Ukuqonda iIipropathi zoku SolulaI-Tetrathyl Silicate(Tes)ibalulekile kumashishini asebenzisa le ndawo iguquguqukayo kwiImali, imihlambi, i-ceramics, kunye ne-elektroniki. I-Tes, ekwabizwa ngokubaI-Silicate, yinto esetyenziswayoI-Slica Precursoreziziphatha ngokwahlukileyo kwizinyithi ezahlukeneyo. Umoya wayo uchaphazela kakuhle indlela egcinwe ngayo, ephathwe, kwaye isetyenziswa kwiinkqubo ezahlukeneyo. Kweli nqaku, siza kuhlolaUkunyibilisela kwe-tetrathyl silithy enamanzi kunye nezinyibilikisi, kwaye unikezele ngeengcebiso ezifanelekileyo zokwenza umsebenzi wayo kwizicelo zemveliso.
Isizathu sokuba u-Solubity mihle kwiinkqubo zemizi-mveliso
Kwi chemistry yezamashishini,Ukuqonda i-solity ye-coloubidibalulekile ukuqinisekisaUkwenziwa ngokufanelekileyo, isicelo, kunye nokugcinwa. KubaI-Tetrathyl Silicate, uSoliday udlala indima ephambili kwiIndlela Iqala Ngayo nezinye izintokwaye ziza njaniIinethiwekhi ze-silicaNgexesha le-hydrolysis.
I-Tes isetyenziswa kwizicelo aphoUkuqulunqwa kwesilicaIyafuneka. Nangona kunjalo, yayoUkusebenza kwakhona ngamanzi kunye nokuhambelana nezinyibilikisi zezinto eziphilayokufuneka ilawulwe ngononophelo ukufezekisaukusebenza kwemveliso oyifunayo.
Ukungasebenzi kwe-tetrathyl silicote emanzini
Enye yezona mpawu zibalulekileyo zeI-Tetrathyl SilicateyiyoUkungasebenzi kakuhle emanzini. Xa i-TES iza kudibana namanzi, iphantsi kweI-Hydrolysis yokuphendula, ekhokelela ekumiselweni kweIsilikic acidne-ethanol.
IZIPHUMO ZOBUCHULE UKUYA:
• I-Tes yileinyibilikaemanzini kodwa iphinda isebenze ngokukhawulezaI-Silica Gel.
Inkqubo ye-hydrolysis yileIkhawuleziswe phambi kobuso be-acidic okanye isiseko se-catalysts.
Njengoko i-TES iqala ngamanzi, iyenza aInethiwekhi ye-Silicainokusetyenziselwa ukwenza i-pares, imihlambi kunye nezityholo.
Ingcebiso esebenzayo:
Xa uphatha i-tes kwizicelo ezisezantsi, kubalulekileLawula inkqubo ye-hydrolysisUkuthintela ukubethwa kwangaphambili kwaye kufezekise iI-iyunifomu ye-silica.
Ukuziphatha kwe-tetrathyl silithy kwi-onsing slices
Ngokungafaniyo nokuphendula kwayo ngamanzi,I-Tetrathyl Silicote inyibilike kakuhle kwizinyithi ezininzi zezinto eziphilayo. Isomeleza yayo ngaphakathiI-alcohols, iKetones, kunye nee-hydrocarbonsyenza ukuba kube kuguquguqukayoIfomu eyahlukeneyo yemizi-mveliso.
Izinyibilikisi eziqhelekileyo zeTs:
1.I-Ethanol kunye neMetanol:I-Tes inyibilike ngokulula ngaphakathiIzinyibilikisi ezisekwe ebomini, edla ngokusetyenziswa kwi-cayings kunye nee-cacheves zokufezekisaIsicelo esigudileyokwayeI-Iyunifomu yefilimu.
2.I-Acetone:Njengokusetyenziswa ngokubanziIKeotone Schoolvent, i-acetone inokuqhelisela i-tis kwaye iqhelekile kwiUkucoca kunye nokunciphaIfomula.
3.I-toulene kunye neXyyne:EziIzinyibilikiselo ze-hydrocarbonziyahambelana ne-tis kwaye zihlala zisetyenziswaI-DoedIngsUkuqina okuphuculweyo kunye ne-adhesion.
Ingcebiso yeProp:
Khetha isolvent efanelekileyo esekwe kwiIimfuno zesicelo. Njengokuba,Izinyibilikisi ezisekwe ebominizilungeleIngubo yokwaphula ngokukhawuleza, ngelixaIzinyibilikiselo ze-hydrocarbonbonelelaukuqina okuphuculweyo.
Izinto ezichaphazela i-tes solula
Izinto ezininzi zinokuba nefuthe kwiUkususwa kwe-tetrathyl silithyl, kubandakanya:
1.Iqondo lokushisa:
Amaqondo obushushu aphezulu anakhoYongeza i-solidalityye-tis kwiinyikima ezithile, kodwa zinakoukukhawulezisa i-hydrolysisXa amanzi akhoyo.
2.Inqanaba le-pH:
I-PH yesisombululo inokuchaphazelaIreyithi ye-hydrolysis. Iimeko ze-acidic okanye ezisisisekoKhawulezisa impendulo, ngelixa ukungathathi hlangothi ph ithe chu.
3.Uxinzelelo:
Ukuxinezeleka kwe-Tes kwi-solvent kunokuchaphazelaUzinzo kunye nokusebenza. Izisombululo eziTheweyozizinzile ngakumbi, ngelixaUkugxininisa okuphezuluinokukhokelela kwiukuqinaokanyeukuhlaselwa.
Ingcebiso esebenzayo:
Xa usenza i-tes,ukubeka iliso kubushushu, i-PH, kunye nokuSebenzaUkufezekisa isombo esinqwenelekayo kunye nokukhuseleka kwesicelo sakho.
Izicelo zeTes ezisekwe kwiPropathi ye-Solbing
