ʻO ke koʻikoʻi o ka paʻi mānoanoa

Paʻi mānoanoa: He ʻano mānoanoa i hoʻohana pinepine ʻia i ka ʻoihana paʻi.I ka paʻi ʻana, hoʻohana ʻia ʻelua mau mea nui, ke kāpili a me ka paʻi kala.A no ka mea ma lalo o ka ʻoki kiʻekiʻe, e hoʻemi ʻia ke kūlike, no laila pono e hoʻohana i kahi mānoanoa e hoʻonui ai i ke kūlike o ka mea paʻi, a laila hoʻohana ʻia ka mānoanoa paʻi.

ʻO ka hana nui o ka paʻi mānoanoa china ʻo ka hāʻawi ʻana i nā waiwai rheological maikaʻi, hoʻololi i ke kāpili a i ʻole ka paʻi kala ma ka pale paʻi a me ka roller paʻi i ka lole, hoʻohui i ka wai a me ka fiber, a hōʻoia i ka outline o ke ʻano paʻi.ʻokoʻa.Akaka ke kumu, ʻālohilohi a ʻaʻahu ke kala;ke hoʻopaʻa ʻia ke kala, hoʻoneʻe maʻalahi ka huahana hopena a me ke koena i ke kaʻina o lalo, me ka palupalu o ka lole.Hiki ke ʻike ʻia he kuleana koʻikoʻi ka mīkini paʻi paʻi i ka ʻoihana paʻi.

Moʻolelo Hoʻomohala:

He mōʻaukala lōʻihi ka hoʻomohala ʻana o nā mea paʻi mānoanoa.ʻO ka slurry i hoʻohana ʻia i ka wā kahiko he starch a i ʻole starch hoʻololi ʻia.Kapa ʻia kēia mānoanoa he mānoanoa maoli, akā ʻo kēia mānoanoa paʻi he kiʻekiʻe ka hoʻohana ʻana, haʻahaʻa ka hohonu o ka waihoʻoluʻu, maikaʻi ʻole, a me ke kūpaʻa ʻAʻole maikaʻi ka wikiwiki i ka holoi ʻana, a ʻaʻole ʻoluʻolu ke ʻano o ka lole.I kēia manawa, ua hoʻopau ʻia kēia mau ʻano mānoanoa.ʻO ka makahiki 1950 wale nō i hoʻolauna ai nā kānaka i ka pulp A-state, kahi i hoʻohana nui ʻia ai ka ʻenehana paʻi.Hoʻokumu ʻia kahi mānoanoa pulp mokuʻāina e ka emulsification kiʻekiʻe o ka kerosene a me ka wai ma lalo o ka hana o ka emulsifier.No ka mea, ʻoi aku ka nui o kēia mānoanoa ma mua o 50 # kerosene, a ʻo ka nui i hoʻohana ʻia, hoʻohaumia nui ia i ka lewa a me ka pilikia o ka pahū.Eia kekahi, ʻaʻole maʻalahi ka hoʻoponopono ʻana o ka paʻi paʻi, a e mau ke ʻala o ke kerosene ma ka lole ma hope o ka paʻi ʻana.No laila ʻaʻole ʻoluʻolu ka poʻe i kēia ʻano mea paʻi mānoanoa.

Paʻi mānoanoa

I ka makahiki 1970, hoʻomaka ka poʻe e hoʻomohala a hana i nā mānoanoa synthetic.ʻO ka hiki ʻana mai o nā mānoanoa synthetic ua hoʻoikaika nui i ka hoʻomohala ʻana i ka hana paʻi a hoʻonui i ka ʻenehana paʻi i kahi pae hou.Hoʻoponopono ia i nā pilikia o ka haumia a me ka palekana.Eia kekahi, ʻoi aku ka maikaʻi o ka mānoanoa synthetic o ka hopena mānoanoa maikaʻi, ka lawe ʻana a me ka mālama ʻana, ka hoʻomākaukau maʻalahi, ka outline maʻemaʻe, ke kala ʻulaʻula a pēlā aku.

Ka hoʻokaʻawale ʻana o ka mānoanoa paʻi:

Nui nā ʻano o nā mānoanoa paʻi, i kēia manawa i māhele ʻia i ʻelua mau ʻāpana nui: nonionic a me anionic.ʻO nā mea mānoanoa nonionic ka hapa nui o ka polyethylene glycol ether derivatives.Pono ka laulā o ia mau mānoanoa, akā maikaʻi ʻole ka hopena mānoanoa, ʻoi aku ka nui o ka hoʻohui ʻana, a koi ʻia kahi nui o ka aila.No laila, ke kaupalena nei kēia i kona hoʻomohala hou ʻana.

ʻO ka anionic mānoanoa he polymer electrolyte pūhui, ʻo ia ka copolymer me ka māmā crosslinking.Hōʻike ʻia ia e ka viscosity haʻahaʻa, ka hopena mānoanoa maikaʻi, kūpaʻa maikaʻi, hoʻohui haʻahaʻa, rheology maikaʻi, a me ka hopena paʻi.maikaʻi loa.ʻO ka mea maʻamau he polyacrylic pūhui.I kēia manawa, ʻo ka mea maʻamau polyacrylic acid pūhui he anionic polymer electrolyte.Hoʻohana ia i ke ʻano polymerization emulsion e hoʻopololei maikaʻi i nā monomers wai-soluble i nā huahana waiū.He mea maʻalahi no ka hana ʻana i ka paʻi a me ka paʻa o ka paʻi kumu a me ka paʻi kala.He palupalu ka lole i pai ʻia a hiki ke mālama ʻia no ka manawa lōʻihi.ʻO ia ka mea a mākou e ʻōlelo pinepine ai e pili ana i ka mānoanoa PTF.
