Jilciyeyaasha silicone

Silikoonnada waxa loo kala saaray sidii qayb gaar ah oo polymers-ka dadku-sameeyey oo laga soo qaatay birta silikoon sannadkii 1904. Waxa loo isticmaalay samaynta kiimikooyinka jilicsan ee dharka ilaa 1960-kii.Markii hore, polydimethylsiloxanes aan la beddelin ayaa la isticmaalay.Dabayaaqadii 1970naadkii, soo bandhigida aminofunctional polydimethylsiloxanes ayaa furay cabbiro cusub oo jilicsanaanta dharka.Erayga 'silicone' waxa loola jeedaa polymer macmal ah oo ku salaysan qaab silikoon iyo ogsijiin beddelka ah (siloxane bonds).Radiuska atomiga weyn ee atomka silikoon wuxuu ka dhigayaa dammaanadda silikoon-silikon mid aad u tamar yar, markaa silanes (Si_nH_2n+1) aad bay uga xasilloon yihiin alkenes.Si kastaba ha ahaatee, curaarta silikoon-oxygen ayaa aad uga tamar badan (qiyaastii 22Kcal/mol) marka loo eego curaarta kaarboon-ogsajiinta.Silikoonku waxa kale oo uu ka soo qaataa qaab-dhismeedkeeda kitone u eg (silico-ketone) oo la mid ah acetone.Silikoonyadu waa xor aan lahayn bonds labanlaab ah oo ku jira laf dhabartooda mana aha oxocompounds.Guud ahaan, daawaynta silikoon ee dundu waxay ka kooban tahay silikoon polymer (badanaa polydimethylsiloxanes) emulions laakiin maaha kuwa silane monomers ah, kuwaas oo laga yaabo inay xoreeyaan kiimikooyinka halista ah (tusaale hydrochloric acid) inta lagu jiro daaweynta.

Silikoonyadu waxay soo bandhigaan qaar ka mid ah guryaha gaarka ah oo ay ku jiraan xasilloonida oksaydhka kuleylka, qulqulka heerkulka hooseeya, isbeddelka viscosity hoose ee heerkulka, isku-buufinta sare, kacsanaanta dusha hoose, hydrophobicity, guryaha korantada ee wanaagsan iyo khatarta dabka hooseysa sababtoo ah qaab-dhismeedkooda organic-organic iyo dabacsanaanta curaarta silicone .Mid ka mid ah sifooyinka ugu muhiimsan ee qalabka silikoonku waa waxtarkooda marka la eego qadar aad u hooseeya.Qadar aad u yar oo silikoon ah ayaa loo baahan yahay si loo gaaro sifooyinka la rabo, taas oo hagaajin karta kharashka hawlaha dharka iyo hubinta saameynta ugu yar ee deegaanka.

Habka loo jilciyo daaweynta silikoon ayaa sabab u ah sameynta filim dabacsan.Tamarta la dhimay ee loo baahan yahay wareegtada curaarta ayaa ka dhigaysa laf dhabarta siloxane mid dabacsan.Dhigista filimka dabacsan waxay yaraynaysaa isku-xidhka interfibre iyo dhexda.

Markaa dhamaystirka silikoon ee duntu waxay soo saartaa gacan jilicsan oo gaar ah oo ay weheliso waxyaabo kale sida:

(1) jilicsanaan

(2) Dareen dufan leh

(3) Jir wanaagsan

(4) Iska caabin laxaad leh oo la hagaajiyay

(5) Awoodda ilmada oo hagaagtay

(6) Wasakhnimada oo hagaagtay

(7) Sifooyin ka hortag iyo ka hortag wanaagsan

Sababtoo ah qaabdhismeedkooda inorganic-organic iyo dabacsanaanta curaarta siloxane, silicones waxay leeyihiin sifooyinka soo socda ee gaarka ah:

(1) Deganaanshaha kulaylka/oxidative

(2) Socodka heerkulka hooseeya

(3) Isbeddel hoose ee viscosity oo leh heerkul

(4) Cadaadis sare

(5) kacsanaan hoose oo dusha sare ah (faafin)

(6) Dabka oo yaraada

Silikoonyadu waxay leeyihiin codsi aad u ballaaran oo ku saabsan farsamaynta dharka, sida saliidaha fiber-ka ee miiqinta, mashiinnada tolida xawaaraha sare leh, dabaysha iyo goynta, sida xidhayaasha wax-soo-saarka nonwoven, sida antifoam ee midabaynta, sida jilicsanayaasha daabacaadda, dhamaystirka iyo dahaarka.
