Te hangarua anō i ngā putea whatu PP

Nā te whānui o te whakamahinga o ngā putea whatu kirihou PP, kua piki ake te rahinga whakaputa oNgā putea whatu PPKei te piki haere, ā, ka piki ake te nui o ngā putea para. He huarahi whai hua te hangarua i ēnei putea para hei whakaiti i ngā utu whakaputa, hei tiaki i te taiao, hei whakamahi katoa hoki i ngā rauemi. I ngā tau tata nei, he maha ngā kaihanga kua rangahau i tēnei wāhanga.

 

Ka arotahi tēnei kōrero ki te hangarua oNgā putea whatu PPKo ngā para e pā ana ki ngā para kirihou PP e tika ana mō te whakaputaNgā putea whatu PPHe tikanga whakamahi para momo kotahi tēnei, he nui ngā whakaritenga; kāore e taea te whakaranu ki ētahi atu momo kirihou, ā, kāore hoki e taea te whakauru i te paru, te onepu, ngā poke, ngā poke ā-ringa rānei. Me noho tōna taupū rere rewa ki roto i te awhe 2-5 (ehara i te mea he pai ngā kirihou PP katoa). E rua ngā pūtake matua: ngā para mai i te tukanga hanga putea whatu PP me ngā para putea PP hangarua, pērā i ngā putea tongi, ngā putea whāngai kararehe, ngā putea tote, me ētahi atu.

 

2. Ngā Tikanga Whakamahi Anō

 

E rua ngā tikanga hangarua matua: te whakakorikori i te kirikiri whakarewa me te whakakorikori i te kirikiri, ko te whakakorikori i te kirikiri te mea tino noa. Ko ngā tukanga mō ngā tikanga e rua e whai ake nei.

 

2.1 Tikanga Whakarewa Rewa

 

Para -- te whiriwhiri me te horoi -- te whakamaroke -- te tapahi kia porotaka -- te whakapūkara tere-rahi (whāngai -- te whakaiti wera -- te rehu wai -- te whakapūkara) Te tukunga me te takai.

2.2 Tikanga Whakapūtanga Whakaputa

 

Para -- kōwhiringa -- horoi -- whakamaroke -- tapatapahia kia porotaka -- whakaputanga wera -- whakamatao me te whakapūpū -- tākai.

 

Ko ngā taputapu e whakamahia ana i roto i te tikanga whakaputanga he mīhini whakaputanga e rua ngā wāhanga i hangaia e ia anō. Hei tango i te hau i puta mai i te whakaputanga o ngā rauemi para, ka taea hoki te whakamahi i tētahi mīhini whakaputanga hau. Hei tango i ngā paru mai i ngā rauemi para, me whakamahi he mata mata 80-120 i te pito tukunga o te mīhini whakaputanga. Kei te ripanga ngā tikanga tukanga mō te whakaputanga hangarua.

 

Me whakahaere tika te pāmahana o te mīhini whakaputa, kaua e tino teitei, kaua hoki e tino iti. Ka tere te pakeketanga me te kōwhai o te rauemi i te pāmahana nui rawa, ka huri rānei hei waro, ka mangu hoki, ka pā kino ki te kaha me te āhua o te kirihou; ki te kore e ranea te pāmahana, ka ngoikore te kirihou, ka iti te tere whakaputa, ka kore rānei he rauemi e puta, ā, he tino ngāwari ki te kino te mata tātari. Me whakatau te pāmahana whakaputa hangarua tika i runga i ngā hua o te taupū rere rewa o ia puranga para hangarua i tangohia me te whakamatautauria.

