Shaabadaysan ama dhejis silikoon ah waa badeeco awood leh oo dabacsan oo loo isticmaali karo codsiyo badan oo kala duwan. Inkasta oo shaabadaysan silikoon uusan u xoog badnayn sida shaabadaysan ama dhejisyo qaar, shaabadaysan silikoonku wuxuu ahaanayaa mid aad u dabacsan, xitaa marka uu si buuxda u qalalo amala daaweeyayShaabadeeyaha silikoonku wuxuu sidoo kale u adkeysan karaa heerkul aad u sarreeya, taasoo ka dhigaysa mid ku habboon codsiyada la kulma kulaylka sare, sida gaaska matoorka.
Shaabad silikoon ah oo la daweeyay waxay muujisaa iska caabin cimilo oo aad u fiican, iska caabin gabowga, iska caabinta UV, iska caabinta ozone, iska caabinta heerkulka sare iyo kan hoose, iska caabinta gariirka, iska caabinta qoyaanka, iyo sifooyinka ka hortagga biyaha; sidaa darteed, isticmaalkeedu aad buu u ballaaran yahay. Sannadihii 1990-meeyadii, badanaa waxaa loo isticmaali jiray isku xidhka iyo shaabadaynta warshadaha galaaska, sidaa darteed waxaa badanaa loo yaqaan "dhalada muraayadda."

Shaabad-sameeyaha silikoonku wuxuu caadi ahaan ku salaysan yahay 107 (polydimethylsiloxane-ka hydroxy-ka dhammaaday), wuxuuna ka kooban yahay walxo sida polymers-ka miisaanka sare leh ee molecular-ka, balaastikada, buuxinta, wakiilada isku xidha, wakiilada isku xidha, kaaliyayaasha, iwm. Balaastikada si caadi ah loo isticmaalo waxaa ka mid ah saliidda silikoon, saliidda cad, iwm. Buuxiyeyaasha si caadi ah loo isticmaalo waxaa ka mid ah calcium carbonate nano-activated, calcium carbonate culus, calcium carbonate ultrafine, silica fumed, iyo walxo kale.
Shaabadeeyayaasha silikoonku waxay ku yimaadaan qaabab kala duwan.
Sida ku xusan nooca kaydinta, waxaa loo qaybiyaa: laba qaybood (badan) iyo hal qaybood.
Laba qaybood (badan) waxay ka dhigan tahay in shaabad silikoon ah oo loo qaybiyay laba kooxood (ama in ka badan laba) qaybood A iyo B, hal qayb oo keliya ma samayn karto bogsiin, laakiin ka dib marka labada qaybood (ama in ka badan laba) qaybood la isku daro, waxay soo saari doonaan falcelin bogsiin isku xidha si ay u sameeyaan elastomers.
Isku darka waa in la sameeyaa isla markiiba ka hor inta aan la isticmaalin, taasoo ka dhigaysa noocan shaabadaysan ee silikoonka mid aad u adag in la isticmaalo.
Shaabad silikoon ah ayaa sidoo kale ku imaan karta hal badeeco, iyada oo aan loo baahnayn isku darid. Nooc ka mid ah shaabad silikoon ah oo hal badeeco ah ayaa loo yaqaanHeerkulka Qolka Vulcanizing(RTV). Noocan shaabadaysan wuxuu bilaabmaa inuu bogsado isla marka uu hawada soo gaaro - ama, si sax ah, qoyaanka hawada. Sidaa darteed, waxaa lagama maarmaan ah inaad si dhakhso ah u shaqeyso marka aad isticmaaleyso shaabadaysan silikoon RTV.
