1. zosiyanasiyana
Mitundu ya ulusi wa polypropylene imaphatikizapo ulusi (kuphatikiza ulusi wosasinthika ndi ulusi wopunduka wochuluka), ulusi wokhazikika, ulusi wa mane, ulusi wogawanika, ulusi wocheperako, ulusi wopangidwa ndi mbiri, ulusi wosiyanasiyana komanso nsalu zosalukidwa.Amagwiritsidwa ntchito kwambiri popanga makapeti (kuphatikiza nsalu zoyambira pa carpet ndi suede), nsalu zodzikongoletsera, nsalu zapanyumba, zingwe zosiyanasiyana, mikwingwirima, maukonde osodza, zomangira mafuta, zida zomangira nyumba, zida zonyamula katundu ndi nsalu zamakampani, monga nsalu zosefera ndi thumba nsalu.Kuphatikiza apo, amagwiritsidwa ntchito kwambiri pazovala.Zitha kuphatikizidwa ndi ulusi wosiyanasiyana kupanga mitundu yosiyanasiyana ya nsalu zosakanikirana.Pambuyo kuluka, zikhoza kupangidwa kukhala malaya, zovala zakunja, masewera, masokosi, ndi zina zotero.
2. Mankhwala katundu
Dzina la sayansi la polypropylene fiber ndiloti limasungunuka pafupi ndi lawi lamoto, limayaka, limayaka pang'onopang'ono kutali ndi moto ndipo limatulutsa utsi wakuda.Kumtunda kwa lawi lamoto ndi lachikasu ndipo kumapeto kwa buluu ndi buluu, kumatulutsa fungo la mafuta.Akawotcha, phulusalo ndi lolimba, lozungulira komanso lachikasu labulauni, lomwe silimalimba likamapindidwa ndi dzanja.
3. Zinthu zakuthupi
The longitudinal ndege ya morphology polypropylene ulusi ndi lathyathyathya ndi yosalala, ndi gawo mtanda ndi kuzungulira.
Ubwino waukulu wa ulusi wa polypropylene fiber ndi mawonekedwe ake opepuka, kachulukidwe kake ndi 0.91g / cm3 yokha, yomwe ndi mitundu yopepuka yamitundu yodziwika bwino yamafuta, kotero kuti ulusi womwewo wolemera wa polypropylene ukhoza kupeza malo ophimba kwambiri kuposa ulusi wina.
Chingwe cholimba cha polypropylene chimakhala ndi mphamvu zambiri, kutalika kwakukulu, modulus yayikulu komanso kulimba kwambiri.Chifukwa chake, ulusi wa polypropylene uli ndi kukana kwabwino kovala.Kuonjezera apo, mphamvu yonyowa ya polypropylene imakhala yofanana ndi mphamvu youma, choncho ndi chinthu choyenera kupanga maukonde ndi zingwe.
Ndipo ali ndi kuwala kwa hygroscopicity ndi dyeability, kusunga kutentha kwabwino;Pafupifupi palibe mayamwidwe chinyezi, koma amphamvu mayamwidwe mphamvu, zoonekeratu chinyezi mayamwidwe ndi thukuta;Ulusi wa polypropylene umakhala ndi mayamwidwe ochepa, pafupifupi samayamwa chinyezi, ndipo chinyezi chomwe chimabwereranso mumlengalenga chimakhala pafupi ndi ziro.Komabe, imatha kuyamwa mpweya wamadzi kudzera m'ma capillaries munsalu, koma ilibe mphamvu iliyonse yoyamwa.Ulusi wa polypropylene umakhala ndi utoto wosawoneka bwino komanso chromatography yosakwanira, koma ukhoza kupangidwa ndi njira yopangira utoto wamitundu.
Acid-ndi alkali-resistant polypropylene imakhala ndi kukana kwa dzimbiri kwamankhwala.Kupatula anaikira nitric asidi ndi anaikira caustic koloko, polypropylene ali bwino kukana asidi ndi zamchere, choncho ndi oyenera kugwiritsidwa ntchito ngati fyuluta zakuthupi ndi ma CD zinthu.
Kuthamanga kwa kuwala, etc. Polypropylene imakhala ndi kuwala kosasunthika, kusasunthika kwa kutentha, kukalamba kosavuta komanso kusagwirizana ndi kusita.Komabe, ntchito yoletsa kukalamba imatha kupitilizidwa powonjezera anti-aging agent pakupota.Kuonjezera apo, polypropylene imakhala ndi magetsi abwino, koma ndiyosavuta kupanga magetsi osasunthika panthawi yokonza.Polypropylene imakhala ndi kutsika kwamafuta otsika komanso kutsekemera kwabwino kwamafuta.
Mphamvu ya ulusi wamphamvu kwambiri wa polypropylene zotanuka ndi yachiwiri kwa nayiloni, koma mtengo wake ndi 1/3 yokha ya nayiloni.Nsalu yopangidwa imakhala ndi kukula kokhazikika, kukana bwino kwa abrasion ndi elasticity, komanso kukhazikika kwa mankhwala.Komabe, chifukwa cha kusasunthika kwake kwa kutentha, kukana kutsekemera komanso kukalamba kosavuta komanso kuwonongeka kwamphamvu, anti-aging agents nthawi zambiri amawonjezeredwa ku polypropylene.
4. Ntchito
Kugwiritsiridwa ntchito kwapachiweniweni: Ikhoza kukulungidwa koyera kapena kusakanikirana ndi ubweya, thonje kapena viscose kupanga mitundu yonse ya zovala.Atha kugwiritsidwa ntchito kuluka mitundu yonse ya knitwear monga masokosi, magolovesi, knitwear, mathalauza oluka, nsalu mbale, udzu ukonde nsalu, quilt, kutentha stuffing, thewera chonyowa, etc.
Ntchito zamafakitale: makapeti, maukonde ophera nsomba, zinsalu, ma hoses, kulimbikitsa konkire, nsalu za mafakitale, nsalu zopanda nsalu, ndi zina zotero monga makapeti, nsalu zosefera za mafakitale, zingwe, maukonde ophera nsomba, zipangizo zomangira nyumba, mabulangete otsekemera mafuta ndi nsalu zokongoletsera, etc. Komanso, polypropylene filimu CHIKWANGWANI angagwiritsidwe ntchito ngati ma CD zakuthupi.
5. Kapangidwe
Ulusi wa polypropylene ulibe magulu a mankhwala omwe angaphatikizepo ndi utoto mu kapangidwe kake ka macromolecular, kotero ndizovuta kuunika.Nthawi zambiri, kukonzekera kwa pigment ndi polypropylene polima zimasakanizidwa mofanana mu screw extruder ndi njira yosungunula, ndipo ulusi wachikuda womwe umapezedwa ndi kusungunula umakhala wothamanga kwambiri.Njira ina ndi copolymerization kapena kumezanitsa copolymerization ndi acrylic acid, acrylonitrile, vinilu pyridine, etc., kotero kuti magulu polar amene akhoza pamodzi ndi utoto anayambitsa polima macromolecules, ndiyeno utoto mwachindunji ndi njira ochiritsira.Popanga ulusi wa polypropylene, nthawi zambiri pamafunika kuwonjezera zowonjezera zosiyanasiyana kuti muzitha kutulutsa utoto, kukana kuwala komanso kukana moto.
