Ma ke ʻano he paipu plastik -ʻoihana kiʻekiʻe, hoʻohana nui ʻia ka paipu polyurethane ma nā ʻoihana a me nā kula kīwila ma ka honua holoʻokoʻa. ʻO kāna mau hiʻohiʻona ʻenehana e lilo ia i huahana hoʻolaha kaulana. Hōʻike ka paipu Polyurethane i ka hoʻokūkū ikaika i nā ʻoihana he nui ma muli o kāna mau waiwai kino maikaʻi a me ke kūpaʻa kemika, ʻoi aku hoʻi i nā mākeke o waho e like me ʻEulopa, ʻAmelika, Middle East, a me Asia Hikina Hema.
Mai ka hiʻohiʻona waiwai, ʻoi loa ka pale ʻana o ka ʻaʻahu polyurethane, 3 a 5 mau manawa o ko nā paipu ʻōpala maʻamau, no laila kūpono ia no ka lawe ʻana i ka wai ma nā ʻaʻahu kiʻekiʻe. I ka manawa like, loaʻa i kēia mea ka maʻalahi maikaʻi, mālama i ka hopena maikaʻi loa i ka haʻahaʻa haʻahaʻa a me ka pale ʻana i ka haki ʻana. ʻOi aku ka maikaʻi o kēia hiʻohiʻona ma nā wahi anu a i ʻole nā piʻi wela. Eia kekahi, ʻo ka paipu polyurethane he haʻahaʻa haʻahaʻa o ka friction, e hōʻemi pono i ke kūʻē ʻana i ka wā o ka lawe ʻana i ka wai a me ka hoʻomaikaʻi ʻana i ka pono o ka halihali.
Ma ke ʻano o ke kūpaʻa kemika, ʻoi aku ka maikaʻi o ka paipa polyurethane i ka hapa nui o nā waikawa, alkalis, a me nā solvents, kūpono ia no nā ʻoihana e like me ke kemika, petroleum, a me nā lāʻau lapaʻau. ʻOi aku ka maikaʻi o kona kūpaʻa hydrolysis, e mālama ana i ka hana paʻa - lōʻihi ma nā wahi haʻahaʻa. I kēia manawa, māmā a maʻalahi ka hoʻokomo ʻana o nā paipu polyurethane, e hōʻemi nui ana i nā kumukūʻai o ka lawe ʻana a me ke kūkulu ʻana, e hoʻokō ana i nā koi o ka ʻoihana hou no nā hopena maikaʻi a haʻahaʻa -uku.
Ma ka mākeke kalepa ʻē aʻe, ua lilo nā paipu polyurethane, me ko lākou kumu kūʻai kiʻekiʻe -ka maikaʻi a me ka hoʻohana ākea, ua lilo ia i mea makemake no ke kūkulu ʻana i nā ʻoihana, ka hana ʻenehana, a me ka hoʻoulu wai ʻana i nā ʻāina he nui. Me ka hoʻonui nui ʻana o ka ʻenehana ʻoihana honua a me nā koi palekana kaiapuni, ke hoʻomau nei ka ulu ʻana o ka mākeke no nā paipu polyurethane, ʻoi aku hoʻi i ka -hopena hana kiʻekiʻe a me nā ʻāpana ikehu ʻōmaʻomaʻo, kahi e hōʻike nui ʻia ai ko lākou mau pono ʻenehana. No nā ʻoihana kalepa ʻē aʻe, ʻo ka ʻike piha ʻana i nā hiʻohiʻona ʻenehana o nā paipu polyurethane, i hui pū ʻia me nā pono kikoʻī o nā mākeke pahuhopu, kōkua i ka hoʻoikaika ʻana i ka hoʻokūkū huahana a hoʻonui i nā mākeke honua ākea.
