isilungisi sobunzima bemolekyuli

ipropati yeekhemikhali

Ineentlobo ezininzi, kubandakanywa i-aliphatic thiols, i-xanthate disulfide, i-polyphenols, i-sulphur, i-halides kunye ne-nitroso compounds, kwaye isetyenziswa ngokubanzi kwi-free radical polymerization reactions.

Intshayelelo yemveliso kunye neempawu

I-molecular weight regulator ibhekisela ekongezwa kwexabiso elincinci lezinto eziphathekayo kunye nekhonkco enkulu yokudlulisa rhoqo kwinkqubo ye-polymerization.Ngenxa yokuba isakhono sokudlulisa ikhonkco lomelele ngakumbi, kuphela inani elincinci lokongezwa linokuthi linciphise kakhulu ubunzima bemolekyuli, kodwa nangokuhlengahlengisa idosi yokulawula ubunzima bemolekyuli, ngoko olu hlobo lwearhente yokudlulisa ikhonkco lukwabizwa ngokuba yi-molecular weight regulator.Ngokomzekelo, i-dodecyl thiols ihlala isetyenziswa njengabalawuli bobunzima bemolekyuli kwimveliso yefiber ye-acrylic.Isilawuli sobunzima bemolekyuli sibhekisa kwinto enokulawula ubunzima bemolekyuli yepolymer kunye nokunciphisa ikhonkco lekhonkco lepolymer.Isici sayo kukuba i-chain transfer transfer constant is very much, ngoko ke imali encinci inokunciphisa ngempumelelo i-molecular weight of polymer, ehambelana ne-post-processing kunye nokusetyenziswa kwepolymer.I-Regulator ngokufutshane, eyaziwa ngokuba yi-polymerization regulator

sebenzisa

Kwi-emulsion polymerization yerubha yokwenziwa, ngokuqhelekileyo isebenzisa i-aliphatic thiols (efana ne-dodecarbothiol, i-CH3 (CH2) 11SH) kunye ne-disulphide diisopropyl xanthogenate (oko kukuthi, i-butyl ye-regulator) C8H14O2S4, ngakumbi i-aliphatic thiols, kunye nokukhawuleza ukuphendula;Kwi-olefin coordination polymerization, i-hydrogen isetyenziswa njenge-molecular weight regulator.

iphakheji kunye nezithuthi

B. Le mveliso ingasetyenziswa, 25KG, 200KG, 1000KG, umphanda.
C. Gcina uvalelwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi.Imigqomo kufuneka ivalwe ngokuqinileyo emva kokusetyenziswa ngakunye phambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthutha ukukhusela umswakama, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ekuxubeni.
