I-Pendahuluan
Amakhebula ayisici esibalulekile cishe kuzo zonke izinhlelo zesimanje: kusukela ezinhlelweni zikagesi zasekhaya kuya kumanethiwekhi okuxhumana, izinhlelo zezimoto, ngisho nengqalasizinda yamandla avuselelekayo. Naphezu komsebenzi wawo obonakala ulula—ukuqhuba ugesi noma ukudlulisa izimpawu—amakhebula anethonya elikhulu emvelweni, ngokuvamile enziwa ngethusi noma i-aluminium kanye nezinhlobo ezahlukene zepulasitiki ezifana ne-PVC ne-PE zokuvikela nokuvikela ijakhethi. Njengoba isidingo somhlaba wonke samakhebula sanda, kuphakama umbuzo obalulekile: imboni ingahlangabezana kanjani nalesi sidingo ngaphandle kokwenza kube kubi kakhulu ukukhiqizwa kwemfucuza kanye nokuxhashazwa kwezinsiza? Impendulo eyodwa ubuchwepheshe bokukhiqiza amakhebula asetshenziswe kabusha, indlela ehlanganisa ubunjiniyela bezinto, izinqubo zokukhiqiza, kanye nezinhlelo zekhwalithi ukuqinisekisa ukuthi amakhebula ahlala ephephile, ethembekile, futhi ehlangabezana nezindinganiso, ngisho nalapho izinto zokusetshenziswa zitholakala kumfucuza.
Kungani Izinto Ezisetshenziswe Kabusha Zibalulekile Embonini Yezintambo
Kunemithombo emibili eyinhloko yemiphumela yezemvelo ezintanjeni: izinsimbi zomqhubi kanye nama-polymer okufaka ugesi. Ukumba ithusi kanye ne-bauxite (ye-aluminium) kudinga amandla amakhulu futhi kunamandla okulimaza imvelo. Okwamanje, amapulasitiki okufaka ugesi angaphathwanga kahle angagcina esezindaweni zokulahla udoti noma engcolise imvelo. Ngokusebenzisa ukuphinda kusetshenziswe, imboni inganciphisa isidingo sezinto zokusetshenziswa ezingavuthiwe, inciphise ukukhishwa kwekhabhoni kusuka kuchungechunge lokuhlinzeka, futhi yandise umjikelezo wokuphila wezinto zokwakha. Ngaphandle kwezici zemvelo, ukusetshenziswa kwezinto eziphinde zasetshenziswa nakho kunenani lezomnotho ngoba kuzinzisa izindleko zezinto zokusetshenziswa ngezikhathi zokushintshashintsha kwamanani ensimbi nepulasitiki emakethe yomhlaba wonke.
Imithombo Yezinto Ezisetshenziswe Kabusha Zezintambo
Izinto eziphinde zasetshenziswa zokukhiqiza izintambo ngokuvamile zivela ku:
1. Izingcezu zekhebula ngemuva kokusebenzisa: izintambo ezisetshenzisiwe ezivela ezakhiweni, ezimotweni, kumadivayisi kagesi, noma engqalasizinda endala.
2. Izinsalela zezimboni (ezenziwe ngaphambilini): imfucuza yokukhiqiza njengezingcezu zomqhubi, imfucuza yepulasitiki ephumayo, noma imikhiqizo enephutha engacutshungulwa kabusha.
3. Imfucuza kagesi (imfucuza kagesi): amadivayisi kagesi aqukethe izintambo zangaphakathi kanye nezingxenye zensimbi eziyigugu.
4. Amapulasitiki asetshenziswa ngemva kokusetshenziswa: ama-polymer afana ne-PE noma i-PP avela kweminye imikhiqizo eyahlukahlukene abese eguqulwa ukuze asetshenziswe ngokukhethekile kwi-cable jacket.
Le mithombo iyahlukahluka ngekhwalithi. Izinsalela zezimboni zivame ukuhlanzeka futhi zihambisana, kuyilapho izinsalela zangemuva kokuthengwa ziguquguquka kakhulu futhi zidinga ubuchwepheshe bokucubungula obuqinile ukuze kuhlangatshezwane nezidingo zekhebula.
Ubuchwepheshe Bokuvuselela Insimbi Yomqhubi (Ithusi Ne-Aluminium)
Umqhubi uyinhliziyo yekhebula. Ukuze kugcinwe umqhubi nokuphepha, ithusi noma i-aluminium esetshenzisiwe kumele ibe msulwa kakhulu. Ubuchwepheshe bokubuyisela buhlanganisa:
1. Ukuhlukaniswa Kwangaphambi Kokuqala Nokuhlanza
Izintambo ezisetshenzisiwe zihlungwa kuqala ngohlobo (lukagesi, idatha, i-coaxial) kanye nokuqukethwe kwensimbi (ithusi noma i-aluminium). Okulandelayo, ziyasuswa (kususwe ijazi/ukufakwa komoya) ngomshini noma kusetshenziswa i-granulator.
2. Ukwehlukaniswa kanye nokuhlukaniswa
Izintambo ezisikiwe zaba yizicucu ezincane bese zicutshungulwa kusetshenziswa inhlanganisela yalokhu okulandelayo:

Umphumela walesi sigaba uba ama-granule ethusi noma e-aluminium aqukethe ukungcola okucindezelwe.
3. Ukuncibilikisa Nokucwenga
Ukuze kufezwe ikhwalithi yomqhubi, izinsimbi zivame ukudlula enkambisweni yokuncibilikisa esithandweni esikhethekile, kulandelwe ukucwengwa. Ngethusi, inqubo yokucwengwa ingafaka:
– Ukucwengisisa umlilo ukuze kuncishiswe ukungcola okuthile.
