Ehlabathini lemichiza yeekhemikhali, i-ethyl silicate kunye ne-tetraethyl silicate zihlala zikhankanywa ngenxa yezicelo zazo eziguquguqukayo kunye neempawu ezizodwa. Ngelixa zinokubonakala zifana, iimpawu zazo ezahlukeneyo kunye nokusetyenziswa kwazo kwenza ukuqonda umahluko ube yimfuneko kuye nabani na osebenza nabo kwinkqubo yoshishino okanye yokuvelisa.

Ukuqonda i-Ethyl Silicate kunye neTetraethyl Silicate

I-Ethyl silicateliqela leekhompawundi ezisekelwe kwi-silicon ezihlala zibandakanya umxube we-oligomers. Isetyenziswa ngokuyintloko njenge-binder, ngakumbi kwiingubo, kwaye ifumana izicelo kwimveliso yezinto eziphikisayo kunye nokuchaneka kotyalo-mali.

Kwelinye icala,tetraethyl silicate(eyaziwa ngokuba yi-TEOS) yikhompawundi ecocekileyo apho i-athomu ye-silicon idityaniswe kumaqela amane e-ethoxy. I-TEOS isetyenziswa ngokubanzi kwi-sol-gel processing, izinto ezisekelwe kwi-silica, kunye ne-precursor kwi-glass kunye ne-ceramics yokuvelisa.

Ukubunjwa kunye noLwakhiwo lweMichiza

Ukwahlula okuphawulekayo phakathi kwe-ethyl silicate kunye ne-tetraethyl silicate ilele kwimichiza yazo.

• I-Ethyl silicate iqulethe umxube we-silicon compounds kwaye inokwahluka kwi-molecular weight kuxhomekeke kuqulunqo oluthile.

• I-Tetraethyl silicate, njengoko igama libonisa, yikhompawundi enye enefomula ye-Si (OC2H5) 4, enika ukuziphatha okuhambelanayo kwiimpendulo zemichiza.

Lo mahluko wesakhiwo uchaphazela ukusebenza kwabo kwakhona kunye nokufaneleka kwezicelo ezithile.

Ukusebenza kwakhona kunye nokuPhathwa

Xa uthelekisai-ethyl silicate vs. tetraethyl silicate, ukusebenza kwakhona kwabo yinto ebalulekileyo ekufuneka iqwalaselwe.

• I-Tetraethyl silicate ifumana i-hydrolysis ngokuqikelelwa ngakumbi, iyenza ilungele iinkqubo ezifana ne-sol-gel synthesis.

• I-Ethyl silicate, kunye nokwakheka kwayo okungafaniyo, ingabonisa amazinga ahlukeneyo e-hydrolysis ngokuxhomekeke kwimiqulu ethile, enokuba luncedo kwizicelo ezithile ezifuna ukuguquguquka.

Zombini iikhompawundi zinobuthathaka kwaye zifuna ukugcinwa ngononophelo kwizikhongozeli ezivaliweyo ukuthintela ukusabela kwangethuba.

Izicelo kunye namashishini

Umahluko kwiipropathi zabo ukhokelela kwizicelo ezahlukeneyo kuwo wonke amashishini:

1.Iingubo kunye nokuncamathelisa

I-Ethyl silicate isetyenziswa ngokubanzi njenge-binder kwi-coatings kunye ne-adhesives, ngokukodwa kwi-high-temperature kunye nezicelo ezichasene ne-corrosion. Ukuguquguquka kwayo kunye neepropathi ezinamandla zokudibanisa zenza ukuba ibe yinto ebalulekileyo kwezi mveliso.

2.Iinkqubo zeSol-Gel

I-Tetraethyl silicate isisiseko kwi-teknoloji ye-sol-gel, apho isebenza njenge-precursor yokuvelisa izinto ezisekelwe kwi-silica. Le nkqubo ibalulekile ekudaleni iifiber optical, iiseramics, kunye nezinye izinto eziphambili.

3.UkuSasa ngokuchanekileyo

I-Ethyl silicate idla ngokusetyenziswa kwi-investcast casting njenge-binder ye-ceramic molds. Ukukwazi ukumelana nobushushu obugqithisileyo kunye nokubonelela ngokuchaneka kwe-dimensional kuxabiswa kakhulu kwesi sicelo.

4.Imveliso yeglasi kunye neCeramics

I-Tetraethyl silicate idlala indima ebalulekileyo ekuveliseni iiglasi ezikhethekileyo kunye neeseramikhi. I-hydrolysis yayo eqikelelwayo ivumela ulawulo oluchanekileyo kwiipropati zezinto zokugqibela.

Iingqwalasela zokusiNgqongileyo noKhuseleko

Zombini iikhompawundi zifuna ukuphathwa ngoxanduva ngenxa yokuphinda zisebenze kunye nefuthe elinokubakho kokusingqongileyo. Ukugcinwa ngokufanelekileyo, ukungena komoya, kunye nokusetyenziswa kwezixhobo zokuzikhusela (personal protective equipment) (PPE) kubalulekile xa usebenza nale michiza. Ukongeza, ukuqonda imigaqo yendawo yokulahlwa kwayo kubalulekile ukunciphisa umngcipheko wokusingqongileyo.

Ukukhetha iCompound eLungileyo

Xa uthatha isigqibo phakathii-ethyl silicate kunye ne-tetraethyl silicate, kubalulekile ukuvavanya iimfuno ezithile zeprojekthi yakho. Izinto ezinje ngokusebenza kwakhona okunqwenelekayo, uhlobo lwesicelo, kunye nokuqwalaselwa kokusingqongileyo kufuneka kukhokele ukhetho lwakho.

Iingcamango Zokugqibela

Ukuqonda umahluko phakathi kwe-ethyl silicate kunye ne-tetraethyl silicate kunokukunceda wenze izigqibo ezinolwazi kwiinkqubo zakho zoshishino okanye zokuvelisa. Ikhompawundi nganye ibonelela ngeenzuzo ezizodwa, kwaye ukukhetha okulungileyo kuqinisekisa ukusebenza kakuhle kunye neziphumo ezizezona zilungileyo.
