Peg200 Polyethylene Glycol 200

Umtya-200:Ingasetyenziselwa njengesixhobo sokudibanisa izinto eziphilayo kunye nomphathi wobushushu kunye neemfuno eziphezulu. Ingasetyenziswa njenge-humectant, isinyibilikisi esongeza ityuwa engaqhelekanga kunye nolawulo lwe-viscosity kumzi mveliso weekhemikhali wemihla ngemihla. Isetyenziswa njengethambisi kunye nearhente ye-antistatic kwishishini lempahla eyolukiweyo; Isetyenziswa njenge-arhente yokumanzisa imveliso kwishishini lephepha kunye nakwimboni yezitshabalalisi. Ukuthambisa okugqwesileyo, ukufuma, ukusasazeka, izinto zokubambelela, iiarhente ze-antistatic kunye nezithambisi; Isicelo: Iikhemikhali zemihla ngemihla: izinto zokuthambisa intlama yamazinyo, iimveliso zokhathalelo lomntu; Ukucocwa kwemizi mveliso: ioyile yokuthambisa yokulungisa isinyithi, ukucoca Ukwenza iphepha kunye nokupakisha: i-plasticizers yokuncamathelisa, iithambisi, kunye ne-emulsifiers yelaphu.
I-Polyethylene glycol kunye ne-polyethylene glycol ene-acid ester isetyenziswa ngokubanzi kushishino lwezithambiso nakwishishini lamayeza. I-Polyethylene glycol inezinto ezininzi ezintle, njengokunyibilika kwamanzi, ukungazinzi, inertia yomzimba, ubulali, ukuthambisa, ukumanzisa, ukuthamba kunye nencasa emnandi. Amaqhekeza obunzima beemolekyuli ezahlukileyo ze-polyethylene glycol anokukhethwa ukuba atshintshe i-viscosity, hygroscopicity kunye ne-microstructure yemveliso. I-Polyethylene glycol (Mnu <2000) enobunzima obuncinci beemolekyuli zilungele ukumanzisa iiarhente kunye nolawulo lokungaguquguquki. Isetyenziselwa ukhilimu, into yokuthambisa, intlama yamazinyo kunye nokucheba cream Ikwasebenza nakwimveliso yeenwele engakhange ihlanjwe, inika iinwele ukubengezela okuqaqambileyo. I-Polyethylene glycol (Mnu 2000) enobunzima obuphezulu beemolekyuli ilungile kwimilebe yomlomo, intonga yokuhambisa, isepha, isepha yokucheba, isiseko kunye nezithambiso Phakathi kweearhente zokucoca, i-polyethylene glycol ikwasetyenziswa njengearhente yokumisa kunye ne-arhente yokuqina. Kushishino lwamayeza, isetyenziswa njenge matrix yeoyile, i-emulsion, ioyile, into yokuthambisa kunye ne-suppository. Intengiso ye-polyethylene glycol (umz. I-polyethylene glycol, i-NF, i-Dow Chemical Co.) ilungele izithambiso. Ukusetyenziswa kwe-methoxypolyethylene glycol kunye ne-polypropylene glycol kuyafana ne-polyethylene glycol.
