Kev lag luam dav dav thiab cov txiaj ntsig siab txhawb nqa kev loj hlob sai ntawm kev lag luam khoom siv hauv tsev me me, cov kab ntau lawm tau nyob thoob plaws hauv lub tshuab ua mov, induction cooker, hluav taws xob frying lauj kaub, tshuab ziab plaub hau thiab hluav taws xob, cov khoom siv hauv tsev me me tau dhau los ua qhov tsim nyog ntawm cov tsev neeg niaj hnub no.Feem ntau ntawm cov khoom siv hauv tsev me yog ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig, txhawm rau tiv thaiv nws cov khoom ua haujlwm ntau yam, cov txheej kuj tau muab tso rau hauv qhov kev ua tau zoo ntawm qhov kub thiab txias thiab hnav tsis kam.Nyob rau tib lub sijhawm zoo zoo nkauj thiab lwm yam kev ua tau zoo tuaj yeem ua tau raws li kev xav tau ntawm kev lag luam.
Ib qho, silicone txheej
Silicone txheej yog ib qho ntawm thawj zaug thiab feem ntau siv cov txheej txheem kub-resistant rau cov khoom siv hauv tsev me hauv Suav teb.Silicone txheej yog tsuas yog tsim los ntawm silicone resin raws li lub ntsiab tivthaiv, silicone resin qhia ib tug complex network staggered qauv, ruaj khov tshuaj, zoo kub kuj.Kev ua haujlwm kub ntawm cov khoom siv hauv tsev me feem ntau yog qis dua 300 ℃, thiab qhov kub siab tshaj plaws ntawm silicone txheej tuaj yeem ncav cuag 300 ℃.Los ntawm qhov kev xav ntawm qhov kub thiab txias ua haujlwm, silicone txheej yog qhov tsim nyog rau cov khoom siv hauv tsev me.
Txhawm rau ua kom tau raws li qhov xav tau ntawm ob peb lub tsev me me ua haujlwm kub tshaj 300 ℃, cov chaw tsim tshuaj pleev xim ntawm cov organic silicon txheej hloov kho, lub hauv paus ntsiab lus ntawm kev hloov kho yog txo qis cov khoom xyaw uas tsis kub kub resistant xws li cov ntsiab lus hydroxyl, nce Si - O - Si cov yawm sij thiab qhov kev faib ua feem ntawm qhov kub thiab txias resistant inorganic Cheebtsam, ua ke nrog cov khoom siv niaj hnub sib xyaw ua ke ua cov thev naus laus zis, Kev kub siab ua haujlwm ntawm silicone txheej yog qhov zoo dua, txawm tias mus txog 600 ℃.
Silicone txheej tsis tsuas yog muaj qhov kub thiab txias, tab sis kuj muaj zog adhesion, siab txheej hardness, txheej txheem yooj yim thiab tus nqi qis.Cov txiaj ntsig zoo no ua rau cov txheej txheem silicone ci hauv cov khoom siv hauv tsev me me thiab nyiam los ntawm cov khoom siv hauv tsev me.Tab sis qhov tsis txaus ntawm silicone txheej kuj pom tseeb, feem ntau hauv cov hauv qab no:
(1) backsticking phenomenon.Cov txheej txheej npaj los ntawm silicone txheej yog siv zog rau hauv molecular thermal txav ntawm qhov kub thiab txias, thiab cov qauv yuav soften.Thaum sib cuag nrog cov khoom ntse, cov txheej txheem silicone txuas rau saum npoo ntawm cov khoom siv hauv tsev me me yog qhov ua rau khawb thiab lwm yam kev puas tsuaj rau txheej txheej tshwm sim.
(2) Cov teeb meem kev nyab xeeb.Muaj qee cov khoom xyaw lom hauv cov txheej silicone, uas yuav maj mam kis los ntawm sab hauv mus rau qhov chaw los ntawm kev nkag mus, tshwj xeeb tshaj yog cov txheej txheem ncaj qha rau hauv kev sib cuag nrog zaub mov, tej zaum yuav muaj kev phom sij rau zaub mov;
(3) Ultra-siab kub kuj.Nrog rau kev txhim kho ntxiv ntawm kev siv kub ntawm qee cov khoom siv hauv tsev, kev ua haujlwm kub ntawm cov khoom siv hauv tsev me me txawm tias mus txog 600 ℃, yuav ua li cas txhawm rau txhim kho kev siv kub ntawm silicone txheej tau dhau los ua qhov teeb meem ceev kom daws tau.Tam sim no, ib tug me me ntawm cov loj silicone txheej manufacturers nrog r & d lub zog yog ua cov kev tshawb fawb muaj feem xyuam thiab tau ua ib co kev vam meej, tab sis tseem muaj ib tug ntev txoj kev mus los ntawm kev siv tswv yim.
