E hoʻonui paha i ka viscosity o cellulose ether i ka kahe kahe?

ʻO ka hoʻonui ʻana i ka viscosity o cellulose ethers e hoʻemi maʻamau i ka kahe kahe o ka hopena. ʻO nā cellulose ethers kahi hui o nā polymers wai-soluble i loaʻa mai ka cellulose i hoʻohana mau ʻia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ke kūkulu ʻana. ʻO ka viscosity o kahi hoʻonā kahi ana o kona kūʻē ʻana i ke kahe a pili ʻia e nā mea e like me ka ʻike, ka mahana, a me ke kaumaha mole o ka cellulose ether.

Eia ka wehewehe kikoʻī e pili ana i ka hoʻonui ʻana i ka viscosity cellulose ether e pili ana i ka kahe kahe.

ʻO ka pilina ma waena o ka viscosity a me ke kahe kahe:

ʻO ka viscosity ka hāliʻi kūloko i loko o kahi wai e kūʻē i kona kahe. Ana ʻia ia ma nā ʻāpana e like me centipoise (cP) a i ʻole kekona pascal (Pa·s).
ʻO ke kahe kahe o ka hoʻonā ʻano like ʻole me kona viscosity. ʻO ka viscosity kiʻekiʻe ke ʻano o ke kūʻē ʻana i ke kahe, e hopena i nā kahe kahe haʻahaʻa.

Nā waiwai o ka cellulose ether:

Hoʻohui pinepine ʻia nā cellulose ethers i ka hopena e hoʻololi i kāna mau waiwai rheological. ʻO nā ʻano maʻamau ka methylcellulose (MC), hydroxypropylcellulose (HPC), a me ka carboxymethylcellulose (CMC).
ʻO ka viscosity o ka cellulose ether solution e pili ana i nā mea e like me ka neʻe ʻana, ka mahana a me ka helu shear.

Ka hopena hoʻopaʻa ʻana:

ʻO ka hoʻonui ʻana i ka ʻike o ka cellulose ethers e hoʻonui i ka viscosity. No ka mea, ʻoi aku ka nui o nā kaulahao polymer i loko o ka hoʻonā, ʻoi aku ka nui o ke kūpaʻa kahe.

Ka hopena wela:

Hoʻopilikia ka mahana i ka viscosity o cellulose ethers. I kekahi mau hihia, i ka piʻi ʻana o ka mahana, e emi ana ka viscosity. Eia nō naʻe, ʻokoʻa paha kēia pilina ma muli o ke ʻano cellulose ether kikoʻī a me kāna mau mea hoʻonā.

ʻO ka hilinaʻi o ka shear rate:

ʻO ka viscosity o nā hoʻonā cellulose ether e hilinaʻi maʻamau i ka nui o ka shear rate. I ka ʻoi aku o ka nui o ka ʻoki ʻoki (no ka laʻana, i ka wā o ka pahū ʻana a i ʻole ka hui ʻana), hiki ke emi mai ka viscosity ma muli o ke ʻano o ka ʻohi ʻana.

Ka hopena ma ke kaʻahele:

ʻO ka hoʻonui ʻana i ka viscosity cellulose ether hiki ke hōʻemi i nā kahe kahe ʻana i nā kaʻina e pono ai ka lawe ʻana, pumping, a i ʻole ka hāʻawi ʻana i nā hopena. He kūpono kēia no nā noi e like me ka uhi ʻana, nā mea hoʻopili a me nā ʻano lāʻau lapaʻau.

palapala noi:

ʻOiai e koi ʻia nā viscosities kiʻekiʻe ma kekahi mau noi e hoʻomaikaʻi i ka hana a i ʻole ka paʻa ʻana o ka huahana, pono e kaulike ʻia kēia me nā ʻano hana o ka lawelawe ʻana a me ka hana ʻana.

ʻO ka hoʻomaʻamaʻa meaʻai:

Hoʻomaʻamaʻa pinepine nā mea hoʻopuka i ka cellulose ether concentration a me nā ʻāpana hoʻonohonoho ʻē aʻe e hoʻokō i ka viscosity i koi ʻia no kahi noi kikoʻī me ka ʻole o ka pili ʻana i ka flowability i kahi pae ʻae ʻole.

ʻO ka hoʻonui ʻana i ka viscosity cellulose ether e hopena maʻamau i ka emi ʻana o ka kahe kahe ma muli o ka piʻi ʻana o ke kahe kahe. Eia nō naʻe, pili ka pilina pololei e nā mea e like me ka noʻonoʻo ʻana, ka mahana a me ka nui o ka shear, a hiki ke hana ʻia nā hoʻoponopono hoʻoponopono e hoʻokō i ke kaulike i makemake ʻia ma waena o ka viscosity a me ka flowability.
