Cov tshuaj tsuag lim cov khoom siv fiber ntau sib faib, sib sau ua ke ntawm ntau feeb ntawm lub qhov hws, thiab lub qhov hws tsis sib xws tau faib, qhov kev tiv thaiv tsis sib haum yog qhov me me, thiab kev ua haujlwm ntawm cov lim dej yog qhov siab, uas ua rau lub lim dej ua tau zoo ntawm qhov tsis-woven kev tiv thaiv kev tiv thaiv daim npog. deb deb tshaj rau cov tsoos daim npog ntsej muag.
SMS tsis-siv npuag siv polypropylene PP (nrog ntuj bacteriostatic thiab hydrophobic yam ntxwv) yog cov khoom siv tseem ceeb, thiab cov khoom siv fiber ntau tuaj yeem ncav cuag 0.5-10um. Cov nplua fiber ntau nrog cov cim capillary ua kom cov xov paj ntau ntxiv rau ib cheeb tsam thiab thaj chaw, kom Meltblown daim ntaub muaj cua zoo thiab yog cov ntaub npog ntsej muag zoo. Yog li ntawd, lub laser npav nto yog ntaub tsis-ntaub ua los ntawm S-txheej polypropylene.
Laser npav
Zoo li txhua yam khoom siv kho mob thiab kev noj qab haus huv, cov cim cuav los tiv thaiv yog qhov tseem ceeb ntawm daim npog qhov ncauj.
Niaj hnub no, piv rau tsoos number case tshuab luam ntawv, laser npav muaj cov yam ntxwv ntawm tsis muaj tshuaj lom, tsis muaj kuab paug, ua hauj lwm zoo, siab txhais, siab txhais tau zoo, thiab tawg tsis kam. Nws tau technically daws tau ib qho ntawm cov tsoos luam ntawv yees. Cov lus nug. Nws tuaj yeem hais tau tias laser npav tshuab thev naus laus zis tau txhawb nqa kev lag luam kev kho mob txij thaum nws yug los.
Lub hauv paus ntsiab lus ntawm laser npav thev naus laus zis yog tshwj xeeb rau irradiate saum npoo ntawm cov khoom siv nrog laser nrog lub zog siab, kom cov nplaim ntawm cov khoom yog vaporized rau cov khoom sib sib zog nqus, lossis tshuaj lom neeg cov tshuaj tiv thaiv uas hloov xim ntawm qhov chaw ntawm cov khoom nyob rau hauv cov nyhuv ntawm lub teeb irradiation, Tawm hauv cov cim ruaj khov. Txij li cov laser ua haujlwm tsis yog kev sib cuag, lub cuab yeej tsis ncaj qha ua rau muaj kev sib txhuam nrog cov nplaim ntawm qhov chaw ua haujlwm, yog li lub laser ua kev nrawm yog qhov nrawm heev, thaj tsam cuam tshuam los ntawm tshav kub ntawm kev ua cov khoom me, thiab tsis muaj suab nrov. Txij li thaum lub zog ntawm lub laser nqaj thiab qhov ceev ntawm nqaj tuaj yeem tsim kho, kev lag luam laser tuaj yeem siv rau ntau qib thiab ntau qib.
Tam sim no, muaj ob lub lees paub cov txheej txheem laser ua: laser thermal processing thiab photochemical processing (tseem hu ua txheej txheem txias).
Thaum lub luv-wavelength ultraviolet laser yog thov rau lub polymer, nws ncaj qha tsoo cov tshuaj sib txuas ntawm cov khoom, kom cov khoom tawg yooj yim tawm hauv cov khoom me me lossis kev ua kom zoo, thiaj li ua tiav lub hom phiaj ntawm kev rho tawm thiab tshem tawm cov khoom, yog li ua kom muaj qhov yooj yim, du thiab yooj yim kom paub cov cim hauv cov khoom. Txij li feem ntau ntawm lub zog siv los rhuav tshem cov ntawv cog lus tshuaj, lub zog me me yog hloov mus rau hauv lub zog thermal, uas tuaj yeem tshem tawm qhov kev hloov ntawm cov tshav kub cuam tshuam cheeb tsam (HAZ) thiab cov ntaub ntawv ib puag ncig, thiab xyuas kom meej tias cov ntaub ntawv yuav tsis deformed los ntawm tshav kub Cov.
Kev ua txias txias (duab hluav taws xob) photons nrog lub zog thauj khoom hnyav tuaj yeem tsoo cov ntawv cog lus tshuaj hauv cov ntaub ntawv (tshwj xeeb yog cov ntaub ntawv organic) lossis cov xov xwm ib puag ncig, ua rau cov txheej txheem tsis-thermal ua puas tsuaj ntawm cov khoom. Qhov kev ua haujlwm txias no yog qhov tseem ceeb tshwj xeeb hauv cov cim laser ua kev lag luam, vim tias nws tsis yog thermal ablation, tab sis theej tsis tsim txau txias uas yog pab los ntawm "thermal puas tsuaj" thiab rhuav cov ntawv sib raug zoo. Yog li, nws tsis cuam tshuam rau sab hauv txheej thiab qhov chaw ze ntawm txheej txheej txheej txheej txheej txheej txheej txheej txheej. Tsim kom muaj cua sov lossis cua sov deformation.
Vim tias cov cua sov ua los ntawm cov txheej txheem kub dhau los yuav ua rau muaj kev puas tsuaj rau sab nraud thiab nruab nrab ntawm lub npog ntsej muag, uas yuav muaj kev cuam tshuam ntau dua ntawm qhov tsis huv ntawm lub npog ntsej muag, qhov "ua txias" UV laser siv los cim qhov chaw ntawm lub npog ncauj.
