Lub PVC dej muab cov yeeb nkab yog ua los ntawm cov khoom siv huv polyvinyl chloride resin ua cov khoom siv tseem ceeb, thiab tom qab ntawd ntxiv qee cov nyiaj stabilizers, lubricants, fillers thiab colorants, thiab lwm yam, los ntawm cov yas extruder extrusion molding thiab txhaj tshuaj molding tshuab txhaj tshuaj molding, thiab thaum kawg. los ntawm kev ua kom txias, Cov txheej txheem xws li kho, shaping, tshuaj xyuas thiab ntim khoom yog tsim.
Cov yam ntxwv tseem ceeb ntawm PVC kav dej:
Lub teeb yuag, yooj yim tuav thiab thauj khoom thiab tshem tawm, tsis tshua muaj ntom, yooj yim siv; zoo corrosion kuj, PVC dej mov yeeb nkab muaj zoo heev acid, alkali thiab corrosion kuj, uas yog heev haum rau kev siv tshuaj lom neeg kev lag luam; Cov dej tsis kam yog me me, PVC yeeb nkab Cov phab ntsa sab hauv yog du, nws cov roughness coefficient tsuas yog 0.009, thiab cov dej tsis kam yog me me, uas zoo heev txhim kho cov xwm txheej hydraulic ntawm cov yeeb nkab network thiab txo cov nqi khiav lag luam; Lub zog txhua yam yog qhov loj, thiab cov yeeb nkab PVC muaj qhov ua haujlwm siab zoo, cuam tshuam thiab ua haujlwm. Tensile zog ua haujlwm; yooj yim thiab yooj yim kev tsim kho, ceev thiab yooj yim yeeb nkab kev twb kev txuas kev tsim kho, tsawg tsim engineering nqi; Tus nqi qis, tus nqi qis ntawm PVC cov kav dej, kev thauj mus los yooj yim thiab kev tsim kho, kev pab lub neej ntev, tus nqi qis tag nrho; tsis cuam tshuam rau cov dej zoo, kev ntsuas kev sib cais Nws tau ua pov thawj tias cov kav dej PVC tsis cuam tshuam rau cov dej zoo thiab tsim nyog rau kev txhawb nqa loj thiab kev thov.
Daim ntawv thov ntau yam ntawm PVC kav dej:
Cov kav dej PVC feem ntau yog siv los ua cov dej hauv tsev thiab cov khoom siv dej rov qab rau cov vaj tse thiab kev lag luam; PVC cov kav dej kuj tseem siv tau rau cov khoom siv dej faus hauv cov tsev nyob thiab cov chaw ua haujlwm; PVC cov kav dej kuj tseem siv tau rau cov kav dej hauv nroog; Cov chaw kho dej kuj tseem muaj cov kav dej PVC hauv cov kav dej; PVC kav dej kuj tshwm sim hauv kev lag luam marine aquaculture; PVC cov kav dej kuj tseem siv rau hauv vaj hauv vaj, dej hauv dej thiab lwm cov kav dej; PVC kav dej muaj ntau yam zoo thiab siv tau zoo, tsis yog hauv lub neej txhua hnub Nws ua lub luag haujlwm tseem ceeb hauv lub neej thiab tseem yog ib feem tseem ceeb ntawm kev lag luam.
