Hydroxypropyl starch etera-HPS

ʻO ka hydroxypropyl starch ether (HPS) he mea hoʻololi kemika i hoʻololi ʻia i ka starch derivative i loaʻa ka hoʻohana nui ʻana i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa. Loaʻa ʻia kēia pūhui ma ka hana ʻana i ka starch me ka propylene oxide, e alakaʻi ana i ka hoʻololi ʻana o nā pūʻulu hydroxyl i loko o ka mole starch me nā hui hydroxypropyl. Hōʻike ka huahana i hoʻonui ʻia i ka hoʻoheheʻe wai, kūpaʻa, viscosity, a me nā waiwai hana kiʻiʻoniʻoni i hoʻohālikelike ʻia me ka starch maoli.

1. Hoʻolālā a me nā waiwai:

Loaʻa i ka hydroxypropyl starch ether kahi ʻano paʻakikī ma muli o ka hoʻololi ʻana o ka molela starch. ʻO ka starch he polysaccharide i haku ʻia me nā ʻāpana glucose i hoʻopili ʻia e nā paʻa glycosidic. ʻO ke kaʻina hana hydroxypropylation ka hoʻololi ʻana i nā pūʻulu hydroxyl (-OH) i loko o ka molekele starch me nā hui hydroxypropyl (-OCH2CHOHCH3). Hoʻololi kēia hoʻololi i nā waiwai kino a me nā kemika o ka starch, e hāʻawi ana i nā ʻano maikaʻi.

ʻO ke kiʻekiʻe o ka hoʻololi (DS) kahi mea koʻikoʻi e hoʻoholo ai i ka nui o ka hydroxypropylation. Hōʻike ia i ka helu awelika o nā pūʻulu hydroxypropyl i hoʻopili ʻia i kēlā me kēia ʻāpana glucose i loko o ka moleki starch. Hōʻike nā koina DS kiʻekiʻe i kahi kiʻekiʻe o ka hoʻololi ʻana, e alakaʻi ana i nā loli nui i nā waiwai starch.

2.Hydroxypropyl starch ether hōʻike i kekahi mau waiwai makemake:

Hiki i ka wai: Hōʻike ka HPS i ka hoʻonui ʻana i ka solubility i ka wai i hoʻohālikelike ʻia me ka starch maoli, no laila kūpono ia no nā noi like ʻole kahi e koi ʻia ai ka hoʻokumu ʻana i ka wai.

Viscosity: ʻO ka loaʻa ʻana o nā pūʻulu hydroxypropyl e hāʻawi i ka viscosity i hoʻonui ʻia i nā hoʻonā HPS, ʻoi aku ka maikaʻi i nā noi mānoanoa e like me nā adhesives, nā uhi a me nā mea hana.

Hiki ke hana kiʻiʻoniʻoni: Hiki i ka HPS ke hana i nā kiʻiʻoniʻoni maʻalahi a maopopo i ka maloʻo ʻana, e hāʻawi ana i nā waiwai pale a me ka pale ʻana i ka wai. He waiwai kēia waiwai i nā noi e like me nā kiʻiʻoniʻoni edible, nā uhi, a me nā mea hoʻopili.

Paʻa: Hōʻike ka hydroxypropyl starch ether i ka hoʻomaikaʻi ʻana i ke kūpaʻa kūʻē i ka wela, ka shear, a me ka hoʻohaʻahaʻa kemika i hoʻohālikelike ʻia me ka starch maoli, e hoʻonui ana i kāna pono i nā kaiapuni a me nā kaʻina hana.

Hoʻohālikelike: Ua kūpono ʻo HPS me kahi ākea o nā mea hoʻohui, polymers, a me nā mea hoʻohui, e hiki ai ke hoʻohana ʻia i loko o nā ʻano me nā haku mele paʻakikī.

3. Nā noi:

Loaʻa ka hydroxypropyl starch ether i nā noi nui ma waena o nā ʻoihana like ʻole ma muli o kāna mau waiwai. ʻO kekahi o nā noi nui:

Mea Hana Hana: Hoʻohana ʻia ʻo HPS ma ke ʻano he rheology modifier, thickener, a me ka mea mālama paʻa wai i nā huahana sima, plasters gypsum, tile adhesives, a me nā morta. Hoʻonui ia i ka hana, adhesion, a me nā waiwai mechanical o kēia mau mea.

