Matabwa achilengedwe ndi zitsulo zakhala zofunikira zomangira kwa anthu kwazaka masauzande ambiri.
Zitsulo zonsezi ndi pulasitiki zimakhala ndi katundu yemwe amayenereradi mafakitale komanso malonda. Gwiritsani ntchito.
Pazolinga zina, nkhuni zachilengedwe zimatha kupikisana ndi zitsulo ndi ma pulasitiki.Mutor.Kuvutoli Posachedwa?
Kapangidwe kakang'ono ka nkhuni kumakhala pafupifupi 50% cellulose, polymer wachilengedwe wokhala ndi mphamvu zambiri. Hamu Ndipo amagwira ntchito zothandiza panthaka yamoyo.bwefu chifukwa cha cholinga cha anthu pakupanga matabwa ndikumanga zingwe zake zolimba limodzi, Lignin adakhala cholepheretsa.
Pa phunziroli, matabwa achilengedwe adapangidwa kukhala nkhuni zouma (HW) m'masitepe anayi.First, nkhuni zimasandutsa zojambulazo kwa nthawi yayitali. Fibers.Next, nkhuni zimayang'aniridwa pa 105 ° C (221 ° F) kwa maola ena kuti athetse mafuta a mchere kwa maola 48 kuti apangitse mankhwalawa.
Katswiri wina wamakina a zinthu zopangidwa ndi mawonekedwe, omwe ndi njira yothetsera vutoli pomwe amalima, owuma kwambiri kuposa golide, ndi gawo losavuta: adakanikizidwa mu mayeso okhala ndi mphamvu inayake. Poyankhula mokulira, chokulirapo dzenje la mpira limagunda, chofewa.
Matanda ambiri achilengedwe amatha kuyamwa madzi. Tsopano amatha kukulitsa nkhuni ndipo pamapeto pake olemba amagwiritsa ntchito michere yam'madzi yam'madzi Hydrophilic ("wokonda zamadzi"), mbali inayo, imafalitsa madzi osanja (ndipo pambuyo pake, michere imangochulukitsa kwambiri imachulukitsa mphamvu ya HW, komanso imalepheretsa nkhuni kuti zisatenge chinyezi.
M'mayesero ena opatsirana, ma HW adakonzera bwino kwambiri kuposa mipeni ya a HW. Mbali yomweyo ndi mbali yopanda chitsulo, ndipo mpeni wa steak ungagwire ntchito bwino kwambiri.
Nanga misomali?
Ali ndi misomali yabwino munjira zinanso.
Palibe kukayika kuti wolemba adapanga njira yopangira nkhuni kuposa zopangira zachilengedwe.
