Nws feem ntau cuam tshuam rau cov khoom siv. Feem ntau, refineries tsis xav tau cov kua qaub siab, tab sis cov neeg muas zaub uas yuav cov roj refined yuav tsis yuav cov roj uas muaj cov kua qaub siab.
1. Cov kua qaub siab ntawm cov khoom siv roj corrodes lub tsev thiab txo cov kev pab cuam lub neej ntawm cov khoom siv;
2. Thaum cov kua qaub ntawm cov roj transformer nce, cov conductivity ntawm transformer roj yuav zoo dua thiab cov rwb thaiv tsev kev ua tau zoo ntawm cov roj yuav zoo dua. Thaum qhov kev khiav hauj lwm kub siab, cov khoom siv fiber ntau rwb thaiv tsev yuav muaj hnub nyoog, tshwj xeeb tshaj yog cov ntsiab lus molecular acid tsawg yuav nce. Thaum muaj dej hauv cov roj, qhov rwb thaiv tsev ntawm cov khoom siv hluav taws xob yuav poob qis, thiab lub neej ua haujlwm ntawm cov khoom siv yuav luv luv.
3. Qhov nce ntawm cov kua qaub ntawm cov roj cav qhia tias cov roj zoo yog kev laus. Cov naphthenic acid soaps thiab lwm yam khoom tsim nyob rau hauv cov roj tuaj yeem txhawb cov emulsification ntawm cov roj, ua rau lub lubricating kev ua tau zoo ntawm cov roj, ua rau hnav thiab kub ntawm lub tshuab qhov chaw, thiab cuam tshuam rau kev nyab xeeb ntawm cov khoom siv.
4. Kev nce acidity ntawm hluav taws-resistant roj thaum lub sij hawm ua hauj lwm yuav txo lub ntim resistivity ntawm hluav taws-resistant roj, ua rau corrosion ntawm servo valve thiab hem lub lag luam kev nyab xeeb ntawm chav tsev.
