Ntim thiab khaws cia
flake / hmoov: 20kg / hnab, 25kg / hnab, Ntim rau hauv hnab woven, los yog nyob rau hauv Kraft daim ntawv hnab nrog yas liner hauv. Resin yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo ventilated nyob deb ntawm tshav kub qhov chaw kom tsis txhob ya raws thiab caking. Nws cov xim yuav tsaus ntuj nrog lub sijhawm khaws cia, uas yuav tsis cuam tshuam rau qib resin.
Bakelite hmoov thiab phenolic resin hmoov sib txawv.
Dab tsi yog qhov txawv ntawm phenolic resin hmoov thiab bakelite hmoov? Bakelite lub npe tshuaj yog phenolic yas, uas yog thawj ntau yam ntawm cov yas yuav tsum tau muab tso rau hauv industrial ntau lawm. Phenolic resin tuaj yeem npaj los ntawm polycondensation ntawm phenols thiab aldehydes nyob rau hauv lub xub ntiag ntawm acidic los yog alkaline catalysts. Bakelite hmoov yog tau los ntawm kev sib xyaw phenolic resin nrog sawn ntoo hmoov, talc hmoov (filler), urotropine (kho tus neeg sawv cev), stearic acid (lubricant), pigment, thiab lwm yam, thiab cua sov thiab sib tov rau hauv ib lub tov khoom. Bakelite hmoov tau rhaub thiab nias rau hauv pwm kom tau txais cov khoom siv yas phenolic thermosetting.
Bakelite muaj lub zog txhua yam, zoo rwb thaiv tsev, kub tsis kam thiab corrosion kuj.yog li ntawd, nws yog feem ntau siv los tsim cov khoom siv hluav taws xob, xws li cov keyboards, lub kaus mom, lub mloog pob ntseg, xov tooj casings, cov cuab yeej casings, thiab lwm yam "Bakelite" muaj npe tom qab nws. .
