wax ka beddelka miisaanka molecular
hantida kiimikada
Waxay leedahay noocyo badan, oo ay ku jiraan aliphatic thiols, xanthate disulfide, polyphenols, baaruud, halides iyo xeryahooda nitroso, waxaana si weyn loogu isticmaalaa falcelinta polymerization ee xorta ah.
Soo bandhigida alaabta iyo sifooyinka
Xakamaynta miisaanka molecular waxa loola jeedaa ku-darka qadar yar oo walax ah oo leh wareejinta silsiladda weyn ee joogtada ah ee nidaamka polymerization.Sababtoo ah awoodda wareejinta silsiladda ayaa si gaar ah u xoog badan, kaliya qadar yar oo ku dar ah ayaa si weyn u dhimi kara miisaanka kelli, laakiin sidoo kale iyada oo la hagaajinayo qiyaasta si loo xakameeyo miisaanka kelliyada, sidaas darteed wakiilka wareejinta silsiladda noocan oo kale ah ayaa sidoo kale loo yaqaannaa xakamaynta miisaanka molecular.Tusaale ahaan, dodecyl thiols ayaa inta badan loo isticmaalaa sidii hagayaasha miisaanka molecular ee wax soo saarka fiber acrylic.Xakamaynta miisaanka molecular waxa loola jeedaa walaxda xakamayn karta miisaanka molecular ee polymerka oo yareeya silsiladda silsiladda polymer.Dabeecaddeeda ayaa ah in joogtada ah ee wareejinta silsiladda ay aad u weyn tahay, sidaas darteed qadar yar ayaa si wax ku ool ah u yareyn kara miisaanka kelli ee polymer, kaas oo ku habboon ka-shaqeynta ka dib iyo codsiga polymer.Regulator gaaban, oo sidoo kale loo yaqaano polymerization regulator
isticmaal
Polymerization emulsion ee caag synthetic, sida caadiga ah isticmaal thiols aliphatic (sida dodecarbothiol, CH3 (CH2) 11SH) iyo disulphide diisopropyl xanthogenate (taas oo ah, maamulaha butyl) C8H14O2S4, gaar ahaan aliphatic thiols, oo dedejiya falcelinta;Isku-dubbaridka olefin polymerization, hydrogen waxa loo istcimaalaa habeeyaha miisaanka molecular.
xirmo iyo gaadiid
B. Alaabtan waxaa loo isticmaali karaa,25KG, 200KG,1000KG, foosto.
C. Ku kaydi meel qabow, qalalan oo hawo leh oo gudaha ah.Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor intaan la isticmaalin.
D. Alaabtan waa in si fiican loo xiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xooggan iyo aashitada, roobka iyo wasakhda kale ee isku darka.
