Cov ntaub paj rwb ntshiab tuaj yeem tiv thaiv hluav taws xob zoo li qub?
Feem ntau nws ntseeg tias hnav cov paj rwb tuaj yeem tiv thaiv kev tsim hluav taws xob zoo li qub hauv cov khaub ncaws, yog li nws muaj kev nyab xeeb. Qhov tseeb, qhov kev pom no yog ib leeg xwb. Qhov no yog qhov xwm txheej tsuas yog thaum cov huab cua txheeb ze huab cua siab dua 50%; thiab thaum cov txheeb ze cov av qis dua, tus nqi ntawm cov khoom paj rwb ntshiab nce ntau. Kev ntsuam xyuas tau qhia tias thaum cov av noo txheeb ze qis dua 30%, kev them nqi ntawm cov ntaub paj rwb ntshiab yog sib npaug ntawm polyester; thiab thaum cov txheeb ze cov av qis dua 20%, tus nqi ntawm cov paj rwb ntaub tseem siab dua li ntawm qee cov tshuaj fiber ntau. Yog li ntawd, hauv thaj chaw huab cua qhuav, peb tsis tuaj yeem cia siab tias yuav siv cov khoom siv paj rwb ntshiab los tshem tawm qhov hluav taws xob zoo li qub ntawm cov khaub ncaws hauv txhua qhov xwm txheej.
Raws li cov laj thawj saum toj no, txhawm rau txhawm rau tiv thaiv qhov teeb meem hluav taws xob tawm ntawm tib neeg lub cev hluav taws xob zoo li qub, tus neeg teb xov tooj yuav tsum hnav khaub ncaws ua haujlwm zoo li qub.
Kev txhim kho keeb kwm ntawm cov pa roj carbon zoo li qub
Cov organic fiber ntau tau tsim nyob rau xyoo 1960s. *Cov organic ua kom muaj fiber ntau coated nrog cov pa roj carbon thiab dub yog thawj qhov uas tawm los. Teijin thiab BASF tau ua tiav kev tsim cov xov paj zoo li no. Cov khoom siv hluav taws xob ntawm cov pa roj carbon-coated conductive fiber tau faib rau saum cov fiber, yog li kev ua tau zoo yog qhov zoo, tab sis cov pa roj carbon dub tau yooj yim poob tawm thaum cov fiber ntau rub los yog khoov, thiab qhov ua tau zoo yuav yog txo. Dab tsi ua raws yog cov hluav taws xob ua hluav taws xob coated nrog hlau saum npoo. Rohm thiab Haas siv cov plua plav tsis huv rau plating nyiaj rau ntawm cov nplaim hluav taws xob nylon los ua cov hluav taws xob muaj hluav taws xob X-Static, thiab Toyobo siv cov hlau kub uas tsis tshua muaj kub los ua kom nws ua kom muaj fiber ntau nrog cov tawv nqaij. Statex' s Ex-Stat siv cov tshuab tsis muaj nyiaj plating thev naus laus zis los ua cov khoom siv hluav taws xob. Cov xaim hluav taws xob nrog cov hlau fiber ntau qhov chaw muaj qhov sib txawv loj hauv cov khoom siv los ntawm cov fibers zoo tib yam, uas ua rau sib xyaw nyuaj dua, yog li lawv tsis tau siv dav.
Xyoo 1975, Du Pont tau siv cov tshuab thev naus laus zis los ua Antron III cov khoom siv sib xyaw ua ke uas muaj cov pa roj carbon dub coj ua. Txij thaum ntawd los, cov tuam txhab hluav taws xob hluav taws xob loj tau pib tshawb fawb thiab tsim cov fibers sib xyaw uas siv cov pa roj carbon dub los ua cov khoom siv. Ib sab ntawm ib sab Utron cov khoom siv hluav taws xob tsim los ntawm Monsanto, Belltron nylon conductive fiber tsim los ntawm Kanebo, Megana III conductive fiber tsim los ntawm Unijika, Kuracarbo ntawm Kuracar, thiab cov khoom siv hluav taws xob ntawm Toyobo KE-9, thiab lwm yam, ua rau cov pa roj carbon dub sib xyaw ua kom muaj fiber ntau tau nthuav dav. Txog qhov kawg ntawm xyoo 1980s, txhua xyoo cov pa roj carbon dub sib xyaw ua ke hauv Nyij Pooj tau txog 200 tons. Txawm li cas los xij, vim tias cov pa roj carbon dub sib xyaw ua kom muaj fiber ntau siv cov dub dub ua cov khoom siv sib txuas, cov fiber ntau feem ntau yog xim dub-dub, thiab nws cov ntawv thov muaj txwv.
