Me whai takirere koe mō te raina matū, engari ehara i te mea he kōwhiringa te whakamahi i te PVC noa. Mēnā ka hē te whiriwhiri i te rauemi, ka puta pea ngā turuturu, ngā maringi kino, me te kino nui ki tō pūnaha katoa.

He takirere kati te takirere pōro PP i hangaia mai i te polypropylene, he pūhui kirihou wera. He mea whiriwhiri motuhake mō tōna ātete tino pai ki te whānuitanga o ngā waikawa, ngā kawa, me ngā whakarewa matū, inā koa ka pakaru te PVC.

Ina kōrero ahau ki aku hoa mahi pērā i a Budi i Initonīhia, he maha ngā wā ka neke atu te kōrero i ngā tono wai paerewa. He maha āna kiritaki e mahi ana i ngā ahumahi pēnei i te tukatuka matū, te maimoatanga wai rānei, he nui ake te kaha o ngā wai i te wai noa. Mō ēnei mahi, mā te whakamahi noa i te wai paerewatakirere PVCKāore e ranea. Me whai rauemi koe kua hangaia hei tu atu ki ngā āhuatanga uaua me te kore e pirau. Ko te nuinga o taua rauemi he polypropylene, he PP rānei. Ka whakarato i te haumaru me te pono e hiahiatia ana mō ēnei tono ahumahi nui.

He aha te āhua katoa o te PP i roto i ngā takirere?

Ka kite koe i te "PP" kua whakarārangihia i roto i tētahi rārangi pukapuka engari kāore koe i te tino mōhio he aha tōna tikanga. Nā tēnei ka uaua ki te rapu i ōna āhuatanga, ki te whakamārama rānei i ōna painga ki ō kaihoko me te māia.

Ko te momo PP katoa i roto i ngā takirere ko te Polypropylene. He kirihou wera tino pakari, he mama hoki, nō te whānau kirihou kotahi pērā i te PVC (Polyvinyl Chloride) me te PE (Polyethylene).

Ko te polypropylene tētahi o ngā kirihou tino maha ngā whakamahinga o te ao. He rauemi mahi nui e whakamahia ana i roto i ngā mea katoa mai i ngā wāhanga motuka ki ngā taputapu taiwhanga nā te mea he āhuatanga ahurei ōna. I roto i te ao o ngā takirere me ngā paipa, ko tōna painga matua ko tōna whakamiharo.ātete matū. Kāore i rite ki te PVC, ka taea e ia te tu atu ki ngā waikawa kaha maha, ngā kawakore, me ngā whakarewa rauropi me te kore e pakaru. Koia mātou i Pntek he raina motuhake mōNgā takirere PP. E mōhio ana mātou kāore he mea hei whakakapi mō ētahi mahi ahumahi. Ko te mārama ko te tikanga o te "PP" he polypropylene te taahiraa tuatahi ki te whiriwhiri i te takirere tika mō tētahi tono matū pakari.

Polypropylene (PP) vs. Polyvinyl Chloride (PVC)

Taonga	Polypropylene (PP)	Pūhaumāota Polyvinyl (PVC)
Ingoa Rauemi	Polypropylene	Polyvinyl Chloride
Whakamahinga Matua	Ahumahi matū, taiwhanga, whakakikorua hiko, ngā tono ahumahi.	Te kawe wai, te whakamakuku, te putorino whare, ngā puna kaukau.
Ātete Matū	Tino pai; inā koa ki ngā waikawa, ki ngā kawakore, me ngā whakarewa.	Pai; engari he ngoikore ki ētahi whakarewa me ngā matū whai kōrote.
Tepe Mahana	Teitei ake; ka taea te whakahaere i ngā wai tae atu ki te 80-90°C (175-195°F).	I raro iho; ko te tikanga he 60°C (140°F).
Tikanga Hononga	He mea noa te whakarewa wera (te whakarewa), e wātea ana hoki me ngā kōhao/miro.	Sima whakarewa (piri) mō ngā pito o te kōhao, te miro.

He aha te pōro PP?

Ka kite koe i tētahi takirere he tinana PVC engari he pōro PP. He āhua rerekē te āhua o tēnei ranunga rauemi, ā, ka whakaaro koe mēnā he mahi whakaiti utu, he āhuatanga rānei he kaupapa tūturu.

Ko te pōro PP he porowhita hurihuri i roto i te takirere i hangaia mai i te polypropylene. He kōwhiringa hoahoa atamai te whakamahi i te pōro PP i roto i te takirere PVC e whakapai ake ana i te ātete matū mō te matua o te takirere me te pupuri i ngā utu kia iti.

He kōrero noa tēnei. Ko te pōro me ngā nohoanga ngā wāhanga o te takirere e pā tonu ana ki te wai, ahakoa kua kati te takirere. Ka kiia rātou ko te "ngā wāhanga kua mākū"Ko te tinana o te takirere, i tētahi atu taha, ka kitea noa iho ina tuwhera te takirere. Mō ngā tono me ngā wai waikura ngawari, kāore pea koe e hiahia kia hangaia te tinana takirere katoa mai i ngā rauemi utu nui, kounga teitei. Mā te whakamahi i tētahipōro PP ātete matūi roto i te tinana PVC paerewa, ka hangaia e mātou he mea utu-whai huatakireree tuku tonu ana i te tiakitanga whakarei ake i ngā wāhi tino nui. Ko te whakarato i tētahi otinga kua whakaritea kia taurite ai te mahi me te tahua mō ngā hiahia motuhake o ō mātou hoa mahi.

