Cov Khoom Siv Cov Lus Qhia
(1) 1,2-Propanediol yog ib qho tseem ceeb raw khoom rau unsaturated polyester, epoxy resin, polyurethane resin, plasticizer thiab surfactant.Qhov no polyester unsaturated yog dav siv nyob rau hauv nto coatings thiab reinforced yas.
(2) 1,2-Propanediol muaj viscosity zoo thiab hygroscopicity, thiab yog dav siv los ua hygroscopic agent, antifreeze, lubricant thiab hnyav nyob rau hauv cov zaub mov, tshuaj thiab tshuaj pleev ib ce industries.
(3) Hauv kev lag luam khoom noj khoom haus, 1,2-propylene glycol reacts nrog fatty acids los tsim propylene glycol fatty acid esters, uas yog siv los ua zaub mov emulsifiers;1,2-propylene glycol yog cov kuab tshuaj zoo heev rau cov khoom noj thiab cov pigments.Vim nws tsis tshua muaj toxicity, nws yog siv los ua ib qho hnyav rau cov txuj lom thiab zaub mov xim hauv kev lag luam khoom noj.
(4) 1,,2-Propanediol feem ntau yog siv rau hauv kev lag luam kws tshuaj raws li cov kuab tshuaj, softener thiab excipient rau kev tsim khoom ntawm ntau yam tshuaj pleev thiab tshuaj pleev, thiab raws li ib tug blending agent, preservative, tshuaj pleev, vitamin, Solvents xws li penicillin.Vim hais tias propylene glycol muaj kev sib nrig sib solubility nrog ntau yam fragrances, nws kuj yog siv los ua ib qho hnyav thiab softener rau tshuaj pleev ib ce, thiab lwm yam.
(5), 1,2-Propanediol kuj tseem siv los ua luam yeeb moisturizing agent, mildew inhibitor, ib qho hnyav rau cov khoom siv ua zaub mov lubricating roj thiab zaub mov cim.
(6) Cov tshuaj aqueous ntawm 1,2-propanediol yog cov tshuaj tiv thaiv zoo.Kuj tseem siv los ua tus neeg haus luam yeeb wetting, mildew inhibitor, txiv hmab txiv ntoo ripening preservative, antifreeze thiab tshav kub cab kuj, thiab lwm yam.
Cia
Kev ntsuas kev nyab xeeb: Tsis txhob nqus pa lossis tiv tauj nrog cov khoom no.Siv tsuas yog hauv qhov chaw ventilated.Ntxuav kom huv nrog dej tom qab tuav los yog siv.
Tej yam kev mob rau kev ruaj ntseg cia: Txawm hais tias cov khoom no yuav tsis ignite spontaneously, nws yog combustible.Kev cia ntev ntev yuav tsis ua kom tsis zoo, tab sis qhov qhib yuav nqus dej noo.Kev khaws cia thiab kev thauj mus los ntim yuav tsum yog ua los ntawm galvanized hlau nruas, aluminium lossis stainless hlau.Kev khaws cia thiab kev thauj mus los raws li cov kev cai tshuaj lom neeg tsawg.Tsis txhob sib cuag nrog dej thiab qhov chaw ntub dej.Lub tank yuav tsum huv si, qhuav thiab tsis muaj xeb.Nws yuav tsum tau muab cia rau hauv ib qho chaw uas muaj phab ntsa, qhov cua, thiab kev tiv thaiv los ntawm lub hnub, qhib nplaim taws thiab lwm qhov chaw cua sov.Nitrogen sealing yog pom zoo rau cov tso tsheb hlau luam loj (nrog lub peev xwm ntawm 100 m3 lossis ntau dua).Khaws lub thawv kaw kom nruj.Khaws kom qhuav.
Cia kub: mus txog 40 ° C