Kev tshawb fawb ntawm kev ua kom dawb ntawm cov kab hluav taws xob tau pib xyoo 1980s. Feem ntau siv txoj hauv kev yog siv tooj liab, nyiaj, npib tsib xee, cadmium thiab lwm yam hlau sulfides, iodides lossis oxides nrog cov polymers zoo tib yam los sib xyaw lossis sib xyaw ua ke kom ua cov kab hluav taws xob. Piv txwv li, Rhone-poulence Lub Tuam Txhab siv tshuaj lom neeg los ua Rhodiastat conductive fiber nrog CuS conductive txheej; Teijin Lub Tuam Txhab ua cov khoom siv hluav taws xob T-25 nrog Cul ntawm qhov chaw; Kanebo Tuam Txhab ua ZnO2 conductive Belltron632 thiab Belltron638; Lub tuam txhab Unijika txhim kho Megana. Cov khoom siv hluav taws xob ntawm cov hluav taws xob ua hluav taws xob siv cov hlau sib txuas lossis cov hlau oxide raws li cov khoom siv hluav taws xob tsis zoo dua li cov pa roj carbon dub sib xyaw ua ke. Tab sis nws daim ntawv thov tsis cuam tshuam los ntawm xim.
Kev tshawb fawb hauv tsev thiab kev txhim kho cov khoom siv hluav taws xob tau lig dhau lawm. Kev tsim cov hlau hlau thiab carbon fiber tau pib xyoo 1980s, tab sis cov khoom tsim tawm tau tsawg heev. Cov hlau hlau xws li cov hlau tsis xeb hlau tau siv dav hauv cov khaub ncaws tiv thaiv tshwj xeeb xws li cov khaub ncaws ua haujlwm roj thiab khaub ncaws ua haujlwm tiv thaiv. Nyob rau xyoo tsis ntev los no, ntau yam ntawm cov organic conductive fibers tau ua tiav tsim hauv Suav teb. Piv txwv, metallized PET conductive fiber nrog Cu thiab Ni plated rau saum npoo, CuI conductive acrylic conductive fiber, CuI/PET blended conductive fiber, carbon black composite conductive fiber thiab ntxiv rau. Cov khoom siv hluav taws xob saum toj no tau ua lag luam cov khoom lag luam, tab sis vim muaj cov khoom lag luam qis thiab tsis ruaj khov zoo, tus nqi siab dua li cov khoom lag luam txawv teb chaws zoo sib xws.
Coated thiab composite organic conductive fibers muaj cov khoom siv lub cev thiab cov khoom siv tau zoo thiab tiv taus tshuaj lom neeg, uas tuaj yeem hloov kho rau cov ntawv textile dyeing thiab ua tiav cov txheej txheem, thiab muaj cov xim zoo. Pure polyester dawb weave npuag muaj cov tshuaj tiv thaiv zoo tom qab ntxiv cov xov paj hauv cov xov hauv ib txoj kev, thiab muaj kev ua haujlwm zoo heev.
Lub cev thiab cov cuab yeej siv yooj yim ntawm cov khoom siv hluav taws xob zoo ib yam li cov xov paj rwb zoo tib yam, nrog tshuaj zoo tiv taus thiab zas xim, thiab muaj peev xwm ua tau ntev. Ntxiv cov tshuaj fiber ua rau cov ntaub yuav tsis cuam tshuam rau qhov xav thiab ci. Lub Tsib Hlis 1, xyoo no, 99-style tsho tshiab tsim los ntawm Cov Neeg Suav' Pab Pawg Liberation tau txais cov organic fiber ntau ua cov khoom siv tiv thaiv kab mob. Kev xyaum tau ua pov thawj tias cov txiaj ntsig tau zoo.
Cov khoom siv hluav taws xob siv hluav taws xob tau siv hauv kev tiv thaiv zoo li qub ntawm cov khaub ncaws thiab ntaub pua tsev. Nws kuj tseem tuaj yeem siv dav hauv kev tiv thaiv zoo li qub, tiv thaiv plua plav thiab tawg-pov thawj cov khaub ncaws ua haujlwm uas yuav tsum tau muaj hauv kev lag luam semiconductor, kev lag luam hluav taws xob, kev kho mob engineering, engineering engineering thiab lwm yam haujlwm; siv hluav taws xob tiv thaiv hluav taws xob tiv thaiv thiab nqus cov ntaub ntawv, cov khoom cua sov ntawm cov khoom siv hluav taws xob cua sov, thiab cov khoom siv lim dej.
