wax ka beddelka miisaanka molecular-ka

hantida kiimikada

Waxay leedahay noocyo badan, oo ay ku jiraan aliphatic thiols, xanthate disulfide, polyphenols, sulfur, halides iyo nitroso compounds, waxaana si weyn loogu isticmaalaa falcelinta polymerization-ka xorta ah.

Soo bandhigidda badeecada iyo sifooyinka

Xakameeyaha miisaanka molecular-ka waxa uu tilmaamayaa ku darista xaddi yar oo walax ah oo leh joogto wareejin silsilad weyn ah oo ku jirta nidaamka polymerization-ka. Maadaama awoodda wareejinta silsiladdu ay si gaar ah u xooggan tahay, xaddi yar oo lagu daray ayaa si weyn u yareyn kara miisaanka molecular-ka, laakiin sidoo kale iyadoo la hagaajinayo qiyaasta si loo xakameeyo miisaanka molecular-ka, sidaa darteed noocan wakiilka wareejinta silsiladda waxaa sidoo kale loo yaqaan xakameeyaha miisaanka molecular-ka. Tusaale ahaan, dodecyl thiols waxaa badanaa loo isticmaalaa sidii xakameeyayaasha miisaanka molecular-ka ee wax soo saarka fiber-ka acrylic. Xakameeyaha miisaanka molecular-ka waxa uu tilmaamayaa walaxda xakamayn karta miisaanka molecular-ka ee polymer-ka oo yarayn karta laanta silsiladda ee polymer-ka. Astaamaheeda ayaa ah in joogtada wareejinta silsiladdu ay aad u weyn tahay, sidaa darteed xaddi yar ayaa si wax ku ool ah u yareyn kara miisaanka molecular-ka ee polymer-ka, kaas oo ku habboon ka dib-u-habeynta iyo codsiga polymer-ka. Xakameeyaha gaaban, oo sidoo kale loo yaqaan xakameeyaha polymerization-ka.

isticmaal

Polymerization-ka emulsion-ka ee caagga synthetic-ga, badanaa waxaa loo isticmaalaa thiols-ka aliphatic (sida dodecarbothiol,CH3 (CH2) 11SH) iyo disulphide diisopropyl xanthogenate (taasi waa, regulator butyl)C8H14O2S4, gaar ahaan aliphatic thiols, waxayna dedejinaysaa falcelinta; Polymerization-ka isku-dubaridka olefin, hydrogen waxaa loo isticmaalaa sidii regulator miisaanka molecular-ka.

xirmada iyo gaadiidka

B. Badeecadan waxaa loo isticmaali karaa, 25KG, 200KG, 1000KG, foosto.
C. Ku kaydi meel qabow, qalalan oo hawo leh gudaha. Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor inta aan la isticmaalin.
D. Badeecadan waa in si fiican loo xiraa inta lagu jiro rarista si looga hortago qoyaanka, alkali iyo aashitada xooggan, roobka iyo wasakhda kale ee isku dhafan.
