Styrene Āhua-Ahumahi: He Kaihanga Resin Matua mō te Hanga

Styrene Āhua-Ahumahi: He Kaihanga Hanga Resin Matua Whakaahua Matua

whakaahuatanga poto:

Tauira ngota: C₈H₈

Ko te Styrene he hua matū hinu matua, he monomer polymer maha-whakamahinga e whakamahia whānuitia ana i roto i ngā ahumahi o te ao. Ko tēnei wai hinu kore tae, mārama, he kakara kakara motuhake, kāore e wairewa i roto i te wai engari ka taea te whakaranu ki te nuinga o ngā whakarewa rauropi, ka waiho te styrene hei rauemi mata nui mō te hanga kirihou. Hei takawaenga matua, ka whakamahia te styrene hei hanga polystyrene, te kapia ABS, me te rapa hangai, e akiaki ana i ngā auahatanga i roto i ngā rāngai takai, hanga, me te motuka. He mea nui, he ngāwari te styrene ki te polymerization i te pāmahana rūma, nō reira he mea nui ngā aukati pēnei i te hydroquinone mō te rokiroki me te kawe haumaru. Nā ōna āhuatanga matū pumau me te whānui o te whakamahinga, ko te styrene tonu te tūāpapa o te hanga polymer hou, e tautoko ana i ngā mekameka ahumahi kanorau puta noa i te ao.

Styrene (CAS 100-42-5)he monomer matū hinu nui, he poraka hanga matua hoki mō te hanga pūmua hou, e whakanuia ana mō tōna kaha whakapūmua tino pai me te hototahi ki ngā rauemi. Hei rauemi whāngai maha-whakamahinga, ka mahi hei kai matua mō te hanga pūmua mahi-teitei, e āhei ai te hanga rauemi pakari, mahi-ā-tinana e tutuki ai ngā whakaritenga ahumahi tino pakari.

He whānuitia te whakamahinga puta noa i ngā rāngai o te ao, ā, e whakamahia ana mō te hanga polystyrene (PS), te kapia ABS, te rapa styrene-butadiene (SBR), me ngā kapia polyester kāore i te mākū (UPR), e tautoko ana i ngā ahumahi pēnei i te takai, ngā wāhanga o roto o ngā motuka, te whakamarumaru hanga, ngā whare taputapu hiko, me ngā papa taputapu hauora.

He maha ngā momo whiringa o tā mātou hua styrene (ahumahi, polymerization, me te parakore teitei) kia rite ki ngā hiahia whakaputa kanorau, me te whakahaere kounga tino pakari kia iti ai te ihirangi poke me te pumau o te tauhohenga monomer. Ka oati mātou ki te tuku pono i te nuinga, ngā tuhinga taonga morearea katoa (tae atu ki te MSDS, te tiwhikete UN), me ngā otinga whakahaere kua whakaritea mō te kawe wai mura. Hei tāpiri, ka whakaratohia e tā mātou tīma hangarau ngaio te tautoko whaiaro - pēnei i te kōwhiringa aukati me te aratohu rokiroki - hei whakapai ake i te pai me te haumaru o tō whakaputanga.
