Txhaum Kev Ntsuam Xyuas thiab Kev Tiv Thaiv Cov Kev Tawm Tsam ntawm Cov Txheej Txheem Soj Ntsuam
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Ib qhov zoo tshaj plaws yog tsis yooj yim rau ua rau kev tsis sib haum, kev xav txog ntau yam. Kev siv tsis muaj hluav taws xob, uas yog qhov nyuaj tshaj plaws los piav txog feem ntau ntawm cov ntawv luam tawm, tshwj xeeb tshaj yog qhov tshwm sim ntawm ntau hom ntawv luam thiab kev nrhiav kev kub ceev, qhov tshwm sim no tshwm sim ntau dua. Electrostatics yog pab pawg neeg tsawg tshaj plaws, them nqi, them nqi thiab them, stripped thiab them, phom nrov thiab them, thiab ua rau agitated thiab them. Qhov kev sib raug zoo tshaj nrog kev luam tawm yog triboelectric them nyiaj, ntws them nqi thiab stripping them. Muab piv rau lwm hom kev ua haujlwm, luam tawm tau hais tias yog ib txoj hauj lwm yooj yim los ua hluav taws xob zoo. Nyob rau yav tom ntej, kev tshawb fawb txog kev tiv thaiv tawm tsam hluav taws xob hauv hluav taws yuav ua ib qhov kev tswj kav tseem ceeb.
Hauv cov ntawv nyeem gravure, lub ntsiab ua rau hluav taws xob zoo yog:
1. Kev sib tw ntawm huab cua thiab zaj duab xis;
2. Txhuam thiab tawg ntawm zaj duab xis thiab qhia txog cov kua thiab qhov quav;
3. Hom yeeb yaj kiab txawv, qhov kev sib txawv yog txawv;
4. Vim muaj ntau hom ntawm tus lej, muaj qhov sib txawv hauv kev ua txhaum;
5. Ib puag ncig cov huab cua txawv txawv, muaj qhov sib txawv hauv hluav taws xob;
6. Lub tshuab fais fab (av) tsis zoo li qub, yog li muaj qhov sib txawv;
7. Qhov txawv ntawm kev ua luam tawm ceev ceev.
Sib ntsib zoo:
1. Lub kaum sab xis ntawm lub siab rau cov tub ntxhais ntawm lub luam ntawv yog qhov obtuse kaum kom txo cov hluav taws xob stripping;
2. Tswj cov av noo, kom tsis txhob muaj 50% ntawm cov av noo, yuav tsum tau tswj kom siab tshaj 65% ntub kom txo cov hluav taws xob;
3. Saib xyuas lub xeev ntawm lub tshuab kom txhob txhuam nyiaj;
4. Txo cov ntawv luam tawm kom txo stripping, khiav kev txhuam thiab them nyiaj.
Feem ntau cov phenomena hauv electrostatic tsis ua hauj lwm yog "beard", "splashing" thiab "moire". Nws yog tsim nyog yuav tau them sai sai rau cov kev kho mob ntawm ntau yam tshwm sim.
1. Tsiaj txhu
Phenomenon: Cov ntawv cim dub, lub thawv ntawv, thiab thaj tsam ntawm cov ntawv luam tawm muaj ib daim npog uas zoo li lub thawv uas ya los ntawm cov kab mob qaum.
Countermeasure: Feem ntau yog ua kom zoo dua qub ntawm tus cwj mem xauv khov thiab txo qhov kev luam ntawv kom daws tau qhov teeb meem. Tam sim no hais tias qhov sib ntxiv ntawm tus neeg saib xyuas antistatic tsis txhim kho qhov kev sib tw, qhov txawv ntawm cov teebmeem ntawm cov ntawv luam tawm yuav pom tau tias.
2. Muab tus cwj mem los ntxuav
Phenomenon: Ob peb centimeters los ntawm tus qauv, fibrous number case flying tshwm sim.
Kev Tiv Thaiv: Txo cov xim ntawm tus cwj mem thiab siv cov kuab tshuaj ceev thiab qeeb kom ceev.
3. Moire
Phenomenon: Muaj ib lub voj voos loj los sis tsis pom ib qho ntawm qhov chaw hauv daim teb, tshwj xeeb tshaj yog thaum raug thaub nrog toluene.
Kev Tiv Thaiv: Qhov no muaj tsawg ua nrog cov viscosity thiab luam ntawv ceev ntawm tus number case. Nws yog qhov tshwj xeeb tshaj yog los mus ntxiv rau tus neeg saib xyuas antistatic thiab ib qho dej cawv me me.
Scraper, nws yuav hais tau tias ntau dua 70% ntawm cov kev ua yuam kev hauv kev luam tawm tau tshwm sim ntawm tus kws kho hniav thiab cov phaj ntawm cov phaj. Lub ntsiab tshwm sim ntawm cov hniav tsis ua hauj lwm yog:
1. Kab khib nyiab
Phenomenon: Tsis ntev cov kab ntev ntev tshwm hauv cov teeb meem luam tawm thiab cov khoom tsis muaj hlua.
Ua Ntej: Muaj cov kab ntawm cov khauj khaum thiab cov phaj ntawm cov phom, uas muaj kab mob txawv teb chaws, los yog cov hniav tsis zoo hauv av thiab puas. Nyuaj tuab: Muaj cov voj voos, ua rau cov hniav puas ntsoog: cov tuab tuab tuab: cov ntxaij mos muag, ob chav kab tshwm hauv qhov nruab nrab ntawm tus qauv.
Kev Tiv Thaiv: Cov cwj mem yuav tsum tau lim ua ntej thiab tom qab siv; qhov khawb ntawv yuav tsum yog av los yog hloov; lub twj tso kua npluas yuav tsum tau lim thaum siv.
2. Tshem plua plav
Phenomenon: Cov khoom seem, qhov kawg ntawm hom tawv dub, muaj kab kev lo lo ntxhuav.
Ua Ntej: Muaj ib qho txawv txav ntawm sab nraud ntawm sab hauv lub scraper. Vim tias qhov hloov ntawm qhov khawb ntawm qhov kawg, qhov txawv teb chaws teeb meem tawm sab nrauv thiab ib txoj kab qias neeg raug tsim tawm.
Kev Tiv Thaiv: tshem cov pav av thiab khij nyhos: muab cov kua mem tes los ntxuav thiab ntxuav sab hauv ntawm scraper; txo cov viscosity ntawm tus number case; thaum txhim kho qhov khawb ntawv, koj yuav tsum faj seeb kom ntev npaum li lub thawv kom tsis txhob khawb cov hnoos los yog muag heev.
3. Kev cim random
Phem Txoj Cai: Nyob rau hauv cov ntawv luam tawm thiab cov kab uas tsis yog ntim ntawm cov ntawv luam tawm, ib txoj kab qias neeg ntawm 1-2 cm yog cia li ua tiav.
Cause: Cov pob zeb me thiab cov mos mos muaj qias neeg tom qab ntws tawm ntawm qhov sib txawv nruab nrab ntawm khawb ntawv thiab lub phaj dov.
Kev Tiv Thaiv: pom ntawm tus cwj mem; rov tu tsev tshiab; qhov dav ntawm yob ua ntej luam ntawv yuav tsum pib dua.
Yog hais tias tsis muaj khoob khuab, qhov tshwm sim ntawm cov feem ntau yog qhov ntau tshaj. Nws tseem yog ib qho tseem ceeb rau lim tus cwj mem (150-200 mesh) kom tsis txhob muaj chaw nyob hauv chav tsev luam ntawv.
