Ko te whiriwhiri tika i ngā tāpiringa he mea nui hei whakarei ake i ngā āhuatanga tūturu o ngā hiato rakau-kirihou (WPC) me te whakapai ake i ngā āhuatanga tukatuka. I ētahi wā ka puta ngā raruraru o te piko, te ngatata, me te tae ki te mata o te rauemi, ā, koinei te wāhi ka taea e ngā tāpiringa te āwhina. I roto i te raina whakaputanga o ngā WPC, me whai tāpiringa hei whiwhi i te tere whakaputanga tika me te mata maeneene hei karo i te ngatata o ngā taha.
I roto i ngā momo tāpiri kua tīpakohia, ko ngā hinu whakahinuhinu, ngā kaihoko hononga-whiti, ngā ārai-hauora, ngā kaiwhakaū mārama, me ngā kaihoko ārai-pokepokea/ārai-kitakita te mea nui rawa atu te pānga ki te kounga o ngā hiato rakau-kirihou. Mō ngā tāpiri motuhake mō ngā hiato rakau-kirihou, me whakawhanake ngā kapia matrix rerekē i ngā tāpiri motuhake hei whakatutuki i ngā whakaritenga o te mahi hua hiato, te mahi tukatuka rānei, heoi, he whānuitia ngā tāpiri mō ngā hiato rakau-kirihou, ā, he mea nui te whiriwhiri i ngā tāpiri tika mō te hanga hiato rakau-kirihou.
Te Tūranga o ngā Tāpiri i roto i ngā Hikoi Rakau-KirihouNgā Momo me ngā Painga
Kaihoko hononga whakawhiti
Ka honoa ngā muka rakau me te kapia matrix e ngā ākena whakawhiti, ka whakapai ake i te kaha piko me te pakari o te rauemi hiato, me te whakapai ake hoki i te modulus o te ātete ki te pakaru me te modulus o te ngāwari. Ka whakapai ake hoki ngā ākena whakawhiti i te pumau o ngā āhuatanga o te rauemi, te kaha pānga, ngā āhuatanga marara mārama, me te whakaiti i te ngoki, he mea tino nui tēnei mō ngā hua pēnei i ngā papa rākau, ngā reera arawhata, me ngā reera ārai. Mō ngā hiato rakau kirihou e whakamahia ana i roto i ngā rauemi whakapaipai, ko te mahi matua a te ākena whakawhiti ko te whakaiti i te mimiti wai o te rauemi, ka taea ai te karo i te pakaru ahotea i puta mai i te whānui o ngā muka rakau nā te mimiti wai.
Ārai mate
Mō ngā hua rakau kirihou, ko te kōwhiringa matua mō te ārai mate ko te BHT me te 1010 e rua ngā wāhanga. He iti ake te utu o te BHT, ā, he pai te pānga o te waikura ātete-wera i muri mai, engari ko te BHT tonu i muri i te whakakotahitanga o te waikura, ka hanga he DTNP, ko te hanganga tonu he tae kōwhai, kei runga i te hua o ngā tae kua pania, nō reira kāore i te whānui te tono. Ehara i te mea ko ngā hua rakau kirihou anake te 1010 engari i roto i te mekameka umanga pūmua katoa, he whānui ngā tono, ā, ko ia hoki te ārai mate matua nui rawa atu me te tino whānui te whakamahi i te ao.
Ngā rongoā ārai-hae/ārai-huakita
I tēnei wā, ko ngā kaihoko ārai-pokepokea rakau me ngā kaihoko patu huakita he momo tote boron me te konutea, he hua o te pokepokea ai me ngā huakita pirau-rakau he kaha ārai, engari he pai hoki te pumau o te wera me te pumau o te UV, ka taea hoki e te hononga te whakapai ake i ngā āhuatanga ārai-mura o te rauemi, engari he nui te nui o te tāpiri hua, he nui te utu tāpiri, ā, he kino te awe o ngā āhuatanga miihini o ngā hua rakau kirihou; ko tētahi atu momo ko ngā matū waro kei roto te arsenic, he whānui te whakamahinga o te hanganga o ngā kirihou. He iti noa te nui o ngā tāpiri, he ātete pokepokea ai, me ētahi atu āhuatanga, engari nā te mea kei roto te arsenic i roto i te matū, kāore i te eke ki te tiwhikete REACH me ROSH, nō reira he iti ake te whakamahinga a ngā kaihanga rakau kirihou.
