Khoom nta thiab kev siv

PF yog qhov ntxov tshaj plaws industrialized yas ntau yam, uas yog thawj industrialized nyob rau hauv lub tebchaws United States nyob rau hauv 1910. Cov ntaub ntawv raw rau zus tau tej cov PF feem ntau yog phenols thiab aldehydes, feem ntau siv yog phenol thiab formaldehyde, uas yog catalyzed los ntawm catalysts xws li acids. thiab cov hauv paus kom tau txais PF los ntawm polycondensation. Muaj ob hom kev lag luam tseem ceeb: txoj kev qhuav thiab txoj kev ntub dej. Raws li kev ua ntawm cov catalysts sib txawv, phenol thiab aldehyde tuaj yeem tsim tau ob hom PF: ib qho yog thermoplastic PF, thiab lwm yam yog thermosetting PF. Cov yav tas yuav tsum tau ntxiv ib tug curing tus neeg sawv cev thiab yuav kho tau nyob rau hauv lub cev-zoo li tus qauv nyob rau hauv lub cua sov, thaum tom kawg tsis xav tau ib tug curing tus neeg sawv cev thiab yuav ua tau ib tug zoo li lub cev raws li ntev raws li nws yog rhuab.

Txawm hais tias nws yog thermoplastic PF lossis thermosetting PF, tsuas yog kev sib pauv network tsim los ntawm kev kho tuaj yeem siv tau. Cov txheej txheem kho yog qhov txuas ntxiv ntawm cov tshuaj tiv thaiv polycondensation ntawm lub cev thiab tsim cov khoom siv lub cev kawg. Cov txheej txheem no txawv ntawm melting thiab solidification ntawm cov thermoplastics. Nws yog irreversible, ob lub cev thiab tshuaj txheej txheem.

(1) Cov yam ntxwv ntawm PF

PF Vim yog cov khoom sib txawv, cov txheej txheem, thiab lwm yam, ntau hom PF tuaj yeem tau txais, thiab lawv cov khoom kuj yuav txawv. Cov hauv qab no yuav tham txog lawv qhov sib xws. PF yog ib qho amorphous uas tsis muaj molecular hnyav polymer uas tsis muaj cov ntsiab lus meej melting. Cov khoom resin tuaj yeem softened los yog melted nyob rau hauv ib tug tej yam kub thiab txias. Nws yog soluble hauv cawv, benzene, acetone, toluene thiab lwm yam kuab tshuaj, tab sis insoluble nyob rau hauv ntxhia roj thiab zaub roj. PF yog polar polymer. Vim muaj cov phenolic hydroxyl pawg, nws tiv taus acid tab sis tsis alkali. Thaum cov degree ntawm crosslinking tsis siab, alkali tuaj yeem depolymerize.

PF yog ib tug polar polymer, yog li nws muaj ib tug loj dielectric tas li thiab ib tug siab dielectric poob tangent tom qab kho, tab sis nws muaj siab rwb thaiv tsev tsis kam thiab dielectric zog, thiab yog ib tug zoo heev zog zaus insulating khoom. PF tsis muaj additives yog nkig tom qab kho thiab muaj qhov nruab nrab txhua yam khoom. Cov khoom siv kho tshuab ntawm PF nrog cov khoom siv ntxiv yog cuam tshuam los ntawm ntau yam, thiab nws cov khoom tsis zoo ib yam.

PF yam tsis muaj cov fillers tsis yog eroded los ntawm cov inorganic acids, insoluble nyob rau hauv feem ntau hydrocarbons thiab chlorides, insoluble nyob rau hauv ketones thiab cawv, tab sis tsis resistant rau corrosion los ntawm concentrated sulfuric acid, concentrated nitric acid, thiab high-kub chromic acid. PF muaj cov cua kub ua haujlwm siab, thiab cov cua sov ua haujlwm tau zoo dua tom qab ntxiv cov fillers, thiab cov khoom siv tshuab kuj hloov nrog cov khoom sib txawv.

PF tuaj yeem txhaj tshuaj molded los ntawm txoj kev zoo ib yam li cov thermoplastics. PF siv rau kev txhaj tshuaj molding yuav tsum tau zoo fluidity, tuaj yeem molded nyob rau hauv qis txhaj tshuaj, thiab muaj thermal rigidity ntau dua thiab hardening ceev. Qhov saum npoo ntawm cov khoom yas muaj gloss zoo, yooj yim demoulding, thiab tsis ua paug pwm. Txawm li cas los xij, kev txhaj tshuaj molding kuj muaj nws qhov tsis zoo. Piv txwv li, lub yaj yog txwv los ntawm hom muab tub lim, thiab nws tsis haum rau molding yas qhov chaw uas muaj ntau yam inserts. Tom qab kho, ntau lub rooj vag thiab cov neeg khiav dej num tsis tuaj yeem rov ua dua thiab tsuas yog muab pov tseg.

(2) Lub hom phiaj tseem ceeb ntawm PF

PF muaj ntau yam kev siv, thiab nws yog thawj qhov chaw hauv thermosetting plastics hauv peb lub tebchaws. Feem ntau ntawm nws cov PF txhaj tshuaj yog siv los tsim hluav taws xob insulating qhov chaw, xws li lub kaus mom, lub qhov (socket), keyboards; automotive cov khoom siv hluav taws xob, ntsuas qhov chaw, cov khoom siv textile, xov tooj casings thiab cov khoom siv txhua hnub. Nyob rau hauv xyoo tas los no, nrog rau txoj kev loj hlob ntawm runnerless molding thiab yas electroplating tshuab, PF tau dav siv nyob rau hauv tsheb tsim thiab hluav taws xob kev lag luam sectors. Nws tuaj yeem hloov cov ntaub ntawv hlau los ua ntau yam khoom siv, thiab tuaj yeem txo qhov hnyav ntawm cov khoom siv thiab txo nqi.
