Poly(propylene glycol) CAS:25322-69-4
I le avea ai o se tuufaatasiga lauiloa, polypropylene glycol Cas25322-69-4 ua avea ma mea taua i le gaosiga o le tele o tagata faatau ma oloa gaosi oloa.O ona uiga autu e aofia ai le mautu lelei o le vevela, maualalo le oona ma le fetaui lelei o vailaʻau.O nei faʻaaliga e faʻapitoa ai mo le tele o faʻaoga, faʻamautinoa le faʻatuatuaina o le faʻatinoga ma faʻamanuiaga sili.
O se tasi o faʻamanuiaga autu o le polypropylene glycol Cas25322-69-4 o lona faʻamautuina lelei o le vevela.O le mea lea e fetaui lelei mo talosaga e manaʻomia ai le faʻaalia i le maualuga o le vevela, e pei o suauʻu hydraulic, lubricants ma sua vevela.Faatasi ai ma lona gafatia e faʻatumauina le faʻatinoga faifaipea i lalo o tulaga ogaoga, o lau faʻagasologa e mafai ona sologa lelei ma lelei e aunoa ma le fefe i le faʻaleagaina o le vevela poʻo le faʻaleagaina o galuega.
E le gata i lea, o le maualalo o le oona o le oloa o se isi tulaga taua.E fa'amautinoa ai le saogalemu o le si'osi'omaga o galuega a'o fa'aitiitia le fa'aleagaina o tagata faigaluega.O le mea lea e avea ai ma filifiliga sili mo vaila'au fa'afoma'i ma tausiga fa'aletagata e fa'atatau i le saogalemu o oloa.E le gata i lea, o lona maualalo oona e oʻo atu i iloiloga o le siosiomaga, ma avea ai ma filifiliga sili atu ona gafatia nai lo isi vailaʻau.
O le Polypropylene glycol Cas25322-69-4 o loʻo iai foʻi le fetaui lelei o vailaʻau, e faʻaoga lelei ai mo le faʻaaogaina i ituaiga eseese.E lelei le solubility mo le tele o mea polar ma non-polar, faʻamautinoa le faʻaogaina faigofie i lau gaioiga o loʻo iai.Pe e te manaʻomia se faʻasalalau, faʻasusu susū poʻo se emulsifier, o lenei mea faʻapipiʻi felagolagomai e maua ai iʻuga mataʻina.
E le gata i lea, oa tatou oloa e gaosia i tulaga maualuga o alamanuia, faʻamautinoaina le lelei ma le faʻamaoni.O laʻasaga uma o le gaosiga e mulimulitaʻia se faiga faʻatonutonu lelei, faʻamautinoa o le oloa e te mauaina o le a ausia pe sili atu i ou faʻamoemoega.Matou te fa'amaualuga tele i le tu'uina atu o vaila'au fa'atino e fa'amalieina ai lau fa'agasologa ma saofagā i lou manuia lautele.
I le faʻaiʻuga, o le polypropylene glycol Cas25322-69-4 o se suʻega taʻaloga mo le vailaʻau vailaʻau, e ofoina atu le faʻatinoga sili atu, agavaʻa, ma le faʻamaoni.O lona mautu vevela, maualalo oona ma vailaʻau fesoʻotaʻiga e avea ai ma mea taua i pisinisi eseese.Faatasi ai ma la matou tautinoga i le lelei ma le faamalieina o tagata faatau, matou te faamautinoa atu ia te oe o lau tupe teufaafaigaluega i a matou oloa o le a maua ai ni taunuuga sili ona lelei.Fa'aleleia lau fa'agasologa i aso nei ile Polypropylene Glycol Cas25322-69-4 ma iloa le eseesega e mafai ona faia.
