Ma Chips a Polyester Opaka Utoto a Cationic Osawoneka Bwino

ChogulitsaKoreTanthauzo

Ma polyester a Semi-Dull Cationic chips amapangidwa pogwiritsa ntchito copolymerization modification ndi kuyambitsa monomer yachitatu panthawi ya polymerization ya polyester yachikhalidwe. Mwa kuphatikiza magulu enaake a sulfonate ngati malo opaka utoto pa unyolo wa mamolekyu, polyester, yomwe nthawi zambiri imakhala yovuta kupaka utoto, imatha kupaka utoto ndi utoto wa cationic pansi pa atmospheric (ECDP) kapena high-pressure conditions (CDP).

Katundu Waukulu wa Zogulitsa

1.Kuchita bwino kwambiri popaka utoto

Utoto wa cationic umagwirizana kwambiri, ukhoza kupakidwa utoto pogwiritsa ntchito kutentha kwambiri (ECDP grade) kapena kutentha kwambiri (CDP grade). Uli ndi utoto wambiri, mitundu yosiyanasiyana, mithunzi yowala, komanso mtundu wake ndi wosavuta kuupaka.

2. Kusintha Kwabwino Kwa Thupi

Kukana kutentha, kukana hydrolysis, ndi makhalidwe a makina ndi ofanana ndi PET yachizolowezi. Kusintha kwina ndi gawo lachinayi kungapangitse kuti manja a ulusi akhale ofewa komanso kuti ntchito yoletsa kupindika ikhale yabwino.

3. Zotsatira Zapadera Zosakaniza

Mukasakaniza ndi ulusi wamba wa PET kapena cellulosic (monga thonje, viscose), utoto wa bafa imodzi ukhoza kupanga zotsatira zapadera monga kusungitsa koyera, zotsatira za mitundu iwiri yosiyana, kapena zotsatira zamitundu yambiri.

4. Kusinthasintha Kwamphamvu kwa Ntchito

Yoyenera kusakanikirana ndi ma masterbatches ogwira ntchito monga mitundu yoletsa moto, yoletsa mabakiteriya, yochotsa chinyezi, komanso youma mwachangu, zomwe zimathandiza kupanga ulusi wosiyanasiyana, wogwira ntchito komanso wosakhala wa ulusi.

Ma Chips a Polyester Osasinthika a Cationic Dyeable

Tanthauzo la Pakati pa Zamalonda

Chipu cha polyester chosinthidwa bwino chomwe chimapangidwa ndi kusintha kwa copolymerization, chomwe nthawi yomweyo chimayambitsa zigawo za cationic dye site ndi zigawo za phosphorous-based flame retardant zomwe zimagwiritsidwa ntchito kwambiri mu unyolo wa polyester macromolecular.

Imathetsa mavuto a polyester wamba—kudaya utoto kovuta, kufunikira kwa utoto wotentha kwambiri komanso wopanikizika kwambiri, komanso mitundu yochepa. Chogulitsachi chimapaka utoto wowala kwambiri ndi utoto wa cationic pansi pa kutentha kwa mlengalenga, pomwe chimasunga mawonekedwe oyambira a polyester (PET) kwambiri.

Pakadali pano, khalidwe lake loletsa moto limatsimikizira kuti ulusi ndi nsalu sizitha kuyaka nthawi yayitali. Limagwiritsidwa ntchito kwambiri m'mafakitale, m'mafakitale okongoletsera komanso m'mafakitale apadera okhala ndi zofunikira kwambiri kuti utoto uwoneke bwino, kukhudza m'manja komanso magwiridwe antchito otetezeka.

Ubwino Wazinthu Zazikulu

1. Kulephera kwa moto kochokera ku chilengedwe, kotetezeka, kolimba komanso kosamalira chilengedwe

Mosiyana ndi makina osakanikirana oletsa moto, ukadaulo wa copolymerization umagwiritsidwa ntchito, komwe zigawo zoletsa moto zimafalikira mofanana mu matrix ngati gawo la kapangidwe ka polyester macromolecular, zomwe zimapangitsa kuti zizimitse zokha kwa nthawi yayitali komanso kupewa kufalikira kwa moto. Chogulitsachi chilibe halogen, chikugwirizana ndi malamulo azachilengedwe a EU monga RoHS ndi REACH, chimakhala ndi utsi wochepa komanso mpweya woipa wotuluka panthawi yoyaka, zomwe zimapangitsa kuti chikhale chotetezeka komanso chopanda chilengedwe.

2.Kupaka utoto kwabwino kwambiri ndi utoto wowala komanso wodzaza

Imatha kupakidwa utoto pa kutentha kotentha (100°C) popanda chonyamulira, zomwe zimapangitsa kuti mphamvu zisamawonongeke komanso kuti igwiritsidwe ntchito pang'ono. Nsalu zopakidwa utoto zimakhala ndi mtundu wowala, mitundu yonse komanso mtundu wake ndi wosavuta kugwiritsa ntchito, makamaka kukwaniritsa zofunikira pakupanga zinthu zakuda komanso zamitundu yambiri.

3. Katundu wabwino komanso wosavuta kugwira ntchito

Ndi kukhuthala kwa mkati kokhazikika komanso malo oyenera osungunuka, mankhwalawa amakhala ndi kukhazikika kwa kutentha komanso mawonekedwe ozungulira. Ulusi wopangidwawo uli ndi kulimba pang'ono komanso kutalika, komanso kufewa kwa manja, kuthana ndi mavuto monga kuuma ndi kupopera komwe kumapezeka mu ulusi wamba woletsa moto.
