He aha te Kaiwhakaū Mārama-944 CAS 70624-18-9?

He pai te ātete o te whakapūmau rama UV-944 ki te tango, he tino pai mō ngā hua angiangi, pērā i ngā muka me ngā kiriata; Ka taea hoki e ia te whakapai ake i te ātete tawhito o te hāora wera o te rauemi. He mā ki te kōwhai mārama ngā matūriki, he paura rānei o te whakapūmau rama HS-944, he ira rewa 100-135°C, he taumaha ngota 2000-3100, he tino hototahi, he ātete tango me te iti o te hurihuri. Nā te mea he whakapūmau papatipu ngota whanaunga teitei te UV-944, ā, he nui noa te methylate kei roto i te ngota, he pumau ina rongoatia ki te hāora wera.

Tono

Ko te Light Stabilizer-944 e whakamahia ana i roto i te kiriata polyethylene iti te matotoru, te muka polypropylene, te rīpene polypropylene, te kiriata EVA, te ABS, te polystyrene me ngā takai kai. Ko te Light stabilizer HS-944 nō te hindered amine light stabilizer.

Ā mātou painga

1. He pānga pai rawa atu mō te pumau o te mārama: Ka taea e te UV-944 te tiaki i ngā rauemi pūmua mai i te pānga o te mārama ultraviolet me te pirau whakaahua me te pirau wera i puta mai i te koroheketanga wera roa. Ko tōna pānga pumau mārama he nui ake i ngā mea mimiti ultraviolet me ngā mea pumau kei roto he nikara, inā koa i roto i ngā pūnaha tae e kitea nuitia ana te pānga.

2. He pai te hototahitanga me te mahi tukatuka: He rauemi maramara kōwhai mārama, he iti te piki me te heke. He pai te hototahitanga ki ngā momo rauemi polymer pēnei i te PP, LDPE, HDPE, me te PVC. Ka taea te whakamarara ngāwari ki roto i te hanganga polymer me te kore e pā ki te māramatanga me te tae o te kapia, ā, he tino pai te mahi tukatuka.

3. He whānui te whānuitanga o te whakamahinga, ā, he haumaru, he pono hoki: He pai te UV-944 mō ngā momo rauemi pēnei i ngā kiriata, ngā muka, me ngā hua matotoru, ā, ka taea te whakamahi mō ngā polymer maha tae atu ki ngā polyolefin, ngā polyurethane, me ngā polyamide. I taua wā, kua whakaaetia e te FDA, ā, ka taea te whakamahi i roto i ngā tono pa ki te kai, e whakaatu ana i tētahi taumata haumaru.
