Ethylene Vinyl Acetate EVA ua

Ethylene Vinyl Acetate (EVA) Ua - Melt Pressure Transmitter

EVA (ethylene-vinyl acetate copolymer) resin yog siv dav hauv ntau lub lag luam. Nws cov txiaj ntsig tseem ceeb suav nrog kev yoog raws, tsis muaj qhov kub thiab txias, tshuaj tiv thaiv, adhesion, pob tshab, thiab lwm yam. Daim ntawv thov scenarios ntawm EVA nrog cov ntsiab lus VA sib txawv heev (qhov siab dua VA cov ntsiab lus, muaj zog dua qhov yooj thiab adhesion, thiab qis dua hardness thiab crystallinity).

Cov khoom ua npuas ncauj (xws li cov ntaub ntawv khau, cov ntaub ntawv ntim cushioning, cov khoom ua si thiab cov khoom siv ua si, cov ntaub ntawv tsim kho / engineering, thiab lwm yam) yog ib qho ntawm nws cov ntawv thov loj tshaj plaws. Kev ua tau zoo ntawm cov khoom ua npuas ncauj yog ze ze rau lub siab yaj thaum lub sij hawm tsim khoom. Yuav ua li cas kom tswj tau lub siab yaj tau ua tus yuam sij rau kev txhim kho cov khoom sib tw, thiab daim ntawv thov yaj siab transmitters tau maj mam tau txais kev mloog.

Tiv tauj peb

Qhov kev ua tau zoo ntawm EVA nrog cov ntsiab lus VA sib txawv ncaj qha txiav txim siab nws daim ntawv thov kev taw qhia, uas tuaj yeem sau tau yooj yim raws li hauv qab no:

VA cov ntsiab lus ntau yam	Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm	Tej thaj chaw thov
5%~15%	Siab hardness, ze rau PE, yooj yim rau txheej txheem	Zaj duab xis, xaim thiab cable, yeeb nkab
15%~30%	Zoo elasticity thiab zoo heev foaming kev ua tau zoo	Foamed khau ntaub, cushioning ntim, photovoltaic encapsulation films
30%~40%	Muaj zog viscosity thiab siab elasticity	Kub yaj kua nplaum, nplaum, cov khoom ua si, erasers

Ib txwm siv thev naus laus zis & kev ua haujlwm

Txoj kev ntsuas siab

1. Cia siab rau lub tshuab ntsuas siab lossis qhov ntsuas tsis ncaj (xws li cov ntsia hlau torque, lub cav tseem ceeb tam sim no) los kwv yees lub siab yaj.

2. Cov ntaub ntawv txheeb xyuas cov ntaub ntawv tsis tu ncua, cov ntaub ntawv tsis tu ncua thiab ncua sijhawm.

Tswj logic

Manually kho tus ntsia hlau ceev, qhov kub thiab txias los yog pub tus nqi raws li kev paub dhau los muaj cov lus teb qeeb: tsis muaj qhov tiag - lub sij hawm tawm tswv yim kaw - voj tswj, thiab cov txheej txheem loj hloov pauv.

Cov teeb meem tshwm sim nrog cov khoom siv niaj hnub

Kev ntsuas siab tsis raug
Cov ntaub ntawv ncua thiab poob
Kev tswj tsis txaus ntawm kev hloov pauv siab
Khoom siv overload txaus ntshai
Cov txheej txheem cia siab rau kev siv phau ntawv

Mechanical meters yog nquag drift, thiab indirect parameters tsis tuaj yeem cuam tshuam qhov tseeb yaj lub xeev.

Tsis tuaj yeem ntes cov kev hloov pauv sai sai hauv lub sijhawm tiag tiag, ua rau cov khoom lag luam tsis zoo.

Cov qauv ntawm tes tsis sib xws (qhov sib txawv, qhov qis kaw ntawm tes).

Tshaj -siab tuaj yeem ua rau cov lim dej tawg, cov dej xau tuag, thiab txawm tias muaj xwm txheej nyab xeeb.

Cov khoom tsis zoo sib xws thiab kev hloov pauv ntev thiab kev debugging.

Piv txwv li, thaum lub sij hawm foaming txheej txheem ntawm lub Hoobkas khoom khau, tsis pom kev nce siab nyob rau hauv lub melting chamber, uas ua rau tus ntoo khaub lig- txuas tus neeg sawv cev rau decompose ntxov ntxov, ua rau ib feem ntawm lub cev qhuav dej thiab tsis sib xws hardness ntawm cov khoom.

Txheej Txheem Technology daws nrog Melt Pressure Transmitter

Core Instruments

Kub kub yaj siab transmitter

Technical yam ntxwv yuav tsum tau ua

1. Kev kub siab thiab kub siab ua haujlwm: kub tsis kam> 200 degree, siab tsis kam> 50MPa (adaptable rau EVA foaming txheej txheem qhov rais).

2. Kev sib cuag ncaj qha nrog yaj: Cov khoom siv ntsuas qhov kawg yog ua los ntawm cov hlau tsis muaj steel diaphragm (15-5PH), uas yog resistant rau yaj corrosion thiab hnav.

3. Tiag -lub sij hawm cov teeb liab: 4 ~ 20mA lossis digital tsheb npav (xws li CANopen) tso zis, millisecond teb.

4. Integrated installation: Xov los yog flange ntsia nyob rau hauv lub confluence seem ntawm lub extruder, tuag lub taub hau los yog foaming pwm kab noj hniav.
