Ibikoresho byo gufunga bya silicone byabaye amahitamo ya mbere y’abahanga ndetse n’abakora DIY iyo bigeze ku gufunga ahantu hatandukanye. Ibikoresho byo gufunga bya silicone bifite imiterere myiza yo gufata neza no gukora ibintu bitandukanye, bitanga imbaraga zo kuramba mu bikorwa bitandukanye. Mu moko y’ibikoresho byo gufunga bya silicone bigurishwa ku isoko, ibikoresho byo gufunga bya silicone bya alkoxy na silicone sealants bya acetoxy ni ubwoko bubiri buzwi cyane. Muri aya makuru, turareba mu buryo bwimbitse imiterere y’ibi bikoresho byo gufunga, ibyiza n’ibibi byabyo, kandi tugufashe kumenya amahitamo meza ajyanye n’ibyo ukeneye byihariye.
1. Itandukaniro mu miterere:
Ubwa mbere, reka turebe itandukaniro riri hagati ya alkoksi na asetoksi. Itsinda rya alkoksi rigizwe n'itsinda rya alkyl (R-) rihujwe na atome ya ogisijeni (-O-). Mu by'ukuri, ni uruvange rw'itsinda rya alkyl na ogisijeni.
Mu rundi ruhande, acetoxy ikomoka kuri aside asetiki. Irimo itsinda rya acetyl (CH3CO-) rihujwe na atome ya ogisijeni (-O-). Bityo, acetoxy ishobora gufatwa nk'itsinda rya alkyl risimbuwe na ogisijeni mu gice cya acetyl.
Itandukaniro mu miterere rituma habaho itandukaniro mu miterere ya shimi n'uburyo ihinduka hagati y'amatsinda ya alkoxy na acetoxy. Nk'itsinda ry'imikorere ya aliphatic, alkoxy igaragaza imiterere ya nucleophilic kandi rimwe na rimwe ikora nk'itsinda rivamo. Iyi myitwarire iterwa ahanini n'imiterere n'ibisimbura itsinda rya alkyl rifatanye na atome ya ogisijeni. Kubera ko amatsinda ya alkoxy adakora cyane, hakenewe electrophile ikomeye cyangwa catalyst kugira ngo itangire reaction.
Mu buryo bunyuranye, amatsinda ya acetoxy agaragaza uburyo butandukanye bwo gukora bitewe n'uko amatsinda ya acetyl ariho. Acetyl moiety na karuboni yayo ifite igice cyayo cya karuboni bigira uruhare mu gutuma itsinda rya acetoxy rikora neza. Kubwibyo, itsinda rya acetoxy rigira uruhare runini mu gukora acetylation reaction, rigashyira acetyl moiety ku zindi molekile. Uburyo acetylation reactions buri hose mu gukora imiti, ibintu karemano n'ibindi bintu bitandukanye by'umwimerere.
2. Alkoxy silicone sealants: Gusohora uburyo bushya bwo gukoresha
Ibifunga bya Alkoxy silicone ni ibifunga byakozwe mu buryo bwihariye bishingiye ku ikoranabuhanga rya alkoxy. Ibi bifunga bizwiho ubushobozi bwo guhuza ibintu bitandukanye, harimo ikirahure, ibumba, na pulasitiki zimwe na zimwe. Ubushobozi bwabyo bwo kwihanganiraubushyuhe bwinshinakurwanya imirasire ya UVbibagira amahitamo ya mbere yo gukoreshwa hanze. Byongeye kandi, ibifunga bya silikoni bya alkoxylated bifite ubushobozi bwiza bwokurwanya ikirere, bigamije gutanga umusaruro urambye. Bitewe n'ukomodulus nkekandi byoroshye cyane, bishobora kwakira imigendere y'ingingo, bigatuma ziba nziza cyane mu gukoresha ingufu. Akamaro gakomeye k'ibifunga bya silikoni bya alkoxylated ni ukoimpumuro nkeyamu gihe cyo kuzitunganya, ibyo bigatuma zoroherwa no kuzikoresha ahantu hafunze.
3. Ibifunga bya Acetoxy Silicone: Byageragejwe kandi byageragejwe
Ku rundi ruhande, ibifunga bya silikoni bya acetoxy, bikoresha ikoranabuhanga ryo gukangura acetoxy. Ibi bifunga bimaze imyaka ibarirwa muri za mirongo bikoreshwa cyane kandi bizwiho ubushobozi bwo gukangura ibintu bitandukanye. Bifatanya cyane n'ibikoresho by'ubwubatsi bisanzwe, birimo ikirahure, icyuma na ceramic. Ibifunga bya silikoni bya acetoxy birangwa nogukira vubakandi ni byiza cyanekurwanya ubushuheUku kuvura vuba bituma imishinga yihuta kandi yoroshye. Ariko, menya ko ibifunga bya silicone bya acetoxy bishobora gutanga impumuro nk'iya vinegere uko bikira, bityo guhumeka neza ni ingenzi cyane.
4.Hitamo agakoresho gakwiye ko gufunga silicone
Gusobanukirwa imiterere yihariye ya buri bwoko bwa silicone sealant ni ingenzi cyane kugira ngo ufate icyemezo gishingiye ku makuru. Ibintu nk'imbaraga z'ubumwe burambye, ubushobozi bwo guhuza, igihe cyo gukira, ubworoherane, impumuro nziza n'ibisabwa mu mushinga byihariye bigomba kuzirikanwa. Aho kurwanya imirasire ya UV, ubushyuhe bukabije n'ikirere cyo hanze ari ingenzi cyane, silicone sealants ya alkoxylated ikunze gukundwa. Acetoxy silicone sealants ifite ubushobozi bwo gukira vuba kandi ni amahitamo meza ku mishinga isaba igihe cyo guhindura ibintu vuba no guhuza bikomeye. Nanone, ni ngombwa kumenya ko ubwoko bwombi bwa silicone buboneka mu mabara atandukanye, butanga amahitamo meza ku mikoreshereze isaba irangi ryiza.
Umwanzuro
Muri rusange, ibifunga bya silikoni bya alkoxy na acetoxy bitanga inyungu zidasanzwe bitewe n'ibikenewe mu mushinga runaka. Icyemezo cya nyuma giterwa n'imiterere y'ubudodo, igihe cyo kuvura, ubworoherane, impumuro nziza n'ibidukikije. Ukurikije amakuru yatanzwe muri iyi nkuru, ushobora guhitamo neza ibifunga bya silikoni bihuye neza n'ibyo ukeneye.
