Polypropylene glycol (PPG)isiri-ionic polymer inowanikwa nering-kuvhura polymerization yepropylene oxide. Iyo ine yakakosha zvivakwa senge inogadziriswa mvura solubility, yakakura viscosity renji, yakasimba makemikari kugadzikana, uye yakaderera toxicity. Zvishandiso zvaro zvinotora maindasitiri mazhinji, anosanganisira makemikari, mishonga, makemikari ezuva nezuva, chikafu, uye kugadzira maindasitiri. PPGs ehuremu hwemamorekuru hwakasiyana (kazhinji kubva pa200 kusvika pamusoro pe10,000) anoratidza misiyano yakakosha yekushanda. Low-molecular-weight PPGs (yakadai sePPG-200 uye 400) inonyanya kunyunguduka mumvura uye inowanzoshandiswa semishonga uye plasticizers. Epakati- uye akakwira-mamorekuru-huremu maPPGs (akadai sePPG-1000 uye 2000) anonyungudika nemafuta kana semi-akasimba uye anonyanya kushandiswa mukumisikidza uye elastomer synthesis. Iyi inotevera ongororo yakadzama yenzvimbo dzayo huru dzekushandisa:
1. Polyurethane (PU) Indasitiri: Imwe yeCore Raw Materials
PPG chinhu chakakosha polyol raw material yekugadzira polyurethane zvinhu. Nekuita neisocyanates (senge MDI neTDI) uye kusanganisa nemaketani ekuwedzera, inogona kuburitsa mhando dzakasiyana dzezvigadzirwa zvePU, zvichifukidza huwandu hwakazara hweakapfava kune akaomesesa foam mapoka:
Polyurethane elastomers: PPG-1000-4000 inowanzoshandiswa mukugadzirira thermoplastic polyurethane (TPU) uye yakakandwa polyurethane elastomers (CPU). Aya elastomers anoshandiswa mumasoles eshangu (senge cushioning midsoles yeshangu dzemumhanyi), zvisimbiso zvemakanika, mabhandi ekutakurisa, uye makateta ekurapa (ane biocompatibility yakanakisa). Ivo vanopa abrasion kuramba, kuramba kubvarura, uye kuchinjika.
Polyurethane coatings/adhesives: PPG inonatsiridza kuchinjika, kuramba mvura, uye kunamira kwemachira uye inoshandiswa mumotokari pendi yeOEM, pendi yeindasitiri inorwisa ngura, uye machira emapuranga. Mune zvinonamira, inosimudzira kusimba kwechisungo uye kuramba kwemamiriro ekunze, ichiita kuti ive yakakodzera kusungirira simbi, mapurasitiki, matehwe, uye zvimwe zvinhu.
2. Daily Chemicals uye Personal Care: Functional Additives
PPG, nekuda kwehunyoro hwayo, emulsifying zvivakwa, uye inonyorovesa zvivakwa, inoshandiswa zvakanyanya mukuchengetedza ganda, zvizorwa, detergents, uye zvimwe zvigadzirwa. Zvigadzirwa zvakasiyana zvehuremu zvine mabasa akasiyana:
Emulsifiers uye Solubilizers: Medium molecular weight PPG (yakadai sePPG-600 nePPG-1000) inowanzosanganiswa nemafuta acids uye esters se nonionic emulsifier mumakirimu, lotions, shampoos, uye mamwe magadzirirwo, kugadzikana kwemafuta-mvura masisitimu uye kudzivirira kuparadzana. Yakaderera molecular uremu PPG (yakadai sePPG-200) inogona kushandiswa sesolubilizer, ichibatsira kunyungudutsa mafuta-anonyungudika zvinhu zvakadai sezvinonhuhwirira uye akakosha maoiri mukuumbwa kwemvura.
