Rauemi tākai whakapaipai mātauranga-pēke kanohi kanohi

Ngā Kaupapa Matua mō te Whakahaere Hanga o ngā Pēke Tākai Kōpare Kanohi

Te matotoru o te putea kiriata:tikanga 100 maikorona-160 maikorona,ko te matotoru o te pepa konumohe parakore mō te whakamahinga hiato he mea noa iho7 maikorona

Te whakaputangate wā ārahi: e tumanakohia ana kia tata ki te 12 ngā rā

Aruminiumukiriata:He rauemi takai ngāwari hiato te VMPET, he mea hanga mā te whakakikorua i tētahi paparanga angiangi rawa o te konumohe whakarewa ki runga i te mata o tētahi kiriata kirihou mā te whakamahi i tētahi tukanga motuhake. Ko te painga he pānga kanapa whakarewa, engari ko te ngoikoretanga he āhuatanga ārai ngoikore.

1. Tukanga Tā

Mai i ngā whakaritenga o te mākete o nāianei me te tirohanga a te kaihoko, ko ngā kopare kanohi he hua tino pai te kounga, nō reira he rerekē ngā whakaritenga whakapaipai taketake i ngā whakaritenga kai noa me ngā takai matū o ia rā, he "tino pai" te hinengaro kaihoko. Nō reira, mō te tānga, hei tauira, ko te tika o te tānga me ngā whakaritenga tae o tana tānga he iti rawa te taumata teitei ake i ngā whakaritenga takai kē atu. Mena ko te paerewa ā-motu ko te tika o te tānga matua he 0.2mm, ko ngā tūranga tuarua o te tānga putea takai kopare kanohi me tutuki i tēnei paerewa tānga kia pai ake ai te urutau ki ngā whakaritenga a te kiritaki me ngā hiahia o te kiritaki.

Mō ngā rerekētanga tae, he tino pakari ake, he tino taipitopito ake hoki ngā kaihoko mō ngā takai kopare kanohi i ngā kamupene kai noa.

Nō reira, i roto i te tukanga tā, me aro nui ngā kamupene e hanga ana i ngā takai kopare kanohi ki te whakahaere i te tā me te tae. Heoi anō, ka nui ake ngā whakaritenga mō ngā papa tā kia urutau ki ngā paerewa teitei o te tā.

2.Te tukanga whakarārangi

E toru ngā āhuatanga matua e whakahaeretia ana e te hiato: ngā kita hiato, ngā toenga whakarewa hiato, ngā poka me ngā mirumiru hiato me ētahi atu āhuatanga rerekē. I roto i tēnei tukanga, ko ēnei āhuatanga e toru ngā mea matua e pā ana ki te hua o ngā putea tākai kopare kanohi.

(1) Ngā kita whakakotahi

E kitea ana i te hanganga o runga ake nei, ko te nuinga o ngā putea tākai kopare kanohi he whakakotahitanga o te konumohe parakore. Ka hurihia te konumohe parakore mai i te konganuku parakore ki roto i tētahi rau kiriata angiangi rawa, e mōhiotia whānuitia ana ko te "kiriata konumohe" i roto i te umanga. Ko te matotoru kei waenganui i te 6.5 me te 7 μm. Heoi anō, he matotoru ake anō hoki ngā kiriata konumohe.

He tino ngāwari te kiriuhi, te pakaru, te poka rānei o ngā kiriata konumohe parakore i te wā e whakakīia ana. Ina koa mō ngā mīhini whakakīia e hono aunoa ana i ngā rauemi, nā te koretake o te hononga aunoa o te matua pepa, he ngāwari te kore taurite, ā, he tino ngāwari hoki te kiriuhi o te kiriata konumohe i muri tonu i te whakakīia, te mate rānei.

Mō ngā kita, i tētahi taha, ka taea e tātou te whakatika i muri i te tukanga hei whakaiti i ngā ngaronga i puta mai i ngā kita. Ina pumau te kāpia whakakotahi ki tētahi āhua, ko te huri anō tētahi huarahi, engari he huarahi noa iho tēnei hei whakaiti; i tētahi atu taha, ka taea e tātou te tīmata mai i te pūtake. Whakaitihia te nui o te takai. Ki te whakamahi koe i tētahi matua pepa nui ake, ka pai ake te pānga takai.

