Nguva dzose kune zvimwe zvinhu zvechinyakare zvatinowana muhupenyu hwedu zvinoita kuti tinyemwerere pese patinozvifunga. Sezvakaita bhutsu chena dzeganda dzakanaka dziri mukabati reshangu dzako.
Zvisinei, dzimwe nguva zvinokunetsa kurangarira kuti nekufamba kwenguva, bhutsu dzako dzaunofarira hadzichave chena uye dzinopenya, uye dzinozopedzisira dzave dzekare uye dzeyero zvishoma nezvishoma.

Muna 1911 AD Dr. Stiasny vakagadzira tannin itsva yekugadzira inogona kutsiva tannin yemuriwo. Kana tichienzanisa ne tannin yemuriwo, tannin yekugadzira iri nyore kugadzira, ine hunhu hwakanaka hwekutsvukisa ganda, ruvara rwakajeka uye inopinza zvakanaka. Saka yave nechinzvimbo chakakosha muindasitiri yekutsvukisa ganda kwemakore zana ekuvandudzwa. Muhunyanzvi hwemazuva ano hwekutsvukisa ganda, rudzi urwu rwe tannin yekugadzira runoshandiswa muzvinhu zvinenge zvese.
Nekuda kwemaumbirwo awo akasiyana uye mashandisirwo awo, anowanzonzi synthetic tannin, phenolic tannin, sulfonic tannin, disperse tannin, nezvimwewo. Hunhu hwematannin aya ndehwekuti monomer yawo inowanzova ye phenolic chemical structure.
Zvisinei, kana chimiro chephenolic chikavhenekerwa nezuva, kunyanya nemwaranzi yeUV, chinogadzira chimiro chekuburitsa mavara chinoshandura ganda kuita yero: Chimiro chephenol chinogadziriswa nyore nyore kuita chimiro chekuburitsa mavara chequinone kana p-quinone, ndosaka kusakurumidza kwayo kushoma.
Zvichienzaniswa ne tannin yakagadzirwa, polymer tannin inoshandiswa pakugadzira ganda uye amino resin inoshandiswa pakugadzira ganda zvine hunhu huri nani hwekudzivirira yellowing, saka pakurapa ganda, tannin inoshandiswa pakugadzira yave nzira isina simba yekudzivirira yellowing.
Kuti vagadzirise dambudziko iri, timu yeDecision's R&D yakagadzirisa chimiro chephenolic kuburikidza nekufunga nekugadzira zvinhu zvitsva, uye pakupedzisira vakagadzira tannin itsva yekugadzira ine chiedza chakasimba:
DESOATEN SPS
Syntan ine kusimba kwechiedza kwakanaka
Zvichienzaniswa ne syntans dzechinyakare, hunhu hweDESOATEN SPS hunodzivirira yellowing hwatora danho rakakura——
Kunyangwe tichienzanisa nechinhu chinowanzo shandiswa pakugadzira ganda repolymer uye chinhu chinoshandiswa pakugadzira ganda reamino resin, DESOATEN SPS inokwanisa kuvakunda mune zvimwe zvinhu.
Nekushandisa DESOATEN SPS se tannin huru yekugadzira, pamwe chete nezvimwe zvinoshandiswa pakugadzira ganda uye mafuta, kugadzirwa kweganda rakajairika pamwe chete neganda jena rine kusimba kwakanyanya kwechiedza kunogona kuwanikwa.
Saka pfeka bhutsu dzeganda jena dzaunofarira sezvaunoda, enda kumahombekombe wonogeza muchiedza chezuva, hapana chinogona kukumisa izvozvi!
Budiriro inochengetedza nharaunda yave chikamu chakakosha muindasitiri yematehwe, nzira yekuenda kubudiriro inochengetedza nharaunda ichiri refu uye izere nematambudziko.
Sekambani ine mutoro, tichazvitakura sebasa redu uye ticharamba tichishanda nesimba kuti tisvike pachinangwa chedu chekupedzisira.