Moisturizers uye Emollients: PPG-400 uye PPG-600 inopa ine mwero yekunyorovesa maitiro uye inozorodza, isina-mafuta kunzwa. Vanogona kutsiva imwe glycerin mune toner uye serums, kuvandudza chigadzirwa glide. Mune maconditioners, anogona kuderedza static magetsi uye kuwedzera bvudzi kutsetseka. Kuchenesa Zvigadzirwa Zvinowedzera: Mukugeza gels uye sipo dzemaoko, PPG inogona kugadzirisa fomula viscosity, kuwedzera kugadzikana kwefuro, uye kuderedza kushatirwa kwevanoshandisa surfactants. Mumushonga wemazino, unoshanda sehumectant uye thickener, kudzivirira paste kubva pakuoma uye kuputika.
3. Pharmaceutical and Medical Applications: High-Safety Applications
Nekuda kwekuderera kwayo muchetura uye yakanakisa biocompatibility (inoenderana neUSP, EP, uye mamwe maitiro emishonga), PPG inoshandiswa zvakanyanya mukugadzira mishonga uye zvigadzirwa zvekurapa.
Zvinodhaka Zvinotakura uye zvinonyungudutsa: Yakaderera mamorekuru huremu PPG (yakadai sePPG-200 uye PPG-400) inonyungudutsa yakanakisa yemishonga isinganyungudika uye inogona kushandiswa mumuromo nekumisikidza nemajekiseni (inoda kuchena kwakasimba kudzora uye kubviswa kwekutsvaga tsvina), kuvandudza kunyungudika kwezvinodhaka uye bioavailability. Uyezve, PPG inogona kushandiswa seyo suppository base yekuvandudza kuburitswa kwezvinodhaka.
Medical Material Kugadziridzwa: Muzvokurapa zve polyurethane zvinhu (zvakadai semidziyo yeropa, mavharuvhu emwoyo, uye weti catheter), PPG inogona kugadzirisa hydrophilicity uye biocompatibility yechinhu, ichidzikisa immune system yemuviri uku ichivandudzawo kuchinjika kwechinhu uye kusagadzikana kweropa. Pharmaceutical Excipients: PPG inogona kushandiswa sechikamu chechikamu muzvizoro uye makirimu kuti iwedzere kupinda kwezvinodhaka kuburikidza neganda uye inokodzera mishonga yemusoro (senge antibacterial uye steroid mafuta ekuzora).
4. Industrial Lubrication uye Machinery: High-Performance Lubricants
PPG inopa yakanakisa lubricity, anti-kupfeka zvivakwa, uye yakakwirira uye yakaderera-tembiricha kuramba. Iyo zvakare ine kuenderana kwakasimba nemamineral oiri uye zvinowedzera, zvichiita kuti ive yakakosha zvinhu zvekugadzira mafuta ekugadzira.
Hydraulic uye Gear Mafuta: Epakati- uye akakwira-mamorekuru-huremu maPPGs (akadai sePPG-1000 uye 2000) anogona kushandiswa kugadzira anti-kupfeka hydraulic zvinwiwa zvakakodzerwa ne-high-pressure hydraulic system mumakina ekuvaka uye maturusi emuchina. Ivo vanochengeta yakanakisa fluidity kunyangwe pakudziya kwakadzika. Mumafuta egiya, anowedzera anti-seizure uye anti-kupfeka zvivakwa, achiwedzera hupenyu hwegiya.
Metalworking Fluids: PPG inogona kushandiswa sechinhu chinowedzera mukugadzira simbi uye kukuya zvinwiwa, kupa mafuta, kutonhora, uye kudzivirira ngura, kuderedza kupfeka kwezvishandiso uye kugadzirisa machining. Iyo zvakare ine biodegradable (mamwe maPPG akagadziridzwa anosangana nezvinodiwa zvezvakatipoteredza zvekucheka zvinwiwa). Specialty Lubricant: Mafuta anoshandiswa mukupisa kwepamusoro-soro, kudzvanya-kudzvanya, kana hunyanzvi midhiya (senge acidic uye alkaline nharaunda), senge midziyo yemuchadenga nemapombi emakemikari nemavharuvhu, anogona kutsiva echinyakare mineral oiri uye kugadzirisa kuvimbika kwemidziyo.
