PVC furo mapuranga anoshandiswa mune ese mafambiro ehupenyu, kunyanya mune zvekuvaka. Unoziva here kuti ndeapi matambudziko angamuka panguva yekugadzirwa kwePVC foam board? Pazasi, mupepeti achakuudza nezvavo.
Zvinoenderana neakasiyana furo reshiyo, inogona kupatsanurwa kuita yakakwira furo uye yakaderera furo. Zvinoenderana nekupfava uye kuoma kwefuro kugadzirwa, inogona kupatsanurwa kuita yakaoma, semi-yakaoma uye yakapfava furo. Zvinoenderana nesero chimiro, inogona kukamurwa kuita yakavharwa-sero foam mapurasitiki uye akavhurika-sero foam mapurasitiki. Mashizha akajairwa ePVC foam akaomarara akavharwa-sero akaderera-furo mapepa. PVC furo mapepa ane zvakanakira makemikari kusaora, kuramba mamiriro ekunze, murazvo wemoto, nezvimwewo, uye anoshandiswa zvakanyanya muzvinhu zvakawanda, kusanganisira zviratidziro, zviratidzo, zvikwangwani, zvikamu, mapaneru ekuvaka, mapaneru efenicha, nezvimwewo. kutungamirira kumasero makuru mupepa refuro uye zvikamu zverefu refu. Nzira yakananga yekutonga kana simba rekunyunguduka harina kukwana kuenda kuseri kwema roller matatu uye wodzvanya ndiro yakaputirwa pakati pepakati neminwe yako. Kana iyo yakanyunguduka simba rakanaka, unogona kunzwa elasticity kana uchidzvanya. Kana zvakaoma kusimuka mushure mekumanikidzwa, simba rekunyunguduka harina kunaka. Nekuti iyo screw chimiro uye nzira yekutonhora zvakasiyana, zvakaoma kutonga kana tembiricha ine musoro. Kazhinji, mukati memutoro unobvumirwa weextruder, tembiricha munzvimbo 3-5 inofanira kunge yakaderera sezvinobvira. Kuti uwane yunifomu yakafukidzwa zvigadzirwa mumapepa efuro, zvinodikanwa zvakare kuve nechokwadi chekuti PVC zvinhu zvine simba rakanaka rekunyungudika. Naizvozvo, kunaka kweiyo furo regulator kwakakosha zvikuru. Semuenzaniso, mukuwedzera kumabasa ekutanga e-general-purpose processing aid, iyo inopupuma regulator inewo huremu hwemamorekuru uye kunyunguduka simba, izvo zvinogona kuvandudza zvakanyanya kunyunguduka kwePVC musanganiswa uye kudzivirira mabhuru uye kuputika. , zvichiita kuti pave neyakafanana sero chimiro uye yakaderera chigadzirwa density, uyewo achivandudza pamusoro gloss chigadzirwa. Ehezve, dosi yeyero inopupa furo uye chena inopupuma mumiriri inofanirawo kufananidzwa.
Mukutaura kwemapuranga, kana kugadzikana kusina kukwana, kunokanganisa bhodhi rose uye pamusoro pebhodhi kuti iite yero, uye foam board ichava brittle. Mhinduro ndeyekudzikisa kupisa kwekugadzirisa. Kana pasina kuvandudzwa, iwe unogona kugadzirisa chimiro uye zvakakodzera kuwedzera huwandu hwekudzikamisa uye lubricant. Iyo stabilizer ndeye lubrication system yakavakirwa pamafuta anotengeswa kunze kwenyika kuti awedzere kuyerera kwechinhu. Zvinhu zvinodzivirira kupisa zvine mvura yakanaka. , kunaka kwekudzivirira kupisa; kusimba kwemamiriro ekunze kwakasimba, kupararira kwakanaka, kuomesa uye kunyunguduka mhedzisiro; yakanakisa kugadzikana, plasticizing fluidity, yakakura kugadzirisa siyana, yakasimba applicability uye yebetsero mukati uye kunze lubrication. Lubricant ine yakaderera viscosity, yakakwirira yakakosha zvivakwa, yakanakisa lubricity uye kupararira, uye inoshandiswa zvakanyanya mukugadzira epurasitiki uye mamwe maindasitiri. Iine yakanaka yemukati uye yekunze lubrication mhedzisiro; ine kuenderana kwakanaka ne polyethylene, polyvinyl chloride, polypropylene, etc. Inoshandiswa se dispersant, lubricant uye inopenya panguva yekuumbwa kwePVC profiles, pombi, pombi fittings, PE uye PP, kuwedzera dhigirii repurasitiki, kuvandudza kuoma uye kutsetseka. pamusoro pezvigadzirwa zvepurasitiki, uye inogona kuchinjwa imwe neimwe, zvichiita kuti zvive nyore kukurumidza kuwana matambudziko Chero kwaunenge uri, gadzirisa dambudziko nekukurumidza sezvinobvira. Panyaya yemafuta ekuzora, kusakwana kwekunze kutsvedza kunoratidzwa mukuti tembiricha iri munzvimbo 5 yeextruder inonetsa kudzora uye nekupisa zviri nyore, zvichikonzera kupisa kwakanyanya mukati meiyo converging core, matambudziko akadai semabhuru makuru, mabhuru, uye kutsvuka pakati pepuranga, uye pamusoro pepuranga hachina kutsvedzerera; Kunyanya kutsvedza kuchaita kuti kunaya kuve kwakakomba, izvo zvinozozviratidza muchimiro mukati me mold uye kunaya kwekunze kutsvedza pamusoro peplate. Icharatidzawo sezvimwe zviitiko zvemunhu zvinofamba zvichidzoka zvichienda zvisingaite paplate pamusoro. Kusakwana kwemukati kutsvedza kunoreva kuti zvakaoma kudzora ukobvu hwebhodhi, iro rakakora nepakati uye rakatetepa kumativi ese. Kunyanya kutsvedza kwemukati kunotungamira zviri nyore kune tembiricha yakakwira mukati meiyo converging core.
