He momo hou te kiriuhi PE manawa-ā-wai o te rauemi polymer ā-wai. Mai i te tukanga hanga, he teitei ake ngā whakaritenga hangarau i ērā o ngā rauemi ā-wai whānui. I te wā kotahi, mai i te tirohanga kounga, he mahi anō hoki tā te kiriuhi manawa-ā-wai kāore i te whai āhuatanga o ētahi atu rauemi ā-wai.

He rauemi hou te kiriata PE e tere whanake ana i te ao. Ka kiia he kiriata manawa. He whānuitia te whakamahinga i roto i ngā momo mara nā ōna āhuatanga manawa me te ātete ki te uruhanga.

1. Te hanganga o te kiriuhi PE manawa
Ko te polyethylene te wāhanga matua o te kiriuhi PE e taea ai te manawa, he rauemi pūmua i hangaia mai i te polyethylene. I roto i te hanga polyethylene, ka tāpirihia he iti noa o te 4-waro, 8-waro rānei o te a-olefin hei comonomer. Heoi, nā te mea he iti noa te nui o te a-olefin e whakamahia ana, he maha ngā āhuatanga o te polyethylene e mau tonu ana.

He rauemi mā, he ware pi, he mārama te polyethene, he ngāwari, he uaua hoki, ā, ka taea te wehewehe ki te polyethylene iti-kiato (LDPE) me te polyethylene nui-kiato (HDPE).

Ka hangaia te LDPE mai i te ethylene i raro i te pēhanga teitei (98-250mpa), me te mātotoru o te 0.91-0.92g/m3. Ka hangaia te HDPE mai i te ethylene kua whakakotahitia i raro i te pēhanga 1.0mpa, me te mātotoru teitei ake, i ngā wāhi katoa 0.94-0.96g/m3.

Kāore he paitini o te polyethene, ā, he tino pai ngā āhuatanga dielectric. Ko tōna pāmahana whakawhiti karāhe he tata ki te -125℃. He tino pai te pumau matū o te polyethene, ka taea te ātete ki te waikawa me te kawakore i te pāmahana rūma, engari he ngāwari ki te waikura i te mārama me te wera, ā, ka taea hoki te pirau whakaahua i raro i te mārama ultraviolet. He tino pai hoki ngā āhuatanga miihini o te polyethene. Ka nui ake te kaha o te polyethylene i te wāhanga tioata, ā, ka pai te ngāwari o te wāhanga kore-kirita.

2. Ngā āhuatanga o te kiriuhi PE manawa
Ki te whakatauritea ki ngā kiriuhi kore-manawa, ko ngā āhuatanga o ngā kiriuhi PE manawa e whai ake nei:
1. Ka taea e ia te uru ki te hau engari kāore e uru ki te wai, nō reira ka taea te whakamahi hei rauemi ātete wai me te ātete ki te makuku;
2. Ka taea e ia te whakapai ake i te rere o te hau i roto i te taiao o te kaiwhakamahi, he mea pai ki te manawa o te kiri;
3. Nā ngā āhuatanga o ōna rauemi mata, he mea hou te kiriuhi PE, he rauemi pai mō te taiao, ā, kāore e whakapoke i te taiao.

3. Te rere o te tukanga o te kiriata PE manawa
Mai i te tirohanga hangarau tukatuka, e rua ngā tikanga tukatuka matua mō ngā kiriuhi manawa: ko te tikanga maka kiriata papatahi, ko tētahi ko te tikanga kiriata pupuhi, ā, ko te tikanga maka te mea e whakamahia whānuitia ana.
Ko te tukanga matua o te tikanga whakarewa koia tēnei:
Rauemi mata PE + te whakaranu porogen me te ine-whakaputa-whakapūtanga-whakaputa-whakatōtōtanga, te maka-totoru me te whakatakoto-whakamatao-kuti-takai.
I roto i te tukanga whakaputa kiriata manawa PET, he nui te awe o te tukanga totoro o te Raina Hanga Kiriata Manawa PE ki te mahi a te kiriata.
I te wā e totoro ana, ina iti iho te kaha here i waenga i ngā matūriki porogen caco3 me te pūmua PE e karapoti ana i te kaha whakarerekētanga o te pūmua PE i puta mai i te totoro, ka wehe te pūmua i ngā taha o te caco3, ka hua ake he matūriki ririki. Kāore e taea e ngā kōhao te tuku i ngā ngota wai kia haere, engari ko ngā ngota hau anake, kia mau ai te mahi a te kiriata totoro hei ārai wai me te manawa.
Ka taea te whakarite i te rahi o te kōhao i runga i ngā āhuatanga o te tukanga pēnei i te rahi, te āhua, te tikanga totoro, me te ōwehenga totoro o ngā matūriki caco3.
Ina eke te pāmahana totoro ki tētahi uara motuhake, ka piki ake te ōwehenga totoro, ka piki ake te whānui o te āputa o te kiriata manawa PE, ka piki ake te uruhanga o te hau, engari ka kino haere te mahi totoro; i te piki haere o te matotoru, ka heke te uruhanga o te hau.