5. Kugadziriswa Kwezvokudya: Zvokudya-Grade Additives
Chikafu-giredhi PPG (FDA-inoenderana) inonyanya kushandiswa emulsification, defoaming, uye moisturizing mukugadzira chikafu:
Emulsification uye Kudzikamisa: Muzvigadzirwa zvemukaka (senge aizikirimu nekrimu) uye zvinhu zvakabikwa (senge makeke nechingwa), PPG inoita senge emulsifier kudzivirira kupatsanurwa kweoiri uye kunatsiridza kuumbwa kwechigadzirwa kufanana uye kuravira. Muzvinwiwa, inodzikamisa zvinonaka uye pigment kudzivirira kuparadzana.
Defoamer: Mukuita kwekuvirisa kwechikafu (senge doro uye soy sosi kubikwa) uye kugadzira muto, PPG inoita senge defoamer kudzvanya kupupa uye kunatsiridza kugadzirwa kwakanaka pasina kukanganisa kunaka.
Humectant: Mumakeke uye zvihwitsi, PPG inoita seyakanyorovesa kudzivirira kuomesa nekutsemuka, kuwedzera hupenyu hwesherufu.
6. Dzimwe Nzvimbo: Kushanda Kugadziriswa uye Kubatsira Zvikumbiro
Coatings uye Inks: Mukuwedzera kune polyurethane coatings, PPG inogona kushandiswa sechigadziriso chealkyd uye epoxy resins, kuvandudza kuchinjika kwavo, kuenzana, uye kuramba mvura. Mune ingi, inogona kugadzirisa viscosity uye kuwedzera kudhinda (semuenzaniso, offset uye gravure ingi).
Textile Auxiliaries: Inoshandiswa senge antistatic kupera uye kupfava kwemachira, inoderedza static kuvaka uye inosimudzira kupfava. Mukudhaya uye kupedzisa, inogona kushandiswa sechinhu chinoyeresa kuvandudza kupararira kwedhayi uye kuwedzera kudhaya kufanana.
Defoamers uye Demulsifiers: Mukugadzirwa kwemakemikari (semuenzaniso, kugadzira mapepa uye kurapwa kwemvura yetsvina), PPG inogona kushandiswa sedefoamer kudzvinyirira kupupa panguva yekugadzira. Mukugadzirwa kweoiri, inogona kushandiswa sedemulsifier kubatsira kupatsanura mafuta asina kuchena kubva mumvura, nekudaro ichiwedzera kudzoreredza mafuta. Mapoinzi Akakosha Ekushandisa: Kushandiswa kwePPG kunoda kunyatsotariswa kwehuremu hwemamorekuru (semuenzaniso, huremu hwemamorekuru hunotarisa pane zvinonyungudutsa uye kunyorova, nepo huremu hwepakati uye hwepamusoro hwemamorekuru hunotarisa pane emulsification uye lubrication) uye kuchena giredhi (yakakwirira-kuchena zvigadzirwa zvinofarirwa mumaindasitiri ezvekudya nemishonga, nepo mamakisi akajairwa achigona kusarudzwa zvichienderana nezvido zveindasitiri). Mamwe maapplication anodawo kugadziridzwa (semuenzaniso, kubatanidza kana kubatanidza-kubatanidza) kuti uwedzere kuita (semuenzaniso, kuwedzera kupisa kwekupisa uye kunonoka kwemoto). Nekuwedzera kudiwa kwekuchengetedzwa kwezvakatipoteredza uye kushanda kwakanyanya, nzvimbo dzekushandisa dzePPG yakagadziridzwa (semuenzaniso, bio-based PPG uye biodegradable PPG) iri kuwedzera.
