Kiimiko noocee ah ayay Shiinuhu u dhoofiyeen Thailand?
Horumarinta suuqa kiimikada ee Koonfur-bari Aasiya waxay ku salaysan tahay koox macaamiil oo badan, shaqaale jaban, iyo siyaasado dabacsan. Dadka qaar ee warshadaha ku jira ayaa sheegaya in jawiga suuqa kiimikada ee hadda ka jira Koonfur-bari Aasiya uu aad ugu eg yahay kan Shiinaha sanadihii 1990-meeyadii. Iyadoo la eegayo horumarka degdegga ah ee warshadaha kiimikada ee Shiinaha, isbeddelka horumarinta ee suuqa Koonfur-bari Aasiya ayaa si isa soo taraysa u caddaatay. Markaa, waxaa jira shirkado badan oo mustaqbalka eegaya oo si firfircoon u ballaarinaya warshadaha kiimikada ee Koonfur-bari Aasiya, sida silsiladda warshadaha epoxy propane iyo silsiladda warshadaha propylene, iyo kordhinta maalgashigooda suuqa Vietnam. (1) Madow kaarboon waa kiimikada ugu weyn ee laga dhoofiyo Shiinaha una dhoofiyo Thailand Sida laga soo xigtay tirakoobka xogta kastamka, cabbirka kaarboonka... -
Koror weyn oo ku yimid wax soo saarka danabka sare ee gudaha iyo ciriiriga farqiga qiimaha toosan
Tan iyo 2020, warshadaha polyetylen-ka ee gudaha ayaa galay wareeg ballaarin dhexe, awoodda wax soo saarka sanadlaha ah ee PE-ga gudaha ayaa si degdeg ah u korodhay, iyadoo celcelis ahaan heerka kobaca sanadlaha ah uu ka badan yahay 10%. Soo saarista polyetylen-ka gudaha laga soo saaro ayaa si degdeg ah u korodhay, iyadoo la isku daray badeecadaha iyo tartanka xooggan ee suuqa polyetylen-ka. Inkasta oo baahida loo qabo polyetylen-ku ay sidoo kale muujisay isbeddel koboc sannadihii ugu dambeeyay, haddana kobaca baahida ma uusan ahayn mid degdeg ah sida heerka kobaca saadka. Laga soo bilaabo 2017 ilaa 2020, awoodda wax soo saarka cusub ee polyetylen-ka gudaha ayaa inta badan diiradda saartay noocyada danab hooseeya iyo kuwa toosan, mana jirin qalab danab sare leh oo laga howlgaliyay Shiinaha, taasoo keentay waxqabad xooggan oo suuqa danab sare leh. Sannadkii 2020, maadaama qiimuhu kala duwan yahay... -
Mustaqbalka: ilaali isbeddellada baaxadda, abaabul oo raac tilmaamaha dusha sare ee wararka
Maajo 16, qandaraaska Liansu L2309 wuxuu furmay 7748, iyadoo qiimaha ugu yar uu ahaa 7728, qiimaha ugu badanna uu ahaa 7805, qiimaha xidhitaankana uu ahaa 7752. Marka la barbardhigo maalintii hore ee ganacsiga, waxay korodhay 23 ama 0.30%, iyadoo qiimaha dejinta uu ahaa 7766 iyo qiimaha xidhitaanka uu ahaa 7729. Kala duwanaanshaha 2309 ee Liansu wuu isbeddelay, iyadoo hoos u dhac yar uu ku yimid boosaska iyo xidhitaanka khadka togan.

Waa maxay filimka Overwrap-ka Polypropylene ee Biaxially Oriented?
Filim polypropylene (BOPP) oo Biaxially Oriented Biaxially waa nooc ka mid ah filim baakad dabacsan. Filim polypropylene overwrap ah oo Biaxially Oriented waxaa lagu fidiyaa jihooyinka mashiinka iyo kuwa isdhaafka ah. Tani waxay keentaa jiheynta silsiladda molecular labada jiho. Noocan filimka baakadaha dabacsan waxaa lagu sameeyaa habka wax soo saarka tuubo. Xumbo filim oo qaab tuubo ah ayaa la buufiyaa oo la kululeeyaa ilaa uu jilco (tani way ka duwan tahay barta dhalaalaysa) waxaana lagu fidiyaa mashiinno. Filimku wuxuu fidsan yahay inta u dhaxaysa 300% - 400%. Haddii kale, filimka waxaa sidoo kale lagu fidin karaa habka loo yaqaan wax soo saarka filimka Tenter-frame.

Noocyada polypropylene.
