Hōʻike Kūlana-ASTM e466 Sodium Carboxymethylcellulose

ʻO ASTM E466 kahi ʻano hoʻokolohua maʻamau e hāʻawi i kahi kaʻina hana no ka hoʻoholo ʻana i ka viscosity o ka sodium carboxymethylcellulose (CMC) i ka wai a i ʻole nā ​​​​mea hoʻonā. Hoʻohana maʻamau ʻia kēia ʻano e ana i ka degere o ka polymerization a me ke kiʻekiʻe o ka hoʻololi ʻana o CMC, a me ka hōʻoia ʻana i ka kūlike o nā laʻana CMC no nā kumu hoʻomalu maikaʻi.

ʻO ke ʻano o ka hoʻāʻo ʻana e hoʻomākaukau i kahi hopena o CMC i ka wai a i ʻole kekahi mea hoʻoheheʻe kūpono a me ke ana ʻana i kona viscosity me ka viscometer. Hoʻopili ʻia ka viscosity i kahi mahana kikoʻī a me ka shear rate, i kuhikuhi ʻia i ka maʻamau. Hāʻawi ka maʻamau i nā alakaʻi no ka hoʻomākaukau ʻana i ka hopena CMC, a me nā ʻōlelo kuhikuhi no ka calibrating a me ka hana ʻana i ka viscometer.

Ma waho aʻe o ke ana ʻana i ka viscosity, ʻo ka maʻamau ASTM E466 pū kekahi i nā kaʻina hana no ke ana ʻana i nā waiwai ʻē aʻe o CMC, e like me ka pH, ka ʻona lehu, a me ka ʻoluʻolu. Hiki i kēia mau waiwai ke hoʻopili i ka hana o CMC i nā noi like ʻole, a he mea nui ia e hōʻoia e hoʻokō lākou i nā kikoʻī i koi ʻia.

Ma ka holoʻokoʻa, hāʻawi ka maʻamau ASTM E466 i kahi ala maʻamau a hilinaʻi hoʻi no ke ana ʻana i ka viscosity a me nā waiwai ʻē aʻe o ka sodium carboxymethylcellulose. Kōkua kēia i ka hōʻoia i ka kūlike a me ka maikaʻi o nā huahana CMC a hiki i nā mea hana ke hoʻokō i nā pono o kā lākou mea kūʻai aku ma nā ʻoihana like ʻole.
