Non woven polypropylene vs polyester

Mu gwero la zinthu zopanda nsalu zopangira, pali ulusi wachilengedwe, monga ubweya, etc; Ulusi wa inorganic, monga ulusi wagalasi, ulusi wazitsulo, ndi ulusi wa kaboni; Ulusi wopangidwa, monga ulusi wa poliyesitala, ulusi wa polyamide, ulusi wa polyacrylonitrile, ulusi wa polypropylene, ndi zina zotero. Pakati pawo, nsalu zopangira nsalu zopanda nsalu zimagwiritsidwa ntchito kwambiri, choncho ulusi wa polyester ndi polypropylene nthawi zambiri zimawonekera pamaso pa anthu. Ndiye pali kusiyana kotani pakati pa awiriwa?

Mfundo zopangira zosiyana

Ulusi wa polyester umapangidwa makamaka ndi poliyesitala monga chopangira chachikulu, ndikuwonjezera kuchuluka kwa magwiridwe antchito a masterbatch. Kachulukidwe kazinthuzo ndi 136g/cm3, ndipo amasungunuka mu zosungunulira monga phenol tetrachloroethane ndi ortho chlorophenol. Imakhala ndi mayamwidwe otsika kwambiri, kukana kwa asidi, kukhazikika kwamankhwala poyerekeza ndi polyamide, komanso kukana kuwala. Ulusiwo siwophwanyika kapena wopunduka mkati mwa kutentha kwa -40 ℃ mpaka +250 ℃. Ulusi uliwonse umakhala wodziyimira pawokha ndipo umakhala ndi mphamvu zotsatsira ndi asphalt, womwenso ndi mafuta a petroleum. Ili ndi ma adsorption abwino komanso kubalalitsidwa pakati.

Ulusi wa polypropylene ndi mtolo wamphamvu kwambiri wa polypropylene ngati ulusi wa monofilament wokonzedwa ndi kutentha kwa propylene based monomers kutentha kwambiri ndikuwonjezera zopangira ma polymerization. Ili ndi mawonekedwe a njira yosavuta yosakanikirana, yotsika mtengo, komanso magwiridwe antchito abwino kwambiri.

Zosiyana katundu

1. Potengera zakuthupi:

Polypropylene ndi yopepuka komanso imakhala ndi mphamvu zambiri za ulusi, koma kukana kwake kuvala komanso kukana kutentha kwambiri ndizosauka. Ulusi wa polyester uli ndi mphamvu zolimba komanso zolimba, komanso kutentha ndi kukana kwa mankhwala, zomwe zimapangitsa moyo wautali wautumiki.

2. Pankhani ya mankhwala:

Polypropylene imakhala ndi mankhwala okhazikika, samawonongeka mosavuta ndi ma acid, alkalis, ndi zina zotero, ndipo ilibe zinthu zoopsa komanso zovulaza. Ulusi wa polyester uli ndi mphete ya benzene ndipo umakhala ndi kukana kwa dzimbiri.

3. Pankhani yokonda zachilengedwe:

Polypropylene ndi thermoplastic material yomwe siiwonongeka mosavuta komanso imawononga chilengedwe. Ulusi wa polyester ukhoza kuwonongedwa ndi tizilombo toyambitsa matenda ndipo sudzawononga chilengedwe.

Magawo osiyanasiyana ogwiritsira ntchito

Chifukwa cha kukana kwake kwa asidi ndi alkali komanso kuyamwa kochepa kwa chinyezi, ulusi wa polypropylene umagwiritsidwa ntchito kwambiri m'magawo monga zamankhwala ndi zamankhwala, zinthu zakunja, kusefera kwa mafakitale, ndi zida zoteteza. Mwachitsanzo, masks azachipatala, mikanjo ya opaleshoni, ndi zovala zotchinjiriza zotayidwa zimapangidwa pogwiritsa ntchito zida za polypropylene; Mahema, zovala zosalowa madzi, ndi zinthu zina zakunja nthawi zambiri zimapangidwa ndi ulusi wa polypropylene.

Ulusi wa poliyesitala umagwiritsidwa ntchito kwambiri m'magawo monga nsalu, zovala, nsalu za mafakitale, ndi mapulasitiki olimbitsa magalasi. Mwachitsanzo, zinthu zopangidwa ndi polyester fiber zitha kugwiritsidwa ntchito kupanga nsalu monga zovala, zovala zamkati, zofunda, makatani, ndi zofunda; Kuphatikiza apo, ulusi wa polyester umagwiritsidwanso ntchito kwambiri popanga zinthu zamapulasitiki zolimbitsa magalasi.

Mapeto

Mwachidule, ngakhale ulusi wa polypropylene ndi polyester uli ndi mawonekedwe ofananirako ndi mawonekedwe ake, pali kusiyana kwakukulu kwa mfundo zopangira, mawonekedwe a katundu, ndi magawo ogwiritsira ntchito, ndipo zida zoyenera za ulusi ziyenera kusankhidwa malinga ndi zosowa zenizeni.
