Iimveliso zePVC ziye zadityaniswa ngokungenamthungo kuzo zonke iimbombo zobomi bethu bemihla ngemihla, ukusuka kwimibhobho ehambisa amanzi kumakhaya ethu ukuya kwizinto zokudlala ezimibalabala ezizisa ulonwabo ebantwaneni, kunye nokusuka kwimibhobho ebhetyebhetye kwizicwangciso zemizi-mveliso ukuya kwimigangatho enesitayile kumagumbi ethu okuhlala. Nangona kunjalo, emva kokusetyenziswa kwazo ngokubanzi kukho umbuzo: yintoni eyenza ezi mveliso zifezekise indibaniselwano egqibeleleyo yokuqhuba lula, inkangeleko enomtsalane, kunye nokusebenza ngamandla? Namhlanje, siza kutyhila izinto ezintathu eziphambili ezenza oku kwenzeke – i-ACR, iiplasticizers, kunye nezithambiso zangaphakathi.
I-ACR: IsiPhumo sokuPhuculwa kunye neNyuvesi yokuSebenza
I-ACR, okanye i-acrylic copolymer, sisongezo esibalulekileyo esidlala indima ebalulekileyo ekwandiseni iipropathi zokusetyenzwa kunye nokusebenza kweemveliso zePVC. Ngexesha lokucutshungulwa kwe-PVC, ukongezwa kwe-ACR kunokunciphisa ngokufanelekileyo i-viscosity yokunyibilika, ngaloo ndlela kuphuculwe umbane wezinto eziphathekayo. Oku akugcini nje ukwenza inkqubo yokucubungula ilula, ukunciphisa ukusetyenziswa kwamandla kunye nexesha lokuvelisa, kodwa kunceda ekuphuculeni amandla eempembelelo zeemveliso zokugqibela, zizenze zomelele ngakumbi ekusebenziseni okusebenzayo.
Xa i-PVC icutshungulwa kumaqondo okushisa aphezulu, iyancipha ukuthotywa kwe-thermal, enokuchaphazela umgangatho weemveliso. I-ACR inokusebenza njenge-stabilizer yokushisa ukuya kwinqanaba elithile, ukulibazisa ukuthotywa kwe-thermal ye-PVC kunye nokuqinisekisa ukuzinza kwezinto ngexesha lokucubungula. Ngapha koko, i-ACR inokuphucula ukugqitywa komphezulu weemveliso zePVC, izenze zibukeke zinomtsalane ngakumbi
Iiplastiki zePlastiki: Ukuguquguquka kunye noMboneleli wePlastiki
IiPlastiki lelinye icandelo eliphambili kwiimveliso zePVC, ikakhulu ezinoxanduva lokunyusa ukuguquguquka kunye neplastiki yePVC. I-PVC yipolymer eqinileyo kwimo yayo ecocekileyo, kwaye kunzima ukuyiqhuba kwiimveliso eziguquguqukayo. IiPlastiki zinokungena kwimixokelelwane ye-PVC yemolekyuli, inciphisa amandla e-intermolecular, ngaloo ndlela yenza ukuba izinto zibe bhetyebhetye.
Iindidi ezahlukeneyo zeplastiki zineempawu ezahlukeneyo kunye neemeko zesicelo. Umzekelo, iiplasticizers zephthalate zazikhe zasetyenziswa ngokubanzi ngenxa yesiphumo esihle seplastiki kunye nexabiso eliphantsi. Nangona kunjalo, ngokunyuka kogxininiso ekukhuselweni kwendalo kunye nempilo, iiplasticizers ezihambelana nokusingqongileyo ezifana ne-citric acid esters kunye ne-adipates ziye zaziwa kakhulu. Ezi plasticizers zinobuhlobo kokusingqongileyo azinanto intle yokwenza iplastikhi kuphela kodwa zikwakhawulelana nemigangatho engqongqo yokusingqongileyo kunye nokhuseleko, zizenza zilungele ukusetyenziswa kwipakethe yokutya, izixhobo zonyango, kunye neemveliso zabantwana.
