Ko te whakamātautau kume o ngā rauemi whakarewa he tikanga matua mō te aromatawai i ō rātou āhuatanga miihini, ā, he mea nui rawa atu. Mā te ine i ngā tawhā pēnei i te kaha kume, te kaha tuku, me te roa, ka inehia te kaha kawe kawenga me ngā āhuatanga whakarerekētanga kirihou o te rauemi. Ka whakaratohia he pūtake haumaru mō te hoahoa hangarau, ā, ka whakarite i te pono o te hanganga. He taputapu whakahaere kounga nui hoki, e manatoko ana i te pumau o ngā tukanga whakaputa me te whakarite kia tutuki i ngā paerewa o te ao. Hei tāpiri, ka taea e ia te matapae i te mōrearea o te rahunga rauemi i raro i ngā kawenga uaua, ā, ka whakarato tautoko raraunga nui mō te whanaketanga o ngā rauemi hou.
Koinei te whakataurite i ngā tikanga whakamātautau kume mōngā paipa rino ngāwarimeNgā paipa SML, e rua ēnei e āwhina ana ki te whakarite i te kounga o te hua me te whakamahinga roa i roto i ngā āhuatanga o te ao tūroa.
1. Ngā Tauira Rerekētanga
Ko te matotoru me te whānui o te tokotoko whakamātautau o ngā tauira rino ngāwari koia ēnei:
| Momo maka | Te whānui ingoa o te pae whakamātautau (mm) | Te rerekētanga rohe diameter (mm) | Te ātete whānui (mm) |
| Te matotoru o te pakitara o te paipa rino ngāwari (mm) e<6 6≤e<8 8≤e<12 12≤e | 2.5 3.5 5.0 6.0 | ±0.06 | 0.03 |
| Ngā paipa rino kore-pūngoi, ngā hononga, me ngā taputapu tāpiri: - Ngā tauira whakarewa whakauru: - Ngā tauira whakarewa wehewehe: Mō ngā tauira he 12.5 mm te matotoru, me iti iho i te 12 mm te matotoru whakarewa. Mō ngā tauira he 25 mm te matotoru, me ≥ 12 mm te matotoru o te whakarewanga. | 5.0 6.0 12.0 14.0 rānei | ±0.06 ±0.06 ±0.09 | 0.03 0.03 0.04 |
Kia mōhio: He mea hanga te pae whakamātautau mai i te tauira mīhini, e tohu ana i te konganuku kei waenganui o te matotoru o te tauira. Kei roto he wāhanga porotaka. Kei te whakaaturia te whānui o te rango i te ripanga i runga ake nei. Ko te roa o te pae whakamātautau he 5 ngā wā neke atu i tōna whānui. Me pai te pito o te pae whakamātautau mō te whakairi ki roto i te taputapu mīhini whakamātautau. Ko te taratara o te mata o te wāhanga porotaka o te pae whakamātautau he Rz ≤ 6.3.
He rino maka hina te mea hanga o te paipa SML, ā, me rite te tauira ki te ahua e whai ake nei:
Kia mōhio: Hei whiwhi i ngā hua whakamātautau e whakaatu ana i te hua kua oti, me tango te tauira whakamātautau mai i te paipa SML, i te hononga SML rānei, ka tapahia kia whakarara ki te tuaka o te ngongo, o te hononga rānei. Me ine te horahanga whakawhiti taketake o te tauira. Me ine tika te whānui me te matotoru o te whakawhiti ki te 0.1mm i mua i te whakamātautau.
2. Ngā rerekētanga o te tukanga whakamātautau
Ahakoa e whakamahia ana tētahi mīhini whakamātautau kume ā-ao hei whakahaere i ngā whakamātautau kume e rua, he rerekē ngā taputapu e whakamahia ana.Kei raro nei te whakaaturanga o te taputapu whakamātautau kume mō te rino ngawari:
Kei raro nei te whakaaturanga o te paipa SML me te taputapu whakamātautau kume:
3. Ngā Rerekētanga i waenga i ngā Hua Whakamātautau me ngā Āhuatanga Rauemi
Ko te tukanga whakarewa me te hanga rino ngāwari he hua o ngā tau maha o te kohikohi hangarau me te tikanga mahi pakari. Ka hangaia e tā mātou kamupene ngā paipa rino ngāwari kounga teitei, me te tere porowhita o te 90% neke atu rānei. Mā te whakamātautau kume ka kitea he kaha kume i waenga i te 460MPa me te 490MPa, me te roa i waenga i te 10% me te 17%. E ai ki ngā paerewa EN545 me ISO2531, ko te kaha kume o te 420MPa neke atu rānei me te roa o te 5% ki te 10% neke atu rānei e kiia ana he pai. Ko te kaha kume me te roa paerewa e whai ake nei:
Ko ngā paipa me ngā hononga SML he mea hanga ki te rino maka hina te nuinga. Ka mimiti te hanganga karāpeti maramara i roto i te rino maka hina i te wiri wai, ka hua ake he iti iho i te 10dB te haruru o te rerenga wai i ngā paipa PVC. He pai rawa atu hoki te ātete pāmahana teitei, neke atu i te 1,000°C. Ka mau tonu te mahi a ngā mowhiti rapa hiri ahakoa i te 70°C tonu, i te 120°C rānei te tukunga wā-poto, me te whakarerekētanga wera kotahi-whitu noa iho i ngā paipa PVC. He pai hoki te kaha kume, te ātete pānga, me te ātete ki te pakū, e rima ngā wā i te iti rawa i ngā paipa PVC.
E ai ki te paerewa EN877, ko ngā āhuatanga ā-pūkaha o ngā paipa me ngā hononga SML koia ēnei:
| Momo whakarewa me te rauemi | Te kaha kume iti rawa （Mpa） |
| Paipa: Rino maka hina | 200 |
| Taunga: Rino maka hina | 150 |
Ngā paipa me ngā hononga SML, ngā paipa PVC, te whakamātautau kume o ngā paipa me ngā hononga SML EN877, te hononga SML, ngā paipa rino ngawari EN545 ISO2531 me ngā paipa SML, ngā tauira rino ngawari, te paipa SML, te paipa rino maka hina,
