Hydroxypropyl Methylcellulose (HPMC)

ʻO ka Hydroxypropyl Methyl Cellulose i ʻike mau ʻia ʻo Hypromellose, HPMC, he ether cellulose non-ionic i loaʻa mai i nā polymers maoli e like me ka pulupulu hoʻomaʻemaʻe a i ʻole ka pulp lāʻau ma o ke kaʻina hana kemika. Hōʻike ʻia ma ke ʻano he pauka keʻokeʻo ʻole, ʻona ʻole, a ʻono ʻole. Hiki ke hoʻoheheʻe ʻia kēia mea i loko o ka wai wela a me ka wai anuanu, e hana ana i kahi hopena viscous akaka me nā ʻano waiwai like ʻole, e ʻimi nui ʻia no nā noi like ʻole.

Hāʻawi ka HPMC i nā hiʻohiʻona kūikawā e like me ka mānoanoa maikaʻi, hoʻopaʻa, hoʻopuehu, emulsifying, hana kiʻiʻoniʻoni, hoʻokuʻu, adsorbing, gelling, surface-active, mālama wai, a me ka pale ʻana i nā waiwai colloid. ʻO kona hoʻohana nui ʻana ma waena o nā ʻoihana e pili ana i ke kūkulu ʻana, nā lāʻau lapaʻau, nā meaʻai, PVC, keramika, a me nā huahana mālama pilikino/home.

Ma ka ʻoihana kūkulu, lawelawe ʻo HPMC ma ke ʻano he mānoanoa no nā mortar drymix, nā mea hoʻopili tile, nā pena i hoʻokumu ʻia i ka wai, ka putty pā, a me nā moʻo mortar insulation thermal. Eia kekahi, loaʻa iā ia ka noi ma ke ʻano he lāʻau lapaʻau a me ka meaʻai meaʻai, e hāʻawi ana i ka hana ʻana o PVC, keramika, a me nā mea holoi. He mea maʻamau ka HPMC i nā lole lole, nā huahana mālama pilikino, a me nā mea mālama home.

He aha ka Hydroxypropyl Methylcellulose i hoʻohana ʻia no?

wehewehe2

ʻO ka Hydroxypropyl Methylcellulose (HPMC) he polymer versatile me kahi ākea o nā noi ma nā ʻoihana like ʻole. ʻO kāna mau waiwai kūʻokoʻa he mea waiwai ia i nā ʻano hana like ʻole. Eia kekahi mau hoʻohana maʻamau o Hydroxypropyl Methylcellulose:

He aha nā waiwai nui o HPMC?

wehewehe2

ʻO ka Hydroxypropyl Methylcellulose (HPMC) he cellulose derivative me nā ʻano waiwai e pono ai i nā ʻoihana like ʻole. Eia nā waiwai maʻamau o HPMC:

Hoʻolālā Kimia:

ʻO ka HPMC he polymer semi-synthetic i loaʻa mai ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu.

ʻO ka hana kemika o HPMC e pili ana i nā hui hydroxypropyl a me methyl i hoʻopili ʻia i ka iwi kuamoʻo cellulose.

Hiki ke hoʻoheheʻe:

Hiki ke hoʻoheheʻe ʻia ka HPMC i loko o ka wai, e hana ana i kahi hopena maʻemaʻe, e maʻalahi ai ke hoʻohui ʻia i loko o nā ʻano wai.

viscosity:

ʻO kekahi o nā waiwai koʻikoʻi o HPMC ʻo kona hiki ke hoʻololi i ka viscosity. Hiki iā ia ke hāʻawi i ka mānoanoa i nā hoʻonā a me nā hoʻoponopono, e hāʻawi i ka hoʻomaikaʻi ʻana i ke ʻano a me ka hana.

Hana Kiʻiʻoniʻoni:

Loaʻa i ka HPMC nā waiwai hana kiʻiʻoniʻoni, kahi e pono ai i nā noi kahi e makemake ʻia ai ke kūkulu ʻana i kahi kiʻiʻoniʻoni pale a i ʻole cohesive.

ʻO ka wai wela:

Hōʻike ka HPMC i ka gelation thermal, ʻo ia hoʻi ka piʻi ʻana o kona viscosity me ka mahana. Hoʻohana pinepine ʻia kēia waiwai i ka hoʻokuʻu ʻana i ka lāʻau lapaʻau.

Hana i luna:

Hiki i ka HPMC ke loaʻa nā waiwai e like me ka surfactant, hoʻonui i ka emulsification a me ka hoʻopuehu ʻana i kekahi mau formulations.

Paʻa:

Hāʻawi ka HPMC i ka paʻa o nā hoʻokuʻu ʻana, nā emulsions, a me nā ʻano hana ʻē aʻe ma ka pale ʻana i ka hoʻonohonoho ʻana a i ʻole ka hoʻokaʻawale ʻana.

Paʻa wai:

Loaʻa i ka HPMC ka hiki ke mālama i ka wai, i mea waiwai i nā noi kahi e pono ai ka mālama ʻana i ka wai, e like me nā mea hana.

Hoʻopili:

Ma nā ʻoihana like ʻole, hoʻomaikaʻi ʻo HPMC i ka hoʻopili ʻana, inā i loko o nā mea hana e like me nā morta a i ʻole nā pale a me nā adhesives.

Kemikini inertness:

ʻO ka HPMC he chemically inert, ʻo ia hoʻi, ʻaʻole ia e ʻae me nā mea ʻē aʻe i loko o ka hoʻokumu ʻana, e hōʻoiaʻiʻo ana i ka paʻa a me ka hoʻohālikelike ʻana me nā ʻano mea like ʻole.

ʻIke pH:

Hiki ke hoʻopili ʻia nā waiwai o HPMC e ka pH o ka hopena a i ʻole ka hoʻokumu ʻana. Paʻa maʻamau ma luna o kahi ākea pH ākea.

Paʻa wela:

Manaʻo ʻia ʻo HPMC he biodegradable, hiki ke hoʻohana pono i kekahi mau noi kaiapuni a hoʻomau.

ʻO kēia mau waiwai maʻamau ka HPMC he polymer maʻamau a hoʻohana nui ʻia i nā ʻoihana e like me nā lāʻau lapaʻau, kūkulu hale, meaʻai, mea hoʻonaninani, a me nā mea hou aku. ʻO kona hiki ke hoʻololi i nā waiwai rheological a me ka hana o nā formulations e kōkua i kona hoʻohana ākea.