4. Ngā raruraru me ngā ārai e tūpono pinepine ana i roto i te tukanga whakaputa kiriata PE manawa.

1 Kāore te matū i te kaha
He tino iti, he kore rānei te kaha o te kiriata PE manawa, ā, kāore e taea te whakatutuki i ngā hiahia o ngā kiritaki, ka mutu ka pakaru te hua. Nā te āhua motuhake o te tukanga hanga kiriata PE manawa, ka ngoikore pea ngā rauemi hanga, ka nui te ihirangi o ngā matū paheke, me te poke o te mata.
Te iti o te kukū o te mata
I raro i ngā āhuatanga noa, me neke ake te mātao o te mata o te kiriata PE manawa mō te whakaranu maroke i te 38 dyn/cm i mua i te whakamahinga.
Kua whakamātauhia e te mahi mēnā he iti iho te uara kukū o te mata o te kiriuhi PE manawa i te 38dyn/cm, ka puta pea te āhuatanga o te kaha hiato iti. Ki raro iho i te 36dyn/cm, ka tino iti, ka kore rānei te mana whakakotahi.
I te wā kotahi, e pā ana hoki te kaha o te rauemi whakakotahi ki te matotoru o te kiriata PE e āhei ana ki te manawa. Mena he iti iho i te 30 maikorona, ka taea te whakakotahi i te 36-38dyn/cm. Mena he 30-50 maikorona te matotoru, ā, ko te uara o te mānukanuka mata he 37dyn/cm, ka whakaarohia te hanganga rauemi whakakotahi. Pērā i te OPP/PE, ka taea e te pānga whakakotahi te whakatutuki i ngā whakaritenga. Engari ki te nui ake te matotoru i te 50 maikorona, kāore e taea te whakamahi mena he iti iho i te 38dyn/cm te matotoru.
Anei ētahi huinga raraunga hei tohutoro:
He tino nui te uara kume o te mata o te kiriuhi PE manawa i te wā e hangaia ana, engari i te roanga o te wā, ka heke haere te uara kume o te mata. I te nuinga o te wā, ka taea te penapena i te kiriuhi PE manawa mō te 3-6 marama, engari ka taea te penapena mō te 3-6 marama i te raumati. Ko te wā rokiroki i te wā makuku he pai ake kia kaua e neke atu i te rua marama.
Kua whakamātauhia e te mahi he tino tata te hononga o te uara kume o te mata o te kiriata PE ki tōna matotoru me te taiao e karapoti ana. Ka teitei ake te pāmahana me te haumākū o te taiao, ka tere ake te heke o te uara kume o te mata, ā, ka matotoru ake te kiriata, ka tere ake te heke.
Nō reira, kaua e neke atu i te toru marama te roa o te whakatakotoranga o te kiriata PE manawa, inā koa i te wā ua. Me aro nui atu ki te hauhautanga me te whakapūmau i te wāhi rokiroki mēnā he roa rawa te wā rokiroki mō tētahi take, ā, i te whakamahinga anō, hei tāpiri atu ki te tirotiro hurihuri-ki-te-roera, me whakaaro whānui mēnā ka whakamahia tonutia te hua whakakotahi kia rite ki te kaupapa o te hua whakaranu, kia kore ai e ngaro.

