Choyamba, ntchito yamakampani a cellulose ether
Ndi chitukuko chofulumira cha zomangamanga, chakudya, mankhwala, mankhwala a tsiku ndi tsiku ndi mafakitale ena, kufunikira kwa msika wapadziko lonse wa zinthu zopanda ionic cellulose ether zakwera kwambiri m'zaka zaposachedwa.Pambuyo 2000, mapadi etero makampani mofulumira chitukuko m'dziko lathu, mankhwala ndi wolemera, ndi kukwaniritsa ntchito lonse mosalekeza pa masitepe, mtanda wa matani chikwi mu aliyense bizinesi kupambana, mankhwala kuchokera otsika kukhuthala mkulu, mamasukidwe akayendedwe ku chinthu chimodzi. ku kagawidwe ka mankhwala pang'onopang'ono kulowa ntchito msika, kwambiri kusintha khalidwe mankhwala, m'ma osiyanasiyana mankhwala pang'onopang'ono mlingo wa mayiko, Kuchokera kunja dziko kupita kunja.Pakali pano, mabizinesi zoweta mapadi etere kupanga pafupifupi 70, makamaka kufalitsidwa mu Shandong, Jiangsu, Henan, Hebei ndi Chongqing ndi malo ena.Malinga ndi zomwe zatulutsidwa ndi China Cellulose Viwanda Association, kuchuluka kwa cellulose ether ku China mu 2017 kunali matani 373,300, kukwera ndi 17,3% chaka ndi chaka.Amene makamaka ntchito zomangira, mankhwala ndi chakudya HPMC akuimiridwa ndi sanali ionic mapadi etere mapadi chitukuko mfundo zazikulu ndi mphamvu yatsopano yoyendetsa, 2017 linanena bungwe pafupifupi 180,000 matani, mlandu pafupifupi 48% ya okwana linanena bungwe la m'banja mapadi efa.
Cellulose ether ndiye chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope.Kuchuluka kwa cellulose ether ndi otsika kwambiri, koma kumatha kusintha kwambiri magwiridwe antchito azinthu zamatope.Ndi gawo lofunikira la matope owuma owuma komanso matope apadera owuma.HPMC mu matope owuma osakanikirana monga oimira a non-ionic cellulose ether, amagwiritsidwa ntchito kwambiri posindikiza, kupaka pamwamba, kuyika matailosi a ceramic ndikuwonjezera mumatope a simenti.Makamaka mumatope a simenti osakaniza ndi pang'ono HPMC akhoza kuonjezera mamasukidwe akayendedwe, kasungidwe madzi, pang'onopang'ono coagulation ndi mpweya kulowetsedwa kwenikweni, kwambiri kusintha ceramic matailosi binder, putty ndi zinthu zina chomangira ntchito, kukana chisanu ndi kutentha kukana, kumakoka ndi kukameta ubweya mphamvu, kuti apititse patsogolo ntchito yomanga ya zida zomangira, kupititsa patsogolo luso la zomangamanga komanso luso la zomangamanga.
M'zaka zaposachedwa, ndi chidwi chowonjezeka cha boma pachitetezo cham'matauni, National Development and Reform Commission, Unduna wa Zamalonda, Unduna wa Zanyumba ndi Kutukuka kwa Mizinda-Kumidzi ndi madipatimenti ena ofunikira adalengeza ndikukhazikitsa malamulo angapo okhudza chitetezo cham'matauni. kugwiritsa ntchito matope osakaniza owuma.Pakadali pano, mizinda yopitilira 300 ku China yakhazikitsa mfundo zoyenera zogwiritsira ntchito matope owuma owuma.Kukwezeleza mwachangu kwamatope osakaniza owuma kwachititsa kukula kwa msika wa HPMC.Mu dongosolo la 13 la zaka zisanu, kulimbikitsa kugwiritsa ntchito zipangizo zomangira zatsopano (kuphatikiza zipangizo zatsopano zapakhoma, zipangizo zotetezera kutentha, zipangizo zomangira madzi, zopangira zokongoletsera zomangira ndi magulu ena anayi a zipangizo zofunika) ndiye chitsogozo cha chitukuko chomwe chimalimbikitsidwa ndi makampani dziko, tsogolo LA HPMC mankhwala adzakhala ndi malo ambiri chitukuko.
