Kuwala kwakukulu
Malangizo Oyenera Abwino
Nthawi zonse pamakhala zidutswa zina zazing'ono zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi iliyonse yomwe timawaganizira. Monga nsapato zapamwamba kwambiri zoyera zazingwe mu nduna yanu ya nsapato.
Komabe, kumakusangalatsani nthawi zina kukumbukira kuti pakapita nthawi, nsapato zanu zomwe mumakonda sizikhala zoyera komanso zonyezimira, ndipo pang'onopang'ono ikadakalamba ndi chikasu pang'onopang'ono.
Tsopano tiyeni tipeze chomwe chiri kumbuyo kwa chikasu choyera
Mu 1911 AD Dr. Stoisny yapanga buku lopanda buku lomwe limatha kusintha masamba tanin. Poyerekeza ndi masamba annin, zopanga tannin ndizosavuta kubala, zimakhala ndi katundu wonyezimira, mtundu wopepuka komanso kulowa bwino. Chifukwa chake yakhala ikukhala yofunika kwambiri pazambiri zokutira zaka zana zikuchitika. Mu ukadaulo wamakono wamakono, mtundu wopangidwa ndi tanin umagwiritsidwa ntchito pafupifupi nkhani zonse.
Chifukwa cha kapangidwe kake kake, kagwiritsidwe ntchito nthawi zambiri, zimatchedwa kuti snomen tanin, sulfonic tannin, yofatsa tannin, etc.
Komabe, kapangidwe ka phenoyic ikawonetsedwa ndi kuwala kwa dzuwa, makamaka kuwunika kwa UV, kumapangitsa kuti mawonekedwe a zikopa azikhala ndi zikopa: mawonekedwe a phenol amakhala oxidit kapena p-quinone kutembenuka kwamtunduwu kulibe wosauka.
Kuyerekezera tannin, polymer Tanin Mtumiki ndi amino restin wojambula ali ndi malo abwino oletsa chikopa, motero kuti zikopa zachikopa, zopangidwa ndi tanins zakhala zolumikizana ndi chikopa cha anti-chikopa.
Pofuna kuthana ndi vutoli, gulu la R & D lidangothamangitsa pazinthu zofananira ndi kapangidwe kake, ndipo pamapeto pake zidapanga tatin yatsopano yosalala kwambiri:
Osenda
Syntan ndi kuwala kowala bwino
Kuyerekezera ma syntans achikhalidwe, malo ochitira chikasu a ma sps ogwedezeka atulutsa dipa yofunika--
Ngakhale kuyerekezera ndi wothandizira wamba wa polymer ndi amino restin popewa, osungunuka amatha kuwachotsa mbali zina.
Pogwiritsa ntchito mabatani owonongera ngati tannin yayikulu, kuphatikiza ndi mankhwala ena opindika, kupanga mafuta ambiri, kupanga zikopa zoyera komanso chikopa choyera chomwe chimatha.
Chifukwa chake pitirirani ndikuvala nsapato zoyera zomwe mumakonda, pitani pagombe ndikusamba ndikuwunika kwa dzuwa, palibe chomwe chikanakulepheretsani tsopano!
Kukhazikika kosasunthika kwakhala gawo lofunikira kwambiri m'makampani achikopa, njira yokhazikika yokhazikika ndi yayitali komanso yovuta.
Monga bizinesi yodalirika tidzanyamula izi ngati udindo wathu ndikugwira ntchito molimbika komanso moyang'ana pansi.
