Zipangizozi zakwera kwambiri. Kodi matewera, zopukutira m'manja mwaukhondo ndi zopukutira madzi sizingakwezere mtengo?

Chifukwa cha zifukwa zosiyanasiyana, makampani opanga mankhwala akwera kwambiri, ndipo mitengo yazinthu zambiri zopangira mankhwala yakwera. Makampani opanga zinthu zaukhondo akadali ndi vuto chaka chino ndipo amakhudzidwa mwachindunji.

Ogulitsa ambiri pazida zopangira ndi zothandizira (kuphatikiza ma polima, spandex, nsalu zosaluka, ndi zina zambiri) m'makampani aukhondo alengeza zakukwera kwamitengo. Chifukwa chachikulu chakuchulukirachi ndi kuchepa kwa zinthu zopangira kumtunda kapena kuwonjezeka kwamitengo. Ena ananenanso kuti asanapereke lamulo Ayenera kukambirananso.

Anthu ambiri aganiza: Mitengo yakumtunda yakwera, kodi kalata yowonjezerapo mitengo kuchokera kwa wopanga zotsirayo itsalira kwambiri?

Pali chowonadi china pamalingaliro awa. Ganizirani za kapangidwe kake ndi zopangira matewera, zopukutira ukhondo, ndi zopukutira zonyowa.

Zopukutira pamadzi ndizovala zopanda nsalu, pomwe matewera ndi zopukutira ukhondo zimakhala ndi zinthu zitatu zazikuluzikulu: wosanjikiza, wosungunuka, ndi wosanjikiza pansi. Nyumba zazikuluzikuluzi zimaphatikizira zinthu zina zopangira mankhwala.

1. wosanjikiza pamwamba: osaluka nsalu kuwonjezeka mtengo

Nsalu zosaluka sizimangokhala matewera apamwamba komanso zopukutira mwaukhondo, komanso zinthu zazikulu zopukutira konyowa. Nsalu zopanda nsalu zomwe zimagwiritsidwa ntchito popanga zinthu zaukhondo zimapangidwa ndi ulusi wopangira polyester, polyamide, polytetrafluoroethylene, polypropylene, kaboni fiber, ndi fiber fiber. Zimanenedwa kuti zinthu zamankhwala izi zikukweranso mtengo, chifukwa chake mtengo wa nsalu zosaluka uzikwiradi ndi kumtunda kwake, ndipo pachifukwa chomwechi, zinthu zomalizidwa zaukhondo zitha kukweranso.

2. Kutenga kosanjikiza: mtengo wazinthu zoyamwa SAP ukuwonjezeka

SAP ndiye chinthu chachikulu chopangira matewera oyamwa ndi zopukutira ukhondo. Utomoni wolowetsa madzi wa Macromolecular ndi polima wokhala ndi zinthu zoyamwa madzi zomwe zimasungunulidwa ndi ma monomers a hydrophilic. Chofala kwambiri komanso chotchipa kwambiri chotchedwa monomer ndi acrylic acid, ndipo propylene imachokera pakulimbana kwa mafuta. Mtengo wamafuta wakwera, ndipo mtengo wa acrylic acid Kutsatira kukwera, SAP izikwera mwachilengedwe.

3. Pansi pazitsulo: kuwonjezeka kwamitengo ya polyethylene yopangira

Mzere wapansi wa matewera ndi zopukutira zaukhondo ndi kanema wophatikizidwa, wopangidwa ndi kanema wapansi wopumira komanso nsalu yopanda nsalu. Zimanenedwa kuti kanema wopumira pansi ndi kanema wapulasitiki wopangidwa kuchokera ku polyethylene. (PE, imodzi mwamagawo akuluakulu apulasitiki, amapangidwa kuchokera ku zinthu za polyethylene Polymer.) Ndipo ethylene, monga mankhwala omwe amagwiritsidwa ntchito kwambiri petrochemical, amagwiritsidwa ntchito kwambiri popanga pulasitiki ya polyethylene. Mafuta osakongola akuwonetsa kukwera, ndipo mtengo wa zingwe zopumira pogwiritsa ntchito polyethylene ngati zopangira zitha kukwera mtengo wa polyethylene ukukwera.

Kukwera kwamitengo yazida zopangira kungapangitse kuti mtengo wazopanga zomwe zatsirizidwa uwoneke. Pansi pavutoli, palibe zotsatira zoposa ziwiri:

Imodzi ndikuti opanga zinthu zomalizidwa amachepetsa kugula kwa zinthu zopangira kuti achepetse kupanikizika, komwe kumachepetsa mphamvu yopangira matewera;

Zina ndikuti opanga zinthu zomalizidwa amagawana kukakamiza kwa othandizira, ogulitsa ndi ogula.

Mulimonsemo, kuwonjezeka kwa mtengo kumapeto kwa malonda kukuwoneka kosapeweka.

Zachidziwikire, zomwe zili pamwambazi ndi lingaliro chabe. Anthu ena amaganiza kuti kukwera kwamitengo kumeneku sikukhazikika, ndipo osachiritsika akadali ndi zowerengera zothandizira, ndipo kukwera mtengo kwa zinthu zomalizidwa sikungabwere. Pakadali pano, palibe opanga zotsirizira omwe apereka zidziwitso zakukweza mitengo.
