Polyethylene glycol (PEG)

1. Polyethylene glycol series cov khoom siv tuaj yeem siv rau hauv cov tshuaj.Polyethylene glycol nrog qis tus txheeb ze molecular hnyav tuaj yeem siv los ua cov kuab tshuaj, co-solvent, O / W emulsifier thiab stabilizer, siv los ua cov cement suspensions, emulsions, txhaj tshuaj, thiab lwm yam, thiab kuj siv los ua dej-soluble ointment matrix thiab suppository matrix, khoom waxy polyethylene glycol nrog cov txheeb ze molecular hnyav feem ntau yog siv los ua kom cov viscosity thiab solidification ntawm tsawg molecular hnyav kua PEG, raws li zoo raws li them rau lwm yam tshuaj;Rau cov tshuaj uas tsis yooj yim soluble nyob rau hauv dej, cov khoom no yuav siv tau raws li ib tug neeg nqa khoom ntawm dispersant kom tiav lub hom phiaj ntawm cov khoom dispersion, PEG4000, PEG6000 yog ib tug zoo txheej cov ntaub ntawv, hydrophilic polishing cov ntaub ntawv, zaj duab xis thiab capsule cov ntaub ntawv, plasticizers, lubricants thiab poob tshuaj matrix, rau kev npaj cov ntsiav tshuaj, tshuaj, tshuaj ntsiav, microencapsulations, thiab lwm yam.

2. PEG4000 thiab PEG6000 yog siv los ua excipients nyob rau hauv kev lag luam kws tshuaj rau kev npaj suppositories thiab tshuaj pleev;Nws yog siv los ua tus neeg sawv cev hauv kev lag luam ntawv txhawm rau ua kom cov ntawv ci thiab du;Nyob rau hauv kev lag luam roj hmab, raws li ib tug additive, nws tsub kom lub lubricaity thiab plasticity ntawm cov khoom roj hmab, txo hwj chim noj thaum lub sij hawm ua, thiab prolongs lub neej kev pab cuam ntawm cov khoom roj hmab.

3. Polyethylene glycol series khoom siv tau los ua raw khoom rau ester surfactants.

4. PEG-200 tuaj yeem siv los ua qhov nruab nrab rau cov organic synthesis thiab cov khoom siv hluav taws xob uas muaj cov khoom siv hluav taws xob siab, thiab siv los ua cov khoom siv moisturizer, inorganic ntsev solubilizer, thiab viscosity adjuster hauv kev lag luam tshuaj txhua hnub;Siv ua softener thiab antistatic tus neeg sawv cev hauv kev lag luam textile;Nws yog siv los ua tus neeg sawv cev ntub dej hauv kev lag luam ntawv thiab tshuaj tua kab.

5. PEG-400, PEG-600, PEG-800 yog siv los ua substrates rau tshuaj thiab tshuaj pleev ib ce, lubricants thiab wetting agents rau roj hmab kev lag luam thiab textile kev lag luam.PEG-600 yog ntxiv rau cov electrolyte hauv kev lag luam hlau txhawm rau txhim kho kev sib tsoo thiab txhim kho cov luster ntawm cov hlau nto.

6. PEG-1000, PEG-1500 yog siv los ua matrix lossis lubricant thiab softener hauv kev lag luam tshuaj, textile thiab cosmetic;Siv los ua ib qho dispersant hauv kev lag luam txheej;Txhim kho cov dej dispersibility thiab hloov tau yooj yim ntawm cov resin, qhov ntau npaum li cas yog 20 ~ 30%;Tus cwj mem tuaj yeem txhim kho cov dej solubility ntawm cov xim thiab txo nws cov volatility, uas yog tshwj xeeb tshaj yog haum rau hauv daim ntawv siv quav ciab thiab cov ntaub ntawv tus cwj mem, thiab tseem tuaj yeem siv rau hauv cov cwj mem cwj mem los kho tus cwj mem viscosity;Nyob rau hauv kev lag luam roj hmab raws li ib tug dispersant, txhawb vulcanization, siv raws li ib tug dispersant rau carbon dub muab tub lim.

7. PEG-2000, PEG-3000 yog siv los ua cov khoom siv hlau ua hlau, hlau hlau kos duab, stamping los yog ua cov roj nplua nyeem thiab txiav cov kua dej, sib tsoo txias lubricants thiab polishes, welding agents, thiab lwm yam .;Nws yog siv los ua cov roj nplua nyeem hauv daim ntawv kev lag luam, thiab lwm yam, thiab tseem siv los ua cov nplaum kub yaj kom ua kom muaj peev xwm rov qab sai.

8. PEG-4000 thiab PEG-6000 yog siv los ua substrates hauv kev lag luam tshuaj thiab tshuaj pleev ib ce, thiab ua lub luag haujlwm ntawm kev kho cov viscosity thiab melting point;Nws yog siv los ua cov roj nplua nyeem thiab cov dej txias hauv kev lag luam roj hmab thiab hlau, thiab ua ib qho dispersant thiab emulsifier hauv kev tsim cov tshuaj tua kab thiab pigments;Siv los ua tus neeg sawv cev antistatic, lubricant, thiab lwm yam hauv kev lag luam textile.

9. PEG8000 yog siv los ua matrix hauv kev lag luam tshuaj thiab tshuaj pleev ib ce los kho cov viscosity thiab melting point;Nws yog siv los ua cov roj nplua nyeem thiab cov dej txias hauv kev lag luam roj hmab thiab hlau, thiab ua ib qho dispersant thiab emulsifier hauv kev tsim cov tshuaj tua kab thiab pigments;Siv los ua tus neeg sawv cev antistatic, lubricant, thiab lwm yam hauv kev lag luam textile.
