Kāore, e kore tēnei e hoha, he pono - ina koa mēnā he pai ki a koe ngā mea rapa totoro. Ki te pānui tonu koe, ka kitea e koe ngā mea katoa i hiahia koe ki te mōhio mō ngā Hiri Hiri Kotahi-Wāhanga.
1) He aha rātou
2) Me pēhea te hanga i aua mea
3) Kei hea e whakamahia ai
Kupu Whakataki
He aha te hiri silicone kotahi-wāhanga?
He maha ngā momo hiri matū - ko te Silicone, te Polyurethane me te Polysulfide ngā mea e tino mōhiotia ana. I ahu mai te ingoa i te tuarā o ngā ngota e whai wāhi ana.
Ko te tuara o te silicone ko:
Si – O – Si - O – Si – O – Si
He hangarau hou te silicone kua whakarerekētia (i te US pea) ā, ko tōna tikanga he tuara waro kua whakamaroketia ki te matū silane. Hei tauira, ko te waikura polypropylene kua whakamutua te alkoxysilane.
Ka taea e ēnei matū katoa te noho hei wāhanga kotahi, hei wāhanga rua rānei, e pā ana ki te maha o ngā wāhanga e hiahiatia ana hei whakamaroke i te mea. Nō reira, ko te tikanga o te wāhanga kotahi ko te whakatuwhera i te ngongo, te kātereti, te peere rānei, ā, ka whakamaroke tō rauemi. I te nuinga o te wā, ka tauhohe ēnei pūnaha wāhanga kotahi ki te makuku o te hau hei rapa.
Nō reira, he pūnaha pumau te silicone wāhanga-kotahi i roto i te ngongo kia mārō rā anō ina pāngia e te hau, ka puta he rapa silicone.
Ngā Painga
He maha ngā painga motuhake o te silicone wāhanga kotahi.
-Ina tika te whakaranu, he tino pumau, he pono hoki, he pai te piri me ngā āhuatanga ā-tinana. He mea noa te roa o te oranga (te wā ka taea e koe te waiho i roto i te ngongo i mua i te whakamahinga) mō te iti rawa o te kotahi tau, ā, he maha ngā tau e mau ana ētahi hanganga. Ko ngā silicones anō hoki te mea tino pai mō te wā roa. Kāore e rerekē ana ō rātou āhuatanga ā-tinana i te roanga o te wā, kāore he pānga mai i te pānga o te hihi UV, ā, hei tāpiri, he tino pai te pumau o te pāmahana, nui atu i te 50℃ o ētahi atu hiri.
-Ka tere te maroke o te silicones kotahi wāhanga, ka puta he kiri i roto i te 5 ki te 10 meneti, ka kore he piripiri i roto i te kotahi haora, ā, ka maroke hei rapa pīwariwari tata ki te 1/10 inihi te hohonu i roto i te iti iho i te rā. He pai te āhua o te mata, he rite ki te rapa.
-Nā te mea ka taea te hanga kia mārama, he āhuatanga nui tēnei (ko te mārama te tae e whakamahia whānuitia ana), he tino māmā te tāpiri i ngā tae ki tētahi tae.
Ngā Here
E rua ngā ngoikoretanga matua o te silicones.
1) Kāore e taea te peita ki te peita wai - he uaua pea te peita whakarewa.
2) I muri i te whakamaroketanga, ka tukuna e te hiri ētahi o tana kirihou silicone, ā, ina whakamahia ki te hononga whānui o te whare, ka puta he paru kino ki te taha o te hononga.
Heoi anō, nā te mea he wāhanga kotahi noa iho, kāore e taea te tere te whakamaroke i te wāhanga hohonu nā te mea me tauhohe te pūnaha ki te hau, nō reira ka whakamaroke mai i runga ki raro. Ki te whai kōrero taipitopito ake, kāore e taea te whakamahi i ngā silicones hei hiri anake i roto i ngā matapihi karāhe whakamahana nā te mea. Ahakoa he tino pai ki te pupuri i te wai nui ki waho, he ngāwari noa te haere o te mamaoa wai mā roto i te rapa silicone kua whakamarokehia, ka kohu ai ngā wae IG.
Ngā Wāhi Mākete me ngā Whakamahinga
E whakamahia ana ngā silicones kotahi-wāhanga i ngā wāhi katoa, tae atu ki te whakamahinga o ngā herenga e rua kua whakahuatia i runga ake nei, he mea pouri tēnei ki ētahi rangatira whare.
