Kirihou me ratou tono. kirihou porosity

Various momo o kirihou whakarato whai wāhitanga rahi mo te hanganga o etahi hanganga me ngā wāhanga. Ko reira kahore tāpiritanga enei āhuatanga e whakamahia i roto i ngā mara: i engineering me te engineering irirangi ki rongoa me te ahuwhenua. Paipa me wāhanga mō te mīhini, te tuuraa i rauemi, kuhunga mo taputapu me ngā tūemi whare - he rārangi nui o te mea e taea te hanga i te kirihou.

Ko te momo matua

Kirihou me ratou whakamahinga e hāngai ana i runga i te mea waerau à - tūturu waihanga ranei. E waiho i raro ratou ki te wera, te pēhanga, a ka te raveraa i tuhinga niao o rerekē whīwhiwhi. Ko te mea matua ko te e ka ki enei whawhe pupuri i te ahua o te hua oti. He rewarau kirihou katoa, e he reversible, me rewatau (tina heke).

Reversible hei kirihou i raro i te mana o te whakawera anō me te pēhanga, me huringa uruhi i roto i te hanganga e kore e tupu. Ko taea tonu te kōpeketanga me kua kua riro he hua u ki te fakamolū ka hoatu te hanga i te reira. momo mohiotia o taua kirihou (rewarau) pērā i polyethylene me te terei. he ātete ki te waikura, me ngā āhuatanga uruhanga Origin. I te pūtake hangaia ona putorino, kiriata, pepa, Kei te whānui whakamahia reira hei rauemi tuuraa.

O te styrene ki te terei

Ka rite ki te hua o te polymerization o styrene ko terei rite. Mai i reira i roto i te heke mai te hanga i te wahi ngā i runga i te pūtake o te makanga rû ranei. Kei te whānui peheé kirihou whakamahia mo te hanga o nga wahi nui, me ngā hua, pērā i refrigerators huānga mō bathrooms ranei. I roto i Kei te maha rewatau kirihou whakamahia pressporoshki, laminates, whakapakaritia te muka kirihou, e taea te atu tukatuka ki te whiwhi ngā ngā wāhanga.

Kirihou - tino ngāwari ki te whakamahi, me te, i runga i te pūtake o e taea e koe te hanga i te rota o taonga. Tei runga i te āhuatanga waiariki e te whai i ngā momo o kirihou :

1. Te pēhi i. Ko reira te ara tino rongonui o te whiwhi hua i ngā rauemi rewatau. kawea niao i roto i roto i te pakete motuhake i raro i pāmahana teitei, me te pēhanga.
2. niao i werohia. hanga i tēnei tikanga e taea ki te hanga i ngā hua o ngā āhua rerekē. Hoki tenei waka tauā motuhake ki tonu i te kirihou whakarewa. tukanga iho āhuatanga e hua tiketike, me te kakama.
3. Tangohanga. Na roto i taua tukatuka riro maha momo o ngā hua kirihou, pērā i putorino, ngangana, aho, kiriata o ngā mahi rerekē.
4. Whakatangi. Tenei tikanga - te whai wāhi tino ki te waihanga i tētahi hua o te puka nuinga, e ka whai i te tui i runga i te kati wahi o te pokepokea ai.
5. Takahi. E hanga ana tēnei ara hua i ngā rau kirihou me paraharaha ki āhua motuhake.

Āhuatanga polymerization

Ka taea te whiwhi te kirihou i te polymerization me polycondensation. I roto i te take tuatahi e hono ana i te rāpoi waetahi ki te hanga i te mekameka polymer kahore tuku o te wai me te waipiro, i roto i te tuarua - e-hua e hanga e, e kore e herea ki te waerau. Various tikanga me ngā momo o kirihou polymerization reira taea ki te whiwhi tito e rerekē āhuatanga tuatahi. He wāhi nui i roto i tenei tukanga takaro e te pāmahana tika me te wera o te tauhohenga ki te hanganga niao polymerize tika. I roto i te polymerization he mea nui ki te whakarongo ki te waetahi wäriu - atu i ona iti, atu pono, me te muri ka kirihou roa i roto i te mahi.

porosity

Ki te mea kua kua tukinotia e te aratau polymerization, taea arahi reira ki hē i roto i ngā hua oti. mirumiru ratou puta, vete, me te ahotea ā-nui haere. He momo rerekē o te porosity kirihou:

1. Gas. puta te reira no te mea takahi te aratau polymerization te, a whewhe benzoyl hauwai. Ki te hanga e te kōputaputa hau i roto i te matotoru o te prosthesis, kua hiahiatia reira ki te whakaputa ke.
2. puta porosity potakataka tika ki te puehu waerau te taikaha, te whakaetonga o waetahi i te mata o te kounga rauemi iti Mixing o te hanganga kirihou ranei.
3. Ko te porosity o te kōpeketanga. Puta no te mea te whakaiti i te rōrahi o te papatipu polymerizing i raro i te pānga o te iti pēhanga kore o te hanganga niao ranei.

