Yuav tsum muaj kev sib khi zoo ntawm cov pob qij txha thiab flanges hauv cov kav dej kom tsis txhob muaj tshuaj lom. PTFE Filled Graphite Seals tuaj yeem tiv taus qhov hloov pauv huab cua thiab siab thaum tiv thaiv kev tawm tsam los ntawm ntau yam tshuaj.

3. Reactors thiab cia cov hlab ntsha
Cov tshuaj reactors thiab cov hlab ntsha khaws cia feem ntau muaj cov tshuaj corrosive los yog tshuaj lom. Kev siv PTFE Stem Seals ua kom lub ntim ntawm cov ntim no thiab tiv thaiv cov tshuaj los ntawm kev nkag mus rau hauv ib puag ncig.

4. Cov khoom siv distillation thiab sib cais
Hauv cov txheej txheem tshuaj, cov kab distillation thiab lwm yam khoom siv sib cais yuav tsum muaj cov ntsaws ruaj ruaj uas tiv taus qhov kub thiab txias thiab tshuaj corrosion. Graphite Stem Seal muaj peev xwm ua haujlwm tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig ntawm cov cuab yeej no.

5. Thaum tshav kub kub exchanger thiab cua txias system
Thaum tshav kub kub exchangers thiab cua txias tshuab yog dav siv nyob rau hauv kev lag luam tshuaj los tswj qhov kub thiab txias nyob rau hauv cov txheej txheem. PTFE Filled Graphite Seals tuaj yeem tiv taus qhov kub thiab txias thiab tshuaj lom neeg corrosion nyob rau hauv cov tshuab no, kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm lub cev.

6. Agitators thiab rotating khoom
Cov agitators thiab lwm yam khoom siv rotating hauv cov khoom siv tshuaj lom neeg yuav tsum muaj kev sib khi zoo los tiv thaiv cov kua los yog roj. PTFE Filled Graphite Seals muab kev hnav zoo heev thiab nws tus kheej lubricating zog haum rau cov kev cai ntawm cov ntawv thov no.

Kev xaiv thiab tu

Thaum xaiv PTFE Filled Graphite Stem Seals, cov hauv qab no yuav tsum tau txiav txim siab los xyuas kom meej qhov ua tau zoo thiab tsim nyog:

■ Daim Ntawv Thov Ib puag ncig:
Xav txog cov hom thiab cov ntsiab lus ntawm cov tshuaj uas lub foob yuav raug, nrog rau qhov kub thiab txias ntawm qhov chaw ua haujlwm.
PTFE muab tshuaj lom neeg ruaj khov zoo, thaum graphite fillers txhim kho cov khoom hnav tsis kam thiab thermal stability.

■ Kub Resistance:
Cov khoom siv PTFE muaj peev xwm tiv taus kub txog 260 degree (500 degree F), thaum lub graphite muab tub lim muab cov thermal stability ntxiv rau kev siv kub.

■ Mechanical Behavior:
Graphite fillers txhim kho PTFE qhov hnav thiab kev ua haujlwm siab, ua rau nws haum rau cov cheeb tsam nrog kev kub siab thiab thauj khoom.

■ Kev sib txhuam coefficient:
Kev sib xyaw ua ke ntawm PTFE thiab graphite muab cov coefficient qis ntawm kev sib txhuam, pab txo lub zog poob thiab txuas lub neej foob.

■ Nqi-zoo:
Txawm hais tias graphite-filled PTFE cov ntaub ntawv yuav kim dua li PTFE uas tsis tau sau, lawv cov kav ntev thiab kev txhim kho kev ua tau zoo tuaj yeem muab cov txiaj ntsig zoo dua rau lub sijhawm ntev.

Txhawm rau tswj xyuas qhov ua tau zoo ntawm PTFE Filled Graphite Stem Seals, cov lus pom zoo hauv qab no yuav tsum ua raws li:
