Polypropylene glycol (PPG)he polymer non-ionic i loaʻa ma o ka polymerization puka apo o propylene oxide. Loaʻa iā ia nā waiwai koʻikoʻi e like me ka hiki ke hoʻololi ʻia i ka wai, kahi ākea viscosity ākea, paʻa kemika ikaika, a me ka haʻahaʻa haʻahaʻa. ʻO kāna mau noi e pili ana i nā ʻoihana he nui, me nā kemika, nā lāʻau lapaʻau, nā kemika o kēlā me kēia lā, nā meaʻai, a me nā hana ʻoihana. ʻO nā PPG o nā kaumaha molekala like ʻole (maʻamau mai 200 a ʻoi aku ma mua o 10,000) hōʻike i nā ʻokoʻa hana koʻikoʻi. ʻO nā PPG haʻahaʻa-molecular-kaumaha (e like me PPG-200 a me 400) ʻoi aku ka maʻalahi o ka wai a hoʻohana mau ʻia e like me nā mea hoʻoheheʻe a me nā plasticizer. ʻO nā PPG maʻamau a me ka nui-molecular-weight (e like me PPG-1000 a me 2000) ʻoi aku ka ʻaila-soluble a i ʻole semi-solid a hoʻohana nui ʻia i ka emulsification a me ka elastomer synthesis. ʻO kēia ka ʻike kikoʻī o kāna mau wahi noi nui:
1. ʻOihana Polyurethane (PU): ʻO kekahi o nā mea waiwai kumu
ʻO ka PPG kahi kumu polyol maka no ka hana ʻana i nā mea polyurethane. Ma ka pane ʻana me nā isocyanates (e like me MDI a me TDI) a me ka hui pū ʻana me nā mea hoʻonui kaulahao, hiki iā ia ke hana i nā ʻano huahana PU like ʻole, e uhi ana i ka piha piha o nā ʻāpana palupalu palupalu a paʻa.
Polyurethane elastomers: PPG-1000-4000 ka mea maʻamau i ka hoʻomākaukau ʻana i ka polyurethane thermoplastic (TPU) a me ka hoʻolei ʻana i ka polyurethane elastomers (CPU). Hoʻohana ʻia kēia mau elastomers i nā kapuaʻi kāmaʻa (e like me ka cushioning midsoles no nā kāmaʻa haʻuki), nā sila mechanical, nā kāʻei conveyor, a me nā catheters olakino (me ka biocompatibility maikaʻi loa). Hāʻawi lākou i ke kūpaʻa abrasion, ka waimaka, a me ka maʻalahi.
Polyurethane coatings / adhesives: PPG hoʻomaikaʻi i ka maʻalahi, ka pale ʻana i ka wai, a me ka hoʻopili ʻana o nā uhi a hoʻohana ʻia i nā pena OEM automotive, nā pena anti-corrosion ʻoihana, a me nā uhi lāʻau. I loko o nā adhesives, hoʻonui ia i ka ikaika paʻa a me ke kū'ē i ka wā, kūpono ia no ka hoʻopaʻa ʻana i nā metala, plastics, ʻili, a me nā mea ʻē aʻe.
2. Nā Kemika o kēlā me kēia lā a me ka mālama pilikino: Nā mea hoʻohui hana
PPG, ma muli o kona akahai, emulsifying waiwai, a me moisturizing waiwai, ua hoʻohana nui ia i ka skincare, cosmetics, detergents, a me na huahana. Loaʻa i nā huahana kaumaha molecular nā kuleana ʻokoʻa:
Emulsifiers a me Solubilizers: Medium molecular weight PPG (e like me PPG-600 a me PPG-1000) ua hui pinepine ia me nā momona momona a me nā esters ma ke ʻano he emulsifier nonionic i loko o nā creams, lotions, shampoos, a me nā ʻano hana ʻē aʻe, e hoʻopaʻa i nā ʻōnaehana wai aila a pale i ka kaʻawale. Hiki ke hoʻohana ʻia ʻo PPG molecular haʻahaʻa haʻahaʻa (e like me PPG-200) ma ke ʻano he solubilizer, e kōkua ana i ka hoʻoheheʻe ʻana i nā mea hoʻoheheʻe ʻaila e like me nā mea ʻala a me nā aila pono i loko o nā ʻano wai.