Molecules-ka Polypropylene waxay ka kooban yihiin kooxo methyl ah, kuwaas oo loo qaybin karo isotactic polypropylene, atactic polypropylene iyo syndiotactic polypropylene sida waafaqsan habaynta kooxaha methyl. Marka kooxaha methyl-ka lagu habeeyo isla dhinaca silsiladda ugu weyn, waxaa loo yaqaan isotactic polypropylene; haddii kooxaha methyl-ka si aan kala sooc lahayn loogu qaybiyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan atactic polypropylene; marka kooxaha methyl-ka si is beddel ah loogu habeeyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan syndiotactic. polypropylene. Soo saarista guud ee resin polypropylene, waxa ku jira qaab-dhismeedka isotactic (oo loo yaqaan isotacticity) waa qiyaastii 95%, inta soo hartayna waa atactic ama syndiotactic polypropylene. Resin polypropylene-ka hadda laga soo saaro Shiinaha waxaa loo kala saaraa sida... -
Isticmaalka resin pvc ah oo koollo ah.
Waxaa lagu qiyaasay in sannadkii 2000, wadarta isticmaalka suuqa caalamiga ah ee resin koollada PVC ay ahayd qiyaastii 1.66 milyan oo t/a. Shiinaha, resin koollada PVC waxay inta badan leedahay codsiyada soo socda: Warshadaha maqaarka macmalka ah: isu dheelitirka guud ee suuqa iyo baahida. Si kastaba ha ahaatee, iyadoo ay saamaysay horumarinta maqaarka PU, baahida loo qabo maqaar macmalka ah ee Wenzhou iyo meelaha kale ee waaweyn ee lagu isticmaalo resin koollada waxaa ku xiran xaddidaadyo gaar ah. Tartanka u dhexeeya maqaarka PU iyo maqaarka macmalka ah waa mid aad u daran. Warshadaha maqaarka sagxadda: Iyada oo ay saamaysay baahida sii yaraanaysa ee maqaarka sagxadda, baahida loo qabo resin koollada ee warshadahan ayaa sannadba sannadka ka dambeeya hoos u dhacaysay sannadihii la soo dhaafay. Warshadaha agabka galoofiska: baahida ayaa aad u weyn, oo inta badan la soo dejiyo, taas oo ka tirsan farsamaynta lammaane la keenay... -
Isticmaalka soodhaha caustic wuxuu ku lug leeyahay meelo badan.
Soodhaha Caustic waxaa loo qaybin karaa soodhaha flake, soodhaha granular iyo soodhaha adag iyadoo loo eegayo qaabkeeda. Isticmaalka soodhaha caustic waxay ku lug leedahay beero badan, soo socda waa hordhac faahfaahsan oo adiga kuu ah: 1. Batrool la safeeyey. Ka dib marka lagu dhaqo aashitada sulfuric, badeecooyinka batroolka ayaa wali ka kooban walxo aashito ah, kuwaas oo ay tahay in lagu dhaqo xal sodium hydroxide ka dibna lagu dhaqo biyo si loo helo badeecooyin la safeeyey. 2. daabacaadda iyo rinjiyeynta Inta badan waxaa loo isticmaalaa rinjiyeyaasha indigo iyo rinjiyeyaasha quinone. Habka rinjiyeynta ee rinjiyeynta weelka, xalka soodhaha caustic iyo sodium hydrosulfite waa in loo isticmaalaa si loo yareeyo leuco acid, ka dibna loo oxidize xaaladda asalka ah ee aan milmi karin iyadoo la adeegsanayo oksaydhiyeyaasha ka dib rinjiyeynta. Ka dib marka dharka suufka lagu daaweeyo xal soodhaha caustic, shamaca, dufanka, istaarijka iyo walxaha kale ... -
Soo kabashada baahida PVC ee caalamiga ah waxay ku xiran tahay Shiinaha.
Marka la gaaro 2023, baahida gaabiska ah ee gobollo kala duwan awgeed, suuqa caalamiga ah ee polyvinyl chloride (PVC) ayaa weli wajahaya hubanti la'aan. Inta badan 2022, qiimaha PVC ee Aasiya iyo Mareykanka ayaa muujiyay hoos u dhac weyn wuxuuna hoos u dhacay ka hor inta uusan gelin 2023. Marka la gaaro 2023, gobollo kala duwan, ka dib markii Shiinuhu uu wax ka beddelay siyaasadihiisa ka hortagga iyo xakamaynta cudurrada faafa, suuqu wuxuu filayaa inuu ka jawaabo; Mareykanka ayaa laga yaabaa inuu sii kordhiyo heerka dulsaarka si loola dagaallamo sicir bararka loona xakameeyo baahida PVC ee gudaha Mareykanka. Aasiya, oo ay hoggaamineyso Shiinaha, iyo Mareykanka ayaa ballaariyay dhoofinta PVC iyadoo baahida caalamiga ah ee daciifka ah ay jirto. Yurub, gobolku wali wuxuu wajihi doonaa dhibaatada qiimaha tamarta sare iyo hoos u dhaca sicir bararka, waxaana laga yaabaa inaysan jiri doonin soo kabasho waara oo ku timaadda faa'iidada warshadaha. ...
