Polyisobutylene (PIB)He matū matotoru, kore tae, kore reka, kore paitini, he ātete wera, he ātete hāora, he ātete ozone, he ātete huarere, he ātete ultraviolet, he ātete waikawa me te alkali me ētahi atu matū he pai te mahi. Ko te Polyisobutylene he homopolymer isobutylene kore tae, kore kakara, kore paitini. Nā ngā tikanga whakarite rerekē me ngā āhuatanga hangarau, he rerekē te nui o te polyisobutylene i roto i te whānuitanga whānui. Ko te nuinga o te taumaha ngota o te hua ka eke ki te neke atu i te 10,000 ki te 200,000 ka huri mai i te wai matotoru ki te haurua-totoka, kātahi ka huri ki te elastomer rite ki te rapa. He ātete te Polyisobutylene ki te waikawa, te alkali, te tote, te wai, te ozone me te koroheketanga, ā, he pai te aukati hau me te hiko.
Ngā āhuatanga matū:He wai matotoru, he wai kore tae, he wai kōwhai mārama, he wai rapa ngāwari, he āhua totoka rānei (he ngawari te taumaha ngota ngota, he ngawari te taumaha ngota ngota, he ngāwari te ngāwari). He kakara kore, he kakara kore, he kakara paku rānei. Ko te taumaha ngota ngota toharite he 200,000 ~ 87 miriona. Ka wairewa i roto i te benzene me te diisobutyl, ka taea te whakaranu ki te polyvinyl acetate, te ware pi, me ētahi atu, kāore e wairewa i roto i te wai, te waipiro me ētahi atu whakarewa porotaka. Ka taea e ia te hanga i te huka kapia kia tino ngawari i te pāmahana iti, ā, he āhua kirihou i te pāmahana teitei hei whakakapi i ngā ngoikoretanga o te polyvinyl acetate i te makariri, i te wera me te ngawari rawa ina tutuki te pāmahana waha.
Ngā tono:E mōhiotia ana te PIB mō ōna āhuatanga hiri me te piri pai, e whakamahia pinepinetia ana i roto i ngā piripiri, ngā paninga, me ngā hiri. Nā ngā āhuatanga rite ki te rapa o te PIB he mea pai rawa atu mō te hiri me te here, nā te mea ka āwhina ki te whakarato i te here kaha me te pakari i roto i ngā tautuhinga maha. Haunga tōna whakamahinga mahi, he mea whakamahi noa te PIB i roto i ngā mea whakapaipai me ngā taonga tiaki whaiaro nā ōna āhuatanga wairewa pai rawa atu. He maha ngā wā ka whakakotahihia te matū me ētahi atu kai hei hanga hua he kakano me te ahua ahurei.
He whānuitia hoki ngā whakamahinga o te PIB i roto i te umanga kai. He mea whakamahi noa te matū hei whakamātotoru, hei whakaū, hei whakakōpiri i roto i ngā kai tukatuka. Ka taea hoki e te PIB te āwhina ki te whakapai ake i te kakano me te matotoru o ngā hua pēnei i te aihikirīmi, te kapia ngaungau, me ngā kai tunua. Nā te maha o ngā whakamahinga o te PIB, he mea nui tēnei hei wāhanga mō ngā kaihanga i roto i te umanga kai.
E whakamahia whānuitia ana hoki te PIB i roto i te umanga hauora. Nā ngā āhuatanga kore-paitini o te matū, he mea tino pai mō te whakamahi i roto i ngā mahi hauora. He maha ngā wā ka whakamahia te matū hei whakaū i roto i ngā kano kano, me te whakauru hoki i roto i te maha o ngā rongoā. Nā te āhua wai-kore o te PIB ka āwhina i a ia ki te piri ki te kiri, ka whai hua ai i roto i te hanga piripiri hauora.
