Cov txheej txheem molding ntawm kub panning pam ncaj qha txiav txim siab lawv cov kev ua tau zoo thiab kev pabcuam lub neej, sawv cev rau cov kauj ruam tseem ceeb hauv kev hloov cov ntaub ntawv raw rau hauv cov khoom siv tshwj xeeb lub cev thiab microstructure. Cov txheej txheem encompasses ntau cov kauj ruam, nrog rau kev xaiv fiber ntau, weaving txoj kev, nto napping, thiab finishing.Txhua kauj ruam yuav tsum sib npaug txhua yam lub zog, puas thiab corrosion kuj, thiab kub grain capture muaj peev xwm ua tau raws li cov kev cai nruj ntawm placer kub enrichment kev khiav hauj lwm.
Kev xaiv raw khoom yog qhov tseem ceeb rau molding. Feem ntau siv fibers muaj xws li siab -toughness hluavtaws polyester, polypropylene, thiab qee yam ntuj abrasion- cov fibers tiv taus. Cov ntaub ntawv no muaj kev tiv thaiv zoo heev rau hydrolysis, UV hluav taws xob, thiab xuab zeb abrasion. Kev xaiv cov khoom siv yuav tsum tau ua kom haum rau lub hom phiaj kev ua haujlwm ib puag ncig cov dej pH, qhov kub thiab txias, thiab cov xuab zeb hardness kom ntseeg tau tias cov fibers tsis muaj kev laus los yog tawg thaum lub sij hawm ntev - siv. Rau cov xwm txheej uas xav tau cov khoom siv abrasive siab, cov fibers sib xyaw lossis cov txheej txheem txheej txheej tau qhia los txhim kho thawj zaug puas.
Cov txheej txheem weaving txiav txim siab cov qauv yooj yim thiab kev ruaj ntseg ntawm daim pam. Cov txheej txheem siv feem ntau yog warp-weft interlacing lossis warp knitting voj weaving. Cov yav tas los pab txhawb kev tsim cov mesh tsis tu ncua rau kev tsim cov pawg tom ntej, thaum lub tom kawg txhim kho cov ntaub pua plag elasticity thiab adhesion thaum tuav lub zog. Lub weaving ceev yuav tsum tau teem raws li qhov xav tau ntau ntawm cov khoom kub qhov ntau thiab tsawg yuav tsum tau ntes - tuab heev yuav txo cov dej permeability thiab ua rau muaj kev pheej hmoo ntawm clogging, thaum sib sib zog nqus heev yuav ua rau cov neeg kho tshuab tsis muaj zog rau cov khoom kub zoo. Lub kaw lus tswj nruj ua lub luag haujlwm tseem ceeb hauv cov txheej txheem weaving, kom ntseeg tau tias muaj kev ntxhov siab fiber ntau thiab tiv thaiv kev xoob hauv zos lossis deformation.
Kev tsim cov pob zeb saum npoo yog cov kauj ruam tseem ceeb uas txiav txim siab qhov ua tau zoo ntawm cov ntaub pua plag kub panning. Los ntawm kev siv tshuab rab koob punching, hydroentangling, los yog huab cua kub napping, ib txheej tuab thiab uniformly oriented pawg yog tsim rau ntawm cov ntaub pua plag. Cov pawg qhov siab thiab qhov sib faib ntom ntom yuav tsum tau sim kuaj xyuas kom ntseeg tau tias nws tuaj yeem ntsuas cov khoom kub tsis muaj kev cuam tshuam cov dej thiab cov xuab zeb sib sib zog nqus. Cov theem no yuav tsum muaj kev tswj xyuas qhov tseeb ntawm cov txheej txheem tsis xws li rab koob punching zaus, qhov tob, thiab ntaub taug kev ceev; Txawm tias me ntsis sib txawv tuaj yeem ua rau txo qis hauv kev ntes tus nqi lossis lub neej ntawm cov ntaub pua plag luv.
Tshaj tawm - kev ua haujlwm suav nrog kev teeb tsa cua sov, stains thiab dej tshuaj tiv thaiv, thiab kev txhawb nqa ntug. Thaum tshav kub kub tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sij hawm xaws thiab pw tsaug zog, tswj qhov seem stability ntawm cov ntaub pua plag; ib tug stain{2}}resistant thiab waterproof txheej txo cov av nkos thiab xuab zeb adhesion thiab fiber ntau o, txhim kho kev tu efficiency thaum lub sij hawm ua hauj lwm; ntug reinforcement, los ntawm kev khi los yog xaws abrasion- daim kab xev resistant, tiv thaiv delamination thiab kev puas tsuaj los ntawm nquag tuav thiab tso.
Zuag qhia tag nrho, cov txheej txheem kub panning ntaub pua plag tsim yog ib qho kev tsim vaj tsev tsim ua ke nrog cov ntaub ntawv tshawb fawb, textile engineering, thiab ntxhia sorting mechanisms. Nws lub ntsiab lus yog nyob rau hauv kev hloov lub cev lub cev ntawm fibers mus rau hauv microstructure nrog kev taw qhia kev ntxiab muaj peev xwm los ntawm ntau- txheej txheem kev sib koom tes, ua kom cov khoom tiav kom muaj txiaj ntsig zoo thiab ruaj khov sorting kev ua tau zoo txawm nyob rau hauv complex ntxhia thiab dej ntws ib puag ncig. Cov txheej txheem tsim cov txheej txheem no tsis tsuas yog lav cov khoom zoo tab sis kuj yog lub hauv paus txheej txheem thev naus laus zis rau cov nqi txuas ntxiv ntawm cov ntaub pua plag kub panning hauv thaj chaw ntawm placer kub enrichment.
