Petroleum Jelly

Petroleum jelly yog ib nrab kua sib tov ntawm alkyl hydrocarbons los yog saturated hydrocarbons, tseem hu ua petrolatum, uas ua los ntawm fractional distillation ntawm roj av. Nws lub xeev yog nruab nrab ntawm cov khoom thiab cov kua nyob rau hauv chav tsev kub, thiab nws muaj peb xim xim av, daj thiab dawb rau txawv lub hom phiaj.

Natural petroleum jelly yog muab los ntawm roj av residue concentrate xws li alkyl hydrocarbon hnyav roj. Artificial petroleum jelly yog muab los ntawm kev sib xyaw ntawm cov roj ntxhia uas muaj cov roj av ntshiab los yog cov roj paraffin thiab cov roj roj paraffin. Petroleum jelly muaj cov ntxhia roj tsw qab, tsis yog kerosene tsw. Nws tuaj yeem siv los ua cov khoom siv raw rau tshuaj thiab tshuaj pleev ib ce, thiab tuaj yeem siv rau lub tshuab lubrication.

Cov khoom tso saib

Qhov sib xyaw ntawm roj av jelly yog nruab nrab ntawm thiab, ib qho polymer hydrocarbon tau los ntawm cov roj av feem, thiab cov distillation kub siab tshaj 303 ° C. Nws lub ntiajteb txawj nqus yog nyob nruab nrab ntawm 0.820 thiab 0.865, insoluble hauv dej, tab sis soluble hauv roj av thiab ntoo thuv roj.

Petroleum jelly yog cov xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj fluorescent pob tshab oily kua tau los ntawm kev sib sib zog nqus refining ntawm roj av lubricating roj distillate, nrog ib tug nco point ntawm txog 37-54 degrees Celsius. Tsis muaj additives, ya raws thiab mechanical impurities. Soluble nyob rau hauv ether, chloroform, roj av thiab benzene thiab lwm yam organic solvents. Insoluble hauv dej. Zoo tshuaj stability thiab oxidation kuj, nrog zoo antioxidant stability, stability thiab lub teeb stability.

Vaseline tuaj yeem siv rau kev kho mob: Vaseline feem ntau yog cov tshuaj tsis muaj zog hydrocarbon thiab tsis muaj cov kab mob bactericidal; Tab sis nws tsis yog hydrophilic, yuav tsis nqus, smeared ntawm daim tawv nqaij tuaj yeem tsim ib zaj duab xis ntawm nws qhov chaw, yog li dej tsis yooj yim rau evaporate thiab poob, tuaj yeem ua rau daim tawv nqaij noo, thaiv cov kab mob los ntawm huab cua thiab tawv nqaij, yog li. txo qhov muaj peev xwm kis tau.

Ntxiv nrog rau kev siv los ua infiltrating thiab filling capacitors, Vaseline tuaj yeem siv los ua xeb thiab tshuaj tua dej. Thaum ua cov yeeb yaj kiab tsis muaj dej, nws yuav tsim cov yeeb yaj kiab tsis muaj dej tom qab rov qab txheej 2-3 zaug tom qab ziab.

Cov hluav taws xob siv Vaseline ntawm lub cable thiab lub thawv sib txuas kom lubricate nws.

Nws kuj yog siv rau lubrication ntawm lub teeb machinery thiab precision instruments, mechanical lubrication ntawm pleev, zaub mov kev lag luam thiab textile kev lag luam.

Petroleum jelly kuj tseem siv tau rau ntau lub rooj tog zaum, tshuab, thiab lwm yam, los tiv thaiv xeb, lubrication, kho cov kab nrib pleb, thiab lwm yam.

Thov ntawm ob qho tib si ncaj qha frosted glassware los tiv thaiv cov iav los ntawm kev sib tsoo thiab ua rau daig. Feem ntau, cov iav ntsaws rau hauv cov burets yog coated nrog ib txheej nyias ntawm vaseline kom nce ntswj lubrication thiab kaw qhov khoob. Txhawm rau ntxig lub iav raj rau hauv lub qhov ntawm cov roj hmab ntsaws, siv qee cov roj av jelly kom cov roj nplua nyeem ntxiv thiab ua kom lub raj tso tau yooj yim dua.

Ntxiv nrog rau cov saum toj no, thinly thov rau lub koob yees duab lens yuav tsim kom pom tseeb hazy nyhuv.
