Lub SUNNYJOINT roj hmab ntxiv cov cwj pwm ntawm cov log tsheb ntsuab tsis yog siv los ntawm cov xim ntsuab thiab kev ruaj ntseg thaum kawg, xws li qis tsis kam, tsis tshua muaj suab nrov, ntub ua haujlwm, kev tuav pov hwm siab, thiab lwm yam, kev siv ntsuab cov ntaub ntawv, kev tshawb nrhiav ntsuab thiab kev loj hlob. Kev xav, cov txheej txheem ntsuab, kev txuag thiab kev txuag dua. Ntawm lawv, lub greening ntawm roj hmab additives muaj yuav tsum tau hais.
Cov xov xwm tau kawm tias kev siv qee cov roj hmab cov khoom uas tsim kev puas tsuaj rau tib neeg lub cev thiab qhov chaw nyob thaum lub sijhawm tsim cov khoom qis yuav tsis tsim teebmeem. Tib lub sij hawm, teeb meem ntxiv yuav raug kuab nyob rau hauv lub cheeb tsam li lub log tsheb siv thiab hnav. Kev tsim khoom ntawm cov log tsheb ntsuab yuav tsum siv cov non-polluting auxiliaries thiab tswj los ntawm qhov chaw kom tau raws li cov cai ntawm cov log tsheb ntsuab. Los ntawm ze li ntawm 10 xyoo ntawm kev ua haujlwm, Tuam Tshoj cov khoom siv roj hmab muaj peev xwm ua tiav ib puag ncig kev tiv thaiv thiab kev hloov pauv hloov ntsuab, thiab qhov ntsuas ntau tau tshaj tawm txog qee thoob ntiaj teb tag nrho.
Nws to taub hais tias kev lag luam rubber siv tag nrho ntawm 6 yam ntawm cov khoom siv ntxiv: cov khoom siv los ntawm vulcanization additives, tseem hu ua accelerators; kev tiv thaiv system ntxiv, los yog cov neeg ua hauj lwm tiv thaiv kev laus; operating system additives, xws li cov yas yas, cov khoom softeners, etc .; Muaj zog filling system ntxiv, xws li carbon dub thiab silica, etc .; adhesion system additives, xws li triazine binders; lwm yam khoom siv xws li xim liab. Nyob rau xyoo 2014, tag nrho cov khoom loj ntawm 6 lub koom haum nyob rau hauv Suav teb yog kwv yees li 5,8 lab tons, uas cov xim dub thiab dawb carbon dub reinforcing fillers accounted rau 80%, thiab accelerators thiab antioxidants account txog li 16% ntawm tag nrho. Qhov no yog qhov tso zis thiab Feem ntau peb siv cov roj hmab ntxiv.
Nyob rau xyoo 1990, tom qab Michelin tau pib ua kom cov menyuam kawm tiav high-performance tha xim nrog cov xim dub, cov log tsheb ntsuab yau tau txais los ntawm cov pejxeem rau kev nplij siab, kev nyab xeeb, kev tiv thaiv thiab kev txuag lub zog.
Xyoo tas los no, lub ntiaj teb no siv cov cav ntsuab siv cov roj dawb tau tuav tseg txhua xyoo kev loj hlob ntawm 10% mus rau 20%, thiab ntau thiab ntau qhov qub log qhia tau pib qhia ntxiv cov roj dawb. Raws li Tuam Tshoj txoj cai rau kev tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab kev nplij siab tau txais ntau dua thiab ntau dua, feem ntau ntawm cov dawb cov dub dub hauv log kuj nce mus.
Tam sim no, cov dawb dub cov khoom pov thawj ua tau zoo hauv kev txo txoj kev ua hauj lwm thiab kev txhim kho kev ua tau zoo, thiab yog li tau siv dav hauv cov log tsheb, cov nplhaib tsis khiab, thiab cov log tsheb ntsuab. Cov ntaub ntawv qhia tau hais tias tus nqi ntawm cov tsheb dawb ntxiv rau domestic lub rooj sib tsoo hauv xyoo 2012 tsuas yog 180,000 tons, thiab los ntawm qhov kawg ntawm lub xyoo no, kev siv cov log tsheb domestic yuav tsum ncav cuag 600,000 tons.
