Lub Ntsiab Lus Txhais ntawm Cov Khoom
Low Carboxylic Proj avClub duavyog tus cwj pwm los ntawm cov ntsiab lus carboxyl qis thiab muaj zog hloov pauv tau. Lawv feem ntau yog pab cov xwm txheej downstream nrog cov kev xav tau yooj yim rau kev ruaj khov ntawm cov khoom siv thiab kev tiv thaiv hydrolysis, xws li kev tsim monofilament.
Cov yam ntxwv tseem ceeb ntawm cov khoom
1.Cov Chaw Nres Tsheb Carboxyl Uas Tswj TauicCov Ntsiab Lus, Txhawb Nqa Cov Kev Xav Tau Tshwj Xeeb
Cov ntsiab lus ntawm cov carboxyl kawg ntawm Low Carboxyliccov khoom siv polyesterraug tswj hwm nruj me ntsis ntawm ≤12% mol / t. Kev hloov kho cov ntsiab lus carboxyl tshwj xeeb tuaj yeem muab tau raws li cov txheej txheem ua haujlwm tshwj xeeb thiab cov xwm txheej thov ntawm cov neeg siv khoom downstream.
2.Cov Qauv Tshuaj Zoo Tshaj Plaws thiab Kev Ruaj Ntseg Zoo Tshaj Plaws
Low Carboxyliccov khoom siv polyestermuaj cov ntsiab lus carboxyl qis dua hauv lawv cov saw hlau molecular, thiab kev faib tawm ntawm cov saw hlau molecular, crystallinity zoo dua, thiab linearity zoo dua. Qhov no muab qee qhov zoo hauv cov khoom siv kho tshuab xws li kev ruaj khov.
3.Kev Tiv Thaiv Hydrolysis Zoo Kawg Nkaus, Haum rau Cov Xwm Txheej Humid
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev ua tau zooLow Carboxyliccov khoom siv polyesteryog lawv txoj kev tiv thaiv hydrolysis:Vim tias pawg carboxyl kawg yog pawg hydrophilic, qhov qis dua nws cov ntsiab lus, qhov tsawg dua nws yuav raug hydrolysis reactions thiab ua rau kev ua haujlwm poob qis thaum nyob hauv qhov chaw noo lossis sib cuag nrog dej.
4.Kev Ua Haujlwm Ruaj Khoov, Hloov Tau Rau Ntau Yam Txheej Txheem
Thaum lub sijhawm ua tiav,Low Carboxyliccov khoom siv polyester qhia ob qho txiaj ntsig tseem ceeb:Nws muaj kev ruaj khov zoo thaum tshav kub, tuaj yeem tswj tau kev ua haujlwm ruaj khov hauv qee qhov kub siab, thiab tsis tshua muaj feem cuam tshuam rau qhov zoo ntawm kev ua haujlwm vim muaj teeb meem xws li kev puas tsuaj los ntawm cua sov. Nws qhov kev sib hloov kuj zoo heev, ua rau kev ua haujlwm tom qab ntawd zoo li kev sib hloov.
5.Cov Xwm Txheej Siv Tau Dav Dav, Tsom Mus Rau Cov Thaj Chaw Uas Muaj Kev Xav Tau Ntau
Raws li cov khoom siv raw spinning,Low Carboxyliccov khoom siv polyestersiv tau los tsim cov ntaub textile nrog qee qhov kev tiv thaiv kev ntxuav thiab kev tiv thaiv deformation, ua tau raws li qhov xav tau yooj yim ntawm cov khaub ncaws nruab nrab mus rau qib siab thiab cov ntaub hauv tsev.
Hauv cov xwm txheej yas engineering qis kawg uas muaj qhov yuav tsum tau ua kom ruaj khov ntawm cov khoom siv (piv txwv li, cov khoom siv hauv tsev me me, cov khoom siv kho tshuab yooj yim),Low Carboxyliccov khoom siv polyestertuaj yeem ua kom ntseeg tau tias kev siv mus sij hawm ntev ntawm cov khoom los ntawm lawv cov khoom siv kho tshuab zoo heev