Ko ngā mākete hanga me ngā mākete mahi-ā-ringa te nuinga o te rahinga, ā, muri iho ko ngā motuka, ngā ahumahi, ngā hikohiko me ngā waka rererangi. Pērā i ngā hiri katoa, ko te mahi matua o ngā silicones he piri me te whakakī i te āputa i waenga i ngā papa e rua e rite ana, e rerekē ana rānei, hei ārai i te wai, i te hauhautanga rānei e puta mai ana. I ētahi wā, kāore e rerekē te hanganga engari kia ngāwari ake te rere, ā, ka waiho hei paninga. Ko te huarahi pai ki te wehewehe i waenga i te paninga, te piripiri me te hiri he māmā noa iho. Ka hiritia e te hiri ngā mata e rua, ko te paninga e hipoki ana, e tiaki ana i te kotahi anake, ko te piripiri e pupuri ana i ngā mata e rua kia piri tahi. He rite tonu te hiri ki te piripiri ina whakamahia ki te karaihe hanganga, ki te karaihe whakamahana rānei, heoi, ka mahi tonu ia ki te hiri i ngā papa e rua me te pupuri i a rāua kia piri tahi.
Matū Taketake
Ko te hiri silicone i te āhua kāore anō kia whakamaroketia he rite tonu ki te whakapiri matotoru, ki te kirīmi rānei. Ina pāngia e te hau, ka waikura ngā rōpū pito tauhohe o te polymer silicone (ka tauhohe ki te wai) kātahi ka hono tetahi ki tetahi, ka tukuna te wai, ka hanga mekameka polymer roa e tauhohe tonu ana tetahi ki tetahi tae noa ki te hurihanga o te whakapiri hei rapa whakamiharo. Ko te rōpū tauhohe i te pito o te polymer silicone i ahu mai i te wāhanga tino nui o te hanganga (haunga te polymer tonu) arā, ko te hononga whakawhiti. Ko te hononga whakawhiti e hoatu ana ki te hiri ōna āhuatanga motuhake, pērā i te kakara me te tere o te whakamaroketia, i te kore rānei e tika pērā i te tae, te piri, me ētahi atu nā te mea he rauemi mata kē atu ka whakamahia pea me ngā pūnaha hononga whakawhiti motuhake pērā i ngā whakakī me ngā kaiwhakatairanga piri. Ko te whiriwhiri i te hononga whakawhiti tika te mea nui ki te whakatau i ngā āhuatanga whakamutunga o te hiri.
Ngā Momo Whakaora
He maha ngā pūnaha whakamaroke rerekē.
1) Acetoxy (kakara winika waikawa)
2) Okime
3) Āroki
4) Penehamiuma
5) Amine
6) Aminoxy
Ko ngā oxime, alkoxies me benzamides (e whakamahia whānuitia ana i Ūropi) ko ngā pūnaha e kiia nei he kūpapa, he kore-waikawa rānei. He kakara haukini ngā pūnaha amine me te aminoxy, ā, he mea whakamahi nui ake i ngā wāhi motuka me ngā wāhi ahumahi, i ngā tono hangahanga motuhake rānei o waho.
Ngā Rauemi Mata
He maha ngā wāhanga o ngā whakatakotoranga, ko ētahi he mea whiriwhiri, i runga i te whakamahinga whakamutunga e whakaarohia ana.
Ko ngā rauemi mata tino nui ko te pūmua tauhohe me te hononga whakawhiti. Heoi, tata tonu te tāpirihia o ngā whakakī, ngā kaiwhakatairanga piri, te pūmua kore tauhohe (whakakirihou) me ngā whakakorikori. Hei tāpiri, he maha atu anō ngā tāpiri ka taea te whakamahi pērā i ngā whakapiri tae, ngā patu harore, ngā ārai mura, me ngā whakaū wera.
Ngā Whakatakotoranga Taketake
Ka rite te āhua o te hanganga oxime noa, te hanganga hiri DIY rānei:
| % | ||
| Polydimethylsiloxane, OH i whakamutua 50,000cps | 65.9 | Pūmua |
| Polydimethylsiloxane, trimethylterminated, 1000cps | 20 | Kaiwhakaahua kirihou |

| Te Whakaora Tonu (mm i roto i ngā haora 24) | 2 |
Ka rite te āhua o ngā whakatakotoranga e whakamahi ana i ētahi atu hononga whakawhiti, tera pea he rerekē te taumata hononga whakawhiti, te momo whakatairanga piri me ngā whakakorikori whakamaroke. Ka rerekē paku ō rātou āhuatanga ā-tinana mēnā kāore he whakaroa mekameka e whakamahia ana. Kāore e taea te hanga ngāwari i ētahi pūnaha mēnā kāore he nui o te whakakī uku e whakamahia ana. E kore e taea te hanga i ēnei momo whakatakotoranga i te momo mārama, i te momo mārama rānei.
