kev hloov pauv qhov hnyav molecular
cov khoom siv tshuaj lom neeg
Nws muaj ntau hom, suav nrog aliphatic thiols, xanthate disulfide, polyphenols, sulfur, halides thiab nitroso compounds, thiab yog siv dav hauv cov tshuaj tiv thaiv dawb radical polymerization.
Kev taw qhia txog khoom thiab nta
Tus tswj qhov hnyav molecular yog hais txog kev ntxiv me me ntawm cov khoom siv nrog cov saw hlau loj hloov pauv tas mus li hauv lub kaw lus polymerization. Vim tias lub peev xwm hloov pauv saw hlau muaj zog heev, tsuas yog me me ntawm kev ntxiv tuaj yeem txo qhov hnyav molecular, tab sis kuj los ntawm kev kho cov koob tshuaj kom tswj tau qhov hnyav molecular, yog li hom kev hloov pauv saw hlau no kuj hu ua tus tswj qhov hnyav molecular. Piv txwv li, dodecyl thiols feem ntau siv los ua tus tswj qhov hnyav molecular hauv kev tsim cov fiber acrylic. Tus tswj qhov hnyav molecular yog hais txog cov khoom uas tuaj yeem tswj qhov hnyav molecular ntawm polymer thiab txo qhov ceg ntawm cov saw hlau ntawm polymer. Nws tus yam ntxwv yog tias qhov hloov pauv saw hlau tas mus li yog loj heev, yog li me me tuaj yeem txo qhov hnyav molecular ntawm polymer, uas yog qhov zoo rau kev ua tiav tom qab thiab kev siv polymer. Tus tswj luv luv, tseem hu ua tus tswj polymerization.
siv
Hauv kev ua cov roj hmab hluavtaws emulsion polymerization, feem ntau siv aliphatic thiols (xws li dodecarbothiol, CH3 (CH2) 11SH) thiab disulphide diisopropyl xanthogenate (uas yog, tus tswj butyl) C8H14O2S4, tshwj xeeb tshaj yog aliphatic thiols, thiab ua kom cov tshuaj tiv thaiv sai dua; Hauv olefin coordination polymerization, hydrogen yog siv ua tus tswj qhov hnyav molecular.
pob khoom thiab kev thauj mus los
B. Cov khoom no siv tau, 25KG, 200KG, 1000KG, thoob.
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
