3. Utshintsho lwePVC oluncinci lwenzuzo kunye nokukhethwa kweqhinga
Inzuzo kunye nokwakhiwa kuxoxwe yiPVC njengomzekelo.Isigaba sePVC sokuguqula indawo yemarike sisekelwe kwinqaku elikhankanywe ngasentla, kwaye "ixabiso + lomqhubi" logic ihlalutywa nge "valuation + driver" logic.Njengomgangatho wokulinganisa inzuzo, xa amashishini e-PVC ehlabathi langaphandle efikelela kwindawo ethile yenzuzo (1000 ngasentla), oko kuthetha ukuba inqanaba lenzuzo yonke yoshishino lilungile, elinokusetyenziswa njengoqikelelo oluphezulu, kunye noshishino. iqala ngokukhawuleza kodwa imfuno yimfuno.Kwi-off-season, i-inventory iqhutywe phantsi, kwaye emva kokubona phezulu, isetyenziswe njengomdlalo ongenanto owenziwe ngezigaba.Xa ilahleko zokudityaniswa kwe-chlorine-alkali, uninzi lwamashishini kushishino lunokulahlekelwa yimali njengoqikelelo oluphantsi.Ngeli xesha, umqhubi kufuneka athathelwe ingqalelo.Kwizinto ezisisiseko zePVC, imfuno iyaphuculwa ngokubanzi kwaye ukuhamba kuyakhawuleza.
Nangona kunjalo, kwinkqubo yokwenyani, ungadibana "noxabiso oluphantsi + umqhubi ukuya phezulu" ukuthelekisa ngaphezulu okanye "uxabiso oluphezulu + uqhube phantsi" ukuya kwixesha elihambelana nomoya.Inqaku elingasentla le-PVC ukusuka kwi-2016 ukuya kwi-2023 yayingumzekelo.Ukususela kwi-2016 kunye ne-2020-2021, ukunyuka kwe-dial-up-ups kwakungaphezulu kwi-macro-drives, kubandakanywa nokuphuculwa kwe-real estate industry ngo-2016, umgaqo-nkqubo wemali okhululekileyo ngo-2020, i-carbon neutralized ngo-2021. Ngexesha elifanayo Kwinqanaba , ingeniso yeshishini inyukile.Ukulahlekelwa kweshishini kuye kwanda ukususela ngoJuni 2022, kodwa phantsi kwenkxaso ye-alkaline-itshise inzuzo, ukwakhiwa kweshishini akubonakali, kwaye imfuno ithonywa yi-real estate.Ihlala ingabonakali, kwaye imarike iyaqhubeka ibuthathaka.Nangona ikwimeko ephantsi yoqingqo-maxabiso kodwa akukho kuqhuba, ixabiso lePVC belijikeleza kwinqanaba eliphantsi kulo nyaka.
Amaphepha ePvc angaphandle ePlastiki
Ukujonga kwiPVC yangoku, inzuzo yeenkampani zePVC eShandong ijikeleze -800.Ukusukela kwinyanga yeSilimela kulo nyaka uphelileyo, ibiphulukene nemali.Inzuzo edibeneyo ye-Shandong ijikeleze-200.Kulo nyaka, ibe kwimeko yelahleko encinci.Ngenxa yenzuzo yeendleko kunye nenzuzo kumntla-ntshona, ukunciphisa imveliso kumntla-ntshona akubonakali.Kwikota yokuqala yalo nyaka, bekukho iiseti ezitsha ze-2-3 zezixhobo ezitsha.Ukuveliswa kwezinto eziphezulu kuqhubekile kunyaka ophelileyo.Kwikota yokuqala, kusekho kwimo yokubonelela, ngoko nangona i-PVC ikwimeko ephantsi yokulinganisa ixabiso, ixabiso linzima ukwenza.Ukususela kumbono "wexabiso + lomqhubi", ixabiso eliphantsi liyimeko eyaneleyo yokuba ixabiso likhuphuke kwixesha elizayo kuneemeko eziyimfuneko.I-PVC yalo nyaka iqhutywa yimfuno.I-PVC yexesha elifutshane iya kuqhubeka ne-vibration trend ephantsi.Ngo-Epreli, ubukho bokugcinwa kwehlobo kunye nokufunwa kokulindela ukubuyisela, ngoko unokuzama ixabiso elincinci nangaphezulu kwixabiso langoku.
Shwankathela
Inzuzo iya kuchaphazela imodeli yokuziphatha yeshishini.Njengeshishini lemichiza, iinkampani ezinyukayo zixinene.Ngexesha elifutshane, utshintsho kwinzuzo kwixesha elifutshane luya kuchaphazela ukwakhiwa kwe-upstream.Inzuzo idluliselwa ekupheleni kwexabiso ngokuchaphazela unikezelo.Ukujonga emva kwimarike yembali ngengqiqo yesiqhelo "yokuvala+umqhubi", uqikelelo lwexabiso ludla ngokuba ziimeko ezaneleyo, kwaye uninzi lweempembelelo zokwenyani kwimarike ilele kumqhubi.I-rebound ibuyela ngokuqhelekileyo (umzekelo, iindleko zokulungiswa okubandayo ziphezulu, iglasi ayiyi kubanda xa iglasi ilahleka, kwaye icala lokubonelela aliyi kuncitshiswa ngokukhawuleza).Kwangaxeshanye, ishishini alinangeniso.Ixabiso lokuxabisa kukudibanisa izinto ezisisiseko zemveliso.Ngokomzekelo, phantsi kwexabiso eliphezulu leentlobo ezifana ne-PVC, ezantsi kuya kunciphisa ukuthenga iimpahla, kwaye i-alkali efana neglasi esezantsi iyadingeka nje.Imathiriyeli ekrwada ayinakumisa unikezelo.Ixesha lide).Ukongezelela, xa ugweba ixabiso, kufuneka ubeke ingqalelo kwinkqubo yemveliso.Ngokomzekelo, kwi-PVC, amandla okuvelisa iqoqo lombane langaphandle linomthamo omncinci wokuvelisa.Icala lokubonelela libangele impembelelo enkulu, kwaye imboni yokulahlekelwa kwenzuzo ye-chlorine -alkali amashishini adibeneyo aya kutshintsha.Xa ukhetha isicwangciso, ixabiso linokubhekiswa kwelinye leenketho.Kufuneka ngakumbi ukubona amandla omqhubi.Ukuthatha iPVC njengomzekelo, ixabiso langoku lamashishini amaninzi alizange libe phezulu phantsi kwelahleko yelahleko.Imfuno, kulindeleke ukunciphisa imveliso ngo-Epreli kunye nokunyuka kwemfuno.Ukususela kumbono wenzuzo kunye nelahleko kunombono wenzuzo kunye nelahleko, ixabiso elincinci linokuthi lihambelane nexabiso langoku.Gxininisa kwimeko yeendawo ekuyiwa kuzo kamva.umda.