Te awe o ngā tāpiringa
Ina hangaia te kiriata manawa PE hei kiriata, me tāpiri ētahi tāpiringa, pēnei i ngā kaihoko ārai-pūmau, ngā kaihoko paheke, me ngā kaihoko ārai-pūmau, kia rite ki tōna whakamahinga.
Kāore ēnei tāpiringa e pumau i muri i te hanganga kiriata, i te whakakotahitanga rānei, inā koa ko ngā kaihoko paheke, e whakamahi ana i te erucamide, i te oleamide rānei.
E rua ngā take mō te hekenga o te kaha o te hiato nā ngā āputa paheke:
① I muri i te whakatakotoranga o te kiriata PE manawa mō te wā poto, ka heke te kaiāwhina paheke ki te mata o te kiriata PE manawa hei hanga i tētahi paparanga angiangi, matotoru. Ka ārai tēnei paparanga matotoru i te hononga o te piripiri me te āhua o te kiriata PE manawa, ka kore ai e taunekeneke te hononga ki te mata o te kiriata PE manawa. Ina pā te hononga o ngā ngota PE, he papaku te piri tuatahi o te hiato, i te mea ka roa te wā whakamaroke, kāore e tino rerekē te kaha whakakotahi, ā, ka noho tonu te kaha whakakotahi ki te iti, ki te kore rānei.
Me whakamahi he kiriata PE manawa-paheke-teitei mō ngā whakaritenga motuhake, ā, kaua e waiho mō te wā roa rawa i raro i ngā āhuatanga noa. Mena ka whakamahia te kiriuhi manawa PE mō tētahi wā roa mō tētahi take, he pai ake te whakanoho i te kiriuhi manawa PE ki te pāmahana o te 60-70℃ mō te neke atu i te 8 hāora i mua i te whakaranu. I tēnei wā, ka pakaru te ātete paheke, nō reira me mahi anō i tēnei wā. Kāore he raruraru o te kaha whakahiato iti i roto i te whakarārangi, engari kāore ngā āhuatanga paheke teitei o ngā kiriuhi manawa PE.
②E whakaaetia ana te piri tuatahi o te rauemi honohono, engari i te roanga o te wā whakamaroke, ka iti haere te kaha o te rauemi honohono, ā, ka puta he paura mā i waenganui i ngā paparanga e rua.
Nā te mea he nui ngā rauemi mata PE pahekeheke e whakamahia ana i roto i te hanga kiriata PE manawa. Nā te nui o te matū pahekeheke i roto i te kiriata, ka kaha ake te nekehanga o ngā ngota matū pahekeheke i roto i te kiriata i te wā e whakamarokehia ana i ngā pāmahana teitei (40-50℃). He nui ngā ngota matū pahekeheke e heke ana ki ngā taha e rua o te kiriata. I te roanga o te wā, ka piki haere te nui o te hekenga ki te mata. Ka whakangaromia e tōna hekenga te tukanga hononga ā-tinana i waenga i te piripiri me ngā ngota PE, ā, ka puta. Ka whakangaromia te kaha hononga ngoikore. Ka roa te wā, ka kaha ake te kaha whakangaro, ka iti ake te kaha whakakotahi.
I tēnei wā, ko te whakanui ake i te pāmahana whakamaroke te tikanga hei whakatere i te tere honohono o te piripiri kia nui ake ai te tere tauhohenga i te tere hekenga o te kaihoko paheke hei utu mō te nui rawa o te kaihoko paheke i roto i te kiriata PE manawa. Ngā pānga kino.

Te poke o te mata
Ko ngā kiriuhi PE e manawa ana, kāore i te poke i te nuinga o te wā i te wā e hangaia ana, engari ko tētahi o aua mea ka warewarehia: ko te poke o te wai dyne.
He maha ngā kaihanga kiriuhi PE e whakamahi ana i ngā otinga dyne kua whakaritea e rātou anō hei whakamātautau i te kukū o te mata o te kiriuhi. Ko te wai dyne he ranunga o te ethylene glycol monoethyl ether, he wai mārama, kāore he tae. Mēnā ka pokehia e te roera ārahi nā te puhoi o te tere o te mimiti, ka pakaru te kiriata ina haere mā roto i te roera ārahi. Ka uru te otinga dyne ki te mata o te kiriuhi PE, ā, ka piri tahi ki ngā ngota PE. Kāore e hono atu ki ngā ngota here i muri i te whakakotahitanga, ka hua ake he kaha whakakotahi ā-rohe o te kore. He uaua te kitea o tēnei āhuatanga i te tirotiro-mua.

2 ngā matū pūwāhi mā.
He māmā noa iho tēnei āhuatanga ki te puta i runga i te kiriata mā-kakara PE; i te nuinga o te wā, ka tāpirihia he nui o te matūriki mā ki te kiriata mā-kakara: te hauhā titanium kukū. Nā te rerekētanga o te kounga o te matūriki tae, he rerekē te rahi me te pakeke o te matūriki hauhā titanium kei roto, ka hua ake he rerekētanga o te kounga o te kiriata mā-kakara i hangaia i muri i te whakakotahitanga me te rerekētanga o te kanapa o te mata. Mena he taratara te mata o te kiriata mā-kakara, ā, he poka kei te taha, ka kitea he ira mā i te nuinga o ngā hua i whakakotahihia ki taua kiriata. Ko ngā otinga noa mō tēnei raruraru koia ēnei: ​​Ko te tuatahi ko te whakanui ake i te nui o te piri. Ko te tuarua ko te tā anō i tētahi paparanga waituhi mā. Ahakoa te tikanga e whakamahia ana, ka piki ake te utu, nō reira me tino tirotirohia te kiriata PE i mua i te whakamahinga.