Ka taea e ngā hinu whakahinuhinu te whakapai ake i ngā āhuatanga o te mata o ngā mea hanga rakau kirihou, me te whakapiki ake i te hua. Ko ngā hinu whakahinuhinu e whakamahia ana i roto i ngā mea hanga rakau kirihou ko te ethylene bisceramide (EBS), te zinc stearate, te paraffin wax, te polyethylene oxidized, me ētahi atu. He whānuitia te whakamahinga o te EBS me te zinc stearate i roto i ngā mea hanga rakau kirihou HDPE, engari nā te mea ka ngoikore te pānga whakawhiti-hononga o te maleic anhydride i te aroaro o te stearate, ka heke te whai huatanga o ngā kaihoko whakawhiti-hononga me ngā hinu whakahinuhinu. Nō reira, kei te whanake tonuhia ngā momo hinu whakahinuhinu hou.
Ka Tūtaki te Whai Hua ki te Oranga Tonutanga:Ngā Hinu Whakahinuhinu Tino Pai mō te WPC Hoa-Taiao!
To whakatika i te raruraru o te hinu whakahinuhinu rakau-kirihoumākete, kua whakawhanakehia e SILIKE he raupapa ongā hinu whakahinuhinu motuhake mō ngā hiato rakau-kirihou (WPC)
He hua motuhake tēnei he pūhui silicone, he mea hanga motuhake mō ngā rauemi hiato rakau-kirihou. Ka whakamahia he mekameka polysiloxane motuhake i roto i ngā ngota hei whakatutuki i te whakahinuhinu me te whakapai ake i ētahi atu āhuatanga. Ka taea e ia te whakaiti i te waku ā-roto me te waku ā-waho o ngā rauemi hiato rakau-kirihou, te whakapai ake i te kaha reti i waenga i ngā rauemi me ngā taputapu, te whakaiti pai ake i te taipana taputapu, te whakaiti i te whakapaunga pūngao, me te whakapiki ake i te hua.
Te mea nui oTe hinu whakahinuhinu a SILIKE mō ngā rauemi rakau-kirihou, ki te whakaritea ki ngā tāpiringa rauropi pēnei i te stearates me ngā ware pi PE, ka taea te whakanui ake i te kaha whakaputa, Ka mau tonu ngā āhuatanga miihini pai.
Whakatuwheratia hengā otinga matomato mō te HDPE/PP/PVC/ me ētahi atu hiato rakau-kirihou. He whānuitia te whakamahinga i roto i ngā ahumahi tāonga whare, hanga whare, whakapaipai, motuka, me te kawe waka.
Ngā painga noa:
1) Whakapai ake i te tukatuka, whakaitihia te taipana extruder, me te whakapai ake i te marara whakakī;
2) Whakaitihia te waku ā-roto, ā-waho hoki, whakaitihia te whakapaunga pūngao, me te whakapiki ake i te pai o te whakaputa;
3) He pai te hototahi ki te paura rakau, kāore e pā ki ngā kaha i waenga i ngā ngota o te kirihou rakau
ka whakakotahi, ā, ka pupuri i ngā āhuatanga ā-pūkaha o te papa anō;
4) Whakaitihia te nui o te hototahi, whakaitihia ngā hapa o te hua, me te whakapai ake i te āhua o ngā hua rakau kirihou;
5) Kāore he ua i muri i te whakamātautau kohua, kia mau tonu te maeneene mō te wā roa.
Kei raro nei tētahi pukapuka iti oNgā hua hinu whakahinuhinu a SILIKE mō ngā hiato rakau-kirihouka taea e koe te tirotiro, ā, ki te hiahia koe ki ngā hinu whakahinuhinu rakau-kirihou, Whakarei ake i tō Hanganga Hikohiko Rakau-kirihou, Whakahou i te Kounga! E mihi ana a SILIKE ki tāu patai!
