PTFE capillary tubing? Dab tsi yog nws cov kev ua tshwj xeeb thiab kev siv cov xwm txheej?

I. Cov khoom ntawm polytetrosraethylene capillaries

Polytetrafluoroethylene (ptfe) yog microscopic tubing ua feem ntau los ntawm polytetrosraethylene cob. Lawv muaj npe rau lawv cov taub sab hauv, feem ntau tsawg dua 4 hli, thiab lawv cov qauv ua kom zoo nkauj, uas zoo li tib neeg lub capillaries. PTFE, feem ntau hu ua "tus huab tais ntawm plastics," muaj cov khoom hauv qab no:

1. Tshuaj lom neeg ruaj khov: tiv taus rau cov muaj zog acids, hauv paus, thiab cov kuab tshuaj organic, PTFE tsim nyog rau kev siv hauv cov chaw muaj kev sib raug zoo.

2. Dav kub ntau ntau: ntev-}}}} kev ua haujlwm rau 260 degree, nrog kev ua tau ruaj khov txawm nyob rau qhov kub.

3. Kev txhuam cov coefficient: nrog txoj kev sib txhuam du thiab ib qho kev sib txhuam coefficient ntawm tsuas yog 0.04, PTFE Cov Khoom Taw Qhia Zoo heev rau tus kheej {2} Lubricating cov khoom.

4. Hluav taws xob rwb thaiv tsev: nrog lub dielectric tas li qis li 2.0, PTFE tuaj yeem tiv thaiv siab ntev li 1500v thiab tau siv dav hauv hluav taws xob cov ntawv thov hluav taws xob.

Ii. PTFE capillary tubing npaj cov txheej txheem thiab cov qauv yam ntxwv

Kev tsim cov ptfe capillary tubing yuav tsum muaj ntau cov kauj ruam:

1. Cov khoom siv raw sib xyaw: PTFE dispersion betin yog tov nrog me ntsis ntawm organic huab cua (xws li cov kuab tshuaj naphtha) los ua ib qho yas ua tshuaj txhuam.

2. Nias: Ib chav- kub nias txheej txheem lub raj dawb, uas yog ces qhuav kom tshem cov kuab tshuaj.

3. Siab {- kub sintering: Sintering ntawm qhov kub thiab txias saum toj no

Lub tiav capillary tubing compines siab kho txhua yam lub zog nrog me me precision. Qee cov khoom lag luam ua tiav kev tshaj li 90%, yooj yim kev soj ntsuam cov kua.

III. PTFE capillary tubing xim thiab ntau qhov ntau thiab tsawg

Xim: Tus qauv xim yog milky dawb, thiab cov xim tsis zoo xws li liab, daj, xiav, ntsuab, thiab dub muaj.

Qhov ntau thiab tsawg ntawm PTFE capillary tubing (id * om * 1.4, 1 * 1.4, 1, 1.6, 1.6, 1.5 * 3, 1.5 * 2.5, 1.6 * 2, 1.8 * 2.2, 1.8 * 2.4, 2.4, 2.4, 2.5 * 2.5 * Dankai txhawb kev cai rau kev coj ua tshwj xeeb rau lwm cov lus qhia.

IV. Cov tub ntxhais ua haujlwm zoo ntawm polytetrosraethylene capillaries

Piv rau cov yas yas yas, PTFE capillaries muaj cov txiaj ntsig zoo hauv qab no:

1. Anti {{- cov kua nplaum: colloids, muaju, lossis cov khoom seem tsis yooj yim txuas rau phab ntsa sab hauv, ua kom muaj zog ntawm cov kua dej.

2. Kev laus tsis kam: ntev - Term kev ua tau zoo nyob rau hauv ib puag ncig xws li UV thiab ozone, ua rau nws haum rau kev siv sab nraum zoov.

3. BiCompatibility: tsis - kev lom thiab tsw, nws raws li cov qauv kev kho mob thiab khoom noj kev nyab xeeb.

V. Raug cov ntawv thov ntawm PolytetrosraTrafloethylene capillaries

1. Kev Kho Mob

PTFE capillaries ua lub luag haujlwm tseem ceeb hauv cov tshuaj:

Vascular grafts: raws li cov hlab ntshav cuav, lawv ua piv cov kev ua haujlwm ntawm cov hlab ntshav thiab txo qhov kev pheej hmoo ntawm thrombosis.

Kev tsim txom cov txuj ci: siv hauv cov txheej txheem cardiovascular thiab rodicals, lawv txoj kev du pom cov nqaij mos thiab tso cai rau kev ua kom yooj yim kom tsis muaj menyuam.

Sutures: lawv lub zog siab thiab biocompatibility ua rau lawv ib cov khoom zoo tshaj plaws rau kev phais mob siab.

2. Tshuaj lom neeg thiab kev lag luam

Kev tawm xov xwm kev tawm tswv yim: Ua Tshuaj Qhuas Cov Hluav Taws Xob: Ua cov tshuaj nchuav dej, lawv wallet muaj zog acid thiab alkali ib puag ncig.

High - Purity Reuge Reflection: ua kom cov khoom siv reagents yog cov tshuaj kis tau nyob hauv cov semiconductor thiab tshuaj lag luam.

Kev ntsuas kev ntsuas: saum npoo {{{-} Hloov PTFE capillaries tuaj yeem siv rau kab protein ntau ntxiv thiab nrhiav tau, txhim kho cov rhiab heev.

3. Lwm liaj teb

Cov ntawv thov hluav taws xob thiab hluav taws xob: Siv nws cov nyiaj rawv insulation thiab siab {}} kub tsis kam raws li rwb thaiv tsev rau cov xov hlau.

Kev Lag Luam Khoom Noj: Ua tau raws li cov qauv kev nyab xeeb zaub mov thiab siv rau hauv cov khoom siv mis los thiab dej haus ua.
