Patent Professor - xibfwb Cui Yuefei
Cui Yuefei, tus tsim ntawm cov hnab dej-soluble hnab yas, ua tib zoo tshem tawm ob peb lub hnab yas ntawm hnab ris luv. Nws rub tawm lub hnab yas thiab ua kom pom nws cov dej-soluble. Txawm hais tias polyvinyl cawv, cov khoom siv nyob rau hauv kev tsim cov hnab yas, tsis muaj teeb meem rau lub cev, cov hnab yas tsis yog khoom noj thiab tsis raug txhawb.
Tshawb nrhiav thiab tsim kho "patent" tus xibfwb
Nws hais tias thaum nws yaim lub hnab yas nrog nws tus nplaig, thiab lub hnab yas yaj mus rau hauv nws lub qhov ncauj. Cui Yuefei tau yuav luag tag nrho ntawm cov hnab yas no ntau dua ib xyoo caum.
Cui Yuefei tuaj yeem hais tau nyob hauv cov khoom siv ntawm cov ntaub ntawv polymer rau lub neej. Xyoo 1985, tom qab kawm tiav ntawm "Science Science Department" ntawm South China University of Technology, nws nyob twj ywm mus kawm. Txawm li cas los xij, nws tig mus tshawb fawb plastics los ntawm lub caij nyoog. Thaum xyoo 1990, Cui Yuefei tau tsim nws pab pawg tshawb fawb, thiab tsuas yog xyoo ntawd, nws tau txais txoj haujlwm tshawb fawb los tsim cov tshav dav hlau ua kua nplaum hauv av. Cov cib fim no tso cai rau nws mus rau hauv lub qhov rooj ntawm hloov cov khoom siv yas.
Tsuas yog tom qab ntawd, nws pom txoj kev no nyuaj heev.
"Txij thaum ntawd los, tsis muaj sijhawm los sau ntawv thesis." Cui Yuefei tau hais tias feem ntau ntawm lub zog hluav taws xob tau siv rau kev tsim kho ntawm cov thev naus laus zis. Tam sim no, nws tau thov rau ntau dua 50 patents, uas yog "patent" tus xibfwb hauv lub tsev kawm ntawv. Hais txog kev tsim tawm ntawm lub hnab yas, muaj 36 daim patents uas tsim cov pas dej patent.
Cui Yuefei lub tswv yim yog qhov tseeb: "Daim ntawv sau txog cov niam txiv muaj peev xwm ze rau kev siv." Raws li 60 xyoo, Cui Yuefei tau hais tias: "Muaj ntau cov kev kawm ib txwm muaj txij thaum yau, thiab kuv tab tom xav txog qhov kev xav ntawm kuv tsev neeg. Txij li thaum kuv tau kawm qhov tseem ceeb no, kuv yuav tsum tau ua ib yam dab tsi ntawm tib neeg. Lub teb chaws, txawm tias tib neeg, yog qee yam. "
Tsis hais lub tebchaws rau penny
Thaum xyoo 1990, nws yog lub sijhawm ntawm Tuam Tshoj txoj kev txhim kho kev lag luam. Qhov kev thov rau cov ntaub ntawv yas kuj tau ua tiav thiab muaj ntau lub sijhawm. Cui Yuefei tau hais tias, "Peb lossis tsib txoj haujlwm yuav ua tiav nyob rau hauv ib xyoos." Tib lub sijhawm, txawm li cas los xij, Cui Yuefei paub txog qee qhov teeb meem muaj peev xwm. Los ntawm thaj tsam xyoo 2002, qee cov cuab yeej hluav taws xob loj tau muaj kaum tawm txhiab tus yas nyob hauv ib xyoos. "Lawv txhua tus saib rau peb tshawb nrhiav thiab saib cov plastics uas muaj tus nqi qis thiab tus nqi qis." Cui Yuefei tau hais tias, "Qhov tseeb nws nyuaj rau kev sib npaug ntawm ob thiab tsuas yog ntxiv qee cov khoom siv nyoos qis uas tsis yog ib puag ncig. . ”
Cui Yuefei pom tau hais tias qhov kev sib tw ntawm cov khoom siv ntawm cov lag luam tsis raug rau cov qauv kev sib raug zoo, thiab nws tseem yuav cia thev naus laus zis nkag mus rau "qhov kawg tuag". Nws tau paub meej: "Nws yog qhov ua tau los ua cov khoom siv rau cov khoom ib puag ncig." Txij thaum ntawd los, nws pab pawg thawj coj tau tig mus tshawb fawb thiab kev txhim kho cov khoom siv phooj ywg puag ncig.
