I-Polyvinyl chloride (PVC), i-thermoplastic edumileyo, inobuthathaka obungabonakaliyo: idla ngokuwohloka ngexesha lokucubungula nokusetyenziswa. Kodwa ungoyiki! NgenaIziqinisi zePVC, amaqhawe angadunyiswanga kwihlabathi leplastiki. Ezi zongezo zibalulekile ekulawuleni ubuntu bePVC, zithintele ngempumelelo ukuwohloka kwaye zandise ubomi bayo. Kule posi yebhlog, singena nzulu kwihlabathi elinomtsalane lezinto ezizinzisayo zePVC, sihlola iintlobo zazo, iindlela zokusebenza, iindawo zokusetyenziswa, kunye neendlela ezinomdla ezibumba ikamva lazo.
I-PVC ayisiyonto nje iplastiki; yindawo enamandla eguquguqukayo. Ngeempawu zayo ezintle zoomatshini, ukumelana neekhemikhali okumangalisayo, ukufakelwa kombane okuphezulu, kunye nexabiso eliphantsi, i-PVC ifumene indlela yayo kwiimveliso ezingenakubalwa, ukusuka kulwakhiwo kunye nokupakisha ukuya ekuveliseni ucingo kunye neentambo kunye nezixhobo zonyango. Nangona kunjalo, kukho into ebambekayo. Ulwakhiwo lweemolekyuli ze-PVC lunee-athomu ze-chlorine ezingazinzanga, xa zichatshazelwa bubushushu, ukukhanya, okanye ioksijini, zibangela ukusabela kwetsheyini eyaziwa ngokuba yi-dehydrochlorination. Olu hlobo lokusabela lubangela ukuba izinto zitshintshe umbala, zilahlekelwe kukusebenza kwazo, kwaye ekugqibeleni zingasebenzi. Yiyo loo nto ukongeza izibambi ngexesha lokucubungula nokusetyenziswa kwe-PVC kungekuphela nje ukhetho—yinto efunekayo.
Iziqinisi zePVC zinokuhlulwahlulwa ngokweekhemikhali zazo zibe ziintlobo ezahlukeneyo.iintlobo:
IziQinisekisi zeTyuwa eziPhambili:Aba yayingoovulindlela kumdlalo we-PVC stabilizer, beqhayisa ngokuqina kobushushu kunye nokusebenza kakuhle kweendleko. Nangona kunjalo, ngenxa yeengxaki zabo zetyhefu, ziye zancitshiswa kancinci kancinci kwiminyaka yakutshanje.
Izinto Zokuzinzisa Isepha Yesinyithi:Eli qela liquka ezo zidumileyo ezifana ne-calcium-zinc kunye ne-barium-zinc stabilizers. Zibonelela ngozinzo oluhle lobushushu kunye nokuthambisa, nto leyo eyenza zibe zezona zisetyenziswa kakhulu namhlanje.
Izinto zokuzinzisa i-Organotin:Zidume ngokuqina kobushushu obugqwesileyo kunye nokungafihlisi nto, iziqinisi ze-organotin ziza nexabiso eliphezulu. Zisetyenziswa kakhulu kwiimveliso ze-PVC ezicacileyo.
Izinto Ezizinzileyo Zomhlaba Ongaqhelekanga:Njengabantwana abatsha kweli bhloko, ezi zigcina-manzi zinobuhlobo nokusingqongileyo zibonelela ngozinzo olukhulu lobushushu, azinabungozi, kwaye zibonelela ngokubonakala okuhle. Kodwa, njengezigcina-manzi ze-organotin, ziza ngexabiso eliphezulu.
Izinto Ezixhasayo Eziphilayo:Zodwa, ezi azinazo iimpawu zokuzinzisa. Kodwa xa zidityaniswe nezinye izinto zokuzinzisa, zisebenza ngomlingo wazo, ziphucula ukusebenza kakuhle kokuzinzisa. Imizekelo ibandakanya ii-phosphites kunye nee-epoxides.
