Hoʻopili a me nā Crosslinkers no UV Pauka Pauka

ʻO ke ala kūpono loa no ka hoʻokumu ʻana i ka uhi ʻana ʻo ia ka hoʻohana ʻana i kahi mea hoʻopili nui a me kahi crosslinker. Hiki i ka cross¬linker ke hoʻomalu i ka nui o ka pūnaewele no ka uhi ʻana, ʻoiai ka mea hoʻopili e hoʻoholo i nā waiwai o ka uhi e like me ka discoloration, ke kūpaʻa o waho, nā waiwai mechanical, etc.

Eia kekahi, e alakaʻi kēia ala i kahi manaʻo homogenous i nā noi uhi pauka e like me ke ʻano e lawe mai ana i ke ʻano like me nā uhi thermosetting kahi e hoʻohana ʻia ai nā crosslinkers e like me TGIC a me hydroxyl amides. Pono ka crosslinker e hōʻike i nā waiwai kikoʻī no ka noi i manaʻo ʻia: kaumaha molekala; hana kiʻekiʻe; a me nā waiwai kino kūpono i ka noi.

Pono nā crosslinkers no nā pauka uhi UV i nā waiwai o nā crosslinkers i ʻōlelo ʻia ma luna nei i hoʻohana ʻia no ka uhi ʻana i ka pauka thermosetting. Ua synthesized a ua aʻo mākou i ka hana crosslinking o ʻekolu acrylic a me hoʻokahi allyl derivative, kūpono no ʻO nā uhi pauka UV.
