Izitsha ezine ezigcwele i-resin ye-PVC-SG5 esezingeni eliphezulu evela ku-Aojin Chemical zithunyelwe eSaudi Arabia.

(I) Umkhakha Wokwakha kanye Nengqalasizinda: "Izinto Ezibalulekile" Zamaphrojekthi Engqalasizinda
Njengesimo esiyinhloko sokusetshenziswa kwe-PVC-SG5, umkhakha wokwakha nengqalasizinda ubangela isidingo esingaphezu kuka-60%, ofaneleka kakhulu ezindaweni ezishisa kakhulu nezigqwala kakhulu zaseMpumalanga Ephakathi, njenge-Saudi Arabia:
Ukukhiqizwa Kwamapayipi Nokufakwa: Lesi yisiqondiso esiyinhloko sesicelo se-PVC-SG5. Ngezinqubo zokukhipha, ingakhiqiza amapayipi okuphakelwa kwamanzi nawokukhipha amanzi, amapayipi okwelapha indle, amapayipi okunisela ezolimo, kanye namapayipi okuvikela amandla nokuxhumana. Ngezinzuzo zayo zokumelana nokugqwala, izindonga zangaphakathi ezibushelelezi ezingakhuli, kanye nokumelana okunamandla kwengcindezi, isibe yinto ekhethwayo yengqalasizinda kamasipala, ukwakhiwa kwezindlu zokuhlala, kanye namaphrojekthi okunisela asehlane. Isibonelo, uhlelo lokuvuselela imithombo yamanzi lwe-NEOM Future City yaseSaudi Arabia kanye nenethiwekhi yokuphakelwa kwamanzi nokukhipha amanzi yephrojekthi yezokuvakasha yoLwandle Olubomvu zombili zisebenzisa kakhulu amapayipi e-PVC-SG5. Amaphrofayili namaphaneli omnyango namafasitela: Ngemva kokwenziwa ngcono kwefomula, amaphrofayili e-PVC (ozimele bomnyango namafasitela, ukubumba okuhlotshisiwe), amabhodi e-foam, ophahleni, njll., angakhiqizwa. Le mikhiqizo ilula, kulula ukuyifaka, futhi imelana nokuguga, ifanele isimo sezulu esibi kakhulu sezindawo zasehlane, kuyilapho ibiza ama-60% kuphela e-aluminium alloys, okwenza kube ukukhetha okujwayelekile kwezakhiwo zokuhlala nezentengiselwano. Izinto zokuvimbela amanzi nokuvala: Ngemva kokuhlanganiswa nama-plasticizers kanye nama-stabilizers, ama-membrane angangeni manzi kanye nemichilo yokuvala ingenziwa ukuze kuvikelwe uphahla kanye nokuvala amapayipi. Ukumelana kwazo nesimo sezulu kungahlangabezana nezidingo zendawo yaseSaudi Arabia enokushisa okuphezulu kanye nelanga iminyaka engaphezu kwengu-50.

(II) Umkhakha Wokukhiqiza Izimboni: Izixazululo Ezenziwe Ngokwezifiso Zezimo Ezikhethekile Ngokusebenzisa ubuchwepheshe bokuguqula, i-PVC-SG5 ingashintshwa ukuze ivumelane nezidingo ezikhethekile zemikhakha yezimboni, ikakhulukazi ephumelela kakhulu ekumelaneni nesimo sezulu, ekubambeni ilangabi, kanye nezakhiwo ezivimbela ukuguquka: Ukusekelwa Kwemboni Yezimayini Namakhemikhali: Ngemva kokuguqulwa ngokufakwa kwezithiba zomlilo (i-antimony trioxide), ama-antistatic agents (i-conductive carbon black), kanye nama-toughening agents (MBS/CPE), ingasetshenziswa ukukhiqiza amapayipi okungenisa umoya emayini kanye namapayipi okuhambisa amakhemikhali. Lawa mapayipi amelana nokugqwala kwamakhemikhali e-acid kanye ne-alkali futhi anezakhiwo ezivimbela ukuguquka kanye nezivimbela ukuguquka, ahlangabezana nezidingo zokuphepha zezindawo ezinobungozi obukhulu. Izinto Zokufaka Ukushisa Ngogesi: Ngokusebenzisa izakhiwo zayo ezinhle kakhulu zokufaka ukufudumala ngogesi, ingasetshenziswa ukukhiqiza imikhono yokuvikela ikhebula, amateyipu okufaka ukufudumala, amaphaneli okushintsha, njll. Emaphrojekthini wamandla kagesi kanye namandla avuselelekayo aseSaudi Arabia, isetshenziselwa ukuvikela nokufaka ukufudumala kwezintambo zekhebula, futhi ukumelana kwayo nokushisa okuphezulu kuyivumela ukuthi isebenze ezindaweni ezingaphezu kuka-60°C. Izingxenye Zezimoto Nezomshini: Ukubumba ngomjovo kusetshenziselwa ukukhiqiza amasondo okuqondisa izimoto, izibambo zamathuluzi, izivalo, izindawo zokugcina amadeshibhodi, njll. Le mikhiqizo iqinile kakhulu, ayigugi, futhi inokuhamba okuhle kokucubungula, okuvumela ukubumba kwesakhiwo esiyinkimbinkimbi okukodwa, ngaleyo ndlela kuhlangatshezwane nezidingo zokukhiqiza ezinkulu zokukhiqiza izimoto.
