Fasalka Warshadaha ee Tayada Sare ee Kaalshiyam Acetate Budada Cad

Macluumaadka Alaabta

Calcium Acetate waa cusbada acetate ee kaalshiyamka leh caanaha kiimikada C4H6CaO4. Magaca guud ee calcium acetate waa calcium acetate. Anhydrous calcium acetate waa mid aad u hygroscopic, sidaas darteed waa caadi in la helo calcium acetate sida monohydrate ah (Ca (CH3COO) 2.H2O, CAS [5743-26-0]).
Diyaarinta
1. Waxaa lagu helaa iyadoo la nadiifinayo pyroligneous acid (alwaax acetic acid) oo leh calcium hydroxide, qaadashada shaandhaynta iyo uumi-baxa, oo dib u soo celisa;
2. Waxaa laga helay falcelinta acetic acid la calcium hydroxide ama calcium carbonate, sifeeyo, xoog iyo la qaboojiyey si aad u hesho milix dihydrate (kristal midab lahayn), kuleyl ilaa 84 ℃ si aad u hesho milix monohydrate (kristal midab lahayn), kuleyl ilaa 100 ℃ si aad u hesho cusbo anhydrous;
3. Qolfoof sida alaabta ceeriin, ka dib nadiifinta, burburinta, qalajinta 1h, lagu dubay 900 ~ l000 ℃ 2h, ka dibna ku dar biyo si aad u sameyso 1.3 ~ 1.5mol / L oo caano lime ah. Kadibna waxaa lagu dhex milmay acetic acid ilaa la caddeeyo, la sifeeyo, sifaynta ayaa la ururiyey, ugu dambeyntiina la qalajiyey 120 ~ 140 ° C si loo helo badeecada la dhammeeyey oo leh 91.28% wax soo saar.
In 20% xal acetic acid ku dar kalsiyum carbonate budada, ilaa ay mar dambe baxsadaan CO2 gaaska, ka dibna ku dar qadar yar oo calcium carbonate ah, kululaynta 80 ℃ falcelinta 2 ~ 3h sifeeyo kulaylka biyaha qubeyska iyo fiirsashada, isla mar ahaantaana ku dar qadar yar oo ah 80% acetic acid, taas oo ah, roobka ee calcium acetate monohydrate, ugu dambeyntii 6 premihydrate. ~ 70 ℃ hoos qalajinta alaabta la dhammeeyey. Isla'egta kiimikada waa sida soo socota:
2CH3COOH+CaCO3→(CH3COO)2Ca+H2O+CO2↑
4. Habka calcium acetate anhydrous: ku dar kaalshiyam kaarboonayt oo budada la safeeyey biyaha, walaaq ganaax, oo ku dar qadar yar oo glacial acetic acid marxaladaha. Dhammaadka falcelinta, shaandheyntu waxay ku urursan tahay qubeyska biyaha, iyo adkaha cad, ie anhydrous calcium acetate, ayaa laga soo dajiyay filtarrada viscous;
5. Ku dar 100g oo kaalshiyam carbonate ah 500-700ml oo biyo ah si aad u hesho joojinta. Ku dar 110mL glacial acetic acid qadar yar oo walaaqaya mid mid, iyo gaasta kaarboon dioxide waa la sii daayay. Ka dib marka la dhammeeyo falcelinta, sifeynta, shaandhaynta biyaha qubeyska si aad u foojignaato ilaa xalku noqdo mid dhumuc weyn, laga bilaabo dareeraha qaro weyn oo soo degay badeecada cad, taas oo ah, calcium acetate anhydrous. Haddii khamriga hooyadu ka tago wakhti dheer, adkaha adag waa calcium acetate monohydrate.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Daaweynta Biyaha: Hababka hysical P sidoo kale waxaa ka mid ah roobka, waa in la ogolaado wasakhda cufjiitada gaarka ah ee ka yar inay sabeeyaan biyaha dusheeda si ay uga kalluumaystaan, ama wasakhda roobabka cufisjiidadka gaarka ah ee hoose, ka dibna la helo. Habka kiimikooyinka waa in la isticmaalo noocyo kala duwan oo kiimikooyin ah oo ku jira wasakhda biyaha galay walxaha waxyeellada yar, ama wasakhda la ururiyey, taariikhda ugu dheer ee hababka daaweynta kiimikada waa in la tixgeliyaa in lagu daro biyaha leh alum, ururinta wasakhda biyaha, mugga ayaa noqda mid weyn, waxaa loo isticmaali karaa sifeynta, ka saarista wasakhda.

(2) Alaabooyinka Caadiga ah : Rabberku waa elastomer heerkulbeeye kul-milmi leh, halka balaastikada ay yihiin meel-qabow kulul-milmi kara. Caag sababtoo ah noocyada kala duwan ee jirka vulcanizate, qaabaynta iyo daaweynta heerkulka heerkulka, waxaa jira farqi weyn, iyo xitaa isbeddelka cimilada awgeed, heerkulka gudaha iyo huurka ayaa saameeya. Sidaa darteed, xaaladaha wax soo saarka ee alaabooyinka caaggu waxay u baahan yihiin in si dhexdhexaad ah loo hagaajiyo wakhti kasta, haddii kale, waxay soo saari kartaa kala duwanaansho tayada alaabta.

(3)Catalysts and Auxiliaries: Guud ahaan hadalka, kicinta waa walax ka qaybqaata koorsada dhexdhexaadka ah ee falcelinta kiimikada waxayna si door ah u bedeli kartaa heerka falcelinta kiimikada, iyada oo tirada iyo hantida kiimikada ay asal ahaan aan isbeddelin ka hor iyo ka dib falcelinta. Caadiyan, kicinta waxa ay dedejisaa falcelinta kiimikaad, si ay falcelintu u gaadho isu dheelitirka kiimikaad sida ugu dhakhsaha badan waxa loogu yeedhaa saamaynta catalytic, laakiin ma beddesho dheellitirka falcelinta.

Waxyaabaha lagu daro waa noocyo kala duwan oo kiimikooyin caawiya kuwaas oo u baahan in lagu daro inta lagu jiro wax soo saarka ama habaynta alaabta iyo alaabta qaarkood si kor loogu qaado habka wax soo saarka iyo kor u qaadida waxqabadka sheyga looga baahan yahay noocyada kala duwan ee kiimikooyinka caawiya.
