I-Triethylene Glycol Butyl Ether

Isinyibilikisi esisebenza kakuhle nesinobuhlobo nokusingqongileyo, esikhuthaza ukuphuculwa komgangatho kumashishini amaninzi

I-Diethylene Glycol Butyl Ether (igama lekhemikhali: i-Diethylene Glycol Monobutyl Ether, igama lesiNgesi: i-Diethylene Glycol Butyl Ether, elifinyeziweyo njenge-DGBE) sisinyibilikisi sendalo esisebenza ngeendlela ezininzi esinamandla okunyibilikisa ngokufanelekileyo, uzinzo oluhle kakhulu, kunye nokhuseleko lokusingqongileyo. Ngeempawu zaso eziphambili zeqondo lokubila eliphezulu, ukuguquguquka okuphantsi, kunye nokunyibilika emanzini nakwioyile, kunye neenzuzo eziluhlaza zetyhefu ephantsi kunye nokukhutshwa kwe-VOC ephantsi, i-DGBE ibe sisongezelelo esiphambili kwiindawo ezahlukeneyo ezifana neengubo, ii-inki, ukucoca kwimizi-mveliso, izixhobo ze-elektroniki, kunye namayeza. Ingathatha indawo ngokuchanekileyo izinyibilikisi zemveli ezinongcoliseko oluphezulu, inceda amashishini ukuba afezekise iinjongo ezininzi zokuphucula ifomula, ukuphucula ukusebenza kakuhle, kunye nokuphucula ukuthobela imithetho.

Ukusebenza okungundoqo: Iingenelo ezininzi, ezichaza indlela entsha yokusebenza kwe-solvent

1. Iqondo lokubila eliphezulu kunye nokuguquguquka okuphantsi, okwenza ulwakhiwo kunye nemveliso zihlale zizinzile

I-DGBE inomlinganiselo wokubila ofikelela kwi-230°C kunye nendawo yokutshayelela evaliweyo engama-78°C, enesantya sokutshayelela esicothayo nesilinganayo. Kwiimeko ezifana nokwakhiwa kobushushu obuphezulu kunye nokubhaka ixesha elide, ingayilungisa ngokufanelekileyo isantya sokomisa kwenkqubo, iphephe iziphene ezifana nexolo le-orenji, imingxunya yepinki, kunye nokumhlophe kwefilimu yokugquma okubangelwa kutshayelela ngokukhawuleza kwezinyibilikisi. Kwangaxeshanye, uyilo lwendawo yokutshayelela ephezulu lunciphisa kakhulu iingozi zokhuseleko ngexesha lokuvelisa nokugcina, luzivumelanisa neemfuno ezahlukeneyo zemveliso enkulu yemizi-mveliso.

2. Amandla okunyibilikisa e-spectrum ebanzi, ukuziqhelanisa okunamandla namanzi kunye neoyile

Ineempawu ezintle kakhulu zokunyibilikisa i-amphiphilic (zombini eziphila emanzini kunye neziphila emanzini), kwaye inokunyibilikisa ngokufanelekileyo izinto ezahlukeneyo ezifana neeresins (i-acrylic resin, i-epoxy resin, i-alkyd resin, njl.njl.), i-nitrocellulose, iigrisi, iidayi, kunye neeoyile zeminerali. Ingaxutywa namanzi nangayiphi na indlela kwaye ihambelane ngokugqibeleleyo nezinyibilikisi ze-organic ezifana ne-ethanol, i-acetone, kunye ne-toluene. Ingaguqulwa ngokuthe ngqo ngaphandle kohlengahlengiso olubalulekileyo kwiifomyula ezikhoyo, nto leyo enciphisa kakhulu iindleko zokuphucula ifomula yeshishini.

3. Uluhlaza, kukhuselekile, kwaye kuyahambelana nemithetho, ngokuhambelana nomkhwa wophuhliso lokhuseleko lokusingqongileyo

Yenziwe kusetyenziswa inkqubo yokwenziwa kwe-green catalytic, imveliso inobumsulwa obuyi-≥99.5% kunye nomxholo wokungcola ophantsi kakhulu. Inobutyhefu obuncinci, kunye nobutyhefu obuncitshiswe ngaphezulu kwe-75% xa kuthelekiswa nezinyibilikisi zemveli (ezifana ne-ethylene glycol ethers) kunye nokukhutshwa kwe-VOC okuncitshiswe nge-90%. Ingahlangabezana ngokulula nemigaqo engqongqo yokusingqongileyo yasekhaya neyangaphandle efana ne-GB, REACH, kunye ne-TSCA, inceda amashishini ukuba agqithe kwimiqobo yorhwebo oluluhlaza.

4. Ukusebenza kakuhle kokudibanisa, ukuphucula uzinzo lwenkqubo

Inomsebenzi olungileyo wokudibanisa nokuzinzisa, onokuphucula ngokufanelekileyo ukuhambelana kweenkqubo ezixutyiweyo, uthintele ukuhluzwa kwefomyula kunye nokuna kwemvula, kwaye wandise ixesha lokugcina imveliso. Xa yongezwa kwiimveliso ezifana nezixhobo zokucoca kunye neengubo, inokuphucula kakhulu amandla okucoca, umgangatho wokwenza ifilimu, kunye nokumelana nemozulu kwenkqubo, ifezekise ukwenziwa ngcono okubanzi kokusebenza kwemveliso.
