Triethylene Glycol: Xigwitsirisi lexi tirhaka kahle na Xitirhisiwa xo ka xi nga tirhisiwanga xa tikhemikhali xa swikongomelo swo tala
Tinsimu Letikulu ta Xikombelo
Eka bindzu ra tikhemikhali, triethylene glycol i xitofu lexi tirhaka kahle lexi nga n’okisaka swiaki swo hambana-hambana leswi hanyaka, swo tanihi ti- resins, tidayi ni swinun’hweriso. Yitala kutirhisiwa eka vuhumelerisi bya swifunengeto, ti inks, na swinamarheti, leswi nyikaka ku n’oka kahle xikan’we na swivumbeko swo endla filimi. Ku engetela kwalano, triethylene glycol yinga tirhisiwa ku endla swin’wana swa organic compounds, kufana na triethylene glycol ethers na esters, leswi tirhisiwaka ngopfu tani hi ti plasticizers nati surfactants.
Eka bindzu ra mirhi, triethylene glycol yitirhisiwa tani hi solvent na humectant. Yi nga n’okisela swiphemu swo karhi swa mirhi, yi antswisa ku tiya ni ku n’oka ka mirhi, ngopfu-ngopfu eku lunghiseleleni ka switlhavelo ni mati ya nomu. Ku engetela kwalano, triethylene glycol yinga tirhisiwa ku lawula mpimo wa ku humesiwa ka mirhi, ku antswisa bioavailability ya yona.
Eka bindzu ra swiambalo, triethylene glycol yitirhisiwa tani hi humectant xikan’we naku olovisa. Swinga engetela ku olova na anti-static properties ya ti fibre, ku antswisa ku titwa ka mavoko xikan’we na matirhelo ya processing ya malapi. Triethylene glycol yitlhela yitirhisiwa eka post-treatment ya swiambalo kuva yi ndlandlamuxa ku tiya ka swona eka ku onhaka xikan’we naku lwisana na swirhumbana.
Eka bindzu ra electronics, triethylene glycol yitirhisiwa tani hi xibasisi na solvent. Yi nga susa kahle masalela na thyaka ehenhla ka swiphemu swa elektroniki, ku tiyisisa ku basa na matirhelo ya swona. Triethylene glycol yitlhela yitirhisiwa eka vumaki bya ti semiconductor ku basisa swiphemu swa wafer, ku susa masalela ya photoresist na thyaka rin’wana.
Eka ku basisiwa ka mati, triethylene glycol yitirhisiwa tani hi antifreeze na corrosion inhibitor. Swinga hunguta nhlayo ya mati yo titimela, swi sivela coolant ku titimela eka mahiselo yale hansi, naswona swihunguta ku bola ka switirhisiwa. Triethylene glycol-based antifreeze yitirhisiwa ngopfu eka tisisiteme ta mati yo kufumeta ya ti indasitiri na switolwa swa mimovha.
Hambi leswi yi tirhisiwaka hi tindlela to hambana hambana, triethylene glycol yi na viscous naswona yi na hygroscopic, naswona ku tirhisiwa na ku hlayisiwa ka yona swi lava magoza yo tika ya vuhlayiseki. Triethylene glycol yi tswonga ndzhongho hiku olova eka tindzhawu leti kufumelaka, hikokwalaho yifanele ku hlayisiwa eka xigwitsirisi lexi pfaleriweke. Ku engetela kwalano, swintshuxo swa triethylene glycol swina viscous nyana, naswona switirhisiwa leswi faneleke swo sirhelela swifanele ku ambariwa loko switirhisiwa ku papalata ku khumbana na nhlonge na mahlo. Eka vuhumelerisi bya ti indasitiri, kutirhisiwa ka triethylene glycol hi ntolovelo swihumelela eka tisisiteme leti pfalekeke kuva kuhungutiwa ku onhiwa ka mbango.

Hi ku komisa
Hiku komisa, triethylene glycol, tani hi organic chemical raw material ya nkoka na solvent, yi tlanga xiave xa nkoka eka ti indasitiri to tala. A swi ndlandlamuxi ntsena matirhelo ya swikumiwa na khwalithi kambe swi tlhela swi seketela nhluvukiso wa indasitiri ya manguva lawa. Hi nhluvuko wa thekinoloji lowu yaka emahlweni, ntshembo wa ku tirhisiwa ka triethylene glycol wu ta anama swinene.
