Kaihanga Utu Pai Waikawa Oxalic CAS：144-62-7
Ko te waikawa oxalic he waikawa dicarboxylic kaha e kitea ana i roto i te maha o ngā tipu me ngā huawhenua, ko te tikanga he tote konupūmā, he tote pāhare pākawa rānei. Ko te waikawa oxalic anake te matū e honoa tika ana ngā rōpū carboxyl e rua; nā reira ko te waikawa oxalic tētahi o ngā waikawa waro kaha rawa atu. Kāore i rite ki ētahi atu waikawa carboxylic (haunga te waikawa formic), ka tere te waikura; nā reira he mea whai hua hei whakaiti i te whakaahua, te whakama, me te tango waituhi. Ko te waikawa oxalic te tikanga ka whakaritea mā te whakamahana i te konutai formate ki te konutai hauwai hei hanga i te konutai oxalate, ka hurihia hei konupūmā oxalate ka rongoatia ki te waikawa whanariki hei whiwhi i te waikawa oxalic kore utu.
He iti noa te kukū o te waikawa oxalic i roto i te nuinga o ngā tipu me ngā kai tipu, engari he nui te kukū o te pīnihi, te chard me te pīti hei whakararuraru i te mimiti o te konupūmā kei roto i ēnei tipu.
Ka puta i roto i te tinana mā te pākia o te waikawa glyoxylic, te waikawa ascorbic rānei. Kāore e pākia engari ka tukuna ki roto i te mimi. Ka whakamahia hei matū tātari me te matū whakaiti whānui. Ko te waikawa oxalic he acaricide tūturu e whakamahia ana hei rongoā mō ngā mite varroa i roto i ngā koroni kāore he uri, he kete, he kahui rānei. Ka whakamahia te waikawa oxalic kua mimitihia e ētahi kaitiaki pī hei patu pepeke ki te mite Varroa pirinoa. -
Kapia Xanthan Utu Pai a te Kaihanga, Taumata Ahumahi CAS：11138-66-2
Ko te kapia Xanthan, e mōhiotia ana ko Hanseonggum, he momo exopolysaccharide moroiti e hangaia ana e te Xanthomnas campestris me te warowaihā hei rauemi mata matua (pērā i te māngaro kānga) mā te hangarau whakapūtanga. He ahurei tōna rheology, he pai te wairewa i te wai, he pumau ki te wera me te turanga waikawa, ā, he pai te hototahi ki ngā momo tote. Hei matū whakamātotoru, hei matū whakatārewatanga, hei emulsifier, hei whakaū, ka taea te whakamahi whānui i roto i te kai, te hinu, te rongoā me ētahi atu ahumahi neke atu i te 20, koinei te tauine whakaputa nui rawa atu o te ao me te polysaccharide moroiti e whakamahia whānuitia ana.
He paura nekeneke te kapia Xanthan, he kōwhai mārama ki te mā, he paku haunga. Ka wairewa ki te wai matao me te wai wera, he otinga kūpapa, ātete ki te hukapapa me te rewa, kāore e wairewa ki te etanoru. Ka marara te wai, ka whakaemulsified hei kōroiti matotoru pumau.

Kaihanga Utu Pai DINP Taumata Ahumahi CAS：28553-12-0
Diisononyl phthalate (DINP)：He wai hinuhinu mārama tēnei hua, he kakara pakupaku. He mea hanga kirihou matua maha ngā āhuatanga, he tino pai ngā āhuatanga. Ka rewa tēnei hua i roto i te PVC, ā, e kore e taupatupatu ahakoa he nui te whakamahinga. He pai ake te whakakorikori, te hekenga me te kore paitini i te DOP (dioctyl phthalate), ka taea ai e te hua te ātete pai ki te mārama, te ātete ki te wera, te ātete ki te koroheketanga me ngā āhuatanga whakamahana hiko, ā, he pai ake te mahi whānui i te DOP. Nā te mea he pai te ātete wai me te ātete tango i ngā hua i hangaia e tēnei hua, he iti te paitini, he ātete ki te koroheketanga, he pai te mahi whakamahana hiko, nō reira he whānui te whakamahinga i roto i ngā kiriata taonga takaro, waea, taura.
Ki te whakaritea ki te DOP, he nui ake, he roa ake hoki te taumaha ngota ngota, nō reira he pai ake te mahi tawhito, te ātete ki te hekenga, te mahi ārai-hau, me te ātete pāmahana teitei ake. Nō reira, i raro i ngā āhuatanga ōrite, he kino ake te pānga kirihou o te DINP i te DOP. E whakaponohia whānuitia ana he pai ake te taiao o te DINP i te DOP.
He pai ake te DINP i te whakapai ake i ngā painga o te whakaputanga. I raro i ngā tikanga tukatuka whakaputanga noa, ka taea e te DINP te whakaiti i te matotoru rewa o te ranunga i te DOP, ka āwhina i te whakaiti i te pēhanga o te tauira putanga, te whakaiti i te kakahu miihini, te whakanui ake rānei i te hua (tae atu ki te 21%). Kāore he take ki te whakarerekē i te tauira hua me te tukanga whakaputa, kāore he haumi tāpiri, kāore he whakapaunga pūngao tāpiri, ā, ka pupuri i te kounga hua.
He wai hinuhinu te DINP, kāore e wairewa i roto i te wai. Ko te tikanga ka haria mā roto i ngā waka tāke, i ngā peere rino iti, i ngā oko kirihou motuhake rānei.
Ko tētahi o ngā rauemi mata matua o DINP -INA (INA), he ruarua noa iho ngā kamupene o te ao ka taea te whakaputa, pērā i a Exxon Mobil o te Hononga o Amerika, te kamupene toa o Tiamana, te Kamupene Concord o Hapani, me te kamupene o Āhia ki te Tonga i Taiwan. I tēnei wā, kāore he kamupene ā-rohe e whakaputa ana i te INA. Ko ngā kaihanga katoa e whakaputa ana i te DINP i Haina me ahu mai i ngā kawemai.
