Amanani aphathekayo ayinkomba. Ukuhlanzeka kanye neminye imikhawulo yokwamukela iqinisekiswa ekucacisweni okuvunyelwene ngakho kanye ne-COA yamanje.

I-MTMS inamaqembu amathathu e-hydrolyzable methoxy. I-Hydrolysis yakha amaqembu e-silanol, angahlangana abe yizakhiwo ze-siloxane. Ukuziphatha kokusabela kuncike ezintweni ezihlanganisa i-pH, ukugxilisa ingqondo, izinga lokushisa kanye ne-catalyst.

Izinhlelo zokusebenza

1. Izingubo kanye Nopende

I-Sol-gel coatings: Isandulela se-methyl-containing siloxane kanye namanethiwekhi e-hybrid coating.
Ukuthuthukiswa kokwakheka: Kusetshenziswa lapho idizayini yokumboza idinga ukuphambana okulawulwayo noma ukuguqulwa kwendawo.

2. Ama-Sealants nama-Adhesives

I-Crosslinking: Isithako ekwakhekeni kwe-silicone ye-alkoxy-cure.
Ukuphatha umswakama: Kungasebenza njengomuthi okhipha amanzi kumasistimu ahambisanayo.

3. Izinto zokwakha

Ukwelashwa ngamaminerali: Impahla engavuthiwe yokwelapha okuxosha amanzi.
Ukuhlolwa kokusebenza: I-substrate, ukungena, izimo zokwelapha nokuqina kufanele kuhlolwe ngokusetshenziswa okuhlosiwe.

4. Ama-Silicone Resins

I-resin emaphakathi: Ihlinzeka ngamayunithi aphethe i-methyl kumanethiwekhi e-siloxane resin.
Amasistimu we-Hybrid: Angasetshenziswa namanye ama-silane afanelekile noma ama-silica precursors.

5. Ukwelashwa kokugcwalisa kanye ne-Pigment

Ukulungiswa komphezulu: Kusetshenziselwa ukwenza izindawo ezifanelekile ezingaphili zibe ne-hydrophobic.
Ukuhlakazeka: Ingasiza i-pigment noma ukusabalalisa kwesigcwalisi ekwakhekeni okuhambisanayo.

Ukupakisha kanye Nesitoreji

Ukupakisha: 200 kg izigubhu; qinisekisa ezinye izinketho zokupakisha ngekhotheshini.
Isitoreji: Gcina uvalwe ngokuqinile endaweni epholile, eyomile, enomoya omuhle, evikelwe emswakameni nasezindaweni zokuthungela.
Ngemva kokuvulwa: Nciphisa ukuchayeka emoyeni onomswakama futhi uphinde uvale ngokushesha ukuze unciphise i-hydrolysis ngaphambi kwesikhathi.

Ukuphepha Nokuphatha

Ukulawula umlilo: Uketshezi oluvutha kakhulu kanye nomhwamuko. Susa imithombo yokuthungela futhi ulawule i-static ngesikhathi sokudlulisa.
I-Hydrolysis byproduct: Ukuthintana nomswakama kukhipha i-methanol. Sebenzisa umoya ofanele futhi ugweme ukuhogela noma ukuthintana ngqo.
Ukuvikela: Khetha amagilavu nokuvikela iso kulo msebenzi. Landela i-SDS yebanga elithile yamanje ukuze uthole izingozi eziphelele zezempilo, izilawuli zokuchayeka kanye nezidingo zokulahlwa.

imibuzo ejwayelekile ukubuzwa

Ingabe I-MTMS Ingengezwa Ngqo Okwakhiweni Okusekelwe Emanzini?

Ukwengeza okuqondile kungase kubangele i-hydrolysis ngaphambi kwesikhathi kanye nokujiya. Sebenzisa indlela yokufakwa eqinisekisiwe futhi uhlole ukuzinza kokwakheka nokukhishwa kwe-methanol.

Uyini Umehluko Phakathi kwe-MTMS ne-MTES?

I-MTMS iqukethe amaqembu e-methoxy, kuyilapho i-methyltriethoxysilane (MTES) iqukethe amaqembu e-ethoxy. I-MTMS ngokuvamile isabela ngokushesha ngamanzi ngaphansi kwezimo ezifanayo. Ukufaka esikhundleni kudinga ukuhlolwa kwe-hydrolysis kanye nenqubo yokwelapha.

Ingabe i-MTMS ingakwazi ukufaka esikhundleni se-Aminosilane noma i-Epoxysilane?

Hhayi ngokuzenzakalelayo. I-MTMS ine-methyl substituent, kuyilapho ama-aminosilanes nama-epoxysilanes ephatha amaqembu ezinto eziphilayo asebenzayo. Khetha i-silane ngokuya nge-substrate, i-resin chemistry kanye nendlela yokwelapha.
