He aha te mata o te parepare o mua?
Ko te mata o te parepare o mua he whatu o ngā wāhanga mata o te taha mua o te motuka, kei waenganui i te parepare o mua me te kurupae o mua o te tinana. Ko ōna mahi matua ko:
Te tiaki me te whakapūhautanga: Ko te mata o mua o te parepare e tiaki ana i te whakapūhautanga o te tāke wai, te miihini, te hauhautanga me ētahi atu wāhanga hei ārai i te kino o roto o te motuka i puta mai i ngā mea ke i te wā e taraiwa ana.
Te ataahua me te tuakiri: Haunga ngā mahi whai hua, ka taea hoki e te mata o mua o te parepare te whakanui ake i te ataahua o te motuka me te whakaatu i te tuakiri.
Te whakaurunga me te ātete hau iti iho: Haunga te ataahua, ko te mahi nui a te mata o mua o te parepare ko te whakaurunga me te ātete hau iti iho. Ka whakapai ake i te whai huatanga me te mahi a te motuka mā te whakaiti i te ātete hau.
Paepae hau hohe: Ko te paepae hau hohe he paepae hau whakatuwhera me te kati ka taea te whakarite, ka taea te whakarite i te āhua tuwhera, kati rānei o te paepae hau kia rite ki te tere me te pāmahana o roto kia urutau ki ngā āhuatanga taraiwa rerekē.
Ko te hoahoa me te mahi o te mata o mua o te parepare e whakaata ana i te auahatanga hangarau me te whai i te ataahua i roto i te hangarau motuka, ā, he wāhanga nui o te hoahoa motuka hou.
Kua pakaru tetahi o ngā mata hau whakauru. Me whakakapi katoa? Kei ngā hiahia takitahi te tikanga. I te nuinga o te wā, ka taea te whakatika i te mata hau whakauru pakaru ki te kāpia 502, ā, kāore e pā ki te haumaru o te waka. Engari kāore te whakatikatika i te pai pērā i te mea hou, nō reira, ki te hiahia koe ki te tino pai, me whakakapi katoa.
Kāore koe e hiahia ki te whakakapi i te mea hou, ki te whakatika i te mea tawhito, kātahi ka peita kia whakamahia anō. Nā te mea he kirihou te parepare o mua o te motuka, me whai i ēnei whakaritenga te parepare o te peita rehu me te whakamahi anō: Tuatahi, me mau tonu te whitiki pumau o te parepare, engari he pakaru kei te parepare anake.
Me huri. Ki te kore e whakatikahia te parepare o mua, ka nui ake pea te pakaru i te wā e taraiwa ana i ia rā, ā, ka pā ki te haumaru o te motuka. I roto i ngā wāhanga o waho katoa o te motuka, ko te wāhanga tino ngoikore ko ngā parepare o mua me muri. Ki te tino hē te āhua o te parepare, ki te pakaru rānei, me whakakapi noa.
Ka taea te whakatika, engari he uaua ki te mahi i ngā whakatika tino tika. Waruhia noa, whakangawarihia, ka peita anō. Ka taea te whakamahana i te pakaru ki te hau wera, kātahi ka hutia ki muri, kātahi ka pania ki te kāpia, kātahi ka waruhia, ka hurihia, ka peitahia. Ko te nui o te angitu e whakawhirinaki ana ki te manawanui me te mahi toi a te tohunga.
Ka pā tēnei ki te mahi noa o te waka, nō reira me whakatika. Ko te mata o mua o te waka, me te pare o te tāke wai, he mea nui ki te whakapūmau i te hau o te tāke wai, te miihini, te hauhautanga, me ētahi atu, hei ārai i te kino o ngā mea ke ki ngā wāhanga o roto o te waka i te wā e taraiwa ana, ā, he mea whakapaipai hoki.
Ko te parepare o te motuka he momo taputapu (ngā wāhanga mau) o ngā wāhanga tinana, kei mua o te motuka (e kiia nei ko te parepare o mua) me muri o te motuka (e kiia nei ko te parepare o muri): he teitei te ira rewa (tae atu ki te 167℃), he ātete wera, he mātotoru (0.90g/cm3), koia te mea māmā rawa atu i roto i te kirihou whānui o nāianei, ā, he teitei te ātete waikura (kaha kume 30MPa); He pai ngā āhuatanga o te kaha, te pakari me te mārama o ana hua, ko te ngoikoretanga he ngoikore te ātete pāmahana iti (e toru ngā momo rauemi kua whakarerekētia e te pānga PP copolymer, styrene elastomer me te polyolefin rubber; He pakari teitei, he ātete pānga, he ātete rakuraku me te kaha paninga, ka taea te werohanga i te parepare i muri i te utaina, ka pāngia ki te 8km/h te pānga, ā, he rite te manawanui, te mahi me te PU, ka heke te utu mā te 10%20%).
Ko te nuinga o ēnei he mea hanga ki te rapa pp me te EPDM, ā, ko te parepare waka he taputapu haumaru e mimiti ana, e whakaroa ana hoki i te kaha pānga o waho, e tiaki ana hoki i te taha mua me te taha muri o te tinana. He maha ngā tau ki muri, i pēhia ngā parepare o mua me muri o te waka ki roto i te maitai hongere me ngā pereti maitai, i herea, i whakapirihia rānei ki te kurupae roa o te anga, ā, he āputa nui ki te tinana, he āhua kino rawa te āhua.
E toru ngā wāhanga o te parepare kirihou: te pereti o waho, te rauemi parepare me te kurupae, ko te pereti o waho me te rauemi parepare he mea hanga ki te kirihou, ko te pereti hurihuri matao o te kurupae ka tāia ki roto i te mokowā āhua-U, ko te pereti o waho me te rauemi parepare ka piri ki te kurupae, ā, ko te kirihou e whakamahia ana i roto i te parepare kirihou he mea hanga ki te polyester me te polypropylene.
