Malangizo a Mayankho
Kuthamanga kwabwino kwambiri kwa kuwala
Malangizo abwino kwambiri a chisankho cha mankhwala a syntan
Nthawi zonse pamakhala zinthu zakale zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi iliyonse tikaganizira za izo. Monga nsapato zoyera zachikopa zomwe zili mu kabati yanu ya nsapato.
Komabe, nthawi zina zimakuvutitsani kukumbukira kuti pakapita nthawi, nsapato zomwe mumakonda sizidzakhalanso zoyera komanso zonyezimira, ndipo pang'onopang'ono zimakhala zakale komanso zachikasu.
Tsopano tiyeni tidziwe chomwe chili kumbuyo kwa chikopa choyera——
Mu 1911 AD Dr. Stiasny adapanga tannin yatsopano yopangidwa yomwe ingalowe m'malo mwa tannin ya masamba. Poyerekeza ndi tannin ya masamba, tannin yopangidwa ndi yophweka kupanga, ili ndi mphamvu yabwino yopaka utoto, mtundu wopepuka komanso yolowera bwino. Chifukwa chake yakhala yofunika kwambiri mumakampani opanga utoto pazaka zana zapitazi. Muukadaulo wamakono wopaka utoto, mtundu uwu wa tannin yopangidwa umagwiritsidwa ntchito pafupifupi pazinthu zonse.
Chifukwa cha kapangidwe kake kosiyana ndi kagwiritsidwe ntchito kake, nthawi zambiri amatchedwa tannin yopangidwa, tannin ya phenolic, tannin ya sulfonic, tannin yofalikira, ndi zina zotero. Chofala cha ma tannin awa ndichakuti monomer yawo nthawi zambiri imakhala ndi kapangidwe ka mankhwala a phenolic.
Komabe, pamene kapangidwe ka phenolic kakukhudzidwa ndi kuwala kwa dzuwa, makamaka ndi kuwala kwa UV, kamapanga kapangidwe ka mtundu komwe kamasintha chikopa kukhala chachikasu: Kapangidwe ka phenol kamasinthidwa mosavuta kukhala kapangidwe ka quinone kapena p-quinone kopanga utoto, ndichifukwa chake kupepuka kwake kumakhala kochepa.
Poyerekeza ndi tannin yopangidwa, polymer tannin agent ndi amino resin tanning agent ali ndi mphamvu yabwino yoletsa chikasu, motero pochiza chikopa, tannin yopangidwa yakhala njira yofooka yoletsa chikasu.
Pofuna kuthetsa vutoli, gulu la kafukufuku ndi chitukuko la Decision linakonza bwino kapangidwe ka phenolic kudzera mu kuganiza ndi kapangidwe katsopano, ndipo potsiriza linapanga tannin yatsopano yopangidwa yokhala ndi kuwala kofulumira kwambiri:
DESOATEN SPS
Syntan yokhala ndi kufulumira kwa kuwala kwabwino kwambiri
Poyerekeza ndi ma syntans achikhalidwe, mphamvu ya DESOATEN SPS yoletsa chikasu yapita patsogolo kwambiri——
Ngakhale poyerekeza ndi mankhwala opangidwa ndi polymer tanning ndi amino resin tanning agent, DESOATEN SPS imatha kuwaposa m'mbali zina.
Pogwiritsa ntchito DESOATEN SPS ngati tannin yopangira, kuphatikiza ndi zinthu zina zopaka utoto ndi mafuta, kupanga zikopa zonse ndi zikopa zoyera zomwe zimakhala zosavuta kuziona kungathe kuchitika.
Choncho pitirizani kuvala nsapato zanu zoyera zachikopa zomwe mumakonda momwe mungafunire, pitani kugombe ndikusamba padzuwa, palibe chomwe chingakulepheretseni tsopano!
Chitukuko chokhazikika chakhala gawo lofunika kwambiri mumakampani opanga zikopa, njira yopita ku chitukuko chokhazikika ndi yayitali komanso yodzaza ndi zovuta.
Monga kampani yodalirika, tidzagwira ntchito imeneyi ngati udindo wathu ndipo tidzagwira ntchito mosalekeza komanso molimba mtima kuti tikwaniritse cholinga chathu.
Onani zambiri
