Indwangu encibilikisiwe iyaphuma ngempela! Ake silandeleumenzi wendwangu encibilikisiweukuqondisisa:
Ubuchwepheshe bendwangu ye-Meltblown baqala ngawo-1950, lapho i-United States, ukuze iqoqe izinhlayiya ezinemisebe emoyeni ongaphezulu ukuze ithuthukise izinto zokuhlunga ezi-ultrafine, ukuthuthukiswa kwesimo esincibilikisiwe se-polymer ngaphansi kwesenzo sokushisa nokugeleza komoya, kukhiqiza ngqo ubuchwepheshe bendwangu engalukiwe.
Lobu buchwepheshe buhlanganisa ubuchwepheshe bokucubungula izinto ze-polymer embonini yamakhemikhali kanye nobuchwepheshe bokukhiqiza izinto ezingalukiwe embonini yezindwangu, kwakha ubuchwepheshe obusha emkhakheni wesayensi yezinto zokwakha ukuze kwenziwe izinto zokuhlunga zamakhemikhali ezingalukiwe ezintsha nezisebenzayo.
Izinto zokusetshenziswa zendwangu yokufutha encibilikayo yi-polypropylene ene-index ephezulu yokuncibilika.
Uma inkomba yokuncibilika kwe-polypropylene iphakeme, i-fiber incane kakhulu, futhi kungcono ukuhlungwa kwendwangu efafazwe ngokuncibilika.
I-Polypropylene iyi-polymer eyakhiwe ukusabela kokwengeza kwe-propylene. Izinto ezimhlophe ezifana ne-wax, zisobala futhi zikhanya ngokubukeka. Ubuningi bungu-0.89 ~ 0.91g/cm3, indawo yokuncibilika evuthayo ingu-165℃, ithambile ku-155℃, kanti izinga lokushisa lingu-30 ~ 140℃
Ngaphansi kwama-80℃ kungamelana ne-asidi, i-alkali, isixazululo sikasawoti kanye nezinhlobo ezahlukene zezinyibilikisi eziphilayo kanye nokugqwala, kungabola ngaphansi kokushisa okuphezulu kanye ne-oxidation. I-Polypropylene isetshenziswa kabanzi ezingutsheni, ezingutsheni zokulala kanye neminye imikhiqizo yefayibha, imishini yezokwelapha, izimoto, amabhayisikili, izingxenye ezisele, amapayipi okuthutha, izitsha zamakhemikhali kanye neminye imikhiqizo, futhi isetshenziswa ekudleni, emaphaketheni emithi.
Siyifektri yokufutha encibilikisayo, imikhiqizo yile:I-KF94 meltblown,I-BFE99 meltblown,ukuncibilika kwe-pp okupheshulwe,i-n95 meltblown;Sicela ungangabazi ukuxhumana nathi ukuthola ikhotheshini yakamuva ~
