He Kupu Whakataki ki ngā Matū Waea me Taura PVC Paoa Iti

Ko ngā rauemi waea me ngā taura PVC (Polyvinyl Chloride) he mea hanga motuhake hei whakaiti i te paowa me ngā tukunga hau paitini i te wā e tahuna ana. Nā tēnei ka waiho hei whiringa nui mō ngā tono e matua ana te haumaru ahi. He mea whakamahi mō te whakamahana me te hipoki i ngā taura hiko, ā, he maha ngā āhuatanga matua o ēnei rauemi:

Te hanganga:Ko ngā matū PVC iti-paowa he mea hanga ki te ranunga o te kapia PVC, ngā mea whakakoi kirihou (pēnei i te dioctyl phthalate me te tri-2-ethylhexyl trimellitate), ngā mea aukati mura (hei tauira, te antimony trioxide, te konumohe trihydrate, me te zinc borate), ngā mea whakau (konupūmā/konupūmā), ngā mea whakakī (konupūmā kāponāte), me ngā mea whakahinuhinu.

Ngā Āhuatanga o te Auahi Iti:He rerekē tēnei i te PVC paerewa, e taea ai te whakaiti i te tirohanga tae atu ki te 90% i roto noa i te 30 meneti nā te paowa matotoru, he mea hanga ngā matū PVC paowa iti kia tutuki ai ngā paerewa haumaru pēnei i te BS EN 61034. Ka taea e ēnei matū te tuku mārama i te iti rawa 60% i te wā e tahuna ana, ā, ka tino whakapai ake i te haumaru.

Ātete ki te muraHe āhuatanga ātete mura tō te PVC nā te mea he nui te haukini kei roto, ā, ka whakarei ake mā te whakamahi i ngā tāpiringa ātete mura. Ka tutuki i ēnei matū ngā paerewa pakari pēnei i te IEC 60332-1-2, UL VW1, me te E84 (taupū horapa mura <25, taupū whakawhanake paowa <50).

 Ngā tono:He mea nui ngā waea me ngā taura PVC iti-paoa, e whakamahia whānuitia ana i roto i ngā taiao morearea pērā i ngā pokapū raraunga, ngā kauhanga, ngā waka rererangi, ngā waka tereina, me ngā whare tūmatanui, hei whakaiti i ngā morearea e pā ana ki te paoa me ngā auahi paitini mēnā ka puta he ahi.

Ngā Wero Tukatuka Noa me ngā Otinga mō ngā Matū Waea me te Taura PVC Paoa Iti

Ko te tukatuka i ngā matū PVC iti-paoa he whakahaere i ngā wero maha, inā koa nā te uaua o te hanganga. Kei raro nei, ka matapakihia ētahi o ngā take tukatuka tino noa me ā rātou otinga:

1. He nui te Ihirangi Whakakī e Ārahi Ana ki te Nekenekehanga Kino me te Taipana Nui

Wero:Hei whakatutuki i ngā āhuatanga paowa iti, he maha ngā wā kei roto i ngā matū PVC ngā taumata tiketike o ngā whakakī kore-waro pērā i te konumohe trihydrate (ATH) te konupora hauwai rānei (Mg(OH)₂) — ko te nuinga he 20-60% te taumaha. Ahakoa ka whakaitihia e ēnei whakakī te paowa me te mura, ka taea e rātou te whakanui ake i te matotoru, te whakaiti i te rere o te wai, me te whakakino i ngā taputapu.

Ngā otinga:

Whakauruhia ngā āwhina tukatuka pēnei i ngā hinu whakahinuhinu o roto/o waho (hei tauira, te konupūmā stearate, ngā ware polyethylene, ngā hinu whakahinuhinu rānei)ngā tāpiringa silicone) i te 0.5-2.0 phr hei whakaiti i te matotoru me te whakapai ake i te rere.

Whakamahia ngā mīhini tango tīwiri-rua me te ōwehenga L/D teitei hei whakapai ake i te whakaranu me te mararatanga o te whakakī.

Whakamahia ngā pūnaha pokepoke me te kaha whāngai kōniko hei whakarite i te whakaranu ōrite.

Kōwhiria ngā whakakī me ngā rahi matūriki kua whakaritea te rahi me ngā maimoatanga mata hei whakapai ake i te hototahitanga me te whakaiti i te pakū.

2. Te Pūmautanga o te Wera

Wero:Ka taea e te PVC te pirau i te wā e tukatukahia ana, inā koa me ngā kawenga whakakī nui me ngā kawenga ātete mura, ka tukuna te hau hauwai pūhaumāota (HCl) ka arahi ki te pirau o ngā rauemi, te tae ke, me te waikura o ngā taputapu.