Te Whakawhanake i ngā Hiri
E toru ngā wāhanga hei whakawhanake i tētahi hiri hou.
1) Te whakaaro, te whakaputa me te whakamātautau i roto i te taiwhanga - he iti noa ngā rahinga
I konei, he whakaaro hou tā te kaimātai matū taiwhanga, ā, i te nuinga o te wā ka tīmata mā te whakamahi i tētahi puranga ā-ringa o te 100 karamu o te hiri hei tirotiro me pēhea te whakamaroke me te momo rapa e hangaia ana. Inaianei kei te wātea tētahi mīhini hou "The Hauschild Speed Mix" mai i FlackTek Inc. He pai tēnei mīhini motuhake mō te whakaranu i ēnei puranga iti 100 karamu i roto i ngā hēkona me te pupuhi i te hau. He mea nui tēnei nā te mea ka taea e te kaiwhakawhanake te whakamātautau i ngā āhuatanga ā-tinana o ēnei puranga iti. Ka taea te whakaranu i te silica kua kohu, i ētahi atu whakakī rānei pērā i te tio kua whakatōkia ki roto i te silicone i roto i te 8 hēkona. E 20-25 hēkona te roa o te tango hau. Ka mahi te mīhini mā te whakamahi i tētahi tikanga centrifuge takirua kore-taurite e whakamahi ana i ngā matūriki hei ringa whakaranu. Ko te rahi mōrahi o te ranunga he 100 karamu, ā, he maha ngā momo kapu rerekē e wātea ana tae atu ki te mea whakakorekore, ko te tikanga kāore he horoi.
Ehara i te mea ko ngā momo kai anake te mea nui i roto i te tukanga hanga, engari ko te raupapa o te tāpiri me te wā whakaranu. He mea nui te tango atu i te hau kia roa ai te wā e mau ai te hua, nā te mea kei roto i ngā mirumiru hau te makuku ka maroke ai te hiri mai i roto.
Kia whiwhi te kaimātai matū i te momo hiri e hiahiatia ana mō tāna tono, ka piki ake ki tētahi mīhini whakaranu aorangi 1 rita ka taea te whakaputa i te 3-4 ngongo iti 110 ml (3oz). He rawaka tēnei rauemi mō te whakamātautau wā-roa tuatahi me te whakamātautau piri me ētahi atu whakaritenga motuhake.
Kātahi ka haere pea ia ki tētahi mīhini 1, 2 karani rānei hei hanga i ngā ngongo 8-12 10 aune hei whakamātautau hōhonu me te tauira a te kiritaki. Ka tukuna te hiri mai i te kohua mā roto i tētahi rango whakarewa ki roto i te kātere e uru ana ki runga i te rango takai. Whai muri i ēnei whakamātautau, kua rite ia mō te whakanui ake.
2) Whakanuia me te whakatikatika pai - ngā rōrahi waenga
I te whanaketanga whānui, ka hangaia te hanganga taiwhanga i runga i tētahi mīhini nui ake, arā, i te 100-200kg te taumaha, tata ki te kotahi pahu rānei. E rua ngā kaupapa matua o tēnei mahi.
a) kia kite mēnā he rerekētanga nui kei waenganui i te rahi 4 pauna me tēnei rahi nui ake ka puta mai i ngā tere whakaranu me te horapa, ngā tere tauhohenga me ngā rahinga rerekē o te paraoa pokepoke i roto i te ranunga, ā
b) ki te whakaputa rauemi e ranea ana hei whakamātautau i ngā kaihoko pea, me te tiki urupare tūturu mai i te mahi.
He tino whai hua anō hoki tēnei mīhini 50 karani mō ngā hua ahumahi ina hiahiatia he iti ngā rahinga, he tae motuhake rānei, ā, kotahi noa te pahu o ia momo e hiahiatia ana kia hangaia i te wā kotahi.
He maha ngā momo mīhini whakaranu. Ko ngā mea e rua e whakamahia whānuitia ana ko ngā mīhini whakaranu aorangi (e whakaaturia ana i runga ake nei) me ngā mīhini whakamarara tere-rahi. He pai te aorangi mō ngā ranunga matotoru teitei, engari he pai ake te mahi a te mīhini whakamarara, inā koa i roto i ngā pūnaha rere matotoru iti. I roto i ngā hiri hanga noa, ka taea te whakamahi i tētahi o ngā mīhini mena ka aro te tangata ki te wā whakaranu me te kaha o te whakaputa wera o te mīhini whakamarara tere-rahi.
