1. Usati watanga muchina, zvakakosha kutarisa kana simba remuchina wehupfu rinopindirana nemagetsi e-extruder socket.Chete mushure mekusimbisa kuti hapana zvikanganiso ndipo magetsi anogona kubaiwa mukati.
2. Mushure mekunge poda yehupfu ichiiswa simba, pakarepo tarisa inotenderera inotenderera uye yekudziya system.Mushure mekusimbisa kuti hapana zvikanganiso, batidza magetsi ekudziya switch uye woomesa talc poda patembiricha ye150 ℃ (yakapera maawa 1.5 isati yasvika).Maminitsi makumi matatu isati yagadzirwa, dzikisa tembiricha kusvika ku60+20/-10 ℃ patembiricha isingaperi yekushandisa.
3. Gadzirira talcum poda yakakwana isati yagadzirwa.Huwandu hwehupfu hwe talcum hunofanirwa kunge huri 70% -90% yekugona kwemuchina wekupfuura poda.Panguva yekugadzira, tarisa kana huwandu hwetalcum hupfu hwakakwana kamwechete paawa, uye wobva wawedzera nekukasika kana isina kukwana.
4. Panguva yekugadzira, zvakakosha kuve nechokwadi kuti waya inopfuura nepakati pevhiri rega rega rehupfu hwehupfu kudzivirira hurombo husina hupfu hunopfuura hunokonzerwa nehafu-yakapedza chigadzirwa kudedera.
5. Kusarudzwa kwechiumbwa chemukati chemukati chehupfu yakavharwa waya: Ikudze ne 0.05-0.2M/M maererano neyakajairwa chiyero (sezvo upfu hwekuputira huchatora imwe gap, uye diki yemukati mold inogona kukonzera kutadza kutaridzika uye nyore kuputsika kwewaya)
1. Kusvuura kusina kunaka:
a.Hupfu hushoma, hupfu hwetalcum hauna kuoma zvachose, uye huwandu hwakakwana hwehupfu hwetalcum hwakaomeswa hunoda kuwedzerwa.
b.Kana chinhambwe chiri pakati pemukati nekunze mould chakanyanya kureba uye protrusion yakanyanya kuwanda, zvinodikanwa kudzikisa kureba pakati pemukati nekunze molds.
n.Iyo dhayamita yekunze yeiyo semi-yakapedzwa chigadzirwa stranding idiki zvakanyanya kuti isave nehupfu nyore: stranding uye extrusion inobatwa nehuwandu hwakakodzera hwekuburitsa mumiriri isati yaitwa hupfu.
2. Kuremara kwechitarisiko kunokonzerwa nehupfu yakawandisa:
a.Talcum poda inounganidza yakawandisa mumukati mold duct, ichivharira kushanda zvakanaka kwesemi-apedza zvigadzirwa uye kukonzera kushata kutaridzika.Izvo zvinodiwa kushandisa pfuti yemhepo kuvhuvhuta talcum poda mukati memukati mold duct
b.Kana bhurashi risati rabvisa yakawandisa talcum poda, iyo semi-yakapera chigadzirwa inofanira kuiswa pakati pebhurashi kuitira kuti bhurashi ribvise yakawandisa talcum poda.
c.Iyo yemukati mold idiki zvakanyanya: Nekuda kwekushandiswa kwakakura kwehupfu hwemukati mold kana ichienzaniswa newaya yehupfu (yeiyo yakafanana yakatarwa), zviri nyore kusarudza yemukati mold ine pore size 0.05-0.2M/M yakakura kupfuura zvakajairika panguva yekugadzirwa
3. Core adhesion:
a.Kusakwana kutonhora: Iyo yekunze mutsara wehupfu mutsara unowanzo gobvu, uye nekuda kwekusakwana kutonhora panguva yekugadzira, zviri nyore kukonzera core waya kunamatira.Panguva yekugadzira, chikamu chimwe nechimwe chetangi remvura chinofanira kuchengetedza mvura inotonhora yakakwana kuti iwane kutonhora kwakakwana
b.Insulated PVC inonyunguduka pakupisa kwakanyanya, zvichikonzera kunamatira kwewaya: waya yepakati inoburitswa, uye huwandu hwakakodzera hwekuburitsa mumiriri hunoshandiswa panguva yekubata.Isati yabudiswa, iyo inoshandiswa inoshandiswa isati yave yakasvibiswa, kana kuti kana ichibudiswa, kusungirirwa kunovandudzwa nekuve nehupfu.
