Zvichienzaniswa nemamwe epurasitiki extruded zvigadzirwa, SUZHOU SUPXTECH kugadzirwa yakaderera-furo ganda PVC mapurasitiki zvigadzirwa haingodi yakanaka plasticization pasi kumwe kunyunguduka kumanikidzika, asi ane anofambirana tekinoroji zvinodiwa saizi, uwandu uye kufanana kwemaburi furo, uyewo ukobvu, kuoma, kupenya uye kupera kweganda.Hunhu hwemuviri unopupuma hauna hukama chete neformula uye zvigadzirwa, asi zvakare zvinokanganiswa zvakananga uye zvinodzivirirwa neshear kuita kweextruder screw, kunyunguduka, tembiricha, extrusion (traction) kumhanya, mold lip gap, mold gap, kutonhora. tembiricha yemvura nezvimwe zvinhu.Naizvozvo, zvichienzaniswa nezvimwe zvigadzirwa zvepurasitiki zvakaburitswa, zvigadzirwa zvemapurasitiki eganda foam zvine kumwe kuoma kwehunyanzvi, kubva pakuita uye dzidziso kune akawanda asina kugadziriswa matambudziko anofanirwa nenyanzvi dzeindasitiri kudzidza nekugadzirisa.

1, ganda furo PVC epurasitiki sheet kugadzirwa tekinoroji uye hunhu

Iko kuoma kwehunyanzvi mukugadzirwa kweganda rinopupuma PVC zvigadzirwa zvepurasitiki zviri kupupa.Kupupa ndiyo mhedzisiro yekuwedzera uye kuwedzera kwekunyunguduka viscosity, gasi kudzvanywa kunogadzirwa neanoita furo agent uye atmospheric pressure.

Kupupa kwefuro kunowanzopfuura nematanho matatu:

(1) Gasi rinopupuma rinonyungudutswa mumusanganiswa weplasticized yunifomu inonyunguduka pane imwe tembiricha uye kudzvanywa muextruder uye inosvika pakuzara kuumba bubble core;

(2) Iyo yakanyungudutswa yakanyungudutswa kubva mukufa, uye nekumanikidzwa kusunungurwa, iyo supersaturated yakanyungudika gasi nucleates, inowedzera uye inonaya, ichigadzira mayunifomu uye maburi maburi maburi mugomba reformwork;

(3) Pasi pekutonhodza kwechigadzirwa chekugadzira, zvigadzirwa zvinopupuma zvinosimbiswa uye kuumbwa.Yakanakisa mhando yeganda furo PVC epurasitiki zvigadzirwa zvine hunhu hweakawanda uye gobvu maburi maburi, madiki uye yunifomu, density uye ukobvu zvinosangana nezvinodiwa, kutaridzika kwakanaka, kuoma kwepamusoro uye kupenya.

2, ganda furo PVC epurasitiki bhodhi unhu zvinhu

Iwo makuru mbishi zvinhu zvinokanganisa zvakananga chimiro chepurasitiki bubble ndeye furo agent uye furo harmonizer.Izvo zvigadzirwa zvakaita senge stabilizer, lubricant, calcium carbonate uye extrusion process control inogona kusimudzira uye kuronga iyo inopupa mhando kune imwe nhanho.Nekuti tembiricha yepurasitiki yekunyunguduka mu extrusion process yezvigadzirwa zvinopupuma inofanirwa kunge yakadzikira zvishoma pane yekuora tembiricha yeanopupa mumiririri, iyo yakaderera avhareji dhigirii yepolymerization yePVC resin, inodzikira tembiricha yekugadziridza inodiwa kunyungudutsa plasticization.Kuti uwane zvigadzirwa zvepurasitiki zvakazara furo, iyo resin viscosity haifanirwe kunge yakanyanya kukwirira.Panguva imwecheteyo, zvichienzaniswa nezvimwe zvigadzirwa zvinoputika, nekuti chikamu chemuchinjikwa chekugadzira pepa chakafara, kubva kumusoro weextrusion mumuromo unofa kuti ugoverwe kuhupamhi hunosvika 1.3m, kuitira kufambisa kupararira nekuwedzera kwemabhuru. , kudzvinyirirwa kwechikamu chese chemuchinjiko chepepa kunofanirwa kurongeka, kunyungudika kwemvura kwakakwira, uye huremu hwemamorekuru eresin kazhinji hudiki.Zvakadai seSC-7 kana SC-8 kumiswa nzira yakasununguka resin inonyanya kukodzera.SUZHOU SUPXTECH
