SMC (xaashida xarunta "xaashida" xaashida '') xaashida, isku-darka wax ku oolka iyo waxqabadka sare ee ka kooban, ayaa si tartiib tartiib ah u helaya caan. Thanks to asluubkeeda gaarka ah ee wax soo saarka u gaarka ah, waxay muujineysaa rajo ballaaran oo ku saabsan qaybaha kala duwan sida dhismaha, injineeriyada korantada, iyo gaadiidka, ku duridda muhiimada cusub ee sheyga warshadaha.
Iyada oo ah xaashida wax qabad-sareeya, tayada sare ee go'yaasha SMC waxay ka soo baxaan cilmiga sayniska iyo sicirka si habsami leh loo sameeyay. Loogu talagalay matrix-ka resin, sheyni wuxuu adeegsadaa resin polyester-ka dib-u-eega ah inuu yahay qaab dhismeedka guud, la kulanka shuruudaha waxqabadka ee xaaladaha ugu badan iyadoo la soo bandhigayo qiimo sare. Meelo gaar ah oo leh shuruudaha waxqabadka sare, moodal aad u sarreeya oo leh ephoxy vinyl epinyl epinyl epinyl epinyl epinyl epinyls ayaa sidoo kale la soo saaray, in la wanaajiyo tilmaamayaasha muhiimka ah sida iska caabbinta iyo iska caabbinta heerkulka iyo iska caabbinta heerkulka, bixinta xulashooyinka kaladuwan ee macaamiisha leh baahiyo kaladuwan.
Xulashada agabyada xoojinta waa xudunta ee hubinta xoogga dhisme ee go'yaasha SMC. Shayga ayaa doorta alkali-aleli-ka ah qeybta xoojinta, dabacsan iyadoo la adeegsanayo qaabab galaas oo la jarjarey oo laxiriira nuxurka xaaladaha arjiga ee dhabta ah, iyada oo saamiga uu ku jiro xaashida ay gacanta ku hayaan inta u dhexeysa 20% iyo 50%. Qaab-dhismeedkan sayniska kaliya maahan waxay si wax ku ool ah u xoojineysaa astaamaha farsamada ee looxyada SMC, iyagoo siinaya iska caabin saac ah oo heer sare ah iyo karti-qaadista, laakiin ka fogaanshaha qalalaasaha ay sababaan culeyska xad-dhaafka ah ee ku saabsan howsha xigay.
Ku saabsan buuxinta, guddiyada 'SMC' sinnaan loogu daro kaalshiyamka kaarboon, TALC, iyo qaybaha kale, xisaabaadka 30% -50%. Naqshadeyntani kaliya ma yareynayso qiimaha wax soo saarka laakiin sidoo kale waxay si weyn u wanaajisaa xasilloonida cabbirka ee looxyada, si wax ku ool ah isbeddelada ugu jira isbedelka deegaanka sababta oo ah howsha, iyo adeegsiga, oo lagu hubinayo isku halaynta alaabada isticmaalka muddada-dheer.
Intaa waxaa sii dheer, si loo sii wanaajiyo waxqabadka badeecada, guddiyada SMC sidoo kale waxay ka kooban yihiin waxyaabo badan oo firfircoon oo firfircoon. Ku darista wakaaladaha hooseysa (sida polystyrene) si wax ku ool ah ayaa yareyneysa heerka burburka ee guddiga inta lagu gudajiro geedi socodka wasakhda ah, hubinta saxsanaanta cabirka. Qiyaameyaasha (Magnesium Oxide) si sax ah loo xakameeyo mowqifka maaddada, hagaajinta ku habboonaanta iyo hufnaanta wax soo saarka iyo socodsiinta. Codsiga dib-u-dhiska ololaha ayaa awood u siinaya in ay si guul leh u soo bandhigaan heerka SMC4 V-0, haysashada khataraha firfircoon ee firfircoon, oo si aad ah u yareyneyso apple-ka qalabka qalabka korantada, dhisida kala-goysyada, iyo qaybaha kale ee leh shuruudaha ilaalinta dabka sareeya. Isla mar ahaantaana, sheyga ayaa sidoo kale taageeraya ku-darista iyo midabada u midabka UV, oo aan ku xoojineyn awoodda ka hortagga ee SMC-da ee isticmaalka bannaanka, laakiin sidoo kale waxay u oggolaaneysaa inay ka soo baxaan baahiyaha midabka si ay ula kulmaan baahiyaha suuxinta ee xaaladaha kala duwan.
Xilligan, guddigan SMC oo leh qaab-dhismeedkeena isku-dheellitiran iyo waxqabadka dhameystiran ayaa soo jiitay dareenka warshadaha badan waxaana la filayaa inay door muhiim ah ka ciyaaraan meelo badan oo mustaqbalka ah, iyadoo la siinayo taageero aalad ah oo ku saabsan horumarinta tayada sare ee warshadaha la xiriira.
Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.
