1. Amavuta ya vinyl silicone ni iki?
Izina ryimiti: amavuta abiri ya vinyl silicone
Ibintu nyamukuru biranga imiterere ni uko igice cyitsinda rya methyl (Me) muri polydimethylsiloxane gisimburwa na vinyl (Vi), bigatuma habaho polymethylvinylsiloxane ikora. Amavuta ya Vinyl silicone yerekana imiterere yumubiri wamazi bitewe nuburyo bwihariye bwimiti.
Amavuta ya Vinyl silicone agabanijwemo ubwoko bubiri: amavuta ya vinyl silicone ya nyuma hamwe namavuta menshi ya vinyl silicone. Muri byo, amavuta ya vinyl silicone ya terminal arimo cyane cyane vinyl polydimethylsiloxane (Vi-PDMS) hamwe na vinyl polymethylvinylsiloxane (Vi-PMVS). Bitewe nibintu bitandukanye bya vinyl, bifite imiterere itandukanye yo gusaba.
Uburyo bwa reaction ya amavuta ya vinyl silicone asa nubwa dimethicone, ariko kubera itsinda rya vinyl mumiterere yaryo, rifite reaction nyinshi. Muburyo bwo gutegura amavuta ya vinyl silicone, inzira yo gufungura impeta iringaniza ikoreshwa cyane. Inzira ikoresha octamethylcyclotetrasiloxane na tetramethyltetravinylcyclotetrasiloxane nkibikoresho fatizo, kandi ikora urwego rwumunyururu hamwe na degere zitandukanye za polymerisation binyuze mubitekerezo bifungura impeta iterwa na aside cyangwa alkali.
2. Ibikorwa biranga amavuta ya vinyl silicone
1. Ntabwo ari uburozi, uburyohe, nta mwanda wubukanishi
Amavuta ya Vinyl silicone ni ibara ritagira ibara cyangwa umuhondo, amazi abonerana adafite uburozi, impumuro nziza, kandi nta mwanda wubukanishi. Aya mavuta ntashobora gushonga mumazi, ariko arashobora kutumvikana na benzene, dimethyl ether, methyl ethyl ketone, tetrachlorocarbon cyangwa kerosene, kandi bigashonga gato muri acetone na Ethanol.
2. Umuvuduko muto wumuyaga, flash point yo hejuru hamwe nu muriro, munsi yo gukonjesha
Iyi miterere ituma vinyl silicone itemba neza kandi idahindagurika mubushyuhe bwinshi cyangwa ibidukikije bidasanzwe, bityo bikaramba kuramba mubikorwa bitandukanye.
3. Gukora cyane
Vinyl silicone ifunze kabiri hamwe na vinyl kumpande zombi, bigatuma ikora cyane. Mubikorwa bya catalizator, amavuta ya vinyl silicone arashobora kwitwara hamwe nimiti irimo hydrogène ikora hamwe nandi matsinda akora kugirango bategure ibicuruzwa bya silikoni bitandukanye bifite umwihariko. Mugihe cyo kubyitwaramo, amavuta ya vinyl silicone ntabwo arekura ibindi bintu bifite uburemere buke bwa molekuline kandi bifite bike byo guhindura reaction, bikarushaho kunoza imikorere mubikorwa byinganda.
4. Kunyerera bihebuje, ubworoherane, umucyo, ubushyuhe no guhangana nikirere
Iyi miterere ituma amazi ya vinyl silicone afite uburyo bwinshi bwo gukoresha muguhindura plastike, resin, amarangi, ibifuniko, nibindi. Muri icyo gihe, irashobora kandi gukoreshwa nkibikoresho fatizo fatizo mugukora silicone yubushyuhe bwo hejuru. reberi (HTV) kugirango yongere imbaraga nubukomezi bwa silicone. Mu gukora ibishishwa bya silicone y'amazi, amavuta ya vinyl silicone nayo ni ibikoresho by'ibanze byo gutera inshinge za silicone reberi, kole ya elegitoronike, hamwe na rubber ikora ubushyuhe.
3. Gukoresha amavuta ya vinyl silicone
1. Ibikoresho fatizo byubushyuhe bwo hejuru bwa silicone reberi (HTV):
Amavuta ya Vinyl silicone avangwa na crosslinkers, imbaraga zongerera imbaraga, amabara, imiti igenzura imiterere, imiti igabanya ubukana, nibindi, kandi ikoreshwa mugutegura ubushyuhe bwo hejuru bwa silikoni ya reberi ya rubber. Rubber ya silicone ifite ituze ryiza kandi iramba mubihe byubushyuhe bwo hejuru, kandi ikoreshwa cyane mubihe bitandukanye bisaba kurwanya ubushyuhe bwinshi no kurwanya ruswa.
