Cayayaanka Dhexdhexaadiya Tetrahydrophthalic Anhydride

Astaamaha tetrahydrophthalic anhydride:
Tetrahydrophthalic Anhydride waa mid adag, aan midab lahayn oo hufan. Waa mid aan lagu milmi karin biyaha heerkulka qolka, laakiin waxay ku milmaan dareerayaasha organic sida khamriga iyo ethers.
Tetrahydrophthalic Anhydride waxay leedahay bar dhalaalaysa 124-125°C iyo barta karkarinta 315°C. Waxay ku xasilloon tahay heerkul sarreeya.
Tetrahydrophthalic Anhydride waxay leedahay xasillooni gaar ah, laakiin falcelinta burburka iyo oksaydhisku waxay ku dhici kartaa heerkul sare, iftiinka qorraxda ama soo-gaadhista ogsijiinta.
Isticmaalka tetrahydrophthalic anhydride:
1. Tetrahydrophthalic Anhydride waxaa si weyn loogu isticmaalaa isku-dhafka dabiiciga ah, waa dhexdhexaad kiimiko oo muhiim ah, oo guud ahaan loo isticmaalo soosaarka alkyd resins, resins polyester-ka aan saturated iyo dahaarka.
2. Tetrahydrophthalic Anhydride waxaa loo isticmaali karaa in lagu soo saaro anhydrides, esters, ethers iyo xeryahooda kale.
3. Tetrahydrophthalic Anhydride waxaa loo isticmaali karaa sida xasiliyayaal, kicinta, balaastiga, midabaynta iyo alaabta ceeriin ee alaabta polymer.
4. Tetrahydrophthalic Anhydride waxa loo isticmaali karaa sidii wakiilka daawaynta resin epoxy, sunta cayayaanka, nidaamiyaha vulcanization iyo surfactant.
5. Tetrahydrophthalic Anhydride waxaa loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay soo saarista suufka polyesterka ee aan saturated, inta badan waxaa loo isticmaalaa si loo hagaajiyo waxqabadka hawo-qallajinta ee xabagta, gaar ahaan loo isticmaalo soo saarista dufanka heerka sare ah iyo daboolka qallajinta hawada.
6. Tetrahydrophthalic Anhydride waxa loo isticmaali karaa sidii wax ka beddelka xabagta alkyd, wakiilka daawaynta resin epoxy, xabagta polyester-ka aan saturated lahayn, sunta cayayaanka iyo alaabta ceeriin ee dawooyinka.
Habka Diyaarinta:
Diyaarinta Tetrahydrophthalic Anhydride guud ahaan waxaa lagu helaa esterification of cis-1,2,3,6-tetrahydroxyphthalic acid.
Hababka gaarka ah waxaa ka mid ah in lagu daro wakiilka emsterifying adkaha ama xalka, ka falcelinta kulaylka iyo nadiifinta nadiifinta.
Macluumaadka Badbaadada:
1. Tetrahydrophthalic Anhydride guud ahaan waa walax sun ah oo hooseysa marka loo eego xaaladaha caadiga ah ee isticmaalka.
2. Inta lagu jiro qaliinka, ka taxadar inaad iska ilaaliso taabashada maqaarka iyo indhaha iskuna day inaad ilaaliso jawi hawo fiican leh.
3. Inta lagu jiro kaydinta iyo gaadiidka, iska ilaali inaad la xiriirto walxaha oksijiinta, asiidhyada xooggan iyo walxaha kale, iyo sidoo kale fiiro gaar ah u leh ilaalinta qoyaanka iyo ka hortagga dabka.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dajiso ama dhoofiso waxa ka mid ah.

( 1 ) Polymers: Polymersation waa habka ay unugyada soo noqnoqda ee ka samaysan polymer ay si wadajir ah ugu xiran yihiin bonds covalent. Polymers waxay ka jiri karaan gobolo kala duwan iyadoo ku xiran wajiga, qaabka iyo habeynta silsiladahooda molecular. Labada dawladood ee ugu waaweyn waa amorphous iyo crystalline. Polymers inta badan waxay ku jiraan qaab semi-crystalline ah kaas oo wejiyada amorphous iyo crystalline ay wada nool yihiin.

(2) Kaaliyeyaasha iyo Kaaliyeyaasha : Kaaliyaha waa qaybta firfircoon ee runtii u shaqeysa sidii kicin oo yaraynaysa tamarta firfircoonida ee falcelinta. Waxyaalaha lagu daro, dhinaca kale, waa qaybo kaabayaal ah, ama wax-ku-darka qaab-dhismeedka ama qalabka elektarooniga ah, kuwaas oo hagaajin kara xasiloonida kicinta, halka kuwa elektaroonigga ah ay wax ka bedeli karaan sifooyinka elektaroonigga ah ee kicinta .
