Para Aramid xov paj

Ultra-High Tensile Mechanical Traits ntawm Para Aramid Xov Paj

Qhov no para-aramid yarn, uas yog ua los ntawm PPTA (para-aramid) polymer, yog tam sim no lub zog tshaj lag luam organic fiber ntau ua thoob ntiaj teb. Nws muaj kev sib xyaw ua ke ntawm lub teeb yuag thiab thauj khoom tsis sib xws ntawm lub teeb yuag thiab thauj khoom- muaj peev xwm ua rau hnyav- lub luag haujlwm tiv thaiv thiab kev siv zog ntxiv, nrog rau lub zog tensile tsib mus rau rau npaug ntawm cov hlau hlau thiab qhov hnyav tsuas yog ib qho - tsib ntawm cov hlau hlau. Cov xov paj nthuav tawm qhov kev ruaj ntseg zoo tshaj plaws nyob rau hauv lub sijhawm ntev thiab rov ua dua cyclic hnav vim nws qhov tshwj xeeb siab elastic modulus thiab me ntsis elongation thaum so.

Nws muaj qhov tseem ceeb, ntev -ntev nplaim taws retardancy thiab nws tus kheej- tua qhov zoo, thiab nws tsis muaj cov molten droplets thaum raug rau qhov hluav taws kub. Nws khiav hauv qhov kub thiab txias ntau yam, los ntawm -196℃mus rau qhov kev pabcuam txuas ntxiv ntawm 204℃.Nyob rau hauv kev sib tw maritime chaw thiab kev ua tshuaj, nws tsis kam mus rau acids, alkalis, thiab organic solvents guarantees kev ncaj ncees.

Tag Nrho Cov Khoom Series & Xaus Kev Lag Luam Layout ntawm Para Aramid Yarn

Ntxiv nrog rau cov xov paj txuas ntxiv thiab cov xov paj spun tsim los ntawm crimped staple fibers, peb cov kab ntau ntawm para-aramid yarn khoom kuj suav nrog cov pulp thiab tws fibers ua cov khoom siv derivative. Cov spun yarns yog zoo meej rau kev txiav- hnab looj tes tiv thaiv thiab tiv thaiv woven fabrics vim lawv muaj linear ceev ntawm 1.5-4 denier thiab tuaj nyob rau hauv tus qauv txiav ntev ntawm 38 hli, 51 hli, thiab 76 hli. Nruam cov qauv filament ncua ntawm 600 mus rau 9000 denier, nrog rau theem pib, siab - lub zog, thiab siab - qib modulus uas tuaj yeem hloov kho rau kev siv xws li cov tsho tiv thaiv mos txwv thiab kho qhov muag cable. Cov khoom siv tiv thaiv tus kheej, cov khoom siv roj hmab sib xyaw, cov khoom siv dav hlau sib sib zog nqus, thiab cov khoom siv raw rau kev sib khi thiab cov khoom sib txhuam yog qhov tseem ceeb ntawm daim ntawv thov.

Tensile zog, abrasion tsis kam, thiab thermal shrinkage yog tag nrho cov kuaj nyob rau hauv rau txhua batch. Peb muaj cov saw hlau sib xyaw ua ke uas suav nrog txhua yam los ntawm cov xov xov sib tw mus rau monomer polymerization, thiab peb muaj cov kws tshaj lij kws tshaj lij ntawm cov neeg ua haujlwm uas tuaj yeem txiav cov qauv raw khoom rau cov kev xav tau tshwj xeeb ntawm peb cov neeg siv khoom cov kab ntau lawm.