2. Ibikoresho byingenzi bya reberi ya silicone yamazi:
Amavuta ya silicone ya Vinyl arashobora gukoreshwa afatanije na hydrogène irimo crosslinkers, catalizike ya platine, inhibitor, nibindi, kugirango bategure reberi yongeyeho amazi ya silicone. Iyi reberi ya silicone ifite amazi meza, imiterere kandi yoroheje, kandi ikoreshwa cyane mubikorwa bya silicone, imyenda, firime zirinda nizindi nzego.
3. Gutegura ibikoresho bishya:
Amavuta ya Vinyl silicone akora hamwe nibikoresho bitandukanye kama nka polyurethane na acide acrylic kugirango bategure ibikoresho bishya nibikorwa byiza. Ibi bikoresho bishya bifite ibiranga kurwanya ikirere, kurwanya gusaza, kurwanya ultraviolet, no gukomera gukomeye, kandi bikoreshwa cyane mubitambaro, ibifunga, ibikoresho bifunga kashe hamwe nizindi nzego.
4. Porogaramu mubijyanye na electronics:
Amavuta ya Vinyl silicone akoreshwa cyane mubikoresho bya elegitoronike, ibyuma bifata ubushyuhe, ibyuma bifata amatara ya LED, gupakira LED hamwe no kubumba ibikoresho bya elegitoroniki. Itanga uburyo bwiza bwo gufunga kurinda ibikoresho bya elegitoroniki byoroshye cyane nibice byanduye cyangwa bigenda, byemeza ko ibikoresho bya elegitoroniki bihamye kandi byizewe.
5. Ibikoresho byingenzi byibanze byo kurekura:
Umukozi wo kurekura agira uruhare mukurinda gufatira mubikorwa byinganda, bigira uruhare mukurekura neza ibicuruzwa no kuzamura umusaruro.
4. Vinyl silicone yamavuta yiterambere ryisoko
1. Kwagura umurima wo gusaba
Amazi ya Vinyl silicone ntabwo akoreshwa cyane mu miti gakondo, imiti, imiti ya elegitoroniki n’izindi nzego, ariko kandi agira uruhare runini mu kwisiga no kwisiga ku giti cye, amavuta yo kwisiga, gutwara amavuta, ibikoresho bifunga kashe, wino, plastiki na reberi. Cyane cyane mubijyanye no kwisiga, amavuta ya vinyl silicone akoreshwa cyane mugukora amasabune, shampo, moisturizers, amavuta yo kwisiga, kondereti nibindi bicuruzwa kubera amavuta meza kandi byoroshye.
2.Amavuta mashya ya vinyl silicone
Ababikora barashobora guteza imbere ibintu byinshi byamazi ya vinyl silicone ikora mugukomeza kunoza amata no kunoza uburyo bwo kubyaza umusaruro kugirango bongere ubwiza, amazi, ituze nibindi bintu byamavuta ya vinyl silicone. Nkumucyo ukiza, cationic-curing, biocompatible, nibindi, bikwiranye nurwego rwagutse rwa porogaramu.
3.Vinyl silicone amavuta yo gutegura icyatsi
Hamwe no kurushaho kumenyekanisha ibidukikije, guteza imbere uburyo bushya bwangiza ibidukikije kugirango hategurwe icyatsi kibisi cyamavuta ya silicone, nko gukoresha monomers biodegradable, catalizator ikomeye, amazi ya ionic, nibindi, kugirango ugabanye ikoreshwa ryumuti wuburozi na by- ibicuruzwa, no kugera ku majyambere arambye.
4.Nano vinyl silicone yamavuta
Gushushanya no guhuza ibikoresho byamavuta ya vinyl silicone hamwe na nanostructures idasanzwe, nka vinyl silicone yamavuta nanoparticles, nanofibers hamwe na brushes ya molekulari, nibindi, kugirango utange ibikoresho bifite ingaruka zidasanzwe zubuso hamwe nibiranga interineti, hanyuma ufungure imirima mishya ikoreshwa.
5.Gupakira, kubika no gutwara
Iki gicuruzwa nigikoresho gikora imiti, kandi ntigishobora kuvangwa numwanda (cyane cyane catalizator) mugihe cyo kubika no gutwara, kandi ugomba kwirinda guhura nibintu bishobora gutera imiti yacyo nka acide, alkalis, okiside, nibindi, nibindi, kugirango wirinde gutandukana, kandi ubike ahantu hakonje kandi humye. Ibicuruzwa ntabwo ari ibintu biteje akaga kandi birashobora gutwarwa ukurikije ibicuruzwa bisanzwe.
