Nadiifi-sare Dimethyldichlorosilane Reagent 99%

Tilmaamaha: 200kg / durbaan

Dimethyldichlorosilane, oo inta badan loo soo gaabiyo sida DMDCS, waa dareere aan midab lahayn, qiiqaya oo leh ur daran, sifo chlorosilans fal-celin leh. Badeecadeenu waxay bixisaa nadiif ah 99% la isku halayn karo, iyadoo la hubinayo waxqabadka joogtada ah ee wax soo saarka silikoon polymer, synthesis organosilicon, iyo wax soo saarka alaabada horumarsan.

Sida dhismaha ugu aasaasiga ah ee warshadaha silikoon, DMDCS waxay ku jirtaa booska dhexe ee kimistariga organosilicon. Moleekulku waxa uu ka kooban yahay laba silsiladood oo silikoon-chlorine falgal ah iyo laba kooxood oo methyl ah oo ku xidhan atomka silikoonka dhexe, abuurista dhex dhexaad isku xidhan oo hydrolyzes si ay u sameeyaan polydimethylsiloxane (PDMS) — laf-dhabarta polymers silikoon. Falcelintan hydrolysis, sida caadiga ah waxaa lagu qabtaa xaalado taxaddar leh, waxay abuurtaa oligomers toosan iyo wareeg ah oo siloxane ah kuwaas oo u adeega sida horudhaca dareerayaasha silikoon, elastomers, resins, iyo sealants.

Codsiyada warshadaha, DMDCS waxay u shaqeysaa sidii quudinta aasaasiga ah ee soo saarista saliidaha silikoon ee dimethyl oo leh muuqaalo kala duwan, xeryahooda caag silikoon ah oo wax qabadkoodu sarreeyo, iyo xabagta silikoon u adkaysta cimilada. Ka falcelinta xarunta biyo, aalkolada, iyo amines waxay awood u siinaysaa kontoroolka saxda ah ee miisaanka molecular polymer iyo cufnaanta isku xidhka, taas oo u oggolaanaysa soosaarayaasha in ay ku habboonaadaan sifooyinka walxaha laga soo bilaabo dareerayaasha viscosity hoose ilaa elastomers awood sare leh.

Marka laga soo tago wax soo saarka silikoon badan, dimethyldichlorosilane waxay u adeegtaa sidii wakiilka silyating ee wax ka beddelka dusha sare ee alaabta aan noolaha ahayn, oo ay ku jiraan silica nanoparticles, fiilooyinka dhalada, iyo oksaydhka birta. Daawayntani waxay ka dhigaysaa sagxadaha biyo-baxa, hagaajinta kala firdhisanaanta matries organic iyo kor u qaadida waxqabadka walxaha isku dhafan. Xarunta ayaa sidoo kale ka qaybqaata falcelinta Grignard iyo organolithium ee soo saarista xeryahooda organosilicon ee gaarka ah ee loo isticmaalo codsiyada dawooyinka iyo beeraha.

DMDCS-keena saafiga ah ee 99% waxay la kulmeysaa tilmaamo adag oo loogu talagalay kakooban chlorosilane waxayna yaraynaysaa trichlorosilane iyo wasakhyada kale ee saameeya kinetics-ka polymerization. Darajadan nadiifinta sare ah waxay taageertaa wax soo saarka la isku halayn karo ee soosaarayaasha silikoonka, soosaarayaasha kiimikaad ee gaarka ah, iyo cilmi-baarayaasha agabka horumarsan ee u baahan tayada joogtada ah ee dalbanaya isku dhafka organosilicon iyo hababka polymerization.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.