Ngoko ke, ezi ziqinisi zisebenza njani kanye kanye umlingo wazo? Nazi iindlela eziphambili:
Ukufunxwa kwe-HCl:Izinzisi zisabela kwi-hydrogen chloride (HCl) eveliswa ngexesha lokuwohloka kwe-PVC, nto leyo ethintela isiphumo sayo sokuzilungisa.
Ukutshintshwa kwe-Atom yeChlorine engaguqukiyo:Ii-ion zesinyithi ezikwiziqinisi zithatha indawo yeeathom ze-chlorine ezingazinzanga kwimolekyuli ye-PVC, zinika ukomelela kozinzo lobushushu.
Isenzo se-Antioxidant:Ezinye izinto ezizinzisayo zineempawu ze-antioxidant, ezinceda ekuthinteleni ukuwohloka kwe-oxidative ye-PVC.
Izinto zokuqinisa i-PVC zikho kuyo yonke indawo kubomi bethu bemihla ngemihla, zidlala indima ebalulekileyo kwiintlobo ngeentlobo ze-PVCiimveliso:
Iimveliso zePVC eziqinileyo:Cinga ngeepayipi, iiprofayili, kunye namaphepha. Kwezi zinto, kusetyenziswa iziqinisi zetyuwa yelead, iziqinisi zesepha yesinyithi, kunye neziqinisi ze-rare earth.
Iimveliso zePVC eziguquguqukayo:Izinto ezifana neengcingo, iintambo, ulusu olungeyolwenziweyo, kunye neefilimu zixhomekeke kakhulu kwiziqinisi zesepha zesinyithi kunye neziqinisi ze-organotin.
Iimveliso zePVC ezicacileyo:Nokuba ziibhotile okanye amashiti, izinto ezigcina i-organotin ziyindlela efanelekileyo yokuqinisekisa ukucaca.
Njengoko ihlabathi lisiba nolwazelelelo ngakumbi ngokusingqongileyo kwaye itekhnoloji iqhubeka nokukhula, ikamva lezinto ezizinzisa iPVC liya lisiba nomtsalane.iindlela.
Ukuhamba Okuluhlaza:Ingqwalasela ikukuphuhlisa izinto ezizinzileyo ezingenabungozi, ezingenabungozi, nezibolayo, ezifana ne-calcium-zinc kunye nezinto ezizinzileyo zomhlaba ezingaqhelekanga.
Ukuphucula ukusebenza kakuhle:Kukho ugqozi lokwenza izinto ezizinzisayo ezisebenza ngcono ngezinto ezincinci, zinciphisa iindleko ngelixa zigcina ukusebenza okuphezulu.
Imisebenzi yokwandisa:Lindela ukubona izinto ezizinzisayo ezenza imisebenzi engaphezu komnye, njengokubonelela ngozinzo lobushushu kunye nokuthambisa okanye kwaneempawu ezichasene nokuma.
Amandla okuDityaniswa:Ukuxuba iintlobo ezahlukeneyo zezinto ezizinzisayo ukuze kudalwe iziphumo ezihambelanayo kunye nokufezekisa iziphumo ezingcono zokuzinzisa kuya kuba yinto eqhelekileyo.
Ngamafutshane, iziqinisi zePVC zingabagcini abathuleyo bePVC, ziqinisekisa ukuba isebenza kakuhle kwaye ihlala ixesha elide. Ngemithetho engqongqo yokusingqongileyo kunye nophuhliso oluqhubekayo lwetekhnoloji, ikamva lilelezi ziqinisi zePVC ezinobuhlobo nokusingqongileyo, ezisebenzayo, ezisebenza ngeendlela ezininzi, nezidibeneyo. Hlala ujonge ezi zinto zintsha—ziza kuguqula ihlabathi leplastiki!