3) Ngā rahinga whakaputa tauine katoa
Ko te whakaputanga whakamutunga, ahakoa he puranga, he mahi tonu rānei, e tumanakohia ana he tārua noa i te whakatakotoranga whakamutunga mai i te taahiraa whakanui ake. I te nuinga o te wā, he iti noa te nui (2, 3 rānei ngā puranga, 1-2 hāora rānei o te mahi tonu) o ngā rauemi ka hangaia tuatahitia i roto i ngā taputapu whakaputa, ā, ka tirohia i mua i te whai i te whakaputanga noa.
Te Whakamātautau - He aha te Whakamātautau, ā, me pēhea te Whakamātautau.
He aha
Ngā Āhuatanga Ā-tinana - Te Toronga, te Kaha Kume me te Tauwehenga
Te piri ki te papa e tika ana
Te roa o te oranga - i te tere me te pāmahana rūma
Ngā Auautanga Ora - Te kiri i te roanga o te wā, Te wā kore e piri, Te wā rakuraku me te whakaora i roto i te kiri, Te pāmahana tae Te pumau, te pumau rānei i roto i ngā wai rerekē pērā i te hinu
Hei tāpiritanga, ka tirohia, ka tirohia rānei ētahi atu āhuatanga matua: te matotoru, te iti o te kakara, te waikura me te āhua whānui.
Me pēhea
Ka unuhia he rau hiri, ka waiho kia mārō mō te wiki. Kātahi ka tapahia he pere pōturi motuhake, ka whakanohoia ki roto i tētahi Whakamātautau Kukū hei ine i ngā āhuatanga ā-tinana pēnei i te roa, te modulus me te kaha kukū. Ka whakamahia hoki ēnei hei ine i ngā kaha piri/honohono ki ngā tauira kua whakaritea motuhake. Ka mahia ngā whakamātautau piri ngāwari, āe-kāo, mā te kukume i ngā pīrere o te rauemi kua whakamaroketia ki runga i ngā papa e pā ana.
Ka ine te mita Shore-A i te pakeke o te rapa. He rite te āhua o tēnei taputapu ki tētahi taumaha me tētahi ine me tētahi pito e pēhi ana ki te tauira kua whakamaroketia. Ka nui ake te urunga o te pito ki roto i te rapa, ka ngawari ake te rapa, ā, ka iti iho te uara. Ko te hiri hanga noa kei roto i te awhe 15-35.
Ko ngā inenga kiri i ngā wā, ngā wā kore here me ētahi atu inenga kiri motuhake ka mahia mā te maihao, mā ngā pepa kirihou rānei he taumaha. Ka inehia te wā i mua i te taea te tango ma i te kirihou.
Mō te roa o te oranga, ka pakekehia ngā ngongo hiri i te pāmahana rūma (e 1 tau te roa o te oranga), i ngā pāmahana teitei rānei, arā, 50℃ mō te 1, 3, 5, 7 wiki, me ētahi atu. Whai muri i te tukanga pakeketanga (ka tukuna te ngongo kia whakamatao i roto i te pouaka tere), ka puta te rauemi mai i te ngongo ka kumea ki roto i tētahi pepa ka tukua kia whakamaroke. Ka whakamatautauria ngā āhuatanga ā-tinana o te rapa i hangaia i roto i ēnei pepa pērā i mua. Kātahi ka whakaritea ēnei āhuatanga ki ērā o ngā rauemi hou kua whakaranua hei whakatau i te roa o te oranga e tika ana.
Kei roto i te pukapuka ā-ringa ASTM he whakamārama taipitopito mō te nuinga o ngā whakamātautau e hiahiatia ana.
Ētahi Tohutohu Whakamutunga
Ko ngā silicones kotahi-wāhanga ngā hiri kounga teitei rawa atu e wātea ana. He iti noa iho ō rātou herenga, ā, ki te hiahiatia he whakaritenga motuhake, ka taea te whakawhanake motuhake.
He mea nui kia maroke rawa ngā rauemi mata katoa, kia pumau te hanganga, ā, kia tangohia te hau i te tukanga whakaputa.
He rite tonu te tukanga whakawhanake me te whakamātautau mō tētahi hiri kotahi-wāhanga ahakoa te momo - me whakarite kia tirohia e koe ngā āhuatanga katoa i mua i te tīmatanga o te hanga i ngā rahinga whakaputa, me te mārama hoki ki ngā hiahia o te tono.
I runga anō i ngā whakaritenga o te tono, ka taea te whiriwhiri i te matū whakaora tika. Hei tauira, ki te whiriwhiria he silicone, ā, kāore e kiia he mea nui te haunga, te waikura me te piri engari me iti te utu, ko te acetoxy te huarahi hei whakamahi. Heoi, ki te mea kei roto ngā wāhanga whakarewa kua waikura pea, e hiahiatia ana rānei he piri motuhake ki te kirihou i roto i te tae kanapa ahurei, me whakamahi koe i te oxime.