Ob, fluorocarbon txheej
Fluorocarbon txheej, raws li cov khoom siv tshiab, tsis tau siv sij hawm ntev hauv tsev thiab txawv teb chaws, tab sis nws qhov kub thiab txias tsis kam, muaj zog corrosion kuj, nws tus kheej tu, muaj zog adhesion thiab super huab cua tiv thaiv tau dav kev txhawj xeeb.Fluorocarbon txheej yog cov khoom tseem ceeb ntawm fluorine resin, nws cov tshuaj muaj zog ruaj khov, zoo heev kub tsis kam.Cov khoom siv hauv tsev me me coated nrog fluorocarbon txheej tuaj yeem siv txuas ntxiv hauv ib puag ncig ntawm 260 ℃ tsis muaj kev hloov pauv, thiab fluorocarbon txheej yog insoluble hauv roj, yuav tsis hnov mob nrog zaub mov, kev nyab xeeb zoo.Qhov zoo ntawm fluorocarbon txheej yog pom tseeb, tab sis qhov tsis zoo kuj tseem ceeb heev.Nws shortcomings yog manifested nyob rau hauv nws tus kheej kub tsis kam, hardness thiab kev tsim kho ntawm peb yam.Lub hardness ntawm fluorocarbon txheej ntawm ib txwm kub tsuas yog 2-3h, uas yog hais tias, fluorocarbon txheej ntawm ib txwm kub tsis xav tau ib tug duav, steel hlau txhuam, los yog tsuas yog nrog rau cov ntiv tes yuav khawb fluorocarbon txheej, xws li fluorocarbon txheej. siv nyob rau hauv hluav taws xob irons ntsib cov nyees khawm thiab lwm yam khoom ntse feem ntau tshwm sim khawb puas txheej tshwm sim.Fluorocarbon txheej tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig ntawm 260 ℃, thiab zoo li yaj thaum qhov kub siab tshaj qhov no.Qhov qis hardness ntawm fluorocarbon txheej txiav txim siab qhov nyuaj ntawm fluorocarbon txheej hauv kev tsim kho thiab kev siv tshuab.Yuav ua li cas kom cov adhesion thiab smoothness ntawm fluorocarbon txheej hauv cov txheej txheem sib txuas yog qhov tseem ceeb tshwj xeeb.Kev txhim kho yav tom ntej ntawm kev ua tau zoo fluorocarbon txheej:
(1) daws qhov tam sim no hnyav-raws li kub tsis kam, hardness thiab hnyav kev tsim kho thiab lwm yam teeb meem;
(2) ntsuab ib puag ncig tiv thaiv dej-raws li fluorocarbon txheej;
(3) Composite ntawm nanomaterials thiab fluorocarbon coatings los txhim kho cov txheej ceev thiab lwm yam khoom siv.
Peb, hmoov txheej
Hmoov txheej tau dav lees paub tias "Efficiency, tob, Ecology thiab Economy" txheej vim lawv qhov zoo ntawm tsis muaj cov organic hnyav, tsis muaj kuab paug, kev siv siab thiab kev siv hluav taws xob tsawg.Cov hmoov txheej tuaj yeem muab faib ua cov hmoov txheej thermoplastic thiab thermosetting hmoov txheej raws li cov yeeb yaj kiab sib txawv.Cov khoom siv me me hauv tsev siv li cas yog cov khoom siv hluav taws xob kub cov qauv hmoov txheej, nws txoj hauv kev yog siv cov resin nrog me me molecular hnyav thiab curing tus neeg saib xyuas los tsim cov kev sib txuas sib txuas los tsim cov txheej txheem macromolecule hauv qhov kub thiab txias.Hauv cov khoom siv hauv tsev me me, polyester hmoov txheej, acrylic hmoov txheej, epoxy hmoov txheej thiab polyurethane hmoov txheej yog siv ntau dua.Hmoov txheej tau tsim sai heev nyob rau hauv xyoo tas los no, nrog ntau thiab ntau hom thiab kev ua tau zoo dua.Kev siv cov hmoov txheej hmoov tseem yog siab heev rau cov khoom siv hauv tsev me me nrog tus nqi qis.Nws cia siab tias cov tuam txhab txheej txheej tuaj yeem tsim cov nqi qis thiab kev ua haujlwm siab hmoov txheej tsim nyog rau cov khoom siv hauv tsev me.
Ultraviolet lub teeb (UV) curing txheej kuj tshwm sim nyob rau hauv kev ua lag luam tam sim no, nws txoj cai yog siv ultraviolet lub teeb los induce photoinitiator los ua photosensitive resin unsaturated pawg tseem ceeb cross-linking cov tshuaj tiv thaiv los tsim cov qauv ntawm txheej.Txawm hais tias kev tsim cov txheej txheem ntawm uV-kho tau yooj yim, nws yog kim thiab thermal stability ntawm txheej tsis zoo, yog li nws tsis tuaj yeem siv dav hauv kev tsim cov khoom siv hauv tsev me.
