Yintoni iButyldiglycol?
I-Butyldiglycol (BDG), ekwaziwa ngokuba yi-diethylene glycol monobutyl ether (DGBE), sisinyibilikisi se-glycol ether esine-diethylene glycol backbone epheliswe liqela le-butyl ether. Lilungu elilandelayo lothotho lwe-butyl glycol ether homologous emva kwe-butyl glycol (ethylene glycol monobutyl ether), kunye neyunithi eyongezelelweyo ye-ethyleneoxy enika ubunzima obuphezulu beemolekyuli, iqondo lokubila eliphezulu (~230°C), izinga lokuphuma kwamanzi elicothayo, kunye nokunyibilika kwamanzi okuphuculweyo xa kuthelekiswa ne-butyl glycol. I-BDG ixutywa ngokupheleleyo ngamanzi kwaye ixutywa kunye nezinyibilikisi ezininzi ze-organic, nto leyo eyenza ukuba ibe yiarhente yokudibanisa eguquguqukayo kwiinkqubo ekufuneka zinyibilikise zombini izinto eziphila emanzini kunye neziphila emanzini.
Izicelo zeMveliso yokucoca
Kwindlela yokucoca imveliso, i-BDG isebenza ngokuyintloko njengesihlanganisi kunye nesinyibilikisi segrisi kwizicoci ezixutyiweyo, izicoci zegrisi, kunye nezicoci zomphezulu oqinileyo. Izinga layo lokuphuma kwamanzi lihamba kancinci xa lithelekiswa ne-butyl glycol libonelela ngexesha elide lokuhlala kwiindawo ezingcolileyo, nto leyo ephucula ukunyibilika kwegrisi ngaphambi kokuba ihlanjwe. I-BDG isebenza ngakumbi kwiindawo zokucoca ezixutyiweyo kakhulu apho inani elincinci lezithako ezisebenzayo kufuneka livelise isisombululo esicacileyo nesizinzileyo kuluhlu olubanzi lokunyibilika. Ikwasetyenziswa kwizicoci ze-oven kunye nezicoci zekhitshi ezinzima apho ixesha elide lokudibana nomphezulu libalulekile.
Ukusetyenziswa kunye nobonelelo lwepeyinti kunye nokugquma
Kwizinto zokugquma, i-BDG sisithambisi sokuhlanganisa kunye nesinyibilikisi esithintelayo kwiipeyinti ezisekelwe emanzini kunye neevanishi, siphucula ukwakheka kwefilimu kumaqondo obushushu aphantsi kwaye sinciphisa amabala ebrashi kwiinkqubo ze-alkyd kunye ne-acrylic. I-Terracore Chemicals inikezela nge-BDG yodidi lobuchwephesha kwiidrama kunye nee-IBC zokucoca iimveliso kunye nabavelisi bezinto zokugquma kulo lonke elaseMzantsi Afrika.