Meaʻai a me nā mea inu: I ka ʻoihana meaʻai, hoʻohana ʻia ʻo HPS ma ke ʻano he stabilizer, thickener, a me texturizer i nā huahana e like me ka soup, sauces, dairy desserts, a me nā mea confectionery. Hoʻonui ia i ka ʻoluʻolu o ka waha, ka paʻa ʻole, a me ka paʻa ʻole o ka ʻono a me ka ʻala.

ʻO nā lāʻau lapaʻau: Hoʻohana ʻia ka hydroxypropyl starch ether i loko o nā hana lāʻau lapaʻau ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka mea hoʻokuʻu i hoʻokuʻu ʻia i ka hana papa. Hoʻomaʻamaʻa ia i ka hoʻopili ʻana i ka papa, paipai i ka hoʻokuʻu ʻana i ka lāʻau lapaʻau like ʻole, a hoʻomaikaʻi i ka mālama ʻana i ka maʻi.

Nā huahana mālama pilikino: Hoʻokomo ʻia ʻo HPS i loko o nā mea hoʻonaninani, nā hale lole, a me nā huahana mālama pilikino ma ke ʻano he mānoanoa, emulsifier, a me ke kiʻiʻoniʻoni mua. Hoʻonui ia i ke ʻano o ka huahana, kūpaʻa, a me nā hiʻohiʻona sensory i loko o nā hana e like me nā creams, lotions, a me nā huahana mālama lauoho.

Pepa a me nā Textiles: Ma ka ʻoihana pepa, hoʻohana ʻia ʻo HPS ma ke ʻano he mea hoʻomāhuahua i ka ʻili, ka mea hoʻopili uhi, a me ka hoʻoikaika ikaika e hoʻomaikaʻi i ka maikaʻi o ka pepa, hiki ke paʻi ʻia, a me nā waiwai ikaika. I loko o nā textiles, hoʻohana ʻia ia ma ke ʻano he mea nui e hāʻawi i ka paʻakikī a me ka maʻalahi i nā lole.

4. Pono:

ʻO ka hoʻohana ʻana i ka hydroxypropyl starch ether e hāʻawi i nā pono he nui i nā mea hana, nā mea hana, a me nā mea hoʻohana hope:

Hoʻomaikaʻi i ka hana: Hoʻonui ka HPS i ka hana o nā huahana like ʻole ma o ka hāʻawi ʻana i nā waiwai i makemake ʻia e like me ka mana viscosity, kūpaʻa, adhesion, a me ka hana kiʻiʻoniʻoni.

Versatility: ʻO kona kūlike me nā mea ʻē aʻe a me nā mea hana e hiki ai i nā ʻano hana like ʻole ma waena o nā ʻoihana he nui, hiki ke hoʻomohala i nā huahana hou.

Uku-Kumu: ʻOiai ʻo kona mau waiwai i hoʻonui ʻia, hāʻawi ʻo HPS i nā hoʻonā kumu kūʻai i hoʻohālikelike ʻia me nā mea hoʻohui a i ʻole nā ​​​​mea hoʻohui ʻē aʻe, e hāʻawi ana i ka mālama kālā holoʻokoʻa i loko o nā formulations.

Hoʻokō hoʻoponopono: Hoʻokō ʻo HPS i nā kūlana hoʻoponopono no ka palekana, ka maikaʻi, a me ka hoʻokō ʻana i ke kaiapuni, e hōʻoia ana i ka hoʻokō ʻana i nā lula pili a me nā kūlana ma nā wahi like ʻole.

Hoʻomau: Loaʻa nā derivatives i hoʻokumu ʻia i ka starch e like me HPS mai nā kumuwaiwai hou, e hoʻolilo iā lākou i mau mea ʻokoʻa e pili ana i ke kaiapuni.

nā mea hoʻohui ʻaila. Hāʻawi hou ko lākou biodegradability i nā hana hoʻomau.

ʻO ka hydroxypropyl starch ether (HPS) he mea maʻalahi a waiwai nui me nā noi like ʻole ma waena o nā ʻoihana mai ke kūkulu ʻana a me ka meaʻai i nā lāʻau lapaʻau a me ka mālama pilikino. ʻO kona mau waiwai kūʻokoʻa, me ka hoʻonui ʻia o ka solubility, viscosity, stability, a me ka hiki ke hana kiʻiʻoniʻoni, e lilo ia i mea koʻikoʻi i nā ʻano hana he nui. Ke hoʻomau nei nā ʻoihana i ka ʻimi ʻana i nā mea hoʻomau a me ka hana kiʻekiʻe, ke manaʻo nei e ulu ka noi no HPS, e alakaʻi ana i nā mea hou a me nā noi i ka wā e hiki mai ana.