3 I muri i te whakaranu, ka huri te hua kua oti hei kakano
Kua kitea tēnei āhuatanga i roto i te maha o ngā kaihanga. Kāore te mīhini tākai aunoa mō te hua hiato e oma pai ana, he uaua rānei te whakatuwhera i te putea i hangaia.
Ko te whakaranu maroke te tikanga he whakamahi i ngā piripiri tauhohe-rua-wāhanga, me whakamaroke i te pāmahana teitei i muri i te whakaranu kia eke ki te kaha o te ranunga teitei rawa atu. Ka rerekē te kaihopu paheke i roto i te kiriata PE manawa nā te huringa o te pāmahana whakamaroke. I tētahi pāmahana motuhake, ka rerekē te matū o te kaihopu paheke, ā, ka ngaro tōna pānga paheke. Ko te teitei ake o te rangi, ko te nui ake o te rerekētanga. Ko te nui ake o te ngaronga, ka noho te hua whakamutunga hei kakano, ā, kāore e taea te whakamahi.

Nō reira, me tino whakahaere te pāmahana o te rūma whakamaroke ki te 40℃, ā, kāore e taea te whakanui noa i te pāmahana. Waihoki, kia rite ki ngā whakamahinga rerekē o te hua, whiriwhiria ētahi atu kai hei karo i te kawa o te hua nā te kore e tika te whiriwhiri i ngā momo kapia.

4 Te hiri wera ngoikore
I muri i te whakaurunga o te matū, ka uru te tukatuka whakamutunga ki ngā ringa o te kaihoko, i ētahi wā ka tino teitei rawa te pāmahana hiri-wera ā-rohe, kāore i te tika te hiri-wera, me ētahi atu, kāore e taea te tiaki i ngā take kino. Ko ngā take mō tēnei hua ko te pakaru o te korona, te nui o te ihirangi o te matū paheke, me te nui rawa o te tāpiri o ngā rauemi hangarua.

Te pakaru o te korona
Ina pā te kiriata manawa PE mā roto i te roera tukunga ngaohiko teitei i te wā o te tukanga whakaputa, ka pakaru pea te kiriata i ngā take maha. He maha ngā wā ka puta he rīpene roa tēnei āhuatanga, ā, he pumau te tūranga. He tino teitei te uara o te kukū mata. Nā te mea ka hangaia e te uhi wera pakaru he matū me ngā rōpū porowhita pērā i te mata hiato, kāore e taea te hiri wera i tēnei matū. Nō reira, ka whakamahia i roto i te hanga putea, i te takai aunoa rānei. I puta he hiri wera hapa ngoikore. Ka tāpirihia e te kiriuhi manawa PE he uara kukū mata hiato i te wā e tomo ana ki te wheketere hei tirotiro hei karo i tēnei āhuatanga.

Te nui o te ihirangi o ngā kaihoko paheke
Nā te nui o te matū paheke i roto i te paparanga hiri wera o te kiriata PE manawa, ka nui te nui o taua matū ka tau ki runga i te mata o te kiriata PE manawa, ka hanga he paparanga matotoru, ka aukati i te hiri wera o te kiriata PE manawa.
Tērā pea ka puta tēnei mēnā ka whakamahia he kiriuhi PE kua pau te wā. Nō reira, me whiriwhiri ngā momo kapia e tika ana kia rite ki ngā hiahia motuhake a ngā kiritaki, ā, me ngana kia kaua e whakamahia he kiriata mate mō ngā hua pahekeheke. I muri i te puta o tēnei āhuatanga, me whakamahi he whakarewa hei muru i te taupoki wera i ngā wā katoa, ā, ka pai ake te pānga.

Te nui rawa o te tāpiritanga o ngā rauemi hangarua
Hei penapena utu, ka tāpirihia he nui o ngā rauemi hangarua ki te hanga o ngā kiriuhi PE manawa. Ko ngā rauemi hangarua ka whakahoutia i ngā pāmahana teitei, kaua e iti iho i te rua ngā wā. He nui ngā poke kei roto. I muri i te hanganga anō o te kiriuhi, ka tino pai ake te mahi hiri wera. Ka heke iho, ka piki ake te pāmahana hiri wera mā te 5-10℃. E whakaatu ana ngā whakamātautau, ina 30% te nui o te rauemi kua whakahokia mai mō te paparanga hiri wera, ka piki ake te pāmahana hiri wera o te kiriata manawa PE mā te 3-5℃. Ina 50% te nui o te tāpiri, ka piki ake te pāmahana hiri wera mā te 6-10℃, ā, me kaua e tāpirihia e te kaihanga kiriata ngā rauemi hangarua ki te paparanga hiri wera i ngā wā katoa e taea ana.

5. Awhe tono o te kiriuhi manawa PE
Nā te mea he ngohengohe, he whakamarie hoki ōna āhuatanga ā-tinana, ā-pūkaha hoki, he tino pai ngā āhuatanga kume me te whakaroa o te kiriuhi PE.
