Dab tsi yog polyethylene terephthalfate rau lub raj mis ntau lawm 25038-59-9?
Polyethylene (Tsiaj, Cas 25038-59-9}}) yog ib lub thermondension synthesized ntawm paryescthalic acid thiab ethylene glycol. Nws cov mis molecular yog (c₁₀h₈o₄) ₙ (qhov uas n sawv cev rau qib ntawm polymerization). Cov npe Aliases suav nrog Poly (Ethylene Terephthalate) thiab polyethylene terephthalate (tsiaj).
Tsiaj zoo li tsis muaj xim rau lub teeb daj granular tau nrog lub taw tes melular ntawm 250-255 degree ntawm 1.68 g / ml (ntawm 25 degree). Nws yog insoluble hauv dej tab sis soluble hauv cov kuab tshuaj muaj kuab tshuaj xws li Phenol. Thermally, nws ua kom muaj kev pabcuam kub ntev tsis tau tshaj 120 degree thiab luv luv rau hydrolysis nyob rau hauv cov acid muaj zog, muaj zog alkali, lossis dej vapor chaw.

Kev siv
Ntim:
Tus tsiaj yog siv los ua cov yeeb yaj kiab Polyester (piv txwv li, fwj yas rau cov khoom noj, ntim khoom noj khoom haus (piv txwv li cov khoom siv kom zoo nkauj), thiab cov khoom siv kom zoo nkauj, thiab cov khoom siv hluav taws xob.
Fibers:
Nws yog tsim mus rau hauv polyester staple fibers thiab cov filaments rau textiles thiab khaub ncaws (riam phom), ntaub pua plag tsev (ntaub pua plag tsev), thiab cov ntaub pua tsev (hlua), canvas).
Cov Ntaub Ntawv Kev Nyab Xeeb
TOXICITY: tus tsiaj ntshiab yog tsis muaj tshuaj lom, tab sis monomers yuav raug tso tawm thaum ethylene glycol muaj tsawg toxicity).
Kev Raug Mob Raug: Cov plua tshauv hauv huab cua yuav tsum tau tswj nyob rau ntawm tsawg dua lossis sib npaug rau 5 mg / mg (Lavxias qauv).
Cia: Cia li mus deb ntawm lub teeb thiab qhuav, zam kev sib cuag nrog cov muaj zog acids thiab alkalis.
