Ko te hanganga kapia o ngā hiato kirihou werawera e uru ana ki ngā kirihou hangarau whānui me ngā kirihou motuhake, ā, ko te PPS he tohu noa iho o ngā kirihou hangarau motuhake, e mōhiotia whānuitia ana ko te "koura kirihou". Ko ngā painga mahi ko ēnei āhuatanga e whai ake nei: he ātete wera pai, he pai ngā āhuatanga miihini, he ātete waikura, me te mura-ā-roto tae atu ki te taumata UL94 V-0. Nā te mea he pai ngā painga mahi o te PPS i runga ake nei, ā, ki te whakaritea ki ētahi atu kirihou hangarau kirihou werawera mahi-teitei, he ngāwari te tukatuka me te iti o te utu, nō reira kua waiho hei hanganga kapia pai rawa atu mō te hanga rauemi hiato.

He kaha nui, he ātete wera nui, he ātete mura, he ngāwari te tukatuka, he iti te utu, me ētahi atu ngā painga o te rauemi hiato PPS me te muka karāhe poto (SGF).
He pai ngā painga o te rauemi hiato muka karāhe roa PPS (LGF) o te pakari teitei, te iti o te piko, te ātete ki te ngenge, te āhua pai o te hua, me ētahi atu. Ka taea te whakamahi mō ngā impeller, ngā anga papu, ngā hononga, ngā takirere, ngā impeller me ngā anga papu matū, ngā impeller me ngā anga wai whakamatao, ngā wāhanga taputapu kāinga, me ētahi atu.

Nā, he aha ngā rerekētanga motuhake o ngā āhuatanga o ngā hiato PPS kua whakapakarihia ki te muka karāhe poto (SGF) me te muka karāhe roa (LGF)?

I whakaritea ngā āhuatanga whānui o ngā hiato PPS/SGF (muka karāhe poto) me ngā hiato PPS/LGF (muka karāhe roa). Ko te take i whakamahia ai te tukanga whakakī rewa i roto i te whakarite i te whakapūtanga tīwiri he mea ka whakatinanahia te whakakī o te paihere muka i roto i te pokepokea ai, ā, kāore te muka e pakaru. Hei whakamutunga, mā te whakataurite raraunga o ngā āhuatanga miihini o ngā mea e rua, ka taea te whakarato tautoko hangarau mō ngā kaimahi pūtaiao me ngā kaimahi hangarau o te taha tono i te wā e whiriwhiri ana i ngā rauemi.

Te tātaritanga āhuatanga mīhini
Ka taea e ngā muka whakakaha e tāpirihia ana ki te anga kapia te hanga i tētahi anga tautoko. Ina pāngia te rauemi hiato e te kaha o waho, ka taea e ngā muka whakakaha te tu atu i ngā kawenga o waho; i te wa ano, ka taea e ia te mimiti i te kaha mā te whati, te whakarerekētanga, me ētahi atu, me te whakapai ake i ngā āhuatanga miihini o te kapia.

Ina piki ake te nui o te muka karāhe, ka nui ake ngā muka karāhe i roto i te rauemi hiato ka pāngia e ngā kaha o waho. I taua wā anō, nā te pikinga ake o te maha o ngā muka karāhe, ka angiangi haere te hanganga kapia i waenganui i ngā muka karāhe, ā, ka pai ake te hanganga o ngā anga kua whakapakarihia ki te muka karāhe; nō reira, mā te pikinga ake o te nui o te muka karāhe ka taea e te rauemi hiato te whakawhiti i te ahotea nui atu i te kapia ki te muka karāhe i raro i te kawenga o waho, ka pai ake ai te āhua o te kume me te piko o te rauemi hiato.
He teitei ake ngā āhuatanga kume me te piko o ngā rauemi hiato PPS/LGF i ngā rauemi hiato PPS/SGF. Ina 30% te wāhanga papatipu o te muka karāhe, ko te kaha kume o ngā rauemi hiato PPS/SGF me PPS/LGF he 110MPa me te 122MPa; ko te kaha piko he 175MPa me te 208MPa; ko ngā moduli pīngore piko he 8GPa me te 9GPa.
I piki ake te kaha kume, te kaha piko me te modulus pīngore piko o ngā hiato PPS/LGF mā te 11.0%, 18.9% me te 11.3%, ia, ki te whakatauritea ki ngā hiato PPS/SGF. He teitei ake te tere pupuri roa o te muka karāhe i roto i te rauemi hiato PPS/LGF. I raro i te ihirangi muka karāhe ōrite, he kaha ake te ātete kawenga o te rauemi hiato, ā, he pai ake ngā āhuatanga miihini.
