Chakumapeto kwa zaka za m'ma 1980, China idayamba kupanga mayunitsi opaka utoto motsatizana.Zambiri mwazinthuzi zidamangidwa m'mafakitale achitsulo ndi zitsulo komanso mabizinesi olumikizana, ndipo zida zopangira utoto zidatumizidwa kuchokera kunja.Pofika mchaka cha 2005, bolodi lopaka utoto wapanyumba linali litafikira matani 1.73 miliyoni, zomwe zidapangitsa kuti ntchito yawo ikhale yochulukirapo.Baosteel, Anshan Chitsulo ndi zitsulo, Benxi Chitsulo ndi zitsulo, Shougang, Tangshan Chitsulo ndi zitsulo, Jinan Chitsulo ndi zitsulo, Kunming Chitsulo ndi zitsulo, Handan Chitsulo ndi zitsulo, Wuhan Chitsulo ndi zitsulo, Panzhihua Chitsulo ndi zitsulo ndi zina lalikulu boma chitsulo ndi mabizinesi zitsulo ndi mkulu unit mphamvu ndi mlingo zida.Iwo apanga motsatizana mayunitsi ❖ kuyanika mitundu ndi luso lakunja ndi mphamvu kupanga pachaka matani 120000 ~ 170000.
Nthawi yomweyo, kupanga matabwa okhala ndi utoto omwe amaperekedwa ndi mabizinesi ambiri apadera nthawi zambiri amatenga zida zapakhomo, zokhala ndi mphamvu zochepa zopangira, koma zimayamba mwachangu komanso ndalama zochepa.Zogulitsazo zimakhala zopangira zida zomangira komanso mafakitale okongoletsa.Kuphatikiza apo, likulu lakunja ndi likulu la Taiwan adafikanso kuti amange mayunitsi opaka utoto, koma ambiri aiwo amakhala m'mphepete mwa nyanja.Kuyambira 1999, ndi chitukuko cha msika wokutira mbale zamitundu, kupanga ndi kugwiritsa ntchito mbale zokhala ndi utoto zalowa m'nthawi yakukula mwachangu.Kuchokera mu 2000 mpaka 2004, kupanga kunakula pamlingo wa 39.0%.Pofika m'chaka cha 2005, mphamvu ya dziko kupanga mbale TACHIMATA mtundu anali oposa 8 miliyoni matani / chaka, ndi angapo mayunitsi TACHIMATA mtundu anali akumanga, ndi okwana dziko mphamvu yopanga matani oposa 9 miliyoni / chaka.
Mavuto omwe alipo: 1 Ngakhale kuti mphamvu yopangira mphamvu yopangira zida zomangira zopangira zomangira yotentha ndi yayikulu, pali kusowa kwa mbale zabwino zomangira monga lathyathyathya-kuviika kanasonkhezereka chitsulo koyilo popanda zinki maluwa ndi nthaka aloyi TACHIMATA zitsulo koyilo;2. Mitundu ndi mtundu wa zokutira zapakhomo sizingakwaniritse zofunikira.Mtengo wokwera wa zokutira zotumizidwa kunja umachepetsa mpikisano.Filimu ya pulasitiki yofunikira pa mbale yamtundu wa filimu ikufunikabe kutumizidwa kunja, ndipo pali kusowa kwa mbale yamtundu wapamwamba kwambiri yokhala ndi zokutira wandiweyani, magwiridwe antchito, mphamvu zazikulu ndi mitundu yolemera;3. Zogulitsazo sizikhala zokhazikika, zomwe zimapangitsa kuti chuma chiwonongeke kwambiri.Pali mayunitsi otsika kwambiri omwe ali ndi mphamvu zosakwana matani 40000 / chaka, ndipo pali mavuto pamtundu wazinthu komanso kuteteza zachilengedwe;4. Pali mayunitsi opaka utoto ochuluka kwambiri ku China, omwe amaposa zomwe msika ukufunikira, zomwe zimapangitsa kuti pakhale kutsika kwa magwiridwe antchito amitundu yambiri yopaka utoto ngakhalenso kuzimitsa.
