Multi-batch variable-formula zoo tshuaj reactors, PCB ntub tshuaj ntau lawm rhiav, muaj pes tsawg leeg- tsis ruaj tsis khov muaj khib nyiab kua tso tsheb hlau luam thiab cov organic hnyav rov qab systems nquag ntsib complex composite corrosion superimposed los ntawm acid- puag alternation thiab ntev - lub sij hawm immersion ntawm organic solvents. Nyob rau hauv cov xwm txheej zoo li no, cov txheej txheem cov kua dej tau hloov pauv tsis tu ncua ntawm cov kua qaub, alkali thiab ntau cov kuab tshuaj organic, nrog rau lub sijhawm tu lub tank thiab ua tiav qhov nruab nrab hloov. Cov khoom siv cua sov xws li 316L stainless hlau thiab titanium ntshiab yog nyob ntawm cov yeeb yaj kiab passivation rau kev tiv thaiv. Cov khaubncaws sab nraud povtseg no yooj yim rau kev puas tsuaj nyob rau hauv alternating acid-puag yaig thiab hnyav infiltration o, ua rau pitting perforation, sab hauv tsis kam xaim luv luv Circuit Court thiab tsis xav txog ntau lawm shutdowns. Fused quartz heaters poob kev ua tau zoo sai sai thaum hu rau alkaline kua lossis cov organic sib xyaw. Integrated compression- molded PFA heaters txais ib qho seamless fluoroplastic cladding thev naus laus zis, tso siab rau kev sib cais ntawm lub cev kom cais cov cua sov sab hauv los ntawm cov xov xwm nyuaj sab nraud. Daim ntawv no tham txog nws qhov kev sib cais los tiv thaiv{14}} txoj cai corrosion, ntawm - qhov chaw hloov kho, kev txwv kev ua haujlwm thiab cov qauv kev xaiv engineering, thiab tsim cov kev ntsuas kev ua tau zoo rau plaub hom cua sov sib dhos nyob rau hauv qhov sib txawv ntawm kev ua haujlwm corrosion.
1. Kev rho tawm los tiv thaiv-Txoj cai corrosion thiab cov txiaj ntsig tseem ceeb
Sib txawv los ntawm kev tiv thaiv tsis zoo ntawm cov khoom siv cua sov hlau, kev sib xyaw ua ke- pwm PFA tag nrho qhwv cov cua sov ua tiav tag nrho - qhov chaw tawm dag zog lub cev. Qhov sib xyaw ua ke thermo-compressed txheej sab nrauv tsis muaj qhov sib dhos, vuam seams lossis micro- qhov hws, thaiv cov kab nkag mus rau cov kua qaub ions, alkali ions thiab cov organic hnyav molecules. PFA fluoropolymer boasts zoo heev los tiv thaiv - o muaj peev xwm o thiab ntev - lub sij hawm thermal aging stability. Nws yuav tsis bulge, tev tawm los yog raug kev txom nyem los ntawm polymer saw degradation tom qab ntev -lub sij hawm alternating immersion nyob rau hauv mixed organic thiab inorganic corrosive kua. Nws lub ultra- du nto sab nrauv zoo txo qhov adhesion ntawm colloidal polymers, crystalline ntsev sediments thiab viscous sludge, tuav ruaj khov thaum tshav kub kub pauv efficiency thaum lub sij hawm intermittent batch manufacturing. Lub caij no, lub plhaub PFA insulating tshem tawm cov hluav taws xob tam sim no thiab hluav taws xob hluav taws xob hluav taws xob hluav taws xob hauv cov chaw ua haujlwm tshuaj lom neeg, txhim kho kev nyab xeeb ntawm cov khoom ntub dej - cov txheej txheem ntau lawm.
