Kuvumbulutsa chozizwitsa cha kupukuta khungu: Ulendo wosangalatsa kudzera mu zochita za mankhwala

Chikopa sichimangogwiritsidwa ntchito ngati mafashoni okha, komanso chimachokera ku njira yabwino kwambiri yopangira utoto. Pankhani ya zochita za mankhwala a chikopa, njira imodzi yofunika kwambiri imaonekera -kubwezeretsanso utoto Tiyeni tiyambe ulendo wosangalatsa wopeza zinsinsi zotetezera khungu, njira yofunika kwambiri popanga chikopa, ndikuwona dziko lodabwitsa la mankhwala a chikopa.

1. Sayansi yokhudza kupukuta khungu: Kupukuta khungu ndi njira yosinthira zikopa za nyama zosaphika kukhala zinthu zolimba komanso zosinthasintha. Njirayi imaphatikizapo machitidwe osiyanasiyana a mankhwala omwe amalimbitsa ulusi wa collagen mkati mwa chikopa ndikuchiletsa kuti chisawole. Mankhwala apadera otchedwa retanning agents amachita gawo lofunikira kwambiri pakupukuta khungu.

2. Dziwani kubwezeretsedwa kwa mphamvu ndizinthu zotetezera khungu: Zinthu zotetezera khungu ku dzuwa ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga khungu la chikopa. Zinthu zimenezi zimathandiza kuti khungu likhale lofewa, lolimba komanso lolimba. Zimathandizanso kuti khungu likhale lolimba komanso lolimba.

3. Pali mitundu yambiri yazinthu zotetezera khungu: Zinthu zotetezera kutentha zimakhala ndi mitundu yosiyanasiyana, iliyonse ili ndi ntchito yakeyake. Zodzaza, monga kaolin, zimagwiritsidwa ntchito kudzaza malo omwe ali mkati mwa kapangidwe ka chikopa, zomwe zimapangitsa kuti zinthuzo zikhale zosalala komanso zooneka bwino. Ma resin, monga ma acrylics, amathandizira kugwirizanitsa ulusi pamodzi kuti ukhale wolimba. Mafuta, monga mafuta opangidwa ndi achilengedwe, amapaka chikopa mafuta ndikuwonjezera kusinthasintha kwake. Kuphatikiza apo, mankhwala ochokera ku sulfure amagwiritsidwa ntchito pothandizira polymerization ya mankhwala otetezera kutentha, motero amawonjezera kulimba.

4. Kuganizira za chilengedwe: M'zaka zaposachedwapa, makampani opanga zikopa asintha chidwi chawo pakupanga zinthu zokhazikika komanso zosawononga chilengedwe. Chifukwa cha kupita patsogolo kwa ukadaulo wa zikopa, zinthu zoteteza khungu la chilengedwe monga zotumphukira ku zomera ndi zinthu za biomimetic zatchuka chifukwa cha kuchepa kwa mphamvu zawo zachilengedwe. Zinthu zimenezi zimachepetsa kutulutsa zinthu zoopsa m'chilengedwe, zomwe zimapangitsa kuti khungu la chikopa likhale lolimba.

5. Tsatirani miyezo ya khalidwe: Zogulitsa za chikopa zimayesedwa bwino kwambiri ndipo zimakwaniritsa miyezo yapadziko lonse lapansi. Kugwiritsa ntchito mosamala zinthu zotetezera khungu kumatsimikizira kuti chinthu chomaliza chikwaniritsa zofunikira monga kusinthasintha kwa mtundu, kufewa komanso kukana kukanda kapena kung'ambika. Njira zapamwamba zowunikira, kuphatikizapo kusanthula ma electron microscopy ndi kusanthula kwa spectroscopic, zimathandiza kutsimikizira magawo abwino awa. Pomaliza: Dziko la kuyeretsa khungu ndi kuyeretsa khungu ndi kuphatikiza kosangalatsa kwa luso la sayansi, zaluso ndi chidziwitso cha chilengedwe.

Pamene makampani opanga zikopa akupitilizabe kusintha, kupita patsogolo kwa ukadaulo ndi mankhwala opangira zinthu kukulonjeza kupereka zinthu zapamwamba komanso zokhazikika zachikopa. Kumvetsetsa zovuta za retanning ndi momwe mankhwala amagwirira ntchito sikuti kudzangowonjezera kuyamikira kwathu zinthu zachikopa komanso kudzawulula kuthekera kwakukulu kwa makampani opanga mankhwala a chikopa. Mwa kufufuza dziko la mankhwala a chikopa, tikuwulula zinsinsi zopangira zikopa zokongola zomwe zimakhala zolimba, zosinthasintha komanso zokongola, pamene tikugwirizana ndi kufunikira kowonjezereka kwa zinthu zokhazikika.
