Wopereka Chitetezo cha Zachilengedwe Padziko Lonse

Tanthauzo Lalikulu la Chogulitsachi

Low Carboxylic PolyesterCchiunoAmadziwika ndi kuchuluka kochepa kwa carboxyl komanso kusinthasintha kwamphamvu kwa ma processing. Amapereka makamaka zochitika zapansi pamadzi zomwe zimakhala ndi zofunikira zoyambira kuti zinthu zikhale zolimba komanso kukana hydrolysis, monga kupanga monofilament.

Zinthu Zazikulu Zamalonda

1.Chowongolera cha Terminal CarboxylicZamkati, Zothandizira Zofunikira Zosinthidwa

Kuchuluka kwa ma carboxyl otsiriza Low Carboxylictchipisi ta polyesterimayendetsedwa mosamala pa ≤12% mol/t. Kusintha kwa kuchuluka kwa carboxyl komwe kumapangidwa mwamakonda kungaperekedwe malinga ndi ukadaulo wopangira zinthu ndi zochitika za ogwiritsa ntchito makasitomala otsika.

2.Kapangidwe ka Mankhwala Abwino Kwambiri ndi Kukhazikika Kwabwino Kwambiri kwa Makina

Low Carboxylictchipisi ta polyesterali ndi kuchuluka kochepa kwa carboxyl mu unyolo wawo wa mamolekyulu, ndipo kufalikira kwa unyolo wa mamolekyulu, crystallinity ndi yabwino, ndipo linearity ndi yabwino. Izi zimapatsa ubwino wina mu mawonekedwe a makina monga kukhazikika.

3.Kukana Kwambiri kwa Hydrolysis, Koyenera Zochitika Zonyowa

Chimodzi mwa zinthu zofunika kwambiri pa ntchitoLow Carboxylictchipisi ta polyesterKodi kukana kwawo hydrolysis ndi chiyani:Popeza gulu la terminal carboxyl ndi gulu lokonda hydrophilic, kuchuluka kwake kukakhala kochepa, sizingakhale zovuta kuchita hydrolysis reactions ndikuyambitsa kuwonongeka kwa magwiridwe antchito akakhala pamalo ozizira kapena akakumana ndi madzi.

4.Kugwira Ntchito Kokhazikika, Kosinthika ku Njira Zambiri

Pa nthawi yokonza,Low Carboxylictchipisi ta polyester onetsani zabwino ziwiri zazikulu:Ili ndi kutentha kokhazikika, imatha kugwira ntchito bwino pansi pa kutentha kwambiri, ndipo nthawi zambiri siingakhudze ubwino wa kukonza chifukwa cha mavuto monga kuwonongeka kwa kutentha. Kusinthasintha kwake ndikwabwino, zomwe zimathandiza kukonza bwino pambuyo pake monga kupota.

5.Zochitika Zosiyanasiyana Zogwiritsira Ntchito, Kuyang'ana Kwambiri Paminda Yofunidwa Kwambiri

Monga zinthu zopangira zozungulira,Low Carboxylictchipisi ta polyesteringagwiritsidwe ntchito kupanga ulusi wa nsalu wokhala ndi kukana kusamba ndi kusinthasintha kwa zinthu, kukwaniritsa zosowa zoyambira za zovala zapamwamba komanso nsalu zapakhomo. 

Mu mapulasitiki otsika mtengo okhala ndi zofunikira zambiri kuti zinthu zikhale zolimba (monga zikwama zazing'ono zapakhomo, zida zosavuta zamakina),Low Carboxylictchipisi ta polyesterakhoza kutsimikizira kuti ziwalozo zikugwiritsidwa ntchito bwino kwa nthawi yayitali kudzera mu luso lawo labwino kwambiri la makina