– Ukuhlanza ngogesi (ezindaweni ezithile) kukhiqiza ithusi elisezingeni eliphezulu kakhulu elisondela kuthusi we-cathode.
I-aluminium ephinde yasetshenziswa ingancibilikiswa futhi ihlinzwe ngokususwa kwegesi kanye nokuhlunga ukuze kuncishiswe ukuminyana kanye nokuvuleka.
4. Ukwakha Izintambo (Ukudweba Izintambo)
Insimbi ecwengekile yenziwa izinduku, bese idonswa ocingweni kusetshenziswa umshini wokudonsa ucingo, idlula lapho iyafa ngezigaba kuze kube yilapho kufinyelelwa ububanzi obufunekayo. Le nqubo idinga ukulawulwa ngokucophelela kokuthambisa, izinga lokushisa, kanye nokucindezeleka kokudonsa ukuze kuvinjelwe ucingo ukuthi lungaqhekeki futhi lugcine ukuguquguquka.
Ubuchwepheshe Bokuvuselela I-Polymer Bokufaka Izintambo Nokufaka Ijakethi
I-insulation/ijakethi yekhebula ngokuvamile yenziwe nge-PVC, PE, XLPE, noma ingxube ye-elastomer. Inselele iwukuthi i-polymer kumele ihlangabezane nezakhiwo zikagesi nezemishini: ukumelana namandla kagesi, ukumelana nokushisa, ukuguquguquka, kanye nokumelana nokuguga.
1. Ukuhlunga Ngokusekelwe Ohlotsheni Lwe-Polymer
Amapulasitiki avela ekususeni izintambo ngokuvamile ayingxube—isibonelo, i-PVC evela ejazini, i-PE evela ekushiseni okuthile, kanye nokungcola okunamathelayo noma okuyinki. Ngenxa yokuthi i-polymer ngayinye inezici ezihlukile, ubuchwepheshe bokuhlunga bubalulekile, isibonelo:
– Ukuhlunga okuseduze kwe-Infrared (NIR) ukuze kutholakale izinhlobo zepulasitiki.
– Ukuhlukaniswa kobuningi (isinki yokuntanta) okusebenzisa umehluko ekubuneni kwe-polymer.
2. Ukugeza Nokuhlanza
Izinto ezingcolisayo njengothuli, uwoyela, noma izinsalela zensimbi kudingeka zisuswe ngokuwasha ngamakhemikhali okwenziwa ngomshini nangokulula. Lesi sinyathelo sinquma ikhwalithi yama-pellet asetshenziswe kabusha, ikakhulukazi ekusetshenzisweni kokushisa okudinga ukuhlanzeka kwezinto ukuze kuvinjelwe ubuthakathaka be-dielectric.
3. Ukuhlanganiswa kabusha kanye nokwengezwa kwezithasiselo
Ama-polymer asetshenziswe kabusha awavamile ukusetshenziswa "njengoba enjalo." Ngokuvamile ahlanganiswa ku-extruder ukuze kuthuthukiswe ukusebenza, isibonelo yi:
– Isiqinisi sokushisa (esibalulekile kwi-PVC).
– Isivimbeli somlilo sokwakha izintambo.
– Isiqinisi se-Antioxidant kanye ne-UV sokusetshenziswa ngaphandle.
– I-Plasticizer yokwandisa ukuguquguquka kwe-PVC.
Kulesi sigaba, abakhiqizi bangaxuba i-resin emsulwa ne-resin ephinde yasetshenziswa ngezilinganiso ezithile ukuqinisekisa ukuthi ikhebula lihlangabezana nezindinganiso.
4. Ukufakwa Kwezinto Zokushisa Nokushisa Ijazi
Uma sekufakwe i-pellet, izinto ziyakhishwa kusetshenziswa i-extruder yekhebula. Amapharamitha anjengokushisa kwebhareli, isivinini sesikulufu, kanye nokupholisa kumele alawulwe ngokuqinile ukuze kuvinjelwe amabhamuza, izikhala, noma ubukhulu obungalingani obungalimaza ikhwalithi yokufakwa kwe-insulation.
Izindinganiso Zokulawula Ikhwalithi Nokuphepha
Amakhebula ayimikhiqizo yokuphepha. Ngakho-ke, ukusetshenziswa kwezinto eziphinde zasetshenziswa kumele kuqinisekiswe ngokuhlolwa. Ezinye izivivinyo ezibalulekile zifaka:
- Ukuhlolwa kokumelana komqhubi ukuqinisekisa ukuthi umqhubi ungaphakathi kwezidingo.
– Ukuhlolwa kokumelana ne-dielectric/i-hi-pot kokuvikela ukushisa.
– Ukuhlolwa kokufakwa kokushisa kanye nobukhulu bejakethi, kanye nokuhlolwa kokukhubazeka kwendawo.
– Ukuhlolwa kokuthamba nokwelula ukuqinisekisa ukuguquguquka kanye namandla omshini.
– Ukuhlolwa kokuguga kokushisa kanye nokuhlolwa kokumelana nomlilo (kuye ngokuthi kujwayelekile futhi kusetshenziswe kanjani).
Ngaphezu kwalokho, ukusebenzisa uhlelo lokulandelela kubalulekile ukulandelela inqwaba ngayinye yezinto ezisetshenzisiwe emthonjeni kanye nemingcele yazo. Abakhiqizi abaningi basebenzisa nezindinganiso zekhwalithi kanye nokuphathwa kwemvelo njenge-ISO 9001 kanye ne-ISO 14001.
Izinselele Eziyinhloko Ekukhiqizweni Kwezintambo Ezisetshenziswe Kabusha
Nakuba amathuba ekhona enkulu, kunezinselele ezithile zangempela:
