Cov dej solubility ntawm Sulfur Black

Cov dej solubility ntawm Sulfur Black feem ntau cuam tshuam los ntawm plaub yam tseem ceeb: nws tus kheej cov qauv tshuaj, txheej txheem kev npaj, kev hloov kho sab nraud, thiab daim ntawv thov ib puag ncig. Raws li hom sulfur dye, nws muaj cov dej tsis zoo hauv cov dej solubility thiab xav tau kev kho tshwj xeeb los txhim kho cov dej solubility rau kev siv tswv yim.

Nyob rau hauv cov nqe lus ntawm cov qauv tshuaj, cov pob txha molecular ntawm Sulfur Black yog nruab nrab ntawm cov nplhaib uas muaj ntxhiab txuas nrog cov sulfur bonds los tsim cov qauv macromolecular, uas tsis muaj zog hydrophilic pawg inherently, ua rau cov dej tsis muaj zog yooj yim solubility. Qhov siab dua qhov crosslinking℃ntawm cov saw hlau molecular thiab qhov loj dua qhov hnyav molecular, cov dej solubility yuav phem dua. Ib qho me me ntawm cov seem nruab nrab nrog cov pab pawg hydrophilic thaum lub sijhawm npaj tuaj yeem txhim kho nws cov dej solubility me ntsis, tab sis qhov cuam tshuam tag nrho yog txwv.

Cov txheej txheem kev npaj yog qhov tseem ceeb ntawm kev txiav txim siab cov dej solubility ntawm Sulfur Black, nrog cov tub ntxhais pw hauv kev tswj cov tshuaj tiv thaiv vulcanization. Qhov ntau npaum ntawm leej faj, qhov ntsuas kub thiab lub sij hawm thaum lub sij hawm vulcanization ncaj qha cuam tshuam qhov ntau thiab crosslinking℃ntawm sulfur bonds. Cov tshuaj sulfur ntau dhau, qhov kub thiab txias ntau dhau los yog lub sijhawm ua rau cov tshuaj tiv thaiv ntev yuav ua rau kom nruj dua molecular crosslinking thiab txo qis ntawm cov dej solubility. Lub caij no, kev tshaj tawm - txheej txheem ziab ziab kuj tseem ua rau muaj kev cuam tshuam: siab- kub ziab yuav ua rau molecular agglomeration, uas txo cov dispersibility thaum lub sij hawm tom qab dissolution thiab indirectly cuam tshuam cov dej solubility nyhuv.

Kev hloov kho sab nraud yog ib txoj hauv kev zoo los hloov pauv cov dej solubility ntawm Sulfur Black, uas kuj yog txoj hauv kev tseem ceeb los txhim kho nws cov dej solubility. Ib qho kev kho yog txo qis, siv cov tshuaj txo qis xws li sodium hydrosulfite los txo cov sulfur bonds hauv Sulfur Black molecules rau hauv pawg hydrophilic xws li mercapto pawg, hloov mus rau hauv dej - soluble leuco daim ntawv kom tau raws li cov cai ntawm daim ntawv thov dyeing. Tsis tas li ntawd, kev hloov kho surfactant thiab kev hloov kho sulfonation tuaj yeem qhia cov khoom siv hydrophilic ntawm cov molecular nto los txhim kho nws cov dispersion thiab dissolution muaj peev xwm nyob rau hauv dej, thaum lub unmodified raw Sulfur Black hmoov yog yuav luag insoluble nyob rau hauv dej.

Cov xwm txheej ib puag ncig thaum lub sijhawm thov yuav cuam tshuam rau kev ua haujlwm ntawm dej solubility. Ua ntej yog tus nqi pH ntawm cov dej zoo: qhov txo qis leuco daim ntawv ntawm Sulfur Black yog qhov ruaj khov thiab muaj cov dej zoo dua solubility hauv alkaline ib puag ncig, thaum acidic ib puag ncig yog nquag ua rau oxidation thiab nag lossis daus ntawm leuco daim ntawv, yog li txo cov dej solubility. Qhov thib ob yog dej kub: qhov tsim nyog nce dej kub tuaj yeem ua rau kom tawg ntawm Sulfur Black hais thiab pab txhim kho kev ua kom tiav, tab sis kub siab heev yuav ua rau kom cov decomposition ntawm txo cov neeg ua hauj lwm thiab es tsis txhob cuam tshuam cov stability ntawm dej solubility. Tsis tas li ntawd, cov ntsiab lus electrolyte hauv dej kuj tseem ceeb, vim tias calcium thiab magnesium ions hauv cov dej nyuaj yuav ua ke nrog Sulfur Black leuco daim ntawv los ua cov dej nag, ntxiv txo nws cov dej solubility thiab dispersibility.

Tsis tas li ntawd, qhov loj me ntawm Sulfur Black muaj cov txiaj ntsig pabcuam. Qhov zoo dua cov khoom yog hauv av, qhov loj dua qhov tshwj xeeb ntawm thaj chaw yuav yog, uas ua rau thaj chaw sib cuag nrog dej thiab ua kom lub cev tawg sai sai, tab sis qhov no tsuas yog cuam tshuam rau kev ua kom tiav tsis muaj kev hloov pauv ntawm qhov txwv ntawm nws cov dej solubility.ground, qhov loj dua qhov tshwj xeeb ntawm thaj chaw yuav yog, uas ua rau thaj chaw sib cuag nrog dej thiab ua kom lub zog tawg ntawm qhov kev cuam tshuam tsuas yog nyob rau sab saud, tab sis qhov no yog qhov loj dua. dej solubility.