Cov kev kho tshiab hauv kev tsuj roj thiab cov antioxidants tau nce mus sai heev. Kaum lub xyoo dhau los, NOBS (N-oxydiethyl-2-benzothiazole sulfenamide) yog qhov tseem ceeb tshaj plaws ntawm txoj hlua, uas pom tias muaj teeb meem rau tib neeg hauv cov teb chaws. Tom qab ze li ntawm kaum xyoo ntawm txoj kev loj hlob, tus ntsuab ntsuab nce qib raws li tus txhawb nqa NS (N-tert-butyl-2-benzothiazole sulfenamide) tau hloov lub pob TSIS NO.
Zhang Fang, tus pab cuam rau tus thawj coj ntawm lub Petroleum thiab Tshuaj Kev Lag Luam Npaj Lub Tsev Kawm Ntawv, taw tes tias kev loj hlob yav tom ntej ntawm cov khoom siv roj hmab ntau tshaj yog feem ntau thaws rov los hauv peb yam.
Ua ntej, yuav kom ua tau raws li qhov kev xav tau ntawm cov log tsheb ntsuab, optimize cov khoom qauv ntawm cov khoom siv tub rog. Siv cov xim dub es siv cov paib dub tuaj yeem txo qhov rub tawm ntawm lub log. Nyob rau hauv lub neej yav tom ntej, feem ntau ntawm cov dawb cov roj dub nyob rau hauv reinforcing fillers yuav nce, thiab cov khoom siv ntawm silane coupling cov neeg ua hauj lwm yuav tsim muaj sai.
Qhov thib ob yog los txhawb txoj kev tsim cov dej huv ntawm cov khoom siv roj hmab ntxiv. Cov khoom siv roj hmab loj tshaj plaws yog cov accelerators thiab cov neeg ua hauj lwm tiv thaiv kev laus, thaum lub koom haum loj tshaj plaws los tiv thaiv kev laus laus yog 4020. Nws to taub tias cov txheej txheem 4020 kev tsim tawm "peb chaw" yog qhov loj, -Cov ntaub ntawv tsim los ntawm nitrobenzene, RT (N-phenyl p-phenylenediamine)) los tsim cov txheej txheem ntawm antioxidant 4020. Nyob rau xyoo tas los no, ntau yam kev ua los ntawm cov laus cov neeg ua haujlwm 4020 uas tau ua los ntawm cov txheej txheem no raug muab tso rau hauv , thiab cov txheej txheem cov kev cai xws li kev hloov cov formylanilide txoj kev yuav tsum ceev nrawm rau yav tom ntej.
Qhov thib peb yog los txhawb kev tiv thaiv ib puag ncig ntawm cov khoom siv roj hmab ntxiv. Lub hom phiaj tsis ntev los no yog nyob rau ntawm thaj chaw zoo rau kev khiav dej num rau kev khiav hauj lwm, xws li hloov cov roj ntau cov roj ntsha nrog cov roj naphthenic cov roj, siv DBD (2.2-dibenzamide diphenyl disulfide). Plasticizer B (pentachlorothiophenol).
Nrog txoj kev loj hlob ntawm lub tswv yim ntawm cov log tsheb ntsuab, qee lub tuam txhab kev lag luam thiab cov chaw tshawb fawb tau pib kawm cov kev tshawb fawb ntsuab log. Ntxiv rau cov additives, tag nrho kev lag luam saw ntawm domestic log tsim, cov ntaub ntawv, khoom siv, machinery, thiab lwm yam. Kuj tseem tab tom xyaum tib lub sij hawm, thiab tag nrho cov me nyuam yaus yog tab tom ua haujlwm tom qab. Cov no tau tso tau lub hauv paus zoo rau txoj kev loj hlob ntawm Tuam Tshoj cov log tsheb ntsuab, thiab Tuam Tshoj yuav nyob ze rau kev ua tau lub hom phiaj ntawm txoj kev lag luam thoob ntiaj teb.