He aha te whakatauranga pēhanga o te takirere pōro PP?

E mōhio ana koe he pai te PP mō ngā matū, engari ka taea e ia te tu atu i te pēhanga? Ko te whakamahi i tētahi takirere kāore i te tino arohia he mōrearea nui ki te haumaru, ka arahi pea ki te pakaru o te pūnaha me ngā turuturu matū morearea.

Ko te whakatauranga pēhanga mō ngā takirere pōro PP a Pntek ko PN16, arā, he 16 pae, tata ki te 235 PSI rānei i te pāmahana rūma (20°C). He mea nui kia maumahara ka heke iho tēnei whakatauranga i te pikinga ake o te pāmahana o te wai. Tirohia tonu te tūtohi pēhanga-mahana a te kaihanga.

Tō mātouNgā takirere pōro PPHe pakari te whakatauranga PN16 a Pntek. Ko te tikanga ka taea e rātou te whakahaere i te 16 pae pēhanga, arā, tata ki te 235 PSI. He tohu kounga ahumahi tēnei whakatauranga teitei, engari ehara i te mea koinei te kōrero katoa. Ko te mea nui e whakamāramahia ana e au ki ngā hoa mahi pērā i a Budi, ko tēnei whakatauranga pēhanga e hono tika ana ki te pāmahana o te wai. Ka ngawari haere, ka iti haere te pakari o ngā kirihou wera katoa, tae atu ki te polypropylene, i a rātou e wera haere ana. I a te ngohengohe o te rauemi, ka tino heke tōna kaha ki te pupuri i te pēhanga. Ehara i te mea he mahi kino noa te kore aro ki tēnei pihi 'whakaheke'; he mea morearea hoki. Ka whakaratohia e mātou he tūtohi mārama me ā mātou takirere hei ārai i te rahunga o te pūnaha, me te whakarite kia noho tonu te haumaru o ā mātou kiritaki hei kaupapa matua.

Te Tūranga Hiranga o te Hekenga o te Pāmahana

Te Pāmahana Wai	Te Pēhanga Whakahaere Mōrahi (Taupā PN16)
20°C (68°F)	16 pae (235 PSI)
60°C (140°F)	6.4 pae (94 PSI)
80°C (176°F)	3.2 pae (47 PSI)

Kia mōhio: He tauira tēnei mō te takirere PN16. Tirohia tonu te pepa raraunga Pntek mō ngā tatauranga tika.

He aha te takirere PP-H?

Ka tūtaki koe ki ngā momo PP rerekē, pērā i te "PP-H." Kāore koe i te tino mōhio he aha te tikanga o te "-H", he rerekē rānei ngā rauemi hei whakaaroaro māu i a koe e tono ana.

He mea hanga te takirere PP-H mai i te Polypropylene Homopolymer. He momo PP motuhake tēnei, he tino pakari, e mōhiotia ana mō tōna kaha pai, tōna pakari, me tōna mahi pāmahana teitei, he mea tino pai mō ngā takirere me ngā hononga ahumahi.

Kāore i te ōrite te hanganga o ngā polypropylene katoa. Ko te "-H" he tohu mō te Homopolymer, arā, he mea hanga te kirihou mai i te momo poraka hanga monomer kotahi anake (propylene). Ka hua ake he rauemi tino kaha, he pakari hoki, koinei tonu te mea e hiahiatia ana e koe mō te tinana takirere e hiahia ana kia mau ki te pēhanga teitei me te ātete ki te piko. Tērā atu momo, pērā i ngā copolymer (PP-B, PP-R), e hangaia ana mā te tāpiri i tētahi atu monomer. He ngāwari ake ēnei momo, he kaha ake rānei te pānga i ngā pāmahana iti, e pai ai mō ētahi atu mea, pērā i ngā paipa e hiahia ana kia piko. I Pntek, ka whiriwhiria e mātou te PP-H mō ā mātou takirere ahumahi nā te mea ko tōna pakari me te ātete ki te wera ka whakarato i te mahi pai rawa atu me te roa o te ora ratonga.

Ngā Momo Polypropylene Noa

Momo	Ingoa Katoa	Ngā Āhuatanga Matua	Te Whakamahinga Pai rawa atu
PP-H	Homopolymer	He tino pakari, he kaha, he ātete pai rawa atu ki te wera me te matū.	Ngā takirere, ngā taputapu ahumahi, ngā tāke matū.
PP-B	Poraka Copolymer	He kaha te pānga, inā koa i ngā pāmahana iti.	Ngā pouaka pākahiko, ngā wāhanga ahumahi e hiahia ana kia pakari te pānga.
PP-R	Copolymer Matapōkere	Ngāwari ake, ngāwari ake, ātete pai ki te wera mō te wā roa.	Ngā paipa wai wera me te wai matao.

Whakamutunga

A takirere pōro PPhe wāhanga nui mō te whakahaere haumaru i ngā matū. Mā te mārama ki ngā āhuatanga o ōna rauemi, ngā rohe pēhanga, me ngā momo rerekē pērā i te PP-H, ka taea e koe te whiriwhiri i te takirere tika mō ngā mahi ahumahi uaua.