Isixa seplastiki eyongeziweyo sinempembelelo ebalulekileyo kwiipropati zeemveliso zePVC. Ubungakanani obuphezulu bokongeza i-plasticizer iya kwenza iimveliso zibhetyebhetye ngakumbi kodwa zinokunciphisa amandla azo oomatshini. Ke ngoko, kwimveliso yokwenyani, uhlobo olufanelekileyo kunye nesixa seplasticizer kufuneka sikhethwe ngokweemfuno ezithile zeemveliso.
Izithambisi zangaphakathi: UPhuculwa oHambayo kunye nePolishi yoMphezulu·
Izithambisi zangaphakathi zibalulekile ekuphuculeni ukusetyenzwa kwe-PVC kunye nokuphucula iglosi yomphezulu weemveliso. Banokunciphisa ukungqubana phakathi kweeathomli zePVC, zenze ukuba izinto zihambe ngokulula ngakumbi ngexesha lokusetyenzwa, nto leyo ibaluleke ngakumbi kwiimveliso zePVC ezinobumba obuntsonkothileyo.
Ngethuba lokuxutywa kunye nokuqhutyelwa kwezinto ze-PVC, ii-lubricants zangaphakathi zinokunceda amacandelo ahlukeneyo adibanise ngokufanayo, ukuqinisekisa ukuhambelana komgangatho wemveliso. Ukongeza, banokuphinda banciphise ukunamathela phakathi kwezinto kunye nezixhobo zokulungisa, ukunciphisa ukunxiba kwesixhobo kunye nokwandisa ubomi baso benkonzo.
Ngaphezu koko, izithambiso zangaphakathi zinokuphucula isicwebezelisi somgangatho weemveliso zePVC, zizenze zibukeke zintle ngakumbi kwaye zikumgangatho ophezulu. Oku kubaluleke kakhulu kwiimveliso zePVC ezineemfuno eziphezulu zenkangeleko, ezinje ngeepaneli zokuhombisa kunye nezinto zokupakisha.
I-Synergy yeZitshixo eziThathu
I-ACR, iiplastiki, kunye nezinto zokuthambisa zangaphakathi azisebenzi ngokuzimeleyo; endaweni yoko, bayasebenzisana ukuze baqinisekise ukuba iimveliso zePVC zineempawu ezibalaseleyo zokucwangcisa, inkangeleko entle, kunye nokusebenza owomeleleyo
I-ACR iphucula ukusetyenzwa kwamanzi kunye namandla empembelelo, iiplastiki zibonelela ngokuguquguquka okuyimfuneko kunye neplastiki, kunye nezithambisi zangaphakathi zokwandisa ukuhamba komsebenzi kunye nokuphucula iglosi yomphezulu. Ngokudibeneyo, benza iimveliso zePVC ukuba zihlangabezane neemfuno ezahlukeneyo zezicelo ezahlukeneyo
Ukuqukumbela, i-ACR, iiplasticizers, kunye nezithambisi zangaphakathi zizitshixo ezintathu eziyimfuneko kwiimveliso zePVC '"ukusetyenzwa lula + ubuhle obuphezulu + ukusebenza okuqinileyo". Ngophuhliso oluqhubekayo lwethekhinoloji, ukusebenza kwezi zongezo kuya kuphuculwa ngakumbi, okuya kuqhuba inguqu eqhubekayo kunye nenkqubela phambili yoshishino lweemveliso zePVC, ukuzisa umgangatho ophezulu kunye neemveliso zePVC ezihlukeneyo ebomini bethu.
TopJoy Chemicalyinkampani egxile kuphando kunye nemveliso yePVC izinzisi ubushushukunye nezinyeizongezo zeplastiki. lt ngumnikezeli wenkonzo wehlabathi jikelelePVC eyongeziweyoizicelo.