Nā Moisturizers a me nā Emollients: Hāʻawi ʻo PPG-400 a me PPG-600 i kahi hopena moisturizing haʻahaʻa a me kahi manaʻo hōʻoluʻolu, ʻaʻole momona. Hiki iā lākou ke hoʻololi i kekahi glycerin i nā toners a me nā serum, e hoʻomaikaʻi i ka holo ʻana o ka huahana. I loko o nā conditioners, hiki iā lākou ke hōʻemi i ka uila static a hoʻonui i ka lauoho lauoho. Hoʻomaʻemaʻe i nā mea hoʻohui: I loko o nā gels ʻauʻau a me nā kopa lima, hiki i ka PPG ke hoʻoponopono i ka viscosity formula, hoʻonui i ka paʻa o ka foam, a hoʻemi i ka huhū o nā surfactants. I loko o ka toothpaste, hana ia e like me ka humectant a me ka mānoanoa, e pale ana i ka paʻi mai ka maloʻo a me ka pohā.
3. Nā Lapaʻau Lapaʻau a me nā Lapaʻau: Nā noi palekana kiʻekiʻe
Ma muli o ka haʻahaʻa haʻahaʻa a me ka biocompatibility maikaʻi loa (e pili ana me USP, EP, a me nā kūlana lāʻau lapaʻau ʻē aʻe), hoʻohana nui ʻia ʻo PPG i nā hana lāʻau lapaʻau a me nā mea lapaʻau.
ʻO nā mea lawe lāʻau a me nā mea hoʻohenehene: ʻO PPG ke kaumaha haʻahaʻa haʻahaʻa (e like me PPG-200 a me PPG-400) he mea hoʻoheheʻe maikaʻi loa no nā lāʻau hoʻoheheʻe maikaʻi ʻole a hiki ke hoʻohana ʻia i ka hoʻokuʻu waha a me nā injectables (e koi ana i ka hoʻomaʻemaʻe maʻemaʻe a me ka wehe ʻana i nā mea haumia), hoʻomaikaʻi i ka soluble lāʻau a me ka bioavailability. Eia kekahi, hiki ke hoʻohana ʻia ka PPG ma ke ʻano he kumu suppository e hoʻomaikaʻi ai i ka hoʻokuʻu ʻana i ka lāʻau.
Hoʻololi Lapaʻau Lapaʻau: Ma nā mea lapaʻau polyurethane (e like me nā kīʻaha koko artificial, nā puʻuwai puʻuwai, a me nā catheters urinary), hiki i ka PPG ke hoʻoponopono i ka hydrophilicity a me ka biocompatibility o ka mea, e hōʻemi ana i ka pane ʻana o ke kino me ka hoʻomaikaʻi ʻana i ka maʻalahi o ka mea a me ke kūpaʻa koko. Nā Mea Hana Lapaʻau: Hiki ke hoʻohana ʻia ʻo PPG ma ke ʻano he kumu kumu i ka ʻaila a me ka ʻaila e hoʻonui ai i ke komo ʻana o ka lāʻau i loko o ka ʻili a kūpono i nā lāʻau lapaʻau (e like me ka antibacterial a me ka ʻaila steroid).
4. ʻOihana Lubrication a me nā Mīkini: Nā Lubricant Hana Kiʻekiʻe
Hāʻawi ʻo PPG i ka lubricity maikaʻi loa, nā waiwai anti-wear, a me ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Loaʻa iā ia ka hoʻohālikelike ikaika me nā aila mineral a me nā mea hoʻohui, e lilo ia i kumu kumu nui no nā lubricants synthetic.
Hydraulic a me Gear Oils: Hiki ke hoʻohana ʻia nā PPG Medium- a me ke kiʻekiʻe-molecular-weight (e like me PPG-1000 a me 2000) e hana i nā wai hydraulic anti-wear kūpono no nā ʻōnaehana hydraulic kiʻekiʻe i nā mīkini hana a me nā mea hana mīkini. Mālama lākou i ka wai maikaʻi loa ma nā mahana haʻahaʻa. I nā ʻaila ʻaila, hoʻonui lākou i ka anti-seizure a me nā waiwai anti-wear, e hoʻolōʻihi i ke ola o ka mīkini.
ʻO nā wai hana metala: Hiki ke hoʻohana ʻia ka PPG ma ke ʻano he mea hoʻohui i ka hana metala a me ka wili ʻana i nā wai, e hāʻawi ana i ka lubrication, ka hoʻoluʻu, a me ka pale ʻana i ka ʻōpala, e hōʻemi ana i ka ʻaʻahu mea hana a me ka hoʻomaikaʻi ʻana i ka pololei o ka mīkini. Hiki ke biodegradable (ʻo kekahi mau PPG i hoʻololi ʻia e hoʻokō i ka koi no ka ʻoki ʻana i ka wai). Nā Lubricants Kūikawā: ʻO nā lubricants i hoʻohana ʻia i ka wela kiʻekiʻe, ke kaomi kiʻekiʻe, a i ʻole nā mea hoʻolaha kūikawā (e like me ka acidic a me ka alkaline environment), e like me nā lako aerospace a me nā pamu kemika a me nā valves, hiki ke hoʻololi i nā ʻaila mineral kuʻuna a hoʻomaikaʻi i ka hilinaʻi o nā mea hana.
