tsim
Roj hmab cov menyuam molding yog tsuas yog muab tshuaj txhuam cov roj hmab rau ntawm cov tub ntxhais hlau, nrog rau txoj kev qhwv, txoj kev extrusion, txoj kev molding, txoj kev txhaj tshuaj siab thiab txoj kev txhaj tshuaj.Tam sim no, cov khoom tseem ceeb hauv tsev yog kev siv tshuab lossis phau ntawv pasting thiab molding, thiab ntau lub teb chaws txawv teb chaws tau paub txog txhua yam automation.Cov roj hmab loj thiab nruab nrab ntawm cov menyuam yaus yog tsim los ntawm profiling extrusion, nruam pasting molding los ntawm extruded zaj duab xis los yog nruam winding molding los ntawm extruding daim kab xev.Nyob rau tib lub sijhawm, nyob rau hauv cov txheej txheem molding, cov kev qhia tshwj xeeb, qhov ntev thiab cov duab zoo li tau tswj hwm los ntawm microcomputer, thiab qee qhov kuj tuaj yeem ua pwm los ntawm txoj cai-lub kaum sab xis extruder thiab tshwj xeeb-zoo li tus extrusion.
Cov txheej txheem molding tau hais los saum toj no tuaj yeem tsis tsuas yog txo kev siv zog, tab sis kuj tshem tawm cov npuas ua tau.Txhawm rau tiv thaiv cov menyuam roj hmab los ntawm kev deforming thaum lub sij hawm vulcanization thiab tiv thaiv kev tsim cov npuas thiab daim txhuam cev, tshwj xeeb tshaj yog rau cov menyuam roj hmab molded los ntawm txoj kev qhwv, yuav tsum siv txoj kev hloov pauv mus rau sab nraud.Feem ntau, sab nrauv ntawm cov menyuam roj hmab yog qhwv thiab lub qhov txhab nrog ob peb txheej ntawm cov ntaub paj rwb lossis ntaub nylon, thiab tom qab ntawd tsau thiab nias nrog steel hlau lossis fiber ntau hlua.Txawm hais tias cov txheej txheem no twb tau hloov kho lawm, kev hnav khaub ncaws yuav tsum tau muab tshem tawm tom qab vulcanization los tsim cov txheej txheem "cecal", uas nyuaj rau kev tsim khoom.Tsis tas li ntawd, kev siv cov ntaub hnav khaub ncaws thiab cov hlua winding tsis tshua muaj kev txwv thiab kev siv ntau heev.pov tseg.
Rau me me thiab micro roj hmab rollers, ntau yam txheej txheem yuav siv tau, xws li phau ntawv patching, extrusion zes, txhaj tshuaj, txhaj tshuaj thiab pouring.Txhawm rau txhim kho kev tsim khoom, feem ntau ntawm cov txheej txheem molding yog tam sim no siv, thiab qhov tseeb yog ntau dua li ntawm txoj kev uas tsis yog molding.Kev txhaj tshuaj siab, kev txhaj tshuaj ntawm cov roj hmab thiab cov kua roj hmab tau dhau los ua cov txheej txheem tseem ceeb tshaj plaws.
Vulcanization
Tam sim no, vulcanization txoj kev loj thiab nruab nrab ntawm cov roj hmab rollers tseem yog vulcanization tank vulcanization.Txawm hais tias qhov hloov pauv hloov pauv tau hloov pauv, nws tseem tsis tau tawg tawm ntawm kev ua haujlwm hnyav ntawm kev thauj mus los, nqa thiab tshem tawm.Lub vulcanization cua sov qhov chaw muaj peb txoj kev cua sov: chav, cua kub thiab dej kub, thiab lub ntsiab tseem yog chav.Cov roj hmab chais nrog cov kev cai tshwj xeeb vim yog kev sib cuag ntawm cov tub ntxhais hlau nrog cov dej vapor txais kev ncaj qha chav vulcanization, thiab lub sijhawm yuav ntev li 1 txog 2 zaug.Nws feem ntau yog siv rau cov menyuam roj hmab nrog hollow hlau cores.Rau cov menyuam roj hmab tshwj xeeb uas tsis tuaj yeem vulcanized nrog lub tank vulcanizing, cov dej kub yog qee zaum siv rau vulcanization, tab sis kev kho cov dej paug yuav tsum tau daws.
