Ngengqiqo emxinwa,polyethylene waxisihlobo esisezantsi sobunzima bemolekyuli homopolymer polyethylene;Ngengqiqo ebanzi, i-wax ye-polyethylene ikwabandakanya i-wax elungisiweyo ye-polyethylene kunye ne-copolymerizedpe wax.Ngokuqhelekileyo, ukuba i-polyethylene polymer ayikwazi ukunika amandla athile kunye nokuqina njenge-resin, kwaye ayikwazi ukucutshungulwa njengento enye kwimveliso ekugqibeleni inomsebenzi othile, sinokuyihlula njenge-wax ye-polyethylene.
I-wax ye-polyethylene isetyenziswa ngokubanzi kwiiplastiki njenge-dispersant ye-pigments, njenge-lubricant ye-PVC blends, njenge-flow modifier kunye ne-compatibilizer kwi-PE kunye ne-PP modifiers.
Igama elipheleleyo lePVC yiPVC.Iqondo lokushisa lokuhamba kwe-viscous lisondele kakhulu kwiqondo lokushisa lokuthotywa, ngoko kulula ukufumana iindlela ezahlukeneyo zokuthotywa ngexesha lokucutshungulwa, okukhokelela ekulahlekelweni kokusebenziseka.
Ke ngoko, izizinzisi zobushushu kunye nezithambiso kufuneka zongezwe kuyilo lwemixube yePVC, eyeyangaphambili iphucula uzinzo lwe-thermal, le yokugqibela inciphisa ukungqubana phakathi kwamatyathanga emolekyuli yePVC, kunye nefilimu yokukhupha ifilimu phakathi kwe-PVC enyibilikayo kunye nesinyithi, ukuphucula ukusebenziseka lula kwePVC. kwiimveliso ezahlukeneyo.Iwax yePolyethylene kunye nepolyethylene oxidized wax zizithambisi eziqhelekileyo kwiPVC.
Ngexesha lokucutshungulwa kwe-PVC, akukho kunyibilika okucocekileyo, kuphela iincinci zesibini (100 μ Malunga ne-m, equkethe iinqununu eziphambili kunye namaqhuqhuva) phantsi kwesenzo sokushisa kunye ne-mechanical shear, yahlula kwiibhola ezincinci (1 μ M okanye kunjalo), i inkqubo yeeglowubhu ezahlula kwakhona zibe ngamaqhuqhuva (100 nm).
Le nkqubo ibizwa ngokuba yi-gel okanye iplastiki.Ukuze ufezekise iipropati ezingcono zomatshini, iipropati zomhlaba kunye nokuqhubekeka, iqondo le-gel liphakathi kwe-70% kunye ne-85%.
Ukukhethwa okufanelekileyo kwe-wax ye-polyethylene kunokulibazisa okanye ukukhawuleza inkqubo ye-gel.Emva kokunyibilika, i-homopolymer polyethylene wax ikhona phakathi kweenqununu eziphambili okanye amaqhuqhuva, ukunciphisa ukungqubuzana phakathi kweenqununu eziphambili okanye amaqhuqhuva, ngaloo ndlela kuncitshiswe ukuveliswa kobushushu obuxubeneyo bokunyibilika, ukulibazisa iplastiki yePVC, kunye nokuphucula ukuzinza kwe-thermal ye-PVC.
I-wax ye-polyethylene ene-oxidized ine-compatibility ethile kunye ne-PVC, enokuthi ifake kumphezulu wamaqhuqhuva, ikhulise i-viscosity enyibilikayo, kwaye ikhuthaze kancinci ukuziphatha kwejeli;
Omnye umsebenzi wayo oyintloko kukwenza ifilimu ebusweni be-PVC inyibilika kunye nesinyithi, ukunciphisa ukungqubuzana phakathi kokunyibilika kunye nezixhobo zokusebenza.Yi-arhente yokukhululwa kakuhle kwi-PVC processing, ngakumbi kwi-PVC ecacileyo (i-organic tin stabilizer) iifilimu.Ukongeza isixa esifanelekileyo se-wax ye-polyethylene ene-oxid ayinayo kuphela ukusebenza kakuhle kokukhululwa, kodwa ayinciphisi ukungafihli.
Okwangoku, ngaphezu kokwenziwa kwe-polyethylene wax kunye ne-polyethylene oxidized wax.I-wax yeparafini, i-wax ye-Fischer Tropsch, kunye ne-wax yemveliso nazo zisetyenziswa ngokubanzi kwi-PVC, kwaye kufuneka zihambelane ngokuguquguqukayo ngokwezicelo ze-terminal.
Umzekelo, indawo ephantsi yokunyibilika iwax yeparafini inokudlala indima ekuthanjisweni kwangaphambili, indawo ephakathi yokunyibilika i-polyethylene wax kunye neFischer Tropsch wax inokudlala indima ekuthambiseni okuphakathi, kunye nenqanaba lokunyibilika eliphezulu eline-oxidized polyethylene wax inokudlala indima ekuthambiseni kade.
Ezinye izithambiso ezinokumelana nobushushu obulinganiselweyo, njengeparafini kunye ne-fatty acid esters, zithande ukudipozithwa kwiintloko zeemveliso ze-extrusion kunye neeroli zokupholisa zeefilimu zekhalenda.Ezi zinto zinokuba nemiphumo emibi kwiipropati zomphezulu weemveliso zokugqibela, kunye nendawo yokusebenza kunye nokuveliswa kwabasebenzi bendawo.Ngaphezu koko, ukuhambelana kwe-lubricant enye kwi-PVC kuphezulu kakhulu.Ukuba iphakheji ye-lubricant edibeneyo isetyenzisiweyo, amacandelo ahlukeneyo awakwazi ukunyamezela kunye nokusabelana, nto leyo inokukhokelela ngokulula kuxinzelelo.
Ke ngoko, ukukhetha izithambiso ezinomgangatho ozinzileyo kunye nokumelana nobushushu obusekwe kwimveliso yemveliso efana nokuba ukuprinta kunye nokutshiza kuyafuneka kubaluleke kakhulu kwimveliso egudileyo kunye nokuphucula umgangatho wemveliso.
