Ntsiab ntawm Phenolic Plastics
Phenolic plastics yog thawj cov hluavtaws hluavtaws kub thickosetic thermosetting plastics hauv tib neeg keeb kwm. Lawv cov ntsiab lus tseem ceeb yog phenolic resin, tsim los ntawm kev ua polycondensation ntawm phenol thiab formaldehyde nyob rau hauv acidic lossis alkaline tej yam kev mob. Lub hauv paus chiv keeb ntawm cov khoom no yog txaus ntshai: xyoo 1907, thaum tshawb fawb insulating insulating cov khoom lag luam ntawm phenol thiab formaldehyde tau tawm cov khoom tawv. Qhov no coj mus rau kev tsim muaj ntawm Bakelite, lub ntiaj teb thawj lub tsev muaj roj hmab. Cov khoom siv no tsis tsuas yog hloov cov khoom ntuj (xws li kaus ntxhw thiab ntoo) tab sis kuj tseem yuav tau txais kev lag luam ceev, sai sai ua ib qho tseem ceeb tshaj plaws cov ntaub ntawv ntawm 20 caug xyoo.
Bakelite tsis yog tsuas yog thawj lub hnab yas muaj peev xwm nrog kev kub siab thiab muaj tshuaj lom neeg siv hluav taws xob, kev siv tshuaj lom neeg, thiab lwm yam kev siv. Niaj hnub no, phenolic plastics muaj evolved rau ntau yam hloov kho, xws li cov ntsiab lus roj ntsha- Cov Hluav Taws Xob Cov Hluav Taws Xob xws li Phosphorus thiab Boron txhawm rau txhim kho kev kub nyhuv tiv thaiv hluav taws xob.
Kev txhim kho ntawm cov khoom noj bakelite yog qhov tseem ceeb hauv cov ntaub ntawv txuj ci. Raws li ib qho piv txwv ntawm cov ntaub ntawv phenolic, nws txuas ntxiv mus ua si lub luag haujlwm tseem ceeb hauv kev lag luam. Qhov kev txhais cov yam ntxwv ntawm bakelite yas nyob hauv nws cov thermoset qauv-}} muaj qhov sib txawv ntawm thermoplayics xws li polyethylene.
Cov yam ntxwv ntawm phenolic plastics
Phenolic plastics 'cov txiaj ntsig, suav nrog qhov siab {{0} rwb thaiv tsev, thiab tshuaj lom neeg kuj, ua rau lawv tsis tseem ceeb hauv cov ntawv thov muaj ntau yam. Hauv qab no muab cov ncauj lus kom ntxaws tshuaj xyuas ntawm lawv cov khoom.
High - kub ua hauj thiab thermal ruaj khov
Lub iav hloov qhov kub (TG) ntawm Phexolic Plastics yog siab npaum li 150 {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cia li muaj cov phenolic resins) tuaj yeem tiv taus kub tshaj 350 degree. Cov cuab yeej no ua rau lawv zoo heev nyob rau hauv cov kev kub-ib puag ncig muaj xws li Aerospace lub cav thiab cov pa tso pa hluav taws xob. Piv txwv li, cov ntaub ntawv phenol tseem ruaj khov kho nyob rau hauv 200℃thiab tsis hlawv lossis hloov nws lub npe menyuam yaus "tus huab tais ntawm thermal rwb thaiv tsev cov ntaub ntawv."
Kev Rwb Hluav Taws Xob
Bakelite muaj qhov qis heev dielectric tsis muaj zog thiab tseem nyob ruaj khov dua li cov cua sov thiab av noo, ua rau nws muaj hluav taws xob hluav taws xob zoo tshaj plaws. Nws cov hluav taws xob rwb thaiv tsev cov khoom muaj zog deb tshaj li cov ntawm cov plastics zoo tib yam. Piv txwv li, g -}} 10 qib phenolic laminates tau siv dav hauv cov ntawv luam tawm Circuit Court (PCBs) thiab qib siab hloov. Cov xeeb ceem no ua rau cov khoom phenboum cov ntaub ntawv ib qho kev xaiv saum toj hauv kev lag luam hluav taws xob.
Tshuaj lom neeg kuj thiab tshuab zog
Bakelite yas yog tsis tshua muaj cov acids, alkalis, roj, thiab cov kuab tshuaj yeeb yaj kiab, thiab nws cov tshuaj ruaj khov txawm nce cov hlau. Tsis tas li ntawd, los ntawm kev ntxiv cov iav fiber ntau), nws lub zog tensile tuaj yeem ncav cuag 100 mpa, ua rau lub cev tawv dua li txhuas thaum qhov hnyav tsuas yog ib nrab ntau. Qhov no "lub teeb ci ntsa iab, muaj zog" ua rau nws dav hauv cov tshuab tshuab (xws li cov txiaj ntsig thiab cov kabmob) thiab cov qauv txheej txheem.
Nplaim taws retardant thiab cov pa luam yeeb tsawg
Phenolic Resin yog inherently tus kheej {{0} {{- cov roj ntsha thaum hlawv, sib ntsib thoob ntiaj teb ib puag ncig cov qauv. Piv txwv li, phosphorus - muaj cov khoom siv phenolic tuaj yeem ua tiav cov khoom siv oxygen (LOI)
Kev lag luam thiab txheej txheem
Phenolic cov ntaub ntawv muaj cov nqi phev qis dua li engressing plastics (xws li compression moulding thiab txhaj tshuaj moulding) ua rau lawv haum rau loj- nplai ntau lawm. Los kho cov hom thiab cov zauv sib piv, cov khoom siv tawv, xim, thiab cov khoom sib txawv tuaj yeem hloov kho kom tau sib ntsib ntau yam sib txawv. Bakelite cov khoom, vim lawv tus nqi qis, kuj tau txais lub foothold hauv cov ntawv thov siv, xws li cov xov tooj cua vintage thiab cov tais diav hauv chav ua noj.
Phebolic Yas Ua: Los ntawm Resin Tiav Cov Khoom Tiav
Kev tsim cov phenolic plastics cuam tshuam nrog ntau cov kauj ruam, suav nrog Resin synthesis, filling sib tov, thiab post - ua. Cov hauv qab no yog cov txheej txheem tseem ceeb:
Resin synthesis
Phenol thiab Formaldehyde yauv polycondens nyob rau hauv acidic (xws li aquous ammonia) tej yam los tsim cov khoom siv phev lossis cov khoom siv. Thermoplastic Phenolastic Phenolic Resins yuav tsum tau ntxiv ntawm tus neeg kho tus nqi kho (xws li haxosetting Phenolic Resins tuaj yeem kho ncaj qha los ntawm tshav kub.
Zuj Sib Tw
Nyob ntawm daim ntawv thov cov cai uas yuav tsum tau ua, ntau cov fillers tuaj yeem raug ntxiv rau Resin:
