Maitiro ekugadzira mutsetse wekuwedzera wePVC foam board

Kupisa kwekunze

Kuti pave nemabhodhi ePVC eganda akaomarara ane maburi akakora uye akafanana, nzvimbo dzakatsetseka uye dzakachena, tembiricha yenzvimbo yega yega inofanira kudzorwa zvakanyanya panguva yekugadzira bhodhi rePVC remafuro. extrusion mitsetse. Kana tembiricha yebharero nescrew yakakwira zvakanyanya, zvinhu zvacho zvinogona kuputirwa furo, zvichikonzera kupwanyika uye pamusoro peplate pakamanikana. Kana tembiricha yakadzikira zvakanyanya, purasitiki yezvinhu hazvina kukwana, uye pamusoro peplate hapana kuenzana; tembiricha yemuviri wekuchinja uye muromo wedie inofanira kunge yakaderera pane tembiricha yeextrusion, asi tembiricha yakaderera ichaita kuti tembiricha yekunyunguduka ive yakaderera zvakanyanya kuti isanyanya kusimba uye itambanudzwe, nepo tembiricha yakakwira ichideredza simba rekunyunguduka uye kusimba, zvichikonzera kuputika kwemabubble, uye zvichikonzera zvikanganiso zvisina basa pamusoro peplate.

Kuburitswa kwezvinhu kunowanzoitwa nenzira nhatu: kupisa, tembiricha isingachinji, uye kuchengetedza kupisa.

Nzvimbo yekupisa iri pamberi pechiteshi chekubuda kwemhepo (chikamu chekutanga chekuendesa uye chikamu chechipiri chekumanikidzwa kwenzvimbo); nzvimbo yekupisa inogara iripo iri kumashure kwechiteshi chekubuda kwemhepo (chikamu chechitatu chechiteshi chekubuda kwemhepo uye chikamu chechina chemita yenzvimbo); nzvimbo yekudzivirira ine musoro wekufa, muviri wekuchinja, uye dhi. Zvinhu zviri munzvimbo yekupisa zvinoda kupisa kwakawanda, saka tembiricha yenzvimbo iyi inofanira kunge yakakwira zvishoma kuti isvike zvinodiwa zvekuwedzera kupisa nekukurumidza uye kuchengetedza tembiricha yakagadzikana yebharero. Nekuda kwekupisa kwemukati kunogadzirwa nekuchekwa nekukungurutswa kwezvinhu ne screw munzvimbo inodziya nguva dzose inopfuura zvinodiwa nezvinhu, nzvimbo iyi inowanzo shongedzerwa nemudziyo wekudzora kupisa nekupisa une nzira mbiri kuti udzore tembiricha yebharero kuti irambe yakadaro, zvichiita kuti purasitiki irambe yakadaro uye kuumbwa kwechinhu chacho kubude. Mushure mekunge chinhu chacho chapfuura nepakati penzvimbo inodziya nguva dzose, chave chave purasitiki zvachose, uye kupisa munzvimbo iyi hakuchina. Kuti pave nekumanikidzwa kwekunyunguduka, zvinodikanwa kugadzira maplate ekudziya kuti awedzere kupisa kwekunze.

Kumhanya kwekubvisa uye nguva yekugara

Maitiro ekugadzira anoratidza kuti kumhanya kwe screw kunoenderana zvakananga nekubuda kweplate uye kunoenderana nehuremu hweplate. Kana screw yakakwira, kumhanya kwe screw kunowedzera, uye kuwedzera nekukurumidza kwekushisa kwekunyunguduka kunowedzera kuoma kwekudzora maitiro, asi dhigirii re furo rakafanana uye mhando yepamusoro yechigadzirwa yakanaka; Kusiyana neizvi, kana kumhanya kwe screw kwakaderera zvakanyanya uye kumhanya kwe extrusion kuchinonoka, zvichaita kuti plasticization yekunyunguduka isashande zvakanaka kuderedza kushanda kwekugadzira, uye furo pedyo ne die lip kuchaita kuti pamusoro peplate pave nehuremu. Pamusoro pezvo, hunhu hwe plank hunokanganiswawo nenguva yekugara kwezvinhu mu extruder barrel uye die. Kana nguva yekugara iri pfupi, furo rinoora zvisina kukwana, zvichikonzera plank ine huremu hwakawanda; kana nguva yekugara yakareba, zviri nyore kupumha furo zvakanyanya uye hunhu hwe mechanical hweplank hunodzikira.

Extrusion Pressure

Chinokosha pakubudirira kana kukundikana kwe plate furo ndechekuti extrusion pressure control yakakodzera here. Kumhanya kwe screw, tembiricha yekunyunguduka, uye kureba uye kumanikidzwa kwe die internal flow channel zvese zvine chekuita zvakanyanya nekumanikidzwa kwe extrusion. Kuwedzera kwe screw speed kunowedzera extrusion pressure yekunyunguduka, izvo zvinogona kuderedza dhayamita yema bubbles uye kuwedzera huwandu hwema bubbles, zvichiita kuti furo rifambe zvakanaka. Kana zvinhu zvakawedzerwa zvaiswa plastic zvakanaka, die pressure ne current zvinogadzikana; nepo kana zvinhu zvisina plasticized zvakanaka, die pressure inochinja, motor current inowedzera uye inova isina kugadzikana. Mukugadzirwa chaiko, shanduko mu host current ne die pressure dzinowanzo shandiswa sehwaro hwakakosha hwekutonga kana extrusion temperature control yakakodzera.
