Mā ngā piripiri hou e pakari ana ka roa ake te ora o āu kaupapa
Ngā Whakaaro Matua
- Ngā piripiri pakari-teitei pērā i Ka ātete te HTBN i te ahotea, ngā huringa pāmahana, me ngā taiao uaua. Ka roa ake te ora o āu kaupapa, ā, ka whakaiti i ngā whakatikatika.
- Mā te hanganga ahurei o HTBN ka ārai i te tipu o ngā kapiti. Ka pupuri i ngā hononga kia ngāwari, kia kaha hoki, ahakoa te ahotea, te ngenge rānei.
- Mā te whiriwhiri i ngā piripiri pakari ka roa ake te mau. Ka pai ake te mahi a ēnei i ngā piripiri tuku iho mā te ātete ki te ngenge me te whakaroa i te roa o te ora o ngā hononga kua herea.
Ngā piripiri hou e tino pakari ana: Me pēhea HTBN ārai i te ngoikore o te ngenge
He aha te korenga o te ngenge piri?
Ka puta te ngoikore o te ngenge piri ina ngoikore, ka motu rānei te hononga i muri i te pānga o te ahotea maha i roto i te wā. Ka kitea tēnei i roto i te maha o ngā kaupapa hangarau me te hanga. Ko ngā take tino noa ko:
- Te utaina huringa, arā, ka pāngia te hononga e te pana, te kume, te wiri rānei auau.
- Te utaina pūmau, e kiia ana hoki ko te ngokingoki, ka pōturi te āhua o te piripiri i te kaha pumau.
- Ko te huringa wera, ka puta ina horapa, ka whakawhāiti hoki ngā rauemi i ngā huringa pāmahana.
- Te koroheketanga o te taiao, ina pakaru mārire te piripiri i te makuku, te hihi o te rā, ngā matū rānei.
E whakaatu ana te arotake he rerekē ngā momo rahunga o ngā hononga takahuri kotahi i raro i te kawenga ngenge, ko ngā rahunga piri/piripiri e whakaatu ana i te roa o te ora ngenge me te roa o ngā taupatupatu, ko ngā rahunga piri he rerekē ngā au.
Me mārama koe ki ēnei take nā te mea ka taea e rātou te arahi ki ngā pakaru, ki ngā whati rānei o te paparanga piri. I roto i te wā, ka tipu haere ēnei pakaru iti, ka ngoikore ai te hononga. Ki te kore koe e aro ki ēnei take, tera pea ka hinga wawe tō kaupapa i te wā e tumanakohia ana.
He aha te take e whakapoto ai te roa o te kaupapa i te korenga o te ngenge
Ehara i te mea he iti noa ngā raruraru ka puta mai i te ngoikore o te ngenge. Ka taea e ia te arahi ki ngā raruraru nui mō tō kaupapa. Ina ngoikore te hononga piri, me whakatika, me whakakapi rānei ngā wāhanga, ka pau te wā me te moni. Ka taea e te ngoikore o te piri te arahi ki te ngoikore wawe o te hononga, ka hiahiatia he whakatikatika me te whakakapinga utu nui. He mea nui te whiriwhiri i te piri; hei tauira, e mōhiotia ana ngā epoxies pakari mō tā rātou tikanga whakakore pakaru, e whakarei ake ana i te roa. Ahakoa he ngāwari ngā polyurethane, ka taea e rātou te mimiti i ngā wiri me te whakauru i te whānui wera, e pai ai mō ngā tono me ngā taumahatanga rerekē. He mea nui te maimoatanga mata tika hei ārai i te ngoikore o te piri, ā, me arotau te matotoru o te paparanga piri kia kore ai e pakarukaru. Mā te haumi ki ngā piri kounga teitei ka taea te whakaiti i ngā utu tiaki a meake nei.
Kāore pea koe e kite wawe i ngā pakaru o te ngenge. He uaua ki te kite wawe, ka nui ake te tūponotanga o ngā whati ohorere. Ka taea e ēnei pakaru te whakaiti i te mahi a ngā hononga, ā, ka puta he hua kino rawa atu. I ētahi wā, ko te pakaru o te ngenge te take o te 50-90% o ngā pakaru katoa o ngā hononga piri-piri. Ka taea te wehewehe, te wehenga rānei o ngā paparanga, ina tupu ngā kapiti i roto i te piri. Nā tēnei ka uaua ake te tirotiro me te whakatika, ā, ka tere te pakaru.
Te ātete a te hanganga ahurei o HTBN ki te ngenge
Mā ngā piripiri hou he pakari teitei, pērā i ērā i hangaia ki te HTBN, ka hoatu he painga nui ki ō kaupapa. Ko te HTBN he whakarāpopototanga mō te hydroxy-terminated rapa nitrile butadiene wai. He hanganga motuhake tō tēnei rauemi hei āwhina i a ia ki te whawhai ki te ngoikore o te ngenge. Anei te mahi a te HTBN:
- Kei ngā pito e rua o te mekameka ngota o te HTBN ngā rōpū hydroxyl. Mā ēnei rōpū ka pai te hono atu ki ētahi atu rauemi.
- He mea hanga te tuara o te HTBN mai i te rapa nitrile ngāwari. Mā tēnei ka pakari, ka noho ngāwari tonu ahakoa i ngā pāmahana iti.
- Kei roto i te HTBN te acrylonitrile, e whakapai ake ana i te ātete ki te hinu me te ngāwari.
- Mā te noho mai o ngā rōpū epoxy whakamutunga ka taea HTBN te hono atu ki ngā kapia epoxy, kia pakari ake ai te piripiri.
- He pai te ātete o te HTBN ki te hinu, ki te wera, ki te kakahu, ā, he kaha hoki ki te piri.