Mu okwana kuchuluka kwa zomangira kalasi mapadi efa, zomangira kalasi mapadi efa mu 2017 mlingo wa matani 123,000 kapena kotero, mapadi etero angapo ntchito zazikulu za ceramic matailosi binder, khoma kutchinjiriza dongosolo kuthandiza matope, putty, wamba youma osakaniza matope, gypsum zochokera mankhwala, sealant, matope kukongoletsa, ALC zomangamanga matope ndi pulasitala matope, mawonekedwe wothandizira.Pakati pa mapulogalamu omwe ali pamwambawa, mafakitale otsekemera ndi mafakitale opangidwa ndi matope okonzeka amadalira kwambiri zomangamanga zatsopano, pamene ntchito zina zakhala zikukhudzidwa kwambiri ndi kukonzanso ndi kukonzanso nyumba zomwe zilipo kale, zomwe tinganene kuti zili mu njira ya kukula.Malinga ndi kuyerekezera uku, kuchuluka kwa msika kudzakwera mu 2018.
Makampani akunja a cellulose ether adayamba kale, ndi Dow Chemical, Yiletai, Ashlan gulu ngati woyimira mabizinesi opanga kupanga ndi njira yomwe ili patsogolo kwambiri.Limited ndi luso, mabizinezi zoweta mapadi etere makamaka kubala otsika mtengo-anawonjezera mankhwala ndi njira yosavuta ndondomeko ndi otsika mankhwala chiyero, ndi luso lapamwamba ndi mankhwala mkulu mtengo-anawonjezera alibe kutchuka mu China.Zomangamanga kalasi mapadi etere ntchito yomanga mkombero ndi lalifupi, mankhwala chimagwiritsidwa ntchito, kotero pali chodabwitsa cha kukula molongosoka kwa makampani, mpikisano molongosoka mu msika kumabweretsa mphamvu owonjezera, konse wathunthu ziwerengero deta, mphamvu panopa wa mapadi etere ku China ndi pafupifupi matani 250,000, ambiri a iwo otsika-mapeto zomangira kalasi mankhwala.
Ndi kusintha kwa zofunika boma chitetezo chilengedwe, 2015 mayiko anakhazikitsa okhwima madzi oipa, zinyalala mpweya zofunika mpweya, ndi kuba, osati kupanga mankhwala amadzi onyansa, ndi kosakhazikika mankhwala ndi mankhwala ndi mchere malonda pang'onopang'ono malamulo, osati luso kusintha mabizinesi pang'onopang'ono kuthetsedwa, mu hebei, shandong ndi malo ena, mabizinesi ena ang'onoang'ono a cellulose ether atsekedwa, Mpikisano wosalongosoka wamakampani a cellulose ether udzawongoleredwa.
Awiri, mapadi ether makampani chitukuko cha zinthu zazikulu
(a) zinthu zopindulitsa zomwe zimakhudza chitukuko cha makampani a cellulose ether
1. Ntchito zothandizira mfundo za dziko ndi kukwezeleza anthu zakulitsidwa
China Unduna wa Zamakampani ndi Information Technology inapereka zomangamanga makampani "khumi ndi ziwiri Zaka zisanu" dongosolo chitukuko "ananena kuti zomangira kalasi mapadi etero monga mkulu-ntchito zowonjezera, akhoza kusintha kasungidwe madzi a zomangira, mamasukidwe akayendedwe, kupulumutsa mphamvu, kuteteza zachilengedwe, mogwirizana ndi ndondomeko ya dziko la mafakitale."Zida zomangira zatsopano" zakhumi ndi ziwiri "ndondomeko yachitukuko" yazaka zisanu idawonetsa kuti chitetezo, kuteteza chilengedwe, kupulumutsa mphamvu zomangira zatsopano (kuphatikiza zida zatsopano zapakhoma, zida zotenthetsera zotentha, zomangira zopanda madzi, zida zokongoletsera zomangira ndi magulu ena anayi azinthu zofunikira. ) ndi “zaka khumi ndi zisanu ndi ziwiri” pakupanga zinthu zatsopano zomangira.Kuwonjezera mapadi efa akhoza kusintha ndi kukhathamiritsa ntchito zipangizo zatsopano khoma, zipangizo zokongoletsera nyumba ndi zipangizo zina zomangira, kuphatikizapo gypsum bolodi, matenthedwe kutchinjiriza matope, youma kusakaniza matope, PVC utomoni, lalabala utoto, etc., mogwirizana ndi zofunika mphamvu kupulumutsa ndi kuteteza chilengedwe.Boma limalimbikitsa kupanga zida zatsopano zomangira, zomwe zimathandizira kukulitsa kufunikira kwa HPMC pamsika wapakhomo.
