Saliidaha saldhigga ah iyo waxyaabaha lagu daro ee saliidda duuban
Ester-ka gaarka ah wuxuu yareeyaa is-jiidjiidka aagga tolitaanka wuxuuna xaqiijiyaa nadaafadda soo laabashada.
Iska yaree budada birta iyo xidhashada dusha birta, ka hortag qallafsanaanta dusha sare.
Ester-ka Complex wuxuu bixiyaa saliid aad u fiican.
Deegaanka shaqada oo ka caafimaad badan.Qaylada hoose, shoogga yar, yaraynta isticmaalka, kaydi tamarta, yaraynta kharashka la ilaaliyo iyo nolosha adeeg dheer -
Wax-ku-darka dufan ee dareeraha shaqada birta
Taxanaha Ester ee dareeraha shaqada birta:
Monoesters, diesters iyo polyol esters ee acids dufanka leh ee loo isticmaalo dareeraha birta salida ee saliidda si loo yareeyo xiisadda dusha sare
inta u dhaxaysa saliida iyo birta, waxay bixiyaan xoog fiiqan oo wanaagsan.Dheecaan biyo-ku-salaysan birta, waxay u isticmaashay milaan saliid waxayna keentaa EP iyo ka-saareyaasha daxalka.
Waxyaabaha saliidda lagu daro ee matoorada:
Esters-ka polymeric gaar ah oo leh sifooyin samaynta filim heer sare ah ayaa bixiya mishiinka iyo gudbinta saliida isku dhafka ah ee hagaajinta waxtarka.

Saliida shaqada birta lagu daro
Dhexdhexaadinta deminta PAG:
Viscosity sare ee biyaha ku milmay PAG, xakamee qalooca cabbirrada qaboojinta adoo hagaajinaya cufka molarka iyo xoojinta polymer.
Dareeraha saafiga ah iyo midabka iftiinka ayaa ka dhigaya sheyga ugu dambeeya ee caddaynta iyo hufnaanta.
Hanti nadiifin heer sare ah, oo ku habboon in la nadiifiyo qalabka shaqada ka dib marka la demiyo.
Wax lagu daro saliid deminta:Polymer-molecular-sare wuxuu bixiyaa dhalaal aad u fiican oo ah workpiece la demiyay.
Dareeraha viscous ee hufan, uma baahna kuleyl, fududahay in la isticmaalo.
Barta toosan ee sare, nolosha dheer, qiyaasta hoose, ku habboon saliid dhalaalaysa, saliidda deminta xawaaraha, talo gaar ah in loo isticmaalo saliid deminta isothermal. -
Saliida saldhiga ee matoorada baabuurta iyo gudbinta
PAG ee matoorada baabuurta iyo gudbinta
Sida saldhigga saliida matoorka synthetic, PAG waxay leedahay kala firidhsan heersare ah, nadiif ah oo bixisa xasillooni heerkul sare oo heer sare ah, saliid iyo dareere heerkul hooseeya.
Isku dhafka hoose ee iskuxiran wuxuu wanaajin karaa dhaqaalaha shidaalka wuxuuna si fiican u ilaalin karaa khilaafka.
Ester synthetic ee matoorada baabuurta iyo gudbintaGebi ahaanba esterification polyol ester iyo diesters, daahir sare.
Ku milmi dufanka saliidda macdanta iyo PAO heerkul sarreeya, yaree dhigaalka iyo filimka.
CCS heerkul hoose oo aad u wanaagsan ayaa wanaajin kara awoodda bilowga heerkulka hooseeya.
Xasiloonida ka-hortagga oksaydhka ee aadka u wanaagsan iyo kala firdhinta nadiifka ah waxay keenaysaa nolol adeeg oo dheer. -
Saliidda saldhigga ah ee Dufanka
Saliidda saldhigga ah ee dufanka:
Ester nadiif ah oo sarreeya, Saliid Wanaagsan iyo milmayn
Waxyeelo la'aan iyo dib u cusboonaysiin, Buuxi heerka xidhiidhka cuntada
Qaadashada heerkul aad u daran, hoos u dhig luminta uumiga heerkul sare oo ha ku barafoobin heerkul hoose
PAG kala duwan ayaa loo isticmaali karaa sidii saliid saleedka dufanka si kor loogu qaado saliidda iyo hantida heerkulka hoose. -
Saliidda saldhigga saliidda silsiladda heerkulka sare
PAG ee saliidda silsiladda heerkulka sare:
Heerkulka ku habboon wuxuu gaari karaa 220 ℃, oo si ballaaran loogu isticmaalo warshadaha baabuurta.
Esters synthetic ee saliidda silsiladda heerkulka sare:Isticmaal alkolada dipentyl ester iyo polybasic acid ester sida saliidda saldhigga, oo loo isticmaalo inta u dhaxaysa 250-300 ℃.
