Maramara Polyester Tae-Cationic Āhua-Paikore

HuaKōeWhakamāramatanga

Ka hangaia ngā maramara polyester cationic haurua-pōuri mā te whakarerekētanga copolymerization me te whakaurunga o te monomer tuatoru i te wā o te polymerization o te polyester tikanga. Mā te whakauru i ngā rōpū sulfonate motuhake hei pae tae i runga i te mekameka ngota, ka taea te tae i te polyester, he uaua ki te tae i ngā wā o mua, ki ngā tae cationic i raro i ngā āhuatanga hauhautanga (ECDP) me ngā āhuatanga pēhanga teitei (CDP).

Ngā Āhuatanga Matua o te Hua

1. He pai te mahi tae

He tino hiahia ki ngā tae cationic, ka taea te tae mā te kohua hau (tohu ECDP) te tae pēhanga teitei rānei i te pāmahana teitei (tohu CDP). He nui te whakamahinga o te tae, he whānui te whānuitanga o ngā tae, he kanapa ngā atarangi, ā, he pai te pumau o te tae.

2. Te Whakarerekētanga Tinana Taurite

He rite tonu te ātete wera, te ātete waikura, me ngā āhuatanga hangarau ki te PET tuku iho. Mā te whakarerekētanga anō me te wāhanga tuawhā ka taea te whakatutuki i te ngawari o te pa o te muka me te whakapai ake i te mahi ārai-piri.

3. Ngā Pānga Whakaranu Ahurei

Ina whakaranua ki ngā muka PET tuku iho, ki ngā muka cellulosic rānei (hei tauira, te miro, te viscose), ka taea e te tae kotahi-kaukau te whakaputa i ngā pānga motuhake pērā i te tae mā, ngā pānga tae-rua rerekē, ngā pānga tae-maha rānei.

4. He Kaha te Mahi

He pai mō te whakaranu ki ngā momo muka mahi matua pērā i te ātete mura, te ārai huakita, te tango makuku, me te momo maroke tere, e āhei ai te whakawhanake i ngā muka rerekē, mahi me ngā muka kore-muka.

Ngā Maramara Polyester Tae Cationic Ātete-Mumura

Whakamāramatanga Matua o te Hua

He maramara polyester kua whakarerekētia te mahi-teitei i hangaia mā te whakarerekētanga copolymerization, e whakauru ana i ngā wāhanga pae tae cationic me ngā wāhanga ārai mura e hangai ana ki te phosphorus ki roto i te mekameka macromolecular polyester.

He mea tino whai hua tēnei ki te whakaoti i ngā raruraru o te polyester tuku iho—he uaua te tae, te hiahia kia tae i te pāmahana teitei me te pēhanga teitei, me te iti o te whānuitanga tae. Ka taea e te hua te tae kanapa me ngā tae cationic i raro i ngā tikanga kohua hau, me te pupuri tonu i ngā āhuatanga taketake o te polyester (PET) ki te taumata teitei.

I taua wā anō, ko tōna āhuatanga ā-roto mō te ātete ahi ka whakarite kia roa te mau o ngā muka me ngā papanga ki te ātete ahi. He whānuitia te whakamahinga i roto i ngā mahi kakahu, whakapaipai me ngā mahi ahumahi motuhake, me ngā whakaritenga tino kaha mō te kanapa o te tae, te āhua o te ringaringa me te mahi haumaru.

Ngā Painga Matua o te Hua

1. Te ātete mura tūturu, te haumaru, te roa me te hoa-taiao

He rerekē tēnei i ngā pūnaha ātete-mutunga whakaranu, engari ka whakamahia te hangarau copolymerization, arā, ka horapa ōrite ngā wāhanga ātete-mutunga i roto i te hanganga matua o te polyester, ka whakarato i ngā āhuatanga tineia-ake mō te wā roa, ā, ka ārai pai hoki i te horapa o te mura. Kāore he halogen i roto i te hua, e tutuki ana i ngā ture taiao a te EU pērā i te RoHS me te REACH, he iti te tukunga paowa me te kore e tukuna he hau paitini i te wā e tahuna ana, ā, he haumaru, he pai hoki mō te taiao.

2. He tino pai te tae me te tae kanapa me te tae tonu

Ka taea te tae i te pāmahana koropupū o te āhuarangi (100°C) me te kore he kaikawe, e whakaiti ana i te penapena pūngao me te whakapaunga. He kanapa ngā tae o ngā papanga tae, he whānui ngā tae, ā, he pakari te tae, e tutuki ai ngā whakaritenga hoahoa o ngā hua whatu pouri me ngā hua whatu maha-tae.

3. Ngā āhuatanga ā-tinana me ngā āhuatanga ā-mīhini pai me te āheinga hurihuri

He pakari ā-roto pumau, he pai hoki te ira rewa, ā, he tino pai te pumau o te wera me te āhua hurihuri o te hua. He paku pakari, he roa hoki ngā muka kua hangaia, ā, he ngawari hoki te āhua o te ringaringa, e whakakore ana i ngā raruraru pēnei i te pakari me te whakapūpū e kitea ana i roto i ngā muka ātete-mura noa.
