Ma muli o nā kumu like ʻole, ua piʻi aʻe ke kaulahao ʻoihana kemika, a ua piʻi aʻe nā kumukūʻai o nā ʻumi o nā mea maka.Ke hoʻomau nei ka ʻoihana huahana maʻemaʻe i kēia makahiki a pili pono.
Nui nā mea hoʻolako i nā mea maka a me nā mea kōkua (me nā polymers, spandex, nā lole i ulana ʻole ʻia, a me nā mea ʻē aʻe) i ka ʻoihana hoʻomaʻemaʻe i hoʻolaha i ka piʻi ʻana o ke kumukūʻai.ʻO ke kumu nui o ka hoʻonui ʻana, ʻo ia ka hemahema o nā kumu waiwai o luna a i ʻole ka piʻi mau ʻana o nā kumukūʻai.Ua ʻōlelo kekahi ma mua o ke kau ʻana i kahi kauoha Pono e kūkākūkā hou.
Ua manaʻo ka poʻe he nui: Ua piʻi ke kumukūʻai o uka, ʻo ka leka hoʻonui kumu kūʻai mai ka mea hana huahana i hoʻopau ʻia ma hope loa?
Aia kekahi ʻoiaʻiʻo i kēia kuhi.E noʻonoʻo e pili ana i ke ʻano a me nā mea maka o nā diapers, nā kāwele hoʻomaʻemaʻe, a me nā holoi pulu.
ʻO nā lole holoi lole ʻaʻole i ulana ʻia, ʻoiai ʻo nā diapers a me nā kāwele hoʻomaʻemaʻe maʻamau he ʻekolu mau mea nui: ʻo ka papa luna, ka papa hoʻoheheʻe, a me ka papa lalo.Hoʻopili kēia mau hale nui i kekahi mau mea kemika.
1. papa ili: hoʻonui kumukūʻai lole non-woven
ʻO ka lole i ulana ʻole ʻia ʻaʻole wale ka mea ma luna o nā diapers a me nā napkin maʻemaʻe, akā ʻo ka mea nui hoʻi o nā holoi holoi.ʻO nā lole i ulana ʻole ʻia i hoʻohana ʻia i nā huahana maʻemaʻe hoʻopau ʻia i hana ʻia me nā fiber kemika me ka polyester, polyamide, polytetrafluoroethylene, polypropylene, carbon fiber, a me ke aniani fiber.Ua hōʻike ʻia e piʻi ana kēia mau mea kemika i ke kumukūʻai, no laila e piʻi maoli ke kumukūʻai o nā lole i ulana ʻole ʻia me kona uka, a no ke kumu hoʻokahi, e piʻi pū ana nā huahana i hoʻopau ʻia o nā huahana maʻemaʻe.
2. Absorbing layer: piʻi ke kumukūʻai o ka mea absorbent SAP
ʻO SAP ka mea nui i haku ʻia o ka papa hoʻoheheʻe ʻana o nā diapers a me nā napkin maʻemaʻe.ʻO ka resin hoʻoheheʻe wai Macromolecular he polymer me nā waiwai hoʻoheheʻe wai i polymerized e nā monomers hydrophilic.ʻO ka mea maʻamau a ʻoi aku ka liʻiliʻi o ia monomer ʻo ia ka waikawa acrylic, a ʻo ka propylene ka mea i loaʻa mai ka pohā o ka ʻaila.Ua piʻi ke kumukūʻai o ka aila, a me ke kumukūʻai o ka waikawa acrylic Ma hope o ka piʻi ʻana, e piʻi maoli ka SAP.
3. Papa lalo: hoʻonui kumu kūʻai o ka polyethylene maka
ʻO ka papa lalo o nā diapers a me nā napkin maʻemaʻe he kiʻi ʻoniʻoni i haku ʻia, i haku ʻia me kahi kiʻi ʻoniʻoni ma lalo breathable a me kahi lole i ulana ʻole ʻia.Ua hōʻike ʻia ʻo ke kiʻi ʻoniʻoni ma lalo he kiʻi plastik i hana ʻia mai ka polyethylene.(PE, kekahi o na ano nui o ka plastic, ua synthesized mai polyethylene Polymer material.) A ethylene, e like me ka mea maʻamau hoʻohana petrochemical huahana, ua nui hoʻohana 'ia no ka plastic raw material polyethylene.Ke hōʻike nei ka ʻaila ʻaila i kahi ʻano piʻi, a ke piʻi aʻe ke kumukūʻai o nā membrane hanu e hoʻohana ana i ka polyethylene ma ke ʻano he mea maka ke piʻi aʻe ke kumukūʻai o ka polyethylene.
ʻO ka piʻi ʻana o ke kumukūʻai o nā mea maka e hoʻokau i ke koʻikoʻi i ke kumukūʻai o nā mea hana huahana i hoʻopau ʻia.Ma lalo o kēia kaomi, ʻaʻohe mea i ʻoi aku ma mua o ʻelua mau hopena:
ʻO kekahi, ʻo nā mea hana huahana i hoʻopau ʻia e hōʻemi i ke kūʻai ʻana i nā mea maka i mea e hōʻemi ai i ke kaomi, e hōʻemi ana i ka hiki ke hana i nā diapers;
ʻO ka mea ʻē aʻe, ʻo nā mea hana i hoʻopau ʻia e kaʻana like i ke kaomi ma luna o nā ʻelele, nā mea kūʻai aku a me nā mea kūʻai aku.
I kēlā me kēia hihia, ʻike ʻia ka piʻi ʻana o ke kumukūʻai ma ka hopena kūʻai.
ʻOiaʻiʻo, he kuhi wale ka mea i luna.Manaʻo kekahi poʻe ʻaʻole hiki ke kūpaʻa kēia nalu o ka piʻi ʻana o ke kumukūʻai, a aia nō ka waihona e kākoʻo ai i ka terminal, a ʻaʻole hiki ke piʻi ʻia ke kumukūʻai o nā huahana i hoʻopau ʻia.I kēia manawa, ʻaʻohe mea hana huahana i hoʻopuka i nā leka hoʻonui kumukūʻai.
