Metric PU Tubing

Peb lub tuam txhab tau tsim nyob rau xyoo 2007 thiab tau cog lus rau kev tshawb fawb thiab kev tsim kho, tsim khoom, thiab muag khoom ntawm polyurethane txij thaum pib. Cov khoom tseem ceeb uas tsim yog polyurethane log, polyurethane boards, polyurethane sieves, polyurethane forklift npog thiab lwm yam khoom polyurethane. Xyoo 2017, peb tau qhia txog cov kab ntau lawm rau cov kav dej polyurethane, uas tau tsim los ze li ntawm 10 xyoo. Lub tuam txhab muaj 7 advanced extrusion ntau lawm cov cuab yeej thiab ntau yam khoom siv kuaj. Cov khoom uas tsim los mas siv polyurethane roj kav, PE gas pipes, PA gas pipes thiab lwm yam kav dej. Lub metric PU tubing tsim tau txais kev qhuas los ntawm cov neeg siv khoom rau nws cov khoom zoo thiab tus nqi tsim nyog.

Feem ntau cov teeb meem nrog metric PU tubing thaum siv thiab lawv cov hauv paus ntsiab lus

1. Nto abrasion, khawb, thiab tom qab tawg.

Qhov no feem ntau yog tshwm sim los ntawm cov khoom zoo (xws li, txhuas plua plav, xuab zeb) tam sim no nyob rau hauv qhov chaw ua haujlwm. Thaum lub sij hawm tubing txav mus, cov khoom no ua rau abrasive hnav, tsim kom muaj kev ntxhov siab cov ntsiab lus ntawm qhov chaw uas pib thiab nthuav tawm qaug zog tawg.

2. Kev qaug zog tawg ntawm cov ntsiab lus ntawm rov khoov dua.

Lub raj yog raug rau cyclic kev nyuaj siab nyob rau lub sij hawm ntev, feem ntau los ntawm reciprocating motion los yog vibration ntawm cov khoom. Cov kab nrib pleb tshwm sim los ntawm qhov chaw tsis xws luag lossis kev puas tsuaj thiab maj mam nthuav tawm los ntawm lub raj phab ntsa kom txog thaum ua tiav qhov tawg.

3. softening, deformation, los yog ceev kev laus nyob rau hauv siab - kub.

Kev khiav hauj lwm kub siab tshaj qhov ua haujlwm zoo ntawm cov khoom siv PU (feem ntau -20℃txog 40 degree). Kev kub siab ua kom cov polymer degradation, ua rau cov khoom poob elasticity, ua nkig, thiab raug kev txom nyem los ntawm kev txo cov neeg kho tshuab lub zog.

4. Hardening, embrittlement, thiab susceptibility rau rupture ntawm qis kub.

Txawm hais tias PU tubing muaj qhov ua tau zoo dua qis dua - qhov kub thiab txias ntau dua li lwm cov yas, cov huab cua txias heev txo nws txoj kev yooj yim thiab ua rau nws cov tawv tawv, yog li txo nws txoj kev cuam tshuam thiab ua rau nws yooj yim tawg hauv kev ntxhov siab.

5. Degradation ntawm kev ua tau zoo tshaj qhov ntev cia (kev laus).

Cov khoom siv lub cev thiab tshuaj lom neeg laus dhau sijhawm. Piv txwv li, tom qab ob peb xyoos ntawm kev khaws cia, metric PU tubing tuaj yeem pom qhov txo qis hauv tensile lub zog thiab kev loj hlob ntawm micro- tawg nyob rau hauv lub raj phab ntsa.

6. Yellowing thiab embrittlement nyob rau hauv ultraviolet (UV) raug.

PU cov ntaub ntawv, tshwj xeeb tshaj yog hom polyether, muaj qhov tsis zoo ntawm UV tsis kam. Ntev ntev raug rau lub hnub ci tawg ua rau cov saw hlau polymer, ua rau tsis muaj xim (daj), embrittlement, thiab poob ntawm cov khoom siv kho tshuab tseem ceeb.

7. Tshuaj tua kab mob thiab corrosion.

Kev sib cuag nrog cov roj tsis sib xws, cov kuab tshuaj, lossis lwm yam tshuaj lom neeg ua rau cov khoom siv PU kom o, muag, lossis tsim cov kab nrib pleb, thaum kawg ua rau cov khoom tsis ua haujlwm.