Nrog cov kev taw qhia meej, Cui Yuefei pib tshawb fawb cov dej-cov tshuaj, uas yog cov khoom siv tseem ceeb ntawm lub hnab yas no. Txij li xyoo 2002, cov kev tshawb fawb hauv nruab nrab thiab kev txhim kho tau siv yim xyoo los ua tiav cov ntaub ntawv ntsuas pov thawj.
"Lub sijhawm tsis ntev, nws tsis yog luv luv," Cui Yuefei tau hais. Hauv lub sijhawm, muaj ntau yam lug kev, thiab "tuaj yeem" uas raug hla tawm yog lub tswv yim ntawm kev muab rau hauv feeb.
Thawj qhov uas tsis tuaj yeem daws yog qhov teeb meem ntawm kev tshawb nrhiav nyiaj. Cui Yuefei tau hais tias, "Tsis tas yuav tsum tau mus rau lub tebchaws rau ib lub penny", txhua tus uas tso siab rau kev tso nyiaj ua ntej dhau los ntawm cov nyiaj rau kev tshawb fawb khoom thiab kev txhim kho. Thaum pib, Kuv tseem nqa ib lug lug kev. "Nws siv peb xyoos, nyiaj txiag, thiab lub zog los ua pov thawj txoj hauv kev uas tsis tuaj yeem ua tiav."
500 cov khoom siv ua ntej thiab tom qab kuaj
"Tau kawg, tsis txhob ntaus phab ntsa thiab tsis paub yuav ua lwm txoj kev nrees." Cui Yuefei luag.
Thaum pib, nws tau poob rau hauv qhov kev xav ntawm cov txheej txheem yas ua qub. "PVA (Suav lub npe: dej cawv polyvinyl) yog cov khoom tseem ceeb ntawm peb lub hnab yas, nws cov khoom kis yog 220 ~ 230 ° C. Yog tias nws ua tiav raws li cov yas ib txwm, nws yuav tsum tau kho kom kub txog 220 ~ 230 ° C thiab tom qab ntawd ua tiav. "Cui Yuefei tsis cia siab tias" Thaum cov khoom no raug kho kom kub txog 180 ° C, nws pib ua kom zoo. ° C, nws yuav tsis tsuas yog decompose tab sis kuj ua rau muaj kev sib txuas loj heev. Vim li ntawd, tag nrho cov khoom daig thiab txav tsis tau txhua. "
"Koj yuav tsum hloov koj lub siab rov qab los!" Cui Yuefei tau hais tias, qhov no yuav tsum tau muaj lwm qhov kev daws teeb meem, thiab nws yuav raug tsim rau hauv cov yas-zoo li ntxiv mus txuas ntxiv. "Peb tuaj yeem ua kom tiav nws li cas los ntawm kev ua cua sov nws qis dua 180 ° C thiab tom qab ntawd ua nws?" Cui Yuefei tau hais tias qhov no yog qhov nyuaj tshaj plaws rau lub sijhawm ntawd. Yog li ntawd, lawv pom qee cov ntaub ntawv nyoos kom phim nrog PVA thiab tom qab ntawd lim los ntawm kev suav kev suav. Tom qab sim nrog ntau cov ntaub ntawv raw, lawv thaum kawg pom ntau tus khub "cov neeg koom tes".
Cov teeb meem tshiab tau tshwm sim: qee cov khoom sib txuam no yog tshuaj lom thiab tsis tau ua tiav ib puag ncig. Yog li ntawd, thawj thiab tiam thib ob ntawm cov dej-cov kua dej-hnab yas uas nws tsim tsis tau tshem tawm qhov no "nyuaj". Yuav kom daws tau qhov teeb meem no, peb tsuas tuaj yeem txuas ntxiv ua kev sim thiab nrhiav cov khoom. "Thaum kawg, maj mam nrhiav cov khoom siv tsis muaj tshuaj lom thiab tsis muaj mob kom hloov tag nrho cov khoom siv tshuaj lom." Cui Yuefei tau hais tias: "Ua ntej thiab tom qab, kwv yees li 500 yam ntawm cov khoom siv raw khoom tau raug kuaj." Txog xyoo 2008, hauv kev tshawb fawb thiab kev tsim khoom ntawm cov khoom siv, nws tau ua tiav zoo.
