Neopentyl Glycol ya Vutengi bya le Henhla (新戊二醇) ya Switirhisiwa swa Tiindasitiri
Tinsimu Letikulu ta Xikombelo
Eka ntirho wa swifunengeto na ti resins, Neopentyl Glycol i raw material ya nkoka eka vuhumelerisi bya saturated polyester resins, unsaturated polyester resins, polyester polyols, na alkyd resins. Ti resins leti titirhisiwa ngopfu eka ti indasitiri ta mimovha, switirhisiwa swale kaya, na switirhisiwa swo khavisa, ngopfu ngopfu eka xiyenge xa powder coatings, laha ku tirhisiwa na nhluvukiso wa Neopenyl Glycol swi vonakaka ngopfu. Xikombiso, hi 2013, kwalomu ka 72% wa Neopenyl Glycol yitirhisiwile ku humelerisa ti polyester resins eka ti powder coatings, leswi sweswi swinga fika eka 89%. Eka ntirho wa ti polyurethanes, Neopenyl Glycol yitirhisiwa ku humelerisa ti polyester polyols, leti tirhisiwaka ngopfu eka ti non-foam polyurethanes. Ti polyurethanes letingana Neopentyl Glycol tina ntshamiseko wa kahle swinene wa hydrolytic, mahiselo yale hansi ya ku cinca ka nghilazi, melting point yale hansi, kutshamiseka kahle ka thermal na UV, xikan’we naku lwisana na ti khemikhali. Swihlawulekisi leswi swi endla leswaku yiva nchumu wa nkoka lowu nga tirhisiwangiki eka vuhumelerisi bya ti polyurethanes ta thermoplastic, swifunengeto swa polyurethane, ti cast elastomers, na swinamarheti. Eka ntirho wa ti plasticizers nati lubricants, Neopentyl Glycol yitirhisiwa ku endla ti plasticizers, leswi nyikaka PVC matirhelo ya kahle swinene ya mahiselo yale hansi, xikan’we naku cinca cinca kale hansi xikan’we naku rhurha. Ku engetela kwalano, ti Neopentyl Glycol diester resins titirhisiwa eka vuhumelerisi bya switolwa swa xiyimo xale henhla swa synthetic. Switolwa leswi, ku engetela eka tindzhawu tale hansi ta freezing, ti high viscosity indices, na tindzhawu tale henhla ta flash, na swona swina ku tiya lokunene ka mahiselo. Eka xiyenge xa mirhi, Neopenyl Glycol yi tlanga xiave xa nkoka eka ku endliwa ka switirhisiwa swa le xikarhi swa mirhi. Xikombiso, eka ku endliwa ka swidlaya-switsongwatsongwana, Neopenyl Glycol yi engetela swinene mbuyelo na ku basa ka swidlaya-switsongwatsongwana hi ku nghenelela eka ku endliwa ka swidlaya-switsongwatsongwana swa nkoka. Ku engetela kwalaho, Neopenyl Glycol yi tlhela yi tlanga xiave xa nkoka eka ku hlanganisiwa ka mirhi yo lwisana na khensa na mirhi ya misiha ya mbilu. Neopentyl Glycol yinga tlhela yitirhisiwa tani hi solvent ya kahle swinene eka ku hambanyisa hiku hlawula ka ti aromatic na cycloalkane hydrocarbons. Swilo leswi humaka eka yona swi tirhisiwa eka swinun’hweriso, swidzidziharisi, swilo leswi sivelaka malangavi, switolwa swa swihaha-mpfhuka, swilo swo endla tipulasitiki, ti-inki, swilo swo pfalela, ni swin’wana, naswona swi tirhisiwa ngopfu eka swifunengeto, mimovha, malapi, swidlaya-switsotswana, tipulasitiki ni le masin’wini ya petroliyamu.

Hi ku komisa
Hiku komisa, Neopentyl Glycol, hi ku tiya ka yona ka kahle swinene ka tikhemikhali na mintirho yotala, yi tlanga xiave xa nkoka eka swifunengeto, ti resins, polyurethanes, ti plasticizers, switolwa, mirhi, na tinsimu tin’wana. Hi nhluvuko lowu yaka emahlweni wa thekinoloji na ku kula loku yaka emahlweni ka xilaveko xa makete, mpimo wa ku tirhisiwa ka Neopenyl Glycol wu ta ya emahlweni wu ndlandlamuxiwa, ngopfungopfu eka tinsimu leti hluvukaka to fana na eneji leyintshwa, tikhemikhali ta rihlaza, na switirhisiwa swa xiyimo xa le henhla, nkoka wa yona wu ta ya emahlweni wu tlakuka.
