Wopanga Mapepala Otsogola a PET

1. Kodi pepala la PET ndi chiyani?

 

PET (Polyethylene terephthalate) ndi thermoplastic yogwiritsidwa ntchito kwambiri m'banja la polyester. PET pulasitiki ndi yopepuka, yamphamvu komanso yolimba. Nthawi zambiri imagwiritsidwa ntchito mumakina opangira chakudya chifukwa cha kuyamwa kwake chinyezi pang'ono, kutentha kochepa, komanso mphamvu zake zotsutsana ndi mankhwala.

 

 

2. Kodi ubwino wa pepala la PET ndi wotani?

 

• Pepala la PET lili ndi mphamvu komanso kulimba kwambiri kuposa PBT. Poyerekeza ndi PBT, lilinso ndi kutentha kwakukulu kwa kutentha (HDT).
• Pepala la PET ndi lolimba kwambiri komanso lopepuka ndipo motero ndi losavuta komanso lothandiza kunyamula.
• Pepala la PET lili ndi kutentha kosiyanasiyana komwe kumagwiritsidwa ntchito, kuyambira -60 mpaka 130°C.
• Pepala la PET lili ndi mpweya wochepa wolowa, makamaka ndi carbon dioxide.
• Pepala la PET silisweka kapena kusweka. Limalephera kusweka ndipo motero, lingagwiritsidwe ntchito m'malo mwa galasi m'malo ena.
• Pepala la PET limadziwika chifukwa cha mphamvu zake zabwino zotchingira chinyezi.
• Pepala la PET lili ndi mphamvu zabwino kwambiri zotetezera magetsi.
• Zipangizo zapulasitiki za pepala la PET zimatha kubwezeretsedwanso ndipo sizowopsa. Mapepala apulasitiki a PET avomerezedwa kuti ndi otetezeka kukhudzana ndi zakudya ndi zakumwa ndi FDA, Health Canada, EFSA ndi mabungwe ena azaumoyo.

 

 

3. Kodi kuipa kwa PET Sheet ndi kotani?

 

• Mphamvu ya mphamvu ndi yotsika kuposa PBT.
• Chifukwa cha kuchepa kwa makristalo, mawonekedwe ake ndi otsika poyerekeza ndi a PBT.
• Zimakhudzidwa ndi madzi otentha.
• Imawopsezedwa mosavuta ndi ma alkali ndi ma alkali amphamvu.
• Kusagwira bwino ntchito kwa kuyaka.
• Amaukiridwa ndi ma ketone, ma hydrocarbons onunkhira bwino komanso a chlorine, ndipo amachotsa ma acid ndi ma bases pa kutentha kwambiri (>60°C).

 

 

4. Kodi ntchito zazikulu za PET Sheet ndi ziti? 

 

Polyethylene Terephthalate/PET imagwiritsidwa ntchito m'mapaketi osiyanasiyana monga tafotokozera pansipa:
Popeza Polyethylene Terephthalate ndi chinthu chabwino kwambiri chotchinga madzi ndi chinyezi, mabotolo apulasitiki opangidwa kuchokera ku PET amagwiritsidwa ntchito kwambiri pamadzi amchere ndi zakumwa zoziziritsa kukhosi zokhala ndi carbonated.
Mphamvu yake yayikulu yamakina imapangitsa mafilimu a Polyethylene Terephthalate kukhala abwino kugwiritsa ntchito poika tepi.
Pepala la PET losayang'ana mozungulira limatha kupangidwa kuti lipange mathireyi opaka ndi matuza.
Kusagwira kwake ntchito kwa mankhwala, pamodzi ndi zinthu zina zakuthupi, kwapangitsa kuti ikhale yoyenera kwambiri poika chakudya.
Mapaketi ena ndi monga mitsuko yolimba yokongoletsera, zotengera zogwiritsidwa ntchito mu microwave, mafilimu owonekera, ndi zina zotero.

 

 

5. Kodi opanga mapepala akuluakulu asanu a PET ku China ndi ati?

 

Huisu Qinye Plastic Group ndi imodzi mwa makampani opanga mapulasitiki aku China komanso ogulitsa mapulasitiki omwe ndi otsogola pamsika.

Mukhozanso kupeza mapepala apamwamba a PET kuchokera ku mafakitale ena, monga,

Jiangsu Jincai Polymer Materials Science And Technology Co., Ltd.
Jiangsu Jiujiu Material Technology Co., Ltd.
Jiangsu Jumai New Material Technology Co., Ltd.
Yiwu Haida Plastic Industry Co., Ltd.

 

 

6. Kodi makulidwe ofala kwambiri a PET Sheet ndi otani?

 

Izi zimatengera zomwe mukufuna, titha kuzipanga kuyambira 0.12mm mpaka 3mm.
Makasitomala amagwiritsa ntchito kwambiri.

• Chipepala cholimba cha PET cha 0.12 mm 
• Chipepala choletsa chifunga cha PET cha 0.25-0.8mm ndi pepala la PET la chithuza 
• Pepala la PET la 1-3mm lotetezera kutsekereza
