Ahakoa he maha ngā āhuatanga pai o ngā kirihou, ehara i te mea ka taea e ngā momo kirihou katoa te whai i ngā āhuatanga pai katoa. Me mārama ngā kaihanga rauemi me ngā kaihoahoa ahumahi ki ngā āhuatanga o ngā momo kirihou kia taea ai te hoahoa i ngā hua kirihou tino tika. Ko te āhuatanga o te kirihou, ka taea te wehewehe ki ngā āhuatanga ā-tinana taketake, ngā āhuatanga miihini, ngā āhuatanga wera, ngā āhuatanga matū, ngā āhuatanga whatu me ngā āhuatanga hiko, me ētahi atu. Ko ngā kirihou miihini e pā ana ki ngā kirihou ahumahi e whakamahia ana hei wāhanga ahumahi, hei rauemi anga rānei. He kirihou ēnei he kaha pai, he ātete pānga, he ātete wera, he pakeke me ngā āhuatanga ārai-pakeke. Ka tautuhia e te umanga Hapanihi hei "ka taea te whakamahi hei wāhanga hanganga me te miihini o ngā kirihou mahi-teitei, he ātete wera i runga ake i te 100℃, e whakamahia ana i te nuinga o te wā i roto i te umanga".
Kei raro nei ka whakarārangihia e mātou ētahi o ngā mea e whakamahia whānuitia anangā taputapu whakamātautau:
1.Taupū Rere Rewa(MFI):
Whakamahia hei ine i te uara MFR o te tere rere rewa o ngā momo kirihou me ngā kapia i roto i te āhua rere matotoru. He pai mō te hanga kirihou pēnei i te polycarbonate, te polyarylsulfone, ngā kirihou fluorine, te nairona me ētahi atu me te pāmahana rewa teitei. He pai hoki mō te polyethylene (PE), te polystyrene (PS), te polypropylene (PP), te kapia ABS, te polyformaldehyde (POM), te kapia polycarbonate (PC) me ētahi atu whakamātautau pāmahana rewa kirihou iti. Tutuki i ngā paerewa: ISO 1133,ASTM D1238,GB/T3682
Ko te tikanga whakamātautau he tuku i ngā matūriki kirihou kia rewa ki roto i te wai kirihou i roto i tētahi wā (10 meneti), i raro i tētahi pāmahana me te pēhanga (ngā paerewa rerekē mō ngā rauemi rerekē), kātahi ka rere atu i roto i tētahi diameter 2.095mm o te maha o ngā karamu (g). Ko te nui ake o te uara, ko te pai ake o te rere o te rauemi kirihou, me te ritenga kē. Ko te paerewa whakamātautau e whakamahia whānuitia ana ko ASTM D 1238. Ko te taputapu ine mō tēnei paerewa whakamātautau ko te Melt Indexer. Ko te tukanga whakahaere motuhake o te whakamātautau ko: ka whakanohoia te rauemi polymer (kirihou) hei whakamātautau ki roto i tētahi awaawa iti, ā, ka honoa te pito o te awaawa ki tētahi ngongo angiangi, ko te diameter he 2.095mm, ā, ko te roa o te ngongo he 8mm. I muri i te whakamahana ki tētahi pāmahana, ka pēhia te pito o runga o te rauemi mata ki raro e tētahi taumaha e whakamahia ana e te piston, ā, ka inehia te taumaha o te rauemi mata i roto i te 10 meneti, koinei te taupū rere o te kirihou. I ētahi wā ka kite koe i te tohu MI25g/10min, ko te tikanga kua puta te 25 karamu o te kirihou i roto i te 10 meneti. Ko te uara MI o ngā kirihou e whakamahia whānuitia ana kei waenga i te 1 me te 25. Ko te nui ake o te MI, ko te iti ake o te matotoru o te rauemi mata kirihou, ā, ko te iti ake o te taumaha ngota ngota; ki te kore, ko te nui ake o te matotoru o te kirihou, ā, ko te nui ake o te taumaha ngota ngota.
