Cov khoom siv roj hmab muaj nyob txhua qhov chaw hauv peb lub neej, tsis hais nws yog tsheb, tshuab, khoom siv hluav taws xob lossis khoom siv niaj hnub, cov khoom siv roj hmab tsis sib cais. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev siv, cov khoom siv roj hmab tuaj yeem muaj cov kab nrib pleb, uas tsis tsuas yog cuam tshuam rau cov tsos, tab sis kuj tuaj yeem ua rau kev poob qis hauv kev ua haujlwm thiab txawm tias poob ntawm kev siv tus nqi. Yog li, dab tsi yog qhov ua rau tawg ntawm cov khoom siv roj hmab?
Ua ntej, lub ntsiab ua rau cov khoom siv roj hmab tawg
1. Khoom yog vim li cas
Qhov teeb meem tawg ntawm cov khoom siv roj hmab feem ntau muaj feem xyuam rau qhov zoo thiab cov khoom ntawm cov khoom. Yog tias qhov zoo ntawm cov khoom siv roj hmab tsis yog raws li tus qauv, xws li cov ntsiab lus sulfur, cov ntsiab lus nitrogen, cov hmoov tshauv thiab lwm cov khoom ntawm cov roj hmab vulcanized tsis tsim nyog, nws yuav ua rau tawg ntawm cov khoom thaum siv. Tsis tas li ntawd, yog tias qhov zoo ntawm cov khoom siv xws li cov ntaub ntawv sau thiab cov khoom siv ntxiv rau cov khoom siv roj hmab tsis yog raws li tus qauv, nws tseem yuav ua rau lub zog tsis txaus ntawm cov khoom, thiab tom qab ntawd tawg.
2. Pwm yog vim li cas
Cov pwm yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv roj hmab. Yog tias tus qauv tsim pwm tsis tsim nyog lossis qhov kev tsim khoom zoo tsis yog raws li tus qauv, nws yuav ua rau muaj kev ntxhov siab ntawm cov khoom siv roj hmab thaum lub sij hawm molding txheej txheem, uas yuav ua rau tawg ntawm cov khoom thaum siv. Tsis tas li ntawd, pwm hnav thiab kev puas tsuaj kuj tuaj yeem ua rau tawg ntawm cov khoom siv roj hmab.
3. Cov txheej txheem ntau lawm yog vim li cas
Cov txheej txheem ntawm cov khoom siv roj hmab muaj kev cuam tshuam zoo rau cov khoom siv roj hmab zoo. Yog tias vulcanization kub, vulcanization lub sij hawm, siab thiab lwm yam txheej txheem tsis tswj kom zoo, nws yuav ua rau tsis txaus lub zog ntawm cov khoom siv roj hmab, hardness tsis yog nruab nrab, thiab ces ua rau tawg. Tsis tas li ntawd, yog tias kev ua haujlwm tsis zoo hauv cov txheej txheem tsim khoom, xws li kev ncab ntau dhau, ntau folding, thiab lwm yam, kuj yuav ua rau tawg ntawm cov khoom siv roj hmab.
4. Siv ib puag ncig vim li cas
Kev siv ib puag ncig ntawm cov khoom siv roj hmab muaj kev cuam tshuam zoo rau nws lub neej thiab kev ua haujlwm. Yog tias kev siv ib puag ncig hnyav heev, xws li kub, tsis kub, roj, acid thiab alkali thiab lwm yam corrosive ib puag ncig, tuaj yeem ua rau cov khoom siv roj hmab ua kom muaj kev laus, ua rau tawg.
Thib ob, cov khoom siv roj hmab tawg cov lus teb ntsuas
1. Xaiv cov khoom siv zoo
Txhawm rau tsim cov khoom siv roj hmab zoo, cov khoom siv raw khoom zoo yuav tsum tau xaiv. Hauv kev yuav khoom ntawm cov khoom siv roj hmab, peb yuav tsum tau them sai sai rau nws cov ntsiab lus sulfur, cov ntsiab lus nitrogen, cov hmoov tshauv thiab lwm cov ntsiab lus tseem ceeb los xyuas kom meej cov khoom zoo. Nyob rau tib lub sijhawm, cov ntaub ntawv pabcuam xws li cov ntaub ntawv sau thiab cov ntaub ntawv txhawb nqa yuav tsum tau soj ntsuam nruj me ntsis.
2. Txhim kho pwm tsim
Cov pwm yog tus yuam sij rau kev tsim cov khoom siv roj hmab. Cov pwm tsim yuav tsum tau ua kom zoo kom tsis txhob muaj cov kab ntse ntse thiab cov npoo ntawm cov pwm uas ua rau muaj kev ntxhov siab thiab txo qhov kev pheej hmoo ntawm kev tawg thaum lub sij hawm molding txheej txheem. Nyob rau tib lub sijhawm, xyuam xim rau kev tshuaj xyuas thiab kev saib xyuas ntawm cov pwm kom ntseeg tau tias qhov raug thiab zoo ntawm pwm.
3. nruj me ntsis tswj cov txheej txheem ntau lawm
Hauv kev tsim cov khoom siv roj hmab, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj lub vulcanization kub, vulcanization lub sij hawm, siab thiab lwm yam txheej txheem tsis los xyuas kom meej tias cov khoom muaj txaus lub zog thiab hardness. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los ntxiv dag zog rau kev ua haujlwm tshwj xeeb hauv cov txheej txheem tsim khoom kom tsis txhob muaj kev sib tw, dhau-folding thiab lwm yam haujlwm uas yuav ua rau tawg.
4. Txhim kho qhov kev laus ntawm cov khoom siv roj hmab
Raws li kev cuam tshuam ntawm kev siv ib puag ncig ntawm cov khoom siv roj hmab, cov tshuaj tiv thaiv kev laus, cov tshuaj tua kab mob antioxidant, cov tshuaj tiv thaiv ultraviolet thiab lwm yam tshuaj ntxiv tuaj yeem ntxiv los txhim kho kev laus ntawm cov khoom siv roj hmab thiab txuas ntxiv lawv lub neej kev pab.
Hauv luv luv, muaj ntau qhov laj thawj rau kev tawg ntawm cov khoom siv roj hmab, thiab txhawm rau daws qhov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam thiab txhim kho los ntawm ntau yam xws li cov khoom siv raw, pwm, cov txheej txheem ntau lawm thiab kev siv ib puag ncig. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem txo qhov kev pheej hmoo ntawm cov kab nrib pleb hauv cov khoom siv roj hmab thiab ua kom cov khoom zoo thiab kev pabcuam lub neej.
