Hoʻolauna Huahana CMC no ka Paʻi Paʻi Reactive

1. Sodium Carboxymethyl Cellulose
ʻO ka pāpaʻi paʻi Reactive kahi derivative me ka ether structure i loaʻa ma o ka hoʻololi kemika o ka cellulose maoli. He mea hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela. Loaʻa i kāna mea hoʻonā wai nā hana o ka hoʻopaʻa ʻana, ka mānoanoa, ka hoʻopuehu, ka hoʻokuʻu ʻana a me ka hoʻopaʻa ʻana.

He huahana o ka sodium carboxymethyl cellulose me kahi kiʻekiʻe o ka etherification. ʻO ke kaʻina hana kūikawā e hoʻololi piha i kāna pūʻulu hydroxyl mua, i mea e pale aku ai i ka hopena me nā dyes reactive.

E like me ka mānoanoa o ka paʻi paʻi, reactive paʻi paʻi hiki ke hoʻopaʻa i ka viscosity, hoʻomaikaʻi i ka wai o ka paʻi, hoʻonui i ka hydrophilic hiki o ke kala, hana i ka lole dyeing a hoʻemi i ka ʻokoʻa kala; i ka manawa like, i ka holoi ʻana ma hope o ka paʻi ʻana a me ke kala, ʻoi aku ka kiʻekiʻe o ka holoi ʻana, ʻoluʻolu ka lole i ka paʻi.

2. Hoʻohālikelike i nā ʻano o ka paʻi paʻi reactive a me ka sodium alginate
2.1 Hoʻopili i ka helu

Ke hoʻohālikelike ʻia me ka sodium alginate, ʻoi aku ka kiʻekiʻe o ka viscosity paʻi reactive, inā hoʻohana wale ʻia a i hui pū ʻia me nā mānoanoa ʻē aʻe, hiki iā ia ke hoʻemi pono i ke kumukūʻai o ka paʻi; ʻO ka mea maʻamau, ʻo ka paʻi paʻi ikaika ʻO ka dosage he 60-65% wale nō o ka sodium alginate.

2.2 Hua kala a me ka manaʻo

ʻO ka waihoʻoluʻu o ka paʻi paʻi i hoʻomākaukau ʻia me ka paʻi paʻi reactive e like me ka mānoanoa e like me ka sodium alginate, a palupalu ka lole ma hope o ka hoʻopau ʻana, ua like ia me nā huahana pāpaʻi sodium alginate.

2.3 Hoʻopili paʻa

ʻO ka sodium alginate kahi colloid maoli, ʻaʻohe ʻae maikaʻi i nā microorganisms, ka manawa mālama pōkole o ka paʻi kala, a maʻalahi ke hao. ʻOi aku ka maikaʻi o nā huahana sodium carboxymethyl cellulose ma mua o ka sodium alginate. Ua hoʻomaikaʻi ʻia nā huahana paʻi paʻi reactive e kahi kaʻina hana kūikawā, a ʻoi aku ka maikaʻi o kā lākou pale electrolyte ma mua o nā huahana sodium carboxymethyl cellulose maʻamau. I ka manawa like, loaʻa iā lākou ka hoʻohālikelike maikaʻi ʻana me nā mea kōkua kemika a me nā mea hoʻonaninani, ʻaʻole maʻalahi e hoʻopōʻino a hoʻopōʻino i ka wā mālama. ʻOi aku ka maikaʻi o ka paʻa kemika ma mua o ka sodium alginate.

2.4 Rheology (hoʻohui)

ʻO ka sodium alginate a me ka CMC he mau wai pseudoplastic, akā ʻo ka sodium alginate he haʻahaʻa haʻahaʻa viscosity a me ka waiwai PVI kiʻekiʻe, no laila ʻaʻole kūpono ia no ka paʻi ʻana i ka pale (flat), ʻoi aku ka paʻi kiʻekiʻe-mesh; ʻO nā huahana paʻi paʻi paʻi kiʻekiʻe ka viscosity kiʻekiʻe, ʻo ka waiwai PVI e pili ana i 0.5, maʻalahi e paʻi i nā kumu a me nā laina. ʻO ka hui pū ʻana o ka sodium alginate a me ka paʻi paʻi ikaika hiki ke hoʻokō i nā koi rheological hou o ka paʻi paʻi
