Cov Roj Dawb 26 CAS NO.8042-47-5
Khoom Description
- Cov roj dawb, feem ntau yog hais txog cov roj ntxhia dawb.Nws yog ib qho tshwj xeeb sib sib zog nqus refined ntxhia roj.Cov roj dawb tsis muaj xim, tsis muaj ntxhiab, tshuaj lom neeg tsis muaj zog, thiab muaj lub teeb pom kev zoo.Lub hauv paus muaj pes tsawg leeg ntawm cov roj dawb yog saturated hydrocarbon qauv.Cov tshuaj tsw qab hydrocarbons, nitrogen, oxygen, sulfur thiab lwm yam tshuaj yog ze rau xoom.Vim qhov no super refining qhov tob, nws yog ib qho nyuaj rau kev siv cov feem ntau hnyav nyob rau hauv cov txheej txheem tsim tiag tiag, yog li qhov hnyav molecular ntawm cov roj dawb feem ntau yog nyob rau hauv thaj tsam ntawm 250-450.Nws muaj qhov zoo oxidation stability, tshuaj stability, lub teeb stability, tsis muaj xim, tsis muaj ntxhiab, thiab tsis corrode fiber ntau textiles.
- Cov roj dawb (cov roj ntxhia) hu ua cov roj ntxhia dawb lossis cov roj dawb hauv qee thaj chaw.Feem ntau siv yog cov roj ua lag luam-qib dawb, cov roj pleev xim-qib dawb, cov roj dawb kho mob, thiab cov roj zaub mov-qib dawb.Ntau hom roj dawb muaj kev siv sib txawv.
- Tshuaj pleev ib ce qib roj dawb yog tau tom qab sib sib zog nqus refining nrog hydrogenated raw cov ntaub ntawv.Nws yog qhov tsim nyog rau kev lag luam tshuaj pleev ib ce thiab tuaj yeem siv los ua cov roj hauv paus ntawm cov tshuaj pleev thiab softeners xws li cov plaub hau cream, plaub hau roj, lipstick, lub ntsej muag roj, roj tu tawv nqaij, tshuaj pleev thaiv hnub roj, roj me nyuam roj, vanishing cream, thiab lwm yam.
- Tshuaj pleev ib ce qib roj dawb tuaj yeem siv los ua tus neeg sawv cev antistatic, emollient, hnyav, hnyav, thiab hydrocarbon, uas tuaj yeem ua rau muaj kev xav ntawm noo noo, tab sis nws tsis tuaj yeem txhim kho cov tawv nqaij qhuav thiab puas.Muaj ntau qhov kev xav txog seb cov roj ntxhia ua rau cov tawv nqaij puas tsuaj, tab sis nws yog ib qho tseeb tias cov roj ntxhia tsis huv tuaj yeem ua rau muaj kev tsis haum thiab pob txuv ua rau cov khoom, thiab cov neeg uas twb raug kev puas tsuaj los yog cov tawv nqaij rhiab yuav tsum tsis txhob siv nws.Vim nws cov xim thiab cov yam ntxwv, nws feem ntau yog siv rau hauv cov tshuaj pleev xim dawb lossis cov khoom siv tawv nqaij.
Khoom Feature
Cov roj dawb yog cov xim tsis muaj xim uas tsis muaj xim tsis muaj xim uas tsis muaj lossis yuav luag tsis muaj fluorescence.Nws tsis muaj ntxhiab tsw thiab tsw qab thaum txias.Nws muaj me ntsis roj av tsw thaum rhuab.Nws yog insoluble nyob rau hauv dej thiab ethanol, soluble nyob rau hauv volatile roj, thiab miscible nyob rau hauv feem ntau tsis-volatile roj.Lub teeb, cua sov, kua qaub, thiab lwm yam yog ruaj khov, tab sis lub sij hawm ntev raug rau lub teeb thiab kub yuav maj mam oxidize.
Cov feem me me, muaj zog yaj lub zog thiab zoo volatility;
- Cov ntsiab lus saturated hydrocarbon yog ntau dua 99%, thiab cov khoom muaj kev ruaj ntseg zoo
- Tsawg sulfur, tsis tshua muaj ntxhiab, tsis muaj tshuaj lom, saj tsis qab
- Nws yog xim tsis muaj xim, tsis qab, tsis muaj tshuaj lom, tsis muaj nplaim taws, tsis tawg, muaj kev ruaj ntseg zoo heev, lub teeb tsis kam, tshuaj lom neeg ruaj khov, tsis corrode fiber ntau textiles, tsis muaj khaus rau ntawm daim tawv nqaij, thiab muaj kev sib raug zoo.
