ʻO Hydroxyprooppylgallethylcellclolose (HPMC) a me HPMSXYTHYLGYLCALLOUSELLUSLulose (Hec) nā mea hana maʻamau i hoʻohanaʻia ma ka meaʻai, nā hui pūpū a me nāʻoihana lāʻau lapaʻau. Ua loaʻa i kēia mau cedietives i nā derivatives e pili ana i ka nui o nā mea e pono ai ma muli o ko lākou mau wai kai kūʻokoʻa
1.
ʻO HPMC kahi Palmatic Pynthetic i kiʻiʻia mai Cellulose. Hanaʻia e ka chemika me ka hoʻololiʻana i ka cellulose kūlohelohe ma ka hoʻohuiʻana i ka propylene prostlene a me mityl chloride. Heʻano hanaʻo Hec, akā hanaʻia e ka hanaʻana i ka collul kūlohelohe me ka etelene o ka alkali.
2. Mālama:
ʻO ka hpmc a me hec he wai wai-wai a hiki ke hoʻopauʻia i ka wai anuanu. Akā he haʻahaʻa loa ka hopena o ka hec ma mua o ka hpmc. ʻO kēia ka mea eʻoi aku ka maikaʻi o HPMC a hiki ke hoʻohana maʻalahi i nā hana.
3, Viscosity:
ʻO HPMC a hec nā hiʻohiʻona viscosityʻokoʻa ma muli o ko lākou mau mea kanu. Loaʻa iā Hec Molecular kiʻekiʻe kiʻekiʻe a me ka hana denser ma mua o HPMC, e hāʻawi ia i kahi hōʻailona kiʻekiʻe. No laila, hoʻohana pinepineʻiaʻo Hec ma keʻano he shaickener i nāʻano i koiʻia,ʻoiaiʻo HPMC i hoʻohanaʻia ma nāʻano haʻahaʻa haʻahaʻa.
4.ʻO ka hana kiʻi kiʻi:
Loaʻa iā HPMC a me Hec i loaʻa i nā hana kiʻi kiʻi kiʻiʻoniʻoni. Akāʻo HPMC kahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa,ʻo ia ka mea hiki ke hoʻohanaʻia ma nā haʻahaʻa haʻahaʻa. Hana kēia i ka HPMC i kūpono no ka hoʻohanaʻana i nā hana e pono ai e hoʻomaikaʻi wikiwiki i nā manawa maloʻo aʻoi aku ka maikaʻi.
5.ʻO ke kūpaʻa:
Ua paʻaʻo HPMC a me Hec ma lalo o nā kūlana ph a me nā kūlana kiʻekiʻe. Eia nō naʻe,ʻoi aku ka maikaʻi o Hec i nā loli ph ma mua o hpmc. ʻO kēia ke kumu e hoʻohanaʻia aiʻo Hec i nāʻano hana me kahi ph off of 5 a 10
6.
ʻO nā hiʻohiʻona likeʻole o HPMC a me Hec e kūpono iā lākou no nā noi likeʻole. Ua hoʻohana pinepineʻiaʻo Hec ma keʻano he nui o nā mea i loko o ka cosmetic a me nā hana lāʻau lapaʻau. Ua hoʻohanaʻia ia ma keʻano he mea paʻa a me nā mea hana kiʻi kiʻi kiʻi i nā papa hana papa. Hoʻohanaʻiaʻo HPMC ma keʻano he shaickener, stabilizer, a me nā kiʻi kiʻi kiʻi-hana i ka meaʻai, nā lāʻau lapaʻau. Ua hoʻohanaʻia ia ma keʻano he mea kūʻai aku i nā noi o nā meaʻai.
I ka hopena:
ʻO HPMC a me Hecʻo ia nā derivatives cellulose me nā waiwai kūpono kūpono no nā noi likeʻole. Ka hoʻomaopopoʻana i nāʻokoʻa ma waena o kēia mau hoʻohuiʻelua e hiki ke kōkua iāʻoe e koho i ka mea kūpono no kāuʻano. ʻO ka holoʻokoʻa,ʻo HPMC a me ka hec e palekana ai a me nā hoʻohui kūpono e hāʻawi ai i nā pono he nui i ka meaʻai, cosmetic a me nāʻoihana lāʻau lapaʻau.