Shaabad silikoon ah oo hal qayb ka kooban ayaa si qiyaas ah loogu qaybin karaa: nooca deacidification, nooca dealcoholization, nooca deketoxime, nooca deacetone, nooca deamidation, nooca dehydroxylamine, iwm. iyadoo loo eegayo wakiilada isku xidhka kala duwan (ama molecules yar yar ee la soo saaro inta lagu jiro bogsashada) ee la isticmaalo. Kuwaas waxaa ka mid ah nooca deacidification, nooca dealcoholization iyo nooca deketoxime ayaa inta badan suuqa laga isticmaalaa.
Nooca kala-baxa aashitada waa methyl triacetoxysilane (ama ethyl triacetoxysilane, propyl triacetoxysilane, iwm.) oo ah wakiil isku xidha, kaas oo soo saara aashitada aashitada inta lagu jiro bogsashada, oo loo yaqaan "xabagta aashitada". Faa'iidooyinkeedu waa: xoog wanaagsan iyo hufnaan, xawaare degdeg ah oo bogsashada. Qasaarooyinka waa: urta aashitada aashitada oo xanaaqsan, daxalka biraha.
Nooca ka saarista khamriga waa methyl trimethoxysilane (ama vinyl trimethoxysilane, iwm.) oo ah wakiil isku xidha, habka bogsashada wuxuu soo saaraa methanol, oo loo yaqaan "xabagta nooca khamriga ah". Faa'iidooyinkeedu waa: ilaalinta deegaanka, ma daxalayso. Qasaarooyinka: xawaaraha bogsashada gaabiska ah, cimriga kaydinta ayaa waxoogaa liita.
Nooca Deketo oxime waa methyl tributyl ketone oxime silane (ama vinyl tributyl ketone oxime silane, iwm.) oo ah wakiil isku xidha, kaas oo soo saara butanone oxime inta lagu jiro bogsashada, oo si caadi ah loogu yaqaan "xabagta nooca oxime". Faa'iidooyinkeedu waa: ma jiraan ur aad u weyn, ku dhegganaan wanaagsan oo lagu sameeyo agabyo kala duwan. Qasaarooyinka: daxalka naxaasta.
Sida laga soo xigtay isticmaalka alaabada loo qaybiyay: shaabad qaab-dhismeed, shaabad u adkaysta cimilada, shaabad albaab iyo daaqad, isku-xidhka shaabadaynta, shaabad dab-celin ah, shaabad ka hortagta caariyaysi, shaabad heerkul sare leh.
Sida ku cad midabka badeecada ilaa dhibcaha: midabka caadiga ah madow, cad cad oo dhoobo ah, hufan, cawl lacag ah 4 nooc, midabyo kale oo aan ku fulin karno iyadoo loo eegayo shuruudaha macaamiisha.
Waxaa jira noocyo kale oo badan oo kale oo tignoolaji ahaan horumarsan oo shaabad silikoon ah. Nooc, oo loo yaqaancadaadiska xasaasiga ahshaabad silikoon ah, waxay leedahay dhegdheg joogto ah waxayna ku dheggan tahay cadaadis ula kac ah - si kale haddii loo dhigo, inkastoo ay had iyo jeer noqon doonto "dhegdheg," ma dhegi doonto haddii wax si fudud u cadaydo ama u nasto. Nooc kale ayaa loo yaqaanUV or shucaaca la daaweeyayshaabad silikoon ah, waxayna isticmaashaa iftiinka ultraviolet si ay u bogsiiso shaabadeeyaha. Ugu dambeyntii,heerkulbeegshaabadeeye silikoon ah wuxuu u baahan yahay inuu kul ku yeesho si uu u bogsado.
Shaabad silikoon ah ayaa loo isticmaali karaa codsiyo kala duwan. Noocan shaabadaysan waxaa badanaa loo isticmaalaa codsiyada baabuurta iyo kuwa la xiriira, sida qalabka lagu xiro matoorka, iyadoo la isticmaalayo ama aan lahayn gaskets. Sababtoo ah dabacsanaantiisa sare, shaabadaysanuhu sidoo kale waa doorasho wanaagsan oo loogu talagalay hiwaayado badan ama farsamo gacmeedyo.
