Habka polymerization-ka tooska ah ee plasma

Habka polymerization-ka tooska ah ee plasma

Habka loo sameeyo polymerization-ka Plasma waa mid fudud labada qalab ee polymerization-ka gudaha ee elektroodka iyo qalabka polymerization-ka elektroodka dibadda, laakiin xulashada parameter-ka ayaa aad muhiim ugu ah polymerization-ka Plasma, sababtoo ah parameters-ku waxay saameyn weyn ku leeyihiin qaab-dhismeedka iyo waxqabadka filimada polymer inta lagu jiro polymerization-ka Plasma.

Tallaabooyinka hawlgalka ee polymerization-ka tooska ah ee plasma waa sida soo socota:

(1) Nadiifinta faakiyuumka

Faakuumka asalka ah ee polymerization-ka marka la eego xaaladaha faakuumka waa in lagu shubaa 1.3 × 10-1Pa. Falgallada polymerization-ka ee u baahan shuruudo gaar ah si loo xakameeyo heerka oksijiinta ama nitrogen, baahida faakuumka asalka ah ayaa xitaa ka sarreysa.

(2) Monomer-ka falcelinta dallacaadda ama gaaska isku dhafan ee gaaska side iyo monomer-ka

Heerka faakuumka waa 13-130Pa. Si loo sameeyo polymerization-ka Balaasmaha ee u baahan shaqada, habka xakamaynta socodka ee habboon iyo heerka socodka waa in la doortaa, guud ahaan 10.100mL/daqiiqo. Balaasmaha, molecules-ka monomer-ka waa la ioneeyaa oo kala firdhiyaa iyadoo la duqaynayo walxaha firfircoon, taasoo keenta walxo firfircoon sida ion iyo hiddo-wadeyaal firfircoon. Walxaha firfircoon ee Balaasmaha uu kiciyo waxay mari karaan polymerization-ka Balaasmaha marka la isku xidho wejiga gaaska iyo wejiga adag. Monomer-ku waa isha horudhaca polymerization-ka Balaasmaha, gaaska falgalka iyo monomer-ka ee la geliyo waa inay lahaadaan daahirnimo gaar ah.

(3) Xulashada korontada kicinta

Balaasma waxaa lagu soo saari karaa iyadoo la adeegsanayo ilaha korontada ee DC, kuwa sare, RF, ama microwave-ka si loo bixiyo jawi balaasma ah oo lagu buufin karo. Xulashada korontada waxaa lagu go'aamiyaa iyadoo lagu saleynayo shuruudaha qaab-dhismeedka iyo waxqabadka polymer-ka.

(4) Xulashada qaabka sii deynta

Shuruudaha polymer-ka, polymerization-ka Plasma wuxuu dooran karaa laba qaab oo sii deyn ah: sii deyn joogto ah ama sii deyn garaaca wadnaha.

(5) Xulashada xuduudaha sii deynta

Marka la sameynayo polymerization-ka Balaasmaha, xuduudaha dheecaanka waa in laga tixgeliyaa xuduudaha balaasmaha, sifooyinka polymer-ka iyo shuruudaha qaab-dhismeedka. Cabbirka awoodda la adeegsaday inta lagu jiro polymerization-ka waxaa lagu go'aamiyaa mugga qolka faakiyuumka, cabbirka elektroodka, heerka socodka monomer-ka iyo qaab-dhismeedka, heerka polymerization-ka, iyo qaab-dhismeedka iyo waxqabadka polymer-ka. Tusaale ahaan, haddii mugga qolka falcelinta uu yahay 1L oo RF-ga Balaasmaha la qaato, awoodda dheecaanka waxay ku jiri doontaa inta u dhaxaysa 10 ~ 30W. Xaaladaha noocaas ah, balaasmaha la soo saaray ayaa isku dari kara si ay u sameeyaan filim khafiif ah oo ku yaal dusha sare ee shaqada. Heerka koritaanka filimka polymerization-ka Balaasmaha wuu kala duwan yahay iyadoo la eegayo korontada, nooca monomer-ka iyo heerka socodka, iyo xaaladaha habka. Guud ahaan, heerka koritaanka waa 100nm/min~1um/daqiiqo.

(6) Cabbiraadda halbeegga ee Polymerization-ka Balaasmaha

Xuduudaha balaasmaha iyo xuduudaha habka loo cabbirayo polymerization-ka balaasmaha waxaa ka mid ah: danabka sii deynta, qulqulka sii deynta, soo noqnoqoshada sii deynta, heerkulka elektrooniga, cufnaanta, nooca kooxda falgalka iyo xoojinta, iwm.