(2) Ngā toenga whakarewa whakakotahi

I te mea he konumohe parakore, he konumohe whakarewa rānei kei roto i ngā takai kopare kanohi, mō ngā mea whakakotahi, he kino te noho o te konumohe whakarewa, te konumohe parakore rānei ki te whakapūpū o ngā whakarewa. Nā te mea he kaha ake ngā āhuatanga ārai o ēnei mea e rua i ētahi atu rauemi whānui, nō reira he kino ki te whakapūpū o ngā whakarewa. Ahakoa kua mārama te kī i roto i te paerewa GB/T10004-2008 "Dry Computing Extrusion Compound of Plastic Composite Films and Bags for Packaging": Kāore tēnei paerewa e pā ki ngā kiriata kirihou me ngā putea i hangaia ki ngā rauemi kirihou me te turanga pepa, ki te pepa konumohe rānei.

Heoi, i tēnei wā, e whakamahia ana hoki e ngā kamupene tākai kopare kanohi me te nuinga o ngā kamupene tēnei paerewa ā-motu hei paerewa. Mō ngā putea pepa konumohe, e hiahiatia ana hoki tēnei paerewa, nō reira he āhua hē.

Kāore i te mārama ngā whakaritenga o te paerewa ā-motu, engari me whakahaere tonu e tātou ngā toenga whakarewa i roto i te hanga tuturu. Heoi anō, he tino wāhi whakahaere nui tēnei.

E ai ki ōku ake wheako, he mea tika kia whakapai ake i te whiriwhiringa o te kāpia, te tere o te mīhini whakaputa, te pāmahana o te oumu, me te nui o te putanga hau o ngā taputapu. Me tātari, me whakapai ake hoki i ngā taputapu me ngā taiao motuhake mō tēnei āhuatanga.

(3) Te whakapūpū me ngā mirumiru

Ko tēnei raruraru e pā ana ki te konumohe parakore, inā koa he hanganga PET/AL hiato, he nui ake te tūponotanga ka puta. Ka kohia e te mata hiato he maha ngā āhuatanga "ira karaihe", he āhuatanga "mirumiru" rānei. Ko ngā take matua ko:

Mō te rauemi turanga: Kāore i te pai te maimoatanga o te mata o te rauemi turanga, ka ngawari ki te pakaru me te mirumiru; he nui rawa ngā ira tioata o te rauemi turanga PE, ā, he nui rawa hoki, he tino take hoki tēnei o ngā raruraru. I tētahi atu taha, ko te āhua matūriki o te waituhi tētahi o ngā take. Ko ngā āhuatanga taurite o te kāpia me ngā matūriki taratara o te waituhi ka puta anō hoki ngā raruraru rite i te wā e piri ana.

Hei tāpiri atu ki tēnā, mō te whakahaere o te mīhini, ina kore te whakarewa e mimiti rawaka, ā, kāore hoki te pēhanga whakaranu i te teitei rawaka, ka puta anō hoki ēnei āhuatanga rite, kua purua te roera mata whakapiri, he mea ke rānei kei roto.

Rapua ngā otinga pai ake mai i ngā āhuatanga o runga ake nei, ka aromatawai, ka whakakore rānei i aua mea i runga i te huarahi whai kiko.

3. Te hanga putea

I te pūwāhi whakahaere o te tukanga hua kua oti, ka tirohia e mātou te papatahi o te putea me te kaha me te āhua o te hiri taha.

I roto i te tukanga hanga putea kua oti, he uaua ki te mārama ki te maeneene me te āhua. Nā te mea ko tōna taumata hangarau whakamutunga ka whakatauhia e te mahi a te mīhini, ngā taputapu, me ngā tikanga mahi a ngā kaimahi, he tino ngāwari te waru i ngā putea i te wā o te tukanga hua kua oti, ā, ka puta pea ngā āhuatanga rerekē pēnei i ngā taha nui me ngā taha iti.

Kāore rawa e whakaaetia ēnei mō ngā putea kopare kanohi he tino uaua ngā whakaritenga. Hei whakaoti i tēnei raruraru, me whakahaere te mīhini mai i te taha 5S tino taketake hei whakahaere i te āhuatanga rakuraku.

Hei te whakahaere taiao awheawhe taketake rawa atu, ko te horoi i te mīhini tētahi o ngā tino taurangi whakaputa hei whakarite kia ma te mīhini, kia kore ai he mea ke e puta mai i runga i te mīhini, kia pai ai te mahi. Me whakarerekē hoki i ngā whakaritenga me ngā tikanga whakahaere taketake me ngā tikanga motuhake o te mīhini.

Mō te āhua, mō ngā whakaritenga hiri taha me te kaha hiri taha, ko te tikanga me whakamahi he maripi hiri he kiko pai ake, he maripi hiri papatahi rānei hei pēhi i te hiri taha. He tono motuhake tēnei. He whakamātautau nui hoki tēnei mā ngā kaiwhakahaere mīhini.
