I-Triethylene Glycol
Ukuhlolisisa komkhiqizo
I-Triethylene glycol (TEG), enefomula yamakhemikhali C₆H₁₄O₄ kanye nenombolo ye-CAS 112-27-6, yi-polyether compound esebenza kuhle khulu edumileko nge-hygroscopicity yayo, ukuzinza kwamakhemikhali, nokuncibilika okuhlukahlukeneko. Njengombala, ongenaphunga, begodu uketshezi olunamathelako, i-TEG ivele njengesisetjenziswa esithembekileko esiluhlaza nesizo lokucubungula emikhakheni eminengi yamabubulo, iletha ukusebenza okungaguqukiko eensetjenzisweni eziqakathekileko.

Iinsetjenziswa eziqakathekileko ze-Triethylene Glycol
Ibubulo leGesi yemvelo nePhethroliyamu
I-TEG isetjenziswa khulu njenge-ejenti yokuqeda amanzi egesi yemvelo, igesi yephethroliyamu (i-LPG), kanye nemifudlana ye-hydrocarbon. I-hygroscopicity yayo eqinileko yenza bona kususwe umswakama ngendlela ephumelelako ukuhlangabezana namazinga wokuthuthwa kwamapayipi, ukukhandela ukwakheka kwe-hydrate nokugqwala kwemitjhini. I-Triethylene Glycol nayo isetjenziswa eenkambisweni zokwenza igesi ibe mnandi ukwenza ngcono ukusebenza kuhle kokuhlanza.
Ukuhlanganiswa kwamakhemikhali
Njengesisetjenziswa esiphakathi esiqakathekileko, i-Triglycol isebenza njengesisetjenziswa sokukhiqiza:
Ama-polyester resin, ama-polyurethane, kanye namaplastiki
Ama-ether we-glycol (isib., i-triethylene glycol monomethyl ether)
Ama-ester wezithambiso kanye nokugcotshwa okukhethekileko
Ukwakheka kwama-surfactants kanye nama-detergent
Iimboni zemithi nezezithambiso
Isebenza njenge-humectant eentweni zokuzilungisa, imikhiqizo yokutlhogomela isikhumba, kanye nezinto zokutlhogomela umuntu mathupha (isib., amafutha, amakhrimu, amashampu) ukugcina umswakama nokwenza ngcono ukuzwa kwesikhumba.
Isebenza njenge-solvent ne-stabilizer ekwakhiweni kwemithi, kufaka hlangana imithi yomlomo, amakhrimu wendawo, kanye neenhlelo zokulethwa kwemithi.
Isetjenziswa ekudleni okungezelelweko (amagreyidi ahambisana ne-FDA) njengesivikeli somswakama wepahla ebhakiweko kanye nama-confectionery.
I-Triethylenglycol Ezinye Iinsetjenziswa Zebubulo
I-fluid yokudlulisa umtjhiso: Isetjenziswa eenhlelweni zokufuthumala/zokupholisa ezivaliweko ngebanga lendawo yayo ephezulu yokubila nokuzinza kwayo ekutjhiseni.
Ibubulo lezembatho: Isebenza njengesithambiso, isivikeli se-static, nesisiza sokudaya ukwenza ngcono ikhwalithi yetjhila.
I-inki yokugadangisa: Yenza ngcono ukugeleza kwe-inki, ukunamathelana, nokujamelana nomswakama eensetjenzisweni zokugadangisa zezokuthengisa.

Imihlahlandlela yokuPhathwa nokubulunga i-Triethylene Glycol
Ukubulunga: Beka eendaweni ezivaliweko, ezijamelana nokugqwala (i-HDPE, insimbi engagqwali) endaweni epholileko, eyomileko, nengenamoya omuhle. Balekela ukukhanya kwelanga ngqo nokuvezwa emazingeni womtjhiso aphezulu (gcina ngaphasi kwama-30°C).
Ukuphatha: Sebenzisa izinto zokuzivikela ezifaneleko (amagilavu, amagilasi, izambatho zokuzivikela) ukukhandela ukuthintana nesikhumba namehlo. Lokha nakuchitheka, munya ngezinto ezingasebenziko (isib., isihlabathi, i-vermiculite) bese ulahla ngokuya kwemithetho yezebhoduluko yendawo.
Isikhathi se-Triethylene Glycol: iinyanga ezima-24 kusukela ngelanga lokwenziwa lokha nayibekwa ngaphasi kwemibandela ephakanyisiweko.
