Kupanga ufa wobwezeretsedwa ndi polima ndi njira yovuta yokhudza magawo angapo, iliyonse yomwe imafunikira kuti mukwaniritse zomwe mukufuna.
1. Kuyambitsa kusinthidwa polima
A. Tanthauzo ndi kugwiritsa ntchito
Mapaketi otsetsereka a polimate ali ndi ma polymer polymer omwe amatha kubalalika mosavuta m'madzi kuti apange emulsions yokhazikika. Ufa uwu umagwiritsidwa ntchito kwambiri popanga zomanga monga matope, zomatira ndi zopukutira monga zimathandizira mphamvu, zomatira komanso kusinthasintha kwa zinthu izi.
B. Kupangidwa koyambirira
Zosakaniza zazikulu zobwezeretsedwanso polima pollder ikuphatikiza:
Polymer Beer: The Polymer Beer ndi chinthu chachikulu ndipo nthawi zambiri nthawi zambiri zimakhala zotupa za vinyl acetate ndi ethylene (vae) kapena polymer yoyenera. Izi zimapereka kusintha kotsiriza ndi kutsatira.
Colloid Colloid: Onjezani okhazikika kapena zoteteza ma colloids kuti mupewe ma polymer tinthu tambiri kuchokera kuzolowera posungira.
Zowonjezera: Zowonjezera zosiyanasiyana, monga zodekha, ma pulasitiki, ndi okuzira, zitha kuphatikizidwa kuti zithetse zomwe ufa.
2. Kupanga
A. Emulsion Polymerization
Kusankhidwa kwa Motomeer: Gawo loyamba limaphatikizapo kusankha molomers yoyenera pakuchita kwa polymerization, nthawi zambiri ma vinyl acetate ndi ethylene.
Emulsization: Kugwiritsa ntchito okonda kuyendetsa moomemers mumadzi kuti apange emulsion.
Polymerization: Woyambitsa amawonjezeredwa ku emulsion kuti ayambitse ma polymerization. Tinthu tating'onoting'ono timakula ndipo pamapeto pake zimapanga mphamvu polymer.
Zotsatira-machitidwe: Njira zowonjezera monga kuwongolera PH ndi kutentha ndizovuta kuti zithe kukwaniritsa zomwe mukufuna.
B. Kuyanima
Emulsion ndende: Kungoonjeza polima kwa emulsion ku zinthu zina zolimba kuti zisafowa.
Kuyanika kwa Spira: emu yokhazikika imavomerezedwa kukhala m'malo abwino ndikudziwitsa chipinda chamatenthedwe. Madziwo amatuluka, kusiya tinthu tating'onoting'ono.
Kuwongolera kukula kwa tinthu: Konzani magawo osiyanasiyana kuphatikiza kuchuluka kwa chakudya, kutentha komwa ndi kapangidwe kaphokoso kowongolera tinthu tating'onoting'ono.
C. Powder Post-proces
Kuonjezera zoteteza: Colloid yoteteza nthawi zambiri imawonjezeredwa kwa ufa kuti zilepheretse kutengapo gawo ndikusinthanso.
Zowonjezera: Zowonjezera zina zimatha kuyambitsa gawo ili kuti liziwonjezera zomwe ufa.
3. Kuwongolera Kwabwino ndi Kuyesa
A. Kusanthula Kwa tinthu tating'onoting'ono
Maluse osiyanasiyana: Njira zosiyanasiyana za laser zimagwiritsidwa ntchito poyesa kugawa kukula kwa tinthu tambiri obwezeretsedwa.
Kusanthula kwa ma microscopy: Kusanthula kwa microscopic kumatha kupereka luntha mu tinthu morphology ndi zovuta zilizonse zosokoneza.
B. Kuyesedwa
Kuyesa kwamadzi: Sakanizani ufa ndi madzi kuti muone luso lopanga emulsion.
Kuyeserera kowoneka: Konzani mawonekedwe a obwezeretsedwawo, kuphatikizapo chilichonse kapena ma applomerates.
C. Kusanthula kwa mankhwala
Kuphatikizidwa kwa polymer: Maluso monga masinthidwe anayi omwe aperekedwa Spectroscopy (FTIR) amagwiritsidwa ntchito posanthula mankhwala a ma polity.
Zotsalira zotsalira: Gwiritsani ntchito ma chromatotography kapena njira zina kuti mudziwe kukhalapo kwa monomers iliyonse yotsalira.
4 .. Zovuta ndi Maganizo
A. Zovuta za chilengedwe
Kusankha kwazinthu: Kusankha zachilengedwe kukhala kosangalatsa komanso zinthu zopangira kungachepetse kusintha kwa chilengedwe pazopanga.
Kugwiritsa ntchito mphamvu: Kukhazikitsa mphamvu kugwiritsa ntchito mphamvu, makamaka pakuwuma, kumathandizira kukhazikika.
B. Ntchito
Kuphatikizika kwa polymer: kusankha kwa polymer ndipo kapangidwe kake kumakhudzanso katundu wa ma polimature polima.
Kusunga: Kuchulukitsa Colloid yoteteza ndikofunikira kuti muchepetse ufa wosungira nthawi yosungirako.
Mapeto
Kupanga ufa wobwezeretsa polima kumaphatikizapo kuphatikiza kovuta kwa emulsion polymerization, utsi wa utsi ndi njira yosinthira. Njira Zowongolera Zowongolera, kuphatikiza kukula kwa tinthu ndikuyesanso, ndizofunikira kwambiri kuti malonda akwaniritse zomwe zikufunika. Kuganizira zachilengedwe komanso kugwira ntchito kumapangitsa kuti chitukuko ndi kugwiritsa ntchito ufa wobwezeretsedwa m'mafakitale osiyanasiyana.
