Muva nje, i-polyvinyl chloride (PVC), into ephethe isikhundla esibalulekile embonini yamakhemikhali, iphinde yaba yinto ebalulekile embonini. Izitayela zokuthuthukiswa ekukhiqizweni kwayo, ekusetshenzisweni kwayo, kanye nasekushintsheni kwemakethe zidonsele ukunaka kabanzi. Ngokusho kwemibiko efanele yemboni, ohlangothini lokukhiqiza, njengomunye wabakhiqizi abakhulu be-polyvinyl chloride emhlabeni, iShayina ibone amabhizinisi amaningi amakhulu amakhemikhali ekhulisa njalo ukutshalwa kwezimali kwawo futhi ithuthukisa ubuchwepheshe bawo emigqeni yokukhiqiza ye-polyvinyl chloride muva nje. I-Zhong'an, eJinan, Shandong Chemical Group imemezele ekuqaleni kwale nyanga ukuthi iqede ngempumelelo iphrojekthi yokuguqula ehlakaniphile ye-workshop yayo yokukhiqiza i-polyvinyl chloride. Ngokwethula izinhlelo zokulawula ezizenzakalelayo ezithuthukisiwe kanye nemishini yokukhiqiza esebenza kahle, ayithuthukisanga nje kuphela ukusebenza kahle kokukhiqiza, ngokunyuka okulindelekile komkhiqizo waminyaka yonke okungu-30%, kodwa futhi inciphise ngempumelelo ukusetshenziswa kwamandla kanye nokukhishwa kokungcola, ifinyelela intuthuko entsha ekukhiqizweni okuluhlaza. Lesi sinyathelo siphinde sibonise ukuhlola okusebenzayo kwamabhizinisi embonini yamanje ukwandisa amandla okukhiqiza nokwenza ngcono izinqubo zokukhiqiza, kuhloswe ukuba nesikhundla esihle kakhulu emncintiswaneni wemakethe oqhubeka ukhula ngamandla. Ensimini yokufaka isicelo, i-polyvinyl chloride, ethembele ezimpahleni zayo ezinhle kakhulu zomzimba nezamakhemikhali, iyaqhubeka nokwandisa indawo yayo yemakethe. Imboni yokwakha isalokhu iyindawo enkulu kakhulu yokusetshenziswa kwe-polyvinyl chloride, futhi isetshenziswa kabanzi ezinhlotsheni ezahlukene zamapayipi, amaphrofayili, kanye nezinto zokuhlobisa izakhiwo. Ngokuthuthuka okuqhubekayo kokwakhiwa kwengqalasizinda kazwelonke kanye nokubuyiselwa kancane kancane kwemakethe yezindlu, isidingo semikhiqizo ye-polyvinyl chloride sibonisa ukuthambekela kokukhula okuqhubekayo. Isibonelo, kuphrojekthi yokwakha izitimela zasemadolobheni enkulu yakamuva e-[City Name], inani elikhulu lamapayipi e-polyvinyl chloride anamandla aphezulu futhi alwa nokuguga asetshenziswa ezinhlelweni zokuphakelwa kwamanzi kanye nokuthuthwa kwamanzi, futhi ukuqina kwawo okuhle kakhulu kanye nesilinganiso sokusebenza kwezindleko kwaqashelwa kakhulu ohlangothini lwephrojekthi. Ngaphezu kwalokho, i-polyvinyl chloride nayo iyavela emikhakheni ekhulayo njengezokwelapha neze-elekthronikhi. Embonini yezokwelapha, i-polyvinyl chloride elashwe ngokukhethekile yezokwelapha isetshenziswa kabanzi ukukhiqiza amadivayisi ezokwelapha alahlwayo njengezikhwama zokufaka, izikhwama zegazi, kanye nama-catheter ezokwelapha. Ngenxa yokuthi inokucaca okuhle, ukuguquguquka, kanye nokuhambisana kwezinto