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. Farsamadan, polymer-yada waxaa lagu soo saaraa duub la qaboojiyey (sidoo kale loo yaqaan xaashida saldhigga) waxaana lagu sawiraa jihada mashiinka. Filimka Tenter-frame-ka ayaa na soo saaraya... -

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.

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. ... -
Waa maxay saameynta dhulgariir xooggan oo ka dhacay Turkiga uu ku leeyahay polyethylene?
