethylene haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka thermal oxidation e hōʻemi i kāna hana,

no laila pono e hoʻohui ʻia nā antioxidants a me nā mea hoʻopili ultraviolet i ka resin e hoʻomaikaʻi i kēia hemahema.

ʻO ka kiʻiʻoniʻoni polyethylene kiʻekiʻe he haʻahaʻa haʻahaʻa distortion wela ma lalo o ke koʻikoʻi, no laila e mālama pono i ka wā e noi ai.

I kēia kenekulia, ua loaʻa kahi holomua kipi i ke kahua o nā pipeline, ʻo ia hoʻi, "hoʻololi i ke kila me ka plastic".Me ka holomua wikiwiki o ka ʻepekema a me ka ʻenehana polymer, ka hohonu o ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā paipu plastik, a me ka hoʻomau mau ʻana o ka ʻenehana hana, ua hōʻike piha nā paipu plastik i kā lākou hana maikaʻi loa.

I kēia mau lā, ʻaʻole kuhi hewa ʻia nā paipu plastik no nā "mea hoʻololi kūʻai" no nā paipu metala.I kēia hoʻololi ʻana, makemake ʻia nā paipu polyethylene a ke hoʻomāhuahua nei ka ʻālohilohi.Hoʻohana nui ʻia lākou i ka hoʻouna ʻana i ke kinoea, ka hoʻolako wai, ka hoʻokuʻu ʻana i ka wai, ka irrigation mahiʻai, ka lawe ʻana i nā mea paʻa paʻa i loko o nā mines, a me nā māla aila, nā mea kemika, ka pou a me ke kelepona, a me nā mea ʻē aʻe, ʻoi aku ka nui o nā kula e like me lawe kinoea.
