Kev Taw Qhia:
Cov yeeb nkab Polytetrafluoroethylene (PTFE) yog ib yam khoom siv tau ntau yam uas siv tau ntau yam hauv ntau yam lag luam. Nws yog tsim los ntawm kev siv txoj kev extrusion paste. Cov yeeb nkab PTFE uas tsim los ntawm kev extrusion paste yog qhov yooj ywm. Nws tuaj yeem tsim cov yeeb nkab PTFE nrog lub cheeb sab hauv me me li 0.3 hli mus txog 100 hli thiab phab ntsa tuab li 0.1 hli mus txog 2 hli.PTFE hosemuaj kev ruaj khov tshuaj zoo heev, tuaj yeem tiv taus txhua yam kua qaub muaj zog, alkali muaj zog, cov tshuaj oxidants muaj zog, thiab tsis cuam tshuam nrog ntau yam organic solvents. Nws tuaj yeem siv tau ib txwm hauv -60 ℃ ~ + 260 ℃, nrog kev tiv thaiv corrosion txhim khu kev qha thiab zoo heev. Nws tuaj yeem thauj cov roj corrosive muaj zog thiab kua ntawm qhov kub siab. Tsis tas li ntawd, tom qab kho ntawm qhov kub siab 260 ℃ rau 1000 teev, nws cov khoom siv kho tshuab tsis hloov pauv me ntsis. PTFE muaj qhov sib txhuam qis heev, yog cov khoom siv tiv thaiv kev sib txhuam zoo, nws tus kheej lubricating, nws cov coefficient sib txhuam zoo li qub tsawg dua li cov coefficient sib txhuam dynamic, yog li cov kabmob ua los ntawm nws muaj qhov zoo ntawm kev pib tsis kam thiab kev ua haujlwm ruaj khov. Vim tias PTFE tsis yog polar, tiv taus cua sov thiab tsis nqus dej. Nws kuj muaj kev tiv thaiv kev laus zoo heev, tsis nplaum thiab tsis kub hnyiab. Qhov no tsis tuaj yeem hloov los ntawm lwm cov hoses.
Cov lus qhia hauv qab no yog kev siv rau PTFE hose hauv ntau yam lag luam:
1. Kev lag luam tshuaj lom neeg
Vim tias lawv muaj kev tiv taus tshuaj lom neeg siab rau yuav luag txhua yam tshuaj lom neeg,PTFE rajyog ib qho kev xaiv zoo tshaj plaws hauv kev lag luam tshuaj lom neeg. Xws li kev lag luam semiconductor. Cov txheej txheem niaj hnub ntawm kev tsim khoom semiconductor xav tau kev ntsuas thiab kev thauj mus los ntawm cov kua qaub (acids thiab alkalis). Cov no yuav ua rau lub yeeb nkab xa khoom puas tsuaj loj heev hauv lub sijhawm luv luv.
2. Kev lag luam kho mob
Cov khoom tshwj xeeb ntawm PTFE cov kav dej kuj suav nrog cov qauv nto yooj yim los ntxuav. Hauv kaum xyoo dhau los, PTFE cov kav dej tau siv ntau dua hauv cov khoom siv kho mob. Vim yog qhov sib txhuam qis ntawm PTFE lub raj, qhov no txhais tau tias nws qhov chaw du heev thiab yuav tsis npog lossis pab cov kab mob loj hlob. Ntawm lawv, cov hoses siv rau intubation, catheters, pipettes thiab endoscopes. Nws kuj tsim ntau yam twj paj nruag thiab khoom siv, xws li cov kav dej ntws, cov cua tshuab, pob ntseg, kua roj hmab, hnab looj tes thiab lwm yam ntaub so ntswg dag. Tsis tas li ntawd, ntau yam khoom siv ua haujlwm uas cov kws kho mob siv hauv kev tshuaj ntsuam biochemical tib neeg kuj ua los ntawm PTFE cov khoom siv.
3. Kev lag luam dav hlau
PTFE hoses yog cov fluoropolymers uas tsis yooj yim hlawv. Lawv cov coefficient qis ntawm kev sib txhuam tso cai rau lawv ua haujlwm hauv qab qhov kub thiab txias heev. Qhov no yog vim li cas cov raj no siv los ntawm kev lag luam dav hlau los qhwv cov xov hlau thiab cov cables.
