Yuav ua li cas xaiv cov hnab looj tes tiv thaiv thiab cov hnab looj tes tiv thaiv qub
Kev tiv thaiv tes yog ib qho tseem ceeb tshaj plaws thiab cov kabmob hauv tib neeg lub cev. Nws muaj 27 pob txha, txhawm rau 1/4 ntawm tag nrho cov tib neeg cov pob txha, thiab kev faib thiab kev koom tes ntawm cov leeg, cov hlab ntsha thiab cov neeg nquag yog qhov tsis sib haum. Tsuas yog qhov ntev ntawm lub capillary ib square centimeter ntawm lub ntsis ntiv tes tuaj yeem nkag mus txog ntau lub hli. Muaj ntau txhiab hnub. Cov kev nplua neural tes hauj lwm no cia peb pom tias txias, cua sov, mob, thiab lwm yam hauv ob peb lub microseconds, thiab txawm hnov cov vibrations uas yog me me li cov kab plaub hau. Txij thaum hnub yug, txhais tes tsis tau nres qhov kev ua si, thiab thaum kawg ntawm lub neej, tes yuav txav thaj tsam ntawm 250 lab zaug. Txawm li cas los xij, peb pheej tsis nco qab txog qhov tseem ceeb ntawm tes thiab tsis quav ntsej txog kev tiv thaiv kom zoo, yog li ntawd raug mob ntawm tes raug 20% ntawm txhua yam kev ua haujlwm raug mob. Qhov no qhia tias cov kev xaiv kom yog thiab siv cov khoom siv tiv thaiv yog tsim nyog. Qhov kev raug mob ntawm tes yuav muab faib ua peb pawg ntawm qhov loj: 1. Kev raug mob ntawm tes xws li kev raug mob hnyav vim yog kev raug mob rau cov pob txha, cov leeg nqaij lossis cov nqaij thiab cov khoom, los ntawm cov ntiv tes loj heev thiab tawg. Mus rau ib tug me ntsis kev raug mob rau cov nqaij thiab zoo li. Yog tias koj siv lub cuab tam ua ntu, siv cov tshuab qaum lossis cov khoom siv nrog riam, lub tswv yim, thiab lwm yam, yuav ua rau tes txiav, thiab lwm yam. Kev siv, ntxaiv, ntsia hlau, txhauv, xov, thiab lwm yam. Thaum twg koj yob mus rau hauv lub tshuab, koj tuaj yeem yob mos, zuaj, los sis tseem ntog koj cov ntiv tes. 2. Hu rau dermatitis Hom kab mob no feem ntau yog tshwm sim los ntawm kev puas tsuaj ntawm daim tawv nqaij ntawm tus neeg sib tw lub ntsej muag. Lub teeb, ua rau ntawm daim tawv nqaij qhuav, chiv, khaus, hnyav liab liab, hlwv, herpes, crusting thiab thiaj li. Kev tsim ntawm hom kev raug mob no yog raug mus rau acid, alkali aqueous solutions, detergents, disinfectants, etc., los yog raug ntau cov tshuaj lom thiab tshuaj lom neeg, raug kev txom nyem los ntawm hluav taws xob shock, tsis kub kub, kub kub, nplaim taws kub hnyiab, thiab lwm yam. 3. Caj npab shake syndrome, tus ntiv tes dawb ntiv tes thiab lwm qhov kev siv ntev ntawm cov cuab yeej siv tes ua, xws li chainsaws, pob zeb xyaum, hluav taws xob, pneumatic picks, thiab lwm yam. Thaum cov tes vibrates nrog lub cuab tam rau ib lub sij hawm ntev, nws yuav tseem ua kev puas tsuaj rau cov ntshav ncig, thiab dawb ntiv tes syndrome tshwm sim. Qhov no yog qhov tseeb tshwj xeeb tshaj plaws hauv cov chaw ntub dej txias thiab txias. Vim cov neeg pluag tsis zoo, cov tes ua daj, loog, thiab cov zoo li. Yog tias koj ua rau hnov qab lub hlwb, koj txhais tes xis ua rau kub kub, qhov kov yuav ploj mus, thiab tseem muaj peev xwm nyob taus. Cov hnab looj tes ua rau muaj kev phom sij ntau rau hauv chaw ua haujlwm, koj tuaj yeem xaiv ntau hom hnab looj tes, xws li cov hnab looj tes tivthaiv, tshuaj tiv thaiv kabmob rau cov khoom hluav taws xob, cov hnab yas thiab kub tsis kub, cov hnab looj tes tiv thaiv kev vibration rau kev ua hauj lwm, thiab lwm yam. Cov khoom siv ntawm cov hnab tes taw txiav txim siab txog kev tiv thaiv ntawm cov hnab looj tes thiab yog lub hauv paus rau cov khoom siv hnab looj tes. Ntawm no yog qee cov khoom siv looj xws li: 1. Hnab looj rau cov khoom puas tsuaj: xaim - hom hlau tsis xeb hlau, thiab chrome hlau, feem ntau yog siv los ua hnab looj tes rau tawv nqaij. Cov ntaub ntawv no muaj kev tiv thaiv ntau tshaj plaws thiab yooj yim los ntxuav, tiam sis lawv hnyav thiab tsis zoo siv. Kevlar, Spectra thiab lwm yam khoom cua hluavtaws kuj zoo dua cov khoom siv hluav taws xob txiav tawm-resistant, tab sis kev txiav tawm tsis zoo li