Igitambaro cyashongeshejwe kirimo gusohoka koko | JINHAOCHENG

Igitambaro cyashongeshejwe kirimo gusohoka koko! Reka dukurikireuruganda rukora imyenda ishongagusobanukirwa:

Ikoranabuhanga rya Meltblown fabric ryatangiye mu myaka ya 1950, ubwo Leta Zunze Ubumwe za Amerika, kugira ngo zikusanye uduce duto twa radiation mu kirere cyo hejuru kugira ngo zikore ibikoresho byo kuyungurura birebire cyane, zakoze polymer ishongeshejwe ikoresheje ubushyuhe n'umuvuduko w'umwuka, zikora ikoranabuhanga ry'imyenda idaboshye mu buryo butaziguye.

Iri koranabuhanga rihuza ikoranabuhanga ryo gutunganya ibikoresho bya polymer mu nganda zikora imiti n'ikoranabuhanga ryo gukora ibikoresho bidaboshye mu nganda zikora imyenda, rigakora ikoranabuhanga rishya mu rwego rw'ubumenyi bw'ibikoresho kugira ngo hakorwe ibikoresho bishya kandi byiza byo kuyungurura imiti bidaboshye.

Ibikoresho fatizo by'igitambaro cyo gushonga ni polypropylene ifite igipimo cyo gushonga kinini.

Uko igipimo cyo gushonga cya polypropylene kiri hejuru, ni ko fibre iba nziza, kandi ni ko igitambaro cyashongeshejwe kirushaho kuyungurura neza.

Polypropylene ni polymer ikorwa n'uburyo bwo kongeramo propylene. Ibikoresho byera bisa n'ibishishwa, bibonerana kandi bigaragara neza. Ubucucike ni 0.89 ~ 0.91g / cm3, bishobora gushya, aho gushonga ni 165℃, byoroha kuri 155℃, kandi ubushyuhe ni -30 ~ 140℃

Munsi ya 80℃ ishobora kurwanya aside, alkali, umunyu n'ibindi bintu bitandukanye byangiza ibidukikije, ishobora kwangirika bitewe n'ubushyuhe bwinshi n'ubushyuhe. Polypropylene ikoreshwa cyane mu myenda, mu myenda n'ibindi bicuruzwa bya fibre, mu bikoresho by'ubuvuzi, mu modoka, mu magare, mu bikoresho bisimbura ibindi, mu miyoboro y'ubwikorezi, mu bikoresho bya shimi n'ibindi bikorwa, ikoreshwa kandi mu biribwa, mu gupfunyika imiti.

Turi uruganda rukora imiti ishonga, ibicuruzwa ni ibi bikurikira:KF94 yashongeshejwe n'amazi,BFE99 yashongeshejwe,pp yashongeshejwe,n95 yashongeshejwe;Ntutinye kutwandikira kugira ngo ubone ibiciro bishya ~
