Kev xaiv cov txheej txheem ntawm Thermocouple Extension Wire Outer Insulation Materials

Cov txheej txheej rwb thaiv tsev ntawm cov thermocouple extension xov hlau yog nyob rau ntev - lub sij hawm kub kub hluav taws xob, tshuaj corrosion, bending kev sib txhuam nyob ze ntawm kub khiav pwm, thiab lwm yam., lub neej kev pab cuam ntawm cov hlau thiab stability ntawm lub teeb liab nyob ntawm seb cov ntaub ntawv rwb thaiv tsev sib txawv. Kev xaiv ntawm cov khoom siv rwb thaiv tsev tsis zoo yuav ua rau lub tes tsho embrittlement, melting, volatile nag lossis daus tsis ua hauj lwm. Txoj kev tshawb no soj ntsuam plaub cov ntaub ntawv rwb thaiv tsev tseem ceeb thiab tsim nyog kub khiav kub thiab ib puag ncig tej yam kev mob los muab cov txheej txheem xaiv tsis meej rau kev yuav khoom thiab tsim cov hlau.

1. Teflon PTFE insulated

Kev ntsuas kub ua haujlwm: Kev ua haujlwm tsis tu ncua -200℃-260 degree; Instantaneous ncov kub 300 degree.

Qhov zoo: Ultra tsis tshua muaj kev sib txhuam coefficient, tiv thaiv roj, tiv thaiv cov kua qaub thiab alkali corrosion, tsis absorbent, siab insulating kev ua tau zoo, saj zawg zog thiab yooj yim rau khoov, tsis muaj volatile organic teeb meem nag lossis daus.

Disadvantages: kim, hardens ho nyob rau ntev -lub sij hawm tsis kub, yooj yim khawb los ntawm ntse hlau npoo.

Haum rau: General nruab nrab kub kub khiav thaiv nyob rau hauv 260 degree, hluav taws xob huv chav pwm, ntub dej ntug dej hiav txwv rhiav, pwm nrog nquag hlau dabtsi yog khoov layout. Tsis haum rau cov kab hluav taws xob ncaj qha txuas nrog kub khiav manifold tshaj 280 degree.

2. High Temperature Silicone Fiberglass Composite Rwb thaiv tsev

Kub tiv thaiv ntau yam: Nruam 350 degree, tam sim ntawd 400 degree.

Qhov zoo: Ultra kub ua hauj, tsis tshua muaj nqi, zoo saj zawg zog, zoo hnav tsis kam tom qab braided reinforcement, tsis kam mus rau lub sij hawm luv luv kub hluav taws xob nyob ze ntawm nozzles.

Qhov tsis zoo: yooj yim nqus dej noo, siv sijhawm ntev - nyob rau hauv cov av noo ib puag ncig yuav txo cov insulating zoo; Silicone puag roj yuav volatilize thiab carbonize tshaj 360℃los tsim cov residues.

Daim ntawv thov scenario: Extension xov hlau nyob rau hauv kub khiav nozzle, manifold daim hlau nyob rau hauv 10cm, siab -kub LCP/PPS kub khiav pwm, kev lag luam molding rhiav nrog tsawg huv chav yuav tsum. Tsis txhob siv nyob rau hauv kev kho mob ntshiab khoom cleanroom pwm, kom tsis txhob muaj roj vapor paug.

3. Polyimide (PI) rwb thaiv tsev nrog kev ua haujlwm zoo

Kub ua haujlwm ntau yam: Nruam -200℃~ 380 degree, ruaj khov mus ntev kub yam tsis muaj volatilization.

Qhov zoo: Tsawg outgassing, tsis tshua muaj halogen, du nto tsis yooj yim rau khaws cov pa roj carbon plua plav, ultra- ruaj khov insulating kev ua tau zoo nyob rau hauv qhov kub thiab av noo, tsis muaj cov roj organic nag lossis daus, ua raws li cov cai hauv chav kho mob.

Cons: Cov khoom siv siab tshaj plaws, tsis yooj yim dua li PTFE, nws tuaj yeem tawg nyob rau hauv hnyav dua bending.

Haum rau: kub khiav extension xov hlau ntawm kev kho mob implants & pob tshab khoom, precision pwm ntawm high kub engineering yas nrog nruj VOC tswj, siab -kawg automotive tshiab zog manufacturing kab.

4. PVC hom yas rwb thaiv tsev

Kub resistant ntau yam:<100℃only continuous, >120℃softening deformation.

Qhov zoo: Tus nqi qis heev, silky xav.

Disadvantages: Kub kub volatile nag lossis daus, cov roj tsis zoo thiab corrosion kuj, embrittlement tom qab luv luv - lub sij hawm tshav kub kub, rwb thaiv tsev kuj poob qis heev tom qab absorbing noo noo.

Daim ntawv thov scenario: Tsuas yog rau kev sib txuas ntawm qhov deb ntawm cov pwm (ntau tshaj 3 meters deb ntawm qhov kub khiav qhov kub siab). nruj nreem txwv rau ze -kawg xov hlau hlua ntawm cov pwm.

Ua kom tiav cov cai xaiv kev sib tw.
• Nyob ze pwm thaiv (nyob rau hauv 1m ntawm kub khiav manifold / nozzle) Kub qis dua 260℃xaiv PTFE; 260-350℃xaiv silicone fiberglass; chav kho mob huv txhua qhov kub thiab txias xaiv polyimide PI.
• Far-Txoj kab txuas txuas txuas (ntau dua 3m los ntawm pwm) Cov nqi qis PVC tuaj yeem siv rau cov khoom tsis yog-cov pwm pwm; high precision pwm universally siv PTFE kom tshem tawm cov teeb liab cuam tshuam los ntawm PVC laus.
• Cov kab ntau lawm rau corrosive PVC thiab nplaim hluav taws kub retardant yas: Siv PTFE los yog PI insulated cables uas muaj cov tshuaj tiv thaiv zoo, thiab tsis txhob siv silicone fiberglass cables uas yooj yim cuam tshuam los ntawm corrosive vapor.
• Ntau-kab kab noj hniav pwm thaiv nrog nquag khoov: Siv PTFE hloov tau yooj yim rwb thaiv tsev kom tsis txhob rwb thaiv tsev tawg tom qab ntau lub voj voog khoov.

Rwb thaiv tsev cov ntaub ntawv qib yuav tsum tau hais meej meej nyob rau hauv daim duab thaum lub sij hawm txuas ntxiv xaim xaim, yog li cov neeg muag khoom tsis hloov nrog qis- nqi qis- kub PVC thiab cov khoom siv silicone zoo tib yam, uas yuav ua rau cov xaim hluav taws xob thaum ntxov thiab thermocouple teeb liab teeb meem hauv kev tsim khoom.
