Kev tsim cov txheej txheem ntawm PP meltblown lim cartridges yog txheej txheem uas siv cov khoom noj- qib polypropylene (PP) ua raw khoom, thiab los ntawm cov kauj ruam xws li siab - kub melting, siab - ceev spinning, fiber ntau web tsim, thiab kub- melt shaping, los tsim ib tug sib sib zog nqus pom cov khoom nrog lub "sab nraum gradient pore".
Core Manufacturing Process: Plaub kauj ruam tseem ceeb
Kev tsim cov PP meltblown lim cartridges yog ib qho kev ua haujlwm zoo tshaj plaws hauv kev tsim khoom, feem ntau muab faib ua plaub theem hauv qab no:
1. Raw Khoom Npaj thiab ziab
* High-cov zaub mov ntshiab- qib polypropylene granules yog siv los ua raw khoom kom ntseeg tau tias lawv tsis yog- tshuaj lom, tsis muaj ntxhiab, thiab ua tau raws li cov qauv kev nyab xeeb ntawm cov dej haus.
* Cov khoom siv raw yuav tsum tau qhuav ua ntej tso tawm kom tshem tawm cov dej noo thiab tiv thaiv kev tsim cov npuas lossis cuam tshuam rau fiber ntau sib xws thaum lub sij hawm siab - kub melting.
2. Melt Spinning: Siab-Tsub Melting + Siab-Speed Hub Airflow Stretching
* Polypropylene granules nkag mus rau hauv cov ntsia hlau extruder thiab yaj mus rau hauv lub viscous flow xeev ntawm qhov kub ntawm 230-260 degree.
* Cov yaj yog extruded los ntawm spinneret orifice thiab ib txhij mus rau siab - cua kub ceev ntawm 340-370℃los ntawm ob sab, ua rau cov yaj mus rau heev stretched, tsim ultrafine fibers nrog ib txoj kab uas hla ntawm tsuas yog 1-4 micrometers.
* Cov txheej txheem no, hu ua "meltblown," yog qhov tseem ceeb rau kev txiav txim siab fiber ntau fineness thiab pore qauv.
3. Fiber Web Tsim thiab txais kev tsim
* Cov tawg ultrafine fibers poob random nyob rau hauv lub zog ntawm airflow thiab coalesce ntawm ib tug rotating txais nruas los yog lub web -forming curtain, tsim ib tug peb - qhov ntev porous fiber web.
* Qhov tau txais kev ncua deb (qhov deb ntawm lub nozzle mus rau lub nruas nto) yog adjustable, siv los tswj fiber ntau ntom thiab lim thickness.
* Cov fibers yog thermally bonded siv lawv tus kheej residual tshav kub thiab cua kub, tshem tawm qhov xav tau rau cov tshuaj adhesives thiab xyuas kom meej cov khoom purity.
4. Curing, Shaping, thiab Post-processing
* Tom qab txias thiab kho, lub vev xaib fiber ntau raug mob rau hauv cov qauv tubular thiab tom qab ntawd txiav, kos, thiab ntim raws li xav tau.
* Kev xaiv ua tiav suav nrog:
Grooving / Embossing: Ua kom thaj chaw saum npoo thiab txhim kho av- tuav lub peev xwm.
Skeleton Reinforcement: Ib txheej sab hauv PP lossis stainless hlau txhawb nqa lub zog compressive, haum rau siab -siab tshuab.
Kev hloov kho hydrophilic: Txhim kho qhov kev sib cais ntawm cov roj- cov dej sib tov, nthuav nws daim ntawv thov rau kev lag luam oily wastewater kho scenarios.
Cov yam ntxwv tseem ceeb: Vim li cas nws thiaj ua tau siab - pom kev ua haujlwm zoo?
| Nta | Kev piav qhia |
| Qib Pore Structure | Loose txheej fibers cuam tshuam cov khoom loj; ntom ntom fibers ntes me me impurities, ua tiav "qib pom" |
| Peb -Dimensional Microporous Network | Randomly interwoven fibers form numerous tortuous channels, possessing high porosity (>75%) thiab av loj- tuav lub peev xwm |
| Lub cev sib sib zog nqus lim | Kev cia siab rau kev cuam tshuam kev siv tshuab thiab "bridging phenomenon" ntawm fibers, nws tuaj yeem ntes cov khoom me dua li qhov nominal precision. |
| Ib -Pib Moulding | Seamless tag nrho cov qauv, tsis muaj adhesion, zam kev kis kab mob thib ob, thiab ua tau raws li FDA cov zaub mov - qib yuav tsum tau muaj |
Cov cuab yeej siv thiab tsis zoo (Nqa cov kab ntau lawm ua haujlwm ua piv txwv)
* Lub tshuab fais fab loj: kwv yees li 16-55kW, dual lub ntsiab tshuab teeb tsa ua kom cov zis ntau ntxiv
* Ntau lawm ceev: Mus txog 3800-4000 cartridges / 24 teev, txhawb kev ua haujlwm tas mus li
* Adjustable parameter:
Pom tseeb: 0.5-150μm (feem ntau 1, 5, 10, 20μm)
Ntev: 10 ", 20", 30 ", 40" (kwv yees 25-100cm)
Sab nraud txoj kab uas hla: 60-115mm, Sab hauv txoj kab uas hla: 28-30mm
* Tswj system: PLC tswj tsis siv neeg, ua kom cov txheej txheem ruaj khov thiab cov khoom sib xws
Extended Application Scenarios
PP meltblown lim cartridges, vim lawv cov tshuaj muaj zog ruaj khov (pH 1-13), qhov kub thiab txias tsis kam, thiab tsis muaj cov kua qaub, yog siv dav hauv:
* Cov tshuab lim dej hauv tsev: Raws li thawj -theem ua ntej- lim, tshem tawm cov khib nyiab thiab xeb.
* RO thim rov qab osmosis systems: Ua ntej- lim los tiv thaiv RO daim nyias nyias.
* Kev lag luam kws tshuaj thiab zaub mov: Precision pom ntawm kev txhaj tshuaj, kua qhov ncauj, thiab dej haus.
* Electronic ultrapure dej npaj: Intercepting particulates kom huv si dej siv nyob rau hauv chip manufacturing.
* Muaj kua lim dej: Haum rau cov xov xwm nyuaj xws li cov kua qaub thiab alkali, cov tshuaj electroplating, thiab cov kuab tshuaj organic.