 

3. Te Whakamahinga o ngā Rauemi Hangarua me ō rātou Pānga ki te Mahi a te Pēke PP: Ko te koroheketanga wera i te wā tukatuka kirihou he pānga nui ki te mahi, inā koa mō ngā pēke PP whatu hangarua kua rua, neke atu rānei ngā tukanga wera. I te taha o te koroheketanga UV i te wā e whakamahia ana i mua i te hangarua, ka tino heke te mahi. Nō reira,Ngā putea whatu PPkāore e taea te whakamahi anō mō ​​ake tonu atu. Mena ka whakamahia ngā rauemi hangarua anake hei hanga putea PP, e toru noa iho ngā wā ka taea te hangarua. Nā te mea he uaua ki te whakatau i te maha o ngā wā i tukatukahia ai ngā para hangarua, kia pai ai te kounga o te putea PP, ahakoa mō ngā putea he iti ake ngā whakaritenga, me whakamahi he ranunga o ngā rauemi tauhou me ngā rauemi hangarua i roto i te hanga. Me whakatau te ōwehenga o te ranunga i runga i ngā raraunga ine tuturu o ngā rauemi e rua. Ko te nui o te rauemi hangarua e whakamahia ana ka pā tika ki te kounga o te miro papatahi putea PP. Ko te kounga o ngā putea whatu e whakawhirinaki ana ki te kaha kume me te roa o ngā miro papatahi. E tohu ana te paerewa ā-motu (GB8946-88) i te kaha o te miro papatahi >=0.03 N/denier me te roa o te 15%-30%. Nō reira, i roto i te hanga, tata ki te 40% o ngā rauemi hangarua ka tāpirihia. I runga i te kounga o te rauemi hangarua, ka taea te whakanui ake i tēnei ki te 50%-60%. Ahakoa ka whakaitihia ngā utu hanga mā te tāpiri atu i ngā rauemi hangarua, ka whakararu i te kounga o te putea. Nō reira, me tika te nui o te rauemi hangarua i tāpirihia, kia pai ai te kounga. 4. Ngā whakarerekētanga ki te tukanga tuhi i runga i te whakamahinga o ngā rauemi hangarua: Nā te tukatuka wera me te koroheketanga UV i te wā roa o te whakamahinga, ka piki ake te taupū rewa o te PP hangarua i ia huringa tukatuka. Nō reira, ina tāpirihia he nui o ngā rauemi hangarua ki te rauemi hou, me whakaiti tika te pāmahana o te extruder, te pāmahana o te pane mate, me te pāmahana totoro me te tautuhinga ki te rauemi hou. Me whakatau te nui o te whakarerekētanga mā te whakamātautau i te taupū rewa o te ranunga rauemi hou me te rauemi hangarua. I tetahi atu taha, nā te mea he maha ngā taahiraa tukatuka o ngā rauemi hangarua, ka heke te taumaha ngota, ka hua ake he maha o ngā mekameka ngota poto, ā, kua maha hoki ngā tukanga totoro me te whakatakotoranga. Nō reira, i roto i te tukanga whakaputa, me iti ake te ōwehenga totoro i tērā o te momo rauemi hou. I te nuinga o te wā, ko te ōwehenga totoro o te rauemi hou he 4-5 ngā wā, i muri i te tāpiri i te 40% o ngā rauemi hangarua, he 3-4 ngā wā. Waihoki, nā te pikinga o te taupū rewa o te rauemi hangarua, ka heke te matotoru, ka piki ake te tere o te extrusion. Nō reira, i raro i ngā āhuatanga tere me te pāmahana o te tīwiri, me tere ake te tere o te tuhi. I te whakaranu i ngā rauemi mata hou me ngā rauemi mata tawhito, he mea nui kia ōrite te whakaranu; i te wā anō, me whiriwhiri ngā rauemi mata he rite ngā tohu rewa hei whakaranu. Ko te rerekētanga nui o ngā tohu rewa me ngā pāmahana rewa, ko te tikanga kāore e taea te whakakirihou i ngā rauemi mata e rua i te wā kotahi i te wā e whakakirihou ana, ka pā kino tēnei ki te tere totoro o te whakakirihou, ka hua ake he tere para nui, ka kore rānei e taea te whakaputa.

 

E ai ki te kōrero i runga ake nei, ko te hangarua me te whakamahi anō i ngā meaPPwhatungā puteaKa taea te whakatutuki mā te whiriwhiri rauemi tupato, te whakatakotoranga tukanga tika, me te whakahaere tika i ngā āhuatanga tukanga. Kāore e pā ki te kounga o te hua, ā, he tino nui ngā painga ōhanga.