eziphilayo, inikeza lula imisebenzi yezokwelapha futhi iqinisekisa ukuphepha kweziguli. Emkhakheni we-elekthronikhi, i-polyvinyl chloride, njengento yokuvikela izintambo nezintambo, ethembele ekusebenzeni kwayo okuhle kokuvikela ugesi kanye nokumelana nokugqwala kwamakhemikhali, iqinisekisa ukusebenza okuzinzile kwamadivayisi kagesi, ihlangabezana nezidingo zemboni yesimanje ye-elekthronikhi yezinto ezisebenza kahle. Kodwa-ke, ukuthuthukiswa kwemboni ye-polyvinyl chloride akuhambisani kahle. Ngokuphikisana nezidingo zokuvikela imvelo eziqinile, izinkinga zokukhishwa kwezinto ezingcolisayo njenge-vinyl chloride monomer engase ikhiqizwe ngesikhathi senqubo yokukhiqiza i-polyvinyl chloride zingaphansi kokubhekwa okuqinile. Ukuze kuhlangatshezwane nale nselele, izinhlangano zezimboni zihlela ngenkuthalo amabhizinisi ukuthi enze imisebenzi yokushintshana nokuqeqeshwa kobuchwepheshe bokuvikela imvelo, akhuthaze amabhizinisi ukuthi amukele ubuchwepheshe bokukhiqiza obuhlanzekile obuthuthukisiwe, njengezindlela ze-gas-phase catalytic oxidation, ukuze aphathe ngokujulile igesi engcolile ukuqinisekisa ukuthi ukukhishwa kwezinto ezingcolisayo kuyahlangabezana nezindinganiso. Ngesikhathi esifanayo, ezinye izifunda nazo zethule izinqubomgomo zokusekela izimboni ezifanele, zihlinzeka ngezimali kanye nezintandokazi zentela kumabhizinisi enza ngenkuthalo ukuthuthukiswa kokuvikelwa kwemvelo, eqondisa imboni ukuthi iguqukele ekuthuthukisweni okuluhlaza nokusimeme. Ngokuphathelene nemakethe, intengo ye-polyvinyl chloride iye yashintsha ngezinga elithile muva nje. Ithintwe yizici ezahlukahlukene ezifana nokushintshashintsha kwamanani kawoyela ongahluziwe wamazwe ngamazwe, izimo zokuhlinzekwa kwezinto zokusetshenziswa, kanye nezinguquko ekufuneni okuzayo, intengo yesikhathi esizayo ye-polyvinyl chloride ibhekane nenqubo yokwenyuka kokuqala, bese yehla, bese izinzile ngenyanga edlule. Abahlaziyi bezimboni bakhomba ukuthi yize kukhona ukungaqiniseki endleleni yamanje yamanani, ngokuhamba kwesikhathi, ngokululama komnotho womhlaba kanye nokwanda okuqhubekayo kwamasimu okusetshenziswa avelayo, amathuba emakethe ye-polyvinyl chloride asebanzi kakhulu, futhi kulindeleke ukuthi intengo cishe izohlala izinzile ngaphakathi kobubanzi obufanele futhi ibonise ukuthambekela okuphakathi kokukhuphuka phakathi nonyaka olandelayo. Sekukonke, lapho ibhekene namathuba nezinselele, imboni ye-polyvinyl chloride ilwela ukufeza intuthuko yayo yekhwalithi ephezulu ngezinyathelo ezahlukahlukene ezifana nokusungula izinto ezintsha kwezobuchwepheshe, ukunwetshwa kokusetshenziswa, kanye nokuthuthukiswa kokuvikelwa kwemvelo. Ukuthambekela kwayo kwentuthuko yesikhathi esizayo ngokungangabazeki kuzoba nomthelela omkhulu embonini yamakhemikhali kanye nezimboni ezihlobene nayo ezizayo.