Txhawm rau tiv thaiv cov roj hmab thiab cov tub ntxhais hlau los ntawm kev delaminated vim qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov roj hmab cov menyuam thiab cov tub ntxhais roj hmab, cov vulcanization feem ntau siv cov cua sov qeeb thiab siab nce txoj kev, thiab lub sij hawm vulcanization yog ntau. ntev tshaj li lub sij hawm vulcanization xav tau los ntawm cov roj hmab nws tus kheej..Txhawm rau kom ua tiav cov vulcanization hauv thiab sab nraud, thiab ua kom cov thermal conductivity ntawm cov tub ntxhais hlau thiab cov roj hmab zoo sib xws, cov roj hmab loj nyob hauv lub tank rau 24 txog 48 teev, uas yog li 30 txog 50 npaug ntawm lub sijhawm roj hmab vulcanization. .
Me thiab micro roj hmab rollers yog tam sim no feem ntau hloov dua siab tshiab rau phaj vulcanizing xovxwm molding vulcanization, hloov tag nrho cov tsoos vulcanization txoj kev ntawm roj hmab rollers.Nyob rau hauv xyoo tas los no, cov tshuab txhaj tshuaj molding tau siv los txhim kho cov pwm thiab lub tshuab nqus tsev vulcanization, thiab pwm tuaj yeem qhib thiab kaw tau.Lub degree ntawm kev siv tshuab thiab automation tau zoo heev, thiab lub sij hawm vulcanization yog luv, cov efficiency ntau lawm, thiab cov khoom zoo.Tshwj xeeb tshaj yog thaum siv cov roj hmab txhaj tshuaj molding vulcanizing tshuab, ob txheej txheem ntawm molding thiab vulcanization yog ua ke rau hauv ib qho, thiab lub sij hawm yuav luv luv rau 2 mus rau 4 feeb, uas tau dhau los ua ib qho tseem ceeb ntawm kev tsim cov roj hmab cov menyuam cov khoom.
Tam sim no, cov roj hmab ua kua uas sawv cev los ntawm polyurethane elastomer (PUR) tau tsim sai hauv kev tsim cov roj hmab chais, thiab tau qhib txoj kev tshiab ntawm cov khoom siv thiab cov txheej txheem hloov pauv rau nws.Nws txais yuav daim ntawv pouring kom tshem tawm ntawm txoj haujlwm molding thiab cov khoom siv vulcanization loj heev, ua kom yooj yim rau cov txheej txheem ntawm cov roj hmab chais.Txawm li cas los xij, qhov teeb meem loj tshaj plaws yog cov pwm yuav tsum tau siv.Rau cov menyuam roj hmab loj, tshwj xeeb tshaj yog rau cov khoom lag luam ib leeg, cov nqi tsim khoom tau nce siab heev, uas ua rau muaj teeb meem loj rau kev nce qib thiab siv.
Txhawm rau daws qhov teeb meem no, cov txheej txheem tshiab ntawm PUR roj hmab cov menyuam tsis muaj pwm tsim tau tshwm sim nyob rau xyoo tas los no.Nws siv polyoxypropylene ether polyol (TDIOL), polytetrahydrofuran ether polyol (PIMG) thiab diphenylmethane diisocyanate (MDl) ua raw khoom.Nws reacts sai sai tom qab sib tov thiab nplawm, thiab yog quantitatively poured mus rau maj mam rotating roj hmab cov menyuam hlau core., Nws yog ib kauj ruam los ntawm kauj ruam thaum pouring thiab kho, thiab thaum kawg cov roj hmab cov menyuam yog tsim.Cov txheej txheem no tsis tsuas yog luv luv hauv cov txheej txheem, siab hauv tshuab thiab automation, tab sis kuj tshem tawm qhov xav tau ntawm cov pwm loj.Nws tuaj yeem tsim cov menyuam roj hmab ntawm ntau qhov tshwj xeeb thiab qhov ntau thiab tsawg ntawm qhov xav tau, uas txo tus nqi zoo heev.Nws tau dhau los ua txoj kev loj hlob tseem ceeb ntawm PUR roj hmab rollers.
Tsis tas li ntawd, micro-fine roj hmab rollers siv nyob rau hauv kev tsim cov khoom siv hauv chaw ua haujlwm automation nrog cov kua silicone roj hmab kuj tseem txhim kho sai thoob plaws ntiaj teb.Lawv muab faib ua ob pawg: kev kho cua sov (LTV) thiab chav kub kho (RTV).Cov cuab yeej siv kuj tseem txawv ntawm PUR saum toj no, tsim lwm hom casting daim ntawv.Ntawm no, qhov teeb meem tseem ceeb tshaj plaws yog yuav ua li cas tswj thiab txo cov viscosity ntawm cov roj hmab sib xyaw kom nws tuaj yeem tswj tau qee qhov siab thiab extrusion ceev.
