Usetyenziso lwe-PG

1. Imathiriyeli ekrwada yeresin, iiplasticizers, surfactants, emulsifiers, ne emulsifiers nazo zinokusetyenziswa njenge antifreeze kunye nezinto ezithwala ubushushu.
2. Kwisigaba segesi sechromatography isisombululo esisisigxina, i-solvent, i-antifreeze, i-plasticizer kunye ne-dehydration agent.
3.Isombululi semali-mboleko;i-humidizer;i-moisturizer;iyezaantioxidant;i-ejenti yokuphucula izicubu;i-surfactant;isizinzi;ijiyileumlawuli wentlama;emulsifier;i-ejenti yesinongo;i-arhente yokucubungula.I-GB2760 ~ 96 idweliswe njengezongezo zokulungisa ukutya.Isetyenziselwa ikakhulu ukutsalwa kwezinyibilikisi zeentlobo ngeentlobo zeziqholo, iipigments, izigcini, kunye neembotyi zevanila zechecalbook, iinkozo zekofu ezigcadiweyo, kunye neziqholo zendalo.I-ejenti yokuthambisa kunye nethambileyo yeelekese, isonka, inyama yokupakisha, itshizi, njl njl.Ukongeza i-0.006% kubisi lwesoya kunokwenza incasa ingatshintshi ngexesha lokufudumeza.Yenziwe ibe yitofu yokupakisha emhlophe kwaye ecwebezelayo, kwaye ukuqhotsa kuya kwandisa umthamo.
4. Ingulube -glycol iphakathi kwe-benzazole ye-germine.
5. Njenge-solvent, i-preservatives, i-pigments, i-antioxidants kunye nezinye izongezo zokutya okunzima ukuchithwa emanzini njengamanzi achithwa emanzini, kwaye zongezwa ekudleni;ine-hygroscopicity enamandla kwaye inefuthe lokuthambisa kunye neqhwa ekutyeni.imimiselo yelizwe lam ingasetyenziselwa i-pastry, ngokusetyenziswa okuphezulu kwe-3.0g/kg.
6. I-Pateyl glycol yinto ebalulekileyo ekrwada kwi-polyester engaxutywanga, i-epoxy resin, kunye ne-polyurethane resin.Umlinganiselo wale ndawo ubala malunga ne-45% yokusetyenziswa okupheleleyo kwepropylene glycol.Le polyester ingaxutywanga inkulu yokwaleka komphezulu kunye neplastiki ephuculweyo.I-viscosity kunye ne-hygroscopicity ye-propylene glycol inetyhefu kakuhle.Ke ngoko, isetyenziswa kakhulu kumashishini okutya, amayeza kunye nezithambiso njengeearhente zokumanzisa, i-antifreeze, i-lubricants kunye ne-solvents.Kwishishini lokutya, ipropylene glycol kunye ne-fatty acids zisabela ukuvelisa ipropylene glycol fatty acid.I-Chemicalbook isetyenziswa kakhulu njenge-emulsifier yokutya;ipropylene glycol sisinyibilikisi esigqwesileyo se-condiments kunye ne-pigments.I-Pigbolly isoloko isetyenziselwa i-solvent, i-softener, kunye ne-gumin agent yokwenza iintlobo ezahlukeneyo ze-ointment, i-ointment, kunye ne-glycrastasus kwishishini lamachiza.Ngenxa yokuba ipropylene glycol inokunyibilika okulungileyo kunye neentlobo ezahlukeneyo zeziqholo, ikwasetyenziswa njengesinyibilikisi kunye nesithambisi kwizinto zokuthambisa.I-Pigbolly ikwasetyenziswa njengesinyibilikisi kwi-ejenti zokufuma kwecuba, izinto zokuthintela ukungunda, izixhobo zokulungisa ukutya okuthambisa i-oyile kunye ne-inki yokumakisha ukutya.Isisombululo se-hydraulic sepropylene glycol yi-antifreeze esebenzayo.
7. Njengomntu ophethe amayeza, i-agent ye-pharmaceutical agent.Ingasetyenziselwa njenge-moisturizer kwi-cosmetics, i-softeners, i-solvents, njl njl. Imboni yecuba ingasetyenziswa njengomsi, i-cuba moisturizers, i-preservatives, njl njl. ukutya anti -adhesives, etc. Ingasetyenziselwa ukuvelisa intlaka ipolyester ezingaxutywanga, kwakunye plasticizers, arhente dehydrated, surfactants, amayeza okunyanga, izibophelelo, njl. amanye amashishini
8. Ukususwa kweAviation, iarhente ekhenkcezisiweyo kunye nesikhenkcezisi, ukutya kunye neziqholo, izinto zokuthambisa kunye neemveliso zempilo yomntu, ukuhanjiswa kobushushu, ihydraulic kunye nebrake fluid, ipeyinti kunye neengubo, ukutya kwesilwanyana / ukutya kwezilwanyana, iziyobisi, ipolyurethane, ipolyurethane, ipolyurethane, ipolyurethane. , i-polyurethane, i-polyurethane, i-polyurethane, i-polyurethane, i-resin ye-polyester engafakwanga.
9. I-solvent, i-organic synthesis, i-antifreeze, i-plasticizer, i-sterilizer.Imigangatho yohlalutyo lwekhromatografi yegesi.I-chromatography yegesi esisigxina (ubushushu obuphezulu be-150 ° C, i-solvent yi-chloroform), uhlalutyo olulodwa utywala, i-ester kunye ne-ketone, njl.
