Cov koob txia lim limyog cov cuab yeej tseem ceeb hauv chaw soj ntsuam thiab chaw kho mob, feem ntau siv rau kev ua kom pom cov kua. Lawv yog cov khoom siv me me, ib leeg siv uas txuas rau thaum kawg ntawm lub koob txhaj tshuaj kom tshem tawm cov khoom, thiab lwm yam paug ntawm cov dej ua ntej kev tshawb xyuas lossis kev txhaj tshuaj. Kab lus no yuav tshawb txog cov tshuaj uas lim, lawv cov ntaub ntawv, thiab yuav ua li cas los xaiv lub lim kom haum rau koj cov kev xav tau. Tsis tas li ntawd, peb yuav hais txog Shanghai pab koom ua lag luam, cov chaw tsim khoom thiab cov khoom xa khoom ntawm cov khoom zooCov Khoom Kho Mob, Nrog rau cov kua txiv ntoo lim dej.
Hom ntawmCov koob txia lim lim
Cov tshuaj pleev cov tawv nqaij lim tuaj ntau hom, txhua tus tsim rau cov ntawv thov tshwj xeeb:
1. Hydrophilic lim dej: cov ntxaij lim dej no tsim los tsim rau cov kev daws teeb meem aqueous. Lawv feem ntau siv nyob rau hauv lub chaw soj ntsuam rau cov qauv npaj, ua kom tiav, thiab kom tsis muaj menyuam. Piv txwv li nylon, polyethersulfone (pes), thiab cellulose acetate lim.
2. Hydrophobic lim dej: cov ntxaij lim dej no siv rau kev lim cov kuab tshuaj organic thiab huab cua lossis roj av. Lawv tsis haum rau cov kev daws teeb meem thaum lawv rov qab dej. Cov ntaub ntawv uas muaj xws li polytetrosrafluoroethylene (PTFE) thiab polypropylene (PP).
3. Sxua Lim: Cov ntxaij lim dej no tau tsim tshwj xeeb rau cov ntawv thov kev daws teeb meem lossis cov kev siv ntawm kev tshaj xov xwm hauv kev coj noj coj ua ntawm tes. Lawv xyuas kom tsis muaj cov kab mob me me tshwm sim thaum lub sijhawm ua haujlwm.
4. Tsis muaj kev lim lim dej tsis huv: siv rau hauv cov ntawv thov uas tsis muaj kev txhawj xeeb tsis yog kev txhawj xeeb, xws li kev tshem tawm dav dav xws li kev npaj khoom siv particle.
Cov ntaub ntawv siv hauv cov kua roj lim
Qhov kev xaiv ntawm cov kuatune lim yog qhov tseem ceeb thaum nws cuam tshuam qhov sib xyaw nrog cov tshuaj uas tau lim:
1. Nylon: paub rau nws cov kev ntsuas hluav taws xob sib xyaw thiab muaj zog. Haum rau kev lim ob qho tib si aqueous thiab organic kuab tshuaj.
2. Polyethersulfone (PES): Muaj cov txiaj ntsig siab thiab cov protein qis dua, ua rau nws zoo tagnrho rau kev siv roj ntsha thiab chaw tshuaj.
3. Cellulose acetate (ca): muaj protein tsawg heev thiab zoo rau cov kev daws teeb meem aqueous, tshwj xeeb hauv kev teeb meem thiab kev kuaj mob.
4. Polytetrafluoroethylene (PTFE): Muaj tshuaj tiv thaiv heev thiab tsim nyog rau kev lim cov kuab tshuaj thiab roj av.
5. Polypropylene (PP): Siv hauv Hydrophobic lim, tiv taus ntau ntau yam tshuaj lom neeg, thiab zoo tagnrho rau huab cua thiab pentration.
Yuav ua li cas xaiv cov koob txhaj tshuaj lim
Kev xaiv cov tshuaj txig tsim nyog muaj ntau yam:
1. Tshuaj sib xyaw ua ke: kom cov lim lim tau sib xws nrog cov kua lossis roj tau lim. Siv cov ntaub ntawv lim lim lim tau tuaj yeem ua rau muaj kev mob siab lossis tsis huv ntawm cov qauv.
2. Pore loj: lub pore loj ntawm lub lim txiav txim siab qhov uas tau muab tshem tawm. Hom Pore ntau qhov ntau thiab tsawg muaj 0.2 μm rau kom tsis muaj menyuam lub hom phiaj thiab 0.45 μm rau kev tshem tawm dav dav.
3. Daim ntawv thov yuav tsum muaj: txiav txim siab tias yuav tsum muaj menyuam kawm ntawv rau koj daim ntawv thov. Siv cov ntxaij lim dej tsis huv rau cov ntawv sau ua piv txwv txog kev coj noj coj ua lossis cov kev daws teeb meem.
4. Ntim kom tau lim: qhov loj me ntawm cov koob txhaj tshuaj lim yuav tsum sib phim qhov ntim ntawm cov kua. Cov ntim loj dua tuaj yeem xav tau cov ntxaij lim dej ntau dua kom ntseeg tau tias muaj kev lim hiam tsis muaj kev sib tsoo.
Shanghai pab pawg tuam txhab ua lag luam: koj tus khub hauv cov khoom kho mob zoo
Shanghai pab pawg lag luam yog ib qho chaw tsim tshuaj paus kev lag luam thiab cov khoom lag luam ntawm cov khoom kho mob zoo, suav nrog ntau yam ntawm cov tshuaj pleev. Nrog rau kev cog lus rau kev ua tau zoo tshaj plaws thiab kev tsim kho tshiab, lawv muab cov khoom lag luam uas tau raws cov qauv zoo tshaj plaws ntawm kev ua tau zoo thiab kev ntseeg tau. Txawm hais tias koj xav tau cov ntxaij lim dej, cov ntawv thov kho mob, lossis kws tshuaj ntsuam,
Hauv kev xaus, nkag siab cov hom, cov ntaub ntawv, thiab cov qauv xaiv ntawm cov kua lim dej yog qhov tseem ceeb rau kev siv ntau yam. Kev sib koom ua ke nrog cov khoom siv txhim khu kev qha zoo li Shanghai pab pawg neeg lag luam uas txhim kho cov khoom lag luam saum toj kawg nkaus uas txhim khu kev ua haujlwm zoo thiab qhov tseeb ntawm koj txoj haujlwm.