ntawm cov hlau. Lub teeb, zoo siv, thiab kho thiab kho, qee cov khoom kuj muaj peev xwm ua kom tau raws li cov qauv siab tshaj plaws ntawm cov khoom uas txiav cov khoom ntuag; nitrile (nrog ntaub phiv) - tiv taus hnav thiab hno, yoog thiab nyiam siv; natural latex (Nrog rau ntaub qhwv quav) - zoo heev elasticity, tshwj xeeb tshaj yog hloov tau, nrog rau ib theem ntawm kev tsis kam hnav, rhuav thiab txiav; PVC (nrog ntaub phuam) - muab tau qee qhov hnav thiab thaiv kev tiv thaiv, yog tias cov khoom yog thicker thiab tuaj yeem muaj peev xwm hlais, tab sis nws tsis ua rau tearing; ntawm daim tawv nqaij - tej khoom siv, muaj kev ua tau zoo los ntawm ntau cov kev kho tanning. Cov tawv nqaij tau muab faib ua: cov cowhide, nws qhov zoo yog xis, ruaj, breathable thiab hnav-resistant, chrome-kho, ntau ruaj, thiab resistant mus rau high kub; pigskin, qhov loj pores, zoo tshaj plaws txog kev ua pa, tuaj yeem ua tau zoo tom qab ntxuav Softness tsis tawv; sheepskin yog qhov zoo tshaj plaws, ruaj thiab txeeb resistant, tab sis vim nws kim heev, nws feem ntau tsuas yog siv nyob rau hauv cov lag luam uas kov qhov siab. 2. Cov khoom kub hnyav rau cov khoom kub: Cov tshuaj pleev kom tshiab - Novoloid - ib yam tshiab ntawm cov khoom siv hluav taws xob hluavtaws, tsis muaj melting, nplaim taws, kub kub, 1100 ° C, muag thiab xis, thiab tiv taus ntau yam tshuaj , txawm tias tom qab ua Kev Ntxuav tas yuav tsis cuam tshuam rau nws qhov kev kub ntxhov siab; Kevlar yog ib qho siv ntau hom hluavtaws hluavtaws uas tsis yog tsuas yog kev thim tawm tabsis tseem muaj kev kub ntxhov siab; aluminized khoom - muaj peev xwm tawm tsam kub kub radiant kub; - Yog hais tias nws qhuav, nws muaj qhov kub tsis zoo. Nyob rau tib lub sijhawm, nws cov khoom uas tsis yog nqaij ntuag thiab tsis kub hnyiab ua rau nws siv los ua hluav taws xob welding looj. Paj rwb kuj tseem yog ib qho khoom siv uas yuav pab tiv thaiv tau kub thiab tsis tshua muaj qhov kub. Txawm li cas los xij, vim muaj kev tiv thaiv, cov hnab looj tes tau ua kom tuab thiab qhov yooj yim tsis zoo txaus. 3. Hluav taws xob tiv thaiv hluav taws xob thaiv hniav looj hnab looj tes rau hluav taws xob kev puas tsuaj yog tsim tshwj xeeb tsim thiab txhuam xyuas kom ntseeg tau tias muaj kev ruaj ntseg. Feem ntau cov hnab looj fais looj hluav taws xob tau ua los ntawm cov khoom siv roj ntsha. Cov txheej txheem muab faib ua ob hom: kua nplaum thiab kua nplaum ntub dej. Insulating hnab looj tes ua los ntawm ntub kua nplaum muaj qhov ua tiav ntev thiab cov nqi ntau lawm, tab sis cov khoom elasticity ntawm qhov khoom yog zoo heev thiab kev siv yog heev yooj ywm. Tsis tas li ntawd xwb, vim muaj kev tshwj xeeb ntawm kev ua haujlwm thiab cov yam ntxwv ntawm cov cuab yeej hluav taws xob hauv lawv tus kheej, thaum hnav looj hnab looj tes, thawj zaug hnav cov hnab looj tes (lub hws, cov ntawv pov npav), tom qab muab hnab looj tes yas, thiab thaum kawg siv tiv thaiv epithelial. Cov hnab looj tes los tiv thaiv tho hnab looj tes los ntawm cov khoom ntse. 4. Cov hnab looj cov tshuaj tiv taus Cov tshuaj muaj yees muaj ntau yam sib txawv. Cov xim tshwj xeeb yuav tsum them rau xaiv cov hnab looj cov tshuaj uas tiv taus: natural latex - feem ntau, natural latex muaj ib qho kev tiv thaiv zoo rau cov dej daws aqueous xws li acid thiab alkali aqueous solutions. . Nws qhov zoo yog kev nplij siab, yooj yim thiab yooj yim; nitrile - nws muaj kev tiv thaiv zoo tiv thaiv cov tshuaj roj, greases, petrochemicals thiab lubricants thiab ntau cov kuab tshuaj. Txawm li cas los xij, hauv qee cov kuab tshuaj, o yuav ua rau nws lub cev nqaij daim tawv thiab txo nws txoj kev tiv thaiv. Polyvinyl chloride - muaj kev tiv thaiv ntau ntawm cov dej-soluble tshuaj, xws li cov kua qaub thiab cov hauv paus, tab sis tsis tuaj yeem tiv thaiv cov tshuaj xws li cov kuab tshuaj vim tias ntau cov kuab tshuaj yuav ua kom cov yas lim, tsis tas yuav ua kom muaj kuab paug,
