Meltblown nonwoven npuag khoom siv
Meltblown nonwoven fabric machinery yog cov khoom siv high-tech uas ncaj qha tig high-melt-index polypropylene chips rau hauv ntaub. Cov txheej txheem ntau lawm suav nrog melting polypropylene chips siv cov ntsia hlau extruder, uas yog ces ejected los ntawm spinneret qhov los tsim fibers. Cov fibers no muaj zog stretching nyob rau hauv high-speed (1300m / min) cua kub ntws, tsim tsis tshua muaj zoo luv fibers. Cov fibers no ces adsorbed mus rau hauv txoj kab hlau rhuav, qhov uas lawv ua rau ib leeg vim qhov kub thiab txias, tsim cov ntaub ntawv meltblown nonwoven, uas yog dov thiab ntim.
Cov cuab yeej tseem ceeb thiab kev ua haujlwm ntawm meltblown nonwoven npuag ntau lawm kab yog raws li nram no:
Ntsia Hlau Extruder:Cov ntsia hlau txoj kab uas hla feem ntau yog 100-120 hli nrog qhov ntev / qhov sib piv ntawm 30, tsom rau melting chips.
Metering twj tso kua mis:Nws lub luag haujlwm yog kev ntsuas qhov tseeb los tswj cov zis thiab fiber ntau fineness. Nws yog lub iav twj tso kua mis uas tsis tu ncua xa cov yaj mus rau spinneret.
Melt lim:Nws lim tawm impurities los ntawm yaj los tiv thaiv clogging ntawm spinneret qhov.
Conveying net kab hlau rhuav:Nws sib npaug tau txais thiab kis cov fibers meltblown mus rau hauv lub vas, xa mus rau pem hauv ntej, nrog lub tshuab nqus tsev hauv qab kom tso cua kub.
Spinning lub thawv:Ib qho khoom siv tseem ceeb hauv cov txheej txheem meltblown, nws muaj ib lub phaj ntev spinneret uas muaj cov kab ntev ntawm qhov spinneret, feem ntau txog 1500 qhov ib 'meter'. Cov cua kub nozzles tau nruab rau ntawm ob sab ntawm lub phaj spinneret, thiab cov cua kub cua nozzles tau nruab rau hauv qab no, tsim lub kaum sab xis 50b nrog lub qhov spinneret. Qhov no tam sim ntawd ncab cov fibers nrog high-ceev cua kub khiav, rhuav lawv mus rau hauv ultrafine fibers.
Feeding system:Muaj 3 metering hoppers rau ntsuas dawb chips, masterbatch, thiab additives, feem. Peb cov khoom no nkag mus rau hauv cov khoom sib tov hauv qab no rau kev sib xyaw ua ke ua ntej ntau lawm.
Cua kub blower thiab rhaub:Muab qhov kub thiab siab ntawm cov cua kub uas siv rau spinning airflow stretching, rhuab hluav taws xob nrog lub zog tseem ceeb.
Winder txais yuav:tag nrho tsis siv neeg winding rau yob thiab ntim cov ntaub meltblown.