Chitukuko:
Choyamba, kugwiritsa ntchito gawo lapansi lapamwamba kumafuna zofunikira zapamwamba komanso zapamwamba zapamtunda, mawonekedwe ndi kulondola kwapang'onopang'ono kwa gawo lapansi.Ntchito panja, monga yaing'ono zinki maluwa lathyathyathya otentha-kuviika kanasonkhezereka zitsulo koyilo ndi sanali nthaka maluwa lathyathyathya otentha-kuviika kanasonkhezereka zitsulo koyilo, nthaka aloyi otentha-kuviika kanasonkhezereka koyilo kukwera mu nthawi;Ntchito m'nyumba, monga kanasonkhezereka zitsulo koyilo, TACHIMATA pepala ozizira adagulung'undisa ndi koyilo zotayidwa.
Chachiwiri, kusintha njira pretreatment ndi pretreatment madzi.Pokhala ndi zida zotsika mtengo komanso zotsika mtengo, zakhala njira yodziwika bwino, ndikuwongolera kukhazikika, kukana dzimbiri komanso kuteteza chilengedwe kwamadzi opangira mankhwala.
Chachitatu, chitukuko cha zokutira latsopano ndi kusintha poliyesitala ambiri, polyvinylidene fluoride (PVDF) ndi pulasitiki sol kupeza wapamwamba mtundu reproducibility, UV kukana, kukana sulfure dioxide ndi kukana dzimbiri;Pangani zokutira zogwira ntchito monga kukana kuwononga chilengedwe komanso kuyamwa kutentha.
Chachinayi, zida zamagulu ndi zangwiro.Mwachitsanzo, makina atsopano owotcherera, makina atsopano okutira mipukutu, ng'anjo zowotchera bwino, ndi zida zapamwamba zokha zimagwiritsidwa ntchito.
Chachisanu, ukadaulo wopangira ma embossing ozizira wakhala njira yachitukuko chifukwa cha mtengo wake wotsika, mawonekedwe okongola, kumverera kwa mbali zitatu komanso mphamvu yayikulu.
Chachisanu ndi chimodzi, kulabadira zosiyanasiyana, functionalization ndi mkulu kalasi ya mankhwala, monga zakuya zojambula mtundu ❖ kuyanika bolodi, "grapefruit khungu" utoto ❖ kuyanika bolodi, odana ndi malo amodzi utoto ❖ kuyanika bolodi, kuipitsidwa zosagwira mtundu ❖ kuyanika bolodi, mkulu kutentha mayamwidwe mtundu. coating board, etc.
Zomwe zikuchitika ku China ndikuti opanga mbale zopaka utoto amasamala kwambiri zamtundu wa magawo omwe amagwiritsidwa ntchito popanga mbale zokutira zamitundu, ndipo amakhala ndi zofunikira zapamwamba komanso zapamwamba pakupanga kwawo, zomwe zimapangitsa kuti mbale zokutira zamitundu zizikhala nazo. chopereka chabwino kwambiri pakupanga.Kuphatikiza apo, zida zopangira mbale zokutira zamitundu ndizotsogola, zomwe zimapangitsa kuti mbale zokutira zamtundu zizikhala zodziwikiratu popanga, zomwe sizimangopulumutsa mtengo, komanso zimapulumutsa antchito ambiri, Komanso, pali zambiri komanso zodziwikiratu. opanga mitundu yokutidwa mbale zambiri, ndi mpikisano msika ukukwera kwambiri.Kupititsa patsogolo khalidwe la mankhwala ndi kuchepetsa mtengo wopangira mankhwala kwakhala chizolowezi chofala kwa opanga mbale zopaka utoto.Zopangidwa ndi bolodi zopaka utoto zakhala zochulukirachulukira.Ma board okhala ndi mitundu yosiyanasiyana amatha kugwira ntchito zosiyanasiyana, zomwe zimapangitsa kuti msika wa board board ukhale wosangalatsa kwambiri.
