Optical fiber inozadza Jelly
Tsanangudzo Pfupi
Iyo optical fiber cable indasitiri inogadzira optical fiber tambo nekuvharira iyo optical fibers mune polymeric sheathing. Jelly inoiswa pakati pepolymeric sheathing uye optical fiber. Chinangwa chejelly iyi ndechekupa kudzivirira kwemvura uye sechivharo pakukotama kushushikana uye madhiri.Zvekuita sheathing zvinhu zviri polymeric muzvisikwa zvine polypropylene (PP) uye polybutylterepthalate (PBT) iri iyo inonyanya kushandiswa sheathing zvinhu. Iyo jelly inowanzova isiri-Newtonian mafuta.
Iyo isiri-Newtonian hunhu inobvumira jelly kuonda kunze panguva yekugadziriswa uye kugadzika mushure mekugadzirisa shear masimba abviswa. Maparamendi akakosha anopa maitiro anodiwa ari viscosity pamhando dzakasiyana dzeshear uye kushushikana kwegoho. Kazhinji jelly inogadzirwa nemafuta uye inorganic kana organic thickener. Inorganic thickeners anoshandiswa kubva paorganic clays kusvika silica. Aya makobvu anomiswa mumafuta e-hydrophobic akadai semafuta emaminerari kana mafuta ekugadzira. Pamusoro pezvo, ma stabilizer anogona kuiswa kuti ave nechokwadi chekugadzikana kweoxidative yemusanganiswa.
● XF-400 inopindirana ne acrylic resin coatings uye polymer zvinhu zve fiber uye cable applications.
● Zvinokurudzirwa kuti zvinhu zvose zvepolymer zvinosangana nepaste zviongororwe kuenderana panguva yekushandiswa.
● XF-400 yakagadzirirwa kutonhora kuzadza nzira inodzivisa voids nekuda kwekunamatira shrinkage.