Cui Yuefei tsis xav tias nws yog thawj tus neeg "tau khiav mus txog thaum kawg" ntawm txoj haujlwm no. Vim tias, nyob hauv lub ntiaj teb, nrhiav kev lag luam yas ib puag ncig yog cov kev taw qhia txhua tus muaj qhov zoo txog. Thaum lub sijhawm ntawm Cui Yuefei qhov kev sim, tsis yog pab pawg tshawb fawb hauv tsev xwb, tabsis tseem muaj Ltalis, Nyijpooj thiab lwm lub tebchaws tabtom sim ua kom cov thev naus laus zis tawg.
Chile nyiam ua suav tshuab
Cui Yuefei tau ua qhov kev tshawb fawb thiab kev hloov pauv ntawm kev tshawb fawb txog kev ua tiav hauv ob peb lub xyoo dhau los, thiab nws muaj qee yam kev npaj rau lub siab xav txog "kev tsaws" hauv lub voj voog ntawm thev naus laus zis. Txawm li cas los xij, kev tos ntev ntev tseem tsis tau xav los ntawm Cui Yuefei.
Txog xyoo 2015, Cui Yuefei tau ntsib nrog Yang Zhenggao, tus thawj coj ntawm Jushi Chemical Co., Ltd. ntawm lub tsev kawm ntawv, thiab ob tog txiav txim siab sib koom tes.
"Ob tog tau pom zoo tias thawj zaug kev nqis peev nyob rau hauv qhov project tsim tawm, suav nrog thaj chaw, cov neeg ua haujlwm, cov khoom siv, cov khoom siv tshuaj, kev kuaj mob ntsig txog, daim ntawv pov thawj thiab lwm yam kev nkag siab yuav yog lub luag haujlwm ntawm lub tuam txhab. tseem ceeb patented yees thiab cov khoom nyoos tseem ceeb. "
Koob hmoov ib txwm nyiam lub siab npaj. Nyob rau lub Plaub Hlis 2016, thawj cov khoom sib tw ua cov khoom siv tsim tawm thiab thaum kawg ua tiav. Lub sijhawm no, nws tau tshwm sim los ntsib Roberto Astete ntawm Solubag, Chile. Lawv tau tshawb nrhiav cov khoom no hauv Suav teb tau ntau dua ob xyoos. Cui Yuefei tau hais tseg tias nws lub thev naus laus zis yog qhov hloov pauv ntawm txoj hmoo ntawm kev lag luam.
Nws qhia tias kev siv tshuab thev naus laus zis ntawm PVA raw khoom lag luam tsim tawm hauv Suav teb yog xa tawm ntawm Nyij Pooj mus rau Suav. Lub sijhawm ntawd, Tuam Tshoj tseem nyob rau lub sijhawm ntawm cov khoom siv tsis zoo. Cov khoom siv no tau siv los ua cov nylon, tsim rau hauv thom khwm thiab hws, thiab daws qhov teeb meem ntawm kev hnav khaub ncaws Suav. Cov. Tom qab ntawd, nrog txoj kev loj hlob ntawm cov tshuaj fiber ntau thev naus laus zis, txhua tus yuav tsis xav tau Wei nylon, uas ncaj qha coj mus rau overcapacity.
Txhua lub Vinylon factories tab tom nrhiav txoj hauv kev. "Lub sijhawm no, nws yog lub cib fim loj." Cui Yuefei tau hais ntxiv thiab zoo siab ntxiv: "Yog tias koj ua cov khoom lag luam rau cov khoom siv ib puag ncig, tsis ntev no koj yuav tuaj yeem txhim kho txoj saw kev lag luam."
Zoo heev rau kev daws teeb meem kev ua qias tuaj yas yas
Guangzhou Txhua Hnub: Xov xwm tshaj tawm hais tias “lub hnab ntim dej-soluble uas tuaj yeem noj thiab haus” tau tiag tiag noj thiab haus?
Cui Yuefei: Ntau cov tshaj tawm tau tshaj tawm cov lus tshaj tawm cov dej polyvinyl cawv dej-soluble cov ntaub ntawv, thiab txawm piav qhia polyvinyl cawv dej-soluble hnab ua tau thiab haus tau. Nov yog cov lus piav tsis muaj tseeb thiab tsis muaj tseeb. Ntawm no, peb tsuas yog lav tias polyvinyl cawv cov ntaub ntawv thiab cov khoom tsim los ntawm kev siv peb lub thev naus laus zis thiab cov khoom siv raw yog tsis muaj tshuaj lom thiab tsis muaj teeb meem, tab sis tsis tuaj yeem lav tias lwm cov ntaub ntawv cawv polyvinyl thiab cov khoom lag luam hauv khw kuj tsis muaj tshuaj lom thiab tsis muaj mob.