4. Kev lag luam tsheb
Hauv cov cav tsheb, cov kav roj zoo ua los ntawm PTFE yog siv rau kev ua kom roj evaporation thiab cov roj rails. Tam sim no, Cov hoses nres hauv khw yog txhua yam hose nres sib dhos nrog cov pob qij txha. Raws li ntau hom nres tsheb, nws muab faib ua hydraulic nres hoses, pneumatic nres hoses thiab vacuum nres hoses. Raws li nws cov khoom siv, nws muab faib ua PTFE nres hose, roj hmab nres hose thiab nylon nres hose. Cov roj hmab nres hose muaj qhov zoo ntawm lub zog tensile muaj zog thiab yooj yim installation, tab sis qhov tsis zoo yog tias qhov chaw yooj yim laus tom qab siv ntev. Yog tias qhov kub qis, lub zog tensile ntawm nylon nres hose tsis muaj zog, yog tias nws raug cuam tshuam los ntawm lub zog sab nraud, nws yooj yim tawg. Txawm li cas los xij,Besteflon lub raj PTFEmuaj cov yam ntxwv ntawm kev kub thiab tsis kub, kev kub siab, kev puas tsuaj, thiab kev tiv thaiv corrosion, uas ua rau nws muaj lub neej ntev thiab tsis tas yuav hloov pauv ntau zaus. Nws tuaj yeem ua rau qhov tsis zoo ntawm ob yam khoom siv
5. Kev lag luam hluav taws xob
PTFE tubing muaj cov yam ntxwv hluav taws xob zoo heev. Lawv muaj cov yam ntxwv dielectric siab thiab cov yam ntxwv poob qis hauv ntau zaus. Yog li ntawd, PTFE kav dej yog siv ua cov khoom siv rwb thaiv tsev zoo, kub siab rau cov xov hlau thiab cov cables, nrog rau cov khoom siv cua sov hluav taws xob thiab cov ntsuas kub. Hauv kev lag luam hluav taws xob, txhawm rau npog cov xov hlau thiab cov cables, cov kav dej PTFE zoo siv, uas tuaj yeem tiv taus qhov kub siab thiab tiv thaiv cov xov hlau los ntawm kev txiav. Tsis tas li ntawd, cov kav dej no muaj ntau yam xim los pab txheeb xyuas cov xov hlau hauv tsev lossis chaw ua haujlwm.
6. Kev lag luam zaub mov
Vim nws yooj yim ntxuav thiab tsis lo, cov kav dej PTFE polytetrafluoroethylene siv tau rau hauv kev lag luam khoom noj. Tshwj xeeb, cov kav dej ua los ntawm PTFE tsis tau ntim yog qhov tsim nyog vim lawv qhov kev tsis sib haum xeeb ntawm lub cev thiab ua raws li cov lus qhia ntawm US Food and Drug Administration. Yog li ntawd, nws tau ua pov thawj tias nws tsis muaj teeb meem thaum kov cov yas thiab txhua yam khoom noj. Yog li ntawd, cov kav dej PTFE feem ntau siv rau hauv cov tshuab kas fes ib txwm muaj. Tsis tas li ntawd, cov kav dej spaghetti ib chav lossis ntau chav thiab cov kav dej kub-shrinkable siv. Cov khoom PTFE tuaj yeem raug sterilized siv txhua txoj kev ib txwm muaj.
7. Kev lag luam ntaub
Kev hloov cov tshuaj hauv cov kav dej siv hauv kev lag luam textile tuaj yeem ua rau xeb. Yog li ntawd, txhawm rau kom tsis txhob muaj teeb meem no, lub raj TPFE siv, thiab lub txheej PTFE raug nqa tawm ntawm cov yob textile
8.3D Kev Lag Luam Luam Ntawv
Hauv kev luam ntawv 3D, cov filament yuav tsum tau hloov mus rau lub nozzle luam ntawv uas yuav tsum tau ua nyob rau hauv qhov kub siab. Vim tias PTFE tubing muaj cov coefficient kub siab thiab cov khoom tsis lo, nws pab kom yooj yim txav cov khoom los ntawm lub nozzle, yog li nws yog cov polymer xav tau tshaj plaws hauv kev lag luam luam ntawv 3D.
Qhov xwm txheej tsis yog alkaline ntawm PTFE tso cai rau nws siv rau hauv kev lag luam tshuaj lom neeg, qhov twg kev hloov pauv ntawm cov kua dej rhiab heev yog qhov tshwm sim ntau. Zhongxin Fluorine plastic Industry Co., Ltd. Tshwj xeeb hauv kev tsim cov yeeb nkab PTFE zoo rau 16 xyoo.
