Polypropylene MlT Tshuab Tsis Yog - Woven Fabrical ntau lawm
Qhuav tshuab newwoven npuag
Lub ntsiab
Cov qhov ncauj sib txawv lossis qib ntawm cov khaub ncaws tiv thaiv thiab cov qauv ntawm cov khaub ncaws sib txawv (peb mus rau ntawm cov ntaub qhwv siab tshaj plaws, peb mus rau cov ntaub qhwv uas tsis yog-woven, yog dab tsi sms lossis smmms sib xyaw.
Qhov tseem ceeb tshaj plaws ntawm cov cuab yeej tiv thaiv yog lub txheej txheem barrier, nam los xij-woven txheej ntawm kev tiv thaiv lub infiltration cov kab mob thiab cov ntshav Cov. Lub microfiber daim ntaub lim zoo qhia lim, huab cua permeability thiab adsorbility, yog li nws yog siv dav, cov khoom siv cua sov thiab kev nyiam kho mob thiab lwm daim teb.
Polypropylene MlT Blown Tsis Yog - Woven Npuag Ntau Lawm Tshuab thiab cov txheej txheem
Cov txheej txheem tsis-Woven Fabric ntau lawm feem ntau yog cov twj tso kua mis tau muab tso rau → Vaub Ilistrusion → mipt →
Lub hauv paus ntsiab lus ntawm cov txheej txheem melting yog kom extrude polymer yaj los ntawm lub taub hau spinneret los ua ib qho dej ntws ntawm yaj. Nyob rau tib lub sijhawm, lub siab-nrawm thiab kub-huab cua ntws ntawm ob sab spinet kwj, uas yog ces ua kom zoo rau cov filaments nrog ib tug zoo ntawm tsuas yog 1 ~ 5μm. Cov filaments no tau rub mus rau luv luv cov hmoov av txog li 45 hli los ntawm thermal ntws.
Txhawm rau tiv thaiv cov cua kub los ntawm tshuab cov tshuab fiber ntau, lub tshuab nqus tsev sib xyaw ua ke los ntawm kev siv cov pa hluav taws xob kub. Thaum kawg, nws tso siab rau tus kheej-nplaum kom ua rau yaj-tshuab tsis muaj ntaub npuag.
Cov txheej txheem tseem ceeb:
Cov khoom siv ntawm polymer raw: suav nrog cov khoom siv raw, cov ntsiab lus tshauv, feem ntau yog hais tawm los ntawm Melting Performance index (MFI). Qhov ntau dua MFI, qhov zoo dua cov lus melt fluidity ntawm cov khoom, thiab hloov ua lwm yam. Qhov qis dua cov molecular hnyav ntawm cov khoom cob qhia, lub siab dua MFI thiab qis dua qhov ntau melt viscosity, qhov ntau dua haum rau cov txheej txheem melt buttercosity, qhov ntau dua rau cov txheej txheem melt chorkout nrog kev sau ntawv tsis zoo. Rau polypropylene, MFI yuav tsum muaj nyob rau hauv ntau ntawm 400 ~ 1800g / 10min.
Nyob rau hauv cov txheej txheem ntawm melt tshuab luam yeeb tsim khoom, cov tsis hloov kho raws li qhov kev thov ntawm cov khoom raw thiab cov khoom lag luam tsuas yog suav nrog:
(1) Melt Extrusion kom muaj nuj nqis thaum qhov kub yog tas mus li, lub zog ua kom muaj nuj nqis ntxiv, thiab lub zog nce ntxiv (txo qis tom qab ncav cuag tus nqi ncov). Nws txoj kev sib raug zoo nrog lub zog sib zog ua kom tiav, cov kab zauv txo qis, ua rau lub zog ntawm cov nplais ntawm cov ntaub ntawv tsis zoo Cov.
(2) qhov ntsuas kub ntawm txhua thaj chaw ntawm cov ntsia hlau tsis yog tsuas yog cuam tshuam nrog txoj kev tawg paj, tab sis kuj cuam tshuam cov tsos mob, xav thiab ua haujlwm ntawm cov khoom. Qhov kub thiab txias dhau lawm, yuav muaj "thaiv" thaiv daim ntaub, tawg fiber ntau nce ntxiv, tshwm sim "ya". Cov teeb meem tsis zoo yuav ua rau txhaws ntawm lub taub hau sprinkler, hnav tawm lub qhov muag spinneret, thiab puas cov cuab yeej.
(3) Ncab cov cua kub kub ncab kub huab cua kub yog feem ntau qhia los ntawm huab cua kub (siab), muaj qhov kev cuam tshuam ncaj qha rau lub fiber. Nyob rau hauv cov ntaub ntawv ntawm lwm yam tsis sib xws, ua kom muaj kev ceev ntawm huab cua kub, fiber ntau, lub zog ua kom muaj zog, tsis yog-woven xav ua mos thiab du. Tab sis qhov nrawm yog loj heev, yooj yim kom pom "ya", cuam tshuam rau cov tsos ntawm cov ntaub tsis-woven; Nrog rau kev txo qis ntawm cov ceev, lub porosity nce ntxiv, cov kev ua kom pom kev txo qis, tab sis kev ua kom pom kev ua kom tsis pom kev. Nws yuav tsum tau sau tseg tias cov cua kub kub yuav tsum tau nyob ze rau melt kub, tsis muaj Airflow yuav tsim thiab lub thawv yuav raug puas.
(4) yaj qhov kub yaj kub, tseem hu ua Maut taub hau kub, yog ze rau melt fluwsity. Nrog rau qhov nce ntawm qhov kub thiab kub ua tau zoo dua, lub fiberity txo, cov fiber ua kom zoo nkauj thiab cov khaub ncaws hnav zoo dua. Txawm li cas los xij, qhov qis dua viscosity, zoo dua, muaj kuab heev, fiber ntau yooj yim tawg, microfiber ya dav hlau ya hauv huab cua tsis tuaj yeem sau.
(5) Tau txais kev deb tau txais kev deb (DCD) yog hais txog qhov kev ncua deb ntawm spinneret thiab mesh kab hlau rhuav. Qhov ntsuas no tau muaj feem cuam tshuam tshwj xeeb ntawm lub zog ntawm cov ntxaij fiber ntau. Nrog rau qhov nce ntawm DCD, lub zog thiab khoov txhav zuj zus zuj zus, cov pliav fiber ntau ntxiv lawm, thiab qhov sib txuas lus sib raug zoo. Yog li ntawd, cov tsis-woven npuag yog muag thiab fluffy, lub ermeagility nce ntxiv, thiab kev siv hluav taws xob tsis kam ua kom tsawg. Thaum qhov kev ncua deb yog ntau dhau, cov cua ntsawj ntshaus tau txo los ntawm huab cua kub tau tshwm sim los ntawm cov fibers nyob rau hauv cov txheej txheem ntawm kev sau duab, uas ua rau filaments. Thaum tau txais kev deb yog qhov tsawg dhau, cov fiber tsis tuaj yeem txias, ua rau hauv xaim, tsis-woven npuag lub zog txo qis, ua kom huv.