Ngā Āhuatanga:Kei te Polyisobutylene ngā āhuatanga matū o ngā pūhui warowaihā kua kōtui, ā, he rite te tohatoha o te rōpū methyl taha, he pūhui ahurei. Ko te āhua whakahiato me ngā āhuatanga o te polyisobutylene e whakawhirinaki ana ki tōna taumaha ngota me te tohatoha taumaha ngota. Ina kei roto i te awhe 70000~90000 te taumaha ngota toharite matotoru, ka huri te polyisobutylene mai i te wai hurihuri ki te totoka pīataata. I te nuinga o te wā, e ai ki te rahi o te taumaha ngota, ka wehea te polyisobutylene ki ngā raupapa e whai ake nei: polyisobutylene taumaha ngota iti (tau taumaha ngota toharite =200-10000); polyisobutylene taumaha ngota waenga (tau taumaha ngota toharite = 20000-45,000); polyisobutylene taumaha ngota teitei (tau taumaha ngota toharite = 75,000-600,000); polyisobutylene taumaha ngota tino teitei (tau taumaha ngota toharite neke atu i te 760000).
1. Te ātete hau
Ko tētahi o ngā āhuatanga tino pai o te polyisobutylene ko tōna ātete pai ki te hau. Nā te mea e rua ngā rōpū methyl kua whakakapia, he puhoi te nekehanga o te mekameka ngota, ā, he iti te rōrahi kore utu. Ko te hua o tēnei he iti te tauwehenga horapa me te uruhanga hau.
2. Te wairewatanga
Ka wairewa te polyisobutylene i roto i te hauwaiwaro aliphatic, te hauwaiwaro kakara, te penehīni, te naphthene, te hinu kohuke, te hauwaiwaro chlorinated me te waro monosulfide. Ka wairewahia te nuinga ki roto i ngā waipiro me ngā tiihi teitei ake, ka pupuhi rānei ki roto i ngā waipiro, ngā ether, ngā monomers, ngā ketone me ētahi atu whakarewa me ngā hinu kararehe me ngā hinu huawhenua, ka piki ake te nui o te pupuhi me te pikinga o te roa o te mekameka waro whakarewa; Kāore e wairewa i roto i ngā waipiro iti iho (pērā i te methanol, te ethanol, te waipiro isopropyl, te ethylene glycol me te coethylene glycol), ngā ketone (pērā i te acetone, te methyl ethyl ketone) me te waikawa acetic glacial.
3. Ātete matū
He ātete te Polyisobutylene ki te waikawa me te kawakore. Pērā i te haukini, te waikawa hauwaiora, te waikawa hauwaiora 60%, te wairewa mata acetate, te waikawa phosphoric 85%, te hauwaiora konutai 40%, te wai tote kukū, te waikawa whanariki 800%, te waikawa whanariki 38% + te waikura waikawa hauota 14%. Heoi, kāore e taea te ātete ki te waikura o ngā waikura kaha, ngā waikura wera ngoikore (pērā i te pāhare pākawa waro 60%), ētahi waikawa waro wera kukū (pērā i te waikawa acetic 373K) me ngā halogen (fluorine, chlorine, desert).
Tākai: 180KG pahu
Rokiroki: Rokiroki ki te wāhi hauhautanga, maroke, ā, kia tiakina hoki e te rā i te wā e kawe ana.
Hei whakamutunga, he matū whai hua te PIB, he maha ngā whakamahinga i roto i ngā ahumahi rerekē. Nā ōna āhuatanga hiri me te piri pai, tae atu ki tōna wairewatanga me tōna whānui, he mea tino pai mō ngā whakamahinga i roto i ngā ahumahi whakapaipai, tiaki whaiaro, kai, me te hauora. Hei kaiwhakarato matua o PIB, e whakapau kaha ana mātou ki te whakarato i ngā hua me ngā ratonga kounga teitei ki ō mātou kiritaki hei whakatutuki i ngā hiahia o ā rātou ahumahi.
