Inqubo yokukhiqiza umugqa we-extrusion webhodi le-foam le-PVC

Izinga lokushisa lokukhipha

Ukuze uthole amabhodi e-foam esikhumba e-PVC aqinile anezimbobo eziminyene nezifanayo, izindawo ezibushelelezi nezihlanzekile, izinga lokushisa lendawo ngayinye kufanele lilawulwe ngokuqinile ngesikhathi sokukhiqizwa kwebhodi le-foam le-PVC. ukukhishwa imigqa. Uma izinga lokushisa lomgqomo kanye nesikulufu liphezulu kakhulu, izinto ezisetshenziswayo zithambekele ekuqhumeni kwegwebu, okubangela ukuqhekeka kokuncibilika kanye nobuso obumahhadlahhadla bepuleti. Uma izinga lokushisa liphansi kakhulu, ukwenziwa kwepulasitiki kwezinto akuphelele, futhi ubuso bepuleti bungalingani; izinga lokushisa lomzimba wokuguquka kanye nomlomo we-die kufanele libe ngaphansi kwezinga lokushisa lokukhipha, kodwa izinga lokushisa eliphansi kakhulu lizokwenza izinga lokushisa lokuncibilika libe phansi kakhulu ukuze lilahlekelwe ukuqina futhi lelulwe liphuke, kanti izinga lokushisa eliphakeme kakhulu lizonciphisa amandla okuncibilika kanye nokuqina, kubangele ukuqhekeka kwebhamuza, futhi kukhiqize amaphutha angenalutho ebusweni bepuleti.

Ukukhishwa kwezinto ezibonakalayo ngokuvamile kudlula ezinqubweni ezintathu: ukushisa, izinga lokushisa elingaguquki, kanye nokulondolozwa kokushisa.

Indawo yokushisa itholakala engxenyeni engaphambili yembobo yokukhipha umoya yomkhiphi (ingxenye yokuqala yokudlulisa indawo kanye nengxenye yesibili yokucindezela indawo); indawo yokushisa engaguquki ingemuva kwembobo yokukhipha umoya (ingxenye yesithathu yokukhipha umoya kanye nengxenye yesine yokulinganisa indawo); indawo yokushisa ikakhulukazi yakhiwe ikhanda ledayi, umzimba wokuguquka, kanye nedayi. Izinto ezikuyo indawo yokushisa zidinga ukushisa okukhulu, ngakho-ke ukubekwa kwezinga lokushisa kwale ndawo kufanele kube phezulu kancane ukuze kuhlangatshezwane nezidingo zokwengeza ukushisa ngokushesha nokugcina indawo yokushisa ezinzile yebhareli. Ngenxa yokushisa kwangaphakathi okukhiqizwa ukucheba nokugoqa izinto yi isigaba sesethulo endaweni yokushisa engaguquki edlula izidingo zezinto zokwakha, indawo ngokuvamile ifakwe idivayisi yokulawula izinga lokushisa enezindlela ezimbili yokushisa nokupholisa ukulawula izinga lokushisa lomgqomo ukuze lihlale lingaguquki, okuqinisekisa ukwakheka okuvamile kwepulasitiki kanye nokubumba kwe-extrusion kwezinto zokwakha. Ngemva kokuba izinto zokwakha zidlule endaweni yokushisa engaguquki, seziguqukile ngokuphelele, futhi ukushisa kule ndawo akusekho. Ukuze kusungulwe ingcindezi yokuncibilika, kuyadingeka ukusetha amapuleti okushisa ukuze kwenezele ukushisa kwangaphandle.

Isivinini sokukhipha kanye nesikhathi sokuhlala

Umkhuba wokukhiqiza ukhombisa ukuthi ijubane lesikulufu lilingana ngqo nomphumela wokukhipha ipuleti futhi lilingana ngokuphambene nobuningi bepuleti. Uma ijubane lesikulufu liphezulu, ijubane lokukhipha lishesha, kanye nokwanda okusheshayo kokushisa kokuncibilika kwandisa ubunzima bokulawula inqubo, kodwa izinga lokufoma liyafana futhi ikhwalithi yobuso bomkhiqizo ilungile; ngokuphambene nalokho, lapho ijubane lesikulufu liphansi kakhulu futhi ijubane lokukhipha lihamba kancane, kuzobangela ukwenziwa kwepulasitiki okungekuhle kokuncibilika ukuze kuncishiswe ukusebenza kahle kokukhiqiza, futhi ukufoma eduze kwe-die lip kuzokwenza ubuso bepuleti bube lukhuni. Ngaphezu kwalokho, ikhwalithi yepuleti nayo ithintwa isikhathi sokuhlala kwezinto ezisebhakedeni le-extruder kanye nokufa. Uma isikhathi sokuhlala sifushane kakhulu, i-ejenti yefoma iyabola ngokwanele, okuholela epuletini elinobukhulu obukhulu; uma isikhathi sokuhlala side kakhulu, kulula ukufoma ngokweqile futhi izakhiwo zemishini zepuleti ziyancishiswa.

I-Extrusion Pressure

Isihluthulelo sempumelelo noma ukwehluleka kokwenza i-plate foaming sisekutheni ngabe ukulawulwa kwengcindezi yokukhipha kufanele yini. Ijubane lesikulufu, izinga lokushisa lokuncibilika, kanye nobude kanye nesilinganiso sokucindezela kwesiteshi sokugeleza kwangaphakathi kwe-die konke kunomthelela omkhulu ekucindezelweni kokukhipha. Ukwanda kwejubane lesikulufu kuphakamisa ingcindezi yokukhipha yokuncibilika, okunganciphisa ububanzi bamabhamuza futhi kwandise inani lamabhamuza, okwenza kube lula inqubo yokwenza i-foaming. Lapho izinto ezengeziwe zenziwe ngepulasitiki kahle, kokubili ingcindezi yokukhipha kanye nogesi kuyaqina; kanti lapho izinto zenziwe ngepulasitiki engafanele, ingcindezi yokukhipha iyashintshashintsha, ugesi we-motor uyakhuphuka futhi ungabi namandla. Ekukhiqizeni kwangempela, izinguquko kugesi wamanje kanye nogesi we-die zivame ukusetshenziswa njengesisekelo esibalulekile sokwahlulela ukuthi ukulawulwa kokushisa kokukhipha kufanelekile yini.
