Cov tshuaj ntsuam ntim feem ntau yog hais txog cov ntaub ntawv uas sau rau lwm yam khoom kom txog rau qhov theem twg. Hauv tshuaj engineering, nws hais txog qhov khoom siv lub teeb meem hauv lub pej thuam. Hauv kev lag luam polymer tshuaj lom neeg, cov tub lim yog qhov tsim nyog muaj kev hloov kho ntxiv. Yuav luag txhua tus plastics (suav nrog cov thermoplastics thiab cov thermosets), cov roj hmab ntuj thiab cov tshuaj pleev xim siv cov ntim puv ntau.
Cov hlau mesh muab tub lim yog tsuas yog ua los ntawm nws cov hlau tsis xeb hauv txoj kev tsim khoom. Lub siab ntawm corrugated xaim mesh packing yog txo thiab qhov sib cais efficiency yog siab. Txhawm rau qee qhov, cov hlau ntxaij muab tub lim yog feem ntau ua los ntawm nyias cov txheej txheem phab ntsa, voids loj loj, flux loj loj, tsis kam tiv taus kub, tsis kam tiv tshav kub, ua hauj corrosion, thiab cov sib cais zoo.
Cov ntxaij ntim khoom yog qhov tsim nyog rau nws cov khoom distillation thiab nqus cov khoom siv lub tshuab nqus tsev. Rau qee qhov, nws muab tau txoj hauv kev zoo rau kev tsim kho kom rov ua kom zoo dua thiab cov cua sov. Txawm hais tias tus nqi ntawm cov vijtsam ntim tau siab, nws tseem siv dav vim nws qhov kev ua haujlwm zoo. Cov vijtsam ntim muaj cov yam ntxwv ntawm cov qauv kev ua haujlwm me me, tsis kam tiv thaiv qis, siab hloov mus rau qhov chaw ua haujlwm, kev ua haujlwm loj, thiab qhov chaw tshwj xeeb loj (125, 150, 250, 350, 500, 700, thiab lwm yam).
Cov yam ntxwv ntsuam xyuas packing:
1. Muaj ntau lub theoretical paib, cov dej ntws loj thiab tsis tshua muaj siab.
2. Muaj kev kawm zoo nyob rau hauv qis ntsaws. Tus naj npawb ntawm qhov theoretical nce raws li cov roj load txo, thiab yuav luag tsis muaj qhov qis thauj khoom.
3. Ua haujlwm yooj yim.
4. kev ua kom nrov dua tsis pom tseeb.
5. Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov cuab yeej nqus, loj thiab siab siab lub tshuab nqus tsev. Cov khoom siv: stainless hlau, tooj dag, phosphor bronze, qis carbon hlau, thiab lwm yam.
Lub npo packing phaj tuaj yeem qhib qhov muaj qhov me me thiab muaj lub zog ntau ntawm kev ua haujlwm. Rau qee qhov, tsis tshua muaj siab poob qis thiab siab tshwj xeeb thaj tsam hauv cheeb tsam tuaj yeem nce ntau lawm, txo kev siv zog thiab txhim kho kev ua haujlwm zoo thaum ua haujlwm. Cov. Nyob rau tib lub sijhawm, vim muaj cov txheej txheem ntawm kev ntim khoom, cov khoom sib txawv hauv cov khoom tuaj yeem tawm los ntawm lub qhov dej hauv qab ntawm qhov kev ntim, yog li cov kev tiv thaiv kev tiv thaiv kev ua tau zoo heev thiab kev ua haujlwm yooj yim dua li ntawm cov yees zoo tib yam Cov. Hloov rau kev ntim ntauwd ntau lawm, qhov peev xwm ntau lawm tuaj yeem nce 5% thiab cov peev txheej ntau lawm tuaj yeem siab ntxiv 50%.
Cov ntawv ntim tau muaj cov yam ntxwv ntawm lub teeb hnyav thiab cov nqi qis. Nws yog qhov tsim nyog rau cov chaw muaj peev xwm loj heev thaum siv. Txhawm rau qee yam, cov khoom lag luam yog cov polypropylene ua tau zoo thiab tuaj yeem tiv thaiv qhov kub ntawm 100 ° C. Qhov kub ntawm cov iav fiber ntau siv tam polypropylene yas cob pob yog tsawg dua los yog sib npaug li 120 ° C. Cov khoom ntawm ob qho tib si muaj cov tshuaj tiv thaiv ua kom muaj zog. , Qhov zoo ntawm sodium hypochlorite oxide tsawg lub ntiaj teb. Muaj zog tiv thaiv corrosion, tiv thaiv corrosion ntawm acid thiab alkali daws. Cov khoom lag luam tuaj yeem ua haujlwm hauv qab tsis zoo thiab siab. Nws yog dav siv nyob rau hauv kev ua haujlwm ntawm ntau yam nqus thiab desorption li xws li hydrochloric acid, sulfuric acid, natural gas, ib puag ncig tus phooj ywg pov tseg cov roj purification kho thiab desorption thiab degassing li.
