1. Waa maxay saliidda silikoonka vinyl?
Magaca kiimikaad: saliid silikoon vinyl ah oo labajibbaaran
Muuqaalkeeda ugu weyn ee qaabdhismeedka waa in qayb ka mid ah kooxda methyl (Me) ee polydimethylsiloxane lagu beddelay vinyl (Vi), taasoo keentay samaynta polymethylvinylsiloxane fal-celin ah. Saliidda Silikon Vinyl waxay soo bandhigtaa qaabka jireed ee dareeraha dareeraha ah sababtoo ah qaab dhismeedka kiimikada gaarka ah.
Saliida Vinyl Silicone badiyaa waxay u qaybsantaa laba nooc: saliid silikoon vinyl ah oo dhamaadka ah iyo saliid silikoon vinyl ah. Kuwaas waxaa ka mid ah, saliidda silikoon ee vinyl vinyl inta badan waxaa ku jira terminal vinyl polydimethylsiloxane (Vi-PDMS) iyo terminal vinyl polymethylvinylsiloxane (Vi-PMVS). Sababo la xiriira tusmada vinyl ee kala duwan, waxay leedahay astaamo codsi oo kala duwan.
Habka falcelinta ee saliidda silikoonka vinyl waxay la mid tahay tan dimethicone, laakiin sababtoo ah kooxda vinyl ee qaabkeeda, waxay leedahay falcelin sare. Habka diyaarinta saliida silikoonka vinyl, habka falcelinta dheellitirka ee furitaanka giraanta ayaa inta badan la isticmaalaa. Nidaamku wuxuu isticmaalaa octamethylcyclotetrasiloxane iyo tetramethyltetravinylcyclotetrasiloxane sida alaab cayriin ah, wuxuuna sameeyaa qaab dhismeed silsilad ah oo leh heerar kala duwan oo polymerization ah iyada oo loo marayo falcelinta furitaanka giraanta oo ay kataliyaan acid ama alkali.
2. Tilmaamaha waxqabadka ee saliidda silikoon vinyl
1. Aan sun ahayn, aan dhadhamin, wasakh farsamo oo aan lahayn
Saliida Vinyl Silicone waa dareere aan midab lahayn ama huruud ah, oo hufan oo aan sun ahayn, ur lahayn, oo ka nadiif ah wasakh farsamo. Saliiddani waa mid aan lagu milmi karin biyaha, laakiin waxay noqon kartaa mid aan la isku halleyn karin oo leh benzene, dimethyl ether, methyl ethyl ketone, tetrachlorocarbon ama kerosene, iyo wax yar oo ku milma acetone iyo ethanol.
