Ukusetshenziswa kwe-polyethylene wax ku-PVC

Ngomqondo omncane,i-polyethylene waxiyisisindo esiphansi samangqamuzana e-homopolymer polyethylene;Ngomqondo obanzi, i-polyethylene wax ihlanganisa i-polyethylene wax eguquliwe kanye ne-copolymerized.pe wax.Ngokuvamile, uma i-polyethylene polymer ingakwazi ukunikeza amandla athile kanye nokuqina njenge-resin, futhi ayikwazi ukucutshungulwa njengento eyodwa ibe umkhiqizo ekugcineni onomsebenzi othile, singawuhlukanisa njenge-polyethylene wax.

I-polyethylene wax isetshenziswa kakhulu kumapulasitiki njengesisabalalisi sombala, njengesithambisi semixube ye-PVC, njengesilungisi sokugeleza nesihambisanayo kuzilungisi ze-PE ne-PP.
Igama eliphelele le-PVC yi-PVC.Izinga lokushisa layo lokugeleza kwe-viscous lisondelene kakhulu nezinga lokushisa lokuwohloka, ngakho-ke kulula ukubhekana nezinhlobo ezihlukahlukene zokunciphisa ngesikhathi sokucubungula, okuholela ekulahlekelweni kokusebenziseka.
Ngakho-ke, iziqinisi zokushisa nezinto zokugcoba kufanele zengezwe ekwakhiweni kwezingxube ze-PVC, ezangaphambili zithuthukisa ukuzinza kwazo ezishisayo, lezi zokugcina zinciphisa ukungqubuzana phakathi kwamaketanga e-PVC wamangqamuzana, namandla okukhululwa kwefilimu phakathi kwe-PVC encibilika nensimbi, okwenza ngcono ukucubungula i-PVC. emikhiqizweni eyahlukene.I-polyethylene wax kanye ne-polyethylene oxidized wax izithambisi ezivamile ku-PVC.
Ngesikhathi sokucutshungulwa kwe-PVC, akukho ukuncibilika okuhlanzekile, izinhlayiya zesibili kuphela (100 μ Mayelana ne-m, ezihlanganisa izinhlayiya eziyinhloko nama-nodules) ngaphansi kwesenzo sokushisa nokugunda kwemishini, zihlukaniswe zibe amabhola amancane (1 μ M noma ngaphezulu), i inqubo yama-globules ehlukana futhi abe ama-nodule (100 nm).

Le nqubo ngokuvamile ibizwa ngokuthi i-gel noma i-plasticization.Ukuze kuzuzwe izakhiwo ezingcono zemishini, izakhiwo ezingaphezulu kanye nokucutshungulwa, izinga lejeli liphakathi kuka-70% no-85%.
Ukukhethwa okufanele kwe-wax ye-polyethylene kungabambezela noma kusheshise inqubo yejeli.Ngemva kokuncibilika, i-homopolymer polyethylene wax ikhona phakathi kwezinhlayiya eziyinhloko noma ama-nodule, ukunciphisa ukungqubuzana phakathi kwezinhlayiya eziyinhloko noma ama-nodule, ngaleyo ndlela kuncishiswe ukukhiqizwa kokushisa okungqubuzanayo kokuncibilika, ukubambezeleka kwe-PVC ye-PVC, nokuthuthukisa ukuzinza okushisayo kwe-PVC.
I-wax ye-polyethylene ene-oxidized inokuhambisana okuthile ne-PVC, enganamathisela ebusweni bamaqhuqhuva, ikhulise i-viscosity encibilikayo, futhi ikhuthaze kancane ukuziphatha kwejeli;
Omunye umsebenzi wayo oyinhloko ukwenza ifilimu ebusweni be-PVC encibilika nensimbi, ukunciphisa ukungqubuzana phakathi kwemishini yokuncibilika nokucubungula.Kuyi-ejenti ekhiphayo enhle ekucutshungulweni kwe-PVC, ikakhulukazi kumafilimu asobala we-PVC (organic tin stabilizer).Ukwengeza inani elifanele le-wax ye-polyethylene ene-oxidized akugcini nje ngokukhipha ukusebenza okuhle, kodwa futhi akunciphisi ukubonakala.
Njengamanje, ngaphezu kokwenziwa kwe-polyethylene wax kanye ne-polyethylene oxidized wax.I-wax kapharafini, i-Fischer Tropsch wax, kanye ne-wax yomkhiqizo nazo zisetshenziswa kakhulu ku-PVC, futhi zidinga ukufaniswa ngokuguquguqukayo ngokuya ngezinhlelo zokusebenza zokugcina.

Isibonelo, i-wax kapharafini esezingeni eliphansi ingadlala indima ekugcotshiseni kusenesikhathi, i-polyethylene wax esezingeni eliphakathi nendawo kanye ne-Fischer Tropsch wax ingabamba iqhaza ekugcobiseni okuphakathi nendawo, kanye ne-high melting point polyethylene wax ene-oxidized ingadlala indima ekugcobiseni sekwephuzile.
Amanye ama-lubricant anokumelana nezinga lokushisa okulinganiselwe, afana nopharafini nama-fatty acid esters, athambekele ekufakeni kuma-die heads emikhiqizo ye-extrusion kanye namarola okupholisa amafilimu e-calendering.Lezi zinto zingaba nemiphumela emibi ezindaweni ezingaphezulu zemikhiqizo yokugcina, kanye nendawo yokusebenza kanye nokukhiqizwa kwabasebenzi abasebenza endaweni.Ngaphezu kwalokho, ukuhambisana kwe-lubricant eyodwa ku-PVC kuphezulu kakhulu.Uma kusetshenziswa iphakethe le-lubricant elihlanganisiwe, izingxenye ezahlukahlukene azikwazi ukubekezelela futhi zisabelelane, okungaholela kalula ekucindezelweni.
Ngakho-ke, ukukhetha izinto zokugcoba ezinekhwalithi ezinzile kanye nokumelana okuhle kwezinga lokushisa okusekelwe ekusetshenzisweni komkhiqizo njengokuthi ukuphrinta nokufutha kuyadingeka yini kubaluleke kakhulu ekukhiqizeni okushelelayo kanye nokwenza ngcono ikhwalithi yomkhiqizo.