Ngā otinga:

Tāpirihia ngā whakaū wera pēnei i ngā whakaū kei roto i te konupūmā/konutea i te 2-4 phr hei whakakore i te HCl me te ārai i te pirau.

Whakamahia te hinu pīni soya kua whakapūkaratia (ESO) hei hoa-whakau hei whakapai ake i te pumau o te wera me te pumau o te mārama.

Whakahaerehia te pāmahana tukatuka kia tika (160-190°C) kia kore ai e wera rawa.

Tāpirihia ngā antioxidants phenolic (hei tauira, Bisphenol A i te 0.3-0.5%) hei whakapakari i te ātete ki te koroheketanga i te wā e tukatukahia ana.

3. Hekenga o te Kirihou

Wero:Ka taea e ngā mea whakarewa e whakamahia ana hei whakarei ake i te ngāwari te neke i raro i te wera nui (hei tauira, i roto i ngā pokapū raraunga), ka hua ake he toenga ka whakararuraru i te tuku tohu, ka whakaiti rānei i te roa o te taura.

Ngā otinga:

Whakamahia ngā mea hanga kirihou pūmua kāore e heke ana hei utu mō ngā mea hanga kotahi (hei tauira, DOP, DINP) hei whakaiti i te hekenga.

Whakawhanakehia ngā tauira whānui "kore-wai", i tīmatahia e OTECH, hei ārai i te hekenga o ngā kirihou i roto i ngā taiao pāmahana teitei.

Kōwhiria ngā mea whakapūmau kirihou pēnei i te TOTM, he iti ake te huripokitia, ā, he pai ake mō ngā whakamahinga pāmahana teitei.

4. Te Whakataurite i te Ārai Mura me te Pehi Auahi

Wero:Mā te whakanui ake i te ātete mura mā roto i ngā tāpiringa pēnei i te antimony trioxide (3-5%) me ngā matū brominated (12-15%) ka piki ake te tukunga paowa, ka uaua ki te taurite i ngā āhuatanga e rua. Waihoki, ka taea e ngā whakakī pēnei i te konupūmā kāponāte te whakaiti i te paowa engari ka whakaheke pea i te taupū hāora, ka pā ki te ātete mura.

Ngā otinga:

Whakamahia ngā huinga ārai mura tahi (hei tauira, ATH me te konutea borate) hei whakapai ake i te ārai mura me te pehi paowa. Hei tauira, ka tukuna e te ATH te mamaoa wai hei whakakore i te mura me te hanga i tētahi paparanga waro tiaki, hei whakaiti i te paowa.

Whakawhāitihia te utaina CaCO₃ ki te 20-40 phr kia taurite ai te utu, te pehi paoa, me te ātete mura, nā te mea ka taea e te nui rawa te whakaiti i te taupū hāora.

Tūhurahia ngā whakatakotoranga PVC ka taea te hono-whiti, pērā i te PVC hono-whiti irahiko, hei whakarei ake i te ātete mura me te kore e whakawhirinaki nui ki ngā tāpiringa halogenated.

5. Te Āheinga o te Tukatuka me te Kounga o te Mata

Wero:Mā te nui o te whakakī me te tāpiringa ka hua ake he āhua kino o te mata, he paru o te mate, me te koretake o te whakaputanga, ka pā kino tēnei ki te āhua me te mahi o te hua taura whakamutunga.

Ngā otinga:WhakamahiaPaura silicone SILIKE LYSI-100A. Tēneitāpiringa hangai ki te siliconee whakamahia whānuitia ana heitāpiri tukatuka hinu whai huamō ngā pūnaha kapia hototahi ki te PVC hei whakapai ake i ngā āhuatanga tukatuka me te kounga o te mata. Pērā i te rere pai ake o te kapia, te whakakī me te tukunga o te pokepokea ai, te iti ake o te taipana extruder, me te iti ake o te tauwehenga waku, te nui ake o te mar, me te ātete ki te pakū…

Ngā Painga Matua o te Paura Silicone LYSI-100A mō ngā matū PVC me ngā tono hua whakamutunga:

1) Ngā hononga waea me te taura PVC iti te paowa: he pumau te whakaputanga, he iti te pēhanga mate, he maeneene te mata o te waea me te taura.

2) Waea me te taura PVC waku iti: Tauwehenga waku iti, he maeneene roa.

3) Hua PVC ātete-rakuraku: Ārai-rakuraku, pērā i ngā arai PVC.

4) Ngā kōtaha PVC: he pai ake te whakakī i te pokepokea ai me te tukunga pokepokea ai, kāore he uira pokepokea ai.

5) Paipa PVC: he tere ake te whakaputanga, he iti ake te COF, he maeneene ake te mata, ā, he penapena utu.
