Polybutylene terephthalate, feem ntau yog hu ua PBT, yog qhov siab -}}}} Kev tsim khoom siv cov roj fiber ntau sheaths sheaths. Tab sis dab tsi ua rau nws xws li cov khoom nyiam nyob hauv cov ntawv thov no?
Thaum PBT yog tsim nrog qhov hnyav molecular hnyav, nws ua rau muaj zog tensile lub zog, muaj zog tsis kam, thiab cov tub ntxhais hluas cov modulus. Cov yam ntxwv zoo no ua rau kev xaiv zoo PBT rau cov tub rog xoob, kev tiv thaiv hloov kho qhov muag sab hauv ruaj ntseg thiab ua kev ntseeg.
Ntxiv rau nws cov txiaj ntsig zoo, pbt yog Ester - Raws polymer nrog cov zog, roj, thiab tshuaj lom neeg. Qhov no ua rau nws haum tshwj xeeb rau kev siv hauv kev hnyav lossis sib txawv. Nws tseem pom tau zoo sib xws nrog ntau yam ntawm ntau yam ntawm ntau yam ntawm ntau cov gels thiab cable teb, tiv thaiv cov khoom muaj kev cuam tshuam thiab kev ua tau zoo.
Cov khoom tseem ceeb ntawm PBT muaj xws li:
- Qes shrinkage qis
- High Hydrolysis Kuj
- Tsawg coefficient ntawm linear thermal expansion
- Lub zog tensile ntau tshaj 55 mpa
- Flexural Modulus ntawm 2.2 GPA
- Cov Txheej Txheem Zoo thiab Cov Khoom Siv Hluav Taws Xob
- Siab crystallinity
- Superior resistance rau cov kuab tshuaj, roj, thiab tshuaj lom neeg
- Zoo heev tau ntau heev nrog kho qhov muag cable sau cov ntaub ntawv
Moreover, PBT offers manufacturing benefits thanks to its good melt flow properties, rapid crystallization rate, and short molding cycle-making it both efficient and cost-effective to process.
Tag nrho cov cwj pwm no ua ke ua rau cov khoom siv zoo rau kev tiv thaiv kho qhov muag zoo nkauj, ua kom muaj kev cia siab rau cov tshuaj lom fiber optic
