Muva nje, i-polyvinyl chloride (PVC), impahla ethatha isikhundla esibalulekile embonini yamakhemikhali, iphinde iba ukugxila embonini. Izitayela zentuthuko ekukhiqizweni kwazo, ekusetshenzisweni kwalo, ukusetshenziswa kwalo, kanye namandla ashukumisa emakethe adonsele ukunakwa okusabalele. Ngokusho kwemibiko yezemboni efanele, ohlangothini lokukhiqizwa, njengomunye wabakhiqizi abakhulu be-polyvinyl chloride emhlabeni, iChina ibone amabhizinisi amaningi amakhulu akhulisa ukutshalwa kwezimali kwawo futhi athuthukise ubuchwepheshe bayo ku-polyvinyl chloride ukukhiqizwa kokukhiqiza imigqa muva nje. UZhong'an, Jinan, uShandong Chemical Group umemezele ekuqaleni kwale nyanga ukuthi wawuqede ngempumelelo iphrojekthi yenguquko ehlakaniphile ye-polyvinyl chloride yokukhiqiza ukukhiqizwa kwayo. Ngokwethula amasistimu wokulawula okuzenzakalelayo athuthukile nemishini yokukhiqiza ephezulu, akukaze kuthuthukiswe kakhulu ukukhiqizwa kokukhiqiza, okukhuphuke okulindelekile kokukhipha okungama-30%, kodwa futhi kunciphise ukusetshenziswa kwamandla okungu-30%, ukuzungeza impumelelo yokungcola. Lesi sinyathelo sibuye sibuye sibonisa ukuhlola okusebenzayo kwamabhizinisi embonini yamanje ukwandisa amandla okukhiqiza kanye nokwandisa izinqubo zokukhiqiza, okuhlose ukwenza indawo enhle kakhulu emncintiswaneni wemakethe. Ensimini yesicelo, i-polyvinyl chloride, incike kwizakhiwo zayo ezinhle kakhulu ngokomzimba nangamakhemikhali, iyaqhubeka nokukhulisa insimu yayo yemakethe. Imboni yezokwakha ihlala iyindawo enkulu yokusebenzisa i-polyvinyl chloride, futhi isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zamapayipi, amaphrofayli, kanye nezinto zokwakha zokwakha. Ngenqubekela phambili eqhubekayo yokwakhiwa kwengqalasizinda kazwelonke kanye nokubuyiselwa kancane kancane kwemakethe yezakhiwo, isidingo semikhiqizo yePolyvinyl Chloride ikhombisa umkhuba wokukhula okuqinile. Isibonelo, kuphrojekthi yokwakha yesitimela esikhulu kunazo zonke yasemadolobheni esisedolobheni [igama ledolobha], lisetshenziselwa amandla amakhulu ama-polyvinyl chloride amapayipi ama-polyvinyl chloride, futhi isilinganiso sawo esihle sokuqina kanye nezilinganiso zokusebenza kwezindleko zamukelwa kakhulu ngohlangothi lwephrojekthi. Ngaphezu kwalokho, i-polyvinyl chloride iyavela futhi emikhakheni evelayo efana nezokwelapha nakwe-elekthronikhi. Embonini yezokwelapha, i-polyvinyl ye-polyvinyl yezokwelapha ephethwe ngokukhethekile isetshenziswa kabanzi ukukhiqiza amadivaysi ezokwelapha alahlekayo anjengezikhwama zokumnika, izikhwama zegazi kanye nama-catheters wezokwelapha. Ngoba kunokubonakala okuhle, ukuvumelana nezimo, kanye nokuqina, kunikeza lula ukusebenza kwezokwelapha futhi kuqinisekise ukuphepha kweziguli. Ensimini ye-elekthronikhi, i-polyvinyl chloride, njengezinto ezifaka izintambo zezintambo namakhebuli, ukuncika ekusebenzeni kwayo okuhle kogesi kanye nokuphikiswa kwamakhemikhali, kuqinisekisa ukusebenza kwezidingo zomkhakha wanamuhla we-elekthronikhi ngezinto ezisebenza kahle. Kodwa-ke, ukuthuthukiswa komkhakha we-polyvinyl chloride akuwona wonke uhambo olubushelelezi. Ngokuphikisana ne-wackrop yezidingo ezivikelekile zemvelo eziqinile, izinkinga zokuphuma kokungcola okufana ne-vinyl chloride monomer engakhiqizwa ngesikhathi sokukhiqiza i-polyvinyl chloride ingaphansi kwe-polyvinyl chloride ingaphansi kokuqashwa okuqinile. Ukuhlangabezana nale nselelo, izinhlangano zezimboni zihlela ngenkuthalo amabhizinisi ukuze afeze imisebenzi yokuvikelwa kwezobuchwepheshe kanye nokuqeqeshwa, aphathe ngokujulile izindlela ze-catalytic oxidation, ukuze aphathe kabi imfucuza yokukhiqiza ukuze aqinisekise ukuthi ukuphuma kwemfucuza kuhlangabezana namazinga. Ngasikhathi sinye, ezinye izifunda zethule nezinqubomgomo ezifanele zokuxhaswa kwezimboni, ukuhlinzeka ngezimali zoxhaso kanye nezintandokazi zentela kumabhizinisi asebenza ngenkuthalo ekuthuthukiseni okuvikelekile kwezemvelo, okuqondisa imboni yokuguqula ukuthuthuka okuluhlaza nangokuzinzile. Ngokuya ngemakethe, intengo ye-polyvinyl chloride iguquke ngezinga elithile muva nje. Ethintwa yizinto ezahlukahlukene njengokushintshashintsha kwamanani entengo kawoyela aphesheya, kanye nezinguquko ezifunwayo ezibonakalayo, kanye nezinguquko ekufuneni okuphansi, inani lePolyvinyl Chloride lithole inqubo yokuqala ekhuphukayo, bese liwa, bese lizinza ngenyanga edlule. Abahlaziyi bezimboni bakhombisa ukuthi yize kunokungaqiniseki emthanjeni wamanje, ngokuhamba kwesikhathi, ngokululama komnotho wembulunga yonke kanye nokwanda okuqhubekayo kwamasimu asafufusa, futhi kulindeleke ukuthi intengo ingahle ihlale isebenza ngaphakathi konyaka ofanele futhi ibonise umkhuba ophakeme ongaphezulu. Sekukonke, lapho ubhekene nawo womabili amathuba nezinselelo, imboni ye-polyvinyl chloride ilwela ukufeza ukuthuthuka okuphezulu okuphezulu ngezindlela ezahlukahlukene ezinjengokuvuka kwezobuchwepheshe, ukuthuthukiswa kohlelo lokusebenza. Akungabazeki ukuthi inkambiso yentuthuko yesikhathi esizayo izoba nomthelela omkhulu embonini yamakhemikhali kanye nezimboni ezakhiwe phansi ezakhiwe.