2, chuma cha dziko kulimbikitsa chitukuko cha makampani
Pazaka 30 zapitazi, chuma cha dziko la China chakhalabe ndi chitukuko chokhazikika komanso chofulumira, mlingo wonse wa makampani oyenerera ndi moyo wa anthu zakhalanso bwino kwambiri, ether cellulose imadziwika kuti "industrial MONOsodium glutamate", imagwiritsidwa ntchito kwambiri madera osiyanasiyana a chuma cha dziko, chitukuko cha zachuma zidzayendetsa kukula kwa mafakitale a cellulose ether.Ndi kupititsa patsogolo thanzi la anthu komanso kuzindikira kwa chilengedwe, HPMC yotereyi yopanda ionic cellulose ether idzalowa m'malo mwa zida zina, ndikugwiritsidwa ntchito kwambiri ndikupangidwa.
3. Kuchulukitsa kufunikira kwa msika ndi chiyembekezo cholonjeza chitukuko
Malinga ndi unduna wa zanyumba ndi chitukuko cha m’matauni-kumidzi, mphamvu zogwiritsa ntchito m’nyumba zimagwiritsa ntchito 28 peresenti ya mphamvu zonse zomwe dziko la China limagwiritsa ntchito.Mwa pafupifupi 40 biliyoni masikweya mita a nyumba zomwe zilipo kale, 99% ndizogwiritsa ntchito mphamvu zambiri, zomwe zimagwiritsidwa ntchito potentha pagawo lililonse lofanana ndi 2-3 nthawi yamayiko otukuka omwe ali ndi latitude yofanana.Mu 2012, Ministry of Housing and Urban-Rural Development anaika patsogolo "Khumi ndi Zisanu Zaka zisanu" Building Energy Conservation Plan Special, amene ananena kuti ndi 2015, cholinga cha 800 miliyoni lalikulu mamita wa nyumba zatsopano zobiriwira;Pakutha kwa nthawi yokonzekera, nyumba zopitilira 20% zanyumba zatsopano zamatauni zidzakwaniritsa miyezo yomanga yobiriwira, kutulutsa kwa zida zatsopano zamakhoma kudzapitilira 65% ya zida zonse zapakhoma, ndipo gawo lazomangamanga lidzafika. kuposa 75%.HPMC ngati chowonjezera chomangira chatsopano, chidzalowa m'malo mwa etha yapa cellulose yachikhalidwe idzagwiritsidwa ntchito pazinthu zatsopano zomangira, chiyembekezo chamsika ndi chotakata.
(B) zinthu zoyipa zomwe zimakhudza chitukuko cha mafakitale a cellulose ether
1, kuchuluka kwa mabizinesi opanga, mpikisano wosasamala ndi wowopsa
Cellulose etha ntchito yomanga mkombero ndi lalifupi, kutsogolera mabizinezi zoweta ndi akunja alowa m'munda, kuti chodabwitsa cha kukula pafupipafupi.Pakati pawo, pali mabizinesi ang'onoang'ono opanga, omwe ambiri amakhala ndi ndalama zochepa, luso lochepa laukadaulo, zida zosavuta zopangira, njira zosakwanira zoteteza chilengedwe, komanso kuipitsidwa kwakukulu kwa chilengedwe popanga.Zogulitsa zamtengo wotsika zobwera chifukwa chotsika mtengo zimasefukira pamsika, zomwe zimapangitsa kuti pakhale mitengo yosagwirizana komanso mtundu wazinthu, ndipo msika uli mumpikisano wosagwirizana.M'zaka zaposachedwa, chitetezo cha chilengedwe chatengedwa mozama ndi boma, ndipo zofunikira zamabizinesi opanga zida zakonzedwa bwino.Mabizinesi ena ang'onoang'ono omwe sangathe kukonza ndikukweza adzachoka pamsika pang'onopang'ono, ndipo mpikisano wosagwirizana wa cellulose ether udzakhala wabwino.
2. Makampani apakhomo adayamba mochedwa ndi luso lotsika
Makampani opanga ma cellulose ether adayamba kale m'maiko otukuka, opanga odziwika bwino padziko lonse lapansi ndi omwe amapereka msika wapamwamba kwambiri padziko lonse lapansi, ndipo amadziwa luso laukadaulo laukadaulo wa cellulose ether.China mapadi etere makampani anayamba mochedwa, poyerekeza ndi mayiko otukuka, China chinkhoswe mu kafukufuku ndi kupanga mapadi etere m'munda wa antchito ochepa, mkulu mlingo wa nkhokwe akatswiri talente mwachionekere osakwanira, pali kusiyana kwina mu kafukufuku ndi chitukuko. ndi ukadaulo wogwiritsa ntchito cellulose ether.Kukhudzidwa ndi osakwanira ntchito luso ndi talente reserve, zoweta mapadi etere kupanga mabizinezi kubala mankhwala ambiri, kwa zosowa zenizeni za makasitomala kutsika makasitomala payekha mankhwala zochepa, n'zovuta kukwaniritsa zofuna za makasitomala, kufooketsa anawonjezera phindu la mankhwala ndi msika mpikisano. .
