Insoluble Sulfur, cov tshuaj molecular: Su, yog non-toxic, flammable daj hmoov, muaj npe vim tias nws yog insoluble hauv carbon disulfide. Nws yog tsim los ntawm thermal polymerization ntawm cov leej faj. Tus lej ntawm cov leej faj nyob hauv cov qauv molecular muaj npaum li 108 lossis ntau dua. Nws muaj cov viscoelasticity thiab molecular phaus faib ntawm polymer. Yog li ntawd, nws tseem hu ua elastic sulfur lossis polymerized sulfur. Nws yog ib qho inorganic polymer tshuaj raw khoom.
qhov zoo dua
1) Insoluble sulfur muaj nyob rau hauv cov roj hmab hauv lub xeev qhov chaw tawg, yog li cov roj hmab tsis tawg, muaj viscosity zoo, thiab tuaj yeem xyuas kom muaj qhov zoo ntawm cov khoom muag uas muaj xim.
2) Insoluble sulfur yog tusyees sib faib nrog cov roj hmab sib xyaw, tiv thaiv zoo tiv thaiv kev tsub zuj zuj ntawm cov leej faj, thiab txo qhov nyiam ntawm scorching thaum khaws cia ntawm cov roj hmab compound.
3) Cov tshuaj tua hluav taws xob tiv thaiv cov roj hmab tsis tuaj yeem tawg thaum lub sijhawm khaws cia thiab ua kom cov kev ua tiav ntawm cov roj hmab compound tsoos tsho. Tiv thaiv kom tsis muaj teeb meem ntawm cov khoom lag luam thiab cov pwm, thiab tshem tawm cov txheej txheej ntxiv rau kom kov yeej tawg paj, muab cov kev cai rau kev sib txuas ntau lawm.
4) Insoluble leej faj tiv thaiv cov roj hmab ntawm kev txav mus los hauv cov khaubncaws sab nraud povtseg uas nyob ib sab. Tshwj xeeb tshaj yog nyob rau hauv cov roj hmab txuas ntawm cov roj butadiene roj hmab thiab butyl roj hmab, kev nrawm nrawm ntawm cov leej faj tsis zoo yog ntau heev, uas tuaj yeem zam dhau tom qab ntxiv cov tshuaj tua kab.
5) Insoluble leej faj ua kom lub sijhawm kho tau zoo. Thaum nws nce mus txog qhov ntsuas kub vulcanization, nws muaj" ua rau qib", uas yog, cov saw depolymerization, uas ua kom nrawm rau qhov chaw vulcanization nrawm, txo qhov tsawg ntawm cov leej faj, thiab pab txhim kho kev laus ua haujlwm ntawm cov khoom.
siv
Insoluble leej faj, nws yog siv los ua cov qib siab ua kom muaj zog thiab ua tus sawv cev rau hauv kev lag luam roj hmab, thiab yog siv dav hauv kev tsim cov log tsheb thiab lwm cov khoom siv roj hmab, xws li cov log tsheb lub cev roj hmab, cov roj hmab cushion, cov roj hmab dawb ntawm cov roj hmab thiab cov hlua yas. Cov nplaum ntawm cov roj hmab thiab cov khoom siv xws li cov log tsheb, hoses, tapes, thiab lwm yam.
Ntawm cov roj hmab sib txuas, nws kuj tuaj yeem siv rau hauv cov khoom siv roj hmab xws li cov xaim hluav taws xob, cov roj hmab roj hmab, cov roj ntsaws ruaj ruaj, roj hmab khau, thiab lwm yam, thiab tseem muaj nyob rau hauv cov khoom siv roj hmab cov khoom muaj roj ntau ntau nrog leej faj. Vim tias cov kua hluav taws xob tsis tuaj yeem tuaj yeem ua rau cov meridian, cov hlau tsis xeb thiab cov roj hmab txhaws khov kho, zoo tiv thaiv cov roj hmab los tiv thaiv, thiab txhim kho cov kub tiv thaiv thiab hnav tsis kam ntawm lub log. Yog li no, insoluble leej faj yog qhov khoom siv tseem ceeb hauv cov log tsheb ntau lawm.
