Noi oHydroxypropyl Methyl Cellulosema ka Pai Inika
Hoʻokumu ʻia ka inika me nā puaʻa, nā mea hoʻopili a me nā mea kōkua (hydroxypropyl methylcellulose), i hui ʻia a ʻōwili ʻia.
Mākaukau e ʻīnika. ʻO ka waihoʻoluʻu, ke kino (ʻo ka mea maʻamau nā waiwai rheological o ka inika e like me ke ʻano lahilahi a me ka wai i kapa ʻia ʻo ke kino o ka inika) a ʻo ka hana hoʻomaloʻo ʻo ia nā waiwai nui ʻekolu o ka inika.
ʻO ka hydroxypropyl methylcellulose koke no ka paʻi ʻīnika he pauka keʻokeʻo ʻole, ʻono ʻole, ʻona ʻole.
Huhū ʻo ia i loko o kahi ʻoluʻolu colloidal maʻemaʻe a ʻeleʻele paha i loko o ka wai anuanu. Loaʻa iā ia nā hiʻohiʻona o ka mānoanoa, ka hoʻopaʻa ʻana, ka dispersing, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention and protective colloid. he kuleana koʻikoʻi ma.

ʻO ka Hydroxypropyl methylcellulose he ʻekolu viscosities o 100,000, 150,000, a me 200,000. ʻO ka viscosity ke ʻano o ka kahe wai inika.
He hōʻailona o ka nui o ke kū'ē (a i ʻole ke kuʻekuʻe kūloko) i ka neʻe. I ke kaʻina hana o ka paʻi offset, pono kekahi viscosity e mālama mau i ka hoʻoili ʻana o ka inika.
ʻO ia ke kūlana koʻikoʻi no ka lawe ʻana a me ka hoʻoili ʻana, a he kūlana koʻikoʻi nō hoʻi ia no ka hoʻoholo ʻana i ka wikiwiki, māmā a me ka nani o ka paʻi. Inika viscosity
Inā nui loa, paʻakikī ka hoʻoili ʻana a me ka hoʻoili ʻana, no laila ʻaʻole lawa ka nui o ka inika ma ka hoʻolālā, e hopena i ka ʻōlohelohe o nā kiʻi a me nā kikokikona e hana i kahi kumu. Pēlā nō, viscosity
Inā ʻoi aku ka nui, maʻalahi hoʻi e hoʻoheheʻe ʻia ka pepa a pauka, a i ʻole ka ʻili ʻana o ka pepa i paʻi ʻia. Akā inā liʻiliʻi ka viscosity, maʻalahi ka hana
ʻO ka lana ʻana a me ka lepo, e hana ia i ka emulsification ink i nā hihia koʻikoʻi, inā ʻaʻole hiki ke mālama i ka hoʻoili maʻamau a me ka hoʻoili ʻana, a me ka mālie i ka inika.
Hōʻiliʻili nā ʻāpana puaʻa ma luna o nā wili, paʻi ʻana i nā papa a me nā pākeke, a ke piʻi ka hōʻiliʻili i kahi pae, e kumu ia i ka smudging.

Hydroxypropyl methyl celluloseloaʻa i ka adhesion maikaʻi, e pale ana i ka hoʻopili ʻana o ka inika i ka wā o ka paʻi ʻana
ʻAʻole kūpono ia i ka hana a me nā kūlana paʻi o ka substrate, ka hopena i ka pauka pepa, ka lint, ka ʻīnika maikaʻi ʻole, ka paʻi.
Paʻi ʻole e like me nā papa lepo.

He thixotropy maikaʻi ka Hydroxypropyl methylcellulose, e pale ana i ka thixotropy o ka inika i ka wā o ka paʻi ʻana.
ʻO nā hemahema o ka paʻi ʻana e like me ka "kahe ʻīnika maikaʻi ʻole", ka hoʻoili ʻana i ka inika like ʻole, a me ka hoʻonui nui ʻana o nā kiko i hoʻokumu ʻia e ka hewa.

ʻO ka Hydroxypropyl methylcellulose ka hoʻopili kiʻekiʻe loa, i ke kaʻina o ka paʻi offset, ʻaʻole pololei ka ikaika o ka ʻīnika.
E pili ana i ka hopena paʻi a me ka maikaʻi o ka huahana i paʻi ʻia, a pili pū kekahi i ka nui o ka inika no kēlā me kēia wahi. Inā koho ʻoe
ʻO ka hoʻohana ʻana i nā inika me ka ikaika o ka ʻoni ikaika e hoʻopau ʻia ka ʻīnika ma mua o nā inika me ka ikaika o ka ʻili palupalu, a hiki ke loaʻa nā hopena paʻi maikaʻi.

Hydroxypropyl methylcelluloseLoaʻa ka wai maikaʻi loa, ka inika fluidity kūpono, a me ka pae ʻana i ka punawai inika
Loaʻa iā ia ka mana inking maikaʻi a me ka hiki inking maikaʻi; maikaʻi nō hoʻi ka hoʻoili ʻana a me ka hoʻoili ʻana ma waena o nā wili inika a i ʻole ma waena o ka paʻi paʻi a me ka pākeke;
ʻAʻahu like ka ʻīnika; palahalaha a pahee ke kiʻi inika i paʻi ʻia. Inā liʻiliʻi ka wai, maʻalahi ka hoʻokuʻu ʻana i ka inika; ka mahele like ole o ka papa inika, etc.
ʻike ʻia ka ʻili o ke kiʻi ʻīnika i paʻi ʻia i nā nalu. I ka nui loa o ka wai, ua maʻalahi ka ʻīnika lahilahi e hoʻonui i ke kiko, paʻi
ʻAʻole ikaika ke kala. Hoʻohana mau ʻia ke ʻano mika kahe.
