PVC External Lubricant: Musiyano pakati peFischer Wax nePE Wax

Polyethylene wakisi, inozivikanwawo sepolymer wax, inoshandiswa zvakanyanya nekuda kwekunaka kwayo kutonhora, kuramba kupisa, makemikari kuramba, uye kusapfeka.Mukugadzirwa kwakajairwa, wakisi iyi inogona kuwedzerwa zvakananga ku polyolefin kugadzirisa sechinhu chinowedzera, icho chinogona kuwedzera kupenya nekugadzirisa kushanda kwechigadzirwa.Sekuzora, ine yakagadzikana makemikari zvinhu uye yakanaka magetsi emagetsi.Kuenzaniswa nePVC uye mamwe ekunze ekuzora, polyethylene wakisi ine yakasimba yemukati lubrication maitiro.

Fischer Tropsch wakisiinonyanya kuumbwa nemutsara, yakazadzwa yakakwira kabhoni alkanes ine huremu hwemamorekuru pakati pe500 ne1000, iyo inopa kemikari iyi ine yakanaka kristaro chimiro, yakakwirira kunyungudika, nhete yekunyungudika, yakaderera mafuta emukati, yakaderera kupinda, yakaderera kufamba, yakaderera kunyungudika. viscosity, kuoma, kupfeka kuramba, uye kugadzikana kwepamusoro.

Musiyano wakakosha pakati peFischer Tropsch wax synthetic wax uye general polyethylene wax ndewekuti:
(1) Huremu hwemorekuru.Huremu hwema molecular yeFischer Tropsch wax yakadzikira zvakanyanya pane yePE wax, ine macheni mashoma ane matavi uye yakakwirira crystallinity.Zviri nyore kupinda mukati mepamusoro viscosity macromolecular cheni, zvakanyanya kuderedza kunyungudika viscosity.Iyo ine yakaderera kutama panguva yekugadzirisa uye yakajeka lubrication maitiro mune inotevera nhanho.
(2) Fischer Tropsch wax is saturated yakananga yakabatana alkane iyo isina ma bond maviri, ine yakasimba antioxidant kugona, uye chigadzirwa chine kunaka kwemamiriro ekunze.

(3) Viscosity yeFischer Tropsch wax yakadzikira zvakanyanya pane yePE wax.Chete kutenderedza 10. Mari diki inogona kuwana yakafanana lubrication maitiro.Iko kushandiswa kunongova 70-80% yePE wakisi.Fischer Tropsch wakisi ine kuenderana kwakanaka nePVC uye inogona kushandiswa sesese emukati nekunze mafuta ekuzora.Inogona kushandiswa semafuta akanaka emukati kuti anyatso kudzora mamiriro ekugera, kukurudzira kuyerera, kudzora friction uye kunyunguduka zvinhu, nekudaro kuvandudza kupisa kugadzikana.Panguva imwecheteyo, nekuda kwehupamhi hwekristaro uye yakakwirira mutsara chimiro, Fischer Tropsch wax inogonesa zvigadzirwa zvePVC kuwana zvakanakisa zvemuviri uye kugadzirisa zvivakwa.Zvinoenderana nezvinodiwa, iyo Fischer Tropsch maitiro anogona kusanganisa alkanes nehurefu hwakasiyana cheni kushandura huremu hwemamorekuru echigadzirwa chekupedzisira uye kugadzira nhevedzano yezvigadzirwa.

Iyo huru nzira yekuita kwekunze kwemafuta
Kazhinji, mafuta ekunze ePVC inzvimbo yakakwira yekunyunguduka isina polarity kana yakaderera polarity, yakakwira kunyungudika inosvika 50-200 ℃, uye huremu hwakakura.
Iyo nzira yekuita ndeyekushandisa kusapindirana kwayo kugadzira chigadziko chekuzora kunze kwepamusoro pePVC inonyungudika kana kuyerera unit, inovandudza kukweshera pakati penzvimbo yezviyero zvekuyerera uye pakati pekunyungudika nesimbi.Zviri nyore kunaya patembiricha yepamusoro, asi hazvisi nyore kunaya patembiricha yekamuri.

Mhedzisiro yemafuta pane zvigadzirwa
Mafuta ekunze, kuisa purasitiki kubva pakutsanya kuenda kunonokesa, kuita kwechigadzirwa kubva kumusoro kusvika pasi, uye kuyerera kubva muhurombo kuenda kune yakanaka kune kusagadzikana.
Padanho rekutanga rekugadzirisa extrusion, kana resin zvimedu zvichitsvedza kukweshana, nzvimbo yekunyunguduka yekuzora kwekunze yakakwira uye hapana kunyungudika, izvo zvisingazononotse kugadzika kwepurasitiki.Pakati uye gare gare nhanho dzekugadzirisa, tembiricha yekunyunguduka inowedzera, uye iyo yakanyungudutswa yekunze lubricant inovhara pakati pekunyunguduka, zvakakodzera kunonoka purasitiki uye kunatsiridza kunamatira nesimbi, kudzivirira yakanyanyisa kunyunguduka kwepurasitiki uye nekupa yakanaka yekudzikisa kuita.
