Kugwiritsa ntchito 1,3-Propanediol m'mafakitale

1,3-Propanediol (PDO)ndi diol yosinthika komanso yosinthika yomwe yakhala yofunika kwambiri m'mafakitale, makamaka chifukwa cha kupanga kwake kochokera ku zinthu zachilengedwe.1,3-propanediolKufunika kwa mafakitale kuli pa malo olumikizirana zinthu zogwira ntchito bwino (makamaka ulusi wa PTT) ndi mankhwala obiriwira, zomwe zimathandiza kuti zinthu zokhazikika komanso zinthu zogwiritsidwa ntchito ndi anthu zisamawononge chilengedwe.

 

·Ma polima ndi nsalu (Ntchito Yaikulu Kwambiri)

Zinthu zopangira za Polytrimethylene Terephthalate (PTT): PDO imaphatikizidwa ndi terephthalic acid kuti ipange PTT. (PTT imagwiritsidwa ntchito kwambiri popanga ulusi wa kapeti, zovala ndi zovala zogwirira ntchito komanso mapulasitiki aukadaulo.)

 

·Zosakaniza ndi Ma Resin

Ingagwiritsidwe ntchito ngati monomer kusintha Unsaturated Polyester Resins (UPRs) zomwe zimapangitsa kuti ikhale yosinthasintha, yolimba, komanso yokhazikika pakugwiritsa ntchito monga marine gel coats, matanki, ndi zida zamagalimoto.

Kupanga Thermoplastic Polyurethanes (TPUs): Ma polyol okhala ndi PDO amatha kupanga ma TPU okhala ndi mphamvu zowonjezera pa nsapato, ziwalo zamkati zamagalimoto, ndi mapayipi osinthasintha.

Amagwiritsidwa ntchito popanga ma polyurethane ogwira ntchito bwino omwe ali ndi kukhazikika kwa UV, kukana mankhwala, komanso kusinthasintha kwa kutentha kochepa kwa Zophimba, Zomatira, Zotsekera, ndi Elastomers (CASE).

 

·Zotsukira Madzi ndi Mafomula Oyeretsera

Imagwira ntchito ngati chosungunulira, chosinthira kukhuthala, komanso chotulutsa utoto. Imathandiza kuletsa dothi, kuletsa kuyikanso kwa nsalu, komanso kumalimbitsa kukhazikika kwa zotsukira za enzyme.

 

·Madzi Ochotsa Icing/Oletsa Icing

Chosakaniza chofunikira kwambiri mu mitundu yambiri ya "anti-icing" ya mitundu ya IV ya Aircraft De-icing Fluids. Chimapereka malo abwino kwambiri oziziritsira ndipo chimapanga filimu yoteteza, yokhuthala yomwe imaletsa kupangika kwa ayezi pamwamba pa ndege kwa nthawi yayitali "yoyimirira" isananyamuke. Ndi yopanda poizoni komanso yoteteza chilengedwe kuposa ma glycols ena achikhalidwe monga ethylene glycol.

 

 

·Kuthekera kogwiritsa ntchito bwino ntchito yomanga njerwa

Monga mankhwala othandiza mkati komanso ochepetsa kuchepa kwa madzi, komanso mankhwala oletsa kuzizira

PDO ndi mankhwala othandiza kwambiri osungira madzi m'chilengedwe. Akasakaniza mu matope kuti apange njerwa, amatha kusunga chinyezi kwa nthawi yayitali ndikuchitulutsa pang'onopang'ono panthawi yomaliza ya simenti. Izi zimachepetsa kwambiri kuuma ndi ming'alu, zimapangitsa kuti simenti ikhale yokwanira komanso yofanana, zimawonjezera mphamvu ndi kuchulukana kwa njerwa, komanso zimathandizira kuti njerwa zisaume bwino.

-Ngati chomangira kapena chosinthira zachilengedwe

PDO ingagwiritsidwe ntchito ngati polyol kuti igwire nawo ntchito yopanga kapena kusintha ma polima (monga polyurethanes, polyester resins), zomwe zingagwiritsidwe ntchito ngati guluu wa ulusi kapena zomangira mkati mwa njerwa, zomwe zimapangitsa kuti umphumphu wonse ukhale wolimba. Chophimba choteteza pamwamba pa njerwa chimapereka ntchito monga kuletsa madzi, kuletsa kuzizira komanso kuletsa kutayira utoto.

 

-Monga chokhazikika cha njerwa zopakidwa thovu kapena zopepuka

Mphamvu zake zoyatsira mpweya zimathandiza kukhazikika kwa kapangidwe ka thovu panthawi yotulutsa thovu, zomwe zimapangitsa kuti ming'alu yamkati mwa njerwa ikhale yofanana komanso yaying'ono. Zotsatira zake, njerwa zopepuka zokhala ndi mphamvu yoteteza kutentha komanso mphamvu zambiri zimapezeka.
