Yuav Xaiv Lub Drainpipe li cas

1. Tshawb xyuas qhov tshwm sim
Ua ntej ntawm tag nrho cov, thaum xaiv ib tug drainpipe, nws nyob ntawm qhov tsos. Ib tug zoo drainpipe yog uniform xim, nrog ib tug du sab hauv phab ntsa thiab ci ntsa iab nto. Ntawm qhov tsis sib xws, yog tias cov xim ntawm cov kav dej yog xim dawb lossis daj, nkig thiab tawv, thiab cov phab ntsa sab hauv yog ntxhib, feem ntau yog cov kav dej tsis zoo.
2. Tshawb xyuas qhov toughness
Qhov thib ob, thaum xaiv cov kav dej ntws, nws nyob ntawm nws qhov toughness. Cov kav dej zoo muaj qhov ua haujlwm siab thiab muaj zog toughness. Txawm hais tias nws khiav los ntawm lub tsheb, nws tsuas yog ua tiaj tus thiab yuav tsis tawg. Hloov pauv, yog tias lub raj xa dej tsis yooj yim, feem ntau yog tshwm sim los ntawm cov tub lag luam ntxiv ntau cov calcium hmoov rau cov khoom siv txhawm rau txuag nqi thaum ua haujlwm.
3. Corrosion kuj
Tom qab ntawd, thaum xaiv cov kav dej, nws nyob ntawm nws qhov kev tiv thaiv corrosion. Cov kav dej zoo tsis yog tsuas yog cuam tshuam los ntawm av corrosion, tab sis kuj muaj corrosion kuj zoo rau acids thiab alkalis. Nws kuj tsis tshua muaj kab mob fungi thiab kab mob. Lub neej ib txwm muaj siab li 30-50 xyoo.
4. Extensibility
Thaum kawg, thaum xaiv lub raj xa dej, nws nyob ntawm nws qhov ductility. Cia li sim ua txhaum lub qhov dej. Yog tias nws tsis yooj yim rau khoov, nws txhais tau tias nws tsim nyog. Tsis tas li ntawd, thaum xaiv cov kav dej, xyuam xim rau nws cov yeeb nkab thickness thiab seb nws ua tau raws li lub teb chaws tus qauv.