He aha ki te whakaaro?

kia mohio koe he aha te momo o kirihou he porosity, a ki te ārai hē i roto i te hua whakamutunga. Ko reira e tika ana ki te whakarongo ki te porosity iti i runga i te mata o te prosthesis. tupu tenei no te mea o te moni nui rawa o te waetahi, ai kore e waiho i raro i te porosity ki te orooro. Ki te, i roto i te mahi ki te kirihou i hanga ahotea wäriu ā, e anganga te hua. whakatika te āhuatanga taua e tika ana ki te maumaui aratau polymerization, ina ko roa rawa te ahanoa i roto i te wai kohua.

I roto i tetahi take, te ino o te āhuatanga pūkaha o rauemi polymer i roto i te mutunga arata'i ki te hoholo, engari no te mea ki te hangarau production tika ū tino.

kirihou Basic - he aha te mea te reira?

rauemi tirohia whānuitia whakamahia i roto i te hanga o turanga prostheses pereti tango. Ko te momo tino rongonui o kirihou taketake he turanga waihanga. Mass mō turanga, te tikanga he huinga o te paura, me te wai. A, no te e konatunatua ratou, hanga te hanganga niao e nei whakapakeketia noa i raro i whakawera ranei. Tei runga i te rauemi whiwhi e te wera-haamărôraa whaiaro pakeke-ranei. Ki te kirihou taketake ngā polymerization wera:

• Etacryl (AKP-15);
• akrel;
• ftoraks;
• Akron.

Materials ki te waihanga niho more he kirihou ngāwari, e kua hiahiatia rite te Pads ru-ngongo ngohengohe mō turanga. Me waiho ratou haumaru mo te tinana, mau hono ki te turanga o te prosthesis, mau tonu ngäwari me te rōrahi tamau. I roto i taua kirihou taa'eraa eladent te ngohi te e ki prosthesis katoa, me ortoksil nei kua riro mai i runga i resins siloxane.

rauemi hanga

Ko te momo matua o kirihou e whakamahia i roto i mara ngā o te hanga, i runga i te hanganga rānei. ngā te rauemi tino rongonui te whai ake:

1. raima waerau. Tenei kapia hiato, hanga nei i runga i te pūtake o waerau rewatau. Ko te pai i roto i ngā o ngā āhuatanga ōkiko me te pūkaha whakaaro e resins epoxy Waerau-e hāngai ana. utua brittleness o te rauemi e taima kaiota te - papa kiripaka, weu karaihe. E whakamahia Waerau raima ki te waihanga hanganga e te hunga ātete ki ngā matū.
2. GRP - hou momo o te hanganga kirihou, e he pepa o muka karaihe, papanga, polymer linkable. hanga kaka kōata te i runga i te pūtake o ngā tapatapahi ranei muka me papanga whariki ranei.
3. rauemi Papa. E te aroaro ratou ki momo rerekē, me te zhidkovyazovyh tito paninga pukapuka e hāngai ana i runga i waerau. Kei te whānui te whare tono kahupeka i runga i te pūtake o pvc, ki pai ana te whakahaere mātao waiariki, me te oro. Ka taea te hanga tui o papa mastic i runga i te ranunga kai ki te oligomers.

Kirihou me ona tohu

E 5 ngā momo o kirihou, e whai ratou ti'araa:

1. Polyethylene terephthalate (kua te pukapuka tohu PET ranei Pete). Āhuatanga e kakama, me te tono whanui: whakamahia hoki te pupuri ngā inu, hinu, poke.
2. polyethylene High kiato (HDPE ranei tapaina rite PE HD). huru no te rauemi e pai, noho noa, ātete ki huringa pāmahana. whakamahia te reira mo te hanga o te hokona tuku, ipu mō peke rokiroki kai, taonga tākaro.
3. pūhaumāota Polyvinyl (pvc ranei tohua rite V). Mai i tenei rauemi he pūkete matapihi, wahi taonga, Film mo iri tuanui, putorino, nga kuaha, me te ake. No te mea te ihirangi o te bisphenol A, vinyl pūhaumāota, e kore e phthalates polyvinyl whakamahia i roto i te hanga o ngā hua (ipu, kanisā me te rite. P.) hoki te rokiroki kai.
4. Polyethylene (LDPE ranei māka PEBD). Tēnei rauemi iti-utu e whakamahia ana i roto i te hanga o peke, peke paru, kahupeka me ngā kōpae.
5. Polypropylene (PP he tapanga pūrārangi). kaha rerekē, wera resistance, e tika ana mo te hanga o ipu kai, tākai kai, taonga tākaro, pāhorehore.

momo Popular o te kirihou - terei me te polycarbonate. Kei te whakamahia whānuitia ratou i roto i ngā ahumahi.

Mara o te tono

Various momo o kirihou e whakamahia i roto i ngā ahumahi. I roto i tenei take, nga whakaritenga ki a ratou e pā ana ki te taua - humarie ana o mahi, me te haumaru. Kia whakaaro tatou nga momo o thermoplastics me ratou hōkai.

kirihou rewatau (tepu)

hei utu o te mutunga

I roto i te tuhinga nei ka titiro matou ki ngā momo o kirihou me ratou tono. A, no te whakamahi i enei rauemi whakaaro e āhuatanga maha, mai i te āhuatanga tinana, me te pūkaha me te āhuatanga oti te mahi. Ahakoa o tona kirihou utu he taumata rawaka o te haumaru, e tino faaaano te hōkai o tona tono.
