Ezweni lezinhlanganisela zamakhemikhali, i-ethyl silicate ne-tetraethyl silicate zivame ukukhulunywa ngazo ngokusetshenziswa kwazo okuhlukahlukene kanye nezakhiwo eziyingqayizivele. Nakuba zingase zibonakale zifana, izici zazo ezihlukene kanye nokusetshenziswa kwazo kwenza ukuqonda umehluko ube obalulekile kunoma ubani osebenza nazo ezinqubweni zezimboni noma zokukhiqiza.

Ukuqonda i-Ethyl Silicate ne-Tetraethyl Silicate

I-Ethyl silicateiyiqembu lama-silicon-based compounds ngokuvamile ahlanganisa ingxube yama-oligomers. Ngokuyinhloko isetshenziswa njengesibophezelo, ikakhulukazi kuma-coatings, futhi ithola izinhlelo zokusebenza ekukhiqizweni kwezinto eziphikisayo kanye nokusakazwa kokutshalwa kwezimali okunembayo.

Ngokolunye uhlangothi,i-tetraethyl silicate(evame ukubizwa ngokuthi i-TEOS) iyinhlanganisela ehlanzekile lapho i-athomu ye-silicon iboshelwe emaqenjini amane e-ethoxy. I-TEOS isetshenziswa kabanzi ekucubunguleni i-sol-gel, izinto ezisuselwa ku-silica, nanjengesandulela ekwenziweni kwengilazi nezitsha zobumba.

Ukubunjwa kanye Nesakhiwo Samakhemikhali

Umehluko ophawuleka kakhulu phakathi kwe-ethyl silicate ne-tetraethyl silicate usekuhlanganiseni kwawo kwamakhemikhali.

• I-Ethyl silicate iqukethe ingxube yezinhlanganisela ze-silicon futhi ingase ihluke ngesisindo samangqamuzana kuye ngokwakhiwa okuqondile.

• I-Tetraethyl silicate, njengoba igama liphakamisa, iyinhlanganisela eyodwa enefomula ethi Si(OC2H5)4, enikeza ukuziphatha okungaguquki ekuphenduleni kwamakhemikhali.

Lo mehluko wesakhiwo unomthelela ekusebenzeni kabusha kwawo kanye nokufaneleka kwezinhlelo zokusebenza ezithile.

Ukuphinda usebenze kanye nokubamba

Uma uqhathanisai-ethyl silicate vs. tetraethyl silicate, ukusebenza kabusha kwabo kuyisici esibalulekile okufanele sicatshangelwe.

• I-Tetraethyl silicate ingena ku-hydrolysis ngokubikezelwa, okuyenza ilungele izinqubo ezilawulwayo ezifana nokuhlanganiswa kwe-sol-gel.

• I-Ethyl silicate, enokwakheka kwayo okuhlukahlukene, ingase ibonise amazinga ahlukene e-hydrolysis kuye ngokwakhiwa okuthile, okungaba yinzuzo kwezinye izinhlelo zokusebenza ezidinga ukuguquguquka.

Zombili izinhlanganisela zizwela umswakama futhi zidinga ukugcinwa ngokucophelela ezitsheni ezivaliwe ukuvimbela ukusabela ngaphambi kwesikhathi.

Izicelo kanye Izimboni

Ukwehluka kwezakhiwo zabo kuholela ekusetshenzisweni okuhlukile kuzo zonke izimboni:

1.Ama-coatings kanye nama-Adhesives

I-Ethyl silicate isetshenziswa kabanzi njengesibophezelo embotsheni nasezinamatheleni, ikakhulukazi ezinsizeni ezisezingeni eliphezulu nezimelana nokugqwala. Ukuguquguquka kwayo kanye nezakhiwo eziqinile zokubopha kuyenza ibe isithako esibalulekile kule mikhiqizo.

2.Izinqubo ze-Sol-Gel

I-Tetraethyl silicate iyisisekelo kubuchwepheshe be-sol-gel, lapho isebenza khona njengesandulela sokukhiqiza izinto ezisekelwe ku-silica. Le nqubo ibalulekile ekudaleni imicu ye-optical, i-ceramics, nezinye izinto ezithuthukisiwe.

3.Precision Casting

I-Ethyl silicate ivamise ukusetshenziswa ekufakweni kwe-investimenti njengesibophezelo sesikhunta se-ceramic. Ikhono layo lokumelana nezinga lokushisa elidlulele futhi linikeze ukunemba kobukhulu libaluleke kakhulu kulolu hlelo lokusebenza.

4.Ukukhiqizwa Kwengilazi Nobumba

I-Tetraethyl silicate idlala indima ebalulekile ekukhiqizeni izingilazi ezikhethekile nezitsha zobumba. I-hydrolysis yayo ebikezelwayo ivumela ukulawula okunembile phezu kwezakhiwo zezinto zokugcina.

Ukucatshangelwa Kwemvelo Nokuphepha

Zombili lezi zinhlanganisela zidinga ukuphathwa ngendlela efanele ngenxa yokuphinda zisebenze kanye nomthelela ongaba khona kwezemvelo. Ukugcinwa ngendlela efanele, ukungena komoya, kanye nokusetshenziswa kwezinto zokuzivikela (personal protective equipment (PPE) kubalulekile uma usebenza ngala makhemikhali. Ukwengeza, ukuqonda imithetho yendawo mayelana nokulahlwa kwazo kubalulekile ukuze kuncishiswe izingozi zemvelo.

Ukukhetha Inhlanganisela Elungile

Lapho unquma phakathiI-ethyl silicate ne-tetraethyl silicate, kubalulekile ukuhlola izidingo ezithile zephrojekthi yakho. Izinto ezifana nokusebenza kabusha okufunayo, uhlobo lohlelo lokusebenza, nokucatshangelwa kwemvelo kufanele kuqondise ukukhetha kwakho.

Imicabango yokugcina

Ukuqonda umehluko phakathi kwe-ethyl silicate ne-tetraethyl silicate kungakusiza wenze izinqumo ezinolwazi ngezinqubo zakho zezimboni noma zokukhiqiza. Inhlanganisela ngayinye inikeza izinzuzo eziyingqayizivele, futhi ukukhetha okulungile kuqinisekisa ukusebenza kahle kanye nemiphumela emihle.

Uma ufuna isiqondiso sochwepheshe ekukhetheni inhlanganisela engcono kakhulu yezidingo zakho, thintana I-Fortune Chemicalnamuhla ukuze uthole izixazululo ezihambisanayo nokusekelwa.
