Antistatic textiles - ntxhua khaub ncaws
Tus nqi hluav taws xob electrostatic thiab feem cuam tshuam kev puas tsuaj los ntawm cov khoom siv hluav taws xob thiab tshuab hluav taws xob hluav taws xob hluav taws xob yog cov ntxhuav heev. Nws raug paub los ntawm kev txheeb xyuas tias txhua xyoo kev puas tsuaj los ntawm Electrostatic Discharge (ESD) yog kwv yees li $ 900 lab. Qee cov kws txawj ntseeg hais tias qhov tseeb yuav raug ntau dua. Yog li, qhov yuav tsum tau thiab qhov zoo ntawm cov khoom tiv thaiv ib puag ncig (chav tu huv) yog nyob rau qhov nce.
Vim tias huab cua nyob rau hauv chav tu huv feem ntau yuav tsum tau ceev cia rau hauv lub xeev qhuav ntawm 45% kwv yees voom, nws yooj yim rau tsim hluav taws xob; muaj ob lub hom hluav taws xob hluav taws xob nyob rau hauv cov txheej txheem hluav taws xob, ib qho yog qhov ua kom muaj cov pa phem, hauv cov chav sib txawv. Qhov thib tsib feem ntawm qhov chaw muaj pa phem, kwv yees li 5%, lwm qhov yog electrostatic discharge (ESD), uas ua rau tus nqi tsis ua hauj lwm, uas yog thawj qhov chaw nyob hauv cov khoom tsis ntxov ntxov ntawm cov khoom, tshaj 50%; kom txhawm rau kov cov electrostatic discharge Qhov teeb meem, ntau lub tuam txhab tau pib kawm ntau yam kev tswj kev tswj ntawm qhov nruab nrab, nrog rau lub cuab yeej tshuab thiab cov khoom hluav taws xob uas tsim los ntawm tib neeg lub cev.
(2) tsis muaj peev xwm ua kom muaj cov hmoov txhuam hniav zoo (tsis muaj pes tsawg tiam), (3) lub cev muaj zog txaus, thiab (4) lub cev muaj zog, (5) tsis ua hauj lwm rau tej chemicals thiab (6) hnav kev nplij siab thiab lwm yam ntxwv.
Tam sim no, cov khaub ncaws tsis muaj kab mob thiab tsis muaj plua tshauv feem ntau yog khaus ntawm cov fibers ntev ntev. Cov ntaub ntawv no tuaj yeem ua rau khov khov khov rau hauv ib rab knitted, txhuam los yog qov ncauj. Polyester ntev fiber yog qhov tseem ceeb raw khoom rau kev ntxuav chav tsev. Txhawm rau kom muaj kev ruaj siab ruaj khov rau ntawm cov ntaub npog, nws yog feem ntau nyob rau hauv txheej txheem weaving (feem ntau 0.1% 0.5% ntawm qhov hnyav ntawm cov ntaub) ntawm cov xov tooj hluav taws xob. Cov khoom siv hluav taws xob no feem ntau yog nyob rau hauv daim ntawv strips lossis grids ntawm cov ntaub ntawv tiav (3-10 hli, nyob ntawm qhov kawg siv).
Muaj ntau hom tshuaj antistatic fibers muaj nyob hauv kev ua lag luam. Cov phuam ntawm cov fibers no feem ntau yog ua los ntawm kev ntxiv cov khoom siv me me rau cov khoom siv fiber ntau, uas yog tau los ntawm ob txoj hauv kev:
1. Cov organic polymer fiber (mas polyamine lossis polyester)
(a) Ntxiv cov khoom siv tshuaj yeeb dej caw (xws li carbon carbon) thaum lub sij hawm qhuav tawg.
(b) Tom qab qhuav tas, ib yam khoom siv yog siv los ua fiber ntau rau kev kho mob.
2. Inorganic fiber (xws li cov hlau tsis muaj fiber ntau): Cov cwj pwm fais fab yuav tsum tau muab khi rau hauv daim ntaub ntawv tom qab tig. Cov khoom siv hluav taws xob yuav tsum muab kho raws li hom, qhov ntau thiab qhov chaw ntawm cov khoom siv hluav taws xob. Cov fib fib fais fab yog cov khoom siv uas siv ntau tshaj plaws. Cov ntaub ntawv, tooj liab sulphide, tooj liab iodide thiab lwm cov pa oxidized kuj feem ntau siv. Cov khoom siv hluav taws xob yuav tsum tau coated rau txheej txheej txheej ntawm fiber ntau los ntawm cov txheej txheem txheej txheem zoo ib yam, los yog cov nplaum hluavtaws yuav siv los ua hauv fiber ntau muaj cov khoom siv, lossis ib feem ntawm qhov chaw yuav muab faib rau ntawm qhov chaw ua ob hom kev tshaj tawm hauv cov fiber, thiab cov khoom siv hluav taws xob feem ntau Tus nqi ntxiv yog 3% thiab 30%.