5. Meaʻai Meaʻai: Meaʻai-Grade Additives
Hoʻohana nui ʻia ka PPG meaʻai (FDA-compliant) no ka emulsification, defoaming, a me ka moisturizing i ka hana ʻai.
Emulsification and Stabilization: I nā huahana waiu (e like me ka ice cream a me ka ʻaila) a me nā mea i hoʻomoʻa ʻia (e like me nā keke a me ka berena), hana ʻo PPG ma ke ʻano he emulsifier e pale ai i ka hoʻokaʻawale ʻana o ka aila a hoʻomaikaʻi i ke ʻano o ka huahana a me ka ʻono. I nā mea inu, hoʻokūpaʻa ia i nā ʻono a me nā puaʻa e pale ai i ka kaʻawale.
Defoamer: Ma nā kaʻina hana fermentation meaʻai (e like me ka pia a me ka soy sauce brewing) a me ka hoʻoheheʻe ʻana i ka wai, hana ʻo PPG ma ke ʻano he defoamer e hoʻopaʻa i ka huʻaʻa a hoʻomaikaʻi i ka hana pono me ka ʻole o ka ʻono.
Humectant: I loko o nā pastries a me nā candies, hana ʻo PPG ma ke ʻano he moisturizer e pale ai i ka maloʻo a me ka haki ʻana, e hoʻolōʻihi i ke ola o ka papa.
6. Nā ʻāpana ʻē aʻe: Hoʻololi i ka hana a me nā noi kōkua
ʻO nā uhi a me nā ʻīnika: Ma kahi o ka polyurethane coatings, hiki ke hoʻohana ʻia ka PPG ma ke ʻano he mea hoʻololi no ka alkyd a me ka epoxy resins, e hoʻomaikaʻi i ko lākou maʻalahi, pae, a me ka pale wai. I loko o nā ʻīnika, hiki iā ia ke hoʻololi i ka viscosity a hoʻonui i ka hiki ke paʻi (e laʻa, offset a me gravure inks).
Textile Auxiliaries: Hoʻohana ʻia ma ke ʻano he antistatic hoʻopau a me ka palupalu no nā textiles, e hōʻemi ana i ke kūkulu static a hoʻonui i ka palupalu. I ke kala ʻana a me ka hoʻopau ʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohālikelike e hoʻomaikaʻi i ka hoʻopuehu ʻana o ka wai a hoʻomaikaʻi i ka like ʻana o ke kala.
Nā Defoamers a me nā Demulsifiers: Ma ka hana kemika (e laʻa, ka hana pepa a me ka mālama ʻana i ka wai ʻino), hiki ke hoʻohana ʻia ka PPG ma ke ʻano he defoamer e hoʻopaʻa i ka huʻa i ka wā hana. I ka hana ʻaila, hiki ke hoʻohana ʻia ma ke ʻano he demulsifier e kōkua i ka hoʻokaʻawale ʻana i ka ʻaila mai ka wai, a laila e hoʻonui ai i ka hoʻihoʻi ʻana i ka aila. Nā Manaʻo Koʻikoʻi: Pono ka noi ʻana o PPG e noʻonoʻo pono i ke kaumaha molekala (e laʻa, ke kau nei ke kaumaha molecular haʻahaʻa i nā solvents a me ka moisturizing, ʻoiai ke kau nei ke kaumaha molekala waena a me ke kiʻekiʻe i ka emulsification a me ka lubrication) a me ka maʻemaʻe (ʻoi aku ka maikaʻi o nā huahana maʻemaʻe i ka ʻoihana meaʻai a me nā ʻoihana lāʻau, ʻoiai hiki ke koho ʻia nā māka maʻamau ma muli o nā pono ʻoihana). Pono kekahi mau noi e hoʻololi (e laʻa, grafting a cross-linking) no ka hoʻoikaika ʻana i ka hana (e laʻa, hoʻomaikaʻi i ka pale ʻana i ka wela a me ka hiki ʻana o ke ahi). Me ka hoʻonui ʻana i nā koi no ka mālama ʻana i ke kaiapuni a me ka hana kiʻekiʻe, ke hoʻonui nei nā wahi noi o ka PPG i hoʻololi ʻia (e laʻa, bio-based PPG a me biodegradable PPG).