2. Mīhini Whakamātautau Kukū Ao Whānui (UTM)
Mīhini whakamātautau rauemi whānui (mīhini kume): te whakamātautau i te kume, te haehae, te piko me ētahi atu āhuatanga ā-pūkaha o ngā rauemi kirihou.
Ka taea te wehewehe ki ēnei kāwai e whai ake nei:
1)Te kaha o te kume&Te whakaroa:
Ko te kaha kume, e mōhiotia ana ko te kaha kume, e pā ana ki te rahi o te kaha e hiahiatia ana hei totoro i ngā rauemi kirihou ki tētahi whānuitanga, e whakaatuhia ana i roto i te nui o te kaha mō ia waeine horahanga, ā, ko te ōrau o te roa totoro ko te roa. Kaha kume Ko te tere kume o te tauira he 5.0 ~ 6.5mm/min te tikanga. Tikanga whakamātautau taipitopito e ai ki a ASTM D638.
2)Kaha ngāwari&Te kaha piko:
Ko te kaha piko, e mōhiotia ana ko te kaha piko, e whakamahia ana hei whakatau i te ātete piko o ngā kirihou. Ka taea te whakamātautau i runga i te tikanga ASTMD790, ā, he maha ngā wā ka whakaatuhia i runga i te nui o te kaha mō ia wāhanga horahanga. Ko te kaha piko o ngā kirihou whānui ki te PVC, te kapia Melamine, te kapia epoxy me te polyester te mea pai rawa atu. Ka whakamahia hoki te muka karāhe hei whakapai ake i te ātete takai o ngā kirihou. Ko te ngāwari piko e pā ana ki te ahotea piko e puta ana mō ia wāhanga nui o te whakarerekētanga i roto i te whānuitanga ngāwari ina piko te tauira (tikanga whakamātautau pēnei i te kaha piko). I te nuinga o te wā, ko te nui ake o te ngāwari piko, ko te pai ake o te pakari o te rauemi kirihou.
3)Kaha pēhanga:
Ko te kaha pēhi e pā ana ki te kaha o ngā kirihou ki te tu atu i te kaha pēhi o waho. Ka taea te whakatau i te uara whakamātautau i runga i te tikanga ASTMD695. He tino pai ngā āhuatanga o ngā kapia polyacetal, polyester, acrylic, urethral me ngā kapia meramin i tēnei āhuatanga.
3.Mīhini whakamātautau pānga cantilever/ Smīhini whakamātautau pānga kurupae tautokona
Whakamahia hei whakamātautau i te pakari o ngā rauemi kore-whakarewa pērā i te pepa kirihou mārō, te paipa, te rauemi āhua-motuhake, te nairona whakapakari, te kirihou whakapakari muka karāhe, te uku, te rauemi whakamahana hiko kōhatu maka, me ētahi atu.
E ai ki te paerewa o te ao ISO180-1992 "te whakatau i te kaha o te pānga o te kirihou - rauemi mārō"; te paerewa ā-motu GB/T1843-1996 "tikanga whakamātautau pānga o te kirihou mārō", me te paerewa ahumahi mīhini JB/T8761-1998 "mīhini whakamātautau pānga kirihou".
4. Ngā whakamātautau taiao: te whakatauira i te ātete o ngā rauemi ki te huarere.
1) Ko te mīhini whakamātautau pāmahana pumau, he mīhini whakamātautau pāmahana me te makuku pumau, he mea whakamahi i ngā taputapu hiko, te rererangi, te motuka, ngā taputapu kāinga, te peita, te ahumahi matū, te rangahau pūtaiao i roto i ngā wāhi pēnei i te pumau o te pono o ngā taputapu whakamātautau pāmahana me te makuku, e tika ana mō ngā wāhanga ahumahi, ngā wāhanga tuatahi, ngā hua haurua-oti, te hiko, te hikohiko me ētahi atu hua, ngā wāhanga me ngā rauemi mō te pāmahana teitei, te pāmahana iti, te makariri, te haukū me te wera, te whakamātautau tonu rānei o te pāmahana me te makuku taiao.
