Ngā Taunakitanga Whakatau
He tino pakari te mārama
Te taunakitanga tino pai a te whakataunga mō te hua syntan
He maha tonu ngā mea tawhito e kitea ana e tātou i roto i ō tātou ao e menemene ai tātou i ia wā ka mahara tātou ki aua mea. Pērā i ngā pūtu hiako ma tino whakamarie i roto i tō kāpata hu.
Heoi, i ētahi wā ka pāwera koe i te mahara ka roa te wā, ka kore ō pūtu tino pai e mā, e kanapa, ā, ka tawhito haere, ka kōwhai haere.
Nā, kia kitea te take o te kōwhaitanga o te hiako mā—
I te tau 1911 AD, i whakawhanakehia e Tākuta Stiasny tētahi tannin hanga hou hei whakakapi i ngā tannin huawhenua. Ki te whakatauritea ki ngā tannin huawhenua, he ngāwari te hanga tannin hanga, he pai te āhua o te kiri parauri, he mārama te tae, ā, he pai te uru ki roto. Nō reira, kua nohoia e ia tētahi tūranga nui i roto i te umanga kiri parauri i roto i ngā rau tau o te whanaketanga. I roto i te hangarau kiri parauri hou, e whakamahia ana tēnei momo tannin hanga i roto i te nuinga o ngā tuhinga.
Nā te rerekētanga o te hanganga me te whakamahinga, ka kiia rātou he tannin hangai, he tannin phenolic, he tannin sulfonic, he tannin disperse, me ētahi atu. Ko te āhua ōrite o ēnei tannin ko te hanganga matū phenolic o te monomer.
Heoi, ina pāngia te hanganga phenolic e te rā, inā koa ki ngā hihi UV, ka hangaia he hanganga whakaputa tae ka kōwhai te hiako: Ka ngāwari te waikura o te hanganga phenolic ki te hanganga whakaputa tae quinone, p-quinone rānei, koia te take he ngoikore tōna pumau ki te mārama.
Ki te whakatauritea ki te tannin hangai, he pai ake te āhuatanga ārai-kōwhai o te kaihoko tannin polymer me te kaihoko tannin amino resin, nō reira, kua noho ngā tannin hangai hei hononga ngoikore mō te mahi ārai-kōwhai i roto i te maimoatanga hiako.
Hei whakaoti i tēnei raruraru, i arotau te tīma R&D a Decision i te hanganga phenolic mā te whakaaro auaha me te hoahoa, ā, i te mutunga ka whakawhanakehia he tannin hanga hou me te ātete ki te māramatanga tino pai:
TE WHAKAMAHI I NGĀ SPS
Syntan me te pumau mārama tino pai
Ki te whakataurite ki ngā syntans tuku iho, kua nui ake te kaha o te DESOATEN SPS ki te ārai i te kōwhai——
Ahakoa te whakataurite ki te hinu whakahinuhinu polymer me te hinu whakahinuhinu amino resin tuku iho, ka taea e DESOATEN SPS te wikitoria i a rātou i ētahi āhuatanga.
Mā te whakamahi i te DESOATEN SPS hei tannin hangai matua, me ētahi atu kai tanning me ngā fatliquors, ka taea te whakatutuki i te hanga hiako whānui me te hiako mā me te tino pakari ki te mārama.
Nō reira, haere tonu, kākahuria ō pūtu hiako ma tino pai ki a koe, haere ki te takutai moana ka kaukau i te rā, kāore he mea hei aukati i a koe inaianei!
Kua tino whai wāhi te whanaketanga tauwhiro ki te umanga hiako, engari he roa tonu te ara ki te whanaketanga tauwhiro, ā, he maha ngā wero.
Hei umanga whai kawenga, ka amohia e mātou tēnei hei kawenga mā mātou, ā, ka mahi tonu mātou me te kore e taea te whakakorekore ki te whakatutuki i te whāinga whakamutunga.
